The filter cleaning kit 110 may move the left and right ends of the filter frame 90 at least once in a reciprocating direction while driving the moving motor 121 to separate foreign substances from the filter 80 from the filter 80.

When the filter cleaning kit 110 moves as described above, the light emitting device 140, which is an electric component installed in the filter cleaning kit 110, moves together with the filter cleaning kit 110 to move the light transmitting part 45 of the front panel 40. The light is irradiated through, and the user can confirm that the light transmitting part 45 is currently being cleaned.

Meanwhile, when the filter cleaning kit 110 moves as described above, the lead wire 143 connected to the light emitting device 140 may have a space S between the wire guide 200, that is, the rear cover 152 and the front cover 154. And moves along the light emitting device 140 while being protected by the rear cover 152 and the front cover 154. That is, the lead wire 143 is covered with the rear cover 152 and the front cover 154 without interfering with the heat exchanger 60, the front frame 20, or the like, and the light emitting device 140 and the controller 70. Send and receive signals between

When the filter cleaning kit 110 as described above is positioned on the upper side of the separator 162 while being reciprocated left and right, the control unit 70 drives the cleaning motor 182 of the cleaning suction force generator 170.

The filter cleaning kit 110 is in contact with the separator 162 so that foreign matter is separated by the separator 162, and the foreign matter separated from the filter cleaning kit 110 is separated from the space 98 and the suction duct 170. It is sucked into the suction duct 170 together with the air sucked into.

Air and foreign matter sucked into the suction duct 170 pass through the connection hose 184 and the cleaning suction force generator 180, and flow into the dust collecting container 190, and the foreign matter flows into the dust collecting container 190. Separated from and is contained in the dust collector 190, the air is discharged to the outside of the dust collector (190).

On the other hand, the present invention is not limited to the above embodiment, the movement motor 121 is mounted on the filter cleaning kit 110 itself, the rack is formed long in the left and right directions on the lower portion of the filter frame 90, The pinion is coupled to the rack to the motor 121 and is moved while being rotated along the rack, and the pinion and the moving motor 121 and the filter are moved by moving the pinion while moving the motor 121 to the left and right along the rack. The cleaning kit may be moved left and right together, and the lead wire (not shown) connecting the moving motor 121 and the control unit 70 may be guided / protected by the wire guide 200 installed in the filter frame 90. Of course, various implementations are possible within the technical scope to which the present invention belongs.
