Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a toilet bowl equipped with an ozone deodorizing device that uses ozone (0,) to decompose odor components generated from the toilet compartment.

[Conventional technology] Ventilating the outside of the toilet bowl has been conventionally done to remove odors from outside the toilet bowl, but in recent years deodorization technology that uses activated carbon and ozone has been applied. There is. In particular, the following toilet bowls with ozone deodorizing devices have been published as ones that take advantage of the strong oxidizing power of ozone.

(1) As shown in FIG. 12, air from inside the toilet bowl containing odor components sucked in by the fan 8 and an ozone generator installed in the air passage 4 are introduced into the air passage 4 from the air passage 4b. The odor components are mixed with the ozone generated in step 1, and the odor components and ozone are reacted in the ozone reaction section 4a to oxidize and decompose the odor components and deodorize them.
A toilet bowl with an ozone deodorizing device that exhausts air to the outside of the toilet bowl (for example, see Japanese Patent Application Laid-open No. 60-31719).

(2) As shown in FIG. 13, the air outside the toilet E drawn into the air passage 4 by the fan 8 from the air passage 4b is
After mixing the ozone generated by the ozone generator 1,
Ozone base pipe 14, ozone outlet pipe 15, ozone outlet 1
A toilet equipped with an ozone deodorizing device (for example, a toilet with an ozone deodorizing device that discharges ozone-containing air to the inside of the toilet bowl via 6, and reacts ozone with odor components contained in the air inside the toilet bowl)
3-161228).

・However, in the above-mentioned toilet bowls equipped with ozone deodorizing devices, the ozone that has not been involved in the oxidative decomposition of odors is directly discharged to the outside of the toilet bowl, and if the concentration is high, it will have a negative effect on human health, and if the concentration is low, it will have a negative effect on human health. However, this has the disadvantage of giving the user a feeling of discomfort and an unpleasant odor.

Therefore, in order to prevent residual ozone from being discharged indoors, a technology has been used to decompose residual ozone using an ozone decomposition device (a device made of activated carbon, etc.) (for example, Japanese Patent Laid-Open No. 61-209665 (see official bulletin). This is about an ozone deodorizing device inside a refrigerator. After the residual ozone is decomposed by an ozone decomposition device equipped with a honeycomb-structured ozone decomposition filter, deodorized air without residual ozone is discharged into the refrigerator. It is something to do. Further, after residual ozone and residual odor components (unreacted odor components) are decomposed by using a catalyst, deodorized air without residual ozone is discharged into the refrigerator.

In other words, residual ozone is activated on the surface of the catalyst and dissociates into oxygen molecules and highly active oxygen atoms, and the odor components adsorbed on the surface of the catalyst react with the oxygen molecules, resulting in odorless or odorless ozone. Changes to a substance with less Also,
Oxygen atoms that have not had a chance to react with odor components combine with each other and are discharged as oxygen molecules, so that the air can be discharged as air with less residual ozone and residual odor components.

The catalyst is made of a composite component containing titanium, silicon, zirconium, manganese, iron, etc. If this catalyst is used in an ozone deodorization device, it will be possible to efficiently decompose residual ozone as well as residual odor components. can (for example,
(See Japanese Patent Application Laid-open No. 182032/1983).

If the above technology is applied to a toilet bowl with an ozone deodorizing device, the odor components inside the toilet bowl will be oxidized and decomposed by ozone, and the deodorized air after the oxidative decomposition will be passed through a catalyst to decompose the remaining ozone and residual odor components. It can be discharged to the outside of the toilet bowl.

With such technology, it has become possible to provide a toilet bowl with an ozone deodorizing device that can deodorize the interior of the toilet bowl without adversely affecting human health.

[Problem to be Solved by the Invention] However, in the above technology, since the ozone generator 1 or the ozone generator 1a is located in the air passage 4, the ozone generator 1a is mixed with the air sucked from inside the toilet bowl. As a result, the following issues arose.

(1) The air inside the toilet bowl becomes high-temperature air because it is flushed with water every time you use the toilet, and in the ceramic-type ozone generator 1, the ceramic-type ozone generator la is exposed to the high-temperature air, reducing the amount of ozone generated. There are many things. For example, the first
As shown in Figure 4, when the environmental conditions change from a room temperature of 20°C and a relative humidity of 40% to a room temperature of 30°C and a relative humidity of 60%, the amount of ozone generated decreases to about 1/3.

(2) In the discharge-type ozone generator 1, the amount of ozone generated changes due to changes in the temperature or relative humidity of the air in the discharge space, and especially in high-temperature environments, the insulation resistance of the discharge space decreases, making it difficult for discharge to start. , toilets equipped with ozone deodorizers often do not function properly.

(3) The ozone generator 1a is easily corroded because it is exposed to organic gas in a high-temperature environment, which often shortens the product life of the ozone generator 1.

(4) Paper dust from the toilet paper used when defecating may accumulate in the ozone generating area and impede ozone generation.

The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to be able to generate a constant amount of ozone regardless of the temperature and relative humidity inside the toilet bowl, and to eliminate ozone generators. The object of the present invention is to provide a toilet bowl with an ozone generator that is hardly corroded, has excellent durability, and has a long product life.

[Means for Solving the Problems] In order to achieve the above object, the toilet bowl with an ozone deodorizing device of the present invention has an air passageway that communicates the inside of the toilet bowl with the outside of the toilet bowl, and an air passageway that connects the air inside the toilet bowl to the outside of the toilet bowl. an ozone generator for generating ozone, and a catalyst provided near the outlet of the air passage, and the ozone generated by the ozone generator and the ozone from inside the toilet bowl are provided. The odor components in the air are oxidized and decomposed by reacting the sucked air with the air in the air passage, and the catalyst installed in the air passage decomposes the residual odor and residual odor contained in the air after the reaction. In a toilet bowl equipped with an ozone deodorizing device that decomposes ozone, an ozone generator storage box for accommodating the ozone generator is provided outside the air passage so that at least one side faces the air passage, and It is characterized in that an ozone exhaust hole is provided on the side surface facing the passage, and a ventilation hole or a ventilation pipe leading to the outside of the toilet bowl is further provided on the side surface other than the side surface where the ozone exhaust hole is provided.

An ozone generator storage box for storing the ozone generator is provided outside the air passage, and a ventilation hole or a ventilation pipe leading to the outside of the toilet and an ozone discharge are provided at appropriate locations in the ozone generator storage box. A hole is provided, and an ozone injection tube having an ozone injection hole is further provided at the ozone discharge hole so that the ozone injection hole is located within the air passage.

Moreover, it is desirable that the toilet bowl with an ozone deodorizing device has a heater for heating the air in the ozone generator storage box.

[Function] According to the toilet bowl with an ozone deodorizing device of the present invention, in the ozone generator storage box 3 disposed outside the air passage 4,
An ozone generator 1 is housed therein. Further, the ozone generator 1 and the air passage 4 communicate through an ozone exhaust hole or an ozone injection hole 5, and a fan 8 discharges the air inside the toilet bowl through the air passage 4 to the outside E of the toilet bowl. Therefore, the air pressure in the air passage 4 is lower than the air pressure (atmospheric pressure) outside the toilet bowl, which is communicated through the ventilation hole 6 or the ventilation pipe. Furthermore, the air sucked inside the toilet bowl will not flow into the ozone generator storage box 3 and adversely affect the ozone generator.

In addition, the ozone generator storage box 3 is heated by the heater 12.
By increasing the temperature of the air inside, the relative humidity is lowered,
The insulation resistance of the discharge space of the discharge type ozone generator 1 can be increased, and as a result, the discharge type ozone generator 1 can be kept in a state where it can always generate an appropriate amount of ozone even in a high temperature environment. be able to.

[Examples] Hereinafter, the present invention will be explained in more detail based on Examples.

FIG. 1(b) is a sectional view taken along the line a-a in FIG. 1(a).

In this embodiment, a box A having a substantially rectangular parallelepiped shape is provided behind the toilet seat B, and an air passage 4b for sucking air from inside the toilet bowl is provided in the rear central part of the toilet bowl C in the box A, behind the toilet bowl C. An L-shaped air passage 4 is provided on the right side of the toilet bowl so that an air passage outlet 4c for discharging the air inside the toilet bowl is arranged on the right side of the toilet bowl. There is a vent 21 near the left end of the rear side of the rectangular parallelepiped A that connects to the outside edge of the toilet bowl and sucks air from outside the toilet E, and a vent 21 that connects to the outside edge of the toilet bowl near the right end of the rear side of the rectangular parallelepiped A to suck air from outside the toilet bowl.

Note that the fan motor 9 used had a suction air volume of 20 ONL/Min.

With this level of airflow, the air containing odor components inside the toilet bowl will not be diffused to the outside of the toilet bowl, and the wind speed passing around the thighs is slow, so the user will not feel cold (or confused). At the same time, the noise of the fan 8 can also be suppressed.

Although the toilet bowl with the ozone deodorizing device configured as described above was used repeatedly, the amount of ozone generated decreased and the ozone generator 1a
Almost no corrosion was observed. It was confirmed that ammonia was decomposed by an average of 52%.

Although the catalyst 7 was used in this embodiment, an ozone decomposition device may be used instead of the catalyst 7.

Moreover, an air pipe can be provided in the ozone generator storage box instead of the ventilation hole 6.

In this embodiment, the case where there is one ozone discharge port 5 is shown, but
A plurality of them may be provided as shown in FIG. Also, the third
As shown in the figure, the ozone generator storage box 3 may be arranged to protrude from the wall of the air passage 4 so as to restrict the flow of air in the air passage 4. Further, as shown in FIG. 4, a semi-cylindrical constriction part 20 may be provided on the wall surface of the air passage 4 so as to restrict the flow of air in the air passage 4. As shown in FIG. 4, the throttle part 20 may be used as the ozone generator storage box 3.As a result of using the toilet bowl with the ozone deodorizing device configured as shown in FIGS. 4 and 5, the average ammonia content was 57%.

FIG. 10 is a circuit diagram of the ozone generator 3, transformer 2, and heater 12. As shown in FIG. 10, the heater 12 was placed downstream of the vent hole 6 so that the air warmed by the heater 12 passed through the ozone generator 1 (discharge type).

In a high-temperature environment, the ozone generator storage box 3
The relative humidity must be lowered by increasing the temperature with the heater 12.

For example, when the temperature of the air inside the ozone generator storage box 3 is 20°C and the relative humidity is 80%, the heater 1
In order to make the relative humidity 50% in 2, it is necessary to raise the temperature of the air inside the ozone generator storage box 3 to about 28°C. On the other hand, if the temperature of the air in the ozone generator storage box 3 is raised too much, the amount of ozone generated decreases as shown in FIG. Therefore, in the embodiment, the heater 12 was set to raise the temperature of the air inside the ozone generator storage box 3 by about 5'C to 8C above the temperature outside the toilet bowl E.

In this embodiment, the heater 12 is arranged in the ozone generator storage box 3, but the heater 12 can also be installed in the ozone generator 1 itself.
