An ozone deodorizing device is generally known as a deodorizing device that deodorizes these malodorous components in the air.

Ozone is the second strongest oxidant in nature after fluorine. For this reason, in the ozone deodorizing device, if ozone remaining in the air after deodorization is released into the atmosphere, it may have a bad influence on the human body such as a respiratory disorder. Therefore, the ozone deodorizing device is generally equipped with an ozone decomposing filter. FIG. 6 is a perspective view showing the overall configuration of a general ozone deodorizing device.
In the figure, reference numeral 1 denotes an apparatus main body having an intake port 11 and an exhaust port 12, and an odor component contained in air introduced into the apparatus main body 1 from the intake port 11 by a blower 2 is generated from an ozone generator 3. After deodorizing by reacting with the ozone, the introduced air is exhausted from the exhaust port 12. In the figure,
5 is a reaction chamber, 6 is an ozone decomposition filter, 7 is a pre-filter, and 8 is an electrostatic filter.

However, in the conventional ozone deodorizing apparatus using the ozone catalyst shown in FIG. 6, the electrostatic filter is fixedly installed as an additional function, but the life is 3 times that of the catalyst. ~ 0.5 for 5 years
It is a very short one year. Due to this imbalance of life, the electrostatic filter must be replaced frequently for the catalyst,
The replacement work is complicated.

In view of the above, it is an object of the present invention to provide an ozone deodorizing device capable of extending the life of an electrostatic filter and replacing the electrostatic filter with a catalyst.

[0006]

According to a first aspect of the present invention, the odor component contained in the air introduced from the intake port by the blower is reacted with ozone generated from the ozone generator to deodorize. After that, in an ozone deodorizing device that exhausts the introduced air from the exhaust port, an ozone decomposing filter equipped with a catalyst that decomposes the ozone remaining in the deodorized air, and a static adsorption device that electrostatically adsorbs dust contained in the introduced air An electrostatic filter is provided, and the electrostatic filter is formed in a long strip shape and stretched between a pair of rotating rollers so as to be freely wound.

Further, the problem solving means according to claim 2 is the ozone deodorizing device according to claim 1, wherein a driving motor for rotationally driving the rotating roller to wind up the electrostatic filter and a deodorizing operation time are measured. A timer and a control circuit for controlling driving of the drive motor based on the output signal of the timer are provided, and the control circuit drives the drive motor for a predetermined period of time for each predetermined deodorizing operation time based on the output signal from the timer. It has a filter winding means.

[0008]

In the means for solving the problem according to the above-mentioned claim 1, since the electrostatic filter is formed in a long strip shape and is stretched around the pair of rotating rollers so as to be freely wound, the electrostatic filter is set in accordance with the deodorizing operation time. Can be rolled up. Therefore,
The life of the electrostatic filter can be extended to match the life of the catalyst of the ozone decomposition filter, and the electrostatic filter and the catalyst can be replaced at the same time and at one time.

According to another aspect of the present invention, when the timer measures a predetermined deodorizing operation time, the filter winding means drives the drive motor for a predetermined time based on the time to rotate the rotary roller and wind the electrostatic filter by a predetermined amount. .. Therefore, the electrostatic filter can be automatically wound up according to the deodorizing operation time.

As shown in FIG. 1, the inner box 1C has an opening 11C connected to the intake port 11 on the lower surface and an intake air introduced from the intake port 11 on the upper surface. Openings 12C for leading to 12 are formed respectively.

The apparatus main body 1 has a blower 2 for air circulation, an ozone generator 3, a reaction chamber 5, an ozone decomposition filter 6, a prefilter 7 and an electrostatic filter 8 built therein. Among them, the ozone generator 3, the reaction chamber 5, the ozone decomposition filter 6, and the electrostatic filter 8 are installed in the inner box 1C so as to be arranged in the middle of the air passage that is moved upward by the blower 2.

The blower 2 comprises a motor 2A and a fan 2B fitted to the shaft of the motor 2A. And
The motor 2A is attached to the lower surface of the top plate 11A of the outer box 1A, and the tip of the fan 2B is at the upper opening 12C of the inner box 1C.

Is formed by a partition box 51 that is connected to and communicates with. The ozone decomposing filter 6 is a honeycomb shaped body coated with an ozone decomposing catalyst in order to decompose the ozone remaining in the air after deodorization. The ozone decomposing filter 6 faces the ozone generator 3 and faces the ozone generator 3. It is located above the interior.

The electrostatic filter 8 is for further electrostatically adsorbing the dust not removed by the pre-filter 7, and is arranged below the reaction chamber 5. Then, as shown in FIG. 3, the electrostatic filter 8 is formed in a long band shape in order to correspond to the life of the ozone decomposition catalyst, and one end side of the electrostatic filter 8 is connected to the drive motor 20 for the first rotation for winding. The roller 21 is wound around the other end of the driven second rotating roller 22. In addition,

In the above structure, in order to deodorize the malodorous components in the air, first, the blower 2 is driven to introduce the external air into the apparatus main body 1 through the intake port 11 and react with the ozone generated from the ozone generator 3. By mixing in the container 5, the malodorous components in the air are decomposed and removed. At this time, when the timer 23 measures a predetermined deodorizing operation time, the control circuit 24 drives the drive motor 20 based on the output signal of the timer 23 to wind the electrostatic filter 8.

Here, the winding control of the control circuit 24 will be described with reference to FIG.
