[0068] The electrical control box assembly 10 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0069] As shown in Figures 4 and 6, the electrical control box assembly 10 according to an embodiment of the present invention includes an electrical control box 1 and an insect-proof mat 2.

[0070] Specifically, referring to Figures 5, 7, 22 and 23, the electrical control box 1 has a cable outlet 11, and an insect-proof pad 2 is disposed inside the cable outlet 11. The insect-proof pad 2 has multiple comb teeth 21, which are spaced apart along the axial direction of the cable outlet 11 (refer to direction b shown in Figure 22). The comb teeth 21 have multiple wire-locking slots 211, and the motor wire can be passed through the wire-locking slots 211. Understandably, in the prior art, after the cover is assembled onto the main body of the electrical control box, a large gap is left at the outlet of the wires due to the low position of the wiring, making it easy for insects to enter. However, this utility model provides an insect-proof pad 2 inside the outlet 11. The comb-like part 21 of the insect-proof pad 2 can fill the gap at the outlet 11, and the wire-locking seam 211 can be used to pass the motor wires through, which greatly reduces the area of ​​the gap at the outlet 11. This prevents insects from entering the electrical control box 1 through the outlet 11, reduces the risk of short circuits, prevents insect body fluids from reducing the insulation performance of the circuit board, protects the performance of the components inside the electrical control box 1, prevents component failure, and greatly reduces the risk of fire and electric shock, reduces safety hazards, and improves the overall reliability, stability and safety of the electrical control box assembly 10.

[0071] Furthermore, referring to Figures 17, 22, and 23, and in conjunction with Figures 16 and 21, the insect-proof mat 2 has a plurality of comb-like teeth 21 spaced apart along the axial direction of the outlet 11. The arrangement of the plurality of comb-like teeth 21 can form multiple insect-proof barriers at the outlet 11, further increasing the difficulty for insects to enter the outlet 11, reducing the possibility of insects entering the electrical control box 1, reducing the probability of short circuits, preventing component failure, reducing the possibility of fire, reducing safety hazards of the electrical control box assembly 10, and extending the service life of the electrical control box assembly 10.

[0072] According to the embodiment of the present invention, the electrical control box assembly 10 has a wire outlet 11, and an insect-proof pad 2 is disposed inside the wire outlet 11. The insect-proof pad 2 has multiple comb-like parts 21, which are spaced apart along the axial direction of the wire outlet 11. The comb-like parts 21 have multiple wire-locking seams 211, through which the motor wire can be passed. The comb-like parts 21 of the insect-proof pad 2 can fill the gap at the wire outlet 11, greatly reducing the area of ​​the gap at the wire outlet 11, preventing insects from entering the electrical control box 1 through the wire outlet 11, reducing the risk of short circuits, preventing insect body fluids from reducing the insulation performance of the circuit board, ensuring the performance of the components inside the electrical control box 1, preventing component failure, and greatly reducing the risk of fire and electric shock, reducing safety hazards, and improving the overall reliability, stability and safety of the electrical control box assembly 10.

[0073] In some embodiments of this utility model, referring to Figures 15, 24, 25 and 29, the insect-proof mat 2 also has an installation part 22. The installation part 22 extends along the circumferential direction of the outlet 11 and is detachably connected to the electrical control box 1. The peripheral wall of the installation part 22 has an opening 221. Multiple comb teeth 21 are connected to the inner wall of the installation part 22. Multiple wire-locking seams 211 are interconnected. The motor wire can be inserted into the wire-locking seam 211 through the opening 221. The installation part 22 can be used to integrate multiple comb teeth 21 into a whole. By setting the installation part 22, multiple comb teeth 21 can be simultaneously assembled into the outlet 11, which can reduce the assembly difficulty of the insect-proof mat 2 to a certain extent and facilitate the cooperation between the insect-proof mat 2 and the electrical control box 1.

[0074] In a further embodiment of this utility model, referring to Figures 10 and 12, and in conjunction with Figures 9 and 11, each comb tooth portion 21 includes a plurality of sub-teeth 212 spaced apart along the circumferential direction of the mounting portion 22. The gap between two adjacent sub-teeth 212 forms a wire-locking slot 211. The wire-locking slot 211 provides space for the motor wire, facilitating its placement. When the motor wire passes through the outlet 11, it can be located within the wire-locking slot 211. The arrangement of multiple sub-teeth 212 minimizes the gap area at the outlet 11, preventing insects from entering the electrical control box 1 through the outlet 11, reducing the risk of short circuits, preventing insect body fluids from reducing the insulation performance of the circuit board, ensuring the performance of components within the electrical control box 1, preventing component failure, and significantly reducing the risk of fire and electric shock, thereby reducing safety hazards and improving the overall reliability, stability, and safety of the electrical control box assembly 10.

[0075] Preferably, as shown in FIG24, the plurality of sub-teeth 212 of each comb tooth portion 21 are respectively a first tooth group and a second tooth group. The first tooth group and the second tooth group are respectively provided on two opposite wall surfaces in the inner wall of the mounting portion 22, and the first tooth group and the second tooth group extend toward each other. In the arrangement direction of the first tooth group and the second tooth group (refer to the d direction shown in FIG24), the first tooth group and the second tooth group are arranged at intervals.

[0076] In a further embodiment of this utility model, referring to Figure 10, the width of the wire-locking slit 211 is m, and satisfies: m≤1mm. This ensures the normal insertion of the motor wire while minimizing the distance between adjacent teeth 212, further reducing the notch area at the wire outlet 11. This prevents insects from entering the electrical control box 1 through the wire outlet 11, reducing the risk of short circuits, preventing insect body fluids from reducing the insulation performance of the circuit board, ensuring the performance of components within the electrical control box 1, preventing component failure, and significantly reducing the risk of fire and electric shock, thereby reducing safety hazards and improving the overall reliability, stability, and safety of the electrical control box assembly 10. For example, the width m of the wire-locking slit 211 can be 1mm, 0.9mm, 0.8mm, or 0.7mm.

[0077] In a further embodiment of the present invention, referring to Figures 3 and 18, the electrical control box 1 includes a box body 12 and a cover 13. The box body 12 has an opening 121. The cable outlet 11 is provided on the peripheral wall of the box body 12 and located at the end of the box body 12 with the opening 121. The cover 13 is covered at the opening 121. The mounting part 22 is snapped onto the box body 12. The opening 221 is located on the side of the mounting part 22 facing the cover 13.

[0078] Understandably, in the prior art, after the front cover is assembled onto the electrical control box body, the wiring position at the junction of the electrical control box body and the front cover is low, resulting in a large gap at the wire outlet, which makes it easy for insects to enter. However, this utility model provides an insect-proof pad 2 at the wire outlet 11 where the box body 12 and the cover body 13 meet. This allows the comb teeth 21 to fill the gap left after the motor wire is inserted into the wire outlet 11, reducing the gap area at the wire outlet 11. This prevents insects from entering the electrical control box 1 through the wire outlet 11, reducing the risk of short circuits, preventing insect body fluids from reducing the insulation performance of the circuit board, ensuring the performance of the components inside the electrical control box 1, preventing component failure, and greatly reducing the risk of fire and electric shock, reducing safety hazards, and improving the overall reliability, stability, and safety of the electrical control box assembly 10.

[0079] In a further embodiment of this utility model, referring to Figures 24 and 27, wire buckles 23 are provided on both opposite walls of the opening 221. The two wire buckles 23 extend toward each other and are spaced apart. The motor wire can be inserted into the wire-locking seam 211 through the gap between the two wire buckles 23. On the one hand, the wire buckles 23 can restrain the motor wire inserted into the outlet 11, preventing the assembled motor wire from easily coming out of the outlet 11. This can reduce the shaking amplitude of the motor wire when the number of motor wires is relatively small. On the other hand, the wire buckles 23 can also play a role in preventing insects to enter the electrical control box 1 through the outlet 11.

[0080] In a further embodiment of this utility model, referring to Figure 15, and in conjunction with Figures 13 and 14, in the direction from the cover 13 to the box 12, the two wire buckles 23 are inclined toward each other. The wire buckles 23 can guide the motor wire, so that the motor wire moves along the extension direction of the wire buckle 23 and is inserted into the wire locking seam 211 through the gap between the free ends of the two wire buckles 23, thereby facilitating the insertion of the motor wire into the outlet 11.

[0081] In a further embodiment of this utility model, referring to Figure 10, a filling part 231 is provided on the side of the wire buckle 23 facing the cover 13. The maximum distance between the filling part 231 and the cover 13 is n, and satisfies: n≤1mm. It can be understood that, due to the large gap between the wire buckle 23 and the cover 13, insects and other debris can easily enter the interior of the electrical control box 1 through the gap between the wire buckle 23 and the cover 13. The filling part 231 on the side of the wire buckle 23 facing the cover 13 can reduce the distance between the wire buckle 23 and the cover 13, preventing insects and other debris from entering the interior of the electrical control box 1 through the gap between the wire buckle 23 and the cover 13. This can reduce the risk of short circuit, prevent insect body fluids from reducing the insulation performance of the circuit board, ensure the performance of the components in the electrical control box 1, prevent component failure, reduce the risk of fire and electric shock, reduce safety hazards, and improve the overall reliability, stability and safety of the electrical control box assembly 10.

[0082] Furthermore, referring to Figure 10, and in conjunction with Figures 8 and 9, the maximum distance n between the filling part 231 and the cover 13 satisfies: n ≤ 1 mm. This ensures that the gap between the filling part 231 and the cover 13 is as small as possible, thereby greatly reducing the distance between the wire clip 23 and the cover 13. This minimizes the probability of insects and other debris entering the electrical control box 1, reducing the risk of short circuits, preventing insect body fluids from reducing the insulation performance of the circuit board, ensuring the performance of components inside the electrical control box 1, preventing component failure, reducing the risk of fire and electric shock, reducing safety hazards, and improving the overall reliability, stability, and safety of the electrical control box assembly 10. For example, the maximum distance n between the filling part 231 and the cover 13 can be 1 mm, 0.9 mm, 0.8 mm, or 0.7 mm.

[0083] In a further embodiment of this utility model, referring to Figures 3, 4 and 20, the box 12 includes a body 122 and a PCB bracket 123. The body 122 defines an opening 121, and the peripheral wall of the body 122 has a clearance opening 124 located at one end of the body 122 facing the cover 13. The PCB bracket 123 is disposed inside the body 122, and the cable outlet 11 is disposed on the peripheral wall of the PCB bracket 123 and opposite to the clearance opening 124. It should be noted that the PCB bracket 123 can be used to install the circuit board, preventing the circuit board from deforming or being damaged due to vibration, impact or external force, so that the circuit board is accurately fixed in the designated position inside the control box 1, avoiding interference with other components inside the control box 1. In addition, the body 122 is a metal part and the PCB bracket 123 is a plastic part. The setting of the PCB bracket 123 can isolate the circuit board from the body 122, avoiding the risk of short circuit or leakage due to poor insulation.

[0084] In a further embodiment of this utility model, referring to Figures 15, 24, 26 and 28, the PCB bracket 123 has a mounting hole 125. The mounting hole 125 extends along the arrangement direction of the box body 12 and the cover body 13 (refer to direction e shown in Figure 15) and penetrates the PCB bracket 123. The outer peripheral wall of the mounting part 22 has a fixing buckle 222. The fixing buckle 222 and the notch are located on opposite sides of the mounting part 22. The fixing buckle 222 is engaged in the mounting hole 125. After the insect-proof pad 2 is placed into the cable outlet 11, the cooperation between the fixing buckle 222 and the mounting hole 125 can prevent the insect-proof pad 2 from falling out towards the cover body 13, ensuring the reliability and stability of the installation of the insect-proof pad 2 and the PCB bracket 123, and improving the overall assembly reliability of the electrical control box assembly 10.

[0085] In a further embodiment of this utility model, referring to Figures 19, 22, and 23, at least one inner wall of the cable outlet 11 has a groove 111 along the circumferential direction of the housing 12. The groove 111 extends along the arrangement direction of the housing 12 and the cover 13. A support post 223 is provided on the outer peripheral wall of the mounting part 22. The support post 223 extends along the length of the insect-proof mat 2 and is disposed within the groove 111. When assembling the insect-proof mat 2 onto the PCB bracket 123, the support post 223 needs to be positioned opposite the groove 111 so that the support post 223 and the groove 111 cooperate. The entire insect-proof mat 2 is now assembled onto the PCB bracket 123 along the extension direction of the slide groove 111 (refer to direction e shown in Figure 15). Through the cooperation of the slide groove 111 and the support column 223, the slide groove 111 and the support column 223 can play a guiding role during the assembly of the insect-proof mat 2, making it easy to assemble the insect-proof mat 2 onto the PCB bracket 123. After the insect-proof mat 2 is assembled, the support column 223 and the slide groove 111 can prevent the insect-proof mat 2 from shaking in the direction perpendicular to the arrangement direction of the box body 12 and the cover body 13, and prevent the insect-proof mat 2 from coming out of the cable outlet 11, thus ensuring the reliability and stability of the installation of the insect-proof mat 2.

[0086] In a specific example, referring to Figures 19, 22, and 23, the inner walls of both sides of the outlet 11 along the circumferential direction of the housing 12 have grooves 111. The grooves 111 extend along the arrangement direction of the housing 12 and the cover 13. The mounting part 22 has support columns 223 on both sides in the width direction. The two support columns 223 are located in the two grooves 111 respectively. Through the one-to-one cooperation between the two support columns 223 and the two grooves 111, the guiding effect of the grooves 111 on the insect-proof mat 2 during the installation process can be improved, the accuracy of the installation of the insect-proof mat 2 can be improved, the assembly difficulty of the insect-proof mat 2 can be reduced, and after the insect-proof mat 2 is assembled, it can further prevent the insect-proof mat 2 from shaking in the direction perpendicular to the arrangement direction of the housing 12 and the cover 13, prevent the insect-proof mat 2 from falling out of the outlet 11, and ensure the reliability of the installation of the insect-proof mat 2.

[0087] In some embodiments of this utility model, referring to Figure 22, the minimum distance between two adjacent comb teeth 21 along the axial direction of the outlet 11 is 'a', and satisfies: a ≥ 2 mm. This facilitates the normal production and processing of the insect-proof mat 2, avoids affecting the normal demolding of the insect-proof mat 2 due to the small gap between two adjacent comb teeth 21, and can, to a certain extent, ensure the integrity of the comb teeth 21, preventing damage to the comb teeth 21 due to demolding difficulties, thereby ensuring the production feasibility of the insect-proof mat 2. For example, the minimum distance 'a' between two adjacent comb teeth 21 along the axial direction of the outlet 11 can be 2 mm, 3 mm, 4 mm, or 5 mm. In a specific example, referring to Figure 22, the minimum distance 'a' between two adjacent comb teeth 21 along the axial direction of the outlet 11 is 3.8 mm.

[0088] Preferably, the planes on which the multiple comb teeth 21 are located are parallel and perpendicular to the axial direction of the outlet 11, which can reduce the manufacturing difficulty of the comb teeth 21, facilitate the manufacturing of the insect-proof mat 2, ensure the normal demolding of the insect-proof mat 2, and improve the production feasibility of the insect-proof mat 2.

[0089] In some embodiments of this utility model, referring to Figures 3, 4 and 5, there are multiple outlet ports 11, which are spaced apart along the circumferential direction of the control box 1. The insect-proof pads 2 are multiple, each corresponding to one of the multiple outlet ports 11. The arrangement of multiple outlet ports 11 facilitates the insertion of motor wires of multiple components inside the air conditioner 100 into the control box 1, ensuring that the wiring terminals inside the control box 1 are simultaneously connected to multiple components inside the air conditioner 100.

[0090] For example, the cable outlets 11 can be two, three, or four spaced apart along the circumferential direction of the control box 1, and the insect-proof mats 2 can be two, three, or four corresponding to the multiple cable outlets 11. In a specific example, referring to Figure 3, and in conjunction with Figures 4 and 5, there are three cable outlets 11, which are spaced apart along the circumferential direction of the control box 1, and three insect-proof mats 2 corresponding to the three cable outlets 11. Among them, two of the three cable outlets 11 are located on one side of the width direction of the PCB bracket 123 (refer to direction b shown in Figure 4), and the other one of the three cable outlets 11 is located on the other side of the width direction of the PCB bracket 123.

[0091] In some embodiments of this utility model, the insect-proof mat 2 is a soft rubber part. The soft rubber part has the characteristics of good elasticity, good flexibility, good insulation, weather resistance and chemical resistance stability, which can improve the reliability, stability and safety of the insect-proof mat 2. In addition, the molding process of the soft rubber part is flexible, the production mold has a long life and the development cycle is short, which greatly reduces the production and processing difficulty of the insect-proof mat 2.

[0092] In a specific example, multiple insect-proof mats 2 are made of rubber, which gives them high elasticity and resilience. They also have weather resistance, chemical resistance, insulation and arc resistance, further ensuring the reliability and stability of the insect-proof mats 2 and extending their service life.

[0093] It should be noted that in the prior art, the wire clip is directly integrated into the inner wall of the cable outlet of the PCB bracket. The PCB bracket is a plastic part, which is relatively hard. The motor wire can only enter through the gap between the wire clip and the inner wall of the cable outlet. To prevent the motor wire in the cable outlet from coming out through the gap between the wire clip and the inner wall of the cable outlet, the gap between the wire clip and the inner wall of the cable outlet is usually small, which affects the insertion of the motor wire and results in low assembly efficiency. In this utility model, by integrating the wire clip 23 into the insect-proof mat 2, the insect-proof mat 2 is made of soft rubber, which gives the wire clip 23 a certain degree of elasticity and flexibility. It can prevent the motor wire in the wire-locking seam 211 from coming out of the cable outlet 11. When the motor wire is assembled into the cable outlet 11, the motor wire can squeeze the wire clip 23 to deform it. After the motor wire is assembled, the wire clip 23 can return to its original shape. This reduces the difficulty of inserting the motor wire into the wire-locking seam 211, and allows multiple motor wires to be inserted into the insect-proof mat 2 at the same time, greatly improving the assembly efficiency of the motor wire.

[0094] In some embodiments of this utility model, as shown in Figure 24, the insect-proof mat 2 is an integral piece, which can reduce the assembly difficulty of the insect-proof mat 2, facilitate the assembly of the insect-proof mat 2 onto the electrical control box 1, simplify the assembly process of the electrical control box assembly 10, improve the assembly efficiency of the electrical control box assembly 10, ensure the assembly accuracy of the electrical control box assembly 10, and reduce the assembly error of the electrical control box assembly 10.

[0095] This utility model also proposes an air conditioner 100 having the electrical control box assembly 10 of the above embodiments.

[0096] As shown in Figure 2, the air conditioner 100 according to an embodiment of the present invention includes a housing 20, a heat exchanger assembly 30, an air duct assembly 40, a fresh air module 50, and the aforementioned electrical control box assembly 10.

[0097] Specifically, referring to Figures 1 and 2, the housing 20 can protect the internal structure of the air conditioner 100, prevent the internal structure of the air conditioner 100 from being exposed and damaged, which helps to extend the service life of the air conditioner 100 and has a better appearance.

[0098] Furthermore, referring to Figures 1 and 2, the housing 20 includes a panel assembly 201, a top cover component 202, a chassis component 203, a rear housing component 204, and an air outlet frame component 205.

Even further, referring to Figures 1 and 2, a portion of the rear housing component 204 is connected to the lower panel 2012, and a portion is connected to the air outlet frame component 205. The ends of the rear housing component 204 and the lower panel 2012 furthest from the upper panel 2011 are both connected to the chassis component 203. The top cover component 202 is connected to the ends of the rear housing component 204 and the air outlet frame component 205 furthest from the chassis component 203, thus forming an integral structure that protects the internal structure of the air conditioner 100 and prevents users from contacting the interior and causing injury.

[0099] It should be noted that, as shown in Figures 2 and 3, the electrical control box assembly 10 is fixed to the rear housing component 204. The electrical control box assembly 10 also includes an electrical control box bracket 3. The electrical control box 1 is fixed to the rear housing component 204 through the electrical control box bracket 3, which facilitates the connection of the wiring terminal of the electrical control box 1 to the motor wires 101 of other components inside the air conditioner 100. Furthermore, referring to Figure 3, the electrical control box 1 also includes a rear cover 14, which is located on the side of the box body 12 away from the cover body 13. During the assembly of the electrical control box assembly 10, the insect-proof pad 2 is first assembled to the outlet 11 of the PCB bracket 123, then the PCB bracket 123 is assembled into the body 122, and then the assembled PCB bracket 123, body 122 and insect-proof pad 2 are assembled together onto the electrical control box bracket 3 and fixed to the rear box component 204 through the electrical control box bracket 3. After the motor wires of components such as the fresh air module 50 are installed into the box body 12, the cover body 13 is assembled onto the body 122 and fixed. Finally, after the air conditioner 100 is powered on and tested, the rear cover 14 is assembled onto the box body 12.

[0100] Furthermore, referring to Figure 2, the housing 20 has a heat exchange air duct and an air inlet 2041 and an air outlet 2051 connected to the heat exchange air duct. The air inlet 2041 is located on the rear housing component 204 and extends along the length of the rear housing component 204 (refer to the up and down direction shown in Figure 2). Airflow outside the air conditioner 100 can enter the air conditioner 100 through the air inlet 2041.

[0101] Furthermore, referring to Figures 1 and 2, an air inlet grille 2042 is provided at the air inlet 2041. On the one hand, the air inlet grille 2042 can prevent hands or other foreign objects from entering the air conditioner 100, protecting the user's safety and ensuring the normal operation of the air conditioner 100. On the other hand, the air inlet grille 2042 can prevent insects, rodents, etc. from entering the housing 20 of the air conditioner 100 and causing damage to the air conditioner 100, ensuring the normal operation of the air conditioner 100 and ensuring the aesthetic appearance of the air conditioner 100.

[0102] Optionally, the air intake grille 2042 is detachably connected to the rear housing component 204. The air intake grille 2042 can ensure the aesthetic appearance of the housing 20, and after the air intake grille 2042 is removed, it is convenient to repair and replace the components inside the air conditioner 100. At the same time, it is convenient to clean the air intake grille 2042, avoiding dust accumulation caused by prolonged use.

[0103] Furthermore, referring to Figures 1 and 2, the air outlet 2051 is provided on the air outlet frame component 205 and extends along the length direction of the air conditioner 100 (refer to the vertical direction shown in Figure 1). The airflow inside the air conditioner 100 can be blown into the room through the air outlet 2051. Furthermore, referring to Figures 1 and 2, the air outlet frame component 205 is provided with a switch door 2052, and the switch door 2052 is movable along the width direction of the air outlet 2051, so that the switch door 2052 can open or close the air outlet 2051 to cooperate with the opening or closing of the air conditioner 100.

[0104] Understandably, when the air conditioner 100 is in use, opening and closing the door 2052 can open the air outlet 2051, allowing airflow to flow into the room through the air outlet 2051; when the air conditioner 100 is turned off, opening and closing the door 2052 can close the air outlet 2051, preventing dust, insects, etc. from entering the air conditioner 100, ensuring the normal use of the air conditioner 100, and giving the air conditioner 100 a better appearance.

[0105] Furthermore, referring to Figure 2, the heat exchanger assembly 30 and the air duct assembly 40 are disposed in the heat exchange air duct. The air duct assembly 40 can drive the airflow outside the air conditioner 100 to enter the housing 20 through the air inlet 2041. The airflow inside the housing 20 can exchange heat with the heat exchanger assembly 30. The airflow after heat exchange can be blown into the room through the air outlet 2051, thereby achieving the effect of regulating the indoor temperature and meeting the user's usage needs.

[0106] Optionally, referring to Figure 2, the air inlet grille 2042 can be arranged opposite to the heat exchanger assembly 30 and the air duct assembly 40, facilitating the airflow from outside the air conditioner 100 to enter the housing 20 through the air inlet grille 2042, making the airflow smoother, increasing the air intake volume, improving the air intake efficiency of the air duct assembly 40, reducing the noise of the air conditioner 100 during operation, and improving the performance and comfort of the air conditioner 100. Preferably, as shown in Figure 2, the heat exchanger assembly 30 is located upstream of the air duct assembly 40 along the airflow direction.

[0107] Furthermore, referring to Figure 2, the fresh air module 50 is disposed inside the housing 20 and located below the heat exchanger assembly 30 and the air duct assembly 40. It is used to introduce fresh outdoor air and exhaust indoor polluted air, thereby improving indoor air quality, preventing odors and germs from growing, and enhancing the user experience.
