Provided are a dish washing machine and a controlling method thereof. When water is sprayed from a nozzle while a vane is positioned at a reference position during a drainage operation, since a deflection angle of the vane is bent back and the water is sprayed toward a rear wall of a washing tub, the water forms a fast and strong water current over a bottom plate of the washing tub to remove garbage which remains at a filter while flowing over the bottom of the washing tub. Accumulation at a filter at a top end of a sump and that may block the filter during washing such as preliminary washing, main washing, etc., is washed, thereby eliminating the inconvenience of having to separate and wash the filter, and effectively improves performance by avoiding poor circulation of water that may occur due to a filter blockage or generation of bubbles.

A dishwasher for treating dishes according to at least one cycle of operation and methods for operating a dishwasher. The dishwasher may have a tub at least partially defining a treating chamber, a rotatable sprayer, a drive system operably coupled to the rotatable sprayer to effect movement of the rotatable sprayer, and a liquid recirculation system for recirculating sprayed liquid. The dishwasher may have a sump including a sensor enclosure, a first sensor element located within the sensor enclosure and configured to sense at least a portion of the rotatable sprayer, and a controller configured to receive output from the first sensor element and control the drive system and the liquid recirculation system to rotate the rotatable sprayer while selectively supplying liquid to the rotatable sprayer.

A household dishwasher includes a washware receptacle, a holding facility positioned in or on the washware receptacle to hold washware, an actively driven spray arm, and an open-loop and closed-loop control facility designed to influence a rotational movement of the spray arm as a function of a position of the holding facility in or on the washware receptacle so that the spray arm pauses close to the holding facility to apply wash liquor and/or fresh water to the washware held by the holding facility.

A dishwasher includes a tub at least partially defining a treating chamber, a rotatable spray arm comprising an outlet, and a liquid supply conduit fluidly coupled to the spray arm. A pump can be fluidly coupled to the liquid supply conduit and operated to flow liquid through an aperture in the liquid supply conduit and through the outlet in the rotatable spray arm.

The present disclosure discloses a sequential dishwasher, and relates to the technical field of sequential dishwashers and automatic cleaning methods. The sequential dishwasher includes a casing to the bottom of which a drainage pipe is connected, a dish cleaning mechanism, arranged in the casing; a rotary drive mechanism, arranged below the dish cleaning mechanism; a liquid supply mechanism, arranged in the casing and used for providing a detergent or tap water for cleaning of two sides of a dish in a spraying manner; and a control system, configured to control and connect the dish cleaning mechanism, the rotary drive mechanism, and the liquid supply mechanism for a clamping drive, a rotary drive, and a liquid supply cleaning drive during dish cleaning. The present disclosure further provides an automatic cleaning method for dishes. The present disclosure may effectively save detergent consumption and water consumption of cleaning while realizing rapid cleaning of the single dish, and when facing cleaning of a small number of dishes, may complete the automatic cleaning of the dishes more efficiently with more energy saved.

A dishwasher having a tub at least partially defining a treating chamber and in which is provided a rotating sprayer for emitting liquid into the treating chamber. The rotation of the spray arm may be controlled such that rotation of the spray arm is responsive to a determination that the spray arm has contacted an obstacle within the treating chamber.

A water-conducting domestic appliance includes a washing container, a door which is pivotably mounted to the washing container to define with the washing container a washing chamber for washing items, and a door opening module configured to automatically open the door. A detector detects a presence of a living being in a defined area in front of the domestic appliance. In the event the presence of a living being has been detected by the detector in the defined area, a control device prevents the door opening module from automatically opening the door.

Provided is a dishwashing machine determining whether a nozzle spraying washing water is clogged, and a method for controlling the same. In according to one aspect, the dishwashing machine may include a main body; a washing tub provided in the main body; a basket provided in the washing tub for accommodating dishes; a plurality of fixed nozzles fixedly arranged in a first direction of the washing tub and spraying washing water in a second direction; a vane provided for deflecting washing water sprayed from the fixed nozzles towards dishes accommodated in the basket, the vane being linearly reciprocated in the second direction; and a controller determining whether the vane is linearly reciprocated in the second direction in parallel with the first direction.

A dishwasher appliance includes a spray detection sensor and a variable speed pump. Based upon signals from the spray detection sensor, a speed of the variable speed pump is changed. By changing the speed of the variable speed pump, a trajectory of wash fluid from a spray assembly of the dishwasher appliance is also changed such that the wash fluid is directed towards a detergent dispenser of the dishwasher appliance. A related method for operating a dishwasher appliance is also provided.

A method of controlling the filling with water of a household appliance after treatment including activating a wash pump to a first speed, opening a load valve and starting a time counter, closing the valve and stopping the counter, calculating a flow-rate, opening and closing the valve again based on the calculated flow-rate.
