Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an ozone deodorizing device that can effectively deodorize bad odors using ozone.

(b) Prior Art Conventionally, ozone has been used to deodorize, for example, the bad odor generated in a toilet bowl, ie, the bad odor generated during stool and urine.

Ozone eliminates odors by oxidizing and decomposing malodorous components through its oxidizing action, and a technology for deodorizing by incorporating such an ozone generator into a toilet was developed in JP-A-60
This method has already been disclosed in Publication No. -31719.

That is, this disclosed technology incorporates an ozone deodorizing device in the rear of the toilet bowl, sucks in bad odors from an inlet and draws them into the device, and contacts the ozone generated by an electric discharge in an ozone generator to remove the bad odors. It disassembles and deodorizes the waste and discharges it to an appropriate location, such as outside the toilet bowl.

(c) Problems to be Solved by the Invention However, such ozone deodorizing devices still have the following problems to be solved.

That is, in the deodorizing channel of the ozone deodorizing device, an ozone generator that generates ozone, an ozone mixing section that mixes ozone and bad odor, and a catalyst that decomposes residual ozone after deodorizing treatment are respectively arranged. was.

Such an ozone generator generates ozone by generating a high voltage from a discharge part, and the discharge part is attached to the deodorizing flow path, and a high voltage generator is connected to the same discharge part. The generator was attached to a case connected to the toilet bowl.

Furthermore, a control unit is connected to the high voltage generator, and the control unit controls the amount of ozone generated, etc., so as to sufficiently reduce the ozone concentration remaining in the exhaust gas after deodorization treatment. , safety to the human body was considered.

However, when ozone deodorization equipment generates ozone,
A high voltage generator generates high voltage, so if the high voltage generated by the high voltage generator were to leak, it could be transmitted to the human body through the case, which was extremely dangerous.

In addition, in order to generate ozone and deodorize bad odors,
When an ozone generator is activated, electromagnetic waves are generated from the high voltage generator, and these electromagnetic waves affect the control unit or various sensors built into the ozone deodorizing device, making it possible to perform controlled ozone deodorizing processing smoothly. There were no problems.

This relates to a deodorizing device.

Further, in the present invention, the ozonizer and the high voltage generator are
It is characterized by being molded from synthetic resin with conductive material embedded in it.

(e) Actions and Effects In the present invention, for example, when defecating using a toilet bowl, bad odor is inhaled through the inlet and reaches the ozone generator in the ozone treatment flow path, where it comes into contact with ozone generated from the ozone generator. However, the air is deodorized by the deodorizing action of ozone, and the deodorized air is discharged outward from the exhaust port at the other end.

Moreover, during this deodorization process, when ozone is generated from the ozonizer using high voltage from the high voltage generator, the high voltage generator of the ozone generator is molded with synthetic resin, so the ozone generator It has good insulation properties, prevents electrical leakage, and improves safety for the human body.
