Abstract

An improved water powered dishwasher uniquely adapted to be operated by a domestic water supply line of either high, low or medium pressure including a housing, a rack rotatably mounted within the housing, the rack being adapted to support articles to be washed and a water jet subassembly for directing jets of water in the direction of the rack to impart rotational movement thereto. The jet subassembly comprises a collimated jet for emitting a collimated stream of water in the direction of the lower periphery of the rack for initiating and assisting in sustaining the rotation thereof and a second spray jet for washing the articles and for urging forward rotation of the rack. The second spray jet includes a generally vertically extending spray conduit disposed proximate the periphery of the rack. This spray conduit can be controllably rotated about its vertical axis to precisely control the speed of rotation of the rack.

Dependent claims

A dishwasher adapted to be interconnected with a source of water under pressure, comprising:

(a) a base;
(b) a closure housing carried by said base, said closure housing having interconnected top and side walls;
(c) a rack having upper and lower peripheral portions interconnected upstanding portions adapted to support articles to be washed;
(d) rack suspension means for supporting said rack for rotation within said housing including a rigid generally vertically extending column;
(e) jeet means interconnected with the source of water under pressure for directing jets of water in the direction of said rack to impart rotational movement thereto, said jet means comprising:
(1) a spray jet means for urging rotation of said rack, said spray jet means comprising a first conduit extending beneath said rack, a second generally vertically extending conduit interconnected with said first conduit and disposed proximate the periphery of said rack and a third conduit connected to said second conduit, said second conduit being rotatable about the vertical axis thereof to control the speed of rotation of said rack and said third conduit being fixedly positioned relative to said closure housing so as to extend over said vertically extending column;
(2) a collimated jet means for emitting a collimated stream of water in the direction of said rack;
and
(3) control means comprising:
(i) valve means for regulating the flow of water from the source of water under pressure to said jet means;
and
(ii) diverter means for selectively diverting the flow of water between said collimated jet means and said spray jet means, said diverter means being adjustable to direct said collimated stream of water in a first direction urging counter lockwise rotation of said rack and in a second direction urging clockwise rotation of said rack and being further adjustable to divert all of the flow of water to said spray jet means.
