Description

The invention relates to a method for controlling an interior lighting of a cooking appliance and a cooking appliance.

The cooking appliances used in professional or commercial kitchens usually have interior lighting via which a cooking space can be illuminated, into which food to be cooked is introduced. The interior lighting is intended to allow the operator a good view into the cooking chamber while cooking food. The cooking appliances usually have a window in the region of the cooking chamber door, via which the operator can see the cooking space.

The object of the invention is to provide a method and a cooking appliance, with which it is possible to make the interior lighting and the operation of the cooking appliance more efficient.

The object is achieved by a method for controlling an interior lighting of a cooking appliance having a controller and a cooking chamber in which the interior lighting is provided, wherein the interior lighting of the controller in response to a state of an assembly of the cooking appliance, one of a sensor detected signal, an input made, a cooking process and / or a cooking state is controlled.

Further, the object is achieved by a cooking appliance, with a controller and an interior lighting, which is provided within a cooking chamber, wherein the controller is designed such that it detects the interior lighting in dependence on a state of an assembly of the cooking appliance, one of a sensor Signals, an input made, a cooking process and / or a state of cooking controls.

The basic idea of the invention is that the interior lighting not only serves to illuminate the cooking chamber, but is variably controlled by the controller, so that it can be used as an optical display element. The operator can therefore detect a condition and / or a change quickly and easily due to the interior lighting.

In general, the interior lighting can comprise a plurality of light sources, which are controlled individually or jointly.

A change of state of an assembly can also be the connection of a microwave source or an active accessory, which is optically displayed via the light emitted by the interior lighting.

In particular, the intensity, a signal sequence, brightness characteristics and / or the color of the light emitted by the interior lighting are changed. Due to this change in interior lighting, different states or changes can be displayed, which can be combined with each other to cover a variety of changes or conditions. Depending on the setting of the cooking appliance or a selected cooking program, different changes in the interior lighting may stand for different states, detected signals, inputs, cooking processes and / or cooking states or their changes.

As a signal sequence, for example, a flashing of the interior lighting or at least parts of the interior lighting can be considered. A particular sequence of signals may constitute a defect of the cooking appliance or one of the assemblies, which is communicated to the operator via the interior lighting. This signal sequence can accordingly correspond to an "SOS signal".

Furthermore, a signal sequence can also be a running light, provided that the interior lighting has a plurality of light sources which are assigned to an insertion level in the cooking space.

The brightness gradients are, in particular, predetermined changes in the intensity, so that, for example, the intensity of the light emitted by the interior light is reduced when a corresponding state has been reached or a corresponding change has been detected by the control.

About the variable interior lighting is usually an individualization of the cooking device possible, preferably according to customer requirements.

According to one aspect of the invention, it is provided that the controller activates the interior lighting in such a way that an operator of the cooking appliance is purposefully guided on the basis of the emitted light of the interior lighting to carry out certain activities, in particular cooking-process-related activities such as loading, cutting, pouring, stirring and / or removing of food. The interior lighting is therefore used to provide a cooking-process-specific instructions for the operator of the cooking appliance, so that it is optically guided by the interior lighting. In this case, for example, a particular color or signal sequence of the light emitted by the interior lighting can stand for a specific activity. Alternatively, certain areas of the Illuminated interior lights that indicate a specific activity.

Other activities may include cleaning programs, so that the operator is directed by the interior lighting, for example, to insert a cleaner or a rinse aid or to start a cleaning program. Again, typical signal sequences or colors can serve this purpose.

The assembly may be a fan, door and / or vent, with the interior lighting being changed according to the speed of the fan, the door closing state and / or the vent. In this way, the operator of the cooking appliance can be made aware of whether the door of the cooking chamber is closed or opened. Furthermore, the operator can quickly and easily recognize, due to the visual signal, whether the ventilation flap is functioning properly, ie whether it is closed or opened. Furthermore, by means of the interior lighting adapted to the speed of the fan wheel, it is possible for the operator to visually detect how fast the fan wheel rotates. For example, a particular color, preferably red, is for a high speed, with the interior lighting running a color gamut according to the speed. Alternatively or additionally, the interior lighting can flash according to the speed of the fan wheel, so that a short signal sequence stands for a high speed. The visual recognition of these states is possible in particular at greater distance, so that the present at the site of the cooking appliance operator can easily detect this.

According to a further aspect of the invention, the assembly is a communication interface of the cooking appliance whose status is represented by a light signal of the interior lighting. This makes it possible for the operator of the cooking appliance to visually recognize which status the communication interface currently has. This is particularly simplified because the interior lighting of the cooking appliance is also perceptible at a great distance.

In particular, the status is an established connection, for example to a cloud, a data transfer, a device connected to the communication interface and / or a WLAN status. Accordingly, the operator of the cooking appliance can detect from a great distance whether the cooking appliance carries out a data transfer such as upload or download via the communication interface. Another light signal can be sent out when the data transfer is complete, so that the operator can quickly see that the desired data is now available. The interior lighting can also indicate whether an external memory, for example a USB stick, is connected, so that this can also be detected quickly at a great distance.

Further, several kitchen appliances can optically communicate with each other, for example, two cooking appliances, both of which have such a trained interior lighting. The interior lighting then forms part of the communication interface, via which the cooking appliance communicates with another cooking appliance on the basis of the emitted light. The light signal of the other cooking appliance would then take place via the sensor of the cooking appliance, which is designed, for example, as an optical sensor.

Another aspect of the invention provides that the interior lighting acknowledges an input made by an operator with a light signal. As a result, the operator is optically signaled that his input has been recorded by the cooking appliance. If the operator makes an entry that has not been acknowledged with a light signal, he may assume that the input has not been properly received by the cooking appliance.

The input can be an operator input on a control panel or a voice input by the operator, if the cooking appliance has an acoustic sensor. Accordingly, the cooking appliance may acknowledge an instruction with a light signal verbally given by the operator. This ensures that the operator of the cooking appliance can be sure that the desired input from the cooking appliance has been detected. In addition, the operator can communicate with the cooking appliance from a distance and, in addition, receives visual feedback due to the emitted light from the interior lighting.

The voice inputs can also be commands that certain areas in the oven should be illuminated so that the interior lighting or the individual light sources of the interior lighting are verbally controlled by the operator. For example, the operator can command that a certain shelf level should be illuminated, whereupon the controller controls the interior lighting such that only this shelf level is illuminated.

A further embodiment provides that the interior lighting is controlled as a function of a setting made by the operator on a control panel, in particular the set color of the control panel. If the cooking device offers the possibility that the operator adjusts, for example, the color of the control panel in a desired color, then it can be provided that the color of the interior lighting is adapted to this color of the Control panel adjusts. This can be the same color or a complementary color, offering the operator a great variety of visual design options. Further, the operator can himself select the color of the interior lighting regardless of the color of the operation panel.

A further embodiment provides that the assembly is a core temperature sensor whose correct connection with a first light signal and / or its faulty connection with a second light signal is or will be displayed. The operator of the cooking appliance thus recognizes visually by the emitted light of the interior lighting, if the core temperature sensor is properly connected. The interior lighting thus represents a formed as a display element fuse for the correct connection of the core temperature sensor.

The interior lighting can be controlled depending on the degree of soiling of the cooking chamber. The cooking chamber is also an assembly of the cooking appliance, due to the state, ie the degree of contamination, the interior lighting is controlled. By means of the light emitted by the interior lighting, an operator of the cooking appliance can recognize from afar whether the cooking space needs to be cleaned because it is too contaminated, if a specific light signal or color is provided for this purpose. For different degrees of pollution, different colors or signal sequences can be provided, so that a graded detection of the degree of contamination is possible.

In particular, it is provided that the interior lighting is controlled by the controller with a first light signal when a cleaning of the cooking chamber should take place, and / or with a second light signal when a cleaning of the cooking chamber has to be done. Accordingly, two different degrees of contamination are defined, wherein the degree of contamination at which a cleaning of the cooking chamber has to be done, is characterized with a different light emitted from the interior lighting as a slightly soiled cooking space, which could still be used for the preparation of food.

The light signal emitted by the interior lighting can in particular vary in its brightness and / or its color in order to visually display the degree of contamination.

Furthermore, it can be provided that the interior lighting emits a specific light signal to signal the insertion of a cleaner, a rinse aid and / or the supply of the cleaner or rinse aid. The operator is prompted by these light signals from the interior lighting to a particular action during a cleaning program, namely the introduction of a cleaner or a rinse aid. In addition, the interior lighting with a specific light signal informs the operator of the cooking device about the existing supplies, so that he can quickly recognize whether the supply of detergent or rinse aid must be increased. This avoids bottlenecks.

One aspect of the invention provides that the interior lighting comprises at least one UV light source whose light is directed by the control to contaminated sites in order to make them visible. For this purpose, the interior lighting preferably has at least one UV light source, which in particular is pivotable or movable. The directional light beam from the UV light source is used to specifically point out contaminated areas, so that the operator of the cooking appliance quickly and easily recognizes where these contaminants are located. The contaminated sites may have previously been detected by a sensor.

Furthermore, the UV light source can be used to achieve an antimicrobial effect in certain areas of the oven by illuminating these areas.

According to a further aspect of the invention, the interior lighting is controlled by the controller in such a way that the interior lighting emits a light signal corresponding to the remaining cooking time. The interior lighting is accordingly used as a kind of light timer, via which the operator of the cooking appliance is shown how long the cooking process running in the cooking appliance is still running. Due to the light timer, the operator of the cooking appliance can, for example, make a decision as to whether he leaves the room in which the cooking appliance is standing, or whether he is still waiting or whether he should still start another action. This decision can be made by the operator, especially from a distance, since the light emitted by the interior lighting can be easily recognized.

Another aspect of the invention provides that the interior lighting illuminates depending on forthcoming cooking processes to be loaded levels in the cooking chamber. In this way, the operator of the cooking appliance is instructed in which area he should bring to cooking food to be cooked, since only this area is illuminated by the interior lighting. The operator of the cooking appliance is thus actively supported by the interior lighting when loading the cooking appliance.

Alternatively, only the loaded levels can be illuminated, so that the non-illuminated levels should be fed.

Furthermore, it can be provided that the interior lighting illuminates at least one subarea of the plane to be loaded, in particular a horizontal subarea. In this way, the operator can be displayed in which horizontal subarea of a plane to be loaded, he should bring a food support, which does not extend over the entire depth of the plane. In this way it can be ensured that the food support to be introduced is arranged in the region which is optimal for it within the plane, so that, for example, a good flow of air in the cooking space is made possible.

According to a further embodiment, the occupied levels are illuminated by the interior lighting. As a result, the operator of the cooking appliance can see from the outside, as the cooking progress of the food in the occupied levels is.

Another aspect of the invention provides that the controller controls the interior lighting in dependence on the loaded food. Accordingly, a different color can be provided if, for example, vegetables instead of meat in the cooking appliance or a level of the cooking chamber is introduced. This makes it possible for the operator to see from a long distance, which Gargutarten are currently in the cooking appliance. This is particularly important when a change of personnel takes place during a running cooking program, so that a new operator of the cooking appliance can directly detect the arranged in the cooking appliance food. The type of food is previously detected by a sensor provided on the cooking appliance. As an alternative or in addition, it is possible to fall back on the data stored in the control for the cooking processes and / or cooking programs taking place in the cooking appliance.

The different kinds of food can preferably be assigned a different color, for example red for meat and green for vegetables. This also increases the visual attractiveness during cooking, since the colors usually associated with the types of food to be cooked may be provided by the customers or by the operators.

According to a further embodiment, it is provided that the interior lighting is controlled by the controller when a proximity sensor detects an approach, in particular in the case of a cooking process taking place in the cooking appliance. As a result, a safety device for the operator of the cooking appliance is created because the interior lighting can emit a kind of warning signal, so that the operator of the cooking appliance is visually warned when it comes in the vicinity of the door handle, which could indicate an opening of the cooking chamber in a running cooking process , The operator is thereby protected from heat, steam and / or cleaning chemicals, which are introduced into the cooking chamber during a cleaning program.

The proximity sensor is arranged on the cooking appliance, preferably in the region of the door handle of the cooking chamber door, so that it detects a hand movement of the operator in the direction of the door handle.

According to another embodiment, it is provided that the sensor is an optical sensor which optically detects the environment, in particular the brightness, the wall color and / or the device color at the installation site of the cooking appliance, wherein the controller controls the interior lighting in dependence on the detected signal. The interior lighting can accordingly adapt to the environment, so that, for example, in a darkened room interior lighting is selected with a low intensity, as this is already sufficient under the given circumstances. In addition, the interior lighting can optically or creatively adapt to the environment, since, for example, the wall color and / or the interior color of the other devices and furniture at the site in the color choice of the interior lighting are taken into consideration. This generally results in an attractive design of the cooking appliance, which is adaptable to the selected site. Accordingly, a cooking appliance can be used at several, different sites and adapted at any time to a new site.

Furthermore, the sensor may be a motion sensor which detects the movements in the region of the installation site of the cooking appliance, wherein the interior lighting is controlled by the controller in dependence on the detected signal. Because of the movements in the area of the site, for example, it can be determined whether the site is hectic, because this leads to a typical movement, which is detected by the motion sensor and detected by the controller. In general, the mood at the place of installation can thus be determined via the motion sensor.

A further embodiment provides that the sensor is an acoustic sensor which detects the ambient noise in the region of the installation site of the cooking appliance, wherein the interior lighting is controlled by the controller in dependence on the detected signal. The interior lighting thus reacts to the ambient noise, so that the interior lighting, for example, can be used as a kind of light organ, which, among other rhythmically lit to ambient music. This embodiment is particularly important for so-called show devices in which the attention of potential customers to be achieved. In addition, the interior lighting can also adapt to the ambient noise, for example, when closed by loud ambient sounds on a large number of people who could speak for a hectic operation. Also via the acoustic sensor can thus determine the mood at the site via the motion sensor.

Furthermore, the sensor can detect a cooking accessory to be introduced into the cooking chamber and control the interior lighting corresponding to the detected cooking accessory. Depending on the introduced or provided for cooking accessories, the interior lighting can thus emit a different color or a different light signal, so that an operator of the cooking appliance recognizes from afar, which Garzubehöre are currently in the oven. This serves on the one hand to check and the quick detection by the operator.

This makes it possible in particular to achieve a coding of the Garzubehörs, so that, for example, the Garzubehör is introduced only at designated locations of the cooking chamber.

For example, so Gargutträger can be arranged only in an upper or lower portion of the cooking chamber, whereas chicken skewers or other Garzubehöre that require more space, are placed in the intended area for them. The corresponding area can then be illuminated by the interior lighting. Accordingly, the operator of the cooking appliance is instructed again by the interior lighting to carry out specific actions in the correct manner.

In particular, the interior lighting emits a light, so that a cooking accessory can be properly oriented in the cooking appliance introduced. This makes it possible, for example, that a certain corner of the cooking chamber is illuminated by the interior lighting, so that the cooking accessories is properly oriented in the cooking chamber is introduced. This is particularly advantageous if the Garzrabehör should have a proper orientation in the cooking chamber to ensure optimum cooking results. In addition, the Garzubehör may have an integrated fat drain or other properties in which a correct orientation in the oven is desirable.

Another aspect of the invention provides that the interior lighting emits a light code. Via the light code, a so-called color coding can take place, in which, for example, a cooking accessory provided for a specific cooking appliance is introduced only into the corresponding cooking appliance dispensing the light code. For example, a purple color of the interior lighting for a particular Görgarubehör be, for example, oven rack, so that in a cooking appliance with purple luminous interior lighting only this oven rack can be introduced.

Another aspect of the invention provides that spatially adjacent illumination areas are dimmed or switched off. This enhances the effect of the areas illuminated by the interior lighting, as there are no reflections of the remaining areas, which could disturb the operator of the cooking appliance. This is due in particular to the cooking chamber of the cooking appliance usually being made of a reflecting metal, for example stainless steel, which may result in many different areas of the interior lighting in that the operator can not unambiguously assign which area is currently emitting another signal. Dimming the spatially adjacent lighting areas prevents this.

Furthermore, it can be provided that a functional test of the assemblies is carried out via the interior lighting and / or a result of a functional test of the assemblies is displayed via the interior lighting. Among other things, it can be displayed to the operator whether the individual assemblies are correctly inserted, for example an air baffle is in the correct position or whether a cooking accessory is arranged inside the cooking chamber, if this should be the case. Further, an improperly hung hanger frame may be displayed via a different light signal or color than the incorrectly positioned baffle display, so that the operator or a technician can quickly identify what the problem is.

In addition, the interior lighting may indicate to the operator that the customer service or a technician should be called or that the customer service will be scheduled soon.

If necessary, the cooking device itself can instruct the customer service in the event of a fault and display this to the operator via a corresponding light signal. This has previously been determined by the cooking appliance via a function test.

In addition, the interior lighting itself may be provided to initiate a functional test by the operator or after-sales service by radiating to areas to be inspected via a spotlight that is part of the interior lighting. This results in a function test conducted by the interior lighting.

Furthermore, the interior lighting itself may be part of the functional test, for example by being used to check the tightness of seals, since the amount of transmitted light of the interior lighting indicates a degree of wear of the seal. The transmitted light is then detected by an optical sensor accordingly.

The interior lighting is preferably coupled to an adjustable mechanism, which controls the control, in particular in response to a signal detected by the sensor. For example, the sensor may be an optical sensor that detects the viewing direction of an operator of the cooking appliance, so that at least a portion of the interior lighting is specifically illuminated in the operator's line of sight to illuminate the area that the operator is looking at.

Another aspect provides that the sensor detects a door movement of the cooking appliance, in particular an opening and / or closing. Accordingly, the interior lighting is controlled at an open or just closed door of the cooking appliance, for example, to illuminate the cooking chamber targeted or large area when you open the door.

In particular, the sensor detects the viewing direction of an operator. The sensor and the controller can, for example, detect which rack level is being viewed by the operator and visually emphasize this by changing the interior lighting. This can be done by changing the color, intensity or brightness of this area. Additionally or alternatively, adjacent areas to this level can be dimmed or even switched off.

The cooking appliance may further comprise a cooking accessory, in particular a food support and / or a core temperature sensor, on which at least one light source is provided. The light source is part of the interior lighting. For example, the core temperature sensor can output different colors for the degree of cooking of a food in which the core temperature probe is inserted. Alternatively, a plurality of LEDs, in particular with different colors, may be provided on the core temperature sensor, via which the cooking progress of a cooking product assigned to it is displayed. This can be done via the color and / or the number of luminous LEDs (s).

The cooking accessory may also be a chicken skewer on which grilled chicken are skewered. The chicken skewer can have one or more LED (s) at its tip, which light up or shine in the skewered food.

In general, the cooking progress or degree of cooking can be visually displayed on the accessory using the color or the number of illuminated LEDs (s).

Another aspect provides that the cooking accessory itself has a sensor. For example, the core temperature sensor has a temperature sensor, can be determined via the data regarding the Garfortschritts and transmitted to the controller.

Another aspect provides that the interior lighting adapts its emitted light to the signal detected by the sensor of the cooking accessory or the cooking appliance. As a result, the interior lighting can be adapted to the cooking progress detected by the cooking accessory, in particular the core temperature sensor.

Furthermore, it can be provided that the interior lighting and the controller interact wirelessly. Accordingly, it is possible that the interior lighting is partially arranged on the appliance and, for example, emits light downwards, so that insertion levels provided below the appliance are illuminated in the cooking space by the cooking appliance arranged above it.

Another aspect provides that a power transmission unit is provided, which supplies the interior lighting wirelessly with energy. As a result, the light sources arranged at different locations within the cooking chamber can be supplied with energy in a simple manner. This applies in particular to light sources of interior lighting, which are arranged on a Garzrabehör.

Another aspect provides that the energy transmission unit supplies the lighting with electrical energy from the temperature and / or the air flow in a cooking chamber. This is commonly referred to as "energy harvesting", wherein the existing energies in the oven are used to provide the interior lighting of the cooking appliance with energy. This creates a particularly efficient cooking appliance.

Further advantages and features of the invention will become apparent from the following description and the drawings, to which reference is made. In the drawings show:

1 schematically an inventive cooking appliance in a closed position, and

2 the cooking appliance off 1 in an open position.

In 1 is a cooking appliance 10 shown in a closed position.

The cooking appliance 10 has a housing 12 on, on which a cooking chamber door 14 is pivotally arranged to a cooking chamber 16 to close off the housing 12 is surrounded.

The control 28 This is among other things with the control panel 22 connected to the control panel 22 made inputs from the controller 28 can be processed.

When the oven door 14 is open, like this in 2 is shown, you can also in the entire oven 16 and not just in the window 18 shared area. For example, the cooking chamber walls are now visible. This is typically in the closed state of the cooking appliance 10 not the case, because the window 18 at least slightly smaller than the whole of the oven door 14 closable opening of the cooking chamber 16 ,

The following is on the 2 received. From the 2 it turns out that the cooking appliance 10 an interior lighting 30 which has several individual light sources 32 of which only a few in 1 are shown for the sake of clarity.

The individual light sources 32 can each be assigned to a rack level E, of which four are shown in the illustrated embodiment, ie insertion levels E1 to E4.

The shelf levels E1 to E4 are typically via slide-in bars 34 defined, each on opposite cooking chamber walls of the cooking chamber 16 are arranged. In the slip-ins 34 can be a cooking accessory 37 are inserted, as shown by way of example in the plane E2 based on a food support.

The cooking accessory 37 also has light sources in the embodiment shown 32 on top, below the cooking accessory 37 are arranged so that they can illuminate underlying insertion levels E1 to E4, provided that they comply with the control 28 be controlled.

Alternatively, the Garzrabehör 37 also be a chicken skewer, which can extend in particular over several insertion levels E1 to E4, as he usually upright in the cooking appliance 10 is arranged.

In addition, the cooking device points 10 sensors 36 on, in different places of the cooking appliance 10 can be arranged as well as have a different function. For example, it may be at the sensors 36 around a proximity sensor 38 , an optical sensor 40 , an acoustic sensor 42 , a motion sensor 44 and / or a sensor 46 to detect food to be cooked, on the one in the oven 16 introduced food can be determined.

The proximity sensor 38 can preferably also on the cooking chamber door 14 be provided (see 1 ), bringing him closer to the door handle 20 detected, as will be explained below.

Furthermore, goes from the 1 forth that the cooking appliance 10 a fan 48 may have, from which the fan 50 is shown schematically. The fan wheel 50 Can be provided behind a baffle, what in 2 not shown for the sake of clarity. Because of this, the fan is 50 only shown by dashed lines.

The fan 48 as well as the fan wheel 50 can also be arranged on a side wall of the cooking chamber.

In general, the positions shown of the individual elements of the cooking appliance are merely exemplary, in particular due to the better representability. Accordingly, the individual elements can also be provided at other positions.

Furthermore, the cooking appliance 10 usually a ventilation flap 52 on which it is possible to moisture or steam from the oven 16 drain.

In addition, the cooking device points 10 a communication interface 54 on, over which the cooking appliance 10 for example, with the Internet, another cooking appliance 10 or generally connectable to another external device. This can in particular be a wireless communication interface, for example Bluetooth, WLAN, radio or similar interfaces for wireless data transmission standards.

Additionally or alternatively, the communication interface 54 have a sub-interface for an external device, such as a data memory.

In the embodiment shown, moreover, there is a power transmission unit 56 shown over which the individual light sources 32 the interior lighting 30 be energized. The energy transfer can be done wirelessly, so on a complex wiring of the cooking appliance 10 can be waived.

Not only the energy transfer of the interior lighting 30 , but also their control via the controller 28 can be wireless.

Alternatively or additionally, the energy transmission unit 56 designed such that the interior lighting 30 or the individual light sources 32 be supplied with electrical energy from the temperature and / or the air flow in the cooking chamber 16 is won. Accordingly, the power transmission unit 56 to use energy harvesting.

The cooking appliance 10 also includes a connection 58 for a core temperature probe 60 , about which the core temperature of one in the cooking chamber 16 introduced Garguts can be measured. This is the core temperature probe 60 typically plugged into the food and it transmits the measured data via the connection 58 to the controller 28 , The core temperature probe 60 therefore has a sensor 36 on, which is designed as a temperature sensor.

In the embodiment shown, the core temperature sensor is 60 with the connection 58 over a cable 62 connected. Alternatively, however, it may also be provided that the transmission of the data from the core temperature probe 60 wirelessly, for example via Bluetooth, WLAN, wireless or other wireless data transmission standards.

The core temperature probe 60 In addition, in the embodiment shown, comprises a plurality of light sources 32 that are part of the interior lighting 30 are. At the light sources 32 they can be LEDs, also from the controller 28 can be controlled.

The cooking appliance 10 thus has a variety of different modules, each with the controller 28 communicate with or with the controller 28 communicate. This includes in particular the interior lighting 30 as well as the individual light sources 32 the interior lighting 30 that about the controller 28 to be controlled.

Accordingly, it is envisaged that the controller 28 the interior lighting 30 , in particular the individual light sources 32 the interior lighting 30 , depending on a state of an assembly of the cooking appliance, one of one of the sensors 36 detected signal, an input made, in particular on the control panel 22 , a cooking process and / or a cooking state is driving.

The cooking state of one in the oven 16 Garguts are usually transported via one of the sensors 36 detected during the cooking process, for example via the core temperature probe 60 provided sensor 36 , In addition, the controller includes 28 a Garprozessspeicher in which are stored for the cooking process relevant data, so the controller 28 due to the deposited data the interior lighting 30 can drive.

This can be provided in particular that the interior lighting 30 is changed, in particular with regard to the intensity, a given signal sequence, brightness gradients and / or the color of the interior lighting 30 emitted light.

There may be individual light sources 32 or all light sources 32 the interior lighting 30 be switched simultaneously or alternately. This depends in particular on what signal about the interior lighting 30 to be sent out.

In the case of the interior lighting 30 emitted light signals may be chases running along the corresponding insertion levels E1 to E4. In this case, in particular, a rack level E1 to E4 are illuminated when the food to be cooked from the sensor 46 has been recognized.

In addition, it can be provided that at least one light source 32 an adjustable mechanism 64 over which the light source 32 is adjusted. This light source 32 can be done accordingly from the adjustable or pivotable mechanism 64 be adjusted so that certain areas of the food are selectively and selectively illuminated.

Alternatively or additionally, it can be contaminated 66 in the oven 16 be pointed by light rays from the light source 32 targeted on pollution 66 be adjusted or directed. In particular, the light source used for this purpose 32 which is used to indicate contamination 66 serves, a UV light source 68 be so under normal light invisible contamination 66 for the operator of the cooking appliance 10 be visualized by the UV light.

The UV light source 68 or that of the UV light source 68 emitted light can be used to act antimicrobial, so that microbial contamination in the oven 16 be prevented.

The UV light source 68 can also be an adjustable mechanism 70 or movably arranged so that it can output a guided light beam.

In addition, one of the sensors 36 the viewing direction of an operator of the cooking appliance 10 capture if this through the window 18 of the cooking appliance 10 looks to one of the light sources 32 about the adjustable mechanism 64 align so that the area inspected by the operator within the cooking chamber 16 illuminated additionally or differently. For example, the adjacent areas may be dimmed or turned off so that the area viewed by the operator visually emerges.

The from the sensor 36 Information collected for this purpose is sent to the controller 28 sent the light source 32 controls accordingly, in particular the adjustable mechanism 64 that the light source 32 assigned.
