Technical field
[0001] The present invention relates to a kit for installing an anti-odour filter in a hood
and to a domestic hood according to the preamble to claim 1, and also to a method
for installing an anti-odour filter in a domestic hood according to the preamble of
claim 12.
Background art
[0002] It is known to use both capturing and filtering hoods in kitchens of private homes,
restaurants, canteens or in any other environment in which there is a need to cook
food and then to evacuate the cooking fumes.
[0003] The anti-odour filter for such hoods is also known in the background art. For example,
an anti-odour filter of known type comprises a box-shaped body, generally parallelepiped-shaped.
The box-shaped body has a pair of opposite breathable surfaces, between which there
is defined a containment compartment for filtering material such as for example, activated
carbons or other elements capable of filtering the organic compounds (VOC) responsible
for spreading bad odours.
[0004] Disadvantageously, there is a large variety of hood models on the market.
[0005] For each model, there is a corresponding type of filter and in most cases, a filter
designed for a specific hood model cannot be used for another model. This generates
significant problems both for the consumer, who has difficulty finding the spare parts,
and for the distributors who need to stock up with a large number of types of filters.
[0006] In an attempt to mitigate this problem, solutions have been conceived in which the
filter is defined by a plurality of modular elements. In particular, document
EP 1 527 806 A1 to Pellegrini shows a modular filter of this type.
[0007] Disadvantageously, the modular filters already known provide making corresponding
hoods, which are to have a housing for the filter having sizes that are compatible
with the modules, that is to say having as a size a whole multiple of the corresponding
sizes of the modules. This is the case of the Pellegrini document which, in paragraph
36, teaches to shape a wall of the housing for the filter so as to be able to engage
with the modular elements defining the filter itself.
[0008] Alternatively, it is possible to use modules having different sizes for different
models of hoods already on the market. Thereby however, the advantage of the modularity
is at least partly lost.
[0009] To date, it is not possible to make a universal modular system, that is to say applicable
both to hoods already on the market and to the new models.
Object of the invention
[0010] In this context, the technical task at the basis of the present invention is to propose
a kit for installing an anti-odour filter in a domestic capturing hood which overcomes
the above-mentioned drawbacks of the known technique.
[0011] In particular, it is an object of the present invention to make available a kit for
installing an anti-odour filter in a domestic capturing hood capable of being used
with any type of hoods, including those already on the market.
[0012] The technical task identified and objects specified are substantially achieved by
a kit for installing an anti-odour filter in a domestic capturing hood comprising
the technical features explained in one or more of the appended claims.
Advantages of the invention
[0013] In particular, a first embodiment of the present invention relates to a hood comprising
a filter holder. Such filter holder has a seat configured to house a predetermined
number of modular elements.
[0014] Each modular element comprises a box-shaped body, which defines a containment compartment
for an absorbing element. The box-shaped body has a first and a second breathable
surface opposite to each other and permeable to air.
[0015] The box-shaped body comprises a first and a second edge substantially parallel to
each other. The first edge is configured to adhere to a second edge of another modular
element. Said second edge is configured to adhere to a first edge of another modular
element.
[0016] Optionally, the first edge has at least one male connector configured to be inserted
into a female connector of another modular element. The second edge has at least one
female connector configured to receive a male connector of another modular element.
[0017] Optionally, the seat of the filter holder has a first inner wall having at least
one female connector for receiving a male connector of a modular element. The seat
also has a second inner wall opposite to the first inner wall. The second inner wall
has at least one male connector to be inserted into the female connector of a modular
element.
[0018] A second embodiment of the invention relates to a kit for installing an anti-odour
filter in a hood. Such kit comprises an anti-odour filter comprising a predetermined
number of modular elements. The kit also comprises a filter holder having a seat configured
to house the anti-odour filter made starting from the modular elements.
[0019] A third embodiment of the invention relates to a method for installing an anti-odour
filter in a domestic hood. Such method comprises the steps of providing a predetermined
number of modular elements and of providing a domestic hood.
[0020] A filter holder is also provided, having a seat configured to house the anti-odour
filter.
[0021] Then, the predetermined number of modular elements is juxtaposed in such a manner
that a first edge of at least one modular element is adjacent to and in contact with
a second edge of another modular element and that a second edge is adjacent to and
in contact with a first edge of another modular element.
[0022] The first edge is therefore constrained to the second edge of another modular element,
while the second edge is constrained to the first edge of another modular element
by means of engagement means so as to make the predetermined number of modular elements
integral with one other and to assemble the anti-odour filter.
[0023] The anti-odour filter is then inserted into the seat of the filter holder and then
into the capturing hood. The devices and the method according to the invention resolve
the technical problem because they make possible a universal modular system adaptable
to any model of hood. Indeed, the user may autonomously assemble filters of different
sizes using an appropriate number of modular elements. To insert such filters into
existing hoods, it is sufficient to provide a filter holder having outer sizes compatible
with the hood model desired. The seat of the filter holder instead has sizes compatible
with the modular system.
[0024] Moreover, advantageously the use of male and female connectors allows holding the
edges of the modular elements in contact between one another, thus avoiding the creation
of a passageway for the air which, in addition to not being filtered, would increase
the noisiness of the hood.

DETAILED DESCRIPTION
[0026] Even when not expressly indicated, the individual characteristics described in reference
to the specific embodiments shall be intended as accessories and/or interchangeable
with other characteristics described in reference to other embodiments.
[0027] With reference to the accompanying drawings, 1 indicates a modular element for assembling
anti-odour filters 100 (Figure 4) for domestic hoods, both capturing or filtering
hoods.
[0028] The element 1 comprises a box-shaped body 2, which defines a containment compartment
3. Activated carbons (not shown) or any other absorbing/filtering element may be inserted
into the containment compartment 3 to perform a filtering action.
[0029] In particular, the box-shaped body 2 has a first 4 and a second breathable surface
5 opposite to each other and permeable to air. The box-shaped body 2 comprises a first
6 and a second edge 7 substantially parallel to each other. Further parallel edges
10 join the first 6 and the second edge 7. In particular, the further edges 10 are
perpendicular to the first 6 and to the second edge 7.
[0030] It is worth noting that the box-shaped body 2 preferably has the shape of an elongated
parallelepiped.
[0031] The prevailing size, or length, is defined along the development direction of the
first 6 and of the second edge 7. The depth, which is less than the length, is defined
along the development direction of the further edges 10. The height, which is less
than the depth, is defined along the direction perpendicular to the breathable surfaces
4, 5.
[0032] Therefore, in a preferred embodiment, the further edges 1 have a linear length which
is less than the linear length of the first 6 and of the second edge 7 so that the
box-shaped body 2 takes on a parallelepiped configuration with a rectangular base.
[0033] In further detail, it is worth noting that the first breathable surface 4 is defined
by a grid 11 made integral with the edges 6, 7 and preferably with the further edges
10.
[0034] Preferably, the second breathable surface 5 is defined by a breathable cloth 12.
Such cloth 12 is for example, associated with the edges 6, 7 by means of heat-sealing
and preferably with the further edges 10.
[0035] The first edge 6 is configured to adhere to a second edge 7 of another modular element
1. Similarly, the second edge 7 is configured to adhere to a first edge 6 of another
modular element 1.
[0036] In particular, the aforesaid edges 6, 7 of the respective modular elements 1 are
juxtaposed with respect to one another so that they are in surface contact with one
another.
[0037] Such surface contact is closed so as to avoid gaps between the respective edges 6
and 7, which are harmful for the filtering performance and for the noise caused by
the sucked air passing through such gaps.
[0038] Advantageously, this allows anti-odour filters 100 having different sizes to be formed
by assembling a predetermined number of modular elements 1 with one another.
[0039] The modular element 1 comprises constraining means which in a preferred embodiment,
are made integral with the respective edges 6, 7.
[0040] In the preferred embodiment, such constraining means comprise at least one male connector
8 and one female connector 9.
[0041] In detail, the male connector 8 is arranged on the first edge 6, while the female
connector 9 is arranged on the second edge 7.
[0042] The male connector 8 is configured to be inserted into the female connector 9 of
another modular element 1.
[0043] Similarly, the female connector 9 is configured to receive the male connector 8 of
another modular element 1. Such constraining means allow making a plurality of modular
elements 1 integral with one another.
[0044] According to the embodiment shown in Figures 1 and 2, the modular element 1 comprises
two male connectors 8 and therefore, two female connectors 9.
[0045] In alternative embodiments (not shown), there may be any number of connectors 8,
9, so long as the coupling is possible between the edges 6, 7 of different modular
elements 1.
[0046] Preferably, the number of male connectors 8 is equal to the number of female connectors
9. Preferably, the mutual spacing between the male connectors 8 and the distribution
thereof along the first edge 6 is equal to the mutual spacing between the female connectors
9 and the distribution of the female connectors along the second edge 7.
[0047] In further detail, each female connector 9 comprises a recess 13 made in the second
edge 7. The recess 13 has a bottom wall 14 parallel to the development direction of
the second edge 7. The recess 13 also has a pair of side walls 15 perpendicular to
the development direction of the second edge 7. The recess 13 also has an abutment
surface 16 which substantially lies on the same plane as the first breathable surface
4.
[0048] Similarly, each male connector 8 comprises a pair of fins 17 which protrude from
the first edge 6. Such fins 17 are configured to interfere with the side walls 15
of the recess 13. In particular, the fins 17 slightly diverge from one another so
that the insertion thereof into the recess 13 requires a slight forcing capable of
elastically deforming them. Once they are inserted into the recess 13, the fins 17
exert a pressure against the side walls 15.
[0049] Each male connector 8 also has a projection 18 which protrudes externally from the
first edge 6. Such projection 18 is arranged between the fins 17. Both the projection
18 and the fins 17 substantially develop along the whole height of the first edge
6. It is also worth noting that the projection 18 and the fins 17 are provided to
abut against the abutment surface 16 of the recess 13.
[0050] In an alternative embodiment (not shown in the drawings), the constraining means
materialize in mechanical joining members which are distinct and separate from the
respective edges 6 and 7. Such mechanical joining members are for example, shaped
like holding clips which engage the edges 6 and 7 of the respective modular elements
1 to make them integral with one another.
[0051] The modular element 1 comprises at least one reinforcing rib 19 placed in the containment
compartment 3.
[0052] Such rib 19 is connected to the first 6 and to the second edge 7.
[0053] In particular, such rib 19 is perpendicular to the edges 6, 7 and consequently, parallel
to the further edges 10.
[0054] In greater detail, the rib 19 is made integral with the edges 6, 7 and with the first
breathable surface 4.
[0055] Preferably, the modular element 1 comprises a plurality of parallel ribs 19 and even
more preferably, spaced at a same distance from one another.
[0056] A domestic hood 20 is also part of the present invention. In addition to having the
usual components required for the operation thereof and known to an expert in the
field, such hood 20 comprises a filter holder 21 which has a seat 22 configured to
house a predetermined number of modular elements 1 as described above.
[0057] In particular, the seat 22 is sized in such a manner as to house a predetermined
number of modular elements 1.
[0058] Figure 4 for example, shows that the seat 22 of the filter holder 21 may house six
modular elements 1 made integral with one another.
[0059] In greater detail, in the preferred embodiment, the seat 22 has a first inner wall
22a having at least one female connector 23 to be coupled with a shape coupling with
the male connector 8 of a modular element 1.
[0060] The seat 22 also has a second inner wall 22b, opposite to the first inner wall 22a,
and having at least one male connector 24 to be coupled with a shape coupling with
the female connector 9 of a modular element 1.
[0061] The connectors 23, 24 of the seat 22 are made in a similar manner to the connectors
8, 9 of the modular element 1.
[0062] It is worth noting that in order to facilitate the maintenance or replacement operations
of the filter elements, the filter holder 21 may be removed from the hood 20, taking
with it the modular elements 1.
[0063] In use, the air that flows inside the hood 20 passes through the modular elements
1 inserted in the filter holder 21 since there are no gaps between the various modular
elements, in particular the sucked air passes through the first 4 and the second 5
breathable surfaces.
[0064] The air is then purified by a filter element, generally activated carbon, placed
inside the containment compartment 3.
[0065] To proceed with the installation of the anti-odour filter, that is with a predetermined
number of modular elements 1 made integral with one other, it is worth pointing out
that the containment compartment 3 of each module of the aforesaid modules 1 in the
hood 20 was already filled with the activated carbons by the manufacturer, just as
the manufacturer already executed the heat-sealing process of the cloth 12 to the
edges 6, 7 of the second breathable surface 5.
[0066] Therefore, the user who wants to install an anti-odour filter 100 in a domestic hood
20 is required to perform a step of juxtaposing the predetermined number of modular
elements 1 such that the first edge 6 is adjacent to and in surface contact with the
second edge 7 of another modular element 1 and such that said second edge 7 is adjacent
to and in contact with a first edge 6 of another modular element 1.
[0067] Such step is to be repeated as many times as there are modular elements 1 requiring
coupling with one another.
[0068] The user then must perform a step of constraining the first edge 6 to the second
edge 7 of another modular element 1 and the second edge 7 to the first edge 6 of another
modular element 1 by means of engagement means so as to make the predetermined number
of modular elements integral with one other.
[0069] Finally, the user is to perform a step of inserting the predetermined number of modular
elements made integral with one another into the seat 22 of the filter holder 21,
and a step of inserting the filter holder 21, bringing with it the predetermined number
of modular elements made integral with one another, into the hood 20.
[0070] Should it be necessary to perform an operation of replacing the filter element, there
is provided a step of accessing inside the hood 20 by means for example, of removing
the grease filter grids (not shown in the drawings), and therefore removing the filter
holder 21 from which to remove the modular elements therein installed.

may make several modifications and variants to the configurations described above.
