And should not be construed as limited to the embodiments described herein.

Since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein.

It should be understood that the embodiments according to the concept of the present invention are not limited to the particular mode of disclosure but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The present invention utilizes the same as the above-mentioned Japanese Patent Application No. 0667047. Therefore, all the features of the device configuration described below can be understood as the matters described in Japanese Patent No. 0667047. [

However, the present invention is not limited to the structure disclosed in the above-mentioned '0667047', the 'construction of a switchboard and an automatic control panel to prevent the removal and inflow of moisture and corrosive noxious gas' And the structure for automatically removing the moisture contained in the outside air by heating the outside air flowing into the control panel and the operation explanation thereof are further included, and this part is the most important constitutional feature Respectively.

Therefore, the device structure, characteristics, and operation relationship described below will be incorporated by reference in the above-mentioned Japanese Patent No. 0667047, and the structure related to the main features of the present invention will be described in detail at the rear end.

1 to 3, the structure of a switchboard and an automatic control panel for preventing the removal and inflow of moisture and corrosive noxious gas according to the present invention includes a switchboard and an automatic control panel (hereinafter referred to as "control panel") 100 An external air inlet 113 and an internal air outlet 117 are formed in the external air inlet 113. The air circulator 110 is formed in the external air inlet 113 to remove moisture and corrosive noxious gas from the air introduced from the outside, ).

The air circulation device 110 is connected to the external air inlet 113 and is connected to the external air inlet 113. The air inlet 113a of the air circulation device 110 and the dust- 113b are provided so that the amount of air introduced from the outside can be adjusted by the air inflow amount adjusting opening 113a and the dust contained in the outside air can be removed by the dustproof filter 113b.

The dustproof filter 113b functions to prevent the air inside from escaping through the external air inlet 113.

The outside air introduced through the air inflow amount controlling part 113a and the dustproof filter 113b is forcibly sucked by the fan 116 installed inside the case of the air circulating device 110 and is sucked by the desiccant 114 and the harmful gas decomposition And passes through the filter 115.

Thus, the moisture contained in the outside air and the corrosive noxious gas can be supplied to the inside of the control panel 100 in a state of being removed.

At this time, the reverse air flow prevention valve 118 is installed in the inner air outlet 117 installed to discharge the hot air inside the control panel 100 to the outside so that when the air pressure inside the control panel 100 becomes higher than the atmospheric pressure, do.

This is because outside air can not be introduced into the control panel 100 if the air pressure inside the control panel 100 becomes higher than the atmospheric pressure.

The backflow prevention valve 118 may be variously attempted. However, in the present invention, the blocking plate 118b, which is rotatable by the shaft 118a, has a structure in which the inner air outlet is blocked with a slight inclination.

That is, in the state that the blocking plate 118b closes the inner air outlet 117 due to the self-load, the backflow prevention valve 118 becomes higher than the outer air pressure so that the load of the blocking plate 118b The blocking plate 118b is opened and the inner air is discharged to the outside.

According to the operation of the air circulation device 110, the outside air flows into the control panel 100, but the inside air is not discharged until a pressure capable of pushing the blocking plate 118b of the backflow prevention valve 118 is formed The air pressure inside the control panel 100 is maintained at a pressure higher than the atmospheric pressure.

Therefore, if the air pressure inside the control panel 100 is kept higher than the atmospheric pressure, the outside air containing moisture or corrosive noxious gas can not easily flow into the control panel 100, and the inside of the control panel 100 is dried And maintain a clean state.

However, when the operator opens the door of the control panel 100 for the work, the outside air does not pass through the air circulation device 110 but flows into the inside thereof, thereby becoming harmful to the internal contacts and the instrument.

Accordingly, in this case, the air circulation apparatus 110 is operated. However, the air inside the control panel 100 is sucked into the case 111 by forced suction of the fan 116. [

The sucked internal air passes through the moisture absorbent 114 and the noxious gas decomposition filter 115 to remove moisture and corrosive noxious gas.

The inside air of the control panel 100 flows through the inner air inlet 112 which is pierced between the desiccant 114 of the case 111 and the noxious gas decomposition filter 115.

The air circulation device 110 may be selectively driven by installing a door openness detection sensor, a noxious gas concentration measurement sensor, a humidity sensor, a temperature sensor, and the like in the control panel 100.

In addition, when the measured value of the sensor is equal to or greater than a reference value set by the operator, the air circulation apparatus 110 can be automatically operated for a predetermined period of time.

At this time, a control unit (not shown) may be provided to allow the sensor and the air circulation unit 110 to operate for a predetermined time.

In the present invention, the desiccant 114 and the noxious gas decomposition filter 115 are preferably formed inside the case 111 so as to be replaceable.

For this purpose, the moisture absorbent 114 and the noxious gas decomposition filter 115 may be housed in a housing and separated and combined by a hinged type.

As the moisture absorbent used for removing the moisture, various components may be used, but it is preferable to use calcium chloride which is inexpensive and has a good moisture removing effect. Of course, the moisture absorbent may be replaced with a filter for removing moisture.

The noxious gas decomposition filter 115 may also include a variety of components. The most commonly used activated carbon powder may be used, or glauconite powder, vermiculite (mica) powder, etc. may be selectively used, or a mixture of two or more thereof may be used .

4 to 5, the present invention includes a drying unit 120 for removing moisture contained in outside air by heating external air introduced into the control panel 100, The construction of the induction unit 130 for guiding the outside air introduced through the circulation unit 110 to the drying unit 120 is further realized.

The induction unit 130 includes a housing 131 having a lower end portion connected to the air circulation unit 110 and having a discharge port 131a through which the outside air is drawn inward and the outside air drawn into the upper end is discharged, A plurality of inlet holes 132a are formed in the lower inner circumferential surface of the housing 131 to allow the outside air drawn from the air circulating apparatus 110 to be dispersed and drawn into the housing 131, An opening and closing cap 133 for opening and closing the outlet 131a and a lower end connected to the plate 132 and an upper end extending to the outside of the housing 131, And a guide bar 134 formed on the guide bar 134.

The drying unit 120 includes an outer heat generating ring 121 coupled to an inner circumferential surface of the housing 131 and generating heat in response to external power supply, An inner heat generating ring 122 which is coupled to the outside of the guide bar 134 and generates heat according to the supply of power from the outside and forms a drying space 123 between the outer heat generating rings 121, And is lifted and lowered by the pressure of external air passing through the drying space 123 while being opened and closed by the guide bar 134 so as to be positioned above the generating ring 121 And includes an opening / closing plate (124).

The inner and outer heat generating rings 122 and 121 may be made of a heater and may be heated to a predetermined temperature according to the supply of power from the outside to remove moisture contained in the outside air.

The temperature at which the inner and outer heat generating rings 122 and 121 heat the outside air is preferably such that the moisture contained in the outside air can be removed.

The inner and outer heat generating rings 122 and 121 are separated from each other to form the drying space 123 through which the outside air passes.

Accordingly, the inner and outer heat generating rings 122 and 121 can contact the outside air drawn into the inside of the housing 131 and allow the outside air to pass therethrough, so that the moisture contained in the outside air can be removed through the heating of the outside air .

It is preferable that the outer heat generating ring 121 is positioned on the same horizontal line as the upper portion of the inner heat generating ring 122 and the lower portion is formed extending downward from the inner heat generating ring 122.

This is to allow the outside air flowing into the drying space 123 to be in thermal contact with the inside heat generating ring 122 together with the outside heat generating ring 121.

The opening and closing plate 124 is coupled to the guide bar 134 so as to be movable upward and downward while a hollow 124a passing through the opening and closing plate 124 is vertically formed.

The opening and closing plate 124 is lifted and lowered by pressurizing external air passing through the drying space 123 with a predetermined weight and is heated and cooled by the heat generated by the inside and outside heat generating rings 122 and 121 forming the drying space 123 So that the contact can be smoothly performed.

 In addition, the opening and closing plate 124 is heated by contact with the inner and outer heat generating rings 122 and 121 so that external air can be contacted and heated and dried.

The lower portion of the housing 131 is connected to the upper portion of the case 111, and the external air sucked from the outside through the fan 116 is discharged from the inside As shown in FIG.

That is, the housing 131 can be heated by the inner and outer heat generating rings 121 and 122 while the outside air drawn in accordance with the driving of the air circulating apparatus 110 is stored.

This allows the outside air passing through the air circulation device 110 to smoothly contact the inside and outside heat generating rings 121 and 122 so that the moisture contained in the outside air can be effectively removed.

The plate 132 is connected to a lower inner circumferential surface of the housing 131 and allows external air to be dispersed through the plurality of inlet holes 132a to be drawn into the housing 131. [

The opening and closing cap 133 has a conical shape or a truncated cone shape having a smaller diameter from the upper portion to the lower portion and is coupled to the guide bar 134 so as to be raised and lowered while a guide hole 133a penetrating in the vertical direction is formed .

The discharge port 131a preferably has the same diameter as the center of the opening / closing cap 133, and keeps the opened state when the opening / closing cap 133 is seated.

The opening / closing cap 133 is mounted on the periphery of the discharge port 131a so that the discharge port 131a is maintained in a closed state by its own load.

The opening and closing cap 133 is lifted and lowered as the internal pressure of the housing 131 is expanded due to the heating of the inner and outer heat generating rings 122 and 121 as the fan 116 is driven, So that outside air can be discharged.

The opening / closing cap 133 may be formed with a curved surface groove 133b which is depressed upward.

The curved groove 133b is formed in the housing 131 so as to be recirculated downward while being in contact with the outside air flowing upward from the inside of the housing 131 so that repeated contact with the inside and outside heat generating rings 121, So that removal can be effected effectively.

In addition, the curved groove 133b is formed so as to effectively pressurize the opening / closing cap 133 due to gathering of outside air flowing in the upward direction.

The opening and closing cap 133 may have a nonwoven fabric 135 on the lower surface thereof.

The nonwoven fabric 135 is compressed between the periphery of the discharge port 131a and the opening / closing cap 133 while the discharge port 131a is closed, thereby sealing the space between them.

The non-woven fabric 135 is in contact with external air discharged through the discharge port 131a in a state where the discharge port 131a is opened, so that the moisture contained in the external air can be absorbed and removed.

The guide bar 134 is made of metal and is heated by the heating rings 121 and 122 to be heated.

The guide bar 134 is formed with a flange 134a protruding outward at an upper end thereof and the guide part 130 is connected to the guide bar 134 so as to be positioned between the flange 134a and the opening / And may further include a spring 136 coupled thereto.

The opening / closing cap 133 may be formed with a locking groove 133c which is depressed downward at an upper portion thereof and into which a lower portion of the spring 136 is inserted.

This is to cope with the internal temperature of the control panel 100 in accordance with seasonal changes and the like.

The spring 136 presses the opening and closing cap 133 to prevent the opening and closing cap 133 from moving up and down the internal pressure of the housing 131 under a predetermined pressure.

The guide bar 134 may have threads formed on the outer circumferential surface thereof and the flange 134a may be threadably engaged with the guide bar 134 while being threaded on the inner circumferential surface thereof.

This is to adjust the elastic force of the spring 136 in accordance with the rising and falling of the flange 134a.

The opening / closing cap 133 or the spring 136 may be provided with a pressure control valve 140 for lowering the internal pressure of the housing 131 to a predetermined pressure when the internal pressure of the housing 131 increases beyond a predetermined pressure.
