Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toiletry deodorizing environment purifier which is installed in a toiletry room provided with a toilet bowl to deodorize the toiletry room.

[0002]

2. Description of the Related Art Conventionally, various methods have been used for toiletry deodorization. For example, it is known that masking is performed with an aromatic agent or the like for deodorization, or that a fan or the like is used to forcibly discharge odors outside a toiletry room. However, none of these have reached a fundamental solution to the malodorous component. Therefore, recently, a device for chemically deodorizing ozone is often used, and a toilet equipped with this ozone deodorizing device is often installed in a toilet. The ozone deodorizing device decomposes odorous components by ozone to make them odorless and discharges them into the toiletry room.

[0003]

However, an apparatus for deodorizing with ozone has a deodorizing effect, but acid gases such as SO ₂ and NO ₂ are generated by a chemical reaction as a by-product of the reaction between ozone and odorous components. However, since this acidic gas is released into the toiletry room as new air pollution, there is a problem that the vicious circle cannot be completely cut off.

Therefore, an object of the present invention is to provide a toiletry deodorizing environment purifier which removes not only the deodorization by ozone but also the acid gas generated by the ozone deodorization reaction.

[0005]

In order to achieve the above-mentioned object, the toiletry deodorizing environment purifier of the present invention is provided with a main body case having an intake port for inhaling ambient air and discharging the inhaled air. And an air flow passage that connects the air intake port and the air exhaust port to each other, and a fan that guides ambient air from the air intake port to the air exhaust port through the air flow passage. The ozone decomposition catalyst portion and the acid gas adsorption portion are arranged in this order from the upstream side to the downstream side of the air flow passage.

[0006]

In this toiletry deodorizing environment purifier, the air containing the odorous component sucked from the intake port by the operation of the fan first reaches the ozone generating section, and the gas phase ozone and the odorous component generated in the ozone generating section are separated. After mixing, this mixture is sent to the ozone decomposition catalyst section. In the ozone decomposition catalyst section, the oxidation reaction between ozone and odorous components is promoted, and the odorous components are completely decomposed. However, at this time, acid gases such as SO ₂ and NO ₂ are generated by the reaction between ozone and odorous components. The generated acidic gas is completely adsorbed and removed when passing through the next acidic gas adsorption section, and becomes purified air. Then, the purified air is discharged from the exhaust port to the outside of the deodorizing environment purifier by the fan.

As a result, in addition to deodorization with ozone, acid gas is also removed, so that the odor and the secondary pollution source can be completely removed. The purifier of the present invention is
Not only Japanese-style toilets with Western-style or Japanese-style toilets installed, but also Western-style toiletries with baths and other Western-style toilets installed in all rooms where toilets are installed, and deodorizing and purifying those rooms. Is to do.

Are provided on the circuit board 31. The purifier 1 configured as described above is installed in a toiletry room, and its installation examples are shown in FIGS.
Shown in 1. FIG. 6 is an example in which the purifier 50 is attached to an ordinary Western-style toilet 60 by an appropriate attachment 52. In this case, the human body can be detected by the detection sensor 51 before mounting. The fixture 52 is not particularly limited as long as the purifier 50 can be fixed to the toilet seat of the toilet 60, and may have a structure that is hooked on the edge of the toilet 60, for example.

FIG. 7 shows a case of application to a Western style toilet 61 having a deodorizing air inlet, in which case an appropriate flexible duct 53 is used and one end of this duct 53 is connected to the deodorizing air inlet of the toilet 61. Then, the other end is connected to the intake port for toilet inside the purifier 50 (see reference numeral 3 in FIG. 1). Purifier 5
For example, 0 is provided on the wall surface within the range where the detection sensor 51 can detect a human body.

FIG. 8 shows a Japanese style toilet 6 having a deodorizing air inlet.
This is the case where the purifier 50 is installed in 2. Also in this case, as in FIG. 7, one end of the flexible duct 53 is connected to the toilet bowl 62.
The other end is connected to the deodorizing intake port of No. 2 and the toilet intake port of the purifier 50. FIG. 9 shows an example of installation in a toilet provided with a drawing toilet 63. Generally, in a toilet bowl, the inside of the toilet bowl is under negative pressure, so there is no odor increase from the inside of the toilet bowl, but biological odor is generated. The purifier 50 is fixed to the wall surface of the toilet within the detectable range. Further, in this example, the adapter 70 having a large number of through holes 70a as shown in FIG.
For example, an artificial flower 7

Further, the example shown in FIG. 11 is a toilet bowl 6 for men's small water.
4, the flexible duct 53 connected to the toilet in-air intake port of the purifier 50 is attached to the upper part of the toilet bowl 64 and sucks the odor rising from the toilet bowl 64. Next, the operation of the variously installed purifiers will be described. First, the flow of odor is shown in Figure 1.
2 and an arrow in FIG. The odor sucked through the inlet 3 for the inside of the toilet and the inlet 4 for the outside of the toilet flows to the portion where the ozone generator 7 is present, and is mixed with the vapor phase ozone generated from the ozone generator 7, and then the ozone deodorizing catalyst 8 Pass through. The ozone deodorizing catalyst 8 promotes the odor oxidation reaction, and when it passes through the deodorizing catalyst 8, the odorous components in the air are completely decomposed, but SO ₂ generated by the chemical reaction between ozone and the odorous components is Acid gases such as NO ₂ and NO ₂ are present. However, all of the acidic gas is adsorbed and removed when it passes through the next acidic gas adsorbent 9, and the air that has passed through the adsorbent 9 is completely purified, and this purified air is sucked by the fan 6, It is discharged from the exhaust port 5 to the outside of the purifier 1.

By the way, in the toiletry room,
It is preferable to regularly deodorize the air in the toiletry room not only when the toilet is being used but also when the toilet is not used. In this case, it is desirable to effectively carry out the timing of operation and stop of the purifier 1, and this point will be described next. The purifier 1 of this embodiment has an inlet 3 for the inside of the toilet and an inlet 4 for the outside of the toilet, but here, for about 6 minutes after the user sits on the toilet seat, the odor from the inlet 3 for the inside of the toilet only. Suction the outside of the toilet 4
Has been set so that no odor is sucked. When the user approaches the purifier 1 within about 1 m, the detection sensor 30 detects the human body and starts at the same time.
For 6 minutes after sitting down, the solenoid 20
Is operated, the damper 23 causes the intake port 4 to
Will be closed. The reason why 6 minutes has passed since the person is seated is that the stool usually takes 6 minutes.

After 6 minutes, even if the user is still sitting, the solenoid 20 is stopped to separate the damper 23 from the intake port 4 and open the intake port 4. As a result, the odor inside the toiletry room is sucked through the intake port 4 in parallel with the suction of the odor from the intake port 3, and the residual odor floating in the room is deodorized. Then, for at least 12 minutes after the user leaves the toilet seat, the suction of odors through the intake ports 3 and 4 is continued,
Deodorization in the toilet bowl and room continues. However, when the sitting time is 6 minutes or more, it is preferable to continue deodorizing the toilet bowl and the room for about 24 minutes. Even when not using the toilet
For example, every 48 minutes, for 12 minutes (that is, once a hour), deodorization in the toilet bowl and the room is periodically repeated to prevent odor from staying in the toiletry room. It should be noted that it is desirable to set the operation of the purifier 1 to be stopped for safety when seated for 30 minutes or more.

The embodiment described above is merely an example, and various modifications can be made. For example, the size of the entire purifier is determined according to the size of the toilet room to be installed, and the ozone generator, ozone decomposition catalyst, acid gas adsorber, fan, etc. to be placed in the main body case are also arranged. You just have to change the way. Also, turn on the purifier shown above.
The timing of turning off / off is merely an example, and may be changed as appropriate.
