In general, the carrier liquid is at normal temperature, so that the frozen food 500 can be gradually warmed to defrost. Because the frozen food 500 and the cold carrier liquid are stored in the two different cavities capable of exchanging heat, the loss of nutrition caused by the dissolution of soluble substances in the food, such as water, protein and the like, in the cold carrier liquid can be avoided, so that the nutrition components and the taste of the food are better reserved.

In the thawing box 200, the cold carrier liquid exchanges heat with the frozen food 500 in the thawing cavity 210, the cold carrier liquid conducts heat to the frozen food 500, so that the frozen food 500 is heated to realize thawing, the temperature of the cold carrier liquid is reduced, the cold carrier liquid exchanges heat with the outside air after flowing back into the liquid storage box 100, the outside air conducts heat to the cold carrier liquid, so that the cold carrier liquid is heated again and flows to the liquid storage cavity 220, and thus the circulation can improve the heat exchange efficiency between the cold carrier liquid and the frozen food 500, thereby improving the thawing rate, shortening the thawing time and realizing rapid thawing.

It will be appreciated that the circulation driving mechanism 300 may also include a pressure mechanism and a check valve, wherein when the check valve is mounted on the liquid outlet pipe 120, the flow direction of the check valve faces the liquid storage cavity 220, and when the check valve is mounted on the liquid inlet pipe 110, the flow direction of the check valve faces the liquid storage box 100.

When the frozen food 500 is placed in the thawing chamber 210, the frozen food 500 can be more attached to the inner wall of the thawing chamber 210, so that the heat exchange area is increased, on one hand, the heat exchange efficiency between the cold carrier liquid and the frozen food 500 is improved, and the thawing rate is further improved, and on the other hand, the frozen food 500 can be uniformly thawed, and the thawing rate is further improved.

Referring to fig. 2 and 3, it can be appreciated that the thawing box 200 is detachably connected to the liquid inlet pipe 110 and the liquid outlet pipe 120. Specifically, in the thawing box 200, the upper ends of the two liquid passing channels 270 are respectively provided with an abutment 271, the liquid inlet pipe 110 and the liquid outlet pipe 120 are respectively in plug-in fit with the two abutments 271, or the ends of the liquid inlet pipe 110 and the liquid outlet pipe 120 are respectively provided with connectors in threaded fit with the abutments 271, so that the liquid inlet pipe 110 and the liquid outlet pipe 120 are respectively communicated with the two liquid passing channels 270 in a threaded connection manner.

On the one hand, after the thawing is completed, the thawing box 200 can be disassembled to facilitate cleaning of the inner shell 230 of the thawing box 200, and on the other hand, when thawing is not needed, the thawing box 200 can be disassembled to be stored, so that the space of the refrigerating chamber 410 or the temperature changing chamber 420 is not occupied, and the space utilization rate of the refrigerator is improved.

Referring to fig. 2 to 4, it can be understood that a pipe fixing member 130 is disposed between the liquid inlet pipe 110 and the liquid outlet pipe 120, specifically, the pipe fixing member 130 is located near one end of the liquid inlet pipe 110 and the liquid outlet pipe 120 connected to the thawing box 200, the pipe fixing member 130 is provided with two through holes 132, the central lines of the two through holes 132 are parallel, and the liquid inlet pipe 110 and the liquid outlet pipe 120 respectively penetrate through the two through holes 132 and are fixedly connected with the pipe fixing member 130, for example, the liquid inlet pipe 110 and the liquid outlet pipe 120 are bonded with the pipe fixing member 130, or are in interference fit.

Generally, the surface temperature of the frozen food 500 is far lower than the temperature of the refrigerating compartment 410 or the temperature changing compartment 420, and thus, the temperature of the refrigerating compartment 410 or the temperature changing compartment 420 can be set as the reference temperature, and if the temperature detector 250 detects that the temperature is lower than the reference temperature, it can be determined that the frozen food 500 exists in the thawing chamber 210.

It will be appreciated that the controller is provided with a target temperature parameter, typically set to-3 ℃, which is also typically lower than the reference temperature, i.e., the surface temperature of the frozen food 500 after thawing is completed. It is easily understood that frozen food 500 such as frozen meat at-3 c is easily cut and can well retain nutrition and mouthfeel. In the process of thawing frozen food 500, temperature detector 250 monitors the surface temperature of frozen food 500 in real time, when temperature detector 250 detects that the surface temperature of frozen food 500 reaches the target temperature, then feeds back the second temperature signal to the controller, and the controller controls circulation driving mechanism 300 to stop according to the second temperature signal, thereby stopping thawing, avoiding nutrient loss caused by excessive thawing, and solving the problem that a user cannot judge whether the thawing state is easy to cut or not, and being convenient to use.

Referring to fig. 2 to 4, it can be understood that, specifically, an extension 131 is provided at an end of the pipe fixing member 130 facing the thawing box 200, the extension 131 is provided downward, and the temperature detector 250 is mounted at a lower end of the extension 131. When the thawing box 200 is connected to the liquid inlet pipe 110 and the liquid outlet pipe 120, the extension part 131 can extend into the thawing chamber 210, and the temperature detector 250 is disposed in the thawing chamber 210, so that the temperature detector 250 can monitor the surface temperature of the frozen food 500 in the thawing chamber 210.

Referring to fig. 2 and 4, it can be appreciated that, in order to facilitate the closing of the cover 260, the cover 260 is provided with a relief groove 261, and the extension 131 is penetrated through the relief groove 261 so that the extension 131 can be relieved.

It can be appreciated that the temperature detector 250 may be directly mounted on the inner wall of the thawing chamber 210, and since the thawing box 200 is detachable, only a first connection terminal connected to the temperature detector 250 needs to be added on the thawing box 200, and a second connection terminal matched with the first connection terminal is disposed inside the refrigerator, so that the first connection terminal and the second connection terminal are separated when the thawing box 200 needs to be detached.
