Abstract

Provided is a refrigerator including a main body configured to form a storage chamber, a door configured to open and close the storage chamber, a hinge configured to rotatably support the door, and a height adjusting device configured to be coupled to the hinge and located inside the door, wherein the height adjusting device includes a lever provided to be operable from an outside of the door, a power transmission member provided to be movable as the lever rotates, and a support member configured to guide the power transmission member in a first direction as the lever rotates to move the power transmission member so that a height of the door is increased, and guide the power transmission member in a second direction, different from the first direction, as the lever rotates to move the power transmission member so that the height of the door is decreased.

Claims (59)

1. A refrigerator comprising:

a main body configured to form a storage chamber;

a door configured to open and close the storage chamber;

a hinge configured to rotatably support the door; and

a height adjusting device configured to be coupled to the hinge and located inside the door,

wherein the height adjusting device includes:

a lever that is operable from an outside of the door,

a power transmission member that is movable as the lever rotates,

a support member supported by the hinge, and configured to guide the power transmission member to move in a first approximately vertical direction as the lever rotates to move the power transmission member in a first approximately horizontal direction so that a height of the door is increased, and guide the power transmission member to move in a second approximately vertical direction as the lever rotates to move the power transmission member in a second approximately horizontal direction so that the height of the door is decreased, and

a case fixed to the door, in which the power transmission member is movably accommodated, and configured to allow movement of the power transmission member relative to the case in the first approximately horizontal direction or the second approximately horizontal direction while restricting movement of the power transmission member relative to the case in the first approximately vertical direction and the second approximately vertical direction.

2. The refrigerator of claim 1 , wherein the lever is rotatable and configured to move the power transmission member linearly in the first approximately horizontal direction and the second approximately horizontal direction according to a direction of rotation of the lever.

3. The refrigerator of claim 1 , wherein the support member is configured to guide the power transmission member to perform relative movement with respect to the door to thereby adjust the height of the door.

4. The refrigerator of claim 1 , wherein the support member includes a support inclined portion configured to support the power transmission member such that the height of the door is adjusted in response to the power transmission member being moved in the first approximately horizontal direction and the second approximately horizontal direction.

5. The refrigerator of claim 1 , wherein the power transmission member includes a conversion inclined portion supported by the support member such that the height of the door is adjusted in response to the power transmission member being moved in the first approximately horizontal direction and the second approximately horizontal direction.

6. The refrigerator of claim 1 , wherein

the first approximately horizontal direction is set as a direction in which the power transmission member moves toward the support member, and

the second approximately horizontal direction is set as a direction in which the power transmission member moves away from the support member.

7. The refrigerator of claim 1 , wherein the case includes a lever opening formed to allow at least a portion of the lever to be exposed to the outside of the door.

8. The refrigerator of claim 1 , wherein

the door is an upper door and the refrigerator includes a lower door, and

the height adjusting device is located on one end of the upper door adjacent to the lower door.

9. The refrigerator of claim 1 , further comprising:

a bolt provided to rotate as the lever rotates; and

a nut couplable to the bolt, and while coupled to the bolt configured to be movable together with the power transmission member.

10. The refrigerator of claim 9 , wherein the nut is fixed so as to be restricted from performing relative rotation with respect to the power transmission member.

11. The refrigerator of claim 1 , wherein the lever is provided to be manipulated from the outside of the door while the storage chamber is closed by the door.

12. The refrigerator of claim 1 , wherein the lever includes a screw thread spirally extended with the first approximately horizontal direction or the second approximately horizontal direction as an axis, and

the power transmission member includes a rack formed to be engaged with the screw thread.

13. The refrigerator of claim 1 , wherein the lever includes a manipulation portion and a pinion at a side opposite to the manipulation portion, and

the power transmission member includes a rack formed to be engaged with the pinion.

14. A refrigerator comprising:

a main body configured to form a storage chamber;

a door configured to open and close the storage chamber;

a hinge configured to rotatably support the door; and

a height adjusting device configured to be coupled to the hinge and provided on the door,

wherein the height adjusting device includes:

a lever having at least a portion thereof exposed to an outside of the door, the lever being rotatable from the outside of the door,

a bolt fixed to the lever, and provided to rotate together with the lever,

a nut coupled to the bolt,

a power transmission member, to which the nut is fixed, and that is movable as the lever rotates,

a support member supported by the hinge, and configured to support the power transmission member such that a height of the door is adjusted in response to the power transmission member being moved by the lever toward and away from the support member, and

a case fixed to the door, in which the power transmission member is movably accommodated, and formed to allow relative movement of the power transmission member in a first direction and a second direction while restricting relative movement of the power transmission member in a height direction of the door.

15. The refrigerator of claim 14 , wherein

the support member includes a support inclined portion configured to support the power transmission member in a direction to change the height of the door when the power transmission member is moved by the lever, and

the power transmission member includes a conversion inclined portion provided to correspond to the support inclined portion.

16. The refrigerator of claim 14 , wherein the power transmission member is configured to perform move relative movement with respect to the door.

17. The refrigerator of claim 14 , wherein

the door is an upper door and the refrigerator includes a lower door, and

the height adjusting device is located at one end of the upper door adjacent to the lower door.

18. A refrigerator comprising:

a main body configured to form a storage chamber;

a door configured to open and close the storage chamber;

a hinge configured to rotatably support the door; and

a height adjusting device mountable on the door,

wherein the height adjusting device includes:

a lever having a manipulation portion that is exposed to an outside of the door, the lever being rotatable from the outside of the door,

a power transmission member configured to be movable as the lever rotates,

a support member supported by the hinge, and including a support inclined portion formed to move the power transmission member along a height direction of the door when the power transmission member is moved by the lever toward and away from the support member, and

a case fixed to the door, in which the power transmission member is movably accommodated, and formed to allow relative movement of the power transmission member in a first direction and a second direction while restricting relative movement of the power transmission member in a height direction of the door.
