Description

Technical Field

[0001] The utility model belongs to the technical field of dishwashers, and in particular relates to a spray system for a dishwasher and the dishwasher. Background Art

[0002] Current washing machines generally include a housing having a washing chamber, a spray device and a rack disposed in the washing chamber, wherein the spray device is used to draw water from the bottom of the housing into a water spraying component and spray the water into the washing chamber to wash dishes or fruits and vegetables.

[0003] The Chinese invention patent application previously applied by the applicant, "A cleaning basket and a cleaning machine using the cleaning basket", with patent number CN202010898750.0 (application publication number CN114098571A), discloses a cleaning basket provided with a spray arm, a first impeller, a first magnetic part, a second magnetic part, a generator, an AC / DC conversion module and an electrolysis module. The cleaning basket is convenient for combining with a water tank to form a cleaning machine. When in use, the cleaning basket is placed in the water tank, and the rotation of the second magnetic part drives the first magnetic part and the spray arm and the first impeller to rotate, drawing the water at the bottom of the cleaning basket into the spray arm and further spraying the water upward, cooperating with the turbulent water flow to improve the cleaning effect. However, the drying air inlet is usually set on the upper layer, with a small coverage area, poor fluidity of the drying gas in the tank body, and water accumulation is prone to occur on the lower side of the tank body, resulting in a poor drying effect experience.

[0004] Therefore, it is necessary to further improve the existing cleaning basket structure. Utility Model Content

In this way, when the drying function is turned on, after the external hot air flows through the air inlet pipe into the air channel of the first sub-spray arm, a part of the drying gas flows vertically downward directly into the auxiliary spray part of the first sub-spray arm, causing the auxiliary spray part to rotate while continuously spraying drying gas from the spray hole. Another part of the drying airflow enters other air passages, a part of the hot gas is ejected through the corresponding jet holes, and the other part causes the corresponding auxiliary spraying parts to rotate while continuously ejecting drying gas from the corresponding spray holes, thereby achieving comprehensive drying of the bottom.

[0022] Preferably, the bottom wall of the auxiliary spraying member is provided with an overflow hole, which can be used to flush the residue in the lower area during washing, and can also allow the drying air flow to spray out through the overflow hole to dry the lower area and avoid water accumulation.

[0023] Preferably, the top wall plate of the spray element is a portion of the bottom wall of the cleaning basket.

[0024] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a dishwasher, including a box body and a washing basket structure, the interior of the box body has a washing chamber, characterized in that: the washing basket structure is the washing basket structure described above, and is arranged in the washing chamber, an air inlet connected to the air inlet duct is opened on the side wall of the box body, and along the air flow path, the air inlet is located upstream of the air inlet duct.
