An automatic dishwasher having first and second sprayers located within a washtub, a diverter valve to selectively divert liquid flowing from the wash chamber between the first and second sprayers, and a drive system moving the first sprayer in the wash chamber.

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 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.

A household appliance includes a circulation pump for circulating dishwashing liquid in a washing compartment of the household appliance. A drain pump empties the dishwashing liquid from the washing compartment. For the purposes of ventilating the drain pump, a control device is provided to activate the drain pump after the washing compartment has been filled with the dishwashing liquid and before or during operation of the circulation pump.

An adjustment device, an air duct structure, an exhaust system, a dishwasher, and a method for controlling the dishwasher are provided. The adjustment device is applied in an exhaust system. The exhaust system has an exhaust channel with a second air inlet and a first air inlet. The adjustment device includes an adjustment mechanism and a controller. The adjustment mechanism is configured to, under control of the controller, respectively adjust a flow rate of a first gas entering the exhaust channel through the first air inlet and a flow rate of a second gas entering the exhaust channel through the second air inlet, to control a ratio of the first gas entering the exhaust channel to the second gas entering the exhaust channel. Humidity of the second gas is lower than humidity of the first gas.

A dishwasher includes: a tub, a water storage chamber provided under the tub and configured to store water from inside the tub, a filter disposed in the water storage chamber and configured to filter water flowing into the water storage chamber, a drain pump configured to discharge the water accommodated in the water storage chamber to the outside, and a controller including at least one processor, comprising processing circuitry. The controller may be configured to control the drain pump to discharge the water accommodated in the water storage chamber to the outside based on the lapse of a specified soaking time after completion of a water supply operation or a jet operation.

The invention provides a dishwasher with a residue disposal device, comprising a housing and a liner, the liner is arranged in the housing, a spray assembly and a water collection assembly are arranged in the liner, the spray assembly is connected to the water collection assembly, the water collection assembly is provided with a drain hose, a residue disposal device is arranged on the drain hose and connected to the water collection assembly by means of a return pipe, and a three valve is arranged at a joint of the return pipe and the drain hose. The requirement for disposing residues in sewage in a water cup can be met, that is, a closed water path from the water collection assembly to the residue disposal device, the drain hose and the water collection assembly is formed, and under the action of a negative pressure generated by the residue disposal device arranged on the closed water path, water flows unidirectionally to wash the water cup, thus reducing the quantity of residues in the water cup. The requirement for discharging residues can be met, that is, the residue disposal device can replace a drain pump to form a discharge water path from the water collection assembly to the residue disposal device and the drain hose to promote processed food residues to be discharged from the drain hose. The whole process is implemented automatically without manual intervention.
