Abstract

Provided is a refrigerator having only a second door opened/closed or having both of a first door and a second door opened/closed using one handing by allowing a latch device to fix the second door to the first door or release the second door from being fixed to the first door. The refrigerator includes a main body having a storage compartment, a first door that is rotatably disposed in front of the main body and has an opening formed therein, a second door that is rotatably disposed in front of the first door to open/close the opening, a handle coupled to a front side of the second door to open/close the first door and the second door, and a latch device allowing the second door to be fixed and released to/from the first door.

Claims (37)

1. A refrigerator comprising:

a main body having a storage compartment;

a first door for the storage compartment disposed at a front side of the main body and having an opening formed therein;

a second door disposed at a front side of the first door to open or close the opening of the first door;

a handle disposed at the second door to open or close the first door and the second door together or to open or close the second door alone; and

a latch device configured to allow the second door to open or close together with the first door or to open or close alone, wherein the latch device comprises:

a fixing unit provided at the first door;

a support detachably coupled to the handle and disposed between the handle and the second door;

a handle lever rotatably coupled to the support by a rotation shaft and including a first portion to rotate about the rotation shaft forward or backward and a second portion to rotate about the rotation shaft downward or upward when the first portion is rotated forward or backward by being pressed or released; and

a guide provided at the second door for the second portion of the handle lever to extend therethrough, wherein the support of the latch device includes

an opening through which the first portion of the handle lever is to rotate forward or backward and

a guide portion through which the second portion of the handle lever extends.

2. The refrigerator of claim 1 , further comprising a spring elastically supporting the first portion of the handle lever such that the first portion of the handle lever rotates backward when the first portion of the hand level is released after being pressed.

3. The refrigerator of claim 1 , wherein the guide portion of the support of the latch device is coupled to the guide provided at the second door, and the second portion of the handle lever is selectively accommodated in the fixing unit provided at the first door through the guide.

4. The refrigerator of claim 1 , wherein the fixing unit includes a backward protrusion defining an accommodation portion for the second portion of the handle lever.

5. The refrigerator of claim 4 , wherein the fixing unit includes a hanging hook in the accommodation portion.

6. The refrigerator of claim 5 , wherein the second portion of the handle lever engages with the hanging hook when the first portion of the handle lever is released, and the second portion of the handle lever disengages with the hanging hook when the first portion of the handle lever is pressed.

7. The refrigerator of claim 1 , wherein the handle extends vertically, and the second portion of the handle lever of the latch device is located at a vertical central portion of the handle.

8. The refrigerator of claim 3 , wherein the guide portion of the support of the latch device is configured to hide the second portion of the handle lever therein.

9. The refrigerator of claim 1 , wherein

the fixing unit includes a hanging hook, and

the second portion of the handle lever includes a hanging protrusion for the hanging hook of the fixing unit.

10. The refrigerator of claim 1 , wherein the guide is provided to guide the movement of the second portion of the handle lever.

11. A refrigerator comprising:

a main body having a storage compartment;

a first door for the storage compartment disposed at a front side of the main body and having an opening formed therein;

a second door disposed at a front side of the first door to open or close the opening of the first door;

a handle disposed at the second door to open or close the first door and the second door together or to open or close the second door alone; and

a latch device configured to allow the second door to open or close together with the first door or to open or close alone, wherein the latch device comprises:

a fixing unit provided at the first door;

a support detachably coupled to the handle and disposed between the handle and the second door;

a handle lever rotatably coupled to the support by a rotation shaft and including a first portion to rotate about the rotation shaft forward or backward and a second portion to rotate about the rotation shaft downward or upward when the first portion is rotated forward or backward by being pressed or released, respectively; and

a guide provided at the second door for the second portion of the handle lever to extend therethrough.

12. The refrigerator of claim 11 , wherein the support of the latch device includes an opening through which the first portion of the handle lever is to rotate forward or backward and a guide portion through which the second portion of the handle lever extends.

13. The refrigerator of claim 11 , wherein the fixing unit includes a backward protrusion defining an accommodation portion for the second portion of the handle lever.

14. The refrigerator of claim 13 , wherein the guide portion of the support of the latch device is coupled to the guide provided at the second door, and the second portion of the handle lever is selectively accommodated in the fixing unit provided at the first door through the guide.

15. The refrigerator of claim 11 , further comprising a spring elastically supporting the first portion of the handle lever such that the first portion of the handle lever rotates backward when the first portion of the hand level is released after being pressed.
