DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of a remote control type electromagnetic flash valve with a generator suitable for use in a toilet flushing device and the like. In the figure, reference numeral 10 denotes a tube of the electromagnetic flash valve, and a main water passage 12 is provided therein. have.

A valve seat 14 is provided at an intermediate position of the main water passage 12. Reference numeral 16 denotes a main valve body composed of a diaphragm. When the main valve body 16 is seated on the valve seat 14, the main water passage 12 is shut off. That is, the upstream water passage 12A and the downstream water passage 12B in the main water passage 12 are in a non-communication state. The main valve body 16 is separated upward from the valve seat 14 in the figure to open the main water passage 12, where the upstream water passage 12A
And the downstream water passage 12 </ b> B are in communication with each other, and the water flowing from the inlet 18 flows through the main water passage 12 and then flows out from the outlet 20.

A back pressure chamber 22 is formed on the back side (upper side in the figure) of the main valve body 16, and the main valve body 16 is normally seated on the valve seat 14 by the water pressure inside the back pressure chamber 22. State,
That is, the valve is kept closed. The back pressure chamber 22 can communicate with the downstream water passage 12 </ b> B through the center hole 23 of the main valve body 16, and always communicates with the upstream water passage through a small through hole provided in the main valve body 16 outside the valve seat 14. It is in communication with 12A.

The center hole 23 is normally closed by a plunger valve 30 of an electromagnetic valve, which will be described later, and the plunger valve 30 moves upward in the figure to open the valve. Is located at the downstream water channel 12B through the central hole 23.
It is in a state of communicating with.

Numeral 24 denotes an electromagnetic valve for pilot-operating the main valve element 16, which includes a solenoid coil 28 housed inside a coil casing 26, a plunger valve element 30 made of a magnetic material, a fixed core 32, and a A spring 34 for urging the plunger valve body 30 downward in the drawing, that is, in the valve closing direction, and a latch magnet for holding the plunger valve body 30 in an open state by magnetic force when the plunger valve body 30 comes to the valve opening position. 36.

The solenoid valve 24 and the main valve body 16 operate as follows. That is, the plunger valve body 30 of the solenoid valve 24 normally has the center hole 2 of the main valve body 16 as shown in FIG.
3 is closed, and in this state, the back pressure chamber 22 is closed.
The hydraulic pressure of the main valve 16 overcomes the feed water pressure to maintain the main valve body 16 in the closed state. Therefore, at this time, the main waterway 12 is in a closed state, and water does not circulate in the main waterway 12 (FIG. 2).
(I)).

In this state, when the solenoid coil 28 of the solenoid valve 24 is energized, the plunger valve body 30 held in the closed state by the urging force of the spring 34 is turned on.
It is lifted upward in FIG. 2 (II) by electromagnetic attraction. That is, the plunger valve body 30 performs a valve opening movement (FIG. 2).
(II)). The plunger valve body 30 that has reached the valve open position is held in its open state by the latch magnet 36,
Therefore, the main waterway 12 is also kept open (FIG. 3 (I
II)). Therefore, in this state, the water flowing in from the inflow port 18 flows out from the outflow port 20, and water is supplied to a predetermined target.

On the other hand, when the solenoid coil 28 is energized in the opposite direction to the above, the plunger valve body 30 held in the open state is pushed downward by electromagnetic repulsion, and the center hole is opened. 23 is closed, that is, the valve is closed. Then, the water in the upstream water passage 12A becomes the main valve body 1
6 and flows into the back pressure chamber 22 through the small hole of the back pressure chamber 22.
When the water pressure in the inside rises and reaches a certain pressure, the water pressure in the back pressure chamber 22 overcomes the supply water pressure and the main valve body 16
Is closed. Here, the main water channel 12 is shut off and the water supply is stopped (see FIG. 3 (IV)).

In FIG. 1, reference numeral 38 denotes an operation unit installed at a position separated from the main valve body 16 and the solenoid valve 24, and has an operation member 40 for manual operation. The operation member 40 has an input portion 42 for inputting an operation force, a rod-shaped portion 44 extending from the input portion 42, and a rack portion 46 provided at a tip portion thereof. A rack gear 48 is formed in the rack portion 46.

The casing 4 of the operation unit 38
Inside 7, a transmission mechanism 50 having a plurality of gears is incorporated. The transmission mechanism 50 has a gear 51 that meshes with the rack gear 48, a gear 52 that rotates integrally with the rack gear 48, and a gear 54 that meshes with the gear 52. Each transmission mechanism 50 moves the operating member 40 left and right in FIG. The rotation is converted to the rotation and transmitted to the generator 56, which causes the generator 56 to generate electricity.

The power generated by the generator 56 is stored in a power storage means, for example, a capacitor in the control unit 58, and when the charging voltage reaches a certain voltage, the power is supplied to the solenoid coil 28 of the solenoid valve 24 through a conducting wire 60. Supplied.

In this embodiment, the operating member 40 is the return spring 4
5 is always urged rightward in the figure, that is, in the backward direction. When a leftward operation force is applied to the operation member 40 and the operation member 40 moves forward to the left, the return spring 45 itself elastically deforms and accumulates energy, and is applied to the operation member 40. When the operating force is released, the operating member 40 is caused to retreat to the right in the drawing by the energy accumulated by the elastic deformation.

Next, the operation of the electromagnetic flash valve of this embodiment will be described below. In the electromagnetic flash valve of the present embodiment, as shown in FIG. 2 (I), when an operating force is applied to the input section 42 of the operating member 40 and is pushed strongly leftward in the figure, the rack gear 48, The operating force is immediately transmitted to the generator 56 through the gears 51, 52, 54, and the generator 56 is vigorously operated to generate power.

The electric power generated by the generator 56 is supplied to a control unit 58.
However, when the operating member 40 moves forward, the power is generated quickly and vigorously, so that the charging voltage to the power storage means, for example, the capacitor quickly reaches a constant voltage, and the power from the generator 56 Is quickly supplied to the solenoid coil 28 of the solenoid valve 24. As a result, as shown in FIG.
0 operates to open the valve and keeps the valve open. At the same time, the main waterway 12 is opened, and water is supplied to a predetermined object.

Next, when the operating force applied by releasing the operating member 40 is removed, the urging force of the return spring 45 elastically deformed when the operating member 40 advances as shown in FIG. The operation member 40 starts the backward movement rightward in the drawing. The retreating movement is performed by the rack gear 48, gears 51, 5
The power is transmitted to the generator 56 via the second and 54, and the generator 56 rotates in the direction opposite to the direction in which the operating member 40 moves forward to generate electric power again.

The rotational movement of the generator 56 based on the biasing force of the return spring 45 is not as fast as when the operating member 40 is pushed, but rotates slowly over time to generate electric power at a slow speed. The power generated here is gradually stored in the power storage means in the control unit 58, and when the charging voltage reaches a certain voltage, the power is supplied from the control unit 58 to the solenoid coil 28 of the solenoid valve 24,
Here, the plunger valve body 30 that has been in the open state operates to close the valve due to the electromagnetic repulsion, and the main water passage 12 is again shut off (see FIG. 3 (IV)).

FIG. 1B shows the timing of power supply to the solenoid coil 28 in the solenoid valve 24. In the figure, the first upward peak corresponds to the solenoid coil 2 performed when the operating member 40 is pressed.
8 and the downward peak afterward, the operating member 4
Numeral 0 represents a slow retreating movement over time, and represents the energization of the solenoid coil 28 performed when the electric power generated by the generator 56 reaches a predetermined electric energy.

As shown in FIG. 1B, there is a predetermined time interval between the first energization of the solenoid coil 28 and the subsequent energization for closing the plunger valve body 30. During this time, the plunger valve body 30 is kept open, and water is supplied at a flow rate corresponding to this. That is, through the electromagnetic flash valve, a predetermined amount of water (a fixed amount of water) is supplied to a predetermined object at a water supply amount corresponding to the valve opening time of the plunger valve body 30.

In the case of the electromagnetic flash valve of the present embodiment as described above, unlike the conventional one, there is no need to perform electrical wiring work for connection to a 100 V power supply, and the electromagnetic flash valve can be easily installed, and the installation cost is reduced. In addition, it is possible to make the system inexpensive and to solve the problem that the system becomes inoperable at the time of a power failure.

In addition, in the electromagnetic flash valve of this embodiment, since the electromagnetic valve 24 is kept open for a set time only by operating the operation member 40 and starting operation, the valve is automatically closed. By appropriately setting the set time, the required amount of water can be supplied and the water supply can be automatically stopped after the supply.

In the electromagnetic flash valve of this embodiment, the plunger valve body 30 of the electromagnetic valve 24 is kept open for a predetermined time by utilizing the slow power generation operation of the generator 56 by the return spring 45. With a simple configuration, the solenoid valve 24 can be kept open for a desired time.

In this embodiment, since the operation unit 38 is arranged at a position separated from the electromagnetic valve 24, the operation unit 38 is most operated regardless of the mounting position of the electromagnetic valve 24. Can be located at a suitable position.

FIG. 4 shows another embodiment of the present invention.
In this example, unlike the above-described embodiment, the solenoid valve 24 does not include a latch magnet that holds the plunger valve body 30 in the open state after the plunger valve body 30 is opened. That is, the solenoid valve 24 of this example is a non-latch type solenoid valve.

On the other hand, the operating unit 38 is
7 is similar to the above-described embodiment in that a transmission mechanism 50 having gears 51, 52, and 54 having the same configuration as above is built in. However, in this example, a clutch mechanism is provided between the gears 51 and 52. The forward movement of the operating member 40 is not transmitted to the gear 52, that is, to the generator 56, and only the backward movement of the operating member 40 by the return spring 45 is transmitted through the clutch mechanism 62 to the gears 52 and 54. , And further transmitted to the generator 56.

The clutch mechanism 62 can be configured, for example, as shown in FIG. In the figure, 64 is the clutch mechanism 6
The rotor of FIG. 2 has an engagement claw 66 at each end. On the other hand, engagement teeth 68 are formed on the gear 52 side.

In the case of this clutch mechanism 62, the rotor 64
Gear but when rotating in FIG 5 (B) in the arrow P ₂ direction together with the gear 51, so the engaging claw 66 and the engaging teeth 68 are disengaged, the forward movement in the drawing of the operating member 40 leftward 5
2 and the rotor 6 as shown in FIG.
Only when the 4 rotates in the arrow P ₁ direction, and the engaging claw 66 and the engaging teeth 68 becomes engaged to transmit the rotational movement of the arrow P ₁ the direction of the gear 51 to the gear 52. That is, the clutch mechanism 62 does not transmit the forward movement of the operation member 40 to the generator 56, but transmits only the backward movement to the generator 56, thereby causing the generator 56 to generate power.

In the case of the electromagnetic flash valve of this example, when the operating member 40 is pushed leftward in the figure from the initial state shown in FIG.
Rotates idly, and the generator 56 does not perform the power generation operation. After the operating member 40 is pushed to the forward end (see FIG. 6 (II)), the operating member 40 is released by the biasing force of the return spring 45.
Begins retreating. At this time, as shown in FIG. 7 (III), the generator 56 rotates slowly to generate electric power.

The generated power is supplied to the solenoid valve 24,
The plunger valve body 30 in the valve closed state performs the valve opening movement. The generator 56 continues to perform power generation for a certain period of time with the slow retreat of the operation member 40, and during this time, the plunger valve 30 is kept in the open state (see FIG. 4B).

When the operating member 40 returns to the substantially initial position, the power generation of the generator 56 is stopped. Here, the plunger valve 30 is closed by the urging force of the spring 34 for urging the valve in the valve closing direction. Then, the main waterway 12 is shut off here. That is, the water supply stops.

As described above, in the present embodiment, the power supply from the generator 56 to the solenoid valve 24 is continued for a predetermined time during the backward movement of the operation member 40. As a result, the solenoid valve 24 is kept open for the set time. Even in the electromagnetic flash valve of this embodiment, the electromagnetic valve 24 can be kept open for a desired time with a simple configuration, and the water supply can be continued for the desired time and then automatically stopped. it can.

FIG. 8 shows still another embodiment of the present invention. Also in this example, the solenoid valve 24 is of a non-latch type having no latch magnet similarly to the second embodiment (the embodiment of FIG. 4). On the other hand, the operating member 40 of the operating section unit 38 is a lever type that rotates around a shaft 64, and a gear 68 is fixed to the tip of the operating member 40 inside the casing 47 so as to be integrally rotated. I have.

In this example, too, the clutch mechanism 62 is interposed between the gears 51 and 52, and the operating member 40
Only during the downward pivoting movement, i.e., the forward rotating movement, the movement is transmitted to the generator 56 via the transmission mechanism 50, and the return movement is interposed between the gears 51 and 52. It is not transmitted by the clutch mechanism 62.

In this embodiment, a flywheel 70 as an inertia member is provided so as to rotate integrally with the gear 52. In the case of this example, when the lever-type operation member 40 is pressed down in the figure, the movement is transmitted to the generator 56, and the generator 56 operates to generate power.

In this example, even if the operation force on the operation member 40 is removed, the flywheel 70 continues to rotate by the inertial force thereafter, and the generator 56 continues to generate electricity for a certain period of time. In the meantime, power supply to the solenoid coil 28 of the solenoid valve 24 is continued, and the plunger valve 3
0 holds the valve open state.

When the inertia force of the flywheel 70 is lost and the flywheel 70 stops moving, the generator 56 stops generating power and the power supply to the solenoid coil 28 stops. Here, the plunger valve body 30 of the solenoid valve 24 operates again to close the main water passage 12.

Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention can be configured in variously modified forms without departing from the gist of the present invention.
