Water powered dishwasher
First Claim
1. A soap dispenser for a water powered dishwasher, suitable for dispensing soap from storage to be mixed uniformly with water passing through a water inlet, the dishwasher having a container shell and top defining a washing and rinsing cavity therebetween a water inlet extending from one side of the container shell below the bottom of the shell, to the centre thereof into a washing cavity, a water inlet and a water outlet, and rotatable spray means adapted to rotate about the water inlet extending into the cavity, said soap dispenser comprising a soap storage in open communication with the atmosphere through at least a downwardly directed aperture, through which soap is discharged, an upwardly directed opening in the top of the water inlet disposed directly below the downwardly directed aperture for receiving the discharged soap and means in the water inlet when water is passing through the inlet, to cause a continuous suction on the soap discharged from said storage and assist to draw the soap through the opening into the water inlet to be mixed with the water passing therethrough.

- 1. A soap dispenser for a water powered dishwasher, suitable for dispensing soap from storage to be mixed uniformly with water passing through a water inlet, the dishwasher having a container shell and top defining a washing and rinsing cavity therebetween a water inlet extending from one side of the container shell below the bottom of the shell, to the centre thereof into a washing cavity, a water inlet and a water outlet, and rotatable spray means adapted to rotate about the water inlet extending into the cavity, said soap dispenser comprising a soap storage in open communication with the atmosphere through at least a downwardly directed aperture, through which soap is discharged, an upwardly directed opening in the top of the water inlet disposed directly below the downwardly directed aperture for receiving the discharged soap and means in the water inlet when water is passing through the inlet, to cause a continuous suction on the soap discharged from said storage and assist to draw the soap through the opening into the water inlet to be mixed with the water passing therethrough.

5. A water powered dishwasher, comprising a container shell, a top adapted to seat on said container shell to define therebetween a washing and rinsing cavity, a water inlet and a water outlet, a soap storage having an aperture in the bottom thereof in communication with the atmosphere for the downward discharge of soap therethrough, said water inlet extending from its mouth proximate one side of the container shell, below the bottom of the shell to the center thereof and into the cavity secured in substantially vertical relation to said bottom at all times, said water inlet having a cylindrical tubular first portion of predetermined diameter extending longitudinally from its mouth a predetermined distance to a restricted tubular portion of predetermined length secured thereto to receive all water passing through said first portion, said restricted portion of lesser outer diameter than the internal diameter of said first portion, a second tubular portion of greater outer diameter than said first portion but of substantially the same internal diameter as the outer diameter of said first portion to be secured to said first portion at the end thereof remote said mouth, said second portion having an upwardly directed opening therein when secured to said first portion, said restricted portion being such as to extend from said first portion, below the opening in said second portion when said second portion is secured to said first portion to the side of the opening remote the mouth of the water inlet, the portion of said water inlet within the cavity having a first aperture disposed proximate its upper end to discharge a column of water substantially perpendicular to the bottom of said container shell, and at least one second aperture of lesser cross-sectional area than the water column, disposed in said water inlet means below said first aperture;
- rotatable spray means secured for rotation about the inlet means, said rotatable spray means have a lower tube disposed substantially parallel to the bottom of said container shell and in communication with said at least one second aperture to receive a flow of water therfrom;
said lower tube having apertures diposed in the wall of said tube to effect outflow of jets of water therefrom, each jet having horizontal and vertical force components;
said rotatable spray means further comprising a perpendicularly disposed tube relative to said container shell bottom and in communication with said first aperture to receive said column of water and to discharge the water through apertures in the wall of said tube as jets of water, each jet having at least a horizontal force component. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
- rotatable spray means secured for rotation about the inlet means, said rotatable spray means have a lower tube disposed substantially parallel to the bottom of said container shell and in communication with said at least one second aperture to receive a flow of water therfrom;
- 16. For use in a water powered dishwasher having a container shell and top defining a washing and rinsing cavity therebetween, a water inlet and a water outlet and rotatable spray means, an improved soap dispenser comprising a soap storage having a generally downwardly directed discharge aperture disposed above a portion of the inlet intermediate the mouth of the inlet and the washing cavity and means in the water inlet to act on the soap discharged from said soap storage by suction to draw the soap into the water inlet to be mixed with the water, said means having a second tubular portion extending below the soap storage having an upwardly directed opening disposed directly below the discharge aperture in the storage, and secured at either end thereof, first and third equal diameter tubular portions of lesser outer diameter than the outer diameter of said second portion but of substantially the same outer diameter as the internal diameter of said second portion, and a fourth tubular portion of lesser outer diameter than the internal diameter of said first or third portions, attached at one end to said first portion and secured thereto to receive all water passing therethrough, said fourth portion extending through said second portion and terminating proximate the juncture of said second and third portions whereby soap drawn into said opening by gravity and suction, mixes with water at the juncture of said second and third tubular portions.
