Ozone killers 3 and 4 for decomposing ozone are provided at the intake and exhaust ports of the duct 2, and a blower 5 for ozone decomposition is provided in the duct 2. A compressor 7 is provided at the upper part of the casing to compress the air taken in and supply it to the ozonizer 6.
[0004]
A sealed ozonizer 6 that generates ozone by electric discharge in a sealed container is disposed in the lower part 1 b of the casing 1. A pipe 8 for taking in compressed air from the compressor 7 is connected to the ozonizer 6, and a discharge pipe 9 for discharging the generated ozone gas to the outside of the apparatus is connected to the ozonizer 6. Reference numeral 10 denotes a cooling blower for cooling the ozonizer 6, and an air intake port 11 and an air discharge port 12 for taking in the air AIR for cooling the ozonizer 6 are provided at the lower part of the casing.

When such an ozone deodorizing and sterilizing apparatus is arranged and operated in a hotel room, a hospital room or a locker room, etc., air is supplied from the compressor 7 to the ozonizer 6 and is ozonized by the ozonizer 6. The room is fumigated and deodorized and sterilized with ozone O ₃ discharged from the discharge pipe 9. After the fumigation is completed, the compressor 7 and the ozonizer 6 are deactivated, and the ozone decomposing fan 5 is operated for a certain period of time, so that residual ozone in the room is decomposed by the ozone killer 3 when it is sucked into the duct together with the air AIR. It becomes oxygen O ₂ and is released into the room together with the air AIR. The ozone killer 4 is used to protect the blower 5 from corrosion caused by ozone.
[0006]

[0013]
【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In addition, the same code | symbol was used for the member similar to the prior art example mentioned above.
[0014]
FIG. 1 is a side sectional view of an embodiment of the ozone deodorizing and sterilizing apparatus of the present invention. FIG. 2 is a front view of an open-type ozone generator used in the ozone deodorizing and sterilizing apparatus shown in FIG. 1 and proposed by the present inventors (filed on May 22, 1995).
[0015]
In FIG. 1, a casing 1 is divided into upper and lower parts, and a duct 2 penetrating the casing 1 is provided in an upper part 1 a in the casing 1.

[0016]
An air intake port 11 and an ozone discharge port 12 are formed in the lower part 1 b of the casing 1. An open ozone generator 13 is disposed in the lower part 1 b of the casing 1. A blower 14 that blows a large amount of air to the ozone generator 13 is provided between the ozone generator 13 and the air intake 11 in order to generate a large amount of ozone.
[0017]
Here, the ozone generator will be described.
[0018]
In FIG. 2, ozone having a dielectric plate 22 interposed between a high voltage electrode 20 having a cross section formed in a comb shape and applied with an alternating high voltage and a ground electrode 21 having a cross section formed in a comb shape and grounded. A generation electrode cell 23 is formed.
[0019]
In the case 24 having a square cross section, for example, two sets of ozone generating electrode cells 23 are accommodated in such a manner that the high voltage electrodes 20 face each other, and are pressed by pressure welding bolts 25. A wire mesh 26 is provided on the front and rear surfaces of the case 24 for safety. An output terminal of an AC high voltage power supply 27 is connected to the high voltage electrode 20. The ozone generator 13 is arranged so that air from the blower 14 is supplied in a direction perpendicular to the paper surface. That is, the flow paths Ua and Va formed in the electrodes 20 and 21 are disposed so as to face the air intake port 11 and the ozone discharge port 12.
[0020]
Next, the operation of the embodiment will be described.
[0021]
When the ozone deodorizing sterilizer is activated, the ozone generator 13 and the blower 14 are activated. An AC high voltage is applied from the AC high voltage power supply 27 to the high voltage electrode 20, and creeping discharge occurs between the ground electrode 21 and the high voltage electrode 20 on the surface of the dielectric plate 22.

To be released. The room is sufficiently fumigated and deodorized and sterilized in a short time by this large flow rate of ozone gas O ₃ .
[0022]
When ozone fumigation is performed for a predetermined time, the AC high voltage power supply 27 and the blower 14 are stopped, and the generation of ozone O ₃ is stopped. At the same time, the blower 5 operates for a certain period of time, and residual ozone in the room is taken together with the air AIR from the intake port and decomposed by the ozone killer 3 to release oxygen O ₂ and air AIR into the room from the exhaust port. When all the residual ozone in the room is decomposed, the ozone deodorizing and sterilizing process is finished.
