Technical field
[0001] The present invention relates to a suction hood for household environments, according
to the preamble of claim 1.
[0002] Particularly, but not exclusively, the present invention relates to a hood integrated
in a stove, commercially known as down-draft hood.
Background of the invention
[0003] Household hoods are now installed in all kitchens in homes, as their usefulness,
in the suction of gases due to food preparation, is today undisputed.
[0004] Therefore, it is becoming increasingly important to have hoods for household environments
that are effectively able to eliminate the fumes produced when cooking food.
[0005] Hoods have been developed for this purpose which can both suction and discharge outside
the home, through a suction unit, the air sucked to filter it and then re-enter it
in the house.
[0006] To that end, a fume discharge conduit is provided downstream of the forced suction
unit, i.e. at the outlet thereof, which for example allows making the cooking fumes
and steam sucked pass therein and discharge them, for example outside of the house.
[0007] Clearly, during filtration, the air taken must be subjected to the action of one
or more filters that have the function of purifying the gases sucked.
[0008] The filters usually installed in a hood can for example be specific for filtering
the grease or reducing unpleasant smells present in the gases.
[0009] Grease filters normally consist of a metal grid and are located upstream of the forced
suction unit while odor filters normally consist of a filtering element comprising
activated carbon and are usually arranged downstream of the suction unit and preferably
within the path defined by the fume discharge conduit.
[0010] However, in the hoods currently available on the market, the filters arranged in
the fume discharge conduits have a filtering efficiency lower than would their nominal
value be, due to losses that occur along such a fume discharge conduit.
[0011] This is due to the fact that paths for the gases are created in known fume discharge
conduits which have a lower resistance than the passage through the filters, so as
to affect the filtering capacity of the gases sucked.
[0012] It should also be noted that these filters, be they grease or odor ones, require
periodic maintenance to be washed, fixed or regenerated and ensure the effective functioning
thereof.
[0013] These maintenance operations must be able to be carried out by the user without the
intervention of specialized personnel.
[0014] However, known hoods have the need of removing or taking away panels to access the
compartment where said filters are arranged.
[0015] This operation is exceedingly burdensome for odor filters since they are arranged
downstream of the suction unit outlet and can therefore be reached with greater difficulty.
[0016] This problem is particularly felt in the so-called down draft hoods, in which the
odor filter extraction involves the disassembly of several elements of the hood and
in some cases even of parts of the kitchen cabinet which houses the hood itself.
[0017] This is due to the fact that down draft hoods are usually integrated into the hob
or in the top of the kitchen cabinet.
[0019] Documents
US 4411254 and
US 2012/204855 describe ventilation and filtration systems where odor filters arranged downstream
the ventilation units can be extracted frontally from a kitchen cabinet. Moreover,
document
US 2013340742 describes a kitchen hood where a grease filter upstream the ventilation unit can
be removed from the side of the cooktop, but no filters downstream the ventilation
unit are provided.
[0020] In this context, the technical task at the basis of the present invention is to provide
a hood for household environments which allows improving the filtering performance
as well as ensuring an easier maintenance of the filters, particularly of the filters
arranged downstream of the forced suction unit.
[0021] In particular, the object of the present invention is to provide a hood for household
environments that is more efficient in terms of filtering and that is easier to maintain.
SUMMARY OF THE INVENTION
[0022] According to the present invention, the above technical task and the specified objects
are achieved by a hood for household environments according to one or more of the
claims below.
Advantages
[0023] A hood for household environments can be obtained by the present invention which
is more efficient from the point of view of the filtering action of the gases sucked.
[0024] The present invention allows providing a hood for household environments which exhibits
great ease of maintenance.
[0025] In addition, by the present invention, in a down-draft hood it is possible to remove
the filters from the same side where the elements necessary for cooking food are provided,
thereby improving the hood in terms of ergonomics and allowing the use of the space
below the top also for an oven or other fixed installation.
[0026] This implies that the maintenance operations should be simple so as to prevent the
user from giving up maintenance for difficulty or laziness.

DETAILED DESCRIPTION
[0028] Although not explicitly mentioned, the single features described with reference to
the specific embodiments shall be considered as ancillary and/or interchangeable with
other features, which are described with reference to other exemplary embodiments.
[0029] A hood for household environments according to the present invention is globally
indicated with reference numeral 1 in the figures.
[0030] Hood 1 comprises a containment frame 2, preferably made of metal material with any
decorative parts made of plastic.
[0031] By the term containment frame, in the context of the present invention, it is meant
a structural element designed to contain devices adapted to the functioning of the
hood (as will be better explained hereinafter) including shaped elements and/or cover
panels that give the hood a particular aesthetic shape.
[0032] By way of example, the hood in figures 2 to 7B has a frame structure 2, different
in shape from the one shown in figure 1.
[0033] Frame 2 of hood in figure 1, in fact, is intended to be fixed to a wall in an area
of the same located above a hob having one or more burners. Such a frame is mainly
adapted to be used in the so-called inverted T hoods or more generally in box and
decorative hoods, that is, all those which have a compartment within which the structure
is accommodated.
[0034] By contrast, frame 2 of the hood shown in figures 2 to 7B is intended to be integrated
in or associated with a hob so that the functional components of the hood (including
the suction unit, filters, fume discharge chimney, control elements, etc.) and of
the hob (including heating means, electrical and electronic circuits, electronic control
unit, etc.) may be associated with a top or a kitchen cabinet to obtain what is commonly
known as concealed or down-draft hood.
[0035] For the latter type of configuration, it should be noted that hood 1 is configured
to generate a cross current higher than the rising current of the cooking steam, so
that such a steam is sucked towards the hob itself.
[0036] Hereinafter, in the present description, irrespective of whether it is the hood shown
in Figure 1 or of the embodiment of the hood shown in Figures 2 to 7B, frame 2 comprises
a first opening 3, preferably located in a top area of the frame, and at least a second
opening 4, preferably located on a different portion of the containment frame 2.
[0037] Hood 1 comprises a forced suction unit 5 comprising a conveyor 5a, for example shaped
as a screw, defining a suction section 5b, delimited by a grid 5c which can be traversed
by the aspirated gases, an outlet 5d in fluid communication with a fume discharge
conduit 14 and a further closing grid 5e.
[0038] In order to discharge the gases produced during the preparation/cooking of food,
the first opening 3 is intended to be engaged by the fume discharge conduit 14 while
the second opening 4 is in fluid communication with the suction section 5b.
[0039] The forced suction unit 5 is for example a fan (axial or centrifugal) 5f, i.e. an
electrical operating machine provided with an impeller able to withdraw air from a
suction zone, in the vicinity of the food cooking area, and deliver it to an outlet.
[0040] It should be noted that the fan (axial or centrifugal) 5f is arranged within the
volume defined by conveyor 5a.
[0041] In particular, the first opening 3 and the second opening 4 are intended to be both
in fluid communication for the discharge of the cooking fumes to the outside of the
house (for example through a chimney), so as to implement a so-called suction configuration
(air discharged outside the room where hood 1 is placed) or a filtering configuration
(air fed back into the room properly filtered).
[0042] Hood 1 also comprises at least one filter 6a, 6b where the at least one filter 6a,
6b is operatively placed in fluid communication between the first opening 3 and the
second opening 4 of frame 2 of hood 1.
[0043] In the preferred embodiment, hood 1 comprises two filters 6a and 6b, each of which
has different filtering properties, and at least one filter holder compartment 8a,
8b, preferably two filter holder compartments as will be described hereinafter.
[0044] According to a preferred embodiment, hood 1 comprises two filter holder compartments
8a, 8b and two filters 6a and 6b, i.e. one compartment for each filter 6a and 6b.
[0045] In particular, filters 6a and 6b are mutually placed operatively in series with respect
to an input air flow in the suction section 5b of the forced suction unit 5.
[0046] "Operatively in series" means, in the context of the present invention, the inlet
air flow in the suction section 5b of the suction unit 5 first passes through filter
6a and then through filter 6b.
[0047] Preferably, hood 1 comprises two filters 6a and 6b placed operatively in series,
and in particular, a grease filter 6a and an odor filter 6b operatively placed downstream
of the grease filter.
[0048] The grease filter 6a is a metal grid filter.
[0049] Odor filter 6b means a filter capable of capturing and retaining the odors produced
by cooking, for example by means of an active carbon filter.
[0050] In particular:
- the grease filter 6a is placed operatively upstream of the suction section 5a and
is directed towards the hob, when hood 1 is in use, as exemplified in figure 1, or
it lies in a portion of the hob when hood 1 is in use, as exemplified in figures 2
to 7B;
- the odor filter 6b is operatively placed downstream of outlet 5d, i.e. downstream
of the first opening 3, and is directed towards the outside, when hood 1 is in use,
as exemplified in figure 1, or lies in a portion of the hob when hood 1 is in use,
as exemplified in figures 2 to 7B.
[0051] In Figure 1 it is noted that the odor filter 6b is, for example, made by implementing
a single filtering element while in Figures 3 and 7B, the odor filter is made by using
three separate filtering elements.
[0052] It is noted that hood 1 is able to function even in the absence of one or more filters
6a, 6b.
[0053] Advantageously, hood 1 comprises a first filter holder compartment 8a arranged to
hold the at least one filter 6a, 6b, preferably, the odor filter 6b.
[0054] The first filter holder compartment 8a is arranged between outlet 5d of the forced
suction unit 5 and the fume discharge conduit 14.
[0055] Such a filter holder compartment 8a defines, also with reference to Figures 5 and
5A, a bottom 22 and a top 23 connected together by means of respective pairs of opposite
side walls 24, 25, where top 23 defines an opening 21.
[0056] Such a filter holder compartment 8a is for example made of plastic material or, preferably,
metal.
[0057] According to one aspect, hood 1 comprises a closure 9 to close opening 21 of the
filter holder compartment 8a being movable between:
- a first position in which the at least one filter, such as that identified with 6b
in the accompanying Figures, is accessible through such an opening 21 to allow the
removal thereof from the filter holder compartment itself, and
- a second position in which the closure 9 provides a tight seal of opening 21 of the
filter holder compartment 8a between outlet 5d of the forced suction unit 5 and the
fume discharge conduit 14.
[0058] In this first position, closure 9 is at least partly, preferably completely, distanced
from opening 21 of the first filter holder compartment 8a in such a way that filter
6a, 6b faces towards the external environment to the containment frame 2 to allow
the removal of the filter itself from the filter holder compartment 8 (figure 1 and
figures 7A and 7B).
[0059] This makes it possible to extract the at least one filter 6a, 6b from the first filter
holder compartment 8a so as to remove it from the same and proceed to the cleaning
and/or regeneration and/or replacement of the exhausted filter, thus restoring the
full functionality of hood 1.
[0060] According to one aspect, the extraction of the at least one filter 6a, 6b from the
first filter holder compartment 8a is carried out manually by the user's intervention.
[0061] To this end, appropriate mechanical or magnetic aids are provided (not shown in the
figures) such as, for example, an extraction band required to facilitate the extraction
(and insertion) of the at least one filter 6a, 6b from/into the first filter holder
compartment 8a.
[0062] In an alternative embodiment, the mechanical or magnetic aids of the invention comprise
a low-voltage electric motor (not shown) which transmits motion through a kinematic
chain to the at least one filter 6a, 6b.
[0063] It is also noted that the transition from the first to the second position of closure
9 of the first filter holder compartment 8a does not require disassembly of parts
of the containment frame 2, being therefore a procedure directly activated by an unskilled
user.
[0064] It should also be noted that, in the second position of closure 9 (i.e. in the hermetically
sealed configuration), the phenomenon of losses that take place along the fume discharge
conduit 14 is prevented.
[0065] This depends on the fact that in hood 1, along the path that goes from outlet 5d
of the forced suction unit 5 to the discharge of the fumes, no paths are created for
the gases with lower resistance since closure 9 produces a hermetic seal for the gaseous
stream passing through the first filter holder compartment 8a.
[0066] This ensures that a part of the flow of gases sucked through filters 6a, 6b is dispersed
into the environment surrounding hood 1 without being filtered; therefore, the reintroduction
of odors caused by cooking in the room where the hood is placed is prevented.
[0067] With the solution just described, hood 1 achieves a filtration efficiency higher
than conventional hoods since the entire gas flow sucked by the suction unit passes
through the at least one filter 6a, 6b.
[0068] This is also achieved due to the fact that, in the second position of closure 9,
a seal is formed between closure 9 and the fume discharge conduit that ensures few,
if not absent, paths with lower resistance than the predetermined path for the discharge
of the gases themselves.
[0069] In addition to the foregoing, hood 1, whether the one shown with reference to Figure
1 or that shown with reference to Figures 2 to 7B, provides for the first filter holder
compartment 8 to comprise an under-frame 9a configured to removably hold said filter
6b.
[0070] Such under-frame 9a is preferably made of a plastic material, i.e. a nylon polymer
charged with suitable particles of glass, ceramics or other minerals in order to ensure
the proper resistance to temperatures that are achieved during the transit of the
gases sucked by the suction unit 5 of hood 1.
[0071] It should also be noted that the first filter holder compartment 8a is also removably
constrained to the containment frame 2 of hood 1 in a first portion of the same.
[0072] In particular, as can be seen in the Figures, the first filter holder compartment
8a is accessible by a user when the hood is installed since it faces towards the side
visible from the user (figure 1 and 3).
[0073] According to one aspect, the first filter holder compartment 8a includes extraction
members (not visible in the figures) for moving closure 9 between the first and the
second position.
[0074] These extraction members comprising, for example, a user interface such as a knob
10a (figure 1) or screws 10b (figures 7A and 7B).
[0075] According to one aspect, hood 1 comprises a second filter holder compartment 8b designed
to contain a further filter, such as the one identified with reference numeral 6a,
in the accompanying Figures, and such a second filter holder compartment 8b is arranged
between the second opening 4 of frame 2 and the suction section 5b of the forced suction
unit 5.
[0076] As can be seen in the Figures, the second filter holder compartment 8b is arranged
within the containment frame 2 and, in particular, in the vicinity of opening 4 of
the containment frame 2.
[0077] Such a second filter holder compartment 8b is configured to preferably accommodate
the grease filter 6a while the odor filter 6b is arranged in the first filter holder
compartment 8a.
[0078] With this provision of the filter holder compartment 8a and 8b, the two filters 6a
and 6b are arranged so that the gases are first filtered by the grease filter 6a and
then by the odor filter 6b without any paths with lower resistance along the way.
[0079] According to one aspect, with reference to the embodiment shown in figures 2 to 7B,
the second filter holder compartment 8b comprises a pit 8c (Figure 5A) which serves
as a seat for any collection of liquids or fluids that may overflow from the dishes
while cooking the food.
[0080] It should be noted that filter 6a is preferably shaped to mate with the pattern of
pit 8c in order to effectively exploit the volume of the pit itself.
[0081] It should be noted, with particular reference to figure 6, that the forced suction
unit 5 is arranged in a portion of frame 2 different from the one in which pit 8c
of the second filter holder compartment 8b is formed. In particular, the forced suction
unit 5 is offset with respect to such a pit 8c.
[0082] Such an asymmetrical arrangement of pit 8c and filter 6a with respect to the axis
of symmetry of the forced suction unit 5, in case of liquid or the like dropping,
advantageously prevents them from directly impinging motor 5f and thus prevents the
need of using watertight motors.
[0083] It should also be noted, again with reference to Figure 6, that the fluid connection
between outlet 5d of the forced suction unit 5 and the first filter holder compartment
8a is implemented by means of screw 5a.
[0084] According to one aspect, the second filter holder compartment 8b is constrained to
the containment frame 2 in a portion of the same accessible by a user when the hood
is installed.
[0085] In particular, a protection grid 13 is provided, removably associated with the second
filter holder compartment 8b, to protect filter 6a from any items that may be sucked
in due to the transverse current generated by the forced suction unit 5 when hood
1 is in use.
[0086] With reference again to figures 2 to 7B, hood 1 comprises a cover element 11 for
covering closure 9 of the filter holder compartment 8a (figures 2 and 3); this cover
element 11 is constrained to the containment frame 2 in a portion of the same that
is accessible by a user when hood 1 is installed.
[0087] In particular, such a cover element 11 is configured in such a way as to be movable
between a first position (Figure 2) in which closure 9 of the first filter holder
compartment 8a is concealed and a second position (Figure 3) in which such a closure
9 is made accessible to the user.
[0088] To this end, the cover element 11 comprises mechanical constraint means operatively
associated with the containment frame 2 to switch such a cover element between the
first and the second position, and vice versa.
[0089] For example, the mechanical constraint means comprise a pivot/hinge mechanism or
the like by which door 9 of the filter holder compartment 8a can be made accessible.
[0090] Such a pivot/hinge mechanism allows rotates the covering element 11 about an axis
of rotation X-X (figure 3).
[0091] Again, with reference to figures 2 to 7B, hood 1 further comprises a containment
body 12 for hold the filter holder compartments 8a and 8b, where Figures 2-4 show
the containment body 12 of the hood in figure 2 when constrained to frame 2 while
figures 5, 7A, and 7B show it removed from frame 2.
[0092] It should be noted that the containment body 12 comprises a hob 12a associated with
the containment frame 2, which defines a work surface or cooking area divided into
a plurality of zones 12b intended to receive respective dishes for cooking the food.
[0093] Such a hob 12a comprises heating means 12c for heating said plurality of zones 12b
intended to receive respective dishes for cooking food.
[0094] It should be noted that such plurality of zones 12b intended to receive respective
dishes for cooking food, are those zones in which the heat produced by the heating
means 12c spreads.
[0095] It should be noted that other zones 12d, 12d' of the hob different and separate from
the plurality of zones 12b intended to receive respective dishes for cooking food
are not impinged or do not receive the heat produced by the heating means 12c.
[0096] In one embodiment, hob 12a is a pane of glass and the heating means 12c are magnetic
induction plates or electric resistors.
[0097] According to one aspect of hood 1 shown in Figures 2 to 7B, the cover element 11
of closure 9 of the first filter holder compartment 8a is arranged in the work surface
where foods are prepared and particularly in a zone 12d not heated by the heating
means 12c.
[0098] In other words, the cover element 11 lies in the same plane in which food is prepared.
[0099] According to one aspect of hood 1 shown in Figures 2 to 7B, the cover element 11
of closure 9 of the filter holder compartment 8a is arranged in the work surface where
foods are prepared and particularly in a zone 12d not heated by the heating means
12c.
[0100] According to one aspect of hood 1 shown in Figures 2 to 7B, the odor filter 6b is
arranged in the vicinity of the work surface where food is prepared and in particular
in zone 12d not heated by the heating means 12c.
[0101] Advantageously, also the protection grid 13 is arranged in the same work surface
of the hob but in another zone 12d' not heated by the heating means 12c.
[0102] Therefore, in hood 1 shown in the Figures 2 to 7B, the filter holder compartments
8a and 8b and the respective filters 6b and 6a are facing towards the same work surface
or cooking area of food.
[0103] This allows removing filters 6a and 6b from the same side where the elements necessary
for cooking food are, where typically in down draft hoods the grease filters 6a are
removable from top for cleaning while the odor filters 6b are replaced by extracting
them from below.
[0104] Advantageously, having arranged the filter holder compartments 8a and 8b and filters
6a and 6b on the same surface where zones 12b intended to receive respective dishes
for cooking food are defined, this improves hood 1 in terms of ergonomics as it makes
the maintenance of filters 6a and 6b easy also for the user without the need for specialized
technical personnel.
[0105] In other words, due to the fact that the filter holder compartments 8a and 8b and
filters 6a and 6b lie on the same surface where zones 12b intended to receive respective
dishes for cooking food are defined, hood 1 shown in Figures 2 to 7B allows the advantage
over conventional down draft hood not to have occupied space above hob 12a, especially
in the island configuration.
[0106] By contrast, for hood 1 shown in Figure 1, the containment body (not shown) is preferably
removably constrained to the containment frame 2 in a portion thereof operatively
located upstream of the suction section 5b of the forced suction unit 5.
[0107] In hood 1 shown in Figure 1, the filter holder compartments 8a and 8b and filters
6a and 6b are facing towards a front wall of the containment body always accessible
by the user.
[0108] This allows removing filters 6a and 6b without having to remove elements of hood
1, making the maintenance of these filters easy also for the user without the need
for specialized technical personnel.
