Abstract

Provided is a refrigerator, which includes a refrigerating compartment, a freezing compartment, and a door assembly. The freezing compartment is adjacent to the refrigerating compartment. The door assembly selectively opens the refrigerating compartment and the freezing compartment. The door assembly includes a glass member defining a frontal exterior thereof and allowing an inside of the refrigerating compartment or the freezing compartment to be seen therethrough when the door assembly is closed, a deposition treated layer formed on a rear surface of the glass member to allow light to partially pass through the glass member, and a transparent plate spaced a predetermined distance from the glass member. Gas for insulation is injected in a space formed between the glass member and the transparent plate, and the space is sealed.

First claim

The invention claimed is:

1. A refrigerator, comprising:
a cabinet defining a storage chamber of which a front surface is open;
a first receiving part disposed inside the storage chamber;
a sub door, comprising:
a frame coupled to a front portion of the cabinet;
at least one second receiving part comprising a receiving basket; and
an access opening formed in the frame;

a light emitting unit disposed in the frame of the sub door;
a main door which selectively opens or closes the access opening, the main door comprising:
an inner door part which is transparent;
an outer door part which is transparent and defines a front surface of the main door, the outer door part comprising:
a transparent plate;
a reflective lamination layer formed on a front surface of the transparent plate and configured to allow at least a portion of light emitted from the light emitting unit to be transmitted to an outside of the storage chamber;
a screening layer defined at an edge portion of a rear surface of the transparent plate; and
a viewing window defined in the transparent plate, an edge of the viewing window being defined by an inner edge of the screening layer; and

a door body of which a front surface contacts the screening layer of the outer door part and a rear surface contacts the inner door part to define a space inside the main door,

wherein a size of the outer door part is larger than a size of the inner door part.

2. The refrigerator of claim 1 , further comprising:
a first handle projecting from a front surface of the frame and having a grasping groove which is recessed therein; and
a second handle defined at an edge of the main door and disposed in front of the first handle.

3. The refrigerator of claim 2 , wherein the second handle is defined at a lower edge of the main door.

4. The refrigerator of claim 1 , wherein the access opening comprises:
a first access opening; and
a second access opening defined below the first access opening,
wherein the access opening is partitioned by the first handle to define the first access opening and the second access opening.

5. The refrigerator of claim 4 , wherein the main door comprises:
a first door configured to selectively open or close the first access opening; and
a second door configured to selectively open or close the second access opening.

6. The refrigerator of claim 5 , wherein the second handle is defined at the first door.

7. The refrigerator of claim 1 ,
wherein the second receiving part comprises at least one basket.

8. The refrigerator of claim 7 ,
wherein the light emitting unit is disposed in an inner surface of a front border of the frame and is configured to emit light towards the second receiving part.

9. The refrigerator of claim 2 , further comprising an additional light emitting unit disposed in the grasping groove of the first handle and configured to illuminate the first handle in a dark indoor space.

10. The refrigerator of claim 1 , further comprising:
a first hinge configured to couple the sub door rotatably to the cabinet; and
a second hinge configured to couple the main door rotatably to the cabinet or to the sub door.
