The inside of the freezing drawer 200 may be provided with a detecting device 240, and the detecting device 240 is used for detecting the food material amount of the food material. During freezing, the supply time of the refrigerating air flow can be controlled according to the food amount of the food material, so that after the food material is completely frozen, the supply of the refrigerating air flow is stopped; during thawing, the supply time of the thawing air flow may be controlled according to the amount of the food material so that the supply of the thawing air flow is stopped after the food material is completely thawed. Therefore, the supply time of the refrigerating air flow or the thawing air flow can be reasonably controlled, the surface of the food material is prevented from being air-dried, and the freezing or thawing quality of the food material is guaranteed.

In one example, the detecting device 240 may be an ultrasonic sensor, which may be fixed to a top wall of the drawer outer tub 210 or a side wall of the drawer main body 220, and indirectly determine the amount of food material by transmitting ultrasonic waves to the food material and performing echo detection on the ultrasonic waves, by determining position information, height information, etc. of the food material.

The refrigerator 10 has the functions of freezing and thawing, and a user can finish thawing food materials in advance by manually starting the thawing function or remotely starting the thawing function without waiting for a long time. The defrosting heat energy is derived from the external environment or hot air in the press bin, auxiliary heating equipment such as a heating pipe and the like is not needed, and the defrosting cost is reduced.

The refrigerator 10 of the present utility model may further have an identification function, after thawing, a user may forget to take out the food material, and if the user finds that the food material is not taken out within a preset period of time, the user may automatically determine that thawing is abandoned, and open the freezing function again, so as to avoid deterioration of the food material in a thawing state for a long time.

Since the inside of the drawer main body 220 is normally in a low-temperature frozen state only for a short high-temperature period during thawing, the drawer main body 220 does not need to be cleaned immediately after use, food residues in the drawer main body 220 are not deteriorated, and the use complexity is reduced.
