Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more specifically, to a refrigerator. Background Technology

[0002] Refrigerators are indispensable appliances in daily life. Common refrigerators usually have door shelves on the inner door liner for storing small items. Since different items have different heights, some refrigerators also have height-adjustable door shelves to ensure that items of varying heights can be stored on the shelves. However, traditional refrigerators typically require removing the door shelves from the inner door liner and then reinstalling them at the desired height, a cumbersome process. Utility Model Content

[0003] The purpose of this application is to provide a refrigerator that solves the technical problem of complex operation in adjusting the height of the door shelf in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a refrigerator, comprising:

[0005] The container forms a refrigerated space;

[0006] A door is rotatably mounted on the cabinet, and the door is used to open or close the refrigerated space;

[0007] The guide rails are provided in two sections, which are installed on the door body along the width direction of the door body. The guide rails are provided with multiple limiting grooves at intervals along the height direction of the door body.

[0008] A door shelf assembly includes a door shelf and adjustment mechanisms. The door shelf is provided with adjustment mechanisms on opposite sides of the door body in the width direction, and the two adjustment mechanisms are respectively provided with two guide rails. Each adjustment mechanism includes a support end and a pressing end. The support end extends into one of the limiting grooves on the corresponding guide rail to fix the adjustment mechanism on the corresponding guide rail. The pressing end is configured to drive the support end to rotate and move out of the limiting groove, so that the adjustment mechanism can move relative to the guide rail.

[0009] In one possible design, the adjustment mechanism includes a linkage structure and an elastic reset part. The pressing end and the supporting end are both disposed on the linkage structure. The linkage structure is rotatably mounted on the door shelf. The elastic reset part is connected to the door shelf and the linkage structure respectively.

[0010] Pressing the pressing end causes the connecting rod structure to rotate, so that the support end rotates out of the limiting groove; the elastic reset part is configured to drive the connecting rod structure to reset, so that the support end extends into one of the limiting grooves on the corresponding guide rail.

[0011] In one possible design, the linkage structure includes a first pivot, a second pivot, a first rod, and a second rod. The first pivot and the second pivot are spaced apart and mounted on the door shelf. The first rod is rotatably mounted on the first pivot, and the second rod is rotatably mounted on the second pivot. The first rod and the second rod are hinged together. The end of the first rod away from the second rod is designated as the pressing end, and the end of the second rod away from the first rod is designated as the supporting end.

[0012] In one possible design, the axes of both the first and second rotating shafts are parallel to the width direction of the door body.

[0013] In one possible design, the adjustment mechanism further includes a fixing member, which is fixedly installed on the door shelf. The fixing member has a first limiting end and a second limiting end, which are respectively spaced apart from the door shelf. One end of the first rotating shaft is connected to the door shelf and the other end is connected to the first limiting end. One end of the second rotating shaft is connected to the door shelf and the other end is connected to the second limiting end.

[0014] In one possible design, the door has a first side face, which faces the refrigerated space when the door is closed, and the guide rail is provided with a plurality of limiting grooves on the side facing the first side.

[0015] And / or,

[0016] The guide rail has multiple teeth, which are spaced apart along the height of the door body, and a limiting groove is formed between any two adjacent teeth.

[0017] In one possible design, the adjustment mechanism further includes a pressing part, and the door shelf forms a guide groove on each of the opposite sides of the door body in the width direction. The pressing parts of the two adjustment mechanisms are slidably installed in different guide grooves. The pressing part has a first sliding groove, and the pressing end extends into the first sliding groove. The pressing part can move along the guide groove and drive the pressing end to rotate. The pressing end is configured to move relative to the pressing part along the first sliding groove during rotation.

[0018] In one possible design, the door shelf is provided with a second sliding groove along the height direction of the door body. There are two second sliding grooves, and the two second sliding grooves are provided in a one-to-one correspondence with the two guide rails. Each guide rail passes through the corresponding second sliding groove along the height direction of the door body.

[0019] In one possible design, the second slide has a first inner wall that is opposite to the opening of the limiting groove on the guide rail, and an avoidance groove is formed on the first inner wall for avoiding the support end.

[0020] In one possible design, the door shelf includes a shelf body and two mounting boxes, the two mounting boxes being respectively installed on opposite sides of the shelf body spaced apart along the width direction of the door, and the two adjustment mechanisms being respectively disposed in different mounting boxes.

[0021] The beneficial effect of the refrigerator provided in this application is that, compared with the prior art, the door shelf in the refrigerator provided in this application is movably mounted on the guide rail through two adjustment mechanisms. By pressing the pressing end, the supporting end is driven to rotate and move out of the limiting groove, so that the adjustment structure can move relative to the guide rail, thereby allowing the door shelf to move relative to the guide rail. By moving the door shelf along the height direction of the door until the supporting end is aligned with the limiting groove corresponding to the target height, the pressing end is reset by pulling or pushing it in the opposite direction, thereby allowing the supporting end to extend into the limiting groove corresponding to the target height, and thus fixing the door shelf at the target height position.

[0022] As can be seen from the above, the refrigerator provided in this application allows for adjustment of the door shelf height simply by pressing the pressing end, without the need to disassemble or assemble the door shelf, making the operation simple and convenient.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0044] like Figures 1 to 4 As shown, one embodiment of this application provides a refrigerator, including a cabinet with a refrigeration space for storing food or other items that need to be refrigerated.

[0045] The refrigerator includes a door 100, which is rotatably mounted on the refrigerator body. The door 100 is used to open or close the refrigerator compartment. Optionally, the door 100 can be a rectangular plate structure or other shapes. For ease of description, the following description uses the rectangular plate structure of the door 100 as an example. One side of the door 100 is rotatably connected to the refrigerator body. By rotating the door 100, the refrigerator compartment can be opened or closed. The door 100 has a first side 110. When the door 100 is closed, the first side 110 faces the refrigerator compartment, and the rotation axis of the door 100 is parallel to the first side 110. It is worth noting that the height direction of the door 100 is parallel to the rotation axis of the door 100, and the width direction of the door 100 is parallel to the first side 110 and perpendicular to the rotation axis of the door 100.

[0046] The refrigerator includes two guide rails 200. The two guide rails 200 are installed on the door 100 along the width direction of the door body 100. The guide rails 200 are provided with multiple limiting grooves 220 at intervals along the height direction of the door body 100.

[0047] The refrigerator includes a door shelf assembly 300. The door shelf assembly 300 includes a door shelf 400 and adjustment mechanisms 500. Adjustment mechanisms 500 are respectively provided on opposite sides of the door body 100 in the width direction, with each adjustment mechanism 500 corresponding to one of the two guide rails 200. Each adjustment mechanism 500 includes a support end 5121 and a pressing end 5111. The support end 5121 extends into one of the limiting grooves 220 on the corresponding guide rail 200 to fix the adjustment mechanism 500 to the corresponding guide rail 200. The pressing end 5111 is configured to drive the support end 5121 to rotate and move out of the limiting groove 220, allowing the adjustment mechanism 500 to move relative to the guide rail 200.

[0048] In the refrigerator provided in this embodiment, the door shelf 400 is movably mounted on the guide rail 200 via two adjustment mechanisms 500. By pressing the pressing end 5111, the support end 5121 is rotated and moved out of the limiting groove 220, allowing the adjustment structure to move relative to the guide rail 200, thereby enabling the door shelf 400 to move relative to the guide rail 200. By moving the door shelf 400 along the height direction of the door body 100 until the support end 5121 aligns with the limiting groove 220 corresponding to the target height, the pressing end 5111 is reset by pulling or pushing it in the opposite direction, causing the support end 5121 to extend into the limiting groove 220 corresponding to the target height, thus fixing the door shelf 400 at the target height position. As can be seen from the above, the refrigerator provided in this embodiment only requires pressing the pressing end 5111 to adjust the height of the door shelf 400, eliminating the need to disassemble the door shelf 400, making operation simple and convenient.

[0049] In this embodiment, the pressing end 5111 can be pressed forward and driven back to reset by the operator, or it can be pressed forward and driven back to reset by the reset structure, or the pressing end 5111 can be pressed forward and driven back to reset by the driving mechanism. It is worth noting that pressing the pressing end 5111 forward can cause the support end 5121 to move out of the limiting groove 220, and when the pressing end 5111 is driven back to reset, the support end 5121 can extend into one of the limiting grooves 220 on the corresponding guide rail 200.

[0050] In one possible design, please refer to Figures 4 to 6The adjusting mechanism 500 includes a linkage structure 510 and an elastic reset part 520. A pressing end 5111 and a supporting end 5121 are both disposed on the linkage structure 510. The linkage structure 510 is rotatably mounted on the door shelf 400. The elastic reset part 520 is connected to both the door shelf 400 and the linkage structure 510. Pressing the pressing end 5111 causes the linkage structure 510 to rotate, thereby causing the supporting end 5121 to rotate and move out of the limiting groove 220. The elastic reset part 520 is configured to drive the linkage structure 510 to reset, causing the supporting end 5121 to extend into one of the limiting grooves 220 on the corresponding guide rail 200. In this configuration, pressing the pressing end 5111 drives the connecting rod structure 510 to rotate relative to the door shelf 400, thereby causing the support end 5121 to rotate and move out of the limiting groove 220. The elastic reset part 520 undergoes elastic deformation and stores energy. When the door shelf 400 is adjusted to the target height position, releasing the pressing end 5111 releases the energy of the elastic reset part 520 and returns it to its state before elastic deformation. The elastic reset part 520 drives the connecting rod structure 510 to reset, thereby allowing the support end 5121 to extend into the limiting groove 220 corresponding to the target height on the corresponding guide rail 200, thus fixing the door shelf 400 at the target height position. By setting the elastic reset part 520, the operator's operation of driving the pressing end 5111 to reset can be eliminated, making the operation of adjusting the height of the door shelf 400 simpler and more convenient. Optionally, the elastic reset part 520 includes, but is not limited to, a spring, a torsion spring, or a rubber component.

[0051] In one possible design, such as Figures 4 to 6 As shown in any of the attached figures, the linkage structure 510 includes a first pivot 513 and a first rod 511. The first pivot 513 is mounted on the door shelf 400, and the first rod 511 is rotatably mounted on the first pivot 513.

[0052] The linkage structure 510 includes a second rotating shaft 514 and a second rod body 512. The second rotating shaft 514 is installed on the door shelf 400, and the first rotating shaft 513 and the second rotating shaft 514 are spaced apart. The second rod body 512 is rotatably installed on the second rotating shaft 514.

[0053] The first rod 511 and the second rod 512 are hinged together. The end of the first rod 511 away from the second rod 512 is designated as a pressing end 5111, and the end of the second rod 512 away from the first rod 511 is designated as a supporting end 5121. By pressing the pressing end 5111, the first rod 511 rotates relative to the first rotating shaft 513, which in turn causes the second rod 512 to rotate around the second axis, causing the supporting end 5121 of the second rod 512 to rotate around the second axis and move out of the limiting groove 220.

[0054] Optionally, such as Figure 5As shown, a third sliding groove 5112 is provided through the first rod 511 extending along the axis of the first rotating shaft 513. The third sliding groove 5112 extends along the length of the first rod 511, and the first rotating shaft 513 passes through the third sliding groove 5112. When the first rod 511 rotates around the axis of the first rotating shaft 513, the first rotating shaft 513 slides relative to the first rod 511 along the third sliding groove 5112. Since the distance between the hinge end of the first rod 511 and the second rod 512 and the first rotating shaft 513 will change during the rotation of the second rod 512 driven by the first rod 511, the third sliding groove 5112 is provided to accommodate the change in the distance between the hinge end of the first rod 511 and the second rod 512 and the first rotating shaft 513, so that the first rod 511 can smoothly drive the second rod 512 to rotate.

[0055] In some embodiments, the elastic reset part 520 may be specifically connected to the first rod 511, for example, the elastic reset part 520 may be specifically connected to the pressing end 5111 on the first rod 511; or, the elastic reset part 520 may also be connected to the second rod 512, for example, the elastic reset part 520 may be specifically connected to the support end 5121 on the second rod 512; or, the elastic reset part 520 may also be connected to the hinge joint of the first rod 511 and the second rod 512.

[0056] In some examples, please refer to Figure 4 The elastic reset part 520 is connected to the hinge joint of the first rod 511 and the second rod 512. Specifically, the linkage structure 510 also includes a third pivot 515. The first rod 511 and the second rod 512 are respectively provided with through holes, and the third pivot 515 passes through the through holes in the first rod 511 and the second rod 512. The first rod 511 and the second rod 512 are hinged through the third pivot 515. One end of the elastic reset part 520 is fixed to the door shelf 400, and the other end is fixed to the third pivot 515. Taking the elastic reset part 520 as a spring as an example, hooks are formed at both ends of the spring, and a fixed shaft 435 is formed on the door shelf 400. One end of the spring is hooked to the fixed shaft 435, and the other end is hooked to the third pivot 515.

[0057] Optionally, please refer to Figure 5 and Figure 7The first rod 511 includes a main body 5113 and two hinged parts 5114. The two hinged parts 5114 are connected to the main body 5113 and are spaced apart along the extension direction of the third axis (the axis of the third rotating shaft 515). The two hinged parts 5114 have through holes extending along the third axis. The third rotating shaft 515 passes through the through holes in the two hinged parts 5114 and the through hole in the second rod 512. The hook on the third rotating shaft 515 can be located between the two hinged parts 5114, limiting the hook on the third rotating shaft 515 to improve the reliability of the spring hook on the third rotating shaft 515. Optionally, the end of the second rod 512 with the through hole can be located between the two hinged parts 5114 or on the side of one hinged part 5114 away from the other; this is not a unique limitation.

[0058] Optionally, the main body 5113 may be provided with the aforementioned third slide groove 5112; or, the two hinge portions 5114 may each be provided with the aforementioned third slide groove 5112; or, the main body 5113 may be provided with the aforementioned third slide groove 5112, and the two hinge portions 5114 may also each be provided with the aforementioned third slide groove 5112, with the third slide groove 5112 on the two hinge portions 5114 communicating with the third slide groove 5112 on the main body 5113.

[0059] In some embodiments, please refer to Figure 6 The door shelf 400 may be provided with an abutment portion 434, which is located on one side of the first rotating shaft 513 and is used to support the first rod 511. When the pressing end 5111 is pressed, causing the first rod 511 to rotate around the first rotating shaft 513, the first rotating shaft 513 slides relative to the first rod 511 along the third sliding groove 5112 towards the side closer to the pressing end 5111. The end of the first rod 511 away from the pressing end 5111 abuts against the abutment portion 434, which supports the first rod 511, allowing it to rotate around the first rotating shaft 513. This reduces the force exerted by the first rod 511 on the first rotating shaft 513, effectively reducing the possibility of the first rotating shaft 513 becoming misaligned, and improving the reliability of the adjustment mechanism 500.

[0060] In one possible design, the axes of the first rotating shaft 513 and the second rotating shaft 514 are both parallel to the width direction of the door body 100. In this embodiment, the first rod 511 rotates in a plane perpendicular to the first axis (the axis of the first rotating shaft 513), and the second rod 512 rotates in a plane perpendicular to the second axis (the axis of the second rotating shaft 514). By setting both the first and second axes parallel to the width direction of the door body 100, the first rod 511 and the second rod 512 both move in a plane perpendicular to the width direction of the door body 100. This effectively reduces the space occupied by the adjustment mechanism 500 in the width direction of the door body 100, thereby maximizing the space of the door shelf 400.

[0061] In some embodiments, the first axis and the second axis are spaced apart along the thickness direction of the door body 100, with the first axis located on the side of the second axis away from the door body 100. It is worth noting that the thickness direction of the door body 100 is perpendicular to both its height and width directions. This arrangement allows the pressing end 5111 to be positioned in an area of ​​the door shelf 400 relatively far from the door body 100, i.e., in a relatively outer area of ​​the door shelf 400, facilitating operator operation of the pressing end 5111 and improving the ease of adjusting the height of the door shelf 400.

[0062] In one possible design, please refer to Figures 4 to 6 The adjusting mechanism 500 also includes a fixing member 540, which is fixedly installed on the door shelf 400. The fixing member 540 has a first limiting end 5411 and a second limiting end 5421, which are respectively spaced apart from the door shelf 400. One end of the first rotating shaft 513 is connected to the door shelf 400 and the other end is connected to the first limiting end 5411. One end of the second rotating shaft 514 is connected to the door shelf 400 and the other end is connected to the second limiting end 5421. The first rod 511 is rotatably mounted on the first rotating shaft 513, and the second rod 512 is rotatably mounted on the second rotating shaft 514. The axis of the first rotating shaft 513 is the first axis, and the axis of the second rotating shaft 514 is the second axis. This configuration, with the first limiting end 5411 providing limiting support for the first rotating shaft 513 and the second limiting end 5421 providing limiting support for the second rotating shaft 514, can improve the installation stability of the first rotating shaft 513 and the second rotating shaft 514, effectively reducing the possibility of the first rotating shaft 513 tilting during the rotation of the first rod 511 and the possibility of the second rotating shaft 514 tilting during the rotation of the second rod 512.

[0063] In one example, such as Figure 4 and Figure 8As shown, the fastener 540 includes a first fixing segment 541 and a second fixing segment 542 connected to each other. The end of the first fixing segment 541 away from the second fixing segment 542 is a first limiting end 5411, and the end of the second fixing segment 542 away from the first fixing segment 541 is a second limiting end 5421. Optionally, the door shelf 400 is also provided with a first limiting part 432, which is located on the side of the first fixing segment 541 and the second fixing segment 542 that is closer to or farther from the other. For example, the first limiting part 432 is located on the side of the second fixing segment 542 that is farther from the first fixing segment 541. The first limiting part 432 can limit the second fixing segment 542, thereby limiting the entire fastener 540, improving the stability of the fastener 540 installed on the door shelf 400, and further improving the installation stability of the first pivot 513 and the second pivot 514. Alternatively, the fastener 540 can be fixed to the door shelf 400 by means of screwing, welding or gluing.

[0064] In one possible design, please refer to Figure 2 The guide rail 200 has multiple limiting grooves 220 on the side facing the first side 110 of the door 100. This arrangement ensures that when the door 100 is opened and the refrigerator compartment is open, the limiting grooves 220 are located on the side of the guide rail 200 away from the user, improving the refrigerator's aesthetics. In some examples, two mounting plates 120 are provided on the first side 110, spaced apart along the width of the door 100. Each mounting plate 120 has a guide rail 200 mounted on it, and each guide rail 200 has multiple limiting grooves 220 on the side facing the first side 110. The door shelf 400 is located between the two mounting plates 120 and is slidably connected to the two guide rails 200 via two adjusting mechanisms 500.

[0065] In one possible design, please refer to Figure 2 and Figure 6 The guide rail 200 has multiple teeth 210 spaced apart along the height direction of the door body 100, and a limiting groove 220 is formed between any two adjacent teeth 210. Optionally, the multiple teeth 210 can be provided on the side of the guide rail 200 facing the first side 110 to form multiple limiting grooves 220 on that side. Alternatively, the multiple teeth 210 can also be provided on other sides of the guide rail 200 to form multiple limiting grooves 220 on those other sides.

[0066] In one possible design, please refer to Figure 4 and Figure 6The adjustment mechanism 500 also includes a pressing part 530. The door shelf 400 has a guide groove 431 formed on each of its opposite sides in the width direction of the door body 100. The pressing parts 530 in the two adjustment mechanisms 500 are slidably installed in different guide grooves 431. The pressing part 530 has a first sliding groove 531, and the pressing end 5111 extends into the first sliding groove 531. The pressing part 530 can move along the guide groove 431 and drive the pressing end 5111 to rotate. The pressing end 5111 is configured to move relative to the pressing part 530 along the first sliding groove 531 during rotation. In this embodiment, by providing the guide groove 431 to guide the pressing part 530, the operator's pressing of the pressing part 530 becomes smoother, which is beneficial to improving the user experience of the refrigerator. By setting the first slide groove 531, the pressing part 530 can be smoothly driven to rotate during the movement of the pressing part 530. In addition, the maximum displacement of the pressing part 530 can be limited by the first slide groove 531, which effectively reduces the situation where the pressing end 5111 disengages from the pressing part 530.

[0067] In the embodiments of this application, please refer to Figure 6 The extending direction of the guide groove 431 and the extending direction of the first slide groove 531 are set at an angle. Exemplarily, the extending directions of the guide groove 431 and the first slide groove 531 are set perpendicular to each other. In one specific embodiment, the extending direction of the guide groove 431 is parallel to the height direction of the door body 100, and the extending direction of the first slide groove 531 is parallel to the width direction of the door body 100. In this embodiment, the door shelf 400 has a storage slot 413, and the opening direction of the storage slot 413 is parallel to the height direction of the door body 100. Optionally, the opening orientation of the guide groove 431 can be the same as or opposite to the opening orientation of the storage slot 413. A portion of the pressing part 530 extends into the guide groove 431 through the opening, and another portion of the pressing part 530 extends out through the opening of the guide groove 431 for the operator to press. In practical applications, the opening of the storage slot 413 is usually oriented upwards. Therefore, when the opening of the guide slot 431 is oriented in the same direction as the opening of the storage slot 413, it is convenient for the operator to press the pressing part 530, thereby improving the ease of adjusting the height of the door shelf 400.

[0068] In some embodiments, please refer to Figure 4 and Figure 6The door shelf 400 is also provided with a second limiting part 433. The openings of the second limiting part 433 and the guide groove 431 are spaced apart along the extension direction of the guide groove 431. The second limiting part 433 is used to abut against the pressing part 530. The pressing part 530 has an initial position and a pressing position. When the pressing part 530 is in the initial position, the support end 5121 is located in one of the limiting grooves 220 on the corresponding guide rail 200. By pressing the pressing part 530, the pressing part 530 moves along the guide groove 431 until it abuts against the second limiting part 433. At this time, the pressing part 530 is in the pressing position, and the support end 5121 moves out of the limiting groove 220. In this arrangement, the second limiting part 433 can limit the pressing depth of the pressing part 530, thereby effectively reducing the possibility that the pressing part 530 may get stuck due to being pressed too deeply.

[0069] In one possible design, please refer to Figure 2 , Figure 3 and Figure 9 The door shelf 400 has two second sliding grooves 412 extending along the height direction of the door body 100. Each second sliding groove 412 corresponds to one of the two guide rails 200, with each guide rail 200 passing through its corresponding second sliding groove 412 along the height direction of the door body 100. When the support end 5121 moves out of the limiting groove 220, the cooperation between the second sliding groove 412 and the guide rail 200 guides the movement of the door shelf 400 along the height direction of the door body 100. This facilitates the alignment of the support end 5121 of each adjustment mechanism 500 with the limiting groove 220 on the corresponding guide rail 200. This allows the support end 5121 to quickly align with the limiting groove 220 on the corresponding guide rail 200 after the door shelf 400 is adjusted to the target height, improving the ease of adjusting the height of the door shelf 400.

[0070] In one possible design, please refer to Figure 3 and Figure 6 The second slide groove 412 has a first inner wall, which is opposite to the opening of the upper limit groove 220 of the guide rail 200. A clearance groove 415 is formed on the first inner wall, which is used to avoid the support end 5121. Specifically, when the support end 5121 moves out of the limit groove 220, at least a part of the structure of the support end 5121 can extend into the clearance groove 415. In this way, the size of the second slide groove 412 can be adapted to the size of the guide rail 200. That is, in at least one direction perpendicular to the height direction of the door body 100, the width of the second slide groove 412 is close to the width of the guide rail 200, so that the inner wall of the second slide groove 412 can be closer to the guide rail 200, which can reduce the swaying of the door shelf 400 when moving relative to the guide rail 200 and improve the guiding effect of the door shelf 400 moving along the height direction of the door body 100.

[0071] In some embodiments, such as Figure 6 As shown, the inner wall of the clearance groove 415 and the inner wall of the second slide groove 412 have a smooth transition. In one example, the inner wall of the clearance groove 415 and the inner wall of the second slide groove 412 are rounded. This effectively reduces the collision between the support end 5121 and the inner wall of the clearance groove 415 or the inner wall of the second slide groove 412, which helps to improve the smoothness of adjusting the height of the door shelf 400.

[0072] In one possible design, please refer to Figure 2 and Figure 3 The door shelf 400 includes a shelf body 410 and two mounting boxes 420. The two mounting boxes 420 are respectively installed on opposite sides of the shelf body 410, spaced apart along the width direction of the door 100. Two adjustment mechanisms 500 are respectively housed within different mounting boxes 420. In this embodiment, the shelf body 410 forms the aforementioned storage groove 413. By providing the mounting boxes 420, the adjustment mechanisms 500 can be better protected, while also improving the aesthetics of the refrigerator.

[0073] In this embodiment, please refer to Figure 3 and Figure 10 The aforementioned fixed shaft 435, abutment part 434, guide groove 431, first limiting part 432, and second limiting part 433 are all disposed within the mounting box 420. In some embodiments, the shelf body 410 has a mounting groove 411 formed on each of its opposite sides in the width direction of the door body 100, and the two mounting boxes 420 are respectively installed in different mounting grooves 411. The mounting groove 411 and the second sliding groove 412 located on the same side of the shelf body 410 are spaced apart on one side of the shelf body 410 in the width direction of the door body 100. A first connecting opening 414 is provided through the side wall between the mounting groove 411 and the second sliding groove 412, and a second connecting opening 4212 is provided through the side wall of the mounting box 420. The first connecting opening 414 and the second connecting opening 4212 are opposite to each other. The support end 5121 of the adjustment mechanism 500 inside the mounting box 420 extends into the second slide groove 412 through the second connecting port 4212 and the first connecting port 414 in sequence, so that the support end 5121 can extend into one of the limiting grooves 220 on the guide rail 200 in the second slide groove 412.

[0074] Optionally, the mounting box 420 can be installed on the shelf body 410 by means of snap-fit, screw-fit, or adhesive. In one example, the shelf body 410 is secured to the shelf body 410 by multiple screws. In another example, such as Figure 3As shown, one of the mounting box 420 and the shelf body 410 is provided with a first buckle 4223, and the other is provided with a first slot 4111. The mounting box 420 and the shelf body 410 are connected by the snap-fit ​​of the first buckle 4223 and the first slot 4111. For ease of description, the following description will use the example of the mounting box 420 being provided with the first buckle 4223 and the shelf body 410 being provided with the first slot 4111. In one example, multiple first buckles 4223 are spaced apart on the outer peripheral surface of the mounting box 420, and multiple first slots 4111 are spaced apart on the inner wall of the mounting groove 411. The multiple first buckles 4223 are provided one-to-one with the multiple first slots 4111, and each first buckle 4223 snaps into its corresponding first slot 4111. Optionally, the mounting box 420 can be a cuboid structure, a cylindrical structure, or other irregular shape structure, and the shape of the mounting groove 411 matches the shape of the mounting box 420.

[0075] In a specific example, please refer to Figure 3 , Figure 10 and Figure 11The mounting box 420 includes a box body 421 and a cover 422. The box body 421 has a receiving groove 4211, and the adjusting mechanism 500 is installed in the receiving groove 4211. The cover 422 closes to the opening of the receiving groove 4211. The receiving groove 4211 has a bottom wall opposite to its opening and a side wall surrounding the outer periphery of the bottom wall. The second communication port 4212 is provided on the side wall of the receiving groove 4211 near the door body 100. The fixed shaft 435, the abutment part 434, the guide groove 431, the first limiting part 432, and the second limiting part 433 are all provided on the bottom wall of the receiving groove 4211. Optionally, the cover 422 includes a base plate 4221 and a frame 4222, with the frame 4222 surrounding the outer periphery of the base plate 4221. When the base plate 4221 closes to the opening of the receiving groove 4211, the frame 4222 surrounds the outer periphery of the box body 421. A fixing groove 42211 is formed on the side of the substrate 4221 facing the receiving groove 4211. One end of the fixing shaft 435 is connected to the bottom wall of the receiving groove 4211, and the other end is inserted into the fixing groove 42211. A notch 42221 is formed on one side of the frame 4222, and the notch 42221 is opposite to the second connecting port 4212 on the box body 421. Specifically, the side of the second rod 512 with the support end 5121 extends into the second sliding groove 412 through the second connecting port 4212, the notch 42221 and the first connecting port 414. By setting the frame 4222, on the one hand, the connection stability between the box body 421 and the cover body 422 can be improved; on the other hand, part of the second connecting port 4212 can be blocked, thereby reducing the area of ​​the second connecting port 4212 for the second rod 512 to extend out. By limiting the second rod 512 through the bottom wall of the notch 42221 and the bottom wall of the second connecting port 4212, the degree of shaking when the second rod 512 rotates can be reduced, effectively reducing the possibility of the support end 5121 being stuck. It is worth noting that the bottom wall of the notch 42221 specifically refers to the side wall of the notch 42221 that faces away from the substrate 4221, and the bottom wall of the second connecting port 4212 specifically refers to the side wall of the second connecting port 4212 that faces the substrate 4221.

[0076] Optionally, the distance between the bottom wall of the notch 42221 and the second rod 512 in the width direction of the door body 100 ranges from 0.3mm to 2.5mm. For example, the distance between the bottom wall of the notch 42221 and the second rod 512 in the width direction of the door body 100 can be 0.3mm, 0.4mm, 2mm, or 2.5mm, etc. When the distance between the bottom wall of the notch 42221 and the second rod 512 in the width direction of the door body 100 is 0.4mm, the length of the mounting box 420 in the width direction of the door body 100 is minimized while effectively reducing the possibility of friction between the second rod 512 and the bottom wall of the notch 42221. This minimizes the space occupied by the mounting box 420 in the width direction of the door body 100, resulting in a shorter length of the mounting groove 411 in the width direction of the door body 100. Under the premise that the length of the door shelf assembly 300 in the width direction of the door body 100 remains unchanged, the storage compartment 413 of the shelf body 410 can be increased. Optionally, the length of the adjusting mechanism 500 in the width direction of the door body 100 can also be shortened, further reducing the required length of the mounting box 420 in the width direction of the door body 100, and thus reducing the required length of the mounting groove 411 in the width direction of the door body 100, thereby increasing the length of the storage compartment 413 in the width direction of the door body 100 within a limited space. Optionally, the thickness of the sidewall of the shelf body 410 used to form the mounting groove 411 ranges from 17mm to 18mm, that is, the distance between the side of the shelf body 410 with the opening of the mounting groove 411 and the inner wall of the storage compartment 413 near that side ranges from 17mm to 18mm. For example, the thickness of the sidewall of the shelf body 410 used to form the mounting groove 411 can be 17mm, 17.8mm, or 18mm, etc.

[0077] Optionally, the first snap fastener 4223 can be disposed on the cover 422 or the box 421, and the cover 422 and the box 421 can be connected by snap-fit, adhesive, or interference fit. In a specific example, the first snap fastener 4223 is disposed on the cover 422, and is connected to the inner wall of the mounting groove 411 through the cover 422. The box 421 is located between the cover 422 and the bottom wall of the mounting groove 411, thereby limiting the box 421 within the mounting groove 411. Specifically, a plurality of first buckles 4223 are provided on the outer peripheral surface of the frame 4222 facing away from the box body 421, and the plurality of first buckles 4223 are engaged with a plurality of first slots 4111 in a one-to-one manner; a plurality of second slots 4224 are provided on the inner peripheral surface of the frame 4222 facing the box body 421, and a plurality of second buckles 4213 are provided on the outer peripheral surface of the box body 421 facing the frame 4222, and the plurality of second buckles 4213 are engaged with a plurality of second slots 4224 in a one-to-one manner, with each second buckle 4213 engaging with the corresponding second slot 4224.

[0078] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
