[0001] The present invention refers to an aspirating apparatus particularly for toilets.
[0002] It is known that nowadays the time spent on body hygienics takes an unnegligible
fraction of the daytime. The places dedicated the daily toilet, such as the toilets,
assume a still growing importance regarding comfort and practicability. In this point
of view it is most important that the toilet never presents the typical bad smells
produced by the toilet users. One of the most used ways to make a toilet nice and
acceptable is to have the room ventilated. A very diffused ventilation means is the
centrifugal aspirator typically placed over the toilet bowl. However such aspirator
is much in use, in this position it is not free from inconveniences. In fact, owing
to the particular position, the time necessary to aspirate the air quantity useful
for a quick air change is elevated. The organic smells deriving from a toilet bowl,
for example, need to be aspirated quickly to avoid inhalation by the user, whereas
the time necessary for the user to stay inside the toilet is less than the time necessary
for the air change. Furthermore, the disposition of the aspirator over the toilet
bowl is so that the aspirated flow forms an air column from the toilet bowl area where
the user is sitting right up to the aspirator mouth; in this air column with its bad
smells the toilet user is emerged. Even, in these last years in the field of the resident
building there is a tendency, motivated by lack of useful space and by cost restraining,
to realize houses groups having blind bathrooms or toilets. In this kind of toilets
the air change obviously results fundamental. The aspirator outlet has to be connected
to a chimney vent flue which has to be planned during the construction of the building
and thus representing realization costs as well as restraints for the houses groups
layout
[0003] A second example of aspirating apparatus for toilets is constituted by traditional
aspirating means connected by means of a piping, being rigid in the first section
and elastic in the end section, to the posterior part of an ring duct obtained in
the seat of a toilet bowl. Said duct along its development is provided with a plurality
of openings flowing out on the lower part of the seat in the direction of the bowl
cavity. The apparatus is activated by a microswitch placed near to the seat which
according to the horizontal/vertical seat position attivates or deactivates the aspirating
means. The main inconvenience recognized in this solution consists in the fact that
the aspirating action is exercised in a position rather distant from the deposition
area for urine and faeces which are the origin of the bad smells. A second inconvenience
is recognized in the very laborious cleaning of the openings. A third inconvenience
is recognized in the fact that the apparatus is deactivated when the toilet bowl is
used for urine deposition as the seat is in vertical position.
[0004] A third example of aspirating apparatus is disclosed in JP-A-2003096874. It comprises
a deodorizing pipe connecting the back wall of a bowl for water closet to a drain
pipe for human waste in order to transfer the smells from the bowl to the drain pipe,
a deodorizing fan installed along this deodorizing pipe between said drain pipe and
said bowl in order to aspirate smells from said bowl and send it to the drain pipe,
a check valve located along the deodorizing pipe upstream the deodorizing fan in order
to allow the transfer of the smells only from the bowl to the drain pipe. The main
drawback of this solution consists in that the deodorizing pipe leads to the back
wall of the bowl where the faeces go down towards the deposition area so that the
opening of the deodorizing pipe tends to obstruction. This drawback is made worse
by the fact that the washing water doesn't wash the inner surface deodorizing pipe.
[0005] A fourth example of aspirating apparatus is disclosed in BE-A-1008248. It comprises
a deodorizing pipe connecting a bowl for water closet to a chimney pipe in order to
transfer the smells from the bowl outside and a deodorizing fan installed along this
deodorizing pipe in order to aspirate smells from said bowl and send it to the chimney
pipe. In particular, the deodorizing pipe defines in the bowl a circular duct equipped
with a plurality of aspirating openings all around the bowl turning towards the cavity
of the bowl and 40 cm distant from the surface of the water inside said cavity. A
first drawback of this solution consists in that the aspirating openings are far from
the deposit area of the urine and the faeces so that the aspirating action isn't particularly
efficacious. A second drawback consists in that the aspirating openings on the back
wall of the bowl where the faeces go down towards the deposition area tend to obstruction.
This drawback is made worse by the fact that the washing water doesn't wash the inner
surface deodorizing pipe.
[0006] The aim of the present invention is to provide an aspirating apparatus particularly
for toilets which solves the problems evidenced in the prior art types.
[0007] Within the scope of the above-mentioned aim, one important object of the present
invention is to provide an aspirating apparatus for toilets which limits the inhalation
of bad smells by the toilet user.
[0008] A further important object of the present invention is to provide an aspirating apparatus
particularly for toilets which allows to reduce the realization costs concerning aspirating
plants for toilets in the houses groups.
[0009] An additional object of the present invention is to provide an aspirating apparatus
particularly for toilets which allows to optimize, during the projecting stage of
the houses groups, the layout of said groups as far as toilet aspirating systems are
concerned.
[0010] One of the last objects of the present invention is to provide an aspirating apparatus
for toilets which can be produced using known systems and technologies.
[0011] This aim, as well as these and other objects appearing in the following, are achieved
by an aspirating apparatus particularly for toilets according to claim 1.
[0012] Further features and advantages of this invention will result apparent from the description

[0013] With particular reference to the mentioned figures 1 and 2 the aspirating apparatus
for toilets according to the invention is globally indicated by the reference number
10. Said apparatus 10 comprises an aspirator 11 in the inlet connected operationally
to outlet pipe 12 from the flush box 13 of a toilet bowl 14. Said aspirator 11 is
operationally in the outlet connected to the outside 14a of the room housing the toilet
14. In details, in this execution form, the aspirator 11 is operationally connected
in the outlet to the part of the outfall sewer conduit 16 of said toilet bowl 14 situated
downstream the siphon 17 of same toilet. The apparatus 10 comprises flow interception
means 18 situated between said part of the outfall sewer conduit 16 of toilet bowl
14 and the outlet pipe 12 of flush box 13, these means are described in the following.
Said flow interception means 18 comprises a float check-valve 19, in itself of known
type, disposed upstream the aspirator 11. Moreover, in this described embodiment,
said flow interception means 18 also comprises a motor-driven valve for the bidirectional
flow blocking 20, either butterfly valve or ball valve of known type, placed downstream
said aspirator 11 between said antibackflow valve 15 and said part of outfall sewer
conduit 16 of toilet bowl 14. Operationally said motor-driven valve for the bidirectional
flow blocking 20 is associated in the functioning to the aspirator 11; in practice
when the aspirator 11 is switched off the motor-driven valve 20 is closed, and when
the aspirator 11 is functioning the motor-driven valve is open. The aspirator 11 is
f. ex. of the type for saunas and is substantially tight being associated to an antibackflow
valve 15 of mechanical type, placed downstream the same aspirator and particularly
in correspondence with its outlet; said antibackflow valve 15 is part of said interception
means 18. The apparatus 10 also comprises a flow gauge 22 placed upstream the aspirator
11; in details, said flow gauge 22 is disposed between said float check-valve 19 and
the aspirator 11. If wanted, said flow gauge 22 could be placed downstream aspirator
11. Said flow gauge 22 is operationally associated in the functioning with aspirator
11; in practice when the aspirator is functioning and if the flow gauge 22 does not
note the passage of air, it means that there is some obstruction in the plant piping.
In this case the aspirator 11 interrupts its functioning. For this reason the float
check-valve 19 comprises, in this embodiment, a vibrator (not indicated in the figures)
of known type in combination with this valve type 19, which associated with said flow
gauge 22 allows to release the float of the valve 19 when, f.ex. in presense of phenomenons
like condensation or other, it tends to remain blocked in its own seat packing. Together
with the flow gauge it is possible to associate a flow display of known type (also
not indicated in the figures) such as f.ex. a small swirl inserted into a portion
of the piping formed like a loop and equipped with a window upstream the aspirator
11. Said flow display can also be placed downstream the aspirator 11. The apparatus
10 also comprises a presence sensor 23, i.e. a photocell, for an user being near to
the toilet bowl 14; said sensor 23 is connected to a time switch (not drawn in the
figures) connected with the control of the aspirator 11. If wanted, instead of the
presence sensor 23 to actuate the aspirator, it is possible to use a manual push-button
control. The aspirator 11 together with the flow gauge 22, the antibackflow valve
15, the float check-valve 19 and the motor-driven valve for the bidirectional flow
blocking 20 are conveniently housed inside a cabinet 30 disposed on the wall next
to the toilet bowl; said cabinet 30 is equipped with a door to allow control of the
plant working and for handy and easy maintenance.
[0014] Figure 4 illustrates a bowl for toilets indicated globally by reference number 114.
Said bowl 114 is equipped with a couple of aspirating ducts 131 departing from the
back wall of said bowl 114 where they are connected by means of pipings 132 and float
check-valves or motor-driven valves to the aspirating means (components not illustrated
in figure 4). Said couple of ducts 131 extends along the lateral walls of said bowl
114 until approximately the area before the outfall 133 of bowl 114. The end portion
of said couple of ducts 131 is provided with a plurality of openings 134 comunicating
with the cavity 135 of bowl 114 and turned towards the outfall area 133 where urines
and faeces deposit. This preferred embodiment of the invention offers the advantage
to avoid the necessary interventions of realizing the connection between the flush
box pipe and the aspirating ducts of the aspirating means.
[0015] Figure 5 illustrates a toilet bowl globally indicated by reference number 214. Said
bowl 214 is equipped with a U-formed aspirating duct 231 obtained in its front wall
and side walls. Said U-formed duct 231 is connected to the end 232 of the back portion
of ring duct 233 for the washing water distribution in the cavity 233 of bowl 214.
Finally, said U-formed duct 231 along the curved portion is equipped with a plurality
of openings 234 comunicating with cavity 233 and turning towards the outfall 235 area
of the bowl 214 where urines and faeces deposit. This preferred form of the invention
has the advantage that the cleanliness of the U-formed duct 231 and the openings 234
is particularly efficient because executed through each flush dispersing the washing
water in the ring duct 233 and in the U-formed aspiration duct 231 and running out
by means of the openings 234 in the cavity 233 ending into the outfall 235.
[0016] According to an embodiment not illustrated in the execution of figure 5, the U-formed
duct can be replaced or act together with one or more ducts provided in the bowl walls
as the ducts indicated by reference number 131 of figure 4 connected in the inlet
to the ring duct 233 for washing water distribution.
[0017] Figure 6 illustrates an embodiment of the apparatus outlet globally indicated by
reference number 310. As shown in this figure the aspirating means (not illustrated)
are localized inside a wall cabinet 330. Operationally the aspirating means are connected
in the inlet to the ring duct for washing water distribution obtained in the walls
of the bowl 314 by means of a float check-valve or motor-driven valve (not illustrated
in figure 6) and a piping joining in the cross-connection from bowl 314 to the box
containing the washing water. The aspirating means operationally are connected in
the outlet by means of a piping 331 to the exhalation valve 332 of bowl 314. Along
the piping 331 which connects the aspiration means and the exhalation valve 332 is
positioned a check-valve 333 of motor-driven type, which prevents the return of the
smells. Said embodiment of the apparatus outlet offers the advantage of avoiding a
suitable chimney vent flue to vent the smells into the free air or into the sewer.
[0018] Where the aspirator 11 is located under the flush box 12 the apparatus will be provided
with a check-valve on the duct connecting the the bowl 14, 114, 214 and 314 to the
aspirator 11 in order to avoid the that washing water rises till the aspirator 11.
[0019] The working of the present invention is as follows:
The user approaches the toilet 14 and the aspirator 11 is activated by the signal
coming from the presence sensor 23. To the starting of aspirator 11 corresponds an
opening signal for the motor-driven valve for bidirectional flow blocking 20. The
float check-valve 19 allows passing of the air from outlet pipe 12 of flush box 13
of toilet bowl 14 to the aspirator 11: the airstream lifts the float ball and open
the passage; without the airstream the float ball remains in its closing position
in its proper seat avoiding the passage in opposite direction of the bad smells remaining
trapped in the part between the motor-driven valve for bidirectional flow blocking
20 and the float check-valve 19. The motor-driven valve 20 isolates completely apparatus
10 from the sewer network downstream the toilet bowl siphon 17 during the non-operation
step. When a certain time has passed from flush actioning the aspirator will stop
working and the motor-driven valve 20 will be closed.
In an other version of said apparatus 10 (not evidenced in the figures) said one-way
float valve 19 can be replaced by a motor-driven three-way valve of known type. Said
motor-driven three-way valve can assume two different conditions: a first condition
defined "0" with the aspirator 11 isolated from the outlet pipe 12 but operationally
connected with a place outside toilet 14, and a second condition (of aspiration) defined
"1" with said aspirator 11 connected only with said outlet pipe 12. The reason for
using this three-way valve is to reduce the residual humid air inside the aspirator
during the non-operation steps; in fact during ventilator inactivity, if the float
check-valve 19 is present, the previously aspirated air will remain blocked inside
the circuit between the motor-driven valve 20 and the valve 19. The humidity of such
blocked air will dammage the aspirator 11 as well as the other circuit components.
With the motor-driven three-way valve, after the aspiration from the toilet bowl (three-way
valve in position "1") commutating the three-way valve in position "0", the aspirator
will recall, for a certain piece of time, air from outside the plant replacing it
with the humidity saturated air; then the aspirator 11 will switch off, the motor-driven
valve for bidirectional flow blocking 20 will close and the three-way valve must be
left in position "0"; when the aspiration from the toilet bowl is starting the three-way
valve is commutated in position "1". A basic embodiment of the invention, shown in
the drawing of figure 3, comprises the aspirator 11, the antibackflow valve 15 which
can be not perfectly tight, and the float check-valve 19 blocking the residual bad
smells coming from the sewer downstream the siphon 17 of toilet bowl 14. An alternative
embodiment, not shown in the figures, is composed of the aspirator 10 which aspirates
from said outlet pipe 12 of flush box 13 of toilet bowl 14 and releases to the outside
directly in the atmosphere by means of a chimney vent flue and from the flow interception
means 18 such as for ex. the antibackflow valve 15. Other embodiments of the aparatus
could comprise automatized comands for flush box discharge combined with the presence
sensor 23.
[0020] In practice it has been observed that the described apparatus according to the invention
solves the problems evidenced in the known aspirating apparatus for toilets; specially
with the present invention it is provided an aspirating apparatus particularly for
toilets which permits to aspirate from an area of the toilet bowl very next to the
origin of the bad smells.
[0021] Furthermore, with the present invention it is provided an aspirating apparatus particularly
for toilets permitting to discharge the bad smells in the existing sewer network,
avoiding therefore the need of chimney vent flues and allowing evident projection
and building advantages.
[0022] The invention conceived in this way is susceptible of numerous modifications and
variants, all of them entering into the ambits of the present invention concept; furthermore
all details might be substituted by other technically equivalent elements.

specific use, as well as the dimensions might be whichever possible within the limits
of the needs and the state of the art.
