Abstract
Description
The present invention relates to a hot water circulation pump. More particularly, the present invention relates to a hot water circulation pump capable of effectively removing bubbles generated inside a pump and effectively discharging a fluid located under the impeller, thereby reducing noise through stable operation of the impeller.
Generally, a low-pressure boiler or a hot water mat has a hot water circulation pump for circulating heated hot water. Such a hot water circulating pump is applied to the same principle as a motor. An impeller including a rotor serves to discharge hot water introduced into an inlet through an outlet while rotating by electromagnetic interaction with a stator.
A prior art for a hot water circulation pump is Korean Patent No. 10-1204344. In this prior art, the hot water introduced into the inlet port formed on the upper portion of the hot water circulation pump is discharged to the outlet port formed on the side surface by the rotation of the impeller. On the other hand, the hot water flowing between the lower part of the impeller and the inner housing moves upward through a flow path formed vertically through the impeller, and is discharged to the discharge port together with the hot water flowing from the upper part of the impeller blade. The discharge hole ensures stable rotation of the impeller and prevents the impeller from rising.
However, in this prior art, since the fluid that has risen by the discharge hole collides with the fluid flowing in the upper portion from the inside of the impeller, the rotation of the impeller may become somewhat unstable, and furthermore, When I do, I get an unpleasant noise similar to the sound I hear. Since the hot water circulating pump is used in a hot water mat, the unpleasant noise generated at the time of sleep interferes with the sleeping surface, and the quality of the hot water mat is deteriorated.
Further, in the prior art, the direction of the flow of the fluid flowing from the shaft portion and the inner space of the impeller is changed on the suction port side. In the space where the direction is changed, bubbles are generated and noise is generated.
In order to solve such a problem, the present inventor proposed a hot water circulation pump of a new structure capable of smoothly flowing air and fluid inside the impeller and preventing the generation of bubbles in a space where the inflow direction of the flowing fluid changes do.
