ABSTRACT:
An improved water temperature control and method for automatic clothes washers having a tub for containing water and a water valve with a hot water inlet and a cold water inlet, a temperature sensing control including a temperature responsive switch for controlling at least one of the water inlets, a water conduit from the water valve to the tub. The improvement is a water sampling tank having an inlet, an outlet, and a water chamber therebetween, the tank being arranged in water flow communication with the conduit between the water valve and the tub so that a small portion of water passing through the conduit is diverted through the chamber. The water temperature responsive switch is in temperature sensing relationship with the water in the chamber. The improved water temperature control and method minimizes the amount of cycling of the temperature responsive switch and the water valve solenoids while maintaining accurate control of the desired water being introduced from the water valves into the clothes washer tub.
