Description

Wall and/or ceiling cooker hood with light projection

Technical Field

The invention relates to a wall and/or ceiling cooker hood, in particular for kitchens.

Background

At least one wall and/or ceiling hood is typically arranged in the kitchen (mostly above the kitchen range) in order to suck away the cooking fumes generated during the cooking process. Here, wall and/or ceiling hoods typically have a relatively exposed position in the kitchen. In addition, users typically spend more time at or near wall and/or ceiling hoods while cooking.

Disclosure of Invention

The technical task of the present document is to improve the user comfort of a domestic appliance at home, in particular when monitoring the condition or state of the domestic appliance.

This object is achieved by the subject matter of the independent claims. Advantageous embodiments are defined in particular in the dependent claims, are described in the following description or are shown in the drawings.

According to one aspect of the invention, a wall and/or ceiling-mounted range hood is described, which can be mounted, for example, to the wall and/or ceiling of a kitchen, for example, above a cooktop. Wall and/or ceiling hoods typically comprise a suction module which is provided to convey air via a suction region into the housing of the wall and/or ceiling hood until the suction region is reached. Cooking odours and/or grease can thus be sucked away from the surroundings of the hob.

A wall and/or ceiling cooker hood includes a housing. In this case, the housing can have a suction region with a larger cross section, which typically faces the cooking hob in the installed state of the wall and/or ceiling hood. Due to the large cross section, it is possible to suck soot from a wide environment of a wall and/or ceiling hood. Furthermore, the housing typically comprises an extraction region which faces away from the cooking hob for the most part and which typically has a small cross section, for example in order to divert (filtered) soot into the extraction duct and/or to blow it out again into the surroundings. In addition, the housing also typically includes a transition region (where the cross-section becomes smaller) extending therebetween.

Furthermore, the wall and/or ceiling hood comprises at least one lighting unit with a plurality of individually controllable lighting elements. The lighting unit is arranged here (in particular in the transition region) such that a light image can be projected by the lighting unit onto the wall behind the wall and/or ceiling hood and/or onto the ceiling above the wall and/or ceiling hood. The lighting unit is preferably arranged at the housing of the wall and/or ceiling ventilator in such a way that, in the installed condition of the wall and/or ceiling ventilator, the lighting unit is covered by the housing, in particular by the suction area, and therefore the lighting unit is not visible to the user of the wall and/or ceiling ventilator.

The lighting unit may be arranged to project a light image, which may be detected by a user from a distance of 2 meters, 3 meters, 5 meters or more than 5 meters. Here, the lighting unit 10 may comprise 10, 20 or more lighting elements on the one hand and/or 200, 100 or less lighting elements on the other hand. The individually controllable lighting elements can be arranged, for example, in one or more rows. The individually controllable lighting elements may alternatively or additionally be arranged in a matrix with a plurality of columns and a plurality of rows. The lighting unit may thus be arranged to project a more complex light image (e.g. a pattern, a line, a sign, a symbol, etc.) onto the wall and/or on top. On the other hand, the illumination unit typically has a smaller pixel resolution and is therefore capable of cost-effectively displaying light images.

The wall and/or ceiling hood furthermore comprises a control unit which is provided to determine data for the light image to be projected and to control the lighting unit as a function of said data. The control unit can be provided, in particular, for ascertaining state information relating to an appliance and actuating the lighting unit as a function of the state information in order to project a light image which reproduces the state information. The control unit can be provided, for example, for determining status information relating to the status of the wall and/or ceiling hood (for example relating to the suction level of the suction module).

In a preferred example, the wall and/or ceiling hood comprises a communication unit which is provided to receive data via a communication link, in particular via a wireless communication link. The control unit may then be provided for receiving (and displaying by means of a light image) status information relating to another household appliance via the communication unit.

A wall and/or ceiling hood is therefore described, which can be used to display status information relating to one or more household appliances, in particular household appliances, and thus can improve the comfort of the user when monitoring the household appliances.

The intensity and/or color of the individually controllable lighting elements can be changed if necessary. The lighting elements may comprise or be RGB (red, green, blue) -LEDs (light emitting diodes), for example. The control unit can be provided for determining, for a plurality of lighting elements of the lighting unit, data relating to the intensity and/or color of the lighting elements for the light image to be projected. The complexity and information content of the light image shown can be increased.

The wall and/or ceiling hood may comprise a user interface enabling a user to determine which data should be displayed in the projected light image. For example, the user may be enabled to select an appliance about which status information should be displayed. The comfort in monitoring the household appliance can thus be further increased.

The user interface of the wall hood and/or ceiling hood may not have its own display (e.g., no own screen) if necessary. Alternatively or additionally, the display of the user interface may be provided by the lighting unit. In particular, a display of the user interface may be provided by the projected light image. The costs and installation space of the wall and/or ceiling hood can thus be reduced.

The control unit may be arranged to determine emotional information relating to an emotional state of the user (e.g. via a user interface of a wall hood and/or a ceiling hood). Furthermore, the control unit may be arranged for causing the lighting unit to project a light image related to the mood information. By taking into account the emotional state of the user in the light image to be projected, the comfort of the user can be further improved.

It is to be noted that each aspect of the wall and/or ceiling cooker hoods described in this document can be combined with each other in a multiplicity of ways. In particular, the features of the claims can be combined with one another in a multiplicity of ways.

Detailed Description

As stated at the outset, this document deals with improving the comfort for the user of a domestic appliance in the home. In this context, fig. 1a and 1b show a wall hood 100 (as an example of a wall hood and/or a ceiling hood), which may be arranged, for example, in a kitchen of a home. Wall and/or ceiling hoods may also be referred to as range hoods. A wall hood 100 is typically fixed to a wall 110 and a ceiling hood is fixed in a corresponding manner to the ceiling of a room. The aspects explained in this document for the wall hood 100 apply in a corresponding manner to the ceiling hood.

The wall hood 100 typically comprises a suction region 101 which faces, for example, the cooktop and through which cooking fumes can be sucked from the cooktop into the wall hood 100. At the housing wall of the suction area 101, a user interface 108 can be arranged, which enables a user to adjust the level of the suction module 104 and/or to activate a lighting device (not shown) of the wall hood 100, for example.

In addition, the wall hood 100 typically includes an extraction area 103 through which the drawn-in cooking fumes can be transported away from the wall hood 100. The extraction area 103 typically faces away from the cooktop. Furthermore, the extraction region 103 typically has a reduced cross section compared to the suction region 101, so that the flow velocity of the soot is higher in the extraction region 103 than in the suction region 101.

The wall extraction hood 100 typically has a transition region 102 between the suction region 101 and the extraction region 103, in which the cross section of the wall extraction hood 100 decreases from a larger cross section of the suction region 101 to a smaller cross section of the extraction region 103. The transition region 102 for this reason typically has a surface which is at least partially oriented towards the roof of the room.

The wall ventilator 100 may comprise a control unit 105 arranged to control the suction module 104 (e.g. a fan) of the wall ventilator 100 in dependence of a user input at the user interface 108 (e.g. in dependence of a selected suction level). Furthermore, the wall ventilator 100 comprises a communication unit 106, which is provided to receive or transmit data via a (wireless) communication connection (e.g. WLAN or bluetooth).

Fig. 1a shows the wall hood 100 in a front view (perpendicular to the wall 110) and fig. 1b shows the wall hood 100 in a side view (parallel to the wall 110).

The wall hood 100 has one or more lighting units 107 in the transition region 102, which are provided to project light onto the ceiling and/or the wall 110. In the case of a square wall range hood 100, the transition region 102 has, for example, three sides, two of the sides extending away from the wall 110 into the room, and the other side extending parallel to the wall 110 and the two other sides being connected to one another. The wall hood 100 can have one or more lighting units 107 at one or more faces of the transition region 102, respectively.

Fig. 2a and 2b show an exemplary lighting unit 107. The lighting unit 107 comprises a plurality of lighting elements 201 (e.g. between 10, 20 or 50 on the one hand and 50 or 100 on the other hand). Here, each lighting element 201 may be individually activated or deactivated. Furthermore, the intensity of the lighting element 201 may be individually adjusted as necessary (e.g. between 0% and 100% in a plurality of levels (e.g. 10, 20, 50 or more levels)). Furthermore, the color of the lighting element 201 may be individually adjusted if necessary. The lighting element 201 may for example comprise or be an RGB-LED.

The lighting elements 201 of the lighting unit 107 may be arranged along a straight line, for example as shown in fig. 2 a. The lighting elements 201 of the lighting unit 107 may alternatively or additionally be arranged in a matrix shape as shown in fig. 2 b.

The lighting unit 107 can thus be provided for projecting a light image 301 onto the wall 110 and/or the ceiling of a room by individually actuating the lighting elements 201 (see fig. 3).

The control unit 105 can be provided to determine the information that is to be reproduced in the respective one or more light images 301 by the one or more lighting units 107 of the wall hood 100. For example, status or state information relating to the status of the wall hood 100 (for example relating to the suction level) can be reproduced. Information, for example, status or state information, may alternatively or additionally be received from another household appliance by means of the communication unit 106 and reproduced in the light image 301. The one or more light images 301 are visible to the user from a distance and thus enable a comfortable monitoring of the condition or status of at least one household appliance in the home.

Fig. 4 shows a flow chart of an exemplary method 400 for providing status or state information relating to a status or state of a home appliance. The method 400 may be implemented by the control unit 105 of a wall hood and/or a ceiling hood 100. The method 400 includes determining status or state information relating to a status or state of a household appliance. The condition or state information can be determined, for example, by the communication unit 106 of the wall hood and/or ceiling hood 100. Furthermore, the method 400 comprises manipulating 402 the lighting elements 201 of the lighting units 107 of the wall and/or ceiling hoods 100 in dependence on the condition or state information in order to project a light image 301 on the wall 110 and/or ceiling of the room in which the wall and/or ceiling hood 100 is located, which light image reproduces the condition or state information.

A user interface is thus provided, for example, on a wall and/or ceiling hood 100, which projects a light image 301 indirectly by means of the lighting unit 107 (for example by means of an RGB-LED matrix) onto the wall 110 situated behind the hood 100 or onto the ceiling of the room. Status information relating to one or more other appliances connected to the range hood 100 via a communication network (e.g., a home network) can thus be displayed in addition to the original pumping task of the range hood 100. The projected light image 301 enables the user to also detect (e.g., read) the displayed status information from a greater distance. Furthermore, light patterns and/or light information can be projected as light images 301 if necessary in order to create a harmonious and surrounding room atmosphere in the room of the wall and/or ceiling cooking hood 100.

A lighting unit 107 (for example, a RGB LED matrix) is therefore described, which is positioned at the ventilator housing of a wall and/or ceiling hood 100 in such a way that the emitted light impinges on a wall 110 or ceiling located behind the hood 100. For example, information relating to the extraction hood 110 and/or information relating to other connected household appliances can be displayed by the projected light image 301. Furthermore, ambiance-harmonious light images 301 and/or animations may also be shown, for example from natural analogies, such as arctic light.

The one or more lighting units 107 are preferably arranged on the transition region 102 of the wall and/or ceiling hood 100 in such a way that they are covered by the front end or suction region 101 of the hood 100, so that only the light projection of the one or more lighting units 107 is perceived.

The measures described in this document enable a user to detect, in particular read, precise information relating to the household appliance even from a relatively great distance. Furthermore, the one or more information-emitting lighting units 107 are provided for generating a harmonious light projection of the atmosphere, whereby an emotional appreciation for the wall and/or ceiling hood 100 can be generated. Furthermore, additional user interfaces 108 (in particular the display of the user interface 108) can be omitted if necessary by the measures described, so that the costs of the wall and/or ceiling hood 100 can be reduced. By eliminating the dedicated display of the user interface 108, an additional degree of freedom is created in the design of the front end or suction area 101 of the wall and/or ceiling hood 100. Furthermore, the required installation space can be reduced. Further, through-tool information (of one or more other tools) may be provided at the central location. For example, an alarm indication (with corresponding color and/or animation) relating to an appliance may be issued.

The invention is not limited to the embodiments shown. It is to be noted in particular that the description and the drawings shall only clarify the principle of the proposed wall and/or ceiling cooker hood.
