Abstract

The present invention provides a refrigerator which achieves temperature equalization in a refrigerating chamber without promoting drying of food and is provided with: a first refrigerating temperature zone chamber; a second refrigeration temperature zone chamber; a freezing temperature zone chamber; the first cooler is arranged on the back of the first refrigeration temperature zone chamber; thefirst air blower is used for supplying cold air of the first cooler to the first refrigeration temperature zone chamber; a first air path flowing from the first cooler through the first refrigerationtemperature zone chamber and returning to the first cooler; the second cooler is arranged on the back of the freezing temperature zone chamber or the second refrigerating temperature zone chamber; thesecond air blower is used for supplying cold air of the second cooler to the freezing temperature zone chamber or the second refrigerating temperature zone chamber; the refrigerator is characterizedin that an output opening of the first air path is not formed in the front surface of the first refrigeration temperature zone chamber, and main flow cold air from the first cooler goes to the wall face in the first refrigeration temperature zone chamber.

Description

technical field [0001] The present invention relates to refrigerators. Background technique [0002] In a normal refrigerator, a refrigerator compartment, a freezer compartment, a vegetable compartment, etc. have different appropriate storage temperatures depending on the foods to be stored, so a plurality of storage compartments are provided, and among them, the refrigerator compartment is designed to be the largest in many cases. Therefore, in the refrigerator compartment, the temperature distribution of the cold air in the cooling box tends to be uneven. Therefore, as shown in Patent Document 1, a cold air circulation fan is provided in the refrigerator compartment box, and the temperature uniformity in the refrigerator compartment is achieved.
