[0002] With the rapid development of modern technology, the air conditioner, as an indispensable electrical appliance in the home and commercial environments, its performance and stability have increasingly attracted the attention of consumers. During the operation of the air conditioner, the electronic control component, as its core control part, is responsible for regulating the operating state of the entire system, and its stability and reliability directly determine the overall performance and service life of the air conditioner.

[0003] However, in the prior art, when the electronic control component operates for a long time, its heat dissipation is poor, which is not conducive to the stability of the operation of the whole machine. Summary of the Utility Model

[0004] To solve the above technical problems, the present utility model provides an electronic control component and an air conditioner, aiming to at least solve to a certain extent the technical problem that when the electronic control component operates for a long time, its heat dissipation is poor, which is not conducive to the stability of the operation of the whole machine.

[0007] Since the installation structure has a bottom surface and an open end opposite to the bottom surface, the main board is disposed within the installation structure and has a first surface and a second surface arranged opposite to each other. The first surface faces the bottom surface, and the second surface faces the open end. A first heat dissipation channel is provided between the first surface and the bottom surface. Therefore, when the air conditioner is operating, the fan assembly within the air conditioner's cabinet operates to cause air to flow within the cabinet.

When the main board is working, the main board will generate heat radiation. The heat radiation between the first surface and the bottom surface will be drawn into the first heat dissipation channel and enter the air conditioner's cabinet through the first heat dissipation channel.

[0043] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0044] An electronic control component and an air conditioner provided in this embodiment are designed to at least solve to some extent the technical problem that when the electronic control component operates for a long time, its heat dissipation is poor, which is not conducive to the stability of the overall machine operation.

[0045] Figure 1 It is a schematic structural diagram of an electronic control component for some embodiments; Figure 2 For Figure 1 The exploded view of the electronic control component in; Figure 3 For Figure 1 The top view of the electronic control component in; Figure 4 For Figure 3 The A-A cross-sectional view of the electronic control component in. Combining Figure 1 , Figure 2 , Figure 3 And Figure 4 , the electronic control component of the embodiment of the present application includes: a mounting structure 10 and a main board 20. The mounting structure 10 has a bottom surface and an opening 101 opposite to the bottom surface. The main board 20 is disposed within the mounting structure 10 and has a first surface 201 and a second surface 202 disposed opposite to each other. The first surface 201 faces the bottom surface, and the second surface 202 faces the opening 101. Among them, a first heat dissipation channel 30 is provided between the first surface 201 and the bottom surface, and the first heat dissipation channel 30 communicates with the box body 40 of the air conditioner.

[0046] Since the mounting structure 10 has a bottom surface and an opening 101 opposite to the bottom surface, the main board 20 is disposed within the mounting structure 10 and has a first surface 201 and a second surface 202 arranged back to back. The first surface 201 faces the bottom surface, and a first heat dissipation channel 30 is provided between the first surface 201 and the bottom surface. Therefore, when the air conditioner operates, the fan assembly within the housing 40 of the air conditioner operates to cause air to flow within the housing 40. Since the first heat dissipation channel 30 communicates with the housing 40 of the air conditioner, the air within the first heat dissipation channel 30 will be drawn into the housing 40 to form a negative pressure. When the main board 20 is operating, the main board 20 will generate heat radiation. The heat radiation between the first surface 201 and the bottom surface will be drawn into the first heat dissipation channel 30 and enter the housing 40 of the air conditioner through the first heat dissipation channel 30. Under the combined action of the operation of the fan assembly and the negative pressure effect of the first heat dissipation channel 30, the heat radiation generated by the main board 20 can be effectively dissipated, so as to achieve the heat dissipation of the first surface 201, reduce the operating temperature of the main board 20, improve the stability and lifespan of the main board 20, ensure that the main board 20 can operate normally, thereby improving the overall performance and efficiency of the air conditioner. Moreover, by allowing the heat radiation of the main board 20 to enter the housing 40 through the first heat dissipation channel 30, the risk of damage to the main board 20 due to overheating can be reduced, thereby extending the service life of the main board 20. At the same time, it can reduce safety hazards such as fires caused by the high temperature of the main board 20, improving the user experience. Since the second surface 202 faces the opening 101, when the main board 20 is operating, the heat generated by the main board 20 can be directly discharged from the mounting structure 10 through the opening 101, effectively dissipating the heat generated by the main board 10, reducing the possibility of heat accumulation at the main board 10, so as to achieve the heat dissipation of the second surface 202, further reducing the operating temperature of the main board 10, further improving the stability and lifespan of the main board 20, and improving the stability and performance of the air conditioner.

[0047] In some embodiments, the first surface 201 faces the bottom surface, resulting in the first surface 201 being blocked by the bottom surface, and the heat dissipation effect between the first surface 201 and the bottom surface is poor. By providing a first heat dissipation channel 30 between the first surface 201 and the bottom surface, and the first heat dissipation channel 30 communicating with the housing 40 of the air conditioner, the heat radiation between the first surface 201 and the bottom surface is guided into the housing 40 of the air conditioner through the first heat dissipation channel 30, so as to achieve the heat dissipation of the first surface 201, enabling the heat radiation generated by the main board 20 to be effectively dissipated, reducing the operating temperature of the main board 20, improving its stability and lifespan, and ensuring that the main board 20 can operate normally, thereby improving the overall performance and efficiency of the air conditioner.

[0048] Combined Figure 1 and Figure 2, in some embodiments, the main board 20 can be installed in the installation structure 10 through the opening 101. The opening 101 enables the main board 20 to be directly aligned and inserted into the installation structure 10, simplifies the installation process, reduces the time and steps required for installation, and improves work efficiency. That is to say, the opening 101 can not only achieve heat dissipation of the second surface 202, but also facilitate the installation of the main board 20, realizing "dual use of one opening", and reducing costs.

[0049] Combined with Figure 1 and Figure 2 , in some embodiments, in order to form the first heat dissipation channel 30, the installation structure 10 includes: an electric control box 102 and a main board installation box 103. The electric control box 102 is provided with a heat dissipation slot 104 communicating with the box body 40 of the air conditioner. The main board installation box 103 is arranged in the electric control box 102 and is provided with an opening 101. Among them, the main board 20 is arranged in the main board installation box 103. The main board installation box 103 is provided with a plurality of first heat dissipation holes 105. The plurality of first heat dissipation holes 105 are located between the first surface 201 and the electric control box 102, and the plurality of first heat dissipation holes 105 communicate with the heat dissipation slot 104 to form the first heat dissipation channel 30.

[0050] In some embodiments, when the air conditioner is running, the fan assembly in the box body 40 of the air conditioner operates to make the air flow in the box body 40. Since the heat dissipation slot 104 communicates with the box body 40 of the air conditioner, the air in the heat dissipation slot 104 will be drawn into the box body 40 to form a negative pressure. When the main board 20 is working, the main board 20 will generate heat radiation. The heat radiation between the first surface 201 and the bottom surface will be inhaled into the heat dissipation slot 104 through the plurality of first heat dissipation holes 105 and enter the box body 40 of the air conditioner through the heat dissipation slot 104. Under the combined action of the operation of the fan assembly and the negative pressure effect of the heat dissipation slot 104, the heat radiation generated by the main board 20 can be effectively dissipated, so as to realize the heat dissipation of the first surface 201, reduce the working temperature of the main board 20, improve the stability and service life of the main board 20, ensure that the main board 20 can work normally, thereby improving the overall performance and efficiency of the air conditioner. Moreover, by entering the heat radiation of the main board 20 into the box body 40 through the first heat dissipation channel 30, the risk of damage to the main board 20 due to overheating can be reduced, thereby extending the service life of the main board 20. At the same time, it can reduce safety hazards such as fires caused by the high temperature of the main board 20 and improve the user experience.

[0051] Figure 9 For Figure 1 Schematic structural diagram of the main board installation box of the electric control component in the middle; Figure 10 For Figure 9 Rear view of the main board installation box in the middle. Combined with Figure 9 and Figure 10, in some embodiments, a plurality of first heat dissipation holes 105 may be arranged at intervals side by side, and the first surface 201 covers the plurality of first heat dissipation holes 105, so that the heat radiation of the first surface 201 can enter the heat dissipation groove 104 through the plurality of first heat dissipation holes 105.

[0052] In some embodiments, the main board 20 has heat generating components. Along the thickness direction of the main board installation box 103, the projection of the heat generating components 20 on the main board installation box 103 overlaps with the plurality of first heat dissipation holes 105, so that the heat radiation of the heat generating components can enter the heat dissipation groove 104 through the plurality of first heat dissipation holes 105, ensuring the heat dissipation effect.

[0053] Combined with Figure 1 and Figure 2 , in some embodiments, the main board installation box 103 is arranged in the electric control box 102. The electric control box 102 supports and accommodates the main board installation box 103, providing an installation space and support force for the main board installation box 103, ensuring that the main board installation box 103 will not shake or deform due to its own weight or external factors during installation and use. At the same time, it also protects the main board installation box 103 from being damaged by being collided with external sundries, ensuring the safety of the main board installation box 103. The main board 20 is arranged in the main board installation box 103. The main board installation box 103 supports and accommodates the main board 20, providing an installation space and support force for the main board 20, ensuring the stability of the installation of the main board 20. At the same time, it also protects the main board 20 from being damaged by being collided with external sundries, ensuring the safety of the main board 20.

[0054] Figure 12 It is a schematic structural diagram of an air conditioner in some embodiments. Combined with Figure 12 , in some embodiments, the electric control box 102 is connected to the box body 40. The box body 40 supports the electric control box 102, and can provide a stable support force for the electric control box 102, ensuring that the electric control box 102 will not shake or deform due to its own weight or external factors during installation and use.

[0055] Figure 6 It is Figure 1 a schematic structural diagram of the electric control box of the electric control component in Figure 7 It is Figure 6 a rear view of the electric control box in Figure 8 It is Figure 6 a front view of the electric control box in Figure 4 , Figure 6 , Figure 7 and Figure 8, in some embodiments, due to continuous high temperature, the main board 20 may catch fire and generate flames. To prevent the flames from entering the cabinet 40 of the air conditioner along with the airflow, the heat dissipation groove 104 includes a first groove 1041 and a second groove 1042 communicating with the first groove 1041. The depth of the second groove 1042 is greater than that of the first groove 1041, and the second groove 1042 communicates with the cabinet 40 of the air conditioner.

[0056] In some embodiments, when the air conditioner is operating, the fan assembly in the cabinet 40 of the air conditioner operates to make the air flow in the cabinet 40. Since the second groove 1042 communicates with the cabinet 40 of the air conditioner, the air in the first groove 1041 and the second groove 1042 will be drawn into the cabinet 40 to form a negative pressure. When the main board 20 is working, the main board 20 will generate heat radiation. The heat radiation between the first surface 201 and the bottom surface will be inhaled into the first groove 1041 through a plurality of first heat dissipation holes 105, enter the second groove 1042, and enter the cabinet 40 of the air conditioner through the second groove 1042. Under the combined action of the operation of the fan assembly and the negative pressure effect of the first groove 1041 and the second groove 1042, the heat radiation generated by the main board 20 can be effectively dissipated, so as to realize the heat dissipation of the first surface 201, reduce the working temperature of the main board 20, and improve the stability and service life of the main board 20.

[0057] Combined with Figure 6 , in some embodiments, when the main board 20 catches fire, since the depth of the second groove 1042 is greater than that of the first groove 1041, when the air flow enters the second groove 1042 from the first groove 1041, the air path will bend, which can change the flow direction of the air flow, increase the path length of the air flow during the passing process, and further increase the resistance when the air flow passes. Due to the increase in resistance, the flame will be hindered when following the air flow into the second groove 1042, which can effectively reduce the possibility of the flame entering the second groove 1042 and ensure the safety of the equipment in the cabinet 40 of the air conditioner.

[0058] Combined with Figure 4 and Figure 6 , in some embodiments, to further prevent the flames from entering the cabinet 40 of the air conditioner along with the air flow, the second groove 1042 includes a first sub-groove 10421 communicating with the first groove 1041 and a second sub-groove 10422 communicating with the first sub-groove 10421. The second sub-groove 10422 is arranged at an angle with the first groove 1041, and the second sub-groove 10422 communicates with the cabinet 40 of the air conditioner.

[0059] In some embodiments, when the main board 20 burns, since the second sub-slot 10422 is arranged at an angle with the first slot 1041, when the air flow enters the second sub-slot 10422 from the first slot 1041 through the first sub-slot 10421, the air path will bend, which can change the flow direction of the air flow, further increase the path length of the air flow during passing, and then increase the resistance when the air flow passes. Due to the increase in resistance, the flame will be hindered when following the air flow into the second sub-slot 10422, which can effectively reduce the possibility of the flame entering the second sub-slot 10422 and ensure the safety of the equipment in the air conditioner cabinet 40.

[0060] In some embodiments, the included angle between the second sub-slot 10422 and the first slot 1041 can be an acute angle, an obtuse angle or a right angle.

[0061] In some embodiments, in order to further prevent the flame from entering the air conditioner cabinet 40 along with the air flow, the connection part between the second sub-slot 10422 and the air conditioner cabinet 40 and the connection part between the first slot 1041 and the first sub-slot 10421 are located on the same side of the first sub-slot 10421.

[0062] Combined with Figure 6 , in some embodiments, when the main board 20 burns, since the connection part between the second sub-slot 10422 and the air conditioner cabinet 40 and the connection part between the first slot 1041 and the first sub-slot 10421 are located on the same side of the first sub-slot 10421, when the air flow enters the air conditioner cabinet 40 from the second sub-slot 10422, the air path will bend, which can change the flow direction of the air flow, further increase the path length of the air flow during passing, and then increase the resistance when the air flow passes. Due to the increase in resistance, the flame will be hindered when following the air flow into the air conditioner cabinet 40, which can effectively reduce the possibility of the flame entering the air conditioner cabinet 40 and ensure the safety of the equipment in the air conditioner cabinet 40.

[0063] Combined with Figure 7 , in some embodiments, to facilitate the connection between the second sub-slot 10422 and the air conditioner cabinet 40, a plurality of second heat dissipation holes 10423 are formed in the slot wall of the second sub-slot 10422, and the plurality of second heat dissipation holes 10423 communicate the second sub-slot 10422 and the air conditioner cabinet 40, wherein the connection part between the first slot 1041 and the first sub-slot 10421 and the plurality of second heat dissipation holes 10423 are located on the same side of the first sub-slot 10421.

[0064] In some embodiments, to have heat-generating components on the main board 20, along the thickness direction of the main board mounting box 103, at least a part of the projection of the heat-generating component 20 on the main board mounting box 103 overlaps with a plurality of second heat dissipation holes 10423, so that the heat-generating component is close to the second heat dissipation holes 10423, facilitating the transfer of heat radiation and ensuring the heat dissipation effect.

[0065] Combined with Figure 2 、 Figure 4 and Figure 9 In some embodiments, to facilitate the installation of the main board mounting box 103, the main board mounting box 103 has a positioning portion 106, and the positioning portion 106 can be embedded in the second groove 1042. When the main board mounting box 103 is to be installed in the electric control box 102, the positioning portion 106 can be embedded in the second groove 1042 to complete the preliminary positioning without complex adjustment and calibration steps, making the installation process of the main board mounting box 103 simple and fast. Moreover, it can reduce the error and uncertainty during the installation of the main board mounting box 103, enabling the main board mounting box 103 to be stably and accurately fixed at the predetermined position of the electric control box 102. At the same time, after the positioning portion 106 is completely embedded in the second groove 1042, the groove wall of the second groove 1042 can clamp and position the positioning portion 106, providing a firm support for the main board mounting box 103, preventing the main board mounting box 103 from loosening or displacing during use, and effectively reducing the risk of damage caused by vibration or impact, ensuring the stability of the installation of the main board mounting box 103.

[0066] In some embodiments, the second groove 1042 can not only allow the heat radiation of the main board 20 to enter the box body 40 of the air conditioner, but also cooperate with the positioning portion 106 to achieve positioning, realizing the "dual use of one groove" and reducing the cost.

[0067] In some embodiments, to further reduce the working temperature of the main board 20, the positioning portion 106 is provided with a heat conduction groove 107 communicating with the second groove 1042. Among them, the heat conduction groove 107 is located between the first surface 201 and the second groove 1042.

[0068] In some embodiments, when the main board 20 is working, the main board 20 generates heat radiation. Part of the heat radiation between the first surface 201 and the bottom surface enters the box body 40 of the air conditioner successively through the first heat dissipation holes 105, the first groove 1041 and the second groove 1042. Another part of the heat radiation can enter the box body 40 of the air conditioner successively through the heat conduction groove 107 and the second groove 1042, increasing the heat dissipation area of the first surface 201, enabling the heat radiation generated by the main board 20 to be effectively dissipated, so as to achieve sufficient heat dissipation of the first surface 201, further reducing the working temperature of the main board 20, improving the stability and service life of the main board 20, ensuring that the main board 20 can work normally, thereby improving the overall performance and efficiency of the air conditioner. Moreover, by allowing the heat radiation of the main board 20 to enter the box body 40 through the first heat dissipation channel 30, the risk of damage to the main board 20 due to overheating can be reduced, thus extending the service life of the main board 20. At the same time, it can reduce safety hazards such as fires caused by the high temperature of the main board 20, improving the user experience.

[0069] In some embodiments, to facilitate the airflow to enter the second groove 1042 from the heat conduction groove 107, the positioning portion 106 is spaced from the bottom of the second groove 1042 to prevent the heat conduction groove 107 from being blocked by the groove wall of the second groove 1042 and ensure smooth airflow.

[0070] In some embodiments, the heat conduction groove 107 is arranged at an angle with the second heat dissipation hole 10423. When the main board 20 burns, when the airflow enters the second heat dissipation hole 10423 from the heat conduction groove 107, the air path will bend, which can change the flow direction of the airflow, further increasing the path length of the airflow during the passing process, and then increasing the resistance when the airflow passes. Due to the increase in resistance, the flame will be hindered when following the airflow into the box body 40 of the air conditioner, effectively reducing the possibility of the flame entering the box body 40 of the air conditioner and ensuring the safety of the equipment in the box body 40 of the air conditioner.

[0071] Figure 5 For Figure 1 Schematic diagram of the air intake of the electronic control component in the middle. Combining Figure 2 And Figure 5 In some embodiments, to achieve heat dissipation of the second surface 202, the electronic control box 102 is provided with a first wiring hole 108 for air intake and a second wiring hole 109 for air outlet which are arranged at intervals. Both the first wiring hole 108 and the second wiring hole 109 communicate with the open end 101 and the box body 40 of the air conditioner.

[0072] In some embodiments, when the air conditioner is running, the fan assembly in the air conditioner case 40 is activated to allow air to flow in the case 40. Part of the air can enter the electrical control box 102 through the first wiring hole 108 and be blown toward the second surface 202 through the opening 101. After exchanging heat with the second surface 202, the air enters the case 40 through the second wiring hole 109, thereby effectively dissipating the heat generated by the mainboard 10 and reducing the possibility of heat accumulation at the mainboard 10, so as to achieve heat dissipation of the second surface 202, further reduce the operating temperature of the mainboard 10, further improve the stability and life of the mainboard 20, and improve the stability and performance of the air conditioner.

[0073] In some embodiments, the equipment inside the air conditioner case 40 can be electrically connected to the mainboard 20 via cables passing through the first wiring hole 108 or the second wiring hole 109 to achieve signal transmission. That is to say, the first wiring hole 108 can be used not only as a wiring hole, but also as an air inlet, realizing "two uses in one hole" and reducing costs. The second wiring hole 109 can be used not only as a wiring hole, but also as an air outlet, realizing "two uses in one hole" and reducing costs.

[0074] In some embodiments, in order to prevent flames from entering the air conditioner case 40 along with the air flow, the first wiring hole 108 and the second wiring hole 109 are staggered with the mainboard mounting box 103, so that there are no combustible materials at the first wiring hole 108 and the second wiring hole 109. When the mainboard 20 burns, flames will not enter the air conditioner case 40 through the first wiring hole 108 and / or the second wiring hole 109 along with the air flow, thereby ensuring the safety of the equipment in the air conditioner case 40.

[0075] Combination Figure 2 and Figure 5 In some embodiments, in order to ensure the heat dissipation effect of the second surface 202, the first wiring hole 108 and the second wiring hole 109 are set at an angle. When the air enters the opening 101 from the first wiring hole 108 and enters the second wiring hole 109 from the opening 101, the air flow path is not a straight line, but is bent, which can extend the air flow path, increase the contact area between the air and the second surface 202, and is conducive to the dissipation of heat and improve the heat dissipation efficiency. In addition, the resistance of air flow can be increased to ensure the contact time between the air and the second surface 202, which is further conducive to the dissipation of heat and improves the heat dissipation efficiency. Among them, the angle between the first wiring hole 108 and the second wiring hole 109 can be an acute angle, a right angle or an obtuse angle.

[0076] Combination Figure 2 and Figure 5, in some embodiments, the electronic control box 102 includes a box body 1022. A first wire routing hole 108 is provided at the top of the box body 1022, and a second wire routing hole 109 is provided at the side of the box body 1022, so that the first wire routing hole 108 and the second wire routing hole 109 are arranged at an angle. Among them, the end face of the box body 1022 facing the main board mounting box 103 is the bottom surface of the mounting structure 10.

[0077] Combined with Figure 2 and Figure 5 , in some embodiments, in order to further ensure the heat dissipation effect of the second surface 202, the electronic control box 102 is provided with an air inlet 1021 communicating the open end 101 and the box body 40 of the air conditioner. The air inlet 1021 and the first wire routing hole 108 are located on the same side of the electronic control box 102 and are spaced apart from each other.

[0078] In some embodiments, when the air conditioner is operating, the fan assembly in the box body 40 of the air conditioner operates to make the air flow in the box body 40. Part of the air can enter the electronic control box 102 through the air inlet 1021, and blow towards the second surface 202 through the open end 101. After exchanging heat with the second surface 202, it enters the box body 40 through the second wire routing hole 109, effectively dissipating the heat generated by the main board 10, reducing the possibility of heat accumulation at the main board 10, so as to achieve the heat dissipation of the second surface 202, increasing the air volume entering the electronic control box 102, further reducing the working temperature of the main board 10, further improving the stability and lifespan of the main board 20, and improving the stability and performance of the air conditioner.

[0079] Combined with Figure 12 , in some embodiments, the bottom of the side of the box body 1022 has a notch. When the box body 1022 is connected to the chassis 401 of the box body 40, the notch and the chassis 401 will form the air inlet 1021.

[0080] Figure 11 For Figure 1 the structural schematic diagram of the second heat dissipation channel of the electronic control component in. Combined with Figure 5 and Figure 11 , in some embodiments, in order to ensure that the air after exchanging heat with the main board 20 is fully discharged, the electronic control box 102 is provided with a second heat dissipation channel 50 communicating the open end 101 and the box body 40 of the air conditioner. The main board 20 is located between the second heat dissipation channel 50 and the second wire routing hole 109. Among them, the number of the second heat dissipation channels 50 can be one or more.

[0081] In some embodiments, after the air exchanges heat with the main board 20, it can sequentially enter the box body 40 of the air conditioner through the opening 101 and the second heat dissipation channel 50, enabling the air that has exchanged heat with the main board 20 to be smoothly discharged, increasing the air outlet area, reducing the residence time of the air that has exchanged heat with the main board 20 in the box body, improving the heat dissipation efficiency, further reducing the operating temperature of the main board 10, further enhancing the stability and lifespan of the main board 20, and improving the stability and performance of the air conditioner.

[0082] Combined with Figure 5 and Figure 11 , in some embodiments, to prevent the flame from entering the box body 40 of the air conditioner along with the air flow, the second heat dissipation channel 50 has a first air outlet 501 communicating with the opening 101 and a second air outlet 502 communicating with the box body 40 of the air conditioner, and the first air outlet 501 and the second air outlet 502 are arranged at an angle. Among them, the included angle between the first air outlet 501 and the second air outlet 502 can be an acute angle, a right angle, or an obtuse angle.

[0083] In some embodiments, the first air outlet 501 and the second air outlet 502 are arranged at an angle. When the main board 20 burns, when the air flow enters the second heat dissipation channel 50 from the first air outlet 501 and is discharged into the box body 40 of the air conditioner through the second air outlet 502, the air path will bend, which can change the direction of the air flow, further increasing the path length of the air flow during the passing process, and thus increasing the resistance when the air flow passes. Due to the increase in resistance, the flame will be hindered when following the air flow into the box body 40 of the air conditioner, effectively reducing the possibility of the flame entering the box body 40 of the air conditioner and ensuring the safety of the equipment in the box body 40 of the air conditioner.

[0084] Combined with Figure 5 and Figure 11 , in some embodiments, the opening direction of the first air outlet 501 is the same as the opening direction of the opening 101. When the main board 20 burns, when the air flow reaches the first air outlet 501 from the opening 101, the air path will bend, which can change the direction of the air flow, further increasing the path length of the air flow during the passing process, and thus increasing the resistance when the air flow passes. Due to the increase in resistance, the flame will be hindered when following the air flow into the box body 40 of the air conditioner, effectively reducing the possibility of the flame entering the box body 40 of the air conditioner and ensuring the safety of the equipment in the box body 40 of the air conditioner.
