As a result, the effect of saving water can lead to more waste of tap water.

Accordingly, an object of the present invention is to solve the problems of the prior art at once, the well-known one-touch manual faucet that makes it very easy to adjust the water temperature and water temperature by mixing the hot and cold water, the valve is opened and closed by the operation of the sensor at the same time the manual method The automatic faucet control valve device that can be opened and closed is provided as a faucet, characterized in that the assembly or integrally combined.

In this way, the present invention automatically adjusts the water supply by the operation of the sensor while maintaining the functions and advantages of the well-known one-touch manual faucet, which makes the adjustment of the water quantity and the water temperature very easy. It is to provide a tap that can be harvested.

To this end, the present invention adopts a known one-touch manual faucet, which is very easy to adjust the quantity and water temperature as illustrated in Figures 1a and 1b.

As described above, the one-touch manual faucet has a structure in which water is controlled by vertical operation of the handle levers 10 and 20 and water temperature is controlled by left and right operations, thereby controlling water and water temperature very quickly and easily. do.

Since the configuration and operation principle of a known one-touch manual faucet is already known, a separate description thereof will be avoided, and by the operation of the sensor 41 and a manual opening / closing control device to be coupled to the one-touch manual faucet. Looking at the automatic manual control valve device for opening and closing the valve 42 as follows.

The configuration and action of the automatic valve device itself, which is opened and closed depending on whether the sensor 41, in particular, the approach of the human body through the pyroelectric infrared sensor, is already known, is a pyroelectric infrared sensor installed in the faucet jetting unit 40. When the 41 detects the human body approach and sends a detection signal to the valve control unit, the valve control unit opens the valve 42 installed in the drain pipe so that the tap water comes out through the faucet water jetting unit 40 and the human body approach is resolved to detect the human body approach. If not, the valve 42 is closed by the valve control unit so that the tap water is not supplied.
