A dishwasher having a tub at least partially defining a treating chamber, a liquid spray system, a liquid recirculation system fluidly coupling the treating chamber to the spray system to recirculate wash liquid from the treating chamber to the spray system, and filters capable of removing particles from the wash liquid. The filters include a microfilter fluidly coupled to at least one of the recirculation system and the spray system and an ultrafilter fluidly coupled to an outlet side of the microfilter.

An ozone sanitizing circulating water apparatus and method using a recirculating water pickup, pump, and water quality sensors for providing a water stream to a mixing venturi that is also connected to ozone generators to supply the water to a dispensing faucet. A capturing hood is flowably connected to a fan and an ozone neutralization system to capture and render inert any excess ozone generation. A fresh water valve, user inputs, operation indicators, and ozone generators are all connected to a control system for monitoring and control of the system to maintain safe and effective operation.

The disclosure provides for a drain system for an appliance. The drain system can include a Y-hose having a flexible end coupled to a supply of water from tub, a recirculating end, and a drain end, a recirculating valve coupled with the recirculating end, a drain valve spaced from the recirculating valve and coupled with the drain end, and wherein the recirculating end and the drain end are connected via a continuous connecting wall.

A dishwasher includes a tub at least partially defining a treating chamber, at least one dish rack in the treating chamber, and a rack height adjustment assembly. The rack height adjustment assembly includes an adjuster plate slidably coupled to the at least one dish rack and fixed vertically relative to the tub, the adjuster plate including at least one adjuster detent, a locking lever having a catch end that is biased to engage the adjuster detent to hold the dish rack in place in either a lowered or raised position, the locking lever being pivotally movable relative to the at least one dish rack between an engaging position where the catch end engages the adjuster detent and a release position where the catch end does not engage the adjuster detent and the dish rack is vertically movable between the lowered and raised positions, and an actuator configured to move the locking lever to the release position when the actuator is moved from an undepressed position to a depressed position.

A method for removing moisture from moist air in an appliance, such as a treating chamber of a dishwasher, wherein a drying system includes a condensing system and heat exchange systems that enhance condensation with both ambient air and cold water. Optionally, the method can also include a charge or charges of warm, ambient air or ambient air with moist air during recirculation of moist air.

The disclosure provides for a drain system for an appliance. The drain system can include a Y-hose having a flexible end coupled to a supply of water from tub, a recirculating end, and a drain end, a recirculating valve coupled with the recirculating end, a drain valve spaced from the recirculating valve and coupled with the drain end, and wherein the recirculating end and the drain end are connected via a continuous connecting wall.

Provided are a method performed by an appliance for washing and rinsing goods, where some of the goods loaded into the appliance are sensitive to process water temperature changes, and an appliance performing the method. The method may include receiving via a user interface, an instruction that an appliance, during execution of a general-type washing program, should take into account that goods sensitive to temperature changes are loaded into the appliance, measuring a temperature value in a washing compartment of the appliance upon executing a draining process, and supplying fresh water to the washing compartment of the appliance. The method may include measuring, when the fresh water has been supplied, whether the process water being accommodated in a sump of the appliance is at a target temperature value or not and if not adjusting the temperature of the process water in the sump to attain the target temperature value.

A dishwasher has a housing (10) with a wash chamber (20) and a top wall (204) with a non-planar surface (214;214) facing downwardly into the wash chamber, the surface having portions (216,218; 226,228) facing downwardly and facing in different horizontal directions (H1,H2; HX,HY,HP,HQ). Nozzles (402) mounted within the wash chamber spray a liquid upwardly within the wash chamber. The surface portions redistribute the upwardly-sprayed water in horizontal directions to provide a more uniform washing action. A portable dishwasher may have a fresh water reservoir (422) and a used water reservoir (430) mounted in the housing beneath the wash chamber. The used water reservoir may be removably mounted in the housing so that the user can remove used wash water by removing the used water reservoir. The portable dishwasher can be used at a location remote from a sink.

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.

Provided is a method of operating a dishwasher including a heat pump circuit, wherein a condensate collection container is associated with an evaporator of the heat pump circuit. The method may include the steps of pumping a washing liquid from a sump of the dishwasher using a pump device, opening a first valve in a condensate conduit connecting the condensate collection container with a suction conduit of the pump device, pumping a condensate from the condensate collection container using the pump device. A dishwasher may also be provided.
