This is a continuous water dispensing device for an automatic water dispensing and water stop valve, which is characterized in that the light sensor switch circuit interrupting plate 12 is removed from the above-mentioned optical path position to enable automatic dispensing and stopping of water.

[Effect]

Since the present invention has the above-mentioned configuration, when not in use, the optical sensor switch circuit interrupting plate 12 is located outside the light emission path of the detection sensor 6 and the detection optical path of the light receiving element 5, enabling conventional automatic water supply and water stop. When using continuous water supply, the operating lever 11 of the optical sensor switch circuit interrupting plate 12 is operated to place the interrupting plate 12 on the detection optical path of either the light emitting 4 of the detection sensor 6 or the light receiving element 5. By holding the position, the detection sensor 6 detects and the solenoid valve 2 is opened under the control of the control device to automatically continue dispensing water, and when this continuous dispensing is to be stopped, the above-mentioned The operation lever 11 of the interrupter plate 12 may be moved to the non-use position to enable the faucet to automatically turn on and off the water, as in the conventional case.

〔Example〕

A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings FIGS. 1 to 3.

First, a faucet with an automatic water drain/stop valve to which the present invention is applied is shown: 1 is a water flow control valve, 2 is a solenoid valve, and 3 is a faucet body. In order to provide a water function, a detection sensor 6 consisting of a light emitting element 4 and a light receiving element 5 is housed in a casing and arranged at the discharge end of the faucet. When detected by the detection sensor 6, the electromagnetic valve 2 is opened and water is automatically discharged under the control of a control device (not shown).Conversely, when a hand or the like is removed from the detection optical path of the detection sensor 6, When the detection sensor 6 becomes non-detecting, the electromagnetic valve 2 is closed and the water is automatically stopped under the control of the control device.

In order to achieve the above object, the present invention provides a detection sensor 6 consisting of a light emitting element 4 and a light receiving element 5 housed in the faucet body 3.
By arranging the continuous water discharge plate main body 7 on the detection optical path, water can be automatically discharged continuously.

That is, the continuous water outlet plate main body 7 of this invention has a pair of supporting members 1 on the circumferential surface 9 of the water supply port 8 of the faucet main body 3.
0, and is rotatably clamped to this support member 10.

That is, to explain this example in detail, the continuous water discharge plate main body 7 has an operation lever 11 and a light sensor switch circuit interrupting plate 12 formed integrally with each other. Furthermore, this continuous water discharge plate main body 7 is attached to the faucet main body 3.
When the faucet is inserted into the water supply port 8 of the faucet, the operating lever 11 is located on the left side 13, and the optical sensor switch circuit interrupting plate 12 is located on the front side 14 of the faucet body 3. At this time, in order to accurately position the operating lever 11 and the interrupting plate 12, a notch 1 has a stopper surface 15 at a position substantially opposite to the interrupting plate 12.
6 is formed. And this stopper side 1
A stopper pin 17 that engages with the faucet body 3 is vertically provided on the lower surface 18 of the faucet body 3. And the second
In the figure, when the right side 15' of the left and right stopper surfaces 15 of the notch 16 come into contact with each other, the continuous water outlet plate is placed on the detection optical path of the light emitting element 4 located on the right side 19 of the front side 14 of the faucet main body 3. The light sensor switch interrupting plate 12 of the main body 7 is positioned.

When the left side 15' of the stopper surface 15 is in contact with the stopper pin 17 in FIG. positioned between.

Therefore, the operation lever 11 of the continuous water discharge plate main body 7
By rotating the light sensor switch in the direction of arrow Q in FIG. 2, the optical sensor switch interrupting plate 12 is similarly rotated in the direction of arrow R. As a result, the intermittent plate 12 is located on the light emitting element 4 of the detection sensor 6 attached to the lower surface 18 of the faucet main body 3, and in this example, the intermittent plate 12 allows the detection sensor to be The detection sensor 6 is configured to detect by reflecting the light from the light emitting elements 4 of 6.

Upon this detection, the solenoid valve 2 is opened under the control of the control section and water continuously flows out.

Furthermore, when not in use, that is, when there is no need for continuous water dispensing, by positioning the operating lever 11 of the continuous water dispensing plate main body 7 to the solid line position shown in FIG. It is positioned between the light emitting element 4 and the light receiving element 5 of the sensor 6. That is, the light emitting element 4 and the light receiving element 5 are positioned and held at a substantially intermediate position without coming close to the detection optical path of the light emitting element 4 and the light receiving element 5, and without affecting the detection optical path in any way.

In this embodiment, an example is shown in which the faucet main body 3 is rotatably attached. That is,
The faucet main body 3 is configured as a rotatable faucet pipe 21 connected to a rotatable joint 20 .

However, it goes without saying that this faucet main body 3 can also be used as a fixed type. Further, in this example, an example is shown in which the light sensor switch circuit interrupter plate 12 of the continuous water flow plate main body 7 functions as a reflector, but this light sensor switch circuit interrupter board 12 may be of a light-shielding type. It is also possible.

Furthermore, it is conceivable that water can flow out continuously by installing a bypass pipe and a switching valve on the conventional automatic water drain and stop valve itself; however, in this case, by installing a bypass pipe and switching valve The control device becomes complicated, and the device itself becomes large. Normally, only the minimum necessary space is secured at the installation location for this type of faucet body 3, so it is inconvenient in terms of functionality, construction, and cost. Appropriate.

As a result, the present invention has the functions of water saving and sanitary maintenance, is more space-saving, can be easily adapted to existing systems, and is easy to use during continuous water outflow. This has the unique advantage of not becoming stiff during normal use other than during normal use.

As for the power supply, safety can be improved by converting AC 100V into a constant voltage and current, for example, DC 24V and 0.5mA.

Next, an example of use of this embodiment will be explained.

First, during automatic continuous water dispensing, turn the operating lever 11 of the continuous water dispensing plate 7 disposed on the lower surface 18 of the faucet main body 3 in the direction of arrow _Q1 in FIG. When the light sensor switch circuit interrupting plate 12 of the continuous water supply plate 7 is pressed, the arrow indicates
R Rotates in _one direction. At this time, the right stopper surface 15' of the notch 16 located on the substantially opposite side of the optical sensor switch circuit interrupting plate 12, that is, on the rear side 22 of the faucet main body 3, touches the bottom surface 1 of the faucet main body 3.
The stopper pin 17 that is vertically provided at Then, the intermittent plate 12 is rotated onto the detection optical path of the light emitting element 4 located on the right side 19 of the detection sensor 6, and the cross-sectional plate 12 reflects the light on the detection optical path. When the light receiving element 5 of the detection sensor 6 detects this reflected light, a detection signal is transmitted to the control device. Upon receiving this detection signal, the control device sends a drive signal to the solenoid valve 2.

Then, the valve body 25 is driven via the solenoid 24 in the valve case 23 of the solenoid valve 2, and the return spring 26 is compressed, causing the valve body 25 to be driven.
The diaphragm 28 attached to the front end 27 of the solenoid valve 2 is displaced rearward, creating a flow path gap between the diaphragm 28 and the valve seat 29, and the water in the primary passage 30 of the solenoid valve 2 is transferred to the secondary side. Water is automatically and continuously discharged from the water supply port 8 of the faucet main body 3 via the rotary faucet pipe 21 which passes through the flow path 31 and is connected to the rotary joint 20.

Regarding the amount of water flowing out at this time, the required amount can be appropriately selected, for example, in a ratio of 1 to 10 using the water amount regulating valve 1 disposed in the primary flow path 30 of the solenoid valve 2. It's easy to do.

Also, when not in use, that is, when continuous water flow is not required, the continuous water flow plate 7 can be rotated to the non-use position, that is, to a position perpendicular to the left side 13 of the faucet body 3. can be used. That is, by placing your hand on the light emission path of the detection sensor 6 and the detection light path of the light receiving elements 4 and 5,
When the detection optical path is cut off, water is emitted, and when the detection optical path is removed, the water is automatically stopped.

Therefore, it has a water saving effect and is very useful for sanitary maintenance since there is no need to touch the knobs.

In this example, an example is shown in which the intermittent plate 12 is rotated around the light emitting element 4 of the detection sensor 6, but the same operation can be performed even when the intermittent plate 12 is rotated around the light receiving element 5. It is. As described above, although it is easy to use and has a simple structure, it is very effective during use, and furthermore, because of its simple structure, it is possible to reduce manufacturing costs.

As mentioned above, in this invention, conventional automatic water dispensing,
The good features of water stop valves include automatic water shut-off, which allows water to be turned on continuously while doing other tasks, or in case of requests such as storing water, while making use of water conservation and sanitary protection. It is possible to provide a continuous water discharge device in a faucet.

Furthermore, since the device itself can be made small and compact, it is possible to provide a means for saving space for assembly.

In addition, it has various practical advantages, such as being able to be easily assembled to existing automatic water drain and stop valves, and thus providing a means for lowering manufacturing costs.
