According to one embodiment of present invention, described determine described DC fan operation exception in the case of, described control
Unit 206 processed specifically for: obtain the setting speed corresponding with described actual speed；Calculate described actual speed to set with described
Determine the rotating speed difference between rotating speed；Judge whether described rotating speed difference reaches to preset typhoon protection threshold value；In described rotating speed difference
When reaching described default typhoon protection threshold value, stop transmitting speed controling signal to described DC fan, and cut off described direct current
The power supply of blower fan；When described rotating speed difference is not up to described default typhoon protection threshold value, controls described DC fan and continue
Reforwarding row.
When DC fan operation exception, reach predetermined table by the rotating speed difference between actual speed and setting speed
During wind protection threshold value (predetermined typhoon protection threshold value can be configured according to the actual requirements), stop transmitting rotating speed control to DC fan
Signal processed, and cut off the power supply of DC fan, thus it is out of service, to avoid in air-conditioner to control DC fan in time
Device is damaged, and whole process reaches the duration of predetermined typhoon protection threshold value without detecting rotating speed difference, to avoid detection
Overlong time and uncontrollable DC fan is shut down in time.
According to one embodiment of present invention, described control unit 206 is additionally operable to: when receiving described DC fan
During open command, close the power supply of described DC fan, and transmit rotating speed control to described DC fan after the second duration
Signal processed, to control the operation of described DC fan；When detecting under described air-conditioner is in standby or stopped status, cut off institute
State the power supply of DC fan.
The DC fan of air-conditioner runs the most always, when receiving the open command to DC fan, closes direct current
The power supply of blower fan, and the second duration (the second duration is the second duration after the power supply of Guan Bi DC fan, the
Two durations can be configured according to the actual requirements) time to DC fan transmit speed controling signal with control DC fan run,
When making only DC fan is had use demand, just control DC fan startup optimization, and be in standby at air-conditioner or stop
Under machine state, the power supply of cut-out DC fan, so that DC fan does not start or stop operation, significantly reduces air-conditioning
The power consumption of device system.
Fig. 3 shows the schematic block diagram of air-conditioner according to an embodiment of the invention.
As it is shown on figure 3, air-conditioner 300 according to an embodiment of the invention, including: the control of air-conditioner as shown in Figure 2
Device 200.
Below in conjunction with Fig. 4 and Fig. 5, technical scheme is described further.
As shown in Figure 4, air-conditioner includes controller MCU (Microcontroller Unit) 402, DC fan power supply control
Circuit 404 processed, DC fan rotating-speed control circuit 406, DC fan Rotating speed measring circuit 408 and DC fan 410.
Wherein, the DC fan control method of air-conditioner outdoor unit has: 1) controller MCU controls PWM to DC fan
The control of (Pulse Width Modulation, pulse width modulation) signal；2) controller MCU is to DC fan speed feedback
The parsing of signal；3) control of DC fan power supply；4) the controller MCU parsing to Typhoon Information.
DC fan control circuit is divided into three control circuits: one is that (power supply controls DC fan power control circuit 404
Circuit can be on-off circuit, such as: relay, controllable silicon etc.)；Two is direct current wind rotating-speed control circuit 406；Three is direct current wind
Machine Rotating speed measring circuit 408.
DC fan power supply and rotating speed are controlled and detect by controller MUC402 in real time, and are sentenced by controller MCU
The on off state of disconnected DC fan power control circuit 404, runs for DC fan and provides power supply.If DC fan needs fortune
Turn, then before DC fan operates, 15S (second) closes DC fan power control circuit.When the DC fan of off-premises station is by typhoon
During operating, at this moment relay disconnects, and prevents the current reflux that DC fan generating produces on converter, converter is caused damage
Bad.
Concrete control process is as it is shown in figure 5, include:
Step 502, the DC fan control interface of controller MCU is to boot-strap information, and controller MCU is to DC fan
It is controlled.Specifically, under air-conditioner standby, stopped status: DC fan power supply disconnects, and DC fan does not starts；Work as air-conditioning
When device detects power-on command, before DC fan is opened, 15S closes DC source, normally starts DC fan.
Step 504, closes DC fan power control circuit.
Step 506,15S (the i.e. second duration, specifically can arrange according to the actual requirements) sends the PWM of DC fan rotating speed afterwards
Control signal.
Step 508, it is judged that the wind speed of DC fan is the most normal, if so, performs step 510；Otherwise perform step 522.
Step 510, the feedback signal of monitoring DC fan calculates actual speed in real time.
Step 512, compares whether actual speed reaches default typhoon protection threshold value with the speed discrepancy of setting speed, if so,
Perform step 514；Otherwise, step 516 is performed.
Step 514, speed discrepancy reaches to preset typhoon protection threshold value, and continues for some time (the i.e. first duration).As set
The speed discrepancy of rotating speed and actual speed more than or equal to 300rpm and persistently more than 2min (minute) time, air-conditioner the most out of service
And DC fan, it is then turned off DC fan power supply, enters protection.
Step 516, DC fan continues to run with.
Step 518, disconnects the control power supply of DC fan, and MCU stops sending DC fan pwm control signal.
Step 520, air-conditioner outdoor unit enters typhoon protection.
Step 522, compares whether actual speed reaches default typhoon protection threshold value with the speed discrepancy of setting speed, if so,
Perform step 524；Otherwise, step 526 is performed.
Step 524, disconnects the control power supply of DC fan, and MCU stops sending DC fan pwm control signal.
Step 526, DC fan continues to run with.
Step 528, air-conditioner outdoor unit enters typhoon protection.
In the above-described embodiments, under typhoon weather environment, the DC fan of direct-flow air conditioner device is carried out protection process, anti-
Only air-conditioning equipment device burns, and improves the reliability of air-conditioner, brings the air-conditioning service of more comfortableization to user.
Technical scheme being described in detail above in association with accompanying drawing, the present invention proposes the control of a kind of new air-conditioner
Scheme processed, is controlled the running status of the DC fan of air-conditioner, to prevent in air-conditioner under typhoon weather environment
Device is damaged, improves the reliability of air-conditioner, promotes the experience of user.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
