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 therein while having one surface thereof open, a heat insulation member accommodated in the accommodating space, a cover configured to cover the one surface of the case that is open, and a metallic plate being coupled to an outer side of the cover. The cover includes a heat conduction blocking part being protruded to both sides of the metallic plate while having a bent-shape cross section so as to prevent heat from being transmitted to both side surfaces of the rotating bar after being heat conducted along the metallic plate.

First claim

What is claimed is:

1. A refrigerator, comprising:
a body;
a storage compartment having an opening;
a first door configured to open/close a portion of the opening;
a second door configured to open/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 to seal a gap formed between the first door and the second door in a state that 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 provided with an accommodating space therein;
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 contact with 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; and
sealing members 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.

2. The refrigerator of claim 1 , wherein an upper one of the sealing members is configured to cover the gap between the rotating bar and the guide part.

3. The refrigerator of claim 1 , wherein the heat generating member is a heating cable.

4. The refrigerator of claim 1 , wherein the heat generating member is disposed to be line-contacted with the metallic plate to prevent heat from excessively being transferred to the metallic plate.

5. The refrigerator of claim 1 , wherein an inside of at least one of the heat conduction blocking parts is empty to prevent heat generated at the heat generating member from moving to an inside of the storage compartment.

6. The refrigerator of claim 1 , wherein a lower one of the sealing members is configured to cover a gap between the rotating bar and the body.

7. The refrigerator of claim 1 , wherein the insertion protrusion includes a stopper part to prevent the insertion protrusion from being separated from the outside the rotating bar.

8. The refrigerator of claim 1 , wherein the case and the metallic plate are configured to form a front appearance of the rotating bar.

9. The refrigerator of claim 8 , wherein the cover further includes a heat insulation member close-contact part being in contact with the heat insulation member, a second coupling part to which the metallic plate, and a side surface forming part forming at least one portion of the side surface of the rotating bar.

10. The refrigerator of claim 9 , wherein the metallic plate comprises a gasket close-contact part coming into close contact with the first gasket and the second gasket,
the first coupling part is coupled to the cover while being bent inwardly from the gasket close-contact part, and
the heat conduction blocking part and the gasket close-contact part form a same flat surface.

11. The refrigerator of claim 8 , wherein the cover is formed of non-metallic material having a heat conductivity rate lower than a heat conductivity rate of the metallic plate.

12. A refrigerator, comprising:
a body;
a storage compartment having a opening;
a first door configured to open/close a portion of the opening;
a second door configured to open/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 to seal a gap formed between the first door and the second door in a state that 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 provided with an accommodating space therein;
a cover to cover the accommodating space, the cover 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;
a heat generating member configured to contact the metallic plate; and
an insertion protrusion with an inclined surface, the insertion protrusion being configured to be downwardly movable when the inclined surface is collided with the guide part,
wherein the cover is formed of non-metallic material having a heat conductivity rate lower than a heat conductivity rate of the metallic plate.
