Description

Air purifier equipped with automatic air filter cleaning device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air filter provided with an automatic cleaning device, and more particularly, to an air filter provided with an air filter automatic cleaning device capable of automatically cleaning an air filter provided in a relatively large- Air purifier.

Air purifiers usually have a consumable filter inside, regardless of their capacity, so if the filter is used for a certain period of time, the filter becomes clogged due to foreign matter or is susceptible to bacterial propagation. In particular, in the case of medium and large air cleaners installed in public facilities, large buildings, and various industrial sites, the burden of the cost for cleaning the filter is increased in proportion to the importance of the filter management. Therefore, efforts have been made to simplify the filter cleaning operation and shorten the time required.

In connection with this, there have been proposed the following Korean Public Utility Model Publication No. 1997-0057088 (Prior Art 1), Korean Registered Utility Model No. 0392908 (Prior Art 2), Korean Registered Utility Model No. 0326102 (Prior Art 3) Can be referenced.

The prior art document 1 has an air supply pipe moving device provided with an air supply pipe provided with nozzles at the tip thereof and connected to a screw shaft at the bottom of the air supply and air moving device so as to move the air supply pipe And the apparatus is moved forward and backward.

In the prior art document 2, a vertical groove is formed in the casing to form a primary filter layer, and a buoyancy tube having a cleaning rake fitted to the vertical groove is mounted on the outside of the casing. As the buoyancy tube moves up and down according to the water level in the septic tank, And cleaning the car filter layer is proposed.

According to the prior art document 3, a plurality of rotation injection nozzle tubes are provided at regular intervals on the surface facing the distribution pipe and the air filter, and the pollutants collected on the surface of the air filter while rotating by the magnetic force by the injection pressure of the fluid are injected Cleaning by a fluid which is a cleaning fluid.

However, in the case of the above-mentioned prior art documents, it is difficult to apply to the air cleaner of medium and large capacity or to apply to the air filter cleaning of the cylindrical structure. Furthermore, since the air filter is difficult to clean while the air cleaner is operating, the maintenance cost is reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-described problems in the prior art, and it is an object of the present invention to provide an air cleaner having a relatively large structure with a large number of air filters, And to provide an air cleaner equipped with an automatic air cleaner which is easy to maintain and maintain.
