As shown in FIG. 8, the self-winding device 200 includes a body 202 and a wheel 210 rotatably connected to the body 202 and having a lead wire 128 wound around its outer circumference.

The body 202 may be fixedly installed at one side position between the nozzle movement motor 121 and the controller 70, and the lead wire 128 is not fixedly installed between the nozzle movement motor 121 and the controller 70. It is also possible to move the position together, and will be described as being moved together with the nozzle movement motor 121 in a substantially intermediate position between the nozzle movement motor 121 and the control unit 70.

In addition, the automatic winding device 200 has a structure in which the motor connecting portion 128b and the controller connecting portion 128c are always in a tense state.

That is, the automatic winding device 200 includes a spring 220 for providing an elastic force to the wheel 210.

Here, the spring 220 is tensioned by the pulling force of the suction nozzle 110 when the suction nozzle 110 is moved from the standby position (A) toward the reverse position (B), the wheel 210 is the lead wire ( Allow the wheel 210 to wind around the lead wire 128 by a restoring force when the suction nozzle 110 is moved from the inverted position B toward the standby position A when the suction nozzle 110 is moved in the unwinding direction B. To rotate in the direction, the shaft fixing portion 212 is fixedly connected to the shaft 204 formed in the body 202, and the wheel fixing portion 214 is fixedly connected to the wheel 210 is formed.

Referring to the operation of the present invention configured as described above are as follows.

First, the main PCB 72 is a filter cleaning command is input through a control panel installed in the air conditioner or a remote controller for remote operation of the air conditioner, or the operating condition of the air conditioner is a filter cleaning condition, or periodically 74) to output the filter cleaning signal.

The cleaning PCB 74 outputs a control signal for driving the nozzle moving motor 121 when the filter cleaning signal is input, and outputs a control signal for driving the cleaning fan motor 181, and the nozzle moving motor 121 and the nozzle moving motor 121. The cleaning fan motor 181 is driven.

The nozzle movement motor 121 rotates the drive gear 122 when driven, and the driven gears 125 and 126 are moved along the fixed gear 124 while being rotated by the drive gear 123, and the suction nozzle 110. ) Moves along the filter 80 in a direction parallel to the longitudinal direction of the fixed gear 124.

Hereinafter, the forward / reverse driving of the nozzle moving motor 121, the left and right bidirectional movements of the suction nozzle 110, and the change in the length of the lead wire 128 will be described in detail.

The cleaning PCB 74 drives the nozzle moving motor 121 in the forward mode when the suction nozzle 110 is located on the right side of the filter frame 90 which is the standby position A shown in FIG. When 110 is located on the left side of the filter frame 90 which is the inverted position B shown in Fig. 7, the nozzle moving motor 121 is driven in the retracted mode.

In the forward mode of the nozzle movement motor 121, the rotation shaft 121b is rotated counterclockwise, which is one of a clockwise and counterclockwise direction, and the motor gear 121a is rotated counterclockwise together with the rotation shaft 121b. The drive gear 123 is rotated in the clockwise direction opposite to the motor gear 121a, and the driven gears 125 and 126 are rotated in the counterclockwise direction opposite to the drive gear 123, but are fixed gears. The suction nozzle 110 is slid to the left from the standby position A to the inverted position B together with the driven gears 125 and 126.

At this time, the lead wire 128 connecting the nozzle movement motor 121 and the controller 70 is pulled by the nozzle movement motor 121 because the nozzle movement motor 121 is moved together with the suction nozzle 110. That is, the motor connecting portion 128b and the controller connecting portion 128c of the lead wire 128 are released from the wheel 210, and the automatic winding device 120 is moved to the left along with the lead wire 128. 128 is maintained in tension by the force of the nozzle moving motor 121 and the elastic force of the spring 220, the overall length is gradually increased.

As shown in FIG. 7, when the nozzle movement motor 121 reaches the inversion position B, the lead wires 128 are in a state where the lead wires 128 are arranged to be the longest, and the automatic winding device 120 uses the lead wires ( And is positioned approximately above the central portion of the filter frame 90 in a suspended state.

On the other hand, in the retraction mode of the nozzle movement motor 121, the rotating shaft 121b is rotated in the clockwise direction opposite to that in the forward mode, the motor gear 121a is rotated clockwise together with the rotating shaft 121b, The drive gear 123 is rotated in a counterclockwise direction opposite to the motor gear 121a, and the driven gears 125 and 126 are rotated in a clockwise direction opposite to the drive gear 123, and the fixed gear 124 is rotated. ), And the suction nozzle 110 is slid to the right from the reverse position (B) toward the standby position (A) together with the driven gear (125) (126).

At this time, the force for pulling the lead wire 128 by the nozzle movement motor 121 does not act on the lead wire 128 connecting the nozzle movement motor 121 and the controller 70, but only the restoring force of the spring 220. The lead wire 128 is pulled in the direction of the automatic winding device 120. That is, the motor connecting portion 128b and the controller connecting portion 128c of the lead wire 128 are wound around the outer circumference of the wheel 210, and the automatic winding device 120 is moved to the right side together with the lead wire 128. The line 128 is kept tight by the elastic force of the spring 220 and the force sustained by the suction nozzle 110, and the overall length thereof becomes shorter.

When the nozzle movement motor 121 reaches the reversal position B, the lead wire 128 is in a state of being arranged as short as possible. At this time, the automatic winding device 120 is suspended from the lead wire 128. 70).

On the other hand, when the suction nozzle 110 moves left and right as described above, foreign matters in the filter 80 are separated from the filter 80 by the brush 113, and the cleaning fan driven by the cleaning fan motor 181. At the time of rotation of 182, suction force by the cleaning fan 182 is applied to the inside of the hose 170, the inside of the suction duct 135, and the suction nozzle 110, and the foreign matter separated from the filter 80 is The suction nozzle 110, the suction duct 135, the hose 170, and the cleaning fan housings 184 and 185 are sequentially passed through and are sent into the dust collecting container 190.

The foreign matter and air sent into the dust collecting container 190 are separated from the inside of the dust collecting container 190 so that the foreign matter collects in the inner lower portion of the dust collecting container 190 which is not raised toward the upper part of the dust collecting container 190. It is discharged to the outside of the dust collecting container 190 through the air outlet 194.
