In a method for determining a temperature of a revolving drum of a laundry dryer, said drum has an outer wall and thereon at least one strip-shaped delimited detection region comprising thermochromic material having a transition temperature in the range of a temperature that is to be expected and to be determined. Optical detection means arranged adjacent to the revolving part are configured, in particular as a reflected light barrier, to detect the color transition of the thermochromic material in the event of the transition temperature being exceeded or undershot. At the revolving drum the thermochromic material or, if appropriate, the color transition thereof is detected by means of the detection means. A temperature of the drum is then determined as corresponding to the transition temperature in such a way that the temperature thereof is determined as corresponding to one of the two temperature ranges below the transition temperature or above the transition temperature.

A method for controlling a cooking appliance using a mobile terminal that is separate from the cooking appliance, both of which have a controller and a BLE communication device, involves the following steps being performed: switching on the cooking appliance and the terminal, setting up a communication link between the two by means of a specified user process on the cooking appliance or on the terminal and confirming the set-up of the communication link by means of a user process by the user on the cooking appliance. A signal strength of the communication link between the two communication devices at the time of confirmation of the communication link on the cooking appliance is stored and is monitored during use. If the signal strength drops below a prescribed signal strength limit value, then user commands from the mobile terminal are blocked.

A temperature measuring device for an electric appliance such as a fryer includes at least one temperature sensor in the form of an electric resistor, to which at least two different measuring voltages can be applied with cyclic switching between the measuring voltages. The temperature sensor is connected to a control, which includes a microcontroller and which is configured for applying at least two different measuring voltages to the temperature sensor.

An arrangement for controlling electrically controllable appliances, such as electric cookers, has at least one manually operable control element placed on an outside of a plate, e.g. a glass ceramic plate of an electric cooker, which is secured by a magnetic holding device in non-contacting magnetic manner on the plate. A sensor device determines the position and/or position change of the control element and an associated control device, in order to set different operating modes of the appliance. The control element is constructed as a sliding key automatically returning to a rest position and which is displaceable in at least one displacement direction along the plate. Such sliding keys can be operated in a particularly easy manner and are well adapted to an at least partial digital processing of the sensor signals to controlling signals.
