Abstract
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.
Claims10
An electric water pump, comprising:
- a housing partitioned into a distribution space where fluid is distributed and a driving space into which a motor is built, the distribution space having a plurality of inlets and outlets communicating with an outside;
- and
- an impeller provided in the distribution space of the housing and connected to the motor to rotate, formed so that the distribution space is partitioned for each inlet and outlet that communicate with each other among the plurality of inlets and outlets, and pumping the fluid to each inlet and outlet when rotating by driving of the motor,
- wherein the housing is separately composed of a case and a cover,
- an upper portion of the case is opened upward to form a portion of the distribution space, and form a driving space with the built-in motor at a lower side, and
- a lower portion of the cover is opened to form the rest of the distribution space and is coupled to an upper portion of the case,
- wherein the distribution space is partitioned into a first distribution part on the case side and a second distribution part on the cover side by the impeller,
- wherein the case is formed with the first distribution part that is recessed along an outer side of the distribution space, and
- the cover is formed with the second distribution part that is recessed along the outer side of the distribution space.
