[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] It should be noted that all directional indications in this embodiment are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0054] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0056] This application is described below with reference to the accompanying drawings and specific embodiments:

[0057] The electronic control component and refrigeration equipment provided in this embodiment aim to at least partially solve the technical problem that the circuit components of refrigeration equipment are often distributed, that is, each functional module is installed in different physical locations, which increases the difficulty of wiring.

[0058] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The electronic control component in this embodiment includes a panel 18 and a control circuit assembly 20. The control circuit assembly 20 is disposed on the panel 18 and integrates a main control circuit, a frequency adjustment circuit, and a display circuit. The display circuit has a display screen, and the panel 18 has a display hole 11, with the display screen facing the display hole 11.

[0059] The main control circuit can not only control the temperature of the refrigeration equipment, but also control the operation of the fan and the defrosting of the refrigeration equipment.

[0060] The frequency adjustment circuit includes a signal input port electrically connected to the main control circuit and a signal output port connected to the compressor.

[0061] The panel 18 can be part of the cabinet 100 of the refrigeration equipment, a separate panel, or part of the electrical control box 10.

[0062] Because the control circuit assembly 20 integrates the main control circuit, frequency adjustment circuit, and display circuit, it combines control, frequency adjustment, and display functions into one unit, thus reducing the number of independent components. The integrated design eliminates intermediate connectors (such as wire harnesses and connectors) used to connect various components, reducing assembly difficulty, the types and quantities of components, and costs. It also reduces connection steps and the number of interfaces, simplifying the assembly process, improving production efficiency, and shortening the production cycle. Furthermore, it reduces assembly errors caused by improper connections between multiple components, allowing the control circuit assembly 20 to be installed as a whole, reducing cumulative errors caused by assembling components one by one, and improving overall assembly accuracy. At the same time, the integrated design makes the control circuit assembly 20 more compact in its spatial layout, reducing the space occupied by multiple components that are scattered.

[0063] Since the display circuit has a display screen and the panel 18 has a display hole 11, with the display screen and the display hole 11 facing each other, the data displayed on the display screen can be directly exposed outside the panel 18 through the display hole 11 and clearly displayed outside the panel 18. Users or operators can intuitively understand the operating status of the equipment without opening the panel 18 or using other tools, which improves the convenience and safety of operation.

[0064] In some embodiments, the display circuit is electrically connected to the main control circuit. The main control circuit sends display signals to the display circuit to control the data displayed on the screen, so that the screen can display the operating status of the refrigeration equipment.

[0065] In some embodiments, in order to control the compressor of the refrigeration equipment, the frequency adjustment circuit includes at least one of a variable frequency adjustment circuit and a fixed frequency adjustment circuit.

[0066] When the frequency adjustment circuit is a variable frequency adjustment circuit, the variable frequency adjustment circuit can dynamically change the frequency of the signal as needed. By adjusting the power supply frequency of the compressor, more precise control and higher operating efficiency can be achieved.

[0067] When the frequency adjustment circuit is a fixed frequency adjustment circuit, the fixed frequency adjustment circuit can keep the frequency of the signal stable and the working state is relatively fixed. Therefore, its reliability is usually high, ensuring the stability and reliability of the compressor during long-term operation.

[0068] Combination Figure 4 , Figure 6 , Figure 7 and Figure 9 In some embodiments, to ensure the integration of the control circuit board 20, the control circuit assembly 20 includes a control board 21 and a display board 22 electrically connected to the control board 21 to realize signal transmission between the control board 21 and the display board 22. The control board 21 integrates a main control circuit and a frequency adjustment circuit, while the display board 22 integrates a display circuit.

[0069] The control board 21 integrates the control circuit and the frequency adjustment circuit. In other words, the control board 21 combines the control function and the frequency adjustment function into one, realizing the merging of functional units, thereby reducing the number of independent parts. The integrated design eliminates the intermediate connectors (such as wire harnesses, connectors, etc.) originally used to connect various components, reducing assembly difficulty, reducing the types and number of parts, reducing costs, and also reducing connection steps and the number of interfaces, simplifying the assembly process, improving production efficiency, and shortening the production cycle. Moreover, it can reduce assembly errors caused by improper connection between multiple parts, allowing the control board 21 to be installed as a whole, reducing the cumulative errors caused by assembling parts one by one, and improving the overall assembly accuracy. At the same time, the integrated design makes the control board 21 more compact in spatial layout, reducing the space occupied by multiple components scattered.

[0070] Combination Figure 5 and Figure 7 In some embodiments, in order to achieve temperature regulation of the refrigeration equipment, the display panel 22 has a temperature adjustment trigger, and the panel 18 is provided with an operating element 30 for triggering the temperature adjustment trigger.

[0071] When the operating element 30 is activated, the main control circuit can be triggered by the temperature adjustment trigger, so that the frequency adjustment circuit sends a frequency adjustment signal. It can be understood that the operating element 30 drives the temperature adjustment trigger to activate, so as to input the adjustment signal to the main control circuit. The main control circuit sends a control signal to the frequency adjustment circuit according to the adjustment signal. The frequency adjustment circuit is electrically connected to the compressor. The frequency adjustment circuit sends a frequency adjustment signal to the compressor of the refrigeration equipment according to the control signal, so as to control the operation of the compressor.

[0072] The operating element 30 is located at least partially outside the panel 18. When the temperature needs to be adjusted, the user can operate the operating element 30 directly outside the panel 18 so that the operating element 30 can drive the temperature adjustment trigger to move. In other words, the user can directly operate the temperature adjustment trigger through the operating element 30 without opening the electrical control box 10, thereby adjusting the temperature. This simplifies the operation steps, improves the user experience, and reduces the risk of the user directly contacting electrical components, thus improving safety.

[0073] In some embodiments, for ease of observation by the user, the display hole 11 is necessarily located on the outer side of the panel 18. For ease of operation by the user, the operating element 30 is located on the same side of the panel 18 as the display hole 11. That is, the operating element 30 is partially located on the outer side of the panel 18, so that the user can see the status of the display screen more intuitively through the display hole 11 and perform corresponding operations on the operating element 30 according to the prompts on the display screen. This reduces the time that the user needs to find and confirm the position of the display screen and improves the convenience and efficiency of operation.

[0074] Designing the display hole 11 and the operating element 30 on the same side can make more efficient use of the surface space of the panel 18. The compact layout helps to reduce the overall size of the panel 18. Moreover, it can enhance the design consistency of the panel 18, making the appearance of the control box neater and more orderly, and improving the overall aesthetics of the product.

[0075] Because the display panel 22 needs to have the display hole 11 located on the outside of the panel 18 for easy viewing, the operating component 30 should also be located on the outside of the panel 18 for easy operation.

[0076] Of course, in some other embodiments, the operating element 30 and the display hole 11 are located on different sides of the control box 10.

[0077] In some embodiments, the operating element 30 includes a temperature control adjustment button. Pressing the temperature control adjustment button actuates the temperature adjustment trigger, thereby inputting an adjustment signal to the main control circuit. Of course, in other embodiments, the operating element 30 may include a knob. Rotating the knob actuates the temperature adjustment trigger, thereby inputting an adjustment signal to the main control circuit.

[0078] Combination Figure 4 , Figure 7 and Figure 9 In some embodiments, to facilitate the arrangement of the control board 21 and the display board 22, the control board 21 and the display board 22 are set at an angle, which can effectively avoid direct overlap between the two in the horizontal or vertical direction, thereby maximizing the use of three-dimensional space. This allows the entire electronic control component to achieve more compact and efficient space utilization while maintaining functional integrity, which is conducive to the miniaturization and lightweight design of the product. Moreover, the control board 21 and the display board 22 will generate a certain amount of heat during operation. Arranging the control board 21 and the display board 22 at an angle can increase the air circulation path, which is conducive to heat dissipation and heat dissipation efficiency. This can ensure the stable operation of the electronic control component, extend its service life, and reduce failures caused by overheating.

[0079] In some embodiments, the included angle between the control panel 21 and the display panel 22 can be an acute angle, a right angle, or an obtuse angle. When the control panel 21 and the display panel 22 are perpendicular, the perpendicular relationship between the control panel 21 and the display panel 22 is not absolutely perpendicular in a geometric sense, and the angular relationship between the control panel 21 and the display panel 22 can be in the range of 90±3°.

[0080] In some embodiments, the control panel 21 may be arranged along the thickness direction of the panel 18, and the display panel 22 may be arranged along the width direction of the panel 18. Of course, in some other embodiments, the control panel 21 may be arranged parallel to the display panel 22.

[0081] In some embodiments, to further facilitate user operation, the display screen includes a touch control unit that allows users to operate the device by directly touching the screen. This intuitive operation reduces the learning curve and enables users to become familiar with and use the device more quickly.

[0082] In some embodiments, the control panel 21 is disposed inside the housing 14, and the display panel 22 is disposed inside the cover 15.

[0083] Combination Figure 5 In some embodiments, to display the operating status of the refrigeration equipment, the electronic control component further includes an indicator light 80. The panel 18 has a light-emitting hole 13 corresponding to the indicator light 80, and the light-emitting hole 13 and the display hole 11 are located on the same side of the panel 18. The indicator light 80 is integrated into the display circuit. The indicator light 80 is integrated into the display panel 22.

[0084] The light from the indicator light 80 can be directly exposed to the panel 18 through the light outlet 13, and clearly displayed outside the panel 18. Users or operators can intuitively understand the operating status of the equipment without opening the control box 10 or using other tools, which improves the convenience and safety of operation.

[0085] To facilitate user observation, the display hole 11 is necessarily located on the outside of the panel 18. To facilitate user operation, the light-emitting hole 13 and the display hole 11 are located on the same side of the panel 18. Users can see the status of the indicator light 80 more intuitively through the light-emitting hole 13, reducing the time users need to find and confirm the location of the indicator light 80, and improving the convenience and efficiency of operation.

[0086] The indicator light 80 is integrated into the display circuit, reducing the number of independent components. The integrated design eliminates the intermediate connectors (such as wire harnesses, connectors, etc.) that were originally used to connect the various components, reducing assembly difficulty, reducing the types and number of components, reducing costs, and also reducing connection steps and the number of interfaces, simplifying the assembly process, improving production efficiency, and shortening the production cycle. Moreover, it can reduce assembly errors caused by improper connection between multiple components, allowing the control circuit board 20 to be installed as a whole, reducing the cumulative errors caused by assembling components one by one, and improving the overall assembly accuracy. At the same time, the integrated design makes the display circuit more compact in spatial layout, reducing the space occupied by multiple components scattered.

[0087] Designing the display hole 11 and the light emission hole 13 on the same side can make more efficient use of the surface space of the panel 18. The compact layout helps to reduce the overall size of the panel 18. Moreover, it can enhance the design consistency of the panel 18, making the appearance of the control box neater and more orderly, and improving the overall aesthetics of the product.

[0088] Since the display panel 22 needs to have the display hole 11 located on the outside of the panel 18 for easy viewing, the light emission hole 13 should also be located on the outside of the panel 18 for easy operation.

[0089] Combination Figure 4 , Figure 10 and Figure 11 In some embodiments, the electronic control assembly further includes an electronic control box 10. To facilitate the installation of the control circuit assembly 20 within the box 10, the electronic control box 10 includes a box body 14 and a cover 15. The cover 15 is detachably connected to the box body 14. When the control circuit assembly 20 needs to be installed, the cover 15 is removed from the box body 14, allowing the control circuit assembly 20 to be installed inside the box body 14, improving installation efficiency. The cover 15 is then reconnected to the box body 14, sealing the box body 14 to prevent the control circuit assembly 20 from being exposed, thus ensuring the safety of the control circuit assembly 20.

[0090] The control circuit assembly 20 is housed inside the control box 10. Therefore, by housing the control circuit assembly 20 in the control box 10, the control circuit assembly 20 is prevented from being exposed to the outside, thus ensuring the safety of the control circuit assembly 20 and also ensuring aesthetics.

[0091] By housing the control circuit assembly 20 in a single control box 10, the control function, frequency adjustment function, and display function are integrated into one control box 10. This reduces the number of parts and wiring complexity, thereby simplifying the production process, reducing manufacturing costs, reducing labor intensity, and also reducing the failure rate caused by messy wiring, thus improving reliability and stability.

[0092] The housing 14 or the cover 15 includes a panel 18. It is understood that the panel 18, as part of the housing 14 or the cover 15, allows the display hole 11 to be directly formed on it without the need for additional openings. This improves the overall structural integration of the control box 10, making the overall structure more compact and stable. Furthermore, the display hole 11 can directly display the data on the display screen on the panel 18, allowing users to easily observe the data without opening the cover 15 or moving other parts, thus improving ease of observation. The panel 18 is the bottom wall of the housing 14 or the bottom wall of the cover 15; that is, the panel 18 is part of the housing 14 or the cover 15.

[0093] In some embodiments, when panel 18 is part of box body 14, panel 18 and box cover 15 are located on opposite sides of the body of box body 14. Of course, in other embodiments, when panel 18 is part of box cover 15, panel 18 and box body 14 are located on opposite sides of the body of box cover 15.

[0094] In some embodiments, since the cover 15 is usually the part of the control box 10 that is relatively easy to open and access, and the panel 18 serves as the interface for the user to interact with the control box 10, the cover 15 includes the panel 18, which facilitates user operation and observation.

[0095] The display circuit is installed on the cover 15 and is arranged adjacent to the panel 18, so that the display data (such as status indication, parameter settings, etc.) can be directly and clearly displayed to the user, while keeping the internal space of the control box 10 clean and effectively utilized.

[0096] The main control circuit and frequency adjustment circuit are installed in the housing 14, which effectively protects the main control circuit and frequency adjustment circuit and reduces the risk of failure caused by the external environment.

[0097] Combination Figure 11 In some embodiments, to facilitate the installation of the control circuit assembly 20, the control box 10 is provided with a fixing slot 12. The first circuit board containing the main control circuit and frequency adjustment circuit is embedded in the fixing slot 12. When installing the first circuit board, the installer only needs to align the first circuit board with the slot of the fixing slot 12 and push it in to fix the first circuit board. No additional fasteners such as screws and nuts are required, which shortens the installation time, reduces the installation difficulty, and improves work efficiency. Moreover, the fixing slot 12 provides precise positioning and guidance for the first circuit board, ensuring that the first circuit board can be accurately aligned with its proper position during installation. This can reduce the risk of performance degradation or failure due to installation position deviation, and improve stability and reliability. At the same time, when the first circuit board needs maintenance and replacement, it can simply be removed from the fixing slot 12 without damaging the surrounding structure or performing complex disassembly work, which can reduce maintenance costs and improve the maintainability of the equipment. The fixing slot 12 can be opened in the box body 14, and the first circuit board is the control board 21.

[0098] In some embodiments, in order to ensure the stability of the first circuit board installation, the width of the fixing groove 12 is matched with the thickness of the first circuit board, so that a tight connection structure is formed between the first circuit board and the fixing groove 12. This structure helps to disperse and absorb external vibrations and impacts, thereby protecting the first circuit board from damage and ensuring the safety of the first circuit board.

[0099] In some embodiments, the edge of the first circuit board is embedded in the fixing groove 12, which can reduce the area of ​​the first circuit board obstructed by the groove wall of the fixing groove 12, ensure the heat dissipation area between the first circuit board and the outside world, facilitate heat dissipation and improve heat dissipation efficiency, ensure the stable operation of the electronic control components, extend service life, and reduce failures caused by overheating.

[0100] Combination Figure 10 and Figure 11 In some embodiments, to ensure the stability of the first circuit board installation, the control box 10 is provided with a first support member 40, which abuts against the first circuit board. The first support member 40 and the fixing groove 12 are located on opposite sides of the first circuit board.

[0101] When the first circuit board is to be installed, it is embedded in the fixing groove 12 and abuts against the first circuit board by the first support member 40. The first support member 40 and the fixing groove 12 are located on opposite sides of the first circuit board. The first support member 40 and the fixing groove 12 cooperate to apply force from both sides of the first circuit board, forming a clamping effect. This clamping force effectively prevents the first circuit board from shaking or shifting, ensuring the stability and reliability of the installation of the first circuit board.

[0102] In some embodiments, the first support member 40 is spaced apart from the fixing groove 12. That is, the edge of one side of the first circuit board abuts against the first support member 40, and the edge of the side of the first circuit board opposite to the first support member 40 is embedded in the fixing groove 12. There is a gap between the first support member 40 and the fixing groove 12, which can reduce the area of ​​the fixing groove 12 wall and the first support member 40 that obstructs the first circuit board, ensuring the heat dissipation area between the first circuit board and the outside world. This is beneficial for heat dissipation and heat dissipation efficiency, ensuring the stable operation of the electronic control components, extending the service life, and reducing failures caused by overheating.

[0103] In some embodiments, the first support member 40 is mounted on the cover 15.

[0104] Combination Figure 10 and Figure 11 In some embodiments, to ensure the stability of the control circuit 20, the control box 10 is provided with a second support 50 and a clip 60, and the second circuit board where the display circuit is located abuts against the second support 50 and the clip 60. The second support 50 and the clip 60 are located on opposite sides of the second circuit board, which is the display board 22.

[0105] In some embodiments, when installing the second circuit board, the second circuit board abuts against the second support member 50 and the clip 60. The clip 60 and the second support member 50 are located on opposite sides of the second circuit board. The clip 60 and the second support member 50 cooperate with each other, and the clip 60 and the second support member 50 apply force from opposite sides of the second circuit board to form a clamping effect. This clamping force effectively prevents the second circuit board from shaking or displacing, ensuring the stability and reliability of the second circuit board installation.

[0106] In some embodiments, when installing the second circuit board, the installer only needs to place the second circuit board on the second support 50 and then press the clip 60 onto the second circuit board to fix the second circuit board. No additional fasteners such as screws and nuts are required, which shortens the installation time, reduces the installation difficulty, and improves work efficiency. At the same time, when the second circuit board needs maintenance and replacement, it can be simply removed from the control board fixing slot 101 without damaging the surrounding structure or performing complex disassembly work, which can reduce maintenance costs and improve the maintainability of the equipment.

[0107] Combination Figure 10 In some embodiments, the second support member 50 is provided with a mounting groove 51. When installing the second circuit board, the second circuit board can be placed in the mounting groove 51. The mounting groove 51 can provide precise positioning and guidance for the second circuit board, ensuring that the second circuit board can be accurately aligned with its proper position during installation. This can reduce the performance degradation or failure risk caused by installation position deviation and improve stability and reliability.

[0108] In some embodiments, the edge of the second circuit board abuts against the second support member 50 and the clip 60, which can reduce the area of ​​the second support member 50 and the clip 60 that obstructs the second circuit board, ensuring the heat dissipation area between the second circuit board and the outside world. This is beneficial for heat dissipation and improving heat dissipation efficiency, ensuring the stable operation of the electronic control components, extending their service life, and reducing failures caused by overheating.

[0109] In some embodiments, the second support 50 and the clip 60 are both mounted on the cover 15.

[0110] A display hole 11 is provided on the control box 10, allowing the user to observe the content displayed on the screen. However, the display hole 11 affects the sealing performance of the control box 10. In some embodiments, to ensure the sealing performance of the control box 10, a sealing element 70 is provided on the outside of the control box 10. The sealing element 70 and the display panel 22 are located on opposite sides of the control box 10. The sealing element 70 can be a transparent sticker.

[0111] Combination Figure 1 and Figure 4In some embodiments, the sealing element 70 and the display panel 22 are located on opposite sides of the control box 10. The sealing element 70 fits tightly with the control box 10, forming an effective sealing barrier that seals the through holes, ensuring isolation between the inside of the control box 10 and the external environment. This prevents external factors such as dust, moisture, and corrosive gases from entering the control box 10, effectively blocking external environmental damage. The electronic components inside the control box 10 can remain dry and clean, reducing malfunctions and damage caused by corrosion, oxidation, etc., protecting the safety and stability of the internal electronic components. Moreover, it avoids damage or affecting the sealing effect that might occur if the display panel 30 comes into direct contact with the sealing element 70, ensuring that the display panel 40 can display information normally without interference from the external environment. The sealing element 70 can be attached to the box cover 15.

[0112] Combination Figure 12 and Figure 15 In some embodiments, in order to facilitate the assembly of the control box 10 and to ensure aesthetics, the projection of the panel 18 toward the box body 14 is at least partially located in a portion of the box body 14 and / or the projected area of ​​the panel is smaller than the projected area of ​​the box body 14.

[0113] When the control box 10 is to be installed inside the housing 100 of the refrigeration equipment, the box 14 is inserted into the receiving cavity 1001 of the housing 100 through the opening 1002 on the housing 100, and the box 14 is assembled in the receiving cavity 1001. At this time, the panel 18 can close the opening 1002. Since the projection of panel 18 at least partially falls on a portion of the box 14 and / or the projected area of ​​panel 18 is smaller than the projected area of ​​box 14, the area of ​​opening 1002 matches the area of ​​panel 18 when panel 18 closes opening 1002. Furthermore, box 14 can be tilted into receiving cavity 1001 through opening 1002, ensuring convenient installation. That is, the area of ​​opening 1002 does not need to be greater than or equal to the area of ​​box 14; in other words, the area of ​​opening 1002 can be smaller than the area of ​​box 14, as long as panel 18 can close opening 1002. Simultaneously, box 14 has sufficient space to accommodate control circuit components 20. It is understandable that, while ensuring the electrical control box 10 can be smoothly installed into receiving cavity 1001, opening 1002 can be made smaller and more concealed, improving the overall aesthetic appearance of the refrigeration equipment's casing 100 and making the casing 100 look cleaner and more upscale.

[0114] Although the opening 1002 has a small area, the tilted insertion method allows the box 14 to still smoothly enter the receiving cavity 1001, which ensures both the convenience of installation and the aesthetics and space utilization.

[0115] In some embodiments, panel 18 constitutes the main body of lid 15. Panel 18 extends toward box body 14 to form part of lid 15. One edge of lid 15 extends outward and beyond the edge of panel 18 to form the whole of lid 15. Lid 15 and box body 14 correspond and cooperate. Therefore, along the direction of panel 18 toward box body 14, the projected area of ​​panel 18 is smaller than the projected area of ​​box body 14.

[0116] Of course, in other embodiments, the control box 10 can be installed inside the housing 100 at the opening 1002, which also allows the panel 18 to close the opening 1002.

[0117] Combination Figure 3 , Figure 10 and Figure 11 In some embodiments, to facilitate the assembly and disassembly of the box body 14 and the box cover 15, one of the box body 14 and the box cover 15 is provided with a first buckle 16, and the other is provided with a slot 17, with the first buckle 16 being engaged in the slot 17.

[0118] When installing the lid 15 onto the box body 14, the first snap-fit ​​16 engages with the slot 17, allowing the lid 15 to be quickly and accurately installed onto the box body 14. This also facilitates disassembly, eliminating the need for additional tools or complex steps, thus improving efficiency and reducing operational difficulty. It prevents the lid 15 from loosening or falling off the box body 14 in case of accidents, ensuring the stability of the lid 15 installation. Furthermore, the tight fit between the first snap-fit ​​16 and the slot 17 effectively improves the seal between the lid 15 and the box body 14, protecting them from external environmental influences. This also reduces the number of screws or rivets used, lowering costs. When removing the lid 15 from the box body 14, the first snap-fit ​​16 separates from the slot 17, achieving separation and improving disassembly efficiency.

[0119] In some embodiments, the box body 14 may be provided with a first buckle 16, and the box lid 15 may have a slot 17. Of course, in other embodiments, the box lid 15 may be provided with a first buckle 16, and the box body 14 may have a slot 17.

[0120] Combination Figure 8 and Figure 11In some embodiments, a wiring groove 111 is provided inside the housing 14 to supply power to the control circuit assembly 20. The electrical control assembly also includes a power cable 90. The power cable 90 passes through the wiring groove 111 and is electrically connected to the control circuit assembly 20. The wiring groove 111 constrains the power cable 90, allowing it to run in a specific direction. Simultaneously, it neatly fixes the power cable 90 within the groove, preventing tangled wiring. The power cable 90 is electrically connected to the main control circuit.

[0121] The wiring trough 111 is located on opposite sides of the main control circuit and the frequency adjustment circuit, respectively. This allows the power line 90 to be kept away from the main control circuit and the frequency adjustment circuit, thereby reducing the electromagnetic interference of the high voltage of the power line 90 on the main control circuit and the frequency adjustment circuit, and ensuring the normal operation of the main control circuit and the frequency adjustment circuit.

[0122] Based on the same inventive concept, this application also proposes a refrigeration device that uses the aforementioned electronic control component. The specific structure of the electronic control component is as described in the above embodiments. Since the electronic control component adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0123] Combination Figure 12 and Figure 15 In some embodiments, the refrigeration device includes a housing 100, which has a receiving cavity 1001 and an opening 1002 communicating with the receiving cavity 1001. An electrical control box 10 of the electrical control assembly is installed inside the receiving cavity 1001 through the opening. The display hole 11 of the electrical control box 10 and the opening 1002 are located on the same side of the housing 100. The main control circuit can also be used to collect the temperature of the refrigeration device.

[0124] The electrical control box 10 can be tilted and inserted into the receiving cavity 1001 through the opening 1002, so that the electrical control box 10 can smoothly enter the receiving cavity 1001, ensuring the convenience of installation and realizing the installation of the electrical control box 10.

[0125] Since the opening 1002 and the display hole 11 are located on the same side of the enclosure 100, the control box 10 can not only enter the receiving cavity 1001 through the opening 1002, but the user can also directly observe the display data on the screen through the opening 1002. This achieves dual use for the opening 1002, avoiding the need for multiple unnecessary openings on the enclosure 100, thus maintaining the streamlined appearance and cleanliness of the enclosure 100. The display hole 11 is located on the cover 15 of the control box 10.

[0126] Combination Figure 10In some embodiments, in order to ensure that the panel 18 completely closes the opening 1002, the edge of the panel 18 has an extension edge 181, which abuts against the inner wall of the opening 1002, thereby effectively preventing external substances (such as dust, moisture, etc.) from entering the interior of the box 100 through the opening 1002, ensuring the cleanliness and dryness of the interior of the box.

[0127] Combination Figure 16 In some embodiments, the housing 90 has a recess 1003 communicating with the opening 1002. The recess 1003 is located outside the receiving cavity 1001. When the electrical control box 10 is installed in the housing 90, the extension edge 181 of the panel 18 is embedded in the recess 1003. When the second buckle 19 abuts against the cavity wall of the receiving cavity 1001 and the extension edge 181 of the panel 18 abuts against the bottom of the recess 1003, the electrical control box 10 is limited along the installation direction of the electrical control box 10, thus ensuring the stability of the installation of the electrical control box 10.

[0128] Combination Figure 12 In some embodiments, to facilitate operation of the operating component 30, the panel 18 of the control box 10 and the opening 1002 are located on the same side of the housing 100. The operating component 30 passes through the panel 18 and is connected to the temperature adjustment trigger. The user does not need to move the position between the control box 10 and the housing 100 or change the operating direction. The user can directly operate the operating component 30 on the panel 18 through the opening 1002 so that the operating component 30 can drive the temperature adjustment trigger to move. This reduces the complexity and inconvenience of the operation process and improves the user experience.

[0129] Combination Figure 13 and Figure 14 In some embodiments, in order to ensure the stability of the electrical control box 10 during installation, the electrical control box 10 is provided with a second latch 19. The second latch 19 abuts against the cavity wall of the receiving cavity 1001. The abutment between the second latch 19 and the cavity wall provides an additional fixing point for the electrical control box 10, thereby significantly enhancing its installation firmness in the receiving cavity 1001 and reducing the risk of the electrical control box falling off or loosening due to external factors such as vibration and impact.

[0130] The second clip 19 is usually designed with an easy-to-operate structure, such as a flexible clip, which makes the installation process of the electrical control box 10 simpler and faster, without the need for additional fixing tools or materials, thus reducing installation costs and time.

[0131] Combination Figure 13 and Figure 14In some embodiments, to ensure the stability of the electrical control box 10 during installation, the electrical control box 10 is provided with a limiting member 110. The limiting member 110 abuts against the inner wall of the opening 1002. The abutment between the limiting member 110 and the inner wall of the opening 1002 provides a precise positioning point for the electrical control box 10, ensuring the accurate position of the electrical control box 10 after installation. At the same time, this abutment also plays a fixing role, preventing the electrical control box from shifting or shaking within the receiving cavity 1001, thereby ensuring the stability and reliability of the equipment.

[0132] In some embodiments, the limiting member 110 is set at an angle to the second buckle 19. Through the cooperation of the limiting member 110 and the second buckle 19, the control box 10 can be limited from two different directions. Therefore, it can more effectively prevent the control box 10 from shifting or shaking during installation or use, and improve the stability and reliability of the control box 10.

[0133] In some embodiments, the included angle between the limiting member 110 and the second buckle 19 can be set from 45° to 135°. In this embodiment, the included angle between the limiting member 110 and the second buckle 19 is 90°, that is, the limiting member 110 and the second buckle 19 are set perpendicularly. This is only an example and should not be construed as a limitation of this application.

[0134] In some embodiments, in order to facilitate the installation of the control box 10 into the receiving cavity 1001, the end of the limiting member 110 away from the control box 10 has a slope. After the box body 10 is inserted into the receiving cavity 1001 at an angle through the opening 1002, it is necessary to push the control box 10 into the receiving cavity 1001 so that the control box 10 is fully inserted into the receiving cavity 1001. At this time, the slope can be transitioned so that the control box 10 is fully inserted into the receiving cavity 1001.
