Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of household appliances, and in particular to a refrigeration appliance. Background Art

[0002] As people's living standards continue to improve, refrigeration appliances have become an indispensable household appliance for every family. Take refrigerators as an example. Refrigerators play a vital role in our daily lives. They are essential containers for storing and preserving food. For consumers, when buying a refrigerator, they should not only consider performance such as storage, power consumption and refrigeration capacity, but also appearance. For refrigerators, multi-door refrigerators often have appearance defects such as uneven front and back doors and uneven heights.

[0003] At present, the solution of various brands to the problem of uneven front and back of multiple refrigerator doors is usually to place an additional metal nut on the side card during the injection molding of the refrigerator door and install the gap adjustment piece on the side card. When in use, the gap adjustment piece is tightened or loosened to adjust the distance between the refrigerator door and the cabinet to ensure that the multiple doors of the refrigerator are on the same plane. However, such a gap adjustment piece structure has the following three main disadvantages:

[0004] First, the edge card is formed by insert injection molding, which requires additional metal nuts to be placed during molding, which increases the manufacturing cost of the edge card itself and the cost of the injection mold. Moreover, during the injection molding process, the metal nuts need to be placed manually, which not only reduces the overall production efficiency, but also poses a safety hazard.

[0005] Secondly, metal nuts and gap adjustment parts are usually made of metal color, which does not match the overall color style of the refrigerator side card. Especially after loosening the adjustment parts, the metal threads will be directly exposed, making the relevant areas appear to be strongly separated, affecting the visual perception.

[0006] Thirdly, the clearance adjustment parts have certain safety risks: usually these adjustment parts are small in size and lack anti-drop design. Only a small force is needed to unscrew them from the side card, and they do not have a protective function against children's accidental operation. Utility Model Content

[0007] An object of the embodiments of the present utility model is to provide an improved refrigeration appliance.

[0008] Therefore, an embodiment of the utility model provides a refrigeration appliance, comprising a box body and a door, wherein the box body defines at least one storage chamber, and the door is movably connected to the box body to open or close at least a portion of the storage chamber; and further comprising: a receiving groove, which is arranged in one of the box body and the door and opens toward the other; a gap adjustment member, comprising an adjustment rod, wherein the adjustment rod includes a first section and a second section along the axial direction, and the first section can move in the receiving groove in a direction away from or close to the receiving groove to adjust the length of the portion of the second section extending outside the receiving groove; an anti-falling structure, which is used to cooperate with the receiving groove to limit the gap adjustment member from falling out of the receiving groove.

[0009] Compared with the existing gap adjustment member that can be completely rotated out from the door and fall off, the present application achieves an anti-falling effect through the cooperation of the anti-falling structure and the receiving groove, thereby preventing the gap adjustment member from falling out of the receiving groove. Specifically, the anti-falling structure interacts with the receiving groove inside the receiving groove to play an anti-falling effect. While playing an anti-falling effect, it does not affect the normal exposure of the exposed section of the gap adjustment member and is exposed outside the receiving groove, so that the user can easily operate the exposed section to achieve the function of the gap adjustment member to adjust the distance between the door and the box body. Furthermore, the anti-falling structure and the functional part of the receiving groove are hidden inside the receiving groove, and are located in a position that the user cannot touch during the daily use of the household appliance, which is conducive to extending the service life of the parts. Furthermore, for the door or box body with a receiving groove, the side of the door or box body facing the box body or door does not need to be more adaptively designed for the anti-falling structure except for the receiving groove, so that the overall appearance of the door or box body is more concise and beautiful.

[0010] Optionally, the anti-falling structure cooperates with the inner wall shape of the receiving groove to restrict the gap adjusting member from falling out of the receiving groove.

[0011] Optionally, the anti-falling structure cooperates with the inner wall shape of the receiving groove to limit the gap adjustment member from falling out of the receiving groove. As a result, the gap adjustment member can be stably maintained in the receiving groove during the adjustment process, further enhancing the anti-falling effect and improving the stability and safety of the gap adjustment member when in use. It can effectively avoid the risk of the gap adjustment member accidentally falling off during daily use, resulting in the gap adjustment member being lost, or even being swallowed by children.

[0012] Optionally, the first section has an external thread, and the gap adjustment member further includes: a sleeve portion, which is arranged in the receiving groove and sleeved on the adjusting rod, and the sleeve portion has an internal thread that matches the external thread; wherein the sleeve portion has a first end close to the opening of the receiving groove and an opposite second end, the second end is open for the adjusting rod to pass through, and the first end is provided with a stopper to limit the maximum length of the second section extending out of the receiving groove. Thus, by providing an external thread on the first section of the adjusting rod and equipping it with a sleeve portion having an internal thread, precise adjustment of the gap adjustment member is achieved. At the same time, the stopper provided at the first end of the sleeve portion limits the maximum extension length of the second section, ensuring the accuracy and safety of the adjustment process. In addition, the adjusting rod passes through the sleeve portion from the second end to complete the assembly, and the maximum distance that the adjusting rod can extend from the first end is limited by the stopper to ensure that the adjusting rod will not fall off from the sleeve portion.

[0013] Optionally, the internal thread is connected to the second end, and a non-zero gap is formed between the internal thread and the first end to form the stopper. Thus, the portion of the sleeve portion close to the opening is not provided with an internal thread, so that the stopper is naturally formed when the sleeve portion is processed, thereby achieving low complexity, easy manufacturing, and reduced cost.

[0014] Optionally, the stopper is arranged around the first end, and the diameter of the stopper is between the diameter of the first section and the diameter of the second section. Thus, the first section is blocked to prevent the adjusting rod from completely falling out of the receiving groove, and the second section is prevented from frequently rubbing against the stopper to generate loss and large resistance during the normal adjustment of the door box gap by the adjusting rod.

[0015] Optionally, the refrigeration appliance further comprises: a guide groove, which is provided in one of the sleeve portion and the receiving groove; and an adapter, which is provided in the other of the sleeve portion and the receiving groove, wherein the adapter can slide along the guide groove to guide the movement trajectory of the sleeve portion relative to the receiving groove. Thus, the provision of the guide groove and the adapter ensures a stable movement trajectory of the sleeve portion in the receiving groove, and avoids deviation and shaking during the adjustment process.

[0016] Optionally, the anti-drop structure includes: a snap portion, which is arranged on one of the sleeve portion and the groove wall of the receiving groove; and a matching portion, which is arranged on the other of the sleeve portion and the groove wall, and the matching portion is used to cooperate with the snap portion to limit the relative movement of the sleeve portion and the receiving groove. Thus, by arranging the snap portion and the matching portion between the sleeve portion and the groove wall of the receiving groove, the sleeve portion can be reliably limited in the receiving groove, and combined with the stopper portion formed by the sleeve portion itself near the opening by not arranging the internal thread, the adjusting rod is prevented from falling out of the receiving groove during the process of being screwed out, thereby increasing the firmness and stability of the connection between the sleeve portion and the receiving groove.

[0017] Optionally, the receiving groove is a blind hole, and the matching portion includes a hole portion opened on the side wall of the blind hole, thereby preventing the thermal insulation material from leaking from the receiving groove during subsequent foaming.

[0018] Optionally, the anti-falling structure includes: an end cap, which is arranged in the receiving groove, and the end cap is sleeved on the adjusting rod to limit the maximum length of the second section extending out of the receiving groove. Thus, the setting of the end cap limits the maximum extension length of the second section, effectively preventing the adjusting rod from falling out of the receiving groove, making the adjustment process more reliable.

[0019] Optionally, the end cap is provided with a stopper extending toward the adjusting rod, and a boss protruding outward is provided on one side of the second section close to the first section, and the projection of the boss along the axial direction at least partially overlaps with the stopper. Thus, the maximum movement stroke of the adjusting rod away from the accommodating groove is limited by the cooperation of the stopper and the boss.

[0020] Optionally, the receiving groove includes a third section and a fourth section, the third section is closer to the opening of the receiving groove than the fourth section, the diameter of the third section is larger than the diameter of the fourth section, and the end cover is located between the adjustment rod and the third section. Thus, the receiving groove is configured to be in the shape of large and small holes, the small hole section (i.e., the fourth section) can cooperate with the adjustment rod to adjust the gap between the door and the box body, and the large hole section (i.e., the third section) provides space for accommodating the end cover. Furthermore, the large hole section is located in front of the small hole section, which ensures that the adjustment rod has enough axial movement space to reliably adjust the gap within the effective door-box gap adjustment range, and on the other hand, it can reliably prevent it from falling off.

[0021] Optionally, the end cap and the third section have matching external threads and internal threads, respectively, and the first section and the fourth section have matching external threads and internal threads, respectively, wherein the pitch of the internal threads of the third section and the fourth section is equal. Thus, it can be ensured that the core pulling mechanism can be removed once during the molding process to form the receiving groove, reducing the manufacturing difficulty.

[0022] Optionally, the end face of the end cover facing away from the receiving groove is flush with the surface where the opening of the receiving groove is located, and the end face is provided with at least one notch. Thus, the end face is flush with the surface of the door or box body where the receiving groove is provided, which is conducive to improving the appearance of the door or box body. Furthermore, since the overall appearance surface of the end cover is flush with the outer surface of the door or box body after normal installation, it cannot be removed by conventional means, so a specific tool is inserted into the notch and rotated to unscrew it, which also makes the overall structure safer, thereby preventing other risks caused by the adjustment rod or the end cover falling off.

[0023] Optionally, the second section is wrapped with elastic material at least at the end, so that the elastic material can play a buffering role during the opening and closing process of the refrigerator door, thereby preventing the gap adjustment member from hitting the box body and causing damage to the box body structure.

DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] Figure 1 It is a schematic diagram of a refrigeration appliance 100 according to an embodiment of the present utility model.

[0040] The refrigeration appliance 100 described in this embodiment can be, for example, a refrigerator, a freezer, etc. Taking a refrigerator as an example, the refrigerator of this embodiment can be any one of a single-door refrigerator, a multi-door refrigerator, and a side-by-side refrigerator. In modern homes, in order to more reasonably divide the storage space, the refrigerator can be designed as a multi-door refrigerator or a side-by-side refrigerator. The structure of each door 102 of such refrigerators can be basically the same, so the following only takes the structure of one of the doors 102 of the refrigerator as an example for exemplary display and description.

[0041] Furthermore, the refrigeration appliance 100 further includes a box 101, and the box 101 defines at least one storage chamber 103. The storage chamber 103 may be, for example, a freezer, a refrigerator, a temperature-changing chamber, etc. It is worth noting that since the refrigeration appliance 100 described in the present application does not make any changes to the structure of the box 101, the box 101 is simplified in the accompanying drawings to better illustrate the specific structural design of the door 102.

[0042] For ease of description, in this embodiment, the width direction of the door 102 is recorded as the x direction, the thickness direction is recorded as the y direction, and the height direction is recorded as the z direction. In this embodiment, the front-to-back direction refers to the direction when the door 102 closes the storage chamber 103 and the opposite direction, wherein the front or front side refers to the direction facing the user when the refrigeration appliance 100 is in use, and the rear or rear side refers to the direction away from the user when the refrigeration appliance 100 is in use.

[0043] refer to Figure 1 , the refrigeration appliance 100 described in this embodiment may be, for example, a refrigerator.

[0044] In some embodiments, the refrigerator may include a housing 101 and a door 102, wherein the door 102 is located at the front of the housing 101 to open or close a storage chamber 103 in the housing 101. The storage chamber 103 may include partitions with different temperatures to store food and other items with different storage conditions.

[0045] Further, the door 102 may include a front panel 107, an inner liner 106 facing the box body 101 when the door 102 is closed, and a frame arranged along the four sides of the door 102. In some embodiments, the front panel 107 may be a glass plate or a ceramic plate. The frame may include an upper side card 104 and a lower side card arranged opposite to each other along the z direction, and a left side frame and a right side frame arranged opposite to each other along the x direction.

[0046] Furthermore, the door 102 may include an insulating space 105 filled with an insulating material. When the door 102 closes the storage chamber 103, the insulating layer formed by the insulating space 105 has the effect of isolating heat to ensure that the storage chamber 103 has a better refrigeration / freezing effect. The insulating material may be, for example, a foaming agent. Thus, on the one hand, the foaming agent can firmly bond the inner liner 106 of the door 102 and the front panel 107 after foaming and curing. On the other hand, the foamed insulating material can fill the entire insulating layer, which can improve the cold-keeping performance and reduce energy consumption.

[0047] Furthermore, the refrigeration appliance 100 also includes: a receiving groove 1, which is arranged in one of the box body 101 and the door 102 and is open toward the other one; a gap adjustment member 2, including an adjustment rod 21, and the adjustment rod 21 includes a first section 211 and a second section 212 along the axial direction (for example, parallel to the y direction), and the first section 211 can move in the receiving groove 1 in a direction away from or close to the receiving groove 1 to adjust the length of the portion of the second section 212 extending outside the receiving groove 1; an anti-falling structure 3, which is used to cooperate with the receiving groove 1 to limit the gap adjustment member 2 from falling out of the receiving groove 1.

[0048] Specifically, refer to Figures 2 to 4In some embodiments, the receiving slot 1 may be disposed on the door 102 and open toward the box body 101. More specifically, the receiving slot 1 may be provided on the upper side card 104. For example, the receiving slot 1 and the hinge hole 108 may be disposed at opposite ends of the upper side card 104 along the x direction, wherein the hinge hole 104 is used to receive the hinge shaft of the hinge, and the door 102 is rotatably connected to the box body 101 through the hinge.

[0049] Further, regarding the first section 211 and the second section 212 of the adjustment rod 21, the first section 211 may, for example, refer to a portion that can move within the receiving slot 1. The first section 211 may move in a direction away from or close to the receiving slot 1 as needed. This movement allows the length of the second section 212 (i.e., the portion extending outside the receiving slot 1) to change. The second section 212 is a portion that the user can directly operate. By rotating or pushing and pulling the second section 212, the user can control the position of the first section 211 within the receiving slot 1, thereby adjusting the gap between the door 102 and the box body 101.

[0050] In some embodiments, the portion of the second section 212 extending out of the receiving slot 1 can be recorded as an exposed section 214. The extent to which the second section 212 extends out of the opening of the receiving slot 1 is adjusted by the relative movement of the first section 211 and the receiving slot 1, and the extent of the extension is the length of the exposed section 214. The longer the length of the exposed section 214 is, the larger the gap between the door 102 and the box body 101 when the door 102 closes the storage chamber 103.

[0051] Furthermore, the length of the first section 211 is not less than the effective door box gap adjustment range that is planned when the refrigeration appliance 100 is designed.

[0052] Furthermore, the anti-drop structure 3 can be closely matched with the receiving groove 1 to limit the maximum movement range of the gap adjustment member 2 by physical or mechanical means to prevent it from accidentally falling out of the receiving groove 1.

[0053] From the above, the anti-falling effect is achieved by the cooperation of the anti-falling structure 3 and the receiving groove 1, so as to prevent the gap adjustment member 2 from falling out of the receiving groove 1. Specifically, the anti-falling structure 3 acts with the receiving groove 1 inside the receiving groove 1 to play an anti-falling effect, and does not affect the normal exposure of the exposed section 214 of the gap adjustment member 2 and exposes it outside the receiving groove 1 while playing the anti-falling effect, so that the user can easily operate the exposed section 214 to achieve the function of the gap adjustment member 2 adjusting the distance between the door 102 and the box body 101. Further, the anti-falling structure 3 and the functional part of the receiving groove 1 are hidden inside the receiving groove 1, and are located in a position that the user cannot touch during the daily use of the household appliance, which is conducive to extending the service life of the parts. Further, for the door 102 or the box body 101 provided with the receiving groove 1, the side of the door 102 or the box body 101 facing the box body 101 or the door 102 does not need to be more adaptively designed for the anti-falling structure 3 except for the receiving groove 1, so that the overall appearance of the door 102 or the box body 101 is more concise and beautiful. Optionally, the anti-falling structure 3 cooperates with the inner wall shape of the receiving groove to restrict the gap adjusting member 2 from falling out of the receiving groove 1 .

[0054] In a specific implementation, continue to refer to Figure 3 and Figure 4 The anti-drop structure 3 cooperates with the inner wall shape of the receiving groove 1 to prevent the gap adjusting member 2 from falling out of the receiving groove 1. As a result, the gap adjusting member 2 can be stably kept in the receiving groove 1 during the adjustment process, further enhancing the anti-drop effect and improving the stability and safety of the gap adjusting member 2 when in use. It can effectively avoid the risk of the gap adjusting member 2 accidentally falling off during daily use, resulting in the gap adjusting member 2 being lost, or even being swallowed by children.

[0055] In one specific implementation, reference Figures 5 to 7, the first section 211 has an external thread. Further, the gap adjusting member 2 also includes: a sleeve portion 22, which is arranged in the receiving groove 1 and sleeved on the adjusting rod 21, and the sleeve portion 22 has an internal thread that matches the external thread; wherein the sleeve portion 22 has a first end 221 close to the opening of the receiving groove 1 and an opposite second end 222, the second end 222 is open for the adjusting rod 21 to pass through, and the first end 221 is provided with a stopper 223 to limit the maximum length of the second section 212 extending out of the receiving groove 1. Thus, by providing an external thread on the first section 211 of the adjusting rod 21 and equipping the sleeve portion 22 with an internal thread, the precise adjustment of the gap adjusting member 2 is achieved. At the same time, the stopper 223 provided at the first end 221 of the sleeve portion 22 limits the maximum extension length of the second section 212, ensuring the accuracy and safety of the adjustment process. In addition, the adjusting rod 21 is assembled by passing through the sleeve portion 22 from the second end 222 , and the maximum distance that the adjusting rod 21 can extend from the first end 221 is limited by the stop portion 223 to ensure that the adjusting rod 21 will not fall off from the sleeve portion 22 .

[0056] Specifically, the sleeve portion 22 can be connected and fixed to the inner wall of the receiving groove 1 through the anti-falling structure 3 .

[0057] Furthermore, the external thread provided on the first section 211 allows the adjusting rod 21 to be movably connected to the sleeve portion 22 through the threaded structure, so as to adjust the gap. The user can rotate the second section 212 of the adjusting rod 21 (i.e., the part exposed outside the receiving groove 1, i.e., the aforementioned exposed section 214) to move the first section 211 in the sleeve portion 22, thereby fine-tuning the gap between the door 102 and the box body 101. Furthermore, the matching design of the internal and external threads ensures the stable movement of the adjusting rod 21 in the sleeve portion 22, while providing a convenient adjustment function.

[0058] Further, combined with Figure 3 , Figure 4 and Figure 6 , along the y direction, the sleeve portion 22 has a first end 221 and a second end 222 relatively, and the first end 221 is closer to the opening of the receiving groove 1 than the second end 222. Further, a first through hole structure 225 extending along the y direction is formed between the first end 221 and the second end 222. The stopper 223 located at the first end 221 can be formed on the inner wall of the first through hole structure 225. As the second section 212 gradually extends out of the receiving groove 1 (that is, the length of the exposed section 214 gradually increases), the external thread formed on the first section 211 gradually approaches the stopper 223. Figure 4As shown, when the protrusion structure in the external thread contacts the stopper 223 , the stopper 223 can prevent the first section 211 from continuing to rotate along the thread, thereby limiting the maximum length of the second section 212 extending out of the receiving groove 1 .

[0059] In some embodiments, the internal thread of the sleeve portion 22 is connected to the second end 222, and there is a non-zero gap between the internal thread and the first end 221 to form the stopper 223. Therefore, the portion of the sleeve portion 22 close to the opening is not provided with an internal thread, so that the stopper 223 is naturally formed when the sleeve portion 22 is processed, which reduces complexity, facilitates manufacturing, and reduces costs.

[0060] During assembly, the second section 212 and the first section 211 of the adjusting rod 21 enter the first through hole structure 225 from the second end 222 of the sleeve portion 22, wherein before the first section 211 extends into the first through hole structure 225, the movement of the adjusting rod 21 in the first through hole structure 225 is roughly parallel to the y direction, and after the first section 211 reaches the second end 222, the external thread of the first section 211 and the internal thread of the sleeve portion 22 match, and then the adjusting rod 21 rotates with the y direction as the axis while continuing to move in the y direction until the first section 211 completely enters the first through hole structure 225, at which time the adjusting rod 21 and the sleeve portion 22 are assembled into a component. Then, the component is installed into the receiving groove 1 in the opposite direction of the y direction.

[0061] In some embodiments, the diameter of the first segment 211 may be greater than the diameter of the second segment 212. Figure 3 The perspective shown is the dimension from the uppermost end of the first segment 211 including the external threads to the lowermost end including the external threads in the z direction. The diameter of the second segment 212 may include the thickness of the elastic material 215 sleeved thereon.

[0062] Furthermore, the stopper 223 is arranged around the first end 221, and the diameter of the stopper 223 is between the diameter of the first section 211 and the diameter of the second section 212. The stopper 223 may be, for example, a flange formed by folding the end of the first through-hole structure 225 close to the first end 221 inwardly. The diameter of the stopper 223 may, for example, refer to the diameter of the first through-hole structure 225 at the flange. In this way, it is ensured that the first section 211 is blocked to prevent the adjustment rod 21 from completely falling out of the receiving groove 1, and it is also prevented that the second section 212 and the stopper 223 frequently rub against each other to generate loss and large resistance during the normal adjustment of the door box gap by the adjustment rod 21.

[0063] Furthermore, the refrigeration appliance 100 further includes: a guide groove 11, which is provided in one of the sleeve portion 22 and the receiving groove 1; and an adapter portion 224, which is provided in the other of the sleeve portion 22 and the receiving groove 1, wherein the adapter portion 224 can slide along the guide groove 11 to guide the movement trajectory of the sleeve portion 22 relative to the receiving groove 1. Thus, the provision of the guide groove 11 and the adapter portion 224 ensures a stable movement trajectory of the sleeve portion 22 in the receiving groove 1, and avoids deviation and shaking during the adjustment process.

[0064] In some embodiments, reference Figure 2 , Figure 6 and Figure 7 The guide groove 11 is provided on the inner wall of the receiving groove 1, and the adapter portion 224 can be, for example, a protrusion provided on the sleeve portion 22. When the sleeve portion 22 is inserted into the receiving groove 1 in the opposite direction of the y direction, the adapter portion 224 can be inserted into the guide groove 11 and move in the guide groove 11 in the opposite direction of the y direction until the sleeve portion 22 is installed in place.

[0065] In a variation, the number of the adapter parts 224 can be multiple, and the multiple adapter parts 224 are arranged at intervals on the outer wall of the sleeve part 22. Correspondingly, the number of the guide grooves 11 can also be multiple. The multiple adapter parts 224 correspond to the multiple guide grooves 11 one by one, and the corresponding adapter parts 224 and guide grooves 11 cooperate with each other to play a fool-proof role, ensuring the stable movement trajectory of the sleeve part 22 in the receiving groove 1, and avoiding deviation and shaking during the adjustment process.

[0066] Furthermore, the anti-drop structure 3 includes: a snap portion 31, which is arranged on one of the sleeve portion 22 and the groove wall (also called the inner wall) of the receiving groove 1; and a matching portion 32, which is arranged on the other of the sleeve portion 22 and the groove wall, and the matching portion 32 is used to cooperate with the snap portion 31 to limit the relative movement of the sleeve portion 22 and the receiving groove 1. Thus, by arranging the snap portion 31 and the matching portion 32 between the sleeve portion 22 and the groove wall of the receiving groove 1, the sleeve portion 22 can be reliably limited in the receiving groove 1, and combined with the stopper 223 formed by the sleeve portion 22 itself near the opening by not arranging the internal thread, the adjusting rod 21 is prevented from falling out of the receiving groove 1 during the process of being screwed out, thereby increasing the firmness and stability of the connection between the sleeve portion 22 and the receiving groove 1.

[0067] Continue to refer Figure 2 , Figure 6 and Figure 7, the buckle portion 31 can be arranged on the sleeve portion 22, and the matching portion 32 can be arranged on the groove wall. The buckle portion 31 can be a hook extending outward, and grooves are formed on both sides of the hook so that there is a certain deformation space for the hook when the sleeve portion 22 is pushed into the receiving groove 1 in the opposite direction of the y direction, so that the user can install the sleeve portion 22 into the receiving groove 1 with a small force. The receiving groove 1 is a blind hole, and the matching portion 32 includes a hole portion 321 opened on the side wall of the blind hole. When the sleeve portion 22 is installed in place, the buckle portion 31 can be inserted into the hole portion 321 to limit the relative displacement of the sleeve portion 22 and the receiving groove 1 in the y direction.

[0068] In some embodiments, the hole portion 321 may be a through hole. In an installation scenario, when the door 102 is assembled to be filled with a foaming agent, a tape may be first pasted on the outside of the through hole (i.e., the side facing the insulation space 105) to seal the through hole to prevent the foaming agent from leaking during the foaming process.

[0069] In some embodiments, the hole 321 may also be a blind hole. Thus, it is also possible to ensure that the sleeve portion 22 is reliably fixed while preventing the foaming agent from leaking when the door 102 is foamed.

[0070] In a typical application scenario, the above Figures 1 to 7 The assembly process of the gap adjustment member 2 in the illustrated embodiment may include the following steps:

[0071] First, the second section 212 of the adjusting rod 21 is extended from the second end 222 of the sleeve portion 22 into the interior of the sleeve portion 22 until the external thread of the adjusting rod 21 contacts the internal thread of the sleeve portion 22 .

[0072] Then, the portion of the adjusting rod 21 exposed outside the sleeve portion 22 (which may be the first section 211 provided with the external thread, or the second section 212 that has extended from the first end 221) is screwed to gradually couple the internal thread and the external thread. When the first section 211 of the adjusting rod 21 is completely accommodated in the first through hole structure 225 of the sleeve portion 22, the screwing action is stopped.

[0073] Furthermore, the assembly consisting of the sleeve portion 22 and the adjusting rod 21 is inserted into the receiving groove 1 from the opening of the receiving groove 1 along the opposite direction of the y direction. During this process, the guide groove 11 and the adapter portion 224 need to be aligned with each other to avoid deviation in the insertion direction of the sleeve portion 22.

[0074] Finally, the sleeve portion 22 is pushed in the opposite direction of the y direction until the buckle portion 31 and the matching portion 32 are locked with each other. Thus, the assembly of the gap adjustment member 2 is completed. In the subsequent use process, the length of the exposed section 214 can be adjusted by screwing the second section 212 of the adjustment rod 21 to achieve fine adjustment of the gap between the door 102 and the box body 101. In addition, during the adjustment of the gap, the maximum length of the exposed section 214 is limited by the cooperation of the stopper 223 and the external thread on the first section 211, so as to prevent the gap adjustment member 2 from falling off.

[0075] In some embodiments, after the sleeve portion 22 is installed in the receiving slot 1, the buckle portion 31 hooks the mating portion 32, making it difficult for the sleeve portion 22 to be pulled out of the receiving slot 1, thereby ensuring that the adjustment rod 21 will hardly fall out of the receiving slot 1 unexpectedly.

[0076] In a specific implementation, the first end 221 of the sleeve portion 22 can be turned outward, and the corresponding receiving groove 1 is also designed with a step structure near the opening, and the two cooperate to limit the maximum movement stroke of the sleeve portion 22 when it extends into the receiving groove 1. In this way, it can be avoided that the gap adjustment member 2 is moved toward the door 1 by external force during the assembly process and daily use of the refrigeration appliance 100, which affects the adjustment effect of the length of the exposed section 214 on the gap gap.

[0077] Figure 8 It is a partial exploded view of a refrigeration appliance 100 according to the second embodiment of the present application. Figure 8 In the embodiment, only the specific structure of the upper side card provided with the gap adjustment member 2 is exemplarily shown. For other structures of the refrigeration appliance 100 described in the second embodiment, reference may be made to Figure 1 Example shown.

[0078] refer to Figure 8 The anti-falling structure 3 includes: an end cap 33, which is arranged in the receiving groove 1, and the end cap 33 is sleeved on the adjusting rod 21 to limit the maximum length of the second section 212 extending out of the receiving groove 1. Therefore, the setting of the end cap 33 limits the maximum extension length of the second section 212, effectively preventing the adjusting rod 21 from falling out of the receiving groove 1, making the adjustment process more reliable.

[0079] Further, combined with Fig. 9 , Fig.10 and Fig.12 The end cover 33 has a third end 332 and a fourth end 333 opposite to each other, wherein when the end cover 33 is assembled, the third end 332 is accommodated in the receiving groove 1 and the fourth end 333 is exposed outside the receiving groove 1 .

[0080] Furthermore, the end cover 33 has a second through hole structure 335 extending along the y direction for the adjustment rod 21 to pass through.

[0081] Further, combined with Figures 9 to 12 The end cover 33 is provided with a stopper 331 extending toward the adjusting rod 21, and a boss 213 protruding outward is provided on the side of the second section 212 close to the first section 211, and the projection of the boss 213 along the axial direction (for example, the y direction) at least partially overlaps with the stopper 331. The stopper 331 is closer to the fourth end 333 than the third end 332, so that the maximum movement stroke of the adjusting rod 21 away from the receiving groove 1 is limited by the cooperation of the stopper 331 and the boss 213.

[0082] In a variation, the diameter of the second section 212 may be smaller than the diameter of the first section 211 to form a step structure at the connection between the first section 211 and the second section 212 . The step structure may also cooperate with the stop portion 331 to limit the maximum movement range of the adjusting rod 21 away from the accommodating groove 1 .

[0083] Further, the receiving groove 1 includes a third section 12 and a fourth section 13, the third section 12 is closer to the opening of the receiving groove 1 than the fourth section 13, the diameter of the third section 12 is larger than the diameter of the fourth section 13, and the end cover 33 is located between the adjusting rod 21 and the third section 12. Thus, the receiving groove 1 is configured to be in the shape of large and small holes, the small hole section (i.e., the fourth section 13) can cooperate with the adjusting rod 21 to play a role in adjusting the gap between the door 102 and the box body 101, and the large hole section (i.e., the third section 12) provides space for accommodating the end cover 33. Further, the large hole section is located in front of the small hole section in the direction toward the box body, which ensures that the adjusting rod 21 has enough axial movement space to reliably adjust the gap within the effective door-box gap adjustment range, and reliably prevents it from falling off.

[0084] Furthermore, the end cap 33 and the third section 12 have matching external threads and internal threads, respectively, and the first section 211 and the fourth section 13 have matching external threads and internal threads, respectively, wherein the pitch of the internal thread of the third section 12 and the internal thread of the fourth section 13 are equal. In other words, there is at least one non-standard thread in the two coaxial internal threads of the third section 12 and the fourth section 13 with different diameters. Thus, it can be ensured that the core pulling mechanism can be disengaged at one time to form the receiving groove 1 during the molding process, reducing the manufacturing difficulty.

[0085] Further, refer to Fig. 9 and Fig.10 The end surface of the end cover 33 facing away from the receiving groove 1 (i.e., the end surface of the fourth end 333) is flush with the surface where the opening of the receiving groove 1 is located (e.g., the surface of the upper side card 104 facing the box body 101). Further, the end surface is provided with at least one notch 334, such as Fig.12As shown. As a result, the end surface is flush with the surface of the door 102 or the box body 101 where the receiving groove 1 is set, which is conducive to improving the appearance of the door 102 or the box body 101. Furthermore, since the overall appearance surface of the end cover 33 is flush with the outer surface of the door 102 or the box body 101 after normal installation, it cannot be removed by conventional means. Therefore, a specific tool (for example, pointed tweezers) is inserted into the notch 334 and rotated to unscrew it, which also makes the overall structure safer, thereby preventing other risks caused by the adjustment rod 21 or the end cover 33 falling off.

[0086] In a typical application scenario, the assembly process of the gap adjustment member 2 described in the second embodiment may include the following steps.

[0087] First, insert the first section 211 of the adjusting rod 21 into the receiving groove 1, and screw the second section 212 to make the external thread of the first section 211 match with the internal thread of the fourth section 13 of the receiving groove 1, so that the first section 211 gradually penetrates into the fourth section 13 of the receiving groove 1.

[0088] Then, the end cap 33 is sleeved on the second section 212 of the adjusting rod 21, and the second section 212 of the adjusting rod 21 passes through the second through hole structure 335. The end cap 33 is gradually pushed toward the receiving groove 1 until the third end 332 of the end cap 33 contacts the inner wall of the receiving groove 1.

[0089] Furthermore, the end cover 33 is screwed with a tool so that the external thread provided on the end cover 33 and the internal thread provided on the inner wall of the third section 12 are coupled.

[0090] Finally, continue to screw the end cap 33 until the end surface of the end cap 33 facing away from the receiving slot 1 is flush with the opening surface of the receiving slot 1. In subsequent use, the length of the exposed section 214 can be adjusted by screwing the second section 212 of the adjustment rod 21 to achieve fine adjustment of the gap between the door 102 and the box body 101.

[0091] In some embodiments, during disassembly, it is necessary to first use a special tool to unscrew the end cover 33 before the adjusting member 21 can be pulled out of the receiving groove 1 .

[0092] In a variation, the end cover 33 may be sleeved on the second section 212 first, and then the adjusting rod 21 may be inserted into the receiving groove 1 from the first section 211. After the first section 211 is at least partially screwed into the fourth section 13, the end cover 33 is screwed until the fourth end 333 of the end cover 33 is flush with the surface of the upper side clip 104 facing the box body 101.

[0093] In some embodiments, reference Figures 3 to 5 , Figures 9 to 11The second section 212 of the adjusting rod 21 is at least wrapped with an elastic material 215 at the end. Therefore, the elastic material 215 can play a buffering role during the opening and closing process of the refrigerator door 102, preventing the gap adjusting member 2 from hitting the box body 101 and causing damage to the box body 101 structure.

[0094] Furthermore, the outer periphery of the elastic material 215 is provided with a recessed portion 2151 (refer to Figure 5 ) in order to locate the length of the portion of the second section 212 extending out of the receiving groove 1 (i.e., the exposed section 214). For example, during the assembly of the gap adjustment member 2, the length of the exposed section 214 can be controlled by ensuring that the recessed portion 2151 is not rotated out of the anti-drop structure 3 to complete quick assembly.
