BACKGROUND OF THE INVENTION
[0001] The current vertical washing machines of clothes use agitators, either of the oscillating
type or propeller type, to scrub the clothes and produce streams inside the washing
tub which pass through the fabric and try to loose the particles adhered thereof;
but these streams are not stronger and effective to go through the innermost fibers
of the threads, therefore the time of washing can be more prolonged and to spend more
energy of the necessary. These washing machines require mechanisms of machined transmission
and speed reduction to produce the oscillating motion of the agitation impeller or
in the case of propeller thrusters; these tend to entangle so much the clothes. In
addition, during the wringing of the clothes by centrifugation, the tub rotates supported
by a fixed central shaft; this makes difficult the balance during the rotation.
[0002] This invention is an improvement to the patent No.
5.953.939 registered by the authors of this in the United States of America. The purpose of
this invention is to improve the machines for washing, rinsing and wringing clothes;
in addition to take advantage in some way the phenomenon of cavitation for a more
efficient washing. The invention is referred to a machine for washing clothes by means
of a recirculating pumping system, which uses a special exhaust to produce cavitation
inside the washing tub and, for the wringing it has a self-balanced rotation system
which makes that the tub turns on the virtual shaft which passes through the centre
thereof. With these improvements the purpose is to obtain a deeper and uniform washing,
to circulate the clothes by the cavitation area inside the tub; besides to decrease
the losses of pressure in the hydraulic circuit. Also, as variants, it is showed how
to apply all these new ideas to a horizontal or front load washing machine and an
industrial washing machine.
[0003] In this document are presented the basic ideas of the invention and their variants,
with the purpose to combine in the most practical way the most ideal to get a washing
and wringing machine which increases the efficiency and speed of washing, and saving
time and energy during its operation.
DESCRIPTION
[0004] In the following description and in the attached drawings the characteristics of
the invention are detailed, indicating the portions of this one with the same reference
signs as in the description as in figures; the portions with equal function on the
different figures are marked with the same number in each of them.
Figure 1 represents a first version of the washing machine, in which is described,
in general, the recirculation pumping system which is used for squirting inside the
washing tub and propelling a turbine which, by means of a speed reducer, it moves
a rotary washing system which produces the circulation of the clothes inside the washing
tub. Furthermore, it is showed the centrifuging which makes rotating the floating
tub on the virtual shaft passing through its center of gravity. By simplicity, the
exhaust system is not showed.
Figure 2 shows a special exhaust and a rotary washing system which is impelled by
a jet reaction; this jet is sent towards a dragging zone to push the clothes inside
the tub.
On Figure 3 is observed a first version of the use of the rotary washing system of
Figure 2, as well as a first form to arrange, staying fixed on the system, the special
exhaust and the steam chamber which feeds it to produce steam bubbles which produce
cavitation in the sine of the washing tub.
Figure 4 is a variant of the rotary washing system of Fig. 3, used to reduce friction
losses in the pipeline. In this version, The exhaust rotates along with the rotary
washing system, while the steam chamber remains fixed, therefore it is inserted a
rotary sealing system, mechanical-type seal, on the tube which drives the steam between
the static steam chamber and the suction of the exhaust rotating.
Figure 5 is other similar system to the previous, in which the steam chamber and the
exhaust rotate together to avoid the use of a rotating seal, besides employing a planetary
reducer to transmit the rotation to the system.
Figure 6 describes a mechanism so that the rotating of the washing system being paused.
In Figure 7, the feeding to the rotary washing system is made below of the tubs. In
this case, the rotary washing system moves laterally together with the centrifuging
tub, during this cycle; therefore Fig. 8, as continuation of Fig. 7, shows mechanisms
to allow the displacement in the case of using a speed reducer.
On Figure 9 the same system of Fig.7 is showed, except that in this figure the rotary
washing system remains centered with the geometric shaft of the washing machine and
the steam chamber is fixed.
Figures 10 and 11 describe a system for better balance of the centrifuging tub.
The Figure 12 is a mechanism, in addition to the flotation system, to support the
tub during the centrifuging cycle in its free rotation, on any virtual shaft passing
through the center of gravity of the tub and the clothes for wringing.
Figure 13 is a variant of figures 7 or 9, which uses the support of Figure 12; and
a pump is used for the washing pumping circuit and another pump for centrifuging cycle;
both pumps impelled by the same motor.
On Fig 14 is showed a system to eliminate loose threads coming out of clothes.
On Figure 15 is illustrated how to implement the new washing and centrifuging system
described in the previous figures, in a new washing machine of tube or cylinder type
or horizontal shaft or frontal load type cylinders.
Figure 16 is equal to Figure 15, except that the washing system changes a little.
On Figure 17 is used the basic idea of Figure 12 to the case of Figures 15 or 16;
and Figures 18 and 19 are variants of the same idea applied to a washing machine of
vertical axial shaft as of Figures 7, 9 or 13.
On Figures 20 or 21 is used the system of Figures 18 or 19 for a version of the washing
machine of Figure 3 with less losses.
The Figure 22 is an industrial washing machine for washing large quantities of clothes,
and Figure 23 is the wringing system of the washed clothes in the system of Fig. 22.
Figure 24 is a second version of the industrial machine of Fig 21 in which the wringing
is made by centrifuging the clothes.
Figure 25 is a version of Figure 9 and Figure 26 is an optional system of a planetary
speed reducer which produces an oscillating motion which put together the blades to
produce the circulation of the clothes inside the tub.
[0005] Support structures, controls, cabinet, etc., for simplicity are not showed in the
figures.
- Returning to Figure 1, it is seen that the new washing machine has a main tub (7) within which is placed
an internal tub (14) which has about half of the height of that the nodding of the
internal tub being when it rotates floating, within the main tub, with the clothes
to squeeze seated at its core, within the main one. A closed annular chamber (28)
forms the side of the internal tub (14) and contains, as a counterweight to balance
on the centrifuging cycle, a certain amount of a heavy and fluid material, such as
a kind of liquid or small spheres of smooth material. The internal tub is housed in
a broadening of the lower half of the main tub (7), so that the diameters of both
tubs are sufficiently matched. The peripheral separation between the broadening stage
of the main tub and the upper edge of the internal tub is covered to avoid the passage
of clothes, by a kind of annular floodgate (31) with section on "L"-shape, whose vertical
portion adjusted slightly adjusted to the inner of the main tub; and the horizontal
portion is supported by own weight, on the upper edge of the internal tub. The horizontal
portion of the "L" has pasted below a plate (30) of antifriction material, which seats
and slides on another plate (30) of the same material fixed at the upper edge of the
internal tub, when it rotates.
[0006] In the center of the core of the internal tub (14) it is lifted up a wide vertical
tube (11) which terminates, at its upper, in the box of a planetary speed reducer
(2) and, through the tub, it is extended downward into another tube (20) to drain
the water from the tub. Under the core level of the tub, a vertical and axial turbine
(26) is within a broadening, on casing shape of the vertical tube (11) so that the
turbine shaft (32) impels to the planetary reducer and entering to this through a
bearings box (33) with seal against leakage of the lubricant. On the other hand, centered
shaft (34) of the reducer output (2) is welded, by above of this one, to the center
of the upper lid (35) of a second wide tube or central hollow post (1) hereinafter
called central post. This central hollow post is outer, concentric and freely adjusted
to the wide tube width (11), also it is hermetically closed only in its upper portion
with such lid (35); around this central post are fixed one or two helical plates (4)
which to rotate the post they serve as screw, to be pushing the clothes downward.
Also are fixed to the central post (1), at the bottom of the tub, radial blades (12),
which when rotate through towards the periphery the clothes which are falling to the
bottom of the tub. The central hollow post, the helical plate welded to it and the
system which makes rotate to both to move the clothes inside the tub, form the rotary
washing system, in this figure and following.
[0007] The washing and rinsing cycles are made by means of a closed circuit of pumping.
The circuit consists of a pump (18) placed under the tubs and with its discharge connected,
through the tube (8) and the control valve (13), to a nozzle (6) or a special exhaust
(not shown in the figure by simplification) which discharged in suitable direction
a strong water jet inside the tubs. By the orifices (10), that both tubes, (11) and
(1), have at the upper of their periphery, the water flow continuously gets out of
the internal tub through central tube (11) and the tube of evacuation (20) to impel
the rotation of the turbine (26). By means of the speed reducer (2), the rotating
motion of the shaft (32) of the turbine is transmitted, with smaller speed and greater
force, to the hollow central post (1) to move the clothes with the blades and the
helical plates. The upper of both tubes lacks of orifices and is closed in order to
when fill with water the tub a compressed air chamber (3) be formed within them which
prevents that the water reaches to the system of the reducer. In order to facilitate
more the movement of the clothes, the tubs have in their inner periphery other helical
plates (5) which, with the circular motion of the water flow within the tub, cause
that the clothes tend to ascend by the sides of the tubs.
[0008] The water which gets out of the turbine discharge continues flowing through the tube
of evacuation (20) of the internal tub and, getting out of this one, it enters directly
to the suction tube (19) of the pump (18) that returns the water flow to those to
complete the closed circuit of pumping.
[0009] The wringing cycle is carried out through the centrifuging of the clothes. For this,
it is started by evacuating the water of the tubs by means of some draining system,
not indicated on fig. 1, until the water level decreases as far as below of the bottom
of the tubs, so that the water which is in the internal tub (14) gets out through
the retainer or check valves (27) at the bottom of the tub. To finish evacuating the
water at such level, becomes to introduce water so that the space between the two
tubs be filled until certain predetermined level (29); due to the retainer valves
(27) of the internal tub, the water will be not introduced again in this tub, which
will be floating in the water that there is between both tubs. The evacuation tube
(20) of the internal tub also has a retainer valve (15) with floating plugger, which
serves to when introducing again water between the two tubs and during centrifuging
the same water it does not enter again for this tube to the internal tub.
[0010] Floating the internal tub, this is rotated by means of a special turbine special
and similar to a horizontal turbine Pelton-type. This turbine consists of a vertical
box (25), of almost cylindrical shape, which is centrally joined at the bottom of
the tub or to the vertical evacuation tube (20) and is crossed by this one; at the
side of the box are introduced at the half a distributed series of simple cavity-radial
buckets (24) slightly tilted downwards with similar form to a ladle curved almost
180 °, which allow free way to the inner of the box only through their cavities. Moreover,
as it is observed in the cutting AA', the internal edges of the buckets (24) are directed
and finish in a series of holes (21) which the evacuation tube (20) has in its side
of that zone, thus the water of the jets that impel to the buckets is discharged by
such holes within the tube. These water jets are thrown by a series of nozzles (17)
on the cavities of the tangential-shape buckets; therefore the impulse applied on
the buckets by the jets produces the rotation of the internal tub (14)
[0011] To make work the turbine described on the above paragraph, the control valve (16)
of the nozzles (17) connected to discharge of the pump (18). The water flow which
impels the turbine is drained by the evacuation tube (20) on the input of the suction
tube (19) of the pump (18), so that this same flow being pumped again towards the
nozzles (17), and be established the closed circuit which keeps the rotation of the
turbine of pumping The water which wets the clothes and is centrifuged is evacuated
of the internal tub by the holes (9) of the tub which are above of the flotation level.
All the system which produces the rotary impulse of the tub is lodged in a cylindrical
casing (23) or centrifuged chamber which is centrally joined to the bottom of the
main tub (7), as a continuation of this one, and whose bottom is connected to the
suction tube (19) of the pump.
[0012] Since the internal tub (14) does not rotate supported by a rigid shaft which supports
this in its geometric center, this shall rotate, due to its flotation, on the virtual
shaft which passes through the center of gravity of the set of the tub and the clothes
for being wringing. Although the internal tub (14) rotates in balanced form or without
vibrations on this virtual shaft, if the clothes are not symmetrically distributed
inside the tub, the virtual shaft displaces from the geometric shaft, causing that
the tub shakes and oscillates by not rotating on its geometric shaft; therefore it
may hit or rub with the mean tub (7). This undesirable effect is diminished by means
of the fluid and heavy material contained in the closed annular chamber (28) which
forms the side of the tub (14), since when beginning to rotate the tub the liquid
within this chamber is accumulated from the side opposed to the slipping of the virtual
shaft respect to the geometrical. When the weight of the accumulated fluid in a side
of the chamber counteracts to the unbalanced weight of the clothes in the opposite
side, the distance between the virtual rotary shaft and the geometric center will
decrease, although it will not be null and it will be in an intermediate point, since
when approaching to these shafts it is redistributed, until certain point, the fluid
inside the balance chamber (28), but improves the oscillation and the shaking. Between
the sides of the tubs are placed bearings with shock absorbers, not shown in the figure,
to support frictions and small impacts between the tubs. Later on, some methods are
indicated to avoid the redistribution of counterweight fluid.
[0013] So that the flotation of the internal tub inside the main tub be stable, is added
a flouting counterweight (22) in the lower end of the evacuation tube (20); in this
form the meta-center keeps fixed between the flouting centre and the center of gravity
of all the system of the internal tub, including wet clothes.
- Figure 2 illustrates a rotary washing system, similar to that described in the above figure,
which uses the impulse of a jet reaction to rotate the central post with its helical
plate, in such a way that the rotation of the post is combined with a positive push
of the same squirt upon the clothes, in order to cause its movement into the tubs
and its circulation through the area where cavitation occurs. In the same drawing
is described the aforementioned special exhaust.
[0014] In the upper portion of figure 2 the device is observed de device to produce the
positive push on the clothes, which consist of a dragging zone of the clothes limited
by two warped surfaces, (44) and (45), separated to some distance facing each other,
with opposing curvatures and certain convergence degree between both; in such a way
that the clothes, which are in the limited space by both surfaces, can undergo a push
or effective drag by a water jet that flows between both surfaces in direction of
the convergence and which gets out of a nozzle, a tube or from the exhaust illustrated
in the same figure , as a jet producer in this case.
[0015] Also in the upper portion of the figure it is seen that the special exhaust is comprised,
firstly of a conical tube or Venturi (39) fed by a tube (40), which increases the
speed and lows the water pressure to a negative pressure. The outlet end (41) of the
Venturi, of smaller diameter, is enclosed and surrounded by a small closed cylindrical
box or suction chamber of the exhaust (37) communicated, through a small suction tube
(38), with the upper portion of a closed chamber (57) (fig. 3), described later, where
low pressure steam is generated. The suction chamber (37) ends in an output tube (36)
with an equal diameter to the final outlet diameter (41) of the Venturi and aligned
with the output of this one; in order to absorb the steam there is a very small clear
(42) between the final extreme (41) of the Venturi (39) and the initial extreme of
the output tube (36). The output tube (36) of the exhaust has in its beginning a short
and small internal contraction that form the throat (43) of the exhaust and then it
keeps its normal diameter at full length, to keep the vacuum pressure produced by
the Venturi and the throat, contrary to a normal exhaust which ends in a diffuser.
The water fed by the tube (40) to the Venturi (39) of the exhaust and the steam sucked
by this from the steam chamber are launched by the output of the exhaust (36) in a
jet of water mixed with steam bubbles a vacuum pressure, which collapse due the atmospheric
pressure to be discharged into the tub, causing implosions and shock waves which wash
the clothes.
[0016] In the bottom of Figure 2 is showed the system that produces the impulse to rotate
the center post (1) with its helical plate (4), by the jet reaction in a rotary tube
(48) fed by the fixed tube (8) connected to the pump discharge. To the left of the
bottom of the figure it is observed a first type of rotary coupling between these
two tubes, which allows the rotation of the first one over the second one, consisting
in introducing some distance to the end of the feeding tube (8) within the rotary
tube (48), with a fine adjustment between both, as a pillow block. The axial displacement
between both tubes is limited mounting on the fixed tube (8) a brake shoe (52), in
disc shape with smooth surfaces, which is linked or slightly imprisoned between a
pair of discs or rotary plates, also with smooth surfaces, which are joined or linked
to each other in their periphery. The upper plate (51), with a bushing slightly fitted
to the fixed tube, it supports the rotation of the system on the upper surface of
the brake shoe (52) and the bottom plate (50) is joined to the rotary tube (48), in
order to support it.
[0017] Another version of the rotary coupling between the fixed tube (8) and the rotary
tube (48) is illustrated in the drawing to the right of the previous version. In this
case, the fixed feeding tube (8) ends in a cylinder (54), wide and hollow, which at
its inner has screwed the external diameter of a large bushing (53), which serves
as a pillow block to the rotation of the rotary tube (48), for which the upper end
of this tube is introduced within the bushing with a fine adjustment. This bushing
(53) is smoothly fastened, in its inferior face, by a brake shoe (52) mounted on the
rotary tube and, in its upper face, by another screwed bushing (55), as a nut, in
the end of the same tube.
[0018] In the left inferior portion of Figure 2 it is observed that the vertical and centered
rotary tube (48) within hollow post (1), has in its bottom a first (46) fold to 90°
and it continuous, after to get out by a hole at the post, with a second (47) horizontal
fold, also near to 90° which places to the end(40) of exit of the tube on perpendicular
position to the rotary shaft of the own tube, and some distance from this shaft and
directing the water jet which launch by such end towards the dragging area, formed
between the surface(44), terminal of the helical plate (4), and the surface (45) of
another inferior plate welded to the same central post (1), in order that the water
jet drags the clothes which pushed by the rotation of the helical plate, they gradually
stay on this space.
[0019] The distance and perpendicular direction with respect to the shaft of the rotary
tube (48), with which the water jet gets out by the end (40) of the same tube, according
to their folds to 90 °, it causes that this jet, by reaction, pushes the end of the
tube backwards and impels the rotation of this. The transmission of the rotation of
the rotary tube to the central post can be directly done, joining with arms (49) the
post to the rotary plate (50) of the tube, or by means of a speed reducer to increase
the torque and to reduce the speed of the central post, so that the helical plate
(4) is moving the clothes towards the dragging zone.
- The figure 3 is a washing machine by recirculating pumping with washing and centrifuging systems
similar to those described in Fig. 1, except that the rotary washing system is impelled
with a tube which rotates by jet reaction, as the described in Fig. 2; in addition,
it is showed the use of the special exhaust in the rotary washing system and the disposition
of the steam chamber (57) which produces this to negative pressure. In this case the
steam chamber and the exhaust remain fixed, joined to the feeding tube (8), to be
able to directly connect the electrical power to the resistance (56) that heats the
water in the steam chamber and feeding directly the produced steam to the suction
chamber of the exhaust. At the bottom of figure 3, it can be seen an amplification
(67) of the exhaust and the steam generating system, which are indicated with the
same number (67) at the upper of the tub (7).
[0020] The feeding tube (8) for the washing centrally gets into the inner of the tubs, (7)
and (14), by above of these, and it is directly connected with the conical tube or
Venturi (39) of the special exhaust, in such a way that this together with its suction
chamber (37), crosses and keep centrally lodged inside the steam chamber (57). The
steam chamber is a cylindrical box, hermetically closed and lodged within the central
post (1), wherein the water is heated by means of the electrical resistance (56) to
generate steam to the low pressure of the exhaust; this steam is suctioned by the
suction chamber (37) of the exhaust through the small tube (38) whose nozzle stays
at the upper of the steam chamber to draw in only this. Below the core centre of the
steam chamber (57) the output tube (36) outstands of the exhaust to coupling, by means
of the support brake shoe (52) and the rotary plates (50) and (51) as in Fig. 2 with
the rotary tube (48) which keeps the same small diameter of the output tube (36),
to keep the high speed and the low pressure of the water and steam flow produced by
the exhaust, as it was mentioned. Joined by and arms (49), the rotary tube (48) drags
in its rotation to the central post(1); furthermore the bottom and the folds (46)
of the same tube are housed within a broadening of the bottom of the central post
o cover (58) in bell-shaped, in order to avoid that the clothes stuck with such folds.
The end (40) of the rotary tube (48) outstands of the cover (58) by a hole in a radial
and vertical plane (66) that interrupts the bell shape, so that the water jet and
steam bubbles, which are discharged by such extreme, go towards the dragging area
formed between the surface (44) of the helical plate (4) and the plate (45), wherein
the bubbles are collapsed causing shock waves which wash the clothes.
[0021] Within the internal tub (14) another additional tub is placed (59), separated a little
and with a series of holes (10) by which is leaving the water that the tube (40) discharges
within the internal tub. Through the space (60) between the cores of the two tubs,
the water goes out of these through a evacuation tube (20) which begins from the core
center of the internal tub (14), and it extends downwards until ending very near,
upon the input of the suction tube (19) of the pump (18), to complete the closed pumping
circuit during the washing cycle.
[0022] In order to fix the flotation level (29) in Figure 3, firstly the water of the tubs
is evacuated (62) by means of a small pump (62) which discharges (63) to the general
drainage and whose suction (64) is connected to an output (65) of the main tub (7),
which is at the side of this to the same height that the prefixed flotation level
(29). When the water level comes at the height of the opening (65) cannot be continued
evacuating the water and the level (29) of the same one does not get down anymore;
in this point, main pump (18) starts and begins to suck, through its suction tube
(19), the water of the centrifuging casing core (23) simultaneously that it discharges
this same water in jets launched by the nozzles (17) upon the Pelton turbine, which
begins to rotate and return the water used to the core of the casing (23) through
the tube (61), coaxial and external to the tube (20), to be recirculating again by
the pump. Since the water passage of the evacuation tube (20) to the suction tube
(19) is more direct, this one will suck more water of the inner of the tube (20) that
water evacuated by the turbine. Thus, the tube (20) will be emptied at certain volume,
same which will go out from the internal tub (14), but it could not retake it due
to retainer valve (15) inside the own tube; in this way, the volume of water evacuated
of the internal tub increases, in equal amount, the volume of water which there was
between the two tubs, therefore the water level between them will increase, exceeding
the opening (65). In this condition, the draining pump (62) come back to work removing
the excess and repeating the cycle until the internal tub be empty and floats the
rest of the cycle.
[0023] In the figure 4 only it is drawn, by simplicity, a rotary washing system which is a variant of the
system of figure 3, which is used if the pressure losses in this are big. In Figure
3 the rotary tube (48) has a small diameter, equal to the output of the exhaust (36),
which can produce big friction losses due to the high speed of the water in the tube
and its curvature. To limit these losses, keeping a big diameter in all the rotary
tube (48) , in Fig. 4 the exhaust is installed on the end (40) of the tube (48), after
his double curvature (46) (47), connecting such extreme (40) directly to the Venturi
(39) of the exhaust.
[0024] The cylindrical closed steam chamber (57), which is fixed to be able to feed directly
to the electrical resistance (56), is housed within the central post (1) and it is
centrally crossed and supported by a passing wide tube (69) which is continuation
of the feeding tube (8). The lower end of the wide tube (69) outstands of the core
of the steam chamber (57), the enough to be articulated with the rotary tube (48)
by means of a rotary coupling with the brake shoe (52) linked by the rotary plates,
lower (50) and upper (51), as it was described.
[0025] The connection between the fixed steam chamber and the suction of the exhaust, which
rotates with the system, consists of a thin vertical tube (68) which, with its upper
end inside the chamber, sucks the generated steam and then it gets into the side of
the passing tube (69), in such a way that its lower end stays concentric or coaxial
with this tube, and connected to the borehole of a small vertical bushing (70) of
thick wall, fixed by means of an arms (73) to the inner of the wall of the passing
tube (69). Below the bushing (70) it is introduced in the borehole of this second
thin and short tube (76) which can rotate inside the bushing, slightly adjusting its
diameters as a pillow block. This second short tube (76) is connected, through a small
flexible hose section (72), with a equal third tube (38) which goes down centrally
until being placed within the rotary tube (48), wherein it is fastened by a ring (74)
fixed to the inner of the rotary tube by another arms (73); then, the third tube (38)
goes out from the rotary tube (48) through the wall thereof and it is directly connected
with the suction (37) of the exhaust. The sealing of the connection between the fixed
portion and the rotary portion of the duct of the steam is made with a mechanical
or rotary seal comprising a disc (71) or ring that has its upper surface polished
and is tightly mounted around the second thin tube (76), which is pressured against
the lower face, also polished, of the bushing (70), pushed by a spring (75) which
at the lower is supported against the ring (74) which holds the third tube of steam
conduction (38). The flexible hose section (72) serves so that the spring can push
the sealing disc. In such a way, the steam sucked by the fixed tube (68) can flow
by the tube (38), which turns with the exhaust, towards the suction chamber (37) of
this. The disposition of the other components of the rotary washing system is equal
than in Fig. 3.
[0026] As an option, the steam chamber (57) of Figures 3 and 4 can be fixed to any other
place outside the central post, using a connection tube (38) or (69) with the suction
of the exhaust of enough length.
[0027] The figure 5 is similar to the washing system described on Figure 4 and it shows, in addition,
the tubs (7) and (14). The difference consists in that the steam chamber (57) is not
static and rotates joined to the rotary tube (48). Furthermore it is showed the planetary
speed reducer (2) which transmits the rotation of the rotary tube (48) to the central
post (1). The feeding tube (8) also enters by the upper of the tubs and it articulates
to the rotary tube (48), of equal diameter, through the already described rotary coupling
which comprises a support brake shoe (52) and the rotary lower (50) and upper (51).
The planetary reducer (2) is centered within the post and above of the rotary coupling
between the tubes. The driving gear (79) of the reducer is mounted in a bushing (78),
joined at the upper plate (51) and slightly adjusted slightly to the feeding tube
(8). The shafts of the other gears of the reducer, which are fixed to transmit the
torque forces, are mounted on a round support (80), fixed to the feeding tube (8)
which also serves to support the rotation of the post (1) through a bearing system
(81).
[0028] Below the rotary connection, the cylindrical steam chamber (57) is integrated to
the rotary tube (48), thus, the tube centrally crosses the chamber. The rotation of
the exhaust and the steam chamber (57) together with the rotary tube (48), allows
the continuity between the internal tube (68) of the steam chamber and the tube (38)
which feeds from this to the suction chamber (37) of the exhaust be made with out
the necessity of use a rotary seal. The power supply to the resistance (56) that heats
the water of the steam chamber is done indirectly, either through a sliding socket
connection over the copper or brass rotary rings, as it is described below, or by
means of an electric converter, whose primary is fixed and the secondary, turning
with the other components, it feeds to the electrical resistance. Other form to heat
the water stored in the chamber is by heat conduction through the walls thereof, placing
a heater close to the outside of these walls. These heating systems are not shown
in the figure.
[0029] As in the fig. 4, the curved portion, (46) and (47), of the rotary tube (48) and
the exhaust are confined within the cover (58) which in this case is separated of
the central post (1). It is observed that, within the cover, the curved portion of
the rotary tube (48) and its end (40), connected to the Venturi (39), increase their
diameter, as far as possible, to decrease the pressure losses. The output tube (36)
outstands of the plane (66) of the cover (58) directed towards the dragging zone which
is formed by the end (44) of the helical plate (4) and the core surface of the tub
(59). By the front of the exit of the exhaust (36) and the dragging zone, the cover
(58) has welded a horizontal plate (77) curved upwards (see the cutting of the AA'
section), which serves to the water jet and the dragged clothes being deviated upwards
of the tub and the rotary impulse of the water mass of water around the post be broken,
so that in the other spaces of the tub the streams being slow and the clothes not
be so much ruffled.
- The figure 6 is a mechanism which controls the paused rotation of a rotary washing system, which
uses a planetary speed reducer to transmit the rotation of the rotary tube (48) to
the central post (1). The figure only shows a zone of the central post (1), with the
rotary tube (48), the planetary speed reducer (2) at the upper and the controlling
mechanism at the bottom, with a portion of the bell-shape cover (58).
[0030] It can be seen that the mechanism firstly consists of a thick ring of rectangular
section (87) or cam ring, concentric with the rotary tube (48) and fastened by a radial
arms (49) to the inner wall of the central post (1). The upper surface of this annular
plate (87) or cam ring is divided in any appropriate number of sections which comprise,
each of them, a split portion or valley (89) followed by a slope which finishes in
a top or flat crest (88), as cam path. In each section, four in this figure, a corresponding
leg (86) with a rounded and slipped end that in whole supported and slipped over each
of the paths, by above of a second heavy ring (85). This ring is mounted on the rotary
tube (48) and lashed to this by means of a longitudinal wedge (90) fixed to the own
tube, in such a way that, with light adjustments, the ring (85) can slide along the
tube but not rotate respect to this. The rotation of the second ring (85) and, therefore,
from the rotary tube (48) is stopped when the upper face of this ring is pressed against
a stopping plate (84) adhered to a no rotary third ring (83). The third ring (83)
can be a little raised to separate the stopping surfaces and to release the rotation
of a second ring (85) and, consequently, the rotation of the rotary tube (48), of
the exhaust (2) and the post (1). Thus, the third ring has at the upper an articulated
handle to the end of a lever (91), which raises the ring to rotate in its other end
over a swivel encrusted on a bar (92) which, passing through the free space of the
exhaust (2), it is fixed to the support (80) of the reducer shafts; thus this disposition
avoid, on the other hand, the rotation of the ring (83). To stop of release the rotation
of the tube, allowing that the third ring presses over the second or separating to
these, the lever moves vertically by a valve rod (93) articulated in the middle portion
of the lever and acting by springs and any mechanic system or electromagnetic of control.
[0031] By means of the reducer and this mechanism, the paused rotary cycle of the rotary
tube (48), coordinated with the rotation of the post (1) and its helical plate, is
carried out by the driving frequency of the valve rod (93) and by the relative rotation
between the rotary tube (48) and the cam ring (87) which rotates, together with the
post, slower than the tube. During this relative rotation, the second ring (85) locate
its legs (86) upon the high cam paths and it is pressed against the plate (84) of
the third ring (83), stopping its rotation and the one of set. The stopping lasts
until that the valve rod (93) raises to the third ring a time to releases again the
rotation, which, when continuing, does that the legs of the second ring fall in the
low cam path, avoiding the stopping until that the mentioned rotation puts back them
into stopping position and the cyclic position of the output tube of the exhaust respect
to the dragging zone, must be such that allow the paused circulation of all the clothes
through the tub, with out entangle so much.
[0032] The figure 7 is, basically, similar to the rotary washing system of figure 5, except that the
system is below the tubs (7) and (14), connecting the feeding tube (8) to a passing
hole (103) at the core center of the centrifuging casing (23)). Over the passing hole
(103) is fixed vertically, as a continuation of the feeding tube (8), a short stretch
of flexible hose (102) whose upper end joins a first short and rigid tube (101), staying
these two loosely housed inside the draining tube (61) of the centrifuging turbine.
This first rigid tube (101) is introduced certain distance within a second tube (100),
joined to the core center of the internal tub (14) and which crossing this, it rises
within the tub until a height a little above of the established floating level (29)
prefixed of the same tub. This arrangement serves to, without interrupting the continuity
of the feeding duct, the second tube (100) and the tub can rotate on the first tube
(101) and, at the same time, they move with this one laterally in any direction due
to the flexibility of the hose, allowing the rotation of the floating tub around any
virtual shaft during the centrifuging.
[0033] A third tube or rotary tube (48), equivalent to the tube (48) of figure 5, is inserted
into the second tube (100) by the upper portion of this, until that a ring-shape smooth
brake shoes (99), which has each of the tubes, settled one on the other to support
the weight and rotation of the third tube overt the second one.
[0034] The aforementioned tubes are introduced one into the other with a fine adjustment,
as a pillow block, to allow the free rotation between them and to form, together with
the initial hose, the duct to feed the rotary washing system as continuation, with
equal big diameter, of the feeding tube (8).
[0035] In the figure 7 it is seen the upper end of the rotary tube (48) that finishes off
and debouch into a closed chamber (97), in form of dome or of a double wall-widen
bell, so that the tube (48), gradually opening its diameter, is connected with the
inner peak of the bell, which centrally surrounding the tube, it enlarges and unfolds
until the tub core. Over the drainage of the rotary tube (48) there is a conical appendix
(98) which, with the vertex directed downwards, serves as a deflector for the flow
which goes out by the nozzle of the tube (48) deviates 180 degrees towards the periphery
and the bottom of the double-wall bell, where the same bottom and the two walls of
the chamber (97) are extended and converge (see cutting of AA' section) in such a
way that they are molded in a circular exit (107), horizontal and tangential, which
is connected with the conical and gradual entry, of a horizontal, curved tube (40)
of big diameter tagged to the core of the bell. As well as in Figure 5, the tube (40)
is connected to the Venturi (39) of the exhaust, in such a way that this stays within
the cover(58) which is a radial extension of the bell-shape chamber and only the outlet
tube (36) of the exhaust outstands through a hole in a vertical and radial plane (66)
in which ends the cover, directing the discharge of the water jet and steam bubbles
towards the dragging zone formed by the surface (44) of the helical plate (4) and
the core of the tub (14). In front of the dragging zone is fixed to the chamber (97)
a curved plate upwards (77), with the same function described in Figure 5. The rotary
coupling of the tube (48) with the second tube (100) and the water jet discharge,
perpendicular to certain distance of the center, by the output tube (36) of the exhaust
produce a pair of forces by jet reaction which makes rotating the washing system,
as it was described. Due to the big section of the bell-shaped chamber (97), the losses
by changing the direction of the flow within them are minimal.
[0036] In order to feed to the suction (37) of the exhaust by the steam chamber (57), rotating
both with the rotary washing system, this is placed inside the central post (1) in
such a way that the same connection tube (38) of the steam is used to join the core
center of the steam chamber with the dome center of the bell-shape chamber (97) to
make rotate that. The upper end (68) of the connection tube (38) stays within the
steam chamber in order to suction this and its bottom end (104), welded to the dome,
and continues its connection until the suction (37) of the exhaust.
[0037] At the upper of the steam chamber (57) is welded a shaft (105) which moves the central
gear (79) of a planetary speed reducer (2), which transmits the rotation of the chamber
to the central post (1). In order to transmit the pair of the impelling shaft (105)
it is necessary that the shafts of the others intermediate gears (96) be fixedly supported
respect to the system; but, on the other hand, all the rotary washing system must
be able to move in any lateral direction according the internal tub moves while centrifuging.
Over the reducer (2), is placed a round plate (80) which supports such shafts, and
it is joined by above, to other upper plate (95) fixed to the structure (94) of the
washing machine by a flexible tube (106) which supports the twist, in order to allow,
with out rotating, the lateral displacement of the support plate together with the
rotating system. In addition, the plate (80) registers the rotating of the upper end
of the impelling shaft (105) in a central bushing and, at its periphery, the rotation
of the central post (1). The power supply which in this figure appears within the
flexible tube (106), to the resistance (56) of the steam chamber is detailed in Figure
8.
[0038] The figure 8 is an amplification of the upper portion of the central post (1) of figure 7 and
shows two variants more of the system which allows the lateral displacement of the
support of the shafts of the speed reducer (2). As in the previous figure, these variants
have a round plate (80) which supports the shafts of the gears (96) of the reducer
and also it registers the rotation of the impelling shaft (105) and of the central
post (1).
[0039] Before continuing, it is taken advantage of Figure 8 to describe the power supply
to the resistance (56) of the steam chamber (57) (Fig. 7). The support plate (80)
extends upward in a box (108) within which are mounted two rings of copper or brass
(109), electrically isolated at the end of the driving shaft (105) joined to the steam
chamber. Each ring (109) is connected to a terminal of the electrical resistance (56)
by wires, sealed within an axial hole (not illustrated) in the same driving shaft
(105) until the resistance (see Fig. 7). The electrical energy is fed by brushes (110)
which slide on the rings (109) during the rotation.
[0040] Over the box (108) of the support (80) of the shafts, it is centrally fixed a horizontal
bushing (111) inside the one that freely slides a round bar (114), in whose ends are
welded, perpendicularly to them and centered, other round bars (112). Each of these
two bars freely moves in their turn within set bushings (113), one on each side of
the bar, which are joined to a plate (95), fixed to the structure or lid (94) of the
washing machine. In summary, the mechanism consists of fixing the box (108) of the
support (80) to a first runner, which allows to move it along a shaft, and this first
runner is fixed to another similar runner which moves in perpendicular sense to the
first one, therefore the device, combining both perpendicular displacements, allows
to the support moves in any lateral sense, but not rotate.
[0041] At the right bottom of Figure 8 shows one third variant of the system that holds
the supported plate (80) so that this can move laterally, combining a linear movement
with another angular. Over the support box (108), a horizontal round bar (114) is
introduced within a bushing (111) that can slide freely through the bar and articulated
rotate to a vertical bolt (118) fixed at center of the box; furthermore, an end of
the bar can rotate on another bushing (116) articulated to another vertical bolt (115)
fixed to the structure (94) of the washing machine. To avoid the tendency to rotate
of the plate (80) and its box (108), are placed speed bumps (117) on the box (108),
so that when beginning to rotate the plate these speed bumps block the rotation with
the bar side (114).
- The Figure 9 is a washing machine equal than Fig. 7, except that the steam chamber (57) is fixed
and can be placed outside the rotary washing system which remains centered with the
geometric shaft of the washing machine, without moving with the internal tub (14)
during the centrifuging cycle.
[0042] As in the figure 7, the feeding tube (8) is connected to the central passing hole
(103) of the core of the centrifuging casing (23) and on this hole it is fixed directly,
onto a brake shoe or base ring (120) of smooth surface, a first short tube (101) as
continuation of the feeding tube (8). In this case, the short tube (101) is introduced,
with pillow block fine adjustment within the third rotary tube (48) described in figure
7, in such a way that this can freely rotate over that supporting its brake shoe or
bottom smooth ring (99) over the base ring (120), to support the rotation and the
vertical boost of the washing system. As passageway so that the rotary tube (48) comes
in the internal tub (14) and ends within this in the bell-shape chamber (97), a second
tube (100) raises in the core center of the internal tub to a height greater than
the flotation level (29), to avoid the entrance of the water to the tub during the
same flotation. The second tube (100), opposite to the same tube of Fig. 7, does not
fit to the other tubes and it must be of such diameter that it keeps enough clearance
between it and the rotary tube (48) and equal clearance with the inner wall (119)
of the bell-shape chamber (97), so that the tub (14) and the same second tube (100)
can laterally move during the centrifuging, with out collide with the chamber or with
the rotary tube.
[0043] The conduction of the steam from the fixed steam chamber (57) to the suction chamber
(37) of the exhaust is made firstly by means of a thin tube (68), which connects the
upper zone of the steam chamber with the inner of a closed box (108) within the central
post (1). This box serves for the passing of the steam to a second vertical thin tube
(38), whose upper end comes in, with smooth adjustment, into a centered bushing at
the box core. Since, having its bottom end welded to the dome centre of the bell-shaped
chamber (97); the tube (38) must rotate over the bushing, at the entrance of the tube
(38) a rotary seal is placed, to avoid leaks. The connection of the steam is completed
through another thin tube or hose connected between the lower end (104) of the second
thin tube and the suction chamber (37) of the exhaust. In the second tube (38) is
mounted the input gear (79) of the planetary reducer (2) and the support (80) of the
shafts thereof, integrated to the passing box (108), it is fixed to the lid (94) or
the machine structure. In such a way the thin tube (38), in addition to drive the
steam to the suction of the exhaust, it serves as impelling shaft of the speed reducer
and as shaft which support the upper of the rotary washing system, which rotates centered
and does not require of the mechanisms described in Fig.8.
[0044] The figure 9 also shows another system to fit the flotation level (29) of the tub
before the centrifuging. The system consists of a closed container (126) which has
a volume equal than the water volume which is between the two tubs and the flotation
level (29), excluding the free volume within the centrifuging casing (23). Below the
closed container (126) there is a small draining pump (62) which connects its input
or suction (122) to the core of the main tub (7) through a valve (121) and its output
or discharge (124) to the core of the closed container (126) through another valve
(125). Additionally to this first connection, it is added another pair of tubes with
their control valves (123) which connect the suction and the discharge of the pump,
by exchanging the initial connection between these with the tub and the closed container,
respectively. At the top, the container (126) has a tube (64), with its control valve
(127), which connects it to the output (65) of the main tub (7) on the flotation level
(29); moreover also having a waste-pipe (63) to drain it to a high level.
[0045] After the washing or rinsing cycles and keeping closed the valves (123) the draining
pump (62) is started with the valves of the first connection, (121) and (125) opened
in order to evacuate the water of the tubs until the level of the core of the main
tub (7), transferring it to the closed container (126); in such a way that the excess
of water which passes over the volume of the container is evacuated by the waste-pipe
(63)to the general drainage and only remains, therefore, in the container (126) the
necessary volume to fill again the space between the tubs at the flotation level.
When the level of the extracted water becomes below of the core of the internal tub
(14), the retainer valves (27) of the core of this open and allow the exit of the
remaining water thereof. After emptying the tubs, the valves (121) and (125) of the
initial connection are closed and are opened the two valves (123) of the second connection,
so that the water flow is inverted between the container and the tub, in such a way
that all the water stored in the container (126) is retaken to the main tub, so that
the water level between the tubs reaches the prefixed flotation level. When the water,
which is returning to the main tub (7), comes to the core level of the internal tub
(14) the retainer valves of this one are close and avoid that the entrance of water
to the inner thereof, thus, this tub stays floating to start the centrifuging. With
the opened valve (127), the excess of water from the squeezed clothes, which comes
out of the internal tub, is drained by output tube (64) at the side of the main tub
towards the closed container (126), keeping the flotation level (29).
[0046] Fig. 10 is amplification, for better clarity, just of the bottom of the tub (7) and the tub
(14) with their central tube (100) and the balancing chamber (28), of Figs. 7 or 9.
This chamber, at the side of the internal tube as variant of the chamber of Figure
1, not only includes the first annular portion (28) of the side of the internal tub,
but also it continues in a second portion or cylindrical cavity (129) below of the
basis of this tub, in such a way of double core crossing by the central tube (100).
The annular portion (28) of the chamber is divided by vertical plates (128) in opened
cells set communicated below with the second portion of the chamber (129). These vertical
cells are of two types, both alternately distributed from the side of the tub.
[0047] Each cell (133) of the first type is divided in two portions by means of a horizontal
plate (130). The upper portion is separated of the rest of the chamber by the plate,
forming a comportment (131) which has a series of holes (10) in its inner wall and
another series of holes (132) by above of the flotation level (29), in order to not
affect this one in its outer wall; thus, the first type of cells serves to evacuate
from the internal tub (14) the recirculating water flow. The bottom of these first
cells (133) has the same function as the second type of cells. Within the compartments
(131) can be placed filters.
[0048] The cells of the second type (134) lack of holes and they are directly communicated
to the double core of the tub (129), which stores, when the tub is not rotating, the
fluid and heavy material which serve as counterweight to balance. If the clothes are
not distributed when the tube is rotating the virtual rotary shaft, which passes through
the center of gravity, it will move at certain distance of the geometrical shaft of
the tub towards the overweight is, in such a way that the cells diametrically opposed
to the counterweight keep with a greater rotation radio that the cells closed to the
overweight, provoking the tendency by the centrifuging force, that the counterweight
flow enters in greater amount into the opposed cells than the closed to the overweight..
To increase the balance of the tub by this distribution of the flow and however that,
for the same reason, the virtual shaft moves to coincide with the geometrical shaft,
the flow trapped in each of the second cells (134) could not be redistributed in the
whole annular chamber as in Figure 1, since the separating plates (128) of the plates
impede it to do it, which allows to continue keeping the initial balance.
- The figure 11 only shows only the core area of the main tub (7) and internal tub (14) of Figure
10, making greater vertical scale than the horizontal, in order to describe more clearly
a mechanism which is added to the balancing chamber of Figure 10 to improve the performance
of this. This mechanism is housed at the second horizontal cylindrical portion (129),
centrally crossed by the tube (100) of the chamber (28) and it works obstructing the
passing of the balancing fluid towards the cell of the second type (134) from the
overweight side by compensating and allows this passing towards the cells of the opposite
side. Inside the cylindrical cavity (129) of the balancing chamber, there is a horizontal
bar (135) with a ring (138) at its center slightly adjusted to the diameter of the
support tube (100) which serves as shaft so that the bar rotates respect to the geometrical
center of the tub. At a side of the bar (135) is mounted a small counterweight (136)
which can slide over the bar and whose sliding towards the end of this one is limited
by a spring (137), which works to compression with little force. Near the entrance
of the cells, the other end of the bar is joined to the center of a light and vertical
plate (139), which has a width, a curvature and a length such that obstructs the passing
of the fluid towards some cells.
[0049] If the weight of the clothes is asymmetrically distributed when the tub starts to
rotate, the geometrical shaft of the tub or the passing tube (100) and, therefore,
the bar (135)) together with its central ring (138) will rotate around the virtual
rotary shaft which is displaced to certain distance from the geometrical shaft; by
the above, the centrifugal force applied to the counterweight (136) will cause that
the bar rotated on its ring (138) until that the counterweight (136) until the counterweight
stays diametrically opposed to the virtual shaft or to the clothes counterweight,
compressing the spring (137) to go over the end of the bar. In this position the obstruction
plate (139) covers the entrance of the balancing fluid to the cells of the second
type (134) of the side where the overweight is, until the fluid which goes into the
opposite cells compensates the weight undistributed. As the weight is balanced within
the tub, the virtual rotary shaft approaches to the geometrical shaft and the centrifugal
force on the counterweight (136) is annulled to coincide both shafts; at the same
time, the counterweight (136) stops to compress the spring (137) and it is passed,
pushed by this, towards the center to its initial position; this movements provokes,
by the conservation of the annular moment, that the counterweight (136)the bar (135)
and the obstruction plate (139) tend to increase their rotary speed rotating faster
than the tub, so that the position, with respect to the cells, of the bar (135) and
the plate (139) is indifferent and the rest of the balancing fluid is uniformly distributed
in them.
[0050] The Fig. 12 is a mechanism which supports to the internal tub during the centrifuging, coincide
or not its virtual rotary shaft of rotation with its geometric shaft. It is considered
the speed of any point of the tub is equal to the speed of the point respect to the
geometrical shaft of the tub plus the speed of this shaft respect to the virtual shaft.
[0051] In this figure only is showed the core of the tubs, main (7) and inner (14), and
the new mechanism which supports to the internal tub. The first portion of the mechanism
consisting of a platform (146), centered under the internal tub (14), which has a
central hole which is loosely cross over, by a guiding tube (145) which is centrally
joined to the core of the tub. The rotation and the weight of the internal tub are
supported by a circular tier or series, concentric with the tub, of vertical wheels
(143) with shafts fixed to the platform and directed in a radial form to the center
of the tub. Other series of horizontal wheels (144), with their vertical shafts also
fixed to the platform, are distributed around the periphery of the platform hole,
in such a way that the wheels, supporting their rotation on the surface of the guiding
tubes (145), keep and guide the concentric rotation of the internal tub (14) respect
to its geometrical shaft and to the platform (146). The speed of any point of the
tub due to this rotation, concentric to the geometric shaft of the tub, constitutes
the first component of the absolute speed of the same point.
[0052] The second portion of the mechanism allows that the platform moves freely in any
lateral direction; for this a series of supports is placed under the platform to sustain
it. Each support consists of a horizontal bushing (147) with a round bar (141) of
certain length within it, over which the bushing slides freely as slide valve; the
bushing can transversely rotate to its geometric shaft on a vertical pivot (148) fixed
to the platform below this one, at the same time that the bar (141) can move horizontally
and angularly, rotating over one of its ends welded to another bushing articulated
to a vertical pivot (142) anchored this on a round protuberance which outstands from
the core of the main tub (7). So that each of the bars (141) did not support in cantilever
the weight of the tub which transmits to it its sliding bushing (147), at the other
end of each bar, opposed to the rotation, it is mounted a vertical wheel (140) with
its collinear shaft to the bar and from such diameter which rolls tracing a circle
supported over the core of the main tub (7), when the bar moves angularly. The combination
of the linear movement of the sliding bushing (147) on the bar (141) and the angular
displacement of these over one of their ends, it gives freedom to the platform (146)
to displace in its horizontal plane in any lateral direction, without rotating in
any lateral direction, in similar for to the described system at the bottom of Fig.
8.
[0053] Another form to support the lateral displacement of the platform8146) consists holding
this to a first sliding system which moves in certain horizontal direction, being
this first system fastened in its turn to a second sliding system fixed to the main
tub, which moves also horizontally, in a perpendicular direction to the first system,
in similar form to the system illustrated at the upper of Fig. 8.
[0054] The second portion of the mechanism described in the last two paragraphs, in any
of its two versions, allows that the platform (146) supporting to the internal tub,
and carried or driven by this same, moves horizontally, tracing a circle equal than
the circle that trace the geometrical shaft of the tub around any virtual shaft on
which rotates the tub. This movement of the platform provides to any point of the
tub the second component of the total speed, with which such point moves respect to
the virtual shaft over which the tub rotate.
[0055] The figure 13 is the same washing machine than in Fig. 7, except that the mechanism of Figure 12
is added to support the rotation of the internal tub (14). In addition, are used two
centrifugal pumps coupled to the same submersible motor (150) , which are within the
centrifuging chamber (23) supported by a plate (152) which hangs from the platform
(146) of the same supporting mechanism from Figure 12.
[0056] One of the pumps (149) directly feeds the jets of the nozzles (17) which impel the
special turbine Pelton, whose box (25) is joined to the guiding tube (145) from the
core of the tub. The feeding tube (8) connected without a valve to the discharge of
another pump (18) is inserted directly, with smooth adjustment into the passing tube
(100) of the tub over which rotates the tube (48) of the same rotary washing system
from Figure 7. The suctions (19) of both pumps stay directly submerged within the
centrifuging chamber (23), where continuously re- circulate the water to establish
the two closed pumping circuits. The two centrifugal pumps operate with different
rotary direction, with the purpose to operate either the rotary washing or centrifuging
system; it is enough to change the rotary direction of the engine or motor in its
feeding wires (151), sealed and flexible, activating the performance of a system and
deactivating from another one, without the need of use control valves. The engine
or motor with two pumps of opposite rotation can be used in the other cases described
here.
[0057] The Figure 14 is a device for disintegrating the threads that the clothes loosed and to avoid that
they obstruct the performance of the pump (18). The device is mounted within a large
diameter tube (159), interposed in the suction tube (19) through a conical tube (155).
The device consists of a rotating blade (157) of several sheets, mounted transversely
in an extension (156) of the driving shaft of the pump, cutting the threads which
the water carries against other fixed blade (153), also of several sheets by adjusting
the pressure between them with the spring (158) at the end of the shaft. Rotating
blades (157) also pressed against a plaque (154) below with multiple perforations
that retain some threads to be crushed by the blades against the same plate.
[0058] The Figure 15 shows a washing machine of two horizontal tubs and front-loading, similar to the
common of this type, in which are applied the new concepts described in the previous
figures. As in those figures, the washing machine has a main tub (7) which in this
case, is a drum placed horizontally, with a circular, chamfer or conical opening (161)
on its front face and within which is placed, centrally, another rotary horizontal
drum or internal drum (14). This last drum has multiple perforations (10) and a series
of parallel blades (5) internal welded along its side, furthermore a circular opening
(168) chamfered on its front face, to introduce the clothing. To contain the water
inside the drums, the front opening (161) of the main drum (7) is closed hermetically
by a conical periphery cover lid (162) with a sealed wrapping
[0059] During the washing or centrifuging, the internal drum (14) should be adapted to rotate
within the main drum (7); for this, the main drum (7) has, in the back side and housed
towards its inner, a first wide and short tube (174) joined by its back end to the
core center of the drum, with free passing to the inner of this one; in such a way
that this first wide tube remains, with a smooth adjustment, into a second wide tube
(175) with its inner end externally joined, to the core center of the inner drum (14);
thus the rotation of the internal drum (14) is supported on the rotation of the second
wide tube (175), as a pillow block, over the first wide tube (174), as a support shaft.
[0060] On the other hand, the rotation of the inner drum (14) at its front end is supported
on a wheel (167), with conical periphery, which fits in the round opening (168) chamfered
from the drum and rotates with this. The shaft (163) of the hub (165) of this wheel
(167) rotates supported by a bearing box (164) sealed and joined to the center of
the lid (162) of the main drum (7), so that this lid (162), pulls with oneself to
the supporting wheel (167) to close or to open, for putting or to removing the clothes
. To have an adjustment pressure of the linkage between the wheel (167) and the internal
drum (14), the wheel hub (165) internally has a compression spring (166) which supported
at the inner end of the shaft (163) pushes to the cube so that the wheel be pressed
over the opening of the drum.
[0061] Also in Fig. 15 the washing machine works with a pumping closed-circuit which feeds
of power to the washing or centrifuging connecting the pump discharge (18) to each
of these two systems and their suction (19) to the bottom side of the main drum (7).
Due to during the centrifuging, as it will be seen in the figure below, the drums
move together with their connection pipes to the pump (18), in these pipes are interposed
some hoses (102) with enough flexibility to absorb such movements.
[0062] The washing is made, as in prior cases, by a special fixed exhaust fed by a tube
(8), with control valve (13), connected to the discharge of the pump (18) and with
the suction of the exhaust connected to a chamber (57) steam generator, also fixed.
The back and central connector, from the water flow for the washing is made using
a conical intermediate amplification (172), with a deflector nucleus (173) also conical
in its center, to connect the feeding tube (8) with the back end of the first wide
tube (174) of the mean drum, in such a way that this tube introduces the flow inside
the inner drum, passing through the wide tube (175) of this. The wide feeding tube
(174) is connected and ends centrally, within the inner drum, on the basis of a cylindrical
horizontal box (97) which serves to direct the flow towards the input of the exhaust;
in such a way that the big area of the section from these two components decreases
the speed of the flow, and thus, the friction losses by the changes in its direction.
So that the water flow acquires a rotary impulse to enter in the cylindrical box (97),
it is placed within the first wide tube (174), along to this and until the core of
the cylindrical box, a duct or helical plate (160) which gives this movement to the
flow. The flow which is entering to the cylindrical box with such movement is directed,
through a volute (176) within the box, towards an output tangential tube (40) in the
box periphery. The output tube (40) ends in the Venturi (39) of the exhaust, which
directs its exit downwards and the most tangentially possible over the blades (5)
from the bottom sides of the drum, in such a way that the water jet and the bubbles,
colliding against the blades, impulse the rotation of the inner drum to cheat with
the same blades to the clothes, in the sine from which cavitate the bubbles. The connection
between the steam chamber (57) and the suction chamber (37) of the exhaust is made
by a thin tube (38) which enters, by the wall of the first wide tube (174), towards
the cylindrical box and the exhaust within this.
[0063] In order to make the wringing by centrifuging, in the second wide tube (175) is mounted
a common Pelton turbine (170), which is impelled by water jets which collides over
the buckets (24) and they are launched by nozzles (17), with control valve (16), connected
to the discharge of the pump (18) therefore, thus, the turbine drag in its rotation
to the inner drum holding back the wet clothes for wringing. In the prior face of
the buckets is perforated a small hole (169) in which finish a radial thin duct (171)
which is until the inner surface of the second wide tube (175), with the purpose that
the rotation of this tube be lubricated with a small portion of the same water which
launch the nozzles over the buckets.
- The Fig. 16 is a variant very similar to the horizontal washing machine of the Figure 15 and,
as in this figure; the connector of the feeding is the central back part of the mean
drum (7). This case the feeding tube (8) is directly connected with the Venturi (39),
in such a way that this, the output tube of reduced diameter (36) and the suction
chamber (37), fed by the fixed steam chamber (57) through the tube (38), which compose
the special exhaust, are housed securely within the wide tube (174) joined to the
center of the mean tube (7) and which serves as shaft of the inner drum (14) and it
curves downwards and the steam bubbles towards the bottom side of the drum. The end
of the output tube (36) is covered with a disc (58) close to the core of the inner
drum and of rounded surface to avoid that the clothes be hooked with such end.
[0064] In this case, the closed pumping circuits for the washing and for the wringing are
separated, so that the hydraulic circuit which feeds the exhaust is fed by a centrifuge
pump (18) which works with a rotary sense contrary to the centrifuge pump (149) of
the wringing circuit by centrifuging, both being impelled by a same motor with the
interchanging rotation to activate one or another pump. This double pumping circuit
has the purpose of to alternately turn each circuit, in such a way that to operate
the wringing pump (149), this launch a water jet, through of its tube and the discharge
nozzle (17), over the buckets (24) of the Pelton turbine (170) joined to the inner
drum to rotate this a little bit and to make the shoveled of the clothes by means
of the inner blades (5) of the drum. Then the rotation of the motor is changed to
turn the pump (18) function which feeds and activates the washing action of the exhaust,
repeating adequately of the two cycles slowly.
- The figure 17 shows the system which allows to the inner drum (14) of the Figure 15
or 16 rotate, during the centrifuging, over the virtual shaft which passes by its
center of gravity. This system is similar to the described on Figure 12 and is based
also in a support, equivalent to the support (146) of this Figure, which support to
the tub or inner drum (14) rotating over its own geometrical shaft, while the support
and the drum move laterally around the virtual rotation shaft. In this case, the same
mean drum (7) has the function of the mentioned support since the inner drum rotates
centrally inside the mean drum. The system which holds the mean drum and allows it
to move laterally, in any direction, consists of 4 ears (177) welded symmetrically
to the sides of the man drum (7) in four points, two in front and two at the back.
En each ear is articulated, by a horizontal pivot (148), a vertical bushing (147)
which can rotate transversally to its geometrical shaft over such pivot. Within the
bushing it moves, in a runner form, a vertical rounded bar (141) whose upper end articulates
a pivot (142) which allows to the bar oscillate in angular form, as pendulum, over
such end in a perpendicular plane to the shaft of the drums. In the bottom end of
each bar (141) is fixed a spring (178) which supports the weight of the drums supporting
the bushings (147) over the upper ends of the springs.
[0065] To avoid that the forces of the vertical movement of all the prior supports system
of the drums be transmitted to the structure (94) of the washing machine in vibration
form, this system in its turn is fastened to another system which consist on fixing
respectively the two pivots (142) of the fore oscillating bars (141), and equally
in the two pivots of the rear end, to each one of the ends of an horizontal bar (179)
in whose middle part is raised a vertical shoot (1839 are articulated, in rotary form,
an end of each of the other bars (184) which are opposite, each one towards a side
of the shoot, and sloping downwards with certain angle, as normal position. The other
end of each of these two bars, also sloping, is articulated in same rotary form, to
a corresponding second horizontal rounded pushing bar (182) which runs within a bushing
(180) fixed to the structure (94) of the washing machine. The driving in opposite
sense of these last two horizontal pushing bars (182) is limited by springs (181).
Thus, the motion vertical force upwards and downwards of the horizontal bar (179)
is projected by the two sloping bars (184) in two horizontal forces and opposite over
the bars (182) and the pushing springs (181) to both sides of the shoot; moreover
of the little vertical projection of this force just produces pairs o torsion efforts
contrary in each fixed bushing (180), in such a way that the forces over the two springs
and the torsion pairs over the two opposite bushings to those from the other side,
therefore, the reactions over the structure of the washing machine are equal and opposite,
therefore, the vertical motion force is transformed in inner efforts over the structure,
annulling as vibration producers.
[0066] To decrease the movement of the virtual shaft of rotation respect to the geometrical
shaft of the drum, as in Figure 1, annular balancing chambers (28) are placed, surrounding
each end of the inner drum (14).
[0067] The Figure 18 is a variable of the Figure 12 to avoid the vibration in the centrifuging,
similar to the system on Figure 17, but applied to a vertical washing machine, in
such a way that the mean tub can be move laterally to be supported by a special supports
system, while the internal tub rotates over its geometrical shaft within the mean.
The washing system is the same of Figure 7, except that the feeding tube (8) of the
exhaust enters directly into the mean tub (7) fixed to this and adjusted to the inner
of the central passing tube (100) of the internal tub (14), in such a way that, furthermore,
the tube can rotate over its same passing tube (100) coupled to the Pelton-type turbine
(25) and registering its rotation in a bushing (185) that the mean tub (7) has in
its center. Although it is not required, is convenient that the tub floats so that
the weight thereof over the bushing is less.
[0068] The mechanism which during the centrifuging allows to the mean tub to move in any
lateral direction in a series of supports which support to the tub below and around
this, similar to the wheels which aligns automatically in the direction of the displacement
towards any side. In this case each support comprises a flat horizontal bar (147)
which in one of its ends is articulated a bearing of vertical shaft or pivot (148)
fixed to the core of the tub, which allows that the bar oscillates in a horizontal
plane over such end. The flat bar, following the movement of the tub, moves lineally
in any of both senses supported over the upper periphery of a vertical wheel (186)
whose mounting (141) can rotate horizontally over other bearing of vertical shaft
(142), so that the wheel can align in any moment with the direction of the bar. Below
of the box which support to this last bearing (142) is welded a guide vertical bar
(188) which runs within a support bushing (187) fixed to the structure (94) of the
washing machine. Between the bearing box (142) and this supporting bushing (187) is
placed a spring (178) which works to compression, as a shock absorber to support the
weight of the set in its displacement around of the virtual rotating shaft, the flat
bar (174) must be of the enough length to allow the desirable displacement of the
mean tub (7) and so that the vertical wheel (186) always keeps a minimal horizontal
distance respect to the pivot or bearing (148) of the bar, with the purpose of that
exist a pair which induces the aligning of the bar with the direction of the displacement
of the tub in each moment.
[0069] On the other hand, the connection pipes, (8) (17) and (19), between the tubs and
the pumps (18) (149), have, as in Figure 17, intercalated a stretches of flexible
hoses (102) to allow the lateral movement of the connector tubes together with the
mean tub (7) respect to the pumps.
[0070] The Figure 19 is a variant of the supports in Figure 18, therefore, also this new
supporting system (189) of the mean tub (7) serves so that this can displace laterally
in any direction, while the internal tub (14) rotates over the shaft (194), which
registers its rotation in the central bushing (185) of the mean tub and it is impelled
by the afore described turbine system (25).
[0071] The new system consists in a supporting series (189) which support to the mean tub
(7) distributed around its upper periphery. Basically each support consists in a horizontal
crosshead of two bars or shaft (191) joined in its center to 90°, in such a way that
one of the shafts rotates in its ends over the lateral of an upper inverted u-shape
plate (190) welded to the upper portion (187) of the structure of the washing machine
through the fixed bar (193). The other crossed shaft rotates also over the lateral
of the other bottom inverted U-shape plate (192) from which hangs the upper end of
a second bar (141) which passes comfortably through a horizontal hole practiced in
a ear or plate (177) welded to the side of the mean tub (7), so that a spring to compression
(178), fixed to the bottom end of the bar, supported below of the hole of the ear
to this and to the weight of the tub. Thus, the combination of the free oscillation
or angular rotation in a plane, over one of the shafts of the crosshead (191), of
the bottom "U" plate (192) together with the bar (141) and the oscillation or angular
rotation of these over other shaft of the crosshead, in the other perpendicular plane
to the first one, allows that the bar (141) can oscillate angularly in any direction
respect to the supporting bar (193) of the crosshead, supporting to the tub in any
lateral displacement limited of this. This system is similar, with a different use,
to a universal transmission meeting of rotation between two shafts no aligned as are
the bars (14) and (193).
[0072] A variant which is not showed in the figure consists in welding the upper end of
the bar (141) which supports to the tub, to a settled sphere over a spherical surface
of the structure (187), as a toggle joint articulation which allows it to oscillate
in any direction where the tube displaces.
[0073] The Figure 20 is a vertical washing machine, as in Figure 3, the exhaust and its
steam chamber (57) are fixed within the central post, and the input of the feeding
tube (8) is by the upper portion of the post. Furthermore, the supporting system (189)
of the mean tub of the Figure 19, is used, so that the internal tub (14) can be centered
within to that rotating over its geometrical shaft (194) within a central bushing
(185); thanks to this and to the stretches of flexible hose (102), the connectors
of the pipes (8), (17) and (19) can be fixed to the mean tub, in such a way that the
washing machine can use the rotary washing system describe as follows.
[0074] In Figure 20, the feeding tube (8), fixed to the mean tub (7), penetrates deeply
by above within of the central post (1), fixed in its turn to the feeding tube, wherein
it is connected with the Venturi (39) of the exhaust, so that the output tube (36)
of this, stays as near as possible to the core of the internal tub (14). Through a
rotary coupling, with its supporting brake shoe (52) and rotary plate (50) as it was
described, the output tube (36) of the exhaust is articulated with a rotary tube (48)
which is short, of the same diameter and this is folded a few grades respect to the
vertical. The possibility that the rotary tube (489 be the shortest possible and that
its folding be small, allows to have losses by minimal friction on this, in comparison
to the same tube of the Figure 3. The suction of the exhaust is fed directly, through
the tube (38), by the steam chamber (57) and the electrical resistance within this
is equally fed directly.
[0075] The central post (19 fixed has two helical plates (4) separated 180° one from the
another one and, in the other hand, the core (45) of the internal tub (14) is rounded
from the center to the periphery, as a middle toroid curve, in such a way that the
core center raises a conical elevation (197) close to the end of the rotary tube (48);
in such a way that, dragging areas are formed between the surface (44) of the endings
of the helical plates (4) and the curved surface (45) of the core of the internal
tub (14). The output of the tube (48) stays tangential to the curvature of the peak
of the elevation (197) and placed between this curvature and a small conical deflector
(196) fastened around of the bottom end of the central post (1). Thus, the water jet
and the bubbles discharged by the rotary tube (48) drag the clothes which are in such
dragging areas, directing towards the periphery of the tub wherein the current and
the clothes, guided by the curvature of the tub core, raise by the side of the tubs
until the upper portion of these, to later retake towards the core by the center of
the same tubs guided by the helical plates (4) again towards the dragging areas, to
be impelled repeatedly by the jet which gets out of the exhaust.
[0076] The system consists firstly of a small motor (199), of slow speed, mounted vertically
over a plate (198) within the central post (1). The shaft of this motor is coupled
through a small pinion engage (2009 with the periphery in form of engage of the plate
(50) of the rotary coupling of the tubes, in such a way that the plate also functions
as engage impels to make rotating the rotary tube.
[0077] The Figure 21 is equal than Figure 20, except that the connector of the feeding tube
is made by the bottom part of the tubs. The feeding tub (8) is introduced below of
the central part of the box (37) and the output tube (36) of the special exhaust;
they stay housed within a tube (100) whose upper end is welded to the core center
of the internal tub (14), furthermore to be joined to the turbine Pelton (25). This
tube (100), furthermore to be the passing duct of the exhaust to the internal tub,
also serves as the rotation shaft of this and from the turbine over the central bushing
(185) of the mean tub, therefore its external diameter is adjusted to such bushing
. In reason that the exhaust is fixed, the chamber which generates steam (57) also
is fixed and it feed of steam to the exhaust directly by the tube (38).
[0078] To discharge the jet of the exhaust within the internal tub, the rotary tube (48)
is coupled, as it was described above, to the output tube (36) of the exhaust, in
such a way that the end of the rotary tube outstands a little of the core of the internal
tub by the passing tub and it is curved the necessary to discharge radially the jet
towards the periphery of the tub, thus, the jet impels the clothes which is in the
dragging zone, comprised between the core (45) of the tub and the helical plate (44),
towards the periphery and upwards of the tub. The length and the curved finish of
the rotary tube (48) as small as possible to decrease the pressure losses thereof,
therefore it is convenient that the exhaust enters within the shaft or passing tube
(100), the most as high as possible.
[0079] The rotary washing system is complete making to rotate in small pauses to the internal
tub (14) together with the central post (1) and its helical plates (4), impelled by
the turbine Pelton; for this, the bottom end of the post is joined to the core of
the tub through a thin legs (202) in order to allow the passing of the jet which launches
the rotary tube (48). Within the central post (1) is a cylindrical box (80), fastened
centrally to the structure (94) of the mean tub (7), wherein is housed a motor with
speed reducer (199) which, by its centered shaft (201) joined to the rotary tube (48),
makes rotating slowly to this so that the jet which discharges radially goes running
all the periphery of the tub. In such a way, during the washing cycle, can be alternated
the performing of the washing pump (18) with that from the centrifuging pump (149)
so that this activates the rotation of the Pelton turbine intermittently, in such
a way that the slow rotation of the helical plates combine with the rotation of the
rotary tube (48) to facilitate the circulation of the clothes.
[0080] The bottom of the Figure 21 shows with the number (195) the same zone marked with
the pointed circle in the above figure, to show that can be added, as in Figure 5
and 7, a planetary reducer (2) between the central post (1) and the shaft (201) which
move to the rotary tube, so that the post transmits its rotation to the rotary tube,
without the necessity of use a motor with the reducer (199) to make rotating the tube.
[0081] It is evident that the method of Figure 21 to make rotating the central post together
with the internal tub, joined centrally to the core of this through two or three legs,
can be applied equally to the system of Figure 20, also activating the centrifuging
circuit alternately and in short pauses during the washing cycle.
[0082] The figure 22 represents an industrial washing machine for big quantities of clothes,
which uses the recirculating pump principle and the discharge produced by a special
exhaust (as the described in Figure 2), the steam bubbles to low pressure which implode
on the water and clothes sine, as it was described in above figures.
[0083] In this Figure 22 is observed that the washing tub (7) of this new industrial washing
machine consists in a waterway as a closed rectangular path, of enough length and
with both ends rounded to make easy the transit of the water and the clothes through
these. A special exhausts series as those in Figure 2 comprised each by a Ventury
(39), a discharge tube (36) without diffuser and a steam suction chamber (37) fed
by the tube (38) from a steam generator or closed container (57) with heated water
by a heater (56), they discharge water jets and steam bubbles to low pressure within
the waterway. These exhausts are placed in such manner that along the waterway which
impelled the water and the clothes within the waterway in a closed path around this,
allowing the cleaning action of the cavitation of the bubbles over the clothes.
[0084] Each venture of the special exhaust series (19) is fed by the discharge tube (8)
of a pumping system in closed circuit whose suction tube (19) of the pump (18) is
connected to the waterway core through a filter (203). Along the inner sides of the
waterway is placed a sloping- blades series (204) so that this provoke the shoveled
of the clothes in order to be changing the relative position of this within the tub.
[0085] The Figure 23, as continuation of Figure 22, is the wringing system by rollers and
rinsing of the washed clothes in the washing machine of Figure 22. This system consists
firstly in a perforated carrier band (207) placed above the straight portion of the
waterway which form the washing tub (7); such band is formed by two stretches o portions,
so that the structure (205) between the two guide rollers (206) from the initial stretch
of the band can be knocked down angularly rotating downwards and the other portion
stays horizontal by above of the tub. Finishing the washing In the tub (7) from Figure
21, the structure (205) of the initial portion of the band, rotating angularly, is
introduced slow and gradually in slopping form within the tub (7) until the core,
while the water continues rotating an the clothes thereof. The perforations of the
carrier band (207) allow that the water continues circulating while the band retains
the clothes and raises them to the final stretch and horizontal of the band which
carries until its end where it launches them over the other bottom band (208) which
take them to introduce between the same band, supported over the guide roller (210),
and other wringing roller (209) pressured over the band, to wring the clothes by pressure.
The wringed clothes between the band (208) or the roller (210) and the roller (210)
is poured within the other tub (211), similar to that of washing, in which is rinsed
the clothes by the re-circulating pumping of the water which comprises the pump (18),
the suction (19) and the discharge (8) with the nozzle (36).
[0086] The Figure 24 is other version on the industrial washing machine which uses the same
washing and centrifuging systems above described to make its work. The mean tub (7)
is formed by a closed waterway in circle of enough size, in such a way that the inner
wall of the waterway forms a great diameter central cylinder (219) for the easy circulation
of the clothes around thereof. The internal tub (14), as in the above figures, serves
to centrifuging the clothes, has equal form than the mean (7) and it is housed within
this with certain separation between them. For the centrifuging cycle, at the upper
of the cylindrical body (219) is fixed centrally a vertical motor (218) whose shaft,
directed upwards, transmits its rotation to the internal tub (14) by a coupling (215)
which fasts, by an arms (216), to the upper portion of the inner wall of the internal
tub. On the other hand, the mean tub (7) is supported, around its upper periphery,
by a supports series (189) equal to those from Figure 19, which allow it to displace
in any lateral direction, while the internal tub rotates, over its geometrical shaft,
impelled by the vertical motor (218), as it was described. To allow the free displacement
of the internal tub (7) respect to the pipes from the pumping system, the pipes connected
to the tub have intercalated stretches of flexible hoses (102) as it was indicated
in Figures 17 and 18.
[0087] The washing by means of cavitation is produced, as it was mentioned, by means of
a special exhausts series whose suction is connected (38) to a steam generator (57),
in order to be fed by a re-circulating pumping system of the water into the tub, connecting
the discharge (8) of pump (18) to the special exhaust and the suction of this (19)
to the filter (203) in the core of the mean tub (7). The exhausts point their discharge
jets (36) within the tubs in adequate direction and from the upper of these. The feeding
tubes of the exhaust have a flexible portion (217) in order to can change the direction
of the exhaust jet during the washing and in order to remove the exhaust before removing
the small basket described in the following paragraph.
[0088] Inside the internal tub is a small basket (212) with the same profile or shape of
the internal tub, except that it does not have the outer wall and it is fastened by
a hollow and central conical body (213), which in dismountable form and of easy registration
is coupled an equal conical prolongation from the coupling. The upper portion of the
conical body (213) has an eyebolt (214) which serves to pull up with a crane the small
basket and to remove the washed clothes.
[0089] Figure 25 is a variant of the rotary washing system, similar to that from Figure
9, except that in this figure the balancing system in the centrifuging is equal to
that described in Figures 19 and 21, with the special supports (189) of the mean tub
(7), the bushing (185) for the rotation of the internal tub (14) and the flexible
hoses (102) intercalated in the connectors of the pipes. The steam feeding to the
exhausts with out diffuser (221) is equal to that described in the Figure 9, wherein
the generated steam in the fixed chamber (57) is conducted by the tube (68) fixed
to the closed box (108), in which the steam is transferred to the rotary vertical
portion of the central tube (38) which drives the steam. Furthermore, in this case,
the rotary tube (38) also serves as impeller shaft of the two planetary reducers (2)
and (225) which move the central hollow post which is divided in two portions. The
upper portion of the post (224) rotates, impelled by the above reducer (2); in a single
sense such as the helical plate (4) joined to this portion pulls to the clothes, as
in above figures, downwards. The bottom portion of the post (1) rotates oscillatory
by means of the double planetary special reducer (225) from below, which operates
in such a way that the blades (12) joined to this portion of the post oscillate as
a common washing machine. The steam transference to the rotary tube (38) and the operation
of the reducers impelled by this tube will be described in detail in the following
Figure 26.
[0090] The feeding of the rotary washing system consists of a first great diameter fixed
tube (101) which enters centrally below the centrifuging casing (23) and it drives
the flow which comes from the pump discharge, in similar form than in Figure 9. This
first tube is introduced into a second tube (100) which gets down, joined in its upper
portion to the center of the core of the internal tub (14), until support centrally
the Pelton-type special turbine (25). By above of the second tube (100) it is introduced
into this third tube or rotary tube (48) until this slightly assets by means of a
brake shoe (99) over another brake shoe in the upper edge of the second tube. The
first and the third tube are introduced with fine adjustment as a pillow block.
[0091] The upper end of the rotary tube (48) is extended gradually in conical form (220)
until flow, centrally, and below, within a closed cylindrical chamber (97) of low
height, great diameter and housed in the core of the internal tub (14), spite of the
bell-shape chamber of the Figure 9 or 7. To guide better the output of the flow in
the drainage of the rotary tube (48) over this is placed a conical appendix (98) with
the vertex downwards. The water flow which is coming out from the rotary tube (48)
circulates radially within the cylindrical chamber (97) and it is extended gradually
within the successive concentric sections of the chamber, which increase their area
according they are separated of the center. Thus, the speed of the flow is decreasing
in its transit by the conical and cylindrical portion; in such a way that the pressure
losses by the change in the flow direction are minimal. Moreover, the flow is distributed
within a section radial series of the chamber whose walls (22) converge son that (see
cutting BB') each section guides the flow towards an output (107), circular and tangential,
connected to the input tube (40) of the Venturi from a respective exhaust without
diffuser (221), placed in such a way that in the chamber perimeter (97) which its
output tube (36), a little curved, discharges in a convenient and tangential direction
water jets and steam bubbles which produce cavitation in the sinus of the clothes
and impels, by reaction, the rotation of the cylindrical chamber over a rotary tube
(48). Additionally are added in each section a curved and radial plates (223) for
better guide of the flow towards the exhausts.
[0092] The bottom enlarged portion (226) of the vertical portion of the steam conductor
tube (38) is fixed centrally above the cylindrical chamber (97) so that the tube rotates
with this and it serves as tube impeller of the reducers, as it was mentioned. On
the other hand, the steam driving towards the suction of the exhausts (221) continues
by other horizontal tubes (38) which radially are from the bottom portion (226) of
the vertical portion of the tube.
[0093] Since it is necessary for the operation of the planetary speed reducers (2) and (225)
that the structure which supports the gears of these stays fixed, a bar (94) joined
to the mean tube (7) is welded to the steam transference box (108) and which is integrated
to such structure.
[0094] Figure 26 shows in detail the system of the two planetary reducers (2) and (225),
housed respectively in the upper (224) and bottom portion (1) in which is divided
the central post, and which produce the rotary movement of the helical plate (4) and
the oscillating movement of the blades (12) as it was described in the Figure 25.
Both reducers are impelled by the same vertical and central portion of the tube (38)
which also drives the steam to the special exhausts, as also was briefly mentioned
in such above figure.
[0095] As well as in Figure 9, the supporting structure (80) of the reducers gears is integrated
to the box (108) which transfers the steam driven by the fixed tube (68) to the upper
rotary end of the tube (38) same which enters into the box through a passing hole
with mechanical seal (71) to avoid leaks. The box (108) is fastened to the mean tub
to fix the entire structure (80).
[0096] Below the box (108) is the planetary reducer (2) which comprises the central gear
(79) mounted on the impeller tube (38) the intermediate gear (96) and the box (244)
of the peripheral external gear which, to be joined to the upper portion (96) of the
central post, makes rotating to this and its helical plate (4) in a single sense.
The reducer rotates supported in the bushings (239) over a tubular rounded portion
(227) of the structure (80).
[0097] The second reducer (225) which moves to the bottom (1) of the central post really
is a double reducer with two systems, aligned one over the other one, of planetary
gears (233) and (243); each of these systems has a central gear (235) mounted on a
hollow shaft (241), so that these shafts are independent between them and they rotate
over the aligned bushings (234). The upper end of the hollow shaft of the above gear
and the bottom end of the gear shaft below, outstanding from its bushings, have the
radial bars (231). Inside the two hollow tubes (241) runs a ratchet tube (240) with
other bars or vertical locking bars (230) in each end in order they can be lashed
with the radial bars (231) The length of the ratchet tube (240) is such that, moving
upwards or downwards, it lashes by itself with one of the two hollow shafts (241)
of the central gears, keeping free the rotation of the other gear. Within the ratchet
tube (240) is the impeller tube (38) which rotates in a single sense and drag in its
rotation, by a wedge (237), to the ratchet tube (240), which in its turn impels the
central gear to which is lashed in this moment.
[0098] The key slot (236 in which is loosely housed the wedge is larger than this, so that
the ratchet tube (240) has enough freedom to displace upwards or downwards.
[0099] It is observed, in Figure 26 that in the upper system of planetary gears (233) the
quantity of intermediate gears (232) is a non number and in the bottom system (243)
the quantity of this gears (242) is a pair number, therefore, to link to the ratchet
tube (240), which rotates in a single sense, to one or another system will make that
one of them rotates in contrary sense to the other one. Thus in this way as the peripheral
gears of the two systems are joined to the bottom post (1) this will oscillate to
certain frequency together with its blades (12), as it get up or get down alternately
the ratchet tube (240). The central prost supports its oscillation on bushings (239)
which rotate over the tube (227) of the structure (80) at the upper portion and over
the tube (38) at the bottom. The upper or bottom vertical position of the ratchet
tube (240) is controlled by means of a spring (238) and the action of a bobbin (229)
over the magnetic nucleus (228) mounted on the ratchet tube (240) or by the cam system.
[0100] Figure 27 is a variant of the industrial washing machine of two tubs of Figure 24,
in combination with the portion of the Figure 25. In this new version, the mean tub
(7) has flat core but it configures a circular waterway closed together with the shape
of the internal tub (14), furthermore, the central connector to the washing system
of the feeding tube (8), or of the discharge of the pump (18) from the closed pumping
circuit, is vertically for the core of the mean tub, so that it is connected with
a rotary tube (48), introducing with slight adjustment this within that as pillow
block. In this case, the upper end of the rotary tube (48) is joined to the core of
the internal tub (14), as in Figure 25, it flows in conical shape within a cylindrical
chamber (97) which feeds a exhaust series (221) without diffuser whose output tubes
(36) direct its discharge over a dragging zone, formed this by a curved plates (44)
joined to the central body of the small basket (212) and the core (45) of the same
small basket which serves to remove the washed clothes, as it was described. The central
cylindrical body (219), which constitutes the inner wall of the waterway, is joined
to the upper portion of the cylindrical waterway (97) which likewise is joined to
the core of the internal tub (14), integrating a single piece.
[0101] The supports (189) of the mean tub, the steam chamber (57) and the feeding tubes
(38) of this to the exhaust are the same described.
[0102] The rotation of the internal tub (14) in the centrifuging, which is supported in
a brake shoe over a bushing (185) in the core of the mean tub (7), is impelled by
a motor (218) whose vertical shaft (245) penetrates axially within the vertical portion
of the feeding tube (8) thorough a hole practiced in the bottom portion of a bend
to 90° of the same vertical portion of the tube, sealing the passing of the shaft
by a mechanical seal (71). The upper end of this shaft is joined to the inner of the
bottom enlarged end of the rotary tube (48) by radial enlarged arms (246) which not
avoid the flow passing, so that the motor (218), to work, makes rotating the tube
together with the internal tube (14). During the washing the motor can rotate in opposite
sense to the flow circulation within the tub, so that the dragging zone displaces
against this flow and improve the circulation of the clothes.
[0103] Figure 28, is a variant of the washing system of a vertical washing machine of two
tubs (7) and (149 similar, in part, to the systems of the Figures 9 and 25. As in
Figure 9, the discharge (8) of the pump (18) is connected, intercalating in this case
a hose (102) between both, with a central fixed tube (101) which enters from the centrifuging
casing (23) and anchors in this, to then pass through the core of the internal tub
(14) through a passing hole slightly adjusted to the same tube, which raises inside
the tubs until close the upper portion thereof. At the upper end of this first tube
(101) is introduced a second rotary tube (48), with light adjustment so that it can
rotate within the first tube, which is supported by a brake shoe (99) over other brake
shoe at the end of the first tube. It is observed that the system does not use a central
hollow post. To allow, in the centrifuging, the centered rotation over the bushing
(185) of the internal tub (14) within the mean tub (7), is used, for instance, the
same supports system (189) of the mean tub of the figures 20 or 21.
[0104] The upper end of the rotary tube (48) flows to the inner of a widen bell-shape closed
chamber (97) of double wall, in a same shape and with the same function that the similar
chamber showed and described in Figure 9, except that, in this case, the periphery
of the core of such chamber (97) is connected by convergent surfaces, to the inputs
of a series of Venturi tubes (39) belonging to the special vertical exhausts without
diffuser, whose output tubes (36) discharge downwards water jets and steam bubbles
which cavitate in the sinus of the clothes, generating currents which drag the clothes
and which, guided by the curved core (45) of the internal tub, they follow closed
paths on vertical planes from the center to the side of the tub and all around this.
It is observed in the Figure that the exhaust series (39) are slightly deviated from
the vertical a same angle, with the purpose that the small horizontal component of
the jets reaction which get out by the output tubes (36) impel , over the rotary tube
(48), the rotation of the chamber and the exhaust around the tub.
[0105] Additionally, to help the circulation of the clothes within the internal tub (14),
in the core of this, are fixed the radial blades 812) which rotate with the tub when
the pump (149) is activated which feeds (17) the jets which impel the Pelton turbine
(25) of the internal tub at the centrifuging cycle, as it was described. This action
is made in short periods during the washing, alternately with the performance of the
pump (18) of the hydraulic circuit of the same washing; in such a way that in this
short periods, the clothes which are in the tub core are impelled by the rotation
of the blades (12) towards the periphery, pushing and provoking the movement of all
the clothes within the currents produced by the exhausts.
[0106] Finally, the steam feeding to the exhaust is made in similar form to that described
in Figure 9. On the cupola center of the bell-shape chamber (97) is fixed a closed
box (108) for the steam distribution by means of a tube series (38), connected to
the inner of the same box, and which drive the steam to each of the suctions of the
different exhausts in which finishes the bell-shape chamber (97). In its turn, the
closed distribution box (108) is fed by a tube (68) which enters into the box, by
above, through a center bushing and adjusted to the tube, so that the box can rotate
over the tube (68) which drives the steam from the steam fixed chamber (57). The input
of the tube (68) is sealed by a mechanical seal (71).
1. A washing, rinsing, wringing machine for clothes within a mean tub which contains
another inner tub with holes for the passing of the water flow towards the mean tub;
wherein, the tubs are connected in series with a hydraulic closed pumping circuit
which consists of a pump which takes continually the water from the inner of the tubs
and the discharge, through a feeding tube, again within them, to produce the energy
of the re-circulating water flow which moves to the systems; the discharge of the
pump is connected, by control valves, either to the washing system or to the wringing
by centrifuging to activate to any of the two systems or it is used, optionally, a
centrifuge pump for the hydraulic washing circuit and other for the hydraulic centrifuging
circuit, each of which works with different rotary sense and they are impelled by
a same motor which has rotation change to activate one or another pump; firstly the
closed pumping circuit feeds and activates the washing system which consists of a
special exhaust without diffuser whose suction is connected to a steam generator to
low pressure; this generator is a closed steam chamber in which a heater heats the
water, direct or indirectly, so that the exhaust discharges, in certain adequate direction
within the washing tub, a water jet with steam bubbles which cavitate in the sinus
of the clothes for wash; within the washing tubs is a dragging zone of the clothes,
or deflector space of the flow, limited by two surfaces separated to certain distance,
on in front of the another one, warped against and converging in certain degree, in
such a way that the water and steam jet which gets out by the discharge of the exhaust
directed towards such zone, in direction of the convergence, produces a positive impulse
over the clothes in this zone, so that the same go circulating for such space; furthermore,
the machine has a rotary washing, moving and circulation system of the clothes within
the tubs which is activated by the water flow of the closed pumping circuit and it
is comprised of a broad tube or hollow post of great diameter housed centrally within
the tubes and called central hollow post; this post has a helical wide plates welded
in its around and throughout; the rotation of the wide hollow post, which can be continue
or slowly controlled by means of a special mechanism, is produced, through a direct
coupling or planetary speed reducer, by a motor centered with the post and impelled
by an axial flow turbine or by a rotary tube, also as center motor shaft, which conduces
the water flow of the system to be connected, by means of a rotary coupling between
both tubs, to the end of the feeding fixed tube at turn is introduced centrally by
the upper or bottom of the tubs; for produce the impulse of the rotary tube is used
a system of make in this two folding to 90° in its free end which place to the output
of the tube in perpendicular position and to certain distance of the geometrical shaft
or of rotation of the own tube, in such a watt hay the water jet which gets out from
the tube origins, by reaction, the pair of forces which produce the rotation, at the
same time that the jet is projected in the direction of the dragging zone,; this dragging
zone is formed with the bottom end of the helical plate as upper surface and, as bottom
surface, the same surface of the tub core, or the surface of a horizontal plate welded
to a rounded cover, within which is the folded portion of the rotary tube whose final
end outstands of the cover by a radial plane which interrupts the form of this, being
this cover separated or integrated to the central post, in front of the dragging zone
a deflector plate stays placed, which deviates the water flow a little upwards and
to the periphery of the tub, as option to move the clothes, are used two planetary
central reducers, aligned and with different rotary sense, coupled to the hollow central
post which has radial blades at its bottom, in such a way that a tube or centered
shaft, which rotates in a single sense, impels alternately by certain ratchet system
to the central gear of each reducer to produce in the post and the blades a oscillating
movement; the exhaust is connected to a series with the feeding tube or with the rotary,
before or after of the rotary coupling between them, and it forms part of the water
conduction; the steam chamber and the exhaust can be fixed or rotate together with
the rotary system; if the steam chamber is fixed and the exhaust rotates with the
rotary system, the steam conduction between the steam chamber and the suction of the
exhaust is made by means of a first stretch of the fixed tube which comes from the
steam chamber and connected to a second stretch which rotates feeding to the suction
of the exhaust, therefore it is used a rotary or mechanic seal intercalated between
both tubes; if the steam chamber rotates together with the rotary washing system,
the heat of the water within it is made indirectly by a electric transformer whose
primary is fixed and the secondary rotates with the fed system, to the same time,
to a electric resistant within the chamber; or also it is effectuated using a heater
close to the walls of the chamber or the system of a pair of metallic isolated rings
which feed electrically by brushes, are mounted on a shaft which rotates together
with the steam chamber and they are connected to the resistance by sealed wires; additionally
the tubs have in their inner side wide helical plates to guide the circulation of
the clothes, and is disposed a system in the entrance of the pump which disintegrates
and grind the loose threads coming out of the clothes; the clothes wringing system
by centrifuging in the inner tub consists on produce the rotation of this by means
of an horizontal turbine special Pelton-Type, joined to the center of the tube core,
which impelled by the water jets which provide a peripheral nozzles series connected
to the discharge of the pump from the corresponding hydraulic circuit, so that the
turbine housed within a cylindrical box or casing, called centrifuging chamber and
is as prolongation of the mean tub core; this Pelton turbine consists of a vertical
box in which is introduced to the middle and they are fixed to its side, a distributed
series of ladle-shape radial buckets; these buckets direct their output inner edges,
slopping a little downward, in almost radial form towards the center of the box, wherein
this is connected with a vertical discharge tube from which is evacuated the jets
water which impel to the turbine; so that the rotation of the inner tub be balanced,
this makes rotating while it floats in the contended water, to certain prefixed level,
within the mean tub, in such a way that the inner tub rotates freely respect to any
virtual shafts which passes by the center of gravity of the tub and the clothes; furthermore,
below the tub is placed a centered counterweight to stabilize the flotation of the
inner tube; the machine has a system to condition the flotation of the inner tub within
the mean tub, which consists, after previously draining the water of the mean tub,
in evacuate by gravity the water of the inner tub through the check valves, then to
fill again of water the space between the tubs to the prefixed flotation level; another
system to provoke that the inner tub rotates over any virtual shaft which passes by
its center of gravity are used the special supports which support to the tub allowing
it to displace, freely, in any lateral direction or around of the virtual shaft, to
the turn that the same rotates over its geometrical shaft, in such a way that the
result of both movements is the rotation of the tub over the virtual shaft, without
supporting over a rigid or fixed shaft; the pipes have intercalated stretch of flexible
hoses to not limiting that the set of tubs and the connectors to these from the same
pipes can move laterally; to close the virtual shaft to the geometrical shaft of the
inner tub, this has a peripheral chamber which store certain quantity of a heavy flow;
in this case the balancing chamber is annul and forms all the side of the inner tub,
in such form constructed which avoid the redistribution of the balancing flow within
this to close, when increase the balancing, the virtual shaft gives rotation to the
geometrical shaft for the same tub; the inner tub is just of the necessary height
to contain to the wet clothes, situated in its core before the centrifuging, and its
side is housed within a broadening which the mean tub has for such purpose, remaining
certain space to contain the water in which the inner tub floats and rotates; the
separation between the upper edge of the inner tub and the broadening step from the
mean one, is covered by means of a annular gate with "L"-shape section, whose vertical
portion is slightly adjusted to the diameter of the mean tub and the horizontal portion
is supported in such upper edge by material plates resistant to the friction; if the
inner tub floats, this is buffered in its oscillation to rotate by anti-friction plates
or bearings placed between the cores of the two tubs and between the lateral portion
from both; if is used a rotary tube and the inner tub does not have output holes by
flotation reasons, it is placed within the inner tub a third tub with multiple perforations,
separated a little from that, in such a way that the water flow is drained by a vertical
draining tube centered in the inner tub core and which is prolonged until near the
core of the centrifuging chamber, wherein is the mouth of the suction tube of the
pump, the draining tube has a check valve which avoid the return of the water to the
inner of the tub.

tube and upper, passing though the fixed tube, it serves as support of the rotation
over the other side of the brake shoe; other means use for this consists in adjusting
firmly, as pillow block, a bushing to the external diameter of the rotary tube, slightly
joined together the bushing between its lateral faces by a bottom brake shoe mounted
on the rotary tube and a upper screw nut screwed to the free end of the same tube,

and radial which together with the core of the small basket form dragging zones placed
in front of each exhaust; the vertical portion of the draining or feeding tube for
a bend to 90° under which is placed a motor of such form that its motive axis passes
through the bend by a passing hole and it is axially housed within this portion of
the tube, sealing the passing of the axis by means of a mechanical axis; the upper
end of the motive axis within the feeding tube is joined, by the radial wide arms,
to the inner of the bottom end of the rotary tube joined to the inner tub, thus, to
works the motor the axis of this makes rotating the rotary tube together with the
inner tube during the centrifuging cycle.
