Disclosed is a dishwasher that sprays washing water and steam to wash dishes or cooking appliances. The dishwasher according to the present invention includes: a tub which receives a target of washing; a sump which is disposed at a bottom of the tub to store washing water; a spray arm which sprays the washing water stored in the sump into the tub; a heater which generates heat by heating washing water in a circulation passage connecting the sump and the spray arm; and a steam passage which is connected to the steam nozzle, and in which the steam generated by the heater flows. Accordingly, the steam generated in the circulation passage may be supplied smoothly.

A method of cleaning a washing machine and components and systems for enabling a user to clean the washing machine are provided. The method includes gaining access to debris that is trapped in otherwise inaccessible and/or concealed areas and/or directing debris out of inaccessible and/or concealed areas. The components include a jet channel that selectively couples to a discharge manifold in use and is removable to provide access to an interior area of the discharge manifold for cleaning. The systems include a removable mount assembly for accessories and a purging system for pumps and other concealed areas. The purging system is configured to discharge purging fluid through a plurality of purging ports and into concealed areas so as to direct debris in the concealed areas out of the concealed areas.

A fluid flow structure for a washing machine is located within a wash tank of the washing machine, which includes a fluid flow guide surface, and a support for the guide surface. The guide surface includes at least one region contoured inconsistently from the contour of at least one corresponding wall of the washing machine wash tank. The contour of the guide surface is generally curved so as to aide in reducing and/or preventing the pinning of items that often occurs in rectangular wash tanks of the prior art. The support for the guide surface creates a gap between the guide surface and at least one wall of the washing machine wash tank.

The present invention relates to a dishwasher. The dishwasher according to the present invention includes a tub for providing a washing space, a rack for accommodating dishes in the tub, a spray nozzle for spraying wash water toward the dishes accommodated in the rack, a sump for supplying the wash water to the spray nozzle, a pump for pumping the wash water stored in the sump to the spray nozzle, a supply pipe connecting the sump and the spray nozzle, and an air jet generator disposed in a supply flow path formed by the supply pipe to suck outside air to the wash water flowing along the supply pipe and crush the air to thereby form air bubbles.

A washing machine and/or a fluid flow structure for a washing machine wash tank is provided. The wash tank is generally rectangular and includes a bottom wall, two side walls and two end walls extending upwardly from said bottom wall. The wash tank further includes at least one flow directional opening in at least one of the walls. In a preferred embodiment, the wash tank includes a plurality of flow directional openings positioned along one of the side walls of the wash tank. A fluid flow structure is located within said wash tank, which includes a fluid flow guide surface, and a support for said guide surface. The guide surface includes an expansion structure that is designed to counteract expansion of the guide surface that occurs during operation of the washing machine. In one embodiment the expansion structure is an expansion slot that engages a portion of the guide surface. As the guide surface expands the expansion slot is pressed against the portion of the guide surface, causing the expansion slot to expand into a relief area associated with the expansion slot at a location generally opposite of the portion of the guide surface.
