[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 an ice-making device. 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 during the defrosting process of current refrigerators, and the temperature rise during the defrosting process often causes the ice cubes in the ice storage box to melt. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a refrigerator control method, a storage medium and a refrigerator, which control the precooling of the ice-making compartment according to the ice amount information in the ice storage box.

[0012] Determining whether the current amount of ice in the ice storage box is less than a first preset value;

[0013] If yes, it is necessary to precool the ice-making compartment;

[0014] If not, there is no need to precool the ice making compartment.

[0015] As a further improvement of an embodiment of the present invention, the first preset value is the full ice amount of the ice storage box.

[0016] As a further improvement of an embodiment of the present invention, the precooling temperature is positively correlated with the current ice amount.

[0017] As a further improvement of an embodiment of the present invention, “matching the corresponding precooling temperature according to the ice amount information” includes:

[0018] If the current ice amount is greater than or equal to the second preset value, the precooling temperature is the first precooling temperature;

[0019] Otherwise, the precooling temperature is the second precooling temperature;

[0020] 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.

[0021] In order to achieve one of the above-mentioned purposes of the invention, another embodiment of the present invention also provides a refrigerator control method, comprising:

[0022] When the defrosting conditions for the ice-making evaporator are met, the corresponding pre-cooling temperature is matched according to the ice quantity information of the ice storage box;

[0023] Control the refrigeration system to cool the ice-making room and monitor the temperature of the ice-making room;

[0024] When the temperature of the ice-making compartment reaches the corresponding pre-cooling temperature, a start signal is sent to the defrosting unit corresponding to the ice-making evaporator.

[0025] As a further improvement of an embodiment of the present invention, the current amount of ice in the ice storage box is positively correlated with the precooling temperature.

[0026] As a further improvement of an embodiment of the present invention, “matching the corresponding precooling temperature according to the ice amount information” includes:

[0027] If the current ice amount is greater than or equal to the preset value, the precooling temperature is the first precooling temperature;

[0028] Otherwise, the precooling temperature is the second precooling temperature, and the first precooling temperature is greater than the second precooling temperature.

[0031] The refrigerator control method provided by the present invention controls the pre-cooling operation of the refrigeration system on the ice-making compartment according to the ice amount information in the ice storage box. When the amount of ice in the ice storage box is large, a higher pre-cooling temperature is matched, or the ice-making compartment is directly defrosted without pre-cooling the ice-making compartment. When the amount of ice in the ice storage box is small, a lower pre-cooling temperature is matched. In this way, it can be avoided that the ice cubes in the ice storage box are melted due to defrosting of the ice-making evaporator. At the same time, energy consumption can be saved and the defrosting efficiency can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] 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.

[0040] See also Figure 1 , Figure 2 According 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.

[0041] 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.

[0042] The ice-making device 150 may also 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 can be an ice detection rod installed on one side of the ice making tray, or it can be an infrared sensor, ultrasonic sensor, pressure sensor, etc. installed in the ice storage box 151 or other positions. The sensor can be used to detect the height, weight or quantity of ice in the ice storage box 151.

[0043] 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.

[0044] 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. The refrigerant flowing out of the compressor flows through the condenser, and then flows through the ice-making capillary tube, the ice-making evaporator 131, and the ice-making air return pipe in sequence before flowing back to the compressor, or flows through the cabinet capillary tube, the cabinet evaporator 141, and the cabinet air return pipe in sequence before flowing back to the compressor.

[0045] 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.

[0046] 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.

[0047] See also Figure 3 , is a refrigerator 100 control method according to a first embodiment of the present invention, and the refrigerator 100 control method includes:

[0048] When the defrosting conditions for the ice-making evaporator 131 are met, it is determined whether to pre-cool the ice-making compartment 113 according to the current ice quantity information of the ice storage box 151;

[0049] If the ice-making chamber 113 needs to be precooled, the refrigeration system is controlled to refrigerate the ice-making chamber 113, and when it is detected that the temperature of the ice-making chamber 113 reaches the corresponding precooling temperature, a start signal is sent to the defrosting unit corresponding to the ice-making evaporator 131;

[0050] If the ice-making compartment 113 does not need to be pre-cooled, a start signal is sent to the defrosting unit corresponding to the ice-making evaporator 131 .

[0051] In this embodiment, satisfying the defrosting condition for the ice-making evaporator 131 may include satisfying the normal defrosting condition or the abnormal defrosting condition for the ice-making evaporator 131. Among them, satisfying the normal defrosting condition for the ice-making evaporator 131 may include: the cumulative running time of the compressor after the last defrosting of the ice-making evaporator 131 reaches the preset defrosting cycle of the ice-making evaporator 131, or the number of ice-making times of the ice-making device 150 reaches the preset number of defrosting and ice-making times of the ice-making evaporator 131. Satisfying the abnormal defrosting condition for the ice-making evaporator 131 may include that the temperature of the ice-making evaporator compartment 130 is less than the preset value, or it is detected that the current of the ice-making fan is greater than the preset value and the speed is less than the preset value. At this time, it can be determined that the ice-making evaporator 131 or the ice-making fan is blocked by ice, and the ice-making evaporator 131 needs to be defrosted.

[0052] In this embodiment, since the temperature of the ice-making chamber 113 will rise during the defrosting process of the ice-making evaporator 131, it may have a negative impact on the ice-making device 150. For example, when the temperature of the ice-making chamber 113 is higher than zero degrees, the ice cubes in the ice storage box 151 may melt. After the defrosting is completed, the liquid water melted from the ice cubes in the ice storage box 151 freezes, causing the ice cubes in the ice storage box 151 to stick together and form ice lumps. Therefore, in order to reduce the impact of the defrosting of the ice-making evaporator 131 on the temperature of the ice-making chamber 113, the refrigeration system may be controlled to pre-cool the ice-making chamber 113 before the ice-making evaporator 131 is defrosted to reduce the temperature of the ice-making chamber 113. When the temperature in the ice-making chamber 113 reaches the pre-cooling temperature, the ice-making evaporator 131 is defrosted. 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 will not be too high.

[0053] The precooling temperature may be a preset fixed temperature, or a temperature that varies according to other parameters that affect the temperature of the ice-making compartment.

[0054] For example, if the pre-cooling temperature is -10°C, the refrigeration system can be controlled to quickly cool the ice-making chamber 113 before the ice-making evaporator 131 is defrosted, so that the temperature of the ice-making chamber 113 is reduced to -10°C. In this way, even if the temperature rises during the defrosting process of the ice-making evaporator 131, such as the defrosting of the ice-making evaporator causes the temperature of the ice-making chamber to rise by 5°C, then the temperature of the ice-making chamber will still be -5°C after the defrosting is completed, which will not affect the ice cubes in the ice storage box 151.

[0055] The more ice there is in the ice storage box 151, the more cold energy the ice cubes can emit, and the smaller the temperature rise of the ice making chamber 113 during the defrosting process of the ice making evaporator 131. When the amount of ice in the ice storage box 151 is greater than a certain amount, the temperature generated by the ice making evaporator 131 during the defrosting process may not cause the temperature of the ice making chamber 113 to be too high. Therefore, it is possible to first determine whether the ice making chamber 113 needs to be pre-cooled based on the ice amount information in the ice storage box 151. In this way, the pre-cooling time can be reduced, the noise generated by the compressor during the pre-cooling process can be avoided, and the defrosting efficiency can be improved to save energy.

[0056] See also Figure 4 In this embodiment, the control method of the refrigerator 100, "determining whether to pre-cool the ice-making compartment 113 according to the current ice quantity information of the ice storage box 151" includes:

[0057] Determine whether the current amount of ice in the ice storage box 151 is less than a first preset value;

[0058] If yes, the ice making chamber 113 needs to be precooled;

[0059] If not, there is no need to pre-cool the ice making chamber 113 .

[0060] In this embodiment, the first preset value may be the full ice quantity Q of the ice storage box 151, or any other suitable ice quantity, and the first preset value may be greater than 0.5 Q. When the ice quantity of the ice storage box 151 is greater than the first preset value, the ice quantity 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. Therefore, it is not necessary to precool the ice-making chamber 113, and the defrosting unit corresponding to the ice-making evaporator 131 can be directly turned on to defrost the ice-making evaporator 131, thereby saving energy consumption.

[0061] Furthermore, in this embodiment, the refrigerator control method further includes:

[0062] If the ice making compartment needs to be precooled, the corresponding precooling temperature is matched according to the ice quantity information.

[0063] The temperature rise of the ice-making compartment during the defrosting process of the ice-making evaporator is related to the amount of ice in the ice storage box. The more ice there is in the ice storage box, the more cold air the ice cubes can emit, and the smaller the temperature rise of the ice-making compartment. Therefore, the corresponding pre-cooling temperature can be matched according to the ice amount information of the ice storage box to save energy and avoid insufficient or excessive pre-cooling.

[0064] Furthermore, in this embodiment, the precooling temperature is positively correlated with the current ice amount.

[0065] “Matching the corresponding pre-cooling temperature according to ice quantity information” may include:

[0066] If the current ice amount is greater than or equal to the second preset value, the precooling temperature is the first precooling temperature;

[0067] Otherwise, the precooling temperature is the second precooling temperature;

[0068] 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.

[0069] In this embodiment, the more ice there is in the ice storage box 151, the smaller the temperature rise of the ice making chamber 113 during the defrosting process of the ice making evaporator 131, and therefore, the precooling temperature corresponding to the ice making chamber 113 can be higher.

[0070] 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.

[0071] In this way, it can be determined whether to pre-cool the ice-making compartment and match the appropriate pre-cooling temperature according to the current amount of ice in the ice storage box 151, thereby reducing energy consumption and improving defrosting efficiency.

[0072] See also Figure 5 , which is a refrigerator 100 control method according to a second embodiment of the present invention, and the refrigerator 100 control method includes:

[0073] When the defrosting conditions for the ice-making evaporator 131 are met, the corresponding pre-cooling temperature is matched according to the ice quantity information of the ice storage box 151;

[0074] Controlling the refrigeration system to cool the ice-making chamber 113 and monitoring the temperature of the ice-making chamber 113;

[0075] When the temperature of the ice-making compartment 113 reaches the corresponding pre-cooling temperature, a start signal is sent to the defrosting unit corresponding to the ice-making evaporator 131 .

[0076] Compared with the refrigerator 100 control method of the first embodiment, the present embodiment is different from the refrigerator 100 control method of the present embodiment in that the refrigerator 100 control method of the present embodiment directly matches the corresponding pre-cooling temperature according to the current ice amount information of the ice storage box 151. Even if the ice storage box 151 is currently full of ice, the defrost unit corresponding to the ice-making evaporator 131 is turned on after the ice-making chamber 113 is pre-cooled.

[0077] After matching the corresponding precooling temperature according to the ice quantity information, it can be determined whether to defrost the ice-making evaporator 131 according to whether the temperature of the ice-making chamber 113 reaches the precooling temperature. In this way, the impact of defrosting the ice-making evaporator 131 on the ice-making chamber 113 can be further reduced to avoid abnormal or special situations.

[0078] If the user opens the refrigeration door 121 for a long time or forgets to close the refrigeration door 121 before defrosting, or the user opens the ice-making door on the ice-making chamber 113 for a long time, the temperature inside the ice-making chamber 113 is too high. At this time, the amount of ice in the ice storage box 151 may be large. However, if the ice-making chamber 113 is not precooled and the defrosting unit is directly turned on to defrost the ice-making evaporator 131, the temperature of the ice-making chamber 113 will continue to rise. Therefore, in this embodiment, no matter how much ice is in the ice storage box 151, the corresponding precooling temperature is first obtained according to the amount of ice, and the ice-making evaporator 131 is defrosted when the temperature of the ice-making chamber 113 reaches the precooling temperature.

[0079] In this embodiment, the precooling temperature is 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 is, the higher the precooling temperature of the corresponding ice-making compartment 113 is.

[0080] For further information, see Figure 6 , the control method of the refrigerator 100 "matching the corresponding pre-cooling temperature according to the ice quantity information" includes:

[0081] If the current amount of ice in the ice storage box 151 is greater than or equal to the preset value, the precooling temperature is the first precooling temperature;

[0082] Otherwise, the precooling temperature is a second precooling temperature, wherein the first precooling temperature is greater than the second precooling temperature.

[0083] As a specific example, if the full ice amount of the ice storage box 151 is Q, the preset value may be 0.5Q. When the current ice amount of the ice storage box 151 is greater than or equal to 0.5Q, the first precooling temperature T1 may be matched, and the current temperature of the ice-making chamber 113 may be obtained. If the current temperature of the ice-making chamber 113 is greater than T1, the refrigeration system may be turned on to precool the ice-making chamber 113 until the temperature of the ice-making chamber 113 drops to T1. Then, the defrost unit corresponding to the ice-making evaporator 131 may be turned on to defrost the ice-making evaporator 131. When the current amount of ice in the ice storage box 151 is less than 0.5Q, the second precooling temperature T2 can be matched. Since the amount of ice in the ice storage box 151 is small, the second precooling temperature T2 can be lower than the first precooling temperature T1. If the temperature of the ice-making chamber 113 is greater than T2 at this time, the ice-making system can be turned on to precool the ice-making chamber 113. When the temperature of the ice-making chamber 113 drops to T2, the defrosting unit corresponding to the ice-making evaporator 131 can be turned on to defrost the ice-making evaporator 131.

[0084] In this way, the pre-cooling temperature of the ice-making chamber 113 is directly matched according to the ice quantity information, and the ice-making evaporator 131 is defrosted when it is confirmed that the temperature of the ice-making chamber 113 reaches the pre-cooling temperature. This can avoid the negative impact of excessively high temperature of the ice-making chamber 113 on the ice-making device 150, and at the same time can reasonably control the pre-cooling operation, avoid excessive pre-cooling, and reduce energy consumption.

[0085] See also Figure 7 In 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.

[0086] 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.

[0087] Therefore, in summary, the refrigerator control method and refrigerator 100 provided by the present invention, when the ice-making evaporator 131 meets the defrosting conditions, first obtain the ice amount information in the ice storage box 151, and control the pre-cooling of the ice-making chamber 113 according to the ice amount information. When the amount of ice is large, it is possible to choose not to pre-cool the ice-making chamber 113, or to set a high pre-cooling temperature for the ice-making chamber 113. When the amount of ice is small, a low pre-cooling temperature can be used. In this way, the melting of ice cubes in the ice storage box 151 during the defrosting process of the ice-making evaporator 131 can be avoided, and at the same time, the defrosting efficiency can be improved and energy consumption can be saved.
