Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Fig. 1 is a schematic configuration diagram of a refrigeration and freezing apparatus according to an embodiment of the present invention, which shows the configuration of the refrigeration and freezing apparatus in a front view direction. Referring to fig. 1, the refrigerating and freezing apparatus 1 of the present invention includes a door 10 and a cabinet 20, and the door 10 is used for opening or closing the cabinet 20. In fig. 1, the door 10 is in a completely closed state.

The door body 10 includes a support device 11 and a door main body 12. The support means 11 are provided on the case 20. Specifically, the supporting device 11 is fixedly disposed with the case 20. The door main body 12 is provided on the supporting device 11 for opening or closing a forward opening of the storage space in the cabinet 20. The refrigerating and freezing device 1 of the embodiment shown in fig. 1 has two door bodies 12, but in an embodiment not shown, the refrigerating and freezing device 1 may also have one door body 12 or three or more door bodies 12.

The door main body 12 includes a plurality of door units 13 arranged side by side in order in the lateral direction of the door main body 12. At least one end 131 of each door unit 13 in the longitudinal direction is slidably provided embedded in the supporting device 11. The door units 13 adjacent in the lateral direction of the door main body 12 are at least partially separated and relatively rotated by an external force so that the door main body 12 is deformably slid on the outer surface of the cabinet 20 along the support 11. It should be noted that the longitudinal direction of the door main body 12 and the longitudinal direction of the door unit 13 are both parallel to the longitudinal direction of the refrigeration and freezing apparatus 1, that is, the longitudinal direction of the door main body 12 and the longitudinal direction of the door unit 13 are both vertical when the refrigeration and freezing apparatus 1 is placed in a normal working posture.

In this embodiment, each door main body 12 is composed of a plurality of door units 13 arranged side by side in sequence. The door units 13 adjacent in the lateral direction of the door main body 12 can be at least partially separated and relatively rotated by an external force. That is, during the process of opening or closing the cabinet 20 by the door main body 12, at least one side of each two door units 13 adjacent to each other in the transverse direction of the door main body 12, which faces away from the cabinet 20, may be partially separated, so that the door main body 12 may be bent, and the door main body 12 may have a deformation capability so as to be adaptive to the shape of the outer surface of the cabinet 20. For example, when the cabinet 20 is square, the door main body 12 allows relative rotational movement between each pair of adjacent door units 13 in sequence during the opening of the door, so that the respective portions of the door main body 12 are bent in sequence to smoothly slide over the corner formed between the front side and the side wall of the cabinet 20 from the front side of the cabinet 20 to the side wall of the cabinet 20.

The refrigerating and freezing device 1 of the invention is provided with a box body 20 and a door body 10, wherein a door body 12 in the door body 10 is composed of a plurality of door units 13 which are sequentially arranged in parallel along the transverse direction of the door body 12, at least one end of each door unit 13 in the longitudinal direction is embedded with a supporting device 11 in a sliding way, and the adjacent door units 13 in the transverse direction of the door body 12 can be at least partially separated and relatively rotated under the action of external force, so that the door body 12 can flexibly slide on the outer surface of the box body 20 along the supporting devices 11, the sliding of the door body 10 on the outer surface of the box body 20 along the supporting devices 11 after being installed on the box bodies 20 with various shapes is realized, and the adaptability of the door body 10 is improved. In addition, the door main body 12 can slide on the outer surface of the box body 20, so that the sliding door opening is realized, and the occupied space for opening and closing the door is reduced.

In some embodiments, each door unit 13 is a rectangular parallelepiped structure whose longitudinal direction is parallel to the longitudinal direction of the door main body 12. Specifically, as shown in fig. 1, the size and the setting height of each door unit 13 in the longitudinal direction of the door main body 12 are the same, so that the upper and lower edges of each door unit 13 are flush, the door main body 12 is ensured to have flat upper and lower edges, and the aesthetic degree of the door body 10 is improved. In addition, the size of each door unit 13 in the lateral direction of the door main body 12 is the same, so that the door main body 12 has uniform degeneration capability at each position in the lateral direction, and the aesthetic degree of the door body 10 is further ensured.

In this embodiment, each door main body 12 includes more than 5 door units 13 to ensure that the door main body 12 has a sufficiently large denaturing capability. Preferably, the number of the door units 13 per door body 12 ranges over 10 to further improve the degeneration capability of the door body 12.

In some embodiments, the door body 10 further includes a latch mechanism (not shown in FIG. 1). The locking means is provided on the door units 13 and is configured to make close contact between every two door units 13 adjacent in the lateral direction of the door body 12 when the door body 12 completely closes the cabinet 20 and to allow at least partial separation between every two door units 13 adjacent in the lateral direction of the door body 12 during the opening or closing of the cabinet 20 by the door body 12. That is, the locking device is used to open or close the connection relationship between the door units 13.

In one embodiment, the locking device may include a magnetic switch and a magnet (neither shown). Each gate unit 13 has a magnetic switch on one side in the lateral direction and a magnet on the other side. That is, the locking device is used to open or close the connection relationship between the door units 13. Specifically, taking the placing posture of the door units 13 when the door body 10 is in the completely closed state as an example, the same side of each door unit 13 in the transverse direction of the door main body 12 is a magnetic switch, and the other side is a magnet, or the same side of each door unit 13 in the transverse direction of the door main body 12 is a magnet, and the other side is a magnetic switch, so that one side of two adjacent sides between every two adjacent door units 13 is a magnet, and the other side is a magnetic switch. When the door body 10 is in a completely closed state, the magnetic switch is activated, so that every two door units 13 adjacent in the transverse direction of the door main body 12 are closely attached to each other. During the process that the door body 10 opens or closes the cabinet 20, the magnetic switch is closed, allowing each two door units 13 adjacent in the transverse direction of the door main body 12 to be separated from each other at least at the side away from the cabinet 20.

Until the door body 12 is completely moved to the front side 22 of the cabinet 20, the door body 10 is in a completely closed state, and the motor stops operating.

In this embodiment, the first transmission member 151 may include a gear. The second transmission member 132 may comprise a chain, and the first transmission member 151 and the second transmission member 132 are engaged with each other.

In addition, the second transmission member 132 may further include a rack engaged with the first transmission member 151. Of course, the first transmission member 151 and the second transmission member 132 may also include other transmission mechanisms, such as friction transmission, belt transmission, etc., and the present invention is not limited thereto, as long as the automatic door opening function of the door 10 can be realized.

In some embodiments, the heights of the second transmission pieces 132 of the respective door units 13 in the longitudinal direction of the door units 13 are the same, and the dimension of each second transmission piece 132 in the lateral direction of the door unit 13 is the same as the dimension in the lateral direction of the door unit 13.

In one embodiment, as shown in fig. 3 and 4, the second transmission members 132 of the door units 13 of one door main body 12 can be disposed separately from each other, so that when the door main body 12 slides through the corner formed between the front side 22 and the side wall 23 of the box body 20, two adjacent door units 13 at the corner can be completely separated from each other during the door opening or closing process, and can slide down the corner under the pushing of the first transmission member 151, respectively, thereby improving the smoothness during sliding. In the present embodiment, the plurality of second transmission members 132 are disposed at the same height in the longitudinal direction of the door unit 13, so that the plurality of second transmission members 132 separated from each other can be all located on the conveying path, ensuring the transmission efficiency between the plurality of second transmission members 132 and the first transmission member 151.

In another embodiment, as shown in fig. 6, the second transmission members 132 of the door units 13 of one door body 12 may be connected to form a complete conveyor belt, so that at least one side of the box 20 is abutted between every two adjacent door units 13 of the door bodies 12 in the transverse direction. When the door main body 12 slides across the corner formed between the front side 22 and the side wall 23 of the box body 20, in the door opening or closing process, the two adjacent door units 13 at the corner abut against one side of the box body 20 and separate from one side of the box body 20, so that the sliding smoothness is ensured, and the structural stability of the door main body 12 is also ensured.

In some embodiments, the door body 10 may further include a sealing portion (not shown) disposed at a side of each door main body 12 facing the cabinet 20. The sealing portion is made of a flexible sheet material, and a plurality of door units 13 of each door main body 12 are compactly arranged in the lateral direction and fixedly disposed on the sealing portion. On this basis, the sum of the dimensions of the plurality of door units 13 of each door main body 12 in the transverse direction is the same as the transverse dimension of the door main body 12, and the dimension of the sealing part in the transverse direction of the door main body 12 is not smaller than the sum of the dimensions of all the door units 13 of the door main body 12 except for the two door units 13 on the left and right sides in the transverse direction, so that the plurality of door units 13 of each door main body 12 are connected into a whole, and the sealing efficiency when the door body 10 is in a fully closed state is improved.

In some embodiments, as shown in fig. 6, the locking device of the door body 10 may further include an elastic member 16. The elastic member 16 is in the form of a sheet or a strip, and covers the side of all the door units 13 of each door main body 12 facing away from the cabinet 20. When the door main body 12 slides across the corner formed between the front side 22 and the side wall 23 of the cabinet 20, during the door opening or closing process, the two adjacent door units 13 at the corner are completely separated at least at the side facing away from the cabinet 20, and the elastic member 16 is expanded, stressed and expanded, and stores elastic potential energy. After the two adjacent door units 13 slide through the corner, the elastic member 16 releases the elastic potential energy to pull the two adjacent door units 13 tightly, so that the two adjacent door units are arranged tightly again, and the structural stability of the door main body 12 is further ensured.
