Abstract

PURPOSE:To sterilize and deodorize a room and the air in the room, by preliminarily purifying the air in the room introduced into an ozone generator by an air filter. CONSTITUTION:A medium capacity air filter 4 is arranged to the front stage of an ozone generator 7 and a humidifier 8 and 90-97% of the dust, especially, org. dust in the recirculated air introduced into the generator 7 and the humidifier 8 can be removed. A change-over damper 5 freely slidable left and right is arranged to the front stage of an ozone decomposing apparatus 6 and can change over a recirculated air passage route selectively so that the recirculated air is directly raised to the air filter 4 through a bypass passage 6B at the operation time of the ozone generator 7 and raised through an ozone decomposing passage 6A at the stop time of the ozone generator 7. By this constitution, generated ozone can be entirely utilized in order to sterilize, disinfect and deodorize a room and the air in the room without being consumed in the oxidation of dust and ozone sterilizing effect can be enhanced still more.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention purifies indoor air with a filter, sterilizes, disinfects, and deodorizes indoor air with ozone, and cleans indoor air with ozone. The purpose is to provide a device that can prevent material deterioration of the material.

[Prior Art] It is well known that ozone O3 has sterilizing, disinfecting, and deodorizing effects.

Ozone generation/addition devices for sterilizing, disinfecting, and deodorizing indoor rooms and indoor air by utilizing the properties of ozone are well known and are increasingly being used in hospitals, food warehouses, and the like.

Furthermore, air purifiers that incorporate a dust removal filter after the ozone generator are also known for applications such as sterile factories and research laboratories that require not only sterilization and disinfection but also air purification. . (-For example, JP-A-60-255
(Refer to Publication No. 24) According to these conventionally known devices, sterilization and
Contaminated indoor air that needs to be removed is first guided to an ozone generator while still containing dust, where it is sterilized by ozone, and then filtered by a filter installed afterward, and then circulated indoors as sterilized clean air. It has become.

[Problems to be Solved by the Invention] In the conventionally known ozone sterilization/deodorization device described above, the contaminated indoor air is directly introduced into the ozone generator while still containing dust, so the generated ozone is First, it is consumed by the oxidation of dust and organic matter in the air, reducing the amount supplied indoors, which not only reduces the indoor sterilization effect, but also causes dust to adhere to the ozone generator and contaminate it, leading to a decrease in performance. There is a problem.

In addition, ozone 03 has a larger molecular structure and heavier specific gravity than oxygen 02, so the ozonized air tends to be insufficiently diffused, and the upper layers of indoor air, especially the air near the ceiling, do not circulate and stagnate, causing ozone There is also the problem that the sterilizing power of the ceiling is insufficient, resulting in insufficient sterilization and disinfection of the ceiling.

Furthermore, when operating for a long time, decomposition after ozone sterilization tends to be insufficient, and ozone tends to remain in the room.The strong oxidizing power of this residual ozone causes the materials in the room to deteriorate quickly, shortening the lifespan of the device itself. At the same time, in some cases, there are also health problems.

This invention attempts to solve the above problems.

[Problems and Means for Solving the Problems] The present invention provides means for solving the above-mentioned problems. Louver-shaped air outlet 9A at the top,
An ozone generator 7 and a humidifier 8 are arranged in parallel in the upper part of the housing A having 9B, and an air filter 4 is installed in front of the ozone generator 7 and a humidifier 8.
and ozone decomposition: with δ6 arranged in series,
By operating the switching damper 5, the circulating air is selectively transferred to the ozone decomposition section 6A or the bypass section 6B in the ozone decomposition device 6.
The gist of the invention is an ozone sterilization/deodorization device that is characterized by being able to pass through ozone.

[Function] Since the present invention has the above configuration, the indoor air introduced from the air intake port 1 at the bottom of the housing A is first removed by the screen-shaped pre-duster, and then passed through the bypass section 6B in the ozone decomposition device 6. After being introduced into the air filter 4 and cleaned, the ozonated air is introduced into an ozone generator 7 and a humidifier 8 which are arranged in parallel at the upper part of the housing A, and the ozonated air is passed through the louvered air outlet 9A to humidified air. is blown out from the air outlet 9B and circulated indoors.

Further, when the ozone generator 7 and the humidifier 8 are stopped, the circulating air can be passed through the ozone decomposition section 6A in the ozone decomposition device 6 by switching the switching damper 5.

Therefore, the indoor air introduced into the ozone generator 7 and the humidifier 8 is clean air that has been removed by the pre-duster installed in the air intake port 1 and further purified by the air filter 4. The generated ozone is not consumed by the oxidation of dust, and the entire amount is blown out from the upper air outlet 9A to the upper part of the room along the inclination angle of the louver, and is used for the purpose of sterilizing, disinfecting, deodorizing the room and indoor air, etc. Effectively used. Moreover, since humidified air is simultaneously blown out from the air outlet 9B, the sterilizing effect of ozone can be further enhanced. It is known that the bactericidal effect of ozone is enhanced by humidification. (Refer to Hokkaido Industrial Development Laboratory Report 1986, No. 40P, 69-751, "Sterilization of Bacillus Bacteria Spores by Gaseous Ozone") In this case, the louvered upper air outlets 9A and 9B are connected to the ozone generator 7 and the humidifier. 8 opens directly into the room without going through a filter or the like, so the flow rate of the blown air does not decrease, and the air is blown out from the gap provided by the louver toward the ceiling of the room according to the blowing angle at the required flow rate. Ru.

Furthermore, if the ozone generator 7 and humidifier 8 are operated for a long time and the indoor ozone concentration becomes rich, after the operation is stopped, the switching damper 5 is switched to transfer the circulating air to the ozone decomposer 6. By passing through the ozone decomposition section 6A, residual ozone in the room is rapidly decomposed in a short time.
In addition to preventing the deterioration of indoor substances, it also removes the toxicity of ozone and creates an environment where people can enter and exit in a short period of time.

Further, if the ozone generator 7 is stopped and operated, the air filter 4 functions as a normal air purifying device, so it can be used as an air purifying device that is harmless to humans and animals.

Therefore, the ozone sterilization/deodorization device can be operated at night or on holidays when no personnel are present, and can be used as a normal air purification device during working hours.

By operating the switching damper 5 to selectively allow circulating air to pass through the ozone decomposition section 6A or the bypass section 6B in the ozone decomposition device 6, the air introduced into the ozone generator 7 and the humidification device 8 can be Since the air can be purified by removing serum, the generated ozone is not consumed in the oxidation of dust, and the entire amount can be used for the purpose of sterilizing, disinfecting, and deodorizing indoors and indoor air. This can further enhance the bactericidal effect of ozone.

In addition, the upper air outlets 9A and 9B open directly into the room from the ozone generator 7 and the humidifier 8 without going through a filter or the like, so the airflow does not decline.
