    cooking of the cooking space when addressing and / or regulating the temperature of the muffle wall. In this way, great comfort of use can be achieved. In particular, an optimal regulation of the power supplied to the cooking product and / or an optimal cooking result is possible, independently of other variables such as, for example, the type of cooking product and / or the objects located in the cooking space and / or the position of at least one sensor unit within the cooking space. It is possible to adjust and / or optimally influence the degree of roasting of the cooking product, for example, of a cooking product that is a pizza, by means of the power supplied to the cooking product.
    As an example, the control unit could be provided to determine in any operating mode the power supplied to the cooking product disposed within the cooking space, depending on the temperature detected by the same sensor unit. Preferably, the control unit is provided to determine the power supplied to the cooking product disposed within the cooking space in different operating modes depending on the temperatures detected by the different sensor units. Specifically, the control unit is intended to take into account different types of power supplied to the cooking product when determining the power supplied to the cooking product disposed within the cooking space. The type of power supplied to the cooking product could, for example, be a power based on convection and / or a power based on thermal radiation and / or a power based on thermal conduction. When determining the power supplied to the cooking product disposed within the cooking space, the control unit is intended to determine at least one power based on convection and / or one power based on thermal radiation and / or one power based on the thermal conduction and to differentiate them from each other. Specifically, the control unit is intended to take into account the temperature detected by the second sensor unit and / or the temperature detected by the third sensor unit when determining the power supplied to the cooking product disposed within the cooking space. In this way, the different proportions of the power supplied to the cooking product can be estimated, for example, a proportion of power based on convection and / or a proportion of power based on thermal radiation, compared to an embodiment in the that only the total power supplied to the cooking product can be estimated. The user can select at least one mode of operation in which the control unit also estimates different proportions of the power supplied to the cooking product next to the temperature within the cooking space, so that comfort of use can be achieved particularly elevated in

    comparison with an embodiment in which the user has to select a predefined combination of heating element and fan unit. The evaporation of water, which depends largely on the type of power supplied to the cooking product, can be controlled and / or regulated very well, and even better if at least one sensor unit has at least one humidity sensor.
    In addition, it is proposed that the control unit be provided to take into account the emissivity of the muffle wall when determining the power supplied to the cooking product disposed within the cooking space. The muffle wall and / or a muffle wall covering have an emissivity of at least 0.8, preferably, at least 0.85, advantageously, at least 0.9, particularly advantageously, of at least 0.95 and, preferably, at least 0.97. As an example, the muffle wall and / or a muffle wall covering could be largely or completely a black body and have an emissivity of at least 0.99. The muffle wall could have at least one coating that could be composed at least largely of enamel. The emissivity of an object is the degree of emission of the object. In this way, the power supplied to the cooking product disposed within the cooking space can be determined particularly precisely.
    Particularly high operating comfort can be achieved by means of a cooking appliance, in particular, by an induction cooking appliance and, advantageously, by an induction cooking oven, with at least one cooking appliance device according to the invention, in particular, with at least one induction cooking device according to the invention and, advantageously, with at least one induction cooking device according to the invention.

    Here, or is the constant of Stephan Boltzmann. £ is the emissivity of the muffle wall 14. Atop is the surface of the muffle wall 14 made as a muffle cover wall 38. F is a factor that is dependent on the geometry of the muffle 12. Ttop is the temperature detected by the sensor unit 20. Tfood is the temperature detected by the third sensor unit 28.
    In the thermal radiation mode of operation, the control unit 30 uses the following formula to determine the power supplied to the cooking product 52 disposed within the cooking space 16, which constitutes a sufficient approximation to the formula used as the starting point :
    Qrad ® ^ rad * Otop ^ "food}
    Here, krad is a known coefficient, which is stored in a storage unit of the control unit 30 and which is determinable by experimental tests and / or by theoretical calculations.

    The emissivity of the muffle wall 14 is included in the known coefficients. In the operating state, the control unit 30 takes into account the emissivity of the muffle wall 14 when determining the power supplied to the cooking product 52 disposed within the cooking space 16.
    In a mixed mode of operation, the control unit 30 takes into account the power based on the thermal radiation and the power based on the convection when determining the power supplied to the cooking product 52 disposed within the cooking space 16. In the mode In mixed operation, the heating element 18, the other heating element 24 and the fan unit 48 are activated.
    When determining the power supplied to the cooking product 52 disposed within the cooking space 16, the control unit 30 could, for example, take into account the power based on thermal conduction in at least one mode of operation, in particular in the mode of operation by convection and / or in the mode of operation by thermal radiation and / or in the mode of mixed operation. In this exemplary embodiment, the control unit 30 does not take into account the power based on the thermal conduction when determining the power supplied to the cooking product 52 disposed within the cooking space 16.
    In the thermal radiation mode of operation, the control unit 30 could, for example, take into account additionally the convection, in particular the natural convection, when determining the power supplied to the cooking product 52 disposed within the cooking space 16 .
    In a procedure for putting the cooking apparatus device 10 into operation, the temperature of the muffle wall 14 in the operating state is measured. The power supplied to the cooking product 52 disposed within the cooking space 16 is determined depending on the temperature of the muffle wall 14.
    In the operating state, the control unit 30 uses the temperature within the cooking space 16 detected by the second sensor unit 26 and / or the temperature detected by the sensor unit 20 for safety related purposes. A reference value for the temperature detected by the second sensor unit 26 and / or by the sensor unit 20 is stored in a storage unit of the control unit 30. The reference value for the temperature detected by the second sensor unit 26 and / or by the sensor unit 20 indicates the maximum allowed temperature within the cooking space 16. In the operating state, the control unit 30 reduces the power
    supplied to the heating element 18 and / or the other heating element 24 as soon as the temperature detected by the second sensor unit 26 and / or by the sensor unit 20 reaches the reference value (see Figure 3). In this case, the control unit 30 directs and / or regulates the temperature within the cooking space 16 and / or the temperature of the muffle wall 14 at the reference value.
    In addition to the operation modes described, at least one other mode of operation could be stored by way of example in a storage unit of the control unit 30, in which the control unit 30 could operate the heating element 18 and / or the other heating element 24 depending on the temperature within the cooking space 16.
