Description

Clean room with air shower, dust collection and sterilization function, and multi-user independent access type clean booth applying it

The present invention is provided at the entrance of a building to remove bacteria and dust attached to the user's body or clothes to suppress disease infection caused by bacteria and to eliminate indoor contamination caused by dust, and a clean with dust collection and sterilization functions It relates to a room and a multi-party independent entry-exit clean booth to which it is applied.

Recently, in order to prevent the spread of Coronavirus Infectious Disease-19 (COVID-19), clean booths with the function of sterilizing the body and clothes of users are being installed at the entrances of buildings such as medical institutions, airports, schools, libraries, and government offices. .

Such a clean booth includes a main body having an inlet and an outlet on the front and rear respectively, and a treatment space for communicating the inlet and the outlet therein, a blower provided inside the main body to generate wind and pressurize it toward the treatment space; It is provided inside the main body and is composed of a sterilization means that radiates infrared or ultraviolet rays toward the processing space.

In other words, when a user enters the treatment space of the main body through the entrance, the clean booth supplies wind to the user for a set period of time and emits infrared or ultraviolet light toward the user to separate and sterilize the bacteria on the user's body and clothes. is the structure

However, in the conventional clean booth, when the bacteria separated from the user's body and clothes are not properly sterilized by infrared or ultraviolet rays, there is no separate means for sterilizing and sucking them again, so that they remain on the inner floor of the main body. At this time, there is a problem in that the bacteria remaining on the inner floor of the main body are transferred to the body or clothes of other users who continue to enter the processing space of the main body from the next turn, and thus the prevention function cannot be performed properly.

In addition, the conventional clean booth is configured in a small size so that only one user can enter the processing space of the main body at a time in order to prevent transmission between users, so that multiple users cannot use it at the same time. Here, if there are many users who want to enter the building, it takes a lot of time to enter the building, and as the waiting time becomes longer, contact between users waiting to enter the building is caused, and there is a problem in that the prevention of transmission between users is poor.

Therefore, in order to properly perform the quarantine function, it is possible to sterilize and dust not only the bacteria and dust attached to the user's body and clothes, but also the bacteria and dust that have fallen on the floor after being separated from the user's body and clothes. It is urgent to research and develop a clean booth with a structure that allows users to simultaneously use it in an independent processing space, eliminating waiting time and avoiding contact between users.
