Description

TECHNICAL FIELD The present invention relates to a deodorizing device for removing odors and bacteria in a room or the like.

[Conventional technology]

Conventional deodorizers are water-soluble odor components that can be removed by water by first washing the air with the highest possible odor concentration in order to remove the odor components that are said to have 400,000 types. Are removed, and thereafter, cleaning is performed with a chemical solution such as acid or alkali to remove odorous components that can be removed with the acid or alkali. The odorous components that cannot be removed by these operations were removed by an adsorbent such as activated carbon as a finishing treatment.

[Problems to be solved by the invention]

However, according to the conventional example as described above, the odorous components are removed or oxidatively decomposed through various steps, so that the structure becomes complicated and the apparatus tends to be large-scale. Moreover, since it is intended to treat the air containing the odorous component of the highest possible concentration, the gas-liquid contact efficiency is high, but the oxidative decomposition of the odorous component itself takes a relatively long time, and the odorous component is sufficient. However, there is a possibility that it will be the next step without being oxidized and decomposed. Therefore, as a result, the odorous components in the air are not sufficiently removed, and the efficiency of removing the odorous components becomes low. Therefore, if the oxidative decomposition time is set to be long in order to improve the efficiency of removing the odorous components, the size of the apparatus itself will be increased. Further, the conventional example does not have a function of removing Escherichia coli, green concentrated bacteria and various bacteria in the air, and it is not possible to remove them at the same time, and a separate device is required to remove them. .

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a deodorizing device having a simple device structure, a small size, and an antibacterial function.

[Means for solving problems]

In order to solve the above problems, there is provided a deodorizing device having a rotating disk soaking part, which is formed by immersing and rotating a part of a disk body having a gas-liquid contact part through which air can pass, The odor inside is oxidatively decomposed by the mixed liquid held in the gas-liquid contact part, and the bacteria in the air are further removed and sterilized by the antibacterial auxiliary filter and the mixed liquid held in the gas-liquid contact part. And a special airtight chamber into which an adsorbent having a humidity control function is introduced, and the adsorbent adsorbs moisture in the air to about 65 It is to provide a deodorizing device in which the water containing the adsorbent is released into the air when the humidity is less than about%.

[Action]

According to the above configuration, the air containing the odorous component is uniformly diffused in the air by the odor diffusion filter, and general bacteria are removed by the antibacterial auxiliary filter.
Further, the air in which the odorous components are uniformly diffused passes through the gas-liquid contacting part which holds the mixed liquid in the rotary disk soaking part, whereby the odor in the air, Escherichia coli, green concentrated bacteria and the like are removed.

The storage tank 32 containing the mixed liquid C is set in the apparatus main body 2, and it is confirmed that the mixed liquid C reaches a predetermined liquid level in the tank 5 via the supply tank 33 and the communication pipe 16. Then, the disk drive switch 42 is turned on to rotate the rotating body 4, and the fan switch 40 and the rotation speed changeover switch 41 are turned on to rotate the fan 8 at a predetermined rotation speed to contain the odor component. Aspirate the air. The air containing the odorous components in the room is blown by the fan 8
Is sucked from the opening 2a of the apparatus body 2 by the
First, coarse dust, dust and the like are removed by the net 11 of the filter unit 3 and enter the odor diffusion filter 12, where the odorous components are sucked and diffused into the air to become uniform.

Next, the air is filtered by the antibacterial auxiliary filter 13 to remove general bacteria other than Escherichia coli, green concentrated bacteria and the like, enters the fiber filter 14 to remove fine dust and mites, and passes through the protective net 15. Then, the air that has passed through the filter portion 3 enters the felt 19 through the large-diameter circular hole 17a and the small-diameter circular hole 17b of the lid 17 of the disk body 4 that constitutes the rotary disk immersion portion 6, and is retained in the fest 19. Contact with the mixed liquid C. Since the mixed liquid C contains the deodorant A and the antibacterial agent B, the odorous components in the air diffused by the odor diffusion filter 12 are rapidly oxidized and decomposed by the deodorant A, and the odor is lost. Moreover, the mixed solution C containing the antibacterial agent B is consumed,
If the liquid evaporates or decreases, the above-mentioned feeding device
The mixed liquid C is supplied from the storage tank 32 by 34. Therefore, until the mixed liquid C stored in the storage tank 32 is exhausted, the air is deodorized and sterilized while always maintaining a fresh initial deodorizing power and antibacterial power.

The air deodorized and sterilized in this way is discharged from the discharge port 38 to the room through the duct 37 by the fan 8. Therefore, the structure of the device is simplified and, as a result, the size can be reduced, and at the same time, the antibacterial function is provided. Furthermore, since the inside of the main body 2 of the apparatus can be kept at a predetermined humidity by the special airtight chamber 9, fungi such as mold do not adhere to the felt 19 of the filter portion 3 and the disc body 4, and a new odor component due to these fungi is obtained. And the deodorizing ability and the antibacterial ability are not lowered.

In this embodiment, the case where the number of the storage tank 32 is one, that is, the case where the deodorant is one type has been described, but the present invention is not limited to this, and the number of the storage tanks 31 is two, three, or the like. It may be a large number.

As described in detail above, the deodorizing device of the present invention is a deodorizing device having a rotating disk dipping portion which is formed by immersing and rotating a part of a disk body having a gas-liquid contact portion through which air can pass. The odor in the air is oxidatively decomposed by the mixed liquid held in the gas-liquid contact part, and the bacterial cells in the air are removed by the mixed liquid held in the antibacterial auxiliary filter and the gas-liquid contact part. A special airtight chamber, which is sterilized and into which an adsorbent having a humidity control function is put, is provided in the deodorant device, and the adsorbent adsorbs moisture in the air in the chamber so that the humidity is less than about 65%. In this case, the water containing the adsorbent is released into the air, and the air containing the odorous components is diffused uniformly in the air by the odor diffusion filter, and the antibacterial auxiliary filter is used. Evenly dispersed in the air, They are removed by bacteria auxiliary filter. Further, the air in which the odorous component is uniformly diffused passes through the gas-liquid contacting part holding the mixed liquid in the rotary disk soaking part, whereby the odor in the air, Escherichia coli, green concentrated bacteria and the like are removed.

Therefore, the odorous components in the air diffused by the odor diffusion filter are always fresh by rotation, and are deodorized at the gas-liquid contact part supplied with the deodorant having a strong deodorant and antibacterial effect and the antibacterial agent. Since it is efficiently oxidatively decomposed and sterilized by contact with an agent and an antibacterial agent, not only can the structure of the device be simple and compact, but the deodorant function is of course effective to have an antibacterial function. .
