用途にも利用されている。[0003] Sensor-type automatic faucets are also inadequate for sanitary and sensory facilities to be opened and closed directly with facilities for the elderly and the physically handicapped who have difficulty operating the valve, and with hands that have detergent or dirt. It is also used for mixing faucets in appropriate kitchens. Furthermore, it is used not only for ordinary hot water and water, but also for ON-OFF supply of liquids such as liquid soap, disinfectant, fuel, and edible oil.

的に供給開始している。FIG. 11 is an explanatory view of a conventional sensor-type automatic faucet. Here, the object immediately below the exit is detected in a non-contact manner by the infrared sensor, and when a hand is inserted directly below the exit, the solenoid valve is turned on immediately and the water for hand washing is automatically supplied. ing.

ットによって、それぞれ胴体に固定される。A water pipe and a control circuit are stored inside the body, and the control circuit includes a sensor that emits infrared rays and detects reflection from an object. The outlet end of the water pipe is fixed to the body by an outlet nut, and the inlet end is fixed to the body by a connection nut.

検知する。The control circuit is housed in a recess integrally formed inside the body, and positions the sensor in a transparent window fixed to the body. The sensor emits infrared light directly below the exit through the transparent window, and detects reflection from an object through the transparent window.

る。配管の上端は、ナットによって導水パイプに接続さ
れ、配管の下端は、ナットによって弁体に接続される。In a narrow space below the counter plate (which may be isolated from the outside by a panel or a door), an electromagnetic valve composed of a solenoid and a valve body is arranged. Here, the inlet side of the valve body is fixed to the end of the water supply pipe, and the outlet side of the valve body is connected to a pipe connected to the lower end of the body. The upper end of the pipe is connected to a water pipe by a nut, and the lower end of the pipe is connected to a valve body by a nut.

Then, the cutoff state of the valve body is switched to the water flow state.

カウンター板に取付け固定する作業と、電磁弁を給水管
に接続する作業とを別々に実施する必要がある。The sensor type automatic faucet of FIG. 11 has a problem that the installation work is relatively difficult, and the installation work requires skill and time. In addition, there is a problem that electric leakage and a hooking accident easily occur in wiring between the control circuit and the solenoid valve and in wiring connecting the control circuit to the power supply line. That is, in the sensor-type automatic faucet of FIG. 11, it is necessary to separately perform the operation of attaching and fixing the body of the sensor-type automatic faucet to the counter plate and the operation of connecting the solenoid valve to the water supply pipe.

収する必要も出てくる。Further, since the mounting of the body and the mounting of the valve body are independent, the distance and the positional relationship between the lower end of the body and the outlet of the valve body are different every construction, and the piping is made of a flexible material. In some cases, it is necessary to absorb errors in distance and positional relationship, for example, by forming them.

能性も低くない。However, even though a flexible material is adopted, the connection of the water guide pipe and the valve body by piping is performed on site, and these connections are generally made in a narrow and difficult-to-work environment such as the back side of a counter plate. Therefore, the reliability of the connection work cannot be secured, and the possibility of water leakage after construction is not low.

The power supply, the control circuit, and the solenoid valve are connected to each other by wires exposed to the outside, and these wires need to be connected on-site after piping work. Even if these wirings are simplified using a one-touch connector, the wiring exposed on the back side of the counter plate is still obstructive, and the hanging wiring hinders other operations and cleaning. In addition, due to water leakage, high humidity, or dew condensation in the piping, poor connection of the connector, electric leakage, disconnection due to corrosion, and the like may occur.

しい配管を組み立てる必要がある。In particular, when replacing a conventional manual faucet with a sensor-based automatic faucet in connection with renovation of an existing washroom or hand washing tub, a considerable portion of the piping connected to the manual faucet is renewed. Need to be replaced. In the case of the sensor type automatic faucet of FIG. 11, the water supply pipe is cut off on the back side of the counter plate, the existing pipe from the valve body to the position penetrating the counter plate is completely removed, and the valve from the valve body to the body is removed. New pipes need to be assembled.

However, since the piping is disposed below the counter plate, a sufficient installation space may not be provided, and the assembling work is often difficult.

As shown in FIG. 12, the electromagnetic valve, the outlet side conduit, the sensor and the electric circuit are integrally formed, and this is housed in a vertically divideable housing, and is provided at the end of the supply side conduit as shown in FIG. It is configured so that it can be integrally attached to it.

ある。In the sensor type automatic faucet of FIG. 12, the installation work is relatively simple, but the faucet itself becomes large because the solenoid valve is built in the housing, giving a sense of oppression to the user. In addition, since the housing can be divided into upper and lower portions, water may enter the housing from the mating surface.

ために設置できないという恐れがあった。Some conventional manual faucets are mounted on a wall (see FIG. C). When replacing the manual faucet shown in FIG. C with a sensor-type automatic faucet, it is necessary to provide an electromagnetic valve, a control circuit, and the like in addition to the sensor on the front side of the wall surface. As such a sensor-type automatic faucet for mounting on a wall surface, there is one described in Japanese Utility Model Application Laid-Open No. Hei 7-44218, which has a common specification with a sensor-type automatic faucet attached to a wash basin or the like. Therefore, since the water discharge position is farther from the wall surface than the water discharge position of the manual faucet used so far (because it is closer to the user side), the relative position is shifted from the bowl surface of the basin etc. which receives the water discharge. I will. For this reason, there is a risk that the water splash on the bowl surface becomes large, or in the worst case, the water discharge position is deviated from the bowl surface of the wash basin or the like, so that the bowl cannot be installed.

ができ、水栓をコンパクトに設計することができる。According to the present invention, the electric actuated valve for turning on and off the flow of the liquid supplied through the supply line, and the flow of the fluid turned on by the electric actuated valve is guided to the outlet to be discharged into the atmosphere. An outlet-side conduit, a sensor that detects an object inserted immediately below the outlet portion in a non-contact manner, and outputs the presence or absence of the object, and controls the electrically operated valve based on the output of the sensor. ON-OFF of the electric valve
In a sensor type automatic faucet having a control circuit for switching a state and a power supply unit for supplying electric power to the electric actuated valve, the sensor and the control circuit, a flow path from a supply side pipe to an outlet side pipe is provided therein. A flow path forming member having a space for mounting an electrically operated valve is provided between the supply side pipe and the outlet side pipe while being formed on one axis, so that the distance between the supply side pipe and the water discharge port is effectively used. As a result, the electrically operated valve can be arranged, and the faucet can be designed to be compact.

ないという現場が無くなる。Further, a water stopcock mounting portion for mounting a water stopcock for closing a flow from the supply side pipeline to the outlet side pipeline is provided below the electromagnetic valve mounting space of the flow path forming member. In this case, the distance between the supply-side conduit and the water outlet is not increased, and the water outlet position can be almost the same as that of the conventional manual faucet. This eliminates the problem of slipping out of the plane, and eliminates sites where installation is not possible.
