Abstract
An improved rotatable dishwasher adapted to be connected to a domestic water supply line including a housing, a rack rotatably mounted within the housing, the rack being adapted to support articles to be washed, a water jet subassembly including a control mechanism for directing a jet of water in the direction of the rack to impart rotational movement thereto, the jet subassembly comprising a first collimated jet for emitting a collimated stream of water in the direction of the rack for initiating rotation thereof and a second spray jet for sustaining rotation of the rack, and safety valving interposed between the unit and the domestic water supply for positively preventing any flow of fluid from the dishwasher in a direction toward the domestic water supply line.
Claims12
A dishwasher, comprising:
- (a) a base;
- (b) a closure housing carried by said base;
- (c) a rack rotatably mounted within said housing, said rack being adapted to support articles to be washed;
- (d) jet means for directing a jet of water in the direction of said rack to impart rotational movement thereto, said jet means comprising:
- (1) 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
- (2) a second spray jet means for sustaining rotation of said rack;
- said means comprising a first conduit extending beneath said rack, a second generally vertically extending conduit and a third conduit interconnected with said second conduit and extending above said rack, said second and third conduits being angularly adjustable relative to said rack;
- (3) control means for controllably and simultaneously regulating the flow of water between said first collmated jet means and said second spray jet means whereby a stream of water can be directed at said rack with sufficient velocity to initiate rotation thereof;
- and
- (e) drain means carried by said base and extending externally of said housing for draining water from the interior of said housing to the exterior thereof.

- (a) a base;
- (b) a closure housing carried by said base;
- (c) a rack rotatably mounted within said housing, said rack being adapted to support articles to be washed;
- (d) jet means for directing a jet of water in the direction of said rack to impart rotational movement thereto, said jet means comprising:
- (1) 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
- (2) a second spray jet means for sustaining rotation of said rack;
- said means comprising a first conduit extending beneath said rack, a second generally vertically extending conduit and a third conduit interconnected with said second conduit and extending above said rack, said second and third conduits being angularly adjustable relative to said rack;
- (3) generally cylindrically shaped valve housing carried by said base externally of said closure housing, said valve housing having:
- (i) a water inlet;
- (ii) a first water outlet connected to said spray jet means;
- (iii) a second water outlet connected to said collimated jet means;
- and
- (iv) an internal valve seat disposed between said water inlet and said second water outlet;
- (4) control means for controllably and simultaneously regulating the flow of water between said first collimated jet means and said second spray jet means whereby a stream of water can be directed at said rack with sufficient velocity to initiate rotation thereof, said control means comprising a valve assemblage carried within said valve housing, said valve assemblage comprising:
- (i) a valve stem having upper and lower extremities, said valve stem being movable from a first position to a second position and including a tapered surface located intermediate its extremities, said tapered surface being adapted to sealably engage said internal valve seat when said valve stem is in a first position;
- and
- (ii) biasing means for yieldably urging against movement of said valve stem from a first to a second position.

A dishwasher adapted to be operably interconnected with a source of water under pressure, comprising:
- (a) a base;
- (b) a closure housing carried by said base said closure housing comprising a first fixed portion mounted on said base and a second movable portion carried by said base and rotatable with respect to said first portion;
- (c) releasable locking means for locking said second portion of said closure housing against rotation;
- (d) a rack rotatably mounted within said housing, said rack being adapted to support articles to be washed;
- and
- (e) jet means for directing a jet of water in the direction of said rack to impart rotational movement thereto, said jet means comprising:
- (1) 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
- (2) a second spray jet means for sustaining rotation of said rack;
- said means comprising a first conduit extending beneath said rack, a second generally vertically extending conduit and a third conduit interconnected with said second conduit and extending above said rack, said second and third conduits being angularly adjustable relative to said rack;
- (3) a generally cylindrically shaped valve housing carried by said base externally of said closure housing, said valve housing having:
- (i) a water inlet;
- (ii) a first water outlet connected to said spray jet means;
- (iii) a second water outlet connected to said collimated jet means;
- and
- (iv) an internal valve seat disposed between said water inlet and said second water outlet;
- (4) control means for controllably and simultaneously regulating the flow of water between said first collimated jet means and said second spray jet means whereby a stream of water can be directed at said rack with sufficient velocity to initiate rotation thereof, said control means comprising a valve assemblage carried within said valve housing, said valve assemblage comprising:
- (i) a valve stem having upper and lower extremities, said valve stem being movable from a first position to a second position and including a tapered surface located intermediate its extremities, said tapered surface being adapted to sealably engage said internal valve seat when said valve stem is in a first position;
- and
- (ii) biasing means for yieldably urging against movement of said valve stem from a first to a second position;
- (f) flow control safety means for permitting flow of water under pressure in a first direction from said source of water toward said water inlet of said valve housing, but preventing flow of water in an opposite direction;
- and
- (g) drain means carried by said base and extending externally of said housing for draining water from the interior of said housing to the exterior thereof.
