Fig. 4 is a schematic diagram of a method for thawing stored objects in a refrigerator according to an embodiment of the present invention, and the method for thawing stored objects in a refrigerator can be implemented by using the refrigerator 100 of any of the above-mentioned embodiments. As shown in the figure, the thawing method of the refrigerator stores performs the following steps in sequence:

Step S402, obtaining the thawing information of the stored items in the independent compartment 11 and the thawing time set by the user;

Step S404, respectively estimating the estimated time required for thawing using different thawing methods according to the thawing information;

Step S406, matching the set thawing time with the estimated time of different thawing methods to select a thawing method that meets the thawing time requirement;

If the current time is 16:40, and the user needs to use the storage for cooking at 17:00, the set thawing time should be If it is 20 minutes, you can only choose to use the ambient heat and the heat released by the bypass condenser 12 to combine thawing, and you can start thawing at 16:50, so that you can just complete the thawing at 17:00, which will not delay the user's use.

In step S616, the thawing process of using the ambient heat of the refrigerator and the heat released by the bypass condenser 12 combined with the thawing process can be as follows: open the door body of the independent compartment 11 and turn on the fan 22 in the independent compartment 11, and simultaneously turn on the It is used to control the solenoid valve of the bypass condenser 12 to simultaneously use the convective air and the heat released by the bypass condenser to defrost the storage.

In step S618 , the prompt information indicating that the storage time is insufficient for thawing can be output by a display device of the refrigerator 100 or a mobile terminal connected with the refrigerator 100 by data.

According to the above process, if the thawing time set by the user is met, the heat of the environment where the refrigerator is located can be preferentially used for thawing. If the heat of the environment where the refrigerator is used for thawing cannot meet the requirements, the heat released by the bypass condenser 12 can be used alone Thawing, if still can not meet the requirements, you can use the ambient heat of the refrigerator and the heat released by the bypass condenser 12 to thaw together, so as to thaw with less energy consumption and less impact on the storage.

A specific example is introduced as follows:

A piece of beef in the freezer compartment needs to be used for cooking at 17:00, and it needs to be thawed, and the current time is 16:20, then it can be concluded that the thawing time set by the user is 40 minutes. After taking out the beef, put it on the tray 19 of the independent compartment 11, use the weight sensor and temperature sensor at the bottom of the tray 19 to obtain its weight as 500 grams, and the temperature is -10 degrees Celsius, and according to the thawing information in the preset thawing Matching in the schedule shows that the first estimated time required for thawing using the heat of the environment where the refrigerator is located is 60 minutes, the second estimated time required for thawing using the heat released by the bypass condenser 12 is 30 minutes, and using the environment The heat and the heat released by the bypass condenser 12 combined with the third estimated time required for thawing is 10 minutes. This calculates that this beef utilizes the scheduled start time of thawing of refrigerator place environment heat to be 16:00; Utilize the scheduled start time of thawing of the heat that bypass condenser 12 releases to be 16:30; The scheduled start time for heat combined with thawing is 16:50. Since the current time 16:20 is later than 16:00, it is not possible to use the heat of the environment where the refrigerator is located to thaw, so as not to thaw the beef completely and affect the cooking effect. The current time 16:20 is earlier than 16:30, so the heat released by the bypass condenser 12 can be used to thaw, and the thawing can be started when the current time reaches 16:30, so that the thawing can be completed at 17:00, without delaying the user Carry out cooking, avoid the non-refrigerated state of beef after thawing again and go bad. This embodiment is only an illustration of the method for thawing the refrigerator storage in this embodiment. In actual use, various types of storage can be thawed according to specific needs, and the specific estimated time may also be based on the configuration of the refrigerator. However, there are differences, and the above specific numerical values are not intended to limit the present invention.

In addition, it provides users with a variety of thawing methods, according to user settings Choose the thawing method according to the specific thawing time, so that the stored items will not deteriorate due to premature thawing, and will not affect the user's use due to too late thawing, so as to meet the various needs of users and improve the user experience.

Further, in the method for thawing stored items in a refrigerator in this embodiment, after driving the independent compartment 11 to execute the thawing process corresponding to the selected thawing mode, the thawing temperature of the stored items can be obtained, and when the thawing temperature is greater than or equal to the preset value Stop thawing; and send prompt information to the user through the mobile terminal, and receive the control command returned by the mobile terminal to end the thawing process and start refrigeration in response to the prompt information. The stored items in the refrigerator can be removed or restarted to refrigerate, which can avoid the situation that the thawed stored items are forgotten and deteriorated. The method of thawing the stored items in the refrigerator is more convenient, which improves the user experience.
