The current operating condition of air conditioner, can be cooling condition, heating condition, air-supply operating condition and dehumidifying operation work
Condition etc..The current operating condition of air conditioner, can by parameters such as indoor/outdoor environment temperature, indoor/outdoor ambient humidities and
The corresponding relation of known parameter and operating condition and obtain.
When air conditioner opens automatically cleaning processing function, the automatically cleaning processing for performing heat exchanger, air conditioner should be detected first
Current operational mode, if the current operational mode of air conditioner is other operational modes in addition to refrigeration mode, need
It is refrigeration mode by the non-brake method mode adjustment of air conditioner, is provided with the indoor set heat exchanger for air conditioner and produce the temperature for coagulating frost
Condition.If the current operational mode of air conditioner is refrigeration mode, keep present mode constant.
In some optional embodiments, when the current operational mode of air conditioner is non-brake method pattern, for example, heat
During pattern, air conditioner is adjusted to refrigeration mode, and control air conditioner in cooling mode run time no less than default operation
Time, with the coil temperature of cooling air conditioner indoor set heat exchanger, further reduce coil temperature and reach the temperature that can coagulate frost
Degree.This is due to that the coil temperature of indoor set heat exchanger in a heating mode is higher, when heating mode is converted into refrigeration mode
Afterwards, the coil pipe of indoor set heat exchanger needs the regular hour to be cooled, and one can be run in cooling mode in air conditioner for this
Follow-up detection is carried out again after the section time, when air conditioner meets the unlocking condition of automatically cleaning pattern, is then turned on air conditioner oneself
Cleaning mode, perform the automatically cleaning processing of indoor set heat exchanger.
S104, detect the first current value of the rotating speed and motor of the motor of the indoor set blower fan of air conditioner under the rotating speed.
S106, first current value of the motor under the rotating speed is compared with the first pre-set current value under the rotating speed
Compared with if the first current value is less than or equal to the first pre-set current value, the automatically cleaning pattern of unlatching air conditioner, execution indoor set changes
The automatically cleaning processing of hot device.
As air conditioner is for a long time in use, the dust, the impurity that are deposited on the coil pipe of the indoor set heat exchanger of air conditioner
Also more and more, the cleannes of heat exchanger are less and less, cause windage to increase, and the air quantity into blower fan can accordingly reduce, and work as wind
During resistance increase, the load of motor correspondingly increases, and electric current reduces therewith.Usually, motor its load under certain rotating speed is true
Fixed, if the load of motor increases under same rotational speed, electric current reduces, then illustrates that the intake of indoor set blower fan reduces, indoor
The cleannes of machine heat exchanger decline.
To judge that the cleannes of indoor set heat exchanger decline degree, it is first pre- under different rotating speeds that motor need to be set in advance
If current value, the first pre-set current value can be embedded in advance in control program initial stage of development, and first pre-set current value can correspond to
The current value of motor when intake of the indoor set blower fan under certain rotating speed is particular value.
, it is necessary to first obtain the first predetermined current under the rotating speed before the first current value and the first pre-set current value is compared
Value.Specifically, the air conditioner rotating speed of the motor of corresponding indoor set blower fan and electricity corresponding to the rotating speed under different operating conditions
First pre-set current value of machine can be pre-stored within the database in air conditioner, by the rotating speed and database of the motor of detection
The rotating speed of motor matched, find under the rotating speed corresponding to the first pre-set current value, then by motor under the rotating speed the
One current value be less than compared with the first pre-set current value under the rotating speed, when first current value of the motor under the rotating speed or
It is more equal to the dust for during the first pre-set current value, illustrating to deposit on the coil pipe of indoor set heat exchanger under same rotational speed, it is necessary to and
Shi Qingli.Now, air conditioner can open automatically cleaning pattern, perform the automatically cleaning processing of indoor set heat exchanger.Thus achieve sky
Automatic opening of the device automatically cleaning pattern in right times is adjusted, the automatically cleaning of indoor set heat exchanger can be completed without user's operation,
Lift the usage experience of user.
Especially, air intake when the first pre-set current value can be run according to indoor set blower fan by motor with the driving of certain rotating speed
The attenuation degree of amount and set.Specifically, the first pre-set current value is that indoor set blower fan drives operation by motor with certain rotating speed
When theoretical intake be decreased to the current value of motor during the first default intake under the corresponding rotating speed.Because motor is with one
When determining rotating speed operation driving indoor set blower fan and rotating, what its theoretical intake was to determine, because different type of machines air duct structure not to the utmost
It is identical, the blower fan of the indoor set of different type of machines by the motor of certain rotating speed drive theoretical intake during operation be it is different,
In air conditioner automatically cleaning control program initial stage of development, indoor set blower fan is calculated by certain rotating speed according to indoor set air duct structure
Theoretical intake during motor driving operation.
When indoor set blower fan is driving intake during operation to be decreased to the first default intake by the motor of same rotational speed
When, now the current value of the motor of corresponding indoor set blower fan is the first pre-set current value, and the first default intake can be reason
By the 15%~25% of intake, alternatively, the first default intake can be the 20% of theoretical intake.It that is to say, work as interior
When first current value of the motor of machine blower fan under the rotating speed is less than or equal to the first pre-set current value, illustrate indoor set blower fan
Intake loses, for example, loss 20%, now, illustrates that the coil pipe deposition dust of indoor set heat exchanger is more, it is necessary to open air-conditioning
The automatically cleaning pattern of device, perform the automatically cleaning processing of indoor set heat exchanger.
Especially, before the self-cleaning function of air conditioner is opened, air conditioner also can determine whether the motor of indoor set blower fan
Whether first current value is less than or equal to the duration of the first pre-set current value more than the first preset time, such as first default
Time is 3 minutes, when the first current value of the motor of indoor set blower fan is less than or equal to the duration of the first pre-set current value

Specifically, when coil temperature is more than default coil temperature, the cold medium flux of air conditioner is reduced so that evaporating pressure
Reduce, refrigerant boiling heat absorption, reduce the coil surface temperature of indoor set heat exchanger.In the present embodiment, can be throttled by reducing
The aperture of device reduces the cold medium flux of air conditioner, and throttling arrangement is expansion valve, when adjusting cold medium flux, typically passes through regulation
The step number of expansion valve adjusts cold medium flux.
To cause the coil surface of heat exchanger to coagulate, white or solidifying ice is uniform, and the coil surface of heat exchanger can be correspondingly arranged hairbrush,
Before air conditioner carries out automatically cleaning pattern or enters automatically cleaning pattern, hairbrush can the controlled coil surface brush in heat exchanger
It is dynamic so that the condensed water of coil surface can be evenly distributed, make it that it is uniform that coil surface coagulates white or solidifying ice, carry out solidifying frost with
And during defrost, hairbrush controlled can also swipe in coil surface, so as to improve the cleaning effect of heat exchange coil.
When coil temperature is less than default coil temperature, coil temperature reaches the temperature of solidifying white or solidifying ice, is remaining certain
Time, such as 5 minutes, the surface of coil pipe can fully coagulate white or solidifying ice.After coil surface covers frost layer or ice sheet, air-conditioning
Device carries out defrosting processing, so as to complete the surface cleaning of indoor set heat exchanger coil pipe.When air conditioner carries out defrosting processing, compression
Machine can shut down, and indoor set blower fan continues to run in the state of original rotating speed so that and air conditioner is operated under power save mode,
Defrosting operation can be favorably accomplished.
In some optional embodiments, after defrosting operation is completed, the motor of also detectable indoor set blower fan is in original
There is the current value under rotating speed, obtain the second current value under the rotating speed, if the second current value is more than the second pre-set current value,
Illustrate that the cleaning effect of indoor set heat exchanger is preferable, close the automatically cleaning pattern of air conditioner, if on the contrary, the second current value is small
In the second pre-set current value, then illustrate that the cleannes of indoor set heat exchanger still without requirement is reached, then need to repeat above-mentioned institute
The automatically cleaning pattern for the air conditioner stated.
To judge the cleaning effect of indoor set heat exchanger, second predetermined current of the motor under different rotating speeds need to be set in advance
Value, especially, the second pre-set current value can increase to second by the first default intake for the intake of indoor set blower fan and preset
The current value of motor during intake under corresponding certain rotating speed.Alternatively, the second default intake can be the first default air intake
The 110% of amount, or more than 110%, that is to say, after indoor set heat exchanger automatically cleaning, the intake of indoor set blower fan is compared to clear
Intake before clean improves 10% and (because the screen pack of the air inlet of air conditioner has certain windage, filters deposited thereon
Dust can also influence intake, therefore the lifting amplitude of intake will not be too high), illustrate that heat exchanger automatically cleaning effect is fine,
Air conditioner can close automatically cleaning pattern.
Especially, before air conditioner closes automatically cleaning pattern, air conditioner also can determine whether the of the motor of indoor set blower fan
Whether two current values are more than or equal to the duration of the second pre-set current value more than the second preset time, for example, second it is default when
Between be 3 minutes, when indoor set blower fan motor the second current value be more than or equal to the second pre-set current value duration surpass
When crossing the second preset time, illustrate that the second current value of the motor of indoor set blower fan is continuously maintained in higher level, thus may be used
Knowing that the windage of motor reduces, load reduces, and further illustrates indoor set heat exchanger and is cleaned well, now, air-conditioning
