Refrigerator with cold storage function

Abstract

The invention discloses a refrigerator with a cold storage function and relates to the technical field of refrigerating equipment. The refrigerator is characterized in that inner liners are arranged in a heat preservation layer; gel coolant layers are arranged between the inner liners and the heat preservation layer; all low-temperature heat transfer pipes are uniformly distributed on the outer side surfaces of the inner liners; the gel coolant layers adhere to the outer side surfaces of the inner liners, and closely cling to the outer side walls of all the low-temperature heat transfer pipes; and two pieces of aluminum foil adhesive tape are arranged on the outer surfaces of the gel coolant layers and cover the whole gel coolant layers. The refrigerator disclosed by the invention has the ultra-long-time cold storage function under the premise that the effective volume of the refrigerator is not occupied; through the combined action of the inner liners made of a metal material, the gel coolant layers and the heat preservation layer, the ultra-long-time cold storage function is achieved, food is protected from spoilage and flavor reversion caused by long-time power outage, and the refrigerating capacity utilization ratio of the refrigerator is prevented from being reduced; and through the low-temperature heat transfer pipes, instantaneous heat transfer is achieved, and a conventional single-sided cold supply process is converted into a multi-sided simultaneous cold supply process, thereby achieving extremely uniform temperature in the refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator for storing food. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common household appliance used for low-temperature preservation of food or other items in daily life. Most of the existing refrigerators do not have the cold storage function. In the event of a long-term power outage, the refrigerator cannot maintain a low-temperature environment, which will easily cause the stored food to deteriorate. In order to solve this problem, some manufacturers equip the refrigerator freezer with bagged or canned coolant, which can delay the temperature rise in the refrigerator to a certain extent after the refrigerator is powered off, but it still cannot solve the problem of temperature rise in the refrigerator freezer. Still faster problem. At the same time, the cold storage agent o...

Problems solved by technology

[0012] The technical problem to be solved by the present invention is to provide a refrigerator with a cold storage function to overcome the problem that the existing refrigerators do not have the cold storage function, and the stored food is likely to deteriorate in case of a long-term power failure. It is not ideal, and it occupies the effective volume of the refrigerator, resulting in the reduction of the cooling utilization rate of the refrigerator and the uneven temperature in the refrigerator, which is not conducive to food preservation.
