In some embodiments, in the refrigerator 100 of the embodiment of the present invention, the thawing area 104 is disposed adjacent to the freezing compartment 103, thereby facilitating movement of the rack 200 between the thawing area 104 and the freezing compartment 103. As shown in fig. 1, there are two storage compartments, a freezing compartment 103 is provided below a refrigerating compartment 102, and a thawing area 104 is formed in a lower area of the refrigerating compartment 102 above the freezing compartment 103. As shown in fig. 2, four storage compartments are provided, namely, an upper refrigerating compartment 102, a lower freezing compartment 103, and a middle two freezing compartments 103 arranged in the left-right direction, and a thawing area 104 is formed in the lower area of the refrigerating compartment 102 and above the middle two freezing compartments 103.

In the embodiment shown in fig. 1, the rack 200 has one. In the embodiment shown in fig. 2, there are two racks 200, each disposed in the middle two freezing compartments 103. It will be appreciated that a plurality of racks 200 may be provided in the same freezing chamber 103 to hold the same or different kinds of food.

The refrigerator 100 of the embodiment of the present invention is configured to: receiving a defrosting instruction sent by a user, the rack 200 is controlled to move from the freezing compartment 103 into the defrosting area 104. The defrosting instruction issued by the user may be, for example, "immediately start defrosting XX food material", "start defrosting XX food material after XX time", "use XX food material after XX time", or the like. The refrigerator 100 provided by the embodiment of the invention can realize reservation thawing based on the instruction of the user, and improves the use experience of the user.

In some embodiments, the thawing instructions include the type of food material to be thawed and the expected time of use of the food material. The refrigerator 100 of the embodiment of the present invention is configured to:

determining the types of the food materials to be thawed and the racks 200 corresponding to the expected use time of the food materials and the time required for thawing according to a preset first mapping relation, wherein the types of the food materials to be thawed, the racks 200 corresponding to the expected use time of the food materials and the time required for thawing are specified in the first mapping relation; and

the thawing open time is calculated according to the expected time for using the food and the time required for thawing, and the rack 200 is controlled to move from the freezing compartment 103 into the thawing area 104 during the thawing open time.

For example, the refrigerator 100 has two racks 200, including a first rack and a second rack. The rack 200 corresponding to pork is a first rack 200. The expected time of use of the food material was assumed to be 17 points for 30 minutes. In the first mapping relationship, the time required for thawing of pork and food materials at 17 points and 30 minutes is expected to be 1h. The difference between the expected time of using the food material and the time required for thawing was calculated to give a thawing open time of 16 points and 30 minutes. At 16 points 30 minutes, rack number one 200 is moved from freezer compartment 103 into thawing area 104. For another example, the rack 200 corresponding to the steak is a rack No. 200. The expected time of use of the food material was assumed to be 18 points and 30 minutes. In the first mapping relationship, the time required for thawing the steak, which corresponds to 30 minutes at 18 points of the expected food material use time, is 30 minutes. And calculating the difference between the expected food material using time and the time required for thawing, and obtaining the thawing opening time of 18 points and 0 point. At point 18, 0 hours, rack number two 200 is moved from freezer compartment 103 into thawing area 104.

the control rack 200 moves from the freezer compartment 103 into the defrost region 104 at the defrost initiation time.

For example, the refrigerator 100 has two racks 200, including a first rack and a second rack. Assume that the rack 200 corresponding to pork is the rack 200 No. one. Assuming that the defrosting instruction issued by the user is "immediately start defrosting pork", the defrosting start time is determined as the current time, and the rack No. 200 immediately moves from the freezing compartment 103 into the defrosting area 104. Assuming that the defrosting instruction issued by the user is "defrosting pork after 30 minutes", the defrosting start time is determined to be the sum of the current time and 30 minutes, and the rack No. 200 is moved from the freezing compartment 103 into the defrosting area 104 after 30 minutes.
