Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a refrigeration device. Background Technology

[0002] Currently, in existing refrigerator designs, the compressor compartment houses a control box, filter, and frequency converter. The control box contains a control board with main control and display functions. Wires connect the power supply to the filter, the filter to the control board, the control box to the frequency converter, and the frequency converter to the compressor. During installation, the compressor, control box, filter, and frequency converter must be installed separately in the compartment, and then each component is individually wired. Because installing these components in the compartment requires arranging and connecting numerous wire harnesses, and the limited space within the compartment makes the assembly process cumbersome, resulting in low assembly efficiency and high assembly costs.

[0022] In some embodiments, the second control box includes a first box portion and a second box portion, which are arranged sequentially from the direction away from the compressor to the direction closer to the compressor. The length of the second box portion in the height direction is greater than the length of the first box portion in the height direction.

[0037] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0038] In the description of this utility model, it should be understood that when an element is referred to as "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to or indirectly connected to the other element. The terms "mounted," "connected," and "attached" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0039] In the description of this utility model, it should be understood that the terms "height," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0041] See Figure 1-2 As shown, this utility model embodiment provides a refrigeration device 100, including a cabinet 1 and a door 5. The cabinet 1 has a pick-up and put-out opening (not shown in the figure); the door 5 is connected to the cabinet 1 and can move relative to the cabinet 1 to open and close the pick-up and put-out opening.

[0042] The cabinet 1 is generally a rectangular frame structure, comprising a cabinet shell (not shown in the figure) and a cabinet liner (not shown in the figure). The cabinet liner is located inside the cabinet shell, and a foamed space (not shown in the figure) is formed between the cabinet liner and the cabinet shell. The foamed space is used to install other components of the refrigeration equipment 100 and to form a foamed insulation layer. The cabinet shell provides protection and support for the cabinet liner. A refrigeration compartment is formed inside the cabinet liner for storing food. An access port is located on one side of the refrigeration compartment for easy access to items inside. The door 5 is rotatably connected to the cabinet shell of the cabinet 1; for example, the door 5 can be rotatably connected to the cabinet shell or slidably connected.

[0043] In some embodiments, the refrigeration device 100 further includes a refrigeration system (not shown) and an air supply system (not shown), which are electrically connected to a power supply component. The power supply component is used to supply power to the various components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0044] The refrigeration system is installed inside cabinet 1 and is used to supply cold air to the refrigeration compartments inside the cabinet. A refrigeration system typically refers to a closed system composed of components such as compressor 2, evaporator (not shown in the figure), condenser (not shown in the figure), dryer filter (not shown in the figure), return pipe (not shown in the figure), and throttling device (not shown in the figure), as well as refrigerant. Each component is distributed in different positions within cabinet 1 according to its structural characteristics to meet its corresponding functional requirements. The working process of the refrigeration system mainly includes compression, condensation, throttling, and evaporation. The compression process is as follows: After the power cord of the refrigeration equipment 100 is plugged in, with the thermostat contacts closed, compressor 2 starts working. Low-temperature, low-pressure refrigerant from the evaporator is drawn into compressor 2, compressed into high-temperature, high-pressure refrigerant gas by compressor 2, and then discharged into the condenser. The condensation process is as follows: The high-temperature, high-pressure refrigerant gas exchanges heat with the external environment through the condenser, its temperature decreases, and it is gradually cooled into room-temperature, high-pressure refrigerant saturated vapor, and then further cooled into refrigerant saturated liquid. The throttling process is as follows: The condensed saturated refrigerant liquid is filtered through a dryer to remove moisture and impurities before flowing into the throttling device. The device reduces pressure, transforming the refrigerant into low-pressure, room-temperature wet vapor. The evaporation process: This low-pressure, room-temperature wet vapor enters the evaporator, absorbs heat, and vaporizes, lowering the temperature of the evaporator and its surroundings, thus achieving refrigeration. This process also transforms the refrigerant into a low-temperature, low-pressure gas. The refrigerant exiting the evaporator returns to compressor 2, repeating the above process. Through the change in the refrigerant's state, energy is converted, transferring heat from inside the refrigeration equipment 100 to the outside air, thereby completing the refrigeration cycle of the refrigeration equipment 100.

[0045] An air supply system is installed inside the cabinet 1 to provide power for the flow of cold air. The air supply system generally includes a fan (not shown in the figure) and an air supply duct defined within the cabinet 1. In some embodiments, the air inlet of the air supply duct is located close to the fan, and the air outlet is located away from the fan. In other embodiments, the air outlet is located close to the fan, and the air inlet is located away from the fan. An air duct cavity is also defined within the cabinet 1, which communicates with both the air supply duct and the cooling compartment inside the cabinet, allowing the air supply duct to connect with the cooling compartment via the air duct cavity. It should be noted that the cabinet has an air outlet (not shown in the figure) connecting the air duct cavity and the cooling compartment. The fan draws cold air generated by the refrigeration system through the air supply duct into the air duct cavity and then flows through the air outlet to the cooling compartment to cool it. It should also be noted that in some embodiments, the air outlet is located on the side wall opposite to the access port of the cabinet and the refrigeration compartment, or on the side wall adjacent to the access port of the cabinet and the refrigeration compartment; it should also be noted that the refrigeration system and the air supply system are common knowledge in the art, and will not be described in detail here.

[0046] See Figure 1-10 As shown, in this embodiment, the side of the refrigeration device 100 facing the user during use is considered the front side, and the opposite side is considered the rear side. The top and bottom sides of the refrigeration device 100 during normal operation are used to distinguish the upper and lower sides. The left and right sides of the user facing the refrigeration device 100 are used to distinguish the left and right sides. This refrigeration device 100 includes at least a cabinet 1, a compressor 2, a control component 3, and a connecting harness 4. The cabinet 1 has at least a first receiving cavity 11. The compressor 2 is located within the first receiving cavity 11 and has a first control box 21 for controlling its operation. The control component 3 is located within the first receiving cavity 11 and is used for frequency conversion control of the compressor 2. The control component 3 includes a second control box 31 and a control board 32. The second control box 31 is connected to the cabinet 1 and is located beside the compressor 2, opposite to the first control box 21. The control board 32 is detachably connected to the second control box 31. The control board 32 is equipped with a main control processing module 323, a display control module 324, a filtering module 32a, and a variable frequency drive processing module 326. The main control processing module 323 is connected to the variable frequency drive processing module 326 to perform variable frequency control on the compressor 2. The display control module 324 is connected to the main control processing module 323 to display the control information of the main control processing module 323. The filtering module 32a is connected to the power supply. One end of the connecting harness 4 is connected to the control board 32, and the other end of the connecting harness 4 is connected to the compressor 2, so that the control board 32 is connected to the first control box 21 through the connecting harness 4.

[0047] For the refrigeration device 100 of this embodiment, the control component 3 and the connecting harness 4 can be assembled before being installed in the first receiving cavity 11. After the control component 3, the connecting harness 4 and the compressor 2 are installed in the first receiving cavity 11, since the second control box 31 and the first control box 21 are arranged opposite each other, their outlets or the connecting ends used to connect to the connecting harness 4 are opposite, close to, or both close to each other, making the wiring work very simple. After the wiring is completed, the other end of the connecting harness 4 can be connected to the compressor 2. Compared with the technical solution that requires additional installation of filters and inverters in the receiving cavity and connection of filter and inverter related harnesses after installation, this refrigeration device 100 can greatly save space in the first receiving cavity 11 and simplify the assembly process of the components in the first receiving cavity. In summary, the assembly process of the components in the first receiving cavity 11 of the refrigeration device 100 of this embodiment is relatively short, resulting in high assembly efficiency and low cost.

[0048] It is understandable that in the existing refrigeration equipment 100 structure, the first receiving cavity 11 needs to accommodate the compressor 2, frequency converter, filter, and control components. To ensure smooth refrigerant flow, the compressor 2 is usually positioned in a preferred location within the first receiving cavity 11, while the frequency converter, filter, and control components are distributed in other locations. This often results in the frequency converter, filter, and control components being scattered around the compressor 2, leading to messy wiring harnesses connecting these components and hindering the assembly efficiency of the refrigeration equipment 100 structure. Therefore, the refrigeration equipment 100 of this embodiment integrates the main control processing module 323 and the display control module... Block 324, filter module 32a, and frequency conversion drive processing module 326 are integrated into control board 32, and the second control box 31 is positioned opposite to the first control box 21. In this way, not only can the connection and cooperation between main control processing module 323, display control module 324, filter module 32a, and frequency conversion drive processing module 326 be completed before the refrigeration equipment 100 is assembled, but the connection harness 4 between control board 32 and the first control box 21 can be restricted between the second control box 31 and the first control box 21, so that the connection harness 4 between compressor 2 and control board 32 can be uniformly planned and arranged, improving the space utilization of the first accommodating cavity 11.

[0049] In addition, for ease of wiring, the following configuration can be used: the second control box 31 can be disposed on the cavity wall of the first receiving cavity 11, and the first control box 21 can be disposed on the bottom surface of the first receiving cavity 11. The second control box 31 and the first control box 21 can be spaced apart in the front-back direction. The connecting wire harness exits from the side of the second control box 31 relative to the first control box 21. The first control box 21 has connecting ends for connecting the connecting wire harness 4 on the side of the second control box 31 or on both sides of the side, so that the wire through hole 317 of the second control box 31 and the connecting end are separated by a short distance. The connecting wire harness 4 can be connected to the connecting end from the wire through hole 317 without too many bends, making it easy for workers to assemble, greatly increasing assembly efficiency and reducing costs.

[0050] In addition, the connecting harness 4 can be a connecting wire such as a cable or wire with a conductive core inside and an insulating sleeve on the outside.

[0051] It should be noted that the refrigeration device 100 in this embodiment is a refrigerator or freezer, which is a device that can store items and refrigerate them to cool the stored items.

[0052] See Figure 10As shown in the example of this embodiment, the control board 32 may also be configured with a load acquisition and processing module 327, a button control processing module 328, a storage module 325, a power supply module 329, and a drive circuit 32b. The main control processing module 323 is connected to the display control module 324, the storage module 325, the load acquisition and processing module 327, the button control processing module 328, and the frequency conversion drive processing module 326. The frequency conversion drive processing module 326 is connected to the drive circuit 32b. The filter module 32a is integrated into the power supply module 329. The power supply module 329 is connected to the display control module 324, the storage module 325, the load acquisition and processing module 327, the button control processing module 328, the frequency conversion drive processing module 326, and the drive circuit 32b to supply power to the aforementioned modules and circuits.

[0053] It should be noted that this embodiment only limits and explains the types of modules provided on the control board 32 and how the modules are connected. Other aspects regarding how to achieve the original functions of the modules and circuits through modules and circuits are conventional technical means for those skilled in the art and will not be elaborated here.

[0054] See Figure 5-9 As shown in the example of this embodiment, the second control box 31 is provided with a second receiving cavity 311, and the control board 32 is arranged in the second receiving cavity 311 along the height direction; and the second receiving cavity 311 has a first end 3111 and a second end 3112 arranged opposite to each other in the height direction, the first end 3111 is above the second end 3112, the first end 3111 and the second end 3112 are respectively provided with a snap-fit ​​block 312, and the snap-fit ​​block 312 located at the first end 3111 is provided with a snap-fit ​​portion 313 extending toward the second end 3112, and the snap-fit ​​block 312 located at the second end 3112 is provided with a snap-fit ​​portion 313 extending toward the first end 3111, and the control board 32 is snapped into the snap-fit ​​block 312, and the side of the control board 32 facing the compressor 2 abuts against the snap-fit ​​portion 313.

[0055] In the above example, the snap-fit ​​block 312 and the snap-fit ​​part 313 allow the control board 32 to be detachably connected to the second control box 31, facilitating the disassembly and assembly of the control board 32 and the second control box 31 by the operator, thereby increasing the efficiency of disassembly and assembly. Specifically, the snap-fit ​​block 312 is connected to the top or bottom surface of the second receiving cavity 311 on the side facing up and down, and to the cavity wall of the second receiving cavity 311 on the side facing back and forth. The snap-fit ​​part 313 is connected to the side of the snap-fit ​​block 312 facing up and down, and there is a gap between the snap-fit ​​part 313 and the cavity wall of the second receiving cavity 311, within which the control board 32 is fixed. The specific installation process is that the operator can press the control board 32 into the second receiving cavity 311 or install it into the second receiving cavity 311 at an angle. The method within 1 allows the control board 32 to be detachably connected to the second control box 31; in addition, the refrigeration device 100 of this embodiment is not limited to the above-described example scheme. In some structures of the refrigeration device 100, only the snap-fit ​​block 312 located at the first end 3111 may be provided with a snap-fit ​​portion 313 extending toward the second end 3112, or only the snap-fit ​​block 312 located at the second end 3112 may be provided with a snap-fit ​​portion 313 extending toward the first end 3111. Although these two connection structures, in which the control board 32 is connected to the snap-fit ​​block 312 and the snap-fit ​​portion 313 on only one side, can make it more convenient for workers to assemble, the connection stability will be slightly reduced. This connection structure may need to be used in conjunction with other connection methods, or it may be used for positioning before implementing other connection methods.

[0056] See Figure 5 and 8 As shown in the example of this embodiment, the second receiving cavity 311 is provided with a connecting post 314. One end of the connecting post 314 is connected to the second receiving cavity 311, and the other end of the connecting post 314 abuts against the control plate 32. Furthermore, the connecting post 314 is provided with a first connecting hole 3141, and the control plate 32 is provided with a second connecting hole 321 that communicates with the first connecting hole 3141. Screws or other fasteners are passed through the second connecting hole 321 and inserted into the first connecting hole 3141.

[0057] In the above example, the fasteners connected to the first connecting block 31cc and the second connecting hole 321 make the control board 32 securely and detachably connected to the second control box 31. This prevents the control board 32 from easily loosening during the operation of the refrigeration equipment 100, while facilitating the disassembly and assembly of the control board 32 and the second control box 31 by the staff, thereby increasing the efficiency of disassembly and assembly.

[0058] In addition, when the second control box 31 has the connecting post 314, the snap-fit ​​part 313 and the snap-fit ​​block, the control board 32 is first initially fixed by the snap-fit ​​part 313 and the snap-fit ​​block, and then the control board is stably connected to the second control box 31 by the connecting post 314 and the connector. Also, the length of the connecting post 314 should be set to match the snap-fit ​​part 313 and the snap-fit ​​block 312 to avoid assembly failure.

[0059] See Figure 3-9 As shown in the example of this embodiment, the second control box 31 includes a box body 315 and a box cover 316. The box body 315 has an opening 3151 facing the compressor 2, and the box body 315 is provided with a plurality of snap-fit ​​protrusions 3152 respectively arranged on both sides of the opening 3151. The box cover 316 is provided with a snap-fit ​​hole 3161 that penetrates into its interior, and the box cover 316 covers the opening 3151, so that the snap-fit ​​protrusions 3152 are engaged with the snap-fit ​​hole 3161, thereby connecting the box body 315 to the box cover 316.

[0060] The connection between the latching protrusion 3152 and the latching hole 3161 facilitates the disassembly and assembly of the box body 315 and the box cover 316 by the operator, thereby increasing the disassembly and assembly efficiency of the second control box 31. In addition, the box body 315 and the box cover 316 form a through hole 317 for the connecting wire harness 4 to pass through. This allows the connecting wire harness 4 to detach from or enter the through hole 317 from the notch on one side of the through hole 317 when the operator is disassembling or assembling the box body 315 and the box cover 316, without having to slide a long distance with the through hole 317 to achieve the detachment or insertion operation. This not only facilitates the disassembly and assembly work and increases the efficiency of the disassembly and assembly work, but also reduces the wear of the connecting wire harness 4 and increases the service life of the connecting wire harness 4.

[0061] In addition, multiple snap-fit ​​protrusions 3152 and multiple snap-fit ​​holes 3161 are spaced apart along the height direction, and the snap-fit ​​protrusions 3152 and snap-fit ​​holes 3161 are correspondingly arranged. Specifically, the snap-fit ​​protrusions 3152 have chamfers or rounded corners on the side of the lid 316, and the lid 316 also has chamfers or rounded corners on the inner side of the snap-fit ​​protrusions 3152. When the lid 316 is closed on the opening 3151, the chamfers or rounded corners of the lid 316 and the chamfers or rounded corners of the inner side of the snap-fit ​​protrusions 3152 abut against each other to apply an outward force to the lid 316 and an inward force to the box body 315, opening the lid 316 and causing the box body 315 to retract inward, so that the snap-fit ​​protrusions 3152 can be smoothly inserted into the snap-fit ​​holes 3161 to achieve a detachable connection.

[0062] In addition, the box body 315 and the box cover 316 can form two rows of wire through holes 317. The two rows of wire through holes 317 are arranged horizontally on both sides. Each row of wire through holes 317 includes multiple wire through holes 317 arranged vertically. Specifically, one row of wire through holes 317 includes three wire through holes 317, and the other row of wire through holes 317 includes two wire through holes 317. The connecting wire harness 4 passes through one of the aforementioned wire through holes 317, and the remaining wire through holes 317 are respectively passed through by wire harnesses for connecting sensors, wire harnesses for connecting lamps, wire harnesses for connecting fans, and wire harnesses for connecting power supplies.

[0063] See Figure 3-9 As shown in the example of this embodiment, the box body 315 is provided with an outer edge portion 3153 on the same side as the buckle protrusion 3152, and the box cover 316 is recessed inward on one side of the buckle hole 3161 to form a clearance space 3162, and the clearance space 3162 has a clearance opening 3163 facing outward; and the box cover 316 covers the opening 3151, so that the outer edge portion 3153 is connected to the clearance opening 3163, and together with the clearance space 3162, forms the wire through hole 317. The wire through hole 317 extends through the box cover 316 along its own axis so that the connecting wire harness 4 is connected to the control board 32 through the wire through hole 317.

[0064] The clearance opening 3163 can block the through hole 317 to reduce dust from entering the second control box 31 through the through hole 317, thereby reducing the probability of the circuit board malfunctioning due to dust. Furthermore, a shielding protrusion can be provided around the clearance opening 3163 towards the first control box 21 to increase the degree of shielding of the through hole 317 and further enhance the dustproof effect.

[0065] See Figure 3-9 As shown, as an example of this embodiment, the control board 32 is provided with a heating area 322, which is close to the second end 3112 along the height direction. The second control box 31 is provided with a second receiving cavity 311, and the second control box 31 is provided with a plurality of heat dissipation holes 318 that penetrate into the second receiving cavity 311. The heat dissipation holes 318 are provided corresponding to the heating area 322.

[0066] The heat-generating area 322 refers to the area on the control board 32 where the modules, circuits, or other electronic components are densely arranged, resulting in high heat generation. Specifically, the heat-generating area 322 may house the main control processing module 323, the display control module 324, the storage module 325, the frequency conversion drive processing module 326, the load acquisition and processing module 327, the button control processing module 328, the power supply module 329, the filter module 32a, and the drive circuit 32b. In this embodiment, the heat-generating area 322 is located on the lower side of the control board 32, thus bringing the center of gravity of the control board 32 closer to its lower region, making the vertically mounted control board 32 more stable. The heat dissipation holes 318 are provided corresponding to the heat-generating area 322 to increase the heat dissipation efficiency of the area; in addition, the second control box 31 may be provided with multiple rows of heat dissipation holes 318 spaced apart along the height direction, and any row of heat dissipation holes 318 includes multiple heat dissipation holes 318 arranged in the horizontal direction; in addition, the diameter of the heat dissipation holes 318 should not be too large to prevent insects from passing through the heat dissipation holes 318 and entering the second receiving cavity 311.

[0067] See Figure 3-7 As shown in the example of this embodiment, the second control box 31 is provided with a plurality of external protrusions 319 spaced apart along the height direction. The plurality of external protrusions 319 protrude from the side of the compressor 2, and the external protrusions 319 have a first surface 3191 and a second surface 3192 arranged opposite to each other in the height direction. The first surface 3191 is above the second surface 3192, and the first surface 3191 is an inclined surface from its lower end to its upper end facing the first end 3111. The second surface 3192 is an inclined surface from its upper end to its lower end facing the second end 3112. The heat dissipation hole 318 is arranged on the second surface 3192. Furthermore, the cavity wall of the second receiving cavity 311 is provided with a clearance groove 3113 arranged corresponding to the external protrusions 319. The clearance groove 3113 extends outward toward the outside of the second control box 31 and communicates with the heat dissipation hole 318.

[0068] In the above example, after the condensate slides down the cavity wall of the second receiving cavity 311, it can slide down the clearance groove 3113 to the heat dissipation hole 318 and then be discharged outward, so as to reduce the amount of condensate accumulation in the second receiving cavity 311 and thus reduce the risk of failure caused by excessive condensate accumulation in the circuit board.

[0069] Specifically, the outer protrusion 319 can be provided on the side of the cover 316 relative to the first control box 21. The outer protrusion 319 can extend horizontally on both sides of the cover side. The heat dissipation hole 318 can penetrate from the clearance groove 3113 to the second surface 3192. Multiple heat dissipation holes 318 are arranged from one end of the outer protrusion 319 to the other end to obtain a better heat dissipation effect.

[0070] See Figure 1-3 As shown in Figure 9, as an example of this embodiment, the front side wall of the cabinet 1 is provided with a mounting hole that penetrates to the first receiving cavity 11; the second control box 31 is provided with a screen through hole 31a on the side away from the compressor 2, the screen through hole 31a penetrates to the interior of the second control box 31, and the second control box 31 is connected to the front side wall of the cabinet 1, so that the screen through hole 31a is located in the mounting hole; the control board 32 is connected to a display screen 31b, the display screen 31b is located on the side of the control board 32 away from the compressor 2, and extends through the screen through hole 31a into the mounting hole.

[0071] Users and staff can easily observe the display screen 31b inside the mounting hole from the front of the refrigeration equipment 100, which facilitates its use and maintenance. In addition, to improve the visual effect of the refrigeration equipment 100, the exposed side of the display screen 31b, the exposed side of the second control box 31, and the outer side of the refrigeration equipment 100 are coplanar.

[0072] See Figure 3-9 As shown in the example of this embodiment, the inner side of the mounting hole is provided with a connecting groove; and the side of the second control box 31 away from the compressor 2 is provided with an outer edge 31d of the panel extending outward, the outer edge 31d of the panel engaging in the connecting groove; and at least one side of the second control box 31 is provided with a connecting block 31cc, the connecting block 31cc extending outward from the second control box 31, and the end of the connecting block 31cc away from the second control box 31 abutting against the inner side of the mounting hole to press the mounting hole and fix the second control box 31.

[0073] When installing the second control box 31 into the cabinet 1, the operator can insert one side of the outer edge 31d of the panel diagonally into the connecting groove, and then press the other side of the outer edge 31d of the panel into the connecting groove so that the outer edge 31d of the panel is engaged with the connecting groove, so that the second control box 31 and the cabinet 1 are initially positioned and fixed. At this time, there is still a gap between the outer edge 31d of the panel and the connecting groove. Then, by pressing the connecting block 31c, the connecting block 31cc abuts against the mounting hole, so that the second control box 31 is firmly connected to the cabinet 1.

[0074] See Figure 3-5 As shown in Figures 8 and 9, as an example of this embodiment, the second control box 31 includes a first box portion 31e and a second box portion 31f. The first box portion 31e and the second box portion 31f are arranged sequentially from the direction away from the compressor 2 to the direction closer to the compressor 2, and the length of the second box portion 31f in the height direction is greater than the length of the first box portion 31e in the height direction. Furthermore, the second control box 31 is provided with a second receiving cavity 311, and the second receiving cavity 311 includes a first chamber 3114 and a second chamber 3115 that are connected. The first chamber 3114 is correspondingly disposed in the first box portion 31e, and the second chamber 3115 is correspondingly disposed in the second box portion 31f. Furthermore, the control board 32 is located in the second chamber 3115, and the display screen 31b extends through the first chamber 3114 and the screen through hole 31a into the mounting hole.

[0075] It should be noted that the existing refrigeration equipment 100 structure includes a control board and a control box for assembling the control board 32. Since the existing control board 32 generally only integrates the main control processing function, display control function, storage function, load acquisition and processing function, and key control processing function, but does not integrate the frequency conversion drive processing function and filtering function, the existing control board 32 is relatively small in size, and correspondingly, the size of the existing control box that accommodates it is also relatively small. The mounting holes on the cabinet 1 of the existing refrigeration equipment 100 structure are made according to the specifications and dimensions of the existing control box, resulting in a small shape and size of the mounting holes on the cabinet 1. In this embodiment, the second control box is divided into a first box part 31e and a second box part 31f. The first box part 31e and the first chamber 3114 are smaller. The first box part 31e is located inside the mounting hole and is used to fit the mounting hole for connection. The second box part 31f and the second chamber 3115 are larger. The control board 32 is located inside the second chamber 3115 to accommodate the control board 32. In this way, the second control box 31 of this embodiment can be directly adapted to the cabinet 1 of the existing refrigeration equipment 100 structure. That is, the solution provided by this embodiment can be directly applied to the existing refrigeration equipment 100 structure without the need to re-fabricate the cabinet 1 of the refrigeration equipment 100 structure. Additionally, a connecting post 314 may be provided on the cavity wall of the first chamber 3114, and a connector may be used to pass through the second connecting hole 321 and be inserted into the first connecting hole 3141 so that the first box part 31e is connected to the control board 32; in addition, the first box part 31e and the second box part 31f may be part of the box body 315.

[0076] In addition, when the width or height of the control board 32 in the horizontal direction is designed to be relatively high, the second box portion 31f can protrude from the side of the first box portion 31e in the corresponding direction to accommodate the corresponding control board 32.

[0077] In addition, since the connection between the multiple components in the second control box 31 needs to be achieved through a certain degree of elasticity and plasticity (such as the buckle protrusion 3152 and the buckle hole 3161), the second control box 31 can be made of a material with a certain degree of elasticity and plasticity, such as plastic.

[0078] In addition, the specific connection method of detachable connection refers to the fact that the two connected parts can be repeatedly disassembled and assembled without damage or serious deformation, including fixed connection by connectors and fixed connection by buckles.

[0079] In addition, the specific connection methods of fixed setting and fixed connection refer to the relative positional relationship of two connected components that can be fixed, including fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0080] In addition, connectors include, but are not limited to, fasteners, straps, ropes, pneumatic connectors, hydraulic connectors, flanges, Velcro, buttons, and pins.

[0081] In summary, this embodiment provides a refrigeration device 100, the technical effects of which are as follows:

[0082] In this embodiment of the refrigeration equipment 100, the compressor 2, controller, and connecting harness 4 are all located within the first receiving cavity 11. The control board 32 integrates a main control processing module 323, a display control module 324, a filter module 32a, and a frequency converter drive processing module 326, and is located within the second control box 31. One end of the connecting harness 4 is connected to the control board 32, allowing the controller and connecting harness 4 to be assembled before being installed in the first receiving cavity 11. After the controller, connecting harness 4, and compressor 2 are installed in the first receiving cavity 11, only wiring needs to be arranged, and the other end of the connecting harness 4 needs to be connected to the compressor 2. Compared to the technical solution that requires additional installation of filters and frequency converters within the receiving cavity, and the connection of related wiring harnesses after installation, this refrigeration equipment 100 significantly saves space within the first receiving cavity 11 and simplifies the assembly process of the components within the first receiving cavity. In summary, the assembly process of the components within the first receiving cavity 11 of the refrigeration equipment 100 in this embodiment is relatively simple, resulting in higher assembly efficiency and lower cost.

[0083] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
