Abstract
A method and dishwasher utilize one or more tubular spray elements that are both rotatable about longitudinal axes thereof and discretely directable by one or more tubular spray element drives between a plurality of rotational positions about the longitudinal axes thereof. Thus, through the provision of discretely directable tubular spray elements, fluid such as wash fluid and/or pressurized air may be focused in a wash tub, in many cases providing more efficient resource usage in the dishwasher.
Claims34
A dishwasher, comprising:
- a wash tub including a plurality of walls;
- a fluid supply configured to supply fluid to the wash tub;
- a port on a first wall among the plurality of walls of the wash tub and in fluid communication with the fluid supply;
- a tubular spray element disposed in the wash tub and extending substantially perpendicular from the first wall, the tubular spray element being rotatable about a longitudinal axis thereof and including one or more apertures extending through an exterior surface thereof, and the tubular spray element in fluid communication with the fluid supply through the port on the first wall to direct fluid from the fluid supply into the wash tub through the one or more apertures;
- and
- a tubular spray element drive coupled to the tubular spray element and configured to discretely focus the tubular spray element to each of a plurality of controlled rotational positions about the longitudinal axis of the tubular spray element.
A dishwasher, comprising:
- a wash tub including a plurality of walls;
- a rack mounted in the wash tub;
- a fluid supply configured to supply fluid to the wash tub;
- a port on a first wall among the plurality of walls of the wash tub and in fluid communication with the fluid supply;
- a tubular spray element disposed in the wash tub and extending substantially perpendicular from the first wall in a cantilevered fashion and proximate the rack, the tubular spray element being rotatable about a longitudinal axis thereof and including one or more apertures extending through an exterior surface thereof, and the tubular spray element in fluid communication with the fluid supply through the port on the first wall to direct fluid from the fluid supply into the wash tub through the one or more apertures;
- and
- a tubular spray element drive including an electric motor coupled to the wash tub, the tubular spray element drive further coupled to the tubular spray element and configured to rotate the tubular spray element to each of a plurality of rotational positions about the longitudinal axis of the tubular spray element.
A dishwasher, comprising:
- a wash tub including a plurality of walls;
- one or more racks mounted in the wash tub;
- a fluid supply configured to supply fluid to the wash tub;
- two or more tubular spray elements disposed in the wash tub and extending substantially perpendicular from the first wall proximate the one or more racks, each of the two or more tubular spray elements being rotatable about a longitudinal axis thereof and including one or more apertures extending through an exterior surface thereof, and each of the two or more tubular spray elements in fluid communication with the fluid supply to direct fluid from the fluid supply into the wash tub through the one or more apertures thereof;
- and
- a tubular spray element drive including an electric motor coupled to the wash tub, the tubular spray element drive further coupled to each of the two or more tubular spray elements and configured to rotate all of the two or more tubular spray elements about the longitudinal axes thereof.
