Embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
As shown in figure 1, first realities of the Fig. 1 for the method for air conditioner chamber's inner blower motor speed influence factor self-inspection of the present invention Apply the flow chart of example.The method for air conditioner chamber's inner blower motor speed influence factor self-inspection that the present embodiment is mentioned, including it is following Step:
Step S10, the operating voltage of detection blower fan motor and the actual speed V of blower motor;
The hardware of the present embodiment realizes that environment can be for the blower motor rotating speed influence factor inside air conditioner certainly Checking device, or the directly circuit such as main control unit, detection unit inside air conditioner are constituted, or can be connected with air conditioner External device (ED).The self-checking unit can be using voltage detecting circuit come the operating voltage of detection blower fan motor, in air conditioner, the work It can be line voltage to make voltage.,, should when blower motor is run with velocity feedback circuits in capacitance operation asynchronous machine Velocity feedback circuits can be by the speed feedback signal of blower motor to self-checking unit, and self-checking unit can detection blower fan motor at any time Actual speed, and then realize the real-time monitoring to motor operation situation.
After operating voltage is obtained, operating voltage place is found from the indoor set running status corresponding table simulated in advance Exemplified by list item corresponding to voltage range, following table:
In upper table, when electric capacity is undamped and air conditioner is in dustless state, as specified running status, and to decay most Big value is exemplified by 20%.Assuming that the operating voltage detected is 210 volts, then belong to 212 ± 2.5 volts of voltage ranges, in relatively rotating speed When, judge to influence the factor of motor speed using the corresponding rotating speed of 212 ± 2.5 volts of voltage ranges.
Step S20, as V >=VmaxWhen, determine that blower motor is in dust-full state, export the prompt message of dust removal process, its Middle VmaxElectric capacity for blower motor is undamped and voltage range where operating voltage is corresponding maximum turn when being in dust-full state Speed;
Assuming that actual speed V=1330 rev/min measured, the rotating speed is more than in 212 ± 2.5 volts of voltage ranges, and electric capacity is without declining Subtract and 1310 ± 10 revs/min of maximum (top) speed when air conditioner is in dust-full state, then illustrate that blower motor is in full dirt state, need Want timely dedusting.Because during populated with impurity, rotation speed of fan can increase, and electric on the heat exchanger and inlet air filter screen of air conditioner When holding decay, rotation speed of fan can be reduced, and the rotation speed of fan now measured then illustrates laying dust considerably beyond the maximum (top) speed of simulation The decay of influence specific capacitance big many of influence, need not temporarily consider capacitance fade.
Step S30, as V≤Vmin' when, determine that the capacitance fade value of blower motor is more than decay maximum, electricity is changed in output The prompt message of appearance, wherein Vmin' for blower motor capacitance fade value be equal to decay maximum and in dustless state when work The corresponding minimum speed of voltage range where voltage.
Assuming that actual speed V=1000 rev/min measured, the rotating speed is less than in 212 ± 2.5 volts of voltage ranges, capacitance fade 1210 ± 10 revs/min of minimum speed when value is equal to decay maximum and is in dustless state, then illustrate the electric capacity of blower motor Attenuation degree is larger, it is necessary to change electric capacity.During due to capacitance fade, rotation speed of fan can be reduced, and in air conditioner populated with impurity When, rotation speed of fan can increase, and the rotation speed of fan now measured has been far smaller than the minimum speed of simulation, then illustrates capacitance fade Influence to influence greatly many than laying dust, need not temporarily consider that laying dust influences.

As shown in Fig. 2 second realities of the Fig. 2 for the method for air conditioner chamber's inner blower motor speed influence factor self-inspection of the present invention Apply the flow chart of example.The present embodiment is based on embodiment illustrated in fig. 1, and step S30 is specifically included:
Step S31, as V≤Vmin' when, export the prompt message of dust removal process;
The present embodiment considers capacitance fade and laying dust is impacted to rotation speed of fan, as V≤Vmin' when, adopt first Dust suppression is taken, first allows air conditioner to be in dustless state, then judges whether blower fan electric capacity needs replacing again.Assuming that the reality measured Border rotating speed V=1200 rev/min, the rotating speed is less than capacitance fade value in 212 ± 2.5 volts of voltage ranges and is equal to decay maximum and place 1210 ± 10 revs/min of minimum speed when dustless state, now, first points out related personnel to carry out dust removal process, to exclude product The rotating speed problem that dirt factor is caused.
Step S32, after dust removal process is completed, the actual speed V ' of detection blower fan motor again;
After dust removal process is completed, air conditioner is in the rotating speed of dustless state, again detection blower fan motor, for example, now turn Speed is 1190 revs/min.

The present embodiment is for Vmin' < V < VmaxSituation, dust suppression is taken first, first allow air conditioner be in dustless shape State, then judges whether blower fan electric capacity needs replacing again.Assuming that actual speed V=1250 rev/min measured, the rotating speed is more than 1210 ± 10 revs/min, and less than 1310 ± 10 revs/min, now, first point out related personnel to carry out dust removal process, to exclude laying dust The rotating speed problem that factor is caused.
Step S50, after dust removal process is completed, the actual speed V ' of detection blower fan motor again;
After dust removal process is completed, air conditioner is in the rotating speed of dustless state, again detection blower fan motor, for example, now turn Speed is 1235 revs/min.
Step S60, according to the actual speed V ' detected again, determines the capacitance fade value of blower motor;
, it is necessary to calculate actual capacitance fade value after rotating speed is detected again, capacitance fade value=20% ×(| 1275- 1235|)/(| 1275-1210 |)=12.3%.
Step S70, when the capacitance fade value of blower motor is more than drop threshold, the prompt message of electric capacity is changed in output, Wherein, drop threshold is less than or equal to decay maximum.
The actual capacitance fade value for calculating acquisition is compared with drop threshold, if capacitance fade value is more than decay maximum Value, for example, default drop threshold is 10%, actual capacitance pad value is 12.3%, then actual capacitance pad value is more than decay threshold Value is, it is necessary to point out related personnel to change electric capacity in time.
The present embodiment judges whether capacitance fade value is more than drop threshold by calculating actual capacitance pad value, to determine Whether need to change electric capacity, and point out related personnel in time, the rotary speed unstabilization for being conducive to quick exclusion capacitance fade factor to cause It is fixed, be conducive to improving air conditioner stability.In addition, when capacitance fade value is less than or equal to drop threshold, electric capacity declines Subtract degree be not it is very serious, can be temporarily without handling.
