Both ends of the supply duct and the discharge duct must be closed during air circulation and connected to a connection duct during sterilization. Therefore, it must be selectively opened and closed. To solve this problem, both ends of the supply duct and the discharge duct are closed with duct covers. The duct cover is fastened with a flange, and the flange is used as a fastening object when the connection duct is coupled. In addition, the duct cover can be pivotally opened and closed by being hinged on the flange. That is, the connection duct can be coupled in a rotating state without separate separation.

(Example 3-3) In Example 3-1, the movable duct sterilizer of the present invention,

The connection duct 130 is formed of a flexible tube; includes.

The supply duct and the discharge duct are installed at regular intervals at different intervals according to the installation conditions. If the connecting duct is not flexible, the supply duct and the discharge duct cannot be communicated. To solve this, the connection duct is preferably formed of a flexible tube. The flexible pipe may be formed of a main room pipe or a bellows.

(Example 3-4) In Example 3-1, the movable duct sterilizer of the present invention,

And a connection duct flange formed at both ends of the connection duct 130 and formed at both ends of the supply duct 110 and the discharge duct 120.

Connection duct flanges are formed at both ends of the Yeongyeol duct to ensure ease of coupling. It is preferable that the connection duct flange matches the supply duct and the discharge duct flange. The flanges are coupled by fastening means. It may be coupled with a bolt or a pin, and may be coupled using a clamp 150.

The clamp is for temporarily joining the two flanges. That is, during the sterilization process, both ends of the supply duct and the discharge duct are opened, and the connection duct can be quickly and easily fastened by a clamp while in contact with the connection duct.

In another embodiment, instead of a flange, a socket (not shown) partially inserted inside or outside both ends of the duct and the connecting duct is formed, and a band clamp (not shown) is used that is coupled outside the fastening position of the socket and the duct. Thus, two ducts can be combined.

(Example 3-5) The movable duct sterilizer of the present invention in Example 3-4,

A gasket (not shown) coupled between the flanges is fastened.

The usual gasket is to improve the airtightness of the two contact portions. Accordingly, the gasket is positioned between both end flanges to prevent the sterilization gas from leaking during the sterilization process. A gasket insertion groove <not shown> may be formed in the connection duct flange for stable seating of the gasket.

(Example 4-1) In Example 3-1, the movable duct sterilizer of the present invention,

In a normal air circulation process, the supply duct and the discharge duct are combined with the air circulator. However, the sterilization process shuts off the air circulator and the duct (supply duct and discharge duct) and must communicate with the sterilization device. To implement this, connecting pipes are formed in the supply duct and the discharge duct, respectively. The connection pipe has a three-way branch, and combines the air circulator and duct (supply duct and discharge duct) during the air circulation process, but communicates with the sterilization device instead of the air circulator during the sterilization process.

The inside of the connecting pipe should be able to automatically and manually control the opening and closing direction. An opening and closing plate is formed inside the connector. The opening and closing plate may selectively open and close an air circulator or a sterilizer. The opening/closing plate forms a pivoting hinge, and is pivoted around the pivoting hinge in the connection pipe. In addition, the rotational hinge transmits rotational power through a shaft that extends outside the connection pipe. The rotational power may be operated using an electric motor, or may be manually operated by mounting a handle. The electric motor is automatically controlled by a control device.
