Description

Technical Field

[0001] This application relates to, but is not limited to, the field of household appliance technology, specifically referring to an air conditioner. Background Technology

[0002] In related technologies, the air conditioner's control box is surrounded by a foam sealant located below a partition. The air conditioner's temperature sensing wire (the wire of the temperature-sensing component that detects the outlet air temperature) and water pump wires, among others, emerge from the partition and merge with the motor / room temperature sensing wire (the wire of the temperature-sensing component that detects the room temperature). They then extend into the control box via multiple wiring holes in the foam sealant below the partition, following two or more paths. Therefore, this design requires at least three wiring holes: one in the partition and the others in the foam sealant. Due to the large number of wiring holes, the wiring routing is complex. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide an air conditioner that can reduce the number of reserved wiring holes, which is beneficial to simplifying the wiring structure.

[0004] This application provides an air conditioner, including: a housing; a partition plate disposed within the housing, the partition plate having a wiring hole; an electrical control box disposed within the housing, the electrical control box having a waterproof structure; and a wiring component disposed within the housing, the wiring component and the electrical control box being located on the same side of the partition plate in the thickness direction, the wiring component having a wiring groove, the wiring groove communicating with the wiring hole so that a wire from the other side of the partition plate in the thickness direction can enter the wiring groove through the wiring hole, the wiring groove being configured to allow a wire to pass through to connect to the electrical control box, and the wiring component being disposed adjacent to the electrical control box so that a wire passing through the wiring groove can pass over the wiring component to connect to the electrical control box.

[0005] The air conditioner provided in this application embodiment adds a wiring component, utilizing the wiring holes in the partition and the wiring grooves in the wiring component to guide the wires on both sides of the partition to connect to the electrical control box. Because the wiring component is adjacent to the electrical control box, the wires in the wiring groove can directly pass through the wiring component and extend into the electrical control box, without needing to pass through the wiring holes on the lower side of the partition as in related technologies, thus reducing wiring difficulty. Therefore, the air conditioner only needs to reserve one wiring hole on the partition, reducing the number of reserved wiring holes, simplifying the air conditioner's wiring structure, and reducing the number of wiring holes requiring sealing, thereby reducing sealing difficulty and improving sealing performance.

[0046] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0047] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown in the figure, this application provides an air conditioner, including: a housing 1, a partition 2, an electrical control box 3, and wiring components 4.

[0048] Specifically, the partition 2 is located inside the housing 1, and the partition 2 is provided with a wire passage hole 21, such as... Figure 3 As shown. The electrical control box 3 is located inside the housing 1, and the electrical control box 3 has a waterproof structure.

[0049] like Figure 2 As shown, the wiring component 4 is located inside the housing 1. The wiring component 4 and the electrical control box 3 are located on the same side of the thickness direction of the partition plate 2. The wiring component 4 is provided with a wiring groove 41, such as... Figure 2 and Figure 3 As shown, the wiring trough 41 is connected to the through hole 21 so that the wire on the other side of the thickness direction of the partition plate 2 can pass through the through hole 21 and enter the wiring trough 41. The wiring trough 41 is configured to allow the wire to pass through and connect to the electrical control box 3, and the wiring component 4 is arranged adjacent to the electrical control box 3 so that the wire passing through the wiring trough 41 can pass over the wiring component 4 and connect to the electrical control box 3.

[0050] The air conditioner provided in this embodiment adds a wiring component 4, using the wiring holes 21 in the partition 2 and the wiring grooves 41 of the wiring component 4 to guide the wires on both sides of the partition 2 to connect to the control box 3. Since the wiring component 4 is adjacent to the control box 3, the wires in the wiring grooves 41 can directly pass through the wiring component 4 and enter the control box 3, without needing to pass through the wiring holes 21 on the lower side of the partition 2 as in related technologies, thus reducing wiring difficulty. Therefore, the air conditioner only needs to reserve one wiring hole 21 on the partition 2, reducing the number of reserved wiring holes 21, simplifying the air conditioner's wiring structure, and reducing the number of wiring holes 21 that need to be sealed, thereby reducing sealing difficulty and improving sealing effect.

[0051] In some exemplary embodiments, considering the structure of the air conditioner itself, the air conditioner can be the indoor unit of a split-type air conditioner, or it can be the entire split-type air conditioner (casing 1 refers to the casing 1 of the indoor unit); the air conditioner can also be an integrated air conditioner. From the perspective of usage scenarios, the air conditioner can be, but is not limited to, a kitchen air conditioner or a bathroom air conditioner. From the perspective of installation methods, the air conditioner can be, but is not limited to, a recessed air conditioner. A recessed air conditioner can be embedded in the ceiling of a kitchen or bathroom.

[0052] In some exemplary embodiments, the housing 1 includes a housing body 11 and a panel device 12, such as Figure 1 , Figure 17 , Figure 18 and Figure 19 As shown. The panel device 12 is located on the lower side of the housing body 11 and is connected to and covers the housing body 11. The partition 2 is located inside the housing body 11 and divides the internal space of the housing body 11 into a fan chamber 14 and a heat exchange chamber 15, as shown. Figure 8 As shown. The electrical control box 3 and the wiring component 4 are located on the lower side of the heat exchange chamber 15.

[0053] Taking a built-in air conditioner as an example, after installation, such as Figure 17 and Figure 18As shown, the panel device 12 is at the bottom, and the main body 11 is at the top. However, during the assembly process before leaving the factory, the air conditioner can be reversed, i.e., the main body 11 is at the bottom and the panel device 12 is at the top, to reduce the difficulty of assembling the air conditioner. The vertical direction indicated in the accompanying drawings of this application is based on the assembled state after leaving the factory.

[0054] The panel assembly 12 may include a panel frame and a panel. The panel frame may have a certain thickness, such as... Figure 19 As shown, the interior has sufficient space to accommodate the electrical control box 3, wiring components 4, and part of the air conditioner's drip tray 5 within the panel frame. The electrical control box 3 and wiring components 4 are located below the drip tray 5. A sealing structure, such as a foam sealant 17, can be installed below the drip tray 5. This sealing structure avoids obstructing the electrical control box 3 and wiring components 4, facilitating wiring and maintenance. The panel is located at the lower end of the panel frame and can be flush with the ceiling. The panel can include return air vents, air outlets, and access panels. The electrical control box 3 can be positioned corresponding to the access panel for easy maintenance.

[0055] A fan assembly 6 can be installed inside the fan cavity 14, such as... Figure 2 As shown, the fan assembly 6 may include a motor 62, a fan wheel 63, a volute 61, and other structures. A heat exchanger 7, a water pump 8, and other structures may be installed inside the heat exchange chamber 15. A water collection tray 5 is installed on the lower side of the heat exchanger 7, and the water pump 8 can discharge the water from the water collection tray 5. The return air outlet can be connected to the fan chamber 14. The air outlet can be connected to the heat exchange chamber 15. The partition 2 may have a ventilation opening connecting the fan chamber 14 and the heat exchange chamber 15. In this way, the motor 62 drives the fan wheel 63 to rotate, and indoor air can enter the fan chamber 14 through the return air outlet, then enter the heat exchange chamber 15 to exchange heat with the heat exchanger 7, and finally be discharged into the room through the air outlet.

[0056] In some exemplary embodiments, such as Figure 9 As shown, the air conditioner also includes a seal 13, which is disposed between the partition 2 and the panel device 12 to seal the gap between the partition 2 and the panel device 12.

[0057] Since air flows from the fan chamber 14 to the heat exchange chamber 15, and the air entering through the return air inlet may carry oil or water vapor, it can reach the electrical control box 3 through the gap between the partition 2 and the panel device 12. Therefore, a seal 13 is provided between the partition 2 and the panel device 12 to separate the electrical control box 3 from the fan chamber 14, preventing the oil or water vapor in the fan chamber 14 from corroding or contaminating the electrical control box 3. Meanwhile, the water vapor and oil vapor in the heat exchange chamber 15 can be isolated by the water collection tray 5 and the aforementioned foam seal 17, preventing corrosion or contamination of the electrical control box 3.

[0058] As for the material of the seal 13, there are no restrictions; it can be sealing sponge, sealing rubber, or other materials.

[0059] In some exemplary embodiments, such as Figure 3 As shown, the wire hole 21 is located at the bottom of the partition plate 2 and extends through the lower end of the partition plate 2. The partition plate 2 is provided with a first buckle 22, which is located at the wire hole 21 and is configured to fix the wire passing through the wire hole 21.

[0060] In this way, the cable can be directly pressed into the cable guide hole 21 from the bottom of the partition plate 2 (during the assembly process before leaving the factory, it can be directly pressed downwards into the cable guide hole 21) without having to align it with the cable guide hole 21 and pass through it, thus reducing the difficulty of cable routing. After the cable is pressed into the cable guide hole 21, it is restricted by the first latch 22 and cannot be arbitrarily dislodged from the cable guide hole 21, thereby improving the positional stability and reliability of the cable.

[0061] In some embodiments, combined with Figure 2 and Figure 3 It can be seen that the wire hole 21 is located on one side of the length direction of the wiring trough 41, specifically on the side of the wiring trough 41 near the motor 62 of the fan assembly 6. This facilitates the entry of the motor 62 wire into the heat exchange chamber 15 through the wire hole 21, and then to the electrical control box 3 via the wiring trough 41.

[0062] like Figure 2 As shown, the first buckle 22 is located on the side wall of the wire hole 21 near the wire groove 41, which helps to prevent the wire in the wire hole 21 from coming out of the wire hole 21.

[0063] A first wire-passing opening 221 is formed between the first buckle 22 and the side wall of the wire-passing hole 21 away from the wire-passing groove 41, such as Figure 11 As shown, the width B of the first wire passage opening 221 is less than or equal to the diameter d of the wire, which helps to prevent the wire inside the wire passage hole 21 from coming out of the wire passage hole 21.

[0064] In some examples, 0.75 ≤ B / d ≤ 0.95 is beneficial for preventing the thread from coming off the loop and also facilitates the smooth passage of the thread through the first thread opening 221. Of course, the value of B is not limited to the above range and can be adjusted as needed.

[0065] In some embodiments, such as Figure 2 As shown, the air conditioner also includes a water tray 5 housed inside the casing 1. A wiring component 4 and an electrical control box 3 are arranged side-by-side on the underside of the water tray 5. The wiring component 4 can be fixed to the bottom wall of the water tray 5, for example, by using screws or other fasteners. The wiring component 4 and the electrical control box 3 can be arranged side-by-side along the thickness direction of the partition 2, and the distance between the wiring component 4 and the partition 2 can be less than the distance between the electrical control box 3 and the partition 2.

[0066] like Figure 10 As shown, the first buckle 22 has a guide slope 222 on the wall facing the water receiving tray 5, and a second wire passage opening 223 is formed between the guide slope 222 and the water receiving tray 5, as shown. Figure 6 and Figure 7 As shown, the minimum width A of the second through-line opening 223 is less than or equal to the diameter d of the line.

[0067] In this way, the wiring process within the fan cavity 14 is unrestricted. Wiring can be carried out before or after the water tray 5 is installed. This allows the wiring of exhaust fans and other post-installed components in bathrooms and other similar settings to be carried out after the water tray 5 is assembled, thus improving the flexibility of air conditioning wiring.

[0068] In some examples, 0.75 ≤ A / d ≤ 0.95, which is beneficial for preventing the thread from coming off and also facilitates the smooth passage of the thread through the second thread opening 223. Of course, the size of A is not limited to the above range and can be adjusted as needed.

[0069] In some exemplary embodiments, the partition 2 is provided with a second latch 23 on the side wall near the wiring component 4, such as... Figure 3 As shown. The second buckle 23 is located between the wire hole 21 and the wiring component 4, and is configured to fix the wire between the wire hole 21 and the wiring groove 41.

[0070] In this way, the wires inside the heat exchange chamber 15 (such as the wires of the water pump 8, or the wires of the temperature sensing element used to detect the outlet air temperature) can extend into the wiring groove 41 via the second latch 23, and then pass over the wiring component 4 to connect to the electrical control box 3. The wires inside the fan chamber 14 (such as the wires of the motor 62, or the wires of the temperature sensing element used to detect the room temperature) can enter the heat exchange chamber 15 through the wire hole 21, then extend into the wiring groove 41 via the second latch 23, and then pass over the wiring component 4 to connect to the electrical control box 3. This arrangement helps to improve the stability and reliability of the wire fixing.

[0071] In some embodiments, such as Figure 2 , Figure 3 and Figure 6 As shown, the wiring component 4, the second clip 23, and the wire passage hole 21 are arranged sequentially along the length of the middle partition 2. The second clip 23 has a third wire passage opening 234 at one end near the wire passage hole 21, as shown... Figure 10 As shown, the width C of the third wire opening 234 is less than or equal to the diameter d of the wire, which helps to prevent the wire inside the second buckle 23 from coming out.

[0072] In some examples, 0.75 ≤ C / d ≤ 0.95 is beneficial for preventing the thread from coming off the loop and also facilitates the smooth passage of the thread through the third thread guide opening 234. Of course, the value of C is not limited to the above range and can be adjusted as needed.

[0073] The second buckle 23 may be equipped with a guide structure 233, such as Figure 7 As shown, the guide structure 233 is located at the third wire passage opening 234, facilitating the smooth insertion of the wire into the second latch 23. The second latch 23 may include a baffle 231 and an elastic arm 232 connected at one end to the baffle 231. The other end of the elastic arm 232 may be provided with a guide structure 233, which may be V-shaped with its opening facing away from the baffle 231. Figure 7 As shown, the gap between the V-shaped tip of the guide structure 233 and the baffle 231 is the third wire passage opening 234.

[0074] In some exemplary embodiments, such as Figure 2 and Figure 6 As shown, a volute 61 is also provided inside the housing 1, and the volute 61 is located on the other side of the thickness direction of the middle partition 2. The volute 61 is provided with a third latch 611, such as... Figure 2 and Figure 12 As shown, the third clip 611 is configured to secure the wire of the temperature sensing element. The temperature sensing element can be a temperature sensing element inside the fan cavity 14 used to detect room temperature.

[0075] In some embodiments, such as Figure 4 and Figure 12 As shown, the third latch 611 includes a first wire-locking portion 6111 and a first wire-pressing portion 6112 that are staggered along the circumferential and radial directions of the volute 61. The first wire-locking portion 6111 is configured to prevent the wire from disengaging from the third latch 611 along the axial direction of the volute 61. The first wire-pressing portion 6112 is located radially outside the first wire-locking portion 6111 and is configured to cooperate with the first wire-locking portion 6111 to prevent the wire from disengaging from the third latch 611 along the radial direction of the volute 61. The staggered design makes it easy for the wire of the temperature sensing element to be locked into the third latch 611 and difficult to disengage.

[0076] like Figure 4 and Figure 12 As shown, there can be multiple first wire-locking portions 6111, which are arranged side-by-side at intervals approximately along the circumference of the volute 61. There can also be multiple first wire-pressing portions 6112, which are arranged side-by-side at intervals approximately along the circumference of the volute 61. The multiple first wire-pressing portions 6112 and the multiple first wire-locking portions 6111 are arranged alternately in both the circumferential and radial directions of the volute 61.

[0077] In some embodiments, such as Figure 4As shown, the first locking part 6111 includes a connecting part 6113 connected to the volute 61 and a bent part 6114 connected to the connecting part 6113. Figure 13 As shown, the radial distance E between the connecting portion 6113 and the first pressing portion 6112 is less than or equal to the diameter d of the wire. Figure 13 As shown, the axial distance F between the bent portion 6114 and the first pressing portion 6112 is less than or equal to the diameter d of the wire. A fourth wire passage opening 6115 is formed between the bent portion 6114 and the adjacent first pressing portion 6112, as shown. Figure 12 As shown, the width G of the fourth wire opening 6115 is less than or equal to the diameter d of the wire. This helps prevent the wire from coming off the loop.

[0078] In some examples, 0.75≤E / d≤0.85, F=0.5d, 0.9≤G / d≤1. This helps prevent the wire from coming off the clip and also makes it easier for the wire of the temperature sensing element to be engaged with the third clip 611.

[0079] Of course, the dimensions of E, F, and G are not limited to the above range and can be adjusted as needed.

[0080] In some embodiments, a motor 62 is also provided inside the housing 1, and the volute 61 and the motor 62 are arranged sequentially along the axial direction of the volute 61, such as... Figure 2 As shown, the third latch 611 is located on the side of the volute 61 closest to the motor 62. The wire passage hole 21 can be located on the side of the motor 62 furthest from the volute 61, that is: the volute 61, motor 62, and wire passage hole 21 are arranged sequentially along the axial direction of the volute 61. The axial direction of the volute 61 is consistent with the length direction of the wire routing groove 41.

[0081] like Figure 4 As shown, the volute 61 is also provided with a fourth latch 612, which is configured to fix the portion of the wire of the temperature sensing element located between the third latch 611 and the wire passage hole 21. In the thickness direction of the partition plate 2, the fourth latch 612 is located between the third latch 611 and the wire passage hole 21. In the axial direction of the volute 61, the fourth latch 612 is located on the side of the third latch 611 away from the motor 62.

[0082] In this way, the wire of the temperature sensing element needs to pass through the third clip 611, around the fourth clip 612 to reach a position near the middle partition 2, and then extend along the middle partition 2 to the wire hole 21, then through the wire hole 21 into the heat exchange chamber 15, and then through the second clip 23 and the wiring groove 41 to reach the electrical control box 3. The fourth clip 612 can effectively reduce the risk of the temperature sensing element wire being damaged by being caught in the impeller 63 due to airflow, and the wire of the temperature sensing element is double-fixed by the third clip 611 and the fourth clip 612, which has higher reliability and effectively reduces the risk of temperature sensing element failure.

[0083] The fourth buckle 612 has a fifth wire passage opening 6123, such as Figure 14 As shown, the width D of the fifth wire opening 6123 is less than or equal to the diameter d of the wire. This helps prevent the wire of the temperature sensing element from detaching from the fourth clip 612.

[0084] In some examples, 0.75 ≤ D / d ≤ 0.95 is beneficial for preventing the thread from coming off the loop and also facilitates the smooth passage of the thread through the fifth thread guide opening 6123. Of course, the size of D is not limited to the above range and can be adjusted as needed.

[0085] The fifth buckle 42 may also include a second wire-locking portion 6121 and a second wire-pressing portion 6122, which are generally arranged opposite to each other along the circumference of the volute 61. The second wire-locking portion 6121 may be generally L-shaped, and the second wire-pressing portion 6122 may be generally straight.

[0086] In some exemplary embodiments, the wiring component 4 is provided with a fifth latch 42 and a sixth latch 43, such as Figure 5 and Figure 15 As shown. The fifth clip 42 and the sixth clip 43 are arranged opposite each other along the width direction of the cable tray 41, and are configured to fix the cable in the cable tray 41. The fifth clip 42 and the sixth clip 43 can be arranged in groups, and multiple groups can be arranged at intervals along the length direction of the cable tray 41.

[0087] Since the wires in the fan cavity 14 and the heat exchange cavity 15 are combined and extended to the electrical control box 3 through the wiring trough 41, a fifth buckle 42 and a sixth buckle 43 are provided at the wiring trough 41 to facilitate multiple wires to be inserted into the wiring trough 41 together and to prevent them from coming off easily.

[0088] A sixth thread-passing opening 44 is formed between the fifth buckle 42 and the sixth buckle 43, such as Figure 16 As shown, the width I of the sixth wire passage opening 44 is less than or equal to the diameter d of the wire. This helps prevent the wire from detaching from the wire passage 41.

[0089] In some examples, 0.75 ≤ I / d ≤ 0.85 is beneficial for preventing the thread from coming off the loop and also facilitates the smooth passage of the thread through the sixth thread opening 44. Of course, the value of I is not limited to the above range and can be adjusted as needed.

[0090] In some embodiments, the fifth buckle 42 is provided with a guide bevel 421, such as Figure 5 and Figure 16 As shown, the lower end of the guide bevel 421 is lower than the lower end of the sixth latch 43, and the height difference H between the lower end of the guide bevel 421 and the lower end of the sixth latch 43 is less than the diameter d of the wire body, that is, H < d and H > 0. This helps to reduce the difficulty of wiring in the wiring trough 41 and improves the convenience of wiring.

[0091] In some embodiments, 1mm ≤ H ≤ 3mm. Of course, the size of H is not limited to the above range and can be adjusted as needed, for example, based on the elasticity of the fifth buckle 42.

[0092] In some exemplary embodiments, the housing 1 is provided with a clearance opening 16, such as... Figure 17 and Figure 18 As shown. The electrical control box 3 is provided with a wiring hole 31 that communicates with the clearance opening 16, as shown. Figure 18 and Figure 20 As shown. The wiring hole 31 is configured to allow wires passing through the clearance opening 16 to extend into the electrical control box 3. In other words, external wires 9 (such as power cords) can extend into the electrical control box 3 through the clearance opening 16 and the wiring hole 31 to connect with the motherboard or other components inside the electrical control box 3.

[0093] The bottom wall of the wiring hole 31 is provided with a guide slope 321, such as... Figure 18 and Figure 27 As shown. Along the direction close to the clearance opening 16, the guide slope 321 extends downwards at an angle. The waterproof structure includes the guide slope 321.

[0094] In this way, the water droplets on the outer wire body 9 can flow downward and outward along the guide slope 321 under the action of gravity, and cannot enter the electrical control box 3 against the force of gravity, thereby protecting the components inside the electrical control box 3 and improving the waterproofness of the electrical control box 3.

[0095] In some embodiments, the electrical control box 3 is provided with a wire clamp 34, such as Figure 18 , Figure 21 and Figure 27 As shown, the positions of the wire clamp 34 and the clearance opening 16 are both higher than the guide slope 321. The wire clamp 34 is configured to press down the wire passing through the cable hole 31 so that the wire forms a backflow bend 91 above the guide slope 321 within the cable hole 21, as shown. Figure 26 and Figure 27 As shown.

[0096] In this way, the water droplets on the outer wire 9 can accumulate and gather along the outer wire 9 towards the return water bend 91 under the action of gravity, and finally drip down to the guide slope 321, and then be discharged to the outside of the electrical control box 3 along the guide slope 321, thereby playing a better protective role for the components inside the electrical control box 3 and improving the waterproofness of the electrical control box 3.

[0097] The specific structure of the wire clamp 34 is not limited, as long as it can hold the wire in place and ensure that the wire forms a return bend 91 above the guide slope 321 in the wire hole 31.

[0098] In some exemplary embodiments, the electrical control box 3 includes a cover 32 and a body 33, such as Figure 20 and Figure 28 As shown, the lid 32 is located on the lower side of the box body 33 and is connected to the box body 33 to close it.

[0099] Box 33 has a notch 331, such as Figure 29 As shown, a sealing gasket 332 is provided at the notch 331, such as Figure 20 and Figure 22 As shown, the sealing gasket 332 has a wire-passing gap 3320 for the wire to pass through. Thus, when the wire passes through the wire-passing gap 3320, it fills the gap, achieving a preliminary seal and preventing moisture from entering the electrical control box 3. The waterproof structure includes the sealing gasket 332.

[0100] The material of the sealing gasket 332 can be, but is not limited to, rubber, silicone, etc. The method of fixing the sealing gasket 332 is unrestricted. For example, one of the outer wall of the sealing gasket 332 and the box body 33 can have a sealing groove, and the other can have a sealing rib. The sealing rib can be embedded in the sealing groove, allowing the sealing gasket 332 to be fixed at the notch 331 by an interference fit. Alternatively, the box body 33 can have a limiting groove communicating with the notch 331, and a portion of the sealing gasket 332 can be confined within the limiting groove.

[0101] like Figure 20 As shown, the number of notches 331 and sealing gaskets 332 can be multiple, depending on the wiring requirements. In one example, notches 331 and sealing gaskets 332 are provided on multiple side walls of the housing 33, with multiple notches 331 and sealing gaskets 332 provided on the side wall facing the wiring component 4, such as... Figure 5 and Figure 20 As shown, this facilitates the connection between the wires in the wiring trough 41 and the electrical control box 3.

[0102] In some embodiments, the lower end of the notch 331 is open, such as... Figure 29 As shown, the thread guide gap 3320 includes a first gap 3321 and at least one second gap 3322. The first gap 3321 penetrates the lower end of the sealing gasket 332, and the second gap 3322 intersects with the first gap 3321. In this way, the thread can be pressed into the second gap 3322 through the lower end of the first gap 3321 (during the assembly process before leaving the factory, it can be directly pressed down into the thread guide gap 3320), making installation simple and quick.

[0103] In some embodiments, the cover 32 and the body 33 together form a wiring hole 31, such as Figure 20 As shown. The flow guide slope 321 is provided on the cover 32.

[0104] In some exemplary embodiments, the lid 32 is provided with a sealing flange 323, such as Figure 20 As shown, the sealing flange 323 is pressed against the lower part of the sealing gasket 332 and can press and fix the wire passing through the wire gap 3320. In this way, the sealing flange 323 of the cover 32 can press the wire to form a secondary seal, which helps to prevent moisture from entering the electrical control box 3 through the wire gap 3320.

[0105] In some exemplary embodiments, one end of the box body 33 and one end of the box cover 32 are provided with an anti-detachment slot 322 (e.g. Figure 23 and Figure 28 As shown), the other has an anti-detachment fold edge 334 (as shown). Figure 20 , Figure 21 (As shown). The other end of the box 33 is provided with an anti-detachment buckle 333, as shown. Figure 22 As shown.

[0106] The anti-detachment slot 322 and the anti-detachment folding edge 334 are inserted and limited, and the other end of the box cover 32 is embedded in the anti-detachment buckle 333 so that the box body 33 and the box cover 32 are pre-positioned.

[0107] In this way, during the assembly of the box body 33 and the lid 32, the box body 33 and the lid 32 can be pre-positioned, freeing up both hands, and then the lid 32 and the box body 33 can be fixedly connected by screws or other fasteners. Accordingly, screw holes 37 are provided on the box body 33 and the lid 32.

[0108] In some embodiments, the anti-detachment buckle 333 extends along the length of the box body 33 to both ends of the box body 33, such as... Figure 28 and Figure 30 As shown. In this way, the contact area between the anti-detachment buckle 333 and the lid 32 is larger, and the limiting effect is better.

[0109] In some embodiments, the anti-detachment buckle 333 is provided with a guide flange 3331, such as Figure 30 As shown, the guide flange 3331 is configured to guide the edge of the cover 32 into the anti-disengagement buckle 333. This facilitates the smoother insertion of the other end of the cover 32 into the anti-disengagement buckle 333, preventing jamming or other issues, thereby improving the assembly efficiency of the electrical control box 3.

[0110] In some embodiments, the anti-detachment buckle 333 forms a groove with an opening facing the anti-detachment slot 322, such as... Figure 30 As shown, the guide flange 3331 is provided at the opening of the groove. The anti-detachment flange 334 extends away from the anti-detachment buckle 333, as... Figure 21 As shown. The anti-detachment groove 322 is located at the end of the sealing flange 323 along its length, as... Figure 23 and Figure 28As shown. Thus, the engagement between the anti-detachment buckle 333 and the edge of the lid 32 restricts the lid 32 from sliding towards the anti-detachment fold 334, and also prevents the lid 32 from falling downwards. The engagement between the anti-detachment fold 334 and the anti-detachment groove 322 restricts the lid 32 from falling downwards, and also, to a certain extent, restricts the lid 32 from sliding along the length of the box body 33.

[0111] In some exemplary embodiments, the wiring portions of the housing 33 and the lid 32 are provided with a thickened overlapping structure 35, which helps to prevent the wiring from being cut. The wiring portions may include the periphery of the wiring hole 31 and the periphery of the wiring gap. The thickened overlapping structure 35 can be formed by partially bending and overlapping the housing 33 or the lid 32.

[0112] In some examples, the housing 33 and the cover 32 have a thickened edge structure 35 around the wiring hole 31, such as... Figure 22 , Figure 24 and Figure 30 As shown, this helps prevent the wires inside the wiring hole 31 from being cut. The sealing edge 323 of the cover 32 has a thickened overlapping structure 35 at its end, such as... Figure 28 As shown, this helps prevent the wires inside the wiring gaps from being cut.

[0113] In some exemplary embodiments, the box body 33 and the box cover 32 are sheet metal parts. Combined with the sealing structure of the electrical control box 3, they can effectively prevent flames from escaping outside the electrical control box 3 after a fire starts inside, thereby improving fire resistance.

[0114] In some exemplary embodiments, the lid 32 is provided with a marking 324, such as Figure 20 As shown, the label 324 is configured to guide the installation direction and / or removal direction of the cover 32. Therefore, the label 324 plays an important role in the installation and removal of the cover 32 of the electrical control box 3, and helps to improve the efficiency of the installation and removal of the cover 32.

[0115] The identifier 324 can be, but is not limited to, pointing arrows. For example: Figure 20 As shown, the lid 32 has an arrow indicating the direction for disassembly, for example, from the anti-detachment buckle 333 to the anti-detachment groove 322. During installation, the lid 32 can be installed against the direction of the arrow until the edge of the lid 32 is inserted into the anti-detachment buckle 333 and the anti-detachment folded edge 334 is also inserted into the anti-detachment groove 322, achieving the pre-positioning of the lid 32 and the box body 33. Then, tighten the screws. For disassembly, first remove the screws, then push the lid 32 out along the direction of the arrow until the edge of the lid 32 disengages from the anti-detachment buckle 333 and the anti-detachment folded edge 334 disengages from the anti-detachment groove 322. The lid 32 can then be removed.

[0116] The box body 33 can also be fixedly connected to the water tray 5 or other structures of the air conditioner by fasteners such as locking screws, so as to ensure that the position of the box body 33 remains stable after the box cover 32 is removed during later maintenance.

[0117] In some exemplary embodiments, the housing 33 is provided with a grounding hole, through which a grounding screw 36 passes, such as... Figure 25 As shown. The grounding screw 36 serves both a grounding function and an effective fireproof function. The grounding hole of the housing 33 can be pre-installed with the grounding screw 36 during the incoming material installation.

[0118] In summary, the air conditioner provided in this application has an optimized wiring layout structure, making the wiring structure of the air conditioner simpler, the wiring efficiency higher, the sealing effect better, and the product reliability higher. In addition, the structure of the electrical control box has been improved, which can effectively prevent water condensation from entering the electrical control box, and can realize quick disassembly and assembly of the electrical control box, which is convenient for maintenance. It also has good fire resistance, and the structure is simple and the cost is low.
