Abstract

PURPOSE:To enable the promotion of deodorizing effect by a catalyst by a method wherein a suction fan is arranged between an ozone generating section and the catalyst and ozone generated with the ozone generating section is stirred up intensely with the suction fan to be diffused and mixed into air containing malodor. CONSTITUTION:Upon sitting on a stool 2, a sitting sensor S1 sends a detection output to a control section D, with the driving of a suction fan F, a high voltage is generated with a high voltage generator 19 and applied to an ozonizer 17 to generate ozone in an ozone treating passage R. As a result, malodor generated in an internal space of a toilet body A is sucked in the ozone treating passage R, in which the odor is mixed with the ozone effectively to perform a deodorizing treatment. A catalyst S is arranged on the downstream side of the ozone treating passage R. The mixing of the malodor and the ozone is further promoted as passing through the catalyst S to promote the deodorizing processing. Thereafter, the exhaust deodorized completely is discharged into a toilet space through a discharge port 10.

On the other hand, the ozone deodorizing device Y shown in FIG. 7 includes an ozone generator 105. A catalyst 106 and an intake fan 107 are arranged.

(c) Problems to be Solved by the Invention However, the ozone deodorizing apparatuses X and Y still have the following problems to be solved.

That is, in the ozone deodorizing device X, the intake fan 101
Since the catalyst 103 is placed upstream of the ozonizer 102, the ozone generated from the ozonizer 102 cannot be sufficiently diffused and mixed into the odor-containing air.
However, the deodorizing effect could not be sufficiently increased.

In addition, in the ozone deodorizing device Y, since the intake fan 107 is arranged downstream of the catalyst 106, as in the ozone deodorizing device C, the ozone generated by the ozonizer 105 is sufficiently diffused and mixed into the air containing bad odors. Since the odor was supplied to the catalyst 106 without being able to do so, the deodorizing effect could not be sufficiently increased.

An object of the present invention is to provide an ozone deodorizing device that can solve the above problems.

(d) Means for solving the problem The present invention is configured such that an intake fan is disposed between the ozone generator and the catalyst, and the ozone and malodorous air are mixed sufficiently and then passed through the catalyst. The present invention relates to an ozone deodorizing device characterized by the following.

(E) Functions and Effects In the present invention, since an intake fan is placed between the ozone generation section and the catalyst, the ozone generated by the ozone generation section is strongly agitated by the intake fan, and the ozone is removed from the odor-containing air. can be diffused and mixed. Therefore, the deodorizing effect of the catalyst can be promoted.

In this way, the intake fan can be used not only for its original suction effect, but also for promoting the deodorizing effect by diffusing and mixing ozone into the foul-smelling air.

As shown in FIG. 4, a deodorizing duct 7 is disposed below the warm air duct 6, and the duct 7 has an inlet 9 at its tip connected to the ball part a of the toilet body A. It is open and extends from the inlet 9 along the middle part 1-3 of the casing to the center of the left sleeve part 1-1, and the terminal end is an ozone treatment flow path formed in the ozone deodorizing device M. It is connected to R.

As shown in FIG. 4, an exhaust port 10 is formed at the final end of the ozone treatment channel R of the ozone deodorizing device tM. It opens at the lower end of the hanging chamber case 11 formed at -3.

In this way, the flow path for deodorizing the bad odor generated in the toilet main body A is formed by the entire flow path from the inlet 9 of the deodorizing duct 7 to the exhaust port IO of the ozone treatment flow path R. , an ozone deodorizing device M is interposed between them.

In this embodiment, the ozone deodorizing device M is substantially built into the chamber case 11, except for the ozone generating section G.

Hereinafter, the configuration of the ozone deodorizing device M will be explained with reference to FIGS. 3 to 5.

As shown in FIGS. 3 and 4, the ozone generating section G, which constitutes a part of the ozone deodorizing device M, is arranged in the center of the rear part of the deodorizing duct 7. As shown in FIGS.

This is intended to promote ozone generation by the ozonizer 17.

As shown in FIG. 4, the ozone treatment channel R formed within the chamber case 11 is formed within a hollow goose song 20 extending in the vertical direction.

The upper part of the ozone treatment channel R communicates with the internal space of the deodorizing duct 7 through the communication port 21.

On the other hand, the ozone treatment flow path R forming the downstream side of the ozone generation section G
As shown in FIGS. 4 and 5, an intake fan F is rotatably disposed on the upper part of the engine.

In this embodiment, the intake fan F is formed of a sirocco fan in which a pair of front and rear discs 22, 23 are spaced apart and connected by a plurality of blade plates 24 arranged in the circumferential direction.

The boss portion 25 of the intake fan F is fixed to an output shaft 26 of a rotary motor disposed at the rear of the hollow casing 20.

This intake fan F sucks the malodorous air generated in the toilet main body A through the deodorizing duct 7 into the ozone treatment flow path R, and also converts the ozone generated in the ozone generator G into malodorous air, as will be described later. Can be mixed effectively.

Next, the catalyst S provided in the lower part of the ozone treatment flow path R formed in the hollow casing 20, that is, on the downstream side of the intake fan F, will be explained.

First, when you sit on the toilet seat 2 of the toilet with an ozone deodorizing device,
The seating sensor s1 installed at the rear of the toilet seat 2 sends a detection output to the control unit, and the drive output from the control unit drives the suction fan F and causes the high voltage generator 19 to generate high voltage, which causes the ozonizer to -17 to generate ozone in the ozone treatment channel R.

As a result, the bad odor generated in the internal space of the toilet main body A is sucked into the ozone treatment channel R, where it is effectively mixed with ozone and deodorized.

In addition, since the catalyst S is disposed on the downstream side of the ozone treatment flow path R, when the ozone passes through the catalyst S, the mixing of the odor and ozone is further promoted, and the deodorization treatment is further promoted. It turns out.

Thereafter, the completely deodorized exhaust gas is discharged into the toilet space from the exhaust port 10.

In particular, in this embodiment, since the intake fan F is disposed between the ozone generator G and the catalyst S, the ozone generated by the ozone generator G is strongly agitated by the intake fan F, and the ozone containing the odor is removed. Can be diffused and mixed in the air. Therefore, the deodorizing effect of the catalyst S can be promoted.

In this way, the intake fan F can be used not only for its original intake effect, but also for promoting the deodorizing effect by diffusing and mixing ozone into the foul-smelling air.
