Refrigerator

Abstract

The invention discloses a refrigerator which comprises a freezing chamber and at least one temperature-changing chamber and is internally provided with a finned evaporator, a fan and temperature sensors, wherein the finned evaporator is arranged on the rear wall of the temperature-changing chamber or / and the freezing chamber; the fan is arranged beside the evaporator and used for providing the cold air of the evaporator for an indoor room; and the temperature sensors are arranged in the temperature-changing chamber and the freezing chamber. The temperature-changing chamber or / and the freezing chamber of the refrigerator of the invention has / have strong refrigerating effect and can enable foods to be rapidly frozen through an ice crystal area at the temperature of -1 to -5 DEG C, thereby the original freshness and the nutrient components of the foods are kept to be not lost; the foods are kept to be stored at the low temperature of -30 DEG C, thereby the storage time of the foods is prolonged.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a refrigerator. Background technique [0002] For traditional three-door refrigerators, there are generally refrigerating chambers, freezing chambers and temperature-changing chambers. Under normal circumstances, the refrigerator is placed for short-term storage of food, and the food placed in the freezer and the middle door variable temperature room can be stored for a longer period of time. However, according to daily habits, most foods do not require long-term storage. Under normal circumstances, the ice crystal area of ​​food is between -1°C and -5°C, and the food in the ice crystal area will become lumpy. The food placed in the freezer of the traditional refrigerator and the variable temperature room are all formed during the gradual freezing process. The block granular crystals, which destroy food nutrition, and increase a certain amount of energy consumption. If you ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the above-mentioned refrigerator makes the freezing process gradual, and this gradual freezing method makes the freezing process stay in the ice crystal area for the longest time, and relatively large block granular crystals are formed inside the food, which destroys the nutrition of the food and affects the quality of the food. fresh-keeping effect
