There are known hoods, which are also referred to as boxing. In these hoods, the fan box, in which the fan of the hood is inserted, sits on top of a viewing hood and is covered by a telescopic channel. So that the suspension is easily accessible, this is above the fan box. In order to ensure a plan concerns on the wall, while an additional locking screw in the wall is required, which must be screwed from the inside in the lower part of the fan box.

Such a known extractor hood, which represents a boxing, is in FIG. 4 shown. It follows that the eccentric screw elements ES must be introduced through openings in an upper projection ÜS of the rear wall of the fan box LK. In addition, an opening for a security element SE, in particular a locking screw is shown in the lower region of the rear wall of the fan box LK. The fan box LK is disguised after assembly of a telescopic channel KA, which is also referred to as a fireplace.

In addition, fastening devices for extractor hoods from the prior art are known in which support profiles or mounting plates are used. For example, the DE 10 2012 016 630 A1 an extractor hood with a hood body, inside which a fan is arranged. Furthermore, the hood body is assigned a support profile, which is releasably connectable to the hood body. According to one embodiment, the support profile forms a flat surface section. At its upper edge, the support profile has two projections which initially project in the direction of the hood body and form a hook. Lateral projections engage in slots or fits of the hood body, while a shoulder-like projection supports a shoulder of the hood body. Furthermore, obliquely extending slots are arranged as openings in the upper region of the support profile, can be guided by the fastening means in the form of screws.

Furthermore, in the DE 10 2011 051 104 B2 discloses an extractor hood for a stove, a hotplate or the like. The extractor hood preferably comprises a lower housing designed as a housing in the radial fan are arranged with a filter attachment. The rear wall of the housing is fixed to a wall surface with wall hooks which engage in slots on the rear wall of the housing. According to one embodiment mounting plates are provided for fixing the housing to a wall. The single mounting plate here in each case comprises two upper hooks and two lower hooks. The upper hooks have a degree of engagement which corresponds approximately to the material thickness of the rear wall of the housing. The lower hooks have an engagement dimension, which has clearance for tilt adjustment.

Finally, the reveals EP 2 119 970 A2 a mounting system for mounting a wall mountable housing of an extractor hood and method for securing a related housing. The mounting system comprises a mounting bracket which can be fastened to a wall and a housing that can be detachably fastened to the mounting bracket, namely a housing for a firewall. The mounting bracket has wall elements which can be arranged on the wall, each having a borehole opening. Furthermore, the mounting bracket has laterally arranged holding elements which engage in recesses arranged on the rear side of the housing and which are formed by slots in rear wall regions of the housing. The holding elements are wing-like, at right angles from the wall elements wegstreckende areas of the mounting bracket.

A generation of extractor hoods, in which instead of the box-shaped viewing hood, a sloping viewing hood, which is also referred to as Wrasenschirm is used is referred to as skew. To reduce the manufacturing cost and improve the visual appearance, construction is not so high. As a result, on the one hand, a lower use of material and less need for packaging material can be achieved.

In the case of extractor hoods, which are designed as air circulation hoods, that is to say only operated in recirculation mode, the provision of a chimney is not necessary. In these cooker hoods, the air is cleaned via grease and carbon filter and blown without further piping from the hood to the ceiling back to the room in which the hood is operated.

In particular, with circulating hoods, which are designed as skewed, is covered by the inclination of the Wrasenschirms, which may for example consist of a plate, in particular glass plate, the fan box from the front optically completely covered. Therefore, no further structures such as wall mounting should be visible above the fan box.

The invention is therefore an object of the invention to provide a hood with wall mounting device, which allows for a simple and secure attachment of the fan box to the mounting wall and on the other hand allows a good visual appearance of the hood.

The invention is based on the finding that this object can be achieved by an adapter element is used, which is between the back of the fan box and the room wall to which the hood is to be attached, and is detachably connected to the fan box.

The object is therefore achieved by an extractor hood, which has a fan box, which has at least one mounting opening in the back. The extractor hood is characterized in that the extractor hood comprises an adapter element which rests with the front on at least a part of the back of the fan box, that the adapter element has a base surface, that at least one attachment projection is arranged on the base, extending from the base extends at least partially forward, and that in the base at least one screw hole is introduced, wherein the adapter element is made of sheet metal and at least one of the Einhängevorsprünge represents a tab which extends from the base of obliquely upward, and at least one of the Einhängevorsprünge one upwards directed arm which is at least partially offset to the base of the adapter element forward, the arm is in the region of the free end parallel to the base and the transition from the offset to the base area to the base d A region of the arm which slopes upwards from the base surface is formed such that three suspension projections are provided on the adapter element, two arms being provided in the upper region of the adapter element and one lug being provided in the lower region of the adapter element.

As an extractor hood according to the invention preferably an extractor hood is called, which has a fan box. The extractor hood can also be called an Esse. As a fan box, the housing is referred to, in which the fan of the hood is included. The fan box preferably has a rectangular shape and has at least a back, side walls, a lid and a bottom. These areas of the fan box are preferably designed as walls, for example made of sheet metal. The front of the fan box may also be formed as a wall. However, the fan box has an inlet opening on one of the walls. The wall in which the inlet opening is formed may optionally be completely recessed. For example, it is possible with skewed out the front of the fan box and there to provide a Wrasenschirm. Alternatively, the bottom of the fan box may have the inlet opening or be recessed to form the inlet opening. In this case, the vapor shield is arranged on the underside of the fan box.

Directional information, such as front, back, top and bottom refer - unless otherwise stated - on the hood and its parts in the mounted on the room wall condition. The room wall to which the extractor hood is attached is also referred to below as the mounting wall.

According to the invention, the fan box has at least one fastening opening in the rear wall. The attachment opening may, for example, constitute an opening punched into the rear wall of the fan box. The attachment opening preferably has a rectangular shape. Particularly preferably, at least two fastening openings are provided in the upper region of the rear wall of the fan box. More preferably, at least one additional attachment opening is provided in the lower region of the rear wall of the fan box. The mounting holes are used to attach the fan box to an adapter element. In particular, the fastening devices serve to hook the fan box to the adapter element.

The extractor hood according to the invention comprises an adapter element. The adapter element is detachably connected to the fan box and serves to attach the hood to a mounting wall. For this purpose, the adapter element is first attached to the mounting wall and then the fan box connected to the adapter element. In the state in which the fan box is connected to the adapter element, the adapter element rests with its front side on at least part of the rear side of the fan box. As an adapter element, a flat, planar element is preferably referred to, which may represent a sheet, for example. The adapter element has a base. With the back of the base, the adapter element is in the mounted on the mounting wall state, preferably on the mounting wall. At least one attachment projection is arranged on the base surface. The suspension projection extends at least partially from the base to the front. The suspension projection is used to engage with the mounting hole on the fan box. As a hanging projection tabs, arms, hooks and the like can be used. In the base area at least one screw hole is further introduced. The screw hole serves to pass through a fastening means, in particular a screw, by means of which the adapter element is fastened to the mounting wall.

By an adapter element is provided in the extractor hood according to the invention, which is releasably connected to the fan box and can also be attached to the mounting wall, the assembly of the hood is simplified on the mounting wall. In particular, the adapter element can be screwed to the mounting wall via the at least one screw hole. Since the fan box is detachably connected to the adapter element, this screwing the adapter element can be done on the mounting wall, when the fan box is not yet connected to the adapter element. Subsequently, the hood can be hung on the fan box on the adapter element and thus secured and is mounted on the mounting wall.

According to a preferred embodiment, the height of the adapter element is equal to or smaller than the distance between the lid, that is top, and bottom, that is bottom, of the fan box. If the bottom is recessed on the fan box and a vapor shield is provided on the underside of the fan box, the height of the adapter element in this embodiment is smaller than the distance between the lid and the bottom of the fan box. The width of the adapter element is preferably smaller than the width of the fan box. By the size of the adapter element is smaller than the size of the fan box, in particular the rear wall of the fan box, the adapter element in the mounted state of the hood can be completely covered by the fan box and is thus for the user Extractor hood not visible. But by the fan box is releasably connected to the adapter element, the access to the adapter element, in particular for attachment to the mounting wall or for releasing the mounting wall, can be ensured.

According to the invention, the adapter element is made of sheet metal and at least one attachment projection represents a tab and / or an arm. The use of a metal sheet for the adapter element simplifies the production of the extractor hood. In particular, the suspension projections can be formed by stamping, punching and / or bending from the sheet metal. By the Einhängevorsprünge thus are integral with the base, also the stability and thus the maintenance of the hood are improved. There are provided on the adapter element differently shaped Einhängevorsprünge. There are provided a tab in the lower region of the adapter element and two arms designed as Einhängevorsprünge in the upper region. In this case, a tab is understood to be a strip of material which projects forward at an angle to the base surface and extends straight. An arm is referred to as a strip of material which, at a first angle to the base surface, protrudes forwards towards it and continues in a part which lies at a second angle to the base surface. The tab or the arm can be made by punching and bending in an adapter element made of a sheet metal.

According to the invention, at least one attachment projection is a tab which extends obliquely upward from the base surface. For example, the tab may be at an angle in the range of 20 ° to 45 °. By an upwardly inclined Einhängevorsprung the fan box is automatically moved to the base after insertion of the tab into a mounting opening of the fan box by the weight of the fan box by sliding down the tab and the probability of jumping out can be reduced. In particular, the jumping out, as will be explained in more detail later is prevented by attaching a locking screw on the lid of the fan box.

According to the invention, at least one suspension projection is an upwardly directed arm, which is offset in the region of the free end to the base of the adapter element to the front. The area of the free end of the suspension projection is parallel to the Base. The transition from the area lying offset to the base area to the base area is formed by an area of the arm inclined upward from the base area. Due to the inclination, an automatic movement of the fan box on the base can be realized when the arm is inserted into a mounting opening of the fan box. In addition, the embodiment of the suspension device as an arm has the advantage that the area of the suspension device, which is preferably offset in parallel to the base area, is suitable for absorbing weight. The arm can therefore be used at its free end for supporting the fan box from the inside. In the staggered region, embossments for reinforcement can additionally be introduced into the arm. Additionally or alternatively, the arm can also serve to secure against unhooking the fan box. However, according to a preferred embodiment, the arm has a length which is less than the distance of the upper edge of an upper attachment opening to the lid of the fan box. In this embodiment, the fan box is thus not upon insertion of the arm in the mounting hole on the arm, but the arm extends to just below the lid. If, in this embodiment, a locking screw is guided through the cover and a fastening web on the arm, the fan box is pressed firmly against the adapter element and thus against the mounting wall. This pressing against the adapter element and the mounting wall is aided in that the suspension projections are preferably inclined, for example, represent inclined tabs or arms with an inclined transition region.

According to a preferred embodiment, at least one fastening web is provided on at least one suspension projection of the adapter element. The fastening web is provided in particular at the free upper end of the suspension projection. The fastening web protrudes at the upper edge of the suspension projection from the suspension projection to the front and is located in the mounted state of the hood on the inside of the lid of the fan box. Through the fastening web a connection surface is created, on the one hand, the support of the fan box is supported on the suspension device. In particular, the attachment web additionally serves to rest the upper edge of the attachment opening on the attachment projection in order to improve the hold of the ventilation box on the adapter element. On the other hand, in the fastening web a screw opening can be introduced, via which the fan box from above through the lid of the fan box with the suspension device can be screwed. Since the fastening web rests on the inside of the underside of the lid of the fan box, the locking screw is preferably screwed from above through a screw opening provided in the cover and the fastening web and thus connects the fastening web with the cover. The attachment web may be provided on a suspension device which constitutes a tab or on a suspension device which constitutes an arm.

According to a preferred embodiment, the at least one screw hole is arranged in the base area adjacent to the at least one attachment projection. As a result, the forces acting on the suspension projections can be transmitted without great leverage on fastening means, in particular screws, which are guided by the screw holes and fasten the adapter element to the mounting wall. Particularly preferably, a screw hole is arranged adjacent to each suspension projection.

According to a preferred embodiment, at least one of the screw holes is a slot. The slot can be aligned vertically or horizontally. Particularly preferably, at least one slot is horizontal and at least one slot vertically aligned. By the screw holes represent slots, the adapter element can be easily aligned when mounted on the mounting wall.

According to the invention, three suspension projections are provided on the adapter element, wherein two arms are provided in the upper region of the adapter element and a tab is provided in the lower region of the adapter element. This configuration of the adapter element, the arms can be used for hanging and in addition to supporting the fan box from the inside up. By the hanging projection at the bottom of a tab, the mounting of the hood is further simplified, since the tab can be easily inserted into the mounting hole of the fan box.

According to a preferred embodiment, the extractor hood is a bevel or vertical Esse, which is also referred to as Flat-Esse, represents. In the Schrägesse the fan box is open to the front and the Wrasenschirm is mounted inclined to the front. For vertical food is the suction of the hood in the vertical, that is parallel to the mounting wall, on the front of the hood. In these types of extractor hoods, the advantages of the present invention can be used particularly since usually no cladding, such as a chimney is provided around the fan box and a connected only at the back of the fan box adapter element is not visible in the extractor hood according to the invention.

The invention will be further described with reference to the accompanying figures.

In the fan box 10, a fan 13 is accommodated, the outlet nozzle 130 protrudes through the lid 101 of the fan box 10. The vapor shield 11 is mounted inclined forward on the front of the fan box 10. In the illustrated embodiment, the vapor shield 11 is configured with a baffle plate 110 in the intake opening of the extractor hood 1.

In the rear wall 100 of the fan box 10 mounting holes 1000 are introduced, of which in FIG. 1 only one can be seen in the upper area and one in the lower area of the rear wall 100. The mounting holes 1000 have a rectangular shape. Hanging devices 121, 126 of an adapter element 12 engage through the attachment openings 1000.

The adapter element 12 is in FIG. 2 shown in more detail. The adapter element 12 has a base area 120 which, in the illustrated embodiment, widens upwards from a narrow strip as a lower area and ends in a wider upper area. Attachment devices 121, 126 are formed on the adapter element 12. The suspension devices 121, 126 are arranged on the base surface 120 and protrude from the base 120 to the front.

In the illustrated embodiment, a tab 121 is provided as a suspension device in the lower region of the adapter element 12. The tab 121 represents a piece of material made of the material of the base 120 of the adapter element 12 and is bent forward out of the base 120. The tab 121 is inclined upwards. Below the tab, a screw hole 122 is inserted into the base 120. In the illustrated embodiment, the screw hole 122 forms a horizontally extending slot. Through this screw hole 122 a mounting screw 124 can be passed and the adapter element 12 thereby on a mounting wall 2 (see FIG. 3 ) are attached.

In the upper region of the adapter element 12, in particular on the upper edge, two further Einhängevorsprünge are provided which are formed as arms 126. The arms 126 are offset with their upper portion to the base 120 forward and are in this area parallel to the base 120. In the upper portion of the arms 126 vertical embossments are introduced. At the free end of the arms 126, that is at the upper end of the arms 126, a fastening web 123 is provided in each case. This extends from the arm 126 to the front and lies in the horizontal. Below the arms 126, a screw hole 122 is provided in each case. These screw holes 122 are formed in the illustrated embodiment by vertically extending slots. By means of these screw holes 122, a mounting screw 124 can be passed in each case and the adapter element 12 can thereby be fastened to a mounting wall 2.

In FIG. 3 is a schematic diagram of the hood 1 shown according to an embodiment of the present invention, based on which now the assembly of the hood 1 should be described again. In a first step, the adapter element 12 is screwed to the mounting wall 2. This is schematically illustrated by the mounting screw 124 in the lower portion of the adapter element in FIG FIG. 3 shown. In addition, the adapter element 12 but also by other mounting screws 124 (see FIG. 2 ) in the upper area (in FIG. 3 not shown) attached to the mounting wall 2. In the fastened state of the adapter element 12, the suspension projections 121, 126 project forward beyond the base surface 120 of the adapter element 12 and the rear side of the base surface 120 bears against the mounting wall 2.

The fan box 10 of the extractor hood 1 can now be attached to the adapter element 12 mounted in this way. For this purpose, the fastening openings 1000 in the rear wall 100 of the fan box 10 are aligned with the suspension projections 121, 126. Subsequently, the fan box 10, as indicated by the arrow in FIG. 3 indicated, moved toward the adapter element 12. In this case, the suspension projections 121, 126 engage with the fastening openings 1000, that is, are inserted into them. Due to its own weight, the fan box 10 then slides downwards along the upper sides of the suspension projections 121, 126, until the rear side of the fan box 10 bears against the front side of the adapter element 12, in particular the base surface 120. In this state, the insertion projection formed as a tab 121 protrudes obliquely upward into the interior of the fan box 10. The vertically extending upper portion of the arm 126 preferably lies against the rear wall 100 of the fan box 10 from the inside. In addition, the horizontally extending fastening web 123 rests from the inside on the cover 101 of the fan box 10. The fastening web 123 is arranged on the upper edge of the suspension projection designed as an arm 126 and protrudes from the arm 126 to the front. The arm 126 and in particular the fastening web 123 thus support the fan box 10 in addition. The adapter element 12 is thus detachably connected to the fan box 10.

Preferably, in a further step, a locking screw 125 through the lid 101 of the fan box 10 and one provided in the fastening web 123 Screw opening 1230 (see FIG. 2 ) and the arm 126 is bolted to the fan box 10.

The present invention thus provides a simple yet reliable way of attaching a cooker hood to a mounting wall, also referred to as a room wall. Preferably, an adapter element, which represents a metal sheet and therefore can also be referred to as an adapter plate or suspension plate, is screwed to the room wall, thereby aligned and then the extractor hood is hung from it. By means of the preferably provided two locking screws over which the arms are attached to the cover of the fan box, the fan box is secured against levers. When screwing to the mounting wall, preferably only the two upper mounting screws are attached. Then the suspension plate is aligned. The mounting screws sit as close to the Einhängevorsprüngen, in particular a tab and two arms to ensure the most stable possible seating of the fan box on the wall.

An advantage of the present invention is that it is possible due to the mounting method, the adapter element to be dimensioned so that is no longer visible from the parts for wall mounting after attaching the hood. The handy adapter element, which is preferably a suspension plate, is easy to handle and align when screwed to the mounting wall. The mounting screws are still easily accessible to the user. In particular, the entire extractor hood no longer has to be aligned with adjusting screws or with eccentrically rotating plastic cylinders, as is the case in the prior art. Thus, in the design, the accessibility to a lower locking screw, which is required in the prior art, no longer be considered. Securing the extractor hood against prying done according to the invention preferably not by the spatially very close screwing the hood directly to the wall but by two easily accessible locking screws that can be screwed from above through the lid of the fan box in the suspension plate.
