A domestic appliance includes: an appliance housing which provides an appliance compartment and has a loading opening for access to the appliance compartment; an appliance door mounted so as to be rotatable about a pivot axis for closing the loading opening; a motor unit in operative connection with the appliance door and by which the appliance door is transferrable from an open position to a closed position closing the loading opening; and a clutch device arranged between the motor unit and the appliance door and in operative connection with the motor unit on a drive side thereof and with the appliance door on a driven side thereof. The clutch device has a clutch that is switchable and transferrable from a disengaged position to an engaged position and vice versa, the clutch causing an automatic switching from the disengaged position to the engaged position during operation of the motor unit.

A latch module incorporated with an automatic opening function and a secure lock function includes a latch, a spring that applies a force to move the latch in a first direction, a drive to move the latch in a second direction, a cam that transmits power of the drive to the latch, and first and second switches that are turned on and off by the cam. The first and second switches are in a first mode in which the two switches are turned on and the latch is disposed at a manual lock position, a second mode in which the first switch is turned on and the second switch is turned off and the latch is disposed at an opening position, a third mode in which the first switch is turned off and the second switch is turned on and the latch is in a secure lock position.

A household dishwasher includes a dishwasher cavity, a door attached pivotably to the dishwasher cavity, a door opening and closing device for automated opening and closing of the door, and a control unit designed to actuate the door opening and closing device. The control unit is designed to detect a motor current of a drive element of the door opening and closing device and to evaluate the detected motor current as to whether the door opening and closing device is functional or non-functional.

A dishwasher includes an additional function module that is disposed at and fixed to a front upper frame reinforcing the upper side of an open front surface of a tub, without a fixing frame exclusive for the function module, thereby ensuring a simple structure and a reduction in manufacturing costs. A mutual coupling structure is formed between the front upper frame and a front side frame reinforcing the sides of the open front surface of the tub, to readily determine the positions of the front upper frame and the front side frame, thereby ensuring a simple manufacturing process.

A dishwashing appliance may include a cabinet, a tub, a spray assembly, a circulation pump, a pressure sensor, and a controller. The circulation pump may be in fluid communication with a wash chamber defined by the tub. The pressure sensor may be upstream of the circulation pump. The controller may be configured to initiate a washing operation including activating the circulation pump, detecting movement of the door from a closed position, detecting return of the door to the closed position, calculating a modified time period for flood detection, determining pressure at the pressure sensor exceeds a pressure threshold following detecting return of the door to the closed position, initiating the modified time period in response to determining pressure at the pressure sensor exceeds the pressure threshold, and directing the circulation pump based on measuring the elevated pressure and expiration of the modified time period.

The present invention relates to a lock mechanism that enables the door of the machine to be closed smoothly by the user and the machine can be refunctioned again without any problems, even though the lock latch is in the off position, and is generally designed to be used in all white appliances such as dishwashers and similar machines with doors that require a locking system in home, dining hall, restaurant, hotel, and similar areas of usage.

Disclosed is a home appliance comprising: a door; a door lock part which includes a hook portion configured to unlock and open the door when moving outward; a motor which is configured to generate rotational force by using electricity; a gear part which is configured to receive the rotational force from the motor and rotate by the rotational force; and a driving gear part which includes a toothed portion formed to be engaged with the gear part, is configured to receive the rotational force from the gear part by the toothed portion and rotate by the rotational force, and is configured to push the hook portion out of the door lock part to open the door when rotating in one direction.

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 dishwashing appliance may include a cabinet, a door, and a sensor assembly. The door may extend along the lateral direction between a first lateral edge and a second lateral edge. The door may be rotatably mounted to the cabinet to move about a rotation axis between an open position and a closed position. The sensor assembly may detect a rotational position of the door and include a stationary electrical contact and a movable electrical contact. The stationary electrical contact may be mounted on the cabinet at a first side or a second side. The movable electrical contact may be mounted on the door at the first lateral edge or the second lateral edge. The movable electrical contact may be in selective alignment and electrical connection with the stationary electrical contact based on the rotational position of the door.

Adoor latch includes a gripper adjustable between a gripping state and a release state, which gripper, in the gripping state, is able to grip a closing member for holding the door closed which moves relatively closer to the gripper in a closing direction as a door of the domestic appliance is closed, and, in the release state, frees the closing member for opening the door, wherein, when the door is closed, the gripping state of the gripper is released by a relative releasing movement of the closing member carried out in the closing direction; and an electrically controllable displacement mechanism for displacing the gripper, under electrical control, from a retracted position into an advanced position against a restoring spring force, which advanced position, when the closing member is gripped, corresponds to a state in which the door is closed to a lesser degree than in the retracted position.
