No-spray-arm-rack-based pressure wash system for dishwashers

Abstract

A dish rack consists of horizontal and vertical water conduits, with a plurality of vertical water conduits connected to each horizontal water conduit. Each vertical water conduit has a number of upward angled water nozzles. A water supply switch box is connected to said dish rack. Said switch box is connected to a water pump through an extendible hose. Said switch box directs pressured water to two said horizontal water conduits on said dish rack at a time. Pressured water is then forced out through nozzles on said vertical water conduits. Kitchen ware is washed directly by pressured water.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to the drawings, FIG. 1 shows a dish rack with the conventional structure but with horizontal and vertical water conduits. The solid grid lines help reinforce the structure and hold the kitchen ware. The horizontal and vertical water conduits transport and direct water towards the kitchen ware through nozzles on the vertical conduits.

FIG. 2 shows the vertical water conduits with nozzles spread around and directed upwards at various degrees. The water nozzles are randomly distributed so adjacent vertical water conduits together can cover as much surface of an item to be washed as possible. It's important to have the top nozzle to prevent buildup of food scraps in the conduit.

FIG. 3 shows the bottom of the dish rack connected to the first plate of the water supply switch box. Please note that each horizontal water conduit is blocked in the middle to form two separate halves, in order to reduce travel distance of water flow and maximize water pressure. Each half of the horizontal conduit is connected to one water outlet on the first water switch plate.

FIG. 4 shows the geared second water supply switch plate engaged with the geared turbine axle. The water supply outlets on the first switch plate are represented by dotted circles. When the turbine turns, the turbine axle causes the second plate to rotate. There is an opening on the second plate that covers two water outlets on the first plate. The size of the opening makes sure that there is at any time at least one water outlet on the first plate open to enable water flow.

FIG. 5 is a perspective view of the water intake opening, the turbine and the second water switch plate. The water intake opening is connected to the water pump through an extendible hose. When pressured water enters the switch box from the pump, the turbine is caused to turn, which in turn causes the second water switch plate to rotate. When the second plate rotates, the opening on the second plate is moved to the next water outlets on the first plate and directs water to two outlets at a time.

While the forms of apparatus disclosed herein constitute preferred embodiments of the present invention, those knowledgeable in the art understand that the invention is not limited to these precise forms of apparatus, and that changes may be made therein without departing from the scope of the invention as defined by the appended claims.

Claims
