[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

A non-transitory computer-readable storage medium includes any suitable medium for storing program code, such as magnetic disks, hard disks, optical discs, flash memories, read-only memories, random access memories, and the like.
[0035] The embodiments of the present application provide a refrigerator, a control method thereof, a control device, and a storage medium to solve the problem that after frosting appears on the inner wall of the compartment of an existing refrigerator, manual cleaning is required, which is time-consuming and laborious and affects the normal operation of the refrigerator. The following will be described with reference to the accompanying drawings. The reason for frosting on the inner wall of the refrigerator compartment will not be further elaborated here. In some examples, it may be that the compartment door is opened for too long, resulting in more wet air entering the compartment. In other examples, it may be that the stored items are overheated, and so on.
[0036] The control method of the refrigerator provided by the embodiments of the present application, the refrigerator includes a storage compartment, an evaporator 8, and a blower 9. The blower 9 is used to blow the cold air of the evaporator 8 into the storage compartment. Please refer to Figure 1 , and the method includes the following steps:
[0037] Step S101: If it is detected that frosting appears in the storage compartment, determine the heating cycle of the evaporator 8 based on the defrosting cycle of the evaporator 8;
[0038] Step S102: After the refrigerator enters the heating cycle of the evaporator 8, control the evaporator 8 to heat up and control the blower 9 to remain in the on state;
[0039] Step S103: After the refrigerator enters the defrosting cycle of the evaporator 8, defrost the evaporator 8.
[0040] The control method of the refrigerator provided by the embodiment of the present application, after frosting appears on the wall surface of the storage compartment of the refrigerator, determines the heating-up period of the evaporator 8 according to the defrosting period of the evaporator 8, and when the refrigerator runs to the heating-up period, controls the evaporator 8 to heat up, and blows the cold air with increased temperature to the storage compartment through the blower 9. At this time, the cold air with increased temperature exchanges heat with the frost in the storage compartment, thereby melting the frost layer. The melted water vapor follows the refrigerant into the loop of the refrigeration cycle and condenses into frost again at the evaporator 8, realizing the transfer of the frost in the storage compartment to the evaporator 8, and during the defrosting period of the evaporator 8, concentrating on defrosting the frost layer on the evaporator 8, which not only realizes defrosting in the storage compartment, but also does not affect the normal operation of the refrigerator, and realizes automatic control, without manual cleaning, saving time and effort.
[0041] It should be noted that the refrigerator in the present application is an air-cooled refrigerator. The storage compartment mentioned in this article can be a refrigerating compartment or a freezing compartment. When the storage compartment is a refrigerating compartment, the evaporator 8 corresponds to the refrigerating evaporator 8, and the blower 9 corresponds to the refrigerating blower 9. When the storage compartment is a freezing compartment, the evaporator 8 corresponds to the freezing evaporator 8, and the blower 9 corresponds to the freezing blower 9.
[0042] No further limitation is made on the specific heating-up temperature value for controlling the evaporator 8 to heat up in step S102. The specific heating-up temperature value can be determined through multiple experiments, as long as the temperature impact on the storage compartment after heating up is not significant. For example, the temperature increase of the storage compartment caused by the heating up of the evaporator 8 does not exceed 3°C.
[0043] Optionally, determining the heating-up period of the evaporator 8 based on the defrosting period of the evaporator 8 in step S101 includes: determining the preset time period before the defrosting period of the evaporator 8 as the heating-up period of the evaporator 8. In some examples, the preset time period can be half an hour; in other examples, the preset time period can be one hour.
[0044] That is, the time period within half an hour or one hour before the defrosting period of the evaporator 8 is determined as the heating-up period of the evaporator 8. Before defrosting the evaporator 8, first raise the temperature of the evaporator 8 to realize the transfer of the frost in the storage compartment to the evaporator 8 through the refrigeration cycle, and then defrost the evaporator 8 during the defrosting period of the evaporator 8 to improve the defrosting efficiency.
[0045] Optionally, please refer to Figure 3 , the refrigerator further includes an electronic expansion valve 4 connected to the evaporator 8. The opening degree of the electronic expansion valve 4 is adjustable. Controlling the evaporator 8 to heat up includes: controlling the opening degree of the electronic expansion valve 4 to increase. No further limitation is made on the increase value of the opening degree of the electronic expansion valve 4.
[0046] By controlling the increase in the opening degree of the electronic expansion valve 4, the flow rate of the refrigerant is increased, enabling more refrigerant to enter the evaporator 8. The pressure inside the evaporator 8 then rises. According to the thermodynamic properties of the refrigerant, the evaporation pressure is positively correlated with the evaporation temperature (the higher the pressure, the higher the saturation temperature). Therefore, the evaporation temperature will increase. At the same time, the increase in the refrigerant flow rate causes the refrigerant inside the evaporator 8 to pass through more quickly, shortening the heat absorption time, which may lead to insufficient evaporation of the refrigerant and a decrease in superheat, further exacerbating the increase in the temperature of the evaporator 8. Finally, if the suction volume of the compressor 1 remains unchanged, the increase in the evaporation pressure will reduce the pressure difference of the system, that is, the difference between the condensation pressure and the evaporation pressure, resulting in a decrease in the efficiency of the compressor 1 and a weakening of the overall refrigeration effect, causing the temperature of the evaporator 8 to remain at a relatively high level.
[0047] Optionally, please refer to Figure 2 , the refrigerator further includes a control valve 5. The control valve 5 is connected to the evaporator 8 through a first capillary tube 6, and the control valve 5 is also connected to the evaporator 8 through a second capillary tube 7. The control valve 5 can divert the refrigerant to the first capillary tube 6 or the second capillary tube 7. The flow rate of the first capillary tube 6 is less than that of the second capillary tube 7. Controlling the temperature rise of the evaporator 8 includes: controlling the control valve 5 to switch the refrigerant to be diverted to the second capillary tube 7.
[0048] That is, when the control valve 5 is connected to the evaporator 8 through two branches respectively, during the refrigeration stage, the control valve 5 can be connected to the evaporator 8 through the first capillary tube 6 with a smaller flow rate, and during the temperature rise stage, the control valve 5 can be connected to the evaporator 8 through the second capillary tube 7 with a larger flow rate, thereby increasing the flow rate of the refrigerant entering the evaporator 8, enabling more refrigerant to enter the evaporator 8. The pressure inside the evaporator 8 then rises. According to the thermodynamic properties of the refrigerant, the evaporation pressure is positively correlated with the evaporation temperature (the higher the pressure, the higher the saturation temperature). Therefore, the evaporation temperature will increase. At the same time, the increase in the refrigerant flow rate causes the refrigerant inside the evaporator 8 to pass through more quickly, shortening the heat absorption time, which may lead to insufficient evaporation of the refrigerant and a decrease in superheat, further exacerbating the increase in the temperature of the evaporator 8. Finally, if the suction volume of the compressor 1 remains unchanged, the increase in the evaporation pressure will reduce the pressure difference of the system, that is, the difference between the condensation pressure and the evaporation pressure, resulting in a decrease in the efficiency of the compressor 1 and a weakening of the overall refrigeration effect, causing the temperature of the evaporator 8 to remain at a relatively high level. Among them, the control valve 5 can be a three-way solenoid valve.
[0049] It can be understood that when the manufacturing cost requirements of the refrigerator are relatively low, the control valve 5 can be connected to the evaporator 8 through two branches respectively, and a capillary tube is provided on each of the two branches. The cost of the capillary tube is low, and the two parallel branches achieve adjustable flow rate of the refrigerant entering the evaporator 8. When the control accuracy requirements of the refrigerator are relatively high, the electronic expansion valve 4 can be connected to the evaporator 8. It can be selected according to needs.
[0050] Optionally, the refrigerator further includes a compressor 1 and a heating element for heating and defrosting the evaporator 8; defrosting the evaporator 8 includes: controlling the compressor 1 and the blower 9 to turn off and controlling the heating element to turn on. Wherein, the heating element can be a heating tube.
[0051] Optionally, the refrigerator further includes an infrared sensor disposed in the storage compartment; before determining the temperature rise cycle of the evaporator 8, the method includes: obtaining the frost accumulation amount in the storage compartment through the infrared sensor.
[0052] Optionally, after determining the temperature rise cycle of the evaporator 8, the method further includes: adjusting the duration of the temperature rise cycle based on the frost accumulation amount.
[0053] That is, after determining the timing and duration of the temperature rise cycle of the evaporator 8 according to the defrosting cycle of the evaporator 8, the duration of the temperature rise cycle can be further adaptively adjusted according to the frost accumulation amount, so that the duration of the temperature rise cycle is more matched with the frost accumulation amount in the storage compartment. It can be understood that the greater the frost accumulation amount in the storage compartment, the longer the duration of the temperature rise cycle, and the smaller the frost accumulation amount in the storage compartment, the shorter the duration of the temperature rise cycle.
[0054] It should be noted that if frost formation is detected in the storage compartment, the refrigerator directly enters the defrosting cycle after refrigeration, and the temperature rise cycle and subsequent control steps are no longer determined.
[0055] The embodiment of the present application further provides a control device for a refrigerator. The refrigerator includes a storage compartment, an evaporator 8, and a blower 9. The blower 9 is used to blow the cold air of the evaporator 8 into the storage compartment. Please refer to Figure 4 , the device includes an analysis module 10 and a control module 11. The analysis module 10 is configured to determine the temperature rise cycle of the evaporator 8 based on the defrosting cycle of the evaporator 8 if frost formation is detected in the storage compartment; the control module 11 is configured to control the evaporator 8 to heat up and control the blower 9 to remain on when the refrigerator enters the temperature rise cycle of the evaporator 8; when the refrigerator enters the defrosting cycle of the evaporator 8, defrost the evaporator 8.
[0056] The embodiment of the present application further provides a refrigerator, including a storage compartment, an evaporator 8, and a blower 9. The blower 9 is used to blow the cold air of the evaporator 8 into the storage compartment, and further includes a controller configured to perform the control method of the refrigerator as described above. The method includes the following steps: if frost formation is detected in the storage compartment, determine the temperature rise cycle of the evaporator 8 based on the defrosting cycle of the evaporator 8; when the refrigerator enters the temperature rise cycle of the evaporator 8, control the evaporator 8 to heat up and control the blower 9 to remain on; when the refrigerator enters the defrosting cycle of the evaporator 8, defrost the evaporator 8.
[0057] Optionally, the refrigerator further includes a condenser 2 and a dryer filter 3. The condenser 2 and the dryer filter 3 are sequentially connected between the compressor 1 and the control valve 5, or the condenser 2 and the dryer filter 3 are sequentially connected between the compressor 1 and the electronic expansion valve 4.
