Description

Air purifier

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier for collecting pollutants such as dust in indoor air into water and releasing a part of water to the outside to act as a humidifier. The present invention relates to an air purifier for continuously collecting contaminants such as dust as the stored water circulates, and humidifying indoor air by drawing moisture out of the water to a certain extent.

The cleanliness of the indoor air has a great influence on the health as the life time of modern people is mainly increased in indoor activities.

However, recent indoor air pollution is much more polluted than outside air pollution and is at a serious level. Such indoor air pollution is caused by inflow of outside air, for example, contained in polluted dust or exhaust gas of vehicles (HOC's), volatile organic compounds (VOC's), or sick house syndrome (VOCs) that come from the living environment, as well as contamination by microorganisms such as fungi, mites, bacteria, (sick house syndrome), which is the main cause of pollution such as aldehydes and asthma and atopic dermatitis to elderly people and children, as well as indoor air pollution caused by ozone and other diseases.

Thus, the conventional air purification method is a filter method, which means that if the air containing dust is attracted unless the filter is frequently replaced, the dust accumulates on the surface of the filter cloth, and the efficiency of collection is drastically reduced due to the filter clogging, Therefore, there is a problem of maintenance due to regular replacement, and secondary environmental pollutants are generated due to the waste filter nonwoven fabric, which is a major cause of global environmental pollution.

In addition, it is necessary to provide a separate humidifier because it does not become a humidifier, and silver particles, photocatalyst, ultraviolet ray method, etc. are promoted. However, the air purification process including photocatalyst, electrostatic precipitator, The air cleaning efficiency of the apparatus is low.

As another air purifier, an anion generating air purifying device has been developed, and it is known that there is a side effect of generating ozone which is harmful to human health hygiene. A dry type centrifugal air purifier has a theoretically 90% -95% It is impossible to purify fine particulate dust, pollen, cigarette smoke, and noxious gas, which has an efficiency but is harmful to human health and hygiene of 5 μm or less. It is a level of simply removing particulate matter in the air by limited centrifugation.

As a wet air purifier, there has been developed a method of purifying air by the viscous adhesive force of water by two-dimensional surface contact of water by attracting the air flow. This is because only pollutants in the air coming into contact with the surface of the water film are viscous And most of the pollutants which do not come into contact with the surface area of the water film are not cleaned.
