With the continuous upgrade of home decoration concept, the refrigerator is also continuously updated to meet the various demands of people on the household appliances. In the home decoration process, people require that the refrigerator or other household appliances not only exert the functions of the refrigerator or other household appliances but also be integrated with the environment, so that a home decoration concept like an embedded refrigerator appears. However, existing refrigerators are not suitable for certain scenarios.

In order to solve the above problem, embodiments of the present application provide a refrigerator, which will be described below with reference to the accompanying drawings.

For example, please refer to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of a box body in the refrigerator shown in fig. 1. The embodiment of the application provides a refrigerator 1, and the refrigerator 1 comprises a refrigerator body 10, a door body 20 and a rotating mechanism 30. The cabinet 10 has a storage space 11, and the door 20 is used to expose or close the storage space 11. The rotating mechanism 30 is connected to the box body 10 and the door body 20, and the rotating mechanism 30 includes a plurality of sets of rotating assemblies, and the plurality of sets of rotating assemblies are mutually matched, so that the door body 20 rotates relative to the box body 10 through different rotating assemblies and with different rotation centers. By providing the rotating mechanism 30 for rotating the door 20 relative to the refrigerator body 10 at different rotation centers, the door 20 can be more smoothly exposed or closed in the storage space 11 of the refrigerator body 10, and further the applicable scene of the refrigerator 1 is wider.

The refrigerator 1 can be a refrigerator 1 with a single door, double doors or multiple doors, different numbers of door bodies 20 can be arranged to correspond to different areas of the refrigerator 1, different areas can realize different functions, and the door bodies 20 with different numbers can be opened and closed without influencing the areas. The embodiment of the present application is described by taking the refrigerator 1 having a single door as an example, and should not be construed as limiting the door 20 of the refrigerator 1.

Illustratively, the cabinet 10 includes a first side 12 and a second side 13 disposed opposite to each other, and the door 20 includes a third side 21 on the same side as the first side 12. Illustratively, the third side 21 has an edge 212 remote from the housing 10. During the rotation of the door 20, the edge 212 moves toward or away from the second side 13. It can be understood that, during the rotation of the door body 20, the outermost edge 212 of the rotation shaft side of the door body 20 moves towards or away from the second side surface 13, for example, when the door body 20 is in the opening process, the edge 212 moves towards the second side surface 13, and when the door body 20 is in the closing process, the edge 212 moves away from the second side surface 13, so that the edge does not collide with or interfere with an object outside the refrigerator 1 during the opening or closing process of the door body 20. The above process can also be understood as the distance that the rotating shaft side of the door body 20 does not exceed the first side 12 of the box body 10 when rotating is too far, so that the door body 20 does not collide or interfere with the side wall in the rotating process, the refrigerator 1 is more in line with the embedded home decoration concept, and the user experience is improved.

Referring to fig. 3 in conjunction with fig. 1 and 2, fig. 3 is a schematic structural diagram of the refrigerator door body shown in fig. 1. Each set of the rotating assemblies may include hinge pins and sliding grooves that move relative to each other, and the hinge pins and the sliding grooves of the sets cooperate with each other to rotate the door 20 relative to the cabinet 10 with different hinge pins as a rotation center. It should be noted that the hinge pins of the multiple sets of rotating assemblies may be all mounted on the door body 20. Illustratively, the door body 20 includes an end cap 22 and an outer side 23, the end cap 22 is adjacent to the third side 21, and the end cap 22 is disposed at a lower portion of the door body 20. The outer side 23 is adjacent to both the end cap 22 and the third side 21, and the outer side 23 can be understood as a surface of the refrigerator 1 facing when the door 20 is closed. For example, the hinge pins may each be mounted to the end caps 22 of the door body 20 to facilitate manufacturing or to facilitate mounting or dismounting of the hinge pins. When hinge pins are provided, the hinge pins may each be provided at a corner of the end cap 22, i.e. at a position of the end cap 22 adjacent to the outer side 23 and the third side 21. The sliding grooves in the multiple groups of rotating assemblies can be all arranged on the box body 10, and the multiple groups of rotating assemblies are mutually matched to realize the rotating motion of the door body 20. Of course, the location of the hinge pin and the slide groove may have other forms, which are not illustrated here.

For example, please refer to fig. 4 in combination with fig. 1 to 3, and fig. 4 is a schematic structural diagram of a rotating mechanism in the refrigerator shown in fig. 1. The rotation mechanism 30 may include a first rotation assembly 32, a second rotation assembly 34, and a third rotation assembly 36. The first 32, second 34 and third 36 rotating assemblies include first 322, second 342 and third 362 hinge pins, respectively. In the process of the door 20 from the closed state to the fully opened state, the first rotating assembly 32, the second rotating assembly 34 and the third rotating assembly 36 are engaged with each other, so that the door 20 rotates with respect to the cabinet 10 sequentially centering on the first hinge pin 322, the third hinge pin 362 and the second hinge pin 342. In the rotation process of the door body 20, the door body 20 uses one of the first hinge pin 322, the second hinge pin 342 and the third hinge pin 362 as a rotation center, and the other two of the first hinge pin 322, the second hinge pin 342 and the third hinge pin 362 move a partial distance. It should be noted that the above process requires the hinge pin to cooperate with the sliding slot to realize the movement of the hinge pin relative to the sliding slot, and requires the cooperation between the sets of rotating assemblies to realize the rotation of the door body 20 relative to the cabinet 10.

Illustratively, the rotating mechanism 30 further includes a body 38, and the body 38 is connected to the housing 10 and extends from the housing 10 in a direction away from the housing 10.

The extension 384 may be provided with the hinge pin or the sliding groove described above. It should be noted that the mounting position of the body 38 relative to the box 10 can be located at the bottom end of the box 10, so as to facilitate the mounting of the body 38 and the rotation of the rotating mechanism 30. Wherein the body 38 can be detachably connected to the case 10, for example, the body 38 can be mounted on the case 10 by screws. Of course, the connection of the body 38 to the tank 10 can also take other forms, which are not illustrated here.

Referring to fig. 5 in conjunction with fig. 1 to 4, fig. 5 is an enlarged view of a portion B of the rotating mechanism shown in fig. 4. The first rotating assembly 32, the second rotating assembly 34 and the third rotating assembly 36 respectively further include a first sliding slot 324 corresponding to the first hinge pin 322, a second sliding slot 344 corresponding to the second hinge pin 342 and a third sliding slot 364 corresponding to the third hinge pin 362, the third sliding slot 364 is disposed at one end of the body 38 far from the box 10, the first sliding slot 324 and the second sliding slot 344 are both disposed at the body 38 at one side of the third sliding slot 364 far from the box 10, and the first sliding slot 324 and the second sliding slot 344 are disposed oppositely. For example, the first sliding groove 324 may have a circular arc shape with a middle bent away from the second sliding groove 344, the second sliding groove 344 may have a circular arc shape with a middle bent away from the first sliding groove 324, and the third sliding groove 364 may have a circular arc shape with a middle bent toward the box 10. It should be noted that the first sliding slot 324 and the second sliding slot 344 are both arc-shaped with bending, the bending angles of the first sliding slot 324 and the second sliding slot 344 may be approximately equal, the third sliding slot 364 may be arc-shaped with an approximately straight line, and the middle portion of the third sliding slot 364 may be convex toward the direction opposite to the arc-shaped, so that the third hinge pin 362 provides a stop position when moving in the third sliding slot 364.

For example, please refer to fig. 6 to 9 in combination with fig. 1 to 5, fig. 6 is a schematic structural diagram of the refrigerator shown in fig. 1 when the door body is covered, fig. 7 is a schematic structural diagram of the refrigerator shown in fig. 1 when the door body is at a first stage, fig. 8 is a schematic structural diagram of the refrigerator shown in fig. 1 when the door body is at a second stage, and fig. 9 is a schematic structural diagram of the refrigerator shown in fig. 1 when the door body is at a third stage. The process of the door body 20 from the closed state to the fully opened state may include a first stage, a second stage, and a third stage, in which the first stage door body 20 rotates by a first angle with the first hinge pin 322 as a rotation center, the second stage door body 20 rotates by a second angle with the third hinge pin 362 as a rotation center, and the third stage door body 20 rotates by a third angle with the second hinge pin 342 as a rotation center, it can be understood that the sum of the first angle, the second angle, and the third angle is an included angle between the door body 20 and the cabinet 10 when the door body 20 is fully opened. The sum of the first angle, the second angle, and the third angle may be greater than 90 °. For example, the angle between the door 20 and the cabinet 10 when the door 20 is fully opened is set to 115 °, and the sum of the first angle, the second angle, and the third angle is set to 115 °.

For example, with continued reference to fig. 5-9, the first chute 324 may include a first position 3241, a second position 3242, and a third position 3243. The second runner 344 may include a fourth position 3441, a fifth position 3442, and a sixth position 3443. Third chute 364 may include seventh position 3641, eighth position 3642, ninth position 3643. First position 3241 is adjacent to sixth position 3443, second position 3242 is between first position 3241 and third position 3243, and third position 3243 is adjacent to seventh position 3641; fourth position 3441 is adjacent to ninth position 3643 and fifth position 3442 is between fourth position 3441 and sixth position 3443; eighth position 3642 is located between seventh position 3641 and ninth position 3643.

In the process of the door 20 from the closed state to the fully opened state, that is, in the first stage, the second stage and the third stage, the door 20 drives the second hinge pin 342 to move from the fourth position 3441 to the fifth position 3442 and the third hinge pin 362 to move from the seventh position 3641 to the eighth position 3642 by using the first hinge pin 322 as the rotation center, drives the first hinge pin 322 to move from the first position 3241 to the second position 3242 and drives the second hinge pin 342 to move from the fifth position 3442 to the sixth position 3443 by using the third hinge pin 362 as the rotation center, drives the first hinge pin 322 to move from the second position 3242 to the third position 3243 and drives the third hinge pin 362 to move from the eighth position 3642 to the ninth position 3643 by using the second hinge pin 342 as the rotation center, respectively. The door body 20 has three sections of reducing diameters and three different rotating centers for rotation, so that the door body 20 can move more smoothly. It can be understood that, in the case that the opening angle of the door body 20 is the same, the more the door body 20 has the rotation center or the more the door body 20 moves in the variable diameter chute, the smoother the movement of the door body 20. The process is similar to the change from polygon to circle, because the circle is smooth arc, the infinite number of polygon edges gradually approach the circle, so that the movement of the door body 20 has no stagnation point, and the smoothness of the movement of the door body 20 is improved. The above description is only given by taking the example that the rotating mechanism 30 includes three sets of rotating assemblies, and should not be construed as limiting the movement of the door body 20.

Accordingly, the process of the door 20 from the fully opened state to the closed state may refer to the above process, that is, the process of the first stage, the second stage and the third stage in reverse order, and will not be described herein again. Of course, there is also a stage when the door body 20 is opened from the closed state to any angle or closed from any angle to the closed state, and this process is a partial process of the above process, and reference may be made to the above description, and details are not described here.
