A pump sends washing water and generates steam in order to wash the dishes or the cooking utensils, and a dishwasher including the same. The pump includes a housing, an impeller disposed inside the housing and configured to flow washing water, and a heater coupled to a lower side of the housing and configured to generate steam by heating the washing water in the housing. The housing includes a pump lower portion configured to receive the washing water based on rotation of the impeller, and a pump upper portion configured to discharge the washing water based on rotation of the impeller and to discharge the steam generated by the heater.

Pump and dishwasher comprising the same

A dishwasher includes a cabinet, a tub, a door, a control panel that is disposed in one side of the door and has an operation button, a printed circuit board that is disposed inside the control panel and detects an input for the operation button, a supporter that has a mounting space in which the printed circuit board is mounted and that is disposed inside the control panel, a waterproof film that is adhered to one side of the supporter facing the control panel and blocks water inflow into the printed circuit board disposed in the mounting space, and a coating layer filled with a waterproof material, in the mounting space of the supporter on which the printed circuit board is mounted.

Dishwasher

The present disclosure relates to a pump for transmitting washing water and generating steam and a dishwasher including the pump. The pump includes a housing; a washing water inlet pipe coupled to the housing to receive washing water; a washing water outlet pipe coupled to the housing to discharge the washing water; an impeller disposed in the housing to discharge the washing water from the washing water inlet pipe to the washing water outlet pipe; a heater coupled to the housing to heat the washing water in the housing and generate steam; a steam discharge pipe to discharge the steam generated by the heater; and a selector valve coupled to the steam discharge pipe to block the discharge of the washing water and allow the steam to be discharged, thereby preventing the discharge of washing water through the steam discharge pipe.

A method for controlling a dishwasher includes: supplying washing water to a sump; rotating an impeller disposed in a washing pump by a washing motor so that the washing water flows into the washing pump from the sump; operating a heater disposed in the washing pump so as to heat the washing water existing in the washing pump and generate steam to supply to a steam nozzle; and supplying the washing water or steam in the washing pump to the steam nozzle by rotating the impeller at a second set rotational speed lower than a first set rotational speed by the washing motor. The method further includes closing a selector valve, configured to open and close a path between the washing pump and the steam nozzle, when the impeller rotates at the first set rotational speed or higher.

Dishwasher and controlling method therefor

Disclosed herein is a pet bath. The pet bath includes a casing provided with an entrance formed in a front surface thereof and having an open upper surface so as to form a bathing enclosure, a door configured to open and close the entrance, and upper shower nozzles disposed at a position higher than the upper surface of the casing to spray water to the inside of the bathing enclosure.

Pet bath

The present disclosure relates to a dishwasher for washing the dishes and the cooking utensils by spraying washing water and steam. The dishwasher according to an embodiment of the present invention includes a tub which accommodates a washing object, a sump which is disposed in a bottom of the tub and stores washing water, a spray arm which sprays the washing water into the tub, a washing pump which sends the washing water stored in the sump to the spray arm, and a check valve which is disposed between the sump and the washing pump and opened in a direction of the washing pump from the sump.

A dishwasher includes: a case; a tub; a door; a sump disposed below the tub and configured to store washing water; a spray nozzle configured to spray washing water into the tub; a heater configured to heat washing water and generate steam; a steam nozzle disposed at the door or the tub and configured to discharge steam to the tub; a first rack disposed in the tub and configured to receive a washing target to be washed by washing water sprayed from the spray nozzle; and a second rack disposed in the tub and configured to receive a washing target to be washed by steam supplied from the steam nozzle. The steam discharged from the steam nozzle is supplied to an inside of the second rack through one of a lower surface or a circumferential surface of the second rack.

A dishwasher is proposed. The dishwasher includes a case accommodating a cleaning target therein, a sump connected to an interior of the case to collect wash water, a wash pump into which the wash water flows from the sump, and generating steam, a steam nozzle into which the steam flows from the wash pump, and spraying the steam into the case, and a bubble filter disposed on a steam path between the wash pump and the steam nozzle to remove a bubble in the steam path.

Disclosed herein is a pet bath. The pet bath includes an outer cabinet and an inner cabinet having open front surfaces, a door configured to open and close the open front surfaces of the outer and inner cabinets, a water collection tank to form a washing water storage space, a circulation pump to pump the washing water stored in the water collection tank, a lower nozzle and at least one upper nozzle to spray the washing water pumped by the circulation pump into a bathing enclosure, a stand disposed between the lower nozzle and the at least one upper nozzle, a circulation water filter to filter washing water, an air blower to circulate air in the bathing enclosure, and air nozzles to discharge air to an inside of the bathing enclosure, and inner exhaust holes to exhaust air are formed in an upper surface of the inner cabinet.

Disclosed herein is a pet bath. The pet bath includes an outer cabinet to form an external appearance of the pet bath and having an open front surface, an inner cabinet provided within the outer cabinet to define a bathing enclosure and having an open front surface, a door configured to open and close the open front surfaces of the outer and inner cabinets, a washing device to spray washing water to the inside of the bathing enclosure, an air blower disposed between the outer cabinet and the inner cabinet, an air heater to heat air flowing due to operation of the air blower, and a plurality of air nozzles rotatably disposed on at least one surface of the inner cabinet and having air nozzle holes, and the air nozzle holes are spaced apart from centers of rotation of the corresponding air nozzles by a designated distance.

A dishwasher includes: a tub that defines an washing chamber; spray nozzles configured to spray washing water into the washing chamber; a sump configured to store washing water; a steam nozzle configured to supply steam to the washing chamber; a washing pump housing coupled to the sump and connected to the spray nozzles or the steam nozzle; a heater configured to heat washing water in the washing pump housing; a washing motor configured to rotate an impeller; a washing water outflow pipe defining an outflow path protruding outward from one side of the washing pump housing; a steam discharge pipe that extends from a discharge port defined at a circumferential surface of the washing water outflow pipe; and a first protrusion disposed in an upper portion of the outflow path and disposed downstream of the discharge port in a flow direction of the washing water.

A dishwasher includes a case, a sump connected to an inside of the case and collecting washing water, a washing pump receiving washing water from the sump and generating steam, and a steam nozzle connected to the washing pump and spraying steam to the inside of the case. The steam nozzle includes a steam nozzle body having a steam inlet and including a steam accommodating portion accommodating steam therein, a first steam sprayer provided in the steam nozzle body and spraying steam to the inside of the case, and a second steam sprayer provided in the steam nozzle body and disposed at a position farther from the steam inlet than the first steam sprayer, wherein a tunnel flow path penetrating through a lower end of the first steam sprayer is formed to allow steam passing through the tunnel flow path to be introduced into the second steam sprayer.
