[0031] As shown in Figure 5, the liquid supply unit 21a of the sterilization room 20 includes a pump 211 that applies pressure to the liquid when it is supplied, and a tank 212 for storing the liquid.

[0032] The liquid sprayed into the disinfection room 20 is a liquid with disinfecting and sterilizing effects, and the liquid used is one that is harmless to the user's body when sprayed. For example, it is desirable to use Eva Water (registered trademark).

[0033] As shown in Figure 3, the air ejection device 23 that forms the air curtain of the sterilization chamber 20 is configured to eject air from the top to the bottom of the housing 2 to prevent the sprayed liquid from flowing out of the housing 2 to the outside when the liquid is sprayed into the sterilization chamber 20. Furthermore, when the spraying of the liquid is finished, the control unit 5 controls the air ejection device 23 that forms the air curtain to stop operating in conjunction with the liquid supply unit 21a. In this embodiment, the air ejection device 23 is installed on the top of the housing 2, but it may also be installed on the bottom, left, or right side of the housing 2, as long as the sprayed liquid does not flow out to the outside of the housing 2.

[0034] As shown in Figure 6, the control unit 5 that controls the purification device 1 is configured to control a body temperature measurement unit 7a, a personal information input unit 7b, an audio output unit 7c, a first door 8 located on the entrance 6 side of the air shower room 9, a second door 12 located between the air shower room 9 and the disinfection room 20, an opening and closing means 8a for the first door 8, an opening and closing means 12a for the second door 12, a first sensor 11 for detecting whether a user has entered the air shower room 9, an air shower device 10, a first audio unit 13 in the air shower room 9, a second sensor 22 for detecting whether a user has entered the disinfection room 20, a spraying device 21, an air ejection device 23, and a second audio unit 24 in the disinfection room 20. The control method will be described later.

[0035] Next, the operation of this embodiment will be explained using Figures 1 and 7.

[0036] The purification device 1 of this embodiment is installed near the entrance of a facility such as a hospital. When a user moves in front of the entrance 6 of the purification device 1, an authentication device 7 installed near the entrance 6 of the purification device 1 verifies whether the authenticated user is authorized to enter the purification device 1, and determines whether to grant permission for the user to enter the purification device 1.

[0037] If authentication is confirmed by the authentication device 7 and entry into the purification device 1 is permitted, the control unit 5 of the purification device 1 checks whether there is a prior user in the air shower room 9 based on a signal from the first sensor 11 installed in the air shower room 9. In this confirmed state, the first door 8 remains closed.

[0038] If, upon confirmation, there is a user already inside the air shower room 9, the control unit 5 controls the audio output unit 7c located near the entrance 6 and outputs a message indicating that there is a user already inside and saying, "Please wait a moment." If there is no user already inside, the audio output unit 7c controlled by the control unit 5 outputs a message indicating permission to enter, and the control unit 5 controls the first door 8 of the air shower room 9 located on the entrance 6 side, moving the door opening / closing mechanism 8a of the first door 8 to the open position. The user then confirms that the first door 8 is open and enters the air shower room 9.

[0039] When a user enters the air shower room 9, a first sensor 11 installed in the air shower room 9 detects the user, and the control unit 5 uses the opening / closing means 8a of the first door 8 to move the first door 8 to the closed position.

[0040] When the first door 8 is closed, the air shower devices 10 located on the upper, left, and right sides of the housing 2, controlled by the control unit 5, activate and spray air for a predetermined time to remove any debris adhering to the user.

[0041] When the air shower device 10 has finished operating, the control unit 5 confirms that there is a previous user inside the disinfection room 20 based on a signal from the second sensor 22 installed in the disinfection room 20. In this confirmed state, the second door 12 remains closed.

[0042] If, upon confirmation, there is a user already inside the disinfection room 20, the first voice unit 13 located near the second door 12 is controlled by the control unit 5 and outputs a voice message indicating that there is a user and saying, "Please wait a moment." If there is no user, the first voice unit 13 controlled by the control unit 5 outputs a voice message indicating permission to enter, and the second door 12 is moved to the open position by the second door 12 opening / closing means 12a controlled by the control unit 5. The user then enters the disinfection room 20 after confirming that the second door 12 is open.

[0043] When a user enters the disinfection room 20, a second sensor 22 installed in the disinfection room 20 detects the user, and the control unit 5 uses the opening / closing mechanism 12a of the second door 12 to move the second door 12 to the closed position.

[0044] When the second door 12 closes, the control unit 5 controls the liquid supply unit 21a located in the machine room 20a, which then operates. The liquid is sprayed through the first pipe 21b, the branch pipe 21c, and the spray nozzle 21d from the top to the bottom of the spray chamber 20b of the disinfection room 20 that the user has entered, for a predetermined time to disinfect and sterilize any bacteria attached to the user. Simultaneously with the spraying of this liquid, an air ejection device 23, which forms an air curtain located near the exit 25, ejects air to block the exit 25, preventing the sprayed liquid from leaking outside the purification device 1. After a predetermined time has elapsed, the control unit 5 stops the supply of liquid from the liquid supply unit 21a and the ejection of air from the air ejection device 23 that forms the air curtain.

[0045] Afterward, the user exits through exit 25 and leaves the purification device 1.

[0046] According to the present invention, a single purification device 1 is equipped with an air shower room 9 and a sterilization room 20. After passing through the air shower room 9, the user is sprayed with a liquid that has a sterilizing and disinfecting effect in the sterilization room 20, thereby enabling the effective removal of attached substances and bacteria from the body.

[0047] According to the present invention, an air shower room 9 and a sterilization room 20 are provided within a single housing 2. Since this housing 2 is configured to be movable, it can be installed and removed from a wide range of facilities.

[0048] According to another invention, the air ejected in the air shower room 9 is purified by a filter 10c provided in the air shower device 10, and since the purified air circulates within the air shower room 9, it is possible to prevent user contaminants and viruses from being discharged outside the purification device 1.

[0049] According to another invention, the disinfection chamber 20 is composed of a machine room 20a and a spraying chamber 20b. A liquid supply unit 21a is provided in the machine room 20a, and liquid is supplied from the liquid supply unit 21a to the spraying chamber 20b via piping and sprayed. As a result, the liquid is not sprayed onto the liquid supply unit 21a, reducing the risk of failure of the liquid supply unit 21a. Furthermore, since the spraying area and the location where the liquid supply unit 21a is installed are separate, maintenance can be performed by entering only the machine room 20a. In addition, by reducing the internal volume to be sprayed, spraying efficiency is improved, making it possible to effectively disinfect and sterilize with a small amount of liquid.

[0050] According to another invention, the housing 2 is formed in a rectangular parallelepiped shape to match the protrusion that houses the door of the air shower chamber 9, the spray chamber 20b of the sterilization chamber 20 is formed with a width excluding the protrusion of the air shower chamber 9, and a machine room 20a can be provided in the area of ​​the remaining width after the protrusion, making it possible to efficiently arrange the air shower chamber 9 and the sterilization chamber 20 in the overall rectangular parallelepiped housing 2.

[0051] According to another invention, the control unit 5 provided in the purification device 1 checks for the presence of previous users before allowing entry into the air shower room 9 and sterilization room 20 within the purification device 1, and determines whether to permit subsequent users to enter, thereby ensuring that each individual's purification process is carried out reliably.

[0052] According to another invention, the entrance 6 of the housing 2 is equipped with a body temperature measurement unit 7a, a body temperature determination unit that determines whether the body temperature measured by the body temperature measurement unit 7a is within a specified range, and an audio output unit 7c that advises the user to visit a hospital if the body temperature determination unit determines that the body temperature is outside the specified range. This prevents infected persons from entering the facility and also helps to suppress infection within the facility and outside the facility by notifying infected persons by voice to visit a hospital.

[0053] According to another invention, the sterilization room 20 is provided with an air ejection device 23 located near the exit port 25, which forms an air curtain by ejecting air into the exit port 25, thereby preventing liquid from leaking out of the sterilization room 20.

[0054] It should be noted that the embodiments of the present invention are not limited to the configuration described above. In the embodiments of the present invention, body temperature and pre-registered personal information are entered into the personal information input unit 7b of the entry authentication device 7 for authentication. However, authentication of the user may also be performed by issuing an authentication code such as a QR code (registered trademark) during pre-registration and having the personal information input unit 7b read it. Furthermore, in the embodiments of the present invention, it was explained that an air ejection device 23 is provided near the exit 25 to form an air curtain in order to prevent the sprayed liquid from leaking out of the outside of the purification device 1. However, any configuration that prevents the sprayed liquid from leaking out is acceptable. For example, a door or a vinyl sheet may be provided near the exit 25. [Explanation of Symbols]
