[0031] At present, with the improvement of people's living standards, the popularity of refrigerators is also increasing. Through the operation of its own refrigeration process, the refrigerator can keep the food stored inside it fresh or refrigerate for a long time. Nowadays, with the increase in users' demand for ice making, various brands have gradually begun to launch high-end smart refrigerator products equipped with ice making functions. Among them, the relevant technology discloses a refrigerator, including a refrigerator body, a refrigeration device and a controller. The refrigerator body is provided with a refrigeration chamber and a freezer chamber. The refrigeration device and the controller are electrically connected, and both are fixed on the refrigerator body. It also includes: an ice making chamber, which is arranged in the freezer chamber; a cooling channel, which is arranged in the refrigerator body and connects the refrigeration chamber and the ice making chamber; a channel switch, which can control the conduction and closing of the cooling channel.

[0032] After the refrigerator is powered off, the related technology can use the heat absorbed by the melting of ice in the ice-making chamber to lower the temperature in the refrigerator compartment, thereby extending the time the refrigerator compartment maintains a low temperature, but it needs to ensure that there are always enough ice cubes stored in the ice-making chamber. Before the refrigerator is powered off, it takes a lot of cold energy to keep these ice cubes from melting for a long time, which is not conducive to the energy-saving operation of the refrigerator.

[0033] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling a refrigerator, comprising:

[0034] S101, the processor obtains power off information of the refrigerator.

[0035] S102, the processor controls the operation of the ice-making device according to the power-off information of the refrigerator to make ice cubes before the refrigerator is powered off.

[0036] The method for controlling a refrigerator provided by the embodiment of the present disclosure is adopted. The refrigerator is provided with an ice-making device, which can make ice cubes to maintain the low-temperature storage environment required for food after the refrigerator is powered off. By obtaining the power off information of the refrigerator and controlling the ice-making device to operate accurately accordingly, the embodiment of the present disclosure can pre-make an appropriate amount of ice cubes before the refrigerator is powered off. On the one hand, the prepared ice cubes can be used to delay the temperature rise in the refrigerator compartment after the refrigerator is powered off, which is beneficial to ensuring the preservation effect of food stored in the refrigerator. On the other hand, it can avoid consuming a lot of cold energy to maintain the ice cubes before the refrigerator is powered off, which is beneficial to the energy-saving operation of the refrigerator.

[0037] Optionally, the power off information of the refrigerator includes the power off duration and / or the power off time of the refrigerator. The power off time refers to the time point when the power supply of the refrigerator is interrupted. Correspondingly, the power off information of the refrigerator also includes the call time, and the call time refers to the time point when the power supply of the refrigerator is restored. On this basis, the power off duration of the refrigerator can be calculated according to the difference between the call time and the power off time. That is, the power off duration refers to the cumulative time from the power outage to the power restoration of the refrigerator. Therefore, the embodiment of the present disclosure can determine whether the refrigerator will have a power outage in the next period of time by obtaining the above-mentioned power off information. And when it is confirmed that the refrigerator is about to be powered off, it can reasonably predict the corresponding ice demand after the refrigerator is powered off based on the above-mentioned power off information, which is conducive to maintaining the low-temperature storage environment required for food after the refrigerator is powered off.

[0038] Optionally, the processor obtains the power outage information of the refrigerator, including: the processor obtains the historical power outage information of the refrigerator; the processor predicts the power outage information of the refrigerator based on the historical power outage information of the refrigerator. In this way, the embodiment of the present disclosure can go to the historical database to obtain and match the historical power outage information of the refrigerator based on the current time, location and / or refrigerator operation information, so that the power outage information of the refrigerator can be predicted in combination with the power outage law. Then, the ice-making device is controlled to operate accurately, so as to pre-make an appropriate amount of ice cubes before the refrigerator is powered off, which is conducive to maintaining the low-temperature storage environment required for food after the refrigerator is powered off.

[0039] Optionally, the processor obtains the power outage information of the refrigerator, including: the processor obtains the power outage announcement information; the processor determines the power outage information of the refrigerator according to the power outage announcement information. In this way, the embodiment of the present disclosure can search and match the power outage announcement information on the official website, public account or mini program based on the current time, location and / or refrigerator operation information, so that the power outage information of the refrigerator can be determined in combination with the published information. Then, the ice-making device is controlled to operate accurately, so as to pre-make an appropriate amount of ice cubes before the refrigerator loses power, which is conducive to maintaining the low-temperature storage environment required for food after the refrigerator loses power.

[0040] Optionally, the processor controls the operation of the ice-making device according to the power-off information of the refrigerator, including: the processor determines the target parameters of the ice-making device according to the power-off information of the refrigerator; the processor controls the ice-making device to operate according to the target parameters. In this way, the embodiment of the present disclosure can predict the corresponding ice demand after the refrigerator is powered off according to the power-off information of the refrigerator, and control the ice-making device to operate accurately by determining the target parameters of the ice-making device, so that an appropriate amount of ice can be made in advance before the refrigerator is powered off, which is conducive to maintaining the low-temperature storage environment required for food after the refrigerator is powered off.

[0041] Combination Figure 2 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0042] S201, the processor obtains power off information of the refrigerator.

[0043] S202: The processor determines target parameters of the ice-making device according to power-off information of the refrigerator.

[0044] S203, the processor controls the ice-making device to operate according to the target parameters to make ice cubes before the refrigerator is powered off.

[0045] The target parameters include a target ice making amount and / or a target start time.

[0046] Using the method for controlling a refrigerator provided by the embodiment of the present disclosure, the refrigerator is provided with an ice-making device, which can make ice cubes to maintain the low-temperature storage environment required for food after the refrigerator is powered off. By obtaining the power-off information of the refrigerator, the embodiment of the present disclosure can determine whether the refrigerator will be powered off within the next period of time. If so, the embodiment of the present disclosure further predicts the corresponding ice demand after the refrigerator is powered off, and determines the target ice-making amount and / or target start-up time of the ice-making device accordingly, so as to control the accurate operation of the ice-making device, so as to make an appropriate amount of ice cubes in advance before the refrigerator is powered off. On the one hand, the produced ice cubes can be used to delay the temperature rise in the refrigerator compartment after the refrigerator is powered off, which is beneficial to ensure the preservation effect of food stored in the refrigerator. On the other hand, it can avoid consuming a lot of cold energy to maintain ice cubes before the refrigerator is powered off, which is beneficial to the energy-saving operation of the refrigerator.

[0047] Optionally, the processor determines the target parameters of the ice-making device according to the power-off information of the refrigerator, including: the processor determines the target ice-making amount of the ice-making device according to the power-off duration of the refrigerator; the processor determines the target start-up time of the ice-making device according to the power-off time of the refrigerator and the target ice-making amount of the ice-making device. In this way, the embodiment of the present disclosure can analyze the heat fluctuation of the refrigerator compartment during the power-off duration, and match the target ice-making amount of the ice-making device accordingly, so that sufficient ice cubes can be made to delay the temperature rise phenomenon in the refrigerator compartment, which is conducive to ensuring the preservation effect of the food stored in the refrigerator. Then the embodiment of the present disclosure further determines the target start-up time of the ice-making device based on the target ice-making amount of the ice-making device and the power-off time of the refrigerator. By controlling the ice-making device to start making ice on time at the target start-up time, the embodiment of the present disclosure can ensure that the ice-making device can make sufficient ice cubes before the refrigerator is powered off, and can also avoid the ice-making device from making ice cubes too early and maintaining ice cubes to cause energy waste, which is conducive to energy-saving operation of the refrigerator.

[0048] Optionally, the processor determines the target ice making amount of the ice making device according to the power-off duration of the refrigerator, including: the processor obtains the natural temperature change rate of the refrigerator compartment; the processor determines the fluctuating temperature of the refrigerator compartment according to the power-off duration of the refrigerator and the natural temperature change rate of the refrigerator compartment; the processor determines the target ice making amount of the ice making device according to the fluctuating temperature of the refrigerator compartment. In this way, the embodiment of the present disclosure first obtains the natural temperature change rate of the refrigerator compartment, that is, the temperature rise value of the refrigerator compartment per unit time without refrigeration. When the refrigerator is about to be powered off, the embodiment of the present disclosure can analyze and obtain the heat fluctuation of the refrigerator compartment during the power-off duration according to the natural temperature change rate, and then obtain the precise fluctuating temperature corresponding to the power-off duration. Therefore, the embodiment of the present disclosure can match the appropriate target ice making amount for the ice making device based on the fluctuating temperature, so that a sufficient amount of ice cubes can be made to offset the heat caused by the temperature rise in the refrigerator compartment during the power-off period, so that the temperature rise phenomenon in the refrigerator compartment can be delayed, which is conducive to ensuring the freshness of the food stored in the refrigerator.

[0049] Optionally, the processor determines the fluctuating temperature of the refrigerator compartment according to the power-off duration of the refrigerator and the natural temperature change rate of the refrigerator compartment, including: when the refrigerator compartment includes a plurality of sub-compartments, the processor calculates T i =a i ×k i ×t, and obtain the corresponding fluctuating temperature T of each sub-chamber i The processor calculates the cumulative value of the fluctuating temperatures of all sub-compartments to obtain the total fluctuating temperature of the refrigerator compartment. i is the correction factor of each sub-compartment, k iis the natural temperature change rate of each sub-compartment, t is the power-off duration of the refrigerator, i=1, 2, ..., n, and n is a positive integer. In this way, considering that there are multiple compartments inside the refrigerator, the embodiment of the present disclosure can set different correction coefficients for each sub-compartment, so as to accurately grasp the configuration differences and heat fluctuation differences of different sub-compartments. Optionally, the correction coefficient can be determined according to the volume of the sub-compartment. Thus, the embodiment of the present disclosure can calculate the corresponding fluctuating temperatures of different sub-compartments during the power-off duration. On this basis, the embodiment of the present disclosure can match the total target ice-making amount of the ice-making device according to the fluctuating temperatures of all sub-compartments to ensure that the ice-making device can make enough ice cubes before the refrigerator is powered off, which is beneficial to ensure the freshness of all food in the refrigerator.

[0050] Optionally, the processor determines the target start time of the ice-making device according to the power-off time of the refrigerator and the target ice-making amount of the ice-making device, including: the processor determines the target ice-making duration of the ice-making device according to the target ice-making amount of the ice-making device; the processor determines the target start time of the ice-making device according to the power-off time of the refrigerator and the target ice-making duration of the ice-making device. In this way, the embodiment of the present disclosure can determine the corresponding target ice-making duration based on the target ice-making amount of the ice-making device, and set a reasonable target start time for the ice-making device in combination with the power-off time of the refrigerator and the target ice-making duration, so as to start the ice-making work at the right time. Therefore, the embodiment of the present disclosure can control the ice-making device to start making ice on time at the target start time, and while ensuring that the ice-making device can make enough ice cubes before the power is cut off in the refrigerator, it can also avoid the ice-making device from making ice cubes too early and maintaining ice cubes to cause energy waste, which is beneficial to the energy-saving operation of the refrigerator.

[0051] Optionally, the processor determines the target start time of the ice-making device according to the power-off time of the refrigerator and the target ice-making time of the ice-making device, including: the processor calculates the difference between the power-off time of the refrigerator and the target ice-making time of the ice-making device to obtain the target start time of the ice-making device. In this way, by subtracting the power-off time of the refrigerator from the target ice-making time of the ice-making device, the embodiment of the present disclosure can obtain a more accurate target start time, so that the ice-making device starts the ice-making work at the most appropriate time and just completes the ice-making work when the refrigerator is powered off. Optionally, a preset time can be subtracted from the above difference, and the newly calculated time value is used as the target start time of the ice-making device, so that a corresponding reserved time can be formed, which fully ensures that the ice-making device can complete the ice-making work before the refrigerator is powered off. Therefore, the embodiment of the present disclosure can make an appropriate amount of ice cubes in advance before the refrigerator is powered off, and can avoid the ice-making device from making ice cubes too early and maintaining ice cubes to cause energy waste, which is conducive to the energy-saving operation of the refrigerator.

[0052] Optionally, the disclosed embodiment may further include more target parameters, not limited to the above target parameters. The target parameters of the ice-making device may also be reasonably set according to the above-mentioned power-off information of the various refrigerators, which are not listed here one by one. At the same time, based on the various target parameters, the ice-making device may make corresponding functional adjustments.

[0053] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0054] S301, the processor obtains power off information of the refrigerator.

[0055] S302: The processor determines target parameters of the ice-making device according to power-off information of the refrigerator.

[0056] S303, the processor obtains food information in the refrigerator compartment.

[0057] S304: The processor corrects target parameters of the ice-making device according to the food information in the refrigerator compartment.

[0058] S305, the processor controls the ice-making device to operate according to the corrected target parameters to make ice cubes before the refrigerator is powered off.

[0059] The target parameters include a target ice making amount and / or a target start time.

[0060] According to the method for controlling a refrigerator provided by the embodiment of the present disclosure, the refrigerator is provided with an ice-making device, which can make ice cubes to maintain the low-temperature storage environment required for food after the refrigerator is powered off. By obtaining the power-off information of the refrigerator, the embodiment of the present disclosure can determine whether the refrigerator will be powered off within the next period of time. If so, the embodiment of the present disclosure further predicts the corresponding ice demand after the refrigerator is powered off, and determines the target ice-making amount and / or target start-up time of the ice-making device accordingly. At the same time, the embodiment of the present disclosure also takes into account the inherent characteristics of food stored in the refrigerator compartment, and reasonably optimizes the ice use demand in combination with the food information, and then adjusts the target ice-making amount and / or target start-up time of the ice-making device. Thereby, the ice-making device can be controlled to operate more accurately, so as to pre-make an appropriate amount of ice cubes before the refrigerator is powered off. On the one hand, the produced ice cubes can be used to delay the temperature rise phenomenon in the refrigerator compartment after the refrigerator is powered off, which is conducive to ensuring the fresh-keeping effect of food stored in the refrigerator. On the other hand, it can avoid consuming more cold energy to maintain ice cubes before the refrigerator is powered off, which is conducive to the energy-saving operation of the refrigerator.

[0061] Optionally, the processor modifies the target parameters of the ice-making device according to the food information in the refrigerator compartment, including: the processor modifies the target parameters of the ice-making device according to the freshness of the food in the refrigerator compartment. In this way, the disclosed embodiment can take into account the problems that may be caused by the freshness of the food, and accordingly modify the target parameters of the ice-making device to make it operate more reliably, so as to make more sufficient ice cubes. In this way, the probability of perishable food spoiling can be effectively reduced when the refrigerator power-off information has an error, which is conducive to improving the reliability of preserving the freshness of this part of food.

[0062] Optionally, the processor obtains the freshness of the food in the refrigerator compartment in the following manner: the processor calculates the difference between the shelf life of the food in the refrigerator compartment and the cumulative storage time, and then calculates the ratio of the difference to the shelf life of the food to obtain the freshness of the food in the refrigerator compartment. In this way, the embodiment of the present disclosure can use the cumulative storage time and shelf life of the food to determine the current freshness of the food. In this way, the freshness of the food can be quantified, which is conducive to reasonably correcting the target parameters of the ice-making device to produce more sufficient ice cubes.

[0063] Optionally, the processor modifies the target parameters of the ice-making device according to the freshness of the food in the refrigerator compartment, including: when the freshness of the food in the refrigerator compartment is less than or equal to the preset freshness, the processor controls the ice-making device to increase the target ice-making amount and / or advance the target start time. In this way, when the freshness of the food in the refrigerator compartment is less than or equal to the preset freshness, it indicates that the cumulative storage time of the food in the refrigerator is long, and the food is less fresh at this time, and it is more likely to deteriorate and spoil. Therefore, the embodiment of the present disclosure can appropriately increase the target ice-making amount of the ice-making device to cope with the situation where the ice cubes are exhausted due to the power failure time. And / or, the target start time of the ice-making device can be appropriately advanced to cope with the situation where the power failure time is advanced and sufficient ice cubes cannot be made. Therefore, the embodiment of the present disclosure can start ice making earlier and make more ice cubes for perishable food, thereby widening the usable period of ice cubes, thereby helping to reduce the probability of perishable food spoiling, and can improve the reliability of keeping the food fresh.

[0064] Optionally, the increase in the target ice-making amount is negatively correlated with the freshness of the food. That is, the lower the freshness of the food, the greater the increase in the corresponding target ice-making amount. In this way, the embodiment of the present disclosure can set a larger target ice-making amount, so that more sufficient ice cubes can be produced. When the power outage duration exceeds the limit, the embodiment of the present disclosure can prevent the ice cubes from running out and causing the low-temperature storage environment required for the food to be unable to be maintained in the second half of the process, and can use the excess ice cubes produced in advance to delay the subsequent temperature rise in the refrigerator compartment, which is beneficial to continuously ensure the freshness of the food stored in the refrigerator.

[0065] Optionally, the advance value of the target start time is negatively correlated with the freshness of the food. That is, the lower the freshness of the food, the greater the advance value of the corresponding target start time. In this way, the embodiment of the present disclosure can set an earlier target start time, thereby leaving more sufficient time for making ice cubes. When encountering a situation where the power outage time is advanced, the embodiment of the present disclosure can prevent the situation where sufficient ice cubes cannot be made within the effective time, resulting in a deterioration in the preservation effect of the food in the later period of the power outage, and can start making ice cubes earlier to fully ensure the smooth completion of the ice making work, which is conducive to ensuring the preservation effect of the food stored in the refrigerator on time.

[0066] Optionally, the processor modifies the target parameter of the ice-making device according to the food information in the refrigerator compartment, including: the processor modifies the target parameter of the ice-making device according to the food price in the refrigerator compartment. In this way, the disclosed embodiment can take into account the problems that may be caused by the food price, and accordingly modify the target parameter of the ice-making device to make it operate more reliably, so as to make more sufficient ice cubes. In this way, the probability of more expensive food spoiling can be effectively reduced when the refrigerator power-off information has an error, which is conducive to improving the reliability of preserving this part of food.

[0067] Optionally, the processor modifies the target parameters of the ice-making device according to the price of the food in the refrigerator compartment, including: when the price of the food in the refrigerator compartment is greater than or equal to the preset price, the processor controls the ice-making device to increase the target ice-making amount and / or advance the target start time. In this way, when the price of the food in the refrigerator compartment is greater than or equal to the preset price, it indicates that the value of this part of the food is high, and if it deteriorates and spoils, the loss caused to the user is large. Therefore, the embodiment of the present disclosure can appropriately increase the target ice-making amount of the ice-making device to deal with the situation where the ice cubes are exhausted due to the power outage timeout. And / or, the target start time of the ice-making device can be appropriately advanced to deal with the situation where the power outage time is advanced and sufficient ice cubes cannot be made. Therefore, the embodiment of the present disclosure can start ice making earlier for more expensive food and make more ice cubes, thereby widening the usable period of ice cubes, thereby helping to reduce the probability of more expensive food spoilage and improve the reliability of keeping these food fresh.

[0068] Optionally, the increase in the target ice-making amount is positively correlated with the price of the food. That is, the higher the price of the food, the greater the increase in the corresponding target ice-making amount. In this way, the embodiment of the present disclosure can set a larger target ice-making amount, so that more sufficient ice cubes can be produced. When the power outage duration exceeds the limit, the embodiment of the present disclosure can prevent the ice cubes from running out and causing the low-temperature storage environment required for the food to be unable to be maintained in the second half of the process, and can use the excess ice cubes produced in advance to delay the subsequent temperature rise in the refrigerator compartment, which is beneficial to continuously ensure the preservation effect of the food stored in the refrigerator.

[0069] Optionally, the advance value of the target start time is positively correlated with the price of the food. That is, the higher the price of the food, the greater the advance value of the corresponding target start time. In this way, the embodiment of the present disclosure can set an earlier target start time, thereby leaving more sufficient time for making ice cubes. When encountering a situation where the power outage time is advanced, the embodiment of the present disclosure can prevent the situation where sufficient ice cubes cannot be made within the effective time, resulting in a deterioration in the preservation effect of food in the later period of the power outage, and can start making ice cubes earlier to fully ensure the smooth completion of the ice making work, which is conducive to ensuring the preservation effect of food stored in the refrigerator on time.

[0070] Optionally, the disclosed embodiment may also include more food information, not limited to the above-mentioned food information. The target parameters of the ice-making device may also be reasonably adjusted according to the above-mentioned food information, which are not listed here one by one. At the same time, based on the above-mentioned multiple target parameters, the ice-making device may make corresponding functional adjustments.

[0071] Specifically, in some embodiments, cakes are stored in the refrigerator compartment. The shelf life of cakes is only one day. When the cumulative storage time exceeds half a day, the freshness of the cakes in the refrigerator compartment is low. To this end, the target ice production amount can be appropriately increased by 10%, and the target start time can be appropriately advanced by 10 minutes. In this way, ice making can be started earlier for perishable ingredients such as cakes, and more ice cubes can be produced, which is conducive to reducing the probability of cake spoilage and improving the reliability of cake preservation.

[0072] Specifically, in some other embodiments, sea cucumbers are stored in the refrigerator compartment. The unit price of sea cucumbers is relatively high. Once they deteriorate and rot, the loss to the user is relatively large. For this reason, the target ice making amount can be appropriately increased by 50%, and the target start time can be appropriately advanced by 30 minutes. In this way, ice making can be started earlier for more expensive ingredients such as sea cucumbers, and more ice cubes can be produced, which is conducive to reducing the probability of sea cucumbers rotting and improving the reliability of sea cucumber preservation.

[0075] S402, the processor controls the operation of the ice-making device according to the power-off information of the refrigerator to make ice cubes before the refrigerator is powered off.

[0076] S403, when the ice cubes are made, the processor sends a usage prompt message.

[0077] The method for controlling a refrigerator provided by the embodiment of the present disclosure is adopted. The refrigerator is provided with an ice-making device, which can make ice cubes to maintain the low-temperature storage environment required for food after the refrigerator is powered off. By obtaining the power-off information of the refrigerator and controlling the ice-making device to operate accurately accordingly, the embodiment of the present disclosure can pre-make an appropriate amount of ice cubes before the refrigerator is powered off. And when the ice-making device completes making ice cubes, a usage prompt message is sent to remind the user to put the ice cubes into the refrigerator compartment in time. Therefore, on the one hand, the embodiment of the present disclosure can use the made ice cubes to delay the temperature rise in the refrigerator compartment after the refrigerator is powered off, which is beneficial to ensuring the preservation effect of food stored in the refrigerator. On the other hand, it can avoid consuming a lot of cold energy to maintain the ice cubes before the refrigerator is powered off, which is beneficial to the energy-saving operation of the refrigerator.

[0078] Optionally, the processor sends the usage prompt information, including: the processor sends the power off information of the refrigerator and the distribution information of the ice cubes to the user's terminal device. In this way, the embodiment of the present disclosure can inform the user of the power off information of the refrigerator, which is conducive to the user to grasp the details of the power outage of the refrigerator, so that the ice cubes can be put into the refrigerator compartment in time at an appropriate time. At the same time, the embodiment of the present disclosure also prompts the user with the distribution information of the ice cubes, which is conducive to the user to distribute the prepared ice cubes to each sub-compartment as needed, thereby meeting the preservation needs of the food stored in different compartments.

[0079] Combination Figure 5 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0080] S501, the processor obtains power off information of the refrigerator.

[0081] S502, the processor controls the operation of the ice-making device according to the power-off information of the refrigerator to make ice cubes before the refrigerator is powered off.

[0082] S503, when the production of ice cubes is completed, the processor records the first temperature in the refrigerator compartment.

[0083] S504, when the refrigerator is powered off and then restored to power, the processor records a second temperature in the refrigerator compartment.

[0084] S505, the processor controls the operation of the refrigerator according to the first temperature and the second temperature to produce cold air for the refrigerator compartment.

[0085] According to the method for controlling a refrigerator provided by the embodiment of the present disclosure, the refrigerator is provided with an ice-making device, which can make ice cubes to maintain the low-temperature storage environment required for food after the refrigerator is powered off. By obtaining the power-off information of the refrigerator and controlling the ice-making device to operate accurately accordingly, the embodiment of the present disclosure can make an appropriate amount of ice cubes in advance before the refrigerator is powered off. On the one hand, the prepared ice cubes can be used to delay the temperature rise phenomenon in the refrigerator compartment after the refrigerator is powered off, which is conducive to ensuring the preservation effect of food stored in the refrigerator. On the other hand, it can avoid the consumption of more cold energy to maintain ice cubes before the refrigerator is powered off, which is conducive to the energy-saving operation of the refrigerator. In addition, when the ice-making device completes the production of ice cubes, the embodiment of the present disclosure also records the first temperature in the refrigerator compartment before the power outage. Then, when the refrigerator is powered off and the power is restored, the embodiment of the present disclosure also records the second temperature in the refrigerator compartment after the power outage. And by analyzing the first temperature and the second temperature before and after the power outage, the embodiment of the present disclosure further controls the refrigerator to operate accurately, so as to quickly make cold air to the refrigerator compartment after the power is on, which is conducive to restoring the low-temperature storage environment required for food in the refrigerator compartment.

[0086] Optionally, the processor controls the operation of the refrigerator according to the first temperature and the second temperature, including: the processor determines the operating parameters of the refrigerator according to the difference between the second temperature and the first temperature; the processor controls the refrigerator to operate the refrigeration mode according to the operating parameters. The operating parameters include part or all of the compressor frequency, the fan speed, and the throttle valve opening. In this way, the embodiment of the present disclosure can judge the actual heat fluctuation in the refrigerator compartment during the power outage according to the temperature difference before and after the refrigerator is powered off, and adjust the operating parameters of the refrigerator accordingly. The greater the difference between the second temperature and the first temperature, the more serious the adverse effect of the heat in the refrigerator compartment on the food. To this end, the embodiment of the present disclosure controls the refrigerator to operate a more intense refrigeration mode, so that more cold air can be quickly produced in the refrigerator compartment, which is conducive to timely restoring the low-temperature storage environment required for the food in the refrigerator compartment.

[0087] Optionally, when the refrigerator compartment includes multiple sub-compartments, the first temperature and the second temperature corresponding to each sub-compartment can be recorded respectively with reference to the above steps, and the corresponding refrigeration parameters of each sub-compartment can be determined accordingly, and then the refrigerator can be controlled to operate the refrigeration mode according to the multiple refrigeration parameters to produce cold air for each sub-compartment respectively. In this way, the corresponding heat fluctuation differences in different sub-compartments during the power outage can be reasonably analyzed, and by adapting the corresponding refrigeration parameters, each sub-compartment can restore the low-temperature storage environment required by the food as soon as possible.
