A dishwasher for treating dishes according to at least one cycle of operation and having a tub at least partially defining a treating chamber and defining an access opening, a sprayer providing a spray of liquid into the treating chamber, a liquid recirculation system defining a recirculation flow path for recirculating the sprayed liquid from the treating chamber to the sprayer, and an air supply system having a conduit configured to function as an overflow conduit.

A dishwashing appliance may include a cabinet, a tub, a pump, a spray assembly, a fluid recirculation duct, a cold water loop, a heat exchanger, and a tub fan. The fluid recirculation duct may extend from a path inlet to a path outlet to recirculate air within a wash chamber. The cold water loop may define a cold water nozzle disposed within the fluid recirculation duct to provide a condensing, cold-water flow into the fluid recirculation duct between the path inlet and the path outlet. The heat exchanger may be mounted to the cold water loop outside of the fluid recirculation duct to cool water within the cold water loop. The tub fan may be configured to selectively motivate an airflow from the path inlet to the path outlet.

The present invention relates to a dishwasher, a method for controlling the operation of the dishwasher, and a program therefor. To this end, a dishwasher according to one embodiment of the present invention may comprise: a tub having a washing space therein and open on the front; a door which opens and closes the open front of the tub; a drying air supply unit including a blowing motor, a blowing fan, a heater, and a temperature sensor; and a processor controlling the operation of the dishwasher. The processor can control the ON/OFF of the heater so that the temperature of the heater is maintained within a first threshold range when the time during which the dishwasher enters and operates in a door open drying process is less than a predetermined time. Accordingly, the present invention can efficiently dry dishes by controlling the operation of the heater so that the temperature of the heater is maintained within a certain range.

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.

An adjustment device, an air duct structure, an exhaust system, a dishwasher, and a method for controlling the dishwasher are provided. The adjustment device is applied in an exhaust system. The exhaust system has an exhaust channel with a second air inlet and a first air inlet. The adjustment device includes an adjustment mechanism and a controller. The adjustment mechanism is configured to, under control of the controller, respectively adjust a flow rate of a first gas entering the exhaust channel through the first air inlet and a flow rate of a second gas entering the exhaust channel through the second air inlet, to control a ratio of the first gas entering the exhaust channel to the second gas entering the exhaust channel. Humidity of the second gas is lower than humidity of the first gas.

A positive and negative pressure system and an operation method therefor, and a positive and negative pressure electrical appliance using the positive and negative pressure system. The positive and negative pressure electrical appliance comprises: a positive and negative pressure refrigerator, a positive and negative pressure washing machine, a vacuum dishwasher/fruit and vegetable cleaning machine, a super-oxygenated water washing range hood, a positive and negative pressure oven/fryer/microwave oven, a positive and negative pressure fresh-keeping compartment, a positive and negative pressure fresh-keeping warehouse, and a positive and negative pressure modular cabinet. Regulating airflow with positive and negative pressure, or carrying multiple effective loads such as ozone, an air catalyst, a negative ion, modified atmosphere gas and water for orderly getting in and out of or staying in a positive and negative pressure chamber, and exerting the required effects on objects therein.

A dishwasher includes a body including an opening through which an object to be washed is loaded, a door to be connected with one side of the body and while the door is connected to the one side of the body, the door selectively opens and closes the body, a driving device that drives the door to be selectively opened on the body, a memory to store at least one instruction, and at least one processor configured to execute the at least one instruction, and control the driving device such that the door is opened in relation to a drying cycle, wherein the at least one processor is configured to obtain an operation state of a heating device around the dishwasher, and based on opening of the door being necessary, adjust a time point of opening the door in relation to the drying cycle based on the obtained operation state.

A water bearing appliance, control method, and system are provided. Operating data from appliances are transmitted to a receiver over a network such as the Internet. Maintenance, cleaning, and repairs are initiated based on the operating data, and can be triggered remotely and automatically. A machine learning model(s) is trained according to operating conditions of various appliances and respective outcomes, such as maintenance, repairs, damages, life expectancy, and/or the like, to learn correlations therebetween. A digital twin appliance data object is generated for an appliance and applied to the machine learning model(s) to provide a predictive maintenance data object. Cleaning regimens, maintenance, repairs, and/or the like are configured to particular operating circumstances of an appliance.

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 and a mixing fan that draws ambient air from the surrounding environment of the dishwasher to lower a dew point of the air that is exhausted by the dishwasher. In some instances, an additional inlet fan may be used to direct ambient air into the wash tub, and in some instances, the ambient air drawing into the mixing conduit by the mixing fan may be untreated.

A dishwasher including a tub forming a washing chamber; a drying device disposed outside of the tub and including an inlet through which air from the washing chamber is introduceable, a flow channel in which air from the washing chamber introduced through the inlet flows, a fan that is operable to cause air from the washing chamber to be introduced through the inlet to flow in the flow channel, a heater in the flow channel to heat air in the flow channel, an outlet through which air in the flow channel is discharged to the washing chamber, and a temperature sensor between the heater and the outlet; and at least one processor configured to operate the fan based on a start of a drying cycle and to determine an initial operation time point of the heater during the drying cycle based on temperature detected by the temperature sensor.
