Description

Cooker hood for extracting cooking fumes and kitchen cabinet incorporating this hood

The present invention relates to a hood for the extraction of cooking fumes which finds useful application in the kitchen equipment sector.

The present invention also relates to a kitchen unit incorporating said hood which finds useful application in the kitchen furniture sector.

State of the Art

Suspended hoods have been known for a long time; they are devices for extracting cooking fumes from an underlying cooktop.

These suspended hoods have a first body defining an extraction opening leading to the cooktop in order to be exposed to the upward flow of cooking fumes coming from the latter.

In use, a suction unit, arranged in a second special hollow section body placed above the first body and fluidodynamically connected to the suction opening by a suction duct, generates a suction flow through the suction opening which is reminiscent of rising cooking fumes.

Before being discharged, the extraction stream containing cooking fumes is properly filtered by a filtration unit located in the first section, just above the extraction opening. This filtration unit is configured to filter grease and/or odors present in the extracted stream so that it can then be recirculated back into the kitchen (filtering hood) or expelled into the outside environment (extractor hood), depending on the hood's configuration.

In the current state of the art, it is known to integrate these suspended hoods into special kitchen cabinets designed for food storage as well as to cover the hoods themselves. These cabinets therefore have both aesthetic and functional value.

To meet the storage needs of larger families and to provide kitchens with good capacity despite their small size, cooks are increasingly interested in increasing the number and volume of compartments for storing food and pots and pans.

To this end, C-shaped cooker hoods have been developed in which the extraction duct, fluid-dynamically connecting the extraction opening to the extraction unit, is located near the back wall of the kitchen cabinet. This duct features an extension that allows the first and second sections of the cooker to be positioned vertically on opposite sides of the cabinet, specifically near the lower and upper sections of the cabinet, respectively.

It is therefore obvious that C-shaped hoods allow for a large storage compartment in the central region of the unit – that is, between the first and second sections – in which dishes and/or pans can be stored.

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

The drawback in standard cooker hoods is the maximum thickness of the first section in the vertical direction, which cannot be reduced further due to the placement of the extraction unit directly above the extraction opening. This filter assembly placement therefore imposes a limit on the minimum thickness of the first section in the vertical direction, below which it is not possible to go.

In the state of the art, we know of some hoods which have at least part of the filtration unit located in the second body upstream of the suction unit.

It should be noted, however, that the second body, due to its significantly elevated position relative to the walking surface, is difficult for the user to access. Consequently, the location of the filter unit in the second body considerably complicates periodic maintenance/replacement of the filter unit.

Object of the invention

In this context, the task of the technician at the basis of the present invention is to propose a hood for the extraction of cooking fumes and a kitchen unit integrating this hood which overcome the disadvantages of the known technique mentioned above.

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

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

In accordance with the present invention, the indicated technical task and the specified objectives are achieved by a hood for the extraction of cooking fumes and by a kitchen unit incorporating this hood in accordance with the present invention.

The present invention relates to a cooker hood for extracting cooking fumes configured to be integrated into a kitchen unit in a vertical direction, said hood comprising: - a first body defining an opening for extracting cooking fumes, the first body being configured to be positioned above a cooktop in the vertical direction so as to make the extraction opening visible at the cooktop; - a second body with a hollow cross-section defining an internal volume and spaced from the first body in the vertical direction, the first and second bodies being located in opposite parts of the kitchen unit in the vertical direction; - an extraction duct located at the side of the kitchen unit, said extraction duct extending mainly in the vertical direction, connecting the first and second bodies and fluidodynamically connecting the internal volume to the extraction opening; - an extraction unit disposed within the internal volume of the second body and having an exhaust exiting from the second body, said extraction unit being configured to generate a direct extraction flow of cooking fumes along a fluidodynamic path extending from the extraction opening to the exhaust duct via the extraction duct; - a filter unit, configured to filter grease and/or odors present in the cooking fumes, disposed along the fluidodynamic path between the extraction opening and the extraction unit, the filter unit being at least partially disposed in the extraction duct in the vertical direction, characterized in that the first body has a movable element switchable between: - a maintenance position in which it allows access to the extraction duct in order to allow the removal of the filter unit in the vertical direction towards the cooktop; and - an operating position preventing the removal of the filter unit from the extraction duct.

In detail, the present invention proposes to arrange the filter group at least partially in the suction duct in the vertical direction.

By 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.

Thus, the present invention makes it possible to maximize the storage capacity of the kitchen unit in which the hood is integrated by reducing the thickness of the first body in the vertical direction.

It should also be noted that the filter group, being at least partially located in the suction duct, is easily accessible and removable/mounted through the suction opening.

According to a particular feature of the invention, the filter group has a filter surface having, at least partially, a planar conformation; the filter surface is oriented transversely with respect to the height direction and is at least partly disposed in the suction duct.

According to a particular feature of the invention, The first body includes hinge elements associated with the moving element and configured to allow the rotation of the moving element around a hinge axis so as to switch between the operating position and the maintenance position.

According to a particular feature of the invention, The first body includes a deflector configured to divert the suction flow from the suction opening directly onto the filter group.

According to a particular feature of the invention, The deflector, with the moving element in the operating position, defines a passage opening located downstream of the suction opening and leading to the filter group.

According to a particular feature of the invention, the first body has a stop surface oriented transversely to the height direction and configured to support the filter group; the filter group being partially inserted into the first body so as to stand against the stop surface.

According to a particular feature of the invention, the suction duct has a support surface configured to receive the filter group against it; the filter group extends in the vertical direction between the abutment surface and the support surface in order to be traversed by the direct suction flow along the fluidodynamic path.

According to a particular feature of the invention, The first body and the second body protrude from the suction duct in a depth direction oriented transversely to the height direction.

The present invention also relates to a kitchen unit extending in a vertical direction, a horizontal direction, and a horizontal direction defining a three-dimensional Cartesian reference system, characterized by the fact that said kitchen unit comprises: - a main body defining a cavity extending in the vertical direction between a lower region and an upper region, the main body having a plurality of lateral walls delimiting the cavity in the horizontal and horizontal directions; - a hood, as described above, housed in the cavity of the main body so as to have: - the extraction duct at the level of a lateral wall of the kitchen unit, - the first body in the lower region so that it opens onto a cooktop; - the second body in the upper region.

According to a particular feature of the invention, The main body has: - an upper wall delimiting the upper cavity in the vertical direction, the second body being arranged in contact with the upper wall; - a support wall arranged in the lower region and extending in the horizontal direction by joining two opposite lateral walls; - the first body being arranged below the support wall in the vertical direction.

DETAILED DESCRIPTION

With reference to the attached figures, this description relates to a hood 1 for the extraction of cooking fumes, which can be integrated into a kitchen unit 100.

It is worth noting that the hood 1 referred to in this description is of the suspended or under-cabinet type, that is to say configured to be mounted above a cooktop 200 in the direction of natural upward movement of cooking fumes.

With particular reference to the FIG. 1 The hood 1 and the kitchen unit 100 extend in a vertical direction ZZ (identifiable with the natural upward direction of cooking fumes), a horizontal direction XX, and a horizontal direction YY, which define a three-dimensional, tri-orthogonal Cartesian reference system. That is to say, the vertical directions ZZ, horizontal directions XX, and horizontal directions YY are mutually oriented perpendicularly.

The kitchen unit 100 includes a main body 101 defining an internal cavity 102 which can house the hood 1 and, in the remaining space, store any provisions and/or pans.

This cavity 102 extends in the height direction Z-Z between a lower region 102a and an opposite upper region 102b, separated by a central region 102c.

With reference to the FIG. 1 When kitchen cabinet 100 is installed above a cooktop 200 in the ZZ height direction, the lower region 102a faces the top of the cooktop 200 so that it is exposed to the flow of cooking fumes that rise from it during use. Kitchen cabinet 100 is therefore of the suspended type.

The cavity 102 also extends in the width X-X and depth Y-Y directions, thus assuming a three-dimensional conformation.

In detail, the main body 101 has a plurality of side walls 101a, 101b, 101c delimiting the cavity 102 in the width direction X-X and the depth direction Y-Y.

In the embodiment illustrated on the FIG. 1 , the lateral walls 101a, 101b, 101c delimit the cavity 102 on at least three sides.

Preferably, there are at least three side walls, two of which 101b, 101c (sides of the main body 101) are opposite in the width direction X-X and a third wall 101a (bottom wall of the main body) extending in the width direction X-X, joining opposite parts to the other two 101b, 101c.

Each side wall 101a, 101b, 101c extends in the vertical direction between the lower region 102a and the upper region 102b.

In the embodiment illustrated on the FIG. 1 The kitchen unit 1 also includes an upper wall 101d which defines the upper boundary of the cavity 102 in the height direction ZZ. This upper wall 101 therefore defines the upper region 102b of the cavity 102 in the height direction ZZ.

Still referring to the method of implementation of the FIG. 1 , the upper wall 101d is connected to the lateral walls 101a, 101b, 101c thus defining the ceiling of the cavity 102.

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

According to one aspect, the supporting wall 100e is opposite the upper wall 101d in the height direction Z-Z.

Preferably, the support wall 100e delimits the lower region 102a above and the central region 102c below of the cavity 102.

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

The hood 1, which is the subject of this description, is configured to be integrated into the kitchen unit 100, more precisely into said cavity 102, in the height direction Z-Z.

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 Z-Z.

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.

The first and second bodies 2, 3 are thus spaced in the height direction Z-Z of the central region 102c of the cavity 102. The central region 102c is configured as well as the storage region of the cavity 102, that is to say, that part of the cavity 102 which can be occupied by food and/or pans.

In detail, the first body 2 defines an extraction opening 20 for cooking fumes, that is to say an opening through which the hood 1 is configured to draw in the cooking fumes to be treated from the cooktop below.

With reference to the FIG. 1 The hood 1 is configured so that the first body 2 is placed above the cooktop 200 in the height direction ZZ, so that the extraction opening 20 faces it. The hood 1 is therefore a suspended or under-cabinet type hood.

The second body 3 has a hollow section conformation defining an internal volume 30 which can receive a suction group 5. More details on the suction group 5 will be provided in a later part of the description.

Preferably, the second body 3 extends mainly in the width direction X-X and in the depth direction Y-Y.

The second body 3 is spaced from the first body 2 in the height direction Z-Z. 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 placed in the upper region 102b of the cavity 102, preferably in contact with or near the upper wall 101d.

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 upper cavity 102, thus effectively replacing the upper wall 101d of the suspended unit 101 which, consequently, can be devoid of this component.

The hood 1 also includes a suction duct 4 extending mainly in the height direction Z-Z, connecting the first and second bodies 2, 3 and fluidodynamically connecting the internal volume 30 to the suction opening 20.

In use, when the suction group 5 (described below) is activated, the suction duct 4 carries 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.

It should be noted that the extension of the suction duct 4 in the Z-Z vertical direction defines the relative position of the first and second bodies 2 and 3 in the same direction. In other words, the extension of the suction duct 4 in the Z-Z vertical direction imposes the separation of the first body 2 from the second body 3 in the Z-Z vertical direction.

According to one embodiment, the extraction duct 4 of the hood 1 is configured to adjust its extension in the height direction Z-Z in order to allow the first and second bodies 2, 3 to be placed at different distances in the height direction Z-Z depending on the extension of the kitchen unit 100 in this height direction Z-Z.

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

In the embodiment shown in the FIG. 2 and detailed on the FIG. 2 , the suction duct 4 comprises a first section 41 and a second section 42 connected telescopically in the height direction ZZ.

It is important to clarify that, within the context of the present invention, the adjective "telescopically" refers to the fact that the first and second sections 41, 42 of the suction duct 4 are slidably inserted into one another in the vertical direction Z-Z. By sliding mutually, the first and second sections 41, 42 vary the extension of the suction duct 4 in the vertical direction Z-Z and thus the relative positions of the first and second bodies 2, 3 in the same direction.

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 Z-Z.

In particular, according to one aspect, the first section 41 extends in the height direction Z-Z between a first end 41a connected to the first body 2 and a first connecting end part 41b; while, the second section 42 extends in the height direction Z-Z between a second end 42a connected to the second body and a second connecting end part 42b.

The first and second connecting end sections 41b, 42b are then slidably inserted into one another in the Z-Z height direction 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. Therefore, by varying the length of the overlapping section of the first and second connecting ends 41b, 42b, it is possible to adjust the spacing between the first and second bodies 2, 3 in the Z-Z height direction to suit the geometric characteristics of the kitchen unit 100.

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.

In other words, when the hood 1 is integrated into a kitchen unit 100, the extraction duct 4 is located in a peripheral part of the cavity 102 in the depth direction YY ( FIG. 2 ) or the width direction XX ( FIG. 5 ). 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.

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

According to another aspect, the first and second bodies 2, 3 – which, according to the above, are arranged by opposite parts of the extraction duct 4 in the vertical direction Z-Z – project from the extraction duct 4 in the vertical direction Y-Y or horizontal direction X-X. It should be noted that, in doing so, the hood 1 essentially assumes a C-shaped configuration that can only peripherally occupy the cavity 102, leaving the central part free for the storage of any food and/or pans.

The hood 1 which is the subject of this description also includes a suction unit 5 located in the internal volume 30 of the second body 3 and provided with an exhaust duct 50 exiting from the latter 3.

When activated, the suction unit 5 is configured to generate a vacuum in the internal volume 30 of the second body 3 (i.e., a condition in which the pressure value is lower than atmospheric pressure) which leads to the formation of a direct suction flow of cooking fumes along a fluidodynamic path P. The latter extends from the suction opening 20 to the exhaust duct 50, passing through the suction duct 4 ( FIG. 2 ).

In one aspect, the suction unit 5 includes a wheel (not shown in the figures) with a direct axis of rotation in the Z-Z height direction. Advantageously, this reduces the extension of the second unit 3 in the Z-Z height direction, thus increasing the storage capacity of the kitchen unit 100.

The exhaust duct 50 of the extraction unit 5 can terminate both in the kitchen and in an external environment. Specifically, if the hood 1 is a recirculating type, the exhaust duct 50 is configured to recirculate the extraction airflow back into the room where the hood is located; otherwise, if the hood 1 is an ducted type, the exhaust duct 50 is configured to expel the extraction airflow into an external environment. It is therefore clear that the hood 1 described herein can be both a recirculating and an ducted type.

Hood 1 also includes a group of 6 filters configured to filter grease and/or odors present in cooking fumes.

This group of filters 6 is arranged along the fluidodynamic path P between the suction opening 20 and the suction group 5 so that when the latter is activated, it is traversed by the suction flow on which it acts to eliminate grease and/or odors present in the cooking fumes.

In the hood according to the present invention, the filter group 6 is at least partially disposed in the suction duct 4 in the height direction Z-Z.

Preferably, filter group 4 includes both a grease filter and an odor filter.

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 fluidodynamic path P.

If the filter group 6 includes 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 accompanying figures, the odor filter is placed in the exhaust duct 50 or downstream of the latter.

It should be specified that in the context of the present invention, the terms "grease filter" and "odor filter" refer to filtering means respectively configured to filter grease and molecules responsible for odors from cooking fumes.

According to one aspect, the filter group 6 has a filter surface 60 having, at least in part, a planar conformation oriented transversely with respect to the height direction Z-Z. Advantageously, such an arrangement inclined with respect to the height direction Z-Z makes it possible to obtain filter surfaces with larger surface areas, thus improving filtration efficiency.

In the embodiment shown in the FIG. 3 , the filter surface 60 is at least partially disposed in the suction duct 4 and inclined with respect to the height direction ZZ, in particular, at an angle of less than 90 degrees.

With reference to the FIG. 2 , the second body 2 includes a movable element 21, associated with the suction opening 20, switchable between a maintenance position and an operating position.

In the maintenance position, the movable element 21 allows access to the suction duct 4 to allow the removal of the filter group 4 in the height direction Z-Z towards the cooking table 200 below; otherwise, in the operating position, the movable element 21 inhibits access to the suction duct 4.

In the embodiment illustrated on the FIG. 2 The first body 2 includes hinge members 22 associated with the moving element 21 and configured to allow the latter to rotate around a hinge axis RR. By rotating around this axis, the moving element 21 switches between the operating position and the maintenance position.

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

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

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 Z-Z, towards the suction duct 4.

With reference to the fluidodynamic path P shown on the FIG. 2 , the deflector 23 is configured to divert the incoming suction flow from the suction opening 20 towards the suction duct 4, in particular so that it affects the filter group substantially orthogonally immediately after leaving it.

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, located downstream of the suction opening 20, leading to the filter group 6. The suction flow, once this passage opening 24 has been passed, directly affects the filter group 6 without undergoing any further deflection.

According to one aspect, the first body 2 has a buttress surface 25 functionally associated with the filter group 6 for support. This buttress surface 25 extends transversely to the height direction ZZ and is configured to receive the filter group 6 as a buttress for support. With reference to the FIG. 2 , the filter group 6 is partly inserted into the first body 2 in the height direction ZZ in order to fit against the abutment surface 25.

According to another aspect, the suction duct 4 has a bearing surface 40 configured to receive the filter group 6 as a butt. The filter group 6 therefore extends preferably in the height direction Z-Z between the butt surface 25 and the bearing surface 40 in order to be crossed by the direct suction flow along the fluidodynamic path P.

In the implementation of the FIG. 5 , the hood 1 includes a first additional body 2a defining an additional suction opening 20a.

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.

In the embodiment of Figures 5a and 5b, the hood 1 also includes 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.

It should be specified that the side wall to which the additional suction duct 4a is associated is different – and therefore distinct – from that to 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.

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

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

Also included in this 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.

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.

The suction duct 4 is preferably set in extension in the height direction Z-Z in order to place the first body 2 and the second body 3 respectively in the lower region 102a and the upper region 102b of the cavity 102.

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

According to another aspect, the first body 2 is disposed below the support wall 100e in the height direction Z-Z.

Clearly, an expert in the field, in order to meet contingent and specific needs, may make numerous modifications and variations to the configurations described above. These variations and modifications are, moreover, all contained within the scope of the invention.
