Abstract

A refrigerator includes a cabinet provided with a storage compartment, a door capable of opening and closing the storage compartment, a turning plate and a hinge assembly including a hinge moving member and a hinge fixed member connecting the door to the turning plate. One of the hinge moving member or the hinge fixed member defines a trajectory having a first end portion and a second end portion. The other of the hinge moving member or the hinge fixed member has a limiting portion adapted to rotate between the first end portion and the second end portion along the trajectory.

First claim

The invention claimed is:

1. A refrigerator, comprising:
a cabinet having a storage compartment;
a door capable of opening and closing said storage compartment;
a turning plate; and
a hinge assembly including a hinge moving member and a hinge fixed member connecting said door to said turning plate,
one of said hinge moving member or said hinge fixed member defining a trajectory including a first end portion and a second end portion, and another of said hinge moving member or said hinge fixed member having a limiting portion adapted to rotate between said first end portion and said second end portion along said trajectory;
one of said hinge moving member or said hinge fixed member having a receiving groove in communication with said trajectory, said other of said hinge moving member or said hinge fixed member including a body portion being internally hollow and being accommodated in said receiving groove, said limiting portion being formed in one piece with said body portion and said limiting portion protruding into said trajectory from said body portion.

2. The refrigerator according to claim 1 , wherein said receiving groove includes a receiving space having a fan-shaped cross section, and said trajectory includes a limiting space having a ring-shaped cross section.

3. The refrigerator according to claim 2 , wherein said first end portion and said second end portion are respectively in communication with said receiving space.

4. The refrigerator according to claim 2 , wherein an outer ring diameter of said ring-shaped cross section of said limiting space is greater than a diameter of said fan-shaped cross section of said receiving space.

5. The refrigerator according to claim 1 , wherein said body portion is cylindrical, and said limiting portion is a rib on said body portion.

6. The refrigerator according to claim 1 , wherein one of said hinge moving member or said hinge fixed member has a first butting portion provided with said trajectory and said receiving groove, and said other of said hinge moving member or hinge fixed member has a second butting portion abutted against said first butting portion.

7. The refrigerator according to claim 6 , wherein said body portion and said limiting portion extend from said second butting portion to said first butting portion.

8. The refrigerator according to claim 6 , wherein said first butting portion includes a first butting surface, and said second butting portion includes a second butting surface abutted against said first butting surface.

9. The refrigerator according to claim 8 , wherein said first butting surface and said second butting surface are mutually fitting curved surfaces.

10. The refrigerator according to claim 6 , wherein said body portion and said limiting portion are smaller in size than said second butting portion.

11. The refrigerator according to claim 1 , wherein said hinge fixed member encompasses said trajectory, and said hinge moving member includes said limiting portion.
