Survey the move distance of connecting shaft；Movement according to the relationship of move distance and stroke of the connecting shaft in a stroke to connecting shaft
Carry out gearshift adjustment.
Different variable motions is carried out according to different move distances by controlling connecting shaft, can make the company of cleaning device
Spindle has different revolving speeds in the process of movement, so that effect of the condensed water being located in connecting shaft due to rotator inertia,
Connecting shaft can be more easily thrown away out of connecting shaft, and is thrown on heat exchanger, improve condensed water throws away efficiency,
Even if the velocity of rotation of connecting shaft it is very slow it is also ensured that condensed water can have it is enough throw away active force, to improve cold
The utilization efficiency of condensate ensure that the cleaning effect on heat exchanging device surface.
Speed change tune is carried out to the movement of connecting shaft according to the relationship of move distance and stroke of the connecting shaft in a stroke
The step of section includes: when the displacement for detecting connecting shaft is less than L, and control connecting shaft is run with acceleration mode；When the company of detecting
When the displacement of spindle is greater than L, control connecting shaft is run with deceleration regime.In the rigid setting in motion of connecting shaft, control connecting shaft with
Acceleration mode operation, can make the revolving speed fast lifting of connecting shaft, accelerate the cleaning speed on heat exchanging device surface, while can be square
Just the quick of condensed water throws away.When connecting shaft moves to setting displacement L, connecting shaft reduces speed now movement, can make connecting shaft
Revolving speed gradually decrease, reduce speed when connecting shaft moves to end of travel, reduce inertia when connecting shaft rotational motion and make
Firmly, reducing impact of the connecting shaft to driving mechanism, can also due to the variation of speed during connecting shaft retarded motion
So that condensed water is more easier to be thrown out of to heat exchanger surface, with one same-action of Clean Brush for cleaning, heat exchanging device is cleaned.
Preferably, when control connecting shaft is run with deceleration regime, revolving speed is reduced to 0 when control connecting shaft reaches terminal,
It can make the precise and stable operation of connecting shaft, and realize that nature turns to stop, connecting shaft is avoided to continue movement when reaching stroke end to drive
Motivation is configured to impact, and effective protection driving mechanism, the connection structure also effectively reduced between connecting shaft and driving mechanism is received
The impact arrived improves the service life of cleaning device.

n2.L1 herein can be set according to the actual situation, can be function relevant to the radius of gyration of connecting shaft, Huo Zheyou
User or production firm's sets itself.
When connecting shaft, which turns to terminal revolving speed, is reduced to 0, changes connection rotational axis direction after stopping the t1 time, make to connect
Axis is rotated backward with the revolving speed of n1.Stopping the t1 time can be such that driving mechanism stops completely, avoid being directly opposite movement to driving
Mechanism causes greater impact, to form effective protection to driving mechanism.T1 herein is, for example, 3s.
Preferably, when starting the self-cleaning function of outdoor machine of air-conditioner, reset operation is first carried out, connecting shaft is controlled and is turned with n1
Speed starts to move to reset position, and when detecting connecting shaft at a distance from reset position is 0, judgement has resetted.Due to production
Or the reasons such as rigging error are easy to produce kinematic error in connecting shaft rotation process, by being resetted to connecting shaft,
It can effectively eliminate error, guarantee that connecting shaft can accurately in place, improving connecting shaft precise and stable can run.
In the present embodiment, connecting shaft can rotate setting by gear on rack gear, and the total length of middle rack is S,
The radius of gear is r, and it is r that reset terminal, which resets distance, and the buffer distance of the other end is 2r, and the maximum displacement of gear is S-2r, tooth
The maximum displacement of wheel is divided into N parts, L1=(S-3r)/N, L=(S-3r)/2.
The reset terminal of rack gear is provided with displacement detector, according to move distance of the connecting shaft in a stroke and stroke
The step of relationship carries out gearshift adjustment to the movement of connecting shaft includes: when the displacement S1 < (S-3r)/2 and direction that detect are remote
When from displacement detector, the revolving speed of every distance by (S-3r)/N, gear improves n2；As the displacement S1 >=(S- detected
When 3r)/2 and direction is far from displacement detector, the revolving speed of every distance by (S-3r)/N, gear reduces n2, arrives S-3r's
