Connection line such as Fig. 1 institutes of air conditioner electric-controlled parts in air conditioner malfunction detection method first embodiment of the present invention Show, for convenience of description, part related to the present embodiment is only shown.
As shown, the air conditioner of the embodiment of the present invention is mainly for air-conditioner with fixed frequency, including indoor unit and outdoor unit with And the control line between indoor unit and outdoor unit, wherein indoor unit part includes mainly MCU and relevant load driving circuits Further include that inner blower drives such as inner blower driving circuit, compressor drive circuit, outer fan drive circuit and four-way valve-driving circuit The inner blower of dynamic circuit drives loads (not shown), these driving circuits are controlled by MCU to drive corresponding load running, Wherein these loads of compressor, outer wind turbine, four-way valve are arranged in outdoor unit, control and transport after being connected by indoor and outdoor control line Row.Air conditioner further includes current sensing means, such as the current detection module in figure, is connected on driven compressor output control line On, running current value for detecting compressor is simultaneously input in MCU, in order to reduce indoor and outdoor connecting line, current sensing means It is generally located in indoor unit, naturally it is also possible to be arranged in outdoor unit, the current detecting output line of many places one is only needed to arrive Indoor unit.Three line L (firewire), N (zero curve) and the GND (ground wire) of the power input of air conditioner room unit are linked on indoor unit And load is powered respectively by above-mentioned driving circuit, wherein the L lines of the load supplying in addition to compressor are by protecting Dangerous FUSE.
As shown in Fig. 2, the fault detection method based on above-mentioned air conditioner includes:
Step S101, the type parameter of air conditioner is obtained after air conditioner booting;
The type parameter of air conditioner is typically stored in the memory on controller of air conditioner, and type parameter represents air-conditioning The power of the size of device power, such as 35 types is 1.5 times or so of the power of 23 types.It can be from memory after air conditioner booting Read type parameter.
Step S102, according to the type parameter of air conditioner judge compressor open after whether need be delayed preset time with Obtain the running current value of compressor;
Step S103, when needing delay preset time, delay preset time is to obtain compressor after compressor unlatching Running current value;
Step S104, when need not be delayed preset time when, compressor unlatching after i.e. obtain compressor running current Value;
On the one hand, for the relatively small air conditioner of the power of certain types, such as air conditioner of 23/26/32 type, due to pressure The pipe-line system of air conditioner is unstable when contracting machine is just opened, and the pressure in pipe-line system reaches balance not yet, therefore causes The running current of compressor is also unstable, and when running current of actual compressor is small when big or even can't detect electricity in the short time Stream, and it should reflect that the pipe-line system of air conditioner is run under opposite stable case to acquire the compressor current value acquired State, it is therefore desirable to until compressor operating waits for that the pipe-line system of air conditioner stabilizes afterwards for a period of time, the fortune of compressor at this time The electric current that compressor is just obtained when row electric current is also stablized relatively just can guarantee that the current value that compressor obtains is accurate in this way. The preset time of above-mentioned waiting compressor operating is preferably 3 minutes.
And on the other hand, the air conditioner relatively large to some power, such as 50 type air conditioners, due to compressor operating electric current It is much larger, after compressor unlatching, run if it is the control line wrong in compressor and outer wind turbine, in Fig. 1 Shown, when the control line of compressor and outer wind turbine is reversed, the output line of outer wind turbine driving drives compressor operating, pressure at this time Output line of the contracting machine driving through current detection module drives outer fan operation, since the running current of compressor is much larger, and room Protective tube FUSE is passed through in the power supply of outer fan drive circuit on interior machine control panel, this is easy to cause within short time such as several seconds It burns by the way that the electric current of protective tube is excessive, or so that the overcurrent component such as relay in outer fan drive circuit is more than The electric current that is born and cause to damage.And for powerful type, the pipe-line system stabilization time of air conditioner quickly, A few minutes clock time is needed unlike the low power type of those described above.
Therefore different type of machines air conditioner in order to balance ensures compressor current again simultaneously accurately obtaining compressor current value In the case of component on unlikely excessive damage air-conditioner dash, need to determine the need for pressing again for different types Contracting machine is delayed preset time to obtain the running current value of compressor after opening.Such as 50 types, it may be unnecessary to it is delayed, Compressor obtains the running current value of compressor after opening, prevent in the case of wrong line since compressor current is excessive and It damages the component on control panel, and can be delayed a preset time such as 3 minutes for 23/26/32/35 these types, due to These type pipe-line system stabilization times are relatively long, and the compressor current obtained after a certain time is needed to be only accurately, and And even if the compressor control line of these types and outer wind turbine control line wrong, since the running current of compressor is relatively small, such as In the case that reversed, give the protective tube of outer fan drive circuit power supply that will not damage in a short time at this time, experiments have shown that this The time such as the even several days time just meeting of several hours that a little types need continuous work relatively long in wrong line protective tube Damage.
In the present embodiment, MCU is by reading current detection module to obtain the running current value of compressor, electric current here Detection module can realize that these circuits belong to the prior art and repeat no more based on the current detection circuit based on current transformer.
Step S105, when running current value is less than the first predetermined current threshold, compressor control line and outer wind turbine are determined Control line wrong.
In the present embodiment, MCU is compared to determine compressor control line and exogenous wind according to running current value and preset value Machine control line whether wrong.When specifically running current value is less than the first predetermined current threshold, compressor control line and outer is determined Air-blower control line wrong.
Since the electric current difference consumed when compressor and outer fan operation is very big, such as with big one air conditioner for, Compressor normal work when operating current up to 4A (800-900W) left and right, and outer wind turbine work normally when less than 1A (one As only tens W), therefore, therefore when the control line wrong of compressor and outer wind turbine both such as leads to reversal connection, the electricity detected Flow valuve can difference it is very big, with this may determine that control line whether wrong.Specifically when detection current value is less than the first default electricity When flowing threshold value, compressor control line and outer wind turbine control line wrong are determined.
When controlling compressor and outer wind turbine runs a preset time simultaneously, since the operating current of compressor compares exogenous wind Machine is big, so if small such as less than the first pre-set threshold value of comparison of operation current is got by 1 module of current detecting, then it can be true Compressor control line and outer wind turbine control line wrong are determined, when the first pre-set threshold value of setting is 1A, if detecting running current value It less than 1A, then can determine that the load of currently practical operation is not compressor, compressor control line and outer wind turbine control are determined with this Line wrong processed i.e. as both control line it is reversed, actually control at this time to be outer fan operation detected with this is exogenous wind electromechanics Stream.
Further, after determining compressor control line and outer wind turbine control line wrong, compressor and exogenous wind can be controlled Machine load is stopped, and shows the corresponding code of failure by the display equipment of air conditioner such as LED display, and/or logical Buzzer warning is crossed to be reminded.To prompt user's air conditioner to be in malfunction to repair, avoid using in failure Air conditioner is damaged.
The air conditioner malfunction detection method of the embodiment of the present invention is joined by obtaining the type of air conditioner after air conditioner is switched on It counts, and obtains the running current value of compressor after compressor is opened, and compressed according to the determination of the type parameter of air conditioner Whether machine is delayed preset time to obtain the running current value of compressor after opening, finally when running current value, to be less than first pre- If when current threshold, determining compressor control line and outer wind turbine control line wrong, air conditioner malfunction detection method energy of the invention For different air conditioner types, again in the case where ensureing to detect the control line wrong of compressor and outer wind turbine It prevents the high current of the compressor in wrong line to damage the component on air-conditioner dash, air conditioner work is improved with this Reliability, while can provide it is relevant prompt to remind user to repair, it is convenient for users to use.
Further, it is based on air conditioner malfunction detection method first embodiment of the present invention, is examined in air conditioner fault of the present invention In survey method second embodiment, compressed when determining that preset time after compressor is opened obtains according to the type parameter of air conditioner The running current value of machine further includes:
Preset time is determined according to the type parameter of air conditioner.
When the compressor of air conditioner is opened, for different type of machines, the time that the pipe-line system of air conditioner is stablized is not yet Together, specifically the relatively large type of compressor horsepower as time that 35 machine systems are stablized soon can stablize within 2-3 minutes, and work( The time that the relatively small type system of rate such as 23 machines are stablized generally requires 4-6 minutes slowly, i.e. the bigger type system of power is stablized Time it is shorter, therefore a corresponding preset time is determined according to the type of air conditioner, can so that air conditioner MCU in compressor The rational preset time that is delayed after unlatching determines that pipe-line system is stablized, so that the compressor current obtained is accurate, has Help accurately to judge as soon as possible compressor control line and outer wind turbine control line whether wrong.

Type 23 26 32 35
Preset time 6min 5min 4min 3min
Further, it is based on air conditioner malfunction detection method second embodiment of the present invention, is examined in air conditioner fault of the present invention In survey method 3rd embodiment, in order to further accurately determine the size of the first pre-set threshold value, work as running current value in step When less than the first predetermined current threshold, before determining compressor control line and outer wind turbine control line wrong, the event of above-mentioned air conditioner Hindering detection method further includes:
The first predetermined current threshold is determined according to the type parameter of air conditioner.
Because the compressor horsepower of the type adaptation of different air conditioners is different, thus the running current difference of compressor compared with Greatly, it such as one times of the compressor horsepower of 26 types and the air conditioner of two 50 types difference, is determined according to type parameter with this Corresponding first predetermined current threshold.The first threshold of the electric current of the compressor such as determined with 23/26/32/35 different types It is as follows:
Type 23 26 32 35 50
First pre-set threshold value 0.5A 0.8A 1.2A 1.5A 1.8A
Corresponding first predetermined current threshold is determined with this by the type parameter of above-mentioned determining air conditioner so that judgement Threshold value is more accurate, determines that the judgement of compressor control line and outer wind turbine control line wrong is more accurate with this.
Further, it is based on air conditioner malfunction detection method 3rd embodiment of the present invention, is examined in air conditioner fault of the present invention In survey method fourth embodiment, in order to further accurately determine the size of the first pre-set threshold value, work as running current value in step When less than the first predetermined current threshold, before determining compressor control line and outer wind turbine control line wrong, the event of above-mentioned air conditioner Hindering detection method further includes:

Further, it is based on air conditioner malfunction detection method 3rd embodiment of the present invention, is examined in air conditioner fault of the present invention In the 5th embodiment of survey method, in order to further accurately determine the size of the first pre-set threshold value, work as running current value in step When less than the first predetermined current threshold, before determining compressor control line and outer wind turbine control line wrong, the event of above-mentioned air conditioner Hindering detection method further includes:
Obtain the indoor environment temperature value of the type parameter and air conditioner of air conditioner;
The first predetermined current threshold is determined according to the indoor environment temperature value of the type parameter of air conditioner and air conditioner.
The indoor environment temperature value for further increasing air conditioner in the present embodiment with respect to second embodiment determines that first is pre- If current threshold, similar 3rd embodiment, the difference of indoor environment temperature is brought when will also result in air conditioner operation to compressor Different operating loads, therefore its compressor operating electric current is also different.Such as when indoor environment temperature is higher, the operation of compressor Electric current is bigger, therefore when indoor environment temperature difference, thus judge compressor running current first threshold be also required to Corresponding variation.
Specifically, can be as following according to the first predetermined current threshold that type parameter and indoor environment temperature determine Two-dimensional table:
