And pumped into a pure source carried directly from the spa bath of the spa house, method and apparatus for maintaining the purity and freshness of the source

摘要

PURPOSE:To perform a hot spring cure without going to a hot-bath resort by keeping the freshness of the headspring by filling an underground hot water storage tank with the pure headspring and removing the contaminant of the headspring by a hot spring filter to heat the headspring by a heat exchanger. CONSTITUTION:An underground hot water storage tank 1 is filled with the pure headspring and the headspring is pumped up by a primary pump 2. The circulating hot water heated by a boiler 3 is passed through a pipe 10 to be recirculated to a heat exchanger 4 and the headspring is heated by the heat exchanger 4 to be received in a hot spring storage tank 5. The purity of the headspring can be kept without changing the components of the headspring. When the water level of a hot spring bathtub 6 lowers, the headspring is sent into the bathtub 6 by a secondary pump 7. When the headspring of the hot spring bathtub 6 is contaminated, the headspring is sent to a hot spring filter 8 by a pump 13 through a pipe 14 to remove contaminant and sent in the hot spring bathtub 6 through a pipe 15. When the temp. of the headspring lowers, the temp. of the headspring is raised by a heat exchanger 9 and the headspring is circulated to keep the freshness and purity of the headspring.
