Abstract

PURPOSE:To reliably detect the water current and prevent muck from being stuck by providing a detection sensor on the faucet opening section to detect an object below the faucet from above. CONSTITUTION:A power supply is invariably fed to a control circuit unit 8, and a detection sensor 14 always searches for the presence of an object by emitting a signal below the faucet opening section. When no object is found, the power supply is not fed to a solenoid 1. When the detection sensor 14 detects object, the power supply is fed to the solenoid 1 from the control circuit unit 8 and a plunger 5 pulled into the interior of the solenoid 1 cylinder, thereby the valve 4 is separated from the main body 7, thus feeding water. since the detection is performed from the upper direction, the water current is not detected unless a disturbance occurs in the water current, and if the detection sensor 14 is housed in the pipe, it is not different from an ordinary aqueduct pipe in shape, and furthermore, no muck is stuck to it and its fixing and wiring can be reliably accomplished.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a water faucet that detects the presence or absence of an object below the faucet opening and automatically opens and closes the valve.Conventional structure and problems thereof Most of these types of faucets have a detection part attached to the outside of the faucet and detect objects below the faucet opening.
Since the detection part protrudes, problems have arisen in which objects can hit it or dirt can cover the detection part. In addition, the detection part is more sensitive than the faucet part, which is inconvenient in terms of design.

Purpose of the Invention The present invention takes into account the above problems and provides reliable water flow detection.
Another object of the present invention is to provide a water faucet that is resistant to adhesion of filth.

Structure of the Invention In order to achieve the above-mentioned object, the present invention comprises a valve for opening and closing a waterway in a main body, a solenoid for driving the valve, and a control circuit unit for a detection sensor formed by the solenoid, an emitter, a light-receiving element, etc. , a water faucet with a faucet connected to a waterway inside the main body, equipped with a detection sensor at the faucet opening,
DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a solenoid, which is attached to the main body lid 2 with screws 3. Reference numeral 4 denotes a valve, which is integrated with the plunger 6 and fitted into the cylindrical portion of the solenoid 1 through the spring 6. The main body lid 2 is attached to the main body 7 with the screws 3, and a water channel that is opened and closed by a valve 4 is formed in the main body T.

Reference numeral 8 denotes a control circuit unit, which is attached to the main body 7 with screws 9. Reference numeral 1o denotes a faucet portion, which is attached to the main body through a joint 11, and has a double pipe configuration of an inner pipe 12 and an outer pipe 13. A detection sensor 14 formed of a light emitting element, a light receiving element, etc. is fitted into the faucet opening of the outer tube 13 of the faucet part 10, and the outer tube 13 is used for wiring. 15 is a cover that covers parts attached to the main body 7, and 16 is a water main.

Next, the operation and operation of the water faucet will be explained. Power is constantly supplied to the control circuit unit 8, and the detection sensor 14I/'i constantly emits a signal downward from the faucet opening to detect the presence or absence of an object.

If there is no object, no power is supplied to the solenoid 1, the valve 4 is brought into close contact with the main body 7 by the spring 6, and the supply of water flowing from the water main 16 is stopped. When the detection sensor 14 detects an object, power is supplied from the control circuit unit 8 to the solenoid 1, and the plunger 6 is drawn into the inner part of the solenoid 1, causing the valve 4 to separate from the main body 7 and water to be supplied. will be done.

Here, when the detection sensor 14 tries to detect an object below the faucet opening from the side, the problem is that once it is detected and water starts flowing, it will detect the water flow again and keep the valve 4 open. However, if it is detected from above, the water flow will not be detected unless the water flow is disturbed. In addition, if the detection sensor 14 is placed inside the pipe, the shape is no different from that of a normal water pipe.
Furthermore, fixing and wiring can be performed reliably.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention is equipped with a detection sensor at the faucet opening and detects objects at the bottom of the faucet from the upper part. It is effective and of great value.
