The utility device is described in an exemplary embodiment as being a warewashing machine that applies the chemical solution to articles provided to the machine on racks. The chemical solution is formed in a solution tank from a combination of at least one chemical product and at least one rinse agent. Whereas the chemical product is described as a detergent, the rinse agent is described as water. Over a time period including multiple wash cycles, the chemical product and the rinse agent are added to the solution tank, thereby changing conductivity of the chemical solution.

  • Patent number: 7958755
    Abstract: An acceleration sensor for a household device 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, 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.

  • Publication number: 20110088435
    Abstract: The invention relates to a housing device provided with a system for detecting the load applied to an element arranged in the housing, an internal part configured in such a way as to hold said element, and an external part for fixing the device to a mechanical group, the internal part being connected to the external part by at least two deformable connection parts in such a way that the internal part can be displaced in relation to the external part under the action of a load applied to the element. The system for detecting the applied load comprises a means for directly detecting the displacement of one of the parts, internal or external, in relation to the other part, external or internal, under the action of a load applied to the element.
