Description

Technical Field

[0001] This application belongs to the field of refrigeration technology, and in particular relates to a refrigeration device. Background Technology

[0002] The inner liner of refrigeration equipment is generally made of plastic. Because plastic inner liners have low strength, they may become brittle or deform at low or high temperatures. Prolonged use can easily lead to cracking, discoloration, and yellowing. Furthermore, plastic inner liners may absorb food odors, making them difficult to clean after long-term use. They also lack adequate antibacterial properties, making cleaning challenging. Therefore, some refrigeration equipment incorporates a metal inner liner structure to address the problems of cracking and discoloration associated with plastic inner liners over time, optimize the overall antibacterial performance of the refrigeration equipment, and reduce cleaning difficulty.

[0003] In related technologies, partitions mostly use extended injection ports, relying on the significant deformation of the plastic inner liner for installation. However, for refrigeration equipment that uses a metal inner liner, the above-mentioned partition installation method is problematic because the hardness of the metal inner liner is much greater than that of the plastic inner liner, and the deformation of the metal inner liner is far less than that of the plastic inner liner. This results in the partition being prone to shaking after installation, affecting the stability and sealing of the partition. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a refrigeration device that effectively solves the problem that the high hardness of the metal inner liner means that its deformation alone is insufficient to fix the partition, thereby improving the reliability and stability of the partition installation and optimizing the sealing performance of the partition.

[0005] In a first aspect, this application provides a refrigeration device, comprising:

[0006] shell;

[0007] The inner liner is installed inside the outer shell, forming a compartment with one side open. The side wall of the inner liner is a metal plate, and a first foaming cavity is formed between the inner liner and the outer shell.

[0008] A partition is provided in the compartment to divide the compartment into multiple storage spaces and to form a second foaming cavity;

[0009] The injection component is installed on the outside of the side wall of the inner liner. A portion of the injection component extends into the compartment and connects to the partition. The injection component also connects the first foaming chamber and the second foaming chamber.

[0010] An insulation layer is formed in the first foaming cavity and the second foaming cavity.

[0011] According to the refrigeration equipment of this application, the structure design of the partition indirectly installed in the inner liner using the injection molding component, through the solidification of the insulation layer to wrap the injection molding component, makes the injection molding component firmly fixed to the side wall of the inner liner under the anchoring force of the insulation layer. On the basis of the original connection, the bonding force between the injection molding component and the partition is further increased, and the partition installation force is distributed to the entire insulation layer through the injection molding component. This effectively solves the problem that the high hardness of the metal inner liner makes it insufficient to fix the partition by its deformation alone, thereby significantly improving the reliability and stability of the partition installation, and significantly optimizing the sealing performance of the partition, reducing the risk of leakage of the insulation material during the foaming process, thereby maintaining the integrity and insulation effect of the insulation layer. At the same time, it realizes the integrated foaming of the partition and the main structure of the refrigeration equipment, simplifies the production process, and thus improves production efficiency.

[0012] According to one embodiment of this application, the injection component passes through the inner liner and the partition, and the side of the injection component near the compartment is provided with a first snap-fit ​​structure, and the partition is provided with a second snap-fit ​​structure. The first snap-fit ​​structure and the second snap-fit ​​structure engage to clamp the inner liner between the injection component and the partition.

[0013] According to the refrigeration equipment of this application, the injection component is inserted into the inner liner and the partition as described above, and the first and second snap-fit ​​structures are used for snap-fit ​​engagement. The snap-fit ​​structure provides initial installation positioning force, and the insulation material forms secondary reinforcement after curing. The synergistic effect of the two makes the connection between the partition and the inner liner tighter and stronger, reducing the possibility of the partition shaking during use and greatly improving the stability of the partition installation. Since the inner liner is clamped between the injection component and the partition, the installation force is evenly transmitted to the entire inner liner sidewall through the snap-fit ​​position, reducing deformation or cracking of the inner liner caused by local stress concentration, improving structural durability, and further reducing the gap between the injection component, the inner liner and the partition, reducing the risk of insulation material leakage during foaming. In addition, it can also realize the rapid pre-installation of the partition, shorten the assembly time, and the standardized snap-fit ​​interface facilitates automated assembly line operation, reduces manual alignment errors and improves production efficiency.

[0014] According to one embodiment of this application, the first snap-fit ​​structure includes a plurality of snap hooks spaced apart, at least two of which have hooks facing different directions, and the second snap-fit ​​structure includes a plurality of protrusions protruding from the inner wall of the partition.

[0015] According to the refrigeration equipment of this application, by setting up the above-mentioned multiple hooks and multiple bosses, and combining the fact that at least two of the hooks have different hook orientations, the snap-fit ​​between the first snap-fit ​​structure and the second snap-fit ​​structure has multi-directional restriction. When the partition is subjected to external forces in different directions, the hooks with different hook orientations can provide snap-fit ​​forces from different angles, reducing the displacement of the partition in the horizontal, vertical or other directions, greatly enhancing the stability of the snap-fit, and helping the partition to always be firmly fixed on the inner liner. In addition, due to the cantilever structure of the hook itself, the hook has a large deformation capacity. Since there will inevitably be certain dimensional errors during the production process, the hook can accommodate these errors through its own elastic deformation, reducing assembly failures and rework caused by size mismatch, thereby reducing the assembly difficulty of the partition and the injection part, and thus improving the assembly efficiency of the partition and the injection part.

[0016] According to one embodiment of this application, the injection component includes a substrate and a guide structure protruding from the substrate toward the chamber. The substrate is located in the first foaming cavity and abuts against the outer surface of the inner liner. The guide structure passes through the inner liner and the partition, engages with the partition, and forms a feeding channel for connecting the first foaming cavity and the second foaming cavity. The outer surface of the guide structure is sealed to the inner liner and the partition.

[0017] According to the refrigeration equipment of this application, the sealing cooperation between the above-mentioned guide structure and the inner liner and the partition, combined with the contact of the substrate with the outer surface of the inner liner, forms a double sealing barrier, which prevents the insulation material from overflowing from the gaps during the foaming process as much as possible. This effectively alleviates the negative impact of foam material leakage on the internal structure and appearance of the refrigeration equipment, enhances the sealing performance of the entire refrigeration equipment, and maintains the integrity and quality of the insulation layer.

[0018] According to one embodiment of this application, the refrigeration device further includes:

[0019] Fasteners connect the injection unit, the inner liner, and the partition.

[0020] According to the refrigeration equipment of this application, by setting the above-mentioned fasteners, the fasteners directly connect the injection component, the inner liner and the partition into one body to form a mechanical lock. On the basis of the clamping force of the first clamping structure and the second clamping structure, the initial pre-tightening force before foaming is further enhanced. After the insulation material is cured to form an insulation layer, the clamping force, the fastening force and the insulation layer anchoring force work together to lock the inner liner, the injection component and the partition into one body as much as possible, further reducing the misalignment between the injection component, the inner liner and the partition, and maximizing the stability and reliability of the refrigeration equipment structure.

[0021] According to one embodiment of this application, the inner liner is provided with a third snap-fit ​​structure, the third snap-fit ​​structure is distributed at a distance from the injection part, and the partition is provided with a fourth snap-fit ​​structure for snap-fitting with the third snap-fit ​​structure.

[0022] According to the refrigeration equipment of this application, by cooperating with the third snap-fit ​​structure of the inner liner and the fourth snap-fit ​​structure 1511 of the partition, additional fixing points are provided for the partition based on the snap-fit ​​of the injection part and the partition, fixing the partition from multiple directions and positions, providing initial positioning before foaming, minimizing the shaking or displacement of the partition during the foaming process and use, optimizing the foaming effect, and enhancing the stability of the partition installation.

[0023] According to one embodiment of this application, the back wall of the inner liner is a metal plate, and the filling component is installed thereon.

[0024] According to the refrigeration equipment of this application, by adding a material injection component to the back wall of the inner liner as described above, on the one hand, the material injection component on the back wall of the inner liner and the material injection components on the side walls of the inner liner form a multi-point support system, constraining the displacement of the partition from multiple directions. The material injection component on the back wall of the inner liner shares the longitudinal load of the partition, reducing the stress on the material injection components on the side walls, and effectively alleviating loosening or damage caused by excessive local stress. On the other hand, based on the original feeding channels distributed on both sides of the partition, a feeding channel distributed on the back of the partition is added, increasing the feeding path of the partition during the foaming process, reducing defects such as bubbles, voids or uneven thickness caused by poor material flow, so that the insulation material can be evenly distributed inside the partition, thereby forming a continuous, uniform and dense insulation layer in the first foaming cavity and the second foaming cavity, improving the quality of the insulation layer, and thus optimizing the insulation performance of the refrigeration equipment.

[0025] According to one embodiment of this application, the partition includes a connected bottom shell and a top cover, the top cover covering the bottom shell, the top cover having a fifth snap-fit ​​structure, and the bottom shell having a sixth snap-fit ​​structure for snap-fitting with the fifth snap-fit ​​structure.

[0026] According to one embodiment of this application, the inner sidewall of the top cover is provided with a first hook, and at least a portion of the side of the bottom shell is inserted into the first hook.

[0027] According to one embodiment of this application, the inner top wall of the upper cover is provided with a first positioning member, and the inner bottom wall of the bottom shell is provided with a second positioning member for positioning and cooperating with the first positioning member.

[0028] According to one embodiment of this application, the first positioning member and the second positioning member are sleeved together, the first positioning member is provided with a seventh snap-fit ​​structure, and the second positioning member is provided with an eighth snap-fit ​​structure for snap-fitting with the seventh snap-fit ​​structure.

[0029] According to one embodiment of this application, the bottom shell includes a first shell and a second shell covering the first shell, and the top cover includes a first cover and a second cover covering the first cover, wherein the first shell and the first cover are made of plastic, and the second shell and the second cover are made of metal.

[0030] According to one embodiment of this application, a second hook is provided on the inner side of the second cover. The second hook is formed by a bendable piece and is used to engage with the side of the first cover.

[0031] According to one embodiment of this application, a third hook is provided on the inner side of the second shell. The third hook is formed by a bendable piece and is used to engage with the side of the first shell.

[0032] According to one embodiment of this application, the inner top wall of the upper cover is provided with a first enclosure member, and the inner bottom wall of the bottom shell is provided with a second enclosure member. The first enclosure member and the second enclosure member are connected by insertion to form a vent, so that the storage spaces located on both sides of the partition can be interconnected through the vent and are both separated from the first foaming cavity.

[0033] According to one embodiment of this application, the partition further includes a front baffle installed on the front side of the upper cover, and the refrigeration device further includes:

[0034] The mouth frame is installed on the open side of the inner liner, connecting the outer shell and the inner liner, and is provided with a clearance groove. Both ends of the front baffle extend through the clearance groove to connect with the outer shell.

[0035] According to one embodiment of this application, the front baffle is embedded between the bottom shell and the top cover, and the rear wall of the front baffle is provided with a plurality of fourth hooks. The front side of the top cover is provided with a first hook interface for cooperating with some of the fourth hooks, and the front side of the bottom shell is provided with a second hook interface for cooperating with another part of the fourth hooks.

[0036] According to one embodiment of this application, the partition includes a plurality of protruding ribs that are disposed on the inner wall and spaced apart, the ribs being used to anchor the insulation layer in the second foaming cavity.

[0093] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0094] This application discloses a refrigeration device 10.

[0095] It should be noted that the refrigeration equipment in this embodiment includes, but is not limited to, refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines, etc. The refrigeration equipment 10 has a variety of structural forms and a wide range of applications.

[0096] The following is for reference. Figures 1 to 8 A refrigeration device 10 according to an embodiment of this application is described.

[0097] In some embodiments, refer to Figures 1 to 3 The refrigeration equipment 10 includes: an outer shell 11, an inner liner 12, an insulation layer, and an air duct cover 14.

[0098] The inner liner 12 forms an open compartment 121. The inner liner 12 is installed inside the outer shell 11. At least one wall of the inner liner 12 is a metal plate, and at least one wall of the inner liner 12 is provided with a first mounting hole 123. A mounting seat 193 is installed at the first mounting hole 123. An insulation layer is formed at least between the outer shell 11 and the inner liner 12, and a part of the mounting seat 193 is embedded in the insulation layer. The air duct cover 14 is installed in the compartment 121 through the mounting seat 193, and an air outlet channel 143 is formed between the air duct cover 14 and the inner liner 12.

[0099] In other words, the refrigeration device 10 provided in this application embodiment is an air-cooled refrigeration device, and the inner liner 12 is equipped with at least one air duct cover 14, the wall of which is a metal plate.

[0100] The metal may include, but is not limited to, stainless steel or aluminum alloy, etc., and the embodiments of this application do not limit this.

[0101] As an example, refer to Figure 3 The refrigeration equipment 10 can adopt a rear air outlet, that is, at least the back wall of the inner liner 12 is a metal plate, and the mounting base 193 is located on the back wall of the inner liner 12.

[0102] As an example, the refrigeration device 10 can adopt side air outlet, that is, at least one side wall of the inner liner 12 is a metal plate, and the mounting base 193 is provided on the side wall of the inner liner 12.

[0103] As an example, the refrigeration device 10 can adopt a combination of back air outlet and side air outlet, that is, at least the back wall and one side wall of the inner liner 12 are metal plates, and the mounting base 193 is provided on the back wall and side wall of the inner liner 12.

[0104] The shape of the first mounting hole 123 may include, but is not limited to, a circle, a square, an ellipse, a waist shape, a triangle, or a polygon, and the embodiments of this application do not impose any restrictions on this.

[0105] The mounting base 193 can be made of plastic, composite materials or ceramics, etc. The plastic material can include, but is not limited to, ABS (Acrylonitrile Butadiene Styrene), PU (Polyurethane), PS (Polystyrene) or HIPS (High Impact Polystyrene), etc. The embodiments of this application do not limit this.

[0106] There is a gap between the air duct cover 14 and at least one wall of the inner liner 12 to form an air outlet duct 143, through which the cold air from the refrigeration chamber of the refrigeration equipment 10 can be sent into the compartment 121 of the inner liner 12.

[0107] The duct cover 14 can be made of metal or plastic, etc., and this application embodiment does not limit it.

[0108] In actual implementation, refer to Figure 4 The assembly of the duct cover 14 on the corresponding wall of the inner liner 12 can be achieved in the following way: Before forming the insulation layer, the mounting base 193 is pre-installed between the inner liner 12 and the outer shell 11, that is, the mounting base 193 is pre-installed on the outer surface of the inner liner 12. Then, foam material is filled between the inner liner 12 and the outer shell 11. After the foam material cures to form an insulation layer, the mounting base 193 is not easy to move under the wrapping of the insulation layer. After the mounting base 193 is fixed, the duct cover 14 can be directly connected to the mounting base 193. The connection method can include, but is not limited to, snap-fit, plug-in, tenon and mortise connection or magnetic attraction. By connecting the duct cover 14 to the mounting base 193, the indirect installation of the duct cover 14 on the corresponding wall of the inner liner 12 is achieved.

[0109] Understandably, on the one hand, by pre-embedding an independent mounting base 193, taking the mounting base 193 as an example made of plastic, the mounting base 193 can be manufactured separately using processes such as injection molding. Injection molding can achieve one-time molding of complex curved surfaces and intricate connection structures, breaking through the geometric limitations of stamping. The connection structure of the mounting base 193 can be designed as a more refined, multi-angle locking structure, such as multi-angle buckles and irregular grooves, thereby significantly improving the stability and precision of the duct cover 14 installation. On the other hand, the mounting base 193 is wrapped and cured by an insulation layer. During the foaming process, the foaming material expands and fills the gap between the mounting base 193 and the inner liner 12, forming a dual fixation of mechanical fitting and chemical bonding, greatly enhancing the stability of the mounting base 193. The shear and pull-out resistance of the 3 further enhances the reliability and stability of the duct cover 14 installation. Furthermore, since the mounting base 193 is manufactured separately, it allows for pre-inspection and simplifies pre-embedding before foaming, significantly reducing the difficulty and cost of the inner liner 12 molding process. This reduces the production cost of the refrigeration equipment 10, accelerates production efficiency, and greatly improves the production yield and consistency of the refrigeration equipment 10. Moreover, as an independent component, the mounting base 193 can be partially replaced when damaged, without replacing the entire inner liner 12, thus significantly reducing maintenance costs. It also facilitates future upgrades to the connection structure on the mounting base 193, such as adapting it to the new duct cover 14, thereby extending the product lifecycle.

[0110] It should be noted that in some traditional refrigeration equipment, pre-embedded parts are introduced into the adsorption-molded plastic liner to indirectly install the air duct cover on the plastic liner. However, directly applying the above design concept of transferring pre-embedded parts to the plastic liner structure will cause many problems in practical applications: Firstly, because the deformation of the plastic liner during the foaming process is much greater than that of the metal liner, under the driving force of foaming pressure, the location where the pre-embedded parts are installed on the plastic liner is very likely to become a stress concentration point due to the opening. This causes the connection holes of the specified size on the plastic liner to be torn or squeezed during the foaming process, resulting in the pre-embedded parts pre-installed on the connection holes of the plastic liner loosening or even falling off directly. After the seal fails, the foamed material will leak out. Excessive overflow from severely deformed connection holes caused foaming failure, leading to a sharp increase in scrap rate. Secondly, since the process of directly adsorbing the connection structure used for installing the air duct cover from the plastic inner liner is already relatively mature and simple, switching to the assembly method of using embedded parts would actually make the processing steps redundant. Due to the addition of embedded parts, an additional production line for embedded parts would be needed, which would seriously affect production costs and efficiency. Compared to the negative impact of using embedded parts on the plastic inner liner, the advantages of introducing embedded parts for the air duct cover are insignificant.

[0111] The refrigeration equipment 10 provided in this application embodiment features a structural design where the aforementioned duct cover 14 is assembled into the inner liner 12 via a pre-embedded mounting base 193. Combined with the fact that the inner liner 12 is configured such that at least the wall surface fitted with the duct cover 14 is a metal plate, compared to a scheme where the inner liner 12 is directly connected to the duct cover 14, the mounting base 193 can be directly molded using processes such as injection molding to form a complex connection structure. Furthermore, the insulation layer solidifies and encapsulates the mounting base 193, enhancing its shear resistance and pull-out resistance. This significantly improves the reliability and stability of the duct cover 14 installation, while reducing the difficulty and cost of the inner liner 12 molding process. This reduces the production cost of the refrigeration equipment 10, accelerates production efficiency, and greatly improves the production yield and consistency of the refrigeration equipment 10. In addition, the mounting base 193 can be replaced independently, reducing maintenance costs and facilitating future upgrades to the connection structure of the mounting base 193, thereby extending the product lifecycle of the refrigeration equipment 10.

[0112] In some embodiments, refer to Figure 4 and Figure 5 The duct cover 14 is provided with a first snap-fit ​​member 144, and the mounting base 193 is provided with a second snap-fit ​​member 1931 for snap-fitting with the first snap-fit ​​member 144.

[0113] The first snap-fit ​​component 144 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring. Correspondingly, the second snap-fit ​​component 1931 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring that cooperates with the first snap-fit ​​component 144. This application embodiment does not limit this.

[0114] The refrigeration equipment 10 provided in this application embodiment, through the aforementioned first snap-fit ​​member 144 and second snap-fit ​​member 1931, allows for easy installation by simply aligning the first snap-fit ​​member 144 of the duct cover 14 with the second snap-fit ​​member 1931 of the mounting base 193, and completing the installation through simple pressing and insertion operations, without the need for tools. This improves the ease of connection between the duct cover 14 and the mounting base 193, thereby saving the time required for installation and disassembly, and improving maintenance efficiency. At the same time, the snap-fit ​​engagement provides sufficient connection strength, effectively reducing the risk of the duct cover 14 loosening and falling off even when subjected to external forces such as wind or vibration during the operation of the refrigeration equipment 10, maintaining the normal ventilation and temperature regulation functions of the refrigeration equipment 10. Furthermore, the shape and size of the first snap-fit ​​member 144 and the second snap-fit ​​member 1931 can be precisely controlled by a mold, thereby ensuring that the installation effect of the duct cover 14 of each refrigeration equipment 10 is as consistent as possible, improving the overall quality and consistency of the product, and facilitating large-scale production.

[0115] In some embodiments, refer to Figure 4 and Figure 5 The first snap-fit ​​member 144 includes a snap hook provided on the outer side wall of the air duct cover 14 and protruding towards at least one wall of the inner liner 12, and the second snap-fit ​​member 1931 includes a snap groove provided on the mounting base 193 and embedded in a part of the insulation layer.

[0116] The hook can be designed as an L-shaped hook, an arc hook, a forked hook, a spherical hook, or a wedge hook, etc., and the embodiments of this application do not limit it.

[0117] The shape of the card slot can be designed to match the shape of the card hook, including but not limited to rectangle, cone or trapezoid, etc., and the embodiments of this application do not limit this.

[0118] As an example, refer to Figure 8 The hook can be equipped with reinforcing ribs or other strengthening structures to increase its own strength, thereby increasing its fatigue strength under frequent use and long-term stress.

[0119] Understandably, on the one hand, the locking force direction of the hooks and slots is consistent with the direction of the internal wind pressure on the duct cover 14, which greatly improves the tensile strength of the duct cover 14. Since the slots are located in the pre-embedded part of the mounting base 193, the insulation layer wraps around the slots after curing, forming an anchoring effect. The external force is shared by the insulation layer and the mounting base 193, effectively reducing the risk of tearing caused by the mounting base 193 bearing the external force alone, thereby greatly improving the reliability and stability of the duct cover 14 installation. On the other hand, the protruding hooks form a cantilever design, which gives the hooks a large deformation capacity. Since there will inevitably be certain dimensional errors during the production process, the hooks can accommodate these errors through their own elastic deformation, reducing assembly failures and rework caused by size mismatch, thereby reducing the assembly difficulty of the duct cover 14 and improving the assembly efficiency of the duct cover 14.

[0120] In some embodiments, refer to Figure 2 , Figure 4 and Figure 5 Multiple hooks and slots are provided in a one-to-one correspondence, and at least two of the hooks have different hook body orientations.

[0121] Multiple hooks are spaced apart, and multiple slots are spaced apart, where "multiple" means two or more.

[0122] As an example, refer to Figure 2 , Figure 4 and Figure 5 With the mounting base 193 located on the back wall of the inner liner 12, among the multiple hooks, some hooks face upwards, some hooks face to the left, and the rest hooks face to the right.

[0123] As an example, when the mounting base 193 is located on the back wall of the inner liner 12, among the multiple hooks, some hooks face upwards, some hooks face to the left, some hooks face to the right, and the remaining hooks face downwards.

[0124] As an example, when the mounting base 193 is located on the back wall of the inner liner 12, some of the hooks face upwards and others face downwards.

[0125] As an example, when the mounting base 193 is located on the side wall of the inner liner 12, among the multiple hooks, some hooks face upwards, some hooks face forwards, some hooks face backwards, and the remaining hooks face downwards.

[0126] The refrigeration equipment 10 provided in this application embodiment has at least two hooks with different hook bodies. During the operation of the refrigeration equipment 10, the duct cover 14 may be subjected to external forces from various directions, such as the airflow impact force generated by the fan operation, the shaking caused by equipment vibration, and the pulling force caused by frequent opening and closing of the door. The hooks with different orientations can limit and fix the duct cover 14 from multiple angles. When an external force is applied in a certain direction, the hook with the corresponding orientation can directly resist the force in that direction. At the same time, the hooks in other directions can also play a role in assisting fixation and dispersing force, thereby significantly enhancing the stability and resistance to external forces of the connection between the duct cover 14 and the mounting base 193, and maintaining the normal operation of the ventilation system of the refrigeration equipment 10.

[0127] In some embodiments, refer to Figures 3 to 5 The groove edge of the card slot has a guide slope 1932, which is inclined towards the groove opening from one end near the compartment 121 to the other end away from the compartment 121.

[0128] The angle between the guide slope 1932 and the horizontal plane can be 15°, 30°, 45°, 60° or other angles, and the embodiments of this application do not limit this.

[0129] In actual implementation, refer to Figures 3 to 5 The guide slope 1932 extends outward from the opening of the slot, gradually becoming shallower. During the assembly of the duct cover 14 and the mounting base 193, the duct cover 14 is pushed backward, causing the hook to first contact the guide slope 1932. Based on the guide slope 1932 being inclined from the end near the compartment 121 to the end away from the compartment 121 towards the opening of the slot, the hook continues to move backward, generating sliding friction between the hook and the guide slope 1932. Guided by the guide slope 1932, the hook body slides from the opening of the slot into the slot. Adjusting the position of the hook makes it engage with the slot, completing the connection.

[0130] The refrigeration equipment 10 provided in this application embodiment, through the setting of the above-mentioned guide slope 1932, can provide a clear guiding direction for the hook during the installation of the air duct cover plate 14. It is not necessary to precisely align the hook and the slot. As long as they are roughly close, the hook can automatically slide into the slot under the action of the guide slope 1932, which significantly reduces the installation difficulty, effectively shortens the installation time, and thus greatly improves the production efficiency.

[0131] In some embodiments, refer to Figure 4 and Figure 5 The mounting base 193 has a first protrusion 1933 protruding from the compartment 121 on the side facing the insulation layer. The first protrusion 1933 is used to anchor the insulation layer.

[0132] The first convex hull 1933 can be designed as a cylinder, cone, prism, hemisphere, or irregular shape, etc., and the embodiments of this application do not limit this.

[0133] In this embodiment, refer to Figure 4 and Figure 5 With the mounting base 193 located on the back wall of the inner liner 12, the first protrusion 1933 protrudes rearward relative to the back wall of the inner liner 12. The first protrusion 1933 can be configured to bulge upward, downward, leftward, or rightward. After the foaming material is foamed and cured, it forms an insulation layer that wraps around the first protrusion 1933. The first protrusion 1933 can significantly increase the contact area between the mounting base 193 and the insulation layer. The raised portion of the first protrusion 1711 can effectively restrict the misalignment between the mounting base 193 and the insulation layer in the front-to-back direction. In this way, the mounting base 193 can grip the insulation layer as tightly as possible.

[0134] The refrigeration device 10 provided in this application embodiment, through the setting of the first protrusion 1933, increases the bonding strength between the mounting base 193 and the insulation layer by utilizing the mechanical anchoring effect of the first protrusion 1933. During the curing process of the insulation layer, the first protrusion 1933 can be embedded in the insulation layer, increasing the contact area and friction between the mounting base 193 and the insulation layer, thereby enhancing the tensile strength and shear strength of the mounting base 193, reducing the risk of the mounting base 193 peeling off from the insulation layer when the duct cover 14 is under stress, and further improving the reliability and stability of the installation of the duct cover 14.

[0135] In some embodiments, refer to Figure 4 and Figure 5 The mounting base 193 has a first positioning boss 1934 protruding toward the air duct cover 14, the first positioning boss 1934 being adapted to extend into the first mounting hole 123.

[0136] The first positioning boss 1934 is used to position and engage with the first mounting hole 123 of the inner liner 12 during the assembly of the mounting base 193. One or more first positioning bosses 1934 may be provided, with "multiple" meaning two or more.

[0137] The first positioning boss 1934 can be designed as a block, a strip, a ring, or an irregular shape, etc., and the embodiments of this application do not limit this.

[0138] The fit between the first positioning boss 1934 and the first mounting hole 123 can be a transition fit, an interference fit, or a clearance fit, and this application embodiment does not limit this.

[0139] The protrusion height of the first positioning boss 1934 can be designed according to factors such as the thickness of the inner liner 12, and this embodiment does not limit it.

[0140] The refrigeration equipment 10 provided in this application embodiment, through the setting of the first positioning boss 1934, extends into the first mounting hole 123, providing a clear positioning reference for the mounting base 193 and the inner liner 12. The mounting base 193 can be accurately positioned during the installation process, so that the mounting base 193 can be precisely aligned with the air duct cover 14, reducing the installation misalignment of the air duct cover 14 due to positional deviation, significantly improving the installation accuracy of the air duct cover 14. Furthermore, during the assembly process, it is only necessary to align the first positioning boss 1934 with the first mounting hole 123 and insert it, without the need for complex measurement and adjustment steps, thereby reducing the installation difficulty, reducing the installation time, and thus improving the assembly efficiency.

[0141] In some embodiments, refer to Figure 5 The first positioning boss 1934 has an annular structure, and the outer contour of the first positioning boss 1934 is similar to that of the first mounting hole 123. The outer wall of the first positioning boss 1934 abuts against the wall of the first mounting hole 123.

[0142] Specifically, the first positioning boss 1934 can be, but is not limited to, a square ring, a circular ring, or an irregular ring, etc., and the embodiments of this application do not limit this.

[0143] Understandably, the first positioning boss 1934 adopts an annular structure that conforms to the outer contour of the first mounting hole 123, and its outer wall abuts against the hole wall. This design provides the mounting base 193 with a comprehensive and tight positioning method. The annular structure can limit the mounting base 193 from multiple directions, effectively reducing the loosening or displacement of the mounting base 193 during the foaming process or use, and improving the overall reliability of the refrigeration equipment 10 structure. At the same time, since the first positioning boss 1934 and the first mounting hole 123 are sealed together, the probability of gaps between the first positioning boss 1934 and the first mounting hole 123 is minimized, significantly reducing the risk of foam material overflowing from gaps or condensate leaking from gaps, thereby enhancing the sealing performance and antibacterial performance of the inner liner 12.

[0144] In some embodiments, refer to Figure 5 The edge of the mounting base 193 is sealed to the outer periphery of the first mounting hole 123.

[0145] The sealing method between the edge of the mounting base 193 and the outer periphery of the first mounting hole 123 may include, but is not limited to, elastic sealing ring sealing, sealing film heat sealing, liquid sealant bonding, sealing tape application, heat melt sealing or sealing gasket sealing, etc., and the embodiments of this application do not limit this.

[0146] The sealing material may include, but is not limited to, PE (Polyethylene) film, silicone rubber, or polyurethane elastomer, etc., and the embodiments of this application do not limit this.

[0147] The area of ​​the sealing interface between the edge of the mounting base 193 and the outer periphery of the first mounting hole 123 can be customized according to actual needs, and this embodiment does not limit this.

[0148] The refrigeration device 10 provided in this application embodiment, through the structural design of the sealing fit between the edge of the mounting base 193 and the outer periphery of the first mounting hole 123, effectively prevents the foaming material from overflowing through the gap between the mounting base 193 and the inner liner 12, so that the foaming material can only fill within the predetermined space, maintaining the integrity and uniformity of the insulation layer, effectively alleviating the local decrease in insulation performance caused by the overflow of foaming material, and at the same time preventing condensate from seeping into the insulation layer along the gap between the mounting base 193 and the inner liner 12, thereby significantly reducing the corrosion rate of the inner liner 12, effectively reducing mold growth, and thus maximizing the sealing performance and antibacterial performance of the inner liner 12.

[0149] In some embodiments, refer to Figure 2 Multiple mounting bases 193 are provided separately, and the multiple mounting bases 193 are distributed on multiple edges of the inner liner 12.

[0150] "Multiple" here means two or more.

[0151] In this embodiment, refer to Figure 2 Multiple mounting bases 193 are distributed along the three edges of the inner liner 12.

[0152] In other embodiments, multiple mounting bases 193 may be distributed along the four edges of the inner liner 12.

[0153] In some other embodiments, a plurality of mounting bases 193 may be distributed along the two edges of the inner liner 12.

[0154] The refrigeration equipment 10 provided in this application embodiment uses a layout design in which multiple mounting seats 193 are distributed along multiple edges of the inner liner 12. The multiple mounting seats 193 fix and support the air duct cover 14 from different positions. The multiple mounting seats 193 distribute the weight and air pressure of the air duct cover 14 to different positions along the edge of the inner liner 12, so that the air duct cover 14 is subjected to more uniform force after installation, reducing the force distribution of a single mounting seat 193, and alleviating the displacement, deformation or loosening of the air duct cover 14 and mounting seats 193 under local overload.

[0155] In some embodiments, refer to Figure 4 The duct cover 14 includes: a cover body 141 and a frame 142.

[0156] The cover body 141 is spaced apart from at least one wall of the inner liner 12 to form an air outlet channel 143; the frame 142 is connected to the cover body 141, the frame 142 is snapped into the mounting base 193, and the frame 142 protrudes relative to the cover body 141 toward at least one wall of the inner liner 12, and the frame 142 is spaced apart from at least one wall of the inner liner 12.

[0157] In this embodiment, refer to Figure 4 The cover plate body 141 is vertically arranged on the back wall of the inner liner 12. The cover plate body 141 and the back wall of the inner liner 12 are spaced apart to form an air outlet duct 143 at the back of the compartment 121. The frame 142 is connected to the edge of the cover plate body 141. A first snap-fit ​​member 144 can be connected to the rear side of the frame 142. A second snap-fit ​​member 1931 can be provided on the mounting base 193. The first snap-fit ​​member 144 and the second snap-fit ​​member 1931 are snap-fitted together to realize the snap-fit ​​connection between the frame 142 and the mounting base 193. The rear side wall of the frame 142 is spaced apart from the back wall of the inner liner 12 to avoid large-area contact heat exchange between the inner liner 12 and the air duct cover plate 14.

[0158] The connection method between the cover plate body 141 and the frame 142 may include, but is not limited to, integral molding, bolt connection, welding connection or snap-fit, etc., and the embodiments of this application do not limit this.

[0159] The refrigeration equipment 10 provided in this application embodiment, through the structural design of the cover body 141 and the frame 142, the protruding frame 142 replaces the cover body 141 and is snapped into the mounting base 193, which distributes more mechanical stress as much as possible, helps to reduce the fatigue of the cover body 141 under long-term use, thereby extending the service life of the entire air duct cover 14. Combined with the non-contact spacing design between the frame 142 and the inner liner 12, the probability of forming a cold bridge due to direct contact between the frame 142 and the inner liner 12 wall is reduced, effectively reducing the heat exchange between the inner liner 12 and the air duct cover 14, thereby alleviating the condensation phenomenon on the inner liner 12 wall.

[0160] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 The refrigeration device 10 also includes: a first light source 194 and a second light source 195.

[0161] The first light source 194 is installed on the frame 142 and is located on the side of the air duct cover 14 away from the air outlet 143; the second light source 195 is located on the top wall of the inner liner 12 and is connected to the inner liner 12 and the first light source 194.

[0162] The first surface light source 194 can be, but is not limited to, an LED (light-emitting diode) surface light source, an OLED (Organic Light-Emitting Diode) surface light source, or a fluorescent surface light source, etc., and the embodiments of this application do not limit this.

[0163] The second surface light source 195 can be, but is not limited to, an LED (light-emitting diode) surface light source, an OLED (Organic Light-Emitting Diode) surface light source, or a fluorescent surface light source, etc., and the embodiments of this application do not limit this.

[0164] The connection method between the first light source 194 and the frame 142 includes, but is not limited to, plug-in, snap-in or bolt connection, etc., and the embodiments of this application do not limit this.

[0165] The connection methods between the second light source 195 and the first light source 194 include, but are not limited to, plug-in, snap-in, or bolt connection, and the embodiments of this application do not limit this.

[0166] The connection between the second light source 195 and the inner liner 12 includes, but is not limited to, bolt connection, snap-fit ​​or riveting, and this application embodiment does not limit this.

[0167] The refrigeration device 10 provided in this application embodiment provides light from different angles and positions through the arrangement of the first light source 194 and the second light source 195, eliminating blind spots and allowing users to see the items in the storage space 1211 more clearly, thus improving the user experience and display effect. At the same time, the first light source 194 covers the side of the air duct cover 14 near the compartment 121, hiding the cover body 141, making the internal visual effect of the refrigeration device 10 more concise and beautiful. Furthermore, without affecting the normal air supply of the air outlet duct 143, the first light source 194 is integrated into the air duct cover 14, improving the space utilization of the refrigeration device 10. In addition, the adjacent first light source 194 and second light source 195 are assembled with each other, further increasing the stability and reliability of the installation of the first light source 194 and the second light source 195 on the basis of the original installation.

[0168] In some embodiments, refer to Figure 4 and Figure 7 The first light source 194 includes: a first frame 1941, a first light guide assembly 1942, and a first light emitter 1943.

[0169] The first frame 1941 is mounted on the frame 142; the first light guide assembly 1942 is mounted on the first frame 1941; and the first light emitter 1943 is mounted on the end of the first light guide assembly 1942.

[0170] As an example, the upper end of the first frame 1941 can be directly inserted into the upper end of the frame 142, and the lower end of the frame 142 can cover the lower edge of the first frame 1941. In addition, at least one of the left and right sides of the frame 142 can be provided with a connecting frame to further fix the first frame 1941.

[0171] The first light-emitting element 1943 may include, but is not limited to, LED (light-emitting diode) chips, LED (light-emitting diode) light strips, or OLED (Organic Light-Emitting Diode) light-emitting sheets, etc.

[0172] The first light guide assembly 1942 may include a first light-transmitting plate, a first light guide plate, and a first reflective sheet stacked sequentially from the inside out. A first light-emitting element 1943 may be at least partially positioned facing the edge of the first light guide plate. At least a portion of the light emitted by the first light-emitting element 1943 enters the first light guide plate from its edge. The orthographic projection of the first light guide plate onto the first reflective sheet falls within the area of ​​the first reflective sheet. The first light guide plate disperses the light from the first light-emitting element 1943 and emits it uniformly from one side, forming a uniform surface light. This surface light can simultaneously illuminate the object from multiple angles through the first light-transmitting plate, ensuring that all parts of the object receive sufficient light. When the surface light illuminates the surface of the object, optical phenomena such as reflection, refraction, and absorption occur. The combined effect of these phenomena gives the object a three-dimensional appearance. The first reflective sheet can reflect all the light emitted from the first light guide plate back to the first light-transmitting plate, significantly increasing light intensity and improving illumination brightness, thereby enhancing the user experience.

[0173] In some embodiments, refer to Figure 6 The second light source 195 includes: a second frame 1951, a second light guide assembly 1952, and a second light emitter 1953.

[0174] The second frame 1951 is connected to the first frame 1941; the second light guide assembly 1952 is installed on the second frame 1951; the second light emitter 1953 is installed at the end of the second light guide assembly 1952.

[0175] As an example, refer to Figure 6 and Figure 7 The front end of the second frame 1951 can be installed on the top wall of the inner liner 12 by means of snap-fit, riveting or bolt connection, and the rear end of the second frame 1951 can be connected to the upper end of the first frame 1941 by means of snap-fit, riveting or bolt connection.

[0176] The second light-emitting element 1953 may include, but is not limited to, LED (light-emitting diode) chips, LED (light-emitting diode) light strips, or OLED (Organic Light-Emitting Diode) light-emitting sheets, etc.

[0177] The second light guide assembly 1952 may include a second light-transmitting plate, a second light guide plate, and a second reflective sheet stacked sequentially from the inside out. At least a portion of the second light-emitting element 1953 may be positioned directly opposite the edge of the second light guide plate. At least a portion of the light emitted by the second light-emitting element 1953 enters the second light guide plate from its edge. The orthographic projection of the second light guide plate onto the second reflective sheet falls within the area of ​​the second reflective sheet. The second light guide plate disperses the light from the second light-emitting element 1953 and emits it uniformly from both sides, forming uniform surface light. This surface light can simultaneously illuminate the object from multiple angles through the second light-transmitting plate, ensuring that all parts of the object receive sufficient light. When the surface light illuminates the surface of the object, optical phenomena such as reflection, refraction, and absorption occur. The combined effect of these phenomena gives the object a three-dimensional appearance. The second reflective sheet can reflect all the light emitted from the second light guide plate back to the second light-transmitting plate, significantly increasing light intensity and improving illumination brightness, thereby enhancing the user experience.

[0178] In some embodiments, refer to Figure 7 The first frame 1941 is provided with a third snap-fit ​​member 19411, and the second frame 1951 is provided with a fourth snap-fit ​​member 19511 for snap-fitting with the third snap-fit ​​member 19411.

[0179] The third snap-fit ​​component 19411 may include, but is not limited to, a snap fastener, a snap tooth, a hook, a protrusion, a slot, or a hanging ring. Correspondingly, the fourth snap-fit ​​component 19511 may include, but is not limited to, a snap fastener, a snap tooth, a hook, a protrusion, a slot, or a hanging ring that cooperates with the third snap-fit ​​component 19411. This application embodiment does not limit this.

[0180] For example, in one embodiment, reference Figure 7 The third connector 19411 is a protrusion, and the fourth connector 19511 is a slot.

[0181] The refrigeration device 10 provided in this application embodiment, through the setting of the third snap-fit ​​component 19411 and the fourth snap-fit ​​component 19511, realizes the snap-fit ​​assembly between the first light source 194 and the second light source 195, effectively reducing the relative displacement or loosening between the first light source 194 and the second light source 195, so that the first light source 194 and the second light source 195 always remain in the correct position and maintain the lighting effect. At the same time, the connection between the first frame 1941 and the second frame 1951 does not require the use of screws or other parts, which greatly simplifies the installation and disassembly process, improves operating efficiency, and reduces maintenance costs.

[0182] In some embodiments, refer to Figure 8 At least one wall of the inner liner 12 is provided with a second mounting hole 124, and an electrical control embedded box 196 is installed at the second mounting hole 124. A part of the electrical control embedded box 196 is embedded in the insulation layer.

[0183] The shape of the second mounting hole 124 may include, but is not limited to, a circle, a square, an ellipse, a waist shape, a triangle, or a polygon, and this application embodiment does not impose any restrictions on this.

[0184] The electrical control embedded box 196 can be used to install small electrical control components such as temperature controllers, sensors and power cords. During installation, the embedded box is inserted into the second mounting hole 124, with part of it embedded in the insulation layer and the remaining part exposed for installation and connection of electrical control components.

[0185] In actual implementation, the assembly of the electrical control embedded box 196 on the back wall of the inner liner 12 can be achieved in the following way: before forming the insulation layer, the electrical control embedded box 196 is pre-installed between the inner liner 12 and the outer shell 11, that is, the electrical control embedded box 196 is assembled on the outer surface of the inner liner 12. Then, foaming material is filled between the inner liner 12 and the outer shell 11. After the foaming material cures to form an insulation layer, the electrical control embedded box 196 is not easy to move under the wrapping of the insulation layer, thus completing the assembly.

[0186] The refrigeration equipment 10 provided in this application embodiment, through the assembly design of the above-mentioned electrical control embedded box 196 and inner liner 12, the insulation layer solidifies and wraps the electrical control embedded box 196, which significantly improves the reliability and stability of the installation of the electrical control embedded box 196. It eliminates the need for screws or other parts, reduces the processing difficulty of the inner liner 12, thereby reducing the production cost of the refrigeration equipment 10, accelerating production efficiency, and greatly improving the production yield and consistency of the refrigeration equipment 10. In addition, the electrical control embedded box 196 and the air duct cover 14 are arranged on the same wall of the inner liner 12. The cold air in the air outlet duct 143 can carry away the large amount of heat generated by the electrical control components installed on the electrical control embedded box 196, realizing efficient heat dissipation and cooling of the electrical control components.

[0187] In some embodiments, refer to Figure 8The electrical control embedded box 196 mounting base 193 forms a second protrusion 1961 protruding away from the compartment 121 on the side facing the insulation layer. The second protrusion 1961 is used to anchor the insulation layer.

[0188] The second convex hull 1961 can be designed as a cylinder, cone, prism, hemisphere, or irregular shape, etc., and the embodiments of this application do not limit this.

[0189] In this embodiment, refer to Figure 8 The second protrusion 1961 protrudes backward relative to the back wall of the inner liner 12. After the foam material is foamed and cured, it forms an insulation layer that wraps around the second protrusion 1961. The second protrusion 1961 can significantly increase the contact area between the electrical control embedded box 196 and the insulation layer, effectively limiting the misalignment between the electrical control embedded box 196 and the insulation layer. In this way, the electrical control embedded box 196 can grip the insulation layer as tightly as possible.

[0190] The refrigeration device 10 provided in this application embodiment, through the setting of the second protrusion 1961, increases the bonding strength between the electrical control embedded box 196 and the insulation layer by utilizing the mechanical anchoring effect of the second protrusion 1961. During the curing process of the insulation layer, the second protrusion 1961 can be embedded in the insulation layer, increasing the contact area and friction between the electrical control embedded box 196 and the insulation layer, thereby enhancing the pull-out resistance and shear strength of the electrical control embedded box 196, reducing the risk of the electrical control embedded box 196 peeling off from the insulation layer, and thus improving the reliability and stability of the installation of the electrical control embedded box 196.

[0191] In some embodiments, refer to Figure 8 The electrical control embedded box 196 has a second positioning boss 1962 that protrudes away from the insulation layer, and the second positioning boss 1962 is adapted to extend into the second mounting hole 124.

[0192] The second positioning boss 1962 can be set one or more, where multiple means two or more.

[0193] The second positioning boss 1962 can be designed as a block, strip, ring or irregular shape, etc., and the embodiments of this application do not limit it.

[0194] As an example, refer to Figure 8 The second positioning boss 1962 may include a bent strip segment and at least one flange connected to the outer wall of the strip segment. The strip segment may be configured to conform to a portion of the outer contour of the second mounting hole 124. The flange may be designed as a semi-circle to further optimize the positioning prompting effect.

[0195] As an example, the second positioning boss 1962 can be designed as a ring.

[0196] The fit between the second positioning boss 1962 and the second mounting hole 124 can be a transition fit, an interference fit, or a clearance fit, and this application embodiment does not limit this.

[0197] As an example, refer to Figure 8 The outer wall of the second positioning boss 1962 abuts against the wall of the second mounting hole 124.

[0198] The protrusion height of the second positioning boss 1962 can be designed according to factors such as the thickness of the inner liner 12, and this embodiment does not limit it.

[0199] The refrigeration equipment 10 provided in this application embodiment, through the setting of the second positioning boss 1962, extends into the second mounting hole 124, providing a clear positioning reference for the electrical control embedded box 196 and the inner liner 12. The electrical control embedded box 196 can be accurately positioned during installation, reducing the misalignment of the electrical control embedded box 196 due to positional deviation, thereby improving the installation accuracy of the electrical control embedded box 196. Furthermore, during assembly, it is only necessary to align the second positioning boss 1962 with the second mounting hole 124 and insert it, without the need for complex measurement and adjustment steps, thereby reducing the installation difficulty of the electrical control embedded box 196, reducing the installation time, and thus improving the assembly efficiency of the electrical control embedded box 196.

[0200] In some embodiments, refer to Figure 8 The edge of the electrical control embedded box 196 is sealed to the outer periphery of the second mounting hole 124.

[0201] The sealing method between the edge of the electrical control embedded box 196 and the outer periphery of the second mounting hole 124 may include, but is not limited to, elastic sealing ring sealing, sealing film heat sealing, liquid sealant bonding, sealing tape application, heat melt sealing or sealing gasket sealing, etc., and the embodiments of this application do not limit this.

[0202] The sealing material may include, but is not limited to, PE (Polyethylene) film, silicone rubber, or polyurethane elastomer, etc., and the embodiments of this application do not limit this.

[0203] The area of ​​the sealing interface between the edge of the electrical control embedded box 196 and the outer periphery of the second mounting hole 124 can be customized according to actual needs, and this application embodiment does not limit this.

[0204] The refrigeration equipment 10 provided in this application embodiment, through the structural design of the sealing fit between the edge of the above-mentioned electrical control embedded box 196 and the outer periphery of the second mounting hole 124, effectively prevents the foaming material from overflowing through the gap between the electrical control embedded box 196 and the inner liner 12, so that the foaming material can only fill within the predetermined space, maintaining the integrity and uniformity of the insulation layer, effectively alleviating the local decrease in insulation performance caused by the overflow of foaming material, and at the same time preventing condensate from seeping into the insulation layer along the gap between the electrical control embedded box 196 and the inner liner 12, thereby significantly reducing the corrosion rate of the inner liner 12, effectively reducing mold growth, and thus enhancing the sealing performance and antibacterial performance of the inner liner 12.

[0205] This application discloses a refrigeration device 10.

[0206] It should be noted that the refrigeration equipment in this embodiment includes, but is not limited to, refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines, etc. The refrigeration equipment 10 has a variety of structural forms and a wide range of applications.

[0207] The following is for reference. Figures 9 to 27 A refrigeration device 10 according to an embodiment of this application is described.

[0208] In some embodiments, refer to Figures 9 to 13 The refrigeration equipment 10 includes: an outer shell 11, an inner liner 12, a partition 15, a filling component 16, and an insulation layer.

[0209] The inner liner 12 is installed inside the outer shell 11, forming a compartment 121 with one side open. The side wall of the inner liner 12 is a metal plate, and a first foaming cavity 101 is formed between the inner liner 12 and the outer shell 11. A partition 15 is provided in the compartment 121, which is used to divide the compartment 121 into multiple storage spaces 1211, and the partition 15 forms a second foaming cavity 102. An injection component 16 is installed on the outside of the side wall of the inner liner 12, and a part of the injection component 16 extends into the compartment 121 and connects with the partition 15. The injection component 16 connects the first foaming cavity 101 and the second foaming cavity 102. An insulation layer is formed in the first foaming cavity 101 and the second foaming cavity 102.

[0210] In other words, at least the left and right walls of the inner liner 12 used for mounting the partition 15 are metal plates.

[0211] Specifically, the inner liner 12 may have a structural form including, but not limited to, at least one of the following:

[0212] Firstly, the inner liner 12 includes: a first shell and a second shell.

[0213] In this embodiment, the first shell includes a first plate, a second plate, and a third plate that are bent and connected in sequence, and the first plate and the third plate are arranged opposite to each other; wherein, the first shell and the second shell are both metal plates, the second shell includes a fourth plate and a fifth plate that are bent and connected, the fourth plate is arranged opposite to the opening of the compartment 121, and the fourth plate is connected to the first plate to the third plate, the fifth plate is connected to the first plate and the third plate, and the fifth plate is arranged opposite to the second plate.

[0214] Secondly, the inner liner 12 includes: the outer shell, the fourth plate, and the fifth plate.

[0215] In this embodiment, the shell includes a first plate, a second plate, and a third plate that are bent and connected in sequence, with the first plate and the third plate being arranged opposite to each other; the fourth plate and the fifth plate are both connected to the shell, wherein at least one of the fourth plate and the fifth plate, as well as the shell, are metal plates.

[0216] The metal may include, but is not limited to, stainless steel or aluminum alloy, etc., and the embodiments of this application do not limit this.

[0217] Reference Figure 9 , Figure 10 , Figure 13 and Figure 23 The partition 15 can be placed horizontally, and the partition 15 has a hollow structure, and the internal cavity can form a second foaming cavity 102.

[0218] The volumes of the multiple storage spaces 1211 separated by the partition 15 can be equal or differentiated according to specific usage scenarios. This application embodiment does not impose any restrictions on this.

[0219] One or more partitions 15 can be provided. Multiple partitions 15 can be installed in the compartment 121 at intervals along the vertical direction. Here, "multiple" means two or more.

[0220] As an example, refer to Figure 9 and Figure 10 A partition 15 can be installed in the room 121 to divide the room 121 into two storage spaces 1211.

[0221] As an example, two partitions 15 can be installed in the compartment 121 to divide the compartment 121 into three storage spaces 1211.

[0222] The injection part 16 is used to help fix the partition 15 to the inner liner 12, that is, the partition 15 can be indirectly assembled on the inner liner 12 through the injection part 16.

[0223] It should be noted that, due to the difficulty in processing complex shapes made of metal materials and the difficulty in controlling processing precision, the injection part 16 can be made of plastic, composite materials or ceramics.

[0224] For example, considering factors such as material cost, processing difficulty, and structural strength, the injection-molded part 16 is made of plastic and formed through processes such as injection molding. The plastic material may include, but is not limited to, ABS (Acrylonitrile Butadiene Styrene), PU (Polyurethane), PS (Polystyrene), or HIPS (High Impact Polystyrene), etc., and this embodiment does not impose any limitations on this.

[0225] The connection between the injection part 16 and the partition plate 15 can be, but is not limited to, bolt connection, plug-in connection, snap-fit, riveting or interference fit, etc., and the embodiments of this application do not limit this.

[0226] In actual implementation, the assembly of the partition 15 can be achieved as follows: Before forming the insulation layer, the injection component 16 is pre-installed between the inner liner 12 and the outer shell 11. The partition 15 is pre-fixed to the side walls of the inner liner 12 along both sides in the left-right direction through the injection component 16. The foaming material is injected from the injection port on the outer shell 11, first filling the first foaming cavity 101 between the outer shell 11 and the inner liner 12, and then filling the second foaming cavity 102 in the partition 15 through the injection component 16. After the foaming material expands, it fills the first foaming cavity 101 and the second foaming cavity 102. The foaming material wraps around the injection component 16, and after curing, it forms a continuous insulation layer. This allows the injection component 16 to be fully embedded in the insulation layer, thereby distributing the installation force of the partition 15 to the entire insulation layer through the injection component 16, rather than relying on the deformation of the inner liner 12. Under the anchoring force of the insulation layer, the injection component 16 is less likely to shift between the inner liner 12 and the partition 15, thus achieving a secure installation of the partition 15. In addition, due to the tight wrapping and compression of the insulation layer, the gap between the injection component 16 and the inner liner 12 and the partition 15 is significantly reduced, thereby improving the sealing performance of the partition 15.

[0227] The refrigeration equipment 10 provided in this application embodiment, through the structural design of the partition 15 being indirectly installed in the inner liner 12 using the injection molding component 16, has a solidified insulation layer that wraps around the injection molding component 16. This allows the injection molding component 16 to be securely fixed to the side wall of the inner liner 12 under the anchoring force of the insulation layer. Furthermore, it increases the bonding force between the injection molding component 16 and the partition 15 on the basis of the original connection, distributing the installation force of the partition 15 to the entire insulation layer through the injection molding component 16. This effectively solves the problem that the high hardness of the metal inner liner 12 means that its deformation alone is insufficient to fix the partition 15, thereby significantly improving the reliability and stability of the partition 15 installation. It also significantly optimizes the sealing performance of the partition 15, reduces the risk of foam material leakage, and maintains the integrity and insulation effect of the insulation layer. At the same time, it achieves integrated foaming of the partition 15 and the main structure of the refrigeration equipment 10, simplifying the production process and thus improving production efficiency.

[0228] In some embodiments, refer to Figures 12 to 14 The injection component 16 passes through the inner liner 12 and the partition 15. The side of the injection component 16 closest to the compartment 121 is provided with a first snap-fit ​​structure 161, and the partition 15 is provided with a second snap-fit ​​structure 156. The first snap-fit ​​structure 161 and the second snap-fit ​​structure 156 are snap-fitted together to clamp the inner liner 12 between the injection component 16 and the partition 15.

[0229] The first snap-fit ​​structure 161 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring. Correspondingly, the second snap-fit ​​structure 156 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring that cooperates with the first snap-fit ​​structure 161. This application embodiment does not limit this.

[0230] In this embodiment, refer to Figure 13 The injection element 16 penetrates the side wall of the chamber 121 and the side wall of the partition 15. Specifically, the part of the injection element 16 extending into the chamber 121 passes into the interior of the partition 15, that is, into the second foaming cavity 102, and is locked with the second locking structure 156 inside the partition 15 through the first locking structure 161. In this way, the injection element 16 connected to both ends of the partition 15 in the left and right directions generates a tensile force on the partition 15 in the left and right directions, forcing the two side walls of the partition 15 in the left and right directions to press against the two side walls of the inner liner 12 respectively under the action of the locking force. That is, the side walls of the inner liner 12 are clamped between the part of the injection element 16 located in the first foaming cavity 101 and the side wall of the partition 15.

[0231] The refrigeration equipment 10 provided in this application embodiment uses a filling component 16 inserted into the inner liner 12 and the partition 15. The first snap-fit ​​structure 161 and the second snap-fit ​​structure 156 engage to provide initial installation positioning force. After the foamed material cures, secondary reinforcement is formed. The combined effect of these two structures makes the connection between the partition 15 and the inner liner 12 tighter and more secure, reducing the possibility of the partition 15 shaking during use and greatly improving the stability of the partition 15 installation. Since the inner liner 12 is clamped between the filling component 16 and the partition 15, the installation force is evenly transmitted to the entire side wall of the inner liner 12 through the snap-fit ​​position, reducing deformation or cracking of the inner liner 12 due to localized stress concentration, improving structural durability, and further reducing the gap between the filling component 16, the inner liner 12, and the partition 15, thus reducing the risk of foamed material leakage during the foaming process. In addition, it enables rapid pre-installation of the partition 15, shortening assembly time. The standardized snap-fit ​​interface facilitates automated assembly line operations, reduces manual alignment errors, and improves production efficiency.

[0232] In some embodiments, refer to Figure 13 , Figure 14 and Figures 18 to 20 The first snap-fit ​​structure 161 includes a plurality of snap hooks arranged separately, at least two of which have hooks facing different directions. The second snap-fit ​​structure 156 includes a plurality of protrusions protruding from the inner wall of the partition 15.

[0233] Multiple hooks and multiple protrusions are engaged in a one-to-one engagement, where "multiple" means two or more.

[0234] As an example, refer to Figure 13 and Figure 14 Among the multiple hooks, some hooks face upwards and some hooks face downwards.

[0235] As an example, among multiple hooks, some hooks face upwards, some hooks face to the left, some hooks face to the right, and the rest hooks face downwards.

[0236] As an example, among multiple hooks, some hooks face to the left, while others face to the right.

[0237] The hook can be designed as an L-shaped hook, an arc hook, a forked hook, a spherical hook, or a wedge-shaped hook, etc., and the embodiments of this application do not limit this.

[0238] The boss can be located near the through-hole of the injection part 16 on the partition 15. The shape of the boss can be designed to match the shape of the hook, including but not limited to square, cylindrical or trapezoidal shapes, etc. This application embodiment does not limit this.

[0239] The refrigeration equipment 10 provided in this application embodiment, through the arrangement of the above-mentioned multiple hooks and multiple bosses, combined with the fact that at least two of the multiple hooks have different hook orientations, makes the snap-fit ​​between the first snap-fit ​​structure 161 and the second snap-fit ​​structure 156 have multi-directional restrictions. When the partition 15 is subjected to external forces in different directions, the hooks with different hook orientations can provide snap-fit ​​forces from different angles, reducing the displacement of the partition 15 in the horizontal, vertical or other directions, greatly enhancing the stability of the snap-fit, and helping the partition 15 to always be firmly fixed on the inner liner 12. In addition, due to the cantilever structure of the hooks themselves, the hooks have a large deformation capacity. Since there will inevitably be certain dimensional errors during the production process, the hooks can accommodate these errors through their own elastic deformation, reducing assembly failures and rework caused by size mismatch, thereby reducing the assembly difficulty of the partition 15 and the injection part 16, and thus improving the assembly efficiency of the partition 15 and the injection part 16.

[0240] In some embodiments, refer to Figure 13 and Figure 14 The injection component 16 includes a substrate 162 and a guide structure 163 protruding from the substrate 162 toward the chamber 121. The substrate 162 is located in the first foaming chamber 101 and abuts against the outer surface of the inner liner 12. The guide structure 163 passes through the inner liner 12 and the partition 15. The guide structure 163 is engaged with the partition 15 and forms a feeding channel 1631 for connecting the first foaming chamber 101 and the second foaming chamber 102. The outer surface of the guide structure 163 is sealed to the inner liner 12 and the partition 15.

[0241] The shape of the guide structure 163 can be, but is not limited to, cylindrical, square, prismatic, frustum conical, or multi-step, etc., and the embodiments of this application do not impose such limitations.

[0242] In this embodiment, refer to Figure 13 and Figure 14 In some embodiments, the dimension of the feed channel 1631 along the feed direction remains constant. In other embodiments, the dimension of the feed channel 1631 gradually increases along the feed direction. In still other embodiments, a portion of the feed channel 1631 gradually increases in size along the feed direction. This application does not impose any limitations on this aspect.

[0243] In actual implementation, refer to Figure 13 and Figure 14Before foaming, the injection component 16 is installed from the outside on the side wall of the inner liner 12. The substrate 162 of the injection component 16 is located in the first foaming cavity 101. The guide structure 163 of the injection component 16 penetrates the side wall of the inner liner 12 and extends into the compartment 121, and penetrates the side wall of the partition 15. The guide structure 163 is provided with the aforementioned first snap-fit ​​structure 161 on the side away from the substrate 162. The guide structure 163 cooperates with the second snap-fit ​​structure 156 in the partition 15 through the first snap-fit ​​structure 161 to realize the snap-fit ​​connection between the injection component 16 and the partition 15, thereby realizing the pre-installation of the partition 15 on the inner liner 12 by the injection component 16 before foaming. Since the guide structure 163 forms a feeding channel 1631, one end of the feeding channel 1631 is connected to the first foaming cavity 101 and the other end of the feeding channel 1631 is connected to the second foaming cavity 102. After the foaming material is injected from the injection port on the outer shell 11, the foaming material first fills the first foaming cavity 101, and then flows into the second foaming cavity 102 in the partition 15 through the feeding channel 1631. After curing, a continuous heat insulation layer can be formed in the first foaming cavity 101 and the second foaming cavity 102.

[0244] Reference Figure 13 and Figure 14 The substrate 162 is firmly pressed onto the outer surface of the inner liner 12 to form a first-level sealing interface. The through-hole on the inner liner 12 and the through-hole on the partition 15 are the same in size and shape. The guide structure 163 is configured to conform to the outer contour of the through-hole on the inner liner 12 and the through-hole on the partition 15. The guide structure 163 and the through-hole on the partition 15 form an interference fit, so that the outer surface of the guide structure 163 and the through-hole on the inner liner 12 and the through-hole on the partition 15 form a second-level sealing interface. By using the first-level sealing interface and the second-level sealing interface, the gap between the injection part 16 and the inner liner 12 and the partition 15 is sealed as much as possible.

[0245] The refrigeration device 10 provided in this application embodiment forms a double sealing barrier through the sealing cooperation between the guide structure 163, the inner liner 12, and the partition 15, combined with the contact between the substrate 162 and the outer surface of the inner liner 12. This prevents the foaming material from overflowing from the gaps as much as possible, effectively mitigating the negative impact of foaming material leakage on the internal structure and appearance of the refrigeration device 10, enhancing the overall sealing performance of the refrigeration device 10, and maintaining the integrity and quality of the insulation layer.

[0246] In some embodiments, the refrigeration device 10 further includes fasteners.

[0247] Fasteners connect the injection molding part 16, the inner liner 12, and the partition 15.

[0248] Fasteners may include, but are not limited to, screws, pins, or rivets, and the embodiments of this application do not limit them.

[0249] As an example, the fastener can be a screw. At least one threaded hole can be opened on the base plate 162 of the injection part 16. The inner liner 12 can be opened with a threaded hole corresponding to the threaded hole on the base plate 162. The partition plate 15 can also be opened with a threaded hole corresponding to the threaded hole on the base plate 162. The fastener passes through the threaded hole of the injection part 16, the threaded hole of the inner liner 12 and the threaded hole of the partition plate 15 in sequence from the outside to the inside. The screw is tightened with the threaded hole of the injection part 16, the threaded hole of the inner liner 12 and the threaded hole of the partition plate 15 using a tooling to further reinforce the connection between the injection part 16, the inner liner 12 and the partition plate 15.

[0250] The refrigeration equipment 10 provided in this application embodiment, through the setting of the above-mentioned fasteners, directly connects the injection part 16, the inner liner 12 and the partition 15 into one body, forming a mechanical lock. On the basis of the clamping force of the first clamping structure 161 and the second clamping structure 156, the initial pre-tightening force before foaming is further enhanced. After the foamed material is cured to form a heat insulation layer, the clamping force, the fastening force and the heat insulation layer anchoring force work together to lock the inner liner 12, the injection part 16 and the partition 15 into one body as much as possible, further reducing the misalignment between the injection part 16, the inner liner 12 and the partition 15, and maximizing the stability and reliability of the refrigeration equipment 10 structure.

[0251] In some embodiments, refer to Figure 12 , Figure 15 , Figure 16 , Figure 18 and Figure 22 The inner liner 12 has a third snap-fit ​​structure 122 on its side wall. The third snap-fit ​​structure 122 is distributed separately from the injection part 16. The partition 15 has a fourth snap-fit ​​structure 1511 for snap-fitting with the third snap-fit ​​structure 122.

[0252] The third snap-fit ​​structure 122 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring. Correspondingly, the fourth snap-fit ​​structure 1511 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring that cooperate with the third snap-fit ​​structure 122. This application embodiment does not limit this.

[0253] As an example, refer to Figure 12 , Figure 15 , Figure 16 , Figure 18 and Figure 22 The inner liner 12 has a third snap-fit ​​structure 122 on both sides, and the partition 15 has a fourth snap-fit ​​structure 1511 at both ends in the left and right directions. The third snap-fit ​​structure 122 can be a slot, and the fourth snap-fit ​​structure 1511 can be a buckle.

[0254] Specifically, the buckle can be fixed, meaning its position cannot be visually changed. During assembly, slight deformation of the side wall of the metal inner liner 12 is required to achieve smooth locking between the fixed buckle and the slot. Using this type of fixed buckle can reduce the processing difficulty of the fourth snap-fit ​​structure 1511. Alternatively, the buckle can be telescopic, meaning it can retract inward when subjected to inward pressure and reset itself after the pressure is removed. During assembly, no deformation of the side wall of the metal inner liner 12 is required. The telescopic buckle can be smoothly locked between the telescopic buckle and the slot by utilizing its free telescopic characteristics. Using this type of telescopic buckle can reduce the assembly difficulty of the snap-fit ​​between the inner liner 12 and the partition 15.

[0255] The refrigeration equipment 10 provided in this application embodiment, through the cooperation of the third snap-fit ​​structure 122 of the inner liner 12 and the fourth snap-fit ​​structure 1511 of the partition 15, provides additional fixing points for the partition 15 on the basis of the snap-fit ​​between the injection part 16 and the partition 15, fixing the partition 15 from multiple directions and positions, providing initial positioning before foaming, minimizing the shaking or displacement of the partition 15 during the foaming process and use, optimizing the foaming effect, and enhancing the stability of the partition 15 installation.

[0256] In some embodiments, refer to Figure 11 and Figure 12 The back wall of the inner liner 12 is made of metal plate, and the back wall of the inner liner 12 is equipped with a filling part 16.

[0257] In other words, if the left and right sides of the inner liner 12 are made of metal plates, the back wall of the inner liner 12 is also made of metal plates.

[0258] The metal may include, but is not limited to, stainless steel or aluminum alloy, etc., and the embodiments of this application do not limit this.

[0259] Reference Figure 11 and Figure 12 Multiple injection components 16 are provided, and the multiple injection components 16 are distributed at intervals on the left side wall, right side wall and back wall of the inner liner 12. Here, multiple means two or more.

[0260] It is understandable that by adding a material injection component 16 to the back wall of the inner liner 12, on the one hand, the material injection component 16 on the back wall of the inner liner 12 and the material injection components 16 on the side walls of the inner liner 12 form a multi-point support system, constraining the displacement of the partition 15 from multiple directions. The material injection component 16 on the back wall of the inner liner 12 shares the longitudinal load of the partition 15, reduces the stress on the material injection components 16 on the side walls, and effectively alleviates the loosening or damage caused by excessive local stress. On the other hand, based on the original feeding channels 1631 distributed on both sides of the partition 15, a feeding channel 1631 distributed on the back of the partition 15 is added, which increases the feeding path of the partition 15 during the foaming process, reduces defects such as bubbles, voids or uneven thickness caused by poor material flow, and enables the foaming material to be evenly distributed inside the partition 15, thereby forming a continuous, uniform and dense insulation layer in the first foaming cavity 101 and the second foaming cavity 102, improving the quality of the insulation layer, and thus optimizing the insulation performance of the refrigeration equipment 10.

[0261] In some embodiments, refer to Figures 15 to 20 and Figure 22 The partition 15 includes a bottom shell 152 and a top cover 151 connected to each other. The top cover 151 covers the bottom shell 152. The top cover 151 is provided with a fifth snap-fit ​​structure 1512. The bottom shell 152 is provided with a sixth snap-fit ​​structure 1521 for snap-fitting with the fifth snap-fit ​​structure 1512.

[0262] The fifth snap-fit ​​structure 1512 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring. Correspondingly, the sixth snap-fit ​​structure 1521 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring that cooperate with the fifth snap-fit ​​structure 1512. This application embodiment does not limit this.

[0263] As an example, refer to Figures 15 to 20 and Figure 22 The fifth snap-fit ​​structure 1512 is a slot, and the sixth snap-fit ​​structure 1521 is a buckle.

[0264] The fifth snap-fit ​​structure 1512 and the sixth snap-fit ​​structure 1521 can be set one or multiple in a one-to-one correspondence, where multiple means two or more.

[0265] Among them, multiple fifth snap-fit ​​structures 1512 can be distributed on at least one side wall of the upper cover 151, and correspondingly, multiple sixth snap-fit ​​structures 1521 can be distributed on at least one side wall of the bottom shell 152. The specific arrangement depends on the actual needs, and this application embodiment does not limit it.

[0266] In this embodiment, refer to Figure 18 and Figure 20The upper cover 151 may include a top plate and multiple side plates connected to the top plate and joined end-to-end, making the bottom of the upper cover 151 open. The bottom shell 152 may include a bottom plate and multiple side plates connected to the bottom plate and joined end-to-end, making the top of the bottom shell 152 open. The upper cover 151 and the bottom shell 152 are fastened together by a fifth snap-fit ​​structure 1512 and a sixth snap-fit ​​structure 1521. The multiple side plates of the upper cover 151 are sleeved outside the multiple side plates of the bottom shell 152. The top plate of the upper cover 151 and the bottom plate of the bottom shell 152 are arranged opposite each other in the vertical direction, thus forming a second foaming cavity 102. Both the upper cover 151 and the bottom shell 152 may be provided with the aforementioned second snap-fit ​​structure 156, and the upper cover 151 may be provided with the aforementioned fourth snap-fit ​​structure 1511.

[0267] The refrigeration equipment 10 provided in this application embodiment is divided into a bottom shell 152 and an upper cover 151 by the above-mentioned partition 15, which can be manufactured and processed separately, reducing production difficulty and production cost. Combined with the design that the upper cover 151 and the bottom shell 152 are connected by a fifth snap-fit ​​structure 1512 and a sixth snap-fit ​​structure 1521, the assembly process of the partition 15 is simpler and faster, requiring no complicated tools and skills, reducing assembly time and labor costs.

[0268] In some embodiments, refer to Figures 18 to 20 The inner side wall of the top cover 151 is provided with a first hook 1513 protruding out, and at least a part of the side of the bottom shell 152 is inserted and engaged with the first hook 1513.

[0269] In this embodiment, refer to Figures 18 to 20 Each side wall of the upper cover 151 has a first hook 1513 protruding from its inner surface. The first hook 1513 forms a downward-open hanging interface. When assembling the partition 15, the multiple sides of the bottom shell 152 are gradually inserted into the hanging interfaces of the first hook 1513 on the multiple side walls of the upper cover 151. After being inserted into place, the fifth snap-fit ​​structure 1512 of the upper cover 151 and the sixth snap-fit ​​structure 1521 of the bottom shell 152 are locked together.

[0270] The refrigeration device 10 provided in this application embodiment, through the connection design of at least a portion of the side of the bottom shell 152 being inserted into the first hook 1513 of the top cover 151, combined with the snap-fit ​​of the aforementioned fifth snap-fit ​​structure 1512 and sixth snap-fit ​​structure 1521, further increases the connection strength between the bottom shell 152 and the top cover 151, further enhances the load-bearing capacity and stability of the partition 15, and at the same time makes at least one side of the bottom shell 152 tightly fitted with the corresponding side wall of the top cover 151, thereby improving the docking accuracy of the top cover 151 and the bottom shell 152, and thus optimizing the sealing performance of the partition 15.

[0271] In some embodiments, refer to Figure 18 , Figure 20 and Figure 24The inner top wall of the upper cover 151 is provided with a first positioning element 1514, and the inner bottom wall of the bottom shell 152 is provided with a second positioning element 1522 for positioning and cooperating with the first positioning element 1514.

[0272] The first positioning element 1514 may include, but is not limited to, a protrusion, a groove 1811, or a hole, and the second positioning element 1522 may include, but is not limited to, a protrusion, a groove 1811, or a hole that matches the first positioning element 1514. This application embodiment does not limit this.

[0273] The first positioning element 1514 and the second positioning element 1522 can be set one or multiple elements can be set separately in a one-to-one correspondence, where multiple means two or more.

[0274] The refrigeration device 10 provided in this application embodiment provides a precise positioning reference for the assembly of the upper cover 151 and the bottom shell 152 through the positioning cooperation of the first positioning member 1514 and the second positioning member 1522. This effectively solves the problems of deformation of the partition 15 and poor sealing caused by assembly deviation, thereby effectively reducing the errors that may occur during manual assembly, thereby improving the assembly quality and consistency of the partition 15. At the same time, it fixes the relative position of the upper cover 151 and the bottom shell 152, reducing the relative movement or misalignment of the upper cover 151 and the bottom shell 152 during use, thereby maintaining the overall structural stability of the partition 15.

[0275] In some embodiments, refer to Figure 18 , Figure 20 and Figure 24 The first positioning member 1514 is sleeved and connected to the second positioning member 1522. The first positioning member 1514 is provided with a seventh snap-fit ​​structure 15141, and the second positioning member 1522 is provided with an eighth snap-fit ​​structure 15221 for snap-fitting with the seventh snap-fit ​​structure 15141.

[0276] In this embodiment, refer to Figure 18 and Figure 20 The first positioning element 1514 can be designed as a sleeve, and the second positioning element 1522 can also be designed as a sleeve. The dimensions of the first positioning element 1514 and the second positioning element 1522 are different. Specifically, one of the first positioning element 1514 and the second positioning element 1522 can be sleeved over the other, in which case the size of the outer positioning element is larger than the size of the inner positioning element. For example, refer to... Figure 24The first positioning element 1514 is fitted over the second positioning element 1522. During the fastening process of the upper cover 151 and the bottom shell 152, one of the first positioning element 1514 and the second positioning element 1522 gradually extends into the other. During the fitting process, the seventh snap-fit ​​structure 15141 on the first positioning element 1514 and the eighth snap-fit ​​structure 15221 on the second positioning element 1522 engage, so that the first positioning element 1514 and the second positioning element 1522 are assembled in place.

[0277] The seventh snap-fit ​​structure 15141 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring. Correspondingly, the eighth snap-fit ​​structure 15221 may include, but is not limited to, a snap fastener, a snap hook, a snap tooth, a hook, a protrusion, a slot, or a hanging ring that cooperate with the seventh snap-fit ​​structure 15141. This application embodiment does not limit this.

[0278] As an example, refer to Figure 18 , Figure 20 and Figure 24 The first positioning element 1514 is sleeved outside the second positioning element 1522, the seventh snap-fit ​​structure 15141 is a slot, and the eighth snap-fit ​​structure 15221 is a buckle that protrudes outward and is set on the outer wall of the second positioning element 1522.

[0279] The seventh snap-fit ​​structure 15141 and the eighth snap-fit ​​structure 15221 can be set one or multiple in a one-to-one correspondence, where multiple means two or more.

[0280] The refrigeration device 10 provided in this application embodiment, through the above-mentioned seventh snap-fit ​​structure 15141 and eighth snap-fit ​​structure 15221, provides initial positioning and fixation by connecting the first positioning member 1514 and the second positioning member 1522. The snap-fit ​​cooperation between the seventh snap-fit ​​structure 15141 and the eighth snap-fit ​​structure 15221 further enhances the connection between the upper cover 151 and the bottom shell 152, which can effectively prevent the partition 15 from accidentally separating due to vibration or other reasons during transportation or use, thereby improving the reliability and stability of the refrigeration device 10.

[0281] In some embodiments, refer to Figure 9 , Figure 10 , Figure 18 , Figure 20 and Figure 23 The inner top wall of the upper cover 151 is provided with a first enclosure 1515, and the inner bottom wall of the bottom shell 152 is provided with a second enclosure 1523. The first enclosure 1515 and the second enclosure 1523 are connected to form a vent 154, so that the storage spaces 1211 located on both sides of the partition 15 are interconnected through the vent 154 and are separated from the first foaming cavity 101.

[0282] In this embodiment, refer to Figure 9 , Figure 10 , Figure 18 and Figure 20 Both the first enclosure member 1515 and the second enclosure member 1523 can be designed as annular protrusions. One of the first enclosure member 1515 and the second enclosure member 1523 is provided with an annular insertion groove, and the other is inserted into the annular insertion groove. For example, refer to Figure 23 The first enclosure 1515 is provided with a downward-opening annular insertion groove, and the second enclosure 1523 is directly inserted upward into the annular insertion groove of the first enclosure 1515. The first enclosure 1515 and the second enclosure 1523 are coupled together to define the internal ventilation opening 154. Furthermore, the portion of the ventilation opening 154 near the storage space 1211 can be designed with an flared opening. Specifically, the main body of the ventilation opening 154 has a constant vertical dimension, while the portion of the ventilation opening 154 near the upper storage space 1211 gradually increases in size from bottom to top, and the portion of the ventilation opening 154 near the lower storage space 1211 gradually increases in size from top to bottom. Using this flared opening design can reduce the wind resistance when the gas enters and leaves the ventilation opening 154 to a certain extent.

[0283] The refrigeration device 10 provided in this application embodiment has a structural design that forms a vent 154 by connecting the first enclosure 1515 and the second enclosure 1523. The storage spaces 1211 located on both sides of the partition 15 can be interconnected through the vent 154, which helps cold air to flow freely between the various storage spaces 1211, reduces temperature differences, and improves the temperature uniformity of the entire refrigeration device 10. In addition, during the assembly process, the formation of the vent 154 and the assembly of the partition 15 can be completed simply by inserting the upper cover 151 and the bottom shell 152. The structural design is simple, the assembly method is convenient and quick, reduces production costs and manufacturing difficulty, and also improves production efficiency.

[0284] In some embodiments, refer to Figures 15 to 17 and Figure 25 The partition 15 also includes a front baffle 153 installed on the front side of the upper cover 151, and the refrigeration device 10 also includes a frame 13.

[0285] The opening frame 13 is installed on the open side of the inner liner 12. The opening frame 13 is connected between the outer shell 11 and the inner liner 12. The opening frame 13 is provided with a relief groove 131. Both ends of the front baffle 153 extend through the relief groove 131 to connect with the outer shell 11.

[0286] It should be noted that, in order to reduce the formation of condensation, heat insulation material is provided on the front side of the upper cover 151. The heat insulation material includes, but is not limited to, sponge, felt, etc. The front surface of the upper cover 151 can be provided with a corresponding limiting structure to reduce the displacement of the heat insulation material. In order to cover the heat insulation material, a front baffle 153 is added on the front side of the heat insulation material.

[0287] In this embodiment, refer to Figure 25 The end of the front baffle 153 can be inserted into the clearance groove 131 of the mouth frame 13, so that the front baffle 153 will not protrude forward from the mouth frame 13, and the end of the front baffle 153 can be bent backward. The outer shell 11 can form a jaw to hold the bent part and part of the mouth frame 13, so that the front baffle 153 will not protrude forward from the outer shell 11.

[0288] The refrigeration device 10 provided in this application embodiment, through the cooperative design of the front baffle 153, the frame 13 and the outer shell 11, can seal normally between the door and the frame 13 when the door of the refrigeration device 10 is closed, without interference caused by the protrusion of the front baffle 153, thereby maintaining the basic sealing performance between the frame 13 and the door. At the same time, since the end of the front baffle 153 is embedded with the relief groove 131, the cooperation between the frame 13 and the outer shell 11 and the front baffle 153 is more coordinated, making the lines of the refrigeration device 10 smoother, the appearance of the refrigeration device 10 more refined and flat, and improving the overall aesthetics of the refrigeration device 10.

[0289] In some embodiments, refer to Figure 26 and Figure 27 The front baffle 153 is embedded between the bottom shell 152 and the top cover 151, and the rear wall of the front baffle 153 is provided with a plurality of fourth hooks 1531. The front side of the top cover 151 is provided with a first hook interface 1517 for cooperating with some of the fourth hooks 1531, and the front side of the bottom shell 152 is provided with a second hook interface 1525 for cooperating with another part of the fourth hooks 1531.

[0290] In this context, "multiple" refers to two or more hooks. The orientation of the hooks of the multiple fourth hooks 1531 can include, but is not limited to, left, right, top, or bottom. This application embodiment does not impose any restrictions on this.

[0291] In this embodiment, refer to Figure 26 and Figure 27After the bottom shell 152 and the top cover 151 are assembled, a groove can be defined on the front side of the bottom shell 152 and the top cover 151. The front baffle 153 can be embedded in the groove. Multiple fourth hooks 1531 can be spaced apart on the upper part of the rear wall of the front baffle 153. Multiple first hook interfaces 1517 can be spaced apart on the corresponding position of the top cover 151. The multiple fourth hooks 1531 on the upper part of the rear wall of the front baffle 153 extend into the multiple first hook interfaces 1517 of the top cover 151 one by one. Multiple fourth hooks 1531 can be spaced apart on the lower part of the rear wall of the front baffle 153. Multiple second hook interfaces 1525 can be spaced apart on the corresponding position of the bottom shell 152. The multiple fourth hooks 1531 on the lower part of the rear wall of the front baffle 153 extend into the multiple second hook interfaces 1525 of the bottom shell 152 one by one. If the front baffle 153 is moved forward due to external disturbance, the hooks of the multiple second hooks 1516 can abut against the outer periphery of the multiple first hook interfaces 1517 and the multiple second hook interfaces 1525 to limit the excessive movement of the front baffle 153.

[0292] The refrigeration device 10 provided in this application embodiment, through the cooperative design of the fourth hook 1531 with the first hook interface 1517 and the second hook interface 1525, combined with the structural design of the front baffle 153 being embedded between the bottom shell 152 and the top cover 151, achieves the limiting assembly of the front baffle 153 with the top cover 151 and the bottom shell 152, improves the reliability and stability of the installation of the front baffle 153, and effectively resists the loosening or falling off of the front baffle 153 caused by external forces. At the same time, the design of the first hook interface 1517 and the second hook interface 1525 enables the front baffle 153 to be quickly and accurately positioned during installation, reducing installation deviation.

[0293] In some embodiments, refer to Figure 18 , Figure 20 and Figure 23 The partition 15 includes a plurality of protruding ribs 155 that are spaced apart from each other and protruding from the inner wall. The ribs 155 are used to anchor the insulation layer in the second foaming cavity 102.

[0294] "Multiple" here means two or more. The shape of the raised rib 155 can be designed as a straight line, a bend, a wave, or a cross, etc., and the embodiments of this application do not limit this.

[0295] As an example, refer to Figure 18 , Figure 20 and Figure 23 The shape of the rib 155 can be designed as a bend, specifically, the rib 155 can be U-shaped.

[0296] Furthermore, referring to Figure 18 , Figure 20 and Figure 23Multiple ribs 155 can be provided on the inner wall of the bottom shell 152 and the inner wall of the top cover 151. The specific distribution of the multiple ribs 155 on the bottom shell 152 and the top cover 151 can be designed according to the stress condition of the partition 15, the size of the partition 15 and other related factors. This application embodiment does not limit this.

[0297] The refrigeration equipment 10 provided in this application embodiment increases the bonding strength between the partition 15 and the insulation layer by setting the above-mentioned multiple ribs 155 and utilizing the mechanical anchoring effect of the multiple ribs 155. During the curing process of the foamed material, the multiple ribs 155 can be embedded in the insulation layer as anchor points, increasing the contact area and friction between the partition 15 and the insulation layer, reducing the separation of the insulation layer from the partition 15 due to vibration, temperature changes, etc. during use, thereby effectively maintaining the long-term stability and insulation performance of the insulation layer.

[0298] In some embodiments, refer to Figure 17 , Figure 18 and Figure 20 The bottom shell 152 includes a first shell 152a and a second shell 152b covering the first shell 152a, and the top cover 151 includes a first cover 151a and a second cover 151b covering the first cover 151a. The first shell 152a and the first cover 151a are made of plastic, and the second shell 152b and the second cover 151b are made of metal.

[0299] In this embodiment, refer to Figure 17 , Figure 18 and Figure 20 The first cover 151a is provided with the aforementioned fourth snap-fit ​​structure 1511, and the second shell 152b is provided with a through hole to avoid the fourth snap-fit ​​structure 1511. The first cover 151a is also provided with the aforementioned second snap-fit ​​structure 156, first positioning member 1514, first hook 1513, first enclosure member 1515 and protruding rib 155, and the first shell 152a is provided with the aforementioned second snap-fit ​​structure 156, second positioning member 1522, fourth hook 1531, second enclosure member 1523 and protruding rib 155.

[0300] Understandably, metal stamping processes are subject to significant limitations when forming complex curved surfaces or small features, resulting in high processing difficulty and mold costs, which negatively impacts production efficiency and costs. Even when a connecting structure is stamped out, the resulting connecting structure with sharp corners or deep drawing features is prone to defects such as springback and wrinkling. Therefore, this application sets all the complex and small connecting structures on the first cover 151a and the first shell 152a made of plastic material. It can use injection molding, extrusion and other processes to achieve one-time forming of complex curved surfaces and small connecting structures, breaking through the geometric limitations of metal stamping, thereby significantly improving the stability and precision of the partition 15 assembly. Furthermore, plastic materials are prone to cracking, discoloration, and yellowing after prolonged use. They also tend to absorb food odors and may be difficult to clean after long-term use. In addition, plastic materials do not have adequate antibacterial properties, making them difficult to clean. In order to maintain consistency with the appearance of the metal inner liner 12 and enhance the visual appeal of the product, the first shell 152a and the first cover 151a, which are exposed to the user's view to form the appearance of the partition 15 and come into contact with the stored items, are made of metal materials through a stamping process. This optimizes the antibacterial properties of the entire refrigeration equipment 10 and reduces the difficulty of cleaning.

[0301] In some embodiments, refer to Figure 18 and Figure 19 The inner side of the second cover 151b is provided with a second hook 1516, which is formed by a bendable piece and is used to engage with the side of the first cover 151a.

[0302] In actual implementation, refer to Figure 18 and Figure 19 The second hook 1516 can be formed by the bendable piece in the following way: The second cover 151b may include a second cover body and a bendable piece extending downward from the edge of the second cover 151b body. After the second cover body is attached to the outside of the first cover 151a, the bendable piece can be bent inward and upward by tooling or manual bending until it abuts against the bottom wall and inner side wall of the side of the first cover 151a to form the second hook 1516, thereby fixing the second cover 151b to the first cover 151a by the second hook 1516.

[0303] One or more second hooks 1516 can be provided. Multiple second hooks 1516 can be connected to multiple sides of the second cover body. Multiple second hooks 1516 can be connected to each side of the second cover body. Multiple second hooks 1516 can be inserted and connected to multiple sides of the first cover 151a. Here, "multiple" means two or more.

[0304] The refrigeration device 10 provided in this application embodiment, through the setting of the second hook 1516 and the assembly design of the second hook 1516 formed by a bendable piece, achieves stable coverage of the first cover 151a by the second cover 151b. The second hook 1516 is hidden inside the partition 15 and is not exposed to the user's view, so that the first cover 151a has a continuous, complete and flat outer surface, thereby improving the aesthetics of the internal space of the refrigeration device 10. Moreover, the assembler does not need complicated tools and cumbersome operation steps. He only needs to bend the bendable piece and hook it to the corresponding side to complete the assembly between the first cover 151a and the second cover 151b, which reduces the assembly difficulty and cost and improves the assembly efficiency of the upper cover 151.

[0305] In some embodiments, refer to Figure 20 and Figure 21 The inner side of the second shell 152b is provided with a third hook 1524, which is formed by a bendable piece and is used to engage with the side of the first shell 152a.

[0306] In actual implementation, refer to Figure 20 and Figure 21 The third hook 1524 formed by the bendable piece can be achieved in the following way: the second shell 152b may include a second shell body and a bendable piece extending upward from the edge of the second shell 152b body. After the second shell body is attached to the outside of the first shell 152a, the bendable piece can be bent to abut against the side of the first shell 152a by tooling or manual means to form the third hook 1524, thereby enabling the second shell 152b to be fixed to the first shell 152a by the third hook 1524.

[0307] One or more third hooks 1524 can be provided. Multiple third hooks 1524 can be connected to multiple sides of the second shell body. Multiple third hooks 1524 can be connected to each side of the second shell body. Multiple third hooks 1524 can be plugged into multiple sides of the first shell 152a. Here, "multiple" means two or more.

[0308] The refrigeration device 10 provided in this application embodiment, through the setting of the third hook 1524 and the assembly design of the third hook 1524 formed by the bendable piece, achieves stable coverage of the first shell 152a by the second shell 152b. The third hook 1524 is hidden inside the partition 15 and is not exposed to the user's view, so that the first shell 152a has a continuous, complete and flat outer surface, thereby improving the aesthetics of the internal space of the refrigeration device 10. Moreover, the assembler does not need complicated tools and cumbersome operation steps. He only needs to bend the bendable piece and hook it to the corresponding side to complete the assembly between the first shell 152a and the second shell 152b, which reduces the assembly difficulty and cost and improves the assembly efficiency of the bottom shell 152.

[0309] In some embodiments, refer to Figure 22 The first cover 151a is provided with a fifth snap-fit ​​structure 1512, the first shell 152a is provided with a sixth snap-fit ​​structure 1521, and the second shell 152b is provided with a ninth snap-fit ​​structure 1526. The sixth snap-fit ​​structure 1521 is snap-fitted with the fifth snap-fit ​​structure 1512 and the ninth snap-fit ​​structure 1526.

[0310] The fifth snap-fit ​​structure 1512 may include, but is not limited to, a snap-fit, a snap-fit, a snap-fit ​​tooth, a hook, or a protrusion. Correspondingly, the sixth snap-fit ​​structure 1521 may include, but is not limited to, a slot or a hanging ring that cooperates with the fifth snap-fit ​​structure 1512. The ninth snap-fit ​​structure 1526 may include, but is not limited to, a slot or a hanging ring that cooperates with the fifth snap-fit ​​structure 1512. This application embodiment does not limit this.

[0311] For example, in this embodiment, refer to Figure 22 The fifth snap-fit ​​structure 1512 and the ninth snap-fit ​​structure 1526 are both snap-fit ​​slots, while the sixth snap-fit ​​structure 1521 is a snap-fit.

[0312] It should be noted that, with Figure 20 and Figure 21 For example, the third hook 1524 can be set on the front side of the second shell 152b, that is, the front side of the second shell 152b is inserted and engaged with the front side of the first shell 152a through the third hook 1524. The ninth snap-fit ​​structure 1526 can be set on the wall surface of the second shell 152b where the third hook 1524 is not set, that is, the ninth snap-fit ​​structure 1526 can be set on the left side wall, the right side wall and the back wall. Correspondingly, the sixth snap-fit ​​structure 1521 can also be set outwardly on the left side wall, the right side wall and the back wall.

[0313] When assembling the partition 15, the first cover 151a and the second cover 151b are first assembled into the upper cover 151, and the first shell 152a and the second shell 152b are assembled into the bottom shell 152. At this time, the sixth snap-fit ​​structure 1521 of the first shell 152a is snapped into the ninth snap-fit ​​structure 1526 of the second shell 152b, and the sixth snap-fit ​​structure 1521 still protrudes outward relative to the ninth snap-fit ​​structure 1526. During the process of fastening the upper cover 151 and the bottom shell 152, the sixth snap-fit ​​structure 1521 of the first shell 152a continues to snap into the fifth snap-fit ​​structure 1512 of the first cover 151a while being locked with the ninth snap-fit ​​structure 1526 of the second shell 152b. This achieves simultaneous snap-fit ​​connection between the first shell 152a, the second shell 152b, and the first cover 151a, thereby reducing the number of snap-fit ​​structures used and thus reducing the processing difficulty and production cost.

[0314] This application discloses a refrigeration device 10.

[0315] It should be noted that the refrigeration equipment 10 in this embodiment includes, but is not limited to, refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines, etc. The refrigeration equipment 10 has a variety of structural forms and a wide range of applications.

[0316] The following is for reference. Figures 28-35 A refrigeration device 10 according to an embodiment of this application is described.

[0317] In some embodiments, refer to Figures 28 to 30 The refrigeration equipment 10 includes: an outer shell 11, an inner liner 12, an insulation layer, an embedded part 18, a vertical beam base 17, and a connector 191.

[0318] The inner liner 12 is installed inside the outer shell 11, forming a compartment 121 open on one side, and the top wall of the inner liner 12 is a metal plate; the door is used to open or close the compartment 121, and the door is provided with a vertically extending and pivotable vertical beam; an insulation layer is formed at least between the outer shell 11 and the inner liner 12; an embedded part 18 is provided between the outer shell 11 and the inner liner 12, the embedded part 18 is installed on the outer top wall of the inner liner 12, and the embedded part 18 is embedded in the insulation layer; the vertical beam base 17 is used to cooperate with the vertical beam of the door of the refrigeration equipment 10, the vertical beam base 17 is installed on the inner top wall of the inner liner 12, and a part of the vertical beam base 17 passes through the inner liner 12 and extends into the embedded part 18; the connector 191 connects the embedded part 18, the inner liner 12 and the vertical beam base 17.

[0319] In other words, at least the top wall of the inner liner 12 used for mounting the vertical beam base 17 is a metal plate.

[0320] The metal may include, but is not limited to, stainless steel or aluminum alloy, etc., and the embodiments of this application do not limit this.

[0321] The embedded part 18 is used to match the shape of the vertical beam base 17 and help fix the vertical beam base 17 to the inner liner 12. Due to the large processing difficulty of the complex shape of metal materials and the difficulty in controlling the processing accuracy, the embedded part 18 can be made of non-metallic materials such as plastic, composite materials or ceramics.

[0322] For example, considering factors such as material cost, processing difficulty, and structural strength, the embedded part 18 is made of plastic and formed through processes such as injection molding. The plastic material may include, but is not limited to, ABS (Acrylonitrile Butadiene Styrene), PU (Polyurethane), PS (Polystyrene), or HIPS (High Impact Polystyrene), etc., and this embodiment does not impose any limitations on this.

[0323] The connector 191 may include, but is not limited to, screws, bolts, rivets, snap-fit ​​components, or pins, and the embodiments of this application do not limit this.

[0324] One or more connectors 191 can be provided, and multiple connectors 191 are distributed at intervals. Here, multiple means two or more, and the specific number depends on the actual needs. This application embodiment does not limit this.

[0325] In actual implementation, refer to Figure 29 and Figure 30 The assembly of the vertical beam base 17 can be achieved as follows: Before forming the insulation layer, a pre-embedded part 18 is pre-installed between the outer top wall of the inner liner 12 and the outer shell 11, and the vertical beam base 17 is installed at the corresponding position on the inner top wall of the inner liner 12, so that the connection positions of the pre-embedded part 18, the inner liner 12 and the vertical beam base 17 are aligned. After alignment, the pre-embedded part 18, the inner liner 12 and the vertical beam base 17 are fixed by the connector 191, thus completing the assembly of the pre-embedded part 18 and the vertical beam base. After the initial assembly of the top wall of the inner liner 12, foaming can begin. The foaming material is injected from the injection port on the outer shell 11, expands and fills the space between the inner liner 12 and the outer shell 11, thereby wrapping the injection part 16. After curing, a continuous insulation layer is formed, allowing the embedded part 18 to be embedded in the insulation layer. Under the anchoring force of the insulation layer, the injection part 16 is securely fixed to the outer top wall of the inner liner 12, thereby securely fixing the vertical beam base 17 to the inner top wall of the inner liner 12.

[0326] Understandably, if the conventional installation scheme of the existing vertical beam base 17 is adopted, the top wall of the metal inner liner 12 needs to be manufactured by stamping to create grooves, protrusions, or complex mating surfaces that match the vertical beam base 17. However, the ductility of metal materials is limited, and complex shapes can easily lead to complex processes, mold wear, and excessively high scrap rates. On the one hand, this application provides an embedded part 18 on the outer top wall of the inner liner 12. Since a part of the vertical beam base 17 passes through the inner liner 12 and extends into the embedded part 18, the embedded part 18 can replace the inner liner 12 to adapt to the shape of the vertical beam base 17. Specifically, taking the embedded part 18 as an example, if the embedded part 18 is made of plastic, the inner liner 12 only needs to be cut with clearance holes. Complex shapes can be achieved by the plastic embedded part 18 through injection molding and other processes, thus avoiding the process bottleneck of deep drawing and forming the installation groove of the metal vertical beam base 17 in the traditional scheme. This significantly reduces production costs and improves production efficiency. On the other hand, based on the connection of connector 191, the foamed material solidifies to form a rigid whole, tightly wrapping the embedded part 18, so that the embedded part 18 is tightly attached to the inner liner 12 under the anchoring force of the insulation layer. In addition, when plastic embedded part 18 is used, the plastic material can better adhere to the foamed material, further increasing the bonding strength between the insulation layer and the embedded part 18. Even if it is subjected to the door opening and closing load for a long time, the embedded part 18 is not easy to loosen or shift.

[0327] The refrigeration equipment 10 provided in this application embodiment, through the assembly design of the aforementioned embedded part 18, inner liner 12 and vertical beam base 17, the embedded part 18 replaces the top wall of the metal inner liner 12 to form a complex shape that fits the vertical beam base 17. The top wall of the inner liner 12 only needs to be cut to make room, which breaks through the limitations of metal plates when forming complex curved surfaces or small features, significantly reduces the processing difficulty and processing cost, and greatly improves production efficiency. At the same time, combined with the integrated locking design of the connector 191 for the embedded part 18, inner liner 12 and vertical beam base 17, and the anchoring of the insulation layer, the embedded part 18 is firmly fixed to the top wall of the inner liner 12, which significantly reduces the risk of the embedded part 18 loosening and shifting under the long-term load of door opening and closing, thereby increasing the bonding strength between the embedded part 18, inner liner 12 and vertical beam base 17, and thus improving the reliability and stability of the installation of the vertical beam base 17.

[0328] In some embodiments, refer to Figure 29 , Figure 32 , Figure 34 and Figure 35 The vertical beam base 17 includes an upwardly protruding first protrusion 1711, which forms a guide groove 17111 for cooperating with the vertical beam. The guide groove 17111 is open to the front and the bottom. The inner liner 12 is provided with a first opening 125 for avoiding the first protrusion 1711. The embedded part 18 includes an upwardly protruding second protrusion 181, which is disposed opposite to the first opening 125. The second protrusion 181 forms a groove 1811 for accommodating part of the first protrusion 1711.

[0329] At the position on the top wall of the inner liner 12 corresponding to the installation position of the vertical beam base 17, a first opening 125 can be cut out using a cutting device. The shape and size of the first opening 125 need to be precisely designed to fit the subsequent installation of the first protrusion 1711 on the vertical beam base 17.

[0330] Before the inner liner 12 is installed into the outer shell 11, the embedded part 18 needs to be accurately placed on the outer top wall of the inner liner 12 so that the second protrusion 181 is opposite to the first opening 125 on the inner liner 12. The position of the embedded part 18 can be initially fixed on the inner liner 12 by means of adhesive or mechanical positioning.

[0331] To ensure precise alignment between the vertical beam and the vertical beam base 17 during the opening and closing of the door, the vertical beam base 17 needs to be machined with an upwardly protruding first protrusion 1711. A guide groove 17111 can be formed on the inner side of the first protrusion 1711, opening forward and downward to facilitate the smooth insertion and rotation guidance of the vertical beam. To accommodate the shape of the first protrusion 1711, the embedded part 18 needs to be machined with a second protrusion 181. The shape and size of the second protrusion 181 can be designed to match the shape and size of the portion of the first protrusion 1711 extending beyond the opening of the inner liner 12, so that the groove 1811 formed on the inner side of the second protrusion 181 can properly accommodate the portion of the first protrusion 1711 extending beyond the opening of the inner liner 12 without causing interference between the first protrusion 1711 and the second protrusion 181. In addition, while the second protrusion 181 forms a groove 1811 to fit the shape of the first protrusion 1711, it also completely isolates the first protrusion 1711 from the insulation layer, reducing the probability of the vertical beam base 17 becoming loose due to the expansion force of the foaming material squeezing the second protrusion 181 during the foaming process.

[0332] The refrigeration device 10 provided in this application embodiment has a structural design in which the second protrusion 181 of the pre-embedded part 18 forms a groove 1811 to accommodate the first protrusion 1711 of the vertical beam base 17. This design achieves shape adaptation of the pre-embedded part 18 to the part of the vertical beam base 17 that extends out of the inner liner 12. The inner liner 12 only needs to be machined with an opening to avoid the first protrusion 1711. Under the premise of isolating the first protrusion 1711 and the insulation layer, the groove 1811 formed by the second protrusion 181 can also provide precise guidance, which helps the first protrusion 1711 of the vertical beam base 17 to be accurately inserted, thereby improving the ease of installation of the vertical beam base 17.

[0333] In some embodiments, refer to Figure 31 , Figure 32 and Figure 35 The bottom of the second protrusion 181 is provided with a positioning protrusion 182 spaced apart from the first protrusion 1711, and the positioning protrusion 182 passes through the first opening 125.

[0334] The positioning protrusion 182 is used to position and engage with the first opening 125 of the inner liner 12 during the installation of the embedded part 18. One or more positioning protrusions 182 may be provided; "multiple" means two or more.

[0335] The positioning protrusion 182 can be designed as a block, strip, ring, or irregular shape, etc., and the embodiments of this application do not limit it.

[0336] The fit between the positioning protrusion 182 and the first opening 125 can be a transition fit, an interference fit, or a clearance fit, and this application embodiment does not limit this.

[0337] The protrusion height of the positioning protrusion 182 can be designed according to relevant factors such as the thickness of the inner liner 12 and the height of the first protrusion 1711, and this embodiment of the application does not limit this.

[0338] The refrigeration equipment 10 provided in this application embodiment, through the setting of the positioning protrusion 182, extends into the first opening 125, providing a clear positioning reference for the embedded part 18 and the inner liner 12. The embedded part 18 can be accurately positioned during installation, so that the embedded part 18 can be precisely aligned with the vertical beam base 17, reducing mutual interference between the embedded part 18 and the vertical beam base 17 due to positional deviation, significantly improving the installation accuracy of the embedded part 18 and the vertical beam base 17. Furthermore, during the assembly process, it is only necessary to align the positioning protrusion 182 with the first opening 125 and insert it, without the need for complex measurement and adjustment steps, thereby reducing the installation difficulty, reducing the installation time, and thus improving the assembly efficiency.

[0339] In some embodiments, refer to Figure 31 , Figure 32 and Figure 35 The positioning protrusion 182 is a ring structure, and the positioning protrusion 182 abuts against the side wall of the first opening 125, and the positioning protrusion 182 is set in the same shape as the outer contour of the first opening 125.

[0340] Specifically, the positioning protrusion 182 can be, but is not limited to, a square ring, a circular ring, or an irregular ring, etc., and the embodiments of this application do not limit this.

[0341] Understandably, the positioning protrusion 182 adopts an annular structure that conforms to the outer contour of the first opening 125, and the outer wall of the positioning protrusion 182 abuts against the side wall of the first opening 125. This design provides the mounting base 193 with a comprehensive and tight positioning method. The annular structure can limit the embedded part 18 from multiple directions, effectively reducing the loosening or displacement of the embedded part 18 during the foaming process or use, and improving the overall reliability of the refrigeration equipment 10 structure. At the same time, since the positioning protrusion 182 and the first opening 125 are sealed together, the probability of gaps between the positioning protrusion 182 and the first opening 125 is minimized, significantly reducing the risk of foam material overflowing from gaps or condensate leaking from gaps, thereby enhancing the sealing performance and antibacterial performance of the inner liner 12.

[0342] In some embodiments, refer to Figure 32 The edge of the embedded part 18 is sealed to the outer periphery of the first opening 125.

[0343] The sealing method between the edge of the embedded part 18 and the outer periphery of the first opening 125 may include, but is not limited to, elastic sealing ring sealing, sealing film heat sealing, liquid sealant bonding, sealing tape application, hot melt sealing or sealing gasket sealing, etc., and the embodiments of this application do not limit this.

[0344] The sealing material may include, but is not limited to, PE (Polyethylene) film, silicone rubber, or polyurethane elastomer, etc., and the embodiments of this application do not limit this.

[0345] The area of ​​the sealing interface between the edge of the embedded part 18 and the outer periphery of the first opening 125 can be customized according to actual needs, and this embodiment does not limit this.

[0346] The refrigeration equipment 10 provided in this application embodiment, through the structural design of the sealing fit between the edge of the aforementioned embedded part 18 and the outer periphery of the first opening 125, effectively prevents the foaming material from overflowing through the gap between the embedded part 18 and the inner liner 12, so that the foaming material can only fill within the predetermined space, maintaining the integrity and uniformity of the insulation layer, effectively alleviating the local decrease in insulation performance caused by the overflow of foaming material, and at the same time preventing condensate from seeping into the insulation layer through the gap between the embedded part 18 and the inner liner 12, thereby significantly reducing the corrosion rate of the inner liner 12, effectively reducing mold growth, and thus maximizing the sealing performance and antibacterial performance of the inner liner 12.

[0347] In some embodiments, refer to Figures 28 to 30 , Figure 32 and Figure 33 The refrigeration equipment 10 also includes: a frame 13.

[0348] The mouth frame 13 is installed on the open side of the inner liner 12. The mouth frame 13 is connected between the outer shell 11 and the inner liner 12. The vertical beam base 17 is installed on the front side of the mouth frame 13. The inner side of the mouth frame 13 is provided with a second opening 133 that communicates with the first opening 125. The second opening 133 is used to avoid the first protrusion 1711.

[0349] At the installation position of the first protrusion 1711 of the vertical beam base 17 corresponding to the frame 13, a second opening 133 can be cut out using a cutting device. The size of the second opening 133 needs to be designed to match the size of the first part so that the first protrusion 1711 of the vertical beam base 17 can pass smoothly through the frame 13 without interference, thereby adapting to the subsequent installation of the first protrusion 1711 on the vertical beam base 17.

[0350] The second opening 133 is connected to the first opening 125, and a portion of the second opening 133 is positioned opposite to the first opening 125. In other words, the projections of the first opening 125 and the second opening 133 in the vertical direction overlap. Thus, by utilizing the positions of the first opening 125 and the second opening 133, structural support is provided for a portion of the first protrusion 1711 to pass through the frame 13 and the inner liner 12 and enter the groove 1811 of the embedded part 18.

[0351] Furthermore, in the design and manufacturing of some refrigeration equipment 10, due to comprehensive considerations of output requirements, product consistency, and production costs, the frame 13 can be manufactured using plastic material through extrusion molding. However, since extrusion molding is suitable for manufacturing continuous profiles with simple shapes and consistent cross-sectional shapes, it is difficult to process complex shapes. This application provides an embedded part 18 on the outer top wall of the inner liner 12, with a portion of the vertical beam base 17 passing through the frame 13 and extending into the embedded part 18. In this way, the embedded part 18 can replace metal plates and / or extruded parts to adapt to the shape of the vertical beam base 17. The top wall of the inner liner 12 and the inner wall of the frame 13 only need to be cut to make room, breaking through the limitations of metal plates and extruded parts when forming complex curved surfaces or small features. This removes the strict restrictions on the manufacturing process of the frame 13, increases the flexibility and applicability of the refrigeration equipment 10, and achieves cost control.

[0352] In addition, since the vertical beam base 17 is installed on the front side of the frame 13, and the frame 13 provides an additional installation base for the vertical beam base 17 based on the connection of the pre-embedded part 18, the inner liner 12 and the vertical beam base 17 by the connector 191, the vertical beam base 17 is strengthened. This enhances the connection strength between the vertical beam base 17 and the refrigeration equipment 10. Furthermore, under conditions such as rapid door closure, the vertical beam base 17 may shift backward due to the impact force of the vertical beam. The rear support of the frame 13 can cooperate in bearing the force, reducing the risk of displacement of the vertical beam base 17 and maintaining the stability of the vertical beam base 17 in use.

[0353] In some embodiments, refer to Figure 31 and Figure 33 The front side of the frame 13 forms a first notch 132 that communicates with the second opening 133, and part of the vertical beam base 17 is embedded in the first notch 132.

[0354] In this embodiment, refer to Figure 31The first notch 132 can penetrate the frame 13 in the front-to-back direction, and the second opening 133 can penetrate the frame 13 in the vertical direction. The widths of the first notch 132 and the second opening 133 in the left-to-right direction are equal. In this way, the first notch 132 located on the front side of the frame 13 and the second opening 133 located on the inner side of the frame 13 can be directly connected. The first notch 132 and the second opening 133 directly form an L-shaped notch structure. During processing, the frame 13 can be cut once to simultaneously form the first notch 132 and the second opening 133, thereby simplifying the manufacturing process and accelerating production efficiency.

[0355] In other embodiments, the first notch 132 may only penetrate the frame 13 on the front side, while the rear side is still closed by a part of the frame 13. In other words, the first notch 132 may also be designed as a groove structure.

[0356] Reference Figure 33 The front portion of the base is embedded rearward into the first notch 132. The size of the first notch 132 can be designed to match the embedded portion. Specifically, the front portion of the base and the first notch 132 can form a transition fit or an interference fit. In this case, when the vertical beam base 17 is subjected to external forces such as vibration or impact, the first notch 132 can restrict the excessive movement of the vertical beam base 17, especially restricting the displacement of the vertical beam base 17 in the lateral direction.

[0357] The refrigeration device 10 provided in this application embodiment, through the structural design of the first notch 132 on the front side of the frame 13, partially embedding the vertical beam base 17, increases the contact area between the vertical beam base 17 and the frame 13, enhancing the connection strength and stability between the vertical beam base 17 and the frame 13. When the refrigeration device 10 is subjected to external force, the vertical beam base 17 can work better with the frame 13 to disperse stress, thereby reducing the probability of the vertical beam base 17 shaking or displacing, and thus maintaining the overall stability of the refrigeration device 10 structure. At the same time, the first notch 132 provides precise guidance and positioning for the installation of the vertical beam base 17, thereby reducing installation deviation and improving the installation accuracy of the vertical beam base 17. In addition, the first notch 132 and the second opening 133 can be formed simultaneously through a single cutting process, thereby simplifying the manufacturing process and accelerating production efficiency.

[0358] In some embodiments, refer to Figure 31 , Figure 33 and Figure 34The vertical beam base 17 includes a base body 171 and an extension section 172 that are bent and connected. The base body 171 has a first protrusion 1711. The base body 171 is connected to the inner liner 12 and the embedded part 18 through a connector 191. The base body 171 abuts against the inner top wall of the inner liner 12 and the mouth frame 13. The first protrusion 1711 is connected to the rear surface of the extension section 172. The extension section 172 is partially embedded in the first notch 132 and abuts against the outer periphery of the first notch 132.

[0359] In this embodiment, refer to Figure 31 , Figure 33 and Figure 34 The extended section 172 can be connected to the upper front side of the base body 171. The base body 171, as the core structure of the vertical beam base 17, serves to connect the inner liner 12 and the embedded part 18. The base body 171 can be tray-shaped. Specifically, the base body 171 can include a bottom plate and a flange connected to the bottom plate. The flange and the bottom plate can jointly define a recess, and a portion of the first protrusion 1711 is located in the recess. Since the base body 171 abuts against the inner top wall of the inner liner 12 and the opening frame 13, that is, the upper surface of the flange of the base body 171 is sealed with the inner top wall of the inner liner 12 and the inner top wall of the opening frame 13, the risk of foam material overflowing from the gap between the base body 171 and the inner liner 12 and the opening frame 13 during foaming is reduced. Based on the fact that the extension section 172 is partially embedded in the first notch 132 and abuts against the outer periphery of the first notch 132, specifically, a portion of the extension section 172 is located in front of the first notch 132, and the rear surface of the end of this portion forms a limiting fit with the outer periphery of the first notch 132 in the front-rear direction. When the vertical beam base 17 is subjected to external forces such as vibration and impact, if the vertical beam base 17 has a tendency to move backward, the frame 13 can abut against the extension section 172 of the vertical beam base 17 to limit its excessive backward movement. Combined with the limiting design of the first notch 132, the stability and reliability of the installation of the vertical beam base 17 are further increased.

[0360] In addition, refer to Figure 31 , Figure 33 and Figure 34 Based on the fact that the first protrusion 1711 is connected to the rear surface of the extension section 172, the extension section 172 is designed to avoid the front opening of the guide groove 17111 of the first protrusion 1711, so that the vertical beam can be smoothly inserted. The connection between the first protrusion 1711 and the extension section 172 further increases the structural strength of the first protrusion 1711.

[0361] In some embodiments, refer to Figure 34 The inner top wall of the mouth frame 13 protrudes from the inner top wall of the inner liner 12. The base body 171 is provided with a second notch 1712, which is used to accommodate the part of the mouth frame 13 that protrudes inward from the inner liner 12.

[0362] Understandably, referring to Figure 34 Due to manufacturing limitations, if the inner top wall of the mouth frame 13 were designed to be flush with the inner top wall of the inner liner 12, the connection would be difficult to achieve seamlessness, resulting in cleaning difficulties. Therefore, in the actual design, a portion of the mouth frame 13 protrudes inward from the inner top wall of the inner liner 12. In this case, the contact surface between the base body 171 and the mouth frame 13 must be lower than the contact surface between the base body 171 and the inner liner 12. If this height difference is not designed, the front part of the base body 171 will be flush with the mouth frame 13, while the rear part of the base body 171 will be suspended and separated from the inner top wall of the inner liner 12. Therefore, this application provides a second notch 1712 at the front part of the base body 171. The second notch 1712 is adapted to the shape of the part of the mouth frame 13 protruding inward from the inner liner 12. In this way, the rear part of the base body 171 can abut against the inner top wall of the inner liner 12, so that the base body 171 can simultaneously form a good sealing fit with the mouth frame 13 and the inner liner 12, reducing the phenomenon of dirt accumulation. At the same time, it prevents condensate from seeping in through the gap between the base body 171, the mouth frame 13, and the inner liner 12, thereby significantly reducing the corrosion rate of the inner liner 12 and effectively reducing the growth of mold.

[0363] In some embodiments, refer to Figure 32 In the case where the refrigeration device 10 includes a frame 13, the housing 11 clamps the top of the frame 13 and the top of the vertical beam base 17.

[0364] In this embodiment, refer to Figure 32 and Figure 33 The extension section 172 of the vertical beam base 17 extends upward to protrude beyond the first notch 132. The outer shell 11 can form a downward-open jaw. The upper part of the extension section 172 and the upper part of the jaw frame 13 both extend into the jaw. The jaw of the outer shell 11 can apply a stable clamping force to the upper part of the extension section 172 and the upper part of the jaw frame 13.

[0365] The refrigeration device 10 provided in this application embodiment, through the design of the outer shell 11 clamping the top of the frame 13 and the top of the vertical beam base 17, can assist the first notch 132 of the frame 13 in further fixing the extension section 172 of the vertical beam base 17, further increasing the bonding strength between the vertical beam base 17 and the frame 13, effectively reducing the loosening of the vertical beam base 17 caused by vibration or shaking, maximizing the stability and durability of the vertical beam base 17 assembly, and reducing the frequency of maintenance.

[0366] In some embodiments, refer to Figure 32 The top of the vertical beam base 17 is bent to form a receiving groove 1721, a portion of the front side of the housing 11 is located in the receiving groove 1721, and the housing 11 does not protrude forward from the vertical beam base 17.

[0367] In this embodiment, refer to Figure 32 The upper part of the extension section 172 of the vertical beam base 17 is bent backward and upward to form a receiving groove 1721. The outer shell 11 forms a jaw to clamp the upper part of the extension section 172 of the vertical beam base 17 and the upper part of the frame 13. A portion of the jaw of the outer shell 11 can be embedded in the receiving groove of the extension section 172, so that the front side of the outer shell 11 and the front side of the vertical beam base 17 will not form a step structure.

[0368] The refrigeration device 10 provided in this application embodiment, through the structural design that a portion of the front side of the outer shell 11 is located in the receiving groove 1721 of the vertical beam base 17, achieves that the front surface of the outer shell 11 does not protrude forward from the front surface of the vertical beam base 17, making the front surface of the refrigeration device 10 flatter, making the overall appearance of the refrigeration device 10 simpler and smoother, improving the overall aesthetics and texture of the refrigeration device 10, and better meeting consumers' requirements for product appearance.

[0369] In some embodiments, refer to Figure 30 , Figure 32 , Figure 34 and Figure 35 The connector 191 is vertically connected to the embedded part 18, the inner liner 12 and the vertical beam base 17 in sequence, and the connector 191 has an external thread. The embedded part 18 is provided with an upwardly protruding first mounting protrusion 183, and the first mounting protrusion 183 is provided with a first internal thread hole 1831 for engaging with the external thread. The vertical beam base 17 is provided with an upwardly protruding second mounting protrusion 1713, and the second mounting protrusion 1713 is provided with a second internal thread hole 17131 for engaging with the external thread.

[0370] In this embodiment, refer to Figure 30 , Figure 32 , Figure 34 and Figure 35The connector 191 is a screw. Both the first mounting protrusion 183 and the second mounting protrusion 1713 can be hollow columnar protrusions. The screw length can be determined based on the total thickness of the embedded part 18, the inner liner 12, and the second mounting protrusion 1713, as well as the installation allowance. The external thread of the connector 191 matches the first internal thread hole 1831 and the second internal thread hole 17131. During the installation of the connector 191, first align the first internal thread hole 1831, the corresponding connecting hole of the inner liner 12, and the second internal thread hole 17131. The operator passes the connector 191 from top to bottom through the first mounting protrusion 183, the main structure of the embedded part 18, the inner liner 12, and the second mounting protrusion 1713. Using a tool, rotate the connector 191 so that the external thread of the connector 191 engages with the first internal thread hole 1831 and the second internal thread hole 17131, and gradually tighten the connector 191. During the tightening process, care must be taken to control the tightening torque to avoid damaging the threads or components due to excessive tightening torque.

[0371] The refrigeration equipment 10 provided in this application embodiment, through the structural design of the above-mentioned connector 191 sequentially connecting the embedded part 18, the inner liner 12 and the vertical beam base 17 in the vertical direction, combined with the cooperation of the external thread with the first internal thread hole 1831 and the second internal thread hole 17131, can evenly distribute the vertical force (such as gravity and impact force) generated by the opening and closing of the door to the embedded part 18, the inner liner 12 and the vertical beam base 17. The first assembly protrusion 183 and the second assembly protrusion 1713 can significantly increase the threaded connection area, enhance the connection firmness between the embedded part 18, the inner liner 12 and the vertical beam base 17, effectively alleviate the stress concentration phenomenon caused by the force on the top wall of the inner liner 12, thereby significantly reducing the risk of cracking of the inner liner 12, and thus extending the service life of the refrigeration equipment 10.
