【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1 to FIG. 3, reference numeral 1 is a deodorizing and sterilizing apparatus installed at a proper place in a room to be fumigated, and an air inlet / outlet port 3 is provided at both ends of a housing 2. , 4 are provided, and a filter 5 is provided inside the air inlet 3.

An air introduction space 6 and an air mixing space 7 are provided in the housing 2 facing the air inlets / outlets 3 and 4, and a partition plate 8 is horizontally provided at an intermediate position between the spaces 6 and 7. It is provided and divides the space into an upper air passage 9 and a lower air passage 10.

Of these, the upper air passage 9 is configured to be slightly narrower than the lower air passage 10, and a creeping discharge type or a corona discharge type is provided at the boundary of the air passage 9 with the air introduction space 6. A fumigation ozone generator 11 is installed, and a corona discharge type deodorization ozone generator 12 is installed at the boundary between the lower ventilation passage 10 and the air introduction space 6. A multi-porous ozone decomposing catalyst 13 containing manganese dioxide as a main component, for example, which is an ozone decomposing device, is disposed downstream.

In the figure, 14 is a fan provided on the downstream side in the housing 1.

[0011]

[Action]

 In the deodorizing and sterilizing apparatus of the present invention configured as described above, the conventional switching door that switches the ventilation passages 9 and 10 for each fumigation and deodorizing operation is eliminated, so that the structure is simplified and the installation space of the door is saved. Therefore, the size of the device can be reduced, and the ozone leakage due to the switching door and the durability problem due to ozone of the door driving motor do not occur.

In the present invention, the ozone generators 11 and 12 are provided respectively for fumigation and deodorization, but since the ozone generator 11 for fumigation only needs to generate ozone, this can be achieved by, for example, low-cost ceramics. High cost can be suppressed by using the ozone-type ozone generator.

Next, when the deodorization sterilization apparatus 1 is operated for deodorization, the apparatus 1 is installed at a proper place in a closed room, the fumigant ozone generator 11 is turned off, and the deodorant ozone generator 12 is placed. And the fan 14 are driven.

By doing so, as shown in FIG. 1, the air in the room is taken into the housing 2 from the air inlet 3, moves through the filter 5 to the air introducing space 6, and is guided to the ventilation paths 9 and 10. Get burned. Of these, the air guided to the air passage 9 passes through the fumigant ozone generator 11 in the OFF state, moves to the downstream side without any treatment or action in the device 11, and the air mixing space 7 Be led to.

On the other hand, the air guided to the air passage 10 passes through the deodorizing ozone generator 12 which is in the ON state, and in contact with the ozone generated in the device 12 at that time, moves in the air passage 10 to generate ozone. It is guided to the decomposition catalyst 13. In this case, since the contact time between ozone and the treated substance in the air passage 10 is short, the deodorizing and sterilizing action in the air passage 10 is very small.

When the air and ozone move in the ozone decomposing catalyst 13, ozone is temporarily collected in the porous portion and the ozone concentration in the pores is relatively concentrated, so that the air is removed. It oxidizes the organic components contained in it, and exerts deodorizing and bactericidal actions to decompose the odor contained in the organic components and sterilize various bacteria.

On the other hand, ozone is decomposed by reacting with manganese dioxide, which is the main component of the catalyst 13, in parallel with the above deodorizing action and sterilizing action, and its deodorizing and sterilizing ability is removed, that is, After being harmlessly prepared, it is moved to the air mixing space 7, merges with the air passing through the ventilation passage 9 in the space 7, and is discharged to the outside from the air outlet 4.

The air thus taken into the deodorizing and sterilizing apparatus 1 can smoothly move through the ventilation paths 9 and 10 which are the entire cross-sectional area of the deodorizing and sterilizing apparatus 1, so that the ventilation path on the fumigation side is different from the conventional one. Compared with the one that is blocked by the switching door and the air tends to stagnant at the relevant part, the passing air flow rate is increased, and the deodorization sterilization efficiency per unit time is improved accordingly.

Next, when the deodorization sterilization apparatus 1 is fumigated, the apparatus 1 is installed in a suitable place in a closed room, the deodorization ozone generator 12 is turned off, and the fumigation ozone generator 11 is used. The fan 14 is driven.

In this way, as shown in FIG. 2, the air in the room is taken into the housing 2 from the air inlet 3, moves through the filter 5 to the air introduction space 6, and is guided to the ventilation paths 9 and 10. Get burned. Of these, the air guided to the air passage 10 passes through the deodorizing ozone generator 12 and the ozone decomposing catalyst 13 in the OFF state, and moves to the downstream side without being subjected to any processing or action during these periods. And is guided to the air mixing space 7.

On the other hand, the air guided to the air passage 9 passes through the fumigant ozone generator 11 in the ON state, and at that time, the air generated in the device 11 comes into contact with the ozone and moves in the air passage 9 to generate air. After merging with the air that has passed through the air passage 10 in the air mixing space 7, the air containing ozone flows out from the air outlet 4 and diffuses into the room.

In this way, after the ozone is diffused into the room, the fumigant ozone generator 11 is driven for a predetermined time, and when the room is filled with ozone, the driving of the ozone generator 11 and the fan 14 is stopped.

On the other hand, when the ozone concentration in the room gradually rises before and after such a stopping operation, the ozone oxidizes the organic components in the air in the room to start the deodorizing action and the sterilizing action, and the organic components Decomposes the odor contained in and sterilizes mold and other bacteria. The movement of indoor air is suppressed along with the stop of the driving, and ozone and the organic components in the air are in stable contact with each other, whereby the oxidizing action of the organic components in the air by ozone is enhanced, and deodorization and sterilization are performed. The action is accelerated.

After a lapse of a certain deodorization sterilization time by ozone, the fan 14 is driven while continuously maintaining the stopped state of the fumigant ozone generator 11 and the deodorant ozone generator 12.

In this way, as shown in FIG. 3, room air containing ozone is taken into the housing 2 from the air inlet 3, moves through the filter 5 to the air introducing space 6, and the ventilation paths 9, 10 are formed. Be led to.

Of these, the air guided to the ventilation passage 9 passes through the fumigant ozone generator 11 in the OFF state, is not subjected to any processing or action in the device 11, and is kept in the ozone-containing downstream side. To the air mixing space 7.

On the other hand, the air introduced into the air passage 10 passes through the deodorizing ozone generator 12 in the OFF state, is introduced into the ozone decomposition catalyst 13, and the remaining organic components in the air are oxidized in the porous portion thereof. The odor in the remaining organic components is decomposed and the remaining bacteria are sterilized.

In parallel with the deodorizing action and sterilizing action of the ozone decomposing catalyst 13, the air is decomposed by reacting with manganese dioxide, which is the main component of the catalyst 13, and prepared harmlessly. It moves to the mixing space 7, merges with the ozone-containing air that has passed through the ventilation passage 9 in the space 7, and is discharged from the air outlet 4 to the outside.

In this manner, the above operation is performed for a predetermined time, and ozone in the room air is gradually decomposed to be harmlessly prepared, and then the drive of the fan 14 is stopped. Therefore, after this, people and animals and plants can enter the room.

Even during such a fumigation operation of the deodorizing and sterilizing apparatus 1, the inflowing air can smoothly move through the ventilation passages 9 and 10 which are the entire cross-sectional area of the apparatus 1, so that the deodorizing side as in the conventional case can be removed. The flow rate of passing air is increased and the ozone resolution rate per unit time is improved as compared to the case where the ventilation passage is blocked by the switching door and the air tends to stagnant in that part.

As described above, in the present invention, the two ozone generators 11 and 12 are provided so that the fumigation operation and the deodorizing operation can be independently performed, so that the operations can be finely performed.

[0032]

[Effect of the device]

 As described above, the deodorizing and sterilizing device of the present invention is provided with the fumigant ozone generating device and the deodorizing ozone generating device in the housing. Since the ozone decomposing device is installed in the air passage of the equipment, deodorant operation and fumigation operation can be independently performed, and the air flow rate moving through each air passage is increased to improve their operating efficiency. can do.

Further, in the present invention, since the conventional use of the switching door for opening and closing the ventilation passage is eliminated, it is possible to reduce the size of this kind of device by the space of the switching door, and to seal the switching door and drive the door. This has the effect of simultaneously solving the problem of durability deterioration due to ozone in the motor.
