Description

[0001] FAUCET AND WATER SAVING FAUCET SYSTEM FOR BUILDINGS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet and waterproof faucet system of a building.

The faucet is located at the end of the water pipe to open and close the water, and can be divided into various types depending on the installation location, application or function. In a room using hot water such as a bathroom or a shower room, a cold water pipe and a hot water pipe are installed. The faucet installed in such a bathroom is provided with a valve device capable of mixing hot water and cold water so that the user can adjust the desired water temperature.

Hot water pipes such as bathrooms are connected to the boiler. The hot water in the pipe from the boiler to the water pipe is cooled while not using the faucet. Therefore, even if the mixed water valve is opened to use the hot water immediately, the inside of the pipe flows cold water for a while. Particularly, when the ambient temperature is low, such as winter, the cold water flow time becomes longer, and the user also starts to come out of hot water and waits until the desired temperature is reached. Although it is a minor inconvenience of everyday life when the shower water is used for shower or bath, cold water is a fatal danger for people with poor heart health or bad health due to the cold water being discharged. .
