Refrigerator and unfreezing method for refrigerator

Abstract

The invention discloses a refrigerator and an unfreezing method for the refrigerator. The refrigerator comprises a freezing chamber, a variable-temperature chamber and a refrigerating chamber which are arranged from bottom to top; an unfreezing chamber is further arranged above the refrigerating chamber, and the unfreezing chamber and the refrigerating chamber are separated through a thermoelectric refrigerating plate; and the thermoelectric refrigerating plate comprises a cold end, a heat insulation layer and a hot end, the cold end and the hot end are separated through the heat insulation layer, an aluminum base plate heat conduction insulating layer is arranged on the surface of the hot end, the hot end and the unfreezing chamber are separated through the aluminum base plate heat conduction insulating layer, and the aluminum base plate heat conduction insulating layer is further provided with cooling fins. According to the refrigerator, the hot end of the thermoelectric refrigerating plate is used for heating, and thus the purpose of unfreezing food in the unfreezing chamber is achieved; the structure is simple, the unfreezing efficiency is high, and the structure of the food itself can not be damaged; and meanwhile, the refrigerating capacity discharged from the cold end of the thermoelectric refrigerating plate can play a role in compensation at a certain degree for a refrigerator refrigerating system, and the energy efficiency is improved.

Description

technical field [0001] The invention relates to the field of refrigerator manufacturing, in particular to a refrigerator and a thawing method for the refrigerator. Background technique [0002] Refrigerator is a food storage device commonly used in families at present. However, in actual use, especially when cooking, it is a problem to quickly thaw the meat taken out of the freezer. [0003] The more popular thawing products on the market are thawing boards. The survey found that most families would not buy thawing boards alone, and thawing food quickly will affect its taste; [0004] The proposed implementation methods of refrigerators with a thawing chamber can be roughly divided into the following categories: [0005] 1. Direct heating, such as electric heating, heating wire, heat pipe; [0006] 2. Wind circulation, the hot air in the refrigerator is introduced into the thawing device to blow on the food that needs to be thawed; [0007] 3. Electromagnetic wave oscilla...

Problems solved by technology

[0010] Among the above-mentioned solutions, the direct heating of Option 1 is often too high in temperature, which is easy to damage the internal structure of the food and cause nutrient loss; Option 2 to 5 have high costs and are very complicated to implement, and the existing structure of the refrigerator has been greatly changed and the cost is relatively high.
