Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a refrigerator control method, a storage medium and a refrigerator. Background Art

[0002] At present, refrigerators have become an indispensable household appliance in family life. A refrigeration system is set in the refrigerator for refrigeration. The refrigeration system includes an evaporator. After the refrigeration system is used for a period of time, frost will form on the surface of the evaporator. Therefore, in order to ensure the refrigeration effect of the refrigeration system, the evaporator needs to be defrosted regularly. When the evaporator is defrosted, the temperature inside the refrigerator compartment will rise.

[0003] In order to meet the needs of users, some refrigerators are also equipped with ice-making devices. The ice-making device can be installed on the refrigerator body or door body, and the ice-making device can include an ice storage box for storing ice. However, the ice-making device is generally not considered in the defrosting process of current refrigerators, and the defrosting is turned on when the evaporator reaches the defrosting cycle. The temperature rise during the defrosting process often causes the ice in the ice storage box to melt or the ice-making cycle to be extended, which increases the energy consumption of the refrigerator.

[0058] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0059] See also Figure 1 , Figure 2According to an embodiment of the present invention, a refrigerator 100 is provided. The refrigerator 100 may include a housing 110. The storage space formed in the housing 110 may include a refrigerating compartment 111 and a freezing compartment 112. The housing 110 may be connected with a refrigerating door 121 for opening and closing the refrigerating compartment 111 and a freezing door 122 for opening and closing the freezing compartment 112. An ice-making device 150 is installed in the refrigerator 100. An ice-making compartment 113 may be provided on the refrigerating door 121. The ice-making device 150 may be installed inside the ice-making compartment 113. A small ice-making door for opening and closing the ice-making compartment 113 and a dispenser connected to the ice-making compartment 113 may also be installed on the refrigerating door 121. The ice making device 150 may include an ice making tray and an ice storage box 151 placed on the lower side of the ice making tray. The user can open the ice making door to take out the ice storage box 151 inside the ice making chamber 113, or directly take out the ice cubes in the ice storage box 151 through a dispenser without opening the refrigeration door 121 and the ice making door.

[0060] The refrigerator 100 may further include a water supply device for supplying water to the ice tray. When ice making starts, the water supply device injects liquid water into the ice tray. When the liquid water in the ice tray is completely frozen, the ice making device 150 performs an ice turning operation to discharge the ice cubes in the ice tray into the ice storage box 151 for storage. The ice making device 150 may use a flexible ice tray, and realize ice turning by twisting the ice tray. Alternatively, an ice turning structure such as an ice rake 152 may be installed to turn the ice.

[0061] The ice-making device 150 may further include an ice quantity detection component, which can be used to detect the amount of ice in the ice storage box 151. The ice quantity detection component may be an ice detection rod installed on one side of the ice-making tray, or may be an infrared sensor, ultrasonic sensor, pressure sensor, etc. installed in the ice storage box 151 or other locations. The sensor can be used to detect the height or weight of the ice in the ice storage box 151.

[0062] The ice quantity detection component can work according to a predetermined program to detect the ice quantity information in the ice storage box 151. For example, when the water in the ice tray is completely frozen and an ice turning signal is issued, the ice quantity detection component can be controlled to detect the ice quantity information in the ice storage box 151. If the ice quantity information of the ice storage box 151 is not full of ice, the ice making device 150 can be controlled to turn over the ice. If the ice quantity information of the ice storage box 151 is full of ice, the ice making device 150 can be inhibited from turning over the ice. The ice quantity detection component can also detect the ice quantity information in the ice storage box 151 after each ice removal, or detect the ice quantity information in the ice storage box 151 when it is detected that the ice making door is opened and then closed.

[0063] The refrigerator 100 further includes a refrigeration system, which may include a compressor, a condenser, an ice-making evaporator 131, an ice-making capillary tube, an ice-making air return pipe, a cabinet evaporator 141, a cabinet capillary tube, and a cabinet air return pipe. After the refrigerant flowing out of the compressor flows through the condenser, it may flow through the ice-making capillary tube, the ice-making evaporator 131, and the ice-making air return pipe in sequence and then flow back to the compressor to supply cold air to the ice-making compartment 113, or it may flow through the cabinet capillary tube, the cabinet evaporator 141, and the cabinet air return pipe in sequence and then flow back to the compressor to supply cold air to the refrigerating compartment 111 and the freezing compartment 112.

[0064] The refrigerator 100 may also be provided with an ice-making evaporator compartment 130 and a cabinet evaporator compartment 140. The ice-making evaporator 131 may be installed inside the ice-making evaporator compartment 130. The ice-making evaporator compartment 130 may be connected to the ice-making compartment 113 through an air duct. An ice-making fan may be provided inside the ice-making evaporator compartment 130. The operation of the ice-making fan may supply cold air generated by the ice-making evaporator 131 to the inside of the ice-making compartment 113. The cabinet evaporator 141 may be installed inside the cabinet evaporator compartment 140. The cabinet evaporator compartment 140 may be connected to the refrigerating compartment 111 and the freezing compartment 112 to supply cold air to the refrigerating compartment 111 and the freezing compartment 112.

[0065] The ice-making evaporator 131 also has a corresponding defrosting unit, which may include a defrosting heating wire disposed on the ice-making evaporator 131. When there is too much frost on the ice-making evaporator 131 and the defrosting condition of the ice-making evaporator 131 is met, the defrosting heating wire may be turned on to defrost the ice-making evaporator 131. A temperature sensor may also be installed inside the ice-making chamber 113, and the temperature sensor may detect the temperature change inside the ice-making chamber 113.

[0066] See also Figure 3 , is a refrigerator 100 control method provided by the first embodiment of the present invention. The refrigerator 100 control method includes:

[0067] Collect the working parameters of the ice making system;

[0068] When the working parameters meet the preset normal defrosting conditions of the ice-making evaporator 131, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on;

[0069] When it is detected that the ice amount information of the ice storage box 151 is full of ice information, if the working parameters meet the preset full ice defrosting conditions of the ice-making evaporator 131, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on.

[0070] In this embodiment, the ice making system may include an ice making device 150 and a refrigeration system corresponding to the ice making chamber 113, such as a compressor, an ice making evaporator 131, and an ice making fan. When there is too much frost on the ice making evaporator 131, in order not to affect the operation of the ice making evaporator 131, it is necessary to start the defrosting unit corresponding to the ice making evaporator 131 to defrost the ice making evaporator 131.

[0071] When the operating parameters of the ice making system meet the preset normal defrosting conditions, it can be determined that the ice making evaporator 131 needs to be defrosted. At this time, a defrosting instruction can be issued regardless of the amount of ice in the ice storage box 151. The operating parameters of the ice making system may include the cumulative operating time of the compressor after the last defrosting of the ice making evaporator 131 and / or the number of ice making times of the ice making device 150 after the last defrosting of the ice making evaporator 131.

[0072] When it is detected that the ice amount information in the ice storage box 151 is full of ice, at this time, because the amount of ice in the ice storage box 151 is large, the ice cubes in the ice storage box 151 can emit more cold energy, and the temperature rise generated during the defrosting process of the ice-making evaporator 131 will not cause the temperature of the ice-making chamber 113 to be too high, and the impact on the ice cubes in the ice storage box 151 is relatively small. At the same time, when the ice storage box 151 is in a full of ice state, the ice-making device 150 will not perform the ice-turning operation, and therefore, the ice-making device 150 will not immediately start the next ice-making cycle. Defrosting the ice-making evaporator 131 when it is full of ice will not affect the ice-making cycle. Therefore, this is the best time to defrost. If the working parameters of the ice-making system do not meet the preset normal defrosting conditions at this time, it can be determined whether the working parameters of the ice-making system meet the full ice defrosting conditions. If the full ice defrosting conditions are met, the defrost unit corresponding to the ice-making evaporator 131 is controlled to turn on, and the ice-making evaporator 131 is defrosted in the full ice state to minimize the negative impact caused by the defrosting of the ice-making evaporator 131, and at the same time, energy consumption can be saved.

[0073] Furthermore, “the operating parameters satisfy the normal defrosting conditions of the ice-making evaporator 131” may include: the cumulative running time of the compressor after the last defrosting of the ice-making evaporator 131 is greater than or equal to the preset normal defrosting cycle of the ice-making evaporator 131, or the number of ice-making times of the ice-making device 150 is greater than or equal to the preset normal defrosting and ice-making times of the ice-making evaporator 131.

[0074] "The working parameters satisfy the preset full ice defrosting conditions" may include: the cumulative running time of the compressor after the last defrosting of the ice-making evaporator 131 is greater than or equal to the preset full ice defrosting cycle of the ice-making evaporator 131, or the number of ice-making times of the ice-making device 150 is greater than or equal to the preset full ice defrosting number of times.

[0075] The normal defrosting cycle of the ice-making evaporator 131 is greater than the full ice defrosting cycle, and the normal defrosting ice-making times are greater than the full ice defrosting ice-making times.

[0076] Of course, “the working parameters satisfy the normal defrosting condition of the ice-making evaporator 131” may also mean that the cumulative running time of the compressor after the last defrosting of the ice-making evaporator 131 is greater than or equal to the preset normal defrosting cycle of the ice-making evaporator 131, and the number of ice-making times of the ice-making device 150 is greater than or equal to the preset normal defrosting ice-making times of the ice-making evaporator 131. “The working parameters satisfy the preset full ice defrosting condition” may include: the cumulative running time of the compressor after the last defrosting of the ice-making evaporator 131 is greater than or equal to the preset full ice defrosting cycle of the ice-making evaporator 131, and the number of ice-making times of the ice-making device 150 is greater than or equal to the preset full ice defrosting ice-making times.

[0077] For example, if the normal defrosting cycle of the ice-making evaporator 131 is 20 hours, the full ice defrosting cycle can be 15 hours. When it is detected that the cumulative running time of the compressor reaches 20 hours after the last defrosting of the ice-making evaporator 131 is completed, no matter how much ice is in the ice storage box 151, it can be determined that the ice-making evaporator 131 meets the normal defrosting conditions, and the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on. When the ice storage box 151 is full of ice, it can be determined whether the cumulative running time of the compressor is greater than or equal to 15 hours after the last defrosting of the self-made ice evaporator 131 is completed. If so, it can be determined that the ice-making evaporator 131 meets the full ice defrosting conditions, and the defrosting unit corresponding to the ice-making evaporator 131 can be controlled to be turned on in advance to defrost the ice-making evaporator 131.

[0078] If the preset normal defrosting ice making times of the ice-making evaporator 131 is 20 times, the preset full ice defrosting ice making times may be 15 times. When it is detected that the ice-making device 150 has made ice 20 times after the last defrosting, whether the ice storage bucket is in a full ice state or a non-full ice state, it can be determined that the ice-making evaporator 131 meets the normal defrosting conditions, and a defrosting signal for the ice-making evaporator 131 can be sent to control the defrosting unit corresponding to the ice-making evaporator 131 to start, and defrost the ice-making evaporator 131. When the ice quantity information received from the ice storage box 151 is full ice information, it can be determined whether the ice-making times of the ice-making device 150 after the last defrosting of the self-made ice evaporator 131 is greater than or equal to 15 times. If so, it can be determined that the ice-making evaporator 131 has met the full ice defrosting conditions, and a defrosting signal for the ice-making evaporator 131 can be sent to control the defrosting unit corresponding to the ice-making evaporator 131 to start in advance, and start defrosting the ice-making evaporator 131.

[0079] In this way, when the ice storage box 151 is full of ice, the ice-making evaporator 131 can be defrosted in advance, thereby minimizing the negative impact of defrosting the ice-making evaporator 131 and reducing the temperature rise of the ice-making chamber 113 caused by defrosting the ice-making evaporator 131, saving energy and reducing the risk of melting of ice cubes in the ice storage box 151.

[0080] like Figure 4 FIG. 1 is a control method for a refrigerator 100 according to a second embodiment of the present invention. The control method for a refrigerator 100 includes:

[0081] Collect the working parameters of the ice making system;

[0082] When the working parameters meet the preset normal defrosting conditions of the ice-making evaporator 131, it is determined whether the ice-making compartment 113 needs to be precooled according to the ice quantity information of the ice storage box 151;

[0083] If the ice-making chamber 113 needs to be precooled, the refrigeration system is controlled to cool the ice-making chamber 113, and when the temperature of the ice-making chamber 113 is monitored to be equal to or lower than the preset precooling temperature, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on;

[0084] If the ice-making chamber 113 does not need to be pre-cooled, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on;

[0085] When it is detected that the ice amount information of the ice storage box 151 is full of ice information, if the working parameters meet the preset full ice defrosting conditions of the ice-making evaporator 131, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on.

[0086] The refrigerator control method of this embodiment is a further improvement of the refrigerator control method of the first embodiment. The difference between the refrigerator 100 control method of this embodiment and the refrigerator 100 control method of the first embodiment is that when the working parameters of the ice-making system meet the normal defrosting conditions of the preset ice-making evaporator 131, it is determined whether to pre-cool the ice-making chamber 113 according to the ice quantity information of the ice storage box 151. If the ice-making chamber 113 needs to be pre-cooled, the refrigeration system is controlled to start refrigerating the ice-making chamber 113. When the temperature of the ice-making chamber 113 reaches the corresponding pre-cooling temperature, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to start. In this way, it can be avoided that the defrosting of the ice-making evaporator 131 causes the temperature of the ice-making chamber 113 to be too high, the ice cubes in the ice storage box 151 melt, or the ice-making cycle of the ice-making device 150 is too long.

[0087] The precooling temperature may be a fixed temperature or may be changed according to parameters affecting the temperature of the ice-making compartment, such as the working condition of the ice-making device 150 . The precooling temperature may be pre-stored in the memory of the refrigerator 100 .

[0088] For example, when the working parameters of the ice-making system meet the defrosting conditions of the ice-making evaporator 131, if the ice-making chamber needs to be pre-cooled, the pre-cooling temperature corresponding to the ice-making chamber 113 can be obtained first, and the temperature of the ice-making chamber 113 can be monitored. For example, the temperature sensor in the ice-making chamber 113 can be controlled to detect the temperature of the ice-making chamber 113. Of course, the temperature sensor in the ice-making chamber 113 can periodically detect the temperature in the ice-making chamber 113 and upload and store the detected temperature in the memory of the refrigerator 100. When the working parameters of the ice-making system meet the defrosting conditions of the ice-making evaporator 131, the stored temperature of the ice-making chamber 113 can be directly called.

[0089] If the precooling temperature is -8°C and the current temperature of the ice-making chamber 113 is -3°C, the refrigeration system is controlled to refrigerate the ice-making chamber 113. When the temperature of the ice-making chamber 113 drops to the precooling temperature -8°C, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on to defrost the ice-making evaporator 131. Of course, if the current temperature of the ice-making chamber 113 is lower than -8°C, such as -9°C, there is no need to refrigerate the ice-making chamber 113, and the defrosting unit corresponding to the ice-making evaporator 131 can be directly turned on.

[0090] In this way, when the temperature of the ice making chamber 113 is -8°C, the ice making evaporator 131 is defrosted. If the temperature of the ice making chamber 113 rises by 5°C during the defrosting process, then after the ice making evaporator 131 is defrosted, the temperature of the ice making chamber 113 is still -3°C.

[0091] In this way, even if the temperature of the ice making chamber 113 rises during the defrosting process of the ice making evaporator 131, the temperature of the ice making chamber 113 will not be too high, and will not affect the ice cubes stored in the ice bank 151 and the subsequent ice making process.

[0092] In one embodiment, “determining whether to precool the ice making chamber 113 according to the ice quantity information of the ice storage box 151” includes:

[0093] If the amount of ice in the ice storage box 151 is greater than or equal to the first preset value, there is no need to precool the ice making chamber 113;

[0094] If the amount of ice in the ice storage box 151 is less than the first preset value, the ice making chamber 113 needs to be precooled.

[0095] When the amount of ice in the ice storage box 151 is greater than the first preset value, the amount of ice in the ice storage box 151 is relatively large. At this time, the temperature rise generated during the defrosting process of the ice-making evaporator 131 will not cause the temperature of the ice-making chamber 113 to rise too much, nor will it cause the ice cubes in the ice storage box 151 to melt. In this way, when the amount of ice in the ice storage box 151 is relatively large, since the defrosting of the ice-making evaporator 131 has little effect on the temperature of the ice-making chamber 113, the defrosting unit can be directly turned on for defrosting without pre-cooling, which further saves energy consumption and avoids the noise caused by the compressor during the pre-cooling process.

[0096] In another embodiment, “determining whether the ice making chamber 113 needs to be precooled according to the ice quantity information of the ice storage box 151” includes:

[0097] If the ice quantity information of the ice storage box is not full of ice information, it is not necessary to precool the ice making chamber 113;

[0098] If the ice amount information of the ice storage box is full of ice information, the ice making chamber 113 needs to be precooled.

[0099] For further information, see Figure 7 In this embodiment, the refrigerator 100 control method further includes:

[0100] If the ice making chamber 113 needs to be pre-cooled, the corresponding pre-cooling temperature is matched according to the ice quantity information.

[0101] Among them, the memory of the refrigerator 100 may store an ice quantity information-precooling temperature comparison table. The precooling temperature may be positively correlated with the ice quantity in the ice storage box 151. The more ice there is in the ice storage box 151, the more cold energy the ice cubes can release, and the smaller the temperature rise of the ice making chamber 113 during the defrosting process of the ice making evaporator 131. Therefore, the matching precooling temperature can be higher.

[0102] For example, if the full amount of ice in the ice storage box 151 is Q, if the current temperature of the ice-making chamber 113 is -3°C, if the current amount of ice in the ice storage box 151 is Q, then the defrosting process of the ice-making evaporator 131 may cause the temperature of the ice-making chamber 113 to rise by 2°C. After the defrosting is completed, the temperature of the ice-making chamber 113 is -1°C, and the ice cubes in the ice storage box 151 will not melt. Therefore, there is no need to pre-cool the ice-making chamber to defrost. If the current amount of ice in the ice storage box 151 is 0.8Q, the temperature of the ice-making chamber 113 may rise by 4°C during the defrosting process of the ice-making evaporator 131. At this time, the ice-making chamber 113 needs to be pre-cooled before defrosting, and the pre-cooling temperature may be -5°C. When the amount of ice in the ice storage box 151 is 0.6Q, the defrosting of the ice-making evaporator 131 may cause the temperature of the ice-making chamber 113 to rise by 6°C. Therefore, the corresponding pre-cooling temperature may be -7°C. In this way, it can be ensured that the temperature of the ice-making chamber 113 is below 0°C after the defrosting of the ice-making evaporator 131 is completed, the ice cubes in the ice storage box 151 will not melt, and will not affect the ice-making device from making ice after the defrosting is completed.

[0103] In this embodiment, “matching the corresponding pre-cooling temperature according to ice quantity information” may include:

[0104] If the current ice amount is greater than or equal to the second preset value, the precooling temperature is the first precooling temperature;

[0105] Otherwise, the precooling temperature is the second precooling temperature;

[0106] Among them, the second preset value is smaller than the first preset value, and the second pre-cooling temperature is smaller than the first pre-cooling temperature.

[0107] For example, if the full ice amount of the ice storage box 151 is Q, the first preset value may be 0.8Q, and the second preset value may be 0.5Q. When the current amount of ice in the ice storage box 151 is greater than or equal to the first preset value 0.8Q, there is no need to pre-cool the ice-making chamber 113, and the defrosting unit corresponding to the ice-making evaporator 131 may be directly turned on to defrost the ice-making evaporator 131. When the current amount of ice in the ice storage box 151 is less than the first preset value 0.8Q and greater than or equal to the second preset value 0.5Q, the pre-cooling temperature corresponding to the ice-making chamber 113 may be T1. At this time, if the temperature of the ice-making chamber 113 is greater than T1, the refrigeration system may be turned on first to pre-cool the ice-making chamber 113. When the temperature of the ice-making chamber 113 drops to T1, the defrost unit corresponding to the ice-making evaporator 131 is controlled to be turned on to defrost the ice-making evaporator 131; if the current amount of ice in the ice storage box 151 is less than the second preset value 0.5Q, the pre-cooling temperature corresponding to the ice-making chamber 113 may be T2, and T2 is less than T1 to ensure that the ice cubes in the ice storage box 151 in the ice-making chamber 113 are not affected. At this time, if the temperature of the ice-making chamber 113 is greater than T2, the refrigeration system may be turned on first to pre-cool the ice-making chamber 113. When the temperature of the ice-making chamber 113 drops to T2, the defrost unit corresponding to the ice-making evaporator 131 is controlled to be turned on to defrost the ice-making evaporator 131.

[0108] In this way, it is possible to determine whether to pre-cool the ice-making chamber 113 and match the appropriate pre-cooling temperature based on the current amount of ice in the ice storage box 151, thereby reducing energy consumption and improving defrosting efficiency, avoiding the negative impact of excessively high temperature in the ice-making chamber 113 on the ice-making device 150, and at the same time being able to reasonably control the pre-cooling operation, avoid excessive pre-cooling, and reduce energy consumption.

[0109] See also Figure 6 , is a refrigerator 100 control method according to a third embodiment of the present invention. The refrigerator 100 control method includes:

[0110] Collect the working parameters of the ice making system;

[0111] When the working parameters meet the preset normal defrosting conditions of the ice-making evaporator 131, or when the ice amount in the ice storage box 151 is detected to be full of ice and the working parameters meet the preset full ice defrosting conditions of the ice-making evaporator 131, the refrigeration system is controlled to refrigerate the ice-making compartment 113;

[0112] When the temperature of the ice-making compartment 113 reaches the pre-cooling temperature, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on.

[0113] The control method of the refrigerator 100 of this embodiment is different from the control method of the refrigerator 100 of the second embodiment in that when the ice storage box 151 is full of ice, the refrigeration system is first controlled to cool the ice-making chamber 113 to the pre-cooling temperature, and then the defrosting unit corresponding to the ice-making evaporator 131 is controlled to start defrosting. In this way, the temperature of the ice-making chamber 113 is too high in the full ice state due to abnormal conditions. For example, in the full ice state, the user opens the refrigeration door 121 or the ice-making small door for a long time, resulting in the ice-making chamber 113 The temperature is too high, at this time, if it is detected that the ice-making evaporator 131 meets the full ice defrosting condition, directly opening its corresponding defrosting unit to defrost the ice-making evaporator 131 may cause the temperature in the ice-making chamber 113 to further increase, and the ice in the ice storage box 151 melts. Therefore, when the ice-making chamber 113 is full of ice, it can be pre-cooled and then the defrosting unit corresponding to the ice-making evaporator 131 can be controlled to start.

[0114] For further information, see Figure 7 In this embodiment, the refrigerator 100 control method further includes:

[0115] The corresponding pre-cooling temperature is matched according to the ice quantity information of the ice storage box 151.

[0116] The pre-cooling temperature may be positively correlated with the current amount of ice in the ice storage box 151 . The more the current amount of ice in the ice storage box 151 , the higher the corresponding pre-cooling temperature may be.

[0117] Specifically, if the ice storage box 151 is full of ice with an amount of Q, the pre-cooling temperature can be T1 when the ice storage box 151 is full of ice; when the ice storage box 151 is not full of ice, if it is greater than or equal to a preset value, such as greater than or equal to 0.5Q, the corresponding pre-cooling temperature is T2; when the ice storage box 151 is less than the preset value, such as less than 0.5Q, the corresponding pre-cooling temperature is T3, wherein T1 is greater than T2, and T2 is greater than T3.

[0118] If the temperature of the ice-making chamber 113 is less than or equal to the corresponding pre-cooling temperature, the defrost unit corresponding to the ice-making evaporator 131 can be directly turned on. If the temperature of the ice-making chamber 113 is greater than the corresponding pre-cooling temperature, the refrigeration system is turned on to cool the ice-making chamber 113 until the temperature of the ice-making chamber 113 reaches the corresponding pre-cooling temperature, and then the defrost unit corresponding to the ice-making evaporator 131 is controlled to turn on.

[0119] In this way, the precooling temperature can be controlled according to the amount of ice in the ice storage box 151, which can prevent inadequate precooling or over-precooling, and can avoid the temperature in the ice storage box 151 being too low, while saving energy consumption.

[0120] See also Figure 8In one embodiment of the present invention, a refrigerator 100 is provided, comprising a memory 102 and a processor 101, wherein the memory 102 and the processor 101 are connected to each other through a communication bus 104. The memory 102 stores a computer program that can be run on the processor 101, and when the processor 101 executes the computer program, the steps in the refrigerator control method in the above embodiment are implemented. The refrigerator 100 also includes a communication interface 103 connected to the communication bus 104, which is used to communicate with other devices in the refrigerator 100.

[0121] An embodiment of the present invention further provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps in the refrigerator control method in the above embodiment are implemented.

[0122] Therefore, in summary, the refrigerator control method provided by the present invention, when the ice storage box is in a full ice state, actively determines whether the working parameters of the ice-making system meet the full ice defrosting conditions. If the conditions are met, the ice-making evaporator is defrosted in advance in the full ice state. In this way, the impact of defrosting the ice-making evaporator can be minimized and energy consumption can be saved at the same time.
