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: In a method to dehumidify a cooking chamber of a domestic cooking appliance, a condensation formation in the cooking chamber is ascertained. A dehumidification message connected to a dehumidification process is displayed when the condensation formation is detected, and a user action is awaited when the message is displayed. The dehumidification process is either performed or terminated depending on the user action. A domestic cooking appliance includes a cooking chamber and a display device and is configured to ascertain a condensation formation in the cooking chamber and to start a dehumidification process when the condensation formation is ascertained. The domestic cooking appliance is additionally configured to display a drying message connected to a dehumidification process on the display device prior to starting the dehumidification process, to await a user action when the dehumidification message is displayed, and either to perform or terminate the dehumidification process depending on the user action.
