[0035] like Figures 1 to 3 As shown, an embodiment of the present invention provides a refrigerator 100 for refrigerating or freezing food or other items. The refrigerator 100 includes a box body 10 and an inner liner structure accommodated in the box body 10. The inner liner structure includes an inner liner body 20 having a receiving cavity 21 for food. The receiving cavity 21 has an open end and a closed end arranged opposite to each other in a first direction. A user can take food in and out through the open end.

[0036] Furthermore, in order to achieve the layered placement of food to increase the storage capacity of the accommodating cavity 21, the refrigerator 100 further includes at least one shelf 50 for placing food, and the inner tank structure further includes at least one set of shelf limiting components for installing the shelf 50. Specifically, a set of shelf limiting components includes two fixed ribs 40, and the two fixed ribs 40 are spaced apart and arranged on both sides of the cavity wall of the accommodating cavity 21 in a second direction perpendicular to the first direction, and each fixed rib 40 extends from an open end to a closed end along the first direction, and the opposite side edges of the shelf 50 in the second direction can be respectively limited on the two fixed ribs 40 of the same shelf limiting component.

[0037] Preferably, a plurality of groups of shelf limiting components are provided in the inner tank body 20, and the plurality of groups of shelf limiting components are arranged at intervals in a third direction which is perpendicular to both the first direction and the second direction. The refrigerator 100 also includes a plurality of shelves 50, and each shelf 50 is limited on a group of shelf limiting components.

[0038] In the present application, the first direction is the left-right direction of the refrigerator 100 (i.e. Figure 1 The second direction is the front-to-back direction of the refrigerator 100 (i.e. Figure 1 The third direction is the height direction of the refrigerator 100 (i.e. Figure 1 The front end of the shelf 50 refers to an end of the shelf 50 located at the open end of the accommodating cavity 210, and the rear end of the shelf 50 refers to an end of the shelf 50 located at the closed end of the accommodating cavity 210.

[0039] As described in the background technology, one end of the existing fixed rib is provided with a limiting groove, and one end of the shelf is formed with a limiting protrusion protruding downward, and the limiting protrusion is limited in the limiting groove, so that the movement of the shelf in the first direction can be limited. However, with the above-mentioned assembly method, a space for the limiting protrusion to move along the first direction needs to be reserved on the fixed rib to avoid interfering with the assembly of the shelf, and the setting of the moving space causes the gap of the slot for the shelf to be inserted in the third direction to be too large, so that the shelf after assembly has a large gap in the first direction, which is easy to cause the shelf to warp or shake during use, and even cause the food on the shelf to fall off, which is inconvenient for users to use.

[0040] Moreover, as large-volume refrigerators become more popular, the weight of refrigerators increases, and the resulting transportation problems are increasing. In order to prevent the shelves from being damaged during the violent handling and transportation of the refrigerator, it is usually necessary to add additional protective parts to the shelves, such as adding buffer foam to the front and back ends of the shelves, or using buffer foam for protection while fixing the left and right sides of the shelves with tape, which significantly increases unnecessary material costs and labor costs, and makes the packaging process more complicated and cumbersome, reducing packaging efficiency.

[0041] like Figure 2and Figure 4 As shown, in order to solve the above problem, two fixed ribs in the same group of fixed ribs 40 are symmetrically arranged, and each fixed rib 40 is structured to form a limiting gap extending along the first direction. The shelf limiting assembly also includes a locking tongue 47, which is matched with one end of the fixed rib 40. The locking tongue 47 can move in the first direction under the action of an external force to extend into or leave the limiting gap. When the locking tongue 47 extends into the limiting gap, the locking tongue 47 and the fixed rib 40 together form a fixed position to clamp one end of the shelf 50.

[0042] Thus, when installing the shelf 50, firstly, one end of the shelf 50 is placed on the locking tongue 47, and then the shelf 50 is pressed down to make the locking tongue 47 leave the limiting gap, and the shelf 50 without the blocking of the locking tongue 47 can enter the limiting gap. After the shelf 50 enters the limiting gap, the locking tongue 47 without the force applied by the shelf 50 re-extends into the limiting gap and forms a fixed position together with the fixing rib 40, thereby locking the shelf 50 located in the limiting gap in the third direction to prevent the shelf 50 from leaving the limiting gap in the third direction.

[0043] Since the above-mentioned inner container structure locks the shelf 50 through the locking tongue 47 provided on the fixed rib 40, compared with the technical solution in the prior art that requires a limiting protrusion to be provided on the shelf 50, there is no need to reserve a space for the limiting protrusion of the shelf 50 to move on the shelf limiting assembly, thereby avoiding a large gap in the third direction of the assembled shelf 50, thereby avoiding the shelf 50 from warping up or shaking during use. Moreover, during the transportation of the refrigerator 100, there is no need to provide other additional protective parts to provide additional protection for the shelf 50, thereby reducing the packaging cost of the refrigerator 100.

[0044] Please continue reading Figure 2 and Figure 4 Each fixed rib 40 includes a rib body 41, a first limiting unit 43 and a second limiting unit 45. The rib body 41 is formed on the cavity wall of the accommodating cavity 210 and extends from the opening end to the sealing end of the accommodating cavity 210 along the first direction. The first limiting unit 43 and the second limiting unit 45 are arranged at opposite ends of the rib body 41 in the first direction, and a limiting gap extending in the first direction is defined between the first limiting unit 43 and the second limiting unit 45. The length of the limiting gap in the first direction matches the length of the shelf 50, so that the shelf 50 can be limited in the limiting gap.

[0045] The locking tongue 47 is installed on the side of the first limiting unit 43 facing the second limiting unit 45. The locking tongue 47 can be controlled to switch between a first state of extending out of the first limiting unit 43 and a second state of retracting into the second limiting unit 45. When the locking tongue 47 is in the first state, the locking tongue 47 and the first limiting unit 43 together form a fixed position to clamp the shelf 50.

[0046] Specifically, the shelf 50 is roughly a flat plate structure. In some other embodiments, the shelf 50 may also be a fully-wrapped structure, or an assembled structure with extruded strips at the front and back. Shelves 50 of different structures do not need to be provided with raised limiting structures to be matched with the shelf limiting components.

[0047] See also Figures 5 to 8 The lock tongue 47 includes a lock tongue mounting portion 472 and a locking portion 474. The locking portion 474 is connected to one end of the lock tongue mounting portion 472 in the length direction and extends in a bent direction to the width direction of the lock tongue mounting portion 472. A lock tongue mounting hole 4721 is provided at the center of the lock tongue mounting portion 472. Two lugs 4723 are provided at one end of the lock tongue mounting portion 472 away from the locking portion 474. The two lugs 4723 are respectively provided with a lug connection hole 4723a. The end surface of one side of the locking portion 474 away from the lock tongue mounting portion 472 extends obliquely to form a guide surface 4741 that cooperates with the shelf 50.

[0048] In this way, the locking tongue 47 can be movably installed in the first limiting unit 43 through the locking tongue installation hole 4721 , and the locking portion 474 can rotate along with the locking tongue installation portion 472 to extend out of or retract into the first limiting unit 43 .

[0049] The first limiting unit 43 includes a first limiting bracket 432 , a sliding shaft 434 , an elastic return member 436 and a retaining ring 438 . The sliding shaft 434 , the elastic return member 436 and the retaining ring 438 are all assembled in the first limiting bracket 432 for adjusting the state of the locking tongue 47 .

[0050] Specifically, the first limiting bracket 432 is a hollow shell structure, having a bottom wall and a side wall extending from the edge of the bottom wall in the same direction, and the side wall surrounds the bottom wall circumferentially to form a limiting space with one end open. When the first limiting bracket 432 is installed on the fixed rib 40, the side of the side wall of the first limiting bracket 432 away from the bottom wall is in contact with the cavity wall of the accommodating cavity 210. Further, the first limiting bracket 432 is roughly "L"-shaped, including a first limiting portion 431 and a second limiting portion 433, the first limiting portion 431 extends along the first direction, and the second limiting portion 433 connects the end of the first limiting portion 431 in the first direction away from the second limiting unit 45, and extends in the third direction in a direction away from the rib body 41.

[0051] The side wall of the first limiting portion 431 is provided with two claws 4311 symmetrically arranged in the third direction, and the claws 4311 can be clamped on the cavity wall of the accommodating cavity 210 of the inner liner body 20 to fix the first limiting bracket 432 to the inner liner body 20. The first limiting portion 431 is provided with a first mounting portion 4312 and a second mounting portion 4313. The first mounting portion 4312 and the second mounting portion 4313 are arranged at intervals along the first direction, and the second mounting portion 4313 is located on a side of the first mounting portion 4312 close to the second limiting portion 433, and the first mounting portion 4312 and the second mounting portion 4313 are both provided with mounting grooves for limiting the sliding shaft 434.

[0052] The first mounting portion 4312 has a limiting slot 4317 on one side away from the second mounting portion 4313. The limiting slot 4317 extends along the first direction and penetrates through a side wall of the first limiting portion 431 facing the second limiting unit 45. A threaded mounting hole 4314 is provided in the limiting slot 4317, and the central axis of the threaded mounting hole 4313 extends along the second direction. In this way, the first limiting bracket 432 is inserted into the rib body 41 through the limiting slot 4317, and is fixedly connected to the rib body 41 through the threaded mounting hole 4314.

[0053] The bottom wall of the second limiting portion 433 is provided with a lock tongue installation shaft 4332 extending along the second direction, and the lock tongue installation shaft 4332 is used to install the lock tongue 47. The side wall of the second limiting portion 433 facing the second limiting unit 45 is provided with a lock tongue extension groove 4334, and the lock tongue 47 can pass through the lock tongue extension groove 4334 and extend out of the first limiting bracket 432.

[0054] The sliding shaft 434 includes a sliding shaft body 4341, a stopper 4343, and a hanging shaft 4345. The sliding shaft body 4341 is a cylindrical structure extending along the first direction, the stopper 4343 surrounds the sliding shaft body 4341 in the circumferential direction and is located in the middle of the sliding shaft 434, and the hanging shaft 4345 is located at one end of the sliding shaft body 4341 and protrudes from both sides of the sliding shaft body 4341 in the radial direction. In this way, the sliding shaft body 4341 is clamped on the first mounting portion 4312 and the second mounting portion 4313 of the first limiting portion 431, and the stopper 4343 can be pressed against the side of the second mounting portion 4313 facing the first mounting portion 4312.

[0055] Furthermore, the first limiting portion 431 is also provided with a rod extension slot 4316, the rod extension slot 4316 is located between the first mounting portion 4312 and the second mounting portion 4313, and the rod extension slot 4316 is waist-shaped with its length direction extending along the first direction. The sliding shaft 434 also includes a sliding shaft rod 4347, one end of the sliding shaft rod 4347 is connected to the sliding shaft 434, and the other end of the sliding shaft rod 4347 extends out of the rod extension slot 4316, and the sliding shaft rod 4347 can slide in the rod extension slot 4316 along the first direction, thereby driving the sliding shaft 434 to move along the first direction.

[0056] The retaining ring 438 is sleeved on one end of the sliding shaft body 4341 away from the hanging shaft 4345, and the elastic return member 436 is formed by a spring. The elastic return member 436 is sleeved on one end of the sliding shaft body 4341, and the opposite ends of the elastic return member 436 are respectively abutted against the retaining ring 438 and the second mounting portion 4313. The elastic return member 436 can apply a force to the sliding shaft 434 away from the second limiting unit 45 along the first direction, so that the locking tongue 47 maintains the second state.

[0057] The first limiting unit 43 is assembled as follows:

[0058] First, the lug 4723 of the locking tongue 47 is sleeved onto the hanging shaft 4345 of the sliding shaft 434 , and then the elastic reset member 436 and the retaining ring 438 are sleeved onto one end of the sliding shaft body 4341 away from the hanging shaft 4345 .

[0059] Then, the lock tongue 47 is installed on the lock tongue mounting shaft 4332 through the lock tongue mounting hole 4721, and then the lock tongue 47 is rotated so that the lock tongue 47 is limited in the second limiting portion 433, and at the same time, the retaining ring 438 and the elastic return member 436 are compressed to allow the sliding shaft 434 to be stuck in the first mounting portion 4312 and the second mounting portion 4313, the retaining ring 438 is abutted against the first mounting portion 4312, the stop portion 4343 of the sliding shaft 434 is abutted against the second mounting portion 4313, and the elastic return member 436 is abutted between the retaining ring 438 and the stop portion 4343.

[0060] Afterwards, the sliding shaft 434 pushes the locking tongue 47 to rotate under the push of the elastic reset member 436 , so that the locking portion 474 passes through the locking tongue extension slot 4334 and extends out of the first limiting bracket 432 .

[0061] Finally, the claw 4311 of the first limiting unit 43 assembled with the locking tongue 47 is inserted into the cavity wall of the accommodating cavity 210 of the inner liner body 20, and matched with the rib body 41 through the limiting groove 4317, and finally, the first limiting bracket 432 is fixed to the cavity wall of the accommodating cavity 210 by passing the fastener through the threaded mounting hole 4314.

[0062] The above-mentioned shelf 50 is installed as follows:

[0063] First, insert the rear end of the shelf 50 into the second limiting groove of the second limiting unit 45 of the fixing ribs 40 on both sides of the inner container, and the front end of the shelf 50 is freely placed on the locking tongue 47 of the first limiting unit 43 and abuts against the guide surface 4741 of the locking tongue 47.

[0064] Then, the shelf 50 is pressed down along the third direction, and the locking tongue 47 is retracted backward into the first limiting bracket 432 after being forced. At this time, the elastic reset member 436 is in a compressed state, and the front end of the shelf 50 without the blocking of the locking tongue 47 falls onto the rib body 41 and is in a horizontal state.

[0065] Finally, since the locking tongue 47 loses the force applied by the shelf 50, the elastic reset member 436 drives the sliding shaft 434 to move along the first direction, thereby driving the locking tongue 47 to rotate so that the locking portion 474 extends out of the locking tongue extension slot 4334 to lock the shelf 50 in the third direction.

[0066] The above-mentioned shelf 50 is disassembled as follows:

[0067] First, push the sliding shaft pull rod 4347 of the shelf limit assembly on one side to move along the first direction toward the second limit unit 45, thereby driving the sliding shaft 434 to overcome the force of the elastic reset member 436 and move along the first direction toward the second limit unit 45. Driven by the sliding shaft 434, the locking tongue 47 switches from the first state of extending out of the first limit bracket 432 to the second state of retracting into the first limit bracket 432, thereby contacting the fixed limit at the front end of the shelf 50. Lifting the shelf 50 can remove the limit gap on that side of the shelf 50.

[0068] Then, the other side of the shelf 50 is moved out of the limiting gap in the same manner, and finally the shelf 50 is lifted up to remove the shelf 50 from the second limiting unit 45 , thereby completing the disassembly of the shelf 50 .

[0069] The above-mentioned inner tank structure and refrigerator 100 can firmly limit the shelf 50 in the inner tank structure through the arrangement of the first limiting unit 43 and the second limiting unit 45, thereby solving the problem that the shelf 50 is easy to warp and shake, improving the user experience and safety performance, and no additional protective materials for the shelf 50 are required during transportation, thereby minimizing the additional cost of the product and greatly improving production efficiency. In addition, the shelf 50 used in the shelf limiting assembly can be designed as a flat plate in a very simple manner without adding a limiting structure. By adjusting the distance between the locking tongue 47 and the rib body 41 in the third direction and the spacing between the second limiting grooves, the installation of shelves 50 of different thicknesses and types can be achieved.

[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
