A dishwasher includes a housing having walls defining a tub having an outlet and inlet for humid air to flow out from and into the tub, respectively. A drying system contacts at least one wall of the tub. The drying system includes an inlet conduit fluidly connected to the outlet and an outlet conduit fluidly connected to the inlet with the inlet conduit and the outlet conduit forming an inverted V-shaped air circuit defining an airflow path therethrough. The drying system also includes at least one adsorbent component having an adsorbent material positioned along the airflow path, and at least one gate check valve blocking airflow from the tub to the adsorbent material during a wash cycle. The adsorbent material is regenerated via heat transfer through the at least one wall from the tub during a wash cycle when the gate check valve is closed.

A tubular spray element for a dishwasher is rotatably supported and/or supplied with fluid at an intermediate location along the length of the tubular spray element, such that least one aperture that directs fluid into a wash tub is disposed on each side of the intermediate location. In addition, a tubular spray element drive may be positioned externally from the wash tub and mechanically coupled to the tubular spray element through a shaft seal such that the fluid supply to the tubular spray element can be entirely within the wash tub.

A dishwasher system for cleaning dishes may include a dishwasher tub configured to house dishes therein and run a dishwasher cycle, a door assembly configured to selectively seal the dishwasher tub, the door assembly including an inlet nozzle arranged on the inside of the door assembly, the inlet nozzle extending across the width of the door at the top of the door assembly to receive hot and moist air post wash from the dishwasher tub, and a duct fluidly connected to the inlet nozzle and configured to transfer the air through the door assembly and out an outlet nozzle during a drying phase of the dishwasher cycle prior to the door assembly being opened post-cycle.

A distribution cap is configured to couple to a nozzle of a dish washer and to guide air from the nozzle to be discharged in a discharge direction. The distribution cap includes a fitting pipe configured to couple to the nozzle, a first bypass pipe that is connected to the fitting pipe and extends in a direction different from the discharge direction, where the first bypass pipe is configured to be positioned above the nozzle based on the fitting pipe being coupled to the nozzle, and a second bypass pipe that extends from an end portion of the first bypass pipe in the discharge direction, where the second bypass pipe defines a discharge opening at an end portion thereof.

A cap is configured to couple to a nozzle of a dish washer that is configured to supply air into a tub of the dish washer. The cap includes a lower cap configured to couple to an upper end portion of the nozzle, a flow cover configured to cover a part of the upper end portion of the nozzle, and an upper cap coupled to the lower cap and configured to, based on the cap being coupled to the nozzle, be spaced apart from and positioned above the nozzle and the flow cover. The cap defines a discharge opening configured to discharge air supplied to an inner space of the cap through the nozzle.

A dishwasher includes a tub, a door, and a drying device configured to supply air to a washing space in the tub. The drying device includes a condensing duct disposed outside the tub, a cold air supply module that is disposed outside the tub and defines a heat exchange flow path part adjoining the condensing duct, and a fan configured to cause air flow in the condensing duct. The condensing duct includes an upstream portion communicating with the inlet port and extending above the inlet port and then downward, and a heat exchange portion connected to the upstream portion and extending downward to the heat exchange flow path part. A height of an upper end of the heat exchange flow path part is equal to or larger than a height of a lower end of the inlet port.

A dishwasher includes a tub, a door, and a drying device configured to supply air to a washing space in the tub. The drying device includes a drying duct that is disposed outside the tub and includes a condensing duct and a return duct, a fan configured to cause a flow of air in the drying duct, and a heater configured to heat the air in the drying duct. The condensing duct includes a first condensing duct connected to an inlet port configured to receive moist air from the washing space, and a second condensing duct disposed vertically below a bottom portion of the tub and connected to the first condensing duct. The return duct includes a return upstream end connected to the second condensing duct and a return downstream end connected to an outlet port configured to supply air to the tub.

A dishwasher includes a tub, a door, and a drying device disposed outside the tub. The drying device includes a condensing duct that faces an outer surface of the tub, that is in fluid communication with an inlet port defined at the tub, and that extends in a vertical direction and a first direction intersecting the vertical direction, and a fan configured to cause a flow of air in the condensing duct. The condensing duct includes an upstream portion in fluid communication with the inlet port, a downstream portion that is in fluid communication with the upstream portion and includes a bent portion disposed below the upstream portion, and a rib that is disposed inside the bent portion and extends across the bent portion, where the rib protrudes in a second direction that intersects the vertical direction and the first direction.

A method includes supplying, using a water supply coupled to a tub of a dishwasher, water into the tub, wherein the tub includes a sump and a sprayer; circulating, using a circulation circuit coupled to the sump and the sprayer, the water from a sump to the sprayer; storing, using a water tank coupled to the circulation circuit, the circulated water from the circulation circuit on completion of a first phase; drawing heat, using a supply side of a thermoelectric module system coupled to the circulation circuit and the water tank, from the stored water in the water tank from the first phase; and outputting, using an output side of the thermoelectric module system, heat to the circulated water in the circulation circuit for a second phase.

A dishwasher includes a tub at least partially defining a treating chamber, with an access opening. The dishwasher further includes a closure movable between closed and opened positions to selectively close and open the access opening. A method of drying dishes within the dishwasher includes moving the closure to a partially open position between the closed and opened positions.
