A dish treating appliance can include a tub at least partially defining a treating chamber and having an access opening providing access to the treating chamber, a closure selectively closing the access opening, a condenser comprising an inlet, an outlet, and a condensing passage defining a serpentine path with multiple turns fluidly coupling the inlet and the outlet, with the inlet fluidly coupled to the treating chamber, the outlet fluidly coupled to ambient air, and multiple ambient air inlets provided in the serpentine path, and a blower fluidly coupled to the condenser flowing a volume of air through the serpentine path of the condenser, and at least one separator wall located within the condenser.

A dish treating appliance for treating dishes according to a cycle of operation can include a tub defining a treating chamber. The treating chamber can fluidly couple to condenser having an inlet, an outlet, and a condensing passage. The condenser can further include multiple ambient air inlets to mix humid air drawn from the treating chamber with ambient air within the condenser. The condenser can further integrate a water inlet with a condenser outlet, such that a water supply and condensed liquid can be provided to the treating chamber through the same opening.

A method is provided for operating a dishwasher (1) in the form of a batch dishwasher, which has a treatment chamber (2) for accommodating washware to be cleaned. Provision is made, during an adsorption phase, for air to be conducted out of the treatment chamber (2) through a sorption unit (41), which contains a reversibly dehydratable dry material, in such a way that the dry material absorbs moisture from the air stream, wherein the air is then returned to the treatment chamber (2). Provision is further made, during a desorption phase, for the dry material of the sorption unit (41) to be heated in such a way that moisture is desorbed from the dry material as steam. During the desorption phase, the sorption unit (41) is subjected to forced ventilation only to such an extent that recondensation of desorbed steam in the sorption unit (41) itself is effectively prevented.

A dishwasher with a tub that defines a treatment chamber, a sump fluidly connected to the tub, sprayers within the treatment chamber, a drain pump fluidly connecting the sump to a discharge pipe, a water tank fluidly connected to the sump with a controllable valve, a softener, and a diverter valve fluidly connecting the sump and the sprayers.

Disclosed a controlling method of a dishwasher comprising a water supply step for supplying wash water, a preliminary washing step for injecting the wash water to one or more dishes, a main washing step for injecting the wash water mixed with washing liquid to the dishes, a rinsing step for injecting the wash water to the dishes, and a heating step for heating the wash water in one or more of the preliminary washing step, the main washing step and he rinsing step, wherein a heater sensing step for determining an operational state of a heater heating the wash water is performed in the heating step in a state where the circulation of wash water is stopped.

The present invention relates to a dishwasher configured to perform a separate storage mode and a single drying course including only a single drying step by using a sorption drying device to meet a user's need to perform only an step of quickly drying dishes and the user's need to store dishes in a clean state for a long period of time, thereby significantly improving user convenience.

A dishwasher includes a drying system that incorporates a mixing conduit that mixes air streams from an exhaust fan that draws humid air from a wash tub, an inlet fan that supplies ambient air to the wash tub, and a gate device that is movable within a range of positions to regulate fluid flow through at least one of first and second inlets of the mixing conduit. A controller may perform a multi-stage drying operation that, in a first stage, controls the gate device while the inlet fan is deactivated, and in a second stage, additionally controls the speed of the inlet fan while controlling the gate device.
