Abstract

A refrigerator has a storage compartment (3) for cooling and storing articles, a cooler (5) for generating cool air, a discharge passage (20) allowing the cool air generated by the cooler (5) to flow along the rear surface of the storage compartment (3) and having a discharge opening (20c) for discharging the cool air, a return passage (23) placed parallel to the discharge passage (20), having return openings (23a, 23b) into which the cool air flows from the storage compartment (3), and allowing the cool air flowing from the return ports (23a, 23b) to return to the cooler (5), and a member (27) formed of a good thermal conductor disposed on those sides of the discharge passage (20) and the return passage (23) which face the storage compartment (3). The discharge passage (20) and the return passage (23) are merged together on the downstream side of the return ports (23a, 23b).

Description

technical field [0001] The present invention relates to a refrigerator having a discharge passage for discharging cold air generated by a condenser into a storage room and a return passage for returning cold air from the storage room to the condenser. Background technique [0002] Patent Document 1 discloses a conventional refrigerator. Figure 9 , Figure 10 It is a front cross-sectional view and a side cross-sectional view showing a schematic configuration of the refrigerator. The refrigerator 1 is provided with a freezer compartment 2 at the top, and a refrigerator compartment 3 is provided below the freezer compartment 2 . The freezing compartment 2 and the refrigerating compartment 3 are separated by a partition wall 4 filled with an insulating material. The front of freezer compartment 2 is opened and closed by door 2a, and the front of refrigerator compartment 3 is opened and closed by door 3a. [0003] A condenser 5 for generating cold air is disposed on the back ...
