Description

Multipurpose air cleaner

The present invention relates to an air purifier, and more particularly, to a multipurpose air purifier capable of purifying contaminated air in homes, industrial sites, and laboratory laboratories.

In general, air purifiers inhale contaminated air and filter out dust, odors, and contaminated particles contained in the air and purify the inhaled air into clean air. The air purified in this way is discharged to the outside of the air purifier.

To this end, the air purifier consists of a blower for discharging the purified air while introducing contaminated air, and a filter mounted to filter out dust, odors, and contaminated particles contained in the introduced air.

That is, the air purifier purifies the air introduced through at least one filter. At this time, if the filter is used for a long period of time, the filter is clogged by dust or contaminants adsorbed to the filter, and the filter loses its function. Therefore, after a certain period of time, the filter installed in the air purifier must be replaced.

For this reason, in recent years, the development of an air purifier in which filters can be easily replaced and filters having different functions are mounted is actively progressing.

For example, Korean Patent Registration No. 10-0500621 (announced on September 26, 2005) discloses an "air purification device". The conventional air purifier is characterized in that separate functional parts are designed in a modular manner, and in a state in which such modules are stacked, a pivoting lever provided on the outer side of the module clamps and supports the module from the outside.

The above-described conventional air purifying apparatus is a configuration in which a swiveling lever is fastened from the outside of the module. Contrary to the trend of air purifying apparatuses that are gradually becoming smaller in recent years, the overall width of the air purifying apparatus is increased, as well as a stacked filter. In order to replace the module, since the swivel lever must swing largely outside the module, it is difficult to replace the module due to interference with surrounding objects in a narrow space.

In addition, even if the length of the revolving lever is variable, there is a limitation in increasing the length, and thus the number of stacked modules is limited.
