FIELD OF THE INVENTION
[0001] The present invention concerns a fan usable in closed domestic or public places,
to create a stream of air for ventilating or conditioning the surrounding environment.
[0002] The term fan as used hereafter is intended to mean, in a broader sense, any apparatus
whatsoever able to supply ventilation, conditioning, cooling, heating, thermo-ventilation,
dehumidification or purification of the air.
BACKGROUND OF THE INVENTION
[0003] Fans for rooms are known, substantially configured as a column, with a containing
structure which houses the mechanical components that generate the stream of ventilation
or conditioning air, and a zone from which the stream of air is emitted, comprising
one or more exit apertures through which the stream is emitted toward the environment.
[0004] In the most typical and widespread solutions, the exit aperture is generally located
in sight on the front part of the structure of the fan, often making the technical
components partly visible, for example the ventilation blades and/or the possible
heating means.
[0005] This can give the fan an unpleasant esthetic effect, preventing the manufacturer
from obtaining a clean profile, without discontinuities and thus lowering the esthetic
value of the fan.
[0006] Furthermore, since the technical components face directly toward the space, they
are more subject to contact with dust or other dirt that can compromise the functioning
thereof.
[0007] Portable fans are also known, which do not have the internal components visible or
partly visible, or that do not have ventilation blades, but which have a stream of
air confined to a limited portion of space.
[0008] In particular, the stream of air is greatly limited in its distribution in the space,
which reduces its applicability and effectiveness.
[0009] Another disadvantage of many of the known solutions is that the air entering the
fan is taken in in a lower zone, where there is the motor, substantially in correspondence
with or near the base of the fan.
[0010] In this way, as well as taking in the air from the space, the fan also takes in the
dust which is present in large quantities on the base surface where the fan is rested.
[0011] Document
CN-A-104.863.871 for example describes a fan comprising a support base provided with an air suction
chamber, and a body that develops in a vertical direction, communicating with the
support base and provided with a plurality of slits made in the longitudinal direction,
through which the stream of air generated is emitted outside, in a direction imparted
by deflector elements provided in correspondence with the slits. In the solution described
in
CN-A-104.863.871, the entrance apertures for the air and the means to generate a stream of air are
necessarily provided in the support base, under the slits through which the air exits,
because the geometry and configuration of the vertical body do not allow a different
disposition of these components.
[0012] Document
WO-A-2012/017220 describes a fan comprising a body provided with apertures for the air to enter, inside
which body means to generate a stream of air are disposed, and a casing with an annular
shape, provided with at least a first aperture to emit a first portion of the stream
of air and at least a second aperture to emit a second portion of the stream of air.
Due to the disposition of the air entrance apertures and the means to generate the
stream of air, constrained by the configuration of the fan, the air sucked in can
contain dust or impurities that tend to deposit in correspondence with the ground.
[0013] Document
CN-A-105.351.230 describes a fan that exploits the Coanda effect to emit a stream of air toward a
user. The fan comprises a chamber provided with holes for the air to enter, inside
which chamber the means to generate the stream of air are provided and on which a
Coanda-type deflector is disposed with a section comprising an arched portion and
a V-shaped portion, and provided with slits for the stream of air to exit in correspondence
with the arched portion, which deflect the stream of air toward the tip of the V.
The solution described provides that the entrance holes and the means to generate
the stream of air are disposed in correspondence with the lower part of the fan, but
this causes the same problems as described above.
[0014] The solution described in
US-A-2015/0136997 concerns a fan device provided with a housing for the main body with a column shape,
provided with an entrance aperture for the air in a rear zone, and with an exit aperture
defined by a slit made longitudinally in a front wall of the housing of the main body.
The fan device comprises a blowing device disposed in the lower part of the housing
of the main body, configured to make the air circulate from the entrance aperture
to the exit aperture from the bottom upward.
[0015] One purpose of the present invention is to obtain a fan that overcomes the disadvantages
of known fans.
[0016] Another purpose of the present invention is to obtain a fan that returns a distributed
stream of air at uniform temperature, able to guarantee maximum comfort to the people
in the space where it is positioned.
[0017] Another purpose is to obtain a fan that requires minimum maintenance operations with
reduced frequency.
[0018] Another purpose is to obtain a fan that allows to vary the amplitude of the stream
of air at exit.
[0019] Another purpose of the present invention is to obtain a fan with great esthetic value,
having a front surface without discontinuities and defining a closed profile without
apertures to access the internal zone where there are the functional components of
the fan.
[0020] The Applicant has devised, tested and embodied the present invention to overcome
the shortcomings of the state of the art and to obtain these and other purposes and
advantages.
SUMMARY OF THE INVENTION
[0021] The present invention is set forth and characterized in the independent claims, while
the dependent claims describe other characteristics of the invention or variants to
the main inventive idea.
[0022] In accordance with the above purposes, the present invention concerns a fan for the
emission of a stream of air into a space.
[0023] The fan comprises a main body with a vertical development with respect to a support
base on which it is located in a condition of use, said main body defining an internal
housing compartment.
[0024] According to one aspect of the present invention, the fan has a longitudinal aperture
disposed in its rear zone, for the emission of the stream of air toward the outside,
and also comprises an air suction and distribution unit, located, at least for a substantial
part thereof, above the beginning of the longitudinal aperture, and a channeling element
positioned in proximity to the longitudinal aperture and cooperating with it to determine
the exit of the stream of air through the longitudinal aperture, so that the exiting
stream of air adheres to the external surface of the main body and is conveyed toward
the front of the fan.
[0025] According to another aspect of the invention, the external surface of the main body
has a rounded geometry substantially without discontinuities so that the stream of
air, exiting from the rear part of the fan, is conveyed adherent toward the front
part and then toward the external environment to be ventilated or conditioned.
[0026] According to another aspect, the channeling element has or is associated with means
suitable to subdivide the stream of air exiting from the longitudinal aperture into
two streams with opposite directions, so that the streams separate substantially in
correspondence to the longitudinal aperture and are separately conveyed adhering to
the external surface of the main body, toward the front part of the fan, where they
are at least partly rejoined and spread into the environment.
[0027] In this way, advantageously, a fan can be obtained that does not need blades, in
which the internal components are not visible to the user and whose visible surface
is without discontinuities, with a rounded profile that, as well as providing a pleasant
esthetic appearance, is functional for the emission and distribution of streams of
air into the space.
[0028] The invention also concerns a method to determine a stream of air exiting from the
fan.

DETAILED DESCRIPTION OF SOME EMBODIMENTS
[0031] Embodiments described here with reference to figs. 1-6 concern a fan 10 usable in
particular in closed spaces for ventilating air at room temperature, for cooling,
heating, thermo-ventilating, dehumidifying or purifying air.
[0032] The fan 10 comprises a main body 12 with a vertical development with respect to a
support base 18 on which it is positioned during use.
[0033] The main body 12 defines inside it a compartment 13 for housing functional components.
[0034] The fan 10 has a longitudinal aperture 16, disposed in the rear part of the main
body 12, and comprises a unit 14 to take in and distribute a stream of air W.
[0035] The air suction and distribution unit 14 is located, at least for a substantial part,
above the beginning of the longitudinal aperture 16.
[0036] The longitudinal aperture 16 is disposed on the opposite side with respect to the
space to be conditioned. In particular, the longitudinal aperture 16 is located in
the rear part of the fan 10, and the stream of air W exiting from the longitudinal
aperture 16 is deflected so as to reach the front zone located at the front of the
fan 10, as indicated by arrows F in figs. 3 and 4.
[0037] In general, the expressions "rear part" and "front zone" are only intended to define
a functional relationship between these two parts, which have to be substantially
opposite each other with respect to the main body 12 and the user.
[0038] According to some embodiments, the air suction and distribution unit 14 comprises
a rotor 15 provided with suitably oriented blades to determine the suction of the
air from the outside and its entrance into the main body 12.
[0039] The rotor 15 can be designed for example to obtain a centrifugal fan, an axial fan
or a mixed axial-centrifugal fan.
[0040] The air suction and distribution unit 14 also comprises a drive member 17 connected
to the rotor 15 by means of a drive shaft located in correspondence with the center
of the rotor 15.
[0041] The fan 10 also comprises a channeling element 20 positioned near the longitudinal
aperture 16 and cooperating with it to direct the stream of air W toward the outside.
[0042] The channeling element 20 is configured so as to allow the stream of air W exiting
from the longitudinal aperture 16 to adhere to an external surface 22 of the main
body 12. In other words, the channeling element 20 is able to deflect the stream of
air W exiting from the longitudinal aperture 16.
[0043] The channeling element 20 comprises an active surface 20a which, during use, is struck
by the stream of air W exiting from the longitudinal aperture 16. The active surface
20a can have a convex shape.
[0044] The channeling element 20 makes the stream of air W exiting from the longitudinal
aperture 16 in its travel toward the front zone of the fan 10 follow the profile of
the external surface 22 and be conveyed toward the front of the fan 10, as can be
seen better in figs. 3 and 4.
[0045] Furthermore, in cooperation with the external surface 22, the channeling element
20 is configured to determine a minimum passage section of the stream of air W exiting
from the compartment 13.
[0046] In one formulation of the invention, the external surface 22 has a rounded geometry,
substantially without any discontinuities, so that the stream of air W, exiting from
the rear part of the fan 10, is conveyed adherent toward the front part and then toward
the space to be ventilated or conditioned.
[0047] Within the field of the present invention, the rounded geometry can be defined by
a cross section that is substantially circular, regular oval, drop-shaped, compressed,
or such as to obtain a profile of the main body 12 that is substantially drop-shaped
or wing-shaped, or any other shape, even different from circular, suitable to convey
the stream of air W adherent to the external surface 22 without creating significant
variations in the development of the stream, and without creating disturbances, turbulence,
discontinuities or any other factor that could disturb the development of the stream.
[0048] The air enters inside the main body 12 through through entrance holes 27 made at
least above the longitudinal aperture 16, in the top part and/or on the upper lateral
wall of the main body 12.
[0049] The compartment 13 allows to channel inside the fan 10 the stream of air W from the
entrance holes 27 toward the longitudinal aperture 16.
[0050] According to a preferred embodiment, the main body 12 can be configured to have a
substantially cylindrical shape for the whole of its height.
[0051] In this way, the main body 12 has a circular cross section shape, that is, without
sharp edges and advantageously it is possible to make the stream of air W transit
adherent to the external surface 22 at exit from the longitudinal aperture 16, exploiting
the Coanda effect.
[0052] According to one embodiment shown by way of example in fig. 1, the main body 12 can
have a tapered shape in at least part of its vertical development.
[0053] In particular, according to an advantageous formulation, the main body 12 has on
its height a narrowing in section substantially in correspondence with the longitudinal
aperture 16.
[0054] In this way, thanks to the fact that in correspondence with the longitudinal aperture
16 a regular oval profile is formed, or drop-shaped, compressed, or wing-shaped, the
stream of air W is kept adherent to the external surface 22 for a greater segment
than it would be if the section were circular and constant for the whole height of
the main body 12. Consequently, the stream of air W that strikes the user will be
more intense and less turbulent.
[0055] In this variant embodiment, the diameter inside which the cross section of the main
body 12 is inscribed can be comprised in a range from 100mm to 230mm and the height
of the main body 12 can be comprised in a range between 750mm and 850mm.
[0056] The main body 12 can be configured to have a continuous surface in the front part,
while in correspondence with the longitudinal aperture 16 it has a profile folded
toward the inside, to define the longitudinal aperture 16 itself.
[0057] In this way, the particular rounded geometry of the main body 12 in correspondence
with the longitudinal aperture 16 allows to convey the stream of air W adherent to
the external surface 22, so as to form a surface film that is propagated then toward
the front of the fan 10.
[0058] According to possible embodiments, described for example with reference to fig. 3,
the main body 12 can have a geometric cross section with a profile 40 defined by a
polyline, which can be approximated by a plurality of convex arc segments S1, S2,
S3, ....SN located one after the other.
[0059] In particular, the polyline profile 40 is configured to generate a stream of air
in the front part of the fan 10 such as to guarantee a high level of comfort for a
user.
[0060] According to some embodiments, the profile 40 of the characteristic section has a
symmetrical shape with respect to a median plane M of the fan 10 which joins the front
part and rear part where there is the longitudinal aperture 16.
[0061] It should be noted that the profile 40 can affect only one zone of the main body
12, in particular that zone where the longitudinal aperture 16 is made.
[0062] In some embodiments, the longitudinal aperture 16 and the profile 40 can affect the
whole longitudinal (vertical) development of the main body 12, or only one portion
thereof.
[0063] According to some embodiments, in the direction of the stream of air from the longitudinal
aperture 16 to the front part of the fan 10, the successive convex arc segments have
a progressively decreasing amplitude and a progressively increasing radius of curvature.
[0064] According to some embodiments, the convex arc segments S1, S2, S3, ....SN are tangent
to each other.
[0065] According to some embodiments, for example shown with reference to fig. 3, the profile
40 can be approximated by at least three convex arc segments S1, S2, S3.
[0066] Even if in the following description we refer by way of example to three arc segments,
it is clear that there can be any number N of convex arc segments, for example five,
seven, ten, twenty, one hundred or more, provided that the convex arc segments have
a progressively decreasing amplitude with respect to each other in the direction of
the stream of air, and a progressively increasing radius of curvature.
[0067] According to some embodiments, the first convex arc segment S1 can extend for an
amplitude corresponding to a first angle α1, comprised for example between 110° and
150°, and can have a first radius of curvature R1 comprised between 5mm and 10mm.
In particular, the first radius of curvature R1 can be comprised between 6mm and 8mm.
For example the first radius of curvature R1 can be comprised between 6.8mm and 7.2mm.
[0068] According to other embodiments, the first convex arc segment S1 can extend for an
amplitude corresponding to a first angle α1, comprised between 120° and 140°, and
can have a first radius of curvature R1 which can be comprised for example between
6.9mm and 7.1mm.
[0069] According to other embodiments, the second convex arc segment S2 can extend for an
amplitude corresponding to a second angle α2, comprised for example between 50° and
70°, and can have a second radius of curvature R2 comprised between 25mm and 45mm.
In particular, the second radius of curvature R2 can be comprised between 30mm and
40mm.
[0070] According to other embodiments, the second convex arc segment S2 can extend for an
amplitude corresponding to a second angle α2, comprised between 55° and 65°, and can
have a second radius of curvature R2 comprised between 32mm and 37mm.
[0071] According to some embodiments, the third convex arc segment S3 can extend for an
amplitude corresponding to a third angle α3, comprised for example between 20° and
40°, and can have a third radius of curvature R3 comprised between 80mm and 130mm.
In particular, the third radius of curvature R3 can be comprised between 90mm and
120mm.
[0072] According to other embodiments, the third convex arc segment S3 can extend for an
amplitude corresponding to a third angle α3, comprised between 25° and 35°, and can
have a third radius of curvature R3 comprised between 100mm and 110mm, more particularly
it can be comprised for example between 104mm and 106mm.
[0073] According to some embodiments, the second convex arc segment S2 is tangent at one
end with the first convex arc segment S1 and at the opposite end with the third convex
arc segment S3, so that the profile 40 has a development without discontinuities.
[0074] According to other embodiments, it can be provided that each convex arc segment S1,
S2, S3 itself consists of a plurality of arc sub-segments, which in their entirety
approximate the respective arc segments S1, S2, S3. Each arc sub-segment has, with
respect to the previous segment (in the direction of the stream of air W) a progressively
decreasing amplitude and a progressively increasing radius of curvature.
[0075] For example, according to a possible embodiment, not shown, it can be provided that
instead of the first convex arc segment S1, two arc sub-segments are disposed one
after the other, and extend for respective amplitudes, for example with angles of
67° and 63°, and in which the respective radii of curvature can vary for example from
6.8mm to 7mm and from 7mm to 7.2mm.
[0076] According to some other embodiments, the curvature of the first convex arc segment
S1 cooperates with the channeling element 20 to define an exit passage 21 for the
stream of air.
[0077] According to other embodiments, the channeling element 20 can have an arched shape,
with a radius of curvature suitable to cooperate with the first arc segments to define
an exit passage 21 on each side of the median plane M.
[0078] According to some embodiments, the channeling element 20 can have a curvilinear profile,
which can be positioned above the portion of the external surface 22 in correspondence
with the longitudinal aperture 16.
[0079] In one embodiment, the channeling element 20 has a longitudinal development at least
equal to the extension of the longitudinal aperture 16.
[0080] In another embodiment, shown in fig. 2, the channeling element 20 has a vertical
development equal to the development of the main body 12.
[0081] In another embodiment, shown by way of example in fig. 4, the channeling element
20 can provide a separator element 24 configured to determine a separation substantially
into two halves of the stream of air W exiting from the longitudinal aperture 16.
[0082] According to some embodiments, the separator element 24 can have in section a triangle
or arrow shape, with an apex 24a facing toward the longitudinal aperture 16 and the
base facing toward the channeling element 20.
[0083] According to other embodiments, the separator element 24 can have concave sides,
arched toward the inside.
[0084] In some embodiments, the apex 24a can be rounded or beveled.
[0085] The presence of the separator element 24 allows to obtain a progressive reduction
in the transit section of the air, which is maximum in correspondence with the longitudinal
aperture 16, that is, on the apex 24a of the separator element 24, and is minimum
in correspondence with the end of the exit passage 21, that is, in correspondence
with the outermost end of the channeling element 20.
[0086] The reduction in section between the apex 24a of the separator element 24 and the
passage 21 can therefore determine an increase in the speed of the stream of air W
toward the outside and toward the front part of the fan 10.
[0087] In this way two streams of air W are created, with opposite directions, each of which,
exiting from a respective passage 21, adheres with a respective portion of the external
surface 22 of the main body 12, with the streams substantially combining again on
the front of the fan 10.
[0088] According to some embodiments, the passage 21 is conformed as a narrowing in section
for the passage of the stream of air W.
[0089] According to some embodiments, each passage 21 has a width comprised between about
0.1mm and 50mm.
[0090] According to some embodiments, the passage 21 has a width comprised between about
1mm and about 20mm.
[0091] According to other embodiments, the passage 21 has a width comprised between about
3mm and about 10mm.
[0092] The width of the passage 21 thus designed allows to supply a stream of air toward
the user with a speed suitable to confer on the user a sensation of optimum comfort
at the desired distance.
[0093] In particular, the speed of the stream of air at exit is such as to optimize both
the effectiveness of the functioning of the fan 10 and the comfort of the user.
[0094] According to other embodiments, the external surface 22 of the main body 12, at least
in correspondence with the zone affected by the longitudinal aperture 16, has a surface
finish suitable to eliminate, or at least reduce, possible wrinkles and roughness,
so as to prevent turbulence in the stream of air, thus guaranteeing a high level of
comfort for the user.
[0095] According to some embodiments, the external surface 22 can have a surface roughness
comprised between 0.001µ and 100 µ measured in terms of Ra, Rz and Rq.
[0096] According to one embodiment, preferably in a substantially front zone, that is, facing
toward the space to be conditioned or ventilated, the main body 12 can have interference
and diversion means 32, configured to cause a diversion of the stream of air W in
order to make its adherence to the external surface 22 at least partly terminate,
and/or to determine a jet of air to be modulated in amplitude, according to requirements.
[0097] The interference means 32 can be installed at any point whatsoever on the height
of the main body 12, to modulate the amplitude of the stream of air W and/or the jet
of air that hits the space where it is located.
[0098] According to some embodiments, the interference means 32 are the mechanical type.
[0099] According to some embodiments, for example described with reference to fig. 5, the
mechanical interference means 32 can comprise mechanical interference members 32a,
for example longitudinal fins, adjustable as desired, that is, having a shape similar
to that of the flaps of an airplane.
[0100] The mechanical interference members 32a can be configured as flaps, or moving surfaces
with a shape similar to the surface that supports them, and configured to deflect
the stream of air toward the outside.
[0101] According to some embodiments, the mechanical interference members 32a can be rotated
from a position substantially parallel to the external surface 22 of the main body
12 to a position substantially perpendicular thereto.
[0102] According to other embodiments, the interference means 32 are the aerodynamic type.
[0103] According to these embodiments, for example shown by way of example in fig. 6, aerodynamic
interference members 32b can be provided, such as nozzles, or shaped holes, which
generate jets of air with an angled direction with respect to the external surface
22, for example substantially perpendicular, to deflect or perturb the main stream
of air and cause it to be propagated in the space.
[0104] According to one embodiment, shown by way of example in fig. 2, the fan 10 can also
comprise a filtering element 26.
[0105] The filtering element 26 can be installed upstream of the air suction and distribution
unit 14 and in correspondence with the entrance holes 27, so that the air sucked in
can be suitably cleaned and purified of dust or particular allergens present in it.
[0106] The position of the filtering element 26 substantially at the top of the overall
structure of the fan 10 facilitates its access for possible maintenance and replacement
interventions, also thanks to the particular conformation of the main body 12.
[0107] According to another embodiment, shown by way of example in fig. 2, the fan 10 can
comprise a conditioning device 28 installed inside the main body 12 and in substantial
correspondence with the longitudinal aperture 16.
[0108] The conditioning device 28 can be any device whatsoever, able to modify the condition
of the stream of air W to supply a determinate effect inside the space where it is
emitted by the fan 10.
[0109] For example, the conditioning device 28 can supply heating, cooling or dehumidification
of the stream of air W, or also a combination of these in the case of a fan 10 designed
to perform diverse functions according to requirements.
[0110] The conditioning device 28 is installed, in the case shown here, upstream of the
channeling element 20.
[0111] According to one embodiment, shown by way of example in fig. 2, the conditioning
device 28 can be installed immediately upstream of the longitudinal aperture 16.
[0112] According to another embodiment, the conditioning device 28 can be installed downstream
of the longitudinal aperture 16.
[0113] According to embodiments described here, the fan 10 comprises a deflector device
34 provided with a plurality of deflector elements 35 to convey the stream of air
through the longitudinal aperture 16 and toward the channeling element 20.
[0114] According to another embodiment, shown by way of example in figs. 2 and 3, the fan
10 can comprise an adjustment device 36 which cooperates with the deflector device
34 to determine the desired orientation of the deflector elements 35, in order to
modulate the direction of the stream of air W.
[0115] In one embodiment, the adjustment device 36 can determine the rotation of the deflector
elements 35 from a position substantially parallel to the support base 18 to a position
substantially perpendicular to the support base 18.
[0116] According to another embodiment, shown by way of example in fig. 2, the fan 10 also
comprises a device 30 to rotate the main body 12.
[0117] The rotation device 30 can be installed in correspondence with two different portions
respectively of the main body 12 and the support base 18.
[0118] The rotation device 30 is provided with a kinematism that determines the rotation
of the main body 12 with respect to the support base 18 by a desired angle of rotation.
[0119] In this way the rotation device 30, when driven, for example remotely, by a button
or by any other known system, determines the movement of the main body 12 around an
axis, to determine its position or to drive a continuous rotation movement.
[0120] It is clear that modifications and/or additions of parts may be made to the fan 10
as described heretofore, without departing from the field and scope of the present
invention.
[0121] It is also clear that, although the present invention has been described with reference
to some specific examples, a person of skill in the art shall certainly be able to
achieve many other equivalent forms of fan, having the characteristics as set forth
in the claims and hence all coming within the field of protection defined thereby.

disposed in its rear zone, for the emission of a stream of air (W) toward the outside,
and also comprises an air suction and distribution unit (14), located, at least for
a substantial part thereof, above the beginning of said longitudinal aperture (16),
and a channeling element (20) positioned in proximity to said longitudinal aperture
(16) and cooperating with it to determine the exit of the stream of air (W) through
