Description

Technical Field

[0001] This application relates to the technical field of refrigeration equipment, and in particular to a refrigeration equipment having a door. Background Technology

[0002] In refrigerator and freezer door structures, foamed steel doors are widely used due to their low cost, high strength, and good shape flexibility. A typical door structure consists of a metal door shell, plastic door end caps, an inner liner, and a foamed insulation layer. The door shell, door end caps, and inner liner work together to form a closed cavity, into which polyurethane foam is injected. After curing, it forms a composite layer that combines strength and thermal insulation. To ensure that low-viscosity air can escape smoothly during the foaming process, while preventing high-viscosity liquid foam from overflowing, the industry standard practice is to attach breathable sponge strips to the joint between the door shell and the door end cap.

[0003] However, the aforementioned structure revealed significant drawbacks in actual mass production. First, while the sponge strips could solve the problem of foam overflow, they couldn't overcome the risk of the end cap detaching under stress during transfer, flipping, and foam expansion. To prevent displacement, workers had to manually apply additional tape for mechanical reinforcement at the connection between the door shell and the end cap, increasing the operational steps. Second, the tape was a disposable material, increasing material costs and requiring subsequent removal and cleaning, thus reducing production efficiency. Furthermore, residual tape residue could contaminate the door shell surface. Utility Model Content

[0004] This application provides a refrigeration device that can solve the technical problems of complicated door assembly processes and high material costs.

[0005] This application provides a refrigeration device, comprising:

[0006] The door body has a U-shaped groove on one side for the user to grip, the U-shaped groove extending along the Y direction and opening towards the X direction. The door body includes:

[0007] The door end cover has a first slot at one end with a U-shaped groove, the depth of which extends along the Y direction; the door end cover also has a second slot, the depth of which extends along the Z direction and the opening of which extends along the X direction.

[0008] The door shell is provided with a first insert plate that protrudes along the Y direction and is engaged with a first slot; the door shell is also provided with a second insert plate that protrudes along the Z direction and is engaged with a second slot; wherein, as it approaches the first insert plate, the protrusion height of the second insert plate gradually decreases.

[0009] The refrigeration equipment provided in this application replaces the breathable sponge strips and fixing tape with a self-interlocking structure between the door shell and the door end cover. This allows the exhaust and overflow prevention functions to be directly handled by the mating gaps between the first insert plate and the first slot, and between the second insert plate and the second slot, eliminating the need for any additional auxiliary materials. The insert plates and slots interlock to form a continuous, tortuous sealing path, allowing low-viscosity air to escape smoothly along the micro-gap, while high-viscosity liquid foam material is blocked by multiple bends, achieving the effect of allowing air to pass through but preventing overflow. Once the insert plates are inserted into the slots, they lock together in three dimensions, immediately providing reliable relative positional constraint between the door shell and the door end cover. Regardless of transfer, flipping, or foam expansion, the end cover will not loosen or fall off. Therefore, the production process completely eliminates the cutting, pasting, and pressing processes of the sponge strips, as well as the manual reinforcement of the tape and the subsequent cleaning of residual adhesive, greatly simplifying the workflow and eliminating the risk of contamination on the door surface.

[0010] Furthermore, addressing the issue of interference and difficulty in closing the door shell and end cap insertion paths after eliminating the sponge strip and tape, this application designs the section of the second insert plate near the first insert plate as a gradually lowering avoidance bevel, naturally creating clearance space. During assembly, the first insert plate is first inserted obliquely into the first slot, utilizing the elasticity of the thin metal wall to smoothly position the first end; then, using the first end as a rotation fulcrum, the second end naturally swings down, pushes horizontally, and lifts up, allowing the second insert plate to slide along the avoidance bevel and enter the second slot without obstruction, completing the first-hook-then-clasp rotational closing action. This avoidance feature eliminates the need for tooling assistance during assembly and prevents surface scratches, retaining the simplicity advantages of eliminating sponge and tape while ensuring that the door shell and end cap can be quickly, accurately, and reliably assembled into a stable cavity, laying a good foundation for subsequent foaming.

[0011] In one possible design, the second insert plate has a stress relief groove.

[0012] The above technical solution has the following advantages or beneficial effects: The second insert plate has a stress-relieving groove, dividing the entire second insert plate into independently movable elastic strips. During assembly, if momentary interference occurs due to angular deviation, the elastic strips can naturally retract inward, allowing for additional passage; once the interference point is crossed, the elastic strips immediately spring back to their original position, re-attaching tightly to the second slot wall. This self-deformation capability eliminates the risk of rigid collisions, ensuring that the rotational action of first hooking and then snapping remains smooth, without the need for tooling or external force correction. This protects the second insert plate itself from damage and ensures that the door end cover is assembled in one go, maintaining the simplicity and reliability of the sponge-free and tape-free solution.

[0013] In one possible design, the protrusion height of the second insert plate gradually changes linearly within a range of 53mm to 110mm from the edge of the side with the first insert plate on the door shell.

[0014] The above technical solution has the following advantages or beneficial effects: it provides a specific design scheme, which facilitates the processing and manufacturing of the door.

[0015] In one possible design, the second insert protrudes 8 mm beyond a distance of 110 mm from the edge of the first insert on the door shell.

[0016] The above technical solution has the following advantages or beneficial effects: it provides a specific design scheme, which facilitates the processing and manufacturing of the door.

[0017] In one possible design, the second insert protrudes 3mm within a 53mm radius of the edge of the side with the first insert on the door shell.

[0018] The above technical solution has the following advantages or beneficial effects: it provides a specific design scheme, which facilitates the processing and manufacturing of the door.

[0019] In one possible design, the door end cover is also provided with an abutment plate protruding along the Y direction, which abuts against the inner shell wall of the door.

[0020] The above technical solution has the following advantages or beneficial effects: the abutment plate protrudes along the Y direction and presses against the inner wall of the door shell, providing an additional support point for the door end cover. When the foam expands, the door end cover is clamped in both directions, preventing outward expansion or inward shrinkage deformation and keeping the insertion part always tightly fitted. At the same time, the abutment plate locally flattens the door shell, eliminating gaps caused by the rebound of thin walls, making the exhaust and overflow prevention function continuously effective, and the door surface is flat and beautiful, further improving the stability and appearance quality of the sponge-free and tape-free solution.

[0021] In one possible design, the abutment plate protrudes 14 mm within 110 mm of the edge of the door end cover on the side with the first slot.

[0022] The above technical solution has the following advantages or beneficial effects: it provides a specific design scheme, which facilitates the processing and manufacturing of the door end cover.

[0023] In one possible design, the abutment plate protrudes 8 mm beyond a range of 110 mm from the edge of the side with the first slot on the end cap.

[0024] The above technical solution has the following advantages or beneficial effects: it provides a specific design scheme, which facilitates the processing and manufacturing of the door end cover.

[0025] In one possible design, the overall outline of the first slot is U-shaped.

[0026] The above technical solution has the following advantages or beneficial effects: the overall outline of the first slot is U-shaped, that is, the overall outline of the first insert plate is also U-shaped, so that an effective seal can be formed at the U-shaped groove of the door body to avoid material leakage.

[0027] In one possible design, a guide rib is provided in the second slot.

[0028] The above technical solution has the following advantages or beneficial effects: the second slot is provided with guide ribs, which facilitates the insertion of the second insert plate and further facilitates the assembly of the door shell and the door end cover. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of this application, it should be understood that the terms "inner," "outer," "upper," "bottom," "front," and "rear," etc., indicate the orientation or positional relationship (if any) based on the appendix. Figure 1 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0053] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same component or part. For the same part in the embodiments of this application, the reference numerals may only be used to mark one part or component as an example. It should be understood that the reference numerals are also applicable to other identical parts or components.

[0054] Refrigerators and freezers, as core equipment for modern food preservation, are generally composed of four main modules: the cabinet, the refrigeration system, the electronic control system, and the door. The cabinet typically includes an outer shell, an inner liner, and an insulation layer in between. The refrigeration system integrates the compressor, condenser, evaporator, and throttling element to form a continuous refrigerant cycle. The electronic control system uses sensors and a main control board to precisely regulate temperature and humidity. The door not only provides access but also serves multiple functions, including insulation, sealing, and aesthetics, making it a crucial element for overall energy efficiency and user experience.

[0055] In refrigerator and freezer door structures, foamed steel doors are widely used due to their low cost, high strength, and good shape flexibility. A typical door structure consists of a metal door shell, plastic door end caps, an inner liner, and a foamed insulation layer. For ease of understanding, the door structure in this related technology is described in detail below with reference to the accompanying drawings.

[0056] Figure 1 This is a schematic diagram of a 'door' in related technologies. Figure 2 yes Figure 1 Exploded view of the lower middle door end cover 11' and door shell 12'. Figure 3 yes Figure 2 Enlarged view of point A in the middle.

[0057] like Figures 1-3 As shown, in related technologies, the door body 10' includes a door end cap 11', a door shell 12', and an inner liner 15'. The door shell 12' and the door end cap 11' are interlocked to form a closed cavity with the inner liner 15'. Polyurethane foam is injected into the cavity, and after curing, it forms a composite layer with both strength and thermal insulation properties. To ensure that low-viscosity air can be smoothly discharged during the foaming process while preventing the high-viscosity liquid foam from overflowing, the industry standard practice is to attach a breathable sponge strip 14' to the interlocking gap between the door shell 12' and the door end cap 11'. This sponge strip 14' has both breathable and sealing functions and is considered a key component for balancing airflow and spill prevention.

[0058] However, the aforementioned structure has revealed significant shortcomings in actual mass production. First, the sponge strip 14' can only solve the problem of foam overflow, but cannot overcome the risk of the door end cover 11' falling off under stress during transfer, flipping, and foam expansion. To prevent the door end cover 11' from shifting, workers must manually apply additional tape 13' at the connection between the door shell 12' and the door end cover 11' for mechanical reinforcement, which increases the number of steps. Second, the tape 13' is a disposable auxiliary material, which increases material costs and brings subsequent removal and cleaning processes, reducing production efficiency. In addition, residual adhesive residue from the tape 13' may also contaminate the surface of the door shell 12'. Therefore, the existing dual auxiliary material model of sponge strip 14' and tape 13' is cumbersome and costly, and has become a bottleneck for the production and quality improvement of the steel plate foam door body 10'.

[0059] In view of this, in order to solve the above-mentioned technical problems, this application provides a refrigeration device. The door of this refrigeration device replaces the breathable sponge strip and fixing tape with a self-interlocking structure between the door shell and the door end cover. This allows the exhaust and overflow prevention functions to be directly handled by the mating gaps between the first insert plate and the first slot, and between the second insert plate and the second slot, eliminating the need for any additional auxiliary materials. Once the insert plates are inserted into the slots, they lock together in three dimensions, immediately providing reliable relative positional constraint between the door shell and the door end cover. Regardless of transfer, flipping, or foam expansion, the door end cover will not loosen or fall off.

[0060] To more conveniently illustrate the refrigeration equipment provided in the embodiments of this application, and as an example rather than a limitation, the technical solution of this application will be described in detail below using a refrigerator as an example. Optionally, the refrigeration equipment in this application can also be a freezer, ice maker, or other equipment with a door.

[0061] Figure 4 This is a schematic diagram of a refrigerator provided in an embodiment of this application.

[0062] like Figure 4As shown, this application embodiment first provides a refrigerator, including a door 10 and a cabinet 20. The cabinet 20 is provided with a refrigerator compartment and a freezer compartment. The cabinet 20 is also hinged to the door 10, which is used to seal the refrigerator compartment and the freezer compartment.

[0063] Figure 5 This is a schematic diagram of the door 10 provided in the embodiments of this application. Figure 6 yes Figure 5 Exploded view of door 10 in the diagram. Figure 7 yes Figure 6 Enlarged view of point B in the middle. Figure 8 This is a schematic diagram of the door end cover 11 provided in an embodiment of this application. Figure 9 This is a schematic diagram of the door shell 12 provided in the embodiments of this application. Furthermore, for the convenience of the description of the embodiments below, an XYZ coordinate system is established for the door body 10. Specifically, the length direction of the door body 10 is defined as the Y direction, the width direction of the door body 10 as the X direction, and the thickness direction of the door body 10 as the Z direction. The X, Y, and Z directions are perpendicular to each other.

[0064] like Figures 5-9 As shown in the figure, the door body 10 provided in this application embodiment includes a door end cover 11, a door shell 12, and an inner liner. It should be noted that since the technical solution of this application is aimed at the improvement of the door end cover 11 and the door shell 12, the inner liner is omitted in the figure.

[0065] Continue as Figure 5 As shown, one side of the entire door body 10 has a U-shaped groove 13 for the user to hold. The U-shaped groove 13 extends along the Y direction, and the opening of the U-shaped groove 13 faces the X direction. The U-shaped groove 13 extends along the Y direction, which means that both the door end cover 11 and the door shell 12 have U-shaped grooves 13.

[0066] like Figure 7 and Figure 8 As shown, the door end cover 11 has a first slot 111 at one end of the U-shaped groove 13, and the groove depth of the first slot 111 extends along the Y direction. The door end cover 11 also has a second slot 112, the groove depth of the second slot 112 extends along the Z direction, and the opening of the second slot 112 extends along the X direction.

[0067] like Figure 7 and Figure 9 As shown, the door shell 12 is provided with a first insert plate 121 that protrudes along the Y direction and is engaged with the first slot 111. The door shell 12 is also provided with a second insert plate 122 that protrudes along the Z direction and is engaged with the second slot 112.

[0068] After the first insert plate 121 and the second insert plate 122 on the door shell 12 are inserted into the first slot 111 and the second slot 112 on the door end cover 11, they effectively function similarly to the sponge strip 14' in related technologies. The first insert plate 121 and the second insert plate 122 can prevent the internal foam material from overflowing, and the gap between the insert plate and the slot wall allows air to escape smoothly. After the first insert plate 121 and the first slot 111 are inserted, the door shell 12 and the door end cover 11 form a limit in the X and Z directions, while after the second insert plate 122 and the second slot 112 are inserted, the door shell 12 and the door end cover 11 form a limit in the Y direction, which effectively functions similarly to the tape 13' in related technologies. Therefore, in the embodiment of this application, the assembly of the door shell 12 and the door end cover 11 eliminates the need for two auxiliary materials and corresponding processing steps: the breathable sponge strip 14' and the fixing tape 13', thus shortening the assembly process of the door body 10 during manufacturing and reducing material costs.

[0069] However, upon closer observation Figure 7 As shown, although the door body 10 in this embodiment omits the breathable sponge strip 14' and adhesive tape 13', this increases the assembly difficulty between the door shell 12 and the door end cover 11. Whether assembled from the Y direction or the Z direction, interference and obstruction problems will occur. For ease of understanding, this problem will be explained in detail below with reference to the accompanying drawings.

[0070] Figure 10 This is an assembly schematic diagram of an example of the door shell 12 and door end cover 11 in an embodiment of this application. Figure 11 This is an assembly schematic diagram of another example of the door shell 12 and door end cover 11 in the embodiments of this application.

[0071] like Figure 10 As shown, and in combination Figure 7 As shown, assuming the door shell 12 and door end cover 11 are assembled in the Y direction, as follows: Figure 10 The direction indicated by the middle arrow pushes the door end cover 11 from right to left and inserts it into the door shell 12. This will cause a problem: the second insert plate 122 will interfere with the door end cover 11, resulting in assembly failure.

[0072] like Figure 11 As shown, and in combination Figure 7 As shown, assuming the door shell 12 and the door end cover 11 are assembled in the Z direction, as follows: Figure 11 The direction indicated by the middle arrow pushes the door end cover 11 from bottom to top and inserts it into the door shell 12. This will cause another problem: the first insert plate 121 will interfere with the door end cover 11, resulting in assembly failure.

[0073] Therefore, in order to solve the problem that the door shell 12 and the door end cover 11 cannot be assembled, the second insert plate 122 has been further improved in this embodiment of the application: such as Figure 7As shown, as the second insert plate 122 approaches the first insert plate 121, its protrusion height gradually decreases. This creates a clearance space near the first insert plate 121, allowing the door shell 12 and door end cover 11 to be assembled by first inserting the first insert plate 121 and then inserting the second insert plate 122. For ease of understanding, the assembly process will be described in detail below with reference to the accompanying drawings.

[0074] Figure 12 This is an assembly schematic diagram of another example of the door shell 12 and door end cover 11 in this application embodiment. Figure 12 (a) is a schematic diagram of the initial assembly of the door shell 12 and the door end cover 11; Figure 12 (a) is a schematic diagram of the door shell 12 and door end cover 11 at the end of assembly.

[0075] For ease of description, the end of the door end cover 11 closest to the U-shaped groove 13 is defined as the first end 115, and the end furthest from the U-shaped groove 13 is defined as the second end 116. For example... Figure 12 As shown in (a) and in combination Figure 7 As shown, when assembling the door shell 12 and the door end cover 11, the door end cover 11 is first tilted, and its first end 115 contacts the door shell 12 first, so that the first insert plate 121 is inserted into the first slot 111. It should be noted that since the door shell 12 is usually a thin-walled metal structure, it has a certain elastic deformation capability, so it is possible to insert the first insert plate 121 into the first slot 111 in an tilted manner. Figure 12 As shown in (b) in the figure, and in combination with Figure 7 As shown, with the first end 115 as the fulcrum, the second end 116 moves closer to the door shell 12. It should be noted that in this step, because the protrusion height of the second insert plate 122 near the first end 115 (or the first insert plate 121) is reduced, the second insert plate 122 provides clearance space for the door end cover 11, making the action of "using the first end 115 as the fulcrum and the second end 116 moving closer to the door shell 12" feasible. Continuing as... Figure 12 As shown in (b), after the second end 116 approaches the door shell 12, it uses the first end 115 as a fulcrum and twists the second end 116 in the direction indicated by the arrow in the figure, first down, then left, then up, so as to insert the second insert plate 122 into the second slot 112, and finally complete the assembly of the door shell 12 and the door end cover 11.

[0076] As can be seen from the above description of the assembly process, since the protrusion height of the second insert plate 122 near the first insert plate 121 gradually decreases, the second insert plate 122 forms a certain clearance space near the first insert plate 121, which can facilitate the assembly of the door end cover 11 and the door shell 12.

[0077] In summary, the refrigerator provided in this application replaces the breathable sponge strip 14' and fixing tape 13' with the door shell 12 and door end cover 11's own interlocking structure. This allows the exhaust and overflow prevention functions to be directly handled by the fitting gaps between the first insert plate 121 and the first slot 111, and between the second insert plate 122 and the second slot 112, without the need for any additional auxiliary materials. The insert plate and slot form a continuous and tortuous sealing path while interlocking with each other. Low-viscosity air can be smoothly discharged along the micro-gap, while high-viscosity liquid foam material is blocked by multiple bends, achieving the effect of only allowing air to pass through without overflowing. After the insert plate is inserted into the slot, it locks itself in the three-dimensional direction, and the door shell 12 and door end cover 11 immediately obtain reliable relative position constraints. No matter if it is transferred, flipped, or expanded by foaming, the door end cover 11 will not loosen or fall off. As a result, the production site completely eliminates the cutting, pasting, and pressing processes of the sponge strip 14', as well as the manual reinforcement of the tape 13' and the subsequent cleaning of residual adhesive. The operation process is greatly simplified, and the risk of surface contamination of the door body 10 is reduced to zero.

[0078] Furthermore, addressing the issue of interference and difficulty in closing between the door shell 12 and the door end cover 11 after the removal of the sponge strip 14' and tape 13', this application designs a gradually lowering avoidance bevel on the section of the second insert plate 122 adjacent to the first insert plate 121, naturally creating clearance space. During assembly, the first insert plate 121 is first inserted obliquely into the first slot 111, utilizing the elasticity of the thin metal wall to smoothly position the first end 115; then, using the first end 115 as a rotation fulcrum, the second end 116 swings down, pushes horizontally, and lifts up, allowing the second insert plate 122 to slide along the avoidance bevel and enter the second slot 112 without obstruction, completing the rotational closing action of first hooking and then snapping. This avoidance feature eliminates the need for tooling assistance during assembly and prevents surface scratches, retaining the simplicity advantages of eliminating sponge and tape while ensuring that the door shell 12 and the door end cover 11 can be quickly, accurately, and reliably assembled into a stable cavity, laying a good foundation for subsequent foaming.

[0079] like Figure 9 As shown, in some embodiments, the second insert plate 122 has a stress relief groove 123.

[0080] In this embodiment, the second insert plate 122 is provided with a stress relief groove 123, dividing the entire second insert plate 122 into independently micro-moving elastic strips. During assembly, if momentary interference occurs due to angular deviation, the elastic strips can retract inward to allow for extra passage; once the interference point is crossed, the elastic strips immediately spring back to their original position and re-adhere to the wall of the second slot 112. This self-deformation capability eliminates the risk of rigid collisions, ensuring that the rotational action of first hanging and then fastening remains smooth, without the need for tooling or external force correction. This protects the second insert plate 122 itself from damage and ensures that the door end cover 11 is assembled in one go, maintaining the simplicity and reliability of the sponge-free and tape-free solution.

[0081] Figure 13 yes Figure 9 Enlarged view of point C in the middle.

[0082] like Figure 13 As shown, in some embodiments, the protrusion height of the second insert plate 122 varies linearly within a range of 53mm to 110mm from the edge of the side with the first insert plate 121 on the door housing 12.

[0083] in, Figure 13 The size of region a is 53mm, the size of region b is 57mm, and the sum of the sizes of regions a and b is 110mm.

[0084] In this embodiment, the range of 53mm to 110mm from the edge of the first insert plate 121 on the door shell 12 can be understood as... Figure 13 In region b, the protrusion height d2 of the second insert plate 122 in region b exhibits a linear gradient.

[0085] like Figure 13 As shown, in some embodiments, the protrusion height of the second insert plate 122 is 8 mm, outside the range of 110 mm from the edge of the first insert plate 121 on the door housing 12.

[0086] In this embodiment, the area outside the range of 110mm from the edge of the first insert plate 121 on the side of the door shell 12 can be understood as... Figure 13 The second insert plate 122, excluding areas a and b, has a protrusion height d1 of 8mm.

[0087] like Figure 13 As shown, in some embodiments, the protrusion height of the second insert plate 122 is 3mm within a range of 53mm from the edge of the side with the first insert plate 121 on the door housing 12.

[0088] In this embodiment, within a range of 53mm from the edge of the side with the first insert plate 121 on the door shell 12, it can be understood as Figure 13 In region a, the protrusion height d3 of the second insert plate 122 in region a is 3mm.

[0089] Figure 14 This is a schematic diagram of the door end cover 11 provided in an embodiment of this application.

[0090] like Figure 14 As shown, in some embodiments, the door end cover 11 is also provided with an abutment plate 113 protruding in the Y direction, and the abutment plate 113 abuts against the inner shell wall of the door shell 12.

[0091] In this embodiment, the abutment plate 113 protrudes along the Y direction and presses against the inner wall of the door shell 12, providing an additional support point for the door end cover 11. When the foam expands, the door end cover 11 is clamped in both directions, preventing outward expansion or inward contraction deformation and keeping the insertion part always tightly fitted. At the same time, the abutment plate 113 partially flattens the door shell 12, eliminating gaps caused by thin-walled rebound, making the exhaust and anti-overflow function continuously effective, and the surface of the door body 10 is flat and beautiful, further improving the stability and appearance quality of the sponge-free and tape-free solution.

[0092] Figure 15 yes Figure 14 Enlarged view of point D in the middle.

[0093] like Figure 15 As shown, in some embodiments, the protrusion height of the abutment plate 113 is 14 mm within a range of 110 mm from the edge of the side with the first slot 111 on the door end cover 11.

[0094] in, Figure 15 The size of region c is 110mm.

[0095] In this embodiment, within a range of 110mm from the edge of the side with the first slot 111 on the door end cover 11, it can be understood as Figure 15 In region c, the protrusion height d4 of the abutment plate 113 in region c is 14mm. As mentioned earlier, in order to achieve the assembly of the door end cover 11 and the door shell 12, the protrusion height of the second insert plate 122 in regions a and b is reduced to form a clearance space. However, this increases or decreases the risk of material spillage at this location. To solve this problem, in this embodiment, the protrusion height d4 of the abutment plate 113 in region c is designed to be 14mm, which compensates for the lack of the second insert plate 122 at this location, thereby reducing the risk of material spillage.

[0096] like Figure 15 As shown, in some embodiments, the protrusion height of the abutment plate 113 is 8 mm, outside the range of 110 mm from the edge of the side with the first slot 111 on the door end cover 11.

[0097] In this embodiment, the area outside the range of 110mm from the edge of the side with the first slot 111 on the door end cover 11 can be understood as... Figure 15 The abutment plate 113, excluding area c, has a protrusion height d5 of 8mm.

[0098] In some embodiments, the overall outline of the first slot 111 is U-shaped.

[0099] In this embodiment, the overall outline of the first slot 111 is U-shaped, that is, the overall outline of the first insert plate 121 is also U-shaped, so that an effective seal can be formed at the U-shaped groove 13 of the door body 10 to avoid material leakage.

[0100] like Figure 15 As shown, in some embodiments, a guide rib 114 is provided in the second slot 112.

[0101] In this embodiment, a guide rib 114 is provided in the second slot 112 to facilitate the insertion of the second insert plate 122, and further facilitate the assembly of the door shell 12 and the door end cover 11.

[0102] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
