BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner, and more particularly, to an air cleaner which is improved in air circulation and is provided with a sealing function to completely block the flow of air inside and outside, and is applicable to various sizes.

The air purifier removes the dust and contaminants contained in the air by allowing the outside air to pass through the filter. By using a fan (motor) so that the outside air can be discharged through the filter, The air is filtered through the evacuation process.

The air cleaner is divided into a filter type and an electric dust collecting type. The filter type filters dust and contaminants in the air by a filter. The electric dust collecting type uses the principle that dust or contaminants in the air are adsorbed and removed by a dust collector by an electric field.

A typical air cleaner includes an upper case, a housing and a lower case, and a filter unit inserted into the housing to filter air.

The air purifier also has a packing for sealing between the housing and the filter unit.

Since the air cleaner is in close contact with the inner surface of the housing only due to the self-stretchability of the packing, the air tightness of the air cleaner is deteriorated, and wear is generated in the process of disassembling and assembling the filter unit.

In order to solve such a problem, Korean Patent Registration No. 10-1537567 discloses a filter unit sealing device for an air purifier.

Korean Patent No. 10-1537567 discloses a filter unit sealing apparatus for an air purifier, which comprises a packing unit coupled to an upper end of a filter unit and closely attached to an inner surface of a housing, A packing tightening portion provided in the housing to closely contact the packing portion with the housing side; And a packing unit provided between the packing unit and the filter unit so that the packing unit can be coupled to the filter unit, wherein the packing unit includes a pressure-tightening unit that is brought into close contact with the housing through the contact of the packing unit; And a sealing tight portion extending from a lower end of the lid member of the housing so as to be in close contact with the inner surface of the housing main body and having a pressing rib bended at a lower end thereof so as to be in contact with the upper surface of the pressure tight contact portion .

However, although the sealing function may be improved as a sealing device for the filter unit, since the shape of the packing part is very complicated, and additional constructions such as a pressure tight contact part and an auxiliary sealing part are added for sealing the packing part, It has a disadvantage in that it has to be done.
