Description

The present invention relates to an extractor hood with a lighting device.

Cooker hoods are usually mounted above stove. In order to better recognize the cooking zones of the cooker or the food that is prepared in pots or pans lighting devices are provided in some hoods, which are integrated in the cooker hood. Such a lighting device is for example in the DE 102 08 488 A1 described. In this hood, the lighting device is provided on the rear side of the hood on the underside of the hood. Furthermore, in US 2006/025 0799A1 describes a lighting and control unit on an extractor hood. This is included in the front of the cooker hood. If the lighting and control unit is pivoted forwardly out of the front, the hob under the extractor hood can be illuminated by means of lamps which are accommodated in the underside of the lighting and control unit.

A disadvantage of these known extractor hoods with lighting devices is that the area that can be illuminated by the lighting device is fixed.

The invention is therefore based on the object in a simple way to provide a variable illumination of a hob or lying under a fume extractor surface.

The object is achieved by an extractor hood with a lighting device. The extractor hood is characterized in that the illumination device comprises a fastening device for fastening at least one illumination module and the fastening device has a receiving region whose length is greater than the width of the at least one illumination module.

For the purposes of the invention, an extractor hood is preferably understood to be a food, in particular a wall or island food. The extractor hood can also be configured as a flat-screen hood or under-hood.

As a fastening device according to the invention a device understood by which at least one lighting module can be attached to the hood. The receiving area of the fastening device represents the part of the fastening device in which at least part of at least one lighting module is received and via which the lighting module is connected to the fastening device and thus to the extractor hood. According to the invention, the receiving area is designed in such a way that at least one lighting module can be freely positioned in it. The receiving area therefore preferably represents a continuous area or a continuous space. The receiving area also has, at least in the length, a larger dimension than the dimension of the illumination module, in particular a connecting area of the illumination module. The lighting module according to the present invention is a module in which all the components required for generating light are contained and which outputs light when supplied with voltage. Thus, at least one light source and optionally optical elements and current or voltage connections are provided in the illumination module. Within the meaning of the invention, the area of connection or region of the surfaces through which the illumination module is in contact with the fastening device in the installed state is understood as the connection region of the illumination module.

By the receiving area for the illumination module (s) having a larger dimension, in particular greater length, than the width of the illumination module, the illumination module or preferably the illumination modules can be freely positioned in the receiving area along its length. For the purposes of the invention, free positioning is understood to mean the positioning of the illumination module in at least two positions in the receiving area. According to the invention, the at least one lighting module can be freely positioned along the length of the receiving region of the fastening device. This means that the lighting module can optionally be used at different locations along the length of the receiving area and connected to the fastening device via it. The length of the receiving area of the fastening device preferably represents the largest dimension of the receiving area Particularly preferably, the length of the receiving area is parallel to the width of the extractor hood. The width of the illumination module, in particular in the connection region, represents the dimension which, in the mounted state of the illumination module, lies parallel to the length of the reception region.

By the illumination module or the lighting modules in the receiving area can be fixed at different locations, the illumination of a surface located below the hood according to the wishes and current requirements of the user of the hood can be done. Conventional cooker hoods are usually provided for lamps lampholders. The lampholders correspond in their dimensions to the dimensions of the base of the lamp which is to be accommodated therein. Due to these lampholders, the positions of the lamps on the hood are thus fixed and can not be changed by the user. In the extractor hood according to the invention, however, the user can freely choose the position of the lighting modules within the receiving area.

Preferably, the receiving area serves for the detachable connection of the at least one lighting module with the fastening device. By the connection between the lighting module and the fastening device is solvable, the position of the lighting module can be changed by the user even after initial installation always. The detachable connection can be generated via latching or clamping devices. These are then arranged in the extractor hood according to the invention so that the clamping force acts in a direction which is inclined to the length of the receiving area, preferably perpendicular to the length of the receiving area. In particular, the holding force can act, for example, perpendicular to the length of the receiving area in the width direction of the receiving area. Particularly preferably, the connection between the lighting modules and the fastening device is such that the position of the lighting module or modules can be changed without disconnecting the connection. In particular, the lighting module or modules can be moved along the length of the receiving area. For this purpose, the receiving area preferably has connecting means which are continuous over the extent of the receiving area in the longitudinal direction. These connecting means can be formed for example by webs on which the lighting modules can be hung, hooked or snapped.

According to a preferred embodiment, the fastening device in the receiving area at least partially made of magnetizable or magnetic material. As a result of this configuration of the fastening region, the lighting module or the lighting modules can be fastened particularly easily at different positions in the receiving region. In this case, the lighting module in the connection region is correspondingly designed to be magnetic or magnetizable, whereby attachment of the lighting module to the fastening device can be achieved by magnetic force. The holding force in this embodiment is also preferably perpendicular to the length of the receiving area. In the simplest case, in this case, the receiving areas can represent a plane at which the lighting module or the lighting modules can be held with their rear side by magnetic force. An attachment via magnetic force has, inter alia, the advantage that the attachment or connection can be easily solved and also a simple movement of the lighting module is possible. In addition, the production of the lighting modules and the receiving area is simplified because a rest or Hack device does not need to be provided.

Preferably, the receiving area serves as a receptacle for at least two lighting modules. In this case, the length of the receiving area is preferably greater than the width of all introduced into the receiving area lighting modules. As a result, a displacement or other repositioning of the lighting modules in the receiving area can be ensured even if there are several lighting modules introduced into the receiving area. Alternatively, it is also possible that the length of the receiving area is dimensioned such that when introducing a maximum number of lighting modules in the receiving area, the entire length of the receiving area is covered by the connecting portions of the lighting modules.

The illumination modules are preferably designed such that they have a constant width over their height.

According to a preferred embodiment, the fastening device is a rail. As a rail in the context of the invention, a straight elongated profile Understood. Here, a flat profile or an open profile, for example in the form of an L-profile can be used. By the fastening device consists of a rail, at least one of the surfaces of the rails is available for the attachment of the lighting modules over the length thereof. Thus, one lighting module or multiple lighting modules over the entire length of the rail can be connected to this. The number of attachable to the fastening device lighting modules is thereby maximized.

According to one embodiment, the receiving region has two reception surfaces arranged inclined to each other. As recording surfaces, the surfaces of the receiving area are designated, which can at least partially come into contact with the connection region of the lighting module. If the fastening device is formed by an L-profile, the inner sides of the legs of the L-profile form the receiving surfaces of the receiving region, via which the illumination modules can be brought into contact with the fastening device. This creates a large contact area. In addition, in the case of this shape of the receiving region, a connecting force can be exerted on two surfaces of the lighting module which are offset relative to one another. As a result, the individual required connection forces can be reduced. When the illumination module is connected by magnetic force, for example, magnets of a lower magnetic force can be provided on the two limb surfaces of the receiving region than the magnetic force that would be necessary for attachment to a planar rail.

Preferably, the fastening device is pivotally connected to the extractor hood. In particular, the fastening device is arranged pivotably relative to the frame of a viewing screen of the extractor hood. The pivot axis of the fastening device is in this case preferably parallel to the direction of the length of the fastening device. This further increases the flexibility of adjusting the lighting of a surface below the extractor hood. In addition to a displacement or displacement of the lighting module or modules in the direction of the length of the receiving area, in this case also the inclination angle of the fastening device and thus of the lighting modules can be adjusted. Preferably, all lighting modules are attached to a fastening device and the pivoting of the fastening device thus leads to a change in the luminous angle of all lighting modules. However, it is also within the scope of the invention, several fastening devices provide, to each of which one or more lighting modules can be attached. In this case, then the individual fastening devices can be pivoted separately.

According to one embodiment, an actuating lever for pivoting the fastening device is provided on the fastening device. This actuating lever is preferably oriented so that it extends perpendicular to the length of the fastening device. Particularly preferably, the lever bears against a bearing on which the fastening device is rotatably mounted. The operating lever may extend forwards or downwards and project through, for example, a frame of the extractor hood or other trim. By means of the actuating lever, it becomes possible to set the desired position of the fastening device and thus of the lighting modules provided on the fastening device, without the user having to touch the lighting modules themselves.

Preferably, the fastening device is pivotable in at least two operating positions. Particularly preferably, the fastening device can be locked in these operating positions. The locking can for example take place via a frictional force which is generated at the bearing of the fastening device, via which the fastening device is connected to the extractor hood. The use of a friction force has the advantage that the fastening device can be pivoted continuously into a large number of operating positions. The operating position here is a position in which one or more lighting modules provided on the fastening device can illuminate a surface located below the extractor hood.

The fastening device is arranged according to an embodiment in the rear region of the underside of the extractor hood. The underside of the extractor hood is in this case formed, in particular in the case of food, generally by the underside of a viewing screen, in which a frame is arranged which surrounds the suction opening. The arrangement of the fastening device in the rear region of the underside of the extractor hood has the advantage that, in particular with cooker hoods whose suction surface is inclined from the horizontal upwards, the illuminable angle is not affected by the hood itself. In addition, in this arrangement, the lighting device, the illumination of the underlying surface of the hood by actions of the User, such as stirring, not or at least less affected than in an arrangement of the lighting device in the front region of the underside of the hood.

According to a preferred embodiment, the fastening device comprises a current guide, by means of which the one or more lighting modules can be supplied with voltage. By the power supply for the lighting modules via the fastening device, for example when using a current-carrying rail, the fastening device can be arranged to be movable relative to other parts of the hood. The power supply to the fastening device can be done for example via the bearings on which the fastening device is connected to other parts of the hood.

The fastening device preferably comprises a low-voltage supply. The low-voltage supply in particular comprises poles for connecting the at least one lighting module. The low voltage suitable lighting modules can be supplied with sufficient voltage for lighting. However, with this power supply, a danger to the user of the hood is not to be feared. Thus, the contacts or poles of the power supply can be freely present in the receiving areas. This further simplifies the construction of the extractor hood.

The at least one illumination module preferably comprises at least one light-emitting diode (LED) and a housing. The voltage required for illumination by LEDs can be supplied by a low voltage supply and thus the above advantages can be achieved. In addition, a uniform illumination of the surface located below the extractor hood can be generated by the use of LEDs. Optic elements are preferably additionally provided in the housing in the illumination module in this embodiment.

According to one embodiment, the extractor hood for receiving at least one wedge-shaped lighting module on a fastening device in the form of an L-shaped rail which is rotatably mounted about a pivot axis, and the length of the fastening device corresponds to the width of the extractor hood. In this embodiment, the flexibility of adjusting the illumination of a surface below the extractor hood is maximized. On the one hand, the largest possible number of lighting modules can be flexibly positioned over the length of the fastening device and, on the other hand, the illumination angle can be set by pivoting the rail.

A number of advantages can be achieved with the present invention. In addition to the increased flexibility of setting the illumination of a surface below the hood, the operation and handling of the lighting device is easy. In particular, by providing a fastening device for at least two illumination modules, an illumination angle can be adjusted by moving the fastening device. The user does not need to touch the individual lighting modules and the user therefore does not have to wait until the lighting elements, which may have been heated by use, have cooled down in order to be able to adjust them. In addition, by the variable insertion of lighting modules in the present invention, the horizontal illumination distribution can be adjusted individually. Finally, due to the simple design of the fastening device lighting module can be used by a simple design, which can optionally be used on other household appliances. These other household appliances, which may represent refrigerators, for example, require only a corresponding receiving area for the lighting modules. Since the receiving area can be embodied according to the invention simply, for example, can represent the insides of an L-profile or a side of a planar profile, the provision of the receiving area on other household appliances can be easily realized. Thus, a modular replacement of lighting modules between household appliances is possible, thus further increasing the flexibility.
