Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present application, and fig. 2 is an exploded view of a hinge and a door of the refrigerator shown in fig. 1. The embodiment 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-width variable temperature compartment. Of course, in some alternative embodiments, the storage compartment may also be some thawing compartment or sterilizing compartment with thawing function, which is not limited in this embodiment. The door 20 is used to open or close the storage compartment of the cabinet 10. Wherein door 20 may be hinged to cabinet 10 by 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 hinge 30 at the upper portion of the cabinet 10 and the hinge at the lower portion of the cabinet 10 being engaged with the door 20.

Wherein, the front end of the storage compartment is provided with an opening or a picking and placing opening for placing food into the storage compartment or picking food out of the storage compartment. Correspondingly, the box comprises an open end face 11 forming an opening of the storage compartment.

In some embodiments, door 20 is provided with at least two sliding grooves. The hinge 30 is connected to the case 10, and the hinge 30 has at least two shafts. Each shaft body corresponds to one chute, each shaft body is inserted into the corresponding chute, and the shaft bodies can move in the corresponding chute so that the box door 20 is rotationally connected with the box body 10. The refrigerator further includes a driving mechanism 40. The driving mechanism 40 includes a first guide 41 provided to the hinge 30 and a second guide 42 provided to the door 20. When the door 20 is rotated to a preset angle with respect to the case 10, the second guide 42 can be driven by the gravity of the door 20 to move along the surface of the first guide 41 to rotate the door 20 to open or close the case 10.

In the refrigerator in the embodiment of the application, on one hand, the track of the refrigerator door 20 in the rotating process can be adjusted through the cooperation of a plurality of shaft bodies and a plurality of sliding grooves between the refrigerator door 20 and the refrigerator body 10. On the other hand, by the cooperation of the first guide 41 and the second guide 42, the door 20 can be automatically rotated to be opened or closed when the door 20 is rotated to a preset angle. Further, it is possible to prevent the door 20 from stopping moving after the user turns to a predetermined angle and releases his hand, and a secondary operation is still required for the user to perform the opening and closing.

With continued reference to fig. 3 and 4, fig. 3 is a schematic structural view of a door of the refrigerator shown in fig. 2, and fig. 4 is a schematic structural view of a hinge of the refrigerator shown in fig. 2. Illustratively, the first guide 41 includes a first top surface 411 and at least one guide ramp 412. The first top surface 411 is disposed perpendicular to the direction of gravity. The first top surface 411 is connected to a guide slope 412 along at least one end of the circumference of the shaft body. In a direction away from the first top surface 411, the guide inclined surface 412 is inclined downward in the gravity direction, so that the second guide member 42 can be driven by the gravity of the door 20 to move along the guide inclined surface 412 to rotate the door 20.

Specifically, one guide inclined surface 412 is connected to one end of the first top surface 411 in the circumferential direction of the shaft body, or only one guide inclined surface 412 is connected to the first top surface 411.

At this time, the above-mentioned predetermined angle may be that the door 20 rotates until the second guide member 42 abuts against the guide inclined surface 412, so that the door 20 may be automatically opened or closed by forming a cam transmission structure with the guide inclined surface 412 and the second guide member 42.

Alternatively, one guide inclined surface 412 may be connected to each end of the first top surface 411 along the circumferential direction of the shaft body, or two guide inclined surfaces 412 may be connected to the first top surface 411.

At this time, the above-mentioned preset angles may include a fourth preset angle and a fifth preset angle. The fourth preset angle is that the door 20 rotates until the second guide member 42 abuts against one of the guide inclined planes 412, so that the door 20 can form a cam transmission structure through the guide inclined planes 412 and the second guide member 42 to realize an automatic door opening action. The fifth preset angle is that the door 20 rotates until the second guide member 42 abuts against one of the guide inclined planes 412, so that the door 20 can realize an automatic closing action through a wedge transmission structure formed by the guide inclined planes 412 and the second guide member 42.

Specifically, the fourth preset angle may be 48 °, 55 °, 63.2 °, 70 ° or the like between the door 20 and the case 10, which is not limited in the embodiment of the present application.

Specifically, the fifth preset angle may be 8 °, 17.5 °, 32 °, 41.7 ° or the like between the door 20 and the case 10, which is not limited in the embodiment of the present application.

In some embodiments, the second guide 42 may include a second top surface 421 and at least one sliding ramp 422. The second top surface 421 is parallel to the first top surface 411. The second top surface 421 is connected with a sliding inclined surface 422 along at least one end of the circumferential direction of the shaft body. The guide inclined surfaces 412 are inclined upward in the direction away from the second top surface 421, and each of the sliding inclined surfaces 422 is parallel to one of the guide inclined surfaces 412, so that the sliding inclined surfaces 422 can be driven by the gravity of the door to slide along the guide inclined surfaces 412 parallel to each other to rotate the door.

It will be appreciated that, due to the large weight of door 20, surface contact between first guide 41 and second guide 42 is achieved by the engagement of guide ramp 412 and slide ramp 422. Further, the first guide 41 and the second guide 42 can be more uniformly stressed and less likely to be damaged than the case where the first guide 41 and the second guide 42 are in line contact with each other. While also guaranteeing the stability and reliability of the door 20 when it is rotated.

In some embodiments, the second guide 42 includes rolling elements such as balls or needles. The rolling member can be driven by the gravity of the door 20 to roll along the guide inclined surface 412 to rotate the door 20. Further, rolling friction is formed between the first guide 41 and the second guide 42, so that the movement of the rolling member can be smoother during the rotation of the door 20.

In some embodiments, the first guide 41 may be a self-lubricating wear resistant material. For example, the first guide 41 may be ductile iron, polyoxymethylene (pom), or the like. Further, during the relative movement of the first guide 41 and the second guide 42, the degree of wear of the first guide 41 and the second guide 42 can be reduced, and the relative movement of the first guide 41 and the second guide 42 can be made smoother.

In some embodiments, the second guide 42 may be a self-lubricating, wear-resistant material. For example, the second guide 42 may be ductile iron, polyoxymethylene (pom), or the like. Further, during the relative movement of the first guide 41 and the second guide 42, the degree of wear of the first guide 41 and the second guide 42 can be reduced, and the relative movement of the first guide 41 and the second guide 42 can be made smoother.

The foregoing is some illustration of the drive mechanism 40 of the present embodiment. The following description continues with respect to the structure of the cabinet 10 and the door 20, illustrating the multi-axis hinge structure of the present embodiment.

Referring to fig. 5, fig. 5 is a cross-sectional view of the refrigerator shown in fig. 1. The case 10 includes a first sidewall 12 and a second sidewall 13 (i.e., right and left sidewalls of the case 10) disposed opposite to each other. A hinge 30 is provided on the case 10 adjacent to the first side wall 12. Alternatively, the hinge 30 is disposed on the case 10 proximate to the second sidewall 13. Of course, for a two-door refrigerator, a hinge 30 is provided near both the first side wall 12 and near the second side wall 13.

The door 20 includes a door rear wall 211, a door front wall 212, and a door side wall 213 near the hinge 30, it being understood that the door rear wall 211 faces the opening end face 11 of the case 10 when the door 20 is in the closed state. The door rear wall 211 is disposed opposite to the door front wall 212, and the door side wall 213 is connected to the door rear wall 211 and the door front wall 212. It can be appreciated that when the hinge 30 is located on the right side of the case 10, the right side surface of the case door 20 is the case door sidewall surface 213; when the hinge 30 is positioned on the left side of the cabinet 10, the left side surface of the cabinet door 20 is a cabinet door side wall surface 213. The front wall surface 212 of the door 20 and the side wall surface 213 of the door intersect to form a first side edge 214, or the front wall surface 212 of the door and the side wall surface 213 of the door intersect to form a corner of the door 20. 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.

On the basis, referring to fig. 6 to 8, fig. 6 is a schematic view of a sliding groove of the refrigerator door shown in fig. 2, fig. 7 is a schematic view of a closed state of the refrigerator door of the refrigerator shown in fig. 2, and fig. 8 is a partially enlarged view of a portion of the structure shown in fig. 7. At least two shafts of the hinge 30 include a first shaft 31 and a second shaft 32, the first shaft 31 being located between the case 10 and the second shaft 32. Specifically, the first shaft body 31 is located between the open end face 11 of the refrigerator and the second shaft body 32, or the first shaft body 31 is closer to the open end face 11 of the refrigerator than the second shaft body 32. At least two of the sliding grooves of the door 20 include a first sliding groove 22 engaged with the first shaft body 31 and a second sliding groove 23 engaged 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.

With continued reference to fig. 9 and 10, fig. 9 is a schematic diagram illustrating a state in which a door of the refrigerator shown in fig. 5 is opened to a first predetermined angle, and fig. 10 is a schematic diagram illustrating a state in which a door of the refrigerator shown in fig. 5 is opened to a second predetermined angle. 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. 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 door 20 rotates to a certain angle, the other shaft can be replaced to perform fixed-axis rotation movement, namely, the door 20 performs two sections of variable-diameter movement in the rotation process, and because the first shaft body 31 is positioned between the box body 10 and the second shaft body 32, in the process that the door 20 rotates from a closed state to a second preset angle b, the rotation radius of the corner part of the door 20 when the second shaft body 32 is used as an axis is smaller than the rotation radius of the corner part of the door 20 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 20 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 a cabinet or a wall on the side of the refrigerator can be avoided, and the door 20 can move smoothly when opening.

It will be appreciated 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 positions of the first sliding grooves 22 at the upper and lower ends of the box door 20 correspond to each other in the vertical direction, and the positions of the second sliding grooves 23 at the upper and lower ends of the box door 20 correspond to each other in the vertical direction, so that the movement of the upper and lower end parts of the box door 20 is kept consistent, and the box door 20 is opened or closed more smoothly.

It will also be appreciated that the hinge 30 includes a connection plate 33, the connection plate 33 being secured to the cabinet 10 of the refrigerator, such as the connection plate 33 being secured 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 connection plate 33. Wherein, the first shaft body 31 and the second shaft body 32 are integrally formed with the connecting plate 33. The first shaft body 31 and the second shaft body 32 may be formed as separate structures with the connection plate 33, and then assembled to the connection plate 33.

It will also be appreciated that the first shaft body 31 and the second shaft body 32 are rotatably connected to the connection plate 33 in order to allow the first shaft body 31 and the second shaft body 32 to rotate or slide in the corresponding sliding grooves more smoothly.

In order to more clearly describe the mating connection relationship between the first shaft body 31 and the first chute 22, and the mating connection relationship between the second shaft body 32 and the second chute 23, the specific structures of the first shaft body 31, the first chute 22, the second shaft body 32 and the second chute 23 will be described in detail below with reference to the accompanying drawings.

Referring to fig. 4 to 7, the first chute 22 is in communication with the second chute 23, the depth of the first chute 22 is greater than that of the second chute 23, the first shaft 31 extends to the first chute 22, and the second shaft 32 extends to the second chute 23.

In the process of opening the door 20 from the first preset angle a to the second preset angle b, the first shaft body 31 can rotate relative to the first positioning section 221, that is, the door 20 can rotate with the first shaft body 31 as a rotation axis at this time, and the second shaft body 32 can slide relative to the second chute 23.

It will be appreciated that the second runner 23 includes a second positioning segment 231 and a second track segment 232 in communication with each other, the second track segment 232 including a second slot wall in contact with the second shaft 32. When the door 20 is in the closed state, the second shaft body 32 is located at the second positioning section 231, and during the process of rotating the door 20 from the closed state to the first preset angle a, the second shaft body 32 can rotate relative to the second positioning section 231, and at this time, the first shaft body 31 can slide relative to the first track section 222 and slide to the first positioning section 221. In the process of opening the door 20 from the first preset angle a to the second preset angle b, the first shaft body 31 can rotate relative to the first positioning section 221, that is, the door 20 can rotate with the first shaft body 31 as a rotation axis at this time, and the second shaft body 32 can slide relative to the second track section 232.

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 also be appreciated that the distance between the axis of the second shaft 32 and the door front wall 212 is denoted as L when the door 20 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. Alternatively, the second shaft is when the door 20 is in the closed stateDistance L between axis of body 32 and front wall 212 of 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, the arc track of the movement of the first side edge 214 is ensured not to interfere with the wall or the cabinet wall when the door 20 rotates around the second shaft 32 without greatly changing the structure of the door 20 of the existing refrigerator, such as without changing the thickness of the door 20.

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.

As shown in fig. 5, an angle d between an extension line of a line between the center of the first shaft body 31 and the center of the second shaft body 32 and an extension surface of the door sidewall surface 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 view illustrating a state in which a door of the refrigerator shown in fig. 5 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 to abut against a 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.
