The present invention relates to a hot water circulation apparatus for a hot water mat. Conventional hot water mats have the problem of employing a circulation motor for circulating hot water, thereby generating noise and disturbing the sleep of a user. Conventional hot water mats also have the problems of the circulation motor operating at a high temperature and thus having a short lifespan, and of a hot water hose being pressed by the weight of the user during use, wherein the pressure being applied to the hot water hose causes an increase in the noise of the circulation motor and shortens the lifespan of the circulation motor. To solve the above-mentioned problems of conventional hot water mats, the present invention provides a hot water circulation apparatus using steam, which can circulate hot water by means of steam instead of using the circulation motor employed in conventional hot water mats. Further, the present invention provides a hot water circulation apparatus for a hot water mat which overcomes the problems of conventional hot water circulation apparatuses using steam, wherein steam might be introduced into the pipe of the hot water mat to cause noise due to air bubbles, water leakage, or an interruption in circulation of the hot water. Thus, the hot water circulation apparatus for a hot water mat according to the present invention more effectively prevents air bubbles from being introduced into a water tank or into the pipe. |
