Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of household appliances, and more particularly to a refrigeration appliance. Background Art

[0002] In the design of refrigeration appliances, the rational utilization and partitioning of storage space have always been an important consideration. Traditional refrigeration appliances, such as refrigerators or freezers, often use a beam structure to divide the storage space into two independent regions, either left and right or up and down.

[0003] Taking a vertical beam that extends in the height direction to divide the storage space left and right as an example, in the prior art, the lower end of the vertical beam is usually fixed to the lower edge of the box body (for example, the inner liner) by screws, while the upper end is only supported by a support pin in a recess on the top wall of the inner liner. This structure lacks sufficient fixing and limiting capabilities. During the subsequent assembly process on the production line, since the wall of the inner liner is very thin and easily deformed, the support pin of the beam easily disengages from the recess on the top wall of the inner liner. This not only affects the assembly efficiency but also may have an adverse impact on the overall structure and performance of the refrigerator. Summary of the Utility Model

[0004] An object of the embodiments of the present utility model is to provide an improved refrigeration appliance.

[0005] Therefore, the embodiments of the present utility model provide a refrigeration appliance, including a box body that defines a storage space open forward, the box body having opposite first and second walls. The refrigeration appliance further includes: a beam having opposite first and second ends along an extending direction, the first end being mounted on the first wall and the second end being mounted on the second wall; a first positioning structure for restricting relative movement between the first end and the first wall in a first plane, a main plane of the first wall facing the first end defining the first plane; a second positioning structure including a first fixing portion and a first mating portion, the first fixing portion being provided on one of the first end and the first wall, and the first mating portion being provided on the other of the first end and the first wall; the first mating portion being configured to mate with the first fixing portion outside the first plane to restrict relative movement between the first end and the first wall in the extending direction of the beam.

[0006] Compared with the existing beam that is positioned only by a single positioning structure and the box body at the end, resulting in poor connection reliability, the embodiments of the present application set two sets of positioning structures, namely the first positioning structure and the second positioning structure, at the corresponding positions of the beam and the box body to achieve all-round restriction of the movement of the beam relative to the box body, more effectively fixing the beam to the box body and preventing the beam from falling off during the assembly process. Specifically, the first positioning structure and the second positioning structure respectively position the relative positions of the first wall and the first end from different positions and directions, improving the connection reliability between the beam and the box body.

[0007] Optionally, the first positioning structure includes a first positioning member and a second mating portion respectively disposed at the first end and the first wall, and the second positioning structure is configured to limit the first wall away from the first end to prevent the first positioning member from disengaging from the second mating portion. Thus, the first positioning structure and the second positioning structure cooperate with each other, and the limiting effect of the second positioning structure on the first wall and the first end avoids the failure of the first positioning structure.

[0008] Optionally, the first fixing portion and the first mating portion are in shape fit to limit the relative movement between the first end and the first wall in the extending direction of the beam.

[0009] Optionally, the second positioning structure is closer to the opening of the box body than the first positioning structure. Thus, the cooperation between the first positioning structure and the second positioning structure can increase the stability of the connection between the beam and the box body. Further, the second positioning structure is located in front of the first positioning structure, which is beneficial to preventing the first end of the beam from protruding forward out of the box body.

[0010] Optionally, at least a part of the projection of the second positioning structure in the depth direction of the refrigeration appliance overlaps with the first positioning structure. Thus, the second positioning structure can pull the wall (i.e., the first wall) of the box body where the first positioning structure is located in the height direction of the refrigeration appliance, reducing the possibility of the beam detaching from the box body.

[0011] Optionally, the first fixing portion includes a hook portion extending rearward from the first end, and the first mating portion includes a receiving groove disposed on the first wall, and the receiving groove opens forward to receive the hook portion. Thus, the hook portion can hook the wall forming the receiving groove to enhance the connection stability between the beam and the box body.

[0012] Optionally, the edge of the first wall is turned outward to form a first flanging, the receiving groove is disposed on the first flanging, the beam includes an extending portion extending outward from the first end, the extending portion is located in front of the first flanging, and the hook portion is disposed on a side of the extending portion facing the first flanging. Thus, the cooperation position of the first fixing portion and the first mating portion does not occupy the space inside the box body and the beam itself, reducing both the occupied storage space and the occupied heat insulation space, making full use of the idle position inside the refrigeration appliance and improving the space utilization rate inside the refrigeration appliance.

[0013] Optionally, in the depth direction of the refrigeration appliance, the first positioning structure is located behind the second positioning structure. Thus, through the cooperation of the first positioning structure and the second positioning structure, one in front and the other behind, it can effectively prevent the beam and the box body from accidentally separating during subsequent assembly.

[0014] Optionally, along the extending direction of the beam, the second positioning structure is further away from the second end than the first positioning structure. Thus, the second positioning structure can limit the movement of the first wall away from the beam. Further, the first positioning structure and the second positioning structure are not at the same height, which is conducive to maximizing the space utilization rate of the box body in the depth direction and avoiding occupying the storage space.

[0015] Optionally, the beam includes a front cover and a rear cover, the direction from the front cover to the rear cover is perpendicular to the direction from the first wall to the second wall, and the first positioning structure includes: a first positioning portion provided at the end of the front cover facing the first wall; a second positioning portion provided at the end of the rear cover facing the first wall; and a second mating portion provided on the first wall, and the second mating portion is used to cooperate with the first positioning portion and the second positioning portion simultaneously to limit the relative movement of the first end and the first wall in the first plane. Thus, the three-way positioning of the front cover, the rear cover and the box body is realized through the first mating portion and the positioning portions provided on both the front cover and the rear cover, making the assembly connection between the beam and the first wall more stable and reliable, which is conducive to increasing the strength of the system formed by the box body and the beam.

[0016] Optionally, the surface of the first positioning portion facing the second positioning portion is in virtual contact with the surface of the second positioning portion facing the first positioning portion. Thus, on the one hand, there is no excessive gap between the first positioning portion and the second positioning portion, avoiding unexpected relative movement between the front cover and the rear cover; on the other hand, there is no mutual acting force between the first positioning portion and the second positioning portion, which can prevent the first positioning portion from being continuously squeezed on the first mating portion due to the outward acting force exerted by the other party and being damaged.

[0017] Optionally, the surface of the first positioning portion facing the second positioning portion abuts against the surface of the second positioning portion facing the first positioning portion. Thus, relative displacement between the front cover and the rear cover is avoided, and a tight fit of the three parts of the front cover, the rear cover and the box body is achieved.

[0018] Optionally, the front cover and the rear cover are used to form a modular structure, and the modular structure is integrally connected to the box body. Among them, the second positioning portion cooperates with the second mating portion prior to the first positioning portion, and a guiding structure is provided on a side of the first positioning portion facing away from the second positioning portion, and the guiding structure is used to guide the assembly of the beam and the box body. During assembly, the rear cover first enters the box body and is positioned at the second mating portion. During this process, the first wall will be pushed up by the second positioning portion and slightly deformed, so that the distance between the receiving groove and the hook portion on the first wall becomes slightly larger. Through the design of the guiding structure, when the first positioning portion of the front cover enters the second mating portion, the first wall can fall slightly due to the arrangement of the guiding structure, so that the hook portion can hook the receiving groove more smoothly. Thus, the first positioning structure and the second positioning structure play a positioning role simultaneously when the beam is assembled in place in the box body, which can reduce the assembly difficulty of the beam and the box body and ensure the safe and reliable installation of the beam to the box body.

[0019] Optionally, the guiding structure includes an inclined portion, and the inclined portion extends obliquely from the end face of the first positioning portion facing the first plane. Thus, the inclined end face plays a guiding role to guide the assembly and positioning of the first end and the box body. Further, the formation process of the inclined portion is relatively simple, for example, it is formed by cutting, which is beneficial to simplifying the production process.

[0020] Optionally, the first positioning portion includes a first bump, which extends away from the front cover from the end cover of the front cover facing the first wall. Thus, the first positioning portion is provided on the front cover with a relatively simple processing technology, and the manufacturing cost is low.

[0021] Optionally, the second positioning portion includes a second bump, which extends away from the rear cover from the end cover of the rear cover facing the first wall. Thus, the second positioning portion is provided on the rear cover with a relatively simple processing technology, and the manufacturing cost is low.

[0022] Optionally, the second mating portion includes a first groove that is recessed from the first wall in a direction away from the second wall. Thus, the first groove can be used to receive the first positioning portion and / or the second positioning portion to achieve a reliable connection between the beam and the first wall.

[0023] Optionally, the front cover and the rear cover jointly enclose a heat insulation space, and the heat insulation space is used to fill heat insulation materials. Thus, the beam is also formed with a heat insulation layer, which is beneficial to improving the heat insulation performance of the refrigeration appliance.

[0024] Optionally, the refrigeration appliance further includes: a first mounting portion disposed around the front cover and extending from the edge of the front cover toward the rear cover; a second mounting portion disposed around the rear cover and extending from the edge of the rear cover toward the front cover; wherein, one of the second mounting portion and the first mounting portion overlaps the other on the outside, and / or, the first mounting portion and the second mounting portion form a multi-folded contact structure. Thus, through the cooperation of the first mounting portion and the second mounting portion, the sealing effect of the heat insulation space inside the beam can be improved, and leakage of the internal heat insulation material can be avoided.

Detailed implementation mode

[0036] As described in the background art, the connection and positioning between the existing beam and the cabinet are only achieved by the cooperation of the support pins on the beam and the recesses on the cabinet. During the subsequent assembly process on the production line, since the walls of the cabinet are very thin and prone to deformation, the support pins of the beam are easily disengaged from the recesses on the cabinet wall, affecting the assembly efficiency.

[0037] In addition, the existing beam is usually formed by splicing a front cover and a rear cover. The connection between the front cover and the rear cover and between the rear cover and the inner liner is only bonded by a foaming layer. This connection method lacks a direct fixed connection, resulting in relatively weak reliability of the overall positioning and fixed connection. Although the foaming layer has a certain adhesive force, it is easily loosened or detached during long - term use or when subjected to external impacts.

[0038] To solve at least one of the above - mentioned technical problems, an embodiment of the present utility model provides a refrigeration appliance, including a cabinet, the cabinet defining a storage space opening forward, the cabinet having opposite first and second walls, the refrigeration appliance further including: a beam having opposite first and second ends along an extending direction, the first end being mounted on the first wall and the second end being mounted on the second wall; a first positioning structure for restricting relative movement between the first end and the first wall in a first plane, a main plane of the first wall facing the first end defining the first plane; a second positioning structure including a first fixing portion and a first mating portion, the first fixing portion being provided on one of the first end and the first wall, and the first mating portion being provided on the other of the first end and the first wall; the first mating portion being used to cooperate with the first fixing portion outside the first plane to restrict relative movement between the first end and the first wall in the extending direction of the beam.

[0039] The embodiment of the present application sets two sets of positioning structures, namely the first positioning structure and the second positioning structure, at the corresponding positions of the beam and the box body, so as to achieve all-round restriction on the movement of the beam relative to the box body, more effectively fix the beam to the box body, and prevent the beam from falling off during the assembly process. Specifically, the first positioning structure and the second positioning structure respectively locate the relative positions of the first wall and the first end from different positions and directions, thereby improving the connection reliability of the beam and the box body.

[0040] 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.

[0041] Figure 1 It is a schematic diagram of a refrigeration appliance 100 according to an embodiment of the present utility model.

[0042] refer to Figure 1 The refrigeration appliance 100 may be, for example, a refrigerator, a freezer, etc. Taking a refrigerator as an example, the basic structure of a modern refrigerator generally includes a door 101 and a housing 1. The housing 1 is the main structure of the refrigerator, which defines a storage space 10 that is open to the front (towards the user). The storage space 10 can be used to store various foods or drinks that need to be refrigerated or cooled, so its design and layout are crucial to improving the efficiency and convenience of the refrigerator. The door 101 is arranged in front of the housing 1 to open or close the housing 1.

[0043] For ease of description, in this embodiment, the width direction of the refrigeration appliance 100 is recorded as the x direction, the depth 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 y direction and the opposite direction when the door 101 closes the storage space 10, 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. In this embodiment, the up-down direction refers to the z direction and the opposite direction.

[0044] refer to Figure 1 , the refrigeration appliance 100 described in this embodiment may be, for example, a refrigerator.

[0045] In some embodiments, the refrigerator may include a housing 1, wherein the housing 1 defines a storage space 10 that is open forward (e.g., in the y direction). The storage space 10 may be used to store daily items to be refrigerated or cooled, such as food or drinks. Further, the housing 1 may be, for example, an inner container of a refrigerator or other refrigeration appliance 100. The housing 1 may be covered with a shell 102 for protection.

[0046] In some embodiments, the refrigeration appliance 100 may include two boxes 1 arranged vertically in the z direction to form storage spaces 10 at different temperatures, such as a refrigerating compartment and a freezing compartment respectively. Further, the designs of the upper and lower boxes 1 in terms of structure may be the same. Therefore, hereinafter, mainly Figure 1 the box 1 located at the lower part will be taken as an example for exemplary display and description.

[0047] Further, referring to Figure 2 , along the z direction, the box 1 has opposite first wall 11 and second wall 12. Among them, the first wall 11 may be, for example, the top wall of the box 1, that is, the wall on one side facing the z direction. The second wall 12 may be, for example, the bottom wall of the box 1, that is, the wall on the side opposite to the z direction.

[0048] Further, referring to Figures 1 to 5 , the refrigeration appliance 100 may further include: a beam 2, the beam 2 having opposite first end 21 and second end 22 along the extending direction, the first end 21 being mounted on the first wall 11, and the second end 22 being mounted on the second wall 12; a first positioning structure 3 for restricting the relative movement between the first end 21 and the first wall 11 in a first plane P1 (such as Figure 3 ); the main plane of the first wall 11 facing the first end 21 defines the first plane P1; a second positioning structure 4 including a first fixing portion 41 and a first mating portion 42, the first fixing portion 41 being provided on one of the first end 21 and the first wall 11, and the first mating portion 42 being provided on the other of the first end 21 and the first wall 11; the first mating portion 42 is used to cooperate with the first fixing portion 41 outside the first plane P1 to restrict the relative movement between the first end 21 and the first wall 11 in the extending direction of the beam 2. Thus, by providing two sets of positioning structures, namely the first positioning structure 3 and the second positioning structure 4, at the corresponding positions of the beam 2 and the box 1, the movement of the beam 2 relative to the box 1 is restricted in all directions, and the beam 2 is more effectively fixed to the box 1, avoiding the beam 2 from falling off during the assembly process. Specifically, the first positioning structure 3 and the second positioning structure 4 respectively position the relative positions of the first wall 11 and the first end 21 from different positions and directions, improving the connection reliability between the beam 2 and the box 1.

[0049] Specifically, after the beam 2 and the box 1 are assembled, the extending direction of the beam 2 may be, for example, the z direction. That is, the beam 2 is supported between the first wall 11 and the second wall 12 of the box 1 along the z direction. In this example, the beam 2 extending along the z direction may also be a vertical beam.

[0050] Further, the first end 21 is connected to the first wall 11 through a first positioning structure 3 and a second positioning structure 4. Among them, the main plane of the first wall 11 facing the first end 21 is denoted as the first plane P1. The first plane P1 is perpendicular to the extending direction of the beam 2 (for example, the z direction).

[0051] Further, the first positioning structure 3 is used to limit the relative movement between the first end 21 and the first wall 11 within the first plane P1.

[0052] In some embodiments, referring to Figure 5 , the first positioning structure 3 includes a first positioning member 31 and a second mating portion 32 respectively provided on the first end 21 and the first wall 11. Among them, the first positioning member 31 can be, for example, a protrusion extending from the first end 21 of the beam 2 in the z direction, and the second mating portion 32 can include, for example, a first groove 321 recessed from the first wall 11 in the z direction. During the assembly process, when the protrusion is inserted into the first groove 321, the first positioning member 31 and the second mating portion 32 are mated to form the first positioning structure 3. Further, the shape of the first positioning member 31 (for example, the protrusion) can be adapted to the shape of the second mating portion 32 (for example, the first groove 321). Thus, the cooperation between the second mating portion 32 and the first positioning member 31 can be used to limit the relative movement between the first end 21 and the first wall 11 within the first plane P1.

[0053] In some embodiments, continuing to refer to Figure 5 , the second positioning structure 4 can include a first fixing portion 41 and a first mating portion 42. Different from at least a part of the above-mentioned first positioning member 31 and the second mating portion 32 being mated within the first plane P1, the first fixing portion 41 and the first mating portion 42 are mated outside the first plane P1. That is, the position where the first fixing portion 41 and the first mating portion 42 are mated to position the first end 21 and the first wall 11 is not coplanar with the first plane P1.

[0054] Further, the second positioning structure 4 is used to limit the first wall 11 from moving away from the first end 21 to prevent the first positioning member 31 from disengaging from the second mating portion 32. Specifically, through the cooperation between the first mating portion 42 and the first fixing portion 41, the relative movement between the first end 21 and the first wall 11 in the z direction can be effectively limited. Thus, it is possible to avoid the accidental detachment of the beam 2 during the assembly process (for example, when handling the semi-finished refrigerator with the box body 1 and the beam 2 already in a pre-assembled state), which is beneficial to improving the assembly efficiency.

[0055] Combined with Figure 5, in some embodiments, the second positioning structure 4 is closer to the opening of the box body 1 than the first positioning structure 3, that is, closer to the door 101. Thus, the cooperation between the first positioning structure 3 and the second positioning structure 4 can increase the stability of the connection between the beam 2 and the box body 1. Further, the second positioning structure 4 is located in front of the first positioning structure 3, which is beneficial to prevent the first end 21 of the beam 2 from slipping out of the box body 1 forward.

[0056] In some embodiments, the projection of the second positioning structure 4 in the depth direction of the refrigeration appliance 100 at least partially overlaps with the first positioning structure 3. Thus, the second positioning structure 4 can pull the wall (i.e., the first wall 11) of the box body 1 where the first positioning structure 3 is located along the height direction of the refrigeration appliance 100, reducing the possibility of the beam 2 detaching from the box body 1.

[0057] Further, in combination Figure 5 and Figure 7 , the first fixing portion 41 can be disposed, for example, at the first end 21, and the first mating portion 42 can be disposed, for example, on the first wall 11.

[0058] Specifically, the first fixing portion 41 includes a hook portion 411 extending rearward (e.g., in the opposite direction of the y direction) from the first end 21, and the first mating portion 42 includes a receiving groove 421 disposed on the first wall 11. The receiving groove 421 is open forward to receive the hook portion 411. Thus, the hook portion 411 can hook the wall forming the receiving groove 421 to limit the relative movement between the first wall 11 and the first end 21 in the z direction, enhancing the stability of the connection between the beam 2 and the box body 1.

[0059] Further, the edge of the first wall 11 is turned outward to form a first flanging 111, the receiving groove 421 is disposed on the first flanging 111, and the beam 2 includes an extension portion 412 extending outward from the first end 21. The extension portion 412 is located in front of the first flanging 111, and the hook portion 411 is disposed on the side of the extension portion 412 facing the first flanging 111. Thus, the cooperation position of the first fixing portion 41 and the first mating portion 42 does not occupy the space inside the box body 1 and the beam 2 itself, reducing both the occupied storage space 10 and the occupied heat insulation space 26 of the beam 2 itself, making full use of the idle positions inside the refrigeration appliance 100 and improving the space utilization rate inside the refrigeration appliance 100.

[0060] In some embodiments, the first flanging 111 may be substantially perpendicular to the first plane P1. The receiving groove 421 is open in the y direction, and the hook portion 411 can be inserted into the receiving groove 421 in the opposite direction of the y direction. Further, the surface of the hook portion 411 facing the first end 21 may be in contact with the wall of the first plane P1 of the receiving groove 421. Thus, in the z direction, the hook portion 411 can firmly hook the first flanging 111.

[0061] In a variant, the first fixing portion 41 may also be provided on the first wall 11, for example, and the first mating portion 42 is provided on the first end 21. For example, the first flanging 111 may be provided with a hook projecting forward, and the extending portion 412 of the first end 21 is provided with a second groove opening backward. As the beam 2 is installed into the box body 1, the hook hooks the second groove, realizing the cooperation of the second positioning structure 3.

[0062] In some embodiments, referring to Figures 3 to 5 , a boss 112 protruding upward in the z direction may be formed on the first wall 11 near the opening, and a first groove 321 is further formed to protrude upward on the boss 112. The projection of the boss 112 in the y direction on the first flanging 111 may cover the receiving groove 421. Correspondingly, the portion of the boss 112 located between the first groove 321 and the receiving groove 421 is clamped between the first positioning structure 3 and the second positioning structure 4. Thus, the connection between the first end 21 and the first wall 11 is more reliable and firm.

[0063] In some embodiments, along the depth direction of the refrigeration appliance 100 (for example, the y direction), the first positioning structure 3 is located behind the second positioning structure 4. Thus, through the cooperation of the first positioning structure 3 and the second positioning structure 4, one in front and one behind, it is possible to effectively prevent the beam 2 and the box body 1 from being accidentally separated during subsequent assembly.

[0064] Along the extending direction of the beam 2 (for example, the z direction), the second positioning structure 4 is farther from the second end 22 than the first positioning structure 3. Thus, the second positioning structure 4 can limit the movement of the first wall 11 in the direction away from the beam 2. Further, the first positioning structure 3 and the second positioning structure 4 are not at the same height, which is beneficial to maximizing the space utilization rate of the box body 1 in the depth direction and avoiding occupying the storage space 10.

[0065] In some embodiments, when the beam 2 is vertically installed in place, in the z direction, the second positioning structure 4 is not lower than the first positioning structure 3.

[0066] Further, there may be a non-zero gap between the receiving groove 421 and the first plane P1, and the size of this gap may be substantially equal to the depth of the first groove 321.

[0067] In a specific implementation, referring toFigures 7 to 9 The beam 2 includes a front cover 23 and a rear cover 24. The direction in which the front cover 23 points to the rear cover 24 is perpendicular to the direction in which the first wall 11 points to the second wall 12 (for example, the z direction). In this specific embodiment, the end of the front cover 23 facing the first wall 11 and the end of the rear cover 24 facing the first wall 11 together form the first end 21.

[0068] For example, when the beam 2 is vertically placed as shown in the figure, the front cover 23 and the rear cover 24 are placed front and back along the y direction, and the first wall 11 and the second wall 12 are the top wall and the bottom wall of the box body 1 respectively. Another example is that when the beam 2 is horizontally placed along the x direction, the front cover 23 and the rear cover 24 are placed front and back along the y direction, and the first wall 11 and the second wall 12 are the left and right side walls of the box body 1 respectively. In this example, the beam 2 can also be a cross beam.

[0069] Furthermore, the first positioning structure 3 includes: a first positioning portion 311, which is arranged at the end of the front cover 23 facing the first wall 11; a second positioning portion 312, which is arranged at the end of the rear cover 24 facing the first wall 11; and a second cooperation portion 32, which is arranged on the first wall 11. The second cooperation portion 32 is used to cooperate with the first positioning portion 311 and the second positioning portion 312 simultaneously to limit the relative movement between the first end 21 and the first wall 11 in the first plane P1.

[0070] Thus, through the first cooperation portion 42 and the positioning portions provided on both the front cover and the rear cover, the three-way positioning of the front cover 23, the rear cover 24, and the box body 1 is realized, making the assembly connection between the beam 2 and the first wall 11 more stable and reliable, which is beneficial to increasing the strength of the system formed by the box body 1 and the beam 2.

[0071] In a variant, the first positioning portion 311 and the second positioning portion 312 can also be both arranged on the front cover 23. Thus, first, the stable connection between the front cover 23 and the first wall 11 is realized through the cooperation of the first positioning portion 311, the second positioning portion 312, and the second cooperation portion 32 and the second positioning structure 4, and then the rear cover 24 and the front cover 23 are bonded by heat-insulating materials such as foaming agents, and the stable connection between the whole beam 2 and the first wall 11 can also be realized.

[0072] In some embodiments, continuing to refer to Figure 5 , the surface of the first positioning portion 311 facing the second positioning portion 312 and the surface of the second positioning portion 312 facing the first positioning portion 311 can be in virtual contact. Thus, on the one hand, there is no excessive gap between the first positioning portion 311 and the second positioning portion 312, avoiding unexpected relative movement between the front cover 23 and the rear cover 24; on the other hand, there is no mutual acting force between the first positioning portion 311 and the second positioning portion 312, which can avoid the first positioning portion 311 being continuously squeezed on the first cooperation portion 42 due to the outward acting force exerted by the other party and being damaged.

[0073] In some embodiments, continue to refer to Figure 5 , the surface of the first positioning portion 311 facing the second positioning portion 312 and the surface of the second positioning portion 312 facing the first positioning portion 311 can abut against each other. Thus, relative displacement between the front cover 23 and the rear cover 24 can be avoided, thereby achieving a tight fit among the front cover 23, the rear cover 24 and the box body 1.

[0074] Specifically, the second matching portion 32 may be, for example, a first groove 321, and the size of the first groove 321 may be slightly smaller than the size of the outer contour formed by the first positioning portion 311 and the second positioning portion 312. Thus, the first positioning portion 311 and the second positioning portion 312 require a certain amount of force to fit into the first matching portion 42 (for example, the first groove 321), further improving the reliability of the positioning connection between the three.

[0075] Combination Figures 5 to 9 In some embodiments, the front cover 23 and the rear cover 24 are used to form a modular structure (i.e., the beam 2), and the modular structure is integrally connected to the box body 1, wherein the second positioning portion 312 cooperates with the second matching portion 32 before the first positioning portion 311, and a guide structure 313 is provided on the side of the first positioning portion 311 away from the second positioning portion 312, and the guide structure 313 is used to guide the assembly of the beam 2 and the box body 1.

[0076] In a typical application scenario, during assembly, the second end 22 of the beam 2 is first connected to the second wall 12 with the front cover 23 facing forward and the rear cover 24 facing backward. Specifically, the second end 22 and the second wall 12 can be connected by a fixing member 5 (such as a screw), for example. Figure 6 As shown. Further, the beam 2 can rotate backward with the second end 22 as the center so that the first end 21 gradually approaches the first wall 11 until the first end 21 and the first wall 11 are assembled. In this process, the second positioning portion 312 will enter the first matching portion 42 (first groove 321) before the first positioning portion 311, and as the second positioning portion 312 gradually enters the first matching portion 42, the first wall 11 will be lifted up by the second positioning portion 312 and slightly deformed, so that the distance between the receiving groove 421 and the hook portion 411 on the first wall 11 is slightly increased. Through the design of the guide structure 313, when the first positioning portion 311 of the front cover 23 enters the second matching portion 32, the first wall 11 can fall back slightly due to the setting of the guide structure 313, so that the hook portion 411 can hook the receiving groove 421 more smoothly. Therefore, the first positioning structure 3 and the second positioning structure 4 play a positioning role as the beam 2 is assembled into the box body 1, which can reduce the difficulty of assembling the beam 2 and the box body 1 and ensure that the beam 2 is safely and reliably installed in the box body 1.

[0077] Further, the guide structure 313 includes an inclined portion, which is formed by the end face of the first positioning portion 311 extending obliquely toward the first plane P1. Specifically, the end face of the first positioning portion 311 faces backward and is inclined toward the first plane P1 to form the inclined portion. The inclined extended end face plays a guiding role, guiding the first end 21 and the box body 1 to complete assembly and positioning.

[0078] In some embodiments, the inclined portion can be cut directly on the surface of the first positioning portion 311 facing the z direction by a simple cutting process. Therefore, the process for forming the inclined portion is relatively simple, which is conducive to simplifying the production process.

[0079] In some embodiments, the first positioning portion 311 includes a first protrusion extending from the end cover of the front cover 23 toward the first wall 11 in a direction away from the front cover 23. Thus, the first positioning portion 311 is provided on the front cover 23 with a relatively simple processing technology, and the manufacturing cost is low.

[0080] In some embodiments, the second positioning portion 312 includes a second protrusion extending from the end cover of the rear cover 24 toward the first wall 11 in a direction away from the rear cover 24. Thus, the second positioning portion 312 is provided on the rear cover 24 with a relatively simple processing technology, and the manufacturing cost is low.

[0081] In some embodiments, the second matching portion 32 includes a first groove 321 recessed from the first wall 11 toward a direction away from the second wall 12. Thus, the first groove 321 can be used to receive the first positioning portion 311 and / or the second positioning portion 312 to achieve a reliable connection between the beam 2 and the first wall 11.

[0082] Furthermore, the front cover 23 and the rear cover 24 together enclose a heat-insulating space 26, and the heat-insulating space 26 is used to fill a heat-insulating material. Thus, the beam 2 also forms a heat-insulating layer, which is beneficial to improving the heat-insulating performance of the refrigeration appliance 100.

[0083] Furthermore, a through-hole structure 25 is provided on the wall of the beam 2 used to form the first end 21 , and the heat-insulating space 26 can be filled with heat-insulating material through the through-hole structure 25 .

[0084] Furthermore, the heat insulating material may be, for example, a foaming agent. Thus, the foaming agent can also be used to tightly bond the front cover 23 and the rear cover 24 together to improve the overall structural strength of the beam 2.

[0085] Further reference Figure 5 , Figure 8 and Figure 9, the refrigeration appliance 100 further includes: a first mounting portion 231, which is disposed around the front cover 23 and extends from the edge of the front cover 23 towards the rear cover 24; a second mounting portion 241, which is disposed around the rear cover 24 and extends from the edge of the rear cover 24 towards the front cover 23; wherein, one of the second mounting portion 241 and the first mounting portion 231 overlaps the outside of the other. Thus, through the cooperation of the first mounting portion 231 and the second mounting portion 241, the sealing effect of the internal heat insulation space 26 of the beam 2 can be improved, and the leakage of the internal heat insulation material can be avoided.

[0086] In some embodiments, the first mounting portion 231 and the second mounting portion 241 form a multi-folded contact structure. For example, the direction pointing from the inside of the beam 2 (i.e., the heat insulation space 26) to the outside is denoted as the first direction (for example, the z-direction in a Figure 5 perspective). The contact surface of the first mounting portion 231 and the second mounting portion 241 is not a complete plane parallel to the first direction, but is obtained by bending a surface with an overall tendency to be parallel to the first direction at least once in the front-rear direction. Thus, at least one contact surface perpendicular to the first direction is formed along the splicing joint of the front cover 23 and the rear cover 24, which is beneficial to increasing the resistance to the outward leakage of the heat insulation material during the foaming process of the beam 2 and reducing the possibility of the leakage of the foaming material.

[0087] Specifically, in combination with Figure 5 , Figure 8 and Figure 9, the front cover 23 may further include a first main body portion 232, and the first mounting portion 231 is connected to the rear side of the first main body portion 232. Further, along the y direction, the area of the region surrounded by the inner surface of the first main body portion 232 (i.e., the surface facing the heat insulation space 26) is smaller than the area of the region surrounded by the inner surface of the first mounting portion 231. At this time, a first step structure is formed at the connection between the first main body portion 232 and the first mounting portion 231. Similarly, the rear cover 24 may further include a second main body portion 242, and the second mounting portion 241 is connected to the front side of the second main body portion 242. Further, along the y direction, the area of the region surrounded by the outer surface of the second main body portion 242 (i.e., the surface facing away from the heat insulation space 26) is larger than the area of the region surrounded by the outer surface of the second mounting portion 241. At this time, a second step structure is formed at the connection between the second main body portion 242 and the second mounting portion 241. Further, when the first mounting portion 231 and the second mounting portion 241 cooperate, the first mounting portion 231 abuts against the second step structure, the second mounting portion 241 abuts against the first step structure, and the inner surface of the first mounting portion 231 and the outer surface of the second mounting portion 241 are closely attached. In this scenario, a Z-shaped contact surface is formed between the first mounting portion 231 and the second mounting portion 241. Thereby, the sealing effect of the internal space of the beam 2 can be improved, and the leakage of the internal heat insulation material can be avoided.

[0088] In a variation of the above embodiment, the first wall 11 and the second wall 12 may also be, for example, two side walls of the box body 1 opposite to each other in the x direction (i.e., the left and right side walls), and the extending direction of the assembled beam 2 may be, for example, the x direction. In this scenario, the setting positions and cooperation manners of the first positioning structure 3 and the second positioning structure 4 may refer to the foregoing description about Figures 1 to 9 , and will not be elaborated here.
