A clean room 100 and a separate machine room 200 of a necessary size are constructed using modules of various dimensions and shapes manufactured in advance, and the air blower 210 of the machine room 200 and the ceiling of the clean room 100 are The blower duct 220 is connected between the installed HEPA filters 110, and for this purpose, unit ducts manufactured in small sizes are connected one by one.

That is, after the air blower 210 and one end of the unit duct 220 connected to the other end of the fastening plate 222, one side of the other unit duct 220 to be connected in contact with each other, Between them, a sealing body 223 such as a sponge for sealing is inserted, and the connection between the fastening plates 222 in contact with each other is firmly connected by bolts 224, etc., and several units are connected to the HEPA filter 110. Connect the duct.

In addition, the exhaust duct 240 is connected in the same manner as described above between the diffuser 120 provided in the clean room 100 and the air exhaust device 230 of the machine room 200.

In addition, when the air blowing device 210 and the air exhaust device 230 are operated, external air is introduced into the blowing duct 220 through the air blowing device 210 and supplied to the clean room 100. At this time, the air introduced through the HEPA filter 110 installed on the ceiling of the clean room 100 is purified and supplied.

In addition, the air inside the clean room 100 is sucked into the diffuser 120 by the operation of the air exhaust device 230, and the HEPA filter 110 provided in the air exhaust device 230 through the exhaust duct 240 It is purified while passing through, and through the pre-filter 232 and the ultraviolet sterilization lamp 233, it is purified with air in a state that is not polluted and is exhausted to the atmosphere.

In addition, the wastewater discharged to the drainage pipe 341 due to the cleaning work inside the clean room 100 is accumulated in a certain space, and the accumulated wastewater is monitored by the wastewater level monitoring unit 331, and accumulated above a certain level. In this case, the drug input unit 332 is operated to inject the drug. Wastewater that has been sterilized and purified through chemical treatment is discharged to the outside of the clean room.

On the other hand, when a visitor wants to enter the clean room 100 from the outside, first, an external entrance door 310 leading to the shower room 300 to remove dust or fine particles attached to the body. For this purpose, the external door 310 is opened and closed again, and after taking a shower using an air shower installed in the shower room 300, the shower room 300 and the clean room 100 ) The interception door 320 provided between them is opened to enter the clean room, and the blocking door 320 is also closed to block the clean room 100 from communicating with the outside.

However, as described above, when the access door 310 is opened for access from the outside to the shower room 300, when the blocking door 320 is also opened, the clean room 100 cannot be maintained in a clean state. When the entrance door 310 is open, the blocking door 320 must be locked.

This detects whether the operating table 401 of the interlocking device 400, which is a solenoid valve installed on one door, is pulled out by the operation detection unit 410 such as a limit sensor, and whether the door is locked or the door is immersed to open the door. After that, when the external door 310 is opened for access as described above and detects that the operating table 401 of the interlocking device 400 is immersed, the operation control unit 420 detects that the other door is a blocking door ( The working table 401a of the interlocking device 400a installed in 320 is withdrawn so that the blocking door 320 is locked.

Therefore, when the external door 310 is open, the blocking door 320 is not opened, and when the external door 310 is closed, the operation control unit 420 by the operation detection unit 410 that senses it The interlocking device 400a of the blocking door 320 in a locked state is operated to position it in an open state.

Therefore, the blocking door 320 is in a state in which it can be opened, and when opening of the blocking door 320 is detected by the operation detection unit 410, the operation control unit 420 is By operating the interlocking device 400 installed in the locked state, when the blocking door 320 is open, the external door 310 is not opened to communicate with the clean room 100 and the outside in an unprotected state. So that there is no.

On the other hand, when the air inside the clean room 100 is sucked into the diffuser 120 by the air exhaust device 230 and discharged to the atmosphere through the exhaust duct 240, it may be discharged from the inside of the clean room 100 to the outside. Viruses, etc., are sterilized and discharged while passing through the sterilization device 500 of the present invention.

That is, when the air inside the clean room 100 flows into the phytoncide solution container 510 through the first exhaust duct 241 among the exhaust ducts 240, the sterilization unit 520 rotated by the rotating device 530 is As it passes, it is sterilized by the phytoncide solution and then discharged to the atmosphere through the second exhaust duct 242.

Looking specifically at this, the first rotating table 521 rotates while the rotating device 530 rotates, and the second rotating table 522 fitted into the fitting groove 523 of the first rotating table 521 also rotates at the same time. do. And, while the sterilization plate 525 is also rotated, it is immersed in the phytoncide solution contained in the lower portion of the phytoncide solution container 510 and then moves upward, and the sterilization plate 525 through which the contaminated air has passed is rotated and immersed in the phytoncide solution again. The process is repeated.

In addition, when the sterilizing plate 525 of the filter unit 520 is to be replaced after a certain period of operation, the second rotary table 522 is pulled out of the second shaft groove 512. As the elastic spring 526 is compressed between the second shaft groove 512 by the locking protrusion 524 formed on the second rotary table 522, the second rotary table 522 is a fitting groove of the first rotary table 521 ( 523).

Accordingly, the sterilizing plate 525 can be separated from the second rotating table 522 and drawn out to the opening and closing part 540 at the top, and the second sterilizing plate 525 is inserted into the second rotating table 522 and then pulled. When the rotating table 522 is released, the second rotating table 522 is again fitted into the fitting groove 523 of the first rotating table 521 by the elastic force of the elastic spring 526.

In this way, the sterilization device 500 of the present invention sterilizes contaminated air that can be exhausted from the clean room 100 together with the virus through the sterilization plate 525 coated with the phytoncide solution, as well as the sterilization plate 525 ), a new phytoncide solution can be automatically applied. In addition, there is an advantage in that the sterilization plate 525 can be easily combined and replaced.
