Indoor environment temperature when pattern.
Preferably, when detecting that the difference between instant environment temperature and initial indoor environment temperature is less than or equal to
When A, inner blower rotating speed △ R1 are reduced；When detecting that the difference between instant environment temperature and initial indoor environment temperature is more than
Or when equal to B, inner blower rotating speed △ R1 are improved.
Preferably, environment temperature and initial indoor environment temperature are more primary at interval of the t1 times immediately.
Preferably, when the difference that detect between instant environment temperature and initial indoor environment temperature be located at A and B it
Between when, make inner blower keep current rotating speed.
Preferably, A is -2, B 2.
Preferably, t1 is 15s.
Preferably, initial indoor environment temperature obtained before adjusting inner blower rotating speed after opening defrost pattern for the first time or
It is obtained while first adjustment inner blower rotating speed.
Preferably, inner blower is stepless speed regulation type wind turbine.
Preferably, defrosting control method further includes：After opening defrost pattern, interior electric auxiliary heating is opened.
It applies the technical scheme of the present invention, defrosting control method includes：Open defrost pattern；Start inner blower；Detection is
When environment temperature, and instant environment temperature is compared with initial indoor environment temperature, inner blower is adjusted according to comparison result
Rotating speed, so that indoor environment temperature is maintained in preset temperature range, wherein initial indoor environment temperature be start defrost pattern
When indoor environment temperature.The present invention opens inner blower when air conditioner is in defrost pattern, by adjusting inner blower
Rotating speed makes indoor environment temperature be maintained in a reasonable range, makes user that can obtain preferable usage experience always,
In addition, inner blower can accelerate the transmission of heat so that heat meets defrost demand, accelerates the speed of defrost, improves defrost effect
Rate.
Description of the drawings
Fig. 1 is the flow chart of the rotation speed of fan control method of the embodiment of the present invention.
Specific implementation mode
Present invention is further described in detail in the following with reference to the drawings and specific embodiments, but not as the limit to the present invention
It is fixed.
Shown in Figure 1, according to an embodiment of the invention, defrosting control method includes：Open defrost pattern；Detection is instant
Environment temperature, and instant environment temperature is compared with initial indoor environment temperature, inner blower is adjusted according to comparison result
Rotating speed makes indoor environment temperature be maintained in preset temperature range, wherein initial indoor environment temperature is when starting defrost pattern
Indoor environment temperature.
The present invention opens inner blower when air conditioner is in defrost pattern, and the rotating speed by adjusting inner blower makes
Indoor environment temperature is maintained in a reasonable range, makes user that can obtain preferable usage experience always, in addition, interior wind
Machine can accelerate the transmission of heat so that heat meets defrost demand, accelerates the speed of defrost, improves defrost efficiency.
It, can be by inner blower rotating speed and instant environment temperature and initial indoor environment when internal rotation speed of fan is adjusted
Magnitude relationship between temperature combines, by being compared to adjust to instant environment temperature and initial indoor environment temperature
The rotating speed of inner blower is avoided in defrost since inner blower rotation impacts excessive on indoor temperature and influences user experience,
Carry out the mode that internal rotation speed of fan is adjusted especially by instant environment temperature and the magnitude relationship of initial indoor environment temperature
Can there are many, such as be increased by inner blower rotating speed when instant environment temperature is more than initial indoor environment temperature, reduce instant
Environment temperature just reduces inner blower rotating speed when instant environment temperature is less than initial indoor environment temperature, improves instant environment temperature
Degree, to ensure that instant environment temperature remains at a rational temperature value so that while improving defrost efficiency, use
Family can also obtain preferable usage experience.
In the present embodiment, for the adjustment of rotational speed mode of inner blower specifically, when detect instant environment temperature with just
When difference between beginning indoor environment temperature is less than or equal to A, inner blower rotating speed △ R1 are reduced；When detecting instant environment temperature
When difference between degree and initial indoor environment temperature is greater than or equal to B, inner blower rotating speed △ R1 are improved.In air-conditioning four-way valve
When commutation enters defrost pattern, inner blower is blowed with slow-speed of revolution R1, while by instant environment temperature and initial indoor ring
Border temperature is compared, and is adjusted according to the internal rotation speed of fan of difference.
Size of the difference herein should be in a smaller range, during avoiding inner blower adjustment of rotational speed, i.e.,
When environment temperature and initial indoor environment temperature between deviation it is excessive and cause the uncomfortable of indoor temperature.
In the present embodiment, initial indoor environment temperature is T0, and instant environment temperature is T1, instant environment temperature with it is initial
The difference of indoor environment temperature is that then inner blower rotating speed reduces △ R1 to △ T, △ T≤- 2 (△ T=T1-T0), ensures -2 ＜ △ T,
As 2≤△ T, then inner blower rotating speed improves △ R2, ensures △ T ＜ 2.It, can be by instant environment temperature by this kind of regulative mode
Degree T1 is remained between T0-2 to T0+2, to keep the comfort of indoor environment temperature.
Instant environment temperature and initial indoor environment temperature are more primary at interval of the t1 times, to reduce comparison frequency
While, it can be adjusted in time according to the internal rotation speed of fan of instant environment temperature, interval time t1 herein is unsuitable long,
Also unsuitable too short, it is ensured that instant environment temperature is fully adjusted, and also to guarantee in time to carry out instant environment temperature
Adjustment.
When detecting that the difference between instant environment temperature and initial indoor environment temperature is between A and B, make interior
Wind turbine keeps current rotating speed, to ensure that inner blower can effectively accelerate defrost efficiency, while will not cause shadow to indoor temperature
It rings.
Initial indoor environment temperature is being obtained before adjusting inner blower rotating speed or is being obtained while adjusting inner blower rotating speed, this
When acquired cup for it in more rational temperature, that is, temperature that human body feels comfortable, since this temperature is interior wind
Temperature when temperature or inner blower before machine adjustment adjust, temperature at this time will not be influenced by inner blower adjustment, be tied
Fruit is more accurate.
Inner blower is stepless speed regulation type wind turbine, internally can carry out continuous stepless changing by rotation speed of fan, can ensure interior
The continuity that wind turbine adjusts instant environment temperature, to be more accurately adjusted to instant environment temperature so that immediately
Environment temperature can be accurately maintained between T0-2 to T0+2 always.
Defrosting control method further includes：After opening defrost pattern, interior electric auxiliary heating is opened.Interior electric auxiliary heating can be sky
It adjusts device to carry out defrost and supplemental heat is provided, ensure that enough heats can be absorbed into when defrost, reduce air conditioner defrost to Indoor Temperature
The influence of degree, further improves defrost efficiency.
Certainly, it is above the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art
For, under the premise of not departing from general principles, several improvements and modifications can also be made, these improvements and modifications
It is considered as protection scope of the present invention.
