    Abstract: A household microwave appliance includes a cooking chamber exposable to microwaves. A mode variation apparatus modifies a field distribution of the microwaves in the cooking chamber, and a microwave leakage sensor detects a microwave leakage radiation exiting from the cooking chamber. The household microwave appliance is designed to vary setting values of the mode variation apparatus, and to set an operating point of the mode variation apparatus based on a quantity of measurement data of the detected microwave leakage radiation resulting from a variation.

    Abstract: A household appliance includes a treatment chamber for treating material, a pattern luminaire designed to radiate a light pattern into the treatment chamber, an image sensor directed into the treatment chamber for capturing the light pattern reflected from the treatment chamber, and a motor operably connected to the pattern luminaire for rotating the pattern luminaire into different angles of rotation so as to enable the household appliance to determine at least one item of contour information from material irradiated by the light pattern from at least two reflected light patterns associated with different ones of the angles of rotation of the pattern luminaire.

    Abstract: A household cooking appliance includes a cooking compartment wall delimiting a cooking compartment, a guide sleeve provided on the cooking compartment wall and having a cooking compartment-side end opening which opens into the cooking compartment, a sensor housed in the guide sleeve for longitudinal movement by motor power, and a closure element designed for movement by motor power together with the sensor between a closed position in which the closure element closes the end opening as the sensor is located in an end-opening-distal rest position, and an open position in which the closure element clears the end opening as the sensor is located in an end-opening-proximal measuring position.

    Abstract: A household microwave appliance operates with multiple parameter configurations to treat food to be cooked in a locally differing manner. The microwave appliance determines in an initial scan with a thermal imaging sensor directed into the cooking chamber a temperature distributions on a surface of the food to be cooked. Change patterns are obtained from differences between different temperature distributions. An evaluation value is calculated for a best heating pattern that brings the current temperature distribution closest to a target temperature distribution determined based on a normalized target state and a current temperature distribution, whereafter microwave power is applied to the food to be cooked with the parameter configuration associated with the best heating pattern.

    Abstract: A household microwave appliance includes a cooking compartment, a cooking compartment wall surrounding the cooking compartment and including a cooking compartment opening, and a microwave dome arranged remote from the cooking compartment and designed to cover the cooking compartment opening. The microwave dome includes a first sensor opening and a second sensor opening, with a first sensor arranged behind the first sensor opening and oriented directly into the cooking compartment, and with a second sensor arranged behind the second sensor opening and oriented indirectly into the cooking compartment via a reflecting surface of the microwave dome.

    Abstract: In a method for treating food in a food handling device with a parameter configuration a measured value distribution of a surface property of the food is determined after expiration of the period of time by means of a sensor. A pattern of change is calculated from a comparison of the p-th measured value distribution with a measured value distribution determined previously. An assessment value Bq which represents a difference between a deviation of a target distribution from the measured value distribution and a deviation of the target distribution from a prediction pattern is calculated for all patterns of change stored hitherto. The prediction pattern is formed by superimposing the measured value distribution with the respective pattern of change, and the parameter configuration is set for which the assessment value Bq meets at least one predetermined criterion.
