Description

Technical Field

[0001] The present disclosure relates to the technical field of dishwashers, and in particular to a water cup assembly with a water diversion valve structure. Background Art

[0002] With the improvement of living standards, dishwashers are growing and developing as products that improve the quality of family life. In order to achieve a better washing effect, existing dishwashers are generally designed with multiple spray arms to clean the dishwasher. In order to save water resources, a water circulation system is set inside the dishwasher to filter and extract the washing water in the inner tank and return it to the spray arm. The water circulation system usually includes a water collection tray set at the bottom of the inner tank, a water cup assembly set at the low point of the water collection tray, and a filter cup set on the water pump. The water cup assembly is provided with a water outlet joint, which is connected to the water inlet of the washing pump. Under the action of the washing pump, the water collected by the water collection tray flows downward to the water cup assembly, and after being filtered by the filter cup of the water cup assembly, it flows to the washing pump, and then is re-delivered to the spray arm after being pressurized by the washing pump. The water cup assembly is also connected to a drain pipe and a drain pump, and the waste water of the water cup assembly is discharged from the drain pipe under the action of the drain pump.

[0003] Existing dishwashers usually include three spray arms: top, middle and bottom. During washing, the water in the water collection tray is transported to the top, middle and bottom spray arms respectively through a washing pump, and then sprayed from the three spray arms to rinse the tableware. After that, the water flows back into the water cup from the bottom of the washing machine, and the washing pump transports the returned water to the above three spray arms again, completing a cycle. The cycle is repeated in this way to achieve the cleaning of the tableware.

[0004] In order to achieve the purpose of water conservation while ensuring the cleaning effect, a diverter is usually set in the water supply pipeline of the dishwasher. The opening or closing of each spray arm is realized by the cooperation of the water diverter and the diverter, so as to reduce the amount of water required for the cleaning cycle. For example, the patent No. 202320334178.4 discloses a spray arm diverter device and a dishwasher. The patent can reduce the risk of water leakage caused by the wear and deformation of the water diverter after long-term use, but the structure of the spray arm diverter device is relatively complex, and it is difficult to form, with a low forming rate and high cost.
