Provided are a heat collecting pump and a washing appliance. The heat collecting pump includes: a housing defining an accommodation cavity and having a fluid inlet, a fluid outlet, and a mounting opening; a heating device and a flow guiding element that are 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. The flow guiding element has an inner wall defining a fluid inlet channel in communication with the fluid inlet. A fluid discharge channel is defined between an outer wall of the flow guiding element and an inner wall of the accommodation cavity, and is in communication with the fluid inlet channel and the fluid outlet, respectively. The flow guiding element has a flow guiding portion configured to guide a fluid in the fluid discharge channel towards the fluid outlet.

An indoor unit of an air conditioner includes a housing having an opening, a heat exchanger arranged in the housing to heat exchange air drawn into the housing, a fan arranged in the housing and rotatable around a rotation axis. The rotation axis formed to extend along a direction toward the opening and a diffuser placed at the opening and through which heat exchanged air blown by the fan is discharged. The diffuser including a plurality of vanes configured to guide the heat exchanged air blown by the fan. The diffuser being further configured to be selectively rotatable in the same direction as a rotation direction of the fan. The fan and the plurality of vanes being arranged to guide the heat exchanged air blown by the fan in the rotation direction of the diffuser while the diffuser is rotated.

Downhole centrifugal pumps and related components and methods may include diffusers housing impellers where the diffusers have radial sidewalls defining a radially outer portion of each of the diffusers. Coupling members may extend between and engage with the diffusers.

The present invention provides an electric water pump in which a plurality of inlets and outlets for the distribution of fluid are provided in one housing, and the fluid is pumped into each space by an rotational operation of one impeller in a state where a space is partitioned for each inlet and outlet through which the fluid is distributed, thereby distributing the fluid through multiple paths with one water pump and reducing costs and weight through structure simplification.

A heat collecting pump includes a housing with an accommodation cavity and having fluid inlet and outlet, a heating device disposed in the accommodation cavity and including a heating tube, 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. 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, and is in communication with the fluid inlet channel and the fluid outlet. The flow guiding element includes a flow guiding portion and a water inlet portion. The heating tube is sleeved on and spaced apart from the water inlet portion.
