In a method for detecting spark-overs in a treatment compartment of a household microwave appliance during a microwave treatment process, a setting value of a microwave operating parameter can be varied during the microwave treatment process. During the microwave treatment process, measurement values of a leakage radiation are measured several times in succession under same setting values of the microwave operating parameter, and a spark-over is detected when a fluctuation range of the measurement values achieves or exceeds a predetermined fluctuation range.

In a method for operating a household microwave appliance, a microwave treatment operation is controlled as a function of a temperature of a microwave generator. The household microwave appliance includes a cooking chamber, a microwave generator for routing microwaves to the cooking chamber, a temperature-determining apparatus for determining a temperature of the microwave generator, a microwave distribution device designed to change a field distribution in the cooking chamber during a microwave treatment operation, and a control device designed to control the microwave treatment operation as a function of the temperature of the microwave generator effected by a change in the field distribution.

A microwave household appliance with at least one microwave source for generating microwaves, at least one microwave antenna for irradiating the microwaves in a treatment room and a control device for controlling the microwave household appliance based on quantized microwave parameters.

Operating a domestic microwave appliance

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.

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.

A cooking appliance includes a cooking chamber wall delimiting a cooking chamber and including an opening, and a motor-movable changing device arranged outside the cooking chamber and including at least two sensor units for detecting a property of the cooking chamber. The changing device can be set in such a way by motorized movement that one of the at least two sensor units can be positioned in front of the opening at a time for detecting the property of the cooking chamber through the opening.

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.

A network-compatible household appliance includes a communications facility for coupling via a data link to an external database. The household appliance is configured to receive operating parameters relevant for an operating sequence from the database via the communications facility, to store the operating parameters for implementing the operating sequence by the household appliance, and, when triggered by a user, to automatically transfer the operating parameters for the operating sequence to the database via the communications facility.

A microwave cooking appliance includes a cooking chamber delimited by a cooking chamber wall, and a microwave apparatus configured to introduce microwaves into the cooking chamber. The microwave apparatus includes a patch antenna having a planar base body and a planar emission body, which are electrically insulated from one another. The emission body is configured to cover the base body at a distance and capable of being fed with microwave energy, with the base body corresponding to a region of the cooking chamber wall.

A microwave cooking appliance includes a door which covers a loading opening of a cooking chamber when closed, and has a profiled trap structure to form with an electrically conductive door flange a lambda quarter-wave trap that frames the loading opening. The trap structure includes a metal choke profile with an open face opposite the door flange, inner and outer metal tongues protruding into the open face laterally on an inside and outside, respectively. The metal tongues are connected electrically to the choke profile and separated from one another by a microwave entry slot covered by a microwave-transparent cover. The choke profile is framed laterally on the outside by a parallel overlap region which protrudes from the door flange and has a cover surface facing the door flange at a distance and made of electrically conductive material and having a same shape as a door flange region it covers.

A household cooking appliance includes a cooking space and a microwave apparatus which is configured to feed microwaves into the cooking space. The microwave apparatus includes a feed chamber arranged outside of the cooking space and configured to open into the cooking space through an emission opening which is excitable by the microwaves, and a microwave line projecting into the feed chamber and connected galvanically to an electrically conductive wall region of the feed chamber which wall region restricts the emission opening. The feed chamber defines a chamber which is non-resonant for the microwaves.
