[0046] The following describes the electric control box 10 according to an embodiment of the present utility model with reference to the accompanying drawings.

[0047] As Figure 1 shown, the electric control box 10 according to an embodiment of the present utility model is used for an air conditioner outdoor unit 100, and the electric control box 10 includes a box body 1, a cover body 2, and a circuit board 3.

[0048] Specifically, as Figure 3 shown, the box body 1 is a plastic part, the cover body 2 is a sheet metal part and is covered on the box body 1. The cover body 2 and the box body 1 jointly define an installation space 11. The box body 1 and the cover body 2 can protect the internal structure of the electric control box 10, preventing the internal structure of the electric control box 10 from being exposed to the air conditioner outdoor unit 100 and being damaged, which is beneficial to extending the service life of the air conditioner outdoor unit 100 and has a good appearance effect. Further, as Figure 3 shown, the circuit board 3 is arranged in the installation space 11, and the electronic components and circuits for control and adjustment are arranged on the circuit board 3, which are used to control and adjust the compressor, fan, etc. in the air conditioner outdoor unit 100.

[0049] It should be noted that the box body 1 is a plastic part with good insulation, which can prevent the circuit board 3 from contacting the sheet metal structural parts of the air conditioner outdoor unit 100, and can also prevent the spread of flames after the electric control box 10 catches fire to a certain extent, ensuring the safety of the electric control box 10, improving the reliability of the air conditioner outdoor unit 100, and the plastic part is lighter in weight, which can reduce the weight of the electric control box 10, facilitate the assembly of the electric control box 10, and is convenient for the transportation of the electric control box 10; the cover body 2 is a sheet metal part with high strength, high toughness, corrosion resistance, and better fire resistance, which can improve the overall fire resistance of the electric control box 10 and the safety of the electric control box 10. Moreover, in the prior art, some electric control boxes use materials such as flame-retardant ABS (acrylonitrile-butadiene-styrene copolymer) + PVC (polyvinyl chloride), and such materials will precipitate chloride ions and corrode the circuit board under special circumstances such as high humidity. However, the cover body 2 of the present utility model is a sheet metal part, which can avoid the problem of chloride ion precipitation and corrosion of the circuit board 3, extending the service life of the circuit board 3 and ensuring the reliability of the electric control box 10.

[0050] According to the electric control box 10 of the embodiment of the present utility model, by making the box body 1 a plastic part and the cover body 2 a sheet metal part, the weight of the electric control box 10 can be reduced as much as possible, which is convenient for the assembly of the electric control box 10, facilitates the transportation of the electric control box 10, and can improve the overall fire prevention performance of the electric control box 10, prevent the flame from spreading after the electric control box 10 catches fire, and ensure the safety and reliability of the electric control box 10.

[0051] In some embodiments of the present utility model, with reference to the attached Figure 3 and the attached Figure 4 As shown, a support platform 12 is provided on the inner peripheral wall of the box body 1. The circuit board 3 is supported on the side of the support platform 12 facing the cover body 2, and the circuit board 3 abuts against the support platform 12. The support platform 12 plays a positioning role for the circuit board 3 in the up and down direction (such as Figure 3 As shown), to prevent the circuit board 3 from continuing to move towards the side away from the cover body 2, and ensure the assembly reliability and stability of the electric control box 10. It should be noted that in the prior art, usually the circuit board is first inserted obliquely into the fixed card slot of the box body, and then the circuit board is rotated and snapped into the elastic buckle position to fix the circuit board. When assembling the electric control box 10 of the present utility model, the circuit board 3 can be directly loaded into the box body 1 from top to bottom, which can reduce the assembly actions of the circuit board 3, reduce the assembly difficulty of the circuit board 3, realize the automated production of the electric control box 10, and improve the production efficiency of the electric control box 10.

[0052] In a further embodiment of the present utility model, with reference to the attached Figure 3 and the attached Figure 4 As shown, a first buckle 13 is further provided on the inner peripheral wall of the box body 1. The first buckle 13 is located on the side of the support platform 12 facing the cover body 2 and is spaced from the support platform 12. The first buckle 13 and the support platform 12 are relatively arranged in the up and down direction. The circuit board 3 is clamped between the support platform 12 and the first buckle 13. The support platform 12 can prevent the circuit board 3 from moving towards the side away from the cover body 2, and the first buckle 13 can prevent the circuit board 3 from moving towards the side close to the cover body 2. Through the cooperation of the support platform 12 and the first buckle 13, the circuit board 3 can be positioned from both sides in the thickness direction of the circuit board 3 (refer to the up and down direction shown in the attached Figure 3 ), to prevent the circuit board 3 from shaking in the installation space 11, ensure the reliable installation of the circuit board 3, and further improve the stability of the electric control box 10.

[0053] In a still further embodiment of the present utility model, with reference to the attached Figure 4As shown, the supporting platforms 12 are multiple and spaced apart along the circumferential direction of the box body 1, and the first buckles 13 are multiple and correspond to the multiple supporting platforms 12 one by one, so that the circuit board 3 can be positioned from multiple positions in the circumferential direction of the circuit board 3, thereby improving the positioning effect of the supporting platforms 12 and the first buckles 13 on the circuit board 3, further preventing the circuit board 3 from shaking in the installation space 11, ensuring the reliable installation of the circuit board 3, and thus improving the stability of the electric control box 10. For example, the supporting platforms 12 can be two, three, four, five or six and spaced apart along the circumferential direction of the box body 1, and the first buckles 13 can be two, three, four, five or six and correspond to the multiple supporting platforms 12 one by one.

[0054] In some embodiments of the present invention, refer to the attached Figure 5 and attached Figure 6 As shown in the attached reference Figure 3 The surface of the box body 1 facing the cover body 2 is provided with a slot 14, which extends along the circumferential direction of the box body 1. The outer peripheral wall of the cover body 2 is provided with a flange 21 extending in a ring shape along the circumferential direction of the cover body 2. At least part of the flange 21 is locked in the slot 14. Through the cooperation of the slot 14 and the flange 21, the cover body 2 can be positioned to ensure the relative position of the cover body 2 and the box body 1, avoid the cover body 2 from shifting in the horizontal direction, ensure the reliable installation of the cover body 2, and ensure the stability and reliability of the electric control box 10. It can be understood that the flange 21 can be only partially locked in the slot 14, or it can be completely locked in the slot 14.

[0055] In a further embodiment of the present invention, refer to the attached Figure 2 and attached Figure 5 As shown, a plurality of second clips 141 are provided on the outer wall of the slot 14, and the plurality of second clips 141 are spaced apart in the circumferential direction of the box body 1, and a snap-fitting portion 211 is provided on the outer wall of the flange 21, and the snap-fitting portion 211 cooperates with the second clip 141. The cooperation between the snap-fitting portion 211 and the second clip 141 can prevent the cover body 2 from moving toward the side away from the box body 1, avoid the cover body 2 from falling off, and ensure the reliable installation of the cover body 2. After the circuit board 3 is installed into the box body 1, the flange 21 can be aligned with the slot 14 first, and the cover body 2 can be assembled to the box body 1 from top to bottom until the snap-fitting portion 211 cooperates with the second clip 141 to complete the assembly of the electric control box 10. Since the assembly action of the electric control box 10 is simple, the automatic production of the electric control box 10 can be realized, thereby improving the production efficiency of the electric control box 10. Optionally, the clamping portion 211 may be a protrusion provided on the outer surface of the flange 21 , or may be a recessed portion recessed toward the inner side of the flange 21 .

[0056] Alternatively, if Figure 2 and Figure 3As shown, the clamping portion 211 can extend along the circumferential direction of the flanging 21. One clamping portion 211 corresponds to multiple second buckles 141, and multiple second buckles 141 are simultaneously clamped and matched with one clamping portion 211; the clamping portion 211 can also be multiple ones corresponding one by one to the multiple second buckles 141. Each second buckle 141 is matched with one clamping portion 211, and can connect the cover body 2 and the box body 1 from multiple places spaced apart in the circumferential direction of the box body 1, ensuring the assembly of the cover body 2 and the box body 1.

[0057] In a further embodiment of the present utility model, referring to the attached Figure 5 and the attached Figure 6 As shown, water-blocking ribs 142 are provided on the inner wall surface of the inner side wall of the card slot 14. The water-blocking ribs 142 are multiple ones spaced apart along the circumferential direction of the box body 1. The flanging 21 is located between the water-blocking ribs 142 and the outer side wall of the card slot 14. It can be understood that in rainy weather, the rainwater outside the air conditioner outdoor unit 100 will enter the air conditioner outdoor unit 100 and splash onto the electric control box 10. The rainwater is likely to flow into the card slot 14 from the gap between the flanging 21 and the outer side wall of the card slot 14. The setting of the water-blocking ribs 142 can block the rainwater to a certain extent, making the card slot 14 form a labyrinth waterproof structure, increasing the difficulty of the rainwater in the card slot 14 flowing to the circuit board 3, reducing the amount of water flowing to the circuit board 3, reducing the possibility of the circuit board 3 short-circuiting and catching fire, and improving the safety of the electric control box 10. For example, the water-blocking ribs 142 can be two, four, six, eight or ten spaced apart along the circumferential direction of the box body 1.

[0058] Optionally, along the length direction of the card slot 14, the opposite sides of the second buckle 141 have second notches 145. Water-blocking ribs 142 are provided on the sides facing away from each other of the two second notches 145 corresponding to the same first buckle 13. When rainwater enters the card slot 14 from the second notches 145, it can play a water-blocking role from both sides of the second notches 145, further improving the waterproof effect of the labyrinth waterproof structure, preventing the water in the card slot 14 from flowing to the circuit board 3, avoiding the circuit board 3 short-circuiting and catching fire, and improving the safety of the electric control box 10.

[0059] In a further embodiment of the present utility model, referring to the attached Figure 6 As shown, the inner side wall of the card slot 14 has a first notch 143, and a water-blocking boss 144 is provided on the inner bottom wall of the card slot 14. The water-blocking boss 144 is opposite to the first notch 143, and the water-blocking boss 144 and the support platform 12 are in the same plane. The water-blocking platform and the support platform 12 are both higher than the inner bottom wall of the card slot 14. The setting of the water-blocking boss 144 can prevent the rainwater in the card slot 14 from flowing to the support platform 12 from the first notch 143, and then flowing to the circuit board 3, thereby avoiding the circuit board 3 short-circuiting and catching fire, and improving the safety of the electric control box 10.

[0060] In some embodiments of the present utility model, referring to the attached Figure 1 As shown, one end of the box body 1 facing the fan of the air conditioner outdoor unit 100 is provided with a water baffle 15. The free end of the water baffle 15 extends downward. The setting of the water baffle 15 can prevent rainwater on the side of the electronic control box 10 facing the fan from entering the electronic control box 10, prevent the circuit board 3 from getting damp due to the entry of rainwater and causing a short circuit and fire, and improve the safety and reliability of the electronic control box 10.

[0061] In a further embodiment of the present utility model, referring to the attached Figure 2 and the attached Figure 3 As shown, the water baffle 15 is provided with a plurality of spaced-apart first micropores 151, which can increase the air volume passing through the radiator 31, improve the heat dissipation capacity of the electronic control box 10, improve the heat generation situation of the electronic control box 10, thereby reducing the probability of the electronic control box 10 catching fire, improving the safety, reliability and stability of the electronic control box 10, optimizing the user experience, and improving the reliability of the air conditioner outdoor unit 100. Moreover, the existence of the first micropores 151 can also reduce the material consumption of the water baffle 15 and reduce the production cost of the water baffle 15. It should be noted that when rainwater flows towards the water baffle 15, the first micropores 151 can reduce the flow rate of the rainwater, so that a small amount of rainwater passing through the first micropores 151 flows towards the radiator 31 instead of towards the circuit board 3.

[0062] In a further embodiment of the present utility model, referring to the attached Figure 1 and the attached Figure 2 As shown, in the direction from top to bottom (as Figure 1 shown), the water baffle 15 is inclined towards the direction close to the fan, which can increase the space between the water baffle 15 and the radiator 31, avoid affecting the normal heat dissipation of the radiator 31 due to the setting of the water baffle 15, ensure the heat dissipation air duct of the electronic control box 10, improve the heat dissipation effect of the electronic control box 10, thereby reducing the probability of the electronic control box 10 catching fire, and improving the safety and reliability of the electronic control box 10.

[0063] In some embodiments of the present utility model, referring to the attached Figure 2 As shown, a radiator 31 and a bracket 32 are provided on the side of the circuit board 3 facing away from the cover body 2. The circuit board 3, the bracket 32 and the radiator 31 are arranged and connected in the vertical direction. The radiator 31 can, through an efficient heat dissipation mechanism, quickly transfer the heat generated by electronic components such as integrated circuits in the circuit board 3 during operation, thereby controlling the temperature of the electronic components and preventing them from being damaged due to overheating, and further improving the stability and reliability of the electronic control box 10. The bracket 32 is used to connect the circuit board 3 and the radiator 31 and can play an insulating role between the circuit board 3 and the radiator 31 bracket 32, ensuring the reliability of the circuit board 3.

[0064] In a specific example, referring to the attached Figure 2As shown, the circuit board 3, the bracket 32, and the radiator 31 are sequentially connected through fasteners, which can fasten the circuit board 3, the bracket 32, and the radiator 31 together, improving the reliability and stability of the connection among the circuit board 3, the bracket 32, and the radiator 31.

[0065] In a further embodiment of the present utility model, refer to the attached Figure 2 As shown, the bracket 32 is provided with a plurality of spaced second micro-holes 321, which can increase the heat dissipation air duct on the upper side of the circuit board 3, enhance the heat dissipation capacity of the electric control box 10, improve the heat generation situation of the electric control box 10, thereby reducing the probability of the electric control box 10 catching fire, improving the safety, reliability, and stability of the electric control box 10, optimizing the user experience, and improving the reliability of the air conditioner outdoor unit 100. Moreover, the existence of the second micro-holes 321 can also reduce the material consumption of the bracket 32 and lower the production cost of the bracket 32.

[0066] In some embodiments of the present utility model, the box body 1 is a flame-retardant ABS part. The flame-retardant ABS material is an engineering plastic that adds a flame retardant to the ABS (acrylonitrile-butadiene-styrene copolymer) to achieve a flame-retardant effect. It has excellent flame-retardant performance and can effectively prevent the spread of fire when encountering a fire, improving the safety of the electric control box 10. Moreover, the flame-retardant ABS material has good comprehensive performance, high impact strength, good chemical stability, and good electrical properties. It should be noted that since the flame-retardant ABS material requires the use of a flame retardant, the cost is higher than that of sheet metal. The box body 1 of the present utility model is a flame-retardant ABS part, and the cover body 2 is a sheet metal part. This can improve the overall fire protection performance of the electric control box 10 while ensuring the overall weight of the electric control box 10 through the plastic box body 1, and reducing the use of the flame retardant and the production cost of the electric control box 10 through the sheet metal cover body 2.

[0067] Next, refer to Figures 1 to 6 Describe the electric control box 10 according to a specific embodiment of the present utility model. It should be understood that the following description is only exemplary and is intended to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0069] Furthermore, the box body 1 is a flame-retardant ABS part, the cover body 2 is a sheet metal part and is covered on the box body 1. The cover body 2 and the box body 1 jointly define an installation space 11, and the circuit board 3 is arranged in the installation space 11. This can improve the overall fire protection performance of the electric control box 10 while ensuring the overall weight of the electric control box 10 through the plastic box body 1, and reducing the use of the flame retardant and the production cost of the electric control box 10 through the sheet metal cover body 2.

[0070] Furthermore, four supporting platforms 12 and four first buckles 13 are provided on the inner circumferential wall of the box body 1. The four supporting platforms 12 are spaced apart in the circumferential direction of the box body 1. The first buckle 13 is located on the side of the supporting platform 12 facing the cover body 2 and is spaced apart from the supporting platform 12. The circuit board 3 is clamped between the supporting platform 12 and the first buckle 13. Through the cooperation of the supporting platform 12 and the first buckle 13, the circuit board 3 can be positioned from both sides in the thickness direction of the circuit board 3, avoiding the circuit board 3 from shaking in the installation space 11, ensuring the reliable installation of the circuit board 3, and thereby improving the stability of the electric control box 10.
