ABSTRACT:
A refrigerator includes a water dispensing system which includes a receptacle removably disposed within a refrigerating compartment of the refrigerator. A valved feed duct extends into the refrigerator for supplying fresh water to the receptacle when the water level in the receptacle falls below a predetermined level. An ultrasonic water level detector determines when the water level falls below the predetermined level and sends a signal to a controller which then opens the valved feed duct.
