Description

Technical Field

[0001] This application belongs to the field of electrical technology, specifically relating to an electronic control component and a refrigeration device. Background Technology

[0002] In the field of refrigeration technology, refrigeration equipment such as refrigerators and freezers have become an indispensable part of people's daily lives. These devices achieve precise temperature control within a space through complex internal systems to meet various needs such as food preservation, pharmaceutical storage, and industrial cooling.

[0003] Electrical control components are installed on the enclosure of refrigeration equipment to control its operation. Wiring is required for signal transmission and power supply to these components. However, in existing technologies, cables are difficult to manage, affecting the normal operation of the control components. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an electronic control component and a refrigeration device, aiming to at least partially solve the technical problem that cables are difficult to store, affecting the normal use of the electronic control component.

[0005] The technical solution of this utility model is as follows:

[0006] An electronic control component is characterized in that it includes: an electronic control box, comprising a box body and a box cover detachably connected to the box body, wherein one of the box body and the box cover has a wire passage groove and the other has a wire clamping block, the wire clamping block cooperating with the wire passage groove to limit the cable; a control circuit board disposed inside the electronic control box; and the cable passing through the wire passage groove and electrically connected to the control circuit board.

[0007] In some implementations, the housing and the cover are respectively provided with locking parts, and the electronic control assembly further includes a locking member that cooperates with the locking parts. The locking parts and the wire passage are located on the same side of the housing or the cover.

[0008] In some implementations, one of the box body and the box lid is provided with a first buckle, and the other is provided with a slot, wherein the first buckle can be engaged in the slot.

[0009] In some embodiments, a reinforcing plate is provided on the inner side of the first side of one of the box body and the box cover at a distance, and both the first side and the reinforcing plate are provided with wire grooves. The second side of the other box body and the box cover is the pressure block, and the second side is engaged between the reinforcing plate and the first side.

[0010] In some implementations, the wire clamping block has a slot corresponding to the wire guide groove for accommodating the cable.

[0011] In some embodiments, the cable includes a power line and at least one signal line, and the cable tray includes a first cable tray and at least one second cable tray spaced apart; wherein the power line passes through the first cable tray and is electrically connected to the control circuit board, and the signal line passes through the second cable tray and is electrically connected to the control circuit board.

[0012] In some implementations, the control circuit board has a notch, and the power line includes a first segment and a second segment connected to the first segment. The first segment passes through the first wire channel and is located inside the electrical control box. One end of the second segment passes through the notch and is connected to the first segment, and the other end is electrically connected to the control circuit board. The first segment and the second segment are located on opposite sides of the control circuit board.

[0013] In some implementations, the control circuit board is disposed inside the electrical control box, and the first line segment is located between the box cover and the control circuit board.

[0014] In some implementations, the notch and the first wire routing groove are respectively disposed at opposite ends of the control circuit board for wiring. The housing has a first side plate and a second side plate disposed opposite to each other. Along the notch toward the first wire routing groove, the first side plate and the second side plate extend along the notch toward the first wire routing groove. The notch is closer to the second side plate than the first side plate, and the height of the second side plate is greater than the height of the first side plate.

[0015] In some implementations, the electrical control box is provided with a wiring channel, through which the power cable passes and is electrically connected to the control circuit board.

[0016] Based on the same inventive concept, this utility model also provides a refrigeration device, including a housing and the aforementioned electrical control component. The housing has a receiving cavity and an opening communicating with the receiving cavity. The electrical control box of the electrical control component passes through the opening and is installed in the receiving cavity. The cable tray and the cable are both located in the receiving cavity.

[0017] The beneficial effects of this utility model include at least the following:

[0018] Since the control circuit board is located inside the electrical control box, the control circuit board is housed in the electrical control box to prevent it from being exposed to the outside, thus ensuring the safety of the control circuit board.

[0019] Since the electrical control box includes a box body and a cover that is detachably connected to the box body, when installing the control circuit board, the cover can be removed from the box body to install the control circuit board inside the box, which improves installation efficiency. Then, the cover is connected to the box body to close the box body, thus preventing the control circuit board from being exposed and ensuring its safety.

[0020] Because one of the box body and the box cover has a cable passage groove, and the other has a cable clamping block, the cable clamping block works with the cable passage groove to limit the cable. The cable passes through the cable passage groove and connects to the control circuit board. Therefore, by passing the cable through the cable passage groove and connecting it to the control circuit board, and then connecting the box cover to the box body, the cable can be neatly entered into the electrical control box according to a predetermined path and sequence through the guidance of the cable passage groove, which facilitates cable routing and storage. Moreover, the cable clamping block works with the cable passage groove to limit the cable. The cable clamping block can press the cable tightly in the cable passage groove. By cooperating with the groove wall, the cable can be firmly fixed in the cable passage groove. When the cable is pulled or tugged outside the box, the cable inside the box will not be pulled or tugged, effectively preventing the cable from moving, shaking or falling off inside the box. This ensures the stability of the electrical connection between the cable and the control circuit board, guarantees the continuity and reliability of the cable signal transmission, and also ensures the stability of the power supply.

[0049] 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.

[0050] This application is described below with reference to the accompanying drawings and specific embodiments:

[0051] The electronic control component and cooling device provided in this embodiment aim to solve, to some extent, the technical problem that cables are difficult to store, affecting the normal use of the electronic control component.

[0052] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 13 The electrical control assembly in this embodiment includes an electrical control box 10, a control circuit board 20, and a cable 30. The electrical control box 10 includes a box body 12 and a cover 13 detachably connected to the box body 12. One of the box body 12 and the cover 13 has a cable passage groove 11, and the other has a cable clamping block 14. The cable clamping block 14 cooperates with the cable passage groove 11 to limit the cable 30. The control circuit board 20 is disposed inside the electrical control box 10. The cable 30 passes through the cable passage groove 11 and is electrically connected to the control circuit board 20.

[0053] Since the control circuit board 20 is located inside the control box 10, the control circuit board 20 is contained within the control box 10, thus preventing the control circuit board 20 from being exposed to the outside and ensuring the safety of the control circuit board 20.

[0054] Since the control box 10 includes a box body 12 and a cover 13 that is detachably connected to the box body 12, when the control circuit board 20 is to be installed, the cover 13 can be removed from the box body 12, and the control circuit board 20 can be installed inside the box body 12, which improves the installation efficiency. Then, the cover 13 is connected to the box body 12, and the box body 12 is closed by the cover 13 to ensure that the control circuit board 20 is not exposed, thus ensuring the safety of the control circuit board 20.

[0055] Since one of the housing 12 and the cover 13 has a wire-passing groove 11 and the other has a wire-pressing block 14, the wire-pressing block 14 cooperates with the wire-passing groove 11 to limit the cable 30. The cable 30 passes through the wire-passing groove 11 and is electrically connected to the control circuit board 20. Therefore, by passing the cable 30 through the wire-passing groove 11 and connecting it to the control circuit board 20, and then connecting the cover 13 to the housing 12, the cable 30 can be neatly entered into the electrical control box 10 according to a predetermined path and sequence through the guidance of the wire-passing groove 11. This facilitates the routing and storage of the cable 30. Moreover, the wire-pressing block 14 cooperates with the wire-passing groove 11. The clamping block 14 is used to limit the cable 30. It can clamp the cable 30 into the cable groove 11. By cooperating with the groove wall of the cable groove 11, the clamping block 14 can firmly fix the cable 30 in the cable groove 11. When the cable 30 is pulled or tugged outside the box 12, the cable 30 inside the box 12 will not be pulled or tugged. This effectively prevents the cable 30 from moving, shaking or falling off inside the box 12, ensuring the stability of the electrical connection between the cable 30 and the control circuit board 20. It can also ensure the continuity and reliability of the signal transmission of the cable 30, as well as the stability of the power supply.

[0056] By guiding the cable 30 through the cable tray 11, the cable 30 can be connected to the control circuit board 20 outside the control box 10 before the control circuit board 20 and the cable 30 are placed inside the control box 10. Compared to connecting the cable 30 to the control circuit board 20 inside the box 10, there is enough space outside the box 10 to connect the cable 30 to the control circuit board 20, which facilitates operation and improves work efficiency.

[0057] In some embodiments, the housing 12 may have a wire groove 11, and the housing cover 13 may have a wire pressing block 14. Of course, in other embodiments, the housing cover 13 may have a wire groove 11, and the housing 12 may have a wire pressing block 14.

[0058] In some embodiments, when the pressure block 14 is disposed on the housing 12, the housing 12 can be integrally formed with the pressure block 14, so that there is no seam or additional connecting parts (such as screws) between the housing 12 and the pressure block 14. This can reduce the risk of failure due to loosening or falling off, and also improve the stability of the connection between the housing 12 and the pressure block 14. At the same time, the absence of fasteners such as screws can simplify the manufacturing process, reduce the number of parts and assembly steps, improve production efficiency, and reduce material and labor costs.

[0059] In some embodiments, the cable and the cable tray 11 can be interference-fitted. After the cable 30 is pushed into the cable tray 11, it will be subjected to a certain squeezing force. This squeezing force can ensure that the cable 30 maintains a stable position in the cable tray 11 and is not easy to loosen or fall off, which can reduce connection failure or malfunction caused by the cable 30 loosening.

[0060] Combination Figure 3 and Figure 10 In some embodiments, to ensure the stability of the connection between the box body 12 and the box cover 13, the box body 12 and the box cover 13 are respectively provided with locking parts 15. The electronic control assembly also includes a locking member that cooperates with the locking part 15. The locking part 15 and the wire groove 11 are located on the same side of the box body 12 or the box cover 13. The locking member can be a bolt, screw or pin.

[0061] In some embodiments, the locking member is connected to the locking part 15, which allows the housing 12 to be connected to the cover 13, ensuring the stability of the connection between the housing 12 and the cover 13. Since the locking part 15 and the cable guide 11 are located on the same side of the housing 12 or the cover 13, when the cable clamping block 14 is pressed into the cable guide 11, the force of the locking member and the locking part 15 can be directly applied to the cable clamping block 14, providing additional clamping force to the cable clamping block 14. This clamping force ensures that the cable is firmly fixed in the cable guide 11, reducing the possibility of the cable loosening or falling off, and ensuring the stability and reliability of the cable connection. When the cable needs to be repaired, the cable can be released by adjusting the locking member. The operator does not need to enter the housing 10 or perform complex operations, which improves work efficiency and reduces the difficulty of operation and error rate.

[0062] In some embodiments, the locking part 15 may be provided on the box body 12 or the box cover 13. When the locking part 15 is provided on the box body 12, the locking member passes through the box cover 13 and is connected to the locking part 15. When the locking part 15 is provided on the box cover 13, the locking member 106 passes through the box body 12 and is connected to the locking part 15.

[0063] Combination Figure 3 , Figure 4 , Figure 10 and Figure 11 In some embodiments, in order to facilitate the assembly and disassembly of the box body 12 and the box cover 13, one of the box body 12 and the box cover 13 is provided with a first buckle 16, and the other is provided with a slot 17, and the first buckle 16 can be snapped into the slot 17.

[0064] When installing the lid 13 onto the box body 12, the first snap-fit ​​16 engages with the slot 17, allowing the lid 13 to be quickly and accurately installed onto the box body 12. This also facilitates disassembly, eliminating the need for additional tools or complex steps, thus improving efficiency and reducing operational difficulty. It prevents the lid 13 from loosening or falling off the box body 12 in case of accidents, ensuring the stability of the lid 13 installation. Furthermore, the tight fit between the first snap-fit ​​16 and the slot 17 effectively improves the seal between the lid 13 and the box body 12, protecting them from external environmental influences. This also reduces the number of screws or rivets used, lowering costs. When removing the lid 13 from the box body 12, the first snap-fit ​​16 separates from the slot 17, achieving separation and improving disassembly efficiency.

[0065] In some embodiments, the box body 12 may be provided with a first buckle 16, and the box lid 13 may be provided with a slot 17. Of course, in some other embodiments, the box lid 13 may be provided with a first buckle 16, and the box body 12 may be provided with a slot 17.

[0066] Combination Figure 3 and Figure 11 In some embodiments, in order to press the cable 30 into the cable groove 11 by the wire pressing block 14, a reinforcing plate 120 is provided on the inner side of the first side of one of the housing 12 and the cover 13 at intervals. Both the first side and the reinforcing plate 120 are provided with cable grooves 11. The second side of the other housing 12 and the cover 13 is the wire pressing block 14, which is engaged between the reinforcing plate 120 and the first side.

[0067] When the cover 13 is connected to the box body 12, the second side is engaged between the reinforcing plate 120 and the first side. That is, the wire clamping block 14 is engaged between the reinforcing plate 120 and the first side to clamp the cable 30 into the wire groove 11 and firmly fix the cable 30 in the wire groove 11. When the cable 30 is pulled or tugged outside the box body 12, the cable 30 inside the box body 12 will not be pulled or tugged, effectively preventing the cable 30 from moving, shaking or falling off inside the box body 12. This ensures the stability of the electrical connection between the cable 30 and the control circuit board 20, guarantees the continuity and reliability of the signal transmission of the cable 30, and also ensures the stability of the power supply.

[0068] A reinforcing plate 120 is provided on the inner side of the first side of one of the box body 12 and the box cover 13 at intervals. This can ensure the structural strength of the box body 12 and the box cover 13 and enhance the overall stability of the electrical control box 10. This makes one of the box body 12 and the box cover 13 more stable during transportation, storage and use, and less prone to deformation or damage.

[0069] The wire clamping block 14 is secured between the reinforcing plate 120 and the first side plate. The reinforcing plate 120 and the first side plate limit the position of the wire clamping block 14, achieving precise control and restriction of its position. This prevents the wire clamping block 14 from loosening or shifting during transportation or storage, thus ensuring the stability of the clamped cable 30. Furthermore, the clamping method simplifies and speeds up the installation of the wire clamping block 14, reducing manufacturing and assembly costs and improving production efficiency.

[0070] Combination Figure 4 In some embodiments, to accommodate and secure the cable 30, the wire clamping block 14 has a slot 141 corresponding to the cable guide 11. The slot 141 provides a dedicated channel for the cable 30, ensuring that the cable 30 remains orderly as it passes through the electrical control box 10 and reducing friction and interference with other components. Simultaneously, it makes the cable 30 arrangement more orderly and neat, reducing cable clutter and crossing, and improving cable management efficiency. The slot 141 can be arc-shaped to fit the cable 30.

[0071] Combination Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 12 and Figure 13 In some embodiments, to facilitate the arrangement of the cable 30, the cable 30 includes a power line 31 and at least one signal line 32, and the cable tray 11 includes a first cable tray 111 and at least one second cable tray 112 spaced apart. The power line 31 passes through the first cable tray 111 and is electrically connected to the control circuit board 20, and the signal line 32 passes through the second cable tray 112 and is electrically connected to the control circuit board 20.

[0072] When signal transmission between the control circuit board 20 and external devices is required, the signal line 32 passes through the second wire guide 112 and is electrically connected to the control circuit board 20. When power is supplied to the control circuit board 20, the power line 31 passes through the first wire guide 111 and is electrically connected to the control circuit board 20.

[0073] Because the first cable tray 111 and the second cable tray 112 are spaced apart, the power cable 31 passes through the first cable tray 111 and the signal cable 32 passes through the second cable tray 112. This spaced arrangement of the power cable 31 and the signal cable 32 ensures that each has its own dedicated channel, allowing for an orderly cable layout. When one of the power cable 31 or the signal cable 32 needs maintenance, there is no need to move or rearrange the other. Operations can be performed directly on either the first cable tray 111 or the second cable tray 112 where the power cable 31 or the signal cable 32 is located. This allows for quick and accurate identification of the location of the power cable 31 and the signal cable 32, improving maintenance efficiency and facilitating subsequent maintenance, upgrades, and troubleshooting. Furthermore, the orderly cable layout helps reduce the risk of misoperation during maintenance, improving work safety.

[0074] The power cable 31 is located in the first cable tray 111, and the signal cable 32 is located in the second cable tray 112. That is, the power cable 31 and the signal cable 32 are each fixed separately in their respective cable trays, which reduces the crossing, tangling and interference between the power cable 31 and the signal cable 32, reduces the risk of failure caused by the disorder of the power cable 31 and the signal cable 32, reduces the interference and signal attenuation between the power cable 31 and the signal cable 32, and improves the overall system performance.

[0075] Combination Figure 5 and Figure 6 In some embodiments, to supply power to the control circuit board 20, the control circuit board 20 has a notch 21. The power line 31 includes a first segment 311 and a second segment 312 connected to the first segment 311. The first segment 311 passes through the first wire channel 111 and is located inside the electrical control box 10. One end of the second segment 312 passes through the notch 21 and connects to the first segment 311, and the other end is electrically connected to the control circuit board 20. The first segment 311 and the second segment 312 are located on opposite sides of the control circuit board 20.

[0076] The first segment 311 can be connected to an external power source. The power from the external power source can be supplied to the control circuit board 20 in sequence through the first segment 311 and the second segment 312 to ensure that the circuit board 20 can work normally.

[0077] Because the control circuit board 20 has a notch 21, and the second line segment 312 passes through the notch 21 and connects with the first line segment 311, the notch 21 constrains the second line segment 312 and the first line segment 311, so that the first line segment 311 and the second line segment 312 can be routed in a specific direction. At the same time, the second line segment 312 and the first line segment 311 can be neatly fixed therein, avoiding messy wiring. There is no need to set a wiring trough in the electrical control box 10, which reduces costs.

[0078] Because the power cord 31 is flexible, when the second segment 312 passes through the notch 21 and connects with the first segment 311, it will bend at the notch 21. Under the action of tension, the first segment 311 and the second segment 312 will extend away from the control circuit board 20, so that there is a gap between the second segment 312 and the control circuit board 20 except at the connection point with the control circuit board 20 and the first segment 311. This can reduce the electromagnetic interference of the strong current of the second segment 312 and the first segment 311 on the control circuit board 20, and ensure the normal operation of the control circuit board 20.

[0079] In some embodiments, in order for the first line segment 311 and the second line segment 312 to be located on opposite sides of the control circuit board 20, the control circuit board 20 is disposed inside the housing 12 of the control box 10, the second line segment 312 is located between the housing 12 of the control box 10 and the control circuit board 20, and the first line segment 311 is located between the cover 13 and the control circuit board 20.

[0080] In some embodiments, in order to provide a clear routing path for the power line 31, the notch 21 and the first wire passage 111 are respectively provided at opposite ends of the control circuit board 20 for routing. When the first line segment 311 is electrically connected to the external power supply, it can run along the notch 21 towards the wire passage 11 until the first line segment 311 passes through the first wire passage 111, thus achieving an orderly layout of the power line 31.

[0081] Because the power cord 31 is inherently flexible, when the second segment 312 passes through the notch 21 and connects with the first segment 311, it will bend at the notch 21. Under tension, the first segment 311 will extend away from the control circuit board 20. Figure 7 In some embodiments, in order to ensure that the first line segment 311 can be sufficiently far away from the control circuit board 20, since the housing 12 has a first side plate 121 and a second side plate 122 arranged opposite to each other, the first side plate 121 and the second side plate 122 extend along the notch 21 towards the wire groove 11. The notch 21 is closer to the second side plate 122 than the first side plate 121. The height of the second side plate 122 is greater than the height of the first side plate 121, which can provide enough space for the first line segment 311 so that the first line segment 311 can be sufficiently far away from the control circuit board 20. This increases the distance between the first line segment 311 and the control circuit board 20, reduces the electromagnetic interference between the first line segment 311 and the control circuit board 20, and ensures the stability of the operation of the control circuit board 20.

[0082] In some embodiments, the control circuit board 20 integrates a main control circuit and a frequency adjustment circuit. Therefore, the control circuit board 20 integrates the control function and the frequency adjustment function into one unit, 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 quantities 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 circuit board 20 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 circuit board 20 more compact in spatial layout, reducing the space occupied by multiple parts scattered.

[0083] Combination Figure 12 In some embodiments, in order to facilitate the arrangement of the power cord 31, the electrical control box 10 is provided with a wiring trough 110. The power cord 31 passes through the wiring trough 110 and is electrically connected to the control circuit board 20. The wiring trough 110 provides a fixed path for the power cord 31, so that the power cord 31 will not be scattered randomly inside the electrical control box 30, keeping the inside of the electrical control box 30 tidy and improving the overall aesthetics.

[0084] The power cord 31 is effectively fixed and isolated by the cable tray 110, reducing the risk of short circuit or electric shock caused by the power cord 31 becoming loose or tangled.

[0085] In some embodiments, to reduce electromagnetic interference, the control circuit board 20 integrates a main control circuit, a frequency adjustment circuit, and a display circuit. The wiring groove 110 is located on opposite sides of the main control circuit and the frequency adjustment circuit on the housing 12 of the control box 10, allowing the power line 31 to be kept away from the main control circuit and the frequency adjustment circuit, thus reducing electromagnetic interference between the power line 31 and the main control circuit and the frequency adjustment circuit, and ensuring the stability of the control circuit board 20's operation.

[0086] In some embodiments, the control circuit board 20 consists of a first part and a second part electrically connected to the first part. The main control circuit and the frequency adjustment circuit are integrated in the first part, which is located inside the housing 11. The display circuit is integrated in the second part, which is located inside the cover 12. The first part and the second part can be arranged at an angle. The power cable 31 passes through the cable tray 11 and the wiring tray 110 and is electrically connected to the first part.

[0087] The first part integrates the control circuit and the frequency adjustment circuit. In other words, the first part combines the control function and the frequency adjustment function into one unit, 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 first part 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 first part more compact in terms of spatial layout, reducing the space occupied by multiple parts scattered.

[0088] 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.

[0089] Combination Figure 14 , Figure 15 , Figure 17 and Figure 18 In some embodiments, the refrigeration equipment includes a housing 40, which has a receiving cavity 41 and an opening 42 communicating with the receiving cavity 41. The electrical control box 10 of the electrical control component is installed in the receiving cavity 41 through the opening 42 to realize the installation of the electrical control box 10. The wire trough 11 and the cable 30 are both located in the receiving cavity 41 to facilitate the routing of the cable 30 in the receiving cavity 41.

[0090] Combination Figure 16 and Figure 19 In some embodiments, in order to ensure the stability of the electrical control box 10 installation, the electrical control box 10 is provided with a second buckle 18. The second buckle 18 abuts against the cavity wall of the receiving cavity 41. The abutment between the second buckle 18 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 41 and reducing the risk of the electrical control box falling off or loosening due to external factors such as vibration and impact.

[0091] The second clip 18 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.

[0092] Combination Figure 16 and Figure 19In 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 19. The limiting member 19 abuts against the inner wall of the opening 42. The abutment between the limiting member 19 and the inner wall of the opening 42 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 41, thereby ensuring the stability and reliability of the equipment.

[0093] In some embodiments, the limiting member 19 is set at an angle to the second buckle 18. Through the cooperation of the limiting member 19 and the second buckle 18, 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.

[0094] In some embodiments, the included angle between the limiting member 19 and the second buckle 18 can be set from 45° to 135°. In this embodiment, the included angle between the limiting member 19 and the second buckle 18 is 90°, that is, the limiting member 19 and the second buckle 18 are set perpendicularly, and this should not be construed as a limitation of this application.

[0095] In some embodiments, in order to facilitate the installation of the control box 10 into the receiving cavity 41, the end of the limiting member 19 facing away from the control box 10 has a slope. After the box body 10 is inserted into the receiving cavity 41 at an angle through the opening 42, it is necessary to push the control box 10 into the receiving cavity 41 so that the control box 10 is fully inserted into the receiving cavity 41. At this time, the slope can be transitioned so that the control box 10 is fully inserted into the receiving cavity 41.
