For example, when the water in the ice making tray is completely frozen and an ice turning signal is sent, the ice volume detection component can be controlled to detect the ice volume information in the ice storage box 151, and if the ice volume information of the ice storage box 151 is not full of ice, then it can be The ice making device 150 is controlled to turn over ice, and if the ice volume information of the ice storage box 151 is full of ice, the ice making device 150 can be prevented from turning over ice. The ice amount detection component can also detect the ice amount information in the ice storage box 151 after each ice extraction is completed, or detect the ice amount information in the ice storage box 151 when the small ice making door is detected to be opened and then closed.

The refrigerator 100 also includes a refrigeration system, which may include a compressor, a condenser, an ice-making evaporator 131 , an ice-making capillary, an ice-making return air pipe, a box evaporator 141 , a box capillary, and a box return air pipe.

The air return pipe of the box body flows back to the compressor.

The refrigerator 100 can also be provided with an ice-making evaporator compartment 130 and a box evaporator compartment 140. The ice-making evaporator 131 can be installed inside the ice-making evaporator compartment 130, and the ice-making evaporator compartment 130 can be blown by the wind. The channel communicates with the ice-making compartment 113 , and an ice-making fan can be installed inside the ice-making evaporator compartment 130 , and the ice-making fan can supply cold air generated by the ice-making evaporator 131 to the interior of the ice-making compartment 113 .

The ice-making evaporator 131 also has a corresponding defrosting unit. The defrosting unit may include a defrosting heating wire arranged on the ice-making evaporator 131. In the defrosting condition, the defrosting heating wire can be turned on to defrost the ice-making evaporator 131 . A temperature sensor can also be installed inside the ice-making compartment 113 , and the temperature sensor can detect the temperature change inside the ice-making compartment 113 .

Referring to FIG. 3 , it is a control method of a refrigerator 100 according to the first embodiment of the present invention, and the control method of the refrigerator 100 includes:

When the defrosting condition for the ice-making evaporator 131 is satisfied, it is judged whether to pre-cool the ice-making compartment 113 according to the current ice volume information of the ice storage box 151;

If it is necessary to pre-cool the ice-making compartment 113, then control the refrigeration system to refrigerate the ice-making compartment 113, and when it is detected that the temperature of the ice-making compartment 113 reaches the corresponding pre-cooling temperature, the ice-making evaporator 131 corresponding The defrosting unit sends a start signal;

If there is no need to pre-cool the ice-making compartment 113 , an activation signal is sent to the defrosting unit corresponding to the ice-making evaporator 131 .

In this embodiment, satisfying the defrosting condition for the ice-making evaporator 131 may include satisfying a normal defrosting condition or an abnormal defrosting condition for the ice-making evaporator 131 . Wherein, satisfying the normal defrosting conditions of the ice-making evaporator 131 may include: after the last defrosting of the ice-making evaporator 131, the accumulated running time of the compressor reaches the preset defrosting cycle of the ice-making evaporator 131, or the ice-making device 150 The number of times of ice making reaches the preset number of times of defrosting and ice making of the ice making evaporator 131. The ice-making evaporator 131 meeting the abnormal defrosting condition may include that the temperature of the ice-making evaporator compartment 130 is lower 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 lower than the preset value. At this time, it can be determined that If the ice-making evaporator 131 or the ice-making fan is blocked by ice, it is necessary to defrost the ice-making evaporator 131 .

In this embodiment, since the temperature of the ice-making compartment 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 compartment 113 is higher than zero , may cause the ice cubes in the ice storage box 151 to melt. After defrosting, the liquid water produced by the melting of the ice cubes in the ice storage box 151 will freeze, which will cause the ice cubes in the ice storage box 151 to stick together and form ice lumps. . Therefore, in order to reduce the impact of defrosting the ice-making evaporator 131 on the temperature of the ice-making compartment 113, the refrigeration system can be controlled to pre-cool the ice-making compartment 113 before defrosting the ice-making evaporator 131, reducing the temperature of the ice-making compartment. 113, when the temperature in the ice-making compartment 113 reaches the pre-cooling temperature, the ice-making evaporator 131 is defrosted. The temperature will not be too high.

The pre-cooling temperature can be a preset fixed temperature, or a temperature that changes according to other parameters that affect the temperature of the ice-making compartment.

For example, if the pre-cooling temperature is -10°C, before defrosting the ice-making evaporator 131, the refrigeration system can be controlled to quickly cool the ice-making compartment 113, and the temperature of the ice-making compartment 113 can be reduced to - 10°C, so, even if the temperature rises during the defrosting process of the ice-making evaporator 131, if the defrosting of the ice-making evaporator causes the temperature of the ice-making compartment to rise by 5°C, the temperature of the ice-making compartment will remain the same after the end of defrosting. The temperature is -5°C, which will not affect the ice cubes in the ice storage box 151 .

Because the more ice in the ice storage box 151, the more cold the ice cubes can dissipate, the smaller the temperature rise of the ice-making compartment 113 during the defrosting process of the ice-making evaporator 131 is. When the amount of ice is greater than a certain amount, the temperature generated during the defrosting process of the ice-making evaporator 131 may not cause the temperature of the ice-making compartment 113 to be too high. The ice-making compartment 113 needs to be pre-cooled. 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 consumption.

Referring to Fig. 4 , in this embodiment, in the control method of the refrigerator 100, "judging whether to pre-cool the ice-making compartment 113 according to the current ice volume information of the ice storage box 151" includes:

Judging whether the current ice volume of the ice storage box 151 is less than a first preset value;

If so, it is necessary to pre-cool the ice-making compartment 113;

If not, there is no need to pre-cool the ice-making compartment 113 .

In this embodiment, the first preset value may be the full ice volume Q of the ice storage bin 151 , or any other suitable ice volume, and the first preset value may be greater than 0.5Q. 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 make the ice-making compartment If the temperature of 113 rises too much, it will not cause the ice cubes in the ice storage box 151 to melt. Therefore, it is not necessary to pre-cool the ice-making compartment 113, and the defrosting unit corresponding to the ice-making evaporator 131 can be directly opened to make ice. The evaporator 131 performs defrosting, thereby saving energy consumption.

Further, in this implementation manner, the refrigerator control method further includes:

If the ice-making compartment needs to be pre-cooled, the corresponding pre-cooling temperature is matched according to the ice volume information.

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 in the ice storage box, the more cold the ice cubes can dissipate. The temperature of the ice-making compartment The smaller the rise, therefore, the corresponding pre-cooling temperature can be matched according to the ice volume information of the ice storage box, so as to save energy consumption and avoid insufficient pre-cooling or excessive pre-cooling.

Furthermore, in this embodiment, the pre-cooling temperature is positively correlated with the current amount of ice.

"Matching the corresponding pre-cooling temperature based on ice volume information" may include:

Otherwise, the pre-cooling temperature is the second pre-cooling temperature;

In this embodiment, the greater the current amount of ice in the ice storage box 151, the smaller the temperature rise of the ice-making compartment 113 during the defrosting process of the ice-making evaporator 131. Therefore, the corresponding precooling temperature of the ice-making compartment 113 can be higher.

For example, if the ice storage bin 151 is full of ice and the ice volume is Q, the first preset value can be 0.8Q, and the second preset value can be 0.5Q. When the current ice volume in the ice storage bin 151 is greater than or equal to When the first preset value is 0.8Q, there is no need to pre-cool the ice-making compartment 113, and the defrosting unit corresponding to the ice-making evaporator 131 can be directly turned on to defrost the ice-making evaporator 131; When the amount of ice is less than the first preset value 0.8Q and greater than or equal to the second preset value 0.5Q, the corresponding precooling temperature of the ice making compartment 113 can be T1. At this time, if the temperature of the ice making compartment 113 is greater than T1, then the refrigeration system can be turned on first to pre-cool the ice-making compartment 113, and when the temperature of the ice-making compartment 113 drops to T1, then the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on for the ice-making evaporator 131 Perform defrosting; if the current ice volume of the ice storage box 151 is less than the second preset value of 0.5Q, then the corresponding precooling temperature of the ice making compartment 113 can be T2, and T2 is less than T1 to ensure that the ice making compartment 113 The ice cubes in the ice storage box 151 will not be affected. At this time, if the temperature of the ice-making compartment 113 is greater than T2, the refrigeration system can be turned on to pre-cool the ice-making compartment 113. When the temperature of the ice-making compartment 113 When the temperature decreases to T2, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on to defrost the ice-making evaporator 131 .

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

Referring to Fig. 5, it is a control method of refrigerator 100 according to the second embodiment of the present invention, and the control method of refrigerator 100 includes:

When the defrosting conditions for the ice-making evaporator 131 are met, match the corresponding pre-cooling temperature according to the ice volume information of the ice storage box 151;

Control the refrigeration system to cool the ice-making compartment 113, and monitor the temperature of the ice-making compartment 113;

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 .

Compared with the refrigerator 100 control method in the first embodiment, the main difference between this embodiment and the refrigerator 100 control method in this embodiment is that the corresponding pre-cooling temperature is directly matched according to the current ice volume information of the ice storage box 151, even if the ice storage The box 151 is currently full of ice, and the defrosting unit corresponding to the ice-making evaporator 131 is turned on after pre-cooling the ice-making compartment 113 .

After matching the corresponding pre-cooling temperature according to the ice volume information, it can be determined whether to defrost the ice-making evaporator 131 according to whether the temperature of the ice-making compartment 113 reaches the pre-cooling temperature. In this way, the impact of the defrosting of the ice-making evaporator 131 on the ice-making compartment 113 can be further reduced, and abnormal or special situations can be avoided.

If the user opens the refrigerating door 121 for a long time or forgets to close the refrigerating door 121 before defrosting starts, or the user opens the small ice-making door on the ice-making compartment 113 for a long time, the temperature inside the ice-making compartment 113 will be too high. At this time, the amount of ice in the ice storage box 151 may be large, but if the ice-making compartment 113 is not pre-cooled and the defrosting unit is directly turned on to defrost the ice-making evaporator 131, the ice-making compartment will The temperature at 113 continued to rise. Therefore, in this embodiment, regardless of the amount of ice in the ice storage box 151, the corresponding pre-cooling temperature is first obtained according to the amount of ice. When the temperature of the ice-making compartment 113 reaches the pre-cooling temperature, the ice-making evaporator 131 Perform defrosting.

In this embodiment, the precooling temperature is positively correlated with the current ice volume of the ice storage box 151 , the more the current ice volume of the ice storage box 151 , the higher the corresponding precooling temperature of the ice making compartment 113 .

Further, referring to Fig. 6, "matching the corresponding pre-cooling temperature according to the ice volume information" in the control method of the refrigerator 100 includes:

If the current amount of ice in the ice storage box 151 is greater than or equal to the preset value, the pre-cooling temperature is the first pre-cooling temperature;

Otherwise, the pre-cooling temperature is a second pre-cooling temperature, wherein the first pre-cooling temperature is greater than the second pre-cooling temperature.

As a specific example, if the ice storage box 151 is full of ice volume Q, then the preset value can be 0.5Q, when the current ice volume of the ice storage box 151 is greater than or equal to 0.5Q, it can match the first pre-cooling temperature T1, And obtain the current temperature of the ice-making compartment 113, if the current temperature of the ice-making compartment 113 is greater than T1, then turn on the refrigeration system to pre-cool the ice-making compartment 113 until the temperature of the ice-making compartment 113 drops to T1, The defrosting unit corresponding to the ice-making evaporator 131 can be turned on to defrost the ice-making evaporator 131 . And when the current ice volume of the ice storage box 151 is less than 0.5Q, it can match the second pre-cooling temperature T2, because the ice volume in the ice storage box 151 is less, the second pre-cooling temperature T2 can be lower than the first pre-cooling temperature T1, If the temperature of the ice-making compartment 113 is greater than T2 at this time, the ice-making system can be turned on to pre-cool the ice-making compartment 113 until the temperature of the ice-making compartment 113 drops to T2, and the ice-making evaporator 131 can be turned on correspondingly. The defrosting unit defrosts the ice-making evaporator 131.

In this way, the pre-cooling temperature of the ice-making compartment 113 is directly matched according to the ice volume information, and the ice-making evaporator 131 is defrosted when it is confirmed that the temperature of the ice-making compartment 113 reaches the pre-cooling temperature, so that the ice-making compartment 113 can be avoided Excessive temperature will have a negative impact on the ice making device 150, and at the same time, the pre-cooling operation can be reasonably controlled to avoid excessive pre-cooling and reduce energy consumption.

Referring to FIG. 7 , an embodiment of the present invention also provides a refrigerator 100 , which includes a memory 102 and a processor 101 , and the memory 102 and the processor 101 are communicatively connected through a communication bus 104 . A computer program that can run on the processor 101 is stored in the memory 102. When the processor 101 executes the computer program, the steps in the refrigerator control method in the above-mentioned embodiments are realized. The refrigerator 100 also includes a communication interface 103 connected to a communication bus 104 for communicating with other devices in the refrigerator 100 .

An embodiment of the present invention further provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps in the method for controlling the refrigerator in the above-mentioned embodiment are implemented.

Therefore, in summary, the refrigerator control method and the refrigerator 100 provided by the present invention, when the ice-making evaporator 131 satisfies the defrosting conditions, first obtain the ice volume information in the ice storage box 151, and control the ice production process according to the ice volume information. For the pre-cooling of the compartment 113, when the amount of ice is large, you can choose not to pre-cool the ice-making compartment 113, or set a high pre-cooling temperature for the ice-making compartment 113. When the amount of ice is small, you can use a low pre-cooling temperature. 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.
