Abstract: A method for temperature measurement in a household appliance includes generating a high-frequency electromagnetic excitation wave of a predefined transmit frequency. The transmit frequency is selected from a frequency band including temperature-dependent resonant frequencies that occur in a surface wave device incorporated in a temperature measuring probe and which respectively correspond to temperatures expected at the temperature measuring probe during operation of the household appliance. During a first phase, the excitation wave is wirelessly transmitting to the surface wave device. During a second phase following the first phase, an electromagnetic response wave generated by the excitation wave in the surface wave device is wirelessly transmitting to a processing unit.

Abstract: A method for controlling the temperature of a baking oven having a catalyst, a heating source, an oven chamber temperature sensor, and a catalyst temperature sensor, includes generating an electrical control signal based on a control state, the control state being a function of signals from the electrical sensors and being reached when the catalyst temperature is higher than the oven chamber temperature and the temperature difference between the catalyst temperature and the oven chamber temperature is greater than or equal to a threshold value.

Abstract: A method for controlling a cooking process in a cooking appliance having a sensor for measuring a gas concentration in the cooking chamber and an electric or electronic control system in communication with the sensor and including an evaluation circuit and a memory, includes ascertaining, as a function of a food to be cooked, a cooking end value stored in the memory. An output signal of the sensor is processed using the evaluation circuit so as to generate a cooking quotient. The cooking quotient at a point in time corresponds to a ratio of the first derivative of the output signal with respect to time to a first extreme value of the first derivative of the output signal with respect to time. A value of the cooking quotient is compared to the cooking end value using the evaluation circuit, and an appliance function is triggered.

Abstract: A method for determining a surface tension of a solution in a container using a bubble pressure process includes introducing a gas volume flow into the solution using a capillary. A time-dependent pressure profile of the gas volume flow is determined during bubble formation using a pressure sensor. The gas volume flow is interrupted toward the end of the determination process by closing the capillary over the entire cross section of the capillary over at least a part of the length of the capillary.

Abstract: A door for a household appliance includes a door frame, a pane and a clamping device for detachably securing the pane to the door frame. The door frame includes a first and a second holding member disposed opposite each other. The clamping device includes an elastic element located at the first holding member and a clamping element located at the second holding member when the door is in an assembled state. The clamping element is movable from a released position to a locking position so as to detachably mount the pane. The pane is located, with play, between the elastic element and the other holding member when the clamping element is in the released position. The clamping element, when in the locking position, engages a gap between the second holding member and a front face of the pane so as to press the pane against the elastic element.

Abstract: A household food warmer for keeping foods and beverages warm includes a housing, a drawer which can be inserted into the housing, an interior chamber which is bounded by the housing and the inserted drawer and which is used to accommodate foods placed on plates, a heating element, an electrical circuit in which is arranged a first electrical switch for switching on the heating element, and a temperature sensor for measuring the interior chamber temperature. A convection fan is provided. The convection fan can be switched on via a second electrical switch arranged in the electrical circuit and can be switched off via the second electrical switch upon the occurrence of a switching condition that is dependent on the temperature sensor.

Abstract: An adjusting device for a gas cooking appliance for adjusting the gas flow rate includes a distribution inlet conduit in fluid communication with a gas supply line of the gas cooking appliance, and a distribution outlet conduit in fluid communication with a gas burner line of the gas cooking appliance.
