Abstract

A refrigerator includes a rotating bar configured to seal a gap between one pair of doors. The rotating bar includes a case provided with an accommodating space; a cover to cover the accommodating space, and having heat conduction blocking parts at both sides thereof; a heat insulation member accommodated in the accommodating space; a metallic plate positioned between the heat conduction blocking parts; and a heat generating member configured to be attached to a rear surface of the metallic plate. An insertion protrusion with an inclined surface is configured to be downwardly movable when the inclined surface is collided with the guide part. Sealing members made of rubber are disposed at vertical end portions of the rotating bar, the sealing members to cover gaps formed at the vertical end portions of the rotating bar when the first door is closed.

First claim

What is claimed is:

1. A refrigerator, comprising:
a body;
a storage compartment having an opening;
a first door configured to open or close a portion of the opening;
a second door configured to open or close a remaining portion of the opening;
a first gasket installed at a rear surface of the first door;
a second gasket installed at a rear surface of the second door;
a rotating bar coupled to the first door, and configured to seal a gap formed between the first door and the second door when the first door and the second door are closed, and
a guide part provided within the storage compartment, and configured to guide rotation of the rotating bar;
wherein the rotating bar comprises:
a case having an accommodating space;
a cover covering the accommodating space, and having a recess;
a heat insulation member accommodated in the accommodating space;
a metallic plate positioned in the recess of the cover;
a heat generating member positioned in the recess between the metallic plate and the cover; and
a first sealing member formed of a material that is more flexible than the case disposed at a longitudinal end portion of the rotating bar, the first sealing member configured to cover a gap formed between the body and the longitudinal end portion of the rotating bar when the first door is closed.

2. The refrigerator of claim 1 , wherein the rotating bar further includes a second sealing member disposed at another longitudinal end portion of the rotating bar, and the second sealing member is configured to cover a gap formed between the body and the other longitudinal end portion of the rotating bar when the first door is closed.

3. The refrigerator of claim 2 , wherein the second sealing member is formed of the material that is more flexible than the case.

4. The refrigerator of claim 1 , wherein the first sealing member includes a blocking wall configured to seal the gap formed between the body and the longitudinal end portion of the rotating bar when the first door is closed.

5. The refrigerator of claim 2 , wherein the second sealing member includes a blocking wall configured to seal the gap formed between the body and the other longitudinal end portion of the rotating bar when the first door is closed.

6. The refrigerator of claim 1 , wherein the rotating bar further comprises an insertion protrusion with an inclined surface that facilitates a downward movement of the rotating bar when the inclined surface collides with the guide part.

7. The refrigerator of claim 1 , wherein the cover is formed of non-metallic material having a heat conductivity rate lower than a heat conductivity rate of the metallic plate.

8. The refrigerator of claim 1 , wherein the heat generating member is in contact with the metallic plate.

9. A refrigerator, comprising:
a body;
a storage compartment having an opening;
a first door configured to open or close a portion of the opening;
a second door configured to open or close a remaining portion of the opening;
a first gasket installed at a rear surface of the first door;
a second gasket installed at a rear surface of the second door;
a rotating bar coupled to the first door, and configured to seal a gap formed between the first door and the second door when the first door and the second door are closed; and
a guide part provided within the storage compartment, and configured to guide rotation of the rotating bar;
wherein the rotating bar comprises:
a case having an accommodating space;
a cover covering the accommodating space;
a heat insulation member accommodated in the accommodating space;
a metallic plate positioned at a front side of the cover;
a heat generating member provided at a rear side of the metallic plate; and
a sealing member formed of a material that is more flexible than the case disposed at a longitudinal end portion of the rotating bar, to cover a gap formed between the guide part and the longitudinal end portion of the rotating bar when the first door is closed.
