A dishwasher includes a tub forming a washing chamber and a blowing unit that blows air into the tub, where the blowing unit includes a housing having a discharge port, a blowing fan disposed inside the housing, and a valve disposed between the blowing fan and the discharge port to prevent moisture from being introduced into the blowing fan, and the valve is rotated from a closed position to an open position by blowing of the blowing fan and return to the closed position again by an own weight thereof.

A door mechanism, for example for a domestic dishwasher, is disclosed, wherein the door mechanism includes a door latch for holding a door of the dishwasher closed in a closed position, and an electrically controllable door opener for the mechanized partial opening and subsequent closing of the door. The door opener includes coupling members, which can be brought into push- and pull-transmitting but releasable coupling engagement with one another, on the door and on an appliance main body of the dishwasher on which the door is movably mounted. The coupling members, when in coupling engagement, allow forces to be transmitted between the door and the appliance main body in a force transmission path which runs past the door latch. The pull strength of the coupling engagement of the coupling members can be variable in dependence on the position of the door.

A dishwasher includes a housing having walls defining a tub having an outlet for humid air to flow out from the tub, an inlet for dry air to flow into the tub, and a door for closing the tub to an exterior environment, and a drying system contacting 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 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 dishwasher includes a housing having walls defining a tub with an outlet for humid air to flow out from the tub and an inlet for dry air to flow into the tub. The dishwasher also includes a drying system with a fluidized bed containing an adsorbent material, and an air circuit for supplying air to fluidize the adsorbent material via an air inlet, with at least a portion of the air inlet in contact with at least one wall of the tub such that heat is transferred from the tub to the air. During a regeneration cycle, the air circuit supplies heated ambient air to the fluidized bed to regenerate the adsorbent material. During an adsorption cycle, the air circuit receives hot humid air from the tub to be dried by the adsorbent material through the fluidized bed and returned as dry air to the tub.

An automatic dishwasher with a treating chamber, at least one dish holder, and a sprayer. The sprayer can be coupled to the dish holder and include a set of fan spray nozzles or a set of jet nozzles. The set of fan spray nozzles or the set of jet nozzles fluidly connect the sprayer and treating chamber. One or more angles in which fluid flows from the set of fan spray nozzles or the set of jet nozzles into the treating chamber can be adjusted.

A dishwasher includes a tub with an outlet for humid air to flow out from the tub, and an inlet for dry air to flow into the tub; and a drying system with an air circuit and an adsorbent component disposed between an air inlet and an air outlet in the air circuit. The adsorbent component includes a water harvesting nanomaterial for absorbing water from the humid air and releasing water upon regeneration. During a drying cycle, the air circuit draws humid air from the tub such that the adsorbent component absorbs moisture from the humid air to form a dry air stream, and during a subsequent wash cycle, the air circuit is blocked from receiving air flow such that latent heat can be transferred to the adsorbent component via conduction, convection, or both, to regenerate the water harvesting nanomaterial.

A dryer includes a dehumidification filter containing a temperature responsive material with an upper critical solution temperature, a fan sending gas through the dehumidification filter, a heater heating the dehumidification filter, and a controller controlling the fan and the heater and switching an operation mode of the fan and the heater between a drying mode and a regeneration mode, wherein, in the drying mode, an object to be dried is dried with the fan sending the gas through the dehumidification filter that is heated by the heater to temperature higher than or equal to the upper critical solution temperature, and in the regeneration mode, the dehumidification filter is regenerated with the fan sending the gas through the dehumidification filter at temperature lower than the upper critical solution temperature.

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 prevents an airflow guide from clattering effectively without an additional member and supports the airflow guide reliably. A lower end surface of a fastening nut is exposed to a wash space. The dishwasher prevents wash water from remaining between the fastening nut and a tub, and prevents the tub and a dry air supply hole from corroding.
