For the problems referred to above, the present invention proposes a kind of air-conditioning safety protecting method, device and air-conditioning, uses
May injure user in solving existing air-conditioned indoor fan fan, the problem that air-conditioning degree of protection is low.
The schematic flow sheet of the air-conditioning safety protecting method embodiment one that Fig. 1 provides for the present invention.Such as Fig. 1
Shown in, the air-conditioning safety protecting method that the embodiment of the present invention provides, including:
Step 101: the indoor fan of the detection air-conditioning blower fan electric current when preset running mode；
Concrete, owing in air-conditioning main control module, storage has operating rotating speed and the blower fan electric current of indoor motor
Corresponding relation, this indoor motor is for the operating of drive chamber's inner blower, therefore, at air-conditioning start process and
In running, air-conditioning main control module can automatically detect indoor fan when a certain preset running mode
Blower fan electric current.
This preset running mode may for freezing, heat, dehumidify, any one in the various modes such as ventilation
Kind, under different preset running mode, the operating rotating speed of indoor fan is different, accordingly, and indoor wind
The blower fan electric current of machine also differs.
In general, the refrigeration in air-conditioning, heat, ventilate, different operational modes such as dehumidifying and same
The rotating speed that operational mode difference wind scale is corresponding is all different.Before the top panel of wall hanging machine, cabinet type machine
Plate or air inlet grid are opened onesize, the change of windage that it causes may as, but going out of causing
Air quantity change may be different, then the rotating speed of indoor fan may be different, and the amount of work of indoor fan is also
May be different, curent change is the most different.
Step 102: judge that whether this blower fan electric current and the difference of the mode current of preset running mode are more than pre-
If threshold value；The most then perform step 103, perform step 101 if it is not, return；
Optionally, it is first determined go out air-conditioning preset running mode and this preset running mode that user selectes
Mode current, and then for follow-up compare operation of air conditioner time indoor fan blower fan electric current with this preset run
The mode current of pattern provides precondition.
In actual application, owing to the indoor fan of air-conditioning and outdoor fan are under fixed rotating speed during stable operation
Blower fan electric current be fixing, therefore, when the air inlet structure such as front panel of air-conditioning is opened or the most the normally off
When closing, the windage of indoor fan can be caused to reduce, air-out quantitative change is big, and indoor fan is done manual work and increased, and then
The phenomenons such as the change of blower fan electric current is big occur.
Such as, illustrate, if indoor fan operates in height as a example by wall hanging machine employing PG alternating current generator
Wind state, when its front panel is of completely closed, the blower fan electric current detected is 0.096A, and front wall
When opening 1/4 size, blower fan electric current now is 0.106A, and accordingly, curent change is 0.01A
(10mA)；When front wall opens 1/2 size, blower fan electric current now is 0.116A, accordingly,
Curent change is 0.02A (20mA)；When front wall is fully open, blower fan electric current now is 0.124A,
Accordingly, curent change is 0.028A (28mA).
It is similar to, if indoor fan operates in apoplexy state, when front wall is of completely closed, detects
Blower fan electric current is 0.064A, and when front wall opens 1/4 size, blower fan electric current now is 0.069A,
Accordingly, curent change is 0.005A (5mA)；When front wall opens 1/2 size, wind now
Dynamo-electric stream is 0.074A, and accordingly, curent change is 0.01A (10mA)；Front wall is fully open
Time, blower fan electric current now is 0.079A, and accordingly, curent change is 0.015A (15mA).
If indoor fan operates in low wind conditions, when front wall is of completely closed, the blower fan electric current detected
For 0.044A, and when front wall opens 1/4 size, blower fan electric current now is 0.049A, accordingly,
Curent change is 0.005A (5mA)；When front wall opens 1/2 size, blower fan electric current now is
0.052A, accordingly, curent change is 0.008A (8mA), when front wall is fully open, now
Blower fan electric current be 0.053A, accordingly, curent change is 0.009A (9mA).
Therefore, air-conditioning work is when the different wind scale state of a certain preset running mode, and front panel is opened same
The blower fan curent change of sample its correspondence of size is different, it is however generally that, panel opening before the embodiment of the present invention
The curent change of 1/2 correspondence is as predetermined threshold value, and accordingly, the predetermined threshold value under different wind scale states is different.
But, during for different operational modes or different wind scale state, the predetermined threshold value of setting may be different,
This embodiment of the present invention is also not limited thereof.
Accordingly, blower fan electric current above-mentioned steps 101 detected is electric with the pattern of this preset running mode
Stream contrasts, when the difference of the blower fan electric current Yu mode current judging indoor fan is more than predetermined threshold value,
So show indoor fan operating rotating speed increase, blower fan current change quantity beyond set excursion,
The air inlet structure of air-conditioning is opened or non-normal switching-off.
If judging, the blower fan electric current of indoor fan is less than above-mentioned predetermined threshold value with the difference of this mode current,
Then showing that indoor fan works well, the air inlet mechanism of air-conditioning is in Normal Shutdown state, then continue detection
Indoor blower fan size of current.
Step 103: control room inner blower shuts down.
When air-conditioning occurs that in running the air inlet structure of air-conditioning is opened or the phenomenon of non-normal switching-off
Time, in order to avoid the fan blades of indoor fan is injured user, the embodiment of the present invention is by utilizing main control module control
Indoor fan processed is closed so that it is shuts down, thus protects the personal safety of user, improves air-conditioning
Degree of protection.
The air-conditioning safety protecting method that the embodiment of the present invention provides, directly detects air-conditioning by air-conditioning master control borad

Step 202: judge that whether the indoor fan of the air-conditioning running speed when this preset running mode exists
In the range of preset rotation speed；The most then perform step 203, otherwise, return step 201；
Owing to, in air-conditioning start process, indoor fan just starts running, rotating speed by accelerating slowly, its correspondence
Blower fan electric current is unstable, if the blower fan electric current of now sensing chamber's inner blower, then testing result may be inaccurate,
So, start shooting under air-conditioning is in preset running mode, first determine whether that indoor fan is in this preset running mode
Under running speed whether in the range of preset rotation speed, that is, when after the stabilization of speed of indoor fan, then
The current conditions of the indoor fan of detection air-conditioning.
What deserves to be explained is, preset rotation speed scope be according to indoor fan run well time fluctuation arrange
's.Such as, indoor fan indoor fan rotating speed under high wind state is 1200rpm (rev/min), when
Within the fluctuation 2.5 turns up and down per minute of its rotating speed, then it is believed that its stabilization of speed, that is, high wind state
Time, corresponding preset rotation speed scope can be 1197.5rpm to 1202.5rpm.
Assume that indoor fan indoor fan rotating speed under apoplexy state is 1050rpm, when its rotating speed every point
Clock fluctuates within 2.5 turns up and down, then it is believed that its stabilization of speed, that is, indoor fan is in apoplexy shape
During state, corresponding preset rotation speed scope can be 1047.5rpm to 1052.5rpm.
Accordingly, the indoor fan rotating speed under indoor fan is in low wind conditions is 900rpm, when its rotating speed
Within fluctuation 2.5 turns up and down per minute, then it is believed that its stabilization of speed, that is, indoor fan is in low
During wind state, corresponding preset rotation speed scope can be 897.5rpm to 902.5rpm.
Preset rotation speed scope in the embodiment of the present invention need to be set according to practical situation, transports for difference
The preset rotation speed scope of row mode may be different, the embodiment of the present invention not concrete to preset rotation speed scope
Value is defined.
Step 203: the indoor fan of the detection air-conditioning blower fan electric current when this preset running mode；
If the running speed that indoor fan is when preset running mode meets corresponding preset rotation speed scope, also
That is, after the running speed of indoor fan is stable, then can the blower fan electric current of sensing chamber's inner blower, now examine
The blower fan current ratio measured is more accurate.
Step 204: judge that whether this blower fan electric current and the difference of the mode current of preset running mode are more than pre-
If threshold value；The most then perform step 205, perform step 203 if it is not, return；
Concrete, the mode current of the blower fan electric current detected with this operational mode is compared, if wind
The mode current of dynamo-electric flow ratio preset running mode exceeds the size of predetermined threshold value, then represent wall-mounted sky
Adjust or the air inlet grid of the front panel of cabinet air-conditioner or cabinet air-conditioner does not has normal switching-off, then according to step
Rapid 205 and the scheme of step 206 perform corresponding process.If the size of this blower fan electric current is run with presetting
The mode current of pattern is consistent or blower fan electric current is less than default with the difference of the mode current of preset running mode
Threshold value, then show indoor fan normal operation, now, return step 203, continue sensing chamber's inner blower
Blower fan electric current.
Step 205: stop opening electrostatic precipitation function and nanoe moisturizing degerming functions；
Electrostatic precipitation in air-conditioning is the one of dedusting method, utilize electrostatic field to make gas ionization thus
The air purifying process making dust particles be adsorbed onto on electrode, has the function purifying air.Nanometer water from

And produce charged ion.Owing to most of antibacterials are made up of protein, the charged water that nanoe produces
During contacted with ions antibacterial, the hydrion in bacterioprotein can be taken away, make antibacterial lose activity, Jin Ershi
Existing moisturizing, degerming, the purpose of purification air.
In actual applications, when air-conditioning is started shooting, the running speed at indoor fan reaches to preset and runs mould
Before preset rotation speed scope during formula, that is, do not judging the air inlet structure whether normal switching-off of air-conditioning
Before, control electrostatic precipitation function and nanoe moisturizing degerming functions is closed, if so judging
When going out the blower fan electric current of the indoor fan difference with the mode current of preset running mode more than predetermined threshold value, then
Show the air inlet structure closedown not yet in effect of air-conditioning, now, then stop opening electrostatic precipitation function and nanoe
Moisturizing degerming functions, thus the waste of energy that the repetition opening and closing avoiding above-mentioned functions module causes.
Step 206: control room inner blower shuts down.
When air-conditioning is in start process, the blower fan current anomaly of indoor fan detected, the most directly control
Indoor fan processed shuts down, and then makes user check the closedown situation of air-conditioning air inlet structure in time, thus
Avoid the situation that user is injured by the fan blades of indoor fan, effectively protect the safety of user.
