Abstract
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).
Claims18
A linen treatment device with an arrangement for determining the imbalance, characterised in that the arrangement has at least one sensor (14, 21, 22) to measure the temperature profile of a heating device built into the sensor (14, 21, 22), wherein the temperature profile can be altered by an acceleration caused by an imbalance.
The household device (20), especially a baking oven, especially according to at least one of the preceding claims, with at least one sensor (30, 31) for measuring a temperature profile produced by a heating device built in the sensor, wherein the temperature profile can be altered by the position of a sheet-metal guide frame (34) movable in the vertical direction by means of springs (35-38) in the household appliance.
The household device (20), especially a dishwasher, especially according to at least one of the preceding claims, with at least one sensor (40) for measuring a temperature profile produced by a heating device built in the sensor, wherein the sensor (40) is built in a spray arm (41) and the temperature profile can be altered by the rotating movement of the spray arm (41).
