Valve assembly for use with a washing appliance
First Claim
1. A valve assembly for use with a washing appliance comprising a tub to receive only hot water and a main controller, said valve assembly comprising:
- a direct acting two-way hot water valve moveable between a first position that prevents hot water from flowing through a supply line and a second position that allows hot water to flow through the supply line to the tub; and
a control assembly configured to control said direct acting two way hot water valve to move between the first position and the second position to deliver a volume of hot water per fill cycle, said control assembly comprising;
a flow sensor configured to output a signal representing an amount of hot water flowing through the supply line;
a temperature sensor configured to measure a supply hot water temperature to the appliance; and
,a control unit configured to control said direct acting two way hot water valve to deliver a decreased volume of hot water per fill cycle if the measured supply hot water temperature is above a threshold temperature.

Abstract
A valve assembly for use with a washing appliance having a main controller includes a valve that is moveable between a first position that prevents water from flowing through a supply line and a second position that allows water to flow through the supply line. A control assembly separate from the main controller is configured to control the valve to move between the first position and the second position. The control assembly includes a flow sensor configured to output a signal representing an amount of water flowing through the supply line and a control unit configured to control the valve assembly based on the output signal of the flow sensor.

11. A valve assembly for use with a washing appliance comprising a main controller, said valve assembly comprising:
-
a direct acting two way valve configured to couple in flow communication with only a hot water supply line, said valve moveable between a first position that prevents hot water from flowing through the supply line and a second position that allows hot water to flow through the supply line; and a control assembly separate from the main controller and configured to control said direct acting two way valve to move between the first position and the second position to deliver a volume of hot water per fill cycle, said control assembly comprising; a flow sensor configured to output a signal representing an amount of hot water flowing through the supply line; a power supply configured to couple said control unit to the main controller; a temperature sensor configured to measure a supply hot water temperature to the appliance; and a control unit configured to control said direct acting two way valve to deliver a decreased volume of hot water per fill cycle if the measured supply hot water temperature is above a threshold temperature. - View Dependent Claims (12, 13)
