A dish rack is slidingly mounted to the rail assemblies for movement in and out of the treating chamber relative to the access opening.

A dishwasher having a treating chamber with one or more sprayers through which liquid is recirculated into the treating chamber, whereby the impact of the spray emitted from the sprayers impacts the structure forming the treating chamber to generate noise. Damping material is applied to structure forming the treating chamber to reduce the sound level of the impact exterior of the dishwasher.

A dishwasher with a tub that at least partially defines a treating chamber with an access opening, a closure moveable relative to the tub to selectively open and close the access opening, a lower dish holder located within the treating chamber, a middle dish holder located within the treating chamber above the lower dish holder, and an upper dish holder located within the treating chamber above the middle dish holder and having container supports defining a support surface.

A dishwasher includes a main body, a tub provided in the inside of the main body, a basket provided in the inside of the tub to store dishes, an injection unit configured to spray wash water to wash dishes in the basket, and a circulation pump configured to circulate wash water, a sump arranged on a lower surface of the tub, and a connector provided to connect the circulation pump to the injection unit and having a tubular shape. The sump includes a coupling portion extending upward from the lower surface of the tub, and the connector and the injection unit are connected to each other in the inside of the tub by being coupled to the coupling portion.

Disclosed is a dishwasher comprising a tub defining a washing space, a sump provided to collect the wash water injected into the tub, a supply pump provided to supply the wash water stored in the sump to the tub, a filter provided in the sump and comprising a first body having a plurality of first holes formed along a lateral circumferential surface; and a second body arranged in a radially inner side of the first body and having a plurality of second holes formed along a lateral circumferential surface, wherein the second body comprises an external wall portion in which the second holes are formed and an internal wall portion positioned in a radially inner side of the external wall and vertically extended.

An automatic dishwashing device may include a tub defining a hollow dishwashing cavity having a back, top, bottom, and two sides and is accessible via an access opening at a front of the cavity, a rack slidably disposed within the tub and moveable in a longitudinal direction between a stored position within the tub to an extended position where the rack extends outside of the tub, and a tray slidably engaged with the rack for sliding movement in the longitudinal direction, wherein the tray is configured to selectively remain partially within the tub when the rack is in the extended position or extend outside the tub when the rack is in the extended position.

A system for dispensing a detergent solution from a solid detergent into a dishwasher includes a dispenser that can collect water sprayed into the dishwasher and use the collected water to produce the detergent solution by dissolving a portion of the solid detergent, controlling the amount of the detergent solution produced, and releasing the produced detergent solution between cleaning cycles.
