  • Patent number: 5249749
    Abstract: A self-cleaning garbage disposal utilizes a spray ring which is located below the splash guard. A control valve is connected to the cold water pipe and controls the flow of water from the cold water line into the spray ring. The control valve is engaged simultaneously with the disposal when the disposal is activated, which also initiates a timer control circuit on the control valve. The spray ring, using standard water pressure, forces the food debris directly into the disposal blades in a counterclockwise direction for faster and more efficient grinding of the food debris. When the disposal is switched off, water continues to flow through the spray ring for approximately fifteen seconds, thoroughly flushing any remaining debris down the drain.
