Abstract (en)

[origin: WO0028878A1] The invention relates to a circulating pump, notably for a water-circulating household appliance, such as a dishwasher or washing machine, which is provided with a wash tub and an electric heating device (17) for heating the wash-water, as well as a pump housing (14) which is flange-mounted on the motor housing of the pump and has suction and pressure stubs (15, 12, 13) for the liquid to be circulated and heated in the circular flow. Safety devices, such as thermostatic switches, pressure switches or such like are possibly provided for for monitoring the liquid to be circulated in the water circuit. According to the invention the heating device (17) is removably mounted on the pump housing (14) in the water circuit of the pump. The combination of heating device (17) and pump (11) and the positioning of same in the water circuit of said pump (11), preferably in the pump housing (14), permits the rapid and loss-free transfer of heat to the circulating wash-water. The heating system is thus able to operate in a highly efficient and energy-saving manner.
