Description

Bi-directional switch valve device of a mote removing device panel

The present invention induces the supply of air to the appropriate piping line among the constituent members of the LCD and PDP panel vibration suppression system, as well as to open and close more effectively, and also to forcibly introduce external cold air into the fan drive motor that generates high heat. Cooling as well as the internal high temperature is released to the outside to prevent the overheating of the motor with the bidirectional switching valve to induce appropriate switching in each direction necessary.

LCD, PDP panel damping device generates air of a certain pressure, and then moves and circulates the air to simultaneously discharge (P) and intake (V) on the upper and lower surfaces of the panel through the discharge and intake ports. It is a device that can easily remove and remove fine dust, dust and other foreign substances that are seated on the panel during the process of moving the production process of producing panels such as PDP, and further promote the perfect clean maintenance of the panel.

However, the above conventional vibration damping device is equipped with the basic air circulation function necessary to simultaneously perform the air injection and suction as described above, but does not become an effective air circulation, as well as non-operation such as pausing the air injection and suction There is a significant problem such as overheating of the fan drive motor due to irrationality of the air circulation, such as inadequate air circulation control, or failure and severe functioning due to a load.

This problem is caused by a problem that the air generated in the air piping line installed in the vibration suppression system is not effectively circulated or automatically controlled.

On the other hand, the fan-driven motor for air production installed on one side of the air piping line in the vibration suppression system is not only a heavy weight, but also expensive, which leads to enormous losses when it is frequently broken or unusable. The loss of is also inevitable.

And fan driving motors, which are usually installed in panel damping devices such as LCDs and PDPs, generate considerable heat during operation, and if the heat is not circulated and cooled in a timely manner, the cumulative failures occur or the lifespan is abruptly shortened. In case of overheating, it causes problems such as incapacity and induces cold air at all times even during non-operation. If the non-driving system repeatedly circulates only in the state in which the exhaust port and the intake port of the fan driving motor communicate with each other without introducing or exhausting outside air, the generated high temperature is drawn into the inlet of the motor as it is from the exhaust port of the motor. As it is repeatedly circulated to heat of higher temperature, if it lasts for a long time, the damage to the motor is inevitable.

In addition, the irrationality of the air circulation impedes a stable and uniform air supply / suction, thus causing an imperfection in the function of the vibration suppression device such as the removal efficiency of foreign matter on the panel.

Accordingly, in the present invention, the fan drive motor is not only operated during the vibration suppression operation in which the air is injected (P) and the suction (V) but also during non-operation (the fan drive motor is being rotated) while the injection (P) and the suction (V) are suspended. B. It was completed as a technical task with the focus on providing a bidirectional switching valve device that enables smoother and more effective air circulation and air conditioning control without absolute overheating and pressure load.

In order to achieve the above technical problem, the present invention will be described in detail with reference to the accompanying drawings.

Directional valve 300 of the present invention is divided into the inlet side 310 and the exhaust side 320, as shown in the detailed view shown in FIG.

The inlet port 311 is formed on the suction side 310, and the inlet port 321 is formed on the exhaust side 320, respectively.

At one end of the exhaust port 320, the inlet 321 is provided with a circulating air supply inlet 322 through which the outside air is introduced through the circulating air supply valve 120, while the front end of the outlet 311 is circulated. A circulating air supply exhaust pipe 312 for discharging air to the outside through the exhaust valve 130 is formed,

An air inlet port at one side of the outlet port 311 of the suction side 310 allows the air sucked from the head 200 of the vibration suppression device 220 to be introduced into the body via the air connection pipe 240. 313 is provided on the one side of the inlet 321 of the exhaust side 320, each of the air output port 323 to allow air to be supplied to the vacuum injection device 210 of the vibration suppression head 200 Formed,

The valve body may be connected between the outlet 311 and the air inlet 313 between the outlet 311 and the air inlet 313 of the inlet side 310 of the valve body, or may be blocked if necessary, as well as the valve body. While installing an opening and closing valve 1 (330) that can selectively control the communication / blocking between the internal suction side 310 and the exhaust side 320,

Opening / closing operation of a piston type to communicate between the inlet 321 and the air output port 323 or to cut off if necessary between the inlet 321 and the air output port 323 of the exhaust body 320 inside the valve body. The valve 2 350 is axially installed on the opening / closing operation rod 370 which is operated at a predetermined width by the operation of the cylinder 360.

The bidirectional switching valve 300 configured as described above has an opening / closing valve 1 (340) in operation of the cylinder 260 during the vibration suppression operation, and the body side exhaust side 310 and the suction side 320 of the bidirectional switching valve 300. Since the air is automatically cut off the middle portion of the fan driving motor 100 through the exhaust port 102 of the fan driving motor 100 through the inlet 321 of the bi-directional switching valve 300, the valve body While passing through the air output port 323 of the one side that is introduced into and communicates with the air injection device 210 of the head portion 200, the air of a predetermined pressure is exhausted,

At the other side inlet port 101 of the fan drive motor 100 exhaust port 102, the air injected from the injector 210 of the head part 200 is eliminated as the suction force corresponding to the exhaust is generated. The foreign substances such as dust and the like are collected by suction by the air suction device 220 of the head part 200 provided on one side of the injection device 210, and then pass through the connection pipe 240 and the line filter 260 for removing the foreign matter. By entering the inside of the valve body through the air inlet 313 of the bi-directional switching valve 100, and through the inlet port 311 of the communication side again flows into the inlet 101 of the fan drive motor 100 by smooth air Circulation can be planned.

In addition, the opening and closing valve 1 (340) during the non-operation (fan drive motor is in operation) in the state in which the injection and suction is suspended in the injection device 210 / suction device 220 of the vibration damper head 200. Is blocked between the inlet 321 of the exhaust side 320 and the air output port 323, the opening and closing valve 2 (350) is automatically between the outlet 311 and the air inlet 313 of the suction side (310) As the respective blocks, the passages leading to the injection device 210 and the suction device 220 of the vibration suppression head 200 on the bidirectional switching valve 300 are completely blocked. However, only the exhaust port 102 and the suction port 101 of the fan driving motor 100 can be circulated in both directions, and each cylinder 124a of the circulating air supply valve 120 and the circulating exhaust valve 130 respectively provided at the side ends thereof is operated. By rotating the supercharge fan 123 and the exhaust fan 133, the internal high temperature air is forced to be discharged to the outside, and the external air is forced to flow to cool the high temperature generated by the motor 100. By minimizing the damage to the expensive motor 100 that can be generated by the accumulation of high temperature or overheating.

As described above, the bidirectional switching valve of the present invention promotes smooth air circulation from the fan driving motor to the head unit injector and the suction device during the damping operation, as well as the state in which the air supply and the suction are blocked by the head unit injector and the suction device. Efficient open / close operation of the directional valve even during non-operation, prevents the motor load by circulating air between the exhaust and intake ports of the fan drive motor, and forcibly releases the high temperature generated from the motor by the circulation supply valve and the circulation exhaust valve to the outside. On the other hand, the external cold air is a very useful invention to provide an automatic control bidirectional switching valve that can minimize the damage of the motor that can be caused by the high heat flowing into the inside to cool the motor.
