Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of indicating fault method, and for refrigerator, described refrigerator comprises at least one electric elements, and as shown in Figure 1, described indicating fault method comprises:
Step 101, detect described refrigerator and whether break down.
In the use procedure of refrigerator, may produce various fault due to improper use or such environmental effects, common fault comprises mechanical breakdown and electric elements fault.Under normal circumstances, the electric elements of refrigerator are more, and when refrigerator breaks down, these electric elements break down often.The electric elements that refrigerator comprises can be divided into two classes, and a class is the electric elements of input type, for the control panel input signal to refrigerator, such as potentiometer, refrigerator temperature sensor, freezer temperature sensor, evaporator temperature sensor, the door switch of refrigerating chamber and the door switch of refrigerating chamber; Another kind of is the electric elements of output type, for receiving the control signal of control panel, and adjusts according to described control signal, the freezing blower fan of such as Defrost heater, band speed feedback and refrigerating chamber illuminating lamp.Because each electric elements are connected with control panel, therefore when electric elements break down, control panel can detect it is that fault has appearred in which electric elements.
Step 102, when described refrigerator breaks down, determine the fault type of described fault.
Common, the corresponding relation of fault and fault type can be prestored in refrigerator, when refrigerator breaks down time, according to described corresponding relation, the fault type of this fault can be determined.Example, suppose that the potentiometer of refrigerator breaks down, corresponding fault type can be potentiometer fault; Suppose that evaporator temperature sensor breaks down, corresponding fault type can be evaporation sensing fault.In practical application, fault type can also refinement more, example, suppose that potentiometer breaks down, control panel can judge it is that the knob of potentiometer breaks down, corresponding fault type can be potentiometer knob fault, and other fault types that potentiometer is corresponding can also have potentiometer mechanical breakdown to be connected fault etc. with potentiometer; Suppose that evaporator temperature sensor breaks down, control panel can judge it is that the probe of evaporator temperature sensor breaks down, corresponding fault type can be evaporation sensing probe fault, and other fault types that evaporator temperature sensor is corresponding can also have evaporation sensing to connect fault and evaporation sensing power failure etc.
Step 103, indicate the corresponding relation of type according to fault type and illuminating lamp, control at least one room illumination lamp that described refrigerator comprises and indicate type to indicate according to the illuminating lamp corresponding with described fault type.
Common, refrigerator comprises multiple rooms, each room may be provided with a room illumination lamp, example, refrigerator can comprise multiple refrigerator room, each refrigerator room is provided with a room illumination lamp, when carrying out fault type instruction, can indicate by room illumination lamp between one of them refrigerator room according to the illuminating lamp instruction type that described fault type is corresponding; Also can room illumination lamp be by all indicating according to the illuminating lamp instruction type that described fault type is corresponding between multiple refrigerator room, the embodiment of the present invention does not limit this.
Common, can prestore in refrigerator fault type and illuminating lamp indicates the corresponding relation of type, suppose the flashing times indication fault type by illuminating lamp, namely this fault type and illuminating lamp indicate the corresponding relation of type to represent the corresponding different illuminating lamp flashing times of different fault types.After the fault type determining to break down, illuminating lamp flashing times corresponding to described fault type can be obtained according to this corresponding relation, then at least one room illumination lamp indicating refrigerator to comprise glimmers according to this illuminating lamp flashing times, under normal circumstances, described room can be refrigerating chamber, refrigerating chamber or fresh-keeping chamber etc., the embodiment of the present invention does not limit this.
Example, indicating fault can be carried out by the illuminating lamp of refrigerating chamber, assumed fault type and illuminating lamp indicate the illuminating lamp that in the corresponding relation of type, potentiometer fault is corresponding to indicate type to be flicker 2 times, when the potentiometer of refrigerator breaks down, refrigerator can indicate the illuminating lamp flicker twice of refrigerating chamber, and the potentiometer being used for warning user's refrigerator breaks down.
In practical application, also different fault types can be indicated by the different colours of illuminating lamp, such as assumed fault type and illuminating lamp indicate the illuminating lamp that in the corresponding relation of type, potentiometer fault is corresponding to indicate type to be ruddiness, then when the potentiometer of refrigerator breaks down, refrigerator can indicate the illuminating lamp of refrigerating chamber to send ruddiness, and the potentiometer being used for warning user's refrigerator breaks down.Or the different order also can lighted by room illumination lamp between difference indicates different fault types, such as, suppose that refrigerator comprises room between three, be respectively refrigerating chamber, refrigerating chamber and fresh-keeping chamber, each room is provided with a room illumination lamp, assumed fault type indicates the illuminating lamp that in the corresponding relation of type, potentiometer fault is corresponding to indicate type to be according to refrigerating chamber with illuminating lamp simultaneously, the order of refrigerating chamber and fresh-keeping chamber is lighted successively, then when the potentiometer of refrigerator breaks down, control panel can indicate refrigerating chamber, the illuminating lamp of refrigerating chamber and fresh-keeping chamber is lighted successively, the potentiometer being used for warning user's refrigerator breaks down.
So, the embodiment of the present invention, when carrying out indicating fault, does not need to arrange special failure indication module, but indicated by refrigerator at least one room illumination lamp existing, save material, reduced the cost of refrigerator, be conducive to promoting the use of of refrigerator.Meanwhile, because the electric elements controlling room illumination lamp between refrigerator are less, when making to carry out indicating fault by a room illumination lamp, the possibility affecting the accuracy of indicating fault because a room illumination lamp breaks down is less, improves the accuracy of indicating fault.
Optionally, if electric elements fault appears in refrigerator, according to the corresponding relation of electric elements and fault type, the fault type of fault can be determined.
Example, the corresponding relation of electric elements and fault type can be as shown in table 1.
First of table 1 electric elements and fault type is correspondingly shown
| Electric elements | Fault type |
| Potentiometer | Potentiometer fault |
| Refrigerator temperature sensor | Refrigeration sensing fault |
| Freezer temperature sensor | Freezing sensing fault |
| Defrost heater | Heater failure |
| Blower fan | Fan trouble |
Control panel can determine fault type according to table 1 after detecting that a certain electric elements break down.Needs illustrate, the embodiment of the present invention is described for table 1, does not limit name and the quantity of fault type.
Optionally, if there is electric elements fault in refrigerator, suppose that the electric elements broken down are fault electric elements, also the position of breaking down in fault electric elements can first be determined, then according to electric elements, the corresponding relation of location of fault and fault type, determines the fault type of described fault.
Example, the corresponding relation of electric elements and fault type can be as shown in table 2.
Second of table 2 electric elements and fault type is correspondingly shown
After control panel detects that a certain electric elements break down, first can determine the position that fault occurs, then can determine fault type according to table 2.Need to illustrate, the embodiment of the present invention is described for table 2, does not limit the position that electric elements break down, and the name of fault type and quantity.
Further, at the described corresponding relation indicating type according to fault type and illuminating lamp, controlling at least one room illumination lamp that described refrigerator comprises indicates before type indicates according to the illuminating lamp corresponding with described fault type, first can also judge whether the door switch of the refrigerator compartment that at least one room illumination lamp described is corresponding is in closed condition, when the door switch of refrigerator compartment corresponding at least one room illumination lamp described is in closed condition, the corresponding relation of type is indicated according to fault type and illuminating lamp, controlling at least one room illumination lamp described indicates type to indicate according to the illuminating lamp corresponding with described fault type.
Due in the normal use procedure of refrigerator, a room illumination lamp plays illuminating effect, if so break down once at refrigerator, a room illumination lamp just starts to carry out glimmering, and can affect the normal use of refrigerator.Therefore in practical application, the door switch of refrigerator compartment can be adopted as indicating fault switch, when for carry out room illumination lamp between indicating fault corresponding between the door switch of room be in closed condition time, represent that this time room illumination lamp does not now need to throw light on, namely may be used for indicating fault, when for carry out room illumination lamp between indicating fault corresponding between the door switch of room be in opening time, represent that this time room illumination lamp is for illumination.In practical application, indicating fault switch also can be the switch arranged separately, also can for and to the combination of the multiple switches comprised, the embodiment of the present invention does not limit this, the embodiment of the present invention is described for the door switch of refrigerating chamber, such as, when detecting that the door switch of refrigerating chamber is opened, represent that the current refrigerating chamber illuminating lamp that needs throws light on, then normally light this illuminating lamp, when detecting that the door switch of refrigerating chamber is closed, represent that the current refrigerating chamber illuminating lamp that needs carries out indicating fault, the corresponding relation of type now can be indicated according to fault type and illuminating lamp, controlling described refrigerating chamber illuminating lamp indicates type to indicate according to the illuminating lamp corresponding with described fault type.
It should be noted that, the door switch of the refrigerating chamber described in the embodiment of the present invention is closed and is not referred to that refrigerating-chamber door is really closed, and refer to that the door switch of refrigerating chamber is in closed condition, when refrigerating-chamber door is opened, maintenance personal also can manually make door switch be in closed condition, do not affect the normal use of user like this, be convenient to make maintenance personal understand fault type simultaneously yet, keep in repair.
Further, at the described corresponding relation indicating type according to fault type and illuminating lamp, controlling at least one room illumination lamp that described refrigerator comprises indicates before type indicates according to the illuminating lamp corresponding with described fault type, can also first judge described refrigerator power on after continuous firing duration whether be less than or equal to preset duration, when after described refrigerator powers on, continuous firing duration is less than or equal to described preset duration, the corresponding relation of type is indicated according to fault type and illuminating lamp, controlling at least one room illumination lamp that described refrigerator comprises indicates type to indicate according to the illuminating lamp corresponding with described fault type.
In actual applications, when refrigerator breaks down, if illuminating lamp continues indication fault type, the normal use of user may being affected, therefore can only indicating when needing repairing.Usual maintenance personal is when keeping in repair refrigerator, need first to initialize refrigerator, namely re-power after giving refrigerator power-off, therefore can first judge refrigerator power on after continuous firing duration whether be less than or equal to preset duration, described preset duration pre-sets, usually 10 minutes can be set to, namely in 10 minutes after refrigerator powers on, refrigerator can indicate the corresponding relation of type according to fault type and illuminating lamp, control at least one room illumination lamp to indicate according to the illuminating lamp corresponding with fault type instruction type, after 10 minutes, between room illumination lamp only carry out normal illumination work, do not carry out indicating fault, be convenient to economize on resources, do not affect Consumer's Experience simultaneously.
Further, at the described corresponding relation indicating type according to fault type and illuminating lamp, controlling at least one room illumination lamp that described refrigerator comprises indicates before type indicates according to the illuminating lamp corresponding with described fault type, first can also judge that described refrigerator indicates the number of times of described fault type whether to be less than or equal to preset times, when described refrigerator indicates the number of times of described fault type to be less than or equal to described preset times, the corresponding relation of type is indicated according to fault type and illuminating lamp, controlling at least one room illumination lamp that described refrigerator comprises indicates type to indicate according to the illuminating lamp corresponding with described fault type, when described refrigerator indicates the number of times of described fault type to be greater than described preset times, control at least one room illumination lamp described and normally light or extinguish.
Example, suppose the flashing times indication fault type adopting refrigerating chamber illuminating lamp, if after refrigerator breaks down, refrigerating chamber illuminating lamp continues flicker, the fault that continuous print instruction refrigerator occurs, then can affect the normal use of user, therefore preset times can be set to indicating fault, each illuminating lamp only needs to indicate preset times fault type continuously, then when refrigerator indicates the number of times of described fault type to reach described preset times, the door of user's closing cold room, then illuminating lamp normally extinguishes, user opens the door of refrigerating chamber, then illuminating lamp is normally lighted, the fault that user's refrigerator occurs can be pointed out so in time, do not affect the normal use of user simultaneously yet.Meanwhile, for the ease of distinguish, with once instruction in, there is the first prefixed time interval between adjacent twice flicker, between adjacent twice flicker, the second prefixed time interval can be there is, the first prefixed time interval and the second prefixed time interval unequal.
Such as, suppose that the potentiometer of refrigerator breaks down, namely fault type is potentiometer fault, the refrigerating chamber illuminating lamp flashing times corresponding with potentiometer fault is twice, first prefixed time interval is 0.5s, and the second prefixed time interval is 5s, then during refrigerator appearance potential device fault, when user opens the door of refrigerating chamber, the illuminating lamp of refrigerating chamber starts flicker continuously twice, and interval 0.5s between twice flicker, after 5s, again glimmer twice continuously, then indicating fault is complete.Now, if the door of user's closing cold room, then refrigerating chamber illuminating lamp extinguishes, and economizes on resources; If user opens the door of refrigerating chamber, then refrigerating chamber illumination lamp ignition, is convenient to user and normally uses refrigerator.
Preferably, described fault type and illuminating lamp indicate the corresponding relation of type can be the different corresponding different illuminating lamp flashing times of fault type, the corresponding relation of type is being indicated according to fault type and illuminating lamp, control at least one room illumination lamp that described refrigerator comprises when indicating type to indicate according to the illuminating lamp corresponding with described fault type, illuminating lamp flashing times that can be corresponding according to described fault type, indicates room illumination lamp between described refrigerator to glimmer.In practical application, can there is the first prefixed time interval between adjacent twice, this first prefixed time interval can set as the case may be, and the embodiment of the present invention does not limit this.
In practical application, also the situation simultaneously occurring various faults may be there is, fault type the sorting from high to low according to priority that therefore can will may occur in advance, when there is multiple fault type, can according to priority orders indication fault type, limit the quantity between two kinds of fault type instructions and there is the 3rd prefixed time interval, described 3rd prefixed time interval is arrange as the case may be in practical application, and the embodiment of the present invention does not limit this.
The embodiment of the present invention provides a kind of indicating fault method, first detect refrigerator whether to break down, when described refrigerator breaks down, determine the fault type of described fault, then indicate the corresponding relation of type according to fault type and illuminating lamp, control at least one room illumination lamp that described refrigerator comprises and indicate type to indicate according to the illuminating lamp corresponding with described fault type.Compared to prior art, the embodiment of the present invention, when carrying out indicating fault, does not need to arrange special failure indication module, but indicated by refrigerator at least one room illumination lamp existing, save material, reduced the cost of refrigerator, be conducive to promoting the use of of refrigerator.Meanwhile, because the electric elements controlling room illumination lamp between refrigerator are less, when making to carry out indicating fault by a room illumination lamp, the possibility affecting the accuracy of indicating fault because a room illumination lamp breaks down is less, improves the accuracy of indicating fault.
The embodiment of the present invention provides a kind of indicating fault method, as shown in Figure 2, for refrigerator, suppose in the embodiment of the present invention that electric elements fault appears in refrigerator, and refrigerator comprises three electric elements, be respectively potentiometer, refrigerator temperature sensor and blower fan, the priority order from high to low of three electric elements is blower fan, refrigerator temperature sensor, potentiometer, the embodiment of the present invention, using the door switch of refrigerating chamber as indicating fault switch, is described to adopt the different flashing times of refrigerating chamber illuminating lamp to carry out indicating fault simultaneously.
Whether step 201, detection refrigerator break down, and when refrigerator breaks down, perform step 202; When refrigerator does not break down, perform step 209.
First power on to refrigerator, then can whether all normally work by all electric elements of cycle detection while refrigerator carries out normal work, in the embodiment of the present invention, refrigerator cycle detection potentiometer, whether refrigerator temperature sensor and blower fan all normally work, after namely cycle detection completes and detects for one time, again restart to detect, also can detect according to the priority orders of electric elements in practical application, the embodiment of the present invention does not limit this, wherein fault electric elements can be potentiometer, any one in refrigerator temperature sensor and blower fan, the embodiment of the present invention for fault electric elements for blower fan is described.
Step 202, corresponding relation according to electric elements and fault type, determine the fault type of described fault, performs step 203.
Example, prestore the corresponding table of electric elements and fault type in refrigerator, as shown in table 3.
The 3rd of table 3 electric elements and fault type is correspondingly shown
| Electric elements | Fault type |
| Potentiometer | Potentiometer fault |
| Refrigerator temperature sensor | Refrigeration sensing fault |
| Blower fan | Fan trouble |
Because embodiment of the present invention assumed fault electric elements are blower fan, can determine that the fault type of refrigerator is fan trouble, also can according to the particular location broken down in blower fan in practical application, fan trouble is subdivided into different fault types, and the embodiment of the present invention does not repeat at this.Whether often kind of corresponding fault flag of fault type, there is corresponding fault type for marking refrigerator.Example, when blower fan breaks down, corresponding fault type is fan trouble, and fault flag corresponding for fan trouble is set to effectively by control panel, represents that fan trouble has appearred in refrigerator.
Whether step 203, the door switch of refrigerating chamber detecting described refrigerator are in closed condition; When the door switch of the refrigerating chamber of described refrigerator is in closed condition, perform step 204; When the door switch of the refrigerating chamber of described refrigerator is in opening, perform step 209.
After determining that fan trouble appears in refrigerator, need to carry out indicating fault for the ease of maintenance.If but refrigerating chamber illuminating lamp is after there is fan trouble in refrigerator, namely start continuously non-stoply to carry out indicating fault, then can cause the waste of electric energy, affect the normal use of user simultaneously, therefore can only indicate when maintenance personal's startup separator indicator cock, in practical application, the door switch of a room can be adopted as indicating fault switch, using the door switch of refrigerating chamber as indicating fault switch in the embodiment of the present invention, when the door switch of described refrigerating chamber is closed, represent that now user uses refrigerator, therefore illuminating lamp is normally lighted; When the door switch of described refrigerating chamber is closed, represent that now user does not need refrigerating chamber illuminating lamp to throw light on, and therefore can carry out indicating fault.
Needs illustrate, the door switch of the refrigerating chamber described in the embodiment of the present invention is closed and is not referred to that refrigerating-chamber door is really closed, and refer to that the door switch of refrigerating chamber is in closed condition, when refrigerating-chamber door is opened, maintenance personal also can manually make the door switch of refrigerating chamber be in closed condition, do not affect the normal use of user like this, be convenient to make maintenance personal understand fault type simultaneously yet, keep in repair.Certainly, when the door of refrigerating chamber is closed, refrigerating-chamber door switch is in closed condition equally, also can carry out indicating fault.
Step 204, detect after this powers on, whether the continuous firing duration of described refrigerator is less than or equal to preset duration; When the continuous firing duration of described refrigerator is less than or equal to preset duration, perform step 205; When the continuous firing duration of described refrigerator is more than or equal to preset duration, perform step 209.
In actual applications, only when maintenance personal needs the fault type understanding refrigerator, refrigerating chamber illuminating lamp is just needed to carry out indicating fault, break down when refrigerator but also do not carry out in this process of keeping in repair, indicating fault can not be carried out, therefore, before carrying out indicating fault, can also judge whether that needs indicate.Because maintenance personal is when keeping in repair refrigerator, usually need to initialize refrigerator, namely re-power after giving refrigerator power-off, so fault indication function can be realized in the short period after refrigerator powers on, so before carrying out indicating fault, can first judge refrigerator power on after continuous firing duration whether be less than or equal to preset duration, described preset duration pre-sets as the case may be in practical application, usually 10 minutes can be set to, namely in 10 minutes after refrigerator powers on, first refrigerating chamber illuminating lamp can obtain the information of fault flag, judge which Reflector bit representation is effective, then the fault type of refrigerator is obtained, and then carry out the instruction of fault type, after 10 minutes, refrigerating chamber illuminating lamp only carries out normal illumination work, do not carry out indicating fault, be convenient to economize on resources, do not affect Consumer's Experience simultaneously.
Step 205, detect described refrigerator this indicate the number of times of described fault type whether to be less than or equal to preset times; When this of described refrigerator indicates the number of times of described fault type to be less than or equal to preset times, perform step 206; When this of described refrigerator indicates the number of times of described fault type to be greater than preset times, perform step 209.
Concrete, in preset duration after refrigerator powers on, and refrigerating-chamber door switch is when being in closed condition, if refrigerating chamber illuminating lamp is always continual carry out indicating fault, then can cause the unnecessary waste of power resource, frequent flicker repeatedly simultaneously also can cause damage to refrigerating chamber illuminating lamp, therefore the preset times of indicating fault can be pre-set, when the number of times of indicating fault reaches preset times, refrigerating chamber illuminating lamp can normally extinguish or normal illumination, while achieving indicating fault, save resource.For the ease of distinguishing, between adjacent twice instruction, the second prefixed time interval can be there is.
Example, suppose that preset times is 2 times, then when fan trouble appears in refrigerator, twice fan trouble can be indicated, also may occur in practical application that the situation of various faults appears in refrigerator, suppose that fan trouble and potentiometer fault have appearred in refrigerator simultaneously, because the priority of blower fan is higher than the priority of potentiometer, therefore when indicating fault, can indicate according to priority orders, the 3rd prefixed time interval is there is between two indicating fault, namely first fan trouble is indicated, indicating potential device fault after 3rd prefixed time interval, again fan trouble is indicated after second prefixed time interval, indicating potential device fault after 3rd prefixed time interval, now complete twice indicating fault, each indicating fault comprises the instruction of two fault types.
Step 206, corresponding relation according to fault type and illuminating lamp flashing times, determine the illuminating lamp flashing times that described fault type is corresponding, performs step 207.
Example, can indicate different fault types by the difference of illuminating lamp flashing times, there is prefixed time interval between adjacent twice flicker, in the embodiment of the present invention, prefixed time interval can be 0.5s (second).Common, the corresponding table of fault type and illuminating lamp flashing times can be prestored in refrigerator, as shown in table 4,
The corresponding table of table 4 fault type and illuminating lamp flashing times
| Fault type | Illuminating lamp flashing times |
| Potentiometer fault | Glimmer 2 times |
| Refrigeration sensing fault | Glimmer 4 times |
| Fan trouble | Glimmer 6 times |
Because fan trouble has appearred in refrigerator, therefore when refrigerating chamber illuminating lamp carries out indicating fault at every turn, instruction fan trouble needs flicker 6 times.
Step 207, indicate described illuminating lamp to glimmer described in illuminating lamp flashing times, perform step 208.
When determining that fan trouble needs flicker 6 times, when needs carry out indicating fault, refrigerating chamber illuminating lamp can be made 6 times to glimmer continuously, 0.5s of being separated by between adjacent twice flicker, can complete the instruction of fan trouble.Example, the process that the illuminating lamp of refrigerating chamber carries out indicating fault is glimmer 6 times, and 0.5s of being separated by between adjacent twice flicker, has then extinguished this indicating fault.
Suppose in practical application, there is fan trouble and potentiometer fault in refrigerator, there is the time interval of 2s between adjacent two indicating fault, then the illuminating lamp of refrigerating chamber carries out the process of indicating fault is first glimmer 6 times, to be separated by between adjacent twice flicker 0.5s, then extinguish 2s, then glimmer 2 times, 0.5s of being separated by between adjacent twice flicker, then extinguish, this indicating fault can be completed.
The number of times of step 208, indicating fault adds 1, performs step 205.
Often complete primary fault instruction, indicating fault number of times can be added 1, and then whether failure judgement instruction number of times is less than or equal to preset times, when indicating fault number of times is less than or equal to preset times, repeat said process, carry out indicating fault again, if the number of stoppages is greater than preset times, then refrigerator can normally work.
Example, the preset times of assumed fault instruction is 2 times, the time interval of 5s is there is between adjacent twice indicating fault, then the illuminating lamp of refrigerating chamber carries out the process of indicating fault and is, first glimmer 6 times, to be separated by between adjacent twice flicker 0.5s, then 5s is extinguished, indicating fault number of times adds 1, then whether failure judgement instruction number of times is less than or equal to 2 times, when indicating fault number of times is less than or equal to 2 times, then glimmers 6 times, to be separated by between adjacent twice flicker 0.5s, the malfunction coefficient of preset times can be completed.
Suppose in practical application, there is fan trouble and potentiometer fault in refrigerator, the time interval of 2s is there is between adjacent two indicating fault, the preset times of indicating fault is 2 times, the time interval of 5s is there is between adjacent twice indicating fault, then the illuminating lamp of refrigerating chamber carries out the process of indicating fault and is, first glimmer 6 times, to be separated by between adjacent twice flicker 0.5s, then 2s is extinguished, then glimmer 2 times, to be separated by between adjacent twice flicker 0.5s, then 5s is extinguished, indicating fault number of times adds 1, then whether failure judgement instruction number of times is less than or equal to 2 times, when indicating fault number of times is less than or equal to 2 times, then glimmer 6 times, to be separated by between adjacent twice flicker 0.5s, then 2s is extinguished, then glimmer 2 times, to be separated by between adjacent twice flicker 0.5s, the indicating fault of preset times can be completed.
Step 209, normally to work.
When refrigerator does not break down, or the refrigerating-chamber door switch of refrigerator is in opening, or the continuous firing duration of refrigerator is less than or equal to preset duration, or when indicating fault number of times is greater than preset times, refrigerator can normally work.
It should be noted that; the sequencing of the step of the indicating fault method that the embodiment of the present invention provides can suitably adjust; step also according to circumstances can carry out corresponding increase and decrease; such as step 203, step 204; step 205 can be omitted; or step 203, step 204; the tandem of step 205 can adjust; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the method changed can be expected easily; all should be encompassed within protection scope of the present invention, therefore repeat no more.
