When the door switch for the compartment answered is closed, represent this time room illumination lamp need not now be illuminated, you can with
In indicating fault, when being in opening for carrying out the door switch of the corresponding compartment of room illumination lamp between indicating fault, table
Show that this time room illumination lamp is used to illuminate.In practical application, indicating fault switch can also be a switch being separately provided,
Can be and to including multiple switch combination, the embodiment of the present invention do not limited this, and the embodiment of the present invention is with refrigerating chamber
Door switch exemplified by illustrate, for example, when detect refrigerating chamber door switch open when, expression be currently needed for refrigerating chamber illumination
Lamp is illuminated, then normally lights the illuminating lamp, and when the door switch for detecting refrigerating chamber is closed, expression is currently needed for refrigerating chamber
Illuminating lamp carries out indicating fault, and the corresponding relation of type can be now indicated according to fault type and illuminating lamp, is controlled described cold
Hide room illumination lamp and indicate that type is indicated according to illuminating lamp corresponding with the 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 implied that refrigerating-chamber door is genuine
Close, and refer to that the door switch of refrigerating chamber is closed, in the case where refrigerating-chamber door is opened, maintenance personal can also hand
It is dynamic to be closed door switch, do not influence so the normal of user to use, while also allowing for making maintenance personal understand failure
Type, is repaired.
Further, in the corresponding relation that type is indicated according to fault type and illuminating lamp, the refrigerator bag is controlled
Before at least one room illumination lamp included indicates that type is indicated according to illuminating lamp corresponding with the fault type, may be used also
To first determine whether that whether continuous firing duration is less than or equal to preset duration after electricity on the refrigerator, holds when after electricity on the refrigerator
When continuous operating time is less than or equal to the preset duration, the corresponding relation of type, control are indicated according to fault type and illuminating lamp
At least one room illumination lamp that making the refrigerator includes indicates that type is carried out according to illuminating lamp corresponding with the fault type
Indicate.
In actual applications, when refrigerator breaks down, if illuminating lamp persistently indicates fault type, it may influence to use
The normal of family is used, therefore only can be indicated when needing repairing.Usual maintenance personal needs when being repaired to refrigerator
Refrigerator is initialized first, i.e., to being re-powered after refrigerator power-off, therefore can first determine whether on refrigerator continuous firing after electricity
Whether duration is less than or equal to preset duration, and the preset duration pre-sets, generally could be arranged to 10 minutes, that is, exist
In 10 minutes on refrigerator after electricity, refrigerator can indicate the corresponding relation of type according to fault type and illuminating lamp, and control is extremely
Room illumination lamp indicates that type is indicated according to illuminating lamp corresponding with fault type between few one, after 10 minutes,
Room illumination lamp only carries out normally illuminating work, without indicating fault, is easy to economize on resources, while not influenceing Consumer's Experience.
Further, in the corresponding relation that type is indicated according to fault type and illuminating lamp, the refrigerator bag is controlled
Before at least one room illumination lamp included indicates that type is indicated according to illuminating lamp corresponding with the fault type, may be used also
To first determine whether that the refrigerator indicates whether the number of times of the fault type is less than or equal to preset times, when the refrigerator is indicated
When the number of times of the fault type is less than or equal to the preset times, the corresponding of type is indicated with illuminating lamp according to fault type
Relation, controls at least one room illumination lamp that the refrigerator includes to indicate class according to illuminating lamp corresponding with the fault type
Type is indicated；When the refrigerator indicates that the number of times of the fault type is more than the preset times, at least one described in control
Room illumination lamp normal point is bright between individual or extinguishes.
Example, it is assumed that indicate fault type using the flashing times of refrigeration room illumination lamp, if broken down in refrigerator
Afterwards, refrigeration room illumination lamp is persistently flashed, continuous to indicate the failure that refrigerator occurs, then the normal of user can be influenceed to use, because
This can set preset times to indicating fault, and each illuminating lamp only needs continuously to indicate preset times fault type, then works as ice
When case indicates that the number of times of the fault type reaches the preset times, user closes the door of refrigerating chamber, then illuminating lamp normally puts out
Go out, user opens the door of refrigerating chamber, then illuminating lamp is normally lighted, the failure that can so point out user's refrigerator to occur in time, together
When nor affect on the normal of user and use.Meanwhile, for the ease of distinguishing, in once indicating, exist between adjacent flicker twice
First prefixed time interval, may have the second prefixed time interval between adjacent twice of flicker, the first prefixed time interval with
Second prefixed time interval is unequal.
For example, it is assumed that the potentiometer of refrigerator breaks down, i.e., fault type is potentiometer failure, corresponding with potentiometer failure
Refrigeration room illumination lamp flashing times for twice, the first prefixed time interval is 0.5s, and the second prefixed time interval is 5s, then ice
During case appearance potential device failure, when user opens the door of refrigerating chamber, the illuminating lamp of refrigerating chamber starts continuous flicker twice, dodged twice
It is spaced between bright after 0.5s, 5s, twice, then indicating fault is finished for continuous flicker again.Now, if user closes refrigerating chamber
Door, then refrigerate room illumination lamp extinguish, economize on resources；If the door of user's unlatching refrigerating chamber, refrigerating chamber illumination lamp ignition, just
Refrigerator is normally used in user.
Preferably, the fault type indicates that the corresponding relation of type can be that different fault types is corresponding from illuminating lamp
Different illuminating lamp flashing times, the corresponding relation of type is being indicated according to fault type and illuminating lamp, the refrigerator bag is controlled
When at least one room illumination lamp included indicates that type is indicated according to illuminating lamp corresponding with the fault type, Ke Yigen
According to the corresponding illuminating lamp flashing times of the fault type, room illumination lamp is flashed between indicating the refrigerator.Practical application
In, it is adjacent twice between there may be the first prefixed time interval, first prefixed time interval can enter as the case may be
Row setting, the embodiment of the present invention is not limited this.
In practical application, it is also possible to occur the situation of various faults occur simultaneously, therefore will likely can occur in advance
Fault type being ranked up from high to low according to priority, when occur multiple fault types when, can be suitable according to priority
Sequence indicates that fault type, two kinds of fault types of limitation have the 3rd prefixed time interval, the 3rd preset time between indicating
At intervals of what is set as the case may be in practical application, the embodiment of the present invention is not limited this.
The embodiment of the present invention provides a kind of indicating fault method, detects whether refrigerator breaks down first, when the refrigerator
During failure, the fault type of the failure is determined, the corresponding relation of type is then indicated according to fault type and illuminating lamp,
At least one room illumination lamp that the refrigerator includes is controlled to indicate that type is entered according to illuminating lamp corresponding with the fault type
Row is indicated.Compared to prior art, the embodiment of the present invention is when carrying out indicating fault, it is not necessary to set special indicating fault mould
Block, but indicated by least one existing room illumination lamp of refrigerator, material has been saved, the cost of refrigerator is reduced,
Be conducive to promoting the use of for refrigerator.Simultaneously as the electric elements of room illumination lamp are less between control refrigerator so that pass through compartment
When illuminating lamp carries out indicating fault, because room illumination lamp breaks down and influence the possibility of the accuracy of indicating fault compared with
It is small, improve the accuracy of indicating fault.
The embodiment of the present invention provides a kind of indicating fault method, as shown in Fig. 2 being used for false in refrigerator, the embodiment of the present invention
If electric elements failure occurs in refrigerator, and refrigerator includes three electric elements, respectively potentiometer, refrigerator temperature sensor
And blower fan, the order of the priority of three electric elements from high to low is blower fan, refrigerator temperature sensor, potentiometer, this hair
Bright embodiment is switched using the door switch of refrigerating chamber as indicating fault, while with using the different flashing times for refrigerating room illumination lamp
Illustrated exemplified by indicating fault.
Whether step 201, detection refrigerator break down, and when refrigerator breaks down, perform step 202；When refrigerator does not go out
During existing failure, step 209 is performed.
First to electric on refrigerator, then can be with all electric elements of cycle detection while refrigerator carries out normal work
In no equal normal work, the embodiment of the present invention, refrigerator cycle detection potentiometer, just whether refrigerator temperature sensor and blower fan
Often work, cycle detection is after completing a detection, to restart detection again, can also be according to electrical equipment member in practical application
The priority orders of part are detected that the embodiment of the present invention is not limited this, and wherein failure electric elements can be potentiometer,
Any one in refrigerator temperature sensor and blower fan, the embodiment of the present invention is said so that failure electric elements are blower fan as an example
It is bright.
Step 202, the corresponding relation according to electric elements and fault type, determine the fault type of the failure, perform
Step 203.
Example, the corresponding table of electric elements and fault type is prestored in refrigerator, as shown in table 3.
3rd corresponding table of the electric elements of table 3 and fault type
| Electric elements | Fault type |
| Potentiometer | Potentiometer failure |
| Refrigerator temperature sensor | Refrigeration sensing failure |
| Blower fan | Fan trouble |
Because the embodiment of the present invention assumes that failure electric elements are blower fan, you can it is blower fan event to determine the fault type of refrigerator
Fan trouble can also be subdivided into according to the particular location broken down in blower fan by different failure classes in barrier, practical application
Type, the embodiment of the present invention will not be described here.One fault flag of every kind of fault type correspondence, for marking whether refrigerator goes out
Corresponding fault type is showed.Example, when blower fan breaks down, corresponding fault type is fan trouble, and control panel will
The corresponding fault flag of fan trouble is set to effectively, represent that refrigerator occurs in that fan trouble.
Whether step 203, the door switch of the refrigerating chamber of the detection refrigerator are closed；When the refrigeration of the refrigerator
When the door switch of room is closed, step 204 is performed；When the door switch of the refrigerating chamber of the refrigerator is in opening
When, perform step 209.
After it is determined that fan trouble occurs in refrigerator, indicating fault is carried out for the ease of maintenance needs.But if refrigeration
Room illumination lamp occurs in refrigerator after fan trouble, that is, starts continuous non-stop carry out indicating fault, then can cause electric energy
Waste, while influenceing the normal of user to use, therefore only can be indicated when maintenance personal's startup separator is indicated and switched, it is real
In the application of border, it can be switched using the door switch of compartment as indicating fault, with the door switch of refrigerating chamber in the embodiment of the present invention
Switched as indicating fault, when the door switch of the refrigerating chamber is closed, represent that now user uses refrigerator, therefore illumination
Lamp is normally lighted；When the door switch of the refrigerating chamber is closed, represent that now user need not refrigerate room illumination lamp and be illuminated,
Therefore indicating fault can be carried out.
Explanation is needed, the door switch of the refrigerating chamber described in the embodiment of the present invention, which is closed, does not imply that refrigerating-chamber door is really closed
Close, and refer to that the door switch of refrigerating chamber is closed, in the case where refrigerating-chamber door is opened, maintenance personal can also be manual
The door switch of refrigerating chamber is closed, does not influence so the normal of user to use, while also allowing for making maintenance personal
Fault type is solved, is repaired.Certainly in the case where the door of refrigerating chamber is closed, refrigerating-chamber door switch is similarly in closing shape
State, can also carry out indicating fault.
Step 204, detect on this electricity after, when whether the continuous firing duration of the refrigerator is less than or equal to default
It is long；When the continuous firing duration of the refrigerator is less than or equal to preset duration, step 205 is performed；When continuing for the refrigerator
When operating time is more than or equal to preset duration, step 209 is performed.
In actual applications, only in maintenance personal it should be understood that during the fault type of refrigerator, just needing refrigerating chamber to illuminate
Lamp carry out indicating fault, when refrigerator break down but without repaired this during, can without indicating fault,
Therefore before indicating fault is carried out, it can also determine whether to need to be indicated.Because maintenance personal ties up to refrigerator
When repairing, it usually needs initialization refrigerator, i.e., re-powered after being powered off to refrigerator, it is possible to shorter after electricity on refrigerator
Fault indication function is realized in time, so before indicating fault is carried out, can first determine whether after electricity to continue on refrigerator
Whether operating time is less than or equal to preset duration, and the preset duration is pre-set as the case may be in practical application
, generally it could be arranged to 10 minutes, i.e., in 10 minutes on refrigerator after electricity, refrigeration room illumination lamp can obtain event first
Hinder the information of flag bit, judge which fault flag represents effective, then obtain the fault type of refrigerator, and then carry out event
Hinder the instruction of type, after 10 minutes, refrigeration room illumination lamp only carries out normally illuminating work, without indicating fault,
It is easy to economize on resources, while not influenceing Consumer's Experience.
Whether step 205, the number of times of this instruction fault type of the detection refrigerator are less than or equal to default time
Number；When this of the refrigerator indicates that the number of times of the fault type is less than or equal to preset times, step 206 is performed；When
When the number of times of this instruction fault type of the refrigerator is more than preset times, step 209 is performed.
Specifically, in preset duration on refrigerator after electricity, and refrigerating-chamber door switch is when being closed, if cold
Hide room illumination lamp to be continued for constantly carrying out indicating fault, then the unnecessary waste of power resource can be caused, while frequently
Multiple flicker can also cause to damage to refrigeration room illumination lamp, therefore can pre-set the preset times of indicating fault, when event
When the number of times that barrier is indicated reaches preset times, refrigeration room illumination lamp can normally extinguish or normal illumination, refer to realizing failure
While showing, resource has been saved.For the ease of distinguishing, there may be the second prefixed time interval between adjacent instruction twice.
Example, it is assumed that preset times are 2 times, then when fan trouble occurs in refrigerator, can indicate twice of fan trouble,
It is also possible that the situation of various faults occurs in refrigerator in practical application, it is assumed that refrigerator occurs in that fan trouble and potentiometer simultaneously
Failure, because the priority of blower fan is higher than the priority of potentiometer, therefore in indicating fault, can enter according to priority orders
Row indicates there is the 3rd prefixed time interval between two indicating fault, i.e., indicate first between fan trouble, the 3rd preset time
The indicating potential device failure after, again indicates that fan trouble after the second prefixed time interval, the 3rd prefixed time interval it
Indicating potential device failure, now completes indicating fault twice afterwards, and each indicating fault includes the instruction of two fault types.
Step 206, according to fault type and the corresponding relation of illuminating lamp flashing times, determine that the fault type is corresponding
Illuminating lamp flashing times, perform step 207.
Example, different fault types can be indicated by the difference of illuminating lamp flashing times, it is adjacent to flash it twice
Between to there is prefixed time interval in prefixed time interval, the embodiment of the present invention can be 0.5s (second).It is common, can be with refrigerator
The corresponding table of fault type and illuminating lamp flashing times is prestored, as shown in table 4,
The corresponding table of the fault type of table 4 and illuminating lamp flashing times
| Fault type | Illuminating lamp flashing times |
| Potentiometer failure | Flicker 2 times |
| Refrigeration sensing failure | Flicker 4 times |
| Fan trouble | Flicker 6 times |
Because refrigerator occurs in that fan trouble, therefore when refrigeration room illumination lamp carries out indicating fault every time, indicate blower fan
Failure needs flicker 6 times.
Step 207, the instruction illuminating lamp perform step 208 according to line flicker is entered described in illuminating lamp flashing times.
When determining that fan trouble needs to flash 6 times, when needing to carry out indicating fault, it can to refrigerate room illumination lamp
It is continuous to flash 6 times, it is separated by 0.5s between adjacent flicker twice, you can complete the instruction of fan trouble.Example, the photograph of refrigerating chamber
The process of bright lamp progress indicating fault is to flash 6 times, is separated by 0.5s between adjacent flicker twice, then extinguishes and complete this event
Barrier is indicated.
Assuming that in practical application, refrigerator is occurred in that to be deposited between fan trouble and potentiometer failure, two neighboring indicating fault
In 2s time interval, then the process that the illuminating lamp of refrigerating chamber carries out indicating fault is to flash 6 times first, adjacent to flash twice
Between be separated by 0.5s, then extinguish 2s, then flash 2 times, it is adjacent twice flash between be separated by 0.5s, then extinguish, you can complete
Into this indicating fault.
Step 208, the number of times of indicating fault add 1, perform step 205.
Often complete primary fault to indicate, you can add 1 by indicating fault number of times, then whether failure judgement indicates number of times again
