Dishwasher with reversible rotating spray agitator
First Claim
Patent Images
1. A dishwasher comprising at least one spray agitator adapted for rotating about a substantially vertical axis (2) and adapted for being fed with water under pressure to emit several water jets;
- and a hydraulic pressure device for alternately reversing a direction of rotation of the agitator, characterized by the fact that said hydraulic device comprises a hollow rotor (8) that is journalled on the agitator (1) and having an axis of rotation (7) offset with respect to the axis of rotation (2) of the agitator;
at least one pressure nozzle (9) disposed on the rotor and adapted for emitting a water jet (10) that rotates around the axis of rotation (7) of the rotor; and
a tube (6;
60) that emerges from the agitator (1);
said tube having the rotor journalled thereon and provided with at least one activating nozzle (13;
130) adapted for emitting a water jet (12) directed against several inclined blades (11) located on the rotor (8) in such a way as to make the rotor rotate in a single direction.

Abstract
A dishwasher has a spray agitator (1) rotating about an axis (2) and fed with water under pressure so as to emit several water jets. A rotating pressure jet (10) periodically reverses the direction of rotation of the agitator (1). The dishes are washed efficiently even if a mechanical obstruction interferes with the agitator (1).
