Jet pump with filter for washing machines |
摘要 |
A clog resistant pump for washwater employs two water flow circuits. The first powered by a conventional motor-driven pump uses filtered washwater and drives a jet-pump discharging unfiltered washwater from the washing machine. The intake or discharged water from the jet-pump is used to operate a self-cleaning filter providing water for the first circuit of the motor-driven pump. The position of the filter in the stream of wastewater and adjustment of the filter apertures in size and area reduce clogging yet allow sufficiently filtered water to permit a conventional high efficiency motor-driven pump to be used in the first stage.
