Embodiment Construction
[0032] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only some, but not all, embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.
[0033] In the related art, the changing room 3 is embedded in the freezing room 2 or the refrigerating room 1. When the temperature difference between the changing room 3 and the freezing room 2 or the refrigerating room 1 is large, due to heat conduction, the side with the higher temperature will be separated. If the room temperature is too low, for refrigeration, ...

The invention provides an auxiliary heat exchange device and a refrigerator. The auxiliary heat exchange device comprises a partition plate, wherein the partition plate is arranged between a variable-temperature chamber and a storage chamber; and a thermoelectric refrigeration device is arranged in the partition plate and is configured to carry heat in the variable-temperature chamber to the storage chamber or carry heat in the storage chamber to the variable-temperature chamber when currents in different directions are introduced. According to the auxiliary heat exchange device, the thermoelectric refrigeration device is arranged in the partition plate between the variable-temperature chamber and a refrigerating chamber or between the variable-temperature chamber and a freezing chamber, auxiliary heat exchange is carried out by conducting a forward current or a reverse current to the thermoelectric refrigeration device, the problem that when the temperature difference between the two chambers is too large, the temperature of the high-temperature chamber is uncontrollably too low due to heat conduction is solved, rapid adaptation is realized when the set temperature of the variable-temperature chamber is greatly changed, and a fresh-keeping environment for food is guaranteed.
Description
technical field [0001] The present disclosure belongs to the technical field of refrigerators, and in particular relates to an auxiliary heat exchange device and a refrigerator. Background technique [0002] With the continuous development of the refrigerator industry, the functions of refrigerators are becoming more and more abundant. Now many refrigerators are equipped with changing greenhouses in the refrigerating room or freezing room. Set to refrigerator temperature or freezer temperature as required. It is equivalent to a variable compartment volume. When the volume of the refrigerator compartment is insufficient, it can be set as a refrigerator compartment, and when the volume of the freezer compartment is insufficient, it can be set as a freezer compartment. [0003] However, when the difference between the changing room and the refrigerating room or the freezing room is large, due to the existence of heat conduction, the temperature of the higher temperature room w...
