Referring to fig. 3, a method for controlling a refrigerator 100 according to a first embodiment of the present invention includes:
when the defrosting condition of the ice making evaporator 131 is met, judging whether to precool the ice making compartment 113 according to the current 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, and when the temperature of the ice making compartment 113 is monitored to reach the corresponding precooling temperature, a starting signal is sent to a defrosting unit corresponding to the ice making evaporator 131;
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.
In the present embodiment, satisfying the defrosting condition for ice-making evaporator 131 may include satisfying a normal defrosting condition or an abnormal defrosting condition for ice-making evaporator 131. Among them, satisfying the normal defrosting condition of the ice-making evaporator 131 may include: after the last defrosting of the ice making evaporator 131 is finished, the accumulated running time length of the compressor reaches the preset defrosting period of the ice making evaporator 131, or the ice making times of the ice making device 150 reach the preset defrosting and ice making times of the ice making evaporator 131. The condition that the ice making evaporator 131 meets the abnormal defrosting condition may include that the temperature of the ice making evaporator compartment 130 is less than a preset value, or that the current of the ice making fan is greater than the preset value and the rotating speed is less than the preset value, at this time, it may be determined that the ice making evaporator 131 or the ice making fan is blocked by ice, and defrosting of the ice making evaporator 131 is required.
In the embodiment, since the temperature of the ice making compartment 113 rises during defrosting of the ice making evaporator 131, negative effects may be caused on the ice making device 150, for example, when the temperature of the ice making compartment 113 is higher than zero, ice cubes in the ice storage box 151 may be melted, and after defrosting is finished, liquid water obtained by melting ice cubes in the ice storage box 151 freezes, so that the ice cubes in the ice storage box 151 are adhered to form ice lumps. Therefore, in order to reduce the influence of defrosting of the ice making evaporator 131 on the temperature of the ice making compartment 113, the refrigeration system may be controlled to pre-cool the ice making compartment 113 before defrosting of the ice making evaporator 131, so as to reduce the temperature of the ice making compartment 113, and when the temperature in the ice making compartment 113 reaches the pre-cooling temperature, the ice making evaporator 131 is defrosted again, so that the temperature of the ice making compartment 113 after the temperature is raised in the defrosting process of the ice making evaporator 131 is not too high.
The pre-cooling temperature may be a predetermined fixed temperature or may be a temperature that varies according to other parameters that affect the temperature of the ice-making compartment.
Specifically, for example, if the pre-cooling temperature is-10 ℃, the refrigeration system may be controlled to rapidly supply cold to the ice making compartment 113 before defrosting the ice making evaporator 131, and the temperature of the ice making compartment 113 is reduced to-10 ℃, so that even if the temperature is increased during defrosting of the ice making evaporator 131, if the temperature of the ice making compartment is increased by 5 ℃ due to defrosting of the ice making evaporator, the temperature of the ice making compartment is still-5 ℃ after defrosting is finished, and the ice blocks in the ice storage box 151 are not affected.
Because the more the ice amount in the ice storage box 151 is, the more the cold amount which can be emitted by the ice cubes is, the less the temperature rise of the ice making chamber 113 is caused in the defrosting process of the ice making evaporator 131, and when the ice amount in the ice storage box 151 is larger than a certain amount, the temperature generated in the defrosting process of the ice making evaporator 131 may not cause the temperature of the ice making chamber 113 to be too high, therefore, whether the ice making chamber 113 needs to be pre-cooled or not can be judged according to the ice amount information in the ice storage box 151, so the pre-cooling time can be reduced, the noise generated by a compressor in the pre-cooling process can be avoided, meanwhile, the defrosting efficiency can be improved, and the energy consumption can be saved.
Referring to fig. 4, in the present embodiment, the method of controlling the refrigerator 100, in which "determining whether to pre-cool the ice-making compartment 113 according to the current ice amount information of the ice bank 151" includes:
judging whether the current ice amount of the ice bank 151 is less than a first preset value;
if yes, precooling the ice making chamber 113;
if not, ice making compartment 113 does not need to be precooled.
In the present embodiment, the first preset value may be a full ice amount Q of the ice bank 151, or may be any other suitable ice amount, and the first preset value may be greater than 0.5Q. When the ice amount of the ice bank 151 is greater than the first preset value, the ice amount in the ice bank 151 is large, and at this time, the temperature rise generated in the defrosting process of the ice making evaporator 131 does not cause the temperature of the ice making compartment 113 to rise too much, and the ice blocks in the ice bank 151 are not melted, so that precooling of the ice making compartment 113 is not needed, and the defrosting unit corresponding to the ice making evaporator 131 is directly opened to defrost the ice making evaporator 131, so that the energy consumption can be saved.
Further, in this embodiment, the refrigerator control method further includes:
and if the ice making chamber needs to be precooled, matching the corresponding precooling temperature according to the ice amount information.
The temperature rise of the ice making chamber in the defrosting process of the ice making evaporator is related to the ice amount of the ice storage box, the more the ice amount of the ice storage box is, the more the cold energy which can be emitted by ice blocks is, and the smaller the temperature rise of the ice making chamber is, so that the corresponding precooling temperature can be matched according to the ice amount information of the ice storage box, the energy consumption is saved, and the situation that precooling is not in place or is excessive is avoided.
Further, in the present embodiment, the pre-cooling temperature is positively correlated to the current ice amount.
"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.
In this embodiment, the larger the current ice amount of the ice bank 151 is, the smaller the temperature rise of the ice making compartment 113 in the defrosting process of the ice making evaporator 131 is, and thus, the higher the pre-cooling temperature corresponding to the ice making compartment 113 may be.
For example, if the full ice amount of the ice bank 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 bank 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 first, and 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 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 first, and when the temperature of the ice making compartment 113 is reduced to T2, the defrosting unit corresponding to the ice making evaporator 131 is controlled to be started to defrost the ice making evaporator 131.
Therefore, whether the ice making compartment is precooled or not and matched with a proper precooling temperature can be judged according to the current ice amount in the ice storage box 151, so that the energy consumption is reduced, and the defrosting efficiency is improved.
Referring to fig. 5, in order to a method for controlling a refrigerator 100 according to a second embodiment of the present invention, the method for controlling the refrigerator 100 includes:
when the defrosting condition for the ice making evaporator 131 is satisfied, matching a corresponding pre-cooling temperature according to the ice amount information for the ice bank 151;
controlling a refrigeration system to refrigerate the ice making compartment 113 and monitoring 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 method for controlling the refrigerator 100 of the first embodiment, the method for controlling the refrigerator 100 of the present embodiment is mainly distinguished in that the corresponding precooling temperature is directly matched according to the current ice amount information of the ice bank 151, and even if the ice bank 151 is currently in a full ice state, the defrosting unit corresponding to the ice making evaporator 131 is turned on after precooling the ice making compartment 113.
After the corresponding pre-cooling temperature is matched according to the ice amount information, whether defrosting is performed on the ice making evaporator 131 can be judged according to whether the temperature of the ice making compartment 113 reaches the pre-cooling temperature. In this way, the influence of defrosting of ice making evaporator 131 on ice making compartment 113 can be further reduced, and abnormalities or special situations can be avoided.
If the user opens the refrigeration door 121 for a long time or forgets to close the refrigeration door 121 before defrosting starts, or the user opens the small ice-making door on the ice-making chamber 113 for a long time, the temperature inside the ice-making chamber 113 is too high, and the amount of ice in the ice storage box 151 may be too large, but if the ice-making chamber 113 is not pre-cooled and the defrosting unit is directly opened to defrost the ice-making evaporator 131, the temperature of the ice-making chamber 113 will continuously rise. Therefore, in the embodiment, no matter how much ice is stored in the ice storage box 151, a corresponding pre-cooling temperature is obtained according to the amount of ice, and when the temperature of the ice making compartment 113 reaches the pre-cooling temperature, the ice making evaporator 131 is defrosted.
In the present embodiment, the pre-cooling temperature is 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 pre-cooling temperature of the corresponding ice making compartment 113 is.
Further, referring to fig. 6, the step of "matching the pre-cooling temperature according to the ice amount information" in the control method of the refrigerator 100 includes:
if the current ice amount of the ice bank 151 is greater than or equal to a preset value, the pre-cooling temperature is a first pre-cooling temperature;
otherwise, the precooling temperature is a second precooling temperature, wherein the first precooling temperature is greater than the second precooling temperature.
For example, if the full ice amount of the ice bank 151 is Q, the preset value may be 0.5Q, when the current ice amount of the ice bank 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 compartment 113 is obtained, and if the current temperature of the ice making compartment 113 is greater than T1, the refrigeration system is started to precool the ice making compartment 113, until the temperature of the ice making compartment 113 is reduced to T1, and the defrosting unit corresponding to the ice making evaporator 131 is started to defrost the ice making evaporator 131. And when the current ice amount of the ice storage box 151 is less than 0.5Q, the second pre-cooling temperature T2 may be matched, because the ice amount in the ice storage box 151 is small, the second pre-cooling temperature T2 may be less than the first pre-cooling temperature T1, if the temperature of the ice making compartment 113 is greater than T2, the ice making system may be opened to pre-cool the ice making compartment 113, until the temperature of the ice making compartment 113 is reduced to T2, the defrosting unit corresponding to the ice making evaporator 131 may be opened to defrost the ice making evaporator 131.
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. 7, 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 thereon a computer program operable on the processor 101, and the processor 101 implements the steps of the refrigerator control method in the above-described 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 also provides a computer-readable storage medium having a computer program stored thereon, where the computer program, when executed by a processor, implements the steps in the refrigerator control method in the above-mentioned embodiment.
