driven, for example, by means of a motor. However, the framework of the invention also comprises that the adjustment device is an electronic device, for example, a circuit for adjusting the light intensity of the light source. Preferably, in an illumination device with several light sources, an adjustment device is associated with each light source, that is, it is possible to modify the light emission of this light source.

The term "communication unit" of the lighting device includes the concept of a unit that is at least designed to receive information, which can also be called informational data. Preferably, the communication unit constitutes a unit that is connected to the less another communication unit, specifically, with a communication unit of a kitchen, at least temporarily to receive information.

The reception of the information can take place through a cable connection between the communication units. However, reception preferably takes place through a wireless connection between the communication units. The communication unit of the lighting device may be a separate unit that is connected to the control unit of the lighting device, or the communication unit is integrated in the control unit.

According to the invention, the kitchen device kitchen also has a communication unit. The communication unit may be part of a kitchen control unit, or constitute a separate unit with respect to the kitchen control unit, which is connected to the control unit at least to receive information from it.

According to the invention, information relating to the state of the kitchen at least to the lighting device is transmitted via the kitchen communication unit. The term "information relating to the state" includes the concept of information that indicates the status of at least one part of the kitchen. The part of the kitchen whose status is indicated may be, for example, the cooking range of the kitchen. status of the cooking field can indicate here, for example, the operating status, for example, on / off, preferably the part of the kitchen whose information regarding the status is transmitted to the lighting device constitutes only one area of the field of cooking, in particular, a cooking zone. The term "cooking zone" includes the concept of a spatially delimited heated cooking area. Also in this form of realization, the state of the area, that is, of the cooking zone, can be, for example, its operating state, that is,

5

30

activated, in particular, "on", the degree of power set, or "off". However, alternatively or additionally, in this form of realization, the state may also indicate, for example, the temperature or at least that a temperature has been exceeded in a part of the kitchen, in particular, in a cooking zone .

Alternatively to the spatially delimited cooking zones, that is, fixed, the area of the cooking field whose information regarding its status can be transmitted to the lighting device can also be called the cooking field area in which it can be heated when in contact with a cooking vessel. In this case, the state of the cooking field area may be, for example, the presence of a cooking vessel in the area. Additionally, heating of the cooking field in the area of a recognized cooking vessel can also be used as information relating to the state.

In addition to the indication of the state of the part or area of the kitchen, the information relating to the state preferably also includes an indication relative to the position of the area. As an example, when a right front cooking zone of a cooking field is turned on, the status information can say "right front cooking zone on".

According to the invention, the control unit of the lighting device serves at least to activate an adjustment device. The expression "activate an adjustment device" includes the concept of, for example, the movement of at least a part of the adjustment device or the activation or deactivation of at least a part of the adjustment device, for example, the power supply To the light source.

Through the activation of the lighting device adjustment device, the light emission of the lighting device is modified. According to the invention, the modification of the light emission is made based on information related to the state that has been received from the kitchen. As described above, this information relating to the state is preferably information relating to the state of a part, in particular, of an area of the kitchen.

By taking place according to the invention a communication of the information relating to the state between the kitchen and the lighting device of the kitchen device, and also presenting the lighting device an adjustment device to modify the emission of light and when this is activated adjustment device by a control unit connected to a communication unit of the lighting device, multiple advantages can be achieved. In particular, the emission of light can be adapted so

5

25

30

Specify the state of the kitchen. This adaptation can take place automatically, so that it is not necessary for the user to interact, which simplifies the operation. In addition, by providing at least one adjustment device, a flexible adaptation of the light emission is possible.

According to a preferred embodiment, the cooking device comprises a fume hood, and the at least one lighting device is partially or completely integrated in the fume hood. The expression "partially or completely integrated in the fume hood" includes the concept of a provision in which at least the light source (s) of the lighting device are arranged in or next to the fume hood In a preferred manner, the adjustment device is also arranged in or next to the fume hood The other parts of the lighting device, in particular, the control unit and the communication unit, can also be integrated so preferred in the fume hood.

Particularly preferably, the lighting device is integrated in the fume hood so that it can emit light down at least temporarily. Since the fume hood is usually installed on top of a kitchen, at least part of the kitchen can therefore be illuminated at least temporarily. An advantage of the integration of the lighting device in the fume hood is that the fume hood already has a control unit and, where appropriate, also a communication unit. These units of the fume hood can be used for the lighting device when this is integrated in the fume hood. In this way, the structure of the kitchen device is simplified altogether.

According to the invention, the adjustment device may constitute a device for modifying the intensity of the light that is emitted by the lighting device. In this embodiment, the adjustment device may therefore constitute, for example, a circuit by which the power supply to one or more light sources can be modified, that is, intensified or reduced. An advantage that can be achieved with the modification of the intensity of the light is, for example, that the fact that a cooking zone still has residual heat can be indicated by lighting the cooking zone with a light intensity different from that desired for cooking , and that the user can be warned.

According to another form of realization, the adjustment device is a device for modifying the color of the light. In this case, it is possible, for example, to activate or deactivate, that is, turn on or off, light sources with different colors. However, the framework of the invention also comprises that, to modify the color, the adjustment device places tinted panels, tinted windows, or other tinted optical elements in front of the light source.

According to another form of realization, the adjustment device is a device for modifying the orientation of the light. The term "orientation" includes the concept of the direction of radiation in which the light is emitted by the lighting device. Through the modification of the orientation of the light, it is possible that the lighting device optionally illuminates different areas of the kitchen. As an example, a particular cooking zone can be illuminated and, by activating the setting device, another cooking zone can then be illuminated by the same light source. Therefore, the structure of the lighting device is simplified, since the amount of light sources does not have to match the amount of cooking zones in the kitchen. In addition, you can also freely choose the position of the area to be illuminated. By merely providing a source of light for each given cooking zone, the areas between the cooking zones or other areas of the cooking field cannot be illuminated.

According to a form of realization, the adjustment device comprises a mobile element. The term "mobile element" includes the concept of an element of one or more pieces, which can be moved with respect to a light source of the lighting device. Since the position of at least a part of the adjustment device can be modified relative to the light source, the emission of light from the lighting device can be easily modified. As an example, in a mobile element that serves as an adjustment device, one or more light output openings can be provided that modify its relative position with respect to the light source when the adjustment device moves with respect to the source of light and, thus, modify the emission of light.

According to one embodiment, the adjustment device comprises a panel of opaque material, which has at least one opening for the passage of light. In this embodiment, the focus of the light emitted by the light source can be performed, on the one hand, on the opening for the passage of light and, on the other hand, the area covered by the opaque material is not illuminated around the opening for the passage of light and, in this way, a certain area can be illuminated concretely, by

5

35

example, a cooking zone. An adjustment device that constitutes a panel is preferably provided near the light source at least temporarily. By way of example, the adjustment device can be temporarily arranged below the light source, that is, it can be moved there.

The movement of the adjusting device with respect to the light source may be a movement towards the light source or away from the light source. However, alternatively or additionally, the adjustment device may also be slidable or pivoting with respect to the light source.

In the simplest case, the adjustment device may constitute a flat panel in which one or more openings for the passage of light are provided. A panel of this type, which is arranged below the light source, can be displaced, for example, in the plane of the panel. In this way, the position of the light emission through the opening for the passage of light can be modified.

However, according to a preferred embodiment, at least a part of the adjustment device is pivotally disposed with respect to the light source. This means that, by way of example, a panel of the adjustment device can be moved or rotated around the axis. The axis of rotation preferably runs through the light source. In this way, the part of the adjustment device formed by the panel can be taken, for example, from a position in which it is located below the light source to a position in which the panel is above The light source. In the last position of the panel, the kitchen can be illuminated using all the light emitted by the light source. In addition, the embodiment in which at least a part of the adjustment device is pivotally arranged has the advantage that the need for space in the width and depth of the lighting device with respect to a device is reduced adjustment that is slidably arranged. In lighting devices that are integrated in a fume hood and, in particular, in the vision hood of the fume hood, the width and depth of the lighting device must be kept reduced in order to use the largest area possible from the underside of the vision cover to suck the mist and steam. Another advantage of pivoting is that the panel is no longer directly exposed to impurities in the position in which it is located above the light source.

According to one embodiment, the adjustment device has a bowl shape. The term "bowl" includes the concept of a rotationally symmetrical channel or shape

5

35

that constitutes, for example, a hollow spherical segment, in particular, a hollow hemisphere. However, geometries that differ from a rounded geometry can also be used. However, in each case the bowl has an open shape towards one side, specifically upwards. The light source may at least partially penetrate this open shape of the bowl or lie on the open side. Particularly preferably, in a rotating bowl shape, the axis of rotation lies in a plane that runs through the light source. In this way, the bowl shape can be pivoted about 360 ° around this axis.

According to a preferred embodiment, the kitchen is an induction cooker with at least one detection unit for the position of at least one cooking vessel. A sensor unit can be used as a detection unit. The detection unit is preferably provided in an embodiment of the kitchen in which the cooking field is composed of a continuous heating surface that is composed of several adjacent heating units. The detection unit may be formed in an induction module, for example, by one or more signaling turns that are incorporated in the coil coil of the heating units that serve to generate an alternating magnetic field. In this way, by modifying or weakening the alternating magnetic field, it can be recognized if there is a cooking vessel on the cooking field. Then, depending on the position of the cooking vessel, the heating element (s) under the cooking vessel can be activated.

With this, when a cooking vessel is supported on the kitchen and, specifically, on the cooking field, it can be recognized through the detection unit that there is a cooking vessel on the cooking field, as well as determining its position . Preferably, the detection unit extends throughout the cooking field. Thus, unlike in cooking fields with predetermined cooking zones, a cooking zone can be generated simply by resting a cooking vessel on it. If the cooking vessel is moved over the cooking field, then the modification of the position is recognized. This modification of the status of the kitchen can be transmitted through the communication unit of the kitchen to the communication unit of the lighting device and, thus, the adjustment device of the lighting device can be activated correspondingly to the new position of the cooking vessel. In this way, also if the cooking vessel is moved over a cooking field, it

5

30

always ensure that the area in which the cooking vessel is located is illuminated.

According to another aspect of the invention, the invention refers to a method for putting into operation a lighting device of a kitchen device, which comprises at least one lighting device and a kitchen. The procedure is characterized by the fact that a detection unit detects the status of at least a part of the kitchen, when a predetermined state is recognized, information relating to the state is transmitted to the lighting device and, based on the information relating to the state , at least one lighting device adjustment device is activated to illuminate at least the part of the kitchen whose state has been transmitted.

The predetermined state of the kitchen, in which the information relating to the state is transmitted to the lighting device, is preferably an operating state of at least a part of the kitchen, in particular, of at least one area of the cooking field of the kitchen. The default state can be, for example, a threshold value or other predetermined criterion. As a threshold value, for example, the maximum temperature of an area of the cooking field can be stored until the status information is transmitted to the lighting device. Alternatively or additionally, the criteria may be, for example, the presence of a cooking vessel in a cooking zone. Finally, as criteria it may also be stored that the information related to the state is transmitted to the lighting device when at least one state of the kitchen is modified. The status of at least part of the kitchen is detected by the kitchen detection unit. The check on whether the detected state corresponds to a predetermined state can also be carried out in the detection unit. However, alternatively or additionally, the check can also be carried out in a kitchen control unit.

In the process according to the invention, when the information relating to the state transmitted to the lighting device is used to activate at least the lighting device adjustment device to illuminate at least the part of the kitchen whose state has been transmitted, the light emission It can be adapted for at least this part of the kitchen to the current state of the kitchen.

According to other forms of realization, the information related to the state consists in the presence of a cooking vessel on a part of the kitchen, an indication

5

10

fifteen

twenty

25

30

35

referring to the temperature of a part of the kitchen, an indication referring to the activation of a part of the kitchen and / or cooking instructions.

If the presence of a cooking vessel on a part of the kitchen is used as state-related information, then it can be ensured that the cooking vessel is illuminated. In addition, the handling of the kitchen device is facilitated, since the lighting of the area in which the cooking vessel is located is carried out automatically. The expression "part of the kitchen" includes the concept of a cooking field or an area of the cooking field, specifically, of a cooking area of the cooking field.

In an alternative embodiment, also the absence of a cooking vessel on a part of the kitchen, in particular, of the cooking field, can be used as information relating to the state. In this embodiment, the temperature of the part of the kitchen, in particular, of cooking zones of the cooking field, as other information relating to the state, is additionally monitored. If there is no cooking vessel above the cooking zone, but the temperature is above a threshold value, then the cooking zone can be illuminated by the lighting device to warn the user.

However, the temperature of a part of the kitchen, in particular, of a cooking zone, can also be used as information relating to the state regardless of whether the presence of a cooking vessel is monitored. This embodiment is advantageous, since, having a cooking vessel placed on a cooking zone, the heating of the cooking zone is no longer visible to the user by means of incandescent heating elements, whereby You can warn the user about the residual heat of the cooking zone by means of the lighting device.

Likewise, as an information relating to the state, an indication concerning the activation of a part of the kitchen can be used as an example. The indication concerning the activation may concern, for example, the entire cooking range of a kitchen or one or more cooking zones. The indication relating to activation can also be called operating status, and can express, for example, "on", "off", or indicate the degree that is set. If, by way of example, the adjustment of the so-called degree of potentiation is recognized for a cooking zone, then the lighting device adjustment device can then be adjusted so that this zone is illuminated with great intensity.

30

According to another form of realization, cooking information can also be used as status information. Cooking instructions can be stored, for example, as automatic recipes in the kitchen, specifically, in a control unit. In this embodiment, by modifying the intensity or color of the light, the user of the cooking device can be told, for example, that the cooking product is still boiling in a cooking phase. As an alternative, the automatic recipe can also be stored, for example, in a fume hood in which the lighting device is integrated. In this case, the modification of the light emission can serve as a requirement addressed to the user to adjust the part of the kitchen to another degree, specifically, a cooking zone.

If the presence of a cooking vessel is recognized on a part of the kitchen, in particular on a cooking zone, then the adjustment device is preferably adjusted so that the light is oriented by the lighting device accordingly to the position of the cooking vessel. In this form of realization, in addition to the direction, the intensity of the light and / or the color can also be modified.

By recognizing that a predetermined temperature of a part of the kitchen, in particular of a cooking zone, has been exceeded, the adjustment device can be adjusted such that the light is oriented by the lighting device in a manner corresponding to the position of this part of the kitchen, in particular, of the cooking zone and that, in addition, the intensity and / or color of the light be modified as appropriate. In this form of realization, the information relating to the state may be a maximum temperature called residual heat. In this way, it is possible to warn the user of the kitchen device by modifying the light emission of the lighting device.

According to another form of realization, when the shutdown of the kitchen is recognized, the activation of several parts of the kitchen and / or when the presence of several cooking vessels is recognized on the kitchen, the adjustment device is adjusted in such a way that it illuminates The entire kitchen surface. If the adjustment device constitutes a mechanical element that is a panel, for example, a bowl-shaped panel with an opening for the passage of light, then by recognizing one or more of these states, the panel can be pivoted upwards around the light source and, therefore, completely unlock the light emission of the light source down.

When the entire surface of the kitchen, which is the cooking field, is illuminated, when the kitchen is turned off, there is no longer an illumination of only one cooking point of an earlier confusing cooking process for the user of the kitchen device.

Also if several parts of the kitchen are activated, in particular several cooking zones, it may be advantageous to illuminate the entire cooking field. In a kitchen with an induction cooking range, the recognition of the presence of several cooking vessels on the kitchen can also cause the adjustment device to be adjusted so that the entire kitchen surface is illuminated.

The advantages and characteristics described with respect to the kitchen device according to the invention prevail (insofar as they are applicable) in a corresponding manner for the process according to the invention and vice versa and, therefore, are only described once given the case.

In figure 7, another embodiment of the cooking device 1 according to the invention is shown. In this embodiment, the kitchen 11 can optionally have a Ceran field or an induction cooking field, where in the induction cooking field the cooking zones are predetermined in a fixed way or are set correspondingly to the position of a cooking vessel; that is, the embodiment can correspond to the first or the second embodiment of the kitchen device 1. If it is recognized that none of the cooking zones is activated, or that there is no cooking vessel on the field of firing 110, this information relating to the state can be transmitted to the lighting device 100. This can then orient the adjusting device 102 such that all the light emitted by the light source 101 is emitted downward and, thereby, the entire cooking field 110 is illuminated.

This orientation of the adjustment device 102, shown schematically in Figure 8, can also be manually adjusted by the user. In addition, this orientation may be the standard orientation of the adjustment device 102. Finally, it is also possible that the orientation of the adjustment device 102 shown in Figure 8 may be adjusted if it is recognized that over all cooking zones 114 of a field of cooking 110 cooking vessels 2 are placed or that all cooking zones 114 are activated.

In Fig. 9, an embodiment of a lighting device 100 is shown schematically. Here, the lighting device 100, of which only light emitting unit 1000 is observed, is an elongated unit. In this embodiment, the light emitting unit 1000 comprises a housing 1001, in which two light sources 101 are provided. To each light source 101 an adjustment device 102 is associated, that is, it is arranged in such a way. that the light emitted by the light source 101 can be emitted in a directed manner.

In figure 11, a schematic bottom view of a fume hood 10 of an embodiment of the cooking device 1 is shown. Here, the lighting device 100 is arranged in the front area of the fume hood 10. two light sources 101 with the corresponding adjustment devices 102 are arranged in the left and right area of the fume hood 10. In the embodiment shown, the light sources 101 are arranged in a housing 1001. However, the framework of the invention

It also comprises that the light sources 101 with the associated adjustment device 102 be incorporated directly into the lower side of the fume hood 10.

The present invention is not limited to the forms of realization represented. It is possible that only one light source is provided in the lighting device. If the lighting device is provided next to a fume hood, the light source is preferably located here in the center of the bottom side of the fume hood. The light source may be arranged, for example, in the center of the rear area of the lower side of the fume hood. As an alternative, it is also possible that more than two light sources are provided. By way of example, two light sources may be provided in the rear area of the lower side of a fume hood, and two light sources in the front area of the lower side of a fume hood.

Likewise, it is also possible for the adjustment device to present an embodiment that differs from the bowl-shaped panel shown with an opening for the passage of light. By way of example, the adjustment device may have mirrors and / or lenses through which the light emitted by the light source can be directed in one direction.

The adjustment device can be driven by motor, in particular, by electric motor.

The present invention can be integrated, for example, in so-called smart homes. In these concepts, the interaction between domestic appliances is increasing more and more. In the present invention, a kitchen and a fume hood with a lighting device preferably share a common communication bridge. The communication can be carried out, for example, by means of a wireless connection. The kitchen communicates here information regarding the position of the cooking vessels, the power supply, and other variables of their status to the fume hood, in particular, to the lighting device. With this information, the control unit, which can also be called a control module, can improve the lighting configuration of the fume hood, in order to improve the cooking experience for the user in accordance with standards default

With the present invention, it is possible to implement multiple features that improve the interaction between the fume hood and the kitchen.

According to one form of realization, only the area currently used is illuminated, where the lighting can occur, for example, following the movement of the cooking vessels. In this way, it is possible to improve certain technologies, for example, the power move or the induction fields with scrollable cooking zones.

According to another form of realization, in the lighting, for example, the color, the intensity, or the light sources are modified, which are also called lighting means or fuses, correspondingly to different kitchen settings. selection of settings. Here, it is possible, for example, to selectively illuminate an activated cooking zone. It is also possible to indicate a potentiation activation or a modification of the power supply that is necessary for the automatic execution of a recipe.

In a form of realization, in the fume hood, the adjustment device, which can also be called a mobile part, can be coupled with mirrors and / or lenses with the light source in order to be able to deflect or move the area of lighting to the desired position, where there is an active mode. In a given position, the adjusting device can be brought to a position such that the normal, entire area of the kitchen, that is, the cooking field, can be illuminated again under the fume hood.

The present invention brings multiple advantages. The kitchen device, which can also be called a system, can improve the applicability of complex functions related to the movement of cooking vessels. The system can be customized in accordance with the brand or the user, for example, by setting the information regarding the default state.

When using an adjustment device that constitutes a mobile part, in particular a bowl-shaped panel, the form of realization is less complex than when using projectors and the like. In addition, the fume hood can be operated here simply in a normal standard.

Unlike in the state of the art of lighting systems, the present invention comprises the movement of the cooking product, in particular, of the cooking vessels, and all lighting modifications are adjusted taking into account the settings of the kitchen and / or predetermined cooking characteristics.
