The upper end of the door 30 is provided with a hole 32, and the rotating shaft 62 is inserted into the hole 32 and can rotate relative to the hole 32, so that the connecting rod 60 is rotatably connected with the door 30.

In the assembled state, part or all of the guide groove 45 is located in the circle of the sliding groove 61 rotating around the rotating shaft 62, so that the sliding groove 61 and the guide groove 45 can intersect with each other during the movement of the door 30, and the overall structure of the hinge 60 can be more compact.

The pin 70 penetrates through the sliding groove 61 and the guide groove 45; in the process of rotating the door 30, the connecting rod 60 rotates and moves along with the door 30, and the sliding groove 61 on the connecting rod 60 and the guide groove 45 on the hinge plate 41 intersect to form a penetrating space of the pin 70, so that the door 30 can stay at the opening position through the cooperation of the pin 70, the sliding groove 61 and the guide groove 45 without being affected by external force.

Fig. 5 is a perspective view of a pin shaft in a hinge of a refrigerator according to an embodiment of the present disclosure.

Referring to fig. 5, the upper and lower ends of the pin 70 have a first stopper 71 and a second stopper 72 protruded outwardly along the circumference, and the guide groove 45 and the sliding groove 61 are inserted into the pin 70 and positioned between the first stopper 71 and the second stopper 72, thereby preventing the guide groove 45 and the sliding groove 61 from being separated from the pin 70.

In other embodiments, a third retaining ring 73 is further disposed in the middle of the pin 70, and the third retaining ring 73 vertically separates the guide groove 45 from the sliding groove 61, that is, the guide groove 45 is located between the first retaining ring 71 and the third retaining ring 73, and the sliding groove 61 is located between the third retaining ring 73 and the second retaining ring 72, so that the problem of locking when the door 30 rotates due to the large friction caused by the contact between the walls forming the guide groove 45 and the sliding groove 61 can be avoided.

The third stopper ring 73 may be integrally formed with the pin 70, and the first stopper ring 71 and the second stopper ring 72 are separately provided and fixed to the pin 70 by riveting.

Referring to fig. 6 and 7, when the door 30 is at the closed position, the track groove 31 is inclined rearward in the direction from the right side to the left side of the cabinet 10 (the direction toward the center of the cabinet 10), the guide groove 45 is inclined forward, and the front end of the guide groove 45 is located between the rotation shaft of the link 60 and the track groove 31 in the lateral direction.

Specifically, when the door 30 is in the closed position, the hinge shaft 44 is located at the first end 31a of the track groove 31, the pin 70 is inserted through the proximal end 61a of the sliding groove 61 and the rear end of the guide groove 45, and the link 60 and the guide groove 61 are folded.

Fig. 8 is a schematic view of a door of a refrigerator according to an embodiment of the present disclosure in a state of being opened by 30 °; FIG. 9 is an enlarged view taken along the Y-axis of FIG. 8; the hinge plate 41 is transparentized and indicated by dashed lines in the drawings for clarity.

Referring to fig. 8 and 9, which are views illustrating a state where the door is opened at 30 ℃, the track groove 31 moves to the left (in a direction approaching the center of the cabinet 10) while rotating 30 ° with respect to the hinge shaft 44, and the link 60 rotates to adaptively adjust the position of the pin 70 between the slide groove 61 and the guide groove 45. The door 30 can move to the left side by an external force (a force applied by a user or a reaction force of the cabinet 80 when the door 30 touches the cabinet 80) in the rotating process, so that the refrigerator 1 is installed and used in an embedded manner.

When the door 30 is opened at a certain position without force, the chute 61 and the guide groove 45 enclose a space for inserting the pin 70, and the door 30 can stay at the position under the cooperation of the connecting rod 60, the pin 70 and the guide groove 45.

Fig. 10 is a schematic view of a door of a refrigerator according to an embodiment of the present disclosure in a 90 ° open state; FIG. 11 is an enlarged view taken in the direction Z of FIG. 10, in which the hinge plate 41 has been made transparent for clarity and is shown in phantom

Referring to fig. 10 and 11, which are diagrams illustrating a state of the door body when the door body is opened at 90 ℃, the door body 30 continues to rotate and open, the track groove 31 rotates relative to the hinge shaft 44, the connecting rod 60 rotates and the guide groove 45 expands to adaptively adjust the position of the pin shaft 70 between the sliding groove 61 and the guide groove 45, and the door body 30 does not exceed or excessively exceeds the side surface of the box body 10 within the range of 90 degrees when being opened.

When the door 30 is in the closed position (fig. 7), the track groove 31 is inclined backward from right to left (in a direction close to the center of the cabinet 10), the hinge shaft 44 is located at the first end 31a of the track groove 31, and during the opening of the door 30 (fig. 9), the second end 31b of the track groove 31 gradually rotates to the right side of the hinge shaft 44, so that the track groove 31 can move to the left side with respect to the hinge shaft 44.

The hinge 40 of the present disclosure only realizes the purpose that the door 30 can move towards the central direction of the box 10 through the sliding groove 61 and the connecting rod 60, and has a simpler structure and a low cost.

The track groove 31 may be arc-shaped to make the movement of the door 30 more smooth during the opening and closing process, and in other embodiments, the track groove 31 may also be linear.

Providing the guide groove 45 to be inclined forward and the front end of the guide groove 45 in the lateral direction between the rotation axis of the link 60 and the locus groove 31 makes it possible to make the structure of the entire hinge 40 compact.

When the door 30 is rotated to open the storage compartment 20, a user can apply a force to the door 30 in a direction close to the center of the refrigerator body 10, or when a corner of the door 30 touches the cabinet 80, the door 80 is pushed, so that the track groove 31 moves in the direction of the center of the refrigerator while rotating relative to the hinge shaft 44, thereby avoiding the problem that the door 30 exceeds or excessively exceeds the side surface of the refrigerator body 10 in the rotating process, which results in the refrigerator 1 being unable to be used in an embedded manner.

In some embodiments, the rotation axis of the connecting rod 60 is closer to the center of the refrigerator than the track groove 31, so that the hinge shaft 44 is as close to the side of the refrigerator body 10 as possible, and the corner of the door 30 is less likely to touch the refrigerator body 10.

In some embodiments, the length of the position of the guide groove 45 and the slide groove 61 may be set according to the following manner: the pin 70 is located at the proximal end 61a of the chute 61 and the rear end of the guide groove 45 when the door body 30 is in the closed position; the pin 70 is located at the distal end 61b of the sliding chute 61 and the front end of the guide groove 45 when the door body 30 is at the 90 ° open position. In other embodiments, the sliding groove 61 and the guiding groove 45 can be lengthened based on the above setting manner, so that the pin 70 is located between the guiding groove 45 and the sliding groove 61 during the whole movement of the door 30.

In some embodiments, with continued reference to fig. 3, an end cap 33 is attached to the upper end of the door 30, and the track groove 31 and the hole 32 are disposed on the end cap 33, so as to facilitate the processing of the track groove 31 and the hole 32.

The end cap 33 is made of a POM material having lubricity, so that the door 30 can move more smoothly with respect to the cabinet 10.
