Abstract
The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body. A guide block is provided on the door, a rotation shaft is provided on the hinge body, and rotation shaft grooves are provided on the guide block. With the structure of the hinge body, the gravity of the door and the friction force may be shared onto the first and second plate bodies of the hinge body, thereby reducing abrasion and prolonging the service life of the door of the refrigerator.
Claims17
A refrigerator, comprising a cabinet and a door for opening and closing the cabinet, wherein the refrigerator further comprises a hinge body fixedly provided on the cabinet, and a guide block fixedly provided on the door, wherein a positioning shaft and a guiding shaft are provided on the hinge body, and a positioning groove fitting with the positioning shaft and a guiding groove fitting with the guiding shaft are provided on the guiding block;
- one of left and right sides of the refrigerator which is provided with the hinge body is a pivoting side, the door is in a first state when being closed, the door has a side wall close to the pivoting side in the first state and a front wall away from the cabinet in the first state, the positioning groove has a first position close to the side wall and the front wall and a second position away from the side wall and the front wall compared with the first position, the guiding groove has a third position and a fourth position, and when the door is in the first state, the positioning shaft is located at the second position, and the guiding shaft is located at the fourth position;
- the guiding shaft and the guiding groove are provided such that when the door is opened from the first state, the door is rotated with the positioning shaft as a center of rotation, the positioning shaft is moved from the second position to the first position and the guiding shaft is moved from the fourth position to the third position with limitation of the guiding shaft and the guiding groove, at this point, the door is opened at a certain angle to be in a second state, and the door is moved by a distance towards a side away from the pivoting side;
- the refrigerator further comprises a limiting boss provided between the guide block and the hinge body to space apart the guide block from the hinge body, and the limiting boss has a front end close to the front wall and a rear end away from the front wall, so that when the door is opened, the limiting boss abuts against the hinge body all the time.
A refrigerator, comprising a cabinet and a door for opening and closing the cabinet, wherein the refrigerator further comprises a hinge assembly connecting the cabinet and the door, and the cabinet comprises an accommodation compartment and a pivoting side connected with the hinge assembly;
- during a process of opening the door, the hinge assembly drives the door to move from the pivoting side toward the accommodation compartment;
- wherein the hinge assembly comprises a positioning shaft and a positioning groove engaged with each other as well as a guiding shaft and a guiding groove engaged with each other, wherein the positioning shaft is located at one of the cabinet and the door, the positioning groove is located at the other of the cabinet and the door, the guiding shaft is located at one of the cabinet and the door, and the guiding groove is located at the other of the cabinet and the door;
- when the door is opened to the second state from the closed state, the guiding shaft is moved in the guiding groove to drive the positioning shaft to move in the positioning groove, thereby driving the door to move from the pivoting side toward the accommodation compartment;
- wherein the door comprises a front wall apart from the accommodation compartment and a side wall always sandwiched between the front wall and the accommodation compartment, the positioning groove comprises a first position, a second position, and a fifth position from a portion close to the side wall to a portion apart from the side wall, the guiding groove comprises a fourth position, a third position, a sixth position and a rotation termination position from a portion apart from the side wall to a portion close to the side wall;
- when the door is in the closed state, the guiding shaft is located at the fourth position, and the positioning shaft is located at the second position;
- when the door is opened to the second state from the closed state, the guiding shaft is moved from the fourth position to the third position to drive the positioning shaft to move from the second position to the first position;
- when the door is opened to the third state from the second state, the guiding shaft is moved from the third position to the sixth position to drive the positioning shaft to move from the first position to the fifth position;
- when the door is opened continuously from the third state, the guiding shaft is moved from the sixth position to the rotation termination position, the positioning shaft is kept at the fifth position, and an arch shape is present between the sixth position and the rotation termination position.
