[0047] The embodiments of the present application provide a defrosting method, a control device, an electronic device and a storage medium for a refrigerator to solve the problem of how to defrost the two evaporators connected in series when the two evaporators are connected in series through a compressor in an existing refrigerator and heat is exchanged with a refrigerating compartment and a freezing compartment respectively, so as to achieve synchronous termination of defrosting of the two evaporators connected in series. The method will be explained in conjunction with the accompanying drawings below.

[0048] The defrosting method of a refrigerator provided in an embodiment of the present application comprises a compressor, a refrigerating air duct, a freezing air duct, a refrigerating compartment and a freezing compartment, a first evaporator and a refrigerating fan are arranged in the refrigerating air duct, a second evaporator and a freezing fan are arranged in the freezing air duct, the first evaporator and the second evaporator are connected in series, and a heater is arranged on the second evaporator, and the method comprises the following steps:

[0049] Step S101: when the refrigerator reaches the defrosting condition, the compressor and the freezing fan are controlled to be turned off, and the refrigerating fan is controlled to be turned on to defrost the first evaporator, and a target delay time is determined based on the defrosting condition;

[0050] Step S102: After the target delay time, the heater is controlled to turn on to defrost the second evaporator;

[0051] Step S103: After the defrosting time is preset, the refrigeration fan and the heater are controlled to be turned off;

[0052] The preset defrost time is positively correlated with the amount of frost on the second evaporator.

[0053] The defrosting method of the refrigerator provided in the embodiment of the present application, when the refrigerator reaches the defrosting condition, since the temperature of the refrigerating compartment is usually higher than zero degrees Celsius, the first evaporator is defrosted using the temperature of the refrigerating compartment. Since the speed of this defrosting method is slow, the refrigerating fan is turned on first, and after the refrigerating fan is turned on, after the target delay time, the heater is turned on to defrost the second evaporator, and finally the refrigerating fan and the heater are turned off at the same time, so that the defrosting operation of the first evaporator and the second evaporator is terminated synchronously, and it is prevented that only one of the first evaporator and the second evaporator ends the defrosting first, thereby causing the refrigerating compartment or the freezing compartment to have a high temperature return and affect the preservation effect. That is, by delaying the opening of the heater to defrost the second evaporator, it is avoided to consume extra energy to achieve the defrosting effect of the first evaporator, saving energy consumption, and at the same time, it is ensured that the first evaporator and the second evaporator end the defrosting synchronously, and the preservation effect of the refrigerating compartment and the freezing compartment is ensured.

[0054] It can be understood that when the refrigeration fan is turned on, the flow of gas in the flow channel formed by the connection between the refrigeration air duct and the refrigeration compartment is accelerated. At the same time, since the temperature in the refrigeration compartment is usually higher than zero degrees Celsius, the airflow in the refrigeration compartment can exchange heat with the frost on the first evaporator in the refrigeration air duct when flowing in the flow channel, thereby melting the frost on the first evaporator and achieving the defrosting effect of the first evaporator, that is, only by turning on the refrigeration fan, the existing heat in the refrigeration compartment is used to achieve the defrosting of the first evaporator, thereby saving energy consumption.

[0055] The type of heater is not further limited here. For example, it can be an electric heater, a steam heater, a hot oil heater, a hot water heater, an infrared heater, a microwave heater or a hot air heater, etc., and can be selected according to actual needs.

[0056] Optionally, the defrost condition includes a first setting condition, a second setting condition and a third setting condition. Before executing step S101 of controlling the compressor and the refrigeration fan to be turned off and controlling the refrigeration fan to be turned on, the method further includes:

[0057] Step S1001: obtaining a first on-time of a refrigeration fan and a second on-time of a freezing fan in a refrigeration cycle;

[0058] Step S1002: if the first opening time is within the first preset range, and the second opening time is within the second preset range, when the refrigerator enters the defrost cycle, it is determined that the refrigerator meets the first set condition;

[0059] Step S1003: if the first opening time exceeds the first preset range and the second opening time is within the second preset range, it is determined that the refrigerator meets the second setting condition;

[0060] Step S1004: if the first opening time is within the first preset range and the second opening time exceeds the second preset range, it is determined that the refrigerator meets the third setting condition;

[0061] The first setting condition corresponds to a first delay time, the second setting condition corresponds to a second delay time, and the third setting condition corresponds to a third delay time, and the second delay time, the first delay time, and the third delay time decrease in sequence. In some examples, the first preset range may be one hour, and the second preset range may be four hours.

[0062] That is, during the refrigeration cycle, if the power-on time of the refrigeration fan and the freezing fan is within the preset range, it means that the refrigerator is operating normally. When the refrigerator operates normally and enters the defrost cycle, the defrost condition is naturally triggered; if during the refrigeration cycle, the power-on time of the refrigeration fan exceeds the first preset range, that is, exceeds the normal power-on time, it indicates that the heat exchange effect of the first evaporator is not good, and the first evaporator is blocked by frost and fails. Therefore, the defrost condition is directly triggered at this time to perform defrosting, and because the amount of frost on the first evaporator is large, the second delay time is longer than the first delay time, that is, the defrost time of the first evaporator is extended, compared with the normal operation of the refrigerator. When the refrigerator is in the default state, the second evaporator starts to defrost later to ensure that the first evaporator and the second evaporator can finish defrosting at the same time; if during the refrigeration cycle, the startup time of the refrigeration fan exceeds the second preset range, that is, exceeds the normal startup time, it indicates that the heat exchange effect of the second evaporator is not good, and the second evaporator is blocked by frost and fails. Therefore, the defrost condition is directly triggered at this time to perform defrosting, and because the amount of frost on the second evaporator is large, the third delay time is shortened compared with the first delay time, that is, compared with the normal operation of the refrigerator, the second evaporator starts to defrost earlier, thereby ensuring that the first evaporator and the second evaporator can finish defrosting at the same time.

[0063] The first delay time, the second delay time and the third delay time are not further limited here, and it is sufficient to satisfy that under the specific value, after the heater and the refrigeration fan are turned off, the first evaporator and the second evaporator can synchronously end defrosting. Usually, when the first evaporator and the second evaporator synchronously end defrosting, the temperature of the first evaporator is usually around 4°C, and the temperature of the second evaporator is usually around 7°C.

[0064] Optionally, the refrigerator further includes a refrigeration door body, and after determining in step S1003 that the refrigerator meets the second set condition, the method further includes:

[0065] Step S10031: Obtaining the external environment temperature;

[0066] Step S10032: If the ambient temperature is higher than the preset temperature, the refrigeration door is controlled to open for a second delay time. The preset temperature may be 0°C to 10°C, such as 0°C, 2°C, 5°C or 10°C, that is, if the ambient temperature is higher than 10°C, the refrigeration door is not opened to prevent the refrigeration compartment from returning to a high temperature and affecting the preservation effect.

[0067] That is, when the first evaporator corresponding to the refrigerated compartment is blocked by frost and fails, if the ambient temperature is detected to be higher than zero degrees Celsius, the refrigerated door is opened to use the relatively high ambient temperature to accelerate the defrosting speed of the first evaporator. At the same time, since the refrigerated door is only opened for the second delay time, the temperature of the refrigerated compartment only rises slightly, which has little effect on the preservation effect of the refrigerated compartment.

[0068] The specific implementation of opening the refrigeration door is not further limited here. In some examples, the refrigerator may include an alarm module. If the external environment temperature is higher than a preset temperature, the alarm module is controlled to send an alarm message to the user to open the refrigeration door, that is, the refrigeration door is opened by the user. In other examples, the refrigerator may include a hinge structure connecting the refrigeration door and the cabinet. If the external environment temperature is higher than a preset temperature, the hinge structure is controlled to open the refrigeration door. The hinge structure is not further described here.

[0069] Optionally, the refrigerator further includes a freezing door. After determining the target delay time based on the defrosting condition in step S101, the method further includes:

[0070] Step S1011: obtaining a first opening number of the refrigerating door and a second opening number of the freezing door in a refrigeration cycle;

[0071] Step S1012: adjusting the target delay time according to the first opening number and the second opening number.

[0072] Since opening the refrigeration door or the freezer door during the refrigeration cycle will cause outside air to enter the refrigeration compartment or the freezer compartment, and the water content of the outside air is usually greater than the water content in the refrigeration compartment or the freezer compartment, opening the refrigeration door or the freezer door will increase the humidity in the refrigeration compartment or the freezer compartment, thereby increasing the amount of frost on the first evaporator or the second evaporator. Therefore, the target delay time is adjusted according to the first opening number of the refrigeration door and the second opening number of the freezer door to further improve the defrosting coordination of the first evaporator and the second evaporator.

[0073] Optionally, step S1012 adjusts the target delay duration according to the first opening number and the second opening number, including:

[0074] Step S10121: Determine the supplement delay time according to the first opening number;

[0075] Step S10122: Determine the shortened time length according to the second opening times;

[0076] Step S10123: Calculate the difference between the supplementary delay time and the shortened time, and adjust the target delay time according to the difference.

[0077] That is, if the refrigerated door has been opened, the supplementary delay time is increased on the basis of the original target delay time to extend the defrosting time of the first evaporator. If the frozen door has been opened, the shortened time is subtracted from the original target delay time to advance the defrosting time of the second evaporator. The first opening times may be proportional to the supplementary delay time, and the second opening times may be proportional to the shortened time. In some examples, the supplementary delay time may increase by 10 seconds for each increase in the first opening times, and the shortened time may increase by 10 seconds for each increase in the second opening times.

[0078] Optionally, after determining the target delay time based on the defrost condition in step S101, the method further includes:

[0079] Step S1013: Obtaining the external ambient temperature;

[0080] Step S1014: determining an adjustment ratio according to the ambient temperature;

[0081] Step S1015: adjusting the target delay duration based on the adjustment ratio;

[0082] Among them, the ambient temperature is inversely proportional to the adjustment ratio.

[0083] That is, after determining the target delay time according to the operating time of the refrigeration fan and the freezing fan in the refrigeration cycle, the target delay time is further adjusted according to the external ambient temperature. When the external ambient temperature is high, the external ambient temperature basically does not lead to an increase in the amount of frost, so at this time the original target delay time is basically kept unchanged; when the external ambient temperature is low, the external ambient temperature is likely to lead to an increase in the amount of frost, so at this time, on the basis of the original target delay time, the original target delay time is increased by a certain adjustment ratio to obtain the increased target delay time, thereby extending the defrosting time of the first evaporator corresponding to the refrigerated compartment.

[0084] Optionally, after executing step S103 to turn off both the refrigeration fan and the heater, the method further includes:

[0085] Step S104: After the dripping time is preset, the refrigerator is controlled to enter a refrigeration cycle.

[0086] That is, after the first evaporator and the second evaporator have finished defrosting, wait for the preset dripping time to reserve drainage time for the water generated by defrosting, so as to prevent the water formed by defrosting from frosting again in the next refrigeration cycle.
