Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the present invention is introduced into the case 10 and the case 10 is provided with an intake fan 11 to allow the electronic module and the outside air to be sucked into the interior as shown in FIG. It is composed of a moisture proof dustproofer 20 installed therein to remove moisture and foreign matter in the air.

The case 10 has one side open so that the outside air can be sucked into the moistureproof dustproof machine 20 by the operation of the intake fan 11, and the intake fan 11 operated by the driving of the motor is the case 10. ) It is installed on the wall.

The moisture-proof dust isolator 20 is formed with a suction hole (21a) for sucking the outside air into the inside and the exhaust hole (21b) for cooling the internal heat by exhausting the sucked air into the case, respectively.

In addition, a passage 21c is formed in communication with the suction hole 21a and the exhaust hole 21b formed in the moisture proof dustproofer 20 to allow external air to pass therethrough.

In order to form the passage 21c in the moisture proof dustproofer 20, a plurality of partitions 21 are arranged at regular intervals to serve as partitions of the moisture proof dustproofer 20, and the partition 21 is suctioned. The passage 21c is formed to communicate with the zigzag multi-stage so that air can move smoothly from the ball 21a to the exhaust hole 21b.

If the partition wall 21 is an ordinary computer case 10 as an example, the number of partition walls 21 to be applied at this time is preferably about 2 to 4 pieces.

Naturally, as the number of the partitions 21 increases, the moisture and foreign matters of the external air passing through the partitions 21 will also decrease further into the case 10.

However, since the suction force of the intake fan 11 inside the case 10 also increases as the partition wall 21 increases, it is preferable to use an appropriate number of partition walls 21.

The dampproof dustproof device 20 is disposed such that the suction hole 21a is exposed to the outside on one open side of the case 10.

The dampproof dustproof device 20 formed as described above is limited in movement as moisture and foreign matter contained in the air come into contact with the partition wall 21, so that a considerable amount of moisture and foreign matter can be exhausted in a reduced state.

Furthermore, a plurality of blocking members 22 protrude in the direction of the passage 21c on one surface or both surfaces of the partition wall 21 and repeatedly arranged at regular intervals, thereby preventing moisture and foreign matter from the air introduced into the moisture proof dustproofer 20. The barrier rib 21 is configured to be further removed.

The blocking member 22 may be vertically formed in a plane, or may be formed in a plane in front of a direction in which air flows, and may have a predetermined gap between the blocking plate 22a and the blocking plate 22a for blocking moisture and foreign matter. It is composed of a guide plate 22b spaced apart.

Here, the guide plate 22b is formed in an inclined or curved surface to form a dust collecting space 22c communicating with the passage 21c between the blocking plate 22a and the guide plate 22b, and the guide plate 22b. By protruding the front end more than the front end of the blocking plate 22a to form an inlet opened in the air traveling direction, the advancing air is introduced into the inlet to collect moisture and foreign matter in the dust collecting space 22c.

As described above, when the guide plate 22b is formed in the blocking member 22, moisture and foreign matters in the air in contact with the blocking plate 22a are removed, and then moved to another blocking member 22 located at the rear. Moisture and foreign matter gathered in the blocking member 22 by the vortex to move again, the guide plate 22b guides the air flow to suppress the vortex phenomenon, thereby preventing the scattering of dust and foreign matter collected. It can be.

Alternatively, as shown in FIG. 4, the blocking member 22 may form a blocking surface 22d having a planar front in a direction in which air travels on both side surfaces thereof, so as to suppress the vortex as described above. The rear side may be integrally formed with a guide surface 22e formed of an inclined or curved surface that gradually increases in width toward the partition wall 21.

2 and 3, the plurality of blocking members 22 may be formed to protrude to a predetermined length from the partition wall 21, and the partition wall 21 may be used to more effectively block moisture and foreign matter by increasing a volume contacting the air. It may be formed to protrude toward the passage (21c) gradually from the front to the rear of the.

That is, the ends of the plurality of blocking members 22 are gradually projected to one partition wall 21 so as to be inclined when the ends thereof are connected by an imaginary line. The front corresponding to the direction is repeatedly formed in the same structure in each partition wall 21 in a state where the width is narrow and gradually wider toward the rear.

As described above, the blocking member 22 gradually protruding may have a large amount of air moving in contact with the plurality of blocking plates 22 by a different sized volume, and a dust collecting space formed in each of the blocking members 22. Since the inlet of (22c) is all exposed in the air traveling direction, the inflow of air is easy, and the effect of blocking moisture and foreign matters is improved.

Meanwhile, as shown in FIG. 5, the moisture absorbing dustproofer 20 may include an absorbing member 30 mounted by a coating or adhesive method to more effectively absorb and remove moisture or foreign matter. 30 may be used, such as cotton fiber or sponge.

The absorbing member 30 may be mounted on the partition wall 21 and the blocking member 22 as a whole, and may be mounted on any one surface of the partition wall 21 and the blocking member 22 according to utilization. In the illustrated example, the absorbing member 30 is mounted on the surface of the partition wall 21.

Here, as shown in Figure 6, in order to improve the absorption of the absorbing member 30, the vent hole 40 is formed in the partition 21 or the blocking member 22, the absorbing member 30 on the outside Is fitted.

As described above, when the vent hole 40 is formed, the absorbing member 30 in which the vent hole 40 is positioned may absorb moisture and foreign matters more strongly than the distant portion of the passage 21c by the suction force generated in the intake fan 11. It is.

The vent 40 may be variously formed from about 1 mm to about 10 mm, and may further block moisture through such a configuration.

On the other hand, the moisture-proof dustproof dust 20 may be integrally molded into the case 10, as shown in Figure 7, the difficulty of manufacturing and to be installed in the case 10 used in the case ( 10) It can also be detachable from the inside.

As described above, in order to enable the moisture proof dustproof machine 20 to be detachable from the case 10, the case 10 may be coupled using a fastening means such as a case 10 and a bolt, and preferably a guide jaw on the inner surface of the case 10. (12) may be formed, and the moisture proof dustproof machine 20 may be fitted inside the guide jaw 12.

In addition, the moisture-proof dustproof device 20 may be configured in two or more places as well as any one of the case 10 according to the degree of internal heat generation of the case 10.

Looking at the operation of the present invention configured as described above are as follows.

First, the power source of the electronic module installed in the case 10 is connected and operated. At this time, the intake fan 11 mounted in the case 10 also rotates by driving of the motor.

The outside air is sucked into the moisture proof dust collector 20 through the suction hole 21a by the rotation of the intake fan 11, and the sucked air is first removed by the partition wall 21.

Subsequently, the air moving through the passage 21c is exhausted into the case 10 through the exhaust hole 21b in a state in which moisture and foreign matter are removed secondly by the barrier member 21 following the partition wall 21. will be.

Afterwards, the moisture and foreign matters collected in the moisture proof dustproofer 20 may be removed by removing the moisture proof dustproofer 20 from the case and sucking the foreign matter with a vacuum cleaner or by flowing clean water into the passage 21c.
