Description

Clean air generator

The present invention relates to a clean air generator, and more specifically, first filtering in which fine dust particles are filtered out by introducing outdoor air into the room, and then by an air stone immersed in the water of a water tank. Secondary filtering is performed so that ultra-fine dust and heavy metals are precipitated in the process of contacting and passing the generated micro-bubbles with water, and then supplying clean air including oxygen outdoors with natural humidification without changing the temperature inside the room. It relates to a clean air generator.

Traditionally, air purifiers have only the function of purifying air using a predetermined filter or a filtering method using electricity. And, regardless of the air cleaning function, the humidifier is supplied by generating water vapor through various methods such as generation of water vapor using ultrasonic waves, generation of water vapor using heating, or generation of water vapor using a method of mixing them, or natural vaporization. By doing this, it can be said that the humidification of indoor air is performed.

And recently, a product having a humidification function and an air cleaning function as described above are being released in various forms, and a so-called'airwasher' or a'wet type air purifier' may be mentioned. Air purifiers having a humidifying function in this way, Patent No. 10-0863307, Patent No. 10-0805667, Patent Publication No. 10-2010-0084828, Utility Registration No. 20-0157935, Utility Registration No. 20-0278594 It has been proposed in various forms in et al.

Looking at the configuration of Registered Utility Model No. 20-0278594 disclosed as a prior art of air purifier, one of the air conditioners that can use the air cleaning function and humidification function at the same time, a filter that filters air and a suction that inhales air A fan and an inlet pipe that is submerged in the water tank and connected from the outside of the water tank at a predetermined position on the body, and the air is supplied through the inlet pipe and is connected to the inlet pipe to generate micro bubbles in the water tank and discharge through the discharge pipe. It is made into.

This air purifier is a water filter-type air purification method that uses water as a filter. After inhaling air containing dust, bacteria, viruses, fungi, mites, pollen, heavy metals, etc. In the process of contacting and passing through the water in the tank, foreign substances or impurities are removed, and then clean air is supplied to the room through the discharge port.

A filter for filtering air in a conventional air purifier including the prior art as described above includes a filter made of non-woven fabric, cloth, paper, etc. to filter out dust larger than the pores in the process of passing the air. In the case of contained odors, an activated carbon filter that is adsorbed using activated carbon is included.In order to introduce outdoor air using such a filter, it is installed at the entrance to the upper wall of a building to perform filtering function, and then outdoor air Can be introduced into the room by an air blower (suction fan), but it is difficult to apply it because it has the following disadvantages.

In other words, in order to filter outdoor air, when a filter made of a filtration filter and an activated carbon filter is installed to be exposed to the outside at a high position above a building, etc., and then the air blower (suction fan) inhales, the outdoor air As the installation period gradually increases, such as the filter for filtering the filter is easily clogged by foreign substances, the filter function and suction power are greatly reduced, and the filter cleaning is not easy.

In addition, in a conventional air purifier, the air stone is installed so that it is submerged in the water tank, so that microbubbles are generated by the air stone's many pores, so that foreign substances or impurities contained in the incoming air contact and pass through the water of the water tank. Although these airstones can be removed by one means, since these airstones are fixedly installed in the water tank, the direction of waves generated as the microbubbles spread out in the water tank is always constant and the dynamics are greatly reduced, so there is a concern that water pollution may occur quickly. Therefore, in order to reduce scale or water pollution in the tank and maintain the cleanliness of the water, there was a hassle of replacing the water in the tank from time to time.
