Please refer to Figure 1 and Figure 2, Figure 2 is an exploded view of the drawer container 20 in the refrigerator 1 according to an embodiment of the present invention. In some other specific embodiments, the food processing device 30 can also be indirectly arranged in the refrigerator In the storage compartment 12 of. The refrigerator 1 may further include a drawer-type container 20 configured to be operatively pulled out or retracted into the storage compartment 12, wherein the food processing device 30 is arranged such that its carrier plate 100 serves as a drawer-type container 20. bottom plate.

The loading plate 100 is used to support the food materials to be processed. The loading plate 100 can also be configured as a soaking plate. The soaking plate can be made of a metal with relatively strong thermal conductivity (such as metal copper, etc.), and the inside of the soaking plate has a plurality of The vacuum heat exchange chamber 110 extending in parallel is filled with a heat exchange medium, and the heat exchange medium can be pure water.

The temperature adjustment module 200 is disposed on the bottom of the loading plate 100, and is used to controlly provide cold or heat to the loading plate 100 and the food to be processed.

The heat pipe 300 is connected to at least part of the periphery of the carrier plate 100, and is arranged along a direction perpendicular to the plurality of vacuum heat exchange chambers 110. The heat pipe end of the heat pipe 300 is close to the temperature adjustment module 200, so as to absorb the heat emitted by the temperature adjustment module 200 through the carrier plate 100. heat, and transfer the heat to its cold end, and then transfer the heat along the extending direction of the plurality of vacuum heat exchange chambers 110 .

Since the pressure in the vacuum heat exchange chamber 110 is small (in a vacuum or close to a vacuum state), the evaporation temperature of the heat exchange medium is lower than the normal evaporation temperature. When a certain area of the vapor chamber is heated, the vacuum heat exchange chamber 110 The heat exchange medium evaporates in a vacuum environment to form gaseous steam and absorbs heat at the same time. When the gaseous steam encounters a colder area in the vacuum heat exchange chamber 110, it condenses into a liquid state and releases heat, thereby realizing heat transfer.
