The present disclosure relates to a dishwasher. The dishwasher of the present disclosure includes a tub forming a washing chamber washing a washing target, a first circulation duct in which an air discharged from the tub flows, an outside air inflow duct in which an air from the outside flows, a fan assembly discharging the air thereto, passes through the first circulation duct and the outside air inflow duct, a second circulation duct heating and supplying a part of the air discharged from the fan assembly to the tub, an exhaust duct discharging a remaining part of the air discharged from the fan assembly to the outside.

A dishwasher includes: a cabinet defining an external appearance of the dishwasher; a tub disposed in the cabinet to form a space where to wash dishes; a heat exchanger disposed between the tub and the cabinet to form a space in which external air flows; and a condensing module disposed between the heat exchanger and the cabinet and configured to exchange heat of air discharged from the tub with the external air flowing in the heat exchanger such that the heat-exchanged air flows into the tub.

A dishwashing appliance, as provided herein, may include a cabinet, a tub, a water tank, a wet air duct, a dry air duct, a water supply conduit, a diverter valve, and a diverted branch. The tub may be housed within the cabinet and may define a wash chamber. The water tank may be mounted within the cabinet outside of the wash chamber. The wet air duct may extend from the wash chamber to the water tank. The dry air duct may extend from the water tank to the wash chamber. The water supply conduit may extend to the wash chamber. The diverter valve may be disposed along the water supply conduit upstream from the wash chamber. The diverted branch may extend from the diverter valve to the water tank to selectively guide water from the water supply conduit to the water tank.

A warewash machine includes a housing defining a ware inlet, a ware outlet and an internal chamber including a plurality of sequential spray zones including at least one wash zone and a rinse zone downstream of the wash zone in a ware conveyance direction. A vent path leads from the chamber leading to a vent outlet for connecting to a building ventilation system. A damper is provided for controlling a flow area at a location along the vent path. A controller is connected to control a position of the damper, the controller configured to adjust a position of the damper based upon input from at least a first temperature sensor, wherein the first temperature sensor is located at one of (i) the ware inlet, (ii) the ware outlet or (iii) along the vent path. Methods of operating a warewash machine are also provided.

A conveyor type ware washing machine uses a heat pump to reduce exhaust heat and to heat incoming water. A modulating valve is used to control incoming water flow through a heat exchanger of the heat pump. Processing circuitry automatically dynamically adjusts the modulating valve between a plurality of open states based on the sensed refrigerant head pressure of the heat pump, so that the refrigerant head pressure is maintained in a predefined range. The ware washing machine is efficient, and reduces the amount of heat exhausted to ambient. Related methods are also disclosed.

An apparatus for removing moisture as liquid from moisture-laden air in an appliance is provided. The apparatus includes a body that defines a channel extending from a first position to a second position and a serpentine flow path between the first position and the second position that operates to redirect the moisture-laden air to remove the liquid from the moisture-laden air. The body includes an opening at the serpentine flow path that is closed when the apparatus is secured to the wall of the appliance. In operation, the body cooperates with the wall to cause the moisture-laden air entering the channel at the first position through an inlet opening in the wall to pass into the serpentine flow path to remove the liquid from the moisture-laden air before the liquid exits the channel at the second position through an outlet opening in the wall.

A dishwasher appliance includes a tub that defines a wash chamber. A door is mounted to the tub for selectively accessing the wash chamber of the tub. A vortex air dryer has four vents and a fan. The four vents are positioned and oriented for forming a vortex air flow in the wash chamber during operation of the fan.

A device for the dehumidification of air in a processing space of a dishwasher is connected in an air-conducting manner to the processing space of the electric appliance. The device includes carbon-based fibres, which are designed as a fibre unit. The fibre unit is arranged between the processing space or an air duct connected thereto and at least one dehumidification chamber of the device. The carbon-based fibres absorb moisture from the air of the processing space, which they then release again in the dehumidification chamber. During this process, the carbon-based fibres are moved backwards and forwards between the processing space or air duct and the dehumidification chamber, preferably by slow rotation on a support.

A dishwasher includes a wash container for cleaning dishes, glasses, flatware or similar items to be washed during a program sequence which includes a drying phase or another process phase. The wash container has an inlet opening for inflow of a volume flow of air. The volume flow of air entering the wash container through the inlet opening varies a number of times over the drying phase or the other process phase.
