Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to an ozone deodorizing device.

(B) Prior Art Conventionally, ozone has been used to deodorize, for example, bad odors generated in a toilet bowl, ie, bad odors generated during defecation and urination.

Ozone eliminates odors by oxidizing and decomposing malodorous components through its oxidizing action, and the technology to deodorize by attaching an ozonizer that generates such ozone only to the bottom of the exhaust flow path is a waste. Disclosed.

The ozone deodorizing device is installed on the side of the toilet bowl, and the ozone deodorizing device is attached to the side of the toilet, and the odor is sucked in through the inlet and drawn into the device.The ozone deodorizer is brought into contact with the ozone generated by the electric discharge action in the ozonizer, and the bad odor is broken down.・It deodorizes and discharges it to an appropriate place, such as outside the toilet bowl.

Further, in such an ozone deodorizing device, a catalyst is disposed behind the ozonizer in order to activate ozone and promote the reaction with bad odors.

(c) Problems to be Solved by the Invention However, in such toilet bowls, the ozonizer that generates ozone is disposed only at the bottom of the exhaust flow path, so the range where ozone is distributed is narrow and the ozonizer is Ozone and bad odor were not evenly mixed in the exhaust flow path because the ozone was generated unevenly on the bottom surface where ozone was located.

Therefore, it is possible to consider a method of bending the U1 air flow path vertically or horizontally to promote contact between odor components and ozone, but this method has the disadvantage of being structurally multi-layered, resulting in high cost. was.

(d) Means for Solving the Problems In the present invention, in an ozone deodorizing device in which an ozone generating section consisting of an ozonizer is installed inside an ozone flow path case, the ozonizer is placed opposite to the inner wall of the ozone flow path case. It is an object of the present invention to provide an ozone deodorizing device characterized in that the ozone deodorizing device is arranged in a shape.

The present invention is also characterized in that they are disposed opposite to each other on the ceiling wall and bottom surface of the ozone channel case.

Furthermore, the present invention is characterized in that the ozonizers are disposed oppositely on both left and right walls of the ozone flow path case.

(e) Function/Effect In this invention, the malodor passes through the ozone flow path case of the ozone deodorizing device, reaches the ozone generating part, and comes into contact with the ozone produced by the ozonizer, promoting the decomposition of the malodorous components. It is something that can be done.

In the ozone generation section, ozonizers that generate ozone by applying a high voltage are disposed facing each other on the ceiling wall and bottom surface of the ozone flow path case, so that ozone is generated in the flow path. Since ozone is generated from both the upper side and the lower side, the distribution area of ozone can be expanded and distributed over the entire flow path, and mixing and contact with malodorous components can be performed uniformly.

Therefore, the malodorous components are more easily decomposed by the oxidation effect of ozone.

Further, even when the ozonizer is attached to the left and right walls of the flow path, the malodorous components and ozone are uniformly mixed and contacted in the same way as described above.
