Description

Technical area

[0001] The present invention, as preambled to claim 1, relates to an extractor hood useful in the field of kitchen equipment.

[0002] The present invention, according to the introduction of claim 10, also relates to an integrated kitchen cabinet containing the aforementioned extractor hood and useful in the field of kitchen equipment. State of the art

[0003] Suspended extractor hoods have been around for a long time, i.e. devices for extracting cooking fumes emanating from a hob below.

[0004] These extractor hoods have a first body defining an extraction opening facing the hob and is thus exposed to the rising flow of cooking fumes coming from this hob.

[0005] In use, an extraction group arranged in a special second box body located above the first body and fluid-dynamically connected by an exhaust duct via an extraction opening creates an extraction flow through the extraction opening which attracts the rising cooking fumes.

[0006] Before being discharged, the exhaust stream containing the cooking fumes is conveniently filtered through a filter assembly located in the first body directly above the extraction opening. This filter assembly is configured to filter grease and / or odors in the intake stream, allowing the exhaust stream to be recirculated back into the kitchen (filter hood) or to the outside environment (extractor hood), depending on the hood's configuration.

[0007] In addition to the hood covers, it is known in the art to integrate these hoods into special kitchen furniture for food storage. This furniture therefore has both aesthetic and functional value.

[0008] To meet the storage needs of larger families and offer kitchens with good capacity in a smaller space, kitchen manufacturers are increasingly interested in increasing the number and volume of compartments for storing food and cookware.

[0009] For this purpose, C-shaped extractor hoods have been developed, in which the exhaust duct, which fluid-dynamically connects the extraction opening to the extraction unit, is located near the bottom wall of the kitchen cabinet. This duct is characterized by an extension suitable for arranging the first and second bodies in opposite sections of the kitchen cabinet along the vertical direction, in particular near the lower and upper parts of the kitchen cabinet, respectively.

[0010] It is therefore obvious that C-shaped extractor hoods make it possible to obtain a large storage space in the central area of ​​the unit - that is, between the first and second body - in which to store food and / or cookware.

[0011] However, it should be noted that for the same extension of the furniture along the height direction, the smaller the thickness of the first and second body in the height direction, the larger the central bearing area.

[0012] A disadvantage of conventional extractor hoods is that the thickness of the first body in the vertical direction cannot be significantly reduced due to the arrangement of the extraction group just above the extraction opening. This arrangement of the filter group therefore sets a limit for the minimum thickness of the first body in the vertical direction, which cannot be reduced.

[0013] In the prior art, some extractor hoods are known which have at least part of the filter group arranged in the second body in front of the extraction group.

[0014] However, it should be noted that the second body is difficult for the user to access and reach due to its significantly elevated position relative to the footplate. Thus, the placement of the filter assembly in the second body significantly complicates regular maintenance / replacement of the filter assembly. Purpose of the invention

[0015] In this context, the task of the technician underlying the present invention is to propose an extractor hood for the extraction of cooking fumes and a kitchen cabinet integrating this extractor hood, which overcome the disadvantages of the above-mentioned known technology.

[0016] In particular, it is an object of the present invention to provide an extractor hood for the extraction of cooking fumes which not only allows for easy and quick replacement / maintenance of the filter group, but is also capable of maximising the storage volume of the kitchen cabinet in which it is integrated.

[0017] The purpose of the present invention is also to provide a kitchen cabinet with an integrated extractor hood that is both spacious and practical in use. SUMMARY OF THE INVENTION

[0018] According to the present invention, the stated technical problem and the specified purposes are achieved by an extractor hood for extracting cooking fumes and by a kitchen cabinet integrated into this extractor hood according to one or more of the following claims.

[0019] In particular, the present invention proposes to arrange the filter group at least partially in the exhaust air duct along the height direction.

[0020] In this way, it is possible to free the extension of the first body along the height direction from the physical space requirements of the filter group.

[0021] Thus, the present invention enables maximizing the storage capacity of the kitchen cabinet in which the range hood is integrated by reducing the thickness of the first body along the height direction.

[0022] It should also be noted that the filter group, since it is at least partially located in the exhaust air duct, is easily accessible and can be removed / installed via the extraction opening. LIST OF ILLUSTRATIONS

DETAILED DESCRIPTION

[0024] With reference to the attached figures, the present description relates to an extractor hood 1 for extracting cooking fumes, which can be integrated into a kitchen cabinet 100.

[0025] It should be noted that the extractor hood 1 which is the subject of this description is of the wall-mounted or under-wall type, that is to say it is configured to be mounted above a cooking surface 200 along the direction of natural rise of cooking fumes.

[0026] With particular reference to Fig. Both the extractor hood 1 and the kitchen cabinet 100 extend along a height direction ZZ (recognizable by the natural upward direction of the cooking vapors), a width direction XX, and a depth direction YY, which define a three-dimensional, in particular three-dimensional Cartesian, reference system. This means that the height directions ZZ, the width directions XX, and the depth directions YY are aligned perpendicularly to one another.

[0027] The kitchen cabinet 100 comprises a main body 101 defining an internal cavity 102 suitable for accommodating the extractor hood 1 and for storing any supplies and / or cookware in the remaining space.

[0028] Said cavity 102 extends along the height direction ZZ between a lower region 102a and an opposite upper region 102b, spaced from a central region 102c.

[0029] With reference to Fig. When the kitchen cabinet 100 is installed above a cooking hob 200 along the height direction ZZ, the lower portion 102a is aligned with the top of the cooking hob 200, so that it is flooded by the flow of cooking vapors rising from the hob during use. The kitchen cabinet 100 is therefore a wall-mounted cabinet.

[0030] The cavity 102 also extends along the width and depth directions XX and YY and thus takes on a three-dimensional shape.

[0031] In detail, the main body 101 has a plurality of side walls 101a, 101b, 101c that delimit the cavity 102 along the width direction XX and the depth direction YY.

[0032] In the Fig. In the embodiment shown, the side walls 101a, 101b, 101c delimit the cavity 102 on at least three sides.

[0033] Preferably, there are at least three side walls, two of which, 101b, 101c (flanks of the main body 101), are opposite one another along the width direction XX and a third wall, 101a (bottom wall of the main body), which extends along the width direction XX and connects to the other two, 101b, 101c, at opposite parts.

[0034] Each side wall 101a, 101b, 101c extends along the height direction between the lower region 102a and the upper region 102b.

[0035] In the Fig. In the embodiment shown, the kitchen cabinet 1 also comprises an upper wall 101d that delimits the cavity 102 along the height direction ZZ above. This upper wall 101 thus delimits the upper region 102b of the cavity 102 along the height direction ZZ.

[0036] Also with reference to the embodiment in Fig. the upper wall 101d is connected to the side walls 101a, 101b, 101c and thus defines the ceiling of the cavity 102.

[0037] The main body 101 may also comprise a support wall 100e arranged in the lower region 102a and extending along the width direction XX by connecting two opposite side walls - for example, the side walls referred to above as the flanks 101b, 101c of the main body 101.

[0038] According to one aspect, the support wall 100e is opposite the upper wall 101d along the height direction ZZ.

[0039] Preferably, the support wall 100e delimits the lower region 102a at the top and the middle region 102c of the cavity 102 at the bottom.

[0040] Advantageously, the support wall 100e defines, in addition to the structural rigidity of the main body 101 of the kitchen cabinet 100, a support surface for any supplies and / or cookware that may be present in the cavity 102.

[0041] The extractor hood 1, which is the subject of this description, is designed such that it can be integrated into the kitchen cabinet 100, in particular into the aforementioned cavity 102, along the height direction ZZ.

[0042] The extractor hood 1 comprises, with reference to the Fig. a first and a second body 2, 3, which are present in opposite sections of the kitchen cabinet 100 along the height direction ZZ.

[0043] According to one aspect, the first body 2 is present in the lower region 102a of the cavity 102, while the second body 3 is present in the upper region 102b of the cavity 102.

[0044] The first and second bodies 2, 3 are thus spaced apart in the height direction ZZ from the central region 102c of the cavity 102. The central region 102c is designed in the same way as the storage region of the cavity 102, i.e., that section of the cavity 102 that is suitable for accommodating food and / or cooking utensils.

[0045] In detail, the first body 2 defines an extraction opening 20 of the cooking fumes, that is to say an opening through which the extractor hood 1 is configured to extract the cooking fumes to be treated from the cooking surface below.

[0046] Referring to Fig. The extractor hood 1 is configured to arrange the first body 2 above the cooking surface 200 along the height direction ZZ, so that the extraction opening 20 faces the cooking surface. The extractor hood 1 is thus a wall-mounted or under-wall-mounted type hood.

[0047] The second body 3 has a box-shaped configuration defining an internal volume 30 suitable for accommodating a suction group 5. Further details on the suction group 5 are provided in a subsequent part of the description.

[0048] Preferably, the second body 3 extends predominantly in the width direction XX and in the depth direction YY.

[0049] The second body 3 is spaced apart from the first body 2 along the height direction ZZ. In particular, when the extractor hood 1 is integrated into the kitchen cabinet 100 with the first body 2 in the lower region 102a, the second body 3 is configured to be arranged in the upper region 102b of the cavity 102, preferably in contact with or near the upper wall 101d.

[0050] According to an alternative embodiment to that shown in the attached figures, when the extractor hood 1 is integrated into the kitchen cabinet 101, the second body 3 closes the cavity 102 at the top, thus de facto replacing the upper wall 101d of the wall cabinet 101, which can therefore be devoid of this component.

[0051] The extractor hood 1 further comprises an exhaust air duct 4, which extends predominantly along the height direction ZZ, fluid-dynamically connecting the first and second bodies 2, 3 and the internal volume 30 to the extraction opening 20.

[0052] In use, when the extraction group 5 (described below) is activated, the exhaust duct 4 conveys an extraction flow containing the cooking vapors from the extraction opening 20 of the first body 2 to the internal volume 30 of the second body 3.

[0053] It should be noted that the extension of exhaust air duct 4 along the height direction ZZ defines the corresponding position of the first and second bodies 2, 3 along the same direction. In other words, the extension of exhaust air duct 4 along the height direction ZZ enforces the distance of the first body 2 from the second body 3 along the height direction ZZ.

[0054] According to one embodiment, the exhaust air duct 4 of the extractor hood 1 is designed such that its extension along the height direction ZZ can be adjusted such that the first and second bodies 2, 3 can be arranged at different distances along the height direction ZZ depending on the extension of the kitchen cabinet 100 in this height direction ZZ.

[0055] Therefore, the exhaust air duct 4 is preferably designed to extend along the height direction ZZ and is calculated so that the corresponding position of the first body 2 relative to the second body 3 changes along the same direction ZZ in order to adapt to the geometric characteristics of the kitchen cabinet in which it is integrated.

[0056] In the Fig. shown and in Fig. In the embodiment explained in more detail, the exhaust air duct 4 comprises a first section 41 and a second section 42, which are telescopically connected along the height direction ZZ.

[0057] It should be noted that in the context of the present invention, the adjective “telescopic” means that the first and second sections 41, 42 of the exhaust air duct 4 are slidably inserted into one another along the height direction ZZ.

[0058] Due to the mutual sliding of the first and second sections 41, 42, the extension of the exhaust air duct 4 along the height direction ZZ and thus the mutual position of the first and second bodies 2, 3 along the same direction change.

[0059] Also with reference to the Fig. In the embodiment shown, the first and second sections 41, 42 extend - preferably predominantly - along the height direction ZZ.

[0060] In particular, according to one aspect, the first section 41 extends along the height direction ZZ between a first end 41a connected to the first body 2 and a first connecting end 41b; while the second section 42 extends along the height direction ZZ between a second end 42a connected to the second body 2 and a second connecting end 42b.

[0061] The first and second sections of the connecting ends 41b, 42b are thus slidably inserted into one another along the height direction ZZ, so that by varying the length of their overlapping section, the distance between the first end 41a of the first section 41 and the second end 42a of the second section 42 can be varied. Thus, by varying the length of the overlapping section of the first and second connecting ends 41b, 42b, it is possible to influence the distance between the first and second bodies 2, 3 along the height direction ZZ in order to adjust it depending on the geometric properties of the kitchen cabinet 100.

[0062] If the extractor hood 1 is installed in the kitchen cabinet 100, the exhaust air duct 4 must be installed in accordance with the Fig. preferably arranged in contact with one of the side walls 101a, 101b, 101c of the kitchen cabinet 100.

[0063] In other words, when the extractor hood 1 is integrated into a kitchen cabinet 100, the exhaust air duct 4 is arranged in a peripheral section of the cavity 102 along the depth direction YY ( Fig. or latitude direction XX ( Fig. For example, in the Fig. shown embodiment, the exhaust air duct 4 is arranged in contact with the aforementioned bottom wall 101a; in contrast, in the embodiment shown in the Fig. In the embodiment shown, the exhaust air duct 4 is in contact with one of the side walls 101b, 101c forming the flanks of the main body 101 of the kitchen cabinet 100.

[0064] According to one aspect, the exhaust air duct 4 has as its minimum extension direction the direction oriented orthogonally to the side wall 101a, 101b, 101c, to which it is assigned when the extractor hood 1 is installed in the kitchen cabinet 1.

[0065] According to a further aspect, the first and second bodies 2, 3—which, as described above, are arranged from opposite parts of the exhaust duct 4 along the height direction ZZ—protrude from the exhaust duct 4 along the depth direction YY or width direction XX. It should be noted that the extractor hood 1 essentially assumes a C-shape, which is suitable for occupying the cavity 102 only peripherally, leaving the central section free for storing food and / or cookware.

[0066] The extractor hood 1, which is the subject of the present description, also comprises an extraction group 5, which is arranged in the internal volume 30 of the second body 3 and is provided with an exhaust air pipe 50 leading out of this body 3.

[0067] When actuated, the extraction group 5 is configured to create a negative pressure (i.e. a condition in which the pressure value is below atmospheric pressure) in the internal volume 30 of the second body 3, which leads to the formation of a direct extraction flow of the cooking vapors along a flow path P. The latter extends from the extraction opening 20 via the exhaust duct 4 to the exhaust pipe 50 ( Fig. .

[0068] According to one aspect, the extraction group 5 comprises an impeller (not shown in the figures) having a direct axis of rotation along the vertical direction ZZ. This advantageously allows the extension of the second body 3 in the vertical direction ZZ to be reduced, benefiting the storage capacity of the kitchen cabinet 100.

[0069] The exhaust duct 50 of the extraction group 5 can discharge into the kitchen or into an external environment. Specifically, if the extractor hood 1 is of the filter type, the exhaust duct 50 is configured to redirect the exhaust flow to the room in which the extractor hood is located; otherwise, if the extractor hood 1 is of the extraction type, the exhaust duct 50 is configured to expel the exhaust flow to an external environment. It is therefore obvious that the extractor hood 1, which is the subject of this description, can be either a filter type or an extraction type.

[0070] The extractor hood 1 also includes a filter group 6 configured to filter grease and / or odors in the cooking vapors.

[0071] This filter group 6 is arranged along the flow path P between the extraction opening 20 and the extraction group 5, so that when the latter is activated, it is passed through by the extraction flow on which it acts to remove fats and / or odors in the cooking vapors.

[0072] In the extractor hood according to this invention, the filter group 6 is arranged at least partially in the exhaust air duct 4 along the height direction ZZ.

[0073] Preferably, the filter group 4 comprises both a grease and an odor filter.

[0074] It should be noted that such grease and odor filters can be integrated into a single filter element or into two or more separate filter elements, which can also be present in different sections of the flow path P.

[0075] If the filter group 6 comprises both a grease filter and an odor filter arranged in separate filter elements, it is appropriate to specify that the grease filter must necessarily be arranged upstream of the extraction group 5 to prevent the grease present in the cooking fumes from impairing its function; the odor filter can be placed both upstream and downstream of the extraction group 5. For example, according to a possible embodiment not shown in the attached figures, the odor filter is arranged in the exhaust duct 50 or downstream thereof.

[0076] It should be noted that, in the context of the present invention, the terms “grease filter” and “odor filter” are understood to mean filter media that are each configured to filter fats and molecules that are responsible for the odors of cooking vapors.

[0077] According to one aspect, the filter group 6 has a filter surface 60 that is at least partially flat and oriented transversely to the vertical direction ZZ. This arrangement, inclined to the vertical direction ZZ, advantageously allows for filter surfaces with larger surface areas to be obtained, which improves filtration efficiency.

[0078] In the Fig. In the embodiment shown, the filter surface 60 is arranged at least partially in the exhaust air duct 4 and inclined to the height direction ZZ, in particular by an angle of less than 90 degrees.

[0079] With reference to Fig. the second body 2 comprises a movable element 21 associated with the suction opening 20, which can be switched between a maintenance position and an operating position.

[0080] In the maintenance position, the movable element 21 allows access to the exhaust duct 4 to enable the removal of the filter group 4 along the vertical direction ZZ towards the underlying cooking surface 200; conversely, in the operating position, the movable element 21 prevents access to the exhaust duct 4.

[0081] In the Fig. In the embodiment shown, the first body 2 comprises hinge members 22 associated with the movable element 21 and configured to allow its rotation about a hinge axis RR. By rotating about this axis, the movable element 21 switches between the operating and maintenance positions.

[0082] According to one aspect, the movable element 21 is oriented transversely to the vertical direction ZZ in the operating position, partially obstructing the suction opening 20; in contrast, the movable element 21 is oriented substantially along the vertical direction ZZ in the maintenance position, thereby widening the suction opening 20 and allowing access to the filter group 6.

[0083] The first body 2 preferably comprises a deflector plate 23 which is configured to deflect the suction flow from the suction opening 21 directly to the filter group 6, in particular to the filter surface 60.

[0084] In the Fig. In the embodiment shown, the deflector plate 23 is arranged above the extraction opening 20 and extends transversely to the height direction ZZ in the direction of the exhaust air duct 4.

[0085] With regard to the Fig. In the flow path P shown, the deflector plate 23 is configured to divert the suction flow flowing in from the suction opening 20 into the exhaust air duct 4, in particular in such a way that it hits the filter group essentially orthogonally immediately after leaving the suction opening.

[0086] Also with regard to the Fig. In the embodiment shown, the deflector plate 23 with the movable element 21 in the operating position defines a through-opening 24, which is arranged downstream of the suction opening 20 and faces the filter group 6. As soon as the suction flow has passed this through-opening 24, it acts directly on the filter group 6 without undergoing any further flow deflection.

[0087] According to one aspect, the first body 2 has a stop surface 25 functionally associated with the filter group 6 for support. This stop surface 25 extends transversely to the height direction ZZ and is configured such that it meets the filter group 6 at the stop for support. With reference to Fig. the filter group 6 is partially inserted into the first body 2 along the height direction ZZ so that it rests against the stop surface 25.

[0088] According to a further aspect, the exhaust air duct 4 has a support surface 40 configured to receive the filter group 6 at the stop. The filter group 6 therefore preferably extends along the vertical direction ZZ between the stop surface 25 and the support surface 40, so that the direct extraction flow along the flow path P flows through it.

[0089] In the embodiment Fig. the extractor hood 1 comprises an additional first body 2a which defines an additional extraction opening 20a.

[0090] In alternative embodiments without the additional first body 2a, the additional suction opening 20a can be obtained on the first body 2 in addition to the suction opening 20.

[0091] In the embodiment of Fig. the extractor hood 1 also comprises an additional exhaust air duct 4a, which is configured to be arranged on one of the side walls 101a, 101b, 101c of the kitchen cabinet 100, preferably in contact therewith.

[0092] It should be noted that the side wall with the additional exhaust duct 4a differs from the one with the exhaust duct 4. Preferably, the exhaust duct 4 and the additional exhaust duct 4a are associated with opposite side walls, such as the walls 101b and 101c defining the flanks of the main body 101.

[0093] The additional exhaust air duct 4a extends predominantly along the height direction ZZ between the additional first body 2 (or the first body 2) and the second body 3 in order to fluid-dynamically connect the internal volume 30 to the additional suction opening 20a.

[0094] The above description for exhaust air duct 4 also applies to the additional exhaust air duct 4a.

[0095] The present description further relates to a kitchen cabinet 100 comprising a main body 101 as described above and an extractor hood 1 accommodated in the cavity 102 defined by the main body 101.

[0096] In detail, the extractor hood 1 is arranged in the cavity 102 with the exhaust air duct 4, which is arranged - preferably in contact - with one of the side walls 101a, 101b, 101c of the main body 100, the first body 2 in the lower region 102a and the second body 3 in the upper region 102b.

[0097] The exhaust air duct 4 is preferably set in extension along the height direction ZZ, so that the first body 2 and the second body 3 are arranged in the lower region 102a and in the upper region 102b of the cavity 102, respectively.

[0098] According to one aspect, the second body 3 is arranged in contact with the upper wall 101.

[0099] According to an additional aspect, the first body 2 is arranged below the supporting wall 100e along the height direction ZZ.

[0100] Of course, a technician in the industry may make numerous changes and variations to the configurations described above to meet contingent and specific requirements. These variations and modifications are, moreover, all within the scope of the invention, as defined in the following claims.
