Household appliance with imaging laser scanner module

摘要

A household appliance (1) has a treatment room (4) that can be locked by means of a door and an imaging laser scanner module (5) for recording a reflection image from the treatment room (4), which laser scanner module (5) has a laser scan projector (13) for beaming a scanning laser beam into the treatment room (4) and at least one light sensor (16) for detecting laser light reflected from the treatment room, the laser scanner module (5) having a deflection mirror (14) which is set up to deflecting laser light emitted by the laser scan projector (13) into the treatment room (4), at least one information area is optically generated on a surface (7-10) of the treatment room (4) by means of the laser scanner module (5) and the household appliance (1 ) is set up to recognize at least one user interaction on the information area from the reflection image. In a method for operating the household appliance, at least one information area can assume an active or passive state and is generated with different brightness depending on its state. The invention is particularly advantageously applicable to refrigerators, in particular refrigerators.
