The elastic force of the biasing force spring 468 is greater than that of the return spring 470. Accordingly, when the distal link 440 is pulled in the upward direction (left in FIG. 12), the return spring 470 increases, and the biasing force spring 468 is rotated by pulling the rotation lever 460 as it is.

As an operation for raising the second layer filter 120 mounted on the tray 450, when the lifting operation lever 410 is rotated in the upward direction (clockwise in FIG. 11), the first link 420 and the second link The distal link 440 connected by 430 is pulled in the upward direction (left in FIG. 12).

As the distal link 440 is pulled in the upward direction (left in FIG. 12), the return spring 470 is increased, and the bottom surface of the second layer filter 120 is pushed by rotating the rotation lever 460 in the upward direction. Raise.

For replacement of the second layer filter 120, when the lifting operation lever 410 is rotated in a downward direction (counterclockwise in FIG. 11), the second link 430 moves the end link 440 in the downward direction (FIG. 12 to the right), and the rotation lever 460 rotates in the downward direction and descends, so that the second layer filter 120 is placed on the tray 450. The second layer filter 120 placed on the tray 450 is pulled out and replaced with a new one.

In this way, the second layer filter 120 can be easily lifted by the filter lifting mechanism 400 to be in close contact with the cabinet frame 130 to be sealed, thereby simplifying the installation and replacement process.

In the above, specific preferred embodiments of the present invention have been illustrated and described. However, the present invention is not limited to the above-described embodiments, and any person having ordinary knowledge in the technical field to which the present invention pertains without departing from the gist of the present invention claimed in the claims may implement various modifications.
