Brush Based Dishwasher

Abstract

A dishwasher that uses the abrasive force of brushes to clean dishes. The dish is held in place from the top by a rack made of parallel bars so the top oscillating brush can pass through the rack and clean the outside of the dish. The dish is held in place below by the axle of the bottom rotating brush so the brush rotates to clean the inside of the dish. The dishwasher also consists of a rotating rack that holds the dish in place at the start and during the rinse cycle. The rotating rack consists of bars that support the dish, water slot to guide rinse water to the rinse chamber, and a moving cover that regulates the flow of the washing fluids to appropriate chambers.

Description

[0001]This application claims benefits to U.S. provisional patent application No. 61483743, May 9, 2011.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention pertains to the arts of dishwashers and, more specifically, to a brush based dishwasher.[0004]2. Discussion of the Prior Art[0005]The typical dishwashers consist of at least one dish rack, and at least one spray arm with multiple nozzles to direct fluids towards the dishes in the washing chamber. Due to various shapes of the dishes to be washed, and the proximity of the dishes to be washed, the fluid jets are oftentimes blocked so not to be able to reach the soiled dishes. For instance, a plate in front of another plate often blocks the fluid jets from reaching the second plate; the wall of a cup often blocks the fluid jets from reaching the interior of the cup. Only a fraction of the dish surface is reached directly with pressured fluids. Much of the dish surface is washed only with dripping flu...

AI Technical Summary

Benefits of technology

[0011]The new dishwasher consists of an oscillating brush on the top to clean the outside of dishes, a rotating brush on the bottom to clean the inside of the dishes, a top rack made of parallel bars to hold the dishes on the top while allowing the top brush to pass and reach the dishes, a bottom rack that rotates with the bottom brush, a mechanism to direct washing fluid and rinse fluid to appropriate chambers, and other supporting devices and mechanisms to facilitate the wash and rinse cycles.

Problems solved by technology

Due to various shapes of the dishes to be washed, and the proximity of the dishes to be washed, the fluid jets are oftentimes blocked so not to be able to reach the soiled dishes.

Even when a dish is washed with pressured fluid jets, it takes a long time to flush the grease and soil away from the dish.

As a consequence, it takes a long time to finish a wash cycle.

Another problem of the current spray system is that the wash cycle is not correlated with the quantities of the dishes to be washed.

Still another problem is that the current dishwashers require hot water, special detergents and, though not absolutely necessary, special rinse agents because of the way dishes are washed and rinsed.

Overall, the current system is inefficient and ineffective.

It consumes a large amount of energy and water.

And it imposes higher financial cost associated with special detergents and rinse agents.
