Referring to fig. 3, a method for controlling a refrigerator 100 according to a first embodiment of the present invention is shown. The refrigerator 100 control method includes:

collecting working parameters of an ice making system;

when the working parameters meet the preset normal defrosting condition of the ice making evaporator 131 and the ice amount information of the ice storage box 151 is non-full ice information, acquiring the current working state of the ice making device 150, and if the current working state meets the defrosting condition, controlling a defrosting unit corresponding to the ice making evaporator 131 to be opened;

when the ice amount information of the ice storage box 151 is detected to be full ice information, if the working parameters meet a preset ice-full defrosting condition of the ice making evaporator 131, controlling a defrosting unit corresponding to the ice making evaporator 131 to be opened.

In the present embodiment, the ice making system may include an ice making device 150 and a refrigeration system corresponding to the ice making compartment 113, such as a compressor, an ice making evaporator 131, and an ice making fan. When the ice-making evaporator 131 is excessively frozen, a defrosting unit corresponding to the ice-making evaporator 131 needs to be activated to defrost the ice-making evaporator 131 in order not to affect the operation of the ice-making evaporator 131.

When the operating parameters of the ice making system satisfy the preset normal defrosting condition, it may be determined that the ice making evaporator 131 needs defrosting, and at this time, the current operating state of the ice making device 150 may be further acquired, and it may be determined whether the current operating state of the ice making device 150 satisfies the defrosting condition. Among them, the operating state of the ice making device 150 may include an ice-turned state and a non-ice-turned state. The working state of the ice making device 150 satisfying the defrosting condition may be that the current working state of the ice making device 150 is a non-ice-turning state, that is, when the working parameter of the ice making system satisfies a preset normal defrosting condition, if the working state of the ice making device 150 is the non-ice-turning state, the defrosting unit corresponding to the ice making evaporator 131 may be controlled to be turned on to defrost the ice making evaporator 131.

In the present embodiment, the non-ice-turning state may include an ice storage state and an ice making state. The refrigerator 100 may be provided with a control panel or control buttons, and a user may control a switch of the ice making mode. When the ice making mode is turned on, the ice making device 150 may operate to make ice, and when the ice making mode is turned off, the ice making device 150 may stop making ice, for example, liquid water is not filled into the ice making tray, but if ice is still stored in the ice storage box 151, the ice making evaporator 131 continues to operate to supply cold air to the ice making compartment 113, and at this time, the operating state of the ice making device 150 may be defined as an ice storage state.

In the state where the ice making mode is opened, the operating state of the ice making device 150 may include an ice-turned state and an ice-making state. The ice-turning state may be a state in which the liquid water in the ice-making tray is frozen and then the ice in the ice-making tray is discharged into the ice bank 151. The ice-making tray may be provided with an ice-making temperature sensor, the ice-making device 150 may also be provided with a preset ice-making period, and when the ice-making temperature sensor detects that the temperature of the ice-making tray reaches a preset temperature and/or the operation duration of the ice-making device 150 reaches the ice-making period since the last ice-turning is finished, the ice-turning signal may be sent to control the ice-making device 150 to turn ice. After the ice-turning state is completed, the ice-making device 150 enters the ice-making state.

The ice-making tray can be provided with an ice-turning heating wire, and after receiving an ice-turning signal, the ice-turning heating wire can be started to heat the ice-making tray, so that ice blocks in the ice-making tray are separated from the ice-making tray. Therefore, when the current operating state of the ice making device 150 is an ice turning state, the temperature of the ice making compartment 113, especially the temperature of the ice making tray, is relatively high, if the ice making evaporator 131 is defrosted at this time, the temperature is further increased during the defrosting process, which may cause the temperature of the ice making compartment 113 to be too high, ice in the ice making tray and the ice storage box 151 may be melted to generate more water, and after defrosting is finished, the melted water is secondarily frozen when the temperature of the ice making compartment 113 is reduced, which may cause ice cubes in the ice storage box 151 to be adhered to form ice lumps. And even if the ice is turned over without heating, the ice not dropped off in the ice-making tray is easily melted by the temperature rise due to defrosting of the ice-making evaporator 131. Therefore, when the current operating state of the ice-making device 150 is the non-ice-turning state, the ice-making evaporator 131 is defrosted, and the risk of ice lumps forming in the ice bank 151 can be reduced.

When the ice amount information in the ice storage box 151 is detected to be full ice information, at this time, the ice cubes in the ice storage box 151 can emit more cold energy due to the more ice amount in the ice storage box 151, the temperature rise generated in the defrosting process of the ice making evaporator 131 does not cause the over-high temperature of the ice making compartment 113, and the influence on the ice cubes in the ice storage box 151 is small, and meanwhile, when the ice storage box 151 is in a full ice state, the ice making device 150 does not perform an ice turning operation, so that the ice making device 150 does not immediately start the next ice making cycle, and the defrosting process of the ice making evaporator 131 does not affect the ice making cycle when the ice storage box is full, and therefore, the defrosting time is optimized at this time. If the operating parameters of the ice-making system do not satisfy the preset normal defrosting conditions of the ice-making evaporator 131, it may be determined whether the operating parameters of the ice-making system satisfy the full-ice defrosting conditions of the ice-making evaporator 131, and if the full-ice defrosting conditions are satisfied, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be turned on, and the ice-making evaporator 131 is defrosted in the full-ice state, so as to minimize negative effects caused by defrosting of the ice-making evaporator 131, and at the same time, save energy consumption.

In the present embodiment, after receiving the defrosting end signal of the ice making evaporator 131, the flow of the refrigerant of the refrigeration system to the ice making evaporator 131 may be controlled, and when the temperature of the compartment of the ice making evaporator 131 is reduced to a preset temperature, the ice making fan is turned on to supply cold air to the ice making compartment 113. Therefore, the ice making fan is started after the temperature of the chamber of the ice making evaporator 131 is reduced, so that cold air can be supplied to the inside of the ice making chamber 113, and the problem that the ice making process is influenced and the energy consumption is increased due to the fact that the temperature of the chamber is increased because air with high temperature in the ice making chamber 113 is supplied to the ice making chamber 113 after the defrosting of the ice making evaporator 131 is finished is avoided.

Further, the method for controlling the refrigerator 100 according to the present embodiment further includes:

when the operating parameters satisfy the preset normal defrosting condition of the ice making evaporator 131 and the current ice amount information of the ice bank 151 is the non-full ice information, if the current operating state of the ice making device 150 is the ice turning state, the operating state of the ice making device 150 continues to be monitored.

In this embodiment, when it is detected that the current operating parameters of the ice making system satisfy the normal defrosting condition of the ice making evaporator 131, if the operating state of the ice making device 150 is an ice-turning state, the defrosting unit corresponding to the ice making evaporator 131 is not activated, so as to avoid the over-high temperature of the ice making chamber 113. At this time, the operating state of the ice making device 150 may be continuously monitored, and the operating parameters of the ice making system may be continuously monitored, and when it is detected that the operating parameters of the ice making system satisfy the defrosting condition of the ice making evaporator 131 and the operating state of the ice making device 150 is the non-ice-turning state, the defrosting unit corresponding to the ice making evaporator 131 is controlled to be turned on. Alternatively, only the operating state of the ice making device 150 may be monitored, for example, when the ice-turning state of the ice making device 150 is detected to be over, or the operating state of the ice making device 150 is detected to be changed from the ice-turning state to the ice-making state, or an ice-turning over end signal is received, the defrosting unit corresponding to the ice-making evaporator 131 may be controlled to be turned on.

Therefore, the influence of defrosting of the ice making evaporator 131 on the ice making compartment 113 and the ice blocks in the ice storage box 151 can be reduced, and the formation of ice lumps in the ice storage box 151 is avoided.

Further, in the present embodiment, the method for controlling the refrigerator 100 further includes:

if the operating parameters satisfy the normal defrosting condition of the ice making evaporator 131 and the current operating state of the ice making device 150 is the ice turning state, an opening signal is sent to a defrosting unit corresponding to the ice making evaporator 131 after the ice turning is finished, and the ice making operation of the ice making device 150 is started after a defrosting end signal is received.

The ice making operation of the ice making device 150 may include monitoring whether the current ice making time period of the ice making device 150 reaches a preset ice making period and controlling ice turning, for example, when the current ice making time period reaches the preset ice making period, the ice making device 150 may be controlled to turn ice. If the ice making evaporator 131 meets the normal defrosting condition and the ice making device 150 is in the ice turning state, the ice making evaporator 131 can be defrosted after the ice turning is finished, and the water supply device starts to supply water into the ice making tray after the ice turning is finished, but the temperature of the ice making chamber 113 is higher, and if the ice making operation is started immediately to calculate the ice making period, the liquid water in the ice making tray may not be completely frozen at the end of the ice making period, so the ice making operation can be started again after the defrosting is finished.

if the operating parameters satisfy the preset normal defrosting conditions of the ice making evaporator 131 and the current operating state of the ice making device 150 is the ice making state, a start signal is sent to a defrosting unit corresponding to the ice making evaporator 131 and the ice making device 150 is controlled to stop the ice making operation.

When the ice making device 150 is in the ice making state, the ice making evaporator 131 is defrosted, and since the water in the ice making tray is in an incompletely frozen state and is greatly influenced by the temperature of the ice making compartment 113, the temperature of the ice making compartment 113 is increased due to defrosting of the ice making evaporator 131, which may melt partially frozen ice cubes in the ice making tray. Therefore, when the defrosting unit corresponding to the ice making evaporator 131 is controlled to start the defrosting operation, the ice making operation is stopped, the parameters such as the ice making time length of the ice making device 150 in the current ice making period are not monitored continuously, and the situation that the ice blocks are not completely frozen when the ice making period is reached due to the fact that invalid ice making time in the defrosting process of the ice making evaporator 131 is calculated is avoided.

if the operating parameter satisfies the normal defrosting condition of the ice making evaporator 131 and the current operating state of the ice making device 150 is the ice making state, the ice making operation is restarted after receiving a defrosting end signal of the ice making evaporator 131.

In the present embodiment, after stopping the ice making operation when defrosting the ice making evaporator 131 in the ice making state, the ice making parameters in the current ice making cycle that have been stored, such as the ice making time length that has been recorded, the temperature sensed by the temperature sensor, and the like, may be cleared, and after defrosting the ice making evaporator 131 is finished, the ice making operation may be restarted, such as recalculating the ice making cycle.

Therefore, the ice making device 150 can be ensured to continue to operate normally after the ice making evaporator 131 is defrosted, and the condition that the temperature of the compartment is increased due to the defrosting of the ice making evaporator 131, so that the error of the ice making system is avoided.

Further, in the present embodiment, the operating parameters of the ice making system may include an accumulated operating time period of the compressor after the last defrosting of the ice making evaporator 131 is finished and/or the number of ice making times of the ice making device 150 after the last defrosting of the ice making evaporator 131 is finished.

The "the operation parameter satisfies the normal defrosting condition of the ice-making evaporator 131" may include: the accumulated operation time of the compressor after the last defrosting of the ice making evaporator 131 is longer than or equal to the preset normal defrosting period of the ice making evaporator 131, or the ice making times of the ice making device 150 are longer than or equal to the preset normal defrosting and ice making times of the ice making evaporator 131.

The "the operation parameter satisfies the ice-full defrosting condition of the ice-making evaporator 131 preset" may include: the accumulated operation time of the compressor after the last defrosting of the ice making evaporator 131 is longer than or equal to the preset full-icing defrosting period of the ice making evaporator 131, or the ice making times of the ice making device 150 are longer than or equal to the preset full-icing defrosting ice making times.

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

Of course, the phrase "the operation parameter satisfies the normal defrosting condition of the ice making evaporator 131" may also mean that the accumulated operation time of the compressor after the last defrosting of the ice making evaporator 131 is finished is greater than or equal to the preset normal defrosting period of the ice making evaporator 131, and the ice making frequency of the ice making device 150 is greater than or equal to the preset normal defrosting and ice making frequency of the ice making evaporator 131. The "the operating parameter satisfies a preset full-icing defrosting condition" may include: the accumulated operation time of the compressor after the last defrosting of the ice making evaporator 131 is longer than or equal to the preset full-icing defrosting period of the ice making evaporator 131, and the ice making times of the ice making device 150 are longer than or equal to the preset full-icing defrosting ice making times.

Specifically, for example, if the defrosting normality cycle of the ice making evaporator 131 is 20 hours, the defrosting full cycle may be 15 hours, and when it is detected that the accumulated operation time of the compressor reaches 20 hours after the ice making evaporator 131 defrosts last time, it may be determined that the ice making evaporator 131 satisfies the defrosting normality condition regardless of the amount of ice in the ice bank 151, and if the ice amount information of the ice bank 151 is not full ice information, it may be determined that the ice making device 150 is in the non-ice-turning state, the defrosting unit corresponding to the ice making evaporator 131 may be controlled to be turned on, and if the ice amount information of the ice bank 151 is full ice information, the ice making device 150 may not perform an ice-turning operation, and thus, it may be determined that the ice making device 150 is in the non-ice-turning state, and the defrosting unit corresponding to the ice making evaporator 131 may be controlled to be turned on.

When the ice bank 151 is full of ice, if the operating parameters of the ice making system do not satisfy the normal defrosting condition of the ice making evaporator 131, it may be determined whether the accumulated operating time of the compressor is greater than or equal to 15 hours after the ice making evaporator 131 finishes defrosting last time, and if so, it may be determined that the ice making evaporator 131 satisfies the full-ice defrosting condition, and the defrosting unit corresponding to the ice making evaporator 131 may be controlled to be opened in advance to defrost the ice making evaporator 131.

If the preset normal defrosting and ice making times of the ice making evaporator 131 is 20 times, the preset full-icing defrosting and ice making times can be 15 times, when the ice making device 150 makes ice for 20 times after the last defrosting is detected, whether the ice storage box is in a full-ice state or a non-full-ice state can be judged that the ice making evaporator 131 meets the normal defrosting condition, and if the ice storage box is in a non-full-ice state and the working state of the ice making device 150 is in a non-ice turning state at this time, a defrosting signal of the ice making evaporator 131 can be sent out, a defrosting unit corresponding to the ice making evaporator 131 is controlled to be opened, and the ice making evaporator 131 is defrosted; if the ice storage box is in the full ice state, the ice-making device 150 does not perform the ice-turning operation when the ice storage box is full ice, and thus the current working state of the ice-making device 150 can be determined as the non-ice-turning state, and the defrosting unit corresponding to the ice-making evaporator 131 can be directly controlled to be opened. When the received ice amount information of the ice storage box 151 is full ice information, it may be determined whether the ice making times of the ice making device 150 after the last defrosting of the ice making evaporator 131 is over or equal to 15 times, and if so, it may be determined that the ice making evaporator 131 has satisfied a full ice defrosting condition, and a defrosting signal may be sent to the ice making evaporator 131 to control a defrosting unit corresponding to the ice making evaporator 131 to be turned on in advance to turn on the ice making evaporator 131 to defrost.

Thus, when the ice amount in the ice bank 151 is full, the ice making evaporator 131 can be defrosted in advance, so that the negative influence caused by defrosting of the ice making evaporator 131 is minimized, the temperature rise of the ice making compartment 113 caused by defrosting of the ice making evaporator 131 is reduced, the energy consumption is reduced, and the risk of melting ice cubes in the ice bank 151 can be reduced.

As shown in fig. 6, a method for controlling a refrigerator 100 according to a second embodiment of the present invention is shown. The refrigerator 100 control method includes:

collecting working parameters of an ice making system;

when the working parameters meet the normal defrosting condition of the ice making evaporator 131, acquiring the current working state of the ice making device 150, and if the current working state meets the defrosting condition, judging whether the ice making compartment 113 needs to be precooled according to the ice amount information of the ice storage box 151;

if the ice making compartment 113 needs to be precooled, the refrigeration system is controlled to refrigerate the ice making compartment 113, the temperature of the ice making compartment 113 is monitored, and when the temperature of the ice making compartment 113 is equal to or lower than the precooling temperature, the defrosting unit corresponding to the ice making evaporator 131 is controlled to be started;

if the ice-making compartment 113 does not need to be pre-cooled, the defrosting unit corresponding to the ice-making evaporator 131 is controlled to be started;

when it is detected that the ice amount information of the ice bank 151 is full ice information, if the operating parameter meets a preset full ice and defrosting condition of the ice making evaporator 131, controlling a defrosting unit corresponding to the ice making evaporator 131 to be opened.

The refrigerator control method provided by the embodiment is a further improvement of the refrigerator control method provided by the first embodiment. The difference between the control method of the refrigerator 100 provided in this embodiment and the control method of the refrigerator 100 in the first embodiment is that when the operating parameter meets a preset normal defrosting condition, if the current operating state of the ice making device 150 meets the defrosting condition, it is determined whether the ice making compartment 113 needs to be precooled according to the ice amount information of the ice storage box 151. When the amount of ice in the ice bank 151 is greater than a certain value, the ice blocks can release more cold, and the influence of defrosting of the ice making evaporator 131 on the temperature of the ice making compartment 113 is small, so that the ice making compartment 113 is not precooled, and the defrosting unit is directly controlled to be turned on to defrost the ice making evaporator 131, so that the energy consumption can be further saved, and the over-precooling can be prevented. When precooling is needed, the temperature of the ice making chamber is reduced to the precooling temperature and then defrosting is carried out, so that the problem that the ice making process is influenced due to the fact that the temperature of the ice making chamber is too high after an ice making evaporator defrosts and ice cubes in an ice storage box are melted can be avoided.

The pre-cooling temperature may be a fixed temperature, or may be changed according to the operating condition of the ice making device 150 or a parameter affecting the temperature of the ice making compartment, and may be stored in the memory of the refrigerator 100 in advance.

For example, when the operating parameters of the ice making system satisfy the normal defrosting condition of the ice making evaporator 131, if the operating state of the ice making device 150 satisfies the defrosting condition and the ice making compartment needs to be pre-cooled, the pre-cooling temperature corresponding to the ice making compartment 113 may be obtained first, and the temperature of the ice making compartment 113 may be monitored, for example, the temperature sensor in the ice making compartment 113 may be controlled to detect the temperature of the ice making compartment 113, and of course, the temperature sensor in the ice making compartment 113 may detect the temperature in the ice making compartment 113 at regular time and upload and store the detected temperature into the memory of the refrigerator 100, and when the operating parameters of the ice making system satisfy the defrosting condition of the ice making evaporator 131, the stored temperature of the ice making compartment 113 may be directly called.

And if the pre-cooling temperature is-8 ℃ and the current temperature of the ice-making chamber 113 is-3 ℃, controlling the cold system to refrigerate the ice-making chamber 113, and when the temperature of the ice-making chamber 113 is reduced to the pre-cooling temperature of-8 ℃, controlling to start a defrosting unit corresponding to the ice-making evaporator 131 to defrost the ice-making evaporator 131. Of course, if the temperature of the current ice making compartment 113 is lower than-8 ℃, for example, minus 9 ℃, the ice making compartment 113 does not need to be refrigerated, and the defrosting unit corresponding to the ice making evaporator 131 can be directly started.

In this way, when the temperature of the ice making compartment 113 is-8 ℃, the ice making evaporator 131 is defrosted, and if the temperature of the ice making compartment 113 is increased by 5 ℃ in the defrosting process, the temperature of the ice making compartment 113 is still-3 ℃ after the defrosting of the ice making evaporator 131 is finished.

In this way, even if the temperature of the ice making compartment 113 is increased during defrosting of the ice making evaporator 131, the temperature of the ice making compartment 113 is not excessively high, and the ice making process after the ice cubes stored in the ice bank 151 and defrosting are finished is not affected.

Referring to fig. 7, in an embodiment, the determining whether the ice-making compartment 113 needs to be precooled according to the ice amount information of the ice bank 151 may include:

if the ice amount of the ice bank 151 is greater than or equal to the first preset value, the ice making compartment 113 does not need to be pre-cooled;

if the ice amount of the ice bank 151 is less than the first preset value, the ice-making compartment 113 needs to be pre-cooled.

Referring to fig. 4, in another embodiment, "determining whether pre-cooling of the ice-making compartment 113 is required according to the ice amount information of the ice bank 151" may include:

if the ice amount information of the ice storage box is not full ice information, precooling the ice making chamber is needed;

if the ice amount information of the ice storage box is full ice information, the ice making chamber does not need to be precooled.

Thus, since the amount of ice in the ice bank 151 is large, defrosting of the ice making evaporator 131 does not cause excessive temperature rise of the ice making compartment 113, and when the amount of ice in the ice bank is full of ice or greater than a certain value, defrosting of the ice making evaporator can be performed directly without precooling, so as to save energy consumption.

Further, as shown in fig. 5, in the present embodiment, the method for controlling the refrigerator 100 further includes:

and if the ice making chamber 113 needs to be precooled, matching the corresponding precooling temperature according to the ice amount information.

The precooling temperature may be positively correlated with the ice amount of the ice storage box 151, and the more the ice amount in the ice storage box 151 is, the more the cold energy released by the ice cubes is, and the smaller the temperature rise of the ice making compartment 113 in the defrosting process of the ice making evaporator 131 is, so that the matched precooling temperature may be higher.

Specifically, for example, if the full ice amount in the ice bank 151 is Q, if the current temperature of the ice making compartment 113 is-3 ℃, and if the current ice amount of the ice bank 151 is Q, the temperature of the ice making compartment 113 may rise by 2 ℃ during defrosting of the ice making evaporator 131, and after defrosting is finished, the temperature of the ice making compartment 113 is-1 ℃, and the ice cubes in the ice bank 151 are not melted, so that the ice making compartment 113 does not need to be pre-cooled before defrosting. If the current ice amount of the ice storage box 151 is 0.8Q, the temperature of the ice making chamber 113 may rise by 4 ℃ in the defrosting process of the ice making evaporator 131, at this time, the ice making chamber 113 needs to be pre-cooled before defrosting, the pre-cooling temperature may be-5 ℃, and when the ice amount of the ice storage box 151 is 0.6Q, defrosting of the ice making evaporator 131 may cause the temperature of the ice making chamber 113 to rise by 6 ℃, so that the corresponding pre-cooling temperature may be-7 ℃ at this time, so that the temperature of the ice making chamber 113 is below 0 ℃ after defrosting of the ice making evaporator 131 is finished, and ice blocks in the ice storage box 151 cannot be melted.

In this embodiment, "matching the corresponding pre-cooling temperature according to the ice amount information" may include:

if the current ice amount is greater than or equal to a second preset value, the precooling temperature is a first precooling temperature;

otherwise, the precooling temperature is a second precooling temperature;

and the second preset value is smaller than the first preset value, and the second precooling temperature is smaller than the first precooling temperature.

For example, if the full ice amount of the ice storage box 151 is Q, the first preset value may be 0.8Q, the second preset value may be 0.5Q, and when the current ice amount in the ice storage box 151 is greater than or equal to the first preset value of 0.8Q, the ice making compartment 113 does not need to be precooled, and the defrosting unit corresponding to the ice making evaporator 131 may be directly opened to defrost the ice making evaporator 131; when the current ice amount of the ice storage box 151 is less than a first preset value of 0.8Q and is greater than or equal to a second preset value of 0.5Q, the pre-cooling temperature corresponding to the ice making compartment 113 may be T1, at this time, if the temperature of the ice making compartment 113 is greater than T1, the refrigeration system may be started to pre-cool the ice making compartment 113, when the temperature of the ice making compartment 113 is reduced to T1, the defrosting unit corresponding to the ice making evaporator 131 is controlled to be started to defrost the ice making evaporator 131, if the current ice amount of the ice storage box 151 is less than the second preset value of 0.5Q, the pre-cooling temperature corresponding to the ice making compartment 113 may be T2, and T2 is less than T1 to ensure that ice blocks in the ice storage box 151 in the ice making compartment 113 are not affected, at this time, if the temperature of the ice making compartment 113 is greater than T2, the refrigeration system may be started to pre-cool the ice making compartment 113, and, when the temperature of the ice making compartment 113 is reduced to T2, the defrosting unit corresponding to defrost the ice making evaporator 131 is controlled to be started.

Therefore, the precooling temperature of the ice making chamber 113 is directly matched according to the ice amount information, and the ice making evaporator 131 is defrosted when the temperature of the ice making chamber 113 is confirmed to reach the precooling temperature, so that the ice making device 150 can be prevented from being negatively influenced by overhigh temperature of the ice making chamber 113, meanwhile, the precooling operation can be reasonably controlled, excessive precooling is avoided, and the energy consumption is reduced.

Referring to fig. 8, a method for controlling a refrigerator 100 according to a third embodiment of the present invention is provided. The control method of the refrigerator 100 includes:

collecting working parameters of an ice making system;

when the working parameters meet the preset normal defrosting condition of the ice making evaporator 131, acquiring the current working state of the ice making device 150, and if the current working state meets the defrosting condition, controlling the refrigerating system to refrigerate the ice making chamber 113;

when the temperature of the ice making compartment 113 is monitored to be equal to or lower than the pre-cooling temperature, controlling a defrosting unit corresponding to the ice making evaporator 131 to be started;

when the ice amount information of the ice storage box 151 is full ice information and the working parameters meet the preset full ice defrosting condition of the ice making evaporator 131, controlling the refrigerating system to refrigerate the ice making compartment 113;

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.

The refrigerator control method of the present embodiment is a further improvement of the refrigerator control method of the second embodiment of the present invention. The method for controlling the refrigerator 100 of the present embodiment is different from the method for controlling the refrigerator 100 of the second embodiment in that, when the ice amount information of the ice bank 151 is full ice information, the defrosting unit corresponding to the ice making evaporator 131 is not directly turned on to defrost the ice making evaporator 131, but the defrosting unit is turned on to defrost the ice making evaporator 131 after the ice making compartment 113 is precooled.

In this way, it is possible to further prevent the temperature of the ice-making compartment 113 from being excessively high in a full ice state due to an abnormal condition. If the user opens the refrigeration door 121 or the ice making small door for a long time in the full ice state, which causes the temperature of the ice making chamber 113 to be too high, at this time, if it is detected that the ice making evaporator 131 meets the full ice defrosting condition, the corresponding defrosting unit is directly opened to defrost the ice making evaporator 131, which may cause the temperature in the ice making chamber 113 to be further increased, and the ice cubes in the ice storage box 151 to be melted. Therefore, the defrosting unit corresponding to the ice-making evaporator 131 can be controlled to be turned on after the ice-making compartment 113 is precooled even when the ice is full.

The pre-cooling temperature may be a preset fixed temperature, or may be a temperature that varies according to the condition of the ice making device or other parameters that may affect the temperature of the ice making compartment.

Further, referring to fig. 9, in the present embodiment, the method for controlling the refrigerator 100 further includes:

the corresponding pre-cooling temperature is matched according to the ice amount information of the ice bank 151.

Wherein, the pre-cooling temperature may be positively correlated with the current ice amount of the ice bank 151, and the more the current ice amount of the ice bank 151 is, the higher the corresponding pre-cooling temperature may be.

Specifically, if the ice amount of the ice bank 151 is Q, when the ice amount of the ice bank 151 is full ice, the pre-cooling temperature is T1, and when the ice amount of the ice bank 151 is not full ice, if the pre-cooling temperature is greater than or equal to a preset value, for example, greater than or equal to 0.5Q, the corresponding pre-cooling temperature is T2, and when the ice amount of the ice bank 151 is less than the preset value, for example, less than 0.5Q, the corresponding pre-cooling temperature is T3, where T1 is greater than T2, and T2 is greater than T3.

If the temperature of the ice making compartment 113 is less than or equal to the corresponding pre-cooling temperature, the defrosting unit corresponding to the ice making evaporator 131 may be directly turned on, and if the temperature of the ice making compartment 113 is greater than the corresponding pre-cooling temperature, the refrigeration system is turned on to refrigerate the ice making compartment 113 until the temperature of the ice making compartment 113 reaches the corresponding pre-cooling temperature, and then the defrosting unit corresponding to the ice making evaporator 131 is controlled to be turned on.

Thus, the pre-cooling temperature can be controlled according to the ice amount of the ice bank 151, so that pre-cooling failure or over-pre-cooling can be prevented, the temperature in the ice bank 151 can be prevented from being too low, and energy consumption can be reduced.

Referring to fig. 10, an embodiment of the present invention further provides a refrigerator 100, which includes a memory 102 and a processor 101, wherein the memory 102 and the processor 101 are communicatively connected through a communication bus 104. The memory 102 stores a computer program operable on the processor 101, and the processor 101 implements the steps of the refrigerator control method in the above embodiment when executing the computer program. The refrigerator 100 also includes a communication interface 103 connected to a communication bus 104 for communicating with other devices within the refrigerator 100.

An embodiment of the present invention further provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the computer program implements the steps in the refrigerator control method in the above embodiment.

In summary, according to the refrigerator control method provided by the present invention, when it is detected that the ice amount information of the ice storage box is full ice information, if the ice making evaporator does not satisfy the normal defrosting condition at this time, it can be determined whether the ice making evaporator satisfies the full ice defrosting condition, and if the ice making evaporator satisfies the full ice defrosting condition at this time, the defrosting unit can be controlled to start to defrost the ice making evaporator in advance, so as to save energy consumption and reduce negative effects of defrosting of the ice making evaporator on the ice making device.
