S8, the on off state of detection microswitch.Wherein, on off state can comprise switch closed condition and switch off state.Due in the time that switch is closed, in switch, there is switching signal, and in the time that switch disconnects, in switch, do not have switching signal, therefore can detect by the switching signal in sense switch the on off state of microswitch.
S10, whether the on off state that judgement detects meets pre-conditioned.Pre-conditioned can be that switch is that closure state or switch are off-state, like this, judge the on off state detecting whether meet pre-conditioned can be for to judge that the on off state detecting is switch closed condition, or can be for to judge that the on off state detecting is switch off state.
S12, meets pre-conditionedly if judge the on off state detecting, determines the malposition of wind deflector.And after determining the malposition of wind deflector, can control air-conditioning execution step S404, not repeat them here.
Further preferably, S10 judges whether the on off state detecting meets pre-conditioned can comprising: judge whether the on off state detecting is closure state, wherein, be closure state if judge the on off state detecting, determine the malposition of wind deflector.
For example, as shown in Figure 3, this microswitch circuit can comprise power supply, pull-up resistor R3, current-limiting resistance R4, capacitor C 2 and microswitch CN.Wherein also, power supply can be that magnitude of voltage is+power supply of 5V.Pull-up resistor R3 can, in the time that microswitch CN disconnects, be defined as high level by the voltage that detects mouthful A, in the time that microswitch CN is closed, the voltage that detects mouthful A is defined as to low level.The first end of pull-up resistor R3 is connected with power supply, and its second end is connected with a detection mouthful A, and by capacitor C 2 ground connection, capacitor C 2 is filter capacitor, and it can be for filtering.The first end of current-limiting resistance R4 is connected with a detection mouthful A, and be connected with the second end of capacitor C 2 and pull-up resistor R3 simultaneously, its second end is connected with the first end of microswitch CN, the resistance of current-limiting resistance R4 can be 510 Ω, and current-limiting resistance R4 can flow into for restriction the electric current of singlechip control chip, to prevent that the excessive single-chip microcomputer that causes of electric current from damaging because burning.The second end ground connection of microswitch CN.
Particularly, microswitch can be arranged on to the closing position of the wind deflector of indoor set in air-conditioning unit.Wherein, in the time that wind deflector is placed in closing position by people for pulling; microswitch CN can be closed; as shown in Figure 3, in the time that microswitch CN is closed, can low level be detected by detecting a mouthful A; now can carry out wind deflector safeguard measure; that is, control air-conditioning execution step S404, do not repeat them here.
Preferably, in embodiments of the present invention, in aforesaid arbitrary guard method, the position of controlling air-conditioning correction wind deflector can comprise:
S14, shuts down wind deflector execution reset processing by the load of controlling in air-conditioning.
S16, after wind deflector resets, restarts control wind deflector by control load and moves by preset state.
For example, in the time of operation of air conditioner, if wind deflector closure detected, or detect that wind deflector is not in default open mode, determine wind deflector malposition, control air-conditioning by controller (as single-chip microcomputer) simultaneously wind deflector is corrected as to normal position by out-of-the way position.Wherein, if wind deflector closure, control air-conditioning wind deflector is corrected as to open mode by closure state, particularly, wind deflector can be corrected as to default open mode by closure state, this default open mode can be the open mode of acquiescence, or it can be the running status of wind deflector before malposition, or the open mode that resets of user; If wind deflector is in open mode, and current open mode is not default open mode, controls air-conditioning wind deflector is corrected as to default open mode by current open mode.
Wherein, in embodiments of the present invention, can correct by following steps control air-conditioning the position of wind deflector: first, occur abnormal if detect the position of wind deflector on air-conditioning, can control air-conditioning load and shut down, sweep up and down the reset of wind wind deflector thereby reach control; Then,, sweeping up and down after wind wind deflector resets, can control air-conditioning load and restart, and control and sweep up and down wind wind deflector and move according to aforesaid default open mode.
It should be noted that, in embodiments of the present invention, air-conditioning load can comprise compressor, inner blower, outer blower fan and cross valve etc.Taking inner blower as example, control air-conditioning inner blower and shut down and can comprise: judging whether inner blower is stopped status, is stopped status if judge inner blower, control air-conditioning and keep inner blower to shut down; Be open state if judge inner blower, control air-conditioning after inner blower operation Preset Time, control inner blower and shut down.For example, can control inner blower shutdown after low wind operation N second.
It should be noted that, can in the computer system such as one group of computer executable instructions, carry out in the step shown in the flow chart of accompanying drawing, and, although there is shown logical order in flow process, but in some cases, can carry out shown or described step with the order being different from herein.
Obviously, those skilled in the art should be understood that, above-mentioned of the present invention each module or each step can realize with general calculation element, they can concentrate on single calculation element, or be distributed on the network that multiple calculation elements form, alternatively, they can be realized with the executable program code of calculation element, thereby, they can be stored in storage device and be carried out by calculation element, or they are made into respectively to each integrated circuit modules, or the multiple modules in them or step are made into single integrated circuit module to be realized.Like this, the present invention is not restricted to any specific hardware and software combination.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
