Description
Technical Field
[0001] This utility model relates to the field of dishwashers, and more particularly to a dishwasher spray system and a dishwasher. Background Technology
[0002] Dishwashers are common household appliances, typically installed inside kitchen cabinets. They use recycled water for each wash cycle and usually incorporate a spray system at the bottom. A wash pump sprays water upwards onto the dishes to achieve the washing function. However, existing dishwasher spray systems require an opening in the base connecting the inside and outside of the dishwasher. The wash pump connector is installed in this opening, with the lower part of the connector housing the pump and the upper part connecting to the spray arms, allowing water to be sprayed from different spray arms. This design, combined with the washing process, creates a cyclical and complex process. The pump connector is installed on the base of the dishwasher, located at the bottom. To prevent water from leaking out of the dishwasher, a sealing ring needs to be installed. Because the inside of the dishwasher is a high-temperature and high-humidity environment, and the dishes contain corrosive substances such as oil, salt, acid, and salt, the sealing ring is easily damaged. The quality requirements for the sealing ring are extremely high, and multi-stage sealing is generally used. The production control and inspection requirements for the dishwasher are also high. However, due to long-term use in this environment, if the sealing ring is not sealed tightly, water inside the dishwasher will flow out of the dishwasher, making the dishwasher unable to work properly and affecting the use of the entire kitchen cabinet.
