尚、禁止時間1を設The present invention relates to an automatic faucet that automatically controls the start and stop of water supply based on the detection of a human body by a sensing section. Conventionally, various structures have been known for this automatic faucet. For example, use is detected by manually blocking the optical path of a photoelectric transistor, and the optical path is blocked during the sensing. In the case of the one disclosed in Japanese Patent Publication No. 37-937, where the water supply continues while the optical path is being shut off, and the water supply stops when the optical path is removed, or after the optical path to the photoelectric transistor is interrupted and water is supplied, the water supply continues even after the interruption is removed. There is a device disclosed in Japanese Utility Model Publication No. 16196/1983, in which the light path is interrupted again to stop the water, and after the water has been stopped, the water stop is continued even if the interruption is removed. In all of these conventional systems, the valve in the water supply part opens and closes at the same time as the detection No. 19 occurs and disappears, and there is no intention to use the automatic faucet (even if the sensing part momentarily senses a human body, the water supply valve opens and closes immediately). If water starts flowing or the human body detection of the sensor unit momentarily disappears even though there is no intention to stop the water supply from the automatic faucet, malfunctions occur such as the water supply stopping and overturning. The technical problem lies in ignoring the instantaneous generation and extinction states of sensing signals.The present invention has been developed to achieve the above technical problem by providing a sensing unit that senses the human body. a control unit that generates an output based on the sensing signal; a drive unit that receives the output from the control unit; and a water supply unit that is operated by the drive unit and supplies water to the faucet; The control section generates a sensing signal and does not accept the sensing signal unless this generated state continues for a predetermined time interval, and the sensing signal disappears and the sensing signal is not accepted unless this disappeared state continues for a predetermined delay time. A malfunction prevention circuit is provided to prevent the disappearance from being transmitted to the next person.The sensing section senses the human body, sends a signal to the control section, and the control section drives the C drive section based on this signal to operate the water supply section. However, if the sensing state of the sensing section does not continue for a predetermined screening time, the sensing signal will be ignored, and if the state in which the sensing signal disappears does not continue for a predetermined delay time, the sensing signal will disappear. The instantaneous state of generation or disappearance of the sensing signal is ignored and the water supply is not started or stopped without being considered as the intention of the user. Since the present invention has the above configuration, the following is explained below. ■ When the automatic water faucet of the present invention is installed in a hand wash basin for hand washing, the C sensing section stops sensing when the user finishes washing his hands (after a predetermined selection time, the water supply stops). Since the machine stops, the dirt attached to the hand wash can be washed away and the hand wash can be kept clean, making it hygienic. ■ A sorting time and a delay time are provided to prevent the human body from leaving the sensing area while water is being supplied. Sensation may disappear (also,
This instantaneous disappearance of sensing and re-sensing will stop the water supply, and prevent the water supply from repeatedly starting and stopping frequently. It is possible to measure sex. An example of the implementation of the present invention will be described below with reference to the drawings. In this example, an automatic faucet is used for hand washing.

The main body part (5) and the drive part (C) integrally installed therein are housed in the case (7). (There is. In case (7), there is also a later system 'ra ill (
A control section (b) is electrically connected to the driving section (C) and the sensing section (a), and is also connected to the power source (18). In the case of this embodiment, the sensing section (a) includes a light emitter (19) and a light receiver (20), and infrared light from the light emitter (19) hits a human body, for example, a hand, and is diffusely reflected, and this reflected light is received. The so-called diffuse reflection type infrared photoelectric sensor (20) senses when the light is received. 3) is installed in the front part of the body (3a). That is, the sensing part <a) is fitted into the mounting hole (21) formed on the front surface of the body (3a) of the water discharging tool (3), and the cord (

Behind the valve body (13), a pressure chamber (28) is formed which is constantly in communication with the next side of the flow path through a small hole (27) bored in the peripheral edge of the valve body (13). , the pressure chamber (28) is connected to the secondary side of the flow path via the pipe L1 hole (29).
The plunge p-(23) is constantly biased by a spring (not shown) in the direction of closing the valve seat (12) at the valve body 13), and the plunge p-(
23> The pilot hole (29) is closed at the tip. Then, in this driving part (Ω), one lanshier (23) moves forward and backward by controlling the energization of the electromagnetic coil l\ by the control part (1)), and when it is pulled, the spring Press the valve body (13) with the force of the valve seat (12)

In the above embodiment, when you put your hand into the handwash basin (1), it automatically senses this and starts supplying water regardless of whether or not you have the intention to perform C1 handwashing. Needless to say, it is also possible to adopt a system that can be called an intention-sensing method, which senses the intention to wash hands and supplies C water only when the person has the intention to wash their hands. will be explained below as a second example,
A sensing part (a) consisting of an infrared photoelectric sensor, etc. is attached to the building wall (2) near the washbasin (1) as shown in Figure 7, and a control part (b) is attached to the beginning of the sensing part (a). When detected, the drive track section (C) is energized to open the water supply section (d), and when the next detection is detected, the drive section (+1'\) is de-energized and the valve is closed. The block diagram is shown in FIG. occurs, and is retold at the next rising edge of the start signal.
A bistable multi-bin/lator circuit (b-!i) that stops the generation of the C output signal, and a two-way signal that starts from the start of the output signal generation (time) after the prohibition time T, generates the output signal A timer circuit that rets when it disappears (
