Abstract
An acceleration sensor for a household device which serves for leveling 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 in a sealed chamber which contains a gas, undergoes a displacement as a result of the acceleration, which is measured by temperature sensors arranged on a flat plate.

1-18. (canceled)
A household appliance comprising:
- at least one sensor that measures a temperature profile of a heating device integrated in the sensor,
- wherein the temperature profile changes based on an acceleration of the household appliance,
- wherein the temperature profile changes based on a position of the household appliance with reference to a direction of a vector of acceleration due to gravity, and
- wherein the at least one sensor outputs a sensor signal for leveling the household appliance;
- and
- a display connected to the at least one sensor that receives the sensor signal and displays instructions on an adjustment of the household appliance,
- wherein the displayed instructions include a deviation of the household appliance from a horizontal position.
A linen treatment device, comprising:
- a soapy water container;
- and
- an arrangement for determining an imbalance of the soapy water container, the arrangement including:
- a lever device coupled to the soapy water container;
- and
- a sensor coupled to the lever device, wherein the sensor measures a temperature profile of a heating device built into the sensor,
- wherein the temperature profile of the heating device is altered by acceleration resulting from the imbalance of the soapy water container such that the imbalance of the soapy water container is determinable by the sensor.
