[0027] The embodiments of this application are described in detail below. Examples of the 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.

[0028] The following is for reference. Figures 1-10 This application describes a refrigeration device according to an embodiment of the present application.

[0029] It should be noted that the storage device in this embodiment can be understood as a refrigeration storage device in a broad sense, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. The storage devices have diverse structural forms and a wide range of applications.

[0030] The storage equipment includes a box and a door. The box includes an outer shell, an inner liner, and an insulation layer between the outer shell and the inner liner. The outer shell covers the inner liner and provides protection. The insulation layer can be a foam layer, which provides insulation and cushioning. A compressor compartment is formed between the outer shell and the inner liner. The compressor compartment is used to house machines such as compressors and heat dissipation components.

[0031] like Figure 1 and Figure 2 As shown, the refrigeration equipment provided according to the embodiments of this application includes a housing, a compressor support plate 3, and an integrated component 2.

[0032] The cabinet includes an inner liner 12, an outer shell 11, and an insulation layer disposed between the inner liner 12 and the outer shell 11. The inner liner 12 forms a storage compartment 121.

[0033] The integrated component 2 is located on one side of the enclosure. The integrated component 2 includes a main shell 21, a cabin cover 22, a bottom insulation layer 23, and an evaporator 24. The main shell 21 forms a refrigeration chamber 211, the evaporator 24 is located in the refrigeration chamber 211, and the bottom insulation layer 23 is located between the main shell 21 and the cabin cover 22. The compressor support plate 3 and the nacelle cover plate 22 form a compressor compartment 6, which is used to house the compressor 4 and the heat dissipation components. At least a portion of the compressor compartment 6 is located on the front side of the refrigeration compartment 211.

[0034] The integrated component 2 is disposed on one side of the housing. For example, the integrated component 2 can be disposed at the end of the housing along the height direction, such as below the bottom end or above the top end of the housing; or, the integrated component 2 can be disposed at the end of the housing along the left and right direction, such as the left side of the left end or the right side of the right end of the housing; or, the integrated component 2 can be disposed on the rear side of the back of the housing.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, the integrated component 2 is located below the end of the housing along the height direction.

[0036] In other words, the integrated component 2 constitutes a "base" or "base" part of the refrigeration equipment, while the cabinet sits on the base as a pure "storage compartment".

[0037] In this embodiment, there are no refrigeration compartments 211 or equipment encroaching on the interior of the enclosure, which can achieve the theoretical maximum volume ratio and the most flexible internal shelving layout.

[0038] Meanwhile, any malfunctions or maintenance of the refrigeration system can be performed entirely within the base. Maintenance will not affect the items in storage compartment 121, and users do not need to empty the cabinet. The base can even be designed to be pulled out as a whole or disassembled independently, achieving "maintenance without emptying" and improving the user experience.

[0039] Meanwhile, the heat is completely isolated at the bottom of the refrigeration equipment and dissipates directly to the surrounding environment through the outer shell 11 of the integrated component 2, minimizing the temperature interference of the storage room 121, which is conducive to precise temperature control and energy saving.

[0040] The entire refrigeration compartment 211 and its internal evaporator 24 are housed as a separate integrated component 2 on the outside of the outer shell 11. Since the refrigeration compartment 211 and evaporator 24 no longer need to be integrated inside the inner liner 12, the bottom of the inner liner 12 can be designed as a completely flat surface, eliminating the need for any recesses or protrusions to accommodate the evaporator 24, air ducts, or drainage, thus simplifying the structure of the inner liner 12. The inner liner 12 is a complete cube, reducing protrusions or recesses, resulting in a more regular space, maximizing storage space utilization, and making internal cleaning easier.

[0041] Furthermore, the inner liner module 12 and the refrigeration system module can be produced and tested for performance (such as airtightness and cooling capacity) completely independently and in parallel, greatly improving the flexibility and efficiency of the production line. During final assembly, only the pre-installed refrigeration module needs to be piped to the inner liner module 12. In case of failure, the entire refrigeration module can be quickly disassembled and replaced, making maintenance convenient and reducing after-sales costs.

[0042] Meanwhile, the heat generated by the refrigeration system is completely isolated from the outside of the inner liner 12, which helps to maintain a more stable low-temperature environment inside the storage compartment 121 and improve energy efficiency.

[0043] In this embodiment, the integrated component 2 integrates the evaporator 24 and the refrigeration chamber 211. With the compressor support plate 3 pre-installed on the integrated component 2, it can also integrate the compressor chamber 6, compressor 4, and heat dissipation components. It can function as an independent pre-installed module, enabling a highly modular design and significantly simplifying the final assembly process. During the overall assembly, only the integrated component 2 needs to be assembled and connected to the inner liner 12, significantly improving production efficiency. Simultaneously, the integrated component 2 can be pre-tested and verified as an independent functional module, improving the compatibility and reliability of each component, thereby enhancing the overall quality of the machine.

[0044] The main shell 21 can form an independent cooling chamber 211, or it can form a cooling chamber 211 together with the outer shell 11.

[0045] For example, the assembly between the inner liner 12 and the integrated component 2 includes at least the following two methods.

[0046] Firstly, such as Figure 2 As shown, the bottom of the main housing 21 has an opening, and the outer shell 11 and the opening are sealed together to form a refrigeration chamber 211.

[0047] The integrated component 2 also includes a cooling chamber 27, which together with the main shell 21 forms a cooling compartment 211.

[0048] The main shell 21 has an opening, and the cooling liner 27 closes the opening to form an insulated space with a bottom foam layer. The cooling liner 27 forms a cooling chamber 211 with an opening. The bottom of the outer shell 11 seals the opening of the main shell 21, thereby sealing the cooling liner 27 to form the cooling chamber 211. The bottom of the outer shell 11, the main shell 21, and the cooling liner 27 enclose the cooling chamber 211.

[0049] The bottom of the outer casing 11 is sealed to the open portion of the main casing 21, which can reduce cold leakage.

[0050] For example, the bottom of the outer casing 11 and the opening of the main casing 21 can be sealed by a sealing ring press-fit: a sealing ring mounting groove is provided around the opening, and an annular sealing ring is placed in the groove. When the bottom of the outer casing 11 is assembled with the main casing 21, the two are pressed together by fasteners, causing the sealing ring to elastically deform and fill the gap between the bottom of the outer casing 11 and the main casing 21, forming a reliable seal.

[0051] For example, the bottom of the outer shell 11 and the main shell 21 can be sealed by adhesive: sealant is applied to the bottom of the outer shell 11 and the edge of the main shell 21, the bottom of the outer shell 11 and the main shell 21 are pressed together, and a permanent sealed connection is achieved after the sealant cures.

[0052] For example, the bottom of the outer shell 11 and the main shell 21 can be sealed by welding: when the bottom of the outer shell 11 and the main shell 21 are made of compatible plastic materials, the periphery of the integrated component 2 can be fused together with the bottom of the outer shell 11 by processes such as hot plate welding and ultrasonic welding to form an integrated sealed structure.

[0053] For example, the bottom of the outer casing 11 and the main casing 21 can be sealed by a snap-fit ​​seal: a snap-fit ​​structure with a sealing strip is provided around the opening, and a corresponding slot is provided at the bottom of the outer casing 11. During assembly, quick connection is achieved through the cooperation of the snap-fit ​​and the slot, while sealing is achieved through the sealing strip.

[0054] Secondly, the main shell 21 is a complete structure, and the cooling chamber 27 and the main shell 21 form a cooling compartment 211.

[0055] The integrated component 2 also includes a cooling tank 27, which together with the main housing 21 forms a cooling chamber 211. The cooling tank 27 has a downwardly recessed mounting groove, and the top cover of the main housing 21 is complete without any openings. The main housing 21 closes the opening of the mounting groove to form the cooling chamber 211.

[0056] Thirdly, such as Figure 5 As shown, the integrated component 2 also includes a cooling top cover 28, a cooling tank 27, and the cooling top cover 28 together form a cooling chamber 211.

[0057] The cooling chamber 27 has a downwardly recessed mounting groove, and the top cover of the main housing 21 has an opening aligned with the mounting groove. The cooling top cover 28 closes the mounting groove and the opening of the main housing 21 to form a cooling chamber 211. The cooling components inside the cooling chamber 211 can be installed and maintained by opening the cooling top cover 28, thereby reducing maintenance costs.

[0058] The cooling tank 27 and the cooling top cover 28 are detachably connected. For example, the cooling tank 27 and the cooling top cover 28 can be connected by screws, bolts and clips, or quick-release clamps.

[0059] The design of the detachable connection between the cooling chamber 27 and the cooling top cover 28 allows the interior of the cooling chamber 211 to be directly exposed by simply removing the cooling top cover 28 when it is necessary to clean the interior of the cooling chamber 211, inspect or replace the evaporator 24, without disassembling the entire integrated assembly 2, which greatly simplifies the maintenance operation.

[0060] In some embodiments, such as Figure 8 As shown, the cooling top cover 28 has a first snap-fit ​​structure 281, and the cooling liner 27 has a second snap-fit ​​structure 272 that snaps into the first snap-fit ​​structure 281.

[0061] During assembly, align the cooling top cover 28 with the cooling body 27, apply pressure or push it in a specific direction to make the first snap-fit ​​structure 281 and the second snap-fit ​​structure 272 engage with each other, thus achieving a quick and reliable connection between the two without any tools.

[0062] In the above three ways of forming a cooling chamber 211 from the main shell 21, the bottom of the outer shell 11 can be flat, the outer shell 11 has a simple and complete structure, and reduces the manufacturing difficulty.

[0063] At least a portion of the compressor compartment 6 is located in front of the refrigeration compartment 211 in the front-rear direction. In other words, at least a portion of the vertical orthographic projection of the compressor compartment 6 is located in front of the vertical orthographic projection of the refrigeration compartment 211 in the front-rear direction.

[0064] For example, the vertical orthographic projection of the compressor compartment 6 is located in front of the vertical orthographic projection of the refrigeration compartment 211 in the front direction; or, a portion of the vertical orthographic projection of the compressor compartment 6 is located in front of the vertical orthographic projection of the refrigeration compartment 211 in the front direction.

[0065] In related technologies, the compressor compartment 6 of the refrigeration equipment is usually located at the bottom of the cabinet and near the rear, while the evaporator 24 is usually located at the back of the refrigeration equipment. The compressor compartment 6 and the evaporator 24 occupy the rear space of the cabinet, resulting in a smaller drawer depth.

[0066] In this embodiment, the refrigeration compartment 211 is located at the bottom, and the compressor compartment 6 is at least partially located in front of the refrigeration compartment 211. This reduces its occupancy of the depth space of the rear storage compartment 121, thereby allowing for the design of deeper storage drawers and effectively increasing the usable internal volume of the equipment.

[0067] The bottom insulation layer 23 can reduce thermal interference between the compressor compartment 6 and the refrigeration compartment 211.

[0068] The press support plate 3 can be connected to the main housing 21 to form an independent module, and then the independent module can be assembled with the housing; or it can be connected to the main housing 21 after the integrated component 2 is assembled with the housing to form the press chamber 6.

[0069] The compressor 4 and the heat dissipation assembly are located inside the compressor compartment 6, which may be located at the bottom of the inner liner 12 and at least partially at the front of the refrigeration compartment 211.

[0070] The heat dissipation components include heat dissipation devices such as condensers, cooling fans, rear condensers or decondensation pipes.

[0071] Among them, a heat insulation component 295 is provided between the back of the inner liner 12 and the outer shell 11. The thermal conductivity of the heat insulation component 295 is lower than that of the bottom insulation layer 23. An insulation layer is provided between the side wall of the inner liner 12 and the outer shell 11. The insulation layer can be made of the same material as the heat insulation component 295 or the same material as the bottom insulation layer 23.

[0072] Among them, the heat insulation component 295 can be a vacuum insulation board (VIP) or other materials with a lower thermal conductivity than the conventional polyurethane foam used in the bottom insulation layer 23, which can greatly improve the heat insulation performance of the rear wall of the box and reduce the thickness of the insulation layer of the refrigeration equipment.

[0073] The refrigeration system mainly includes an evaporator 24, a compressor 4, and a heat dissipation assembly. The evaporator 24 is located in the refrigeration compartment 211 and is used to absorb heat from within the compartment. The compressor 4 and the heat dissipation assembly are located within the compressor compartment 6, which is situated at the bottom of the inner liner 12 and at least partially at the front of the refrigeration compartment 211. The heat dissipation assembly includes a condenser and a cooling fan, and is used to dissipate the heat carried by the refrigerant into the environment.

[0074] According to the refrigeration equipment provided in the embodiments of this application, on the one hand, by setting the integrated component 2 outside the inner liner 12, the inner liner 12 can be formed with a flat bottom plate, simplifying the structure of the inner liner 12 and reducing production costs; at the same time, the integrated component 2 integrates the evaporator 24 and the refrigeration chamber 211. When the compressor support plate 3 is pre-installed on the integrated component 2, the compressor chamber 6, the compressor 4 and the heat dissipation component can also be integrated. It can be used as an independent pre-installed module. When assembling the whole machine, only the integrated component 2 needs to be assembled and connected to the inner liner 12, which significantly improves production efficiency; on the other hand, the compressor chamber 6 is at least partially set on the front side of the refrigeration chamber 211, which can reduce its occupation of the depth space of the rear storage compartment 121, thereby allowing for the design of deeper storage drawers and effectively increasing the usable volume inside the equipment.

[0075] In some embodiments, the housing further includes an outer shell 11 and an inner liner 12, the inner liner 12 being disposed inside the outer shell 11, and the integrated component 2 being detachably connected to the outer shell 11.

[0076] The main housing 21 and the outer housing 11 are detachably connected.

[0077] For example, the housing 11 and the integrated component 2 can be connected by a snap-fit: a snap-fit ​​structure is provided on the bottom edge of the housing 11, and a corresponding slot is provided on the integrated component 2, so that a quick connection can be achieved by the cooperation of the snap-fit ​​and the slot.

[0078] For example, the housing 11 and the integrated component 2 can be connected by screws: corresponding mounting holes are provided at the connection edge of the housing 11 and the integrated component 2, and reliable fixing is achieved by screws.

[0079] For example, the housing 11 and the integrated component 2 can be connected by a slide rail: a slide rail is provided at the bottom of the housing 11, and the integrated component 2 is positioned and connected by being pushed into the slide rail.

[0080] For example, the housing 11 and the integrated component 2 can be connected by quick-release couplings: quick-release couplings are used at refrigerant lines and electrical connections to facilitate rapid separation and connection.

[0081] In this embodiment, the following multi-directional effects can be achieved: when the integrated component 2 or the housing needs to be repaired or replaced, it can be quickly disassembled, greatly reducing maintenance costs and time; the modular design and detachable connection method are conducive to improving the assembly efficiency of the production line; different specifications of integrated components 2 can be flexibly replaced according to different models and configuration requirements, enhancing design flexibility; maintenance personnel can replace parts without damaging the overall structure, improving the quality of after-sales service; the detachable design makes cleaning and maintenance of the storage room 121 and the refrigeration compartment 211 more convenient and thorough, facilitating cleaning and maintenance.

[0082] In some embodiments, such as Figure 7 As shown, the outer casing 11 is provided with a first snap-fit ​​member 111, and the integrated component 2 is provided with a second snap-fit ​​member 26 that is rotatably snap-fitted to the first snap-fit ​​member 111. When the first snap-fit ​​member 111 and the second snap-fit ​​member 26 are snap-fitted, the integrated component 2 rotates relative to the first snap-fit ​​member 111 to make the integrated component 2 and the outer casing 11 seal together.

[0083] During installation, the second snap-fit ​​component 26 is first snapped into the first snap-fit ​​component 111, and then the integrated component 2 is rotated relative to the first snap-fit ​​component 111. During this rotation, the integrated component 2 is gradually pressed against the outer shell 11, and finally a reliable sealed connection is achieved.

[0084] For example, the first snap-fit ​​component 111 is a snap post disposed on the lower front beam 292 of the outer casing 11, and the second snap-fit ​​component 26 is a buckle disposed on the front end of the bottom steel plate of the integrated component 2. During installation, the buckle is first hooked onto the snap post, and then the integrated component 2 is rotated upward with the hooking point as the rotation center, so that the sealing strip disposed around the integrated component 2 is fully pressed against the bottom of the outer casing 11 to form an effective seal.

[0085] In this embodiment, the integrated component 2 is quickly installed by means of rotation and snap-fit, which simplifies the installation process and greatly improves the assembly efficiency. During the rotation, the sealing strip is uniformly compressed to form a reliable sealing interface, which effectively reduces cold air leakage. At the same time, the snap-fit ​​structure provides accurate installation positioning for the integrated component 2 and improves the alignment accuracy of each component. When disassembly is required, the integrated component 2 can be easily removed by rotating it in the opposite direction, which greatly facilitates subsequent maintenance.

[0086] In some embodiments, the housing 11 is provided with a first fitting at one end away from the first snap-fit ​​member 111, and the integrated component 2 is provided with a second fitting at one end away from the second snap-fit ​​member 26. The first fitting and the second fitting are fastened together.

[0087] The front side of the integrated component 2 is connected to the outer shell 11 by the second snap-fit ​​26 and the first snap-fit ​​111, and the rear side is fastened by the first and second fittings. The connection between the front and rear improves the stability of the connection between the integrated component 2 and the housing.

[0088] For example, the first and second assemblies are fastened with screws. The first assembly is an array of threaded holes located at the rear of the housing 11, and the second assembly is an array of through holes located at the rear of the integrated component 2. The fastening connection is achieved by screwing the screws through the through holes into the threaded holes. For example, the threaded holes adopt self-tapping threads or pre-embedded nut structures.

[0089] For example, the first and second components are quick-release buckles. The first component is a buckle seat set on the housing 11, and the second component is an elastic claw set on the integrated component 2. The claw and the buckle seat are elastically engaged to achieve quick fastening. The claw is designed with a release mechanism for easy disassembly.

[0090] For example, the first and second assemblies are magnetically assisted structures. The first assembly is a permanent magnet array disposed on the housing 11, and the second assembly is a magnetic guide plate disposed on the integrated component 2. They are positioned and kept in a pressed state by magnetic force, and are used in conjunction with other mechanical locking methods.

[0091] The integrated component 2 is provided with a rotating snap-fit ​​structure between itself and the housing 11, and further includes an auxiliary fastening device. After the integrated component 2 is rotated into place, it is finally fixed by the fastening connection of the first and second fittings.

[0092] In this embodiment, a dual fixing method of rotational snap-fit ​​and auxiliary fastening is used to achieve double fixing protection, which improves the firmness and reliability of the integrated component 2 installation, reduces the loosening of the integrated component 2 during use, and improves the structural stability of the whole machine. At the same time, the initial positioning and pre-sealing are achieved by rotational snap-fit ​​first, and the final fixing is completed by auxiliary fastening, which makes the installation process smoother and optimizes the installation process. Moreover, the auxiliary fastening device can provide additional clamping force to ensure that the sealing strip is uniformly and fully compressed, thereby improving the sealing performance. In addition, the auxiliary fastening device usually has an adjustment function, which can fine-tune the final position of the integrated component 2 and improve the installation accuracy.

[0093] In some embodiments, such as Figure 6 and Figure 8 As shown, the main housing 21 has an opening, and the cooling chamber 27 has a flange 271 that folds outward toward the cooling compartment 211. The flange 271 is sealed to the main housing 21 to close the opening.

[0094] The refrigeration chamber 27 (a core component for housing the evaporator 24 and forming the inner wall of the refrigeration compartment 211) has a flange 271 that extends horizontally (or nearly horizontally) outward toward the outside of the refrigeration compartment 211 at its top edge or opening edge. This flange 271 surrounds the entire opening perimeter of the refrigeration chamber 27, forming a flange-like connecting surface.

[0095] During assembly, the cooling element 27 is inserted through the opening of the main housing 21. After insertion, the flange 271 of the cooling element 27 covers and adheres to the inner edge, outer edge, or end face of the main housing 21 surrounding the opening.

[0096] For example, the flange 271 and the main housing 21 can be sealed together by welding, gluing or bolting with a sealing element.

[0097] In this embodiment, the outwardly turned flange 271 provides a wide, continuous sealing engagement area. Whether welding, applying adhesive, or placing a gasket, the large contact surface increases the uniformity of the sealing medium's full compression, significantly improving the redundancy and long-term reliability of the seal, and effectively reducing refrigerant leakage and external moisture intrusion.

[0098] Meanwhile, the flange 271 itself is a reinforcing structure for the edge of the refrigeration chamber 27. When it is sealed and connected to the more robust main shell 21, it is equivalent to adding a reinforced annular frame at the opening of the refrigeration compartment 211. This greatly enhances the area's ability to resist internal pressure, external impacts (such as transportation vibrations), and the huge expansion stress during the foaming process, reducing deformation or cracking at the connection.

[0099] In some embodiments, such as Figure 2 and Figure 5 As shown, the inner liner 12 forms a storage compartment 121. The inner liner 12, the outer shell 11, and the refrigeration top cover 28 form a first return air vent 13 that connects the storage compartment 121 and the refrigeration chamber 211. The vertical projection of the first return air vent 13 is located within the vertical projection of the compressor chamber 6.

[0100] The front side of the vertical projection of the refrigeration compartment 211 at least partially overlaps with the vertical projection of the compressor compartment 6.

[0101] The vertical projection of the first return air vent 13 is located within the vertical projection of the compressor compartment 6, indicating that the first return air vent 13 is located in front of the vertical projection of the refrigeration compartment 211. Since the front end of the evaporator 24 is close to the front end of the refrigeration compartment 211, a directional return airflow can be formed, allowing the return air to blow directly onto the front surface of the evaporator 24, or guiding the return airflow towards the evaporator 24, so that the return airflow flows from the front end of the evaporator 24 to the rear end of the evaporator 24, prolonging the heat exchange time between the return airflow and the evaporator 24, and enhancing the heat exchange effect.

[0102] In some embodiments, such as Figure 5 As shown, the main housing 21 has a first ventilation opening 212. The refrigeration equipment also includes a return air duct 14. The return air duct 14 connects the first ventilation opening 212 and the second return air opening 213 of the refrigeration chamber 211. The portion of the return air duct 14 that connects the first ventilation opening 212 and the second return air opening 213 of the refrigeration chamber 211 is located inside the main housing 21.

[0103] The inner liner 12 forms a first compartment and a second compartment, which are storage compartments 121 used for storing items. The first compartment, the second compartment, and the refrigeration compartment 211 are distributed sequentially along the height direction. The first compartment returns air to the refrigeration compartment 211 through the return air duct 14, and the second compartment returns air to the refrigeration compartment 211 through the first return air inlet 13.

[0104] The return air duct 14 includes a first return air section and a second return air section. The first return air section connects the first room and the first vent 212, and the second return air section is installed in the main shell 21 and connects the first vent 212 and the second return air vent 213.

[0105] For example, the second return air vent 213 can be located at the front of the refrigeration chamber 211 so as to send the return air to the front end of the evaporator 24, so that the return air flow flows from the front end of the evaporator 24 to the rear end of the evaporator 24, thereby prolonging the heat exchange time between the return air flow and the evaporator 24 and enhancing the heat exchange effect.

[0106] In this embodiment, the second return air section is located outside the refrigeration compartment 211, but between the main shell 21 and the refrigeration tank 27. That is, at least part of the second return air section and the return air heat exchange component are located inside the bottom insulation layer 23. In other words, the second return air section of the return air duct 14, at least part of the return air heat exchange component and the bottom insulation layer 23 are all integrated between the main shell 21, the refrigeration tank 27 and the cabin cover 22, which improves the concentration of the functions of the integrated component 2.

[0107] The first return air section can be located inside the inner liner 12 and on the rear wall of the inner liner 12, or the first return air section can be located outside the inner liner 12, both of which can achieve the return air function of connecting the first compartment and the first ventilation opening 212.

[0108] In this embodiment, the first return air section can be used as an independent component and precisely connected to the first vent 212 of the integrated component 2 during final assembly. There is no need to install the second return air section, which facilitates reliable sealing and reduces cold air leakage.

[0109] In some embodiments, such as Figure 6 As shown, the second return air vent 213 is located on the side wall of the refrigeration chamber 27 along the left and right directions. The vertical orthographic projection of the second return air vent 213 is located in front of the vertical orthographic projection of the refrigeration chamber 211. The vertical orthographic projection of the second return air vent 213 is at least partially located within the vertical orthographic projection of the compressor chamber 6.

[0110] The second return air inlet 213 is located on the front side of the refrigeration chamber 211. The outlet of the return air duct 14 is connected to the second return air inlet 213 of the refrigeration chamber 211. The air outlet of the refrigeration chamber 211 is located on the rear side of the refrigeration chamber 211. The front end of the evaporator 24 is close to the front side of the refrigeration chamber 211, and the rear end of the evaporator 24 is close to the rear side of the refrigeration chamber 211. That is, the second return air inlet 213 of the refrigeration chamber 211 faces the front end of the evaporator 24, and the air outlet of the refrigeration chamber 211 faces the rear end of the evaporator 24, forming a directional return airflow.

[0111] In this embodiment, the second return air inlet 213 of the refrigeration chamber 211 is positioned at the front, and the air outlet is positioned at the rear of the refrigeration chamber 211, forming a directional return airflow. This allows the return air to blow directly onto the surface of the evaporator 24, or guide the return airflow toward the evaporator 24, so that the return airflow flows from the front end of the evaporator 24 to the rear end of the evaporator 24, thereby prolonging the heat exchange time between the return airflow and the evaporator 24 and enhancing the heat exchange effect.

[0112] In some embodiments, the second return air vent 213 includes a first section and a second section distributed along the front and rear. The vertical orthographic projection of the second section is located in front of the vertical orthographic projection of the evaporator 24, and the vertical orthographic projection of the first section is located in front of the vertical orthographic projection of the refrigeration compartment 211, and at least partially located behind the vertical orthographic projection of the compressor compartment 6.

[0113] The vertical orthographic projection of the second section is located in front of the vertical orthographic projection of the evaporator 24, and the vertical orthographic projection of the first section is located in front of the vertical orthographic projection of the refrigeration compartment 211, and at least partially behind the vertical orthographic projection of the compressor compartment 6.

[0114] In other words, the vertical orthographic projection of the first interval is located in front of the vertical orthographic projection of the evaporator 24, and the second interval is located behind the first interval and its vertical orthographic projection overlaps with the vertical orthographic projection of the evaporator 24 in the left-right direction.

[0115] The vertical projection of the second section is located in front of the vertical projection area of ​​the evaporator 24. This means that the vertical projection of the first section is located in front of the vertical projection of the evaporator 24. The airflow from the second section will directly act on the heat exchange surface of the front part of the evaporator 24, and the airflow from the first section will directly act on the front heat exchange surface of the evaporator 24. This allows the return air drawn from the storage chamber 121 to directly impact the core heat exchange area of ​​the evaporator 24 with the shortest path and minimal energy loss, thereby maximizing heat exchange efficiency.

[0116] The first section is located above the narrow space between "behind the compressor compartment 6" and "in front of the refrigeration compartment 211". This is the "negative space" or "tunnel area" formed in the upper front of the refrigeration compartment 211 after the compressor compartment 6 is placed in front. This area is difficult to utilize in traditional designs.

[0117] This embodiment significantly increases the effective flow area of ​​the return air vent by extending the first section of the air outlet to this area, without increasing the external dimensions of the housing or the volume of the refrigeration chamber 211. This helps to reduce the inlet air velocity, reduce wind resistance and airflow noise, and make the airflow distribution more stable.

[0118] Some of the return air first enters through the first section located further forward. Before reaching the evaporator 24, it may undergo slight pre-cooling and velocity equalization in the first section in front of the refrigeration compartment 211. That is, the first section can serve as an airflow buffer and pre-cooling zone, which helps to improve the heat exchange uniformity when it flows through the evaporator 24, reduce airflow dead zones, and improve the compactness of the layout.

[0119] In some embodiments, the return air vent of the refrigeration compartment 211 is located on the front side of the refrigeration compartment 211 and faces the drain outlet, so as to utilize the heat of the return air for defrosting and reduce the risk of drain outlet blockage.

[0120] The return air vent and the front end of the evaporator 24 have at least the following relative positional relationship: Firstly, the center of the air outlet is positioned in front of the orthogonal projection of the evaporator 24 at the bottom of the inner liner 12.

[0121] Among them, the orthographic projection of the air outlet at the bottom of the inner liner 12 is closer to the front of the refrigeration compartment 211.

[0122] For example, the air outlet is located directly in front of the evaporator 24, or in front to the left of the evaporator 24, or in front to the right of the evaporator 24.

[0123] In this embodiment, the return air must "cross" the front end of the evaporator 24 before entering the evaporator 24, thus prolonging the airflow contact time and improving heat exchange efficiency; reducing the amount of return air that does not fully flow through the evaporator 24 before directly entering the supply air duct; and ensuring that the front end of the evaporator 24 is prone to frosting, this design allows the return air to preferentially impact the frosted area. Secondly, the center of the air outlet is on the same plane as the front end of the evaporator 24.

[0124] The central axis of the air outlet is on the same plane as the front end of the evaporator 24, that is, the air outlet direction is parallel to the front end of the evaporator 24.

[0125] In this embodiment, the return airflow vertically impacts the front end of the evaporator 24, reducing eddies and improving the convective heat transfer coefficient; at the same time, it can increase the uniformity of the return airflow distribution.

[0126] Third, the front projection of the air outlet and the front end of the evaporator 24 onto the side wall of the inner liner 12 distributed in the left and right directions at least partially overlaps.

[0127] There is an overlapping area between the air outlet and the front end of the evaporator 24 on the side wall of the inner liner 12. That is, when viewed from the side, the air outlet and the front end of the evaporator 24 overlap.

[0128] In this embodiment, the return air and evaporator 24 can be maximized within a limited depth, improving space compactness: increasing the area covered by the return airflow at the front edge of the evaporator 24 and reducing the dead angle of contact between the return airflow and the evaporator 24.

[0129] Among them, the contact dead angle of the evaporator 24 includes the areas on both sides of the evaporator 24 that are prone to frost accumulation.

[0130] In some embodiments, such as Figure 9 and Figure 10 As shown, the refrigeration equipment also includes a decondensation pipe 5, which is located at the front end of the inner liner 12; the integrated assembly 2 also includes a baffle plate 291 and a lower front beam 292, the lower front beam 292 extends downward relative to the top cover of the main housing 21, the baffle plate 291 and the lower front beam 292 define a pipe passage 293, the decondensation pipe 5 passes through the pipe passage 293 and the engine compartment cover 22 and is connected to the compressor 4.

[0131] The main shell 21, the lower front beam 292, the cooling liner 27, and the engine compartment cover 22 together form an insulation space for the bottom insulation layer 23.

[0132] The defrosting pipe 5 is usually connected to the discharge end of the compressor 4 (or the outlet of the condenser), and high-temperature and high-pressure gaseous refrigerant flows inside it.

[0133] The decondensation pipe 5 is located at the front end of the inner liner 12, specifically around the door frame or inside the front wall panel of the inner liner 12. Its function is to use the heat of the refrigerant in the decondensation pipe 5 to heat the "cold bridge" area at the front of the cabinet that is most likely to come into contact with the external humid and hot air, so that its surface temperature is higher than the ambient dew point temperature, thereby effectively preventing condensation on the door frame and the front of the cabinet.

[0134] The lower front beam 292 is a structural component at the front of the integrated assembly 2. It extends downward (i.e. towards the ground) relative to the top cover portion of the main housing 21, forming the lower edge or support structure of the front face of the integrated assembly 2.

[0135] The shield 291 is installed on the rear side of the lower front beam 292 and works in conjunction with the lower front beam 292, with a specific gap between them or forming a tubular, longitudinal "through-duct channel 293". This through-duct channel 293 provides a concealed path for the vent pipe 5 and wiring harness to access the interior of the integrated assembly 2 from below / front.

[0136] The connection path of the decondensation pipe 5 is designed as follows: starting from the heating section of the decondensation pipe 5 located at the front end of the inner liner 12, it passes downward into the pipe passage 293 defined by the baffle plate 291 and the lower front beam 292, enters the integrated component 2 area through the pipe passage 293, and then passes through the reserved hole or channel on the engine compartment cover 22, and finally connects to the compressor 4 located in the compressor compartment 6.

[0137] In this embodiment, the condensation removal pipe 5 can be both aesthetically pleasing and safely concealed: through a specially designed pipe-through channel 293, the exposed condensation removal pipe 5 (usually a copper or aluminum pipe) is completely hidden and protected inside the structural components, reducing the number of pipes exposed at the front or side of the equipment and improving the neatness and high-end feel of the product's appearance. At the same time, the channel also protects the pipes from external impacts or wear.

[0138] Meanwhile, the assembly process and path fixation are optimized: the pipe-through channel 293 provides a preset and unique guide path for the installation of the decondensation pipe 5. During final assembly, the operator can easily pass the decondensation pipe 5 through the channel, just like "threading a needle," which simplifies the pipe laying process and naturally achieves the neat arrangement and fixation of the pipeline, improving assembly efficiency and consistency.

[0139] Meanwhile, structural protection and system reliability are enhanced: the channel formed by the shielding plate 291 and the lower front beam 292 provides physical protection and thermal insulation for the condensation pipe 5. This reduces direct high-temperature contact between the condensation pipe 5 and potentially heat-sensitive plastic parts or insulation materials, and also prevents it from being squeezed by other components. The clearly defined wiring path reduces stress concentration points caused by haphazard pipe layout, improving long-term operational reliability.

[0140] Meanwhile, it facilitates centralized maintenance and inspection: although the piping is concealed, its main route is confined to a clearly defined channel. When the refrigeration system needs maintenance, maintenance personnel can quickly locate and inspect this section of piping based on the structural drawings, ensuring traceability and convenience of maintenance.

[0141] In some embodiments, the vent pipe 5 is located at the front end of the inner liner 12 and on the side away from the compressor chamber 6.

[0142] The compressor compartment 6 is positioned below the storage compartment 121 and at the front of the housing. This layout allows the waste heat generated by the compressor compartment 6 to be naturally transferred to the area above and around it, especially the inner liner 12 area below the front of the refrigeration equipment.

[0143] The inner liner 12, located near the compressor chamber 6, can directly or indirectly utilize the waste heat generated by the operation of the compressor chamber 6 because it is adjacent to or close to the front compressor chamber 6. This heat can maintain the surface temperature of the chamber in this area above the dew point temperature of the ambient air, thus achieving the anti-condensation effect on the "heat source side".

[0144] The front end of the inner liner 12, which is far from the heat source (compressor chamber 6), cannot effectively obtain its waste heat and still has the risk of condensation in high temperature and high humidity environments.

[0145] In this embodiment, a decondensation pipe 5 is installed only on the front end of the inner liner 12, on the side furthest from the compressor compartment 6. On the side closer to the compressor compartment 6, no decondensation pipe 5 is specifically installed; natural decondensation prevention relies on the waste heat from the compressor compartment 6. This means reducing a section of high-temperature, high-pressure refrigerant piping that requires the compressor 4 to perform work for heating. This directly reduces some of the ineffective load on the compressor 4, reduces system energy consumption, and improves the overall energy efficiency ratio. Simultaneously, it reduces the length of the decondensation pipe 5 and the corresponding fasteners and insulation materials, simplifying the piping layout of the refrigeration system and reducing material costs and assembly complexity.

[0146] In some embodiments, the inner liner 12 has an opening, and the condensation pipe 5 includes a first section 51 and a second section 52. The first section 51 extends along the height direction of the inner liner 12 and is disposed on the side of the inner liner 12, and the second section 52 extends along the left and right direction and is disposed on the side of the inner liner 12 away from the compressor chamber 6.

[0147] The inner liner 12 forms a storage compartment 121, which has an opening at the front and a door for closing the opening.

[0148] Among them, the vent pipe 5 is designed to include two sections with different directions, based on the structure of the front end of the inner liner 12, and the whole is L-shaped.

[0149] The first segment 51 extends roughly along the height (i.e., vertical direction) of the inner liner 12. It is located on the side of the inner liner 12, specifically at the vertical edge area where the front face of the inner liner 12 meets the side wall. This segment is mainly responsible for heating and preventing condensation in the lateral vertical area at the front of the cabinet. The first segment 51 can be located on the left or right side of the front end of the inner liner 12.

[0150] The second section 52 begins at the end of the first section 51 and extends roughly in a left-right (i.e., horizontal) direction. It is specifically positioned on the side of the inner liner 12 away from the compressor compartment 6. For example, if the compressor compartment 6 is located below the equipment, this second section 52 decondensation pipe 5 will be arranged on the upper edge of the door frame at the front end of the inner liner 12. This section is mainly responsible for providing focused heating and decondensation prevention to the upper or lower horizontal areas away from the heat source.

[0151] In this embodiment, by concentrating the decondensation pipes 5 along the L-shaped path with the highest risk of condensation, an equivalent or even better overall anti-condensation effect can be achieved with a shorter pipe length. Compared to the traditional U-shaped or rectangular arrangement around the entire door frame, this solution significantly reduces the amount of high-temperature refrigerant used and the heat loss of the pipes, resulting in a more prominent energy-saving effect.

[0152] In some embodiments, the inner liner 12 includes a first liner and a second liner distributed along the height direction. The bottom front side of the second liner is not provided with a decondensation pipe 5, and a compressor chamber 6 is provided on the lower front side of the second liner.

[0153] The first and second chambers can correspond to two independent compartments, such as a refrigerator chamber and a freezer chamber. The front side of the first and second chambers requires active heating, and a decondensation pipe 5 can be installed to prevent condensation. The bottom front side of the second chamber (such as the freezer chamber) is close to the natural heat source (compressor compartment 6) and does not require active heating, so a decondensation pipe 5 can be omitted.

[0154] If the compressor compartment 6 is located below the equipment, then the second section 52 decondensation pipe 5 will be arranged at the upper and lower edges of the door frame at the front end of the first chamber, and at the upper edge of the door frame of the second chamber. The lower edge of the door frame of the second chamber is close to the compressor compartment 6, and can achieve natural decondensation prevention by relying on the waste heat of the compressor compartment 6, reducing part of the ineffective load of the compressor 4 and improving the overall energy efficiency ratio.

[0155] In some embodiments, such as Figure 3 As shown, the integrated component 2 also includes a cabin side panel 294, and the cabin side panel 294, the cabin cover 22 and the main shell 21 together form the compressor cabin 6; the cabin side panel 294 overlaps at least partially with the main shell 21, and the overlapping area of ​​the cabin side panel 294 and the main shell 21 is sealed together.

[0156] The front cover plate of the main shell 21, the side panel 294 of the engine compartment, and the engine compartment cover plate 22 together form the compressor compartment 6. The front cover plate of the main shell 21 may be provided with heat dissipation holes to dissipate heat from the compressor compartment 6.

[0157] The cabin side panel 294 overlaps at least partially with the main shell 21. For example, a portion of the cabin side panel 294 covers the outer or inner surface of the main shell 21, or a portion of the structure of the main shell 21 may be embedded in a slot in the cabin side panel 294.

[0158] In the overlapping area of ​​the cabin side panel 294 and the main shell 21, the cabin side panel 294 and the main shell 21 are fixed together by a sealed connection.

[0159] For example, the cabin side panel 294 and the main shell 21 can be fixed together by welding, gluing, bolt / screw connection supplemented by sealing gaskets or other sealing connection methods.

[0160] In this embodiment, the overlapping area structure provides a wide, continuous sealing surface, which is significantly superior to line contact or point contact. Regardless of whether welding, adhesive bonding, or gasket sealing is used, the large contact area ensures that the sealing medium is uniformly stressed, effectively resisting the outward penetration of oil mist, moisture, and pressure fluctuations that may exist in the compressor chamber 6, and also preventing the entry of external dust and moisture, thus achieving a highly reliable lateral seal.

[0161] Meanwhile, the overlapping area is equivalent to adding a reinforcing liner or double-layer structure at the connection between the cabin side panel 294 and the main shell 21. This greatly enhances the bending, torsional and impact resistance of the connection part, enabling the side wall of the compressor cabin 6 to better withstand the weight of the internal equipment, operating vibration and stress during transportation, and improve the structural robustness of the entire integrated assembly 2.

[0162] Meanwhile, the overlapping area provides a clear and easily aligned positioning reference for assembly. During assembly, the operator can first align and fit the overlapping portion of the nacelle side panel 294 with the main shell 21 before fixing it, reducing assembly difficulty and improving the accuracy of the assembly position. This is crucial for ensuring the installation space and piping interface accuracy of internal components (such as the compressor 4) in the compressor compartment 6.

[0163] Meanwhile, after the sealing connection, from the outside, the joint between the cabin side panel 294 and the main shell 21 is smooth and tight, with no obvious gaps or misalignments, which enhances the visual integrity and craftsmanship of the bottom of the product. The internal seal also prevents possible condensation or dirt from accumulating in the gaps.

[0164] In some embodiments, a heat insulation element 295 is provided on the rear side of the integrated component 2, and the thermal conductivity of the heat insulation element 295 is lower than that of the bottom insulation layer 23.

[0165] The thermal insulation component 295 is disposed on the inner side of the rear wall of the main housing 21 to improve the thermal insulation performance of the rear side of the integrated assembly 2. The thermal insulation component 295 can be attached to the inner side of the rear wall of the main housing 21.

[0166] Among them, the heat insulation component 295 can be a vacuum insulation board (VIP) or other materials with a lower thermal conductivity than the conventional polyurethane foam used in the bottom insulation layer 23, which can greatly improve the heat insulation performance of the rear wall of the box and reduce the thickness of the insulation layer of the refrigeration equipment.

[0167] In some embodiments, the refrigeration chamber 211 includes a first sub-chamber 214 and a second sub-chamber 215 distributed along the front and rear. An evaporator 24 is disposed in the second sub-chamber 215. The second sub-chamber 215 is connected to the return air vent of the refrigeration chamber 211 through the first sub-chamber 214. The vertical orthographic projection of the first sub-chamber 214 is located within the vertical orthographic projection of the refrigeration chamber 211, and the vertical orthographic projection of the second sub-chamber 215 is located behind the vertical orthographic projection of the refrigeration chamber 211.

[0168] The second sub-compartment 215 is connected to the return air vent of the refrigeration compartment 211 through the first sub-compartment 214, so that the return airflow path is: return air vent, first sub-compartment 214 and second sub-compartment 215 in sequence.

[0169] The vertical projection of the first sub-cabin 214 lies entirely within the vertical projection area of ​​the compressor compartment 6. This layout makes full use of the space above the compressor compartment 6.

[0170] The vertical projection of the second sub-compartment 215 is located behind the vertical projection of the compressor compartment 6. This completely separates the core heat exchange area from the high-temperature compressor 4 area in space.

[0171] In this embodiment, the first sub-compartment 214 serves as a buffer and pre-treatment channel before the airflow enters the evaporator 24. Its layout above the compressor compartment 6 allows for the use of the low-temperature sidewall of the compressor compartment 6 (or through thermal insulation design) to pre-cool the intake air, achieving airflow pre-cooling and thermal isolation. At the same time, it physically isolates the direct radiative heating of the intake air by the high temperature of the compressor 4, reducing the heat load of the evaporator 24.

[0172] Meanwhile, by placing the air intake channel (first sub-compartment 214) above the compressor compartment 6 and the core heat exchange area (second sub-compartment 215) behind it, a three-dimensional staggered arrangement of the refrigeration flow channel and the heat dissipation area of ​​the compressor 4 is achieved. This not only makes efficient use of space, but also achieves active isolation between hot and cold zones through structural design, improving the overall energy efficiency of the system and optimizing space utilization and thermal management.

[0173] Meanwhile, the airflow, guided and buffered by the first sub-compartment 214, can enter the evaporator 24 of the second sub-compartment 215 more smoothly and evenly, improving the uniformity of airflow, which helps to improve the heat exchange efficiency and service life of the evaporator 24 and reduce the problem of local frost caused by uneven airflow.

[0174] In some embodiments, such as Figure 4 As shown, the refrigeration compartment 211 also includes a third sub-compartment located between the first sub-compartment 214 and the second sub-compartment 215. At least a portion of the vertical orthographic projection of the first sub-compartment 214 is located within the vertical orthographic projection of the refrigeration compartment 211, and the flow cross-sectional area of ​​the third sub-compartment gradually increases from front to back.

[0175] The return airflow path is as follows: return air inlet, first sub-compartment 214, third sub-compartment, and second sub-compartment 215. The third sub-compartment is located between the first sub-compartment 214 and the second sub-compartment 215, serving as an airflow transition and distribution area.

[0176] The flow cross-sectional area of ​​the third sub-compartment is designed to gradually increase from front to back, forming a gradually expanding flow channel.

[0177] In this embodiment, the first sub-compartment 214 serves as the first chamber into which the airflow enters, and can perform preliminary stabilization and distribution of the air drawn in from the return air vent. The gradually expanding design of the third sub-compartment can effectively reduce the airflow velocity and make the airflow more uniform and stable before entering the second sub-compartment 215 where the evaporator 24 is located, thereby significantly improving the overall heat exchange efficiency of the evaporator 24 and avoiding local overcooling or frost formation.

[0178] In this embodiment, the gradually expanding third sub-compartment causes the airflow velocity from the first sub-compartment 214 to gradually decrease and the static pressure to increase. This helps the airflow achieve a more uniform velocity and pressure distribution across the flow cross-section before entering the heat exchange area of ​​the evaporator 24 in the second sub-compartment 215, creating ideal conditions for efficient and uniform heat exchange in the evaporator 24, and effectively reducing the risk of dead airflow zones and localized frost formation.

[0179] Meanwhile, the gradually expanding structure can smoothly guide the airflow direction, reduce unstable flows such as eddies and turbulence caused by abrupt changes in the flow cross section, optimize the flow field stability, thereby reducing airflow noise and energy loss, and improving the working efficiency and stability of the fan system.

[0180] Meanwhile, the layout of the first sub-compartment 214, located within the compressor compartment 6 projection, remains unchanged, continuing to utilize unused space and provide thermal insulation. The newly added third sub-compartment, serving as a functional flow channel transition area, further improves the rationality of the airflow path from the intake to the core heat exchange area, strengthens spatial coupling and thermal insulation, and enables more precise management of hot and cold zones.

[0181] Meanwhile, by implementing a refined design of the airflow path of "pre-treatment (first sub-compartment 214) → uniform flow transition (third sub-compartment) → core heat exchange (second sub-compartment 215)," the aerodynamic performance inside the refrigeration compartment 211 is systematically improved, thereby directly enhancing the heat exchange efficiency of the evaporator 24 and the overall energy efficiency ratio of the refrigeration system, while also strengthening the long-term reliability of the system operation.
