Description

Drain system of faucet with temperature cut-off control {DRAIN SYSTEM FOR REUSING COOLED WATER IN HOT WATER LINE}

The present invention relates to a drain system for chilled water in a hot water pipe to which hot water from a boiler is supplied, and more particularly, to a drain system for a faucet capable of controlling temperature cutoff.

A faucet is a device that opens and closes water by being located at the end of the water supply pipe, and can be divided into various types according to the installation location, use, or function. Cold water pipes and hot water pipes are installed in rooms where hot water from a boiler is used, such as in a bathroom or shower room. The faucet installed in such a bathroom has a valve device capable of mixing hot and cold water so that the user can meet the desired water temperature.

Hot water pipes such as bathrooms are connected to the boiler, and the hot water in the pipe from the boiler to the faucet cools according to the surrounding temperature while the faucet is not used. Accordingly, even if the mixed water valve is opened in order to use hot water immediately, cold water inside the pipe is often sent for a while. In particular, when the ambient temperature is low, such as in winter, the time for flowing cold water is prolonged, and the user also performs actions such as checking by contacting the body with water while waiting for the hot water to start to reach the desired temperature. It is a small inconvenience in everyday life to receive cold cold water when turning on the water in the shower head for a shower or bath, but it may be a fatal threat to a user with heart disease or poor health due to the temperature difference caused by the sudden cold water. have.

A faucet is the final source of water in a home or building that uses water, but depending on the degree of its use, the amount of water consumed may vary. Water shortage is a serious situation in the world including Korea, and water conservation is requested as a practical solution. As in the above situation, the cold water in the hot water pipe that flows directly into the sewage can be regarded as a waste of valuable water resources. To this end, a technology that allows water cooled through the operation of a faucet to be drained through a separate pipe other than sewage has also been developed. In addition, there have been technical attempts to store cold hot water in hot water pipes and recycle it to toilets.
