It should be noted that, when the front wall surface 212 of the case door and the side wall surface 213 of the case door are both planar, the intersection line of the two planar surfaces is the theoretical first side edge 214, and when the case door is specifically machined, a curved surface is formed at this time based on the transition between the intersection of the front wall surface 212 of the case door and the side wall surface 213 of the case door, and a vertical line extending along the length direction of the case door 20 and located in the middle of the curved surface may represent the first side edge 214.

It should be noted that, in the related art, when the door rotates, the corner (or the first side edge) of the door will exceed the excessive distance of the side wall of the box, and at this time, if the box is close to the side wall of the wall or the cabinet, the corner of the door will touch the wall or the cabinet at the side of the refrigerator, so as to directly affect the use of the user.

Referring to fig. 4 to 6, fig. 4 is a schematic structural view of the shaft sleeve shown in fig. 2, fig. 5 is an assembled view of the shaft sleeve and the hinge shown in fig. 2, and fig. 6 is a schematic structural view of the hinge of the refrigerator shown in fig. 1. The hinge 30 has a first shaft body 31 and a second shaft body 32, and the first shaft body 31 is located between the cabinet 10 and the second shaft body 32 of the refrigerator. Specifically, the first shaft body 31 is closer to the opening end face 11 of the refrigerator than the second shaft body 32. The door 20 includes a door body 21 and a bushing 24. The sleeve 24 is provided with a first runner 22 cooperating with the first shaft body 31 and a second runner 23 cooperating with the second shaft body 32. It can be appreciated that the first shaft body 31 is inserted into the first chute 22, and the second shaft body 32 is inserted into the second chute 23.

In the process of rotating the door 20 from the closed state to the first preset angle a, the door 20 can rotate with the second shaft 32 as a rotation axis, and the first shaft 31 can slide relative to the first chute 22. In the process of opening the door 20 from the first preset angle a to the second preset angle b, the door 20 can rotate with the first shaft 31 as a rotation axis, and the second shaft 32 can slide relative to the second chute 23.

The door body 21 is a main body of the door 20, and a door rear wall 211, a door front wall 212, a door side wall 213, and a first side edge 214 of the door 20 are formed on the door body 21.

It will be appreciated that the first predetermined angle a is greater than the second predetermined angle b. Through the cooperation of the first shaft body 31 and the first sliding groove 22 and the cooperation of the second shaft body 32 and the second sliding groove 23, after the fixed shaft of the door 20 rotates to a certain angle, the other shaft can be replaced to perform fixed shaft rotation motion, namely, the door 20 performs two sections of reducing motions in the rotation process, and as the first shaft body 31 is positioned between the box body 10 and the second shaft body 32, in the process that the door body 21 rotates from a closed state to a second preset angle b, the rotation radius of the corner part of the door body 21 when the second shaft body 32 is used as an axis is smaller than the rotation radius of the corner part of the door body 21 when the first shaft body 31 is used as an axis, so that the rotation center of the door 20 starts to be adjusted when the corner part of the door exceeds the side wall surface of the box body 10 by a small distance (at this moment, the door 20 rotates by using the first shaft body 31 as the rotation axis), so that the impact force is transmitted to the position of the shaft sleeve 24 and the hinge 30 after the door 20 collides with the box body or the wall body can be avoided, the corner part of the door body is prevented from being transmitted to the position of the shaft sleeve 24 and the hinge 30, the corner part is damaged, and the daily maintenance cost of the refrigerator is reduced in the use process is reduced. Further, since the shaft sleeve 24 is detachably connected with the door body 21, the whole door 20 does not need to be directly replaced even if the first sliding groove 22 and the second sliding groove 23 of the door 20 are damaged, and only the corresponding shaft sleeve 24 needs to be replaced.

Next, the structure of the boss 24 of the embodiment of the present application will be explained and explained by way of example.

The sleeve 24 may include a slot end face 241, a third sidewall 242, and a fool-proof portion 243. The notch end face 241 is formed with the notch of the first slide groove 22 and the notch of the second slide groove 23. The third side wall 242 is disposed around the slot end face 241. The fool-proof portion 243 is disposed on the third sidewall 242. Correspondingly, the door body 21 is provided with a fool-proof groove 215 which is engaged with the fool-proof part 243.

The shape of the fool-proof portion 243 may be various, such as the fool-proof portion 243 may include two first ribs protruding from the third side wall 242. The two first ribs are arranged along the axial line direction of the sleeve 24, and the two first ribs are asymmetrically arranged with respect to the axial line of the sleeve 24. Then, the error in the angle of installation of the boss 24 during the process of installing the boss 24 into the door body 21 can be avoided.

The sleeve 24 may also include a first bottom wall 244. The first bottom wall 244 is disposed opposite the slot end face 241. The third side wall 242 is circumferentially connected between the first bottom wall 244 and the slot end face 241. The first bottom wall 244 is provided with a protruding portion 245, and the door body 21 is provided with a clamping groove matched with the protruding portion 245.

The shape of the boss 245 may be varied. For example, the boss may include two second ribs arranged crisscross such that the two second ribs form a cross. Wherein, one end of each second convex rib can be connected with one end of one first convex rib.

In some embodiments, the third sidewall 242 is inclined toward the axis of the sleeve 24 in the direction of the slot end face 241 toward the first bottom wall 244. The door body 21 is provided with a first mounting groove 217. The first mounting slot 217 is an interference fit with the third sidewall 242.

Further, the boss 24 may be inserted into the first mounting groove 217 from a notch of the first mounting groove 217. During insertion of the sleeve 24 into the first mounting slot 217, an inner wall of the first mounting slot 217 may cooperate with the third sidewall 242 to allow the sleeve 24 to be automatically centered and the sleeve 24 may be secured in the first mounting slot 217 by wedging of the third sidewall 242.

Of course, in some other embodiments, the sleeve 24 may be fixed to the door 21 by screws. However, it will be further understood that if the shaft sleeve 24 is fixed by screwing, it means that a screw hole site must be reserved at a specific position of the shaft sleeve 24 and a specific position of the door body 21, that is, a specific position of the shaft sleeve 24 cannot be used to form the first sliding groove 22 and the second sliding groove 23, so that each door body 21 can only replace the shaft sleeve 24 having the first sliding groove 22 and the second sliding groove 23 with a specific shape, and the type of door opening track that can be achieved by the door body 21 is less. In this embodiment, the shaft sleeve 24 and the door body 21 are in a clamping manner, and the shaft sleeve 24 does not need to reserve a specific screw hole site, so that the shaft sleeve 24 can be provided with more types of first sliding grooves 22 and second sliding grooves 23, or the door body 21 can be replaced with more shaft sleeves 24 with different types of first sliding grooves 22 and second sliding grooves 23, so that the door body 21 can rotate along more different door opening tracks.

In some embodiments, the sleeve 24 is a self-lubricating, wear-resistant material. For example, the sleeve 24 may be ductile iron, polyoxymethylene (pom), or the like. Furthermore, during the movement of the first shaft body 31 and the second shaft body 32, the abrasion of the shaft sleeve 24, the first shaft body 31 and the second shaft body 32 can be reduced, and finally, the maintenance cost of the refrigerator in daily use can be reduced by reducing the replacement frequency of the shaft sleeve 24, the first shaft body 31 and the second shaft body 32.

Alternatively, the sleeve 24 may also be provided with a self-lubricating wear-resistant coating covering at least the first runner 22 and the second runner 23.

Based on this, the distance between the slot center of the second positioning section 231 and the door front wall surface 212 is denoted as L ₁ The distance between the center of the groove of the second positioning section 231 and the door side wall surface 213 is denoted as L ₂ The distance between the door side wall 213 and the wall or cabinet wall is denoted as L ₃ It will be appreciated that the distance between the axis of the second shaft 32 and the front wall 212 of the door is denoted as L when the door 21 is in the closed state ₁ The distance between the axis of the second shaft body 32 and the door side wall surface 213 is L ₂ Wherein, the method comprises the steps of, wherein,

in this way, when the door 20 rotates around the second shaft 32, the arc track moved by the first side edge 214 will not interfere with the wall or the cabinet wall.

Illustratively, for a built-in refrigerator, the distance between the side plate of the built-in cabinet and the side wall of the refrigerator is small, typically 2 mm to 4 mm. Based on this, in order to improve the adaptability, the structure of the door 20 of the existing refrigerator is not greatly changed, and the distance L between the center of the groove of the second positioning section 231 and the front wall surface 212 of the door can be set ₁ A distance L between the center of the groove of the second positioning section 231 and the door sidewall surface 213 of the door is set between 8.5 mm and 10.5 mm ₂ Between 14 mm and 17 mm. In other words, when the door 21 is in the closed state, the distance L between the axis of the second shaft 32 and the front wall 212 of the door ₁ Is arranged between 8.5 mm and 10.5 mm, and the distance L between the axle center of the second axle body 32 and the side wall surface 213 of the box door ₂ Between 14 mm and 17 mm. In this way, without excessively modifying the structure of the door 20 of the existing refrigerator, such as without modifying the thickness of the door 20, it is ensured that the arcuate path of movement of the first side edge 214 does not match the wall when the door 20 rotates about the second axis 32Or interference with the cabinet wall.

For example, the distance L between the center of the slot of the second positioning section 231 and the door front wall 212 can be set ₁ Is set to 9 mm, and the distance L between the center of the groove of the second positioning section 231 and the side wall surface 213 of the door ₂ Setting to 16 mm, since a radius of 1 mm is generally machined at the first side 214 (the corner of the door 20), the size of the door 20 beyond the side wall of the cabinet 10 during rotation of the door 214 may be no more than 2 mm.

It can be appreciated that after the door 20 moves to the first preset angle a with the second shaft 32 as the rotation axis, the door 20 moves to the second preset angle b with the first shaft 31 as the rotation axis, so as to realize two-stage reducing motion of the door 20. Wherein, the center distance between the first shaft body 31 and the second shaft body 32 is set between 9.5 mm and 12.5 mm, and when the door 20 is in the closed state, the first shaft body 31 is farther from the door sidewall surface 213 than the second shaft body 32. Thus, when the door 20 is converted to move around the first shaft 31, the first shaft 31 is disposed at a position that prevents the arc track of the movement of the first side edge 214 from interfering with the wall or the cabinet wall during the rotation of the door 20. And when the door 20 moves to the second preset angle b, the door 20 does not obstruct the drawing of the drawer in the storage compartment.

The angle d between the extension line of the connecting line between the center of the first shaft body 31 and the center of the second shaft body 32 and the extension surface of the door sidewall 213 ranges from 15 degrees to 25 degrees, so that the door 20 is smoother when performing two-stage reducing motion.

For ease of understanding, the following will be illustrated in connection with the specific angle of rotation of door 20.

For example, the first preset angle a may be 45 degrees, the second preset angle b may be 90 degrees, and of course, in other embodiments, the first preset angle a may be other angles such as 30 degrees or 35 degrees, and the second preset angle b may be other angles such as 80 degrees or 85 degrees.

In this embodiment, the first preset angle a is 45 degrees, and the second preset angle b is 90 degrees. When the door 20 is opened from the closed state to the angle of 45 degrees, the second shaft body 32 rotates relatively in the second positioning section 231, the door 20 can rotate with the second shaft body 32 as the rotation axis, the first shaft body 31 slides to the first positioning section 221 relative to the first track section 222, at this time, the door 20 continues to rotate, and when the door 20 is opened from the angle of 45 degrees to the angle of 90 degrees, the first shaft body 31 rotates relatively in the first positioning section 221, at this time, the door 20 can rotate with the first shaft body 31 as the rotation axis, and the second shaft body 32 slides relative to the second track section 232.

In some embodiments, the door 20 may be opened to a second predetermined angle b (such as 90 degrees), and the refrigerator may be placed in a position where the accommodating space is large, and it is understood that when the space is large, there is no need to consider the problem that the door 20 collides with the surrounding wall surface when the door 20 is rotated to a degree greater than 90 degrees.

With continued reference to fig. 11, fig. 11 is a schematic structural view of the structure shown in fig. 7 when the door is opened to a third predetermined angle. The door 20 may be opened to a third preset angle c, which is greater than the second preset angle b, such as 120 degrees. The second chute 23 may further include a limiting section 233 in communication with the second track section 232, where the limiting section 233 is located at an end of the second track section 232 away from the second positioning section 231, and in a process that the door 20 is opened from the second preset angle b to the third preset angle c, the door 20 can rotate with the first shaft body 31 as a rotation axis, and the second shaft body 32 can slide relative to the second track section 232 until the second shaft body abuts against a groove wall of the limiting section 233. Thus, the door 20 can be limited to rotate continuously by taking the first shaft 31 as the rotating shaft by the limiting function of the limiting section 233.

It is also understood that the first runner 22, which mates with the first shaft 31, and the second runner 23, which mates with the second shaft 32, may be machined directly into the door 20. In some embodiments, the first chute 22 and the second chute 23 can be formed by first forming the first chute 22 and the second chute 23 in the chute member, and then mounting the chute member to the door 20 at a position corresponding to the hinge 30, so as to form the first chute 22 and the second chute 23 at a position corresponding to the hinge 30 of the door 20.
