Abstract (en)
[origin: EP3751150A1] A heating pump and a washing appliance. The heating pump includes a pump housing (1) and a pump cover assembly (2). The pump housing (1) includes an outlet and a side wall (11) extending around the outlet. The pump cover assembly (2) includes an annular support portion (21) covering the outlet and a heating element (22) thermal-conductively mounted on the support portion (21). The support portion (21) separates the heating element (22) from fluid in the heating pump, and a surface of the support portion (21) in contact with the fluid is flat. The heating pump and the washing appliance of the invention can heat the fluid while pumping, and are simply structured. The surface of the support portion in contact with the fluid is flat, thus reducing the friction between the fluid and the support portion, improving the pump efficiency and reducing the energy consumption.
