  • Publication number: 20220178384
    Abstract: A heating pump includes a driving electric motor; a pump case, wherein a pump cavity and a heating cavity are defined in the pump case, the pump cavity and the heating cavity are roughly arranged side by side in an axial direction and are in communication by means of a communication channel, and a water inlet and a water outlet are formed in the pump case; an impeller arranged in the pump cavity; and a heating member arranged in the heating cavity. Therefore, not only is the size of the heating pump favorably reduced, the impeller may also be prevented from being radiated at a temperature by the heating member, such that the premature aging of the impeller may be prevented, and thus, the usage performance of the heating pump may be improved.

  • Publication number: 20220074428
    Abstract: A heat collecting pump includes: a flow guide member, including a flow guide body and a flow guide blade, wherein the flow guide blade is disposed on an outer peripheral wall of the flow guide body; a heating member, disposed on a periphery of the flow guide member and spaced apart from the flow guide blade. The flow guide blade enables water to flow along the outer peripheral wall of the flow guide body to form a first whirlwind flow and to further form a second whirlwind flow in a gap between the heating member and the flow guide blade. Projections of velocity directions of the first whirlwind flow and the second whirlwind flow on a reference plane perpendicular to the axial direction of the flow guide body are in opposite directions; and the second whirlwind flow removes bubbles gathered on the heating member.
