A method, system, and computer-program product for preventing overfilling in a dishwasher are disclosed herein. According to one embodiment, a method for preventing overfilling in a dishwasher is provided, wherein the dishwasher includes a water valve for providing water to the dishwasher and a drain pump for removing water from the dishwasher. The method comprises detecting an overfill condition in the dishwasher with at least one detection device, wherein the overfill condition corresponds to a water level in the dishwasher that is greater than a predetermined threshold. The method further includes controlling the drain pump and the water valve in response to detecting the overfill condition in order to facilitate removal of the overfill condition.

A dishwasher including a washing chamber to wash dishes, a sump concavely formed at a lower portion of the washing chamber to collect water used in washing, a microfilter disposed at the sump to filter out dirt produced when the dishes are washed, and an ultrasonic generator to radiate ultrasonic waves toward the microfilter. Since the microfilter is automatically cleaned by the ultrasonic generator, a user may not need to manually clean the microfilter.

In a method for pumping a fluid out of an aquiferous household device such as a dishwashing machine, a drain pump and a circulation pump are operated at least partially simultaneously to ensure that, in the event of an abrupt stop of the circulation pump, reverse flow that may cause filter cake formed by separating soiling and particles to loosen resulting in their re-soiling of the items to be cleaned. The speed of the circulation pump is lowered from a maximum speed to at least a minimum speed substantially without pressure surges before startup of the drain pump.

A dishwasher includes a tub at least partially defining a treating chamber and a sprayer for spraying liquid to the treating chamber. The sprayer may include a liquid passage provided in the interior of the body, at least one upper outlet extending through the upper surface of the body and in fluid communication with the liquid passage, at least one lower outlet extending through the lower surface of the body and in fluid communication with the liquid passage, and a valve body moveable relative to the body to fluidly couple the at least one upper outlet and the at least one lower outlet to the liquid passage.

A method of operating a dishwasher having a wash tub and a reuse tank for storing liquid for subsequent reuse, wherein the condition of the water in the reuse tank may be monitored and/or acted upon to limit the likelihood of undesired effects associated with the growth of micro-organisms in the liquid.

The present invention relates to a home appliance, in particular a dishwasher, a washing machine or the like, and a method for controlling said home appliance. The home appliance comprises a water supply unit including a water supply port configured to be connected to a water supply for supplying water, like fresh water, to the home appliance, a water reservoir for storing water to be supplied to the home appliance by the water supply unit, a treatment space for treating objects in the home appliance, like dishes or laundry, a heat exchanger for exchanging heat between the water supplied to the reservoir and the water discharged from the treatment space by at least one pump unit, a control unit for controlling the operation of the home appliance and a bypass device for bypassing water supplied by the water supply unit past the reservoir to the treatment space.

A method, system, and computer-program product for preventing overfilling in a dishwasher are disclosed herein. According to one embodiment, a method for preventing overfilling in a dishwasher is provided, wherein the dishwasher includes a water valve for providing water to the dishwasher and a drain pump for removing water from the dishwasher. The method comprises detecting an overfill condition in the dishwasher with at least one detection device, wherein the overfill condition corresponds to a water level in the dishwasher that is greater than a predetermined threshold. The method further includes controlling the drain pump and the water valve in response to detecting the overfill condition in order to facilitate removal of the overfill condition.

A dishwasher includes a tub at least partially defining a treating chamber and a sprayer for spraying liquid to the treating chamber. The sprayer may include a liquid passage provided in the interior of the body, at least one upper outlet extending through the upper surface of the body and in fluid communication with the liquid passage, at least one lower outlet extending through the lower surface of the body and in fluid communication with the liquid passage, and a valve body moveable relative to the body to fluidly couple the at least one upper outlet and the at least one lower outlet to the liquid passage.

A dishwasher according to an embodiment of the disclosure may include: a cabinet; a tub disposed in the cabinet; a sump disposed below the tub; a deionizer comprising at least one electrode configured to produce soft water using raw water supplied from a water source, and supply the soft water to the sump; a plurality of flow paths including at least one pipe and/or at least one hose configured to allow the raw water, the soft water, and used water collected in the sump to flow; a plurality of valves disposed in each of the plurality of flow paths; and a controller including at least one processor, comprising processing circuitry, individually and/or collectively, configured to control the plurality of valves to allow the deionizer to be regenerated using the raw water or the used water, in at least one of a washing process or a rinsing process.

Disclosed in the present invention are an energy-saving dishwasher and a control method therefor. The inner container is arranged inside the housing, the inner container is internally provided with a manifold type dish rack for placing dishes and spraying steam to perform steam cleaning on the dishes, and the manifold type dish rack is placed on a supporting frame fixed to the inner container. A water storage tank, a steam/hot water integrated generating device and a water pump are arranged below the inner container, and the steam/hot water integrated generating device includes a generating assembly and a control assembly. The manifold type dish rack is configured to place the dishes and simultaneously sprays steam to clean the dishes. The steam/hot water integrated generating device is configured to generate steam and hot water, heating is performed to generate the steam, and then relative cooling is performed to generate the hot water.
