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. , 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 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 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 have 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 occurs during defecation, a sufficient amount of ozone generated by the ozone generator reacts with the odor and deodorizes effectively. The ozone concentration in the exhaust gas has also been sufficiently reduced, and it is considered that there are no safety issues for the human body.

In this way, if the amount of ozone is set for the strongest odor, even if the odor is weak or almost absent, the same amount of ozone as is required to deodorize the strongest odor will be used. will occur.

In this case, only a portion of the ozone generated by the ozone generator will react with the odor.
The ozone concentration in the exhaust gas after deodorizing treatment becomes extremely high, causing safety issues for the human body such as headaches and eye irritation.

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

(d) Means for Solving the Problems The present invention provides a toilet bowl with an ozone deodorizing device that deodorizes bad odors generated in the toilet bowl using an ozone deodorizing device. In the internal space, an ozone deodorizing processing flow path having an outlet at the other end opened into the toilet space, an ozone generating section interposed within the ozone deodorizing processing flow path, and a vicinity of the outlet of the ozone deodorizing processing flow path. The present invention relates to a toilet bowl equipped with an ozone deodorizing device, characterized in that it is configured with an ultraviolet irradiation device installed in the toilet bowl.

(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 interior space of the toilet bowl and reaches the ozone deodorization processing flow path, where the bad odor is generated from the ozone generating part. The air is deodorized by the deodorizing action of ozone, and the deodorized air is discharged from the outlet at the other end.

At this time, near the outlet of the ozone deodorizing flow path,
The ozone remaining in the exhaust gas after deodorization treatment with ozone is
Ultraviolet rays are irradiated from an ultraviolet irradiation device installed near the discharge port, and the ultraviolet rays decompose the waste into oxygen and active oxygen.

That is, if the amount of ozone remaining in the exhaust gas is excessive after deodorization treatment with ozone, the ozone is decomposed into oxygen and active oxygen by ultraviolet rays from the ultraviolet irradiation device.
This reduces the amount of ozone and maintains the ozone concentration in exhaust gas at an appropriate level.

Therefore, the ozone deodorizing device uses an ultraviolet irradiation device to decompose ozone after deodorizing treatment with ozone.
The ozone concentration in the exhaust gas can be kept below a certain value at all times, and safety to the human body can be sufficiently ensured.

(f) Examples The present invention will be specifically described below with reference to examples shown in the accompanying drawings.

Figures 1 and 2 show the overall structure of a toilet bowl A with an ozone deodorizing device according to the present invention. Casing B
An ozone deodorizing device C is removably installed inside.

In addition, inside the functional part casing B, there is an ozone deodorizer WIC.
In addition, a local cleaning device including a spout nozzle 10 and a low tank (none of which are shown) are integrally provided.

Furthermore, in an example of the rear part of the toilet seat R, detecting that the user has sat on the toilet seat R and that the user has left the toilet seat R,
As will be described later, a seating sensor S is provided which adjusts the amount of ozone generated from the ozone generating section H via the control section 1. On the other hand, on the other side of the rear part of the toilet seat R, as shown in Figure 1, a backup controller U is attached that can be used in the event that the remote controller P that controls the private parts cleaning device etc. attached to the wall fails. There is.

Hereinafter, with reference to FIG. 3, a specific configuration of the ozone deodorizing device C, which constitutes the gist of the toilet bowl A with an ozone deodorizing device according to the present invention, will be explained.

As shown in the figure, a long cylindrical body 11 is provided in a slightly inclined state in a mounting frame F that is detachably provided at the bottom of the functional part casing B. A long ozone deodorization processing channel G is formed.

Both ends of the cylindrical body 11 form a suction part 12 and a peak part 13, respectively, and the suction part 12 has a communication channel 14 formed in its upper part and a suction opening in the toilet bowl A. It communicates with the internal space Q of the toilet main body T through the opening 15 (see FIG. 2).

On the other hand, the exhaust section 13 is connected to an exhaust blower 16,
The exhaust blower 16 has an exhaust port 17 formed on its lower surface.

In addition, an ozonizer 18 with a heater 18a, which constitutes a main part of the ozone generating section H, is disposed in the center of the ozone deodorizing flow path G formed in the cylindrical body 11.

The ozonizer 18 is connected to a high pressure generator 19 provided on the outer peripheral surface of the cylindrical body 11.
9 is connected to a control unit I installed on the mounting frame F.

With this configuration, based on the drive output from the control unit I, the high-pressure generator 19 can apply a high voltage to the ozonizer 18 to generate ozone in the ozone deodorizing flow path G.

Also, the ozonizer 1 is heated by the heater 18a and
8 can be dried and the generation of ozone can be promoted.

Further, in the ozone deodorizing flow path G, an ozone mixing section 20 is formed downstream of the ozonizer 18.

The ozone mixing section 20 has semicircular current plates 21 and 22 provided on the upper and lower surfaces of the ozone deodorizing treatment flow IC at regular intervals in the axial direction.

Due to the rectifying plate 2L22 and the rectifying plate 12a provided at the bottom of the suction part 12 of the cylindrical body 11, the odor flowing from the ozone deodorizing device equipped toilet bowl A into the ozone m back processing channel G is removed from the ozonizer 18. It is effectively mixed with ozone and can promote the deodorizing effect within the ozone deodorizing treatment channel G.

In addition, in the ozone deodorization processing flow path G, on the downstream side of the ozone mixing section 20, there are first and second catalyst installation spaces 23, 2.
4 are formed in series, and these catalyst installation spaces 23.
Catalysts 25 and 26, which can be replaced periodically, are removably disposed within the catalyst 24.

The second catalyst installation space 24 communicates with the discharge section 13 .

The catalysts 25 and 26 may have various compositions and forms, and are preferably those in which a predetermined metal or metal oxide is supported on a carrier. These metals or metal oxides include manganese, iron, nickel, cobalt, silver, platinum, palladium, rhodium, chromium, molybdenum,
Examples include lead, tungsten, copper, vanadium, etc., which may be used alone or in combination.

In addition, the shape of the catalyst is not particularly limited, such as honeycomb shape,
Granular, cylindrical, and other various shapes can be applied.

Since such catalysts 25 and 26 promote the decomposition of ozone into oxygen and active oxygen, it is possible to further promote the deodorizing effect caused by the above-mentioned mixing of ozone and bad odor.

Furthermore, in the present invention, an ultraviolet irradiation device 27 for decomposing ozone contained in the exhaust gas after deodorization treatment is provided in the exhaust section 13, and the device 27 is connected to the control section (2). 1 controls the irradiation of ultraviolet rays.

As the ultraviolet irradiation device 27, for example, an ultraviolet lamp 28 is used, and the ultraviolet lamp 28 irradiates the entire exhaust section 13 with ultraviolet rays to ensure that ozone is decomposed.

In this embodiment, ultraviolet light having a wavelength of 253.7 nm is intensively irradiated from the external variable lamp 28, and ozone is decomposed by this ultraviolet light.

Then, the ozone is irradiated with ultraviolet light from the ultraviolet lamp 28, and the ultraviolet light decomposes the ozone into oxygen and active oxygen (active oxygen connects with active oxygen to become oxygen), reducing the amount of ozone remaining in the exhaust gas. can be done.

Hereinafter, with reference to FIG. 4, a description will be given of a method for deodorizing a bad odor generated in the toilet main body T using the ozone deodorizing apparatus C having the above configuration.

First, when a person sits on the toilet seat R of the toilet bowl A with an ozone deodorizing device, the seating sensor S installed behind the toilet seat R sends a detection output to the control unit I, and the exhaust blower 16 is activated by the drive output from the control unit At the same time, the high voltage generator 19 generates a high voltage, which is applied to the ozonizer 18 to generate ozone in the ozone deodorizing flow path C.

As a result, the bad odor generated in the internal space Q of the toilet main body T is sucked into the ozone deodorization processing channel C, and the ozone mixing section 2
At 0, it is effectively mixed with ozone and deodorized.

Further, catalysts 25 and 26 are provided downstream of the ozone mixing section 20.
, the mixing of bad odor and ozone is further promoted when the ozone passes through the catalyst, and the deodorizing process is further promoted.

Thereafter, the completely deodorized exhaust gas passes through the exhaust section 13 and the exhaust blower 16, and is discharged from the exhaust port 17 into the toilet space.

Furthermore, in this embodiment, the residual ozone in the exhaust gas is decomposed into oxygen by the ultraviolet irradiation device 27 provided in the exhaust section 13, thereby reducing the amount of ozone in the exhaust gas and keeping the ozone concentration in the exhaust gas at a constant value. Below, for example, the concentration can be suppressed to below the industrial hygiene allowable concentration of 0.1pp-, and furthermore, to below o, ozpρ-, which does not generate ozone odor, ensuring sufficient safety for the human body, and making it easier to use when using the toilet. completely eliminates the discomfort caused by ozone odor.

Note that when the user leaves the seat after using the toilet, the seating sensor S detects this movement, and based on the detection output, the control unit
stops the operation of the exhaust blower 16 and the ozone generator H.

Although the toilet bowl with an ozone deodorizing device according to the present invention has been described above based on the embodiments shown in the attached drawings, the following modifications of the present invention are also possible.

That is, in the embodiment shown in FIG. 3, the cylindrical body 11 is made of an ozone-resistant (oxidation-resistant) material such as Teflon, fluorocarbon resin, or silicone resin, or an inorganic material such as ceramic, or a metal material. I can do it.

Moreover, the ozone deodorizing device C is not limited to the inside of the functional part casing B, but can also be provided at other locations, for example, on the side or front of the toilet main body T.

Furthermore, the ozone deodorizing device C according to the present invention can be applied to living spaces other than the above-mentioned toilets, such as kitchens, washrooms, bathrooms, living rooms, etc., as appropriate.
