Specific implementation method
In the present embodiment, as shown in figure 1, a kind of breakdown of refrigerator operation method, is applied to by master control circuit board, display Plate, temperature sensor, heater, refrigeration system, door switch, environment temperature sensor, refrigerated storage temperature sensor, cryogenic temperature In the refrigerator control system of sensor and defrost temperature sensor composition, refrigerator control system is using master control circuit board as control core The heart.Environment temperature sensor, refrigerated storage temperature sensor, cryogenic temperature sensor, defrost temperature sensor, door switch are used as detection Device, master control circuit board by detection means gather information, judge refrigerator run it is whether normal so that control heater with And the operation of refrigerating plant.Once detection is out of order, it will be run by corresponding failure operation mode, and show on the display panel Failure code is fault mode title.
A kind of refrigerator of use breakdown of refrigerator operation method, is, according to the different fault mode of refrigerator, to set out corresponding Failure operation mode, with ensure refrigerator nonserviceable under normal safe and reliable operation;
Fault mode includes:By environment temperature temperature sensor failure, refrigerated storage temperature sensor fault, cryogenic temperature sensor The temperature sensor fault of failure and defrost temperature sensor fault composition, communication failure, freezing defrost failure, freezing are freezed not Sufficient failure and door switch failure;
The corresponding breakdown of refrigerator method of operation includes:It is the temperature sensor fault method of operation, the communication failure method of operation, cold Freeze defrost failure operation mode, freezing refrigeration deficiency failure operation mode and door switch failure automatic displaying method.
When refrigerated storage temperature sensor or cryogenic temperature sensor failure, master control circuit board utilizes refrigeration system Freeze the t1 times according to first refrigerating chamber, then the refrigeration chamber t1 times, the sequential loop operation of last compressor shutdown t1 times; 0 minute < t1≤60 minute;
As shown in figure 3, when refrigerated storage temperature sensor detects temperature less than -50 DEG C or higher than 70 DEG C, main control circuit Plate is judged as refrigerated storage temperature sensor fault, and now refrigerator can not normally judge the temperature of refrigerating chamber, it is impossible to normal operation, ice Case will according to refrigerating chamber freeze a period of time, refrigeration chamber for a period of time, compressor shutdown for a period of time, circular flow;It is aobvious Show that plate shows failure code.Refrigerating chamber, refrigeration chamber and compressor shutdown time range are 0 to 60 minute.
As shown in figure 4, when cryogenic temperature sensor detects temperature less than -50 DEG C or higher than 70 DEG C, main control circuit Plate is judged as cryogenic temperature sensor fault, and now refrigerator can not normally judge the temperature of refrigerating chamber, it is impossible to normal operation, ice Case will according to refrigerating chamber freeze a period of time, refrigeration chamber for a period of time, compressor shutdown for a period of time, circular flow;It is aobvious Show that plate shows failure code.Refrigerating chamber, refrigeration chamber and compressor shutdown time range are 0 to 60 minute.
As shown in Fig. 2 when environment temperature sensor detects temperature less than -50 DEG C or higher than 70 DEG C, main control circuit Plate is judged as environment temperature sensor failure, and now refrigerator can not normally judge ambient temperature;When environment temperature sensing When device breaks down, environment temperature default setting is operation between 25 ± 3 DEG C by master control circuit board;And show on the display panel Failure code, it is preferred that environment temperature is set to 25 DEG C.
As shown in figure 5, when defrost temperature sensor detects temperature less than -50 DEG C or higher than 70 DEG C, main control circuit Plate is judged as defrost temperature sensor fault, and is pointed out using the display board.When defrosting sensor breaks down, ice Case master control circuit board closes defrosting heater immediately, and refrigerator skips defrost program, does not perform defrosting operation, and set by original Freezer temperature and temperature of refrigerating chamber temperature operation;, could normal defrost operation until defrosting sensor trouble shooting.
As shown in fig. 6, being connected between display board and master control circuit board by communication line, refrigerator is in normal course of operation In, when display board is damaged or communication line is damaged, i.e., in the case of the communication line of display board and master control circuit board is interrupted, Now master control circuit board does not collect the freezer temperature and temperature of refrigerating chamber of display board setting, and master control circuit board is judged as Communication failure;And pointed out using the display board.Run simultaneously according to the communication failure method of operation:Master control circuit board is pressed Run according to freezer temperature and temperature of refrigerating chamber to ensure that refrigerator being capable of safe and reliable operation.
As shown in fig. 7, when unfinished defrost in t2 minutes occur in the continuous n times of refrigerator;N≥3;t2≥60;That is refrigerator continuous 3 The secondary defrost time, it was defrost failure that then master control circuit board, which judges, more than 60 minutes;And pointed out using the display board.This Under the state of kind, freezing defrost failure operation mode is:Master control circuit board closes heater immediately, skips defrost program, no Defrosting operation, and the freezer temperature by original setting and temperature of refrigerating chamber operation are performed, until freezing defrost trouble shooting, Can normally it run.
As shown in figure 8, being higher than T2 DEG C when the continuous t3 of refrigerating chamber is small;t3≥6;T2≥-10;That is freezer compartment of refrigerator continuous 6 Hour is higher than -10 DEG C, then master control circuit board judges it is freezing refrigeration deficiency failure, and is pointed out using the display board. Freezer temperature and temperature of refrigerating chamber operation that now master control circuit board is set by user, and display board shows failure code, Remind user's refrigeration for refrigerator not enough.
As shown in figure 9, door switch failure automatic displaying method is:When refrigerator doors are not fastened or door switch breaks down When, then it is that door switch breaks down that master control circuit board, which judges, then master control circuit board shows that failure code is entered using display board Row prompting, different door shows different failure codes.Once alarm release, failure code display is eliminated, this function is convenient to be tieed up The person of repairing accurately judges specific trouble point, simplifies maintenance flow.
