Disclosed herein is a dishwasher including a main body provided with an open hole and a washing tub; a door configured to open or close the open hole; a door opening/closing member configured to open or close the open hole; an air curtain disposed in the main body, to operate a fan such that ambient air is sucked and the sucked air is discharged; a detector configured to detect information of the fan; and a controller configured to diagnose the failure of the fan based on the detected information of the fan, to control an operation of the door opening/closing member such that the door is opened at a predetermined open time and an open time of the door is delayed when the fan is a failure state, and to control an operation of the fan when the fan is a normal state during a drying operation.

Disclosed is a household appliance comprising: a door; a door lock unit equipped with a hook part which is configured to unlock and open the door by moving outward; a motor configured to generate torque by using electricity; a driving gear unit which has a rotary shaft at one end portion and is configured to rotate by receiving the torque from the motor, wherein the one end portion pushes the hook unit to the outside of the door lock unit to open the door when the driving gear unit rotates in one direction; a sensing unit configured to sense the displacement of the other end portion of the driving gear unit when the hook unit moves to the inside of the door lock unit, wherein the other end portion rotates in the opposite direction about the rotary shaft of the driving gear unit; and a control unit configured to control the operation of the motor on the basis of the displacement, sensed by the sensing unit, of the other end of the driving gear unit.

A dish washer includes: a tub configured to receive an object to be washed and providing a washing space having an opening at a front side of the tub, a door configured to rotate relative to the tub between (i) a closing position that closes the opening of the washing space and (ii) a full opening position that exposes an entirety of the opening of the washing space, and a door position sensing part configured to sense a position of the door. The door position sensing part is configured to sense whether the door moves from the closing position and whether the door reaches a predetermined risk area start position set between the closing position and the full opening position.

A water-using household appliance includes an electrically controllable actuator, a first voltage source designed to provide a switch-on power amount to the actuator, a second voltage source designed to provide a holding power amount to the actuator, and a control unit designed to electrically connect the first voltage source to the actuator in order to switch on the actuator and, after a switch-on interval, to electrically disconnect the first voltage source from the actuator and to electrically connect the second voltage source to the actuator.

An automated door assembly for a dishwasher appliance includes a door frame pivotally mounted to the cabinet. An extension arm is mounted to and extends away from the door frame at approximately 90 degrees. A motor is mounted to the cabinet and is coupled to a distal end of the extension arm by a cable. The motor is selectively rotated to wind and unwind the cable to move the door frame between the closed position and the open position. A latch assembly engages a striker mounted on the door frame to initiate the opening and closing process.

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 light sensor device is disclosed for installation in a heat-using domestic electrical appliance such as, for example, a washing machine or a dishwasher and permits the implementation of a touch-free operating function, for example an automatic door opening function. The light sensor device includes in some embodiments: a window element which is formed of light-permeable material and is arranged with space on a first window side for hand movements; a first light source arrangement arranged to radiate visible light into the window element; a second light source arrangement which is arranged to radiate infrared light through the window element from a second window side opposite the first window side; and a photodetector arrangement which is sensitive to infrared light of the second light source arrangement and is arranged on the second window side, for detecting infrared light which strikes the photodetector arrangement from the window element.

A beverage container washing system may be used for rapid washing and/or sanitizing of beverage containers, e.g., for use in a retail environment to wash and/or sanitize customer-provided beverage containers prior to filling the beverage containers with purchased beverages, among other applications. The beverage container washing system may include multiple concentric housing members supported on a base, with each having one or more openings that may be selectively aligned through driven movement of at least one of the concentric housing members to provide access to a wash chamber.

A beverage container washing system may be used for rapid washing and/or sanitizing of beverage containers, e.g., for use in a retail environment to wash and/or sanitize customer-provided beverage containers prior to filling the beverage containers with purchased beverages, among other applications. The beverage container washing system may include multiple concentric housing members supported on a base, and an air knife chamber that supply air from a stationary air supply to an air knife opening on a rotatable one of the concentric housing members.

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.
