Description

Title of the invention: Hood for extracting cooking fumes and kitchen unit incorporating this hood Technical field

[0001] The present invention relates to a hood for extracting cooking fumes which finds useful use in the kitchen equipment sector.

[0002] The present invention also relates to a kitchen unit incorporating said hood which finds useful use in the sector of furnishing kitchen premises. State of the Art

[0003] Suspended hoods have been known for a long time, i.e. equipment for extracting cooking fumes from an underlying cooking hob.

[0004] These suspended hoods have a first body defining a suction opening opening onto the cooking table in order to be exposed to the upward flow of cooking fumes coming from the latter.

[0005] In use, a suction group, arranged in a second body of special hollow section placed above the first body and fluid-dynamically connected to the suction opening by a suction duct, generates a suction flow through the suction opening which recalls the ascending cooking fumes.

[0006] Before being discharged, the suction flow containing the cooking fumes is suitably filtered by a filtration group arranged in the first body just above the suction opening. This filtration group is configured to filter the grease and / or odors present in the suction flow so that it can then be reinjected into the kitchen (filter hood) or expelled into the outside environment (extractor hood) depending on the configuration of the hood.

[0007] In the state of the art, it is known to integrate these suspended hoods into special kitchen furniture intended for storing food as well as for covering the hoods themselves. These pieces of furniture therefore have both aesthetic and functional value.

[0008] Cooks, in order to meet the storage needs of larger families and to provide kitchens of good capacity although small in size, are increasingly interested in increasing the number and cubature of compartments for storing food and pans.

[0009] For this purpose, hoods having a C-shaped conformation have been developed in which the suction duct fluidodynamically connecting the suction opening to the suction unit is available close to the back wall of the kitchen unit. This duct is characterized by an extension allowing the first and second body in opposite parts of the kitchen unit in the height direction, in particular respectively near the lower and upper parts of the kitchen unit.

[0010] It is therefore evident that the C-shaped hoods make it possible to obtain a large storage compartment in the central region of the furniture - that is to say between the first and the second body -, in which dishes and / or pans can be stored.

[0011] It should however be noted that, with equal extension of the furniture in the height direction, the central storage region is all the greater as the thickness of the first and second bodies is smaller in the height direction.

[0012] The disadvantage in known hoods is the thickness of the first body in the height direction which cannot be reduced further due to the arrangement of the suction group just above the suction opening. This arrangement of the filter group therefore imposes a limit on the minimum thickness of the first body in the height direction, below which it is not possible to go.

[0013] In the state of the art, some hoods are known which have at least part of the filtration group arranged in the second body upstream of the suction group.

[0014] It should be noted, however, that the second body, due to its location substantially raised relative to the walking surface, is difficult for the user to access. Consequently, the location of the filtration unit in the second body considerably complicates periodic maintenance / replacement operations of the filtration unit.

[0015] Object of the invention

[0016] In this context, the task of the technician behind the present invention is to propose a hood for extracting cooking fumes and a kitchen unit incorporating this hood which overcome the drawbacks of the known technique mentioned above.

[0017] In particular, the aim of the present invention is to provide a hood for extracting cooking fumes which, in addition to allowing easy and rapid replacement / maintenance of the filtration unit, is able to maximize the storage volume of the kitchen unit in which it is integrated.

[0018] The aim of the present invention is also to provide a kitchen unit incorporating a hood for extracting cooking fumes which is both spacious and practical to use. Summary of the invention

[0019] According to the present invention, the indicated technical task and the specified objectives are achieved by a hood for extracting cooking fumes and by a kitchen unit incorporating this hood in accordance with the present invention.

[0020] The present invention relates to a hood for extracting cooking fumes configured to be integrated into a kitchen unit in a height direction, said hood comprising: - a first body defining a cooking fume extraction opening, the first body being configured to be arranged above a cooking hob in the height direction so as to expose the extraction opening to the cooking hob; - a second body of hollow section defining an internal volume and spaced from the first body in the height direction, the first body and the second body being available in opposite parts of the kitchen unit in the height direction;- a suction duct available in correspondence with a side wall of the kitchen unit, said suction duct extending mainly in the height direction by connecting the first body and the second body and by fluidodynamically connecting the internal volume to the suction opening; - a suction group arranged in the internal volume of the second body and having an exhaust exiting from the second body, said suction group being configured to generate a direct suction flow of cooking fumes along a fluidodynamic path extending from the suction opening to the exhaust duct via the suction duct;- a filter group, configured to filter grease and / or odors present in the cooking fumes, arranged along the fluid-dynamic path between the suction opening and the suction group, the filter group being at least partially arranged in the suction duct in the height direction, characterized in that the first body has a movable element switchable between: - a maintenance position in which it allows access to the suction duct in order to allow removal of the filter group in the height direction towards the cooking hob; and - an operating position preventing removal of the filter group from the suction duct. ;

[0021] In detail, the present invention proposes to arrange the filter group at least partially in the suction duct in the height direction.

[0022] In doing so, it is possible to detach the extension of the first body in the height direction from the physical footprint of the filter group.

[0023] Thus, the present invention makes it possible to maximize the storage capacity of the kitchen cabinet in which the hood is integrated by reducing the thickness of the first body in the height direction.

[0024] It should also be noted that the filter group, being at least partially arranged in the suction duct, is easily accessible and removable / mountable through the suction opening.

[0025] According to a particular characteristic of the invention, the group of filters has a filtering surface having, at least partially, a planar conformation; the filtering surface is oriented transversely with respect to the height direction and is at least partly arranged in the suction duct.

[0026] According to a particular characteristic of the invention, the first body comprises hinge members associated with the mobile element and configured to allow rotation of the mobile element around a hinge axis so as to switch between the operating position and the maintenance position.

[0027] According to a particular characteristic of the invention, the first body comprises a deflector configured to divert the suction flow from the suction opening directly onto the filter group.

[0028] According to a particular characteristic of the invention, the deflector defines with the movable element in the operating position a passage opening arranged downstream of the suction opening and opening onto the group of filters.

[0029] According to a particular characteristic of the invention, the first body has a stop surface oriented transversely to the height direction and configured to support the group of filters; the group of filters being partially inserted into the first body so as to be placed in abutment against the stop surface.

[0030] According to a particular characteristic of the invention, the suction duct has a bearing surface configured to receive the group of filters in abutment; the group of filters extends in the height direction between the abutment surface and the bearing surface in order to be crossed by the direct suction flow along the fluid-dynamic path.

[0031] According to a particular characteristic of the invention, the first body and the second body project from the suction duct in a depth direction oriented transversely to the height direction.

[0032] The present invention also relates to a kitchen unit extending in a height direction, a width direction, and a depth direction defining a three-dimensional Cartesian reference system, characterized in that said kitchen unit comprises: - a main body defining a cavity extending in the height direction between a lower region and an upper region, the main body having a plurality of side walls delimiting the cavity in the width direction and the depth direction; - a hood, as described above, housed in the cavity of the main body in order to arrange: - the suction duct at a side wall of the kitchen unit, - the first body in the lower region so that it opens onto a cooking hob; - the second body in the upper region.

[0033] According to a particular characteristic of the invention, the main body has: - an upper wall delimiting the upper cavity in the height direction, the second body being arranged in contact with the upper wall; - a support wall arranged in the lower region and extending in the width direction by joining two opposite side walls; - the first body being arranged below the support wall in the height direction.

[0043] With reference to the attached figures, the present description relates to a hood 1 for extracting cooking fumes which can be integrated into a kitchen unit 100.

[0044] It is worth specifying that the hood 1 which is the subject of the present description is of the suspended or under-cabinet type, that is to say configured to be mounted above a cooking hob 200 in the direction of natural rise of the cooking fumes.

[0045] With reference in particular to [Fig.l], the hood 1 and the kitchen unit 100 extend in a height direction ZZ (identifiable as the natural direction of rise of the cooking fumes), a width direction XX, and a depth direction YY which define a three-dimensional Cartesian reference system, in particular tri-orthogonal. That is to say that the directions of height ZZ, width XX and depth YY are mutually oriented perpendicularly.

[0046] The kitchen unit 100 comprises a main body 101 defining an internal cavity 102 capable of housing the hood 1 and, in the remaining space, storing any provisions and / or pans.

[0047] This cavity 102 extends in the height direction ZZ between a lower region 102a and an opposite upper region 102b, spaced from a central region 102c.

[0048] Referring to [Fig.l], when the kitchen cabinet 100 is installed above a cooking table 200 in the height direction ZZ, the lower region 102a faces above the cooking table 200 in order to be invested by the flow of cooking fumes which, in use, rise from the latter. The kitchen cabinet 100 is therefore of the suspended type.

[0049] The cavity 102 also extends in the directions of width XX and depth YY, thus assuming a three-dimensional conformation.

[0050] In detail, the main body 101 has a plurality of side walls 101a, 101b, 101c delimiting the cavity 102 in the width direction XX and the depth direction YY.

[0051] In the embodiment illustrated in [Fig.l], the side walls 101a, 101b, 101c delimit the cavity 102 on at least three sides.

[0052] Preferably, the side walls are at least three, two of which 101b, 101c (sides of the main body 101) are opposite in the width direction XX and a third wall 101a (bottom wall of the main body) extends in the width direction XX, joining in opposite parts to the other two 101b, 101c.

[0053] Each side wall 101a, 101b, 101c extends in the height direction between the lower region 102a and the upper region 102b.

[0054] In the embodiment illustrated in [Fig.l], the kitchen unit 1 also comprises an upper wall 101d delimiting the cavity 102 above in the height direction ZZ. This upper wall 101 therefore delimits the upper region 102b of the cavity 102 in the height direction ZZ.

[0055] Still with reference to the embodiment of [Fig.l], the upper wall 101 is connected to the side walls 101a, 101b, 101c thus defining the roof of the cavity 102.

[0056] The main body 101 may also comprise a bearing wall 100e disposed in the lower region 102a and extending in the width direction XX by joining two opposite side walls - for example, the above side walls have been defined as the flanks 101b, 101c of the main body 101.

[0057] According to one aspect, the bearing wall 100e is opposite the upper wall 100d in the height direction ZZ.

[0058] Preferably, the support wall 100e delimits the lower region 102a at the top and the central region 102c at the bottom of the cavity 102.

[0059] Advantageously, the support wall 100e, in addition to providing structural rigidity to the main body 101 of the kitchen unit 100, defines a support plane for all the provisions and / or pans available in the cavity 102.

[0060] The hood 1 which is the subject of the present description is configured to be integrated into the kitchen unit 100, more precisely in said cavity 102, in the height direction ZZ.

[0061] With reference to figures 2a and 3, the hood 1 comprises a first and a second body 2, 3 available in opposite parts of the kitchen unit 100 in the height direction ZZ.

[0062] According to one aspect, the first body 2 is available in the lower region 102a of the cavity 102 while the second body 3 is available in the upper region 102b of the cavity 102.

[0063] 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 configured as well as the storage region of the cavity 102, i.e. this part of the cavity 102 which can be occupied by food and / or pans

[0064] In detail, the first body 2 defines a suction opening 20 for the cooking fumes, that is to say an opening through which the hood 1 is configured to suck up the cooking fumes to be treated coming from the underlying cooking hob.

[0065] With reference to [Fig. 1], the hood 1 is configured to place the first body 2 above the cooking table 200 in the height direction ZZ, so that the suction opening 20 faces it. The hood 1 is therefore a suspended or under-cabinet type hood.

[0066] The second body 3 has a hollow section conformation defining an internal volume 30 capable of receiving a suction group 5. More details on the suction group 5 will be provided in a following part of the description.

[0067] Preferably, the second body 3 extends mainly in the direction of width XX and in that of depth YY.

[0068] The second body 3 is spaced from the first body 2 in the height direction ZZ. In particular, when the hood 1 is integrated into the kitchen unit 100 with the first body 2 placed 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 or close to the upper wall 102.

[0069] According to an alternative embodiment to that illustrated in the attached figures, when the hood 1 is integrated into the kitchen unit 101, the second body 3 closes the cavity 102 at the top, thus replacing the upper wall 102 of the suspended unit 101 which, consequently, can be devoid of this component.

[0070] The hood 1 also comprises a suction duct 4 extending mainly in the height direction ZZ by connecting the first and second bodies 2, 3 and by fluidodynamically connecting the internal volume 30 to the suction opening 20.

[0071] In use, when the suction group 5 (described below) is actuated, the suction duct 4 conveys a suction flow containing the cooking fumes from the suction opening 20 of the first body 2 to the internal volume 30 of the second body 3.

[0072] It should be noted that the extension of the suction duct 4 in the height direction ZZ defines the relative position of the first and second bodies 2, 3 in the same direction. In other words, the extension of the suction duct 4 in the height direction ZZ imposes the spacing of the first body 2 from the second body 3 in the height direction ZZ.

[0073] According to one embodiment, the suction duct 4 of the hood 1 is configured to adjust its extension in the height direction ZZ in order to allow the first and second bodies 2, 3 to be arranged at different distances in the height direction ZZ depending on the extension of the kitchen unit 100 in this height direction ZZ.

[0074] Therefore, preferably, the suction duct 4 is configured to extend and count in the height direction ZZ in order to modify the relative position of the first body 2 with respect to the second body 3 in the same direction ZZ to adapt to the geometric characteristics of the kitchen furniture in which it is integrated.

[0075] In the embodiment shown in [Fig.2a] and detailed in [Fig.2b], the suction duct 4 comprises a first section 41 and a second section 42 telescopically connected in the height direction ZZ.

[0076] It is worth noting that in the context of the present invention, the adjective "telescopically" is intended to indicate that the first and second sections 41, 42 of the suction duct 4 are inserted in a sliding manner into each other in the height direction ZZ. By sliding together, the first and second sections 41, 42 vary the extension of the suction duct 4 in the height direction ZZ and therefore the reciprocal position of the first and second bodies 2, 3 in the same direction.

[0077] Still with reference to the embodiment shown in Figures 2a and 2b, the first and second sections 41, 42 extend - preferably predominantly - in the height direction ZZ.

[0078] In particular, according to one aspect, the first section 41 extends in the height direction ZZ between a first end 41a connected to the first body 2 and a first connecting end portion 41b; while the second section 42 extends in the height direction ZZ between a second end 42a connected to the second body and a second connecting end portion 42b.

[0079] The first and second connecting end portions 41b, 42b are then slidably inserted into each other in the height direction ZZ so that, by varying the length of their overlapping section, it is possible to modify the spacing between the first end 41a of the first section 41 and the second end 42a of the second section 42. Consequently, by varying the length of the overlapping section of the first and second connecting ends 41b, 42b, it is possible to act on the spacing between the first and second bodies 2, 3 in the height direction ZZ to adjust it according to the geometric characteristics of the kitchen cabinet 100.

[0080] According to figures 2a and 5a, when the hood 1 is mounted in the kitchen unit 100, the suction duct 4 is arranged in correspondence, preferably in contact, with one of the side walls 101a, 101b, 101c of the kitchen unit 100.

[0081] In other words, when the hood 1 is integrated into a kitchen unit 100, the suction duct 4 is arranged in a peripheral portion of the cavity 102 in the depth direction YY ([Fig.2a]) or the width direction XX ([Fig.5a]). For example, in the embodiment illustrated in Figures 1 and 2a, the suction duct 4 is arranged in contact with said bottom wall 101a; otherwise, in the embodiment illustrated in Figures 4 and 5a, the suction duct 4 is in contact with one of the side walls 101b, 101c which form the sides of the main body 101 of the kitchen unit 100.

[0082] According to one aspect, the suction duct 4 has as its minimum extension direction that oriented orthogonally to the side wall 101a, 101b, 101c with which it is associated when the hood 1 is installed in the kitchen unit 1.

[0083] According to another aspect, the first and second bodies 2, 3 - which, in accordance with the foregoing, are arranged by opposite portions of the suction duct 4 in the height direction ZZ - project from the suction duct 4 in the depth direction YY or width direction XX. It should be noted that, in doing so, the hood 1 essentially assumes a C-shaped conformation that can occupy only peripherally the cavity 102, leaving the central portion free for the storage of possible food and / or pans.

[0084] The hood 1 which is the subject of the present description also comprises a suction group 5 arranged in the internal volume 30 of the second body 3 and provided with an exhaust duct 50 exiting from the latter 3.

[0085] When actuated, the suction group 5 is configured to generate in the internal volume 30 of the second body 3 a depression (i.e. a condition in which the pressure value is lower than that of atmospheric pressure) which leads to the formation of a direct cooking fume suction flow along a fluid-dynamic path P. The latter extends from the suction opening 20 to the exhaust duct 50, passing through the suction duct 4 ([Fig.2a]).

[0086] According to one aspect, the suction group 5 comprises a wheel (not shown in the figures) having a direct axis of rotation in the height direction ZZ. Advantageously, this makes it possible to reduce the extension of the second body 3 in the height direction ZZ in favor of the storage capacity of the kitchen unit 100.

[0087] The exhaust duct 50 of the suction unit 5 can open both into the kitchen and into an environment outside the latter. In particular, if the hood 1 is of the filtering type, the exhaust duct 50 is configured to reintroduce the suction flow into the room in which the hood is placed; otherwise, if the hood 1 is of the suction type, the exhaust duct 50 is configured to expel the suction flow into an outside environment. It is therefore obvious that the hood 1 which is the subject of the present description can be both of the filtering and suction type.

[0088] The hood 1 also comprises a group of filters 6 configured to filter the grease and / or odors present in the cooking fumes.

[0089] This group of filters 6 is arranged along the fluid-dynamic path P between the suction opening 20 and the suction group 5 so that when the latter is actuated, it is crossed by the suction flow on which it acts to eliminate the grease and / or odors present in the cooking fumes.

[0090] In the hood according to the present invention, the filter group 6 is at least partially arranged in the suction duct 4 in the height direction ZZ.

[0091] Preferably, the group of filters 4 comprises both a grease filter and an odor filter.

[0092] It should be noted that these grease and odor filters can be integrated into a single filter element or into two or more separate filter elements, also available in different sections of the fluid-dynamic path P.

[0093] If the filter group 6 comprises both a grease filter and an odor filter organized into separate filter elements, it should be specified that the grease filter must necessarily be placed upstream of the suction group 5 to prevent the grease present in the cooking fumes from hindering its operation, the odor filter can be placed both upstream and downstream of the suction 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 of the latter.

[0094] It should be noted that in the context of the present invention, the terms “grease filter” and “odor filter” designate filtering means respectively configured to filter grease and molecules responsible for cooking fume odors.

[0095] According to one aspect, the group of filters 6 has a filtering surface 60 having, at least in part, a flat conformation and oriented transversely with respect to the height direction ZZ. Advantageously, such an arrangement inclined with respect to the height direction ZZ makes it possible to obtain filtering surfaces with larger surface extensions for the benefit of filtration efficiency.

[0096] In the embodiment shown in [Fig. 3], the filtering surface 60 is at least partially arranged in the suction duct 4 and inclined relative to the height direction ZZ, in particular, by an angle of less than 90 degrees.

[0097] With reference to [Fig.2a], the second body 2 comprises a movable element 21, associated with the suction opening 20, switchable between a maintenance position and an operating position.

[0098] In the maintenance position, the movable element 21 allows access to the suction duct 4 to allow removal of the filter group 4 in the height direction ZZ towards the underlying hob 200; otherwise, in the operating position, the movable element 21 inhibits access to the suction duct 4.

[0099] In the embodiment illustrated in [Fig.2a], the first body 2 comprises hinge members 22 associated with the movable element 21 and configured to allow the latter to rotate around a hinge axis RR. By rotating around this latter axis, the movable element 21 switches between the operating position and the maintenance position.

[0100] According to one aspect, in the operating position, the movable element 21 is oriented transversely in the height direction ZZ, partially obstructing the suction opening 20; otherwise, in the maintenance position, the movable element 21 is essentially oriented in the height direction ZZ, thus widening the suction opening 20 and allowing access to the filter group 6.

[0101] The first body 2 preferably comprises a deflector 23 configured to divert the suction flow from the suction opening 21 directly onto the filter group 6, in particular onto the filtering surface 60.

[0102] In the embodiment shown in Figures 2a and 3, the deflector 23 is arranged above the suction opening 20 and extends, transversely to the height direction ZZ, towards the suction duct 4.

[0103] With reference to the fluid-dynamic path P shown in [Fig.2a], the deflector 23 is configured to deflect the suction flow entering from the suction opening 20 towards the suction duct 4, in particular so that the latter affects the filter group in a substantially orthogonal manner immediately after leaving it.

[0104] Still with reference to the embodiment shown in Figures 2a and 3, the deflector 23 defines with the movable element 21 in the operating position a passage opening 24, arranged downstream of the suction opening 20, opening onto the filter group 6. The suction flow, once this passage opening 24 has passed, directly affects the filter group 6 without undergoing any additional deflection.

[0105] According to one aspect, the first body 2 has an abutment surface 25 operatively associated with the filter group 6 to support it. This abutment surface 25 extends transversely to the height direction ZZ and is configured to receive in abutment the filter group 6 to support it. With reference to [Fig.2a], the filter group 6 is partly inserted into the first body 2 in the height direction ZZ in order to abut against the abutment surface 25.

[0106] According to another aspect, the suction duct 4 has a bearing surface 40 configured to receive the filter group 6 in abutment. The filter group 6 therefore preferably extends in the height direction ZZ between the abutment surface 25 and the bearing surface 40 in order to be crossed by the direct suction flow along the fluid-dynamic path P.

[0107] In the embodiment of [Fig.5a], the hood 1 comprises a first additional body 2a defining an additional suction opening 20a.

[0108] 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.

[0109] In the embodiment of Figures 5a and 5b, the hood 1 also comprises another suction duct 4a configured to be arranged in correspondence, preferably in contact, with one of the side walls 101a, 101b, 101c of the kitchen unit 100.

[0110] It should be specified that the side wall with which the additional suction duct 4a is associated is different - and therefore distinct - from that with which the suction duct 4 is associated. Preferably, the suction duct 4 and the other suction duct 4a are associated with opposite side walls such as for example the walls 101b and 101c defining the sides of the main body 101.

[0111] The additional suction duct 4a extends mainly in the height direction ZZ between the first additional body 2 (or the first body 2) and the second body 3 in order to connect the internal volume 30 fluid-dynamically to the additional suction opening 20a.

[0112] The above for the suction duct 4 also applies to the additional suction duct 4a.

[0113] Also the subject of the present description is a kitchen unit 100 having a main body 101 in accordance with the above and a hood 1 housed in the cavity 102 defined by the main body 101.

[0114] In detail, the hood 1 is arranged in the cavity 102 with the suction duct 4 arranged in correspondence - preferably in contact - with one of the side walls 101a, 101b, 101c of the main body 100, the first body 2 placed in the lower region 102a and the second body 3 placed in the upper region 102b.

[0115] The suction duct 4 is preferably adjusted in extension in the height direction ZZ in order to arrange the first body 2 and the second body 3 respectively in the lower region 102a and the upper region 102b of the cavity 102.

[0116] According to one aspect, the second body 3 is arranged in contact with the upper wall 1Old.

[0117] According to another aspect, the first body 2 is arranged below the support wall 100e in the height direction ZZ.

[0118] Obviously, an expert in the art, in order to meet contingent and specific needs, will be able to make numerous modifications and variations to the configurations described above. These variations and modifications are moreover all contained within the scope of the invention.
