A dishwasher includes a tub that accommodates dishes; a nozzle assembly that sprays washing water; a vane assembly that is moved between a first position and a second position of an inside of the tub and changes a progression path of the washing water so that the sprayed washing water can be directed toward the dishes; and a controller that moves the vane assembly to the second position if the vane assembly is disposed at the first position. When a linear washing portion washes a small quantity of dishes by spraying washing water while making a reciprocal motion in part of an inside of a washing chamber, a washing time can be reduced, and concentrated washing can also be performed.

A dishwasher includes a regeneration heater and a washing water heater that are controlled to operate simultaneously so that an operation period of the regeneration heater and an operation period of the washing water heater at least partially overlap each other, thereby heating the washing water and regenerating a moisture absorbent effectively and in a short time even in a washing course with a short washing cycle time.

A dishwasher with a tub at least partially defining a treating chamber, a liquid spraying system, a liquid recirculation system defining a recirculation flow path, and a liquid filtering system. The liquid filtering system includes a rotatable filter disposed in the recirculation flow path to filter the liquid and a diverter overlying and spaced from at least a portion of the upstream surface to form a gap there between.

The present invention relates to a dishwasher comprising a body; a heat pump that is disposed inside the body and that has a first heat exchanger providing the heating of the water to be used in the washing step, a second heat exchanger transferring the heat received from the first heat exchanger to the wash water and a compressor fluidly connected to the first heat exchanger and the second heat exchanger, realizing the refrigerant cycle; a water collection tank that is disposed just under the first heat exchanger, wherein the water condensing on the first heat exchanger is collected, and a water softening unit that enables the water taken from the mains to be softened so as to be used in the washing step.

A method of operating a dish treating appliance includes a user interface disposed along the top edge of a door for selectively opening and closing access to a treating chamber. The user interface can be illuminated and operating the user interface can include operating a user input mode when the door is open and a status mode when the door is closed.

A free-standing Energy Recovery System enables sanitary recovery of thermal energy with heat transfer from hot waste effluent to incoming domestic water. The source of the effluent may, for example, be conventional commercial ware-washing, clothes washing equipment, pasteurization and other industrial processes.

The user interface can be illuminated and operating the user interface can include operating a user input mode when the door is open and a status mode when the door is closed.

A dishwasher door assembly can include a door with an exterior surface bounding an interior space, a controller with a controller switch that is inaccessible from the exterior of the door and actuatable by movement in a first direction, and an actuator, accessible from the exterior of the door, and moveable in a second direction different from the first direction, such that movement of the actuator in the second direction actuates the controller switch in the first direction.

Proposed is a home appliance that includes a reception space configured to receive objects therein; a heater configured to heat the reception space; a door configured to open/close an open surface of the reception space, the door having a viewing window provided at the door; a lamp configured to illuminate an inside of the reception space; a sensor assembly configured to output a knock-on signal based on detecting a user's knock; and a controller configured to turn on/off the lamp based on the knock-on signal output by the sensor assembly, wherein based on a present state of the home appliance corresponding to at least any one of a plurality of preset exceptional situations, the controller is configured to not turn on/off the lamp regardless of the knock-on signal being output.
