Abstract
A water pump including an upper casing and a lower casing that are formed with an inlet into which fluid is introduced and an outlet through which the fluid is discharged; and an impeller that is accommodated inside, formed by the coupling of the upper casing and the lower casing. The impeller is formed with a down force generation part that generates a force that pushes the impeller downward by coming into contact with fluid within a flow path through which the fluid passes and the down force generation part is formed such that a height of an ending point (E) is higher than a height of a starting point(S).
Claims10
A water pump, comprising:
- an upper casing and a lower casing that are coupled to each other to form an impeller accommodation space in which an impeller is rotatably accommodated, and have an inlet formed above the impeller accommodation space to communicate with the impeller accommodation space and to allow fluid to flow in, a discharge channel formed radially outside the impeller accommodation space to communicate with the impeller accommodation space, and an outlet connected to the discharge channel to discharge the fluid to an outside;
- and
- an impeller that is rotatably provided in the impeller accommodation space,
- wherein the impeller is formed with a down force generation part that generates a force that pushes the impeller downward by coming into contact with fluid within a flow path through which the fluid passes, and
- the down force generation part is formed such that a height of an ending point (E) is higher than a height of a starting point(S).
