Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ozone deodorizing device in which an odor passage and an ozone generation passage are provided separately.

[0002]

2. Description of the Related Art Conventionally, in a deodorizing device using ozone,
An ozone generator and a catalyst are installed in the odor passage to adsorb the odor component to the catalyst and decompose the odor component by the ozone's oxidizing action to deodorize, but the odor component reacts with ozone. 3H ₂ S + 4O ₃ → 3H ₂ SO ₄ 3CH ₃ SH + 7O ₃ → 3CO ₂ + 3H ₂ SO ₄ + 3H ₂ O, sulfuric acid (H ₂ SO ₄ ) is formed, and 3NH ₃
+ 4O ₃ → 3HNO ₃ + 3H ₂ O like nitric acid (HNO
₃ ) to form.

[0003]

As described above, when there is an ozone generator in the odor passage for forming sulfuric acid or nitric acid, these acids damage the electrodes of the ozone generator and reduce ozone generation efficiency. In addition, since the place where the odor is generated is an atmosphere with high humidity such as in a toilet bowl, this high humidity air will flow through the odor flow path together with the odor. The ozone generator provided in the middle of the process generates ozone in an atmosphere of high humidity, which is a cause of further lowering the ozone generation efficiency.

[0004]

According to the present invention, first, the air containing odor is sucked through the odor suction passage, the odor components are adsorbed by the catalyst arranged in the common passage, and the air is then placed in the middle of the air suction passage. By operating the provided ozone generator, air is sucked together with the generated ozone, and the odorous components previously adsorbed on the catalyst are decomposed into ozone to deodorize.

At this time, the odor flows through the odor intake passage, and the ozone flows through the air intake passage together with clean air in a different passage from the odor. The acid of the ozone generator does not damage the electrodes.

In particular, if an opening / closing lid is provided for each of the intake passage for inhaling odors and the air intake passage for passing ozone, the odors will be closed when the odors are inhaled. Can be prevented from coming into contact with the ozone generator, and when ozone is circulated from the air suction passage, the odor suction passage is closed and the air suction passage is opened. Ozone generated from the generator can decompose the odor component adsorbed on the catalyst regardless of the flow path in the odor, the humid air containing the odor component does not come into contact with the ozone generator, and the ozone generation efficiency It becomes possible to prevent the decline.

Further, if the start end of the odor intake passage is opened inside the toilet bowl and the start end of the air intake passage is opened outside the toilet bowl, the humidified air containing the odor inside the toilet bowl affects the ozone generator at all. Without this, ozone is generated in the process of inhalation and circulation of clean air outside the toilet bowl, it is possible to prevent a decrease in ozone generation efficiency, and it is possible to improve the function of the ozone deodorizing device attached to the toilet bowl.

[0008]

According to the present invention, an odor intake passage and an air intake passage are formed in different passages, and the start ends of the passages are joined to communicate with a common passage. The present invention provides an ozone deodorizing device in which an ozone generator is provided in the middle of the air intake passage and a catalyst is provided in the middle of the common passage, and an odor intake passage and an air intake passage are also provided. An ozone deodorizing device having an odor opening / closing lid and an air opening / closing lid respectively, and the start end of the odor suction passage should be opened inside the toilet bowl, and the tip of the air suction passage should be opened outside the toilet bowl.

In addition, the air intake passage Y has a starting end opening at the air intake port 10 near the inner wall of the lower side of the casing or the left side sleeve, and forms the odor intake passage X and the side wall of the deodorizing duct 7. An air intake flow path Y for inhaling and circulating air is formed with the side wall of the.

As shown in the block diagram of FIG. 4, the basic configuration of the ozone deodorizing apparatus M of the present invention is such that the odor suction flow passage X and the air suction flow passage Y are formed in different flow passages, and each flow is formed. The ends of the passages merge to communicate with the common passage Z, and the ozone generator G
Is disposed in the air intake passage Y, and the intake fan F and the catalyst S are sequentially disposed in the common passage Z.

The odor intake passage X and the air intake passage Y

In the ozone deodorizing device thus constructed, the odor generated in the bowl portion a of the toilet by operating the intake fan F flows through the odor intake passage X and the catalyst in the common passage Z. At S, the odorous component is adsorbed on the catalyst S. After that, when ozone is generated by operating the ozone generator G, the ozone reaches the catalyst S of the common flow path Z together with the clean air sucked from the opening of the air suction flow path Y, and the ozone is discharged.

Moreover, one of the odor opening / closing lid x provided in the odor intake passage X and the air opening / closing lid y provided in the air intake passage Y is opened according to the use time of each passage, and one is opened. If it is controlled to close the lid, for example, the odor opening / closing lid x should be opened and the air opening / closing lid y should be closed while the odor in the toilet is being sucked from the odor suction passage X. Thus, the air containing odor is adsorbed by the catalyst S without contacting the ozone generator G at all. Therefore, the electrode of the ozone generator G is not damaged by the sulfide contained in the odor, and furthermore, the air containing the odor is sucked from the inside of the toilet bowl to become humid air, which lowers the ozone generation efficiency. Although hindering, such moist air does not flow into the air intake passage Y, so that the ozone generator G
It is possible to maintain good ozone generation efficiency.

After the odorous component is adsorbed on the catalyst S, the odor opening / closing lid x is closed and the air opening / closing lid y is opened, so that clean air outside the toilet passes through the air intake passage Y. The ozone is sucked into the common flow path Z, and the ozone from the ozone generator G provided in the air intake flow path Y reaches the catalyst together with the clean air and decomposes the adsorbed odorous component into ozone. In this state, the humid air does not flow into the ozone generator G in the air intake passage Y, so that ozone is not generated in an atmosphere of high humidity and the ozone generation efficiency is improved. is there.

In the present invention, since the odor intake passage X and the air intake passage Y are independent of each other in this way,
