CONSTITUTION:An ozone deodorizer M is provided halfway in a channel between a suction port 9 opened inward of a bowl section (a) of a stool body A and an exhaust port 10 opened inward or outward of the stool body A. After that, the channel in the vicinity of an ozone generating section 15 in the ozone deodorizer M is deformed such as a bent channel X, spiral channel, reduced diametral and enlarged diametral channels, etc. Malodorous air and ozone are mixed well during the passage through the deformed channel, and the oxidation and disintegration of the odor are promoted.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a toilet bowl equipped with an ozone deodorizing device.

(B) Prior Art Conventionally, ozone has been used to deodorize bad odors generated in toilet bowls, for example, bad odors generated during feces and urination.

Ozone eliminates odors by oxidizing and decomposing malodorous components through its oxidizing action, and the technology for deodorizing by incorporating such an ozone generator into a toilet bowl is disclosed in Japanese Patent Laid-Open No. 60-317.
It has already been disclosed in Publication No. 19.

That is, this disclosed technology has an ozone deodorizing device built into the rear of the toilet bowl, sucks in bad odors through a suction port, draws them into the device, makes them come into contact with ozone generated by an electric discharge in an ozone generating section, and decomposes the bad odors. Deodorize and place in a suitable place.
For example, it is discharged outside the toilet bowl.

(c) Problems to be Solved by the Invention However, in such toilet bowls, the oxidation and decomposition of malodorous components cannot be carried out quickly, especially if ozone and malodorous air are not sufficiently contacted or mixed.

Therefore, in order to promote contact between the ozone and the foul-smelling air, it is possible to consider a technique in which a mixing chamber is provided and the mixture is stirred and mixed using a special device. This has disadvantages in that it becomes narrow or even obstructs the flow of air, making it useless for quick elimination of bad odors, and that the structure is complicated and the cost is high.

(d) Means for Solving the Problems In the present invention, an ozone deodorizing device is installed in the middle of the flow path between the inlet opening toward the inside of the bowl portion of the toilet bowl body and the exhaust port opening inside or outside the toilet bowl body. In a toilet bowl that can deodorize the odor inside the toilet bowl by interposing ozone, the flow path near the ozone generating part of the ozone deodorizing device can be changed to a bent flow path, a spiral flow path, or a converging/expanding flow path. It is an object of the present invention to provide a toilet bowl equipped with an ozone deodorizing device which is designed to improve the contact between ozone and bad odor by deforming the passageway, etc.

(E) Function/Effect In this invention, the ozone deodorizing device installed in the toilet bowl allows the bad odor generated in the toilet bowl to come into contact with ozone from the inlet to the outlet via the ozone deodorizing device, and remove the bad odor components. It can promote decomposition.

Since the flow path near the ozone generation part is in a deformed state, the ozone generated in the ozone generation part and the sucked-in foul-smelling air are separated from each other by the deformed flow path as they flow through the flow path. As the mixture is repeatedly inverted within the chamber, more of the malodorous components are subject to the oxidizing action of ozone and are more easily decomposed.

In particular, the contact between odor and ozone can be reduced by making the flow path near the ozone generation part a bent flow path, a spiral flow path, or a narrow/expanded flow path with alternately narrowed and widened diameters. This can further promote the oxidation and decomposition of bad odors.

(F) Embodiment An embodiment of the present invention will be described in detail based on the drawings. Fig. 1 is an overall perspective view showing the toilet bowl of the present invention. A sanitary cleaning device (B) for cleaning private parts is arranged, and a functional casing (1) of the device (B) is equipped with a toilet seat (2) and a toilet lid (3) that can be opened and closed.

Inside the casing (1), a hot water tank, a valve unit, etc. for supplying hot water for washing private parts are arranged, and a private part that moves forward and backward toward the ball part (a) of the toilet main body (A) is arranged. It is equipped with a cleaning nozzle (4).

In addition to this private part cleaning function, it is also equipped with a hot air fan (5) and a hot air duct (6) for drying, as will be described later.

Furthermore, apart from the hot air duct (6) of the hot air fan (5), a deodorizing duct (7) is provided near the duct (6), and the deodorizing duct (7) As shown in FIG. 2, it extends into the functional part casing (1) at the left end and communicates with the ozone deodorizing device (M).

(1-2) in the figure shows the right side oil section.

As shown in FIG. 5, a deodorizing duct (7) is installed below the hot air duct (6).
7) has a suction port (9) at its tip opening slightly downward into the ball part (a) of the toilet main body (A), and from the suction port (9), the middle part (1- 3) to the center of the left oil section (1-1), and the terminal end is connected to the ozone deodorizing device (M).

[7] An exhaust port (10) is opened in the final flow path of the ozone deodorizing device (M), and the exhaust port (10) is formed in the left oil part (1-1) of the casing. It opens on the rear side of the hanging chamber case (11).

In this way, the flow path for deodorization is the entire flow path from the intake port (9) to the exhaust port (10), and the ozone deodorization device (M) is interposed in between. The deodorizing device (M) is built into the chamber case (!I).

Here, regarding the ozone deodorizing device (M), the device (M) is equipped with a fan channel case (13) housing a suction fan (12) on the upstream side of the channel.
The end of the deodorizing duct (7) is connected to the right side wall of the
The lower wall of the case (13) is connected to the upper wall of the starting end of the cylindrical ozone flow path case (14), and the terminal opening of the ozone flow path case (■4) is connected to the exhaust port (lO ) is formed.

The inside of the duct and the case from the deodorizing duct (7) to the fan flow path case (13) and the ozone flow path case (14) form a flow path for odor and deodorizing air. .

Further, in the ozone flow path case (■4), an ozone generating section (15) is arranged near the lower side of the fan flow path case (13), and a catalyst (16) is arranged on the lower side of the flow path. is installed.

The ozone generator (15) is an ozonizer (17).
and a heater (18), and the ozonizer (17) is connected to a high voltage generator (19) provided on the outer surface of the ozone channel case (14). ) is connected to the control unit, and the ozonizer (
A heater (18) heats the ozonizer (17) to promote ozone generation by applying a high voltage to the ozonizer (17).

The ozone generating section (15) described above may take various forms, and preferred examples thereof are shown in FIGS. 8A, 8B, 8C, and 8D.

That is, the ozonizer (17) has a ceramic substrate (
It is formed by providing a net-like ozone generating electrode (17b) on the front surface of 17a) and providing a plate-like ozone generating electrode (17c) on the back surface.

On the other hand, the heater (18) is formed as a ceramic plate (18b) in which a heater electrode (18a) is embedded, and the plate (18b) is integrated with the ceramic substrate (17a) of the ozonizer (17) by adhesive. are connected.

In addition, the heater electrode (18a) is an ozonizer (■7
) may be directly buried in the ceramic substrate (17a), in which case the ozone generator equipped with a heater ([5
) can be made compact.

Furthermore, the catalyst (16) disposed on the downstream side is
It promotes the decomposition of ozone into oxygen and active oxygen, thereby promoting the deodorizing effect of mixing ozone and bad odor.

The catalyst (1B) may have various compositions and forms, and is preferably one in which a predetermined metal or metal oxide is supported on a carrier. These metals or metal oxides include manganese, iron, nickel, cobalt, silver,
Examples include platinum, palladium, rhodium, chromium, molybdenum, lead, tungsten, copper, and vanadium, which may be used alone or in combination.

As a carrier, alumina, silica, alumina-silica,

Further, the shape of the catalyst is not particularly limited, and honeycomb, granular, cylindrical, and other various shapes can be used.

17, the catalyst (16) is formed into a rectangular shape as shown in FIG. There are those in which eyes are formed, and those in which a large number of narrow sections are formed by interposing a wave-shaped partition plate (16-2) between the horizontal plates, as shown in FIG.

In the figure, (20) indicates the motor of the suction fan (12).

Further, an ozone flow path case (14) communicating with the fan flow path case (13) includes an ozone generation section (15) and a catalyst (I).
6) can be freely replaced with a cassette type.

The gist of the present invention resides in that, in a toilet bowl equipped with such an ozone deodorizing device, the flow path particularly near the ozone generating part (15) is made into a deformed state.

Such deformed states include, for example, the bent state shown in FIG. 6, the spiral state shown in FIG. 7, and the channel deformed state due to repeated diameter reduction and diameter expansion shown in FIG. 8.

By setting it in such a deformed state, the ozone generating part (15
) The ozone generated in ) is easily mixed with odor, and the residence time of ozone and odor can be set appropriately.
In addition, the odor pushed out by the suction fan (12) is strong and does not come into contact with ozone, thereby favorably promoting decomposition and deodorization of odor components.

Here, to specifically explain each deformation state, the one shown in FIG. 6 shows a bent flow path (X), and the ozone flow path case (1
4) The flow path inside the case (X-1) is bent left and right, and when the air sent from the suction fan (12) comes into contact with ozone, the bent case (X-1) causes the air to flow in a zigzag pattern instead of in a straight line. Because of the flow, the contact residence time with ozone becomes longer, and furthermore, odor can be applied completely to the ozone generation area from the ozone generation part (15). On the lower side, the ozone flows in a zigzag pattern, creating a turbulent flow, and the odor is well mixed with the ozone, thereby promoting the odor decomposition effect of ozone.

In addition, in the above explanation, the case where the bent flow path (X) is arranged before and after the ozone generating part (15) has been explained, but it may be arranged only on the upper side or the lower side of the ozone generating part (15). It is also possible if the ozone generating part (
It is also possible to limit the bending state only to the location (15) and only to the location of the generating portion (15). Note that (X
-2) shows a partition plate protruding into the ozone flow path case (14) to form the bent flow path (X).

Next, the flow path deformed into a spiral state shown in FIG. 7 will be explained. In this example, the ozone flow path case (I4)
Since the area near the ozone generating part (15) in the inside is bent into a spiral shape, the odor and ozone are reversed and mixed well when passing through this spiral flow path (Y). This can promote the odor decomposition effect of ozone.

When such a spiral flow path (Y) is provided on the upper side of the ozone generation section (15), when the odor passes through this spiral flow path (Y), it is rotated and the odor is transferred to the ozone generation section (15). When reaching the point, the ozone rotates instead of in a straight line and comes into contact with the ozone, allowing the entire ozone generation area to be touched, further promoting the decomposition function.

In addition, when such a spiral flow path (Y) is provided on the downstream side of the ozone generation section (15), air mixed with -tan ozone and odor flows into the spiral flow path (Y) in the same generation section. It enters, receives rotational action, and is mixed and agitated.
This increases contact with ozone and improves the promotion of oxidative decomposition. Note that (Y-1) indicates a spiral case.

Note that (Y-2) indicates a spiral plate formed in the channel so as to have a spiral shape.

Next, a case will be described in which the flow path is deformed by repeating diameter reduction and diameter expansion as shown in FIG. 8.

In this embodiment, a diameter-reducing/diameter-expanding flow path (Z) is formed before and after the ozone generating part (15), and by repeating this process, the same functional effect as the repeated use of an orifice can be obtained. , Ozone and odors diffuse from the diameter-reduced portion to the diameter-expanded portion, which promotes the mixing action during diffusion, and this diffusion function is repeated over and over again due to repeated diameter contraction and expansion. When mixed, the mixing and stirring function further increases.

In addition, the diameter-reducing/diameter-expanding flow path (Z) is connected to the ozone generating part (15).
If it is installed only on the upper side of the ozone generator, the diffusion of odor will be amplified at the point where it reaches the ozone generator (15), and the ozone generator will be able to come in contact with the ozone generator evenly. If the enlarged diameter flow path (Z) is provided only on the downstream side of the ozone generating part (15), ozone and odor will diffuse from the reduced diameter part to the enlarged diameter part by the orifice effect, and this repetition will further increase the mixing effect. This increases the decomposition effect of ozone.

Note that (zi) indicates an uneven inner wall for forming diameter reduction and diameter expansion in the flow path.

In addition, the ozone deodorization device (M) has a functional part casing (1
), but can also be provided at other locations, such as the side or front of the toilet bowl body (A).

Furthermore, the ozone deodorizing device (M) according to the present invention may include, as appropriate,
It can also be applied to living spaces other than the above-mentioned toilets, such as kitchens, washrooms, bathrooms, living rooms, etc.
