Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0039] This application provides an electrical control box to solve the problem of inconvenient disassembly and assembly of the box cover and body. The following description will be provided in conjunction with the accompanying drawings.
[0040] In the embodiments of this application, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the electrical control box includes:
[0041] The housing 1 has an interconnected mounting port 11 and an operating port 12. The mounting port 11 is used for inserting the power control board 4 into the housing 1, and the operating port 12 is used to expose a portion of the power control board 4 for wiring; and,
[0042] The lid 2 is disposed on the box body 1 and covers the mounting port 11 and the operating port 12;
[0043] The box body 1 and the box cover 2 are respectively provided with multiple locking blocks and multiple locking slots. Multiple or multiple locking slots are located on the periphery of the mounting port 11 and the operating port 12, and the multiple locking blocks and multiple locking slots are engaged one-to-one.
[0044] It should be noted that the electronic control board 4 refers to a board-shaped structure on which a microcontroller, power management module, drive components, input / output interfaces, and functional modules are mounted. The mounting port 11 is an opening that allows the electronic control board 4 to be inserted into the housing 1 along its length or width. The operating port 12 is an opening that exposes only a portion of the electronic control board 4 to facilitate wiring. It is conceivable that the mounting port 11 and the operating port 12 are located on different surfaces of the housing 1. Furthermore, multiple locking blocks or slots may be located on different surfaces of the housing 1.
[0045] Understandably, in related technologies, the opening of the housing 1 is usually located on the largest surface of the housing 1. This allows the entire front of the control board 4 to be exposed after the control board 4 is installed, facilitating the routing of different circuits on the control board 4. However, this requires multiple threaded holes along the edges of the housing 1 and the cover 2 to secure the housing 1 and cover 2 with bolts. Disassembly and assembly require individual operation, making the process cumbersome. In this embodiment, mounting ports 11 and operating ports 12 are provided on different surfaces of the housing 1. This reduces the size of the mounting ports 11 and operating ports 12, allowing for the installation and routing of the control board 4 without requiring large openings. Because the openings are relatively small, there are extra spaces around the mounting ports 11 and operating ports 12 for multiple locking blocks or slots, enabling quick assembly of the cover 2 and housing 1. Furthermore, the extra locking blocks and slots do not significantly increase the size of the control box, adapting to the compact installation space within the air conditioner. Meanwhile, the clips and slots located on different surfaces can fix the lid 2 and the body 1 in multiple directions. Multiple clips can be engaged with multiple slots in just one step, enabling quick assembly and disassembly of the lid 2 and the body 1.
[0046] In some embodiments, such as Figure 3 , Figure 4 as well as Figure 5 As shown, the multiple card blocks are the first card block 13 and the second card block 14 located on both sides of the mounting port 11, and the multiple card slots are the first card slot 23 and the second card slot 24. The first card block 13 is engaged with the first card slot 23, and the second card block 14 is engaged with the second card slot 24.
[0047] It should be noted that the box body 1 is provided with two locking blocks, namely the first locking block 13 and the second locking block 14 located on both sides of the mounting port 11, and the box cover 2 is provided with two locking slots in the corresponding positions.
[0048] It is understandable that by setting the two locking blocks on both sides of the mounting opening 11, after the box cover 2 is fastened onto the box body 1, the two locking blocks can be engaged with the two slots by sliding along one side of the mounting opening 11 towards the other side.
[0049] For example, the first locking block 13 and the second locking block 14 can be disposed in the plane of the mounting port 11, or the first locking block 13 can be disposed in the plane of the mounting port 11 and the second locking block 14 can be disposed in the plane of the operating port 12. The structures of the first locking block 13 and the second locking block 14 can be the same or different.
[0050] In some embodiments, such as Figure 5 and Figure 6As shown, the second locking block 14 protrudes from the end of the operating port 12 and is located close to the operating port 12. The second locking block 14 has a second wire groove 141 on the side facing the operating port 12. One end of the second wire groove 141 passes through the second locking block 14. The second wire groove 141 is used to install the wire of the temperature sensor.
[0051] It should be noted that the opening of the second wire groove 141 faces the operation port 12, and one end of the second wire groove 141 that passes through the second locking block 14 is used for the wire of the temperature sensor to be bent and extended into the second wire groove 141, or for the temperature sensing bulb of the temperature sensor to extend out of the second wire groove 141 to better sense the return air temperature of the fan. In this embodiment, the temperature sensor refers to the sensor used to detect the return air temperature of the air conditioner, so it is usually installed outside the electrical control box and close to the return air vent and the fan.
[0052] Understandably, the second clip 14 not only serves to fix the cover 2 and the body 1, but also provides wiring space for the temperature sensor, fixing and protecting the wiring of the temperature sensor, especially for the electrical control box inside the air conditioner, to prevent the wiring of the temperature sensor from being sucked into the fan.
[0053] For example, the second locking block 14 extends along the direction from the operating port 12 to the mounting port 11, and similarly, the second groove 141 extends in the same direction. The end of the second groove 141 away from the mounting port 11 passes through the second locking block 14, and the end of the second locking block 14 near the mounting port 11 is used to engage with the second locking slot 24. The end of the second groove 141 near the mounting port 11 extends in a bent manner and passes through the end of the mounting port 11 to expose the temperature sensing bulb of the temperature sensor.
[0054] In some embodiments, such as Figure 4 As shown, the cover 2 is provided with a baffle 27, which is located between the second locking block 14 and the operation port 12 and blocks the second wire groove 141.
[0055] It should be noted that the baffle 27 is used to block the opening of the second wire groove 141 facing the operation port 12. That is to say, the baffle 27 does not affect the wiring of the temperature sensor from the end of the second wire groove 141 through the second card block 14 into the second wire groove 141, or does not affect the exposure of the temperature sensing head of the temperature sensor.
[0056] Understandably, the baffle 27 further serves to protect the temperature sensor wiring, preventing the wiring from slipping out of the second wire groove 141, and the cooperation between the baffle 27 and the second locking block 14 also serves a positioning function.
[0057] For example, the side of the baffle 27 opposite to the operation port 12 is provided with a protruding structure, which is used to set the second slot 24.
[0058] In some embodiments, such as Figure 6 As shown, the edge of the operating port 12 away from the mounting port 11 is provided with a wire passage 1212. The wire passage 1212 connects the mounting port 11 and the second wire groove 141. The wire passage 1212 is used for the routing of temperature sensor wires.
[0059] It should be noted that the temperature sensor in this embodiment refers to a sensor used to detect the return air temperature of the air conditioner. Therefore, it is usually installed outside the electrical control box and near the return air vent and the fan. Understandably, the wiring channel 1212 serves to limit the wires of the temperature sensor, preventing them from being sucked in by the fan's return air.
[0060] In some embodiments, such as Figure 3 and Figure 4 As shown, the box cover 2 includes a first cover body 21 and a second cover body 22 connected at an angle. The first cover body 21 covers the mounting port 11, and the second cover body 22 covers the operation port 12. The first cover body 21 has a first slot 23 and a second slot 24 on opposite sides. The second slot 24 is located close to the second cover body 22. The first cover body 21 has a fixing hole for fasteners to pass through and connect to the box cover 2.
[0061] It should be noted that the included angle between the first cover 21 and the second cover 22 is greater than 0 degrees and less than 180 degrees. In some specific embodiments, the first cover 21 and the second cover 22 are arranged perpendicularly. Since the second locking block 14 protrudes from the end of the operating port 12 and is located close to the operating port 12, and the second locking groove 24 is located close to the second cover 22, it is easy to imagine that the second locking groove 24 is engaged with the end of the second locking block 14 near the first cover 21.
[0062] It is understandable that by setting the first slot 23 and the second slot 24 at different positions on the first cover 21, and by providing fixing holes on the first cover 21, the installation reliability of the cover 2 is improved.
[0063] In some embodiments, such as Figure 6 As shown, the edge of the operating port 12 away from the mounting port 11 is provided with a flange 121. The flange 121 is bent outward to form a wire passage 1212 with the box body 1. The flange 121 is provided with multiple wire routing grooves 1211, and the wire routing grooves 1211 are connected to the wire passage 1212.
[0064] It should be noted that the flange 121 can be a structure formed by cutting and bending the box body 1. Here, bending refers to folding the cut, uncut part to the outside of the box body 1, while maintaining a gap with the outer surface of the box body 1 to form a thread passage 1212. It can be imagined that the two ends of the thread passage 1212 formed in this way are open.
[0065] It is understandable that high-voltage and low-voltage wires are fixed in different cable trays 1211 to avoid contact between them.
[0066] For example, some of the low-voltage wires and the wires of the temperature sensor can extend from the same wiring trough 1211 into the wiring channel 1212, and then the wires of the temperature sensor pass through the wiring channel 1212 and extend into the second wiring trough 141.
[0067] In some embodiments, such as Figure 5 and Figure 6 As shown, multiple cable trays 1211 are connected to the mounting port 11, and at least one cable tray 1211 passes through the flange 121.
[0068] Understandably, due to the special shape of the flange 121, the wiring trough 1211, after connecting with the mounting port 11, can have an approximately U-shaped structure, which facilitates wiring and allows for better control of the wiring. The wiring trough 1211 that runs through the flange 121 can be used for low-voltage wiring.
[0069] In some embodiments, such as Figure 7 and Figure 8 As shown, the flange 121 is provided with multiple blocks 1213, which together with the flange 121 or the box 1 restrict the wiring.
[0070] It should be noted that the stop 1213 can be set on the side of the flange 121 facing or away from the box 1, or it can be protrudingly set on the side wall of the wiring groove 1211.
[0071] It is understandable that by adjusting the position of the stop 1213, the stop 1213 can cooperate with the side wall of the flange 121 or the cable tray 1211, thereby reducing the cable routing space and better securing the high-voltage and low-voltage wires that run through the cable tray 1211.
[0072] For example, each wiring trough 1211 has at least one stop 1213 on its side wall; the flange 121 has multiple stops 1213 on the side facing the housing 1, and the multiple stops 1213 together with the housing 1 limit the wire of the temperature sensor.
[0073] In some embodiments, such as Figure 4 and Figure 5 As shown, the first cover 21 is provided with a clearance hole 211, a third slot 25 and a fourth block 26. The clearance hole 211 passes through any side of the first cover 21 and communicates with the inside of the box 1. The third slot 25 is used for the display light box 3 to be snapped in. The fourth block 26 is located on the side of the first cover 21 and is used for the display light box 3 to be snapped in.
[0074] Understandably, the clearance hole 211 is used for wiring of the display light box 3. The third and fourth locking blocks 26, positioned in different directions, provide a more secure fixation for the display light box 3, improving connection reliability.
[0075] This application also provides an air conditioner, which includes a temperature sensor, an electronic control board 4, and the aforementioned electronic control box. The specific structure of the electronic control box is as described in the above embodiments. Since this air conditioner 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 described in detail here.
[0076] In some embodiments, the air conditioner further includes a housing and a fan assembly and a heat exchanger disposed within the housing, with an electrical control box disposed on the housing.
[0077] It should be noted that the term "air conditioner" here includes both the indoor and outdoor units, or it can refer to either the indoor or outdoor unit.
[0078] In the above embodiments, the descriptions of each embodiment have different focuses. Parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments. In the description of this application, 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.
