Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a toilet bowl with an ozone deodorizing device that can effectively deodorize bad odors generated in the toilet bowl by ozone.

(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. 80-31719 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 odor generated in the toilet bowl is sucked into the ozone deodorizing device through a suction port opened in the toilet bowl. The ozone generated by the discharge action of the ozone deodorizing device deodorizes bad odors by 9 minutes, and then the deodorized air can be discharged into the toilet.

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

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

Therefore, when a strong bad odor occurs during defecation, a sufficient amount of ozone generated by the ozone generator reacts with the bad odor, making it possible to effectively deodorize.

Moreover, the ozone concentration in the exhaust gas after deodorization treatment was also sufficiently reduced, and it is considered that there is no problem in terms of safety for the human body.

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, some of the ozone generated by the ozone generator does not react with the odor, so the ozone concentration in the exhaust air after deodorization increases significantly, causing problems for human health such as headaches and eye irritation. It becomes a problem.

Furthermore, even though a small amount of ozone can be used to deodorize bad odors, a surplus of ozone is generated, which poses an economical problem.

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

(d) Means for Solving the Problems In the present invention, in a toilet bowl equipped with an ozone deodorizing device that deodorizes bad odors generated in the toilet bowl using an ozone deodorizing device, the ozone deodorizing device is connected to the suction port at one end of the toilet bowl body. i
This includes an ozone deodorizing processing flow path with an outlet at the other end opened into the toilet space, an odor sensor for detecting malodor concentration installed at the starting end of the ozone deodorizing processing flow path, an ozone generating section, and an odor sensor. It is an object of the present invention to provide a toilet bowl equipped with an ozone deodorizing device, characterized in that it is comprised of a control section which controls an ozone generating section by nine outputs from the present invention.

(E) Function/Effect In the present invention, when defecating using this toilet bowl, the bad odor is sucked through the suction port opened in the internal space of the toilet bowl body and reaches the ozone deodorization processing channel, where the bad odor is detected by the odor sensor. The concentration output detected by the odor sensor is transmitted from the odor sensor to the control section, which controls the ozone generation section and adjusts the amount of ozone generation.

When the concentration of bad odor is above a certain level, the amount of ozone generated from the ozone generating part is increased, and conversely, when the concentration of bad odor is below a certain level, the amount of ozone generated is decreased and brought into contact with the bad odor. be.

The bad odor is then deodorized by the deodorizing effect of ozone.
The exhaust gas after the deodorization process is discharged from the outlet at the other end with a small amount of ozone.

That is, the amount of ozone generated from the ozone generator is automatically controlled according to the concentration of the malodor, so that the amount of ozone that always matches the concentration of the malodor is generated.

Therefore, when a strong odor is generated during defecation, a large amount of ozone can be generated in the ozone generator for effective deodorization, whereas when the odor is low or almost absent, The ozone generator generates a sufficient amount of ozone to deal with such bad odors.

In this way, depending on the intensity of the odor, the ozone deodorization device will
Since the necessary amount of ozone can be generated for deodorization processing, the ozone concentration in exhaust gas can be kept below a certain value at all times, ensuring sufficient safety for the human body, and ozone The deodorizing device can be used economically.
