That is, the lead wire 143 is covered by the rear cover 152 and the front cover 154 and does not interfere with the heat exchanger 60 or the front frame 20, and the light emitting device 140 and the control box 70 Transmit and receive signals between ).

When the filter cleaning kit 110 is positioned above the separator 162 while reciprocating left and right as described above, the control box 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 the space part 98 and the suction duct 170 in the vicinity thereof. It is sucked into the suction duct 170 together with the air sucked into.

Air and foreign substances sucked through the suction duct 170 pass through the connecting hose 184 and the cleaning suction power generator 180, and flow into the dust collecting container 190, and the foreign substances are air from the inside of the dust collecting container 190. It is separated from and contained in the dust collecting container 190, and air is discharged to the outside of the dust collecting container 190.

On the other hand, the present invention is not limited to the above embodiments, and the moving motor 121 is mounted on the filter cleaning kit 110 itself, and a rack is formed in the left and right direction under the filter frame 90, and for movement The pinion, which is engaged with the rack and rotated along the rack, is connected to the motor 121, and the pinion and the moving motor 121 and the filter are moved left and right along the rack while the pinion is rotated when the moving motor 121 is driven. It is also possible to move the cleaning kit left and right, and a lead wire (not shown) connecting the moving motor 121 and the control box 70 is guided/protected by the wire guide 200 installed on the filter frame 90. It is also possible, and of course, various implementations are possible within the technical scope to which this invention belongs.
