All-temperature-changing frost-free refrigerator

Abstract

The invention discloses an all-temperature-changing frost-free refrigerator. The all-temperature-changing frost-free refrigerator comprises at least two chambers, wherein a lower chamber air-feeding duct for air feeding of the lower chamber and a lower chamber air return duct for air returning of the lower chamber are arranged at the back of the lower chamber; a lower chamber air-feeding door is arranged in the lower chamber air-feeding duct; a lower chamber air return door is arranged in the lower chamber air return duct; air feeding ducts are arranged at the back of all other chambers except for the lower chamber of the refrigerator and used for feeding air into the corresponding chambers; one end of each air feeding duct communicates with the upper part of an evaporator chamber, and the other end of each air feeding duct communicates with the corresponding chamber; an independent air feeding door is arranged in each air feeding duct; and by controlling the air feeding doors corresponding to the chambers to be opened and closed, the distribution of cooling capacity of all the chambers is realized, so that temperature adjustment of all the chambers can be controlled. The all-temperature-changing frost-free refrigerator has the advantage that all the chambers of the refrigerator have the temperature changing function.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a fully variable temperature air-cooled refrigerator. Background technique [0002] In the existing refrigerators, the variable temperature zone is only realized as an incidental function of the refrigerator, and the volume is limited. With the improvement of people's living standards, there are more and more types of items that need to be stored, and the suitable storage temperature for different items The temperature zone is also different, and the small volume variable temperature zone is difficult to meet the individual needs of users. [0003] In ordinary temperature-variable refrigerators, the temperature-variable zone is generally set in a small compartment in the middle of the refrigerator, or within a limited area in the lower part of the refrigerator, but the defects of this product are also obvious.

Problems solved by technology

[0002] In the existing refrigerators, the variable temperature zone is only realized as an incidental function of the refrigerator, and the volume is limited. With the improvement of people's living standards, there are more and more types of items that need to be stored, and the suitable storage temperature for different items The zones are also different, and the small-volume temperature-variable zone is difficult to meet the individual needs of users.

[0003] In ordinary variable temperature refrigerators, the variable temperature zone is generally set in the small room in the middle of the refrigerator, or in the limited area of ​​the lower part of the refrigerator, but the defects of this product are also obvious

Setting up a small room alone as a variable greenhouse not only has a very limited capacity, but also generally has two methods in order to isolate this room from other rooms. One of the common methods is to use a separate refrigerator liner and The other compartments are isolated and insulated, which obviously increases the process steps in the production process and increases the difficulty of assembly, and the design of the air supply system is also relatively complicated, and the production cost is also high; The partition is isolated from other compartments, but the defect of air leakage at the assembly point is difficult to avoid, and the larger the volume of the compartment, the more obvious the air leakage, the assembly is complicated, and the design of the air supply path is also complicated;

[0004] In addition, it is also possible to realize the temperature changing function of the entire compartment of the refrigerator by adopting the design of multiple refrigeration systems, but the realized temperature changing function is still limited.
