Fig. 1 shows a cooking appliance according to the invention 24a, which is designed as a hob, with a cooking appliance device 10a according to the invention, which is designed as a hob device. As an alternative to a design as a hob, the cooking appliance 24a could be designed as oven, microwave oven and / or mixer. Also conceivable are other cooking appliances that appear appropriate to a person skilled in the art. The cooking device device 10a has a main body 26a for setting up the cooking containers 22a. The main body 26a forms a cooking surface. The cooking device device 10a has a plurality of heating elements (not shown), which are arranged below the main body 26a. The heating elements, which are designed as induction heating, are to provided to heat on the base body 26a above the heating elements raised cooking container 22a. In the present embodiment, the cooking container 22a is designed as cooking utensils, for example as a pot, pan or steamer. Alternatively, further cooking containers appearing appropriate to a person skilled in the art are conceivable. The cooking appliance device 10a comprises a power supply 18a for supplying the heating elements. The power supply 18a supplies the heating elements with high-frequency alternating current. The cooking appliance apparatus 10a has an operating unit 28a for inputting operating parameters in an area assigned to an operator in the installed state. For example, the operating parameters are designed as a selection and / or change of a heating zone and / or as a setting of a heating power and / or heating power density of a heating zone. Furthermore, the cooking device device 10a has a cooking appliance control unit 30a which is provided to execute actions and / or to change settings in dependence on the operating parameters entered by means of the operating unit 28a.

The cooking device device 10a has a plurality of ultrasonic generators 12a for generating ultrasound (cf. Fig. 2 ). The ultrasonic generators 12a are arranged on the main body 26a. In this case, the ultrasonic generators 12a are arranged below the main body 26a. Each ultrasonic generator 12a is partially disposed within a heating zone. For example, each ultrasonic generator could be partially disposed within one of the heating elements. In this case, each of the ultrasonic generators could be arranged substantially in a center of one of the heating elements, wherein the ultrasonic generator could be surrounded by an induction heating coil wound as a coil. The ultrasonic generators 12a are separated from the base body 26a by a raised cooking container 22a. In an operating state, the ultrasonic generators 12a are arranged in a vicinity 20a of the cooking container 22a.

The cooking device device 10a comprises a control unit 14a for controlling the ultrasound generator 12. The control unit 14a is formed essentially in one piece with the cooking appliance control unit 30a. Alternatively, it is conceivable that the control unit and the cooking appliance control unit are formed separately. For example, it is conceivable that the control unit is formed substantially in one piece with the ultrasonic generators. Also conceivable are further arrangements of the control unit that appear appropriate to a person skilled in the art.

The cooking device device 10a has a plurality of sensor units 16a for detecting a temperature of the food. The sensor units 16a are arranged in an operating state in the vicinity 20a of the cooking container 22a. The sensor units 16a are arranged in a built-in state in a vicinity of the ultrasonic generator 12a. The sensor units 16a are arranged in the installed state on the ultrasonic generators 12a. Alternatively, it is conceivable that the sensor units are arranged in the installed state in the ultrasonic generators. Here, each sensor unit 16a is formed substantially in one piece with one of the ultrasonic generators 12a. The sensor unit 16a comprises a sensor element designed as an infrared sensor for detecting the temperature of the food. Alternatively, further embodiments of the sensor element that appear appropriate to a person skilled in the art are conceivable. The sensor unit 16a comprises a transmission module for transmitting the detected temperature of the food to the control unit 14a. The control unit 14a comprises a receiving module for receiving the temperature transmitted by the sensor unit 16a.

In a method for operating the cooking device device 10a, a raised cooking container 22a is heated by means of the heating elements, whereby a cooking process is started. In this case, the control unit 14a operates the power supply 18a to supply the heating elements. The control unit 14a operates the ultrasonic generators 12a to influence a cooking process of a partially-fluid cooking product located in the erected cooking container 22a. In an operating state in which the ultrasonic generators 12a are operated by the control unit 14a, the ultrasonic generators 12a transmit ultrasonic energy generated to the cooking container 22a via the main body 26a acting as the coupling medium. The control unit 14a changes a pressure distribution of the food by means of the ultrasonic generators 12a. The control unit 14a generates by means of the ultrasonic generators 12a pressure fluctuations in the cooking product located in the cooking container 22a. Due to the pressure fluctuations, a disintegration of larger gas bubbles, which form due to heating in the food to be cooked, is excited into smaller gas bubbles. By the pressure fluctuations generated by means of the ultrasonic generator 12a, a size of the gas bubbles and a homogeneity of the food are changed. By means of the ultrasonic generators 12a, the control unit 14a changes a density distribution of the food. The control unit 14a substantially avoids overcooking of the food by means of the ultrasonic generators 12a. By means of the ultrasonic generator 12a caused pressure fluctuations changed the control unit 14a further parameters of the food. The other parameters are designed as thermal diffusivity and as chemical properties of the food. Also conceivable are further parameters that appear appropriate to a person skilled in the art.

The control unit 14a operates the ultrasonic generators 12a as a function of the temperature of the food (cf. Fig. 3 ). For example, a cooking process is started at time t ₀ by heating an upright cooking container 22 a, in which the partially fluid food is to be cooked, by means of the heating elements. At time t ₀ , the control unit 14a starts to operate the heating elements by means of the power supply 18a. For this purpose, the control unit 14a uses alternating current with a frequency f (cf. Fig. 3 ). As a result, a temperature of the food rises from a temperature T _{0 of} the food. The control unit 14a compares the value of the temperature of the cooking product detected by the sensor unit 16a with a comparison value T ₁ > T ₀ stored in a storage unit of the control unit 14a. At time t ₁ > t ₀ , the temperature of the food reaches the comparison value T ₁ . The temperature of the food at time t ₁ assumes a value T = T ₁ . The comparison value T ₁ is smaller than a boiling temperature T _{2 of} the food. Upon reaching the boiling temperature T ₂ sets in the food without interference by means of the ultrasonic generator 12a blistering. If the temperature of the cooking product is greater than or equal to the temperature of the comparison value T ₁ , then the control unit 14a operates the ultrasonic generators 12a to influence the cooking process of the partially-fluid cooking product. The control unit 14a starts to operate the ultrasonic generators 12a to influence the cooking process of the partially-fluid cooking product before the onset of bubbling in the food to be cooked.

The control unit 14a operates the ultrasonic generators 12a at substantially the same frequency as the power supply 18a, the heating elements, by means of which the food to be influenced by the ultrasonic generators 12a is heated (cf. Fig. 3 ). The control unit 14a uses pulsed ultrasound generated by the ultrasonic generators 12a to influence the cooking process of the food. The ultrasonic generators 12a are operated by the control unit 14a by means of the power supply 18a in an operating state in which the ultrasonic generators 12a influence the cooking operation of the food. Each of the ultrasonic generators 12a has in one Operating state in which the ultrasonic generator 12a affects the cooking process of the food, a consumption of at most 200 W. A utilization of the operated ultrasonic generator 12a is dependent on several parameters. For example, the utilization of the operated ultrasonic generator 12a depends on the properties of the food to be cooked, properties of the cooking container 22a and / or heat transfer. Properties of the food are, for example, viscosity, density, heatability, protein content, phase distribution, bubble formation, bubble distribution, size of the bubbles and / or homogeneity of the food. Properties of the cooking container 22a are, for example, size, shape, material and / or filling state. At full capacity of the powered ultrasonic generator 12a, the ultrasonic generator 12a has a consumption of 200W.

The cooking appliance apparatus 10b includes a control unit 14b for controlling the ultrasonic generator 12b.

Thus, the control unit 14b is formed separately from a cooking appliance control unit 30b of the cooking appliance apparatus 10b. The control unit 14b is provided for wireless communication with the cooking appliance control unit 30b. The control unit 14b is disposed in the vicinity 20b of the cooking container 22b.

The control unit 14b changes a pressure distribution and a density distribution of the food by means of the ultrasonic generator 12b.

The control unit 14b operates the ultrasonic generator 12b as a function of the temperature of the food (cf. Fig. 3 ). The control unit 14b begins to operate the ultrasonic generator 12b to influence the cooking process of the partially fluid cooking product before the onset of bubbling in the food. The control unit 14b operates the ultrasonic generator 12b at substantially the same frequency as the power supply 18b, the heating elements, by means of which the cooking product affected by the ultrasonic generators 12b is heated (cf. Fig. 3 ). The control unit 14b uses pulsed ultrasound generated by the ultrasonic generator 12b to influence the cooking process of the food.
