Abstract

PURPOSE:To easily and safely replace a filter for decomposing ozone by moving a movable holder for an ozonizer while interlocking the pulling-out actuation of a reaction vessel and providing a safety switch which regulates electrification for the ozonizer according to movement of this movable holder and permits electrification according to return of the movable holder. CONSTITUTION:When a reaction vessel 4 is pulled out from a casing 1, a movable holder 8 is rotated to the reaction vessel 4 counterclockwise. Thereby an elastic contact 92 is separated from the terminal 91 of a safety switch 9 and electrification for an ozonizer 3 is interrupted. Therefor, even when interruption of electrification for the ozonizer 3 is forgotten in the case of replacing the reaction vessel 4, it is prevented that large amounts of ozone may be discharged into the chamber. Further, when the reaction vessel is introduced into the casing 1, the movable holder 8 is rotated to the introduction actuation of the reaction vessel 4 clockwise. The elastic contact 92 is again brought into contact with the terminal 91 and thereby electrification for the ozonizer 3 can be permitted.

Description

[Detailed Description of the Invention] <Prior Art> Conventionally, deodorizing devices have been used that decompose odors in the air through an interaction between ozone generated by corona discharge and odor components. The technique is disclosed in, for example, Japanese Utility Model Application Publication No. 1-28821.

The basic configuration of the prior art disclosed in this publication is shown in FIG. 6 of the present application. In this prior art, from the air intake port formed in the casing 10 to the casing 101
The external air sucked into the reactor is guided through an air introduction path 104 provided with an ozone generator 103 to a reaction vessel LOO in which a stirring fan 106 is provided. The rotation of the stirring fan 106 promotes agitation of ozone and odor components, thereby efficiently causing an interaction between ozone and odor components, and deodorizing the air.

Usually, some unreacted ozone remains in the air after deodorization, and this unreacted ozone is decomposed by the ozone decomposition filter 07 integrated into the second part of the reaction vessel 100, and then passed through the exhaust port. 08 to the outside of the casing], O]. An intake fan 109 is provided between the ozone decomposition filter 107 and the ozone decomposition filter 107. The ozone generator 103 generates ozone by generating a corona discharge using a high voltage from a high voltage power supply unit and converting a part of oxygen in the air into ozone.

The feature of this prior art is that the stirring fan 106 promotes the reaction between ozone and odor components, thereby increasing the deodorizing efficiency. In addition, since the agitation between ozone and air is promoted, the ozone concentration in the air introduced to the ozone decomposition filter 107 is made uniform in each part of the ozone decomposition filter 107, thereby ensuring that unreacted ozone is decomposed. I can do it. This technology can be used in cases where the air path from the ozone generator to the ozone decomposition filter is short or short, where ozone and air containing odor components tend to be poorly agitated, or where the ozone concentration tends to be uneven. Particularly advantageous.

<Problem to be solved by the invention> In the deodorizing device having the above configuration, an ozone decomposition filter]
07 is tightly integrated with the reaction vessel ]00 in a state of close contact. This is an ozone decomposition filter]0
This is because if there is a gap between 7 and the reaction vessel] 00, ozone may be exhausted into the room through the gap and have an unfavorable effect on the human body.

By the way, is it necessary to replace the ozone decomposition filter 07 when it reaches the end of its useful life?As mentioned above, the reaction vessel 100 and the ozone decomposition filter 107 are integrated with good airtightness. When replacing, is it necessary to also replace the reaction container ]00? However, in conventional deodorizing machines, no special consideration has been taken to replace these parts, so the replacement work is time-consuming. For example, since the reaction vessel 100 is screwed to the casing 101 at multiple locations, the attachment is extremely troublesome. In addition, since the reaction container] 00 and the air introduction path] 04 are integrally formed, the ozone decomposition filter] 07 and the reaction container], O
Is it necessary to attach and detach the ozone generator 103 every time O is replaced?

Also, when replacing the reaction vessel 100, the ozone generator 1
Sometimes people forget to turn off the power to 03, and in this case, a large amount of harmful ozone is exhausted into the room, which poses a safety problem.

This invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a deodorizing device that allows the ozone decomposition filter to be replaced easily and safely.

A deodorizing device of the present invention for achieving the object described in item 1 above includes an ozone generator disposed at the bottom of a reaction vessel built in a casing, and an ozone generator disposed at the bottom of a reaction vessel built in a casing to generate air within the reaction vessel. In a deodorizing device that deodorizes the odor components contained in the air by reacting them with ozone, decomposes the ozone remaining in the deodorized air using an ozone decomposition filter integrated in the reaction vessel, and then exhausts the air. , the reaction container is loaded into the casing so that it can be pulled out in a direction intersecting the air flow path, and the ozone generator is moved in conjunction with the withdrawal operation of the reaction container and in conjunction with the loading operation of the reaction container. The ozone generator is supported by a movable holder that returns when the movable holder moves, and also controls the energization to the ozone generator as the movable holder moves and allows the energization when the movable holder returns. It is equipped with a switch.

Effects> According to the deodorizing device configured as described above, the reaction container can be pulled out from the casing in a direction intersecting the air flow path together with the ozone decomposition filter. Then, by moving the movable holder and operating the safety switch in conjunction with the pulling out operation of the ozone generator, it is possible to restrict the supply of electricity to the ozone generator and stop the generation of ozone. Further, the moved movable holder can be returned in conjunction with the operation of loading the reaction container into the casing, and thereby the safety switch can be operated again to permit energization of the ozone generator.
