- the known induction cooking utensils for induction cooking systems include, for example, an induction coil for inductive coupling to an inductive heating coil of the induction hob, a temperature sensor for detecting a temperature of the induction cooking utensil and a controller for evaluating output signals from the temperature sensor, the controller being connected to the temperature sensor in a signal-transmitting manner.
- the induction heating coil of the induction cooktop is also called the primary coil while the induction coil of the induction cookware is also called the secondary coil.
- the secondary coil has the task of providing an operating voltage for the cookware, for example for operating a motor or a heating device, or for the cookware electronics, for example for recording and processing sensor data, through the inductive coupling.
- the known induction cooking systems also include the aforementioned induction hob with the inductive heating coil.
- the documents DE 10 2010 039072 A1 , DE 10 2010 020189 A1 , DE 10 2015 222797 A1 , WO 2006/064386 A1 and WO 2013/098016 A1 disclose an induction cookware for an induction cooking system with an induction cooktop, comprising an induction coil for inductive coupling to an inductive heating coil of the induction cooktop for the purpose of providing an electrical voltage in the induction cookware, a temperature sensor for detecting a temperature of the induction cookware and a controller for evaluating output signals from the temperature sensor, wherein the controller is connected to the temperature sensor in a signal-transmitting manner.
- temperature regulation or temperature control when heating the cookware placed on the hob is desirable in order, for example, to increase ease of use for a user and/or to improve the quality of the cooking process.
- a precise as possible Temperature measurement on the cookware required.
- the invention therefore addresses the problem of improving temperature detection in an induction cookware.
- this problem is solved by an induction cookware with the features of patent claim 1, which is characterized in that the induction coil is designed as the temperature sensor and the induction coil can be controlled with a measuring DC voltage by means of the controller for the purpose of detecting the temperature of the induction cookware. Furthermore, this problem is solved by an induction cooking system having the features of patent claim 8 and a method for operating an induction cooking system having the features of patent claim 9 .

Due to the multiple use of the induction coil of the induction cookware, on the one hand, a reduction in components and, on the other hand, a space-saving design of the temperature sensor and thus of the induction cookware is made possible. Furthermore, the additional structural and circuitry complexity in the production of the induction cooking utensil according to the invention is reduced.
- the temperature detection of the induction cookware according to the invention is implemented independently of the induction cooktop of the induction cooking system, since the temperature of the induction cookware is detected entirely by means of the induction cookware.

- the temperature recorded by means of the induction coil represents a mean value over the entire induction coil, that is, for example, over an entire winding length of an induction coil designed as a winding. If the aforementioned winding forms a circle, for example, only the temperatures at the circular contact surface of the induction coil with the base are determined, ie only along a single radial distance from the center of the base of the induction cookware.
- the induction coil has a plurality of circular line segments which are electrically conductively connected to one another and arranged concentrically to one another.
