Abstract (en)
[origin: US2005201878A1] A centrifugal pump ( 1 ) is proposed, in particular for household appliances, such as washing machines or dishwashers, which comprises a pump housing ( 2 ) having an axial inlet ( 11 ), an outlet ( 12 ) and a heating element, wherein the pump housing ( 2 ) incorporates a rotatably mounted impeller ( 4 ) and a flow channel ( 15 ) enveloping the impeller ( 4 ) and heating element. The centrifugal pump ( 1 ) according to the invention is intended to have improved efficiency. This is achieved by having the flow cross-section of the flow channel ( 15 ) increase along the periphery toward the outlet ( 12 ).
