Description

TECHNICAL FIELD The present invention relates to a faucet device, and more particularly to a faucet device configured to automatically spout water from a spout based on human body detection by a sensor, for example.

Currently, faucet devices are widely used that are configured to automatically spout water from a spout based on human body detection by a sensor.
However, in the case of a structure in which two or more horizontal holes are drilled in a long pipe-shaped object and sensors and buttons are arranged in the horizontal holes, the two or more sensors and buttons are fixed to the pipe by some kind of member. It will be incorporated. In that case, assembly cannot be performed unless both the dimensional accuracy of the distance between the lateral holes of the pipe and the dimensional accuracy of the fixing member on the sensor side are good. Then, a problem such as hindering the operation of the button occurs.

The outflow pipe 234 extends downward and is connected to the electromagnetic valve unit 210, and the flexible water supply pipe 18 extending from the electromagnetic valve unit 210 is connected to the water discharge head 14 via the annular member 12. ing.
The water supply pipe 18 is fitted with a stopper 242 so that it can be stopped by a predetermined device. there is

Inside the cabinet 200, a power board 212 is provided to supply electric power to the first switching device 30, the second switching device 40, the third switching device 50, the connecting part 60, and the solenoid valve unit 210. As shown in FIG.
The power supply board 212 includes a control device for controlling the first switching device 30 , the second switching device 40 , the third switching device 50 , the connecting part 60 and the electromagnetic valve unit 210 . The solenoid valve unit 210 and the power supply board 212 are electrically connected by a cord 240 .

As shown in FIGS. 3 and 4, in this embodiment, water and hot water from the water supply source pipe and the hot water supply source pipe are supplied to the main body 180 of the faucet through the water supply pipe 232 and the hot water supply pipe 230. It is supplied to the built-in mixing valve 184 .
The supplied cold water and hot water are mixed in a predetermined ratio based on the operation of the single lever handle 182, and then flowed through the water supply pipe 18 to the water discharge head 14 at a predetermined flow rate also determined based on the operation of the single lever handle 182. and spouted from a spout 70 at the tip.
Here, the single lever handle 182 adjusts the mixing ratio of cold water and hot water, that is, adjusts the temperature by turning left and right, and adjusts the flow rate by turning up and down.

As described above, the embodiments of the present invention are disclosed in the above description, but the present invention is not limited thereto.
That is, without departing from the scope of the technical idea and purpose of the present invention, various modifications can be made to the above-described embodiments in terms of mechanism, shape, material, quantity, position, arrangement, etc. and they are included in the present invention.
