Dishwasher with plastic collector connected to centrifugal pumps - has connecting tubes between pumps and external coupling cocks formed in prefabricated trough and motor assembly

摘要

In the floor of the inner housing (2) a plastic trough (3) for collection of rinse water from surrounding sprays (4-6) is connected to two pump casings (7,8). The trough (3) is assembled from several shaped components welded together and fitted with movable and stationary machine parts. The stators (13,14) of the pump motors are mounted externally for co-operation with e.g. a squirrel-cage rotor (20) and a turbine wheel (21). ADVANTAGE - Mfg. costs of collector, pumps and tubing are reduced with employment of larger prefabricated units and simplified final assembly. Susceptibility to leakage is also reduced.
