Heat collecting pump and washing appliance having the same

A washing appliance comprising a heat collecting pump including:

• a housing with an accommodation cavity, the housing having a fluid inlet and a fluid outlet;
• a heating device disposed in the accommodation cavity;
• a drive device connected to the housing and configured to drive a fluid to flow from the fluid inlet to the fluid outlet;
• and
• a flow guiding element disposed in the accommodation cavity;
• wherein:
• the flow guiding element has an inner wall forming a fluid inlet channel in communication with the fluid inlet;
• a fluid discharge channel is formed between an outer wall of the flow guiding element and an inner wall of the accommodation cavity, the fluid discharge channel being in communication with the fluid inlet channel and the fluid outlet;
• the flow guiding element includes:
• a flow guiding portion configured to guide a fluid in the fluid discharge channel towards the fluid outlet;
• and
• a water inlet portion;
• the heating device includes a heating tube sleeved on and spaced apart from the water inlet portion;
• the flow guiding portion includes:
• a connection body having an end connected to the water inlet portion and another end obliquely extending outwards away from the water inlet portion;
• and
• a plurality of flow guiding ribs arranged at intervals at another end of the connection body in a circumferential direction of the connection body;
• at least part of an outer peripheral wall of the water inlet portion has a cylindrical surface;
• and
• each of the plurality of flow guiding ribs has:
• a first flow guiding surface spirally extending in the axial direction of the water inlet portion, the first flow guiding surface being perpendicular to the cylindrical surface;
• and
• a second flow guiding surface spirally extending in the axial direction of the water inlet portion, the second flow guiding surface being parallel to the cylindrical surface.
