Description

Clean equipment wet process interior air

The present invention purifies the indoor air while the indoor air sucked by the blower passes through the wet filter and supplies it back to the room, and at the same time, vaporizes the moisture of the wet filter and supplies it to the room, as well as always keeping the indoor air clean. It relates to a wet indoor air cleaning device to maintain a proper humidity to create a comfortable indoor environment.

In general, an air cleaner is a device that purifies polluted air and converts it into fresh air. The air cleaner is used to create a pleasant indoor environment. A conventional air cleaner is a filtering method using a predetermined filter. Was clarified.

The air cleaner has a remarkable difference in air purification ability according to the performance of a filter for purifying contaminated air, and furthermore, there is a problem that can increase the pollution of indoor air rather than replacing the filter in a timely manner.

On the other hand, recently, a wet air cleaner, not a filter method, has been released in various forms. An example is a so-called 'airwasher' or 'wet air purifier'.

Conventional wet air cleaners are mostly equipped with a scrubber system that sprays water by spray nozzles to remove dust and gas from the air. This method is designed to inhale air into the inside of the air purifier and to spray water using a spray nozzle inside the air purifier and to remove it by colliding with dust or gas in the air. It is composed of water storage tank, water supply valve, wastewater valve, circulation pump, blower fan, controller and collision plate.

Another method is to remove the dust introduced by the fan in a collision method while the disk-shaped plate is rotated in the water to the appropriate depth.

Since the wet air cleaner is installed indoors and can supply insufficient moisture by evaporation or spraying, it is known that the indoor air purification as well as humidity control are possible.

However, the spraying method may increase the size of the product as well as the leakage problem, there is a problem that the air purification efficiency is not high because the contact area of water and air is small.

In the case of the disk method, it is difficult to expect a satisfactory purifying effect because the contact portion of the air is limited to a part of the surface area of the disk as the blower air contacts only part of the disk.

Therefore, the present inventor is provided with an indoor air management apparatus having a humidification function of the Korean Patent Publication No. 10-2014-0000629 as shown in Figure 1 invented to solve the above problems and looks at the configuration as follows.
