A dishwasher for treating dishes according to at least one automatic cycle of operation and including a tub having a bottom wall for at least partially defining a treating chamber in which dishes may be received for treatment, at least one sprayer provided on the bottom wall, and having at least one opening through which liquid is emitted into the treating chamber, and a recirculation circuit fluidly coupling the treating chamber to the at least one sprayer such that liquid emitted into the treating chamber may be directed back to the sprayer for recirculation.

A liquid filtration system includes a sump screen, a filter, and a cap. The sump screen mounts to a tub bottom wall and includes a plate and a filter aperture edge mounted through the plate. The plate includes a sump mesh having a sump mesh size of less than approximately 0.1 inches. The filter mounts to the filter aperture edge and includes a sidewall and a plurality of posts mounted to extend up from the sidewall. The sidewall includes a filter mesh having a filter mesh size of less than approximately 0.1 inches. At least a portion of each post extends above the filter aperture edge when the filter is mounted to the filter aperture edge. The cap mounts above the plurality of posts. The plurality of posts and the cap form a conduit sized to allow material that cannot pass through the sump mesh to flow through the conduit.

It is an aspect of the present disclosure to provide a dish washing machine capable of actively responding to a problem when circulation of washing water is not smoothly performed by sequentially and selectively performing a bubble removal operation, a filter blockage removal operation, and a water supply operation, and a method of controlling the same.

Provided are systems, methods, and apparatus for spraying water in a dishwasher. A dishwasher may include a wash chamber and at least one dish rack. The dishwasher may include a water inlet selectively connected to a dish spray device, which may connect a dish spray conduit with the wash chamber. The dish spray device may be oriented towards the at least one dish rack, such that the spray device may be configured to direct water onto the dishes for washing. The water inlet may be selectively connected to a fill device, which may connect the fill conduit with the wash chamber. The fill device may be configured to provide water to the circulation assembly without impinging the at least one dish rack. The one or more valves may selectively direct water from the water inlet to one or both of the dish spray device and the fill device.

A dishwasher that includes a tub including an interior area that is configured to receive objects and includes a bottom surface, wherein the bottom surface of the tub includes a first hole; a spray arm that is located in the tub and that is configured to spray water; a sump that is (i) coupled to the tub, (ii) located under the first hole, and (iii) configured to store water; a pump configured to provide water stored in the sump to the spray arm; a cover including a cover body that is coupled to the first hole, and a second hole penetrating the cover body; a supporter including a support body that is coupled to the second hole, and a third hole penetrating the support body; and a filter unit that is coupled to the third hole and that is configured to filter water provided to the sump is disclosed.

A dishwasher may comprise: a tub forming a washing chamber; a sump comprising a bottom portion, a side portion, a water storage chamber formed by the bottom portion and the side portion and configured to store water in the tub, and a first coupling portion formed on the side portion; and a filter coupleable to and decoupleable from the water storage chamber to filter foreign substances from the water. The filter comprises a second coupling portion which rotates to be coupled to the first coupling portion. While the second coupling portion is coupled to the first coupling portion, the second coupling portion holds the first coupling portion in place along a vertical direction of the washing chamber.

A dishwasher may include: a tub, a water storage chamber disposed below the tub and configured to store water in the tub, a filter disposed inside the water storage chamber and configured to filter water introduced into the water storage chamber, a filter motor configured to generate a rotational force to rotate the filter, and an elastic member comprising an elastic material configured to guide rotation of the filter. The elastic member may include a first body part mountable on an upper portion of the filter and comprising a first opening, and a second body part extending upward from the first body part and including a second opening larger than the first opening.

A filtering device and a tableware washing apparatus, the filtering device includes a rotary filter and a drive assembly. The rotary filter includes a columnar filtering screen configured to filter water from a washing process of the tableware washing apparatus; wherein a diameter of an external circle defined by each mesh of the columnar filtering screen is between 0.2 to 0.5 mm. The drive assembly is connected to the rotary filter and configured to drive the columnar filtering screen to rotate relative to contents within the columnar filtering screen at a relative speed of 100 to 1000 r/min, for separating at least a portion of residue on the columnar filtering screen from the columnar filtering screen.

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.
