The invention relates to a cooking system and a method for operating a cooking system.
A cooking system having an operator interface and a control unit is already known from the prior art. The control unit provides multiple cooking functions, from which an operator can select freely by means of an operating input by way of the operator interface, without having to input an identification characteristic and independently of a placement unit placed on a cooking surface.
It is the object of the invention in particular to provide a generic system with improved properties in respect of ease of operation.

In particular the cooking system has at least one placement plate. The placement plate is provided in particular for the vertical and/or horizontal placement of at least one placement unit and/or the horizontal placement of at least one item to be cooked. A “placement plate” refers in particular to at least one plate-type unit which is provided for the vertical placement of at least one placement unit and/or the horizontal placement of at least one placement unit and/or the vertical placement of at least one cookware item and/or the horizontal placement of at least one item to be cooked for the purpose of a heating operation.

In particular the cooking surface is configured as a partial surface region of the placement plate, below which at least one heating unit is arranged in an installed position. In particular the cooking system comprises the heating unit, which is configured in particular as an induction heating unit.
The expression that the control unit releases and/or blocks at least one cooking function for the placement unit as a function of at least one identification characteristic “for at least one placement unit” means in particular that the control unit releases and/or blocks the cooking function for in particular just one placement unit and/or for at least two, in particular at least three, advantageously at least four, particularly advantageously at least five, preferably at least six and particularly preferably all the placement units, which are in particular placed on the cooking surface, as a function of the identification characteristic.

Alternatively or additionally at least one cooking function could be in particular a type of boiling and/or a type of cooking and/or a type of heating operation.
The expression that the control unit releases and/or blocks at least one action “as a function of at least one characteristic” means in particular that the control unit compares the characteristic with at least one reference characteristic for the characteristic, which can be stored and/or is stored in particular in the storage unit of the control unit, and releases the action in particular if the characteristic corresponds at least largely and advantageously completely to the reference characteristic for the characteristic and blocks the action in particular if the characteristic differs in at least one feature and/or in at least one property from the reference characteristic for the characteristic.

The control unit in particular compares the input identification characteristic with at least one reference characteristic for the identification characteristic. In particular the control unit has at least one storage unit, in which at least one reference characteristic for the identification characteristic can be stored and/or is stored. At least one reference characteristic for the identification characteristic could be stored, for example predefined, in the storage unit. Alternatively or additionally at least one reference characteristic for the identification characteristic could be stored in particular manually in the storage unit. The control unit could be provided in particular to receive at least one reference characteristic for the identification characteristic, in particular from at least one further unit, for the purpose of storing the received reference characteristic for the identification characteristic in the storage unit.
The control unit releases the cooking function in particular if the input identification characteristic corresponds at least largely and advantageously completely to at least one reference variable for the identification characteristic.

The cooking system in particular has at least one output unit, which is provided in particular to output at least one operating parameter. The output unit could be configured separately from the operator interface for example. The output unit is advantageously configured at least partially as a single piece with the operator interface and is in particular integrated at least partially in the operator interface. In particular the control unit controls and/or regulates the output unit in at least one operating state.
“Provided” in particular means specifically programmed, designed and/or equipped. That an object is provided for a specific function means in particular that the object complies with and/or performs said specific function in at least one application and/or operating state.
It is also proposed that the cooking system has at least one detection unit, which is provided to detect at least one placement unit characteristic of the placement unit, as a function of which the control unit releases and/or blocks a heating operation for the placement unit. A “detection unit” refers in particular to a unit which is provided to detect and/or receive the placement unit characteristic. In particular the detection unit could have at least one sensor unit, which could be provided to detect the placement unit characteristic. A “sensor unit” refers in particular to a unit which has at least one detector for detecting at least one sensor characteristic and which is provided in particular to output at least one value characterizing the sensor characteristic, the sensor characteristic advantageously being a physical and/or chemical variable. The sensor unit could be provided for example to detect the placement unit characteristic inductively and/or capacitively. Alternatively or additionally the sensor unit could be provided for example to detect the placement unit characteristic by means of at least one camera and/or by means of electromagnetic radiation and/or by means of inductive coupling and/or by means of capacitive coupling and/or by means of an electric current and/or by means of an electric voltage. In particular the sensor characteristic characterizes the placement unit characteristic. The control unit determines at least one placement unit characteristic as a function of the sensor characteristic in particular in at least one operating state. In particular the detection unit could have at least one receive unit, which could be provided to receive the placement unit characteristic. In particular the receive unit could be provided to receive the placement unit characteristic from the operator interface and/or at least one further unit and/or at least one mobile device and/or at least one network. The further unit is in particular an external unit, which is configured and/or arranged in particular differently from the placement unit. In particular the further unit could be integrated in at least one cooktop and/or in at least one mobile device. Alternatively or additionally the further unit could be part of a network. The mobile device could be for example a cellphone and/or a tablet and/or a laptop and/or a mobile phone. The network could be for example a household network and/or a global network and/or a regional network and/or a network within a building. A “placement unit characteristic” of a placement unit refers in particular to a characteristic which characterizes the placement unit and/or which is assigned to the placement unit. In particular the placement unit characteristic differs from a characteristic which is in particular a function of at least one operating state and/or at least one placement position. The placement unit characteristic differs in particular from a temperature and/or a cooking state and/or a placement position and/or a number of heating units heating the placement unit and/or a heating zone. For example, at least one placement unit characteristic could be a geometric characteristic. The geometric characteristic could be for example a shape and/or a configuration and/or a height and/or a diameter and/or a weight. Alternatively or additionally at least one placement unit characteristic could be a suitability characteristic. The suitability characteristic could be for example a material, in particular of a surface of the placement unit to be heated and/or a type and/or a color, in particular of a surface of the placement unit to be heated. A suitability characteristic which is a type could be for example a pot and/or a pan and/or a steam cooking appliance and/or a wok and/or a teppanyaki plate and/or a toaster and/or a grill. This in particular allows a high level of safety to be achieved as a specific placement unit in particular can only be heated in the event of a specific and/or appropriate and/or suitable placement unit characteristic.
It is also proposed that the control unit has at least one storage unit, in which at least one reference characteristic for the placement unit characteristic is stored in at least one operating state and at least one identity is assigned to the placement unit by comparing the reference characteristic with the detected placement unit characteristic. At least one reference characteristic could be stored, for example predefined, in the storage unit. Alternatively or additionally at least one reference characteristic could be able to be stored in particular manually in the storage unit, in particular in at least one further operating state, which is before and/or precedes the operating state in particular in time. In at least one operating state the control unit in particular compares the reference characteristic with the detected placement unit characteristic of the placement unit. If the detected placement unit characteristic of the placement unit corresponds to at least one reference characteristic for the placement unit characteristic, the control unit assigns an identity to the placement unit and/or identifies the placement unit. A “reference characteristic” refers in particular to a characteristic which defines and/or forms a reference object, by means of which at least one identity can be assigned to a placed placement unit. The identity could be known and/or unknown for example. Alternatively or additionally the identity could have at least one placement unit characteristic, for example a geometric characteristic and/or a suitability characteristic. This in particular allows identification of the placement unit, in particular allowing a tailored and/or optimal heating operation for the placement unit.
At least one cooking function could in particular be a sensor function, with which the control unit detects at least one sensor characteristic, in particular by means of at least one temperature sensor and/or at least one acceleration sensor and/or at least one motion sensor and/or at least one weight sensor and/or at least one sensor for detecting at least one electrical characteristic and heats the placement unit in particular as a function of the sensor characteristic. At least one cooking function is preferably a safe operating state, in which the control unit releases a heating operation for at least one known placement unit and blocks a heating operation for at least one unknown placement unit. In particular the control unit considers and/or identifies a placement unit, to which at least one identity can be assigned, as a known placement unit. A known placement unit in particular has at least one known placement unit characteristic and advantageously at least two, particularly advantageously at least four, preferably at least eight and particularly preferably only known placement unit characteristics. The control unit considers and/or identifies a placement unit, for which identity assignment fails and/or is not possible, as an unknown placement unit. An unknown placement unit in particular has at least one unknown placement unit characteristic and could in particular have at least one further unknown placement unit characteristic. A “safe operating state” refers in particular to an operating state in which the control unit blocks at least one heating operation and/or at least one cooking function that is different from an operating state in particular for at least one placement unit. This in particular allows a high level of safety to be achieved and/or an optimal cooking result, in particular for a known placement unit, as the known placement unit can in particular be heated optimally. By blocking a heating operation for unknown placement units and in particular only heating known placement units, it is possible in particular to reduce the risk of boiling over and/or overheating.
For example, at least one cooking function that is a normal operating state could be preset and inputting of the identification characteristic could be necessary in particular to release the cooking function that is a safe operating state. The safe cooking mode, in particular the cooking function that is a safe operating state, is preferably preset. A “preset” function refers in particular to a function that has been programmed and/or set in the factory and is provided in particular for preferred execution and is automatically activated and/or selected and/or called up and/or executed in particular at start-up, in particular of a cooktop. This results in particular in a high level of safety for an operator and/or specific suitability for elderly and/or forgetful people, for whom in particular there might be a high risk of forgetting the placement unit on the cooking surface and/or forgetting the identification characteristic.
It is also proposed that at least one cooking function is a normal operating state, in which the control unit releases a heating operation for the placement unit regardless of the placement unit characteristic. A “normal operating state” refers in particular to an operating state in which the control unit in particular releases a heating operation and/or at least one cooking function that is different from an operating state regardless of an identity of at least one placement unit. This in particular allows a high level of flexibility to be achieved, as a plurality of placement units in particular can be heated and/or a plurality of cooking functions that are different from an operating state can be selected.
In particular the control unit switches between safe operating state and normal operating state as a function of the input identification characteristic, thereby allowing significant ease of operation and/or simple and/or intuitive operation.
It is also proposed that the control unit monitors an in particular manual heating operation for the placement unit in at least one cooking function, in particular in the cooking function configured as a safe operating state, and initiates at least one safety action to avoid overheating in the event of in particular imminent overheating. In particular the cooking system has at least one sensor unit, which is provided in particular to detect at least one sensor characteristic, which in particular identifies and/or characterizes and/or forms and/or defines at least one operating parameter. The operating parameter could be for example a temperature and/or a weight and/or a cooking state and/or a boiling state. For example, the cooking state and/or boiling state could be simmering and/or poaching and/or boiling over and/or boiling and/or gentle boiling. The sensor unit is provided in particular to detect an in particular imminent overheating by means of at least one temperature measurement and/or by means of at least one measurement of an acceleration characteristic and forward it in particular to the control unit. This in particular ensures a high level of safety and/or prevents boiling over and/or overheating, in particular for elderly and/or forgetful people, for whom in particular there might be a high risk of forgetting the placement unit on the cooking surface.
The safety action could be in particular outputting a warning and/or an operating prompt. The safety action is preferably the termination of the heating operation for the placement unit, in particular by deactivating at least one heating unit and advantageously at least most and particularly advantageously all the heating units heating the placement unit. This results in a safe embodiment and/or safe operation, in which it is possible in particular to avoid boiling over and/or overheating.
It is also proposed that at least one cooking function is an automatic cooking program, in which the control unit executes at least one cooking function that is different from an operating state in particular automatically and advantageously heats the placement unit automatically and in particular prepares items to be cooked that are present in the placement unit. This in particular ensures significant ease of operation. For example the control unit could have at least one timer and be provided in particular to finish cooking and/or preparing items to be cooked at an in particular manually preset time by means of the cooking function that is an automatic cooking program, with the result that an operator can eat the prepared food in particular at the preset time, even though said operator might in particular be unable to do so in a time period immediately preceding the preset time.
For example, at least one identification characteristic could be a fingerprint and/or facial recognition and/or speech recognition. At least one and in particular the identification characteristic is preferably a password that can be input in particular manually. A “password” refers in particular to a series of at least two, in particular at least three, advantageously at least five, preferably at least eight and particularly preferably multiple figures and/or letters and/or special characters and/or punctuation marks. This in particular ensures a high safety standard and/or allows a high level of flexibility. In particular a separate identification characteristic can easily be provided for each placement unit, thereby allowing a cooking function to be released specifically in particular for any placement unit.
The control unit could for example be configured at least partially as a mobile device control unit and in particular be integrated at least partially, advantageously at least largely in at least one mobile device. The control unit is preferably configured at least partially as a cooktop control unit and is in particular integrated at least partially, advantageously at least largely and particularly advantageously completely in at least one cooktop. In particular the cooktop control unit is integrated at least partially, in particular at least largely and advantageously completely in at least one control unit of a cooktop. The expression that an object is configured “at least partially” as a cooktop object means in particular that at least part of the object is configured as part of the cooktop object and in particular is integrated in the cooktop object. For example, at least a further part of the object could be configured as an appliance object that is different from a cooktop object, for example as a mobile device object. The expression that an object is “configured as a cooktop object” means in particular that the object is integrated in at least one cooktop. This means in particular that few parts are required and/or storage outlay is reduced.
The operator interface could be configured for example at least partially as a mobile device operator interface and be integrated in particular at least partially, advantageously at least largely in at least one mobile device. The operator interface is preferably configured at least partially as a cooktop operator interface and is integrated in particular at least partially, advantageously at least largely and particularly advantageously completely in at least one cooktop. The operator interface in particular has at least one output unit and advantageously at least one display unit. In particular the operator interface has at least one liquid crystal display. In particular the cooktop operator interface is integrated at least partially, in particular at least largely and advantageously completely in at least one operator interface of a cooktop. This means in particular that few parts are required and/or storage outlay is reduced.
A particularly high level of safety and/or reduced storage outlay can be achieved in particular by a cooktop, in particular an induction cooktop, with at least one control unit of an inventive cooking system, which has at least one control unit interface and is provided to communicate with the operator interface by way of the control unit interface. In particular the control unit is provided to receive at least one characteristic from the operator interface and/or to transmit at least one characteristic to the operator interface by way of the control unit interface. The cooktop could in particular comprise only the control unit and/or the operator interface of the cooking system. The cooktop could advantageously comprise in particular the entire cooking system.
Alternatively the cooking system could for example comprise at least one and in particular the cooktop, in which in particular at least one control unit and/or at least one operator interface of an inventive cooking system could be integrated at least partially, in particular at least largely and advantageously completely.
An extremely high degree of safety can be provided in particular by a method for operating an inventive cooking system, with which at least one cooking function can be released and/or blocked for the placement unit as a function of at least one identification characteristic for at least one placement unit input by way of at least one operator interface.
The cooking system here is not restricted to the application and embodiment described above. In particular the cooking system can have a number of individual elements, parts and units that is different from the number cited herein to comply with a mode of operation described herein.
