The filter support portion 122 provides ease of pressurization through both side handles 122a and is fixed to the filter support portion 122 by allowing the latch 123 to be fixed in the valley s of the elastic fixing plate 128. In this case, the contact area with the second filter 6 can be improved due to the planar structure.

In addition, the filter support 122 may be a semi-permanent fixation / support means since the position may be changed by left / right sliding. When the filter is replaced or repaired after installation, the filter support 122 may slide left or right to have one side pull. After changing the position again to the center, it enables easy work processing. At this time, even if the position change of the filter support 122 occurs, the elastic fixing plate 128 supports both sides by walking the latch hanger 123 through the left / right valleys (s) can provide a stable fixing force to the filter support continuously. Will be.

Meanwhile, referring to another embodiment of the second filter support means 120 installed on the air supply side, the frame fixing part 124 is mounted and inserted into the lower side from the upper side of the fixing frame 40 to fix the frame ( 40 and then the filter support 125 connected by the connecting member 127 is inserted into the latch 126 coupled to the upper side of the fixing unit 124 to fill the latches, and then the lower surface of the filter support 125. The upper surface of the second filter 6 is supported by surface contact.

Here, the frame fixing part 124 and the filter support part 125 also have the same function as the case of the above-described embodiment in the fixing force and the support force will be omitted, and the handle formed on one side of the filter support (125) ( 125a facilitates the exertion of tension for the latch and sliding movement together with the ease of mounting.

The latch hook 126 is to be fixed in the fixing groove 124c formed on the upper side of the fixing portion 124 to achieve a stable fixing.

The connection member 127 is to enable a quick and efficient operation by preventing the actual separation of the fixing portion 124 and the support 125.

As described above, the first filter support means 110 and the second filter support means 120 do not undergo various processes during assembly and disassembly according to the assembly, replacement, and repair work of the filter. This is useful for speeding up the process. That is, assembly and disassembly work is possible with one touch.

In addition, there is no inconvenience to be installed in a fixed position because there is no need for a separate fixed means formed in a fixed position unlike the existing, and the labor cost can be minimized by pushing or pulling in the desired position by the operator In addition to the savings, there is also an economic effect to reduce the maintenance cost of the air conditioning equipment.
