Abstract
A heating pump includes a motor, a housing fixed to the motor, an impeller driven by the motor and received in the housing, and a tubular heating member fixed in the housing. The housing includes an intake tube and a discharge port arranged at the periphery of the intake tube. The impeller includes an inlet communicating with the intake tube and a plurality of outlets around the inlet. The outlets communicate with the discharge port via a first passage surrounded by the heating member. A second passage, which communicates with the first passage, is formed between a radially outer surface of the heating member and a radially inner surface of the housing.
