2. Description of the Related Art Generally, in a store such as a supermarket, a sales floor in which a refrigerated showcase, a gondola, etc. are arranged and a backyard in which a working room, a refrigerating room and a freezing room are provided are partitioned by a wall surface.

[0003] In the backyard, a process of processing seafood, meat, etc. for display in a refrigerated showcase or the like arranged in a sales floor is carried out. The odor and germs that cause work conditions in the backyard are deteriorated and work efficiency is reduced.

Therefore, conventionally, an ozone deodorizer is used to oxidize and decompose odorous components and bacteria by ozone to create a favorable environment. FIG. 7 shows an example of a conventional ozone deodorizing device 21, which is a box-shaped device body 22.
The ozone generating pipes 25 are arranged in the inner part of the base plate, the outside air suction port 26 is formed on the bottom plate, and the outside air outlet 27 and the blower fan 28 connected to it are arranged on the front door 23. Ozone O3 from the ozone generating pipe 25 is mixed into the outside air taken in from the device, and the ozone-mixed air is blown out of the device from the outlet 27 by the blower fan 28 to oxidize and decompose odorous components and bacteria in the room with ozone. However, the indoor environment is kept good.

[0005]

However, in this ozone deodorizing device 21, since the distribution route of the outside air taken in is not determined, a flow does not form around the ozone pipe where the ozone concentration is high, and the sucked outside air is sufficient. In addition, there is a problem that ozone having a high concentration cannot be supplied to the outside of the device without being mixed with ozone. In addition, this device 2
In No. 1, since the ultraviolet ray from the ozone generating tube 25 directly hits the storage parts such as the blower fan 28, there is a problem that the blower fan 28 and the like are easily deteriorated.

Therefore, in order to prevent the deterioration of the storage parts such as the blower fan due to the ultraviolet rays, as shown in FIG. 8, a direct radiation prevention plate 39 is provided between the ozone generating tube 35 and the storage parts such as the blower fan 38. Although the ozone deodorizing device 31 is also used, in the ozone deodorizing device 31, most of the outside air taken in is discharged to the outside of the device from the blowout port 37 by the blower fan 38 without passing through the ozone pipe 35. Therefore, there is a problem that ozone O3 having a high concentration around the ozone generating tube cannot be sufficiently mixed and ozone having a high concentration cannot be supplied to the outside of the apparatus.

In view of the above-mentioned conventional circumstances, the present invention supplies the high concentration ozone to the outside of the device by discharging the outside air sucked into the ozone deodorizing device to the outside of the device in a state of being sufficiently mixed with the ozone. An object of the present invention is to provide an ozone deodorizing device which prevents deterioration of a storage component such as a blower fan arranged in the ozone deodorizing device due to ultraviolet rays from an ozone generating tube.

[0008]

In order to achieve the above object, the present invention has an ozone generating tube arranged in a box-shaped apparatus main body having a front door attached, and the ozone generated by this ozone generating tube is used as an apparatus.

After being mixed with the mixture, it is directed upwards to form an external air circulation path that forcibly discharges this highly concentrated ozone-containing external air from the upper opening of the shielding member to the outside of the device through the air outlet of the front door. It is characterized in that.

Further, in the ozone deodorizing apparatus of the present invention, the suction port for the outside air is provided on the top plate of the main body of the apparatus, the periphery of the blower fan is covered with the shielding member of the lower opening, and it is taken in from the suction port of the top plate of the main body of the apparatus. The outside air is mixed with high-concentration ozone through the periphery of the ozone generation pipe, then is directed downward, and the high-concentration ozone-mixed outside air is forcedly discharged from the lower opening of the shielding member to the outside of the device through the outlet of the front door. It is characterized by forming a route.

Further, in the ozone deodorizing apparatus of the present invention, the outside air suction port is provided on one side plate of the apparatus main body, and the periphery of the blower fan is covered with a shielding member having an opening on the other side plate side. The outside air taken in from the suction port is mixed with high-concentration ozone through the periphery of the ozone generation pipe and then directed to the other side plate side, and this high-concentration ozone mixed outside air is provided on the other side plate side of the shielding member. It is characterized in that an outside air circulation path is formed to force the air to be discharged out of the device through the air outlet of the front door.

The blower fan and the ozone generator tube are
It is good to be able to turn on / off by automatic operation with a time switch. This can eliminate the need for daily operations.

Further, in the present invention, particularly in a work place prefabricated refrigerator or the like, ozone is generated only at night and the concentration is controlled so as not to affect the human body even during generation, in order to avoid contact with ozone for a long time during work. Ozone rapidly decomposes when it comes into contact with the atmosphere, and atomic oxygen with a strong oxidizing power generated at that time oxidizes and decomposes odors, and sterilizes it. Since it causes harmful effects such as violating, it is set to 0.1 ppm or less in the working environment standard of the Industrial Safety Law. Therefore, in the present invention, 0.04 to 0.1 pp that does not affect the human body
The ozone concentration in the room is suppressed to about m, and a good environment is created for the human body by the purifying and sterilizing action.

Further, in the present invention, in consideration of a case where the operator is forced to enter the room during the ozone generation at night due to an emergency or security reasons, the ozone is interlocked with the lighting of the room lighting such as the workplace. It is advisable to provide a safety measure function that forcibly stops the occurrence. Specifically, it is advisable to provide a relay circuit that energizes the relay coil by energizing the room lighting to open the relay contact in the wiring between the room lighting, the blower fan, and the ozone generating tube.

[0014]

The outside air taken in through the suction port of the main body of the apparatus by the suction force of the blower fan mixes with high-concentration ozone when passing around the ozone generating tube. Then, the high-concentration ozone-mixed outside air is forcibly discharged from the opening of the shielding member to the outside of the apparatus through the outlet of the front door. Ozone odor in the air is efficiently oxidatively decomposed and sterilized by the high-concentration ozone discharged together with the outside air, and a good environment for the human body can be efficiently created.

In addition, as described above, in the present invention, the ultraviolet rays emitted from the ozone tube are prevented from directly hitting the storage parts such as the blower fan by the shielding member while performing the efficient purifying and sterilizing action. It is possible to prevent such deterioration.
