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.

However, if the amount of ozone is set to correspond to the strongest odor, even if the odor is weak or almost non-existent, the amount required to deodorize the strongest odor will be the same. of ozone will be generated.

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 problems.

(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. , an ozone deodorizing processing flow path with an outlet at the other end opened into the toilet space, an ozone generation section interposed within the ozone deodorizing processing flow path, and an ozone deodorizing processing flow path provided near 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 comprises a spraying section for spraying an ozone decomposition liquid.

Further, the present invention is characterized in that the ozonolytic liquid sprayed from the spraying section is an alkaline liquid.

(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.

If excess ozone remains in the exhaust gas after deodorization treatment, ozone decomposition liquid is sprayed from the spraying section near the exhaust port, and the remaining ozone in the exhaust gas after deodorization treatment is dissolved in this liquid. This reduces the amount of ozone in the exhaust gas.

In addition, since the ozone decomposition liquid is dispersed into the exhaust gas from the spray section in the form of fine mist, the contact area with ozone is increased, and ozone can be smoothly dissolved.

Further, by spraying an alkaline liquid from the spraying section, ozone can be dissolved in the liquid and decomposed, thereby reducing the amount of ozone remaining in the exhaust gas.

Therefore, even if excess ozone remains in the exhaust, the ozone deodorizing device maintains the ozone concentration in the exhaust at a constant level by dissolving and decomposing the ozone in the sprayed liquid at the outlet of the ozone deodorizing flow path. This can be suppressed to below the specified value, 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. An ozone deodorizing device C is removably attached to the machine.

Furthermore, in addition to the ozone deodorizing device c, a private part cleaning device including a jet nozzle 10 and a low tank (none of which are shown) are integrally arranged inside the functional part casing B.

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,

is provided.

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, and the cylindrical body 11 is located inside the mounting frame F. A long ozone deodorization processing channel G is formed.

Both ends of the cylindrical body 11 form a suction part 12 and a discharge part 13, respectively. (See Figure 2) Through the internal space Q of the toilet main body T
It communicates with

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.

Further, by heating the ozonizer 18 with the heater 18a, 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 unit 20 has semicircular rectifiers vi21 and 22 provided on the upper and lower surfaces of the ozone deodorizing flow path G at regular intervals in the axial direction.

Due to the rectification @21, 22 and the rectifier plate 12a provided at the bottom of the suction part 12 of the cylindrical body 11, the bad odor that has flowed into the ozone deodorization processing flow path G from the ozone deodorization device equipped toilet bowl A is
It is effectively mixed with ozone generated from the ozonizer 18, and can promote the deodorizing effect in the ozone deodorizing process 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 and 24.
are formed in series, and these catalyst installation spaces 23.2
Catalysts 25 and 26, which can be replaced periodically, are removably disposed within the chamber.

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.

Supports include alumina, silica, alumina silica, bentonite, diatom, silicon carbide, titania, zirconia, magnesia, kobuilite, mullite,
Examples include activated carbon, and more preferred examples include binary composite oxides consisting of titanium-silicon, binary composite oxides consisting of titanium-zirconia, and ternary composite oxides consisting of titanium-silicon-zirconia. It will be done. Further, the shape of the catalyst is not particularly limited, and honeycomb, granular, cylindrical, and other various shapes can be used.

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.

Further, in the present invention, a spray nozzle 27 is disposed in the discharge section 13 as a spray section for ozone decomposition liquid, and the liquid from the nozzle 27 is used to decompose ozone contained in the exhaust gas after deodorizing treatment. That's what I do.

In this embodiment, as shown in FIGS. 3 and 4, a water liquid tank 27a and a pump 27b are connected to the spray nozzle 27, and water is supplied from the spray nozzle 27 by driving the pump 27b. It is sprayed in a mist form.

In this embodiment, as shown in FIG. 3, a liquid tank 27a and a pump 27b are housed in the rear part of the functional part casing B, and a lid body 28 is detachably attached to the rear part of the casing B. A pump 27 is provided at the bottom of the inner surface of the lid body 28.
A liquid tank 27a is installed.

By removing the lid 28, liquid is replenished into the liquid tank 27i1.

Note that 29 indicates a pipe connecting the spray nozzle 27 and the pump 27b.

Further, the spray nozzle 27 is connected to the ceiling surface 1 of the discharge section 13.
3a, and is attached with its tip end slightly inclined toward the discharge port 17 provided on the lower surface of the discharge portion 13.

The atomized liquid sprayed from the spray nozzle 27 is
A turbulent flow is created within the discharge section 13 to mix the ozone in the exhaust and the liquid.

Furthermore, since this liquid is sprayed in the form of a fine mist, the contact area with ozone is increased, and ozone can be completely dissolved.

Moreover, in this embodiment, the exhaust blower 16 in the exhaust section 13
The atomized liquid and the exhaust gas are diffused by the atomized liquid, and the liquid and the exhaust gas are mixed together.

Further, a control unit (2) is connected to the pump 27b for driving the spray nozzle 27, and the control unit I controls the drive of the pump 27b.

With this configuration, by spraying the liquid from the spray nozzle 27 into the discharge part 13, the ozone remaining in the exhaust gas is dissolved in the liquid and decomposed, so that the ozone concentration can be reduced.

Further, by spraying an alkaline liquid or an aromatic agent in addition to water as a liquid for decomposing ozone from the spray nozzle 27 of the present invention, ozone decomposition is effectively performed.

In addition, as another embodiment, an ultrasonic vibrator or the like can be considered as the spray section.

Further, in this embodiment, the liquid is sprayed from the spray nozzle 27 in a fan shape or in a straight line, or intermittently at regular intervals.

Further, a turbulent flow 130 can be installed in the exhaust section 13, and the turbulent flow plate 30 can form a turbulent flow that mixes the liquid from the spray nozzle 27 and ozone in the exhaust section 13.

In addition, two hoses connected inside the toilet main body T are connected to the exhaust port 17 for discharging the exhaust gas after deodorization treatment with ozone, and the liquid from which the ozone has been decomposed is pumped through the same hose into the toilet main body T.
I am trying to drain water inside.

Hereinafter, with reference to FIG. 4, a description will be given of a method for deodorizing bad odors generated in the toilet main body T using the ozone deodorizing device 2c having the above configuration.

First, when a person sits on the toilet seat R of the toilet bowl A equipped with an ozone deodorizing device, the seating sensor S installed at the rear of the toilet seat R sends a detection output to the control unit ■, and the drive output from the control unit I activates the exhaust pro 916. 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 G.

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 flow path G, and the ozone mixing part 2
At 0, it is effectively mixed with ozone and deodorized.

Further, since catalysts 25 and 26 are disposed downstream of the ozone mixing section 20, when the ozone passes through the catalyst, the mixing of the odor and ozone is further promoted, and the deodorization process is further promoted. It turns out.

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.

In addition, in this embodiment, a spray nozzle 27 is attached to the discharge section 13 as a spray section for ozone decomposition liquid, and the ozone in the exhaust gas is dissolved in the liquid from the nozzle 27 and decomposed. Since the amount of ozone in the exhaust air is reduced, the ozone concentration in the exhaust gas is always kept below a certain value, for example, 0.000000000000000000000000000000000000000000000000000000000 though lppm or less, and furthermore, ozone odor does not occur. O2 can be suppressed to less than 2 ppm, ensuring sufficient safety for the human body, and completely eliminating the discomfort caused by ozone odor when using the toilet.

Further, by optimally controlling the amount of ozone generated, the amount of electric power required to drive the ozone generating section H can be reduced, and energy saving can be achieved.

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 I
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.
