The present invention relates to a valve device, and more particularly to an electromagnetic sensitive valve device of a new structure capable of shortening the response time and accurate operation by having a mechanism that opens and closes the pipeline through which tap water flows.

In general, the valve device is configured to selectively open and close the flow of the fluid, such as tap water.

In particular, recently, the valve device has been used in a wide range of fields, such as being applied to a structure such that tap water can be automatically supplied when a proximity of a person or various objects is made by configuring the valve device to be interlocked with various sensitive sensors.

A representative example thereof is an electromagnetic sensitive valve device applied to a urinal, a toilet, a wash basin, a sink, a shower, and the like.

However, in the related art, only various kinds of sensitive sensors are installed in a separate housing, and the valve device is usually installed on a pipeline embedded in a wall, which makes it difficult to work for its installation and is inconvenient when the valve device is broken. There was a problem.

In addition, the conventional valve device has a problem that it takes a long time from the time of sensing the object by the electromagnetic response to the fluid discharge because of the long distance between its installation position and the discharge port through which the actual fluid is discharged. .

In addition, a conventional valve device is typically composed of a solenoid type electromagnetic valve, and a valve for selectively opening and closing a fluid line and a series of structures for operating the valve are integrally formed with each other.

Accordingly, when condensation occurs in the valve, a problem often arises in that water is transferred to the electromagnetic valve, causing a failure of the electromagnetic valve.

In addition, the valve device composed of the above-mentioned electromagnetic valve has a problem that the construction is difficult as the size is reduced, because the power consumption is relatively large, a lot of trouble may occur.

Therefore, the upper portion of the diaphragm 320 is always in a state of full water, and when water pressure is generated in the filled water, the diaphragm 320 is in a state that can be operated downward under the influence of the water pressure. The hydraulic pressure generation process mentioned here will be described later.

In addition, the diaphragm 420 selectively lifts and serves to block at least one of the first tube 510 and the second tube 520.

At this time, the diaphragm 420 is formed to be elastically deformed so that the center portion thereof is recessed into the recess groove 411 of the cap portion 410. In particular, the diaphragm 420 may be formed of a rubber material having a soft but good sealing property.

In addition, the upper cam 430 is configured so that the upper end is coupled to the diaphragm 420 to lift the diaphragm 420, the lower cam 440 is coupled to the upper cam 430 It is configured to raise and lower the upper cam 430 by the rotation operation.

At this time, along the upper circumference of the lower cam 440, an inclined jaw 441 inclined downward (or upward) toward a clockwise (or counterclockwise) direction is formed, and a circumference of the bottom of the upper cam 430 is formed. A seating jaw 431 is formed in the upper surface of the inclined jaw 441 of the lower cam 440. The bottom of the seating jaw 431 is preferably formed to form the same slope as the inclined jaw 441. Thus, when the lower cam 440 is rotated, the seating jaw 431 of the upper cam 430 is guided by the inclined jaw 441 of the lower cam 440 to raise the upper cam 430. Or, it moves downward.

In addition, the rotating unit 450 is configured to rotate the lower cam 440.

In addition, the lower housing 462 is coupled to the bottom of the upper housing 461 and is formed to surround the lower end of the rotating part 450.

Meanwhile, the drive unit 400 may apply the solenoid valve 400a as shown in FIGS. 8 and 9 in addition to the mechanical configuration described above. The solenoid valve acts to induce a pressure increase (hydraulic pressure increase) in the first tube 510 by blocking the first tube 510 and / or the second tube 520 while the plunger 401a is operated. Reference numeral 402a is a spring that pushes the plunger outward.

In addition, the first tube 510 is a conduit that induces such a high pressure when the pressure inside thereof rises to a high pressure as the end connected to the cap 410 is blocked.

In this case, one end of the first tube 510 is connected to an upper end of the cover 310 of the valve unit 300 as shown in FIG. 1 and communicates with a space inside the cover 310, and the first tube ( The other end of the 510 is connected to the cap 410 constituting the drive unit 400.

In addition, in the embodiment of the present invention, as shown in FIG. 1, a bearing part 480 supporting the coupling shaft 470 at the lower end of the upper housing 461 constituting the housing part 460 of the driving part 400 is further included. It is presented.

At this time, the spring (not shown) to elastically install the upper cam 430 to the bottom of the upper housing 461 is preferably configured to be fixed to the bearing portion 480.

In addition, the embodiment of the present invention suggests that the power supply unit 700 is further provided in the case unit 100.

Of course, a power source for driving the driving unit 400 or controlling the control unit 600 may be connected to an external power supply terminal. In this case, inconvenience in installation may occur. Accordingly, as shown in FIG. 1, the power supply 700 is most preferably configured as a separate battery.

On the other hand, in the embodiment of the present invention suggests that the sensing unit 800 for sensing the proximity of the object is further provided.

The sensing unit 800 is mounted on the front of the case unit 100, and configured to provide the sensed signal to the control unit 600 when an object is approached.

The attached FIG. 5 illustrates the circuit structure of the sensing unit 800 in more detail. Hereinafter, the structure of the sensing unit 800 will be described in detail with reference to the following.

First, an optical sensor having a light emitting unit 810 and a light receiving unit 820 is applied to the sensing unit 800.

The light emitting unit 810 is supplied with power from the power supply unit 700 to output a pulse signal, and a pulse generating unit 811, and is connected to the pulse generating unit 811, the light emitting element 813 only in the high-level section of the pulse A light emitting driver 821 for driving the light emitting unit; a light emitting element 813 emitting light of a predetermined wavelength by the light emitting driving unit 812; and a pulse generating unit 811, The bias control unit 814 outputs a bias voltage synchronized with the pulse.

In addition, the light receiving unit 820 receives light reflected by a user and converts the light into a current corresponding to the intensity of the light receiving element 821 and the voltage corresponding to the current output from the light receiving element 821. Generated by the current-voltage converter 822 for amplifying, the filter unit 823 for filtering natural light signals among the signals output from the current-voltage converter 822, and the current-voltage converter 822. The comparator 824 may recognize the presence or absence of an object by comparing the received voltage with a reference voltage.

In addition, the pulse generator 811 receives DC power from the power supply unit 700 and outputs a pulse having a small duty (pulse width / cycle). At this time, the duty of the pulse is preferably formed about 1/5100. The light emitting driver 812 is operated to emit light from the light emitting device only in a high level section of the pulse output from the pulse generator 811. The bias controller 814 generates a bias voltage synchronized with the pulse signal of the pulse generator 811 and transmits the bias voltage to the comparator 824. The comparator 824 generates a recognition signal of an object by comparing the output voltage of the filter unit 823 with a preset voltage only in a high level period of a pulse. Reference numeral 831 is an inverter configured to invert the voltage output from the comparator 824. Reference numeral 832 denotes a delay circuit, which is configured to control a signal of the inverter 831 generated due to the delay time of the light receiving element 821. Reference numeral 833 is a signal converter configured to receive a signal output from the comparator 824 and a signal output from the delay circuit 832 to output a continuous signal according to the presence or absence of an object.

In particular, the embodiment of the present invention suggests that the light emitter 810 and the light receiver 820 are composed of two or more.

In this case, the light emitting units 810 are provided to be spaced apart from each other by a predetermined interval in the vertical direction (ie, the direction perpendicular to the horizontal plane), and the light receiving units 820 are respectively disposed between the light emitting units 810. It is preferably configured to be located.

This is to ensure that the area sensed by the sensing unit 800 can be made wider in the vertical direction so that the proximity of a relatively short child can be accurately sensed.

Hereinafter, an operation process of the electromagnetic sensitive valve device according to the embodiment of the present invention will be described.

First, a state in which the proximity of the user, which is the first state, is not made is the same as those of FIGS. 2 and 6A.

That is, since the first communication hole 241 and the second communication hole 242 of the flow tube 200 is kept closed by the diaphragm 320 constituting the valve unit 300, the flow tube 200 The flow of fluid through the state is not made.

At this time, the upper cam 430 is in the state of being moved upward by the rotation operation of the lower cam 440, the diaphragm 320 located on the upper portion of the upper cam 430, the first and second tubes As the 510 and 520 are blocked, the water pressure increases as the water is blocked, especially in the interior of the first tube. therefore,

The fluid (water) inside the concave groove 411 of the cap part 410 is in a compressed state and is provided into the cover 310 of the valve part 300 through the delivery part 510. Therefore, the diaphragm 320 is to close each communication hole (241,242) while being pressurized under the influence of the water pressure.

When the user approaches the sensing unit 800 in the normal state as described above, the sensing unit 800 is sensed and the sensing signal is transmitted to the control unit 600.

At this time, in the embodiment of the present invention, since the sensing unit 800 is installed in such a manner that a plurality of light emitting units 810 and light receiving units 820 cross each other vertically, more accurate sensing of the user can be detected. have.

When the sensing signal for the proximity of the user is input to the controller 600 as described above, the controller 600 drives the driving motor 453 of the driver 400 in the forward direction (clockwise when viewed from the front). The worm gear 452 is also rotated in the forward direction by the driving of the driving motor 453.

When the worm gear 452 is rotated, the worm wheel 451 coupled to the worm gear 452 is rotated clockwise when viewed from the bottom, and is coupled to the coupling shaft 470 by the rotation of the worm wheel 451. The lower cam 440 is rotated in the direction of the arrow of Figure 6b attached.

At this time, when the lower cam 440 is rotated in the same direction as the worm wheel 451, a relatively low portion of the inclined jaw 441 formed in the lower cam 440 is a seating jaw 431 of the upper cam 430 ) And the upper cam 430 is moved downward by the restoring force of the spring (not shown). Its state is as shown in Figure 6b.

In addition, when the upper cam 430 is moved downward, the end of the first tube 510 is in an open state, so that the hydraulic pressure applied to the first tube is removed.

As a result, the inside of the valve unit 300 also restores the elastic member 330 while finding the maximum flat pressure, and then the diaphragm 320 is elastically deformed.

At this time, the diaphragm 320 is moved upward by the restoration of the resilient member 330, the central portion of the first communication hole 241 and the second communication hole 242 is closed.

Therefore, as shown in FIG. 7, the first communication hole 241 and the second communication hole 242 form an open state with each other.

In addition, the fluid supplied through the inlet 220 of the flow pipe 200 passes sequentially through the inner space of the bottom of the first communication hole 241 and the diaphragm 320 and the second communication hole 242. It is discharged through the outlet 230 of the flow pipe 200, which allows a user to use the discharged fluid (for example tap water).

The above-described series of processes continue until the user leaves the wash basin and the sensing unit 800 cannot sense the proximity of the user.

If the sensing unit 800 does not sense the proximity of the user during the above-described series of processes, the control unit 600 drives the driving motor 453 in the reverse direction (counterclockwise when viewed from the front). The worm gear 452 is also rotated in the same direction as the motor shaft of the drive motor 453 by the driving of the drive motor 453.

When the worm gear 452 is rotated, the worm wheel 451 coupled to the worm gear 452 rotates in a counterclockwise direction when viewed from the bottom, and is coupled to the coupling shaft 470 by the rotation of the worm wheel 451. The combined lower cam 440 is also rotated in the same direction as the worm wheel 451.

At this time, when the lower cam 440 is rotated in a counterclockwise direction when viewed from the bottom, a relatively high portion of the inclined jaw 441 formed on the lower cam 440 is attached to the upper cam 430 as shown in FIG. 6A. Located at the bottom of the seating jaw 431, the upper cam 430 is gradually moved upward by the lower cam 440.

In addition, the upper cam 430 moves upward to block the lower opening of the transfer unit 510, thereby increasing the pressure as the inside of the transfer unit is suddenly blocked while the water is flowing.

As the pressure rise in the delivery unit 510 presses the central portion of the diaphragm 320 constituting the valve unit 300 in the downward direction, the diaphragm 320 is connected to the flow pipe 200 as shown in FIG. 2. The first communication hole 241 and the second communication hole 242 formed in the (closed) both close, and eventually no more fluid is provided to the outlet side of the flow pipe (200).

On the other hand, the electromagnetic sensitive valve device according to the embodiment of the present invention does not always have to operate in the same state as applied to the washbasin.

That is, the urinal or the toilet may be provided with tap water when the user is away from the urinal or the toilet after work is finished.

In this case, it is more preferable that the tap water is not automatically provided to the user without being sensed, but the control is automatically stopped after a certain time.

On the other hand, when the drive unit 400 is a solenoid valve can be opened and closed by a simple method compared to the mechanical valve, the size of the drive unit can be reduced.

As described above, the electromagnetic sensitive valve device according to the present invention has various effects as follows.

First, the electromagnetic sensitive valve device according to the present invention has the effect that the overall size can be minimized by configuring the valve portion is configured by the external force instead of the electromagnetic valve.

Secondly, the electromagnetic sensitive valve device according to the present invention can minimize the size as described above, so that it can be directly installed on the pipeline without being embedded in the wall, so that the work for its installation or repair can be easily performed. Has an effect.

Third, since the distance between its installation position and the discharge port through which the actual fluid is discharged is short, the time required for the fluid to be discharged from the time of sensing the object by the electromagnetic response can be minimized. Has an effect.

Fourth, the electromagnetic sensitive valve device according to the present invention is configured so that the driving unit for operating the valve unit is formed to be separate from the valve unit, even if dew or the like in the valve unit because the water is not delivered to the drive unit The failure of the drive unit has the effect of being prevented.
