Specifically, the preset direction may be any suitable direction in the horizontal plane, such as a front-back direction, a lateral direction (or a left-right direction), and the like. When the predetermined direction is the front-rear direction, the idle state of the rack 20 may be a state retracted at the rear of the storage compartment 11, and accordingly, the use state of the rack 20 is a state in which the rack 20 is completely unfolded from the idle state to the front of the storage compartment 11. When the predetermined direction is the lateral direction, the idle state of the rack 20 may be a state retracted in one of the lateral sides of the storage compartment 11, and accordingly, the use state of the rack 20 is a state in which the rack 20 is completely unfolded from the idle state to the other lateral side of the storage compartment 11.

Fig. 2 is a schematic structural view of a storage compartment inner container and a rack in a use state according to an embodiment of the present invention, and fig. 3 is a schematic structural view of a storage compartment inner container and a rack in an idle state according to an embodiment of the present invention. In some embodiments, the predetermined direction is preferably a front-to-back direction, so as to support the rack 20 more stably by means of the inner container sidewall of the storage compartment 11, and to meet the usage habit of most users of the front-to-back telescopic rack 20.

Fig. 4 is a schematic exploded view illustrating a rack according to an embodiment of the present invention in a use state, fig. 5 is another schematic exploded view illustrating a rack according to an embodiment of the present invention in a use state, and fig. 6 is a schematic exploded view illustrating a rack according to an embodiment of the present invention in an idle state. Further, the rack 20 may include a front rod 21, a rear rod 22, and a telescoping mechanism 23. Both the front bar 21 and the rear bar 22 extend in the transverse direction, i.e. the front bar 21 and the rear bar 22 are parallel to each other. The rear rod 22 is fixedly disposed at the rear of the storage compartment 11, that is, the rear rod 22 is always kept stationary during the extension and retraction of the rack 20. The front end rod 21 is movably supported in the front-rear direction on the inner container side wall 111 of the storage compartment 11. The front end rod 21 may provide an operation portion or a force application portion to a user during the telescoping of the rack 20. The telescoping mechanism 23 is connected between the rear end rod 22 and the front end rod 21, and is configured to gradually contract when the front end rod 21 moves backward and gradually expand into a horizontal and hollow rack when the front end rod 21 moves forward.

In some embodiments, the telescopic mechanism 23 includes a first truss bar group 231 and a second truss bar group 232 hinged to each other, the first truss bar group 231 includes a plurality of first truss bars 2311 parallel to each other, the second truss bar group 232 includes a plurality of second truss bars 2321 parallel to each other, the first truss bars 2311 and the second truss bars 2321 are arranged to cross each other, and the first truss bars 2311 and the second truss bars 2321 are hinged at crossing positions thereof by a rotating shaft 233. It can be seen that the entire rack 20 is formed by hinging a plurality of rod-like members such as end rods and truss rods, and compared with the plate-like members commonly used in the prior art, the width of the rod-like members used in the present application is relatively narrow, so that not only are additional structures such as complex telescopic driving devices and transmission devices omitted, and the structure of the refrigerator 1 simplified, but also a rack for placing articles formed by the rack 20 in a use state can be ensured to have a relatively large hollow area, so that the contact area between the articles on the rack 20 and the cooling air flow is increased, and the cooling rate of the articles is further increased.

In some embodiments, the first truss bar group 231 has the same number of first truss bars 2311 as the second truss bar group 232 has the same number of second truss bars 2321. The number of the first truss bar 2311 and the second truss bar 2321 is set to enable the telescopic mechanism 23 to form a plurality of parallelograms with fixed side length and variable shape on the same section in the front-back direction when the rack 20 is in the use state. That is, the rack for placing articles formed by the rack 20 in the use state has a parallelogram-shaped hollow mesh, which can be flexibly deformed even if the side length is fixed, thereby being very convenient for the rack 20 to be freely switched between the idle state and the use state. Moreover, the object placing grid with meshes in the shape has relatively high structural strength, so that the supporting capacity of the object placing grid on objects can be improved. When the rack 20 is in an idle state, the plurality of first truss bars 2311 of the first truss bar group 231 may be closely arranged together to form a bar-shaped block, the plurality of second truss bars 2321 of the second truss bar group 232 may be closely arranged together to form another bar-shaped block, and the bar-shaped block formed by the plurality of first truss bars 2311 and the another bar-shaped block formed by the plurality of second truss bars 2321 are arranged in a vertically stacked manner.

Specifically, the plurality of parallelogram-shaped mesh openings formed by the first truss rod group 231 and the second truss rod group 232 may be arranged in a plurality of rows extending in the front-rear direction or a plurality of rows extending in the lateral direction.

Further, a plurality of triangular hollowed meshes may be formed between the end portions of the first truss bar 2311 and the second truss bar 2321 and the front end bar 21, and a plurality of triangular hollowed meshes may be formed between the end portions of the first truss bar 2311 and the second truss bar 2321 and the rear end bar 22.

In some embodiments, the lengths of the first truss bars 2311 are not exactly the same, and the lengths of the second truss bars 2321 are not exactly the same, so that each lateral end of the telescoping mechanism 23 is kept flush in the front-rear direction, thereby improving the aesthetic appearance of the rack 20 and preventing the rack 20 from interfering or rubbing with the liner sidewall of the storage compartment 11 during telescoping. Specifically, the lengths of part of the first truss bars 2311 are the same, and the lengths of part of the first truss bars 2311 are different; the lengths of the portions of the second truss bars 2321 are the same, and the lengths of the portions of the second truss bars 2321 are different.

Further, each lateral end of the telescopic mechanism 23 may be formed by a plurality of hinge points, each hinge point being formed by crossing an end of one first truss bar 2311 and an end of one second truss bar 2321 and being hinged by the rotation shaft 233. Several hinge points of the same transverse end of the telescopic mechanism 23 are in the same straight line extending in the front-rear direction.

In some embodiments, the centers of the front and rear rods 21 and 22 in the transverse direction are hinged to the centers of the front and rear ends of the telescoping mechanism 23 through the rotating shaft 233, respectively, so that the rack 20 maintains a symmetrical shape in the idle state, the use state, and the telescoping process. Accordingly, the front end bar 21 and the rear end bar 22 may be respectively opened at the centers in the lateral direction with a front connection hole 211 and a rear connection hole 221 for connecting the rotation shaft 233.

Specifically, the front center of the telescopic mechanism 23 is a position where the end of a first truss rod 2311 and the end of a second truss rod 2321 cross, and the rotating shaft 233 for hinging the end of the first truss rod 2311 and the end of the second truss rod 2321 together is fixedly arranged on the front rod 21 by plugging, screwing or other suitable means. Similarly, the center of the rear end of the telescopic mechanism 23 is also a position where the end of a first truss rod 2311 intersects with the end of a second truss rod 2321, and the rotating shaft 233 for hinging the end of the first truss rod 2311 and the end of the second truss rod 2321 together is fixedly arranged on the rear end rod 22 by plugging, screwing or other suitable means.

In some embodiments, the front rod 21 defines a front sliding slot 212 extending in the transverse direction, and the rear rod 22 defines a rear sliding slot 222 extending in the transverse direction. The front and rear ends of the telescopic mechanism 23 are connected to sliders provided in the front and rear slide grooves 212 and 222, respectively. Therefore, during the extension and retraction process of the rack 20, the front end and the rear end of the extension and retraction mechanism 23 can respectively slide in the front sliding groove 212 and the rear sliding groove 222, which facilitates the orderly and smooth extension and retraction deformation of the extension and retraction mechanism 23. Meanwhile, the supporting points between the front end rod 21 and the telescoping mechanism 23 and between the rear end rod 22 and the telescoping mechanism 23 are increased, and the structural stability and integrity of the whole rack 20 are improved. Specifically, to facilitate the hinge, the front slide groove 212 and the front coupling hole 211 may be formed on the upper surface of the front end rod 21, and the rear slide groove 222 and the rear coupling hole 221 may be formed on the lower surface of the rear end rod 22.

Further, the sliding blocks disposed in the front sliding groove 212 and the sliding blocks disposed in the rear sliding groove 222 are the rotating shafts 233 for hinging the end of a first truss bar 2311 and the end of a second truss bar 2321 together, and no sliding block is additionally disposed, thereby simplifying the structure of the rack 20. That is, the rotation shaft 233, which hinges the front end portion of a first truss bar 2311 and the front end portion of a second truss bar 2321 together, is confined in the front sliding groove 212, and the rotation shaft 233, which hinges the rear end portion of a first truss bar 2311 and the rear end portion of a second truss bar 2321 together, is confined in the rear sliding groove 222.

Specifically, the number of the front sliding grooves 212 and the number of the rear sliding grooves 222 may be two, the two front sliding grooves 212 are respectively located at both lateral sides of the center of the front end rod 21, and the two rear sliding grooves 222 are respectively located at both lateral sides of the center of the rear end rod 22. Therefore, the two front sliding grooves 212 and the two rear sliding grooves 222 can exert relatively balanced limiting and guiding effects on the telescopic mechanism 23, so that the telescopic mechanism 23 can be conveniently and smoothly deformed in a telescopic manner.

Further, the two front slide grooves 212 may be arranged symmetrically with respect to the lateral center of the front end rod 21, and the two rear slide grooves 222 may be arranged symmetrically with respect to the lateral center of the rear end rod 22. The length of the front runner 212 and the rear runner 222 is preferably the same.

In some embodiments, the two inner container sidewalls 111 of the storage compartment 11 are respectively provided with a supporting rib 112 extending in the front-back direction, and the two transverse ends of the front rod 21 and the telescoping mechanism 23 are respectively erected on the two supporting ribs 112. That is, the front rod 21 and the telescopic mechanism 23 are movably supported in the storage compartment 11 by the support rib 112. The support rib 112 may have a width sufficient to support the front end rod 21 and the telescopic mechanism 23, and an upper surface of the support rib 112 for contacting with the front end rod 21 and the telescopic mechanism 23 may be a smooth plane to reduce frictional resistance during the front-rear movement of the front end rod 21 and the telescopic mechanism 23.

Furthermore, the sidewall 111 of the inner container may further have a limiting rib located above the supporting rib 112, the limiting rib extends along the front-back direction to define a limiting groove together with the supporting rib 112, and the two horizontal ends of the front rod 21 and the telescoping mechanism 23 are equally located in the limiting groove respectively to limit the two horizontal ends of the front rod 21 and the telescoping mechanism 23 from tilting or lifting up from the supporting rib 112.

In some embodiments, the storage compartment 11 has two inner container sidewalls 111, and the rear portions of the two inner container sidewalls are provided with grooves 113 extending transversely and having upward openings. Both lateral ends of the rear end rod 22 are provided with a restricting portion 24, and the restricting portions 24 are inserted into the grooves 113 from top to bottom to restrict the front movement of the rear end rod 22. That is, the rear end rod 22 is fixed to the rear portion of the storage compartment 11 in an insertion manner. Specifically, the groove 113 may be formed at the rear end portion of the support rib 112, and the length of the groove 113 extending in the lateral direction may be equivalent to the width of the support rib 112. The limiter 24 and the rear rod 22 may be fixedly connected together by welding, clipping, gluing or other suitable means, or may be integrally formed. The restriction portion 24 has a substantially inverted L-shape, a horizontally extending section thereof being connected to the end of the rear end rod 22, and a vertically extending section thereof being inserted downward into the groove 113 and being restricted in the groove 113. When the user pushes or pulls the front rod 21 to extend or retract the retracting mechanism 23, the rear rod 22 can be kept stationary at the rear of the storage compartment 11 by the abutting action between the restricting portion 24 and the groove 113. The mating engagement between the restraint 24 and the recess 113 is preferably removable to facilitate replacement or removal of the entire rack 20.

In some embodiments, the number of racks 20 may be one, or two, three, or more.
