Relay or two two-way contact relays, in the control 302 positive operation of outdoor fan of controller 202, can make first to touch
Point and the conducting of the 3rd contact, and when controller 202 controls 302 inverted running of outdoor fan, the second contact in four contacts
With the conducting of the 4th contact, vice versa.Outdoor fan 302 is caused by auxiliary winding because of the conducting of relay difference contact
3024 sense of current there occurs change, and the torque direction of auxiliary winding 3024 there occurs change, so as to change outdoor fan
302 rotation direction.
Fig. 5 shows the controlled output time diagram of embodiment according to a third aspect of the present invention.
Describe controlled output sequential in detail with reference to Fig. 4 and Fig. 5.As shown in figure 5, the 1st stage：First control end
402 output high level, the output low level of the second control end 404.Now, because the high level of the output of the first control end 402 is caused
Power supply relay 308 is turned on so that current supply circuit is turned on.Second control end 404 exports low level so that outdoor fan direction turns
Change relay 306 the first contact and the 3rd contact conducting, the sense of current for then flowing through auxiliary winding 3024 be from first end to
Second end, so the positive operation of outdoor fan.When 2nd stage is to reach the first Preset Time between when running, for example, reach 20
Hour~200 hours, the output low level of the first control end 402, fan power outside control power supply relay 308 disconnection chamber stops
Outdoor fan 302, and extend the scheduled time, within this time, outdoor air quantity is gradually reduced, and the second control end 404 keeps defeated
Go out low level.After three Preset Times is reached, the 3rd Preset Time is 5 seconds to 60 seconds, the second control end 404 in the present embodiment
Start to export high level, turn on the second contact of outdoor fan direction switching relay 306 and the 4th contact, in this process
In, outdoor air quantity flow direction is still continuously forward direction, and outdoor air quantity is gradually reduced；Subsequently into the 3rd stage, now, the first control
End processed starts to export high level so that power supply circuit is turned on, and the second control end 2 persistently exports high level, makes outdoor fan direction
Second contact of switching relay 306 and the 4th contact turn on so that the sense of current for flowing through auxiliary winding 3024 changes, room
The traffic direction of outer blower fan changes, so that outdoor air quantity flow direction is changed into reversely, starts the process except foreign matter.When except foreign matter
When time reaches the second Preset Time, the second Preset Time is 1 minute to 10 minutes in the present embodiment, and the first control end 402 is defeated
Go out low level, fan power outside control power supply relay 308 disconnection chamber stops outdoor fan, in delay stage, the second control end
404 persistently export high level, and after three Preset Times is reached, the 3rd Preset Time is 5 seconds to 60 seconds, second in the present embodiment
Control end 404 is changed into exporting low level, turns on the second contact of outdoor fan direction switching relay 306 and the 4th contact,
In the process, outdoor air quantity flow direction is reverse, and outdoor air quantity is gradually reduced；Finally enter the 5th stage, the first control end
402 restart to export high level, and control power supply relay 308 connects outdoor fan power supply, while the output of the second control end is low
Level, turns on the first contact of outdoor fan direction switching relay 306 and the 3rd contact, and now outdoor air quantity flow direction is for just
To.Above procedure is merely illustrative process, and the time in each stage can be adjusted as needed during being somebody's turn to do, and this is several
The individual stage can move in circles, and will not be repeated here.
