Pipe Structure for Cool and Warm Water

The present invention relates to a pipe structure for cold and hot water, and more particularly, to a cold and hot water pipe structure to improve the structure of the housing and the refrigerant / heater pipe so that the incoming water flows directly through the housing to be directly hot and cold.

In general, anyone has a basic desire to drink clean water, and the general tap water supplied to the household by these needs is used for washing or cleaning, and drinking water is used as drinking water or drinking water through a water purifier. It is purified and used as drinking water. In recent years, interest in drinking water has been increasing, and this interest has led to the development and development of water purifiers that purify water, and is expected to provide drinking water that considers the health of the body by means of higher performance water purifiers. have.

Water purifiers provide clean drinking water by filtering out various foreign substances and harmful substances contained in the water, and the demand is increasing day by day due to the overcrowded population and industry, the rapid growth of urban areas, and the abuse of land use. The surrounding environment is polluted by this, and the pollution of the surface water which receives various sewage is intensified, resulting from the ignorance of tap water. In other words, since industrial wastewater, livestock wastewater, etc. are introduced into surface water used as a water supply source, the pollution degree is getting worse and it is becoming inadequate as drinking water.

Therefore, as mentioned above, due to the interest in drinking water and the expectation of water purifiers having various functions, much effort and cost have been invested in research and development of water purifiers. The widespread use of water purifiers is common.
