  • Dishwasher with rinse diverter for reducing detergent consumption
    Patent number: 5899215
    Abstract: A diverter member is installed in a dishwasher to reduce detergent consumption therein. The diverter member includes an upwardly disposed liquid receiving surface in fluid communication with a drain for receiving a portion of the rinse liquid sprayed on dishware in a rinse section of the dishwasher to increase the amount of rinse liquid communicated to the drain. A lesser amount of rinse liquid returns to the wash tank, thereby reducing dilution of the wash liquid and consumption of detergent.
