A dish washer includes a cabinet, a tub positioned inside the cabinet, a sump provided in a lower portion of the tub, a case brake provided on a side wall of the tub connected to the sump, and a filter device positioned below the tub inside the cabinet, to selectively filter or unfilter water received from a water supply source, and to supply the filtered water or the unfiltered water to the case brake, the water passed through the case brake is collected in the sump, the case brake is located higher than the sump to prevent a backflow of the water collected in the sump to the case brake.

The present disclosure relates to a dishwasher having a heat pump, including a dishwasher body provided with a tub configured with a washing space therein and a sump provided at a bottom of the tub to temporarily accommodate washing water; a heat pump having a compressor, an evaporator, an expansion apparatus, and a sump condenser provided inside the sump to exchange heat with washing water inside the sump; and a controller that controls the heat pump to be driven so as to increase the temperature of the washing water inside the sump. As a result, a heating time of washing water may be shortened, thereby suppressing washing time from being prolonged.

Provided is a structure of a sump assembly of a dishwasher. The dishwasher includes a tub forming a washing chamber, and a sump assembly provided at a lower side of the washing chamber and configured to store washing water in the washing chamber, wherein the sump assembly includes a sump housing having a water storage chamber storing the washing water and a sidewall portion forming the water storage chamber, and a heater provided on the sidewall portion to apply heat to the washing water stored in the sump assembly. The heater includes a planar heating element, and the planar heating element provided in a cylindrical shape forms the sidewall portion.

A filter device for a water-bearing domestic appliance which has a surface filter with a sleeve shape, a support structure for said surface filter and a flow-through filter housing with filter inlet and filter outlet. The surface filter is held stably on the support structure, which has through-flow openings and a central opening at the end. A first flow path for water leads into the support structure and out again through the through-flow openings and the surface filter. A second flow path leads into the support structure and out again only through the central opening. The support structure is designed circumferential and is formed by support ribs which between them comprise the through-flow openings. The surface filter is attached or pressed onto the outside of the support structure in such a way that it covers the through-flow openings and rests on the outside of the support ribs.

A dishwasher comprises a tub that defines a wash space configured to accommodate one or more objects to be washed, a sump that is configured to store wash water, a water supply pump that supplies the wash water to the tub, a base that is disposed below the tub, and provides a space to accommodate the sump and the water supply pump, an air supply device that is configured to supply air to the tub, a first filter that is disposed at the base and in fluid communication with the tub and the air supply device, a second filter that is disposed at the base and in fluid communication with the tub, and a water supply that is connected to the second filter and configured to supply the wash water.

Disclosed are a dishwasher that sprays wash water to wash dishes or cookware and a method of controlling the same. The method of controlling the dishwasher includes supplying wash water from an external water source to a sump and intermittently driving a washing pump to change the level of water around a filter, thereby removing filth from the filter.

A filtering system (10) includes a casing (12) internally defining a cavity (14) and has an inlet (16) configured to receive a fluid and leading into the cavity (14), and an outlet (18) configured to deliver the fluid coming from the cavity (14). A filtering assembly (100) is contained in the cavity (14) and is configured to be crossed by the fluid entering the casing (12) through the inlet (16), so as to trap any solid particles, in particular microplastic ones, contained in the fluid. A compacting assembly (200) situated in the cavity (14) is configured for collecting and compacting the solid particles trapped by the filtering assembly (100). A driving assembly (300) is configured to drive the compacting assembly (200).

A dishwashing appliance with a filtration assembly capable of removing/shredding/pulverizing large dishwashing debris from recirculated dishwashing fluid is provided. The dishwashing appliance may include a tub, a spray system, a recirculation pump, a drainage pump, and a grinding type filtration assembly in fluid communication with the spray system, the recirculation pump, and the drainage pump.
