Definitions

• the present invention relates to a housing for an extractor hood, in particular for a flat screen hood, and to a fan holder for a ventilation device of an extractor hood, in particular for at least one fan
• ventilation devices in particular fans, are provided, by means of which a flow is set in the extractor hood, which serves to extract vapors and vapors, which can arise, for example, during cooking.
• the ventilation devices are accommodated in fan containers, in particular in fan housings, for example in the form of screw housings.
• the fan container which can be fastened to a base plate, generally has a suction opening, which also extends through this base plate when a base plate is present, and an outlet opening which is provided on the top of the fan container in the case of vertical radial fans.
• a housing is provided on extractor hoods.
• This housing for example, together with the base plate, can be used to create a guide channel for the air to be discharged to the suction opening of the fan container.
• the housing of the extractor hood generally serves to receive the fan container in order to prevent contamination of the container or of lines that run to or from the container.
• housings of extractor hoods consist of several individual parts, which are connected to one another, for example, by screw connections.
• the individual parts of the housing generally include a cover, which may have a passage for the outlet opening of the fan container, and two side walls, a rear wall and a front cover.
• the object of the present invention is therefore to provide a housing for an extractor hood and a fan container for a ventilation device of a Durist extractor hood, which can be manufactured simply and inexpensively and allow simple and inexpensive assembly and disassembly of these parts and thus the extractor hood.
• the present invention is based on the knowledge that at least individual parts of the housing or the fan container can serve multiple functions.
• the object of the present invention is therefore achieved according to a first aspect by a housing for an extractor hood, wherein the extractor hood has at least one fan container and the housing serves to accommodate at least a part of the fan container.
• the housing is characterized in that a section of an outer wall of the housing is formed by part of the fan container.
• the fan housing is the fan housing in which one or more fans of an extractor hood run.
• fan containers can therefore represent, for example, the housing of a radial fan, a screw fan housing or the like.
• housing of the extractor hood is understood to mean the housing in which the fan container is at least partially accommodated and which therefore serves at least to cover a part of the fan container and, if appropriate, further elements, such as cables.
• the housing can also serve to form the space in which the vapors and vapors to be removed are led to a suction opening of the fan container.
• part of the fan container as a section of an outer wall of the housing, no separate housing part is necessary for this section.
• the number of individual parts of the housing and their size can thus be reduced, as a result of which the manufacturing and assembly costs can also be reduced.

• the outside of the fan container can be used as part of the housing.
• the outlet connection must always protrude from the housing for the extractor hood for connection to an exhaust pipe or for the inlet into an exhaust duct, so that the area around the outlet connection of the fan can easily be used as a section of the top of the housing for the extractor hood ,
• the part of the fan container which forms a section of the outer wall of the housing preferably has the shape of a plate.
• a plate is a part of the fan container that has an essentially flat surface.
• the housing comprises two side walls, at least part of one of the side walls forming a section of the top of the housing.
• At least one of the side walls of the housing By designing at least one of the side walls of the housing in such a way that it simultaneously forms at least part of the top of the housing, the area that must be covered by a further component on the surface can be reduced.
• At least one of the side walls preferably has an angled area on its upper edge. This angled area can be used to form the top of the housing.
• the angled region is preferably configured in one piece with the side wall.
• Such a side wall can be produced, for example, by bending. Due to this simple production of a side wall, which at the same time forms at least a section of the upper side of the housing, the production costs can be reduced compared to a housing in which the side wall forms exclusively the side of the housing and a cover is screwed onto the side wall for covering the upper side got to.
• At least a part of the region of the side wall, which forms a section of the upper side of the housing can be brought into engagement with at least a region of the fan container.
• This engagement preferably results in a positive connection between the side wall and the fan container.

• a rear wall of the housing can also be brought into engagement with the fan container in the region of the top of the housing.
• the engagement is preferably a positive connection, which enables the rear wall to be fastened directly to the fan container. This eliminates the need to screw the rear wall onto another part of the housing, for example the side walls of the housing. The assembly is therefore made considerably easier.
• the engagement of the rear wall with the fan container can take place, for example, over an angled area provided on the rear wall. This angled area can be configured, for example, in the form of a flange.

• the provision of engagement devices for housing parts on the fan container creates a simple way of fastening the housing parts.
• the engagement device preferably comprises at least one receiving area for part of a side wall and / or rear wall of the housing.
• the fan container preferably has at least one plate-shaped area on its upper side.
• This plate-shaped area can be used as a section of the outer wall of the housing for the extractor hood. Furthermore, the plate-shaped area can simultaneously represent at least part of the engagement device for further housing parts.
• the plate-shaped area on the fan container is preferably designed such that it extends from the outlet connection of the fan container over at least part of the width and depth of the housing for the extractor hood. This plate-shaped area can therefore form at least a section of the upper side of the housing and is formed in one piece with the fan container, which makes assembly easier.

• the present invention thus requires only two side walls, which together with the fan container form the cover, in particular when parts of the cover are integrated into the fan container.
• the provision of a separate cover part can therefore be omitted. It is therefore no longer necessary to screw side parts to a cover.
• the present invention therefore increases the assembly time of the housing of the extractor hood and thus of the entire extractor hood shortened. Furthermore, the number of parts required to assemble the housing is reduced, since a separate cover part can be omitted. Finally, screws are also saved since they can be dispensed with for connecting the side walls to the fan housing to form the upper side and for connecting the side parts to the rear wall.
