Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a refrigerator according to an embodiment of the present disclosure, and fig. 2 is an exploded view of a door and a hinge of the refrigerator shown in fig. 1. The embodiment of the present application provides a refrigerator, which may include a cabinet 10, a door 20, and a hinge 30. The cabinet 10 is provided with a storage compartment such as a freezing compartment, a refrigerating compartment, or a wide temperature-changing compartment. Of course, in some alternative embodiments, the storage compartment may also be a thawing compartment or a sterilization compartment with a thawing function, which is not limited in the examples of the present application. The door 20 is used to open or close the storage compartment of the cabinet 10. Wherein door 20 may be hingedly coupled to cabinet 10 via hinge 30. Specifically, hinges 30 may be provided at upper and lower portions of the cabinet 10, and the door 20 may be smoothly rotated by the hinges at the upper portion of the cabinet 10 and the hinges at the lower portion of the cabinet 10 cooperating with the door 20.

Wherein, the front end of storing room is formed with the opening or gets and put the mouth to place food to storing indoor or by the indoor food of taking out of storing room. Correspondingly, the box body comprises an opening end surface 11 forming an opening of the storage compartment.

Referring to fig. 3, fig. 3 is a sectional view of the refrigerator shown in fig. 1. The case 10 includes first and second oppositely disposed sidewalls 12 and 13 (i.e., right and left sidewalls of the case 10). The hinge 30 is disposed on the case 10 adjacent to the first sidewall 12. Alternatively, the hinge 30 is provided on the casing 10 near the second sidewall 13. Of course, for a double door refrigerator, the hinge 30 is provided adjacent to both the first side wall 12 and the second side wall 13.

The door 20 includes a door rear wall surface 211, a door front wall surface 212, and a door side wall surface 213 adjacent to the hinge 30, it being understood that the door rear wall surface 211 faces the open end surface 11 of the cabinet 10 when the door 20 is in the closed state. The door rear wall surface 211 is disposed opposite to the door front wall surface 212, and the door side wall surface 213 is connected to the door rear wall surface 211 and the door front wall surface 212. It is understood that when the hinge 30 is located at the right side of the box 10, the right side surface of the door 20 is the door side wall surface 213; when the hinge 30 is located on the left side of the casing 10, the left side surface of the door 20 is a door side wall surface 213. The intersection of the door front wall surface 212 and the door side wall surface 213 of door 20 forms a first side edge 214, or the intersection of the door front wall surface 212 and the door side wall surface 213 forms a corner portion of door 20. It should be noted that when the door front wall 212 and the door side wall 213 are both flat surfaces, the intersection line of the two flat surfaces is the theoretical first side edge 214, and when the door front wall 212 and the door side wall 213 are processed and set specifically, based on the fact that the intersection point of the door front wall 212 and the door side wall 213 passes through a rounded corner, a curved surface is formed at this time, and a vertical line extending along the length direction of the door 20 and located in the middle of the curved surface on the curved surface can represent the first side edge 214.

It should be noted that, in the related art, when the box door rotates, the corner portion (or the first lateral edge) of the box door may exceed the side wall of the box body by an excessive distance, and at this time, if the box body is closer to the side wall of the wall or the cabinet, the corner portion of the box door may touch the wall or the cabinet on the side of the refrigerator, which directly affects the use of the user.

Based on this, please refer to fig. 4 to 6, fig. 4 is a schematic structural view of the bushing shown in fig. 2, fig. 5 is an assembly view of the bushing 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 body 10 of the refrigerator and the second shaft body 32. Specifically, the first shaft body 31 is closer to the open 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 engaged with the first shaft body 31 and a second runner 23 engaged with the second shaft body 32. It can be understood that the first shaft body 31 is inserted into the first sliding groove 22, and the second shaft body 32 is inserted into the second sliding groove 23.

Referring to fig. 7 to 10, fig. 7 is a schematic view illustrating a hinge and first and second sliding grooves of fig. 6, fig. 8 is a partially enlarged view of the hinge of the structure of fig. 7, fig. 9 is a schematic view illustrating a door of the structure of fig. 7 when the door is opened to a first predetermined angle, and fig. 10 is a schematic view illustrating the door of the structure of fig. 7 when the door is opened to a second predetermined angle. During 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 the rotation axis, and the first shaft 31 can slide relative to the first sliding chute 22. During 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 the door rear wall surface 211, the door front wall surface 212, the door side wall surface 213, and the 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 matching of the first shaft 31 and the first chute 22 and the matching of the second shaft 32 and the second chute 23, after the door 20 rotates to a certain angle in a fixed axis manner, the other shaft can be replaced to perform fixed axis rotation movement, that is, the door 20 performs two sections of variable diameter movement in the rotation process, and because the first shaft 31 is located between the box body 10 and the second shaft 32, in the process that the door body 21 rotates from the closed state to the second preset angle b, the rotation radius of the corner portion of the door body 21 rotating around the second shaft 32 is smaller than the rotation radius of the corner portion of the door body 21 rotating around the first shaft 31, so that the rotation center of the door 20 starts to be adjusted when the corner portion of the door 20 exceeds the side wall surface of the box body 10 by a small distance (at this time, the door 20 rotates around the first shaft 31 as a rotation axis), so as to avoid the cabinet or the wall on the side of the refrigerator, and further avoid that the impact force is transmitted to the shaft sleeve 24 and the hinge 30 after the door 20 collides with the cabinet or the wall and causes damage to the shaft sleeve 24 and the hinge 30, thereby reducing the number of damage in the daily use and reducing the maintenance cost of the refrigerator. Furthermore, since the shaft sleeves 24 are detachably connected to the door body 21, even if the first sliding slot 22 and the second sliding slot 23 of the door 20 are damaged, the whole door 20 does not need to be directly replaced, and only the corresponding shaft sleeve 24 needs to be replaced.

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

The sleeve 24 may include a notch end surface 241, a third side wall 242, and a fool-proof portion 243. The notch end surface 241 is formed with the notches of the first slide groove 22 and the notches of the second slide groove 23. The third side wall 242 is disposed around the notch end surface 241. The fool-proof portion 243 is disposed on the third sidewall 242. Accordingly, the door body 21 is provided with the fool-proof groove 215 engaged with the fool-proof portion 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 center line direction of the boss 24, and the two first ribs are disposed asymmetrically with respect to the axial center line of the boss 24. It is possible to prevent the sleeve 24 from being mounted at an incorrect angle during the process of mounting the sleeve 24 into the door body 21.

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

The shape of the projection 245 may be varied. For example, the projection may include two second ribs arranged criss-cross such that the two second ribs form a cross shape. Wherein one end of each second rib may be connected to one end of one first rib.

In some embodiments, the third side wall 242 is inclined toward the axial center line of the sleeve 24 along the direction in which the notch end surface 241 faces the first bottom wall 244. The door body 21 is provided with a first mounting groove 217. The first mounting groove 217 is interference fit with the third sidewall 242.

Further, the boss 24 may be inserted into the first mounting groove 217 from the notch of the first mounting groove 217. During insertion of the bushing 24 into the first mounting groove 217, the inner wall of the first mounting groove 217 may cooperate with the third side wall 242 to cause the bushing 24 to automatically center and center, and the bushing 24 may be wedge-fixed within the first mounting groove 217 by the third side wall 242.

Of course, in some other embodiments, the bushing 24 may be fixed to the door 21 by screws. However, it can be understood that if the shaft sleeve 24 is fixed by screwing, it means that screw hole positions must be reserved at specific positions of the shaft sleeve 24 and specific positions of the door body 21, that is, it is limited that specific positions of the shaft sleeve 24 cannot be used for forming the first sliding chute 22 and the second sliding chute 23, so that each door body 21 can only replace the shaft sleeve 24 with the first sliding chute 22 and the second sliding chute 23 having specific shapes, and the door body 21 can realize fewer types of door opening tracks. In the embodiment of the present application, the shaft sleeve 24 and the door body 21 are engaged, and specific screw hole positions do not need to be reserved in the shaft sleeve 24, so that more types of first sliding grooves 22 and second sliding grooves 23 can be arranged in the shaft sleeve 24, or more shaft sleeves 24 with different types of first sliding grooves 22 and second sliding grooves 23 can be replaced in the door body 21, so that the door body 21 can rotate along more different door opening tracks.

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

While the above is some examples of the bushing 24 according to the embodiment of the present application, other structures of the refrigerator will be described as follows.

It is understood that the upper and lower ends of the refrigerator are provided with hinges 30, and the upper and lower ends of the door 20 are provided with first and second sliding

grooves

22 and 23 corresponding to the positions of the hinges 30. And the first sliding grooves 22 at the upper and lower ends of the door 20 correspond to each other in vertical position, and the second sliding grooves 23 at the upper and lower ends of the door 20 correspond to each other in vertical position, so that the movement of the upper and lower ends of the door 20 is kept consistent, and the door 20 is opened or closed more smoothly.

It will also be understood that the hinge 30 comprises a connecting plate 33, the connecting plate 33 being fixed to the cabinet 10 of the refrigerator, such as the connecting plate 33 being fixed to the cabinet 10 of the refrigerator by means of a screw connection. The first shaft body 31 and the second shaft body 32 are provided to the connecting plate 33. The first shaft 31 and the second shaft 32 are integrally formed with the connecting plate 33. The first shaft 31 and the second shaft 32 may be formed as a separate body from the connecting plate 33 and then assembled to the connecting plate 33.

Illustratively, in order to allow the first shaft body 31 and the second shaft body 32 to rotate or slide more smoothly in the corresponding sliding grooves, at least one of the first shaft body 31 and the second shaft body 32 is rotatably connected to the connecting plate 33.

In order to more clearly illustrate the matching connection relationship between the first shaft 31 and the first sliding chute 22, and the matching connection relationship between the second shaft 32 and the second sliding chute 23, the detailed structure of the first shaft 31, the first sliding chute 22, the second shaft 32 and the second sliding chute 23 will be described in detail below with reference to the drawings.

The first sliding chute 22 is communicated with the second sliding chute 23, the depth of the first sliding chute 22 is greater than that of the second sliding chute 23, the first shaft body 31 extends to the first sliding chute 22, and the second shaft body 32 extends to the second sliding chute 23. In this manner, the positions of the first and

second chutes

22 and 23 can be made relatively more compact.

The first sliding chute 22 includes a first positioning section 221 and a first track section 222 which are communicated with each other, the first track section 222 includes a first chute wall which is in contact with the first shaft 31, and during the process that the door 20 rotates 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 at this time, the first shaft 31 can slide relative to the first track section 222 and slide to the first positioning section 221. During the process of opening the door 20 from the first preset angle a to the second preset angle b, the first shaft 31 can rotate relative to the first positioning segment 221, that is, at this time, 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.

It is understood that the second sliding chute 23 comprises a second positioning segment 231 and a second track segment 232 which are communicated with each other, and the second track segment 232 comprises a second chute wall which is contacted with the second shaft body 32. When the door 20 is in the closed state, the second shaft 32 is located at the second positioning segment 231, and in the process that the door 20 rotates to the first preset angle a from the closed state, the second shaft 32 can rotate relative to the second positioning segment 231, and at this time, the first shaft 31 can slide relative to the first track segment 222 and slide to the first positioning segment 221. During the process of opening the door 20 from the first preset angle a to the second preset angle b, the first shaft 31 can rotate relative to the first positioning segment 221, that is, at this time, 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 track segment 232.

In this way, when the door 20 rotates from the closed state to the first preset angle a, the second shaft 32 relatively rotates in the second positioning segment 231, the door 20 can rotate with the second shaft 32 as a rotation axis, the first shaft 31 slides to the first positioning segment 221 relative to the first trajectory segment 222, at this time, the door 20 continues to rotate, and when the door 20 opens from the first preset angle a to the second preset angle b, the first shaft 31 relatively rotates in the first positioning segment 221, the door 20 can rotate with the first shaft 31 as a rotation axis, and the second shaft 32 slides relative to the second trajectory segment 232. That is, when the door 20 rotates from the closed state to the first predetermined angle a, the door 20 rotates with the second shaft 32 as the rotation axis, and when the door 20 rotates from the first predetermined angle a to the second predetermined angle b, the door 20 rotates with the first shaft 31 as the rotation axis, and the door 20 performs two stages of diameter-variable movements during the rotation, so that the rotation center of the door 20 starts to be adjusted when the corner of the door 20 exceeds the side wall of the box 10 by a small distance, so as to avoid the cabinet or wall on the side of the refrigerator and enable the door 20 to move smoothly when the door 20 is opened.

The first track segment 222 and the second track segment 232 are arc-shaped grooves, and the arc-shaped first track segment 222 and the arc-shaped second track segment 232 play a role in guiding. The first positioning segment 221 is located at the center of the second track segment 232, and the second positioning segment 231 is located at the center of the first track segment 222.

It should be understood that, referring to fig. 8, fig. 8 is an enlarged view of a point a in fig. 5. When the door 20 is rotated from the closed state to the first predetermined angle a, that is, when the door 20 is rotated around the second shaft 32, it is required to ensure that the first side edge 214 of the door 20 (or the corner portion of the door 20) does not collide with the wall or the cabinet wall. Based on this, the distance between the groove center of the second positioning section 231 and the door front wall surface 212 is denoted as L ₁ Between the groove center of the second positioning segment 231 and the side wall surface 213 of the doorDistance is noted as L ₂ The distance between the side wall 213 of the door and the wall or the cabinet wall is denoted as L ₃ It is also understood that the distance between the axis of the second shaft 32 and the door front wall 212 when the door 21 is in the closed state is denoted by L ₁ The distance between the axis of the second shaft 32 and the door side wall 213 is L ₂ Wherein, in the step (A),

thus, when the door 20 rotates around the second shaft 32, the arc-shaped path of the first side edge 214 does not interfere with the wall or the cabinet wall.

For example, in the case of a built-in refrigerator, the distance between the side plate of the built-in cabinet and the side wall of the refrigerator is small, and is generally 2 mm to 4 mm. Based on this, in order to improve the adaptability without greatly modifying the structure of the door 20 of the existing refrigerator, the distance L between the groove center of the second positioning section 231 and the front wall surface 212 of the door may be set ₁ A distance L between the groove center of the second positioning segment 231 and the side wall surface 213 of the door, which is set between 8.5 mm and 10.5 mm ₂ Set 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 door front wall 212 is set to be smaller than the distance L between the axis of the second shaft 32 and the door front wall ₁ A distance L between the axis of the second shaft 32 and the side wall 213 of the door is set between 8.5 mm and 10.5 mm ₂ Set between 14 mm and 17 mm. In this way, it is ensured that the arc-shaped path of the first side edge 214 does not interfere with the wall or the cabinet wall when the door 20 rotates around the second shaft 32 without greatly modifying the structure of the door 20 of the existing refrigerator, such as without modifying the thickness of the door 20.

For example, the distance L between the slot center of the second positioning segment 231 and the door front wall 212 may be set to be shorter ₁ Set to 9 mm, the distance L between the groove center of the second positioning segment 231 and the side wall surface 213 of the door ₂ Set to 16 mm, since a radius of 1 mm is typically machined at first side edge 214 (at the corner of door 20), door 20 may eventually be rotated during the process of rotationA side edge 214 extends no more than 2 mm beyond the side wall of the container 10.

It can be understood that, after the door 20 moves to the first predetermined angle a by using the second shaft 32 as a rotating shaft, the door 20 moves to the second predetermined angle b by using the first shaft 31 as a rotating shaft, so as to implement two-stage diameter-variable movement of the door 20. The center distance between the first shaft 31 and the second shaft 32 is set between 9.5 mm and 12.5 mm, and when the door 20 is in the closed state, the first shaft 31 is farther away from the door sidewall surface 213 than the second shaft 32. Thus, when the door 20 is converted to move with the first shaft 31 as a rotating shaft, the installation position of the first shaft 31 can prevent the arc-shaped track 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 drawer in the storage compartment from being pulled out.

The angle range of the included angle d between the extension line of the connecting line between the center of the first shaft 31 and the center of the second shaft 32 and the extension plane of the door side wall surface 213 is 15 degrees to 25 degrees, so that the door 20 can perform two-stage diameter-changing movement more smoothly.

For ease of understanding, the following description will be made in conjunction with a specific rotational angle of door 20.

For example, the first preset angle a may be 45 degrees, and the second preset angle b may be 90 degrees, but 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, and the embodiments of the present application are not limited herein.

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

In some embodiments, the door 20 may be opened to a position greater than the second predetermined angle b (such as 90 degrees), and the refrigerator may be placed in a position with a larger accommodating space, and it can be understood that when the space is larger, the problem that the door 20 collides with the surrounding wall surface when the door 20 rotates to a position greater than 90 degrees does not need to be considered.

Referring to fig. 11, fig. 11 is a schematic structural view illustrating the door of fig. 7 being opened to a third predetermined angle. The door 20 may be opened to a third preset angle c that is greater than the second preset angle b, such as the third preset angle c may be 120 degrees. The second sliding slot 23 may further include a position-limiting segment 233 communicated with the second track segment 232, the position-limiting segment 233 is located at an end of the second track segment 232 away from the second positioning segment 231, and in a process of opening the door 20 from the second predetermined angle b to the third predetermined angle c, 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 track segment 232 to abut against a slot wall of the position-limiting segment 233. Thus, the door 20 can be restricted from rotating around the first shaft 31 by the limiting action of the limiting section 233.

It is also understood that the first sliding groove 22 cooperating with the first shaft 31 and the second sliding groove 23 cooperating with the second shaft 32 may be directly formed on the door 20. In some embodiments, the first sliding groove 22 and the second sliding groove 23 may be formed on the sliding groove member, and then the sliding groove member is installed on the position of the door 20 corresponding to the hinge 30, so as to form the first sliding groove 22 and the second sliding groove 23 on the position of the door 20 corresponding to the hinge 30.

In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.
