US 4,368,747 A · Dishwasher

Abstract

A compact, portable, self-contained dishwasher adapted to be operably connected to a domestic hot water supply. The unit requires no auxillary power, relying solely upon water pressure for operation. The dishes and cookware to be washed are positioned upon a rotatable rack mounted within an upstanding housing. Water jets are directed at the rack to cause rotation thereof and to effectively accomplish the washing action. The water jets comprise a first collimated water jet adapted to initiate rotation of the rack and a second uniquely configured spray jet system adapted to sustain its action. A control valve is provided to control the flow of water through the collimated jet thereby enabling precise regulation of the speed of rotation of the rack. Also forming a part of the apparatus is a metering system for controllably mixing liquid soap or detergent with the water flowing into the jets.

Dependent claims

A rotatable dishwasher, comprising:

(a) a housing;
(b) a rack rotatably mounted within said housing, said rack being adapted to support articles to be washed;
(c) jet means for directing a jet of water in the direction of said rack to impart rotational movement thereto, said jet means comprising:
(i) a first collimated jet means for emitting a collimated stream of water in the direction of said rack for initiating rotation of said rack;
and
(ii) a second non-rotatable spray jet means for sustaining rotation of said rack;
and
(iii) control means for controllably and simultaneously regulating the flow of water between said first collimated jet means and said second spray jet means whereby the force of the stream of water directed at said rack can be controllably decreased after rotation of said rack is initiated while the force of the water eminating from said spray jet means is correspondingly increased thereby sustaining uniform rotation of said rack;
(d) dosing means adapted to cooperate with said second spray jet means for dosing with soap water flowing through said second spray jet means.

A rotatable dishwasher, comprising:

(a) a housing having a floor, a roof and a side wall providing an access opening therein;
(b) closure means for closing the access opening;
(c) a rack rotatably mounted within said housing, said rack being adapted to support articles to be washed and being provided with a plurality of spaced apart downwardly depending vanes;
(d) jet means for directing a jet of water in the direction of said rack to impart rotational movement thereto, said jet means comprising:
(i) a first collimated jet means for emitting a collimated stream of water in the direction of said vanes of said rack for initiating rotation of said rack;
(ii) a second spray jet means for sustaining rotation of said rack;
and
(iii) control means for simultaneously adjusting said first collimated jet means and said second spray jet means to regulate the pressure of the water emitted therefrom, whereby the force of the water emitted from said first means can be increased or decreased while at the same time the force of the water emitted from said second means is correspondingly increased or decreased whereby the speed of rotation of said rack can be controlled;
and
(e) a dosing means adapted to cooperate with said second spray jet means for dosing with soap water flowing through said second spray jet means.

7 more elements

A dishwasher adapted to be operated by interconnection with a domestic hot water supply, said dishwasher comprising:

(a) a generally cylindrically shaped housing;
(b) a rack rotatably mounted within said housing, said rack having a circular shaped floor and a plurality of support members adapted to support articles to be washed and including a plurality of circumferentially spaced apart vanes depending downwardly from said floor;
(c) a hollow housing having first and second water outlet ports and an inlet port interconnected with said supply of domestic hot water;
(d) a first collimated jet means operably connected with said first water outlet port of said hollow housing for directing a collimated stream of water at said vanes for imparting first rotational forces to said rack;
(e) a second spray jet means operably connected with said second water outlet port of said hollow housing for directing a plurality of fine jets of water at said articles carried by said rack for imparting second rotational forces to said rack, said second spray jet means comprising a non-rotatable conduit having a substantially vertically extending leg disposed proximate the periphery of said rack and a substantially horizontally extending leg disposed above said rack, said conduit being provided with a multiplicity of apertures located and arranged so that a multiplicity of fine jets of water will be simultaneously directed at said articles supported on said rack to sustain rotational movement of said rack;
and
(f) control means operably associated with said first water outlet port of said hollow housing for regulating the flow of water through said first port toward said first collimated jet means, whereby said first rotational forces imparted by said first jet means can be decreased while at the same time the flow of water through said second port is correspondingly increased thereby increasing said second rotational forces imparted by said second spray jet means.
