Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Embodiment 1
As shown in Figure 1, it is the flow chart of air conditioner intelligent Defrost method of the present invention；Wherein, the air conditioner intelligent defrosting side
Method, comprising:
Step a when operation of air conditioner heating mode, obtains the frosting state of condenser and defrosts；
Due to only having in a heating mode in air-conditioning, it just will appear the demand of defrosting；Therefore it detects in a heating mode
With obtain condenser frosting state and defrost, in order to carry out the cleared operation of subsequent frosting.
In this way, subsequent further judgement can be convenient for by the different frosting states of record/acquisition condenser.
Step b obtains indoor human body in real time and incudes number when user shuts down and the frosting state is the first preset state
According to the temperature data with the condenser；
User's shutdown, refers to that user has issued shutdown command by remote controler or other modes, so that air-conditioning enters
Off-mode, but air-conditioning is in the shutdown state, internal and not all component etc. is all in closed state, on backstage
Still there are subprogram or component operation, to guarantee to ring when user assigns other orders such as booting
It answers.In this application, it is not possible to user's shutdown be interpreted as to close or disconnect air conditioner power source.
Step c, when indoor someone is not detected within the first duration, control air-conditioning booting；
Wherein, the indoor human body sensed data in the step b can be only to judge or detect whether interior has
People；The judgement perhaps detect can be realized by force-feeling sensor 5 or by Image Acquisition, camera information acquisition or
Data processing or analysis are carried out after the Image Acquisition house data of person's infrared video camera to realize, or pass through sound sensor
Device, vibrating sensor acquire the post-processing of indoor sound perhaps vibration data to realize or by other sensors etc.
To realize.Concrete application situation can take according to the actual situation corresponding component or setting program to realize.
Wherein, first duration is set, is to judge that indoor occupant retains state: if indoor occupant is not
Have and gos out or the long period rests on that outdoor (for the room for placing air conditioner indoor unit, which may be outside the room
Other spaces or room) plan, then its residence time indoors can be long, or frequently enters and leaves that indoor (personnel are busy
When)；If personnel go out or the long period rests on outdoor, interior can can't detect indoor occupant in long time
Image, sound or vibration data etc..That is, we set first duration, if in the period
It is interior, it persistently can't detect indoor someone, it may be considered that it may be to go out or other reasons that indoor personnel, which have very big,
Rest on the outdoor some time.
In this way, we can be in the short time (the first duration) by the way that personnel are retained with state (human body sensing data)
State continued case, behavior of the personnel within the subsequent long period is predicted, consequently facilitating it is subsequently selected more suitably
Operation.
Wherein, first duration can be 20min-40min；Once interior is in 20min-40min
Unmanned state, then indoor occupant has very that maximum probability is outgoing or other behaviors, the long period can rest on outdoor, in this way interior
Air-conditioning can directly carry out related operation, influence when without considering operation to indoor occupant.
Preferably, first duration is preferably 30min；Judgement is more accurately and conveniently in this way.
Step d carries out frosting to air-conditioning according to the temperature data of the indoor human body sensed data and the condenser and removes
Net control.
In this way, by recording different defrosting states, convenient for automatic defrosting after the normal defrosting of judgement needs or shutdown；Nobody
When start the cleared control of frosting, be that the influence blown a cold wind over during defrosting is preferably minimized, and be judgement indoor a period of time
The interior no talent is switched on defrosting, in this way, relative to defrosting is carried out in user's heating operations and once interior boots up once nobody
Defrosting can only go out the small meeting in room one to avoid the influence blown a cold wind over during defrosting or user, back when room temperature reduce it is very much
Influence, given user preferably to experience；And shut down after just defrost, be user without air-conditioning heating demand when just start to remove
Frost reaches minimum to customer impact, further improves experience effect.In addition, indoors in a period of time nobody when remove
Frost can not consider the influence to defrost to indoor occupant, clean so as to remove the frosting on condenser, improve air-conditioning
Heating effect and comfort；In this way, can obviously feel that air-conditioning heating effect improves when next user reuses air-conditioning heating,
Promote user experience；When to solve use in winter (outdoor low temperature environment), the accumulative frosting of condenser for outdoor unit of air conditioner or
It freezes and removes not clean problem, promote the heating effect of air-conditioning.
Wherein, in the step a, the frosting state of condenser is divided into three kinds, respectively low frosting state, middle frosting shape
State and high frosting state (name of three kinds of states can be determines according to actual conditions), the state represented are respectively as follows:
1) when a small amount of frosting of outdoor condenser, it is denoted as state A (low frosting state), continues to run system in this case
Heat；
2) when outdoor condenser volume frosting, it is denoted as state B (middle frosting state), it is dynamic to execute defrosting in this case
Make；
3) unclean because defrosting when outdoor condenser, when accumulating a large amount of frosts or freezing, it is denoted as state C (high frosting state),
Defrosting movement is executed in this case, can specify that longest defrosting time no more than the first threshold time；
Wherein it is possible in operation of air conditioner heating mode, by judge outdoor environment temperature and/or condenser temperature and/
Or indoor environment temperature and/or indoor evaporator temperature, and by each sensor temperature independent analysis or combinatory analysis, come real-time
Detection judges the frosting state of condenser.
Following step is that the deterministic process of frosting state, as shown in connection with fig. 3, the step are carried out with temperature detection data
A includes:
Step a1 under heating mode, obtains temperature detection data T0, and preset first temperature threshold value T1, second temperature threshold
Value T2, third temperature threshold T3；
In this step, available single temperature data, in other words, the temperature detection data are outdoor environment temperature
One of degree, condenser temperature, indoor environment temperature and indoor evaporator temperature.
Two or more (two kinds, three kinds, four kinds) of above-mentioned four kinds of temperature datas can also be combined, to lead to
Temperature detection data after crossing combination are judged, are also to include at least outdoor environment temperature, condenser temperature, indoor environment
Two wherein of temperature and indoor evaporator temperature.At this point, when judging, it can be first by least two temperature before combination
Data are combined into a temperature detection data by merging the groups such as formula, such as distribute different weights, each temperature data and weight
The sum of products as temperature detection data；Temperature detection data can also be directly considered to multiple temperature numbers before combination
According to being judged respectively multiple temperature datas, temperature inspection assert when multiple temperature datas correspond with corresponding range
Measured data meets some corresponding correspondence range, and such as only ambient temperature is less than -5 DEG C, and condenser temperature is less than -3 DEG C
When just think the value range of the high frosting state of temperature detection data fit.
During specifically used, it can be selected according to the actual situation, as long as meeting the temperature detection
Data are including at least one of outdoor environment temperature, condenser temperature, indoor environment temperature and indoor evaporator temperature
?.
In addition, wherein the first temperature threshold T1, second temperature threshold value T2, third temperature threshold T3 are preset threshold value,
Actual numerical value can be determines according to actual conditions.Wherein, the first temperature threshold T1, second temperature threshold value T2, third temperature threshold
T3 is three temperature thresholds from big to small, and T1 >=T2 >=T3, unit is DEG C.
Step a2, in T2 < T0≤T1, recording the condenser is low frosting state；
Step a3, in T3 < T0≤T2, recording the condenser is middle frosting state；
Step a4, in T0≤T3, recording the condenser is high frosting state.
Above three step is according to temperature detection data T0 in different data areas, to three kinds of knots of condenser
The judgement of white state.Automatic defrosting after needing normal defrosting convenient for subsequent judgement or shut down.
Wherein, the step a further include:
Step a5, the condenser be middle frosting state or high frosting state when, control air-conditioning enter defrosting mode into
Row defrosting；
Step a6, the defrosting time of timing air-conditioning；
Step a7, after the defrosting time is more than or equal to first time threshold, control air-conditioning exits defrosting mode.
Step a5-a7 is to carry out defrosting operation to the condenser of the air-conditioning in heating mode；Condenser is in middle frosting
When state or high frosting state, illustrate that air-conditioning needs to defrost, if selecting not defrost in view of the comfort of user at this time, meeting
The serious consequence for causing heating efficiency decline and condenser to be freezed, so if judging that condenser is in middle frosting state or high knot
When white state, defrost.
Wherein, it defrosts after the defrosting operation and shutdown of the step, mutual and Lothrus apterus；The defrosting of the step,
It is the normal operation in order to guarantee air-conditioning heating mode, and starts defrosting after shutting down after a period of time, is to not influence
It is in the case where user experience, the frost of condenser is cleared, to promote the heating efficiency after booting, improve user experience.
Wherein, in the step a7, the temperature of first time threshold or condenser can also be reached in the defrosting time
When degree reaches a certain threshold value, control air-conditioning exits defrosting mode；Other control air-conditionings can also be further added by and exit defrosting mode
Qualifications, be specifically subject to actual needs.
In other words, the purpose of step a7 is to judge when air-conditioning exits defrosting condition, is directed to this feelings in the prior art
Condition usually judges condenser temperature and/or defrosting time, is strong based on air conditioner indoor unit temperature, electric current there are also judgement
The scheme that is judged of other data of degree etc., these are all in the technical solution for can be applied to the application (in this step),
As long as it may determine that when air-conditioning can exit defrosting condition.In specific application, can also according to actual needs, if
Other Rule of judgment are set to control exiting for air-conditioner defrosting mode.
In addition, if condenser add up frosting after, will lead to defrosting number it is more and more frequent, defrosting interval it is smaller and smaller,
Therefore the frosting state of condenser can more accurately be judged from the time interval between defrosting twice.
Wherein, the step a further include:
Step a8, when air-conditioning exits defrosting mode, the non-defrosting time of timing air-conditioning enters defrosting in air-conditioning next time
Stop timing when mode；
Step a9, if it is middle frosting that the non-defrosting time, which is less than second time threshold and the frosting state of the condenser,
The frosting state of the condenser is changed to high frosting state by state.
Among these, the non-defrosting time, for it is adjacent twice defrosting (air-conditioning enter defrosting mode carry out defrosting backed off after random remove
White mode) between time interval, since condenser temperature (or temperature detection data) gradually decreases, so unless pole
Atrocious weather is held, otherwise air-conditioning is most likely in the case where frequently entering middle frosting state and releasing, at this point, on condenser very
Started the accumulative of frosting in big degree, in this way, by step a8, a9, can the frosting state to condenser have and more prepare
Judgement promotes the heating efficiency of air-conditioning so as to the defrosting operation more prepared after shut down.
Wherein, as shown in connection with fig. 4, the step b includes:
Step b1, the frosting state of the condenser before obtaining user when the user turns it down and shutting down；
Wherein, the frosting state of condenser is changed at any time, one with air-conditioning defrosting in a heating mode
As in the case of, with the operation of heating mode, the temperature detection data of condenser are gradually reduced, in other words, if not
If carrying out defrosting movement, the frosting state of condenser can be middle frosting state by low frosting state change, then change
For high frosting state；After defrosting movement is added, understand when the frosting state of condenser is middle frosting state or high frosting state,
Defrosting movement is carried out, the temperature detection data of condenser can rise at this time, and the frosting state of condenser can reversely switch, by
High frosting state change is middle frosting state or middle frosting state change is low frosting state.
Wherein, the frosting state for obtaining the condenser before user shuts down, refers to that user issues power-off operation
Afterwards, the frosting state of condenser, if middle frosting state is just switched to high frosting state by condenser, then it is assumed that user's shutdown
The frosting state of the preceding condenser is high frosting state.
Step b2 obtains the indoor human body when the frosting state is low frosting state or high frosting state in real time
The temperature data of sensed data and the condenser.
If the frosting state of the condenser is low frosting state before user shuts down, on corresponding condenser
There can be a small amount of frosting, but the frosting and the requirement not up to defrost in a heating mode；In the case, by it
The case where regarding as needs shutdown defrosting is used in this way, can also be removed a small amount of frosting completely by shutdown defrosting next
Air-conditioning would be at the very high state of heating efficiency when family is switched on, to improve the experience of client.
If the frosting state of the condenser is high frosting state before user shuts down, on corresponding condenser
There can be extremely large amount of frosting even to freeze；In the case, regarded as needing to shut down defrosting the case where, in this way, can be with
By shutdown defrosting that extremely large amount of frosting or even the removing that freezes is clean, in next user booting, air-conditioning would be at heating effect
The very high state of rate, to improve the experience of client.
The indoor human body sensed data therein, can be only judge interior whether someone.
Wherein, as shown in connection with fig. 2, the step d includes:
Step d1, control air-conditioning enter defrosting mode；
Wherein, in the defrosting mode in this step, the operating condition of air-conditioning is identical as the normal defrosting mode of air-conditioning, only
One the difference is that exit the qualifications (limitation for cancelling defrosting time) of defrosting mode；It therefore, herein, can be sky
Transfer in into defrosting mode be considered now one of air-conditioned modus operandi.
In addition, since existing air-conditioning is in defrosting, in order to reduce the adverse effect to indoor occupant, generally in defrosting mode
It controls the indoor wind deflector of air-conditioning to close, inner blower is out of service；This reduces defrosting efficiencies.In order to increase to condenser
Defrosting effect；After control air-conditioning enters defrosting mode, wind deflector opening can also be controlled, inner blower, which brings into operation, (while to be taken
Disappear the limitation of defrosting time).
Step d2 judges whether the frosting of the condenser is cleared according to the temperature data of the condenser；
The temperature data of real-time detection condenser, it is described cold to judging in order to according to the temperature data of the condenser
Whether the frosting on condenser is cleared；Herein, defrost temperature threshold can be preset according to the actual situation, if the temperature of condenser
More than or equal to defrost temperature threshold, then it is assumed that the frosting of the condenser is cleared.If in order to further ensure that condenser
Frosting it is cleared, defrost temperature threshold can be more than or equal in the temperature of condenser, and after the state continues for some time, just recognize
Frosting for the condenser is cleared.
In this way, by this step, without minimum defrosting time, until outer machine frost is except clean；When next user reuses air-conditioning
When heating, it can obviously feel that air-conditioning heating effect improves, promote user experience.
Step d3, cleared or when detecting indoor someone in the frosting of the condenser, control air-conditioning exits defrosting mode
And it shuts down.
After booting defrosting, can in real-time detection room whether someone, once there is the case where indoor someone, then no matter the defrosting
Operation can all control air-conditioning at once and exit defrosting mode and shut down to which degree；Wherein, for it is indoor whether the inspection of someone
Survey, once there is the case where indoor someone, will be stopped defrosting at once, belong to disconnection mechanism always in real-time perfoming.
In addition, can also control air-conditioning if the frosting of condenser is cleared and exit defrosting mode and shut down；It is complete for air-conditioning at this time
At defrosting task.
If in this way, detect indoor someone, automatically exiting from defrosting during Auto Power On defrosting, air-conditioning shuts down,
Wait user's operation in next step (user reopens air-conditioning and heats or issue other control instructions etc.)；So as to avoid
Defrosting mode is influenced caused by indoor occupant.
In this way, in this real-time detection room whether someone.When thickizationer white on outer machine condenser be not clean, or even icing
When, and current air-conditioning is not keyed up, when detect it is indoor nobody when, automatically turn on air-conditioning and defrost, without minimum defrosting time, directly
After being removed completely to outer machine frost, then shut down.When next user reuses air-conditioning heating, it can obviously feel that air-conditioning heating effect becomes
It is good, promote user experience.
In this way, defrost for adverse circumstances or the not clean air-conditioning of defrosting, when air-conditioning is not used, the frost of accumulation or
Ice is cleared, and user can be promoted using heating effect when air-conditioning next time, improves air conditioning comfortableness；By in real-time detection room whether
Whether someone terminates defrosting movement to decide whether to defrost, and when defrosting, prevents cold wind from blowing to user, feel user
To discomfort.

The controller 1, in operation of air conditioner heating mode, to obtain the frosting state of condenser and defrost；
The force-feeling sensor 5 and the temperature sensor 6, in user's shutdown and the frosting state is first pre-
If when state, obtaining the temperature data of indoor human body sensed data and the condenser in real time；
The controller 1, also indoor someone is not detected within the first duration when, control air-conditioning booting；
And it is cleared to air-conditioning progress frosting according to the temperature data of the indoor human body sensed data and the condenser
Control.
In this way, by recording different defrosting states, convenient for automatic defrosting after the normal defrosting of judgement needs or shutdown；Nobody
When start the cleared control of frosting, be that the influence blown a cold wind over during defrosting is preferably minimized, and be judgement indoor a period of time
The interior no talent is switched on defrosting, in this way, relative to defrosting is carried out in user's heating operations and once interior boots up once nobody
Defrosting can only go out the small meeting in room one to avoid the influence blown a cold wind over during defrosting or user, back when room temperature reduce it is very much
Influence, given user preferably to experience；And shut down after just defrost, be user without air-conditioning heating demand when just start to remove
Frost reaches minimum to customer impact, further improves experience effect.In addition, indoors in a period of time nobody when remove
Frost can not consider the influence to defrost to indoor occupant, clean so as to remove the frosting on condenser, improve air-conditioning
Heating effect and comfort；In this way, can obviously feel that air-conditioning heating effect improves when next user reuses air-conditioning heating,
Promote user experience；When to solve use in winter (outdoor low temperature environment), the accumulative frosting of condenser for outdoor unit of air conditioner or
It freezes and removes not clean problem, promote the heating effect of air-conditioning.
Embodiment 3
