The adhesive tape 7 and the filter screen 2 are positioned between the pressing rotating shaft 4 and the supporting rotating shaft 9 of the adhesive tape cleaning assembly 6, and the driving device drives the pressing rotating shaft 4 in the adhesive tape cleaning assembly 6 to be close to the filter screen 2, so that the adhesive tape 7 is tightly contacted with the filter screen 2 under the action of the pressing rotating shaft 4 and the supporting rotating shaft 9.
The application uses the viscosity of the adhesive tape 7 to remove the deposited ash on the filter screen 2, and the adhesive tape 7 is contacted with the filter screen 2, so that the surface of the filter screen 2 is not damaged.
The driving device comprises three motors, the motor I drives the first rotating shaft 8 to rotate, the motor III drives the adhesive tape recycling rotating shaft 5 to rotate, and the motor II drives the pressurizing rotating shaft 4 of the adhesive tape cleaning assembly 6 to approach and separate from the filter screen 2 along the direction vertical to the surface of the filter screen 2.

The motor I then drives the first shaft 8 to rotate in a counterclockwise direction as viewed in fig. 3, so that the adhesive tape cleaning assembly 6 moves upward under the drive of the transmission 10.
While the adhesive tape cleaning assembly 6 moves, the motor III drives the adhesive tape recycling rotating shaft 5 to rotate, and the pressurizing rotating shaft 4 and the adhesive tape rotating shaft 3 are linked through the adhesive tape 7.
The new adhesive tape is unwound from the adhesive tape rotating shaft 3, and after contacting the filter screen, the dust on the filter screen is stuck, and the adhesive tape stuck with dirt is wound into the adhesive tape recycling rotating shaft 5.

Resetting the adhesive tape cleaning assembly:
the motor II is reversed to drive the pressurizing rotating shaft 4 in the adhesive tape cleaning assembly 6 to be separated from the filter screen 2, and the supporting rotating shaft 9 is kept motionless.
The motor I then drives the first shaft 8 to rotate clockwise as shown in fig. 3, and the driving device 10 then drives the tape cleaning assembly 6 to move downwards until the tape cleaning assembly 6 returns to the initial position.
The invention also provides a control method of the driving device of the self-cleaning device of the indoor unit of the air conditioner.
The first method is a control method using a travel switch, wherein the travel switch S2 and the travel switch S1 are arranged at the start point and the end point of the travel of the tape cleaning assembly 6, and specifically comprises the following steps:
step1: the control system starts a cleaning time sequence after receiving a cleaning signal sent by the remote controller or the panel, and the driving device drives the adhesive tape cleaning assembly 6 to move relative to the filter screen 2 along a first direction;
step 2: when the tape cleaning assembly 6 triggers the travel switch S1, the "cleaning sequence" ends, the "reset sequence" starts, and the driving device drives the tape cleaning assembly 6 to move in a second direction opposite to the first direction;
step 3; when the tape cleaning assembly 6 triggers the travel switch S2, the "reset sequence" ends and the motor in the drive stops rotating.
The cleaning sequence includes the steps of:
step1: the motor II rotates positively to drive the pressurizing rotating shaft 4 in the adhesive tape cleaning assembly 6 to approach and contact the filter screen along the direction vertical to the surface of the filter screen;
Step2: after the motor II rotates positively T1, the motor II stops rotating, and the motor I rotates positively to drive the adhesive tape cleaning assembly 6 to move downwards; meanwhile, the motor III controls the tape recycling rotating shaft 5 to rotate clockwise;
on the premise of speed determination and travel determination, the time T1 required by the motor II to drive the adhesive tape cleaning assembly 6 to leave/approach the filter screen can be calculated, and the time T1 is set in the control system in advance.
The adhesive tape 7 is closely contacted with the surface of the filter screen 2 in the cleaning process, so that the movement linear speed of the adhesive tape 7 is consistent with the movement linear speed of the adhesive tape cleaning assembly 6.
The adhesive tape running speed is too slow, ash on the adhesive tape is too much, the adhesive tape loses viscosity, the ash removal effect is poor, the adhesive tape running speed is too fast, the adhesive tape is underutilized, the adhesive tape is wasted, the replacement time of the adhesive tape is shortened, and therefore the adhesive tape running speed is consistent with the running speed of the adhesive tape cleaning assembly 6, the cleaning effect is good, and the adhesive tape is saved.
The reset sequence comprises the following steps:
step1: the motor I stops rotating, and the motor III stops rotating;
step2: the motor II is reversed to drive the pressurizing rotating shaft 4 in the adhesive tape cleaning assembly 6 to separate from the filter screen along the direction vertical to the surface of the filter screen;
step3: after the motor II reverses the rotation T1, the motor I reverses to drive the adhesive tape cleaning assembly 6 to move downwards, and the adhesive tape cleaning assembly 6 resets.
The second is a control method for controlling the whole process through time, firstly, according to the rotating speed of the motor, the running time of each motor is calculated according to the movement travel of each component. And the motor II drives the adhesive tape cleaning assembly 6 to leave/approach the filter screen for a time T1, the motor I drives the filter screen to move upwards/downwards for a time T2, and the movement time of the motor III in the cleaning time sequence is the same as that of the motor I.
The method specifically comprises the following steps:
step1: the control system starts a cleaning time sequence after receiving a cleaning signal sent by the remote controller or the panel, and the driving device drives the adhesive tape cleaning assembly 6 to move relative to the filter screen 2 along a first direction;
step2: after the time T1+ T2 passes, the cleaning time sequence is ended, the reset time sequence is started, and the driving device drives the adhesive tape cleaning assembly 6 to move along a second direction opposite to the first direction;
step 3; after the lapse of time t1+t2, the "reset timing" ends.
The cleaning sequence includes the steps of:
step1: the motor II rotates positively to drive the pressurizing rotating shaft 4 in the adhesive tape cleaning assembly 6 to approach and contact the filter screen 2 along the direction vertical to the surface of the filter screen 2;
step2: after the motor II rotates positively T1, the motor II stops rotating, and the motor I rotates positively to drive the adhesive tape cleaning assembly 6 to move upwards; meanwhile, the motor III controls the tape recycling rotating shaft 5 to rotate clockwise;
Step3: after the motor I rotates forward by T2, the motor I stops rotating, and the motor III stops rotating.
The adhesive tape 7 is closely contacted with the surface of the filter screen 2 in the cleaning process, so that the movement linear speed of the adhesive tape 7 is consistent with the movement linear speed of the adhesive tape cleaning assembly 6.
The adhesive tape running speed is too slow, ash on the adhesive tape is too much, the adhesive tape loses viscosity, the ash removal effect is poor, the adhesive tape running speed is too fast, the adhesive tape is underutilized, the adhesive tape is wasted, the replacement time of the adhesive tape is shortened, and therefore the adhesive tape 7 running speed is consistent with the adhesive tape cleaning assembly 6 running speed, the cleaning effect is good, and the adhesive tape is saved.
The reset sequence comprises the following steps:
step1: the motor II is reversed to drive the pressurizing rotating shaft 4 in the adhesive tape cleaning assembly 6 to separate from the filter screen along the direction vertical to the surface of the filter screen;
step2: after the motor II rotates reversely T1, the motor II stops rotating, and the motor I rotates reversely to drive the adhesive tape cleaning assembly 6 to move downwards, and the adhesive tape cleaning assembly 6 resets;
step3: after motor I reverses T2, motor I stops rotating.
