Dual outlet circulation pump for domestic dish washer - uses axial inlet pump with restricted clearance to casing between two water outlets to give differential water flow

摘要

The circulation pump has two baskets placed one above the other in the bowl of the washer and has at least two water sprays supplied by the circulation pump. It comprises a cover, a wheel mounted inside the cover, an axial water inlet, and two outlet pipes fixed to the cover near the periphery of the wheel. The casing (1) is shaped to provide reduced clearance between the casing and the wheel (2) in the region between the two outflow pipes (3,4). This configuration results in differential flow rates between the two outlets, and the pump rotation is reversible to allow either outlet to be used, for example, for delicate dishes.
