1. A household appliance, comprising:
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;
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,
wherein the pattern luminaire includes a light source for generating a light bundle and an optical element, which is arranged optically downstream of the light source, for generating the light pattern from the light bundle emitted by the light source, and
a rotatable microwave antenna which includes a hollow shaft mounted for rotation about a longitudinal axis thereof for feeding microwaves into the treatment chamber, said optical element of the pattern luminaire being accommodated in the shaft of the microwave antenna.
