[0001] The present application relates to the technical field of refrigerators, in particular to a multi-system refrigerator control method and device, a storage medium and a refrigerator. BACKGROUND

[0002] A multi-system refrigerator such as a dual-system refrigerator usually has a refrigeration evaporator and a freezing evaporator for refrigeration and freezing, respectively, and an electromagnetic valve is provided to switch the refrigeration of the refrigeration evaporator and the freezing evaporator. However, in use, the electromagnetic valve may be stuck in the refrigeration evaporator branch or the freezing evaporator branch due to loss of synchronization, resulting in a series of problems and causing the refrigeration to fail.

[0003] Currently, the electromagnetic valve is reset once every fixed period (for example, 24 hours). However, the fixed period is usually too long or too short. If the fixed period is too long, the above problem cannot be solved in time, and if the fixed period is too short, the normal refrigeration in the refrigerator will be affected.

[0004] Therefore, the reliability of the abnormality processing of the stuck electromagnetic valve caused by loss of synchronization in the multi-system refrigerator is poor, and the refrigeration reliability of the refrigerator is poor. SUMMARY

[0008] In some embodiments, the detection of whether the refrigeration defrosting condition of the refrigeration evaporator is met comprises: detecting refrigeration data of a refrigeration branch in which the refrigeration evaporator is located; and determining whether the refrigeration defrosting condition of the refrigeration evaporator is met according to the refrigeration data.

[0009] In some embodiments, the refrigeration refrigeration data comprises a single refrigeration duration of the refrigeration branch; and the determining whether the active defrosting condition of the refrigeration evaporator is reached according to the refrigeration refrigeration data comprises: determining whether the single refrigeration duration exceeds a predetermined duration threshold; and if yes, determining that the active defrosting condition of the refrigeration evaporator is reached.

[0011] In some embodiments, the refrigeration refrigeration data comprises a single refrigeration duration of the refrigeration branch and a refrigeration chamber temperature in a predetermined time period; and the determining whether the active defrosting condition of the refrigeration evaporator is reached comprises: determining whether the single refrigeration duration exceeds a predetermined duration threshold and whether a variation of the refrigeration chamber temperature in the predetermined time period is less than a predetermined variation threshold; and if yes, determining that the active defrosting condition of the refrigeration evaporator is reached.

[0012] In some embodiments, the determining whether the active defrosting condition of the refrigeration evaporator is reached comprises: detecting pressures of multiple positions on a surface of the refrigeration evaporator; and determining whether the active defrosting condition of the refrigeration evaporator is reached according to the pressures of the multiple positions.

[0013] In some embodiments, the determining whether the active defrosting condition of the refrigeration evaporator is reached according to the pressures of the multiple positions comprises: calculating pressure differences of the pressures of the multiple positions; and if there is a pressure difference greater than a predetermined pressure threshold, determining that the active defrosting condition of the refrigeration evaporator is reached.

[0014] According to an embodiment of the present application, a multi-system refrigerator control device comprises: a memory storing a computer program; and a processor reading the computer program stored in the memory to execute the method described in the embodiments of the present application.

[0015] According to another embodiment of the present application, a storage medium stores a computer program, which, when executed by a processor of a multi-system refrigerator control device, causes the multi-system refrigerator control device to execute the method described in the embodiments of the present application.

[0016] According to another embodiment of the present application, a refrigerator can comprise the multi-system refrigerator control device described in the embodiments of the present application.

A processor of a multi-system refrigerator control device reads the computer instructions from the computer readable storage medium, and the processor executes the computer instructions to cause the multi-system refrigerator control device to perform the method provided in various optional implementations described in embodiments of the present application.

[0018] In embodiments of the present application, a multi-system refrigerator includes a refrigeration evaporator, a freezing evaporator, and a solenoid valve for switching refrigeration between the refrigeration evaporator and the freezing evaporator. The multi-system refrigerator control method includes detecting whether a forced defrosting condition of the refrigeration evaporator is met, the forced defrosting condition not including triggering refrigeration defrosting of the refrigeration evaporator when the freezing evaporator meets a freezing defrosting condition. If so, a reset operation is performed on the solenoid valve. If the reset operation is completed, a refrigeration defrosting operation is performed to defrost the refrigeration evaporator.

[0026] The present disclosure will be further described in conjunction with the drawings and embodiments. It should be understood that the embodiments provided herein are only used to explain the present disclosure and not intended to limit the present disclosure. In addition, the embodiments provided below are used to implement part of the present disclosure, and the technical solutions described in the embodiments of the present disclosure can be implemented in any combination manner without conflict.

[0027] It should be noted that in the embodiments of the present disclosure, the terms "comprise", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the method or device comprising a series of elements not only includes the elements explicitly described, but also includes other elements not explicitly listed, or includes elements inherent in the implementation of the method or device. Without more limitations, the element defined by the statement "comprises a" does not exclude the presence of other related elements (such as steps in the method or units in the device, for example, the unit can be part of the circuit, part of the processor, part of the program or software, etc.) in the method or device comprising the element.

[0028] For example, the electromagnetic valve control method provided by the embodiments of the present disclosure comprises a series of steps, but the electromagnetic valve control method provided by the embodiments of the present disclosure is not limited to the steps described, and similarly, the multi-system refrigerator control apparatus provided by the embodiments of the present disclosure comprises a series of units, but the apparatus provided by the embodiments of the present disclosure is not limited to comprising the units explicitly described, and can also comprise units required to be set when obtaining relevant information or processing based on information.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0030] It can be understood that in the specific embodiments of the present application, relevant data is involved, and when the embodiments in the present application are applied to specific products or technologies, the permission or consent of the user needs to be obtained, and the collection, use and processing of relevant data need to comply with relevant laws, regulations and standards of relevant countries and regions.

[0031] Figure 1A flow chart of a multi-system refrigerator control method according to an embodiment of the present application is shown schematically. The execution subject of the multi-system refrigerator control method can be any control device with processing capability, such as a refrigerator, a mobile phone, a computer, a smart watch, and other home appliances, etc. In a specific embodiment of the present application, the control device as the execution subject of the multi-system refrigerator control method is specifically the refrigerator itself, and the multi-system refrigerator control is performed by the controller in the refrigerator as the multi-system refrigerator control device.

[0032] The multi-system refrigerator includes a refrigeration evaporator, a freezing evaporator, and a solenoid valve for switching the refrigeration between the refrigeration evaporator and the freezing evaporator. As shown in Figure 1 The multi-system refrigerator control method can include steps S110 to S130.

[0033] Step S110, detecting whether the active defrosting condition of the refrigeration evaporator is reached, the active defrosting condition does not include the refrigeration defrosting of the refrigeration evaporator triggered when the freezing evaporator meets the freezing defrosting condition; step S120, if yes, performing a reset operation on the solenoid valve; step S130, if the reset operation is completed, performing a refrigeration defrosting operation for defrosting the refrigeration evaporator.

[0034] In the embodiment of the present application, the defrosting triggering condition of the refrigeration evaporator in the multi-system refrigerator is divided into an active defrosting condition and a passive defrosting condition. The passive defrosting condition is "when the freezing evaporator meets the preset freezing defrosting condition, the refrigeration defrosting of the refrigeration evaporator is also triggered", and the active defrosting condition is the condition for triggering the defrosting of the refrigeration evaporator other than the passive defrosting condition.

[0035] When the passive defrosting condition is met, the solenoid valve is switched to the freezing branch (i.e. the refrigeration branch where the freezing evaporator is located) and the refrigeration fan is turned on for defrosting, and at this time the compressor is closed and neither the refrigeration evaporator nor the freezing evaporator performs refrigeration. When the active defrosting condition is met, the solenoid valve is first reset, and if the reset operation is completed, the refrigeration defrosting operation is then performed (i.e. the solenoid valve is switched to the freezing branch (i.e. the freezing evaporator can still control the refrigeration of the freezing compartment), and the refrigeration fan is turned on to defrost the refrigeration evaporator by using the hot air in the refrigeration compartment driven by the fan).

[0036] When the electromagnetic valve is stuck in the freezing branch due to step loss, the freezing evaporator continues to have no cooling capacity, the freezing evaporator temperature cannot be reduced, and if the active defrosting condition of the freezing evaporator is triggered, freezing defrosting abnormality occurs, causing freezing refrigeration failure. When the electromagnetic valve is stuck in the freezing branch due to step loss, the frost amount on the freezing evaporator is gradually increased, and even if the active defrosting condition of the freezing evaporator is triggered, the freezing fan has been started, but in the process of freezing refrigeration, the freezing evaporator continues to refrigerate and frost, and the freezing evaporator is defrosted only when the freezing refrigeration compressor is stopped. The freezing evaporator alternates between defrosting and refrigeration at the freezing period, and each defrosting is not complete, but rather exacerbates the frost amount on the freezing evaporator, causing freezing refrigeration failure.

[0037] When the active defrosting condition is detected in the embodiment of the application, the electromagnetic valve is first reset, and if the reset operation is completed, the freezing defrosting operation (i.e. the electromagnetic valve switches to the freezing path and the freezing fan is started) is performed to defrost the freezing evaporator. The electromagnetic valve stuck due to step loss can be restored at a very reasonable time, and the above problems caused by the electromagnetic valve stuck can be avoided.

[0038] Further, in the embodiment of the application, when the active defrosting condition of the freezing evaporator is detected in the multi-system refrigerator, the electromagnetic valve is first reset, and after the reset operation is completed, the freezing defrosting operation is performed to defrost the freezing evaporator. The active defrosting condition does not include the freezing defrosting of the freezing evaporator triggered when the freezing evaporator satisfies the freezing defrosting condition, which can reliably restore the electromagnetic valve stuck due to step loss in the multi-system refrigerator, reliably avoid the electromagnetic valve stuck in the freezing evaporator branch or the freezing evaporator branch due to step loss, and further improve the reliability of the electromagnetic valve stuck due to step loss in the multi-system refrigerator. The reliability of the freezing refrigeration in the multi-system refrigerator is improved.

[0039] The following describes Figure 1 When the multi-system refrigerator is controlled in the embodiment, the further optional specific embodiments of each step are described.

[0040] In one embodiment, referring to Figure 2 The detection of whether the active defrosting condition of the freezing evaporator is met can include: step S210, detecting freezing refrigeration data of a freezing branch in which the freezing evaporator is located; and step S220, determining whether the active defrosting condition of the freezing evaporator is met according to the freezing refrigeration data.

[0041] The refrigeration data of the refrigeration branch circuit of the refrigerator refers to relevant data in the refrigeration branch circuit of the refrigerator. The refrigeration data of the refrigeration branch circuit can include but is not limited to the length of single refrigeration and the temperature of the refrigeration chamber and the like. The refrigeration data of the refrigeration branch circuit can reflect the working condition of the refrigeration evaporator, and then, according to the refrigeration data of the refrigeration branch circuit, it can be determined whether the active defrosting condition of the refrigeration evaporator is reached.

[0042] In one embodiment, the refrigeration data of the refrigeration branch circuit includes the length of single refrigeration of the refrigeration branch circuit. Whether the active defrosting condition of the refrigeration evaporator is reached can be determined according to the refrigeration data of the refrigeration branch circuit, which can specifically include: judging whether the length of single refrigeration exceeds a predetermined length threshold (for example, 1 hour); if yes, it is determined that the active defrosting condition of the refrigeration evaporator is reached.

[0043] The length of single refrigeration refers to the length of refrigeration after the refrigeration is started in the refrigeration branch circuit. If the length of single refrigeration exceeds the predetermined length threshold, it can reflect that the refrigeration evaporator is most likely to be blocked by frost, so that the active defrosting condition of the refrigeration evaporator is judged to trigger the reset operation of the electromagnetic valve and the defrosting of the refrigeration evaporator, which can reasonably recover the abnormal blocking of the electromagnetic valve.

[0044] Further, in one embodiment, the refrigeration data of the refrigeration branch circuit includes the temperature of the refrigeration chamber in a predetermined time period after the refrigeration is started in the refrigeration branch circuit. Whether the active defrosting condition of the refrigeration evaporator is reached can be determined according to the refrigeration data of the refrigeration branch circuit, which can include: calculating the change amount of the temperature of the refrigeration chamber in the predetermined time period; and determining whether the active defrosting condition of the refrigeration evaporator is reached according to whether the change amount is less than a predetermined change threshold.

[0045] The temperature of the refrigeration chamber in a predetermined time period after the refrigeration is started in the refrigeration branch circuit can be detected by the temperature sensor in the refrigeration chamber, and then the change amount of the temperature of the refrigeration chamber in the predetermined time period can be calculated. If the change amount is less than the predetermined change threshold, it is judged that the active defrosting condition of the refrigeration evaporator is reached to trigger the reset operation of the electromagnetic valve and the defrosting of the refrigeration evaporator, which can also reasonably recover the abnormal blocking of the electromagnetic valve.

[0046] Further, in one embodiment, referring to Figure 3 , the refrigeration data of the refrigeration branch circuit includes the length of single refrigeration of the refrigeration branch circuit and the temperature of the refrigeration chamber in a predetermined time period. Whether the active defrosting condition of the refrigeration evaporator is reached is detected, which includes: step S310, judging whether the length of single refrigeration exceeds a predetermined length threshold and judging whether the change amount of the temperature of the refrigeration chamber in the predetermined time period is less than a predetermined change threshold; and step S320, if yes, it is determined that the active defrosting condition of the refrigeration evaporator is reached.

[0047] The single refrigeration time length and the change amount of the temperature of the refrigeration chamber in the predetermined time period are comprehensively judged, if the single refrigeration time length exceeds the predetermined time length threshold and the change amount of the temperature of the refrigeration chamber in the predetermined time period is less than the predetermined change threshold, the active defrosting condition of the refrigeration evaporator is judged to be reached to trigger the resetting operation of the electromagnetic valve and the defrosting of the refrigeration evaporator, and the abnormal clamping of the electromagnetic valve can be further reasonably recovered.

[0048] In an embodiment, the detecting whether the active defrosting condition of the refrigeration evaporator is reached comprises: detecting pressures of multiple positions on the surface of the refrigeration evaporator; and determining whether the active defrosting condition of the refrigeration evaporator is reached according to the pressures of the multiple positions.

[0049] The multiple-position pressure sensors on the surface of the refrigeration evaporator can detect the pressures of multiple positions on the surface of the refrigeration evaporator, the pressures of the multiple positions can reflect the pressure situation caused by the frosting on the surface of the refrigeration evaporator, and whether the active defrosting condition of the refrigeration evaporator is reached can be accurately determined according to the pressures of the multiple positions.

[0050] In an embodiment, the determining whether the active defrosting condition of the refrigeration evaporator is reached according to the pressures of the multiple positions can comprise: calculating pressure differences of the pressures of the multiple positions; and determining that the active defrosting condition of the refrigeration evaporator is reached if there is a pressure difference greater than a predetermined pressure threshold.

[0051] The pressure differences between the pressures of the multiple positions can obtain multiple pressure differences, and the active defrosting condition of the refrigeration evaporator is determined to be reached if there is a pressure difference greater than a predetermined pressure threshold, so as to trigger the resetting operation of the electromagnetic valve and the defrosting of the refrigeration evaporator, and the abnormal clamping of the electromagnetic valve can be reasonably recovered.

[0052] In addition, the embodiment of the present application further provides a multi-system refrigerator control device, which can be applied to a control equipment.
