7536881 - Linen treatment device with imbalance monitoring, level monitoring or load monitoring - Owned by BSH Bosch und Siemens Hausgeraete GmbH (Munich,DE)

The invention relates to an acceleration sensor for a household device (20) which serves for levelling the appliance and also for weighing the material introduced into the appliance, for example on a laundry unit or crockery and furthermore, in particular for a linen treatment device, for monitoring imbalances. The sensor is based on the principle that a temperature profile, generated by a thermal source, for example, an immersion heater (5), in a scaled chamber (6) which contains a gas, undergoes a displacement as a result of the acceleration, which is measured by temperature sensors arranged on a flat plate (4).
