Description

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

[0002] Taking a dual-system refrigerator as an example, a multi-system refrigerator usually has a refrigeration evaporator and a freezing evaporator for refrigeration and freezing respectively, and switches the refrigeration of the refrigeration evaporator and the freezing evaporator by setting a solenoid valve. However, during use, the solenoid valve may get stuck in the refrigeration evaporator branch or the freezing evaporator branch due to loss of step, resulting in a series of problems that make the refrigeration evaporator ineffective.

[0003] The current approach to this problem is usually to set a fixed time (e.g., 24 hours) to reset the solenoid valve once. However, in the current approach, the set fixed time is usually too long or too short. If it is too long, the problem cannot be solved in time, while if it is too short, it will affect the normal refrigeration activity in the refrigerator.

[0028] For example, the solenoid valve control method provided in the embodiment of the present disclosure includes a series of steps, but the solenoid valve control method provided in the embodiment of the present disclosure is not limited to the recorded steps. Similarly, the multi-system refrigerator control device provided in the embodiment of the present disclosure includes a series of units, but the device provided in the embodiment of the present disclosure is not limited to including the units explicitly recorded, and may also include units that need to be set to obtain relevant information or perform processing based on information.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled 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 is understandable that in the specific implementation of this application, relevant data is involved. When the embodiments in this application are applied to specific products or technologies, user permission or consent is required, 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 1The flowchart of a multi-system refrigerator control method according to an embodiment of the present application is schematically shown. The execution subject of the multi-system refrigerator control method can be any control device with processing capabilities, such as a refrigerator, a mobile phone, a computer, a smart watch, and other household appliances. 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 is specifically controlled by a controller in the refrigerator as a multi-system refrigerator control device.

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

[0033] Step S110, detecting whether the active defrosting condition of the refrigerated evaporator is met, and the active defrosting condition does not include triggering the refrigerated defrosting of the refrigerated evaporator when the frozen evaporator meets the frozen defrosting condition; Step S120, if yes, resetting the solenoid valve; Step S130, if the reset operation is completed, executing the refrigerated defrosting operation, and the refrigerated defrosting operation is used to defrost the refrigerated evaporator.

[0034] In the embodiment of the present application, the defrosting triggering conditions of the refrigerating evaporator in the multi-system refrigerator are divided into active defrosting conditions and passive defrosting conditions. Among them, the passive defrosting condition is "when the freezing evaporator meets the preset freezing defrosting conditions, it also triggers the refrigerating evaporator to start the refrigerating defrosting once", and the active defrosting condition is the condition that triggers the defrosting of the refrigerating evaporator in addition to the passive defrosting condition.

[0035] When the passive defrosting conditions are met, the solenoid valve switches to the freezing branch (i.e. the refrigeration branch where the freezing evaporator is located) and the refrigeration fan is turned on for defrosting. Moreover, at this time, the compressor is turned off and neither the refrigeration evaporator nor the freezing evaporator is refrigerating. When the active defrosting conditions are met, the solenoid valve is reset first. If the reset operation is completed, the refrigeration defrosting operation is 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 use the fan to drive the hot air in the refrigeration compartment to defrost the refrigeration evaporator).

[0036] When the solenoid valve is stuck in the freezing branch due to a loss of synchronism, the refrigerated evaporator continues to have no cooling capacity, and the temperature of the refrigerated evaporator cannot be lowered. If the active defrosting condition of the refrigerated evaporator is triggered, the refrigerated defrosting abnormality will occur, making the refrigeration and refrigeration ineffective. When the solenoid valve is stuck in the refrigerated branch due to a loss of synchronism, the amount of frost on the refrigerated evaporator gradually increases. Even if the active defrosting condition of the refrigerated evaporator is triggered and the refrigeration fan is already turned on, the refrigerated evaporator continues to refrigerate and frost during the freezing and refrigeration process. The refrigeration is not defrosted until the refrigeration compressor is stopped. The refrigerated evaporator is defrosted during the freezing cycle or the alternation of defrosting and refrigeration. Each defrost is not thorough, but aggravates the amount of frost on the refrigerated evaporator, making the refrigeration and refrigeration ineffective.

[0037] When the embodiment of the present application detects that the active defrost conditions are met, the solenoid valve is reset first. If the reset operation is completed, the refrigeration defrost operation is performed (that is, the solenoid valve is switched to the freezing path and the refrigeration fan is turned on) to defrost the refrigeration evaporator. The solenoid valve can be restored from the abnormal position caused by the loss of step at a very reasonable time, while avoiding the above-mentioned problems caused by the solenoid valve being stuck.

[0038] Furthermore, according to the implementation method of the embodiment of the present application, when it is detected that the active defrost condition of the refrigerated evaporator is reached in the multi-system refrigerator, the solenoid valve is first reset, and after the reset operation is completed, the refrigerated defrost operation is performed to defrost the refrigerated evaporator, wherein the active defrost condition does not include triggering the refrigerated defrost of the refrigerated evaporator when the frozen evaporator meets the frozen defrost condition. The solenoid valve in the multi-system refrigerator can be reliably restored to the stuck position abnormality caused by loss of step, and the solenoid valve can be reliably prevented from being stuck in the refrigerated evaporator branch or the frozen evaporator branch due to loss of step, thereby improving the reliability of handling the stuck position abnormality caused by loss of step of the solenoid valve in the multi-system refrigerator, and improving the reliability of refrigeration and cooling in the multi-system refrigerator.

[0039] Described below Figure 1 When performing multi-system refrigerator control under the embodiment, further optional specific embodiments are provided for each step performed.

[0040] In one embodiment, see Figure 2 The detection of whether the active defrosting condition of the refrigerated evaporator is met may include: step S210, detecting the refrigeration data of the refrigeration branch where the refrigerated evaporator is located; step S220, determining whether the active defrosting condition of the refrigerated evaporator is met according to the refrigeration data.

[0041] Refrigeration data refers to the relevant data in the refrigeration branch of the refrigerator, and the refrigeration data may include but is not limited to single refrigeration duration and refrigeration room temperature. The refrigeration data can reflect the working condition of the refrigeration evaporator, and further, according to the refrigeration data, it can be accurately determined whether the active defrosting condition of the refrigeration evaporator is met.

[0042] In one embodiment, the refrigeration data includes a single refrigeration time of the refrigeration branch; determining whether the active defrosting condition of the refrigeration evaporator is met based on the refrigeration data may specifically include: judging whether the single refrigeration time exceeds a predetermined time threshold (for example, 1 hour); if so, determining that the active defrosting condition of the refrigeration evaporator is met.

[0043] The duration of refrigeration after the refrigeration is turned on once in the refrigeration branch is the single refrigeration duration. If the single refrigeration duration exceeds the preset time threshold, it can reflect that the refrigeration evaporator is very likely to be blocked by frost. Therefore, it is judged that the active defrosting condition of the refrigeration evaporator is met to trigger the resetting operation of the solenoid valve and defrost the refrigeration evaporator, so as to reasonably restore the abnormal solenoid valve jam.

[0044] Furthermore, in one embodiment, the refrigeration and cooling data include the temperature of the cold storage room within a predetermined time period after refrigeration is started in the refrigeration branch; determining whether the active defrosting condition of the refrigeration evaporator is met based on the refrigeration and cooling data may include: calculating the change in the temperature of the cold storage room within the predetermined time period; and determining whether the active defrosting condition of the refrigeration evaporator is met based on whether the change is less than a predetermined change threshold.

[0045] The temperature sensor in the cold storage room can detect the temperature of the cold storage room within a predetermined time period after the refrigeration is started in the cold storage branch. Furthermore, the change in the temperature of the cold storage room within the predetermined time period can be calculated. If the change is less than the predetermined change threshold, it is determined that the active defrosting condition of the refrigeration evaporator is met to trigger the resetting operation of the solenoid valve and the defrosting of the refrigeration evaporator. The solenoid valve stuck abnormality can also be reasonably restored.

[0046] Further, in one embodiment, see Figure 3 , the refrigeration data includes the single refrigeration time of the refrigeration branch and the temperature of the refrigeration chamber within a predetermined time period; the detection of whether the active defrosting condition of the refrigeration evaporator is met includes: step S310, judging whether the single refrigeration time exceeds the predetermined time threshold, and judging whether the change of the refrigeration chamber temperature within the predetermined time period is less than the predetermined change threshold; step S320, if so, determining that the active defrosting condition of the refrigeration evaporator is met.

[0047] A judgment is made based on the single refrigeration time and the change in the refrigeration chamber temperature within a preset time period. If the single refrigeration time exceeds the preset time threshold and the change in the refrigeration chamber temperature within the preset time period is less than the preset change threshold, it is judged that the active defrosting conditions of the refrigeration evaporator are met to trigger the resetting operation of the solenoid valve and the defrosting of the refrigeration evaporator. The solenoid valve stuck abnormality can be further reasonably restored.

[0048] In one embodiment, the detecting whether the active defrosting condition of the refrigerated evaporator is met includes: detecting the pressure at multiple positions on the surface of the refrigerated evaporator; and determining whether the active defrosting condition of the refrigerated evaporator is met based on the pressure at the multiple positions.

[0049] There are pressure sensors at multiple positions on the surface of the refrigerated evaporator. The pressures at multiple positions on the surface of the refrigerated evaporator can be detected by the pressure sensors at multiple positions. The pressures at multiple positions can reflect the pressure conditions caused by frost on the surface of the refrigerated evaporator. According to the pressures at multiple positions, it can also be accurately determined whether the active defrosting conditions of the refrigerated evaporator are met.

[0050] In one embodiment, determining whether the active defrost condition of the refrigerated evaporator is met based on the pressures at the multiple positions may include: calculating the pressure difference of the pressures at the multiple positions; if there is a pressure difference greater than a predetermined pressure threshold, determining that the active defrost condition of the refrigerated evaporator is met.

[0051] By calculating the pressure difference between any two of the multiple positions, multiple pressure differences can be obtained. If there is a pressure difference among the multiple pressure differences that is greater than a predetermined pressure threshold, it is determined that the active defrosting condition of the refrigerated evaporator is met to trigger the resetting operation of the solenoid valve and defrost the refrigerated evaporator. The solenoid valve stuck abnormality can also be reasonably restored.

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