Benefits of technology
[0009] One object of the present invention is to provide a motor rotator structure of a hot water circulating pump, for preventing water penetration into a rotator.
[0010] Another object of the present invention is to provide a motor rotator structure of a hot water circulating pump, for preventing disengagement of a sealing cap from both ends of a rotator core.
[0011] A further object of the present invention is to provide a motor rotator structure of a hot water circulating pump, in which a sealing cap is formed of silicon having excellent water-tightness.
[0016] In other words, in the present invention, the rotator has a water leakage prevention function so that, in use, hot water is prevented from being penetrated into the rotator core and constituent parts of the rotator are prevented from being corroded or damaged.
Problems solved by technology
However, the conventional hot water circulating pump 100 causes the following drawback in use.
However, due to absence of the water leakage prevention function, the conventional rotator 116 has a drawback of, with lapse of time, corroding their internal constituent parts and losing their functions.

Provided is a motor rotator structure of a hot water circulating pump. The structure includes a metal pipe whose interior is empty, a rotator core, and sealing caps. The rotator core is inserted into the metal pipe. The sealing caps are fitted into both sides of the rotator core, respectively. The metal pipe is inwardly rolled at both ends such that the sealing caps are compressed and fixed to the rotator core.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority of Korean patent application No. 2005-22597 filed on Mar. 18, 2005, the content of which is incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to a motor rotator of a hot water circulating pump, and more particularly, to a motor rotator structure of a hot water circulating pump, for preventing water penetration into a rotator. BACKGROUND OF THE INVENTION [0003] As well known in the art, a hot water circulating pump, a unit for driving an impeller by motor power and forcibly supplying hot water to each use, is being variously used in a whole industry. [0004] A construction of a conventional hot water circulating pump is shown in FIG. 1. [0005] Referring to FIG. 1, the hot water circulating pump 100 includes a stator 112 for receiving an electric current from a coil; a motor housing 114 installed to pass through the stator 112, and inserting a shaft 118 and...
