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.

(1-1) Prior Art Conventionally, ozone has been used to deodorize, for example, the bad odor that occurs in a toilet bowl, that is, the bad odor that occurs when defecating or urinating.

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 bowl was developed in Japanese Patent Application Laid-Open No. 60 (1983).
This method has already been disclosed in Publication No. -31719.

That is, this disclosed technology incorporates an ozone deodorizing device at the rear of the toilet bowl, sucks in bad odors from an inlet, draws them into the device, contacts the ozone generated by an electric discharge in an ozone generator, and removes 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, each deodorizing flow path 6 of the ozone deodorizing device is provided with 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. It had been.

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, and therefore, if the high voltage from the high voltage generator were to leak, it could be transmitted to the human body through the case, which was extremely dangerous.

The present invention relates to an ozone deodorizing device that can solve the above problems.

(d) Means for solving the problem In the present invention, an ozone generator is interposed in the middle of the ozone treatment flow path between the inlet and the exhaust port provided in the ozone deodorizing device to remove bad odors using ozone. An ozone deodorizing device for deodorizing, characterized in that at least a high voltage generator is molded with synthetic resin.

Further, the present invention is characterized in that the ozonizer and the high voltage generator are molded with synthetic resin, and the discharge portion of the ozonizer is exposed.

(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, ozone is generated because the high voltage generator of the ozone generator is molded with synthetic resin. By improving the insulation properties of the device, it is possible to reliably prevent electrical leakage and improve safety for the human body.

Furthermore, since the ozonizer and high voltage generator of the ozone generator are molded with synthetic resin, and the discharge part of the ozonizer is exposed, high voltage is discharged from the discharge part. It can be done easily.
