A dishwasher door assembly can include a door with an exterior surface bounding an interior space, a controller, a light source electronically coupled to the controller and positioned within the interior space, and an optical waveguide coupled to the door and configured to direct emitted light from the light source out of the interior space.

A dish washer includes: a washing tank including a sump at a bottom surface thereof; a water storage unit disposed inside or outside the washing tank to store washing water to be supplied to the washing tank; a heat pump system including a compressor that compresses and circulates refrigerant, a first heat exchanger disposed in the sump, an expansion apparatus, and a second heat exchanger disposed in the water storage unit to heat washing water for washing the dishes; and a reverse valve that changes a flow of refrigerant flowing through each of the first heat exchanger and the second heat exchanger to allow each of the first heat exchanger and the second heat exchanger to be switched from each other between a heating mode for heating the washing water and a heat recovery mode for recovering heat from washing water discharged to the outside from the washing tank.

Proposed is a home appliance that includes a cabinet defining an exterior of the home appliance; a reception space defined inside the cabinet and configured to receive objects in 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.

Proposed is a home appliance in which a reception space defined in the home appliance can be seen from the outside without opening a door through a viewing window. In the home appliance, the viewing window is mounted to the door, and when a user knocks on the door, a knock input by the user is detected and the inside of the reception space is illuminated such that the inside of the reception space can be seen from the outside through the viewing window. Accordingly, a user can see the inside of the reception space by a simple motion without opening the door.

An appliance, as provided herein, can include a direct current load and a current sensing circuit that can be coupled to the direct current load. The current sensing circuit can be configured to collect electrical data corresponding to the direct current load. The appliance can include one or more processors that can be coupled to the current sensing circuit. The one or more processors can be configured to identify at least one attribute of the direct current load based, at least in part, on the electrical data and activate at least one operation of the direct current load or the appliance based, at least in part, on identification of the at least one attribute of the direct current load.

A dishwasher comprises an image sensor, first and second drawers, first and second actuators configured to respectively extend or retract the first and second drawers, and a computer system. The computer system is configured to receive images from the image sensor, determine whether an object is within a threshold distance, and in response to determining that an object is moved to within the threshold distance, use a washwear recognition system to determine whether the object comprises an washwear item. A determined washwear type and a washwear dimension are used to identify an unoccupied location in of a size and configured suitable to receive the washwear item. In response to identifying an unoccupied location of a size and configured suitable to receive the washwear item, an actuator among the first actuator and the second actuator is caused to extend a corresponding drawer to thereby receive the item of dishware.

A method includes receiving, at an artificial intelligence (AI) accelerator of a computing system, image data of one or more objects from an image sensor and performing an AI operation on the image data at the AI accelerator of the computing system using an AI model. The method further includes determining a custom cleaning cycle at the AI accelerator in response to performing the AI operation.

A device for drying and polishing items such as glasses and cutlery, the device including an enclosure having apertures through which an end of the items can be inserted; a plurality of movable cleaning elements within the enclosure for drying and/or polishing the items; and a selectively operable steam distribution system for applying steam within the enclosure to at least one of the cleaning elements and/or the items, whereby the cleaning elements dry or polish the items, wherein the steam distribution system is operable on insertion of an end of said items into the enclosure.

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 and a terminal device which creates a washing course to serve a purpose of use based on a user input and provides at least an expected amount of power to be supplied and an expected amount of water to be supplied for the created washing course. The terminal device includes a display for displaying an operating condition of a default washing course of the dishwasher; an input for receiving a command to change the operating condition from a user; and a controller for controlling the display to display at least one of an expected amount of power to be supplied, an expected amount of water to be supplied, and an expected time, which is changed according to a user-set washing course in response to the command received to change the operating condition of the default washing course.
