Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and mainly to a refrigeration device. Background Technology

[0002] A refrigeration device is a device that maintains a constant low temperature to store items, and it is widely used in modern life and industrial production. For example, a refrigerator has a refrigeration compartment inside, creating a refrigerated environment for the items to be refrigerated.

[0003] The refrigerator's casing includes a U-shaped shell and a lower front beam located at the bottom front of the U-shaped shell. The two sides of the lower front beam are connected to the bottom of the U-shaped shell with screws, thereby fixing it to the bottom of the U-shaped shell.

[0004] The lower front beam needs to be fixed to the U-shell with screws in both the horizontal and vertical directions. The fixing process increases the installation and production time, resulting in low production efficiency and the cost of installing multiple screws. Summary of the Invention

[0005] To address the issues of complex installation processes and low production efficiency in existing refrigerator casing technologies, a refrigeration device is provided to simplify the installation process and improve production efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: One aspect of this application provides a refrigeration device, including a cabinet liner with a refrigeration compartment having a front opening; a housing forming the outer shell of the refrigeration device; the housing being disposed outside the cabinet liner, the housing including a first sidewall disposed on the left side of the housing, the front side of the first sidewall having a first fixing portion extending and bending to the right, the bottom end of the first fixing portion having a first insertion groove; and a second sidewall disposed opposite to the first sidewall on the right side of the housing, the front side of the second sidewall having a second fixing portion extending and bending to the left. The second fixing part has a second insertion groove at its bottom end; the lower front beam is located at the front end of the bottom of the first side wall and the second side wall, and is located between the first side wall and the second side wall; wherein, one end of the lower front beam has a first insertion arm arranged opposite to the first insertion groove, and the other end of the lower front beam has a second insertion arm arranged opposite to the second insertion groove; one end of the lower front beam is inserted into the first insertion groove through the first insertion arm, and the other end of the lower front beam is inserted into the second insertion groove through the second insertion arm.

[0007] The above technical solution has the following advantages or beneficial effects: A first insertion slot is provided in the first fixing part, which is used to connect to one end of the lower front beam; a second insertion slot is provided in the second fixing part, which is used to connect to the other end of the lower front beam. One end of the lower front beam is provided with a first insertion arm corresponding to the first insertion slot, and the other end of the lower front beam is provided with a second insertion arm corresponding to the second insertion slot. This allows one end of the lower front beam to be directly inserted into the first insertion slot via the first insertion arm, thereby achieving the connection between one end of the lower front beam and the first side wall. The other end of the lower front beam is directly inserted into the second insertion slot via the second insertion arm, thereby achieving the connection between the other end of the lower front beam and the second side wall. Thus, the opposite ends of the lower front beam can be connected to both sides of the housing via insertion. Compared to the current structure that requires screws to fix it in all directions, the plug-in arms at both ends of the lower front beam form a connection structure with the opposite sides of the housing through plugging. This creates a lateral limit between the housing and the lower front beam, which not only better resists the left-right swaying and up-down displacement of the lower front beam, but also greatly simplifies the installation process, reduces installation steps and time, and thus effectively improves production efficiency.

[0008] In some embodiments of this application, a cooling device is provided, wherein one end of the lower front beam is provided with a first abutting arm, the first abutting arm being spaced apart on the back side of the first plug-in arm; the first abutting arm abuts against the back side of the bottom end of the first fixing part; the other end of the lower front beam is provided with a second abutting arm, the second abutting arm being spaced apart on the back side of the second plug-in arm; the second abutting arm abuts against the back side of the bottom end of the second fixing part.

[0009] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by providing a first abutting arm at intervals on the back side of the first plug-in arm, and the first abutting arm abutting against the bottom back side of the fixing part, the cooperation relationship between the lower front beam and the box body is further defined in the horizontal direction. By providing a second abutting arm at intervals on the back side of the second plug-in arm, and the second abutting arm abutting against the bottom back side of the fixing part, the cooperation relationship between the lower front beam and the box body is further defined in the horizontal direction. This can prevent the lower front beam from shaking or shifting in the horizontal direction, and increase the stability of the connection between the lower front beam and the box body.

[0010] In some embodiments of this application, a refrigeration device is provided, wherein the opening of the first insertion slot is arranged downwards, and the opening of the second insertion slot is arranged downwards; the lower front beam includes a base plate disposed at the bottom of the housing, the base plate being disposed between the bottom of the first side wall and the second side wall; a front side plate is bent upwards and extended from the front side of the base plate, the front side plate being disposed between the bottom of the first fixing part and the second fixing part; the first insertion arm is bent upwards and extended from one end of the base plate, and the first insertion arm is spaced apart on the side of the front side plate near the first side wall; the second insertion arm is bent upwards and extended from the other end of the base plate, and the second insertion arm is spaced apart on the side of the front side plate near the second side wall.

[0011] Another technical solution described above has the following advantages or beneficial effects: By arranging the first and second insertion slots with their openings facing downwards, when assembling the lower front beam, the operator only needs to align the first and second insertion arms of the lower front beam with the corresponding insertion slots and then place them from top to bottom to complete the insertion action. This also allows for height-direction limiting between the two ends of the lower front beam and the first and second side walls. Furthermore, this operation method is simple and intuitive, requiring no complex positioning and adjustment processes, thus greatly shortening the assembly time.

[0012] In some embodiments of this application, a cooling device is provided, wherein a first abutting arm extends from one end of the front side plate toward the first side wall; and a second abutting arm extends from the other end of the front side plate toward the second side wall.

[0013] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the first abutting arm abuts against the back of the first fixing part, that is, the interaction between the first abutting arm and the first side wall provides lateral support, thereby forming a front-rear limit between the lower front beam and the first fixing part. The first insertion arm extends upward and is arranged in the first insertion groove, thereby forming a vertical limit between the lower front beam and the first fixing part. Correspondingly, the second abutting arm abuts against the back of the second fixing part, that is, the interaction between the second abutting arm and the second side wall provides lateral support, thereby forming a front-rear limit between the lower front beam and the second fixing part. The second insertion arm extends upward and is arranged in the second insertion groove, thereby forming a vertical limit between the lower front beam and the second fixing part. In this way, a multi-directional force-bearing support structure is formed between the lower front beam and the first and second side walls, improving the strength and reliability of the assembly structure of the housing.

[0014] In some embodiments of this application, a cooling device is provided, wherein the lower front beam further includes a first connecting wall, the first connecting wall being connected between the front side plate and the first abutting arm, the first connecting wall extending rearward from one end of the front side plate, the rear end of the first connecting wall extending rearward to the back side of the first insert arm, and extending towards one side of the first side wall to form the first abutting arm; the lower front beam further includes a second connecting wall, the second connecting wall being connected between the front side plate and the second abutting arm, the second connecting wall extending rearward from one end of the front side plate, the rear end of the second connecting wall extending rearward to the back side of the second insert arm, and extending towards one side of the second side wall to form the second abutting arm.

[0015] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the rear end of the first connecting wall extends to the back side of the first insert arm, so that the first abutting arms can be spaced apart on the back side of the first insert arm. The rear end of the second connecting wall extends to the back side of the second insert arm, so that the second abutting arms can be spaced apart on the back side of the second insert arm. Moreover, the bent extension structures between the connecting wall and the front side plate and the first abutting arm, and the bent extension structures between the connecting wall and the front side plate and the second abutting arm, can provide guidance for the assembly process. When assembling the lower front beam, the operator can quickly and accurately determine the relative position of the first abutting arm and the front side plate, and the relative position of the second abutting arm and the front side plate, which is beneficial to improving the accuracy and efficiency of assembly.

[0016] In some embodiments of this application, a refrigeration device is provided, wherein the housing further includes a third sidewall, the third sidewall being disposed at the bottom of the housing, and the two sides of the third sidewall being connected between the bottoms of the first sidewall and the second sidewall; a first connecting hole is provided on the side of the third sidewall near the front end of the first sidewall, a second connecting hole is provided on the side of the third sidewall near the front end of the second sidewall, the bottom plate is located below the third sidewall, the bottom plate is provided with a third connecting hole corresponding to and communicating with the first connecting hole, and the bottom plate is provided with a fourth connecting hole corresponding to and communicating with the second connecting hole.

[0017] Another technical solution described above has the following advantages or beneficial effects: By providing the first and second connecting holes on the third sidewall, and the corresponding third and fourth connecting holes on the base plate, precise positioning is provided for the assembly of the base plate and the housing. During assembly, the operator inserts the first connecting arm into the first connecting slot and the second connecting arm into the second connecting slot, thus fixing both ends of the lower front beam to the first and second sidewalls. Then, the two ends of the base plate are aligned with the third and fourth connecting holes, and connectors such as bolts and screws are inserted into the corresponding connecting holes, quickly and conveniently completing the connection between the base plate and the housing. This significantly reduces positioning time and difficulty during assembly, improving assembly efficiency and accuracy.

[0018] In some embodiments of this application, a refrigeration device is provided, wherein the lower front beam further includes a first connecting portion, the first connecting portion is disposed on the back side of the front side plate, the first connecting portion is provided with a first snap-fit ​​groove, the opening of the first snap-fit ​​groove is arranged facing upward; the bottom of the box liner is provided with a first flange extending downward, the first flange is aligned and snapped into the first snap-fit ​​groove. Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the slot of the first snap-fit ​​groove is arranged with the groove facing upward, and the first flange at the bottom of the box can be easily aligned and snapped into the first snap-fit ​​groove from above. Through the alignment and snap-fit ​​of the first flange and the first snap-fit ​​groove, the operator can quickly and accurately connect the box to the lower front beam. In this process, the fixed connection between the lower front beam and the box does not require the use of additional assembly tools, which reduces assembly steps, reduces assembly complexity and labor intensity, and improves production efficiency.

[0019] In some embodiments of this application, a refrigeration device is provided. The first fixing part includes a first flange, which is bent and extended from the front side of the first sidewall toward the second sidewall; a first bent edge, which is bent and extended from the end of the first flange near the second sidewall toward the first sidewall; a first insertion groove is formed between the first bent edge and the first flange; a first insertion arm is disposed between the first flange and the first bent edge; and a first abutting arm abuts against the rear wall surface of the first bent edge.

[0020] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the first flange and the second flange bend and extend from the front side of the first sidewall and the second sidewall respectively. The first bent edge is bent in the opposite direction by the first flange, and the second bent edge is bent in the opposite direction by the second flange, thereby forming a compact first insertion groove and second insertion groove structure, so that the first fixing part and the second fixing part can achieve a reliable connection function in a limited space. Moreover, the first abutting arm abuts against the rear wall surface of the first bent edge, and the second abutting arm abuts against the rear wall surface of the second bent edge, so that when the lower front beam and the first sidewall and the second sidewall are subjected to force, the stress can be more evenly distributed, so that the stress will not be concentrated at a certain point or local area, but can be evenly transmitted and distributed through the structure of the first flange and the first bent edge, and the structure of the second flange and the second bent edge.

[0021] In some embodiments of this application, a cooling device is provided, wherein one end of the front side plate near the first fixing part is flush with the front wall of the first fixing part; and one end of the front side plate near the second fixing part is flush with the front wall of the second fixing part.

[0022] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by aligning the end of the front side plate near the first fixing part with the front wall of the first fixing part, the connection between the front side plate and the first fixing part is made neater and smoother; by aligning the end of the front side plate near the second fixing part with the front wall of the second fixing part, the connection between the front side plate and the second fixing part is made neater and smoother. This can reduce obvious protrusions or depressions at the front of the refrigeration device and improve the visual effect.

[0023] In some embodiments of this application, a cooling device is provided, wherein the upper end of the first plug-in arm is provided with a first gradient portion, the width of the first gradient portion gradually decreasing in the direction from bottom to top; the upper end of the second plug-in arm is provided with a second gradient portion, the width of the second gradient portion gradually decreasing in the direction from bottom to top.

[0024] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: When the operator installs the lower front beam on the front side of the box liner, the first plug-in arm is inserted into the corresponding first plug-in slot, and the second plug-in arm is inserted into the corresponding second plug-in slot. The tip of the first gradient part can first enter the entrance of the first plug-in slot, guiding the first plug-in arm to be inserted in the correct direction and position. The tip of the second gradient part can first enter the entrance of the second plug-in slot, guiding the second plug-in arm to be inserted in the correct direction and position. This greatly reduces the positioning difficulty and error in the assembly process and improves the accuracy and efficiency of assembly. Attached Figure Description

[0031] The refrigeration device in the embodiments of the present invention can be a freezer, refrigerator, or other refrigeration cabinet. The following uses a refrigerator as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0032] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0033] like Figure 1 As shown, the refrigeration device provided in this embodiment of the present invention includes a housing 1. The housing 1 can adopt a hollow structure such as a cuboid. The housing 1 forms the outer shell of the refrigeration device. It should be noted that the housing 1 can also adopt a hollow shell structure of other shapes.

[0034] In some embodiments, the housing 1 includes a refrigeration compartment 201, which can serve as an independent storage space. The refrigeration compartment 201 may have an opening, allowing users to store food within it. Multiple refrigeration compartments 201 may be provided.

[0035] In some embodiments, multiple refrigeration chambers 201 may be provided, which may be freezers, refrigerators, and variable temperature chambers, etc., to meet different refrigeration needs such as freezing, refrigeration, and variable temperature according to different types of food, and to store items that need to be refrigerated or frozen. The multiple refrigeration chambers 201 may be arranged vertically or horizontally.

[0036] In some embodiments, the refrigeration device may include a liner 2, with a housing 1 disposed outside the liner 2. A refrigeration chamber 201 may be formed inside the liner 2, and a foamed space may be formed between the liner 2 and the housing 1. By filling the space with foamed material, the refrigeration chamber 201 can achieve a good heat preservation effect. The refrigeration chamber 201 may have a front opening, allowing users to access and place items within it.

[0037] In some embodiments, the refrigeration unit may include a door (not shown). The door is movably mounted on the housing 1 and is used to open or close the refrigeration compartment 201.

[0038] Multiple doors can be installed, and multiple doors can be installed on multiple refrigeration compartments 201. The doors can be installed on the cabinet 1 by means of rotation or sliding.

[0039] In some embodiments, the refrigeration system includes a refrigeration system (not shown in the figure). The refrigeration system may be located inside the cabinet 1. The refrigeration system is used to provide cold air to the interior of the refrigerator to maintain a low-temperature environment in each refrigeration compartment 201.

[0040] In some embodiments, the refrigeration system includes a compressor (not shown). The compressor is the power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0041] In some embodiments, the refrigeration system includes a condenser (not shown). The condenser can be used to receive refrigerant flowing out of the compressor, cooling the high-temperature, high-pressure refrigerant gas from the compressor and converting it into a liquid state.

[0044] In some embodiments, the compressor, condenser, throttling device, and evaporator can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the interior of the housing 1.

[0045] Figure 2 for Figure 1 An exploded view; Figure 3 for Figure 1 A schematic diagram of the middle box.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 1 may include a first sidewall 11 and a second sidewall 12, which are arranged opposite to each other. The first sidewall 11 may be located on the left side of the housing 1 and may be fixed to the left side of the inner liner 2. The front side of the first sidewall 11 is provided with a first fixing part 111 that bends and extends to the right. The first fixing part 111 may be located at the left edge of the front opening of the inner liner 2. The bottom end of the first fixing part 111 is provided with a first insertion groove 101. The first fixing part 111 is formed by bending and extending to the right from the front side of the first sidewall 11. The first fixing part 111 and the first sidewall 11 are an integral structure and are not additional splicing parts. The first fixing part 111 has higher structural strength.

[0047] The second sidewall 12 can be located on the right side of the housing 1 and can be fixed to the right side of the inner liner 2. The front side of the second sidewall 12 is provided with a second fixing part 121 that bends and extends to the left. The second fixing part 121 can be located at the right edge of the front opening of the inner liner 2. The bottom end of the second fixing part 121 is provided with a second insertion groove 102. The second fixing part 121 is formed by bending and extending to the left from the front side of the second sidewall 12. The second fixing part 121 and the second sidewall 12 are an integral structure and are not additional splicing parts. The second fixing part 121 has higher structural strength.

[0048] The refrigeration device may include a lower front beam 13, which is located at the front end of the bottom of the first side wall 11 and the second side wall 12, and is located between the first side wall 11 and the second side wall 12. The two ends of the lower front beam 13 can be fixed to the bottom of the first side wall 11 and the second side wall 12 respectively. The first side wall 11, the second side wall 12 and the lower front beam 13 can be enclosed to form a shell structure covering the outside of the box liner 2, which protects the box liner 2.

[0049] Figure 4 for Figure 1 A cross-sectional view; Figure 5 for Figure 2 A magnified view of part A.

[0050] like Figure 4 and Figure 5 As shown, one end of the lower front beam 13 is provided with a first insertion arm 131 arranged opposite to the first insertion slot 101. One end of the lower front beam 13 is inserted into the first insertion slot 101 through the first insertion arm 131 so that one end of the lower front beam 13 can be connected to the box liner 2. The other end of the lower front beam 13 is provided with a second insertion arm 132 arranged opposite to the second insertion slot 102. The other end of the lower front beam 13 is inserted into the second insertion slot 102 through the second insertion arm 132 so that the other end of the lower front beam 13 can be connected to the box liner 2.

[0051] Specifically, the first fixing part 111 is provided with a first insertion slot 101, which is used to connect to one end of the lower front beam 13. The second fixing part 121 is provided with a second insertion slot 102, which is used to connect to the other end of the lower front beam 13. One end of the lower front beam 13 is provided with a first insertion arm 131 corresponding to the first insertion slot 101, and the other end of the lower front beam 13 is provided with a second insertion arm 132 corresponding to the second insertion slot 102. This allows one end of the lower front beam 13 to be directly inserted into the first insertion slot 101 through the first insertion arm 131, thereby connecting one end of the lower front beam 13 to the first side wall 11. The other end of the lower front beam 13 is directly inserted into the second insertion slot 102 through the second insertion arm 132, thereby connecting the other end of the lower front beam 13 to the second side wall 12. In this way, the two opposite ends of the lower front beam 13 can be connected to the two sides of the housing 1 by insertion. Compared to the current structure that requires screws to fix it in all directions, the plug arms at both ends of the lower front beam 13 form a connection structure with the opposite sides of the housing 1 by plugging them in. This forms a limit on both sides of the housing 1 and the lower front beam 13, which can not only better resist the left and right swaying and up and down displacement of the lower front beam 13, but also greatly simplify the installation process, reduce the installation steps and time, and thus effectively improve production efficiency.

[0052] Currently, the opposite sides of the U-shaped shell in the refrigerator, namely the first sidewall 11 and the second sidewall 12, need to be screwed to both ends of the lower front beam 13 in the horizontal and vertical directions, respectively. Operators need to set the connection holes on the first sidewall 11 and the second sidewall 12 one by one at both ends of the lower front beam 13, and drill additional holes in the horizontal and vertical directions to tighten screws. The screw positioning and reinforcement process is cumbersome, and the fixed connection process increases the installation and production time. The production efficiency is low, and it also includes the cost of installing multiple screws.

[0053] In the technical solution of this application, a first fixing part 111 with a first insertion groove 101 is provided on the front side of the first side wall 11 of the housing 1, which bends and extends to the right. A second fixing part 121 with a second insertion groove 102 is provided on the front side of the second side wall 12, which bends and extends to the left. The lower front beam 13 has a first insertion arm 131 opposite to the first insertion groove 101 and a second insertion arm 132 opposite to the second insertion groove 102 at both ends. The lower front beam 13 is fixed by directly inserting the insertion arms into the first insertion groove 101 and the second insertion groove 102. Compared with traditional screw fixing, the insertion fixing method of the lower front beam 13 to the housing 1 greatly simplifies the installation process, reduces installation steps and time, and thus effectively improves production efficiency. Furthermore, it reduces the use of a large number of screws and the number of parts used, thereby reducing production costs.

[0054] In some embodiments, the first insertion arm 131 of the lower front beam 13 is inserted into the first insertion slot 101, and the second insertion arm 132 of the lower front beam 13 is inserted into the second insertion slot 102, which can limit the lower front beam 13 and the housing 1 in the height direction. In other embodiments, the second insertion arm 132 of the lower front beam 13 is inserted into the second insertion slot 102, and the second insertion arm 132 of the lower front beam 13 is inserted into the second insertion slot 102, which can limit the lower front beam 13 and the housing 1 in the height direction.

[0055] like Figure 1 As shown, in some embodiments, the end of the front side plate 136 near the first fixing part 111 may be flush with the front wall of the first fixing part 111.

[0056] By aligning one end of the front side panel 136 near the first fixing part 111 with the front wall of the first fixing part 111, the connection between the front side panel 136 and the first fixing part 111 becomes neater and smoother, reducing obvious protrusions or depressions at the front of the refrigeration device and improving the visual effect.

[0057] In some embodiments, the end of the front side plate 136 near the second fixing part 121 may be flush with the front wall of the second fixing part 121.

[0058] By aligning one end of the front side panel 136 near the second fixing part 121 with the front wall of the second fixing part 121, the connection between the front side panel 136 and the second fixing part 121 becomes neater and smoother, reducing obvious protrusions or depressions at the front of the refrigeration device and improving the visual effect.

[0059] Figure 6 for Figure 1 A schematic diagram of the lower front beam.

[0060] like Figure 6 As shown, in some embodiments, the upper end of the first connector arm 131 is provided with a first gradient portion 1311, the width of which gradually decreases from bottom to top. The upper end of the second connector arm 132 is provided with a second gradient portion 1321, the width of which gradually decreases from bottom to top.

[0061] Specifically, by providing a first gradient portion 1311 at the upper end of the first plug-in arm 131 and a second gradient portion 1321 at the upper end of the second plug-in arm 132, the gradient structure of the first gradient portion 1311 and the second gradient portion 1321 is beneficial to providing a good guiding effect for the plug-in structure of the lower front beam 13 with the first fixing portion 111 and the second fixing portion 121.

[0062] During the installation of the lower front beam 13 on the front side of the housing liner 2, the operator inserts the first connector arm 131 into the corresponding first connector slot 101, and the second connector arm 132 into the corresponding second connector slot 102. The tip of the first tapered section 1311 can first enter the entrance of the first connector slot 101, guiding the first connector arm 131 to be inserted in the correct direction and position. Similarly, the tip of the second tapered section 1321 can first enter the entrance of the second connector slot 102, guiding the second connector arm 132 to be inserted in the correct direction and position. This significantly reduces the positioning difficulty and errors during assembly, improving assembly accuracy and efficiency. Moreover, even with some deviation during the insertion process, the inclined surface of the tapered section can interact with the edge of the connector slot, facilitating automatic adjustment of the connector arm's position during installation, gradually aligning it with the connector slot. This not only reduces assembly errors but also simplifies installation, further improving production efficiency.

[0063] Figure 7 for Figure 1 Another three-dimensional schematic diagram of the lower front beam; Figure 8 for Figure 1 Another three-dimensional schematic diagram of the lower front beam.

[0064] like Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, one end of the lower front beam 13 is provided with a first abutment arm 133, which may be provided at intervals on the back side of the first insertion arm 131. The first abutment arm 133 may abut against the back side of the bottom end of the first fixing part 111.

[0065] Specifically, the first insertion arm 131 of the lower front beam 13 is inserted into the first insertion slot 101 to limit the lower front beam 13 in a specific direction. A first abutment arm 133 is provided at intervals on the back side of the first insertion arm 131, and the abutment arm 133 abuts against the bottom back side of the fixing part, further limiting the horizontal fit between the lower front beam 13 and the housing 1. This prevents the lower front beam 13 from swaying or shifting horizontally, increasing the stability of the connection between the lower front beam 13 and the housing 1, and making the entire refrigeration device structure more reliable. Furthermore, the first abutment arm 133 abuts against the back side of the first fixing part 111, providing support for the first fixing part 111. When the first fixing part 111 or the lower front beam 13 is subjected to external force, the force can be distributed to the first abutment arm 133 and the first fixing part 111, avoiding the problem of poor structural strength due to only an insertion structure and the easy deformation of the first fixing part 111.

[0066] In some embodiments, the other end of the lower front beam 13 is provided with a second abutment arm 134, which may be provided at intervals on the back side of the second insertion arm 132. The second abutment arm 134 may abut against the back side of the bottom end of the second fixing part 121.

[0067] Specifically, the second insertion arm 132 of the lower front beam 13 is inserted into the second insertion slot 102 to limit the lower front beam 13 in a specific direction. Second abutment arms 134 are provided at intervals on the back side of the second insertion arm 132. The abutment arms 134 abut against the bottom back side of the fixing part, further limiting the horizontal fit between the lower front beam 13 and the housing 1. This prevents the lower front beam 13 from swaying or shifting horizontally, increasing the stability of the connection between the lower front beam 13 and the housing 1. Furthermore, the second abutment arms 134 abut against the back side of the second fixing part 121, providing support for the second fixing part 121. When the second fixing part 121 or the lower front beam 13 is subjected to external force, the force is distributed to the second abutment arms 134 and the second fixing part 121, avoiding the problem of poor structural strength due to only an insertion structure and the easy deformation of the second fixing part 121.

[0068] Furthermore, by having the first abutting arm 133 spaced apart on the back side of the first plug-in arm 131 and the second abutting arm 134 spaced apart on the back side of the second plug-in arm 132, the first abutting arm 133 can make full use of the space between the lower front beam 13 and the first fixing part 111, and the second abutting arm 134 can make full use of the space between the lower front beam 13 and the second fixing part 121. While maintaining the connection stability and structural strength between the housings 1, the assembly structure of the housing 1 of the refrigeration device is made more compact.

[0069] like Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, the opening of the first insertion slot 101 is arranged downwards, and the first insertion arm 131 can be inserted upwards into the first insertion slot 101 through its opening. The opening of the second insertion slot 102 is also arranged downwards, and the second insertion arm 132 can be inserted upwards into the second insertion slot 102 through its opening.

[0070] The lower front beam 13 may include a bottom plate 135 and a front side plate 136. The bottom plate 135 is located at the bottom of the housing 1 and below the front end of the bottom wall of the housing liner 2. The bottom plate 135 is located between the bottom of the first side wall 11 and the second side wall 12, and the length of the bottom plate 135 may extend along the interval between the first side wall 11 and the second side wall 12.

[0071] The front side plate 136 can be bent upward from the front side of the base plate 135 and extended upward. The front side plate 136 can be disposed between the bottom of the first fixing part 111 and the second fixing part 121, and the length direction of the front side plate 136 can extend along the interval between the first fixing part 111 and the second fixing part 121. The left and right ends of the base plate 135 are respectively set beyond the left and right ends of the front side plate 136, that is, the length of the base plate 135 is greater than that of the front side plate 136.

[0072] The first plug-in arm 131 extends upward from one end of the base plate 135 and is spaced apart on the side of the front side plate 136 near the first side wall 11. The second plug-in arm 132 extends upward from the other end of the base plate 135 and is spaced apart on the side of the front side plate 136 near the second side wall 12.

[0073] Specifically, by arranging the first insertion slot 101 and the second insertion slot 102 downwards, when assembling the lower front beam 13, the operator only needs to align the first insertion arm 131 and the second insertion arm 132 of the lower front beam 13 with the corresponding insertion slots, and then place it from top to bottom to complete the insertion action. This also allows for height-directed positioning between the two ends of the lower front beam 13 and the first side wall 11 and the second side wall 12. Furthermore, this operation method is simple and intuitive, eliminating the need for complex positioning and adjustment processes, thus significantly shortening assembly time. Compared to some structures that require insertion from the side or a specific angle, the downward-facing slot design reduces assembly difficulty and error rate, improving assembly efficiency.

[0074] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the first abutment arm 133 may extend from one end of the front side plate 136 toward the first sidewall 11. The second abutment arm 134 may extend from the other end of the front side plate 136 toward the second sidewall 12.

[0075] Specifically, the first abutting arm 133 extends from one end of the front side plate 136 toward the first side wall 11, so that the first abutting arm 133 can extend to the back side of the first fixing part 111, and the second abutting arm 134 extends from the other end of the front side plate 136 toward the second side wall 12, so that the first abutting arm 133 can extend to the back side of the second fixing part 121.

[0076] The first abutting arm 133 abuts against the back of the first fixing part 111, that is, the interaction between the first abutting arm 133 and the first side wall 11 provides lateral support, thereby limiting the lower front beam 13 and the first fixing part 111 in the front-rear direction. The first insertion arm 131 extends upward into the first insertion groove 101, thereby limiting the lower front beam 13 and the first fixing part 111 in the vertical direction. Correspondingly, the second abutting arm 134 abuts against the back of the second fixing part 121, that is, the interaction between the second abutting arm 134 and the second side wall 12 provides lateral support, thereby limiting the lower front beam 13 and the second fixing part 121 in the front-rear direction. The second insertion arm 132 extends upward into the second insertion groove 102, thereby limiting the lower front beam 13 and the second fixing part 121 in the vertical direction. In this way, the lower front beam 13 forms a multi-directional force-supporting structure with the first side wall 11 and the second side wall 12, which improves the strength and reliability of the assembly structure of the box body 1.

[0077] In some other embodiments, the opening of the first insertion slot 101 can face the second sidewall 12, the opening of the second insertion slot 102 can face the first sidewall 11, the first insertion arm 131 can extend from one end of the front sideplate 136 toward the first sidewall 11, and the first insertion arm 131 is correspondingly inserted into the first insertion slot 101. The second insertion arm 132 can extend from the other end of the front sideplate 136 toward the second sidewall 12, and the second insertion arm 132 can correspondingly be inserted into the second insertion slot 102. The first abutting arm 133 can extend upward from one end of the base plate 135, and the second abutting arm 134 can extend upward from the other end of the base plate 135.

[0078] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the lower front beam 13 may include a first connecting wall 137, which may extend in a front-rear direction and connect the front side plate 136 and the first abutment arm 133. The first connecting wall 137 may be bent and extended rearward from one end of the front side plate 136, and the rear end of the first connecting wall 137 may extend rearward to the back side of the first insertion arm 131 and bend and extend towards one side of the first side wall 11 to form the first abutment arm 133.

[0079] The rear end of the first connecting wall 137 extends to the back side of the first insert arm 131, allowing the first abutting arm 133 to be spaced apart on the back side of the first insert arm 131. The integral molding of the connecting wall with the front side plate 136 and the first abutting arm 133, along with the bending extension structure between the connecting wall and the front side plate 136 and the first abutting arm 133, provides guidance for the assembly process. When assembling the lower front beam 13, the operator can quickly and accurately determine the relative position of the first abutting arm 133 and the front side plate 136, improving assembly accuracy and efficiency. Furthermore, when the lower front beam 13 is inserted downwards into the first insert groove 101, the first insert arm 131 can extend through the back of the first fixing part 111 and abut against it, thereby abutting against the first fixing part 111 and the first insert arm 131 inserted into the first insert groove 101 and providing forward support.

[0080] The first connecting wall 137 is integrally formed with the front side plate 136 and the first abutting arm 133, eliminating the need for additional connections or splicing, thus simplifying the structure of the lower front beam 13 and reducing production costs.

[0081] The lower front beam 13 may include a second connecting wall 138, which may extend in a front-rear direction and may connect the front side plate 136 and the second abutment arm 134. The second connecting wall 138 extends rearward from one end of the front side plate 136, and its rear end extends rearward to the back side of the second insertion arm 132, and then extends towards one side of the second side wall 12 to form the second abutment arm 134.

[0082] The rear end of the second connecting wall 138 extends to the back side of the second insert arm 132, allowing the second abutting arms 134 to be spaced apart on the back side of the second insert arm 132. The integral molding of the connecting wall with the front side plate 136 and the second abutting arms 134, along with the bent extension structures between the connecting wall and the front side plate 136 and the second abutting arms 134, provides guidance during assembly. When assembling the lower front beam 13, the operator can quickly and accurately determine the relative position of the second abutting arms 134 and the front side plate 136, improving assembly accuracy and efficiency. Furthermore, when the lower front beam 13 is inserted downwards into the second insert groove 102, the second insert arm 132 can extend through the back of the second fixing part 121 and abut against it, thereby abutting against the second fixing part 121 and the second insert arm 132 inserted into the second insert groove 102 and providing forward support.

[0083] Figure 9 for Figure 1 Bottom diagram; Figure 10 for Figure 1 Another exploded view.

[0084] like Figure 9 and Figure 10 As shown, the second connecting wall 138 is integrally formed with the front side plate 136 and the second abutment arm 134, eliminating the need for additional connections or splicing, thus simplifying the structure of the lower front beam 13 and reducing production costs.

[0085] In some embodiments, the housing 1 includes a third sidewall 14, which may be disposed at the bottom of the housing 1 and serve as the bottom wall of the housing 1. The two sides of the third sidewall 14 are connected between the bottoms of the first sidewall 11 and the second sidewall 12.

[0086] The third sidewall 14 has a first connecting hole 103 on the side near the front end of the first sidewall 11, and a second connecting hole 104 on the side near the front end of the second sidewall 12.

[0087] The base plate 135 is located below the third side wall 14. The base plate 135 is provided with a third connecting hole 105 that corresponds to and communicates with the first connecting hole 103. The base plate 135 is also provided with a fourth connecting hole 106 that corresponds to and communicates with the second connecting hole 104.

[0088] Specifically, the third sidewall 14 connects between the bottoms of the first sidewall 11 and the second sidewall 12, thus forming a more complete and stable frame structure for the housing 1. The bottom plate 135 is located at the bottom of the third sidewall 14, with both ends extending to opposite sides of the third sidewall 14. The first connecting hole 103 and the second connecting hole 104 on the third sidewall 14, and the corresponding third connecting hole 105 and fourth connecting hole 106 on the bottom plate 135, provide precise positioning for the assembly of the bottom plate 135 with the housing 1. During assembly, the operator inserts the first insertion arm 131 into the first insertion slot 101 and the second insertion arm 132 into the second insertion slot 102, so that the two ends of the lower front beam 13 are fixed on the first side wall 11 and the second side wall 12. Then, the two ends of the base plate 135 are aligned with the third connection hole 105 and the fourth connection hole 106 respectively. By inserting connectors such as bolts and screws into the corresponding connection holes, the connection between the base plate 135 and the housing 1 is completed quickly and conveniently, which greatly reduces the positioning time and difficulty in the assembly process and improves the assembly efficiency and accuracy.

[0089] In this way, the lower front beam 13 can be connected to the first side wall 11, the second side wall 12 and the third side wall 14 respectively, so that the lower front beam 13 can be firmly fixed to the bottom front side of the box body 1, and the connection tightness between the lower front beam 13 and the first side wall 11 and the second side wall 12 can be further improved.

[0090] On the other hand, the two ends of the lower front beam 13 are respectively inserted into the first side wall 11 and the second side wall 12 to form a limit in the height direction, that is, the vertical direction. The two ends of the lower front beam 13 abut against the first fixing part 111 through the first abutting arm 133 and the second fixing part 121 through the second abutting arm 134, thereby forming a limit in the horizontal direction, that is, the front-back direction. In addition, the two ends of the bottom plate 135 of the lower front beam 13 are fixedly connected to the third side wall 14 through the connectors, forming a reliable connection between the lower front beam 13 and the first side wall 11, the second side wall 12, and the third side wall 14. In this way, the lower front beam 13 only needs to be fixedly connected to the third side wall 14 by a connector at the bottom. Compared with the existing technology, which requires screws, bolts and other connectors to be set in each direction for fastening, fewer parts can be used, and the assembly efficiency can be effectively improved.

[0091] like Figure 7 and Figure 10 As shown, in some embodiments, the lower front beam 13 may include a first connecting portion 139 for connecting to the bottom of the inner box 2.

[0092] The first connecting part 139 is located on the back side of the front side plate 136. The first connecting part 139 is provided with a first snap-fit ​​groove 107, which can extend along the length direction of the lower front beam 13, and the groove opening of the first snap-fit ​​groove 107 is arranged facing upward. The bottom of the cabinet liner 2 is provided with a first flange 21 extending downward. The first flange 21 is located at the bottom edge of the front opening of the refrigeration compartment 201, and the first flange 21 is aligned and snapped into the first snap-fit ​​groove 107. In this configuration, the opening of the first snap-fit ​​groove 107 faces upward, and the first flange 21 at the bottom of the box liner 2 can be easily aligned and snapped into the first snap-fit ​​groove 107 from above. Through the alignment and snap-fit ​​between the first flange 21 and the first snap-fit ​​groove 107, the operator can quickly and accurately connect the box liner 2 and the lower front beam 13. In this process, the fixed connection between the lower front beam 13 and the box liner 2 does not require the use of additional assembly tools, which reduces assembly steps, reduces assembly complexity and labor intensity, and improves production efficiency.

[0093] In some embodiments, the first connecting portion 139 can be bent from the top of the front side plate 136 toward the inner box 2, forming a first snap-fit ​​groove 107 with the slot facing upward. When the lower front beam 13 is inserted from bottom to top into the first snap-fit ​​groove 101 and the second snap-fit ​​groove 102, the opening of the first snap-fit ​​groove 107 can be provided corresponding to the first flange 21, so that a tight fit structure can be formed with the inner box 2 during the installation of the lower front beam 13, improving the assembly reliability between the box body 1 and the inner box 2.

[0094] like Figure 10As shown, in some embodiments, the first sidewall 11 may be provided with a second connecting portion 112, which is used to connect with the left side of the box liner 2. The second connecting portion 112 may be provided on the back of the first fixing portion 111, and the second connecting portion 112 may be provided with a second snap-fit ​​groove 108. The second snap-fit ​​groove 108 may extend along the height direction of the box liner 2, and the groove opening of the second snap-fit ​​groove 108 is arranged facing the right. The left side of the box liner 2 is provided with a second flange 22 that bends and extends toward the first sidewall 11, and the second flange 22 can be aligned and snapped into the second snap-fit ​​groove 108. like Figure 10 As shown, in some embodiments, the second sidewall 12 may be provided with a third connecting portion 122, which is used to connect with the right side of the box liner 2. The third connecting portion 122 may be provided on the back of the second fixing portion 121, and the third connecting portion 122 may be provided with a third snap-fit ​​groove 109. The third snap-fit ​​groove 109 may extend along the height direction of the box liner 2, and the groove opening of the third snap-fit ​​groove 109 is arranged facing the left. The right side of the box liner 2 is provided with a third flange 23 that bends and extends toward the second sidewall 12, and the third flange 23 can be aligned and snapped into the third snap-fit ​​groove 109.

[0095] like Figure 3 and Figure 4 As shown, in some embodiments, the first fixing part 111 may include a first flange 1111 and a first bent edge 1112. The first flange 1111 may be bent and extended from the front side of the first sidewall 11 toward the second sidewall 12. The first flange 1111 may be located on the front side of the second flange 22. The first bent edge 1112 may be bent and extended from the end of the first flange 1111 near the second sidewall 12 toward the first sidewall 11. The first flange 1111 and the first bent edge 1112 may have a U-shaped structure. A first insertion groove 101 is formed between the first bent edge 1112 and the first flange 1111. A first insertion arm 131 is located between the first flange 1111 and the first bent edge 1112. A first abutting arm 133 abuts against the rear wall surface of the first bent edge 1112.

[0096] The second fixing part 121 may include a second flange 1211 and a second bent edge 1212. The second flange 1211 extends from the front side of the second sidewall 12 toward the first sidewall 11. The second bent edge 1212 extends from the end of the second flange 1211 near the first sidewall 11 toward the second sidewall 12. The second flange 1211 and the second bent edge 1212 may have a U-shaped structure, and a second insertion groove 102 is formed between the second bent edge 1212 and the second flange 1211. A second insertion arm 132 is disposed between the second flange 1211 and the second bent edge 1212; a second abutting arm 134 abuts against the rear wall surface of the second bent edge 1212.

[0097] The first flange 1111 and the second flange 1211 extend from the front of the first sidewall 11 and the second sidewall 12 respectively. The first bent edge 1112 is bent in the opposite direction by the first flange 1111, and the second bent edge 1212 is bent in the opposite direction by the second flange 1211, thereby forming a compact first insertion groove 101 and second insertion groove 102 structure, so that the first fixing part 111 and the second fixing part 121 can achieve a reliable connection function in a limited space. Furthermore, the first abutting arm 133 abuts against the rear wall surface of the first bent edge 1112, and the second abutting arm 134 abuts against the rear wall surface of the second bent edge 1212, so that when the lower front beam 13 and the first side wall 11 and the second side wall 12 are subjected to force, the stress can be more evenly distributed, so that the stress will not be concentrated at a certain point or local area, but can be evenly transmitted and distributed through the structure of the first flange 1111 and the first bent edge 1112, and the structure of the second flange 1211 and the second bent edge 1212.

[0098] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
