Abstract: A dishwasher is provided which uses a combined circulation/drain pump and an improved filtering system to enhance cleaning capability. The circulation section of the pump provides pressurization and supplies wash water to a spray arm of the dishwasher, while the drain section discharges the wash water. This single pump reduces space requirements, as well as manufacturing costs. A two stage filtration system may be used in the water collection area of the dishwasher to filter out unwanted material, and a third filter may further filter wash water prior to recirculation. Self cleansing mechanisms associated with each of the filters may be used to keep the filters free from obstructions and allow for the unobstructed flow and discharge of wash water.

Abstract: An apparatus for cleaning a squeeze roller of a liquid printer. The apparatus has general application for removing developer formed of a toner and a liquid carrier which adheres to an outer circumferential surface of the squeeze roller during lamination of the developer. The apparatus includes a blade holder and a blade having a plate of a predetermined rigidity. A cover member is coated on or adhering to the plate and has a lesser rigidity than the plate. One end of the blade is fixedly coupled to the blade holder and an opposite end thereof contacts the outer circumferential surface of the squeeze roller. The blade is disposed to be slanted in a trail counter direction to the rotational direction of the squeeze roller in a drip-line removing mode. Thus, the developer adhering to the squeeze roller can be cleaned.

Abstract: A washing machine includes an outer tub, an inner tub, fluid nozzle configured to spray fluid into the inner tub, a fluid pump, and a controller. The washing machine may also include a pulsator located in the inner tub for applying a force to clothing in inner tub. During a first washing cycle, the controller causes the inner tub to rotate, and the nozzle to spray fluid onto clothing in the inner tub. During the first washing cycle, a fluid level in the outer tub may be controlled so that it is lower than the inner tub. During a second washing cycle, the inner tub is held stationary, and the pulsator applies a force to clothing in the inner tub, as occurs in conventional washing machines. Because the fluid level in the washing machine can be kept quite low during the first washing cycle, less water and less detergent is required. Also, because the level of the water is kept below the rotating inner tub during the first washing cycle, less force and thus less energy are required to rotate the inner tub.
