Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a sterilizer which heats and gasifies a sterilizing agent and guides it into the room to be sterilized by using the power of a separately installed air conditioner or blower.

[Prior Art] Conventionally, when sterilizing the inside of a room, each room is individually sterilized by generating a sterilizing agent spray or sterilizing gas, which is troublesome when many rooms are targeted at the same time. was there.

In addition, conventional sterilizing gas such as formaldehyde gas has a problem of residual residue and requires exhaust treatment, which complicates the sterilizing process and is not suitable for automatic sterilizing.

[Problems to be Solved by the Invention] The present invention has been made in view of the above circumstances, and is a sterilizing apparatus that can effectively use a sterilizing agent and that enables automatic exchange of the sterilizing agent to facilitate maintenance. The purpose is to provide.

[Means and Actions for Solving the Problems] In order to achieve the above object, the present invention provides a main body of a sterilizer having a suction port at a lower part and a blow port at an upper part, and a gas passing through the sterilizing device body. A disinfectant filling tank composed of a material through which gas is passed and is provided in a plurality of folds from the upper part to the lower part in the apparatus main body, a disinfectant replenishing tank connected to the upper part of the disinfectant filling tank, and the disinfectant. A sterilizing agent recovery tank connected to a lower portion of the filling tank via a discharge valve, and a heater provided in the sterilizing agent filling tank. The sterilizing agent is heated by a heater installed in the filling tank to generate a large amount of sterilizing gas, and the sterilizing gas is sent to the room through an air conditioning duct to sterilize microorganisms adhering to the room.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which a duct-shaped sterilizer main body 1 is provided with a suction port 2 in the lower part and a blow port 3 in the upper part, and is configured to allow gas to pass inside. . Inside the main body 1 of the sterilizer, a sterilizing agent filling tank 4 is provided in a plurality of folds, for example, three folds (or two folds) from the upper part to the lower part. The sterilizing agent filling tank 4 is made of, for example, a mesh-like material through which gas easily passes. A bactericide supply tank 5 is provided above the bactericide filling tank 4.
Are connected. A sterilizing agent recovery tank 7 is connected to the lower portion of the sterilizing agent filling tank 4 through a discharge valve 6 which can pass or block the sterilizing agent. A heating heater 8 for generating a sterilizing gas such as an electric heater is provided in the upper ⅓ portion (or ½ portion) of the sterilizing agent filling tank 4.

As the bactericide 9 used in the example of FIG. 1, zeolite impregnated with stabilized chlorine dioxide was used. When performing indoor sterilization, the sterilizer 9 is heated by the heater 8 incorporated in the sterilizer, and the power of an air conditioner or blower separately installed by gasifying stabilized chlorine dioxide is used to sterilize through the duct. Guide it indoors and sterilize it.

In addition, since the zeolite after chlorine dioxide generation has an adsorbing ability, it is possible to adsorb a malodorous gas such as ammonia by utilizing the effect of the zeolite, and it is also possible to have a deodorizing effect.

That is, the sterilizing agent 9 is poured from the sterilizing agent supply tank 5 into the sterilizing agent filling tank 4 and used for indoor sterilization, and then stored until the next indoor sterilization. At the time of the next indoor sterilization in which the sterilizing gas-generated zeolite is brought into contact with the circulating air for deodorization, the discharge valve 6 is automatically opened, and the lowermost bactericide 9 is discharged to the bactericide recovery tank 7. At the same time, the sterilizing agent 9 is poured into the sterilizing agent filling tank 4 from the sterilizing agent supply tank 5 by the amount of the discharged sterilizing agent 9 under its own weight and exchanged.

At the next indoor sterilization, the sterilizing agent 9 in the sterilizing agent filling tank 4 is replaced with a new one, and the sterilizing agent 9 is heated by the heater 8 installed in the sterilizing agent filling tank 4 to produce a large amount of stabilized chlorine dioxide sterilizing gas. generate. The stabilized chlorine dioxide sterilizing gas generated in this way is sent to the room through the air conditioning duct,
Sterilizes microorganisms adhering to the room.

The amount of the sterilizing agent 9 poured into the sterilizing agent filling tank 4 is 1/3 (or 1/2) of the sterilizing agent filling tank 4 that is folded in three (or two), and this is sterilized for generating sterilizing gas. The agent is used as the main deodorant germicide 9 after gas is generated. Other 2 /
Although 3 (or 1/2) of the bactericide 9 remains before this filling operation, it still has a residual capacity in the deodorizing ability, so it is left in the apparatus for pretreatment.

The above embodiment has the following effects.

Since the zeolite impregnated with stabilized chlorine dioxide is used as a bactericide, it can be used both as an indoor automatic sterilizer and a deodorizer.

Since the disinfectant used once is reused for deodorizing treatment, the disinfectant can be effectively used.

Maintenance is easy because the germicide is automatically replaced.

Indoor sterilization can be performed by heating the germicide and generating a large amount of stabilized chlorine dioxide gas.

Since the sterilizer is vertical, it is difficult for powdered germicide to come out from the outlet.

The disinfectant can be exchanged without stopping the sterilization operation.

[Advantage of the Invention] As described above, according to the present invention, the sterilizing agent is automatically exchanged, which facilitates maintenance. Since the sterilizing device is vertical, it is difficult for powdered sterilizing agent to come out from the outlet, Can be exchanged without stopping the sterilization operation, and since the sterilizing agent used once is reused for pretreatment, the sterilizing agent can be effectively used.
