no. 1 approach

[0046] Embodiments of the present invention will be described below with reference to the drawings. figure 1 The front view which shows the refrigerator of 1st Embodiment. Refrigerator 1 is equipped with main body part 2, and described main body part 2 is filled with foam insulation material 20 such as polyurethane foam between inner case 2a and outer case 2b (both refer to Figure 5 ) made of heat-insulated box.

[0047] Refrigerator compartment 3 is arranged on the upper part of main body part 2 , and ice maker compartment 5 and freezer compartment 6 are arranged side by side under refrigerator compartment 3 . Freezer compartment 7 is arranged below ice making compartment 5 and freezer compartment 6 , and vegetable compartment 8 is arranged under freezer compartment 7 . The ice making compartment 5 , the freezing compartment 6 and the freezing compartment 7 form respectively communicating freezing spaces at the rear of the main body 2 .

[0048] The front of the refriger...

no. 2 approach

[0112] Next, Figure 17 The top view which shows the door 13 and the door 14 of the refrigerator 1 of 2nd Embodiment. in addition, Figure 18 , Figure 19 A side sectional view and a planar sectional view of the freezer compartment 7 are shown. This embodiment is relative to the Figure 1 to Figure 16 In the first embodiment shown, the arrangement of the passage forming portion 40 is different. Other parts are the same as the first embodiment.

[0113] A weather strip 23 that contacts the front of the peripheral wall of the refrigerator compartment 3 when closed is provided on the periphery of the back surface of the door 13 of the refrigerator compartment 3 . The protruding portion 13c of the door 13 and the inner surface of the peripheral wall of the refrigerator compartment 3 are provided with a narrow passage 41 (refer to Figure 16 ) of a pair of passage forming portions 40.

[0114] Similarly, a weather strip 24 (refer to figure 2 ), the sealing strip 24 contact...

no. 3 approach

[0120] Next, Figure 20 The rear view which shows the narrow passage 31 of the refrigerator 1 which concerns on 3rd Embodiment. This embodiment is for the Figure 1 to Figure 16 In the first embodiment shown, the shape of the narrow passage 31 is different. Other parts are the same as the first embodiment.

[0121] One side wall 31b of the narrow passage 31 between the doors 13, 14 is formed as a flat surface by the gasket 14b. The other side wall 31a of the narrow passage 31 is formed by the gasket 13b, and a plurality of grooves 35 and flat tops 37 arranged in the Z direction are formed on the side wall 31a. Thereby, since the pressure loss of the narrow passage 31 becomes large, the cold air which reaches the weather strip 21 and the weather strip 22 from the inner side of a refrigerator can be reduced. Thus, the heater 52 is reduced (refer to Figure 4 ), the power consumption of the refrigerator 1 can be saved.

[0122] According to this embodiment, the same effect ...

Abstract

The present invention provides a refrigerator (1) in which the front surface of a storage compartment (3) is opened and closed by doors (13, 14), and the storage compartment 3 is sealed by packing (21, 22) when the doors (13, 14) are closed. The refrigerator (1) is provided with a narrow passage (31) which is slit-shaped, extends in the longitudinal direction of the packing (21, 22), is formed closer to the inner side of the refrigerator than the packing (21, 22) when the doors (13, 14) are closed, and forms a cool air flow passage extending in a direction perpendicular to the longitudinal direction of the packing (21, 22). One and / or the other of the facing sidewalls of the narrow passage (31) has: a plurality of grooves (35) which are either arranged side by side in the longitudinal direction of the packing (21, 22) or extended in the longitudinal direction; and lands (37) defined by the grooves (35).

Description

technical field [0001] The invention relates to a refrigerator which uses a sealing strip to seal a storage room. Background technique [0002] In Patent Document 1, there is disclosed a conventional refrigerator in which a storage compartment is sealed with a weather strip. In this refrigerator, a storage compartment is provided in an insulating box filled with foam insulation, and the storage compartment is opened and closed by a door pivotally supported by a vertical pivot. The peripheral wall of the storage room is constituted by a heat-insulating box, and an annular weatherstrip (gasket) disposed around the door abuts against the front surface of the peripheral wall of the storage room, thereby sealing the storage room. [0003] A stepped portion is formed at the front end of the inner surface of the peripheral wall of the storage compartment. A protrusion protruding rearward is provided around the door. When the door is closed, the protruding portion enters into the...
