Above objects, features, and advantages can become apparent understandable, specific embodiments of the present invention are done in detail with reference to the accompanying drawing
Explanation.
Fig. 1 is the structural schematic diagram of air conditioner 100 provided in an embodiment of the present invention；Fig. 2 is provided in an embodiment of the present invention
The composition block diagram of air conditioner 100.As depicted in figs. 1 and 2, air conditioner 100 provided in an embodiment of the present invention include inner coil pipe 110,
Outer coil pipe 130, inner blower 120, outer blower 140, compressor 150 and controller 170, inner coil pipe 110 and outer coil pipe 130 be not
It can be respectively as evaporator and condenser under same operating condition.Under normal conditions, outer coil pipe 130, outer blower 140 and compressor
150 are assembled in outer cage body, are placed in outdoor；And inner coil pipe 110, inner blower 120 are then assembled in inner casing body, are placed in
It is indoor.Inner coil pipe 110, outer coil pipe 130, compressor 150 are by pipeline connection forming circuit for refrigerant circulation.Compressor 150,
Inner blower 120, outer blower 140 are electrically connected with controller 170, so as to controllably open, close and adjust operation ginseng
Number.
Further, air conditioner 100 further includes the speed probe 160 for detecting 120 revolving speed of inner blower.Revolution speed sensing
Device 160 is electrically connected with controller 170, and 120 revolving speed of inner blower of acquisition can be sent to controller 170 in real time, to control
The revolving speed of the monitoring inner blower 120 of device 170.In addition, inner blower 120 can be believed when operating normally to 170 feedback pulse of controller
Number.
In the present embodiment, controller 170 is arranged to: it is abnormal to judge whether the inner blower 120 occurs first；Work as institute
State inner blower 120 occur described first it is abnormal when, compressor 150 described in temporary close；The compressor 150 described in temporary close it
Afterwards, judge whether the inner blower 120 breaks down；If it is determined that the inner blower 120 breaks down, then the compressor is controlled
150 remain turned-off；If it is determined that the inner blower 120 does not break down, then controls the compressor 150 and restart.
There is the first exception in judgement, then whether first temporary close compressor 150 further determines inner blower 120
It breaks down.Make that there are first times when hidden danger with regard to out of service in discovery inner blower 120 in this way, evaporator can be prevented

120 there are failures, then reset itself 150, air conditioner 100 can restore normal operation.
Fig. 3 is the flow chart of the control method of air conditioner in the embodiment of the present invention.Referring to figure 3., this method is suitable for this
The air conditioner 100 that inventive embodiments provide.The control method of air conditioner includes:
It is abnormal to judge whether inner blower occurs first by step S100.
By taking air conditioner of the embodiment of the present invention 100 as an example, pulse signal that controller 170 is fed back according to inner blower 120 and
120 rotary speed information of inner blower that speed probe 160 is fed back, comes whether comprehensive descision inner blower 120 the first exception occurs.Specifically
, in the first preset time of controller 170 after powering, if not receiving the pulse signal or interior of the feedback of inner blower 120
It is abnormal then to determine that inner blower 120 occurs first continuously less than the first preset rotation speed for the revolving speed of blower 120.If controller 170
The revolving speed of the pulse signal and inner blower 120 that receive the feedback of inner blower 120 reaches the first preset rotation speed, then wind in determining
It is abnormal that machine 120 does not occur first.
Specifically, in order to avoid controller 170 is failed to judge or is judged by accident to what inner blower 120 was operating abnormally, first it is default when
Between be 45-60s, the first preset rotation speed be 80-150rpm.Preferably, the first preset time is 50s, and the first preset rotation speed is
100rpm.By selecting suitable parameter, be conducive to whether occur making accurate judgement extremely to inner blower 120.If set
The first preset time set is too long, causes to judge overlong time, is easy the feelings for being operating abnormally compressor 150 in inner blower 120
It was continued working under condition for a long time, it is unfavorable to compressor 150 that this is undoubtedly.But if the first preset time is too short, and is difficult to
Guarantee the accurate of judgement.If higher (such as 400rpm) that the first preset rotation speed is arranged does not allow after starting inner blower 120
Easily reach higher rotation speed, even if inner blower 120 is normal at this time, is also easy to be judged as occurring the first exception.If first is default
Revolving speed is arranged lower, then the operation exception of inner blower 120 may be failed to judge.Certainly, in the other embodiment of the present invention
In, the first preset time, the first preset rotation speed can be adjusted according to the actual situation, without being limited to the present embodiment institute
The range of offer.
Step S200, when there is the first exception in inner blower, temporary close compressor.
By taking air conditioner 100 provided in an embodiment of the present invention as an example, when controller 170 determines that the appearance first of inner blower 120 is different
Chang Shi, control compressor 150 temporarily cease operation.
Step S300 judges whether inner blower breaks down after temporary close compressor.
By taking air conditioner 100 provided in an embodiment of the present invention as an example, after temporary close compressor 150, controller 170 judges
Whether inner blower 120 breaks down.When judging that the first exception occurs in inner blower 120 in the step s 100, it is believed that be interior wind
There are the hidden danger of failure for machine 120, and step S300 is for confirming whether blower breaks down.Specifically, can be to inner blower 120
Operation conditions continue to monitor, such as feedback, speed conditions of pulse signal etc., whether to confirm inner blower 120
It breaks down.Specific mode can with judge it is similar whether inner blower 120 mode of the first exception occurs in step S100,
Adjustable relevant parameter.
Step S400, if it is determined that inner blower breaks down, then compressor remains closed for control；If it is determined that inner blower does not occur
Failure then controls compressor restarting.
By taking air conditioner 100 provided in an embodiment of the present invention as an example, controller 170 breaks down it in judgement inner blower 120
Afterwards, determined that failure exists and do not exclude substantially at this time, then compressor 150 is then kept to close.If it is determined that inner blower 120 is not
Break down, then before first it is abnormal may be caused by interim reason, it is abnormal at this time to have excluded, then controller
170 control compressors 150 restart, and normal work are restored to, to meet the needs of users.
Further, controller 170 if it is determined that inner blower 120 breaks down, then believe by the prompt for exporting 120 failure of inner blower
Breath, and it is out of service to control air conditioner 100.Output prompt information can remind user in time, for example loudspeaker is enabled (not show in figure
It sounds the alarm out).Control air conditioner 100 it is out of service can each component of effective protection air conditioner 100, such as inner blower 120
When stuck by foreign matter, closing inner blower 120 can be avoided motor and burn.After air conditioner 100 is closed, outer blower 140, inner blower
120 equal components are out of service, in this way being capable of energy saving.
Fig. 4 be an embodiment of the present invention in after temporary close compressor, judge what whether inner blower broke down
Flow chart.As shown in figure 4, step S300 can be specifically included on the basis of Fig. 3 embodiment:
Step S310 stops powering to inner blower after temporary close compressor.
By taking air conditioner 100 provided in an embodiment of the present invention as an example, controller 170 leads to after temporary close compressor 150
The corresponding switch of control is crossed to stop powering to inner blower 120.
Step S320, self-stopping technology have been powered to inner blower by powering again to inner blower after the second preset time.
By taking air conditioner 100 provided in an embodiment of the present invention as an example, self-stopping technology has been powered default by second to inner blower 120
After time, controller 170 thinks that inner blower 120 is powered by controlling corresponding switch again.Specifically, the second preset time
It can be set to 10-60s, it is preferred that the second preset time is set as 30s.Because inner blower 120 is caused the first exception occur
Reason may be some interim reasons, for example foreign temporarily blocks blower.It is waited after stopping and powering to inner blower 120
Second preset time, these external influence factors may exclude automatically.Therefore wait the second preset time later again to inner blower
120 power supplies can guarantee subsequent to the accuracy judged with the presence or absence of failure.
Step S330, inner blower again it is electric after, it is abnormal to judge whether inner blower occurs second.
By taking air conditioner 100 provided in an embodiment of the present invention as an example, controller 170 inner blower 120 again it is electric after, sentence
It is abnormal whether disconnected inner blower 120 occurs second.Specifically, inner blower 120 again it is electric in the case where, in third preset time
It is interior, if not receiving the pulse signal of the feedback of inner blower 120 or the revolving speed of inner blower 120 continuously less than the second preset rotation speed,
It is abnormal then to determine that inner blower 120 occurs second, otherwise, it is determined that inner blower 120 does not occur the second exception.Specifically, third is default
Time calculate starting point can be inner blower 120 again it is electric at the time of, be also possible to inner blower 120 it is electric later at the time of.
Optionally, third preset time is 20-100s, preferably 80s；Second preset rotation speed is 80-150rpm, preferably 100rpm.
Judge whether inner blower 120 occurs the second abnormal duration namely third preset time, it can be compared to the first preset time more
Short or longer, since compressor this period 150 is not run, so even this time is slightly long, also there is no system pressures
Excessively high risk.
Specifically, in some embodiments, it is different can to judge whether inner blower 120 occurs second with multiple periods
Often.For example, the pulse signal of the feedback of inner blower 120 is not received in the 4th preset time from inner blower 120 obtains electricity again
Or 120 revolving speed of inner blower continuously less than third preset rotation speed, then it is abnormal to determine that inner blower 120 occurs second for controller 170.If
120 feedback pulse signal of inner blower is received in the 4th preset time and revolving speed is not less than third preset rotation speed, then also needing
Further to judge: obtain the operating status of inner blower 120 after the 5th preset time again, if 120 feedback pulse of inner blower is believed
Number and revolving speed be not less than third preset rotation speed, it is abnormal just to determine that inner blower 120 does not occur second at this time.If inner blower 120 is
Non- feedback pulse signal or revolving speed are less than third preset rotation speed in five preset times, then are still determined as that inner blower 120 occurs
Second is abnormal.
Specifically, the 4th preset time can be 40-60s, the 5th preset time is 20-30s, and third preset rotation speed can be with
For 80-150rpm.Fig. 5 is the control logic schematic diagram of air conditioner in a specific embodiment of the invention.As shown in figure 5, at one
In specific embodiment, it is abnormal then the following steps are included: obtaining again from inner blower 120 to judge whether inner blower 120 occurs second
The pulse signal or 120 revolving speed of inner blower for not receiving the feedback of inner blower 120 in the 50s that electricity rises are then controlled continuously less than 100rpm
It is abnormal that device 170 processed determines that inner blower 120 occurs second.If receiving 120 feedback pulse signal of inner blower and revolving speed in 50s
Not less than 100rpm, then also needing further to judge: the operating status to inner blower 120 is obtained after 30s again, if inner blower
120 feedback pulse signals and revolving speed are not less than 100rpm, and it is abnormal just to determine that inner blower 120 does not occur second at this time.If inner blower
120 in the 5th preset time (namely period of 30s) non-feedback pulse signal or revolving speed be less than 100rpm, then still determine
It is abnormal to occur second for inner blower 120.Judged as can be seen that being divided into two periods (50s and 30s), it can be to avoid
The case where first period does not occur exception, but second period restores misoperation again.
Step S340 determines that inner blower breaks down, otherwise, it is determined that inner blower is not if the second exception occurs in inner blower
It breaks down.
By taking air conditioner 100 provided in an embodiment of the present invention as an example, after determining that the second exception occurs in inner blower 120, that is, sentence
Determine inner blower 120 to break down.Otherwise, it is determined that inner blower 120 does not break down, at this time it is considered that inner blower 120 is occurring
First is abnormal recovered later normal.After determining that blower breaks down or do not break down, controller 170 can continue
Air conditioner 100 is controlled according to above-mentioned steps S400, details are not described herein again.
Although present disclosure is as above, present invention is not limited to this.Anyone skilled in the art are not departing from this
It in the spirit and scope of invention, can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
Subject to the range of restriction.
