Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention provides a method for effectively deodorizing odor generated in a toilet bowl by ozone, as well as decomposing residual ozone in exhaust gas. The present invention relates to a toilet bowl with an ozone deodorizing device having a treatment tank.

(b) Conventional technology In recent years, it has become known that ozone has a strong deodorizing effect due to its strong oxidizing effect.As a result, as in other technical fields, ozone is also used for the purpose of deodorizing , Japanese Unexamined Patent Publication No. 60-31719 has proposed a toilet bowl with a built-in ozone generator.

In other words, the toilet bowl described in the same publication has an ozone deodorizing device built into the main body installed at the rear of the toilet seat, and the bad odor generated in the toilet bowl is sucked into the lyozone deodorizing device through a suction port opened in the toilet bowl. The ozone generated by the discharge action of the ozone deodorizing device decomposes and deodorizes bad odors, and then the deodorized air can be discharged into the toilet.

(c) Problems to be solved by the invention However, such toilets still had the following problems to be solved.

That is, the amount of ozone generated by the ozone generator provided in the toilet bowl is set to an amount that can deodorize the strongest odor generated inside the toilet bowl.

Therefore, when a strong odor is generated during defecation, a sufficient amount of ozone generated by the ozone generator reacts with the odor, thereby effectively deodorizing it.

However, in the ozone generating section described above, even when the malodor is weak or almost absent, the same amount of ozone is generated as the amount required to deodorize a strong malodor.

However, since only a portion of the ozone generated by the ozone generator reacts with bad odors, the ozone concentration in the exhaust air after deodorizing treatment becomes extremely high, causing problems for human safety such as headaches and eye irritation. It becomes a problem.

The present invention relates to a toilet bowl with an ozone deodorizing device having a residual ozone treatment tank that can solve the above problems.

(d) Means for Solving the Problems The present invention provides an ozone deodorizing system in which a suction port at one end is opened into the internal space of the toilet bowl in a toilet bowl equipped with an ozone deodorizing device that deodorizes bad odors generated in the toilet bowl using an ozone deodorizing device. An ozone generator and an exhaust blower are located in the middle of the processing flow path, and an exhaust section at the rear end of the ozone deodorization processing flow path is
A toilet bowl with an ozone deodorizing device is provided, which has a residual ozone treatment tank which is connected to a treatment tank storing a highly concentrated alkaline aqueous solution and blows exhaust gas into the alkaline aqueous solution.

Further, the alkaline aqueous solution is characterized in that it is lime water or an aqueous solution containing sodium hydroxide.

(E) Functions and Effects In the present invention, when defecating using this toilet, the bad odor is sucked through the suction port opened in the internal space of the toilet main body and reaches the ozone deodorization processing channel, where the bad odor is removed by ozone generation. The ozone comes into contact with the ozone generated from the ozone, and is deodorized by the ozone's deodorizing action. After the deodorizing process, some ozone remains in the exhaust gas, and the exhaust gas is sent to the exhaust section at the rear end by an exhaust blower installed at the rear of the ozone deodorizing process flow path. is blown into a processing tank containing water.

Then, the exhaust gas blown into the processing tank is ejected into the alkaline aqueous solution and rises in the alkaline aqueous solution in the form of bubbles.

Therefore, residual ozone in the exhaust gas is decomposed by the alkaline aqueous solution and completely treated. and,
The exhaust gas from which ozone has been treated in the treatment tank is discharged into the toilet space.

As described above, according to the present invention, the bad odor generated during defecation is completely deodorized by generating ozone in the ozone deodorizing treatment flow path, and then the exhaust gas in which some ozone remains is removed to a high temperature. Since the ozone is blown into a concentrated alkaline aqueous solution to undergo the q minute treatment, no odor or ozone remains in the exhaust gas, and safety to the human body can be sufficiently ensured.
