Energy-saving refrigerator and fast unfreezing method and system thereof

Abstract

The invention relates to the field of refrigerator devices and discloses an energy-saving refrigerator. The energy-saving refrigerator comprises a refrigerating chamber and a variable-temperature chamber, wherein the variable-temperature chamber is provided with a variable-temperature evaporator and a variable-temperature fan; a circulating air duct is formed between the refrigerating chamber andthe variable-temperature chamber by an air supply duct and an air return duct; an air door is arranged on the air supply duct; and when the refrigerating chamber needs to refrigerate or the variable-temperature chamber needs to be heated up for unfreezing, the variable-temperature fan is started and the air door is opened to make the circulating air duct through so as to form convective heat exchange. By use of the energy-saving refrigerator, energy in both of the refrigerating chamber and the variable-temperature chamber can be reasonably utilized to realize fast unfreezing of frozen food inthe variable-temperature chamber, the energy consumption of the complete machine is not increased during refrigeration of the refrigerating chamber, and thus, the product material cost is reduced.

Description

technical field [0001] The invention relates to the field of refrigerator equipment, in particular to an energy-saving refrigerator and its fast thawing method and system. Background technique [0002] Refrigerator is a kind of refrigeration equipment that maintains a constant low temperature, which brings convenience to food preservation. When the food temperature reaches the freezing temperature (such as ≤-18°C), it can prolong the preservation time of food, so meat, fish, etc. need to be preserved for a long time The food for a long time is often placed in the freezer or the changing room (at this time the changing room reaches the freezing temperature), but due to the low temperature of the freezing room, the internal moisture of the meat, fish and other foods placed in the freezing or changing room has been frozen, and cannot Use immediately for cooking, need to thaw first. General user thawing schemes are as follows: [0003] The first is to take out the frozen food ...

AI Technical Summary

Problems solved by technology

[0005] The third is to put the food that needs to be thawed into the refrigerator. The pain point is that the refrigerator needs to have available space, and it needs to be transported manually. It takes a long time to thaw, which is laborious and laborious.

Moreover, the adjacent rooms are normally refrigerated, but the variable temperature room needs heaters to be heated. The variable temperature heater consumes electricity and wastes energy. Increased overall energy consumption
