DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet air cleaner.

[0002]

2. Description of the Related Art Indoor air contains many harmful particles, such as house dust containing dust and dead mites, pollen, mold spores, bacteria, and tobacco smoke.

[0003] These house dusts cause atopic dermatitis and asthma, and tobacco smoke causes lung cancer.

[0004] Due to these health concerns, the demand for air purifiers has recently increased.

[0005] On the other hand, with the spread of electric appliances and OA equipment in the room, negative ions have been extremely reduced due to electromagnetic waves, heat, static electricity and the like generated from them.

[0006] The decrease of the negative ions is extremely negative in order to spend comfortably indoors and refresh the body and mind. That is, it is considered that a person can feel refreshed due to the function of the negative ions contained in the air. Therefore, when the negative ions decrease, the person cannot spend refreshingly.

It has also been found that negative ions are caused in nature by the phenomenon that, when water splits in air, large particles are positively charged and small particles are negatively charged. This is because when the energy of collision or vibration is applied to a water droplet, the surface of the water droplet becomes a negative outer electric layer and a positive electric double layer inward, and when the water droplet breaks up, the negative external electric power follows small particles that break off from the surface and fly out. The inner positive electricity is due to the remaining large particles. As a result, a large amount of negative ions are generated near the waterfall where the water drops splatter violently and in the air after the rain, and when you inhale these, you will feel refreshed.

Therefore, various air purifiers have been sold in the past. There are two types of such conventional air purifiers. One is a fan type where air is circulated by a fan and adsorbed by a filter.
The other is an ion type that collects dust using the power of ions.

[0009]

However, both the fan type and the ion type have a certain effect on dust removal, but they have only such an effect. However, indoor air contains unpleasant odors from cigarettes, pets and toilets, and also contains bacteria. In addition, moderate moisture is required to spend comfortably. The conventional one cannot expect these effects at all. And, of course, the fan type cannot increase the amount of negative ions in the air.

[0010] In addition, since the ion type is a type in which negative ions are electrically generated by corona discharge generated by a negative discharge line, ozone and NOx are generated as by-products. There is no problem if they are trace amounts, but if they do not have a function to control the amount of generation, they may exceed the environmental standard values. At the same time, since electromagnetic waves are generated at the same time, there is a concern not only of reducing the number of negative ions but also of affecting the human body. Furthermore,
Electrically generated negative ions are simple substances that do not bond with water molecules, so they have a large amount of activity, are quickly neutralized, and cannot float in the air for a long time.

From these facts, the conventional air purifier has a low penetration rate. Therefore, as a result of intense research, the present inventor has strongly applied water to the inner wall of the septic tank to split it into ultra-fine particles, and the fan sucked air through the innumerable floating of fine particles and passed through By doing so, in addition to dust removal, deodorizing, humidifying effects, and antistatic effects can be obtained, and negative ions are included in the air in large quantities without having a negative surface as seen in the ion type. The inventors have found that the present invention can be performed, and have completed the present invention.

[0012]

SUMMARY OF THE INVENTION Accordingly, the gist of the present invention is to provide a septic tank having an air inlet and an air outlet, a suction fan mounted on the air inlet, and containing a required amount of water. And an appropriate means for strongly applying the water to the inner wall surface of the septic tank to split it into ultrafine particles.

Further, a means for strongly dividing water into the ultrafine particles by strongly hitting the inner wall surface of the septic tank, for example, connecting a water jet nozzle having a large number of small holes to the water jet nozzle and the bottom of the septic tank. You may make it comprise with a pipe and the pump provided in the middle part of this pipe.

Further, acidic water or acidic electrolyzed water generated by electrolysis may be used as the water. The use of such water can provide a bactericidal effect. Also, since the bacteria do not grow in the water, no odor is generated. Therefore, repetition of long-time circulation can be used. Furthermore, since an acid is contained in the air, an antibacterial action can be expected.
In addition, in the case of the acidic electrolyzed water generated by electrolysis, since it is made acidic without using a chemical, there is no risk of harm to the human body and the cost of the chemical can be saved.

Further, a water electrolysis device may be connected to the septic tank, and the acidic electrolyzed water generated by the electrolysis device may be used. In this case, the water can be directly supplied from the electrolysis device into the septic tank when the water is changed.

Further, the inner wall surface of the septic tank may be roughened. In this case, the direction in which water rebounds and scatters becomes irregular, and the contact ratio of ultrafine particles to harmful particles such as dust can be increased.

Next, the operation of the above embodiment will be described. The pump 13 is operated to pump the acidic electrolyzed water 6 to the water injection nozzle 11 at a predetermined flow rate. Thereby, the water jetted from the water jet nozzle 11 vigorously hits the inner wall surface of the septic tank 1. When they bounce off, they split into ultrafine particles.

Then, when the air is sucked by the intake fan 4 while the countless ultra-fine water particles are floating,
Dust, odor particles, bacteria and the like in the air come into contact with the water particles and fall to the bottom of the septic tank 1.

Further, since negative ions are generated when water hits and rebounds and splits into ultrafine particles, a large amount of negative ions can be contained in the air. Furthermore, the generated negative ions are combined with ultra-fine water particles, so that the stability is increased, and the negative ions float in the air for a long time without being neutralized by the positive ions.

Further, since ultra-fine water particles are contained in the air, appropriate humidity can be given to the room. Also,
Positive ions and static electricity from indoor appliances and OA equipment can also be neutralized by negative ions and ultra-fine water particles.

[0027]

Since the present invention has the above-described configuration and operation, it is possible to obtain not only dust removal but also deodorization, humidification, and antistatic effects based on a completely different principle from the conventional air purifier. You can do it.

Further, a large amount of negative ions for refreshing the mind and body can be contained in the air.
Also, the generation of negative ions is not electrical, but is based on the same principle as in the natural world, so that it has a long floating time in the air and can be expected to be effective.

When acid water or acid electrolyzed water generated by electrolysis is used as the water, a sterilizing effect can be obtained. Also, since the bacteria do not grow in the water, no odor is generated. Therefore, repetition of long-time circulation can be used. Furthermore, since an acid is contained in the air, an antibacterial action can be expected. Also, in the case of acidic electrolyzed water generated by electrolysis, since it is made acidic without using chemicals, there is no risk of harm to the human body,
And also the cost of medicine can be saved.
