Thermoelectric drive apparatus, in particular for the actuation of distributors for washing and/or sparkling agents in automatic washers

摘要

To increase the reliability of the distributing function of auxiliary automatic washer units and for eliminating otherwise occurring sources of noise, the thermoelectric drive apparatus comprises a stabilised thermistor (14), which is enclosed in the housing (5) of the drive device and is embedded in a solid, low-viscosity or liquid substance having a high coefficient of thermal expansion, the changes in volume of which are transmitted to moving mechanical elements for controlling the distributor arranged in the automatic washer. <IMAGE>
