Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to improvement of a sterilizing and deodorizing device for air that uses ozone.

(Prior Art) Conventionally, in this type of apparatus, for example, an electric suction fan, an ozone generator, and an ozone decomposer are sequentially arranged in a housing, and a dustproof net is attached to a position adjacent to the suction fan. There is also a gas introduction opening provided therein and a gas discharge opening provided near the ozone decomposer (see, for example, Japanese Utility Model Publication No. 60-24351).

(Problems to be solved by the invention) In this conventional device, the external air taken in by the electric suction fan is directly sent to the ozone generator, and after sterilizing and deodorizing the air at this location. Immediately, residual (excess) ozone was decomposed into oxygen by an ozone decomposer. Therefore, in the conventional apparatus, the time in which the air containing the bad odor and the microorganisms reacts with ozone is extremely short, so that the air is often returned to the room with insufficient sterilization and deodorization of the air.

Further, in the conventional device, as described above, the ozone generator is arranged on the discharge side of the suction fan. Therefore, when such a conventional device is used, ozone is sent to the ozone decomposer to be decomposed without being evenly distributed in the air discharged from the suction fan, and is then sent indoors. There were many things. As a result, in the conventional device, the characteristics and effects of ozone, which have excellent sterilizing power and deodorizing power,
It was something that could not be fully utilized and utilized.

The present proposal has been proposed in order to solve such a problem of the conventional device.

Therefore, the technical problem of the present invention is that the ozone is formed so that the time for sterilizing and deodorizing the air is extended, and that the ozone is diffused and distributed in the air taken into the main body of the device. An object of the present invention is to provide a sterilizing and deodorizing device for air that uses ozone, which is configured so that the deodorizing power can be fully utilized and utilized.

(Means for Solving the Problems) This proposal adopts the following technical means in order to solve such problems.

(Operation of the device) In the device of the present invention, first, the air taken in by the blower 1 is
Water and dust are removed by the first filter 6a provided inside the air intake 3 of the apparatus body 2. This air is blown by the blower 1 together with the ozone generated by the ozone generator 8.
It is discharged while being stirred. Since the discharge side 1d of the blower 1 is provided with the second filter 6b, the filter 6b not only further filters air, but also passes through the mesh of the filter elements of this filter 6b. Even while it takes a long time, ozone is used for sterilization and deodorization. After that, ozone is decomposed into oxygen by the ozone decomposer 7, and the decomposed air is sent to the room from the air discharge port 4 of the apparatus body 2.

When the storage chamber 9 of the ozone generator 8 is formed to communicate with the space S ₁ from the second filter 6b to the ozone decomposer 7, a part of the air passing through the second filter 6b is It is recirculated into the partition chamber 5 in which the blower 1 is arranged through the storage chamber 9 of FIG.

(Embodiment) A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

1 is a blower such as an electric fan. The blower 1 is configured to supply air from an air intake 3 of the device body 2 to the device body 2
This air is introduced into the room from the air discharge port 4 of the device body 2. Further, as shown in the figure, the blower 1 includes a partition chamber 5 formed in the lower portion of the apparatus main body 2.
It is arranged inside. 1a is a motor of the blower 1,
The motor 1a is arranged in the motor box 1b.
An external air inlet 1c is formed in the motor box 1b.

Reference numeral 6 denotes a filter unit provided in the apparatus main body 2 for filtering the air taken in by the blower 1 from the air intake port 3.
The filtering unit 6 includes a first filter 6a provided inside the air intake 3 and a second filter 6b arranged between the discharge side 1d of the blower 1 and the ozone decomposer 7. Is formed by. The filter elements of the first filter 6a and the second filter 6b are formed of, for example, glass wool, glass wool membrane, spongy metal, etc. In this case, the mesh size of the second filter 6b is larger than that of the first filter 6a. Selected in detail. The second filter 6b is formed to have a predetermined thickness.

Reference numeral 8 denotes, for example, a silent discharge type ozone generator provided in the apparatus main body 2. The ozone generator 8 is provided in a storage chamber 9 formed so as to communicate with the partition chamber 5. This storage chamber 9 is the front wall of the apparatus main body 2 in this embodiment.
It is formed on the back of 2a so as to extend in the vertical direction. In addition, an inlet 9a for air that has passed through the second filter 6b is formed in the upper part of the storage chamber 9, and is formed in communication with the space S ₁ from the second filter 6b to the ozone decomposer 7. .

In this embodiment, platinum is used for the electrodes of the ozone generator 8 and mica is used for the dielectric interposed between the electrodes. Further, in the ozone generator 8 of this embodiment, for example, the high voltage generator 10 arranged at an appropriate place in the main body 2 of the apparatus.
Therefore, it is configured to generate ozone by applying a high frequency voltage of 2000 V or less between the electrodes.

Reference numeral 7 is an ozone decomposer as described above. The ozone decomposer 7 is formed of, for example, a mesh container and an ozone decomposition reaction material housed in the container. The ozone decomposer 7 is arranged between the second filter 6b and the air discharge port 4 of the apparatus body 2 as shown in the figure. As the ozone decomposition reaction material, for example, a well-known material such as a pure iron wool fine wire or a catalyst for ozone decomposition may be used.

Next, the operation of this embodiment will be described.

First, when the impeller of the blower 1 rotates, air containing dust, moisture, malodor, microorganisms, etc. is sucked into the device body 2 from the air intake port 3 of the device body 2 through the first filter 6a. Therefore, at this time, dust and the like in the outside air are removed by the first filter 6a. At the same time, ozone generated by the ozone generator 8 is sucked into the partition chamber 5. In this case, the motor 1a of the blower 1 is covered by the motor box 1b, and when the impeller of the blower 1 rotates, the pressure inside the partition chamber 5 is lowered, and the external air flows into the box 1b from the inlet 1c. Then, it flows around the motor 1a and is sucked into the partition chamber 5 from the shaft through hole 1e (see FIG. 2). Therefore, in the case of the present invention, the ozone sucked into the partition chamber 5 does not enter the motor box 1b, so that the ozone does not oxidize the coil of the motor 1a.

Next, the ozone and the air sucked into the compartment 5 are blown by the blower 1
It is agitated by the impeller and is discharged from the discharge side 1d of the blower 1. Therefore, from the discharge side 1d of the blower 1 to the second filter
In the space S ₂ (reaction chamber) that reaches 6b, ozone is evenly distributed and diffused in the air, and sterilization and deodorization are effectively performed.

Then, after that, the air is further purified by the second filter 6b. The air is sterilized and deodorized by ozone while passing through the mesh of the filter element of the second filter 6b. Note that in the present proposal, bacteria and harmful substances captured by the second filter 6b are also efficiently sterilized and deodorized and decomposed by the excess ozone.

Further, in this embodiment, a part of the air that has passed through the second filter 6b flows into the storage chamber 9 through the inlet 9a formed in the upper portion of the storage chamber 9, and then is recirculated into the partition chamber 5. Therefore, in the case of this embodiment, since a part of the recirculated air has a longer sterilization and deodorization time with ozone, the effect of sterilization and deodorization of air is generally high. According to the present invention, even if a part of the air is recirculated in this way, the air flowing through the electrodes of the ozone generator 8 is cleaned, so that the electrodes are not adversely affected by moisture in the air. There is no problem such as a decrease in the ozone generation rate.

Most of the air that has passed through the second filter 6b is sent to the room from the air discharge port 4 through the ozone decomposer 7. The remaining (excess) ozone is the ozone decomposing unit 7 described above.
It is decomposed into oxygen and sent to the room.

In the above process, according to the present invention, the storage chamber 9 has the space S ₃ from the ozone decomposer 7 to the air discharge port 4 of the apparatus body 2 and the air inlet 9b as shown in FIG. 3, for example. It may be formed so as to communicate with each other.

Further, the present invention is not limited to the case where the air is recirculated in the apparatus main body 2. That is, in the present proposal, as shown in FIG. 4, all of the air taken in from the air intake 3 is
It may be formed so as to supply air from the air discharge port 4 into the room. In this example, in addition to the air intake 3 formed in the lower part of the device body 2, an auxiliary air intake 3a is formed in almost the center of the device body 2 so as to communicate with the upper part of the storage chamber 9. Has been done. Therefore, in this example, the first filter 6a is also arranged inside the intake port 3a.

(Effects of the Invention) Since the present invention has such a configuration, the following effects can be obtained by using it.

That is, in the device of the present invention, since the second filter is disposed between the discharge side of the blower and the ozone decomposer, the sterilization and deodorization of ozone is performed by the amount required to pass through the mesh of the filter element of this filter. Since the time can be lengthened and the partition chamber in which the blower is disposed and the storage chamber in which the ozone generator is stored are formed in communication with each other, ozone can be diffused and distributed in the air by the blower.

Therefore, if the device of the present invention is used, the sterilizing power and deodorizing power of ozone can be effectively utilized, and the sterilizing and deodorizing effects can be greatly obtained, which is a practically excellent effect.

When the storage chamber is formed to communicate with the space from the second filter to the ozone decomposer, part of the air passing through the second filter is returned to the partition chamber. Therefore, there is an advantage that the sterilizing and deodorizing treatment time by ozone becomes longer, and the sterilizing and deodorizing effect becomes large as a whole.
