Problems solved by technology

However, when the sealing performance deteriorates due to the deterioration of the sealing member 24 over time, the cold air cannot be blocked, and the cold air in the freezer compartment 25 is heated due to the heat exchange with the high-temperature metal receiving member 14, thereby reducing the cooling efficiency. Lowering the problem

Abstract

A refrigerator according to the present invention uses partition wall (118) that divides the interior of a heat-insulating box into a plurality of storage compartments, to which cool air is supplied, and includes openable door (105a) in front of each of the storage compartments. On door (105a), door gasket (124) is provided which is in tight contact with metal receiving member (123) that is provided on the front face facing the doors, of partition wall (118). The storage compartments include storage cases. A configuration such that metal receiving member (123) is heated is provided. Heat exchange suppression space (140) is also provided which suppresses heat exchange between cool air in the associated storage compartment and metal receiving member (123).

Description

technical field [0001] The present invention relates to a structure of a refrigerator having a high energy-saving effect. Background technique [0002] Figure 11 It is a sectional view of the basic structure of the freezer of the conventional refrigerator. [0003] Such as Figure 11 As shown, a door gasket 12 is provided over the entire circumference at the end portion of the inner surface of the door 11 . The metal receiving member 14 formed on the front surface of the partition wall 13 forming the receiving surface of the door gasket 12 is in close contact with the door gasket 12 to prevent cold air in the freezer compartment 25 from leaking to the outside. [0004] The cold air generated by the cooler 15 provided at the back of the main body is blown into the freezer compartment 25 by the fan 16 from the outlet 17 on the back side of the freezer compartment 25 to cool the food stored in the freezer compartment 25 . [0005] And the cool air that has cooled food, as sh...
