[0067] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0068] Next, refer to the attached Figure 1-14 Describe the electric control box assembly 100 according to an embodiment of the present invention.

[0069] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 , the electric control box assembly 100 according to an embodiment of the present invention is used for the outdoor unit 1000 of an air conditioner. The electric control box assembly 100 includes: an electric control box 10, an electric control board 20, an electric control element 30, a heating element 40, and a bracket 50.

[0070] Specifically, a receiving cavity 13 and a first mounting opening 111 communicating with the receiving cavity 13 are defined within the electronic control box 10; the electronic control board 20 is arranged within the receiving cavity 13; the electronic control components 30 are provided on the electronic control board 20 and are located within the receiving cavity 13; the heating element 40 is arranged outside the receiving cavity 13, and one end of the heating element 40 (such as Figure 9 as shown, the upper end of the heating element 40) is located at the position of the first mounting opening 111 and is connected to the electronic control board 20 at the position of the first mounting opening 111; the bracket 50 is connected to the electronic control box 10, and the bracket 50 and the outer surface of the electronic control box 10 cooperate to define a heat dissipation flow channel 14 having an air inlet and an air outlet 151, and the heating element 40 is located within the heat dissipation flow channel 14.

[0071] The heating element 40 is arranged outside the receiving cavity 13. When the heating element 40 is operating, the heat generated by the heating element 40 will be dissipated to the outside of the electronic control box 10, and the heat will not be dissipated into the receiving cavity 13 of the electronic control box 10, thereby not affecting the heat dissipation within the receiving cavity 13.

[0072] For example, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9 shown, the first mounting hole penetrates through the bottom wall 1101 of the electronic control box 10 in the vertical direction, and the receiving cavity 13 communicates with the outside of the electronic control box 10 through the first mounting hole. The heating element 40 is arranged in the vertical direction, the upper end of the heating element 40 is connected to the electronic control board 20, and the lower end of the heating element 40 extends into the heat dissipation flow channel 14 from the first mounting hole. The heat dissipation flow channel 14 is provided between the bracket 50 and the electronic control box 10, the heat dissipation flow channel 14 is provided at the lower side of the rear side of the electronic control box 10, the heat dissipation flow channel 14 extends in the left-right direction, the right end of the heat dissipation flow channel 14 forms an air inlet, and the left end of the heat dissipation flow channel 14 forms an air outlet 151.

[0073] When the electronic control box assembly 100 is operating, the electronic control board 20 controls the operation of the heating element 40 and the electronic control components 30. When the heating element 40 is operating, it dissipates heat to the outside of the electronic control box 10. The air flow in the heat dissipation flow channel 14 flows along the heat dissipation flow channel 14 from the air inlet. When the air flow reaches the heating element 40, the air flow blows the heat dissipated by the heating element 40, causing the heat to flow along with the air flow to the air outlet 151, thereby reducing the temperature of the heating element 40.

[0074] For the electronic control box assembly 100 of the present invention, the heating element 40 is arranged outside the accommodation cavity 13. When the heating element 40 operates, the heat in the heating element 40 can be dissipated to the outside of the electronic control box 10. Compared with the prior art solution in which the heating element 40 is arranged inside the accommodation cavity 13 resulting in ineffective heat reduction, the electronic control box assembly 100 of this embodiment can dissipate the heat to the outside of the electronic control box 10 through the heat dissipation channel 14, enabling the heating element 40 to cool down quickly, thereby meeting the cooling requirement of the heating element 40 and preventing the heating element 40 from being damaged due to overheating. At the same time, the heat generated by the heating element 40 no longer transfers to the inside of the accommodation cavity 13, and the heat generated by the heating element 40 no longer transfers to the electronic control element 30, thus avoiding damage to the electronic control element 30 due to overheating and further increasing the service life of the electronic control element 30. Moreover, the temperature inside the accommodation cavity 13 is no longer affected by the heating element 40, which facilitates cooling inside the accommodation cavity 13 and further protects the electronic control element 30.

[0075] In addition, the bracket 50 and the electronic control box 10 cooperate to form the heat dissipation channel 14, eliminating the need to additionally provide the heat dissipation channel 14, thereby reducing the use of components and lowering the production cost. At the same time, the structure of the heat dissipation channel 14 is reasonably arranged, which can optimize the overall structure of the electronic control box assembly 100. Moreover, the heat dissipation channel 14 cools the heating element 40 separately, accelerating the heat dissipation of the heating element 40 and improving the heat dissipation efficiency, thus avoiding damage to the heating element 40 caused by excessive temperature generated by the heating element 40.

[0076] For the electronic control box assembly 100 according to the embodiment of the present invention, the heating element 40 is arranged outside the electronic control box 10, thereby meeting the cooling requirement of the heating element 40. At the same time, the structure of the heat dissipation channel 14 is reasonably arranged, which can optimize the overall structure of the electronic control box assembly 100 and also accelerate the heat dissipation of the heating element 40, improving the heat dissipation efficiency.

[0077] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 11 , the air inlet is formed on the bracket 50 and penetrates through the bracket 50 along the thickness direction of the bracket 50 (such as the front-back direction shown in Figure 11 ). Thus, the air flow can flow into the heat dissipation channel 14 from the air inlet, thereby cooling the heating element 40 in the heat dissipation channel 14.

[0078] Furthermore, the bracket 50 and the electronic control box 10 enclose a heat dissipation channel 14 with one end open, and the open side of the heat dissipation channel 14 is formed as an air inlet. Thus, it is further convenient for air to flow into the heat dissipation channel 14 from the air inlet, thereby ensuring the cooling rate of the heating element 40. At the same time, the air inlet formed on the open side of the heat dissipation channel 14 cooperates with the air inlet on the bracket 50, enabling multiple air inlets to communicate with the heat dissipation channel 14, thereby further ensuring the cooling efficiency of the heat dissipation channel 14 for the heating element 40.

[0079] For example, as Figure 2 , Figure 3 and Figure 11 shown, the bracket 50 is provided with an air inlet that penetrates the bracket 50 in the front-rear direction. The right end of the heat dissipation channel 14 is open to form an air inlet, and air can enter the heat dissipation channel 14 from the air inlet to cool the heating element 40.

[0080] According to some alternative embodiments of the present invention, referring to Figure 8 and Figure 12 , multiple air inlets are formed on the bracket 50. That is to say, two, three, four or more air inlets can be formed on the bracket 50, and the multiple air inlets are arranged at intervals. Thus, the multiple air inlets can increase the air intake volume of the heat dissipation channel 14, thereby improving the cooling efficiency of the heating element 40.

[0081] According to some alternative embodiments of the present invention, referring to Figure 3 and Figure 11 , a baffle 512 is provided along the circumference of at least part of the air inlets. That is to say, the baffle 512 can be provided along the circumference of some of the air inlets, or it can be provided along the circumference of all the air inlets. The baffle 512 extends along the circumferential direction of the air inlet. One end of the baffle 512 (such as Figure 11 the right end of the baffle 512 shown) is connected to the circumference of one side of the air inlet (such as Figure 11 the left side of the air inlet shown), and the other end (such as Figure 11 the left end of the baffle 512 shown) extends obliquely along the thickness direction of the bracket 50 (such as Figure 11 the front-rear direction shown) towards the circumference of the other side of the air inlet (such as Figure 11 the right side of the air inlet shown). Thus, the baffle 512 can guide the flow direction of the air flowing into the heat dissipation channel 14, enabling the air to flow to the heating element 40 in the heat dissipation channel 14. Therefore, the air can cool the heating element 40 after flowing into the heat dissipation channel 14 through the air inlet. At the same time, the baffle 512 can prevent objects such as rainwater, gravel, and paper scraps from entering the heat dissipation channel 14 from the air inlet, thereby preventing these objects from coming into contact with the heating element 40 in the heat dissipation channel 14, and further protecting the heating element 40.

[0082] According to some alternative embodiments of the present invention, referring toFigure 3 and Figure 11 The rib 512 is provided on one side of the bracket 50 facing the heat dissipation channel 14. Thus, compared with the solution where the rib 512 is arranged on the side facing away from the heat dissipation channel 14, arranging the rib 512 on the side facing the heat dissipation channel 14 can prevent damage when the electronic control box assembly 100 is assembled with other structures in the air conditioner outdoor unit 1000, thereby protecting the rib 512. At the same time, it can also reduce the overall volume of the electronic control box assembly 100 and reduce the space occupation.

[0083] For example, as shown in Figure 3 and Figure 11 , a rib 512 is provided along the perimeter of each air inlet. The rib 512 is arranged on the left perimeter of the air inlet. The left side of the rib 512 is connected to the bracket 50, and the right side of the rib 512 extends forward and to the right to form an arc-shaped rib 512. In this way, the air flow can flow from the defined space between the right perimeter of the air inlet and the right perimeter of the rib 512 to the heat dissipation channel 14.

[0084] According to some embodiments of the present invention, referring to Figure 3 and Figure 11 , the bracket 50 includes a first support plate 51 and a second support plate 52. The first support plate 51 extends along a first direction (such as the up-down direction shown in Figure 11 ), and the second support plate 52 extends along a second direction (such as the front-back direction shown in Figure 11 ). The first direction intersects with the second direction. One end of the first support plate 51 (such as the lower end of the first support plate 51 shown in Figure 11 ) is connected to one end of the second support plate 52 (such as the rear end of the second support plate 52 shown in Figure 11 ). The other end of the first support plate 51 (such as the upper end of the first support plate 51 shown in Figure 11 ) and the other end of the second support plate 52 (such as the front end of the second support plate 52 shown in Figure 11 ) are both connected to the electronic control box 10. The first support plate 51 and the second support plate 52 enclose a heat dissipation channel 14 extending along a third direction (such as the left-right direction shown in Figure 11 ), and the third direction is perpendicular to the first direction and the second direction.

[0085] In this way, one end of the first support plate 51 is connected to one end of the second support plate 52, making the bracket 50 a whole, thereby increasing the overall strength of the bracket 50 and avoiding damage to the support plates. Moreover, the other end of the first support plate 51 and the other end of the second support plate 52 can be fixedly connected to the electric control box 10, thereby increasing the connection strength between the bracket 50 and the electric control box 10 and preventing the support plates from separating from the electric control box 10 during the use of the electric control box assembly 100. At the same time, the first support plate 51, the second support plate 52 and the electric control box 10 cooperate to form a heat dissipation channel 14, eliminating the need to additionally provide the heat dissipation channel 14, thus reducing the use of components and lowering the production cost.

[0086] For example, as Figure 3 and Figure 11 shown, the first support plate 51 is a rectangular plate extending in the up and down direction, and the second support plate 52 is a rectangular plate extending in the front and back direction. The lower end of the first support plate 51 is connected to the rear end of the second support plate 52, so that the first support plate 51 and the second support plate 52 form an L-shaped support plate. The lower end at the rear side of the electric control box 10 is recessed upward. The upper end of the first support plate 51 is connected to the upper end of the electric control box 10, and the front end of the second support plate 52 is connected to the front end of the electric control box 10. When the bracket 50 and the electric control box 10 are assembled, the lower side of the first support plate 51 and the rear side of the second support plate 52 and the lower end at the rear side of the electric control box 10 define a heat dissipation channel 14 extending in the left and right direction. The right end of the heat dissipation channel 14 is open to form an air inlet.

[0087] According to some alternative embodiments of the present invention, referring to Figure 3 and Figure 11 , the number of air inlets is multiple, that is to say, the number of air inlets can be two, three or four or more. The multiple air inlets include a first air inlet 511, and the first air inlet 511 is formed on the first support plate 51. Thus, air can enter the heat dissipation channel 14 from the first air inlet 511 to cool the heating element 40, thereby accelerating the cooling speed of the heating element 40.

[0088] Furthermore, the multiple air inlets include a second air inlet 521, and the second air inlet 521 is formed on the second support plate 52. Thus, air can enter the heat dissipation channel 14 from the second air inlet 521 to cool the heating element 40, thereby accelerating the cooling speed of the heating element 40 again. At the same time, the first air inlet 511 and the second air inlet 521 cooperate to increase the air intake volume in the heat dissipation channel 14, thereby effectively preventing the heating element 40 from being damaged by high temperature. In addition, the arrangement directions of the first air inlet 511 and the second air inlet 521 are different, so that air can enter the heat dissipation channel 14 from multiple directions, thereby further enhancing the cooling speed of the heating element 40.

[0089] For example, as Figure 3 and Figure 11As shown, the first air inlet 511 penetrates the first support plate 51 in the front-rear direction, and the second air inlet 521 penetrates the second support plate 52 in the up-down direction. In this way, air can enter the heat dissipation channel 14 from the rear to the front through the first air inlet 511, and air can also enter the heat dissipation channel 14 from the bottom to the top through the second air inlet 521, thereby increasing the air intake of the heat dissipation channel 14.

[0090] According to some alternative embodiments of the present invention, referring to Figure 3 and Figure 11 , the number of the first air inlets 511 is multiple. That is to say, the number of the first air inlets 511 can be two, three, four or more. The multiple first air inlets 511 are arranged at intervals in the third direction (such as Figure 11 the left-right direction shown); the number of the second air inlets 521 is multiple. That is to say, the number of the second air inlets 521 can be two, three, four or more. The multiple second air inlets 521 are arranged at intervals in the third direction (such as Figure 11 the left-right direction shown). Thus, the multiple first air inlets 511 and the multiple second air inlets 521 can further increase the air intake of the heat dissipation channel 14, thereby ensuring the heat dissipation requirement of the heating element 40 and avoiding damage to the heating element 40 due to overheating.

[0091] For example, as shown in Figure 3 and Figure 11 , a plurality of first air inlets 511 are formed on the left side of the first support plate 51. The multiple first air inlets 511 are arranged at intervals in the left-right direction. The first air inlets 511 extend in the up-down direction and penetrate the first support plate 51 in the front-rear direction. A baffle 512 is provided on the periphery of the first air inlet 511. The second air inlet 521 is provided at the middle position of the second support plate 52 and is directly opposite to the first mounting opening 111 in the up-down direction. The multiple second air inlets 521 extend in the front-rear direction and are arranged at intervals in the left-right direction.

[0092] According to some embodiments of the present invention, referring to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the electric control box 10 includes: a box body 11 and a box cover 12. One side of the box body 11 in the first direction (such as Figure 5 the up-down direction shown) (such as Figure 5The upper side of the box body 11 shown is formed as an open mouth, and the box cover 12 covers the open mouth of the box body 11 and is detachably connected to the box cover 12. The first installation opening 111 is formed on the box body 11. Thus, the box body 11 and the box cover 12 cooperate to form a receiving cavity 13 inside the electric control box 10, so as to provide a layout space for the electric control board 20 and the electric control components 30. At the same time, the box body 11 and the box cover 12 are detachably connected, which is convenient for installing the electric control board 20 and the electric control components 30 in the receiving cavity 13, and is also convenient for overhauling the electric control board 20 and the electric control components 30. In addition, when the box body 11 or the box cover 12 is damaged, it is convenient for repairing and replacing the box body 11 or the box cover 12.

[0093] In addition, the first installation opening 111 is formed on the box body 11. When the heating element 40 is installed, one end of the heating element 40 can be fixed to the electric control board 20, and the other end of the heating element 40 extends out of the receiving cavity 13 through the first installation hole, so that the heating element 40 can be separated from the receiving cavity 13 on the premise of ensuring the normal operation of the electric control component 30, and further the heat dissipated by the heating element 40 can be discharged through the heat dissipation channel 14.

[0094] For example, as Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 shown, the box cover 12 is a rectangular plate, the box cover 12 is arranged on the upper side of the box body 11, the box body 11 includes a bottom wall 1101 and a peripheral wall 1102, the bottom wall 1101 and the peripheral wall 1102 of the box body 11 cooperate to form a receiving cavity 13 that is open on the upper side, a first installation opening 111 is formed at the rear side of the middle of the bottom wall 1101 of the box body 11, and the first installation opening 111 penetrates the bottom wall 1101 of the box body 11 in the up and down direction. Three third card holes 1182 are provided on the outer surface of the peripheral wall 1102 of the box body 11, and three third buckles 122 are provided on the lower surface of the box cover 12. When the box cover 12 and the box body 11 are cooperatively installed, the third buckles 122 are snapped into the corresponding third card holes 1182 to realize the detachable connection between the box cover 12 and the box body 11.

[0095] According to some alternative embodiments of the present invention, referring to Figure 4 、 Figure 5 Figure 6 and Figure 11 , the air inlet is formed on the bracket 50 and penetrates the bracket 50 in the thickness direction of the bracket 50. The first installation opening 111 has a first edge 1111 extending in the first direction (such as the up and down direction shown in Figure 5 ), and the first edge 1111 is located on the side of the first installation opening 111 facing the air inlet (such as Figure 5at the rear side of the first mounting opening 111 shown, a baffle portion 112 is provided on the box body 11, and the baffle portion 112 is arranged on the side of the first edge 1111 facing the air inlet (such as Figure 5 at the rear side of the first edge 1111 shown) and extends in the depth direction of the first mounting opening 111 (such as Figure 5 the up and down direction of the first mounting opening 111 shown) away from the box cover 12, and the baffle portion 112 extends in the first direction and is formed with a communication hole 1122 communicating between the air inlet and the heating element 40.

[0096] In this way, the air flow can flow into the first mounting opening 111 through the communication hole 1122, so as to cool the heating element 40 in the first mounting opening 111, ensure the ventilation and heat dissipation requirements of the heating element 40. At the same time, the heating element 40 needs to maintain a dry environment during operation, and the baffle portion 112 can prevent liquids such as rainwater from directly flowing into the heating element 40 through the communication hole 1122. Thus, the baffle portion 112 can provide protection for the heating element 40 and prevent the heating element 40 from being damaged after contacting with liquids such as rainwater.

[0097] For example, as Figure 5 and Figure 6 shown, the rear side of the first mounting opening 111 is formed as the first edge 1111, the baffle portion 112 is arranged at the rear side of the first edge 1111, and the upper end of the baffle portion 112 is connected to the first edge 1111. The baffle portion 112 extends in the up and down direction, and the baffle portion 112 defines a communication hole 1122 extending in the up and down direction.

[0098] According to some alternative embodiments of the present invention, referring to Figure 5 and Figure 6 , the baffle portion 112 includes a plurality of stop baffles 1121. That is to say, the baffle portion 112 may include two, three or four or more stop baffles 1121. The plurality of stop baffles 1121 are arranged at intervals in the third direction (such as Figure 5 the left and right direction shown), and the communication hole 1122 is defined by the cooperation between two adjacent stop baffles 1121. Thus, the plurality of stop baffles 1121 can define a plurality of communication holes 1122, so as to ensure the air intake volume in the first mounting opening 111. The more the air intake volume is, the faster the heat dissipation efficiency of the heating element 40 is, and thus the heat dissipation requirements of the heating element 40 can be met. At the same time, the plurality of stop baffles 1121 can prevent liquids such as rainwater from entering the first mounting opening 111 through the communication hole 1122 and contacting the heating element 40, so as to increase the protection of the stop baffles 1121 for the heating element 40.

[0099] According to some alternative embodiments of the present invention, referring to Figure 5 and Figure 6, the baffle 1121 includes: a first plate segment 11211, a second plate segment 11212, and a third plate segment 11213. The first plate segment 11211 extends along the third direction (such as the left - right direction shown in Figure 6 ), one end of the second plate segment 11212 (such as the left end of the second plate segment 11212 shown in Figure 6 ) is connected to one end of the first plate segment 11211 in the third direction (such as the right end of the first plate segment 11211 shown in Figure 6 ), and the other end (such as the right end of the second plate segment 11212 shown in Figure 6 ) extends obliquely away from the first plate segment 11211 along the third direction and towards the air inlet; one end of the third plate segment 11213 (such as the left end of the third plate segment 11213 shown in Figure 6 ) is connected to one end of the first plate segment 11211, and the other end (such as the right end of the third plate segment 11213 shown in Figure 6 ) extends obliquely away from the first plate segment 11211 along the third direction and towards the first edge 1111.

[0100] Thus, the first plate segment 11211 can block rainwater from flowing into the heating element 40 through the communication hole 1122, thereby protecting the heating element 40. The second plate segment 11212 and the third plate segment 11213 can cooperate with the first plate segment 11211 of the adjacent baffle 1121 to form the communication hole 1122, so that air can conveniently flow from the communication hole 1122 to the heating element 40 to meet the heat dissipation requirements of the heating element 40. At the same time, the second plate segment 11212 and the third plate segment 11213 extend obliquely. When the air flows through the communication hole 1122, the second plate segment 11212 and the third plate segment 11213 can block liquids such as rainwater carried in the air flow, thereby further protecting the heating element 40.

[0101] For example, as shown in Figure 5 and Figure 6 , the first plate segment 11211 is in the shape of a plate extending along the left - right direction. The right end of the second plate segment 11212 is connected to the left end of the first plate segment 11211. The left end of the second plate segment 11212 extends obliquely from right - front to left - rear. The right end of the third plate segment 11213 is connected to the left end of the first plate segment 11211. The left end of the third plate segment 11213 extends obliquely from right - rear to left - front. In this way, the first plate segment 11211, the second plate segment 11212, and the third plate segment 11213 form a Y - shaped baffle.

[0102] Furthermore, as shown in Figure 5 and Figure 6As shown, affected by the installation position of the box body 11 of the electric control box 10, the angles of the second plate segment 11212 and the third plate segment 11213, the spacing and the number between the connected stop baffles 1121 can be adjusted according to actual needs. At the same time, for better ventilation, the edges of the stop baffles 1121 are rounded, which is more conducive to the air flow flowing from the communication holes 1122 to the heating element 40.

[0103] According to some embodiments of the present invention, referring to Figure 5 , Figure 7 and Figure 8 , a first sealing groove 121 is provided on the peripheral edge of the box cover 12. The first sealing groove 121 extends circumferentially along the box cover 12 to form a ring shape. One end of the box body 11 facing the box cover 12 (such as Figure 5 the upper end of the box body 11 shown) has an edge that fits into the first sealing groove 121. Thus, the edge of one end of the box body 11 extends into the first sealing groove 121 to seal the connection between the box body 11 and the box cover 12, which can ensure the tightness of the accommodation cavity 13. Therefore, it can not only prevent liquids such as rainwater from entering the accommodation cavity 13, but also prevent the heat dissipated by the heating element 40 from dissipating to the accommodation cavity 13 from the connection between the box body 11 and the box cover 12.

[0104] For example, as Figure 5 , Figure 7 and Figure 8 shown, a ring-shaped first sealing groove 121 is provided on the lower peripheral edge of the box cover 12, and the upper edge of the box cover 12 can extend into the first sealing groove 121, so as to realize the sealing between the upper edge of the box cover 12 and the box body 11.

[0105] According to some alternative embodiments of the present invention, referring to Figure 2 , Figure 5 and Figure 12 , a through opening 113 is formed on the peripheral wall 1102 of the box body 11, and the through opening 113 penetrates the edge of one side of the open opening (such as Figure 5 the front side of the open opening shown). The electric control box 10 further includes: a cover plate 60, and the cover plate 60 is connected to the box body 11 and the box cover 12 and covers the through opening 113. Thus, the cover plate 60 can cover the through opening 113, so that the box body 11, the box cover 12 and the cover plate 60 can form a sealed electric control box assembly 100, which can provide better protection for the electric control elements 30 and the electric control board 20 in the accommodation cavity 13.

[0106] For example, as Figure 2 , Figure 5 and Figure 12As shown, the front side peripheral wall 1102 of the box body 11 is penetrated in the vertical direction through the opening 113. The cover plate 60 is a rectangular plate extending in the vertical direction. The cover plate 60 seals the opening 113, and the upper end of the cover plate 60 is hermetically connected to the box cover 12, and the lower end of the cover plate 60 is hermetically connected to the box body 11, so that a sealed electronic control box 10 can be formed.

[0107] According to some alternative embodiments of the present invention, referring to Figure 2 , Figure 5 and Figure 12 , a second sealing groove 1141 is formed along the peripheral edge of the opening 113. One end of the cover plate 60 facing the box cover 12 (such as Figure 12 the upper end of the cover plate 60 shown) is fitted into the first sealing groove 121, and one end of the cover plate 60 facing the box body 11 (such as Figure 12 the lower end of the cover plate 60 shown) is fitted into the second sealing groove 1141. Thus, both ends of the cover plate 60 are respectively fitted with the first sealing groove 121 and the second sealing groove 1141. When the cover plate 60 is fitted with the box body 11 and the box cover 12, the sealing performance of the cover plate 60, the box body 11 and the box cover 12 can be further improved, so that liquids such as rainwater can be effectively prevented from flowing into the accommodation cavity 13.

[0108] For example, as Figure 2 , Figure 5 and Figure 12 shown, the upper end edge of the cover plate 60 extends into the first sealing groove 121 of the box cover 12 to be connected to the box cover 12, and the lower end edge of the cover plate 60 extends into the second sealing groove 1141 of the box body 11 to be connected to the box body 11, so that a sealed connection can be achieved between the cover plate 60, the box cover 12 and the box body 11.

[0109] Furthermore, as Figure 2 , Figure 5 and Figure 12 shown, a fourth locking hole 62 is formed at the lower end of the cover plate 60, and a fourth locking buckle 1183 corresponding to the fourth locking hole 62 is formed on the lower side of the bottom wall 1101 of the box body 11. When the cover plate 60 is connected to the box body 11, the fourth locking buckle 1183 is snapped into the fourth locking hole 62, so as to realize the fixed connection between the cover plate 60 and the box body 11. Moreover, a first screw hole 119 is formed on the peripheral wall 1102 of the box body 11, and a second screw hole 61 is further formed on the cover plate 60. A screw can sequentially pass through the second screw hole 61 and the first screw hole 119 to fixedly connect the cover plate 60 and the box body 11. In addition, a kneading portion is formed on the cover plate 60, which can facilitate the processing of the cover plate 60.

[0110] According to some alternative embodiments of the present invention, referring to Figure 5 and Figure 8, the depth of the first sealing groove 121 is greater than or equal to 3 mm, and the depth of the second sealing groove 1141 is greater than or equal to 3 mm. Thus, one end of the cover plate 60 can be firmly inserted into the first sealing groove 121, and the other end of the cover plate 60 can be firmly inserted into the second sealing groove 1141, so that the sealing performance of the connection between the cover plate 60 and the first sealing groove 121 and the second sealing groove 1141 can be further ensured.

[0111] For example, Figure 5 and Figure 8 As shown, the depth of the first sealing groove 121 may be 3 mm, 4 mm, 5 mm, 6 mm or 7 mm, and the depth of the second sealing groove 1141 may be 3 mm, 4 mm, 5 mm, 6 mm or 7 mm.

[0112] According to some embodiments of the present invention, referring to Figure 2 , Figure 4 and Figure 5 , through the side of the opening 113 away from the cover 12 (such as Figure 4 A first wire groove 115 is formed on the edge of the through opening 113 shown in the figure. A first elastic member 81 is inserted into the first wire groove 115. The first elastic member 81 has a first wire hole 811 for inserting a wire harness. The side of the cover plate 60 facing the first wire groove 115 (as shown in the figure) is provided with a first elastic member 81. Figure 2 The lower side edge of the cover plate 60 shown is interference fit with the first elastic member 81.

[0113] Thus, the first wire groove 115 can provide an installation position for the first elastic member 81, so that the installation of the first elastic member 81 can be facilitated. The first wire hole 811 is provided in the first elastic member 81, and the first wire hole 811 can facilitate the wire harness of the electric control board 20 to extend from the first wire hole 811, so as to facilitate the connection between the electric control board 20 and other components. At the same time, the first elastic member 81 can prevent the wire harness from being damaged when passing through the first wire hole 811, so as to protect the wire harness. In addition, the cover plate 60 and the first elastic member 81 are interference-fitted, so as to prevent the first elastic member 81 from detaching from the first wire groove 115.

[0114] For example, Figure 2 , Figure 4 and Figure 5As shown, a first wire-passing groove 115 is formed on the lower side of the opening 113 and passes through the bottom wall 1101 of the box body 11 in the up-down direction. A first elastic member 81 extending in the up-down direction is provided inside the first wire-passing groove 115. A first wire hole 811 is defined inside the first elastic member 81, and the wire harness of the electric control board 20 can pass through the first wire hole 811. Preferably, three first wire-passing grooves 115 are provided, and the three first wire-passing grooves 115 are arranged at intervals in the left-right direction, so that the electric control box 10 can be conveniently connected to the outside through the first wire hole 811. The first elastic member 81 is elastic, so that the first elastic member 81 can be pressed into the first wire-passing groove 115.

[0115] According to some embodiments of the present invention, referring to Figure 2 , Figure 3 Figure 4 and Figure 5 , one side of the box body 11 (such as Figure 3 The right side of the box body 11 shown in the figure is formed with a Figure 3 The second wire groove 116 (in the vertical direction shown in the figure) passes through the box body 11, and a second elastic member 82 is inserted into the second wire groove 116. The second elastic member 82 has a second wire hole 821 for inserting the wire harness. Therefore, the second wire groove 116 can provide an installation position for the second elastic member 82, so that the installation of the second elastic member 82 can be facilitated. The second elastic member 82 is provided with a second wire hole 821. The second wire hole 821 can facilitate the wire harness of the electric control board 20 to extend from the second wire hole 821, so as to facilitate the connection between the electric control board 20 and other components. At the same time, the second elastic member 82 can prevent the wire harness from being damaged when passing through the second wire hole 821, so as to protect the wire harness. In addition, this arrangement can improve the wiring method without the need to add additional adapter wires, thereby saving assembly time and improving the assembly efficiency of the electric control box assembly 100.

[0116] For example, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a second wire passing groove 116 is formed on the right side edge of the box body 11 and passes through the bottom wall 1101 of the box body 11 in the up-down direction. A second elastic member 82 extending in the front-to-back direction is provided inside the second wire passing groove 116. A second wire hole 821 is defined in the second elastic member 82. The wiring harness of the electric control board 20 can pass through the second wire hole 821, thereby further facilitating the connection of the electric control box 10 with the outside world through the second wire hole 821. The second elastic member 82 is elastic, so that the second elastic member can be pressed into the second wire passing groove 116.

[0117] According to some embodiments of the present invention, referring to Figure 2 , Figure 3 and Figure 5, a bump 1161 is formed on the bottom wall 1101 of the second wire groove 116, and the bump 1161 abuts against the second elastic member 82. Thus, the bump 1161 can limit the movement of the second elastic member 82, thereby effectively preventing the second elastic member 82 from detaching from the second wire groove 116. In addition, this setting form can improve the wire routing method without adding extra jumpers, thereby saving assembly time and improving the assembly efficiency of the electronic control box assembly 100.

[0118] For example, as Figure 2 , Figure 3 and Figure 5 shown, the bump 1161 extends upward on the bottom wall 1101 of the second wire groove 116, the second elastic member 82 is arranged in the second wire groove 116 and is located above the bump 1161. When the box cover 12 is engaged with the box body 11, the box cover 12 abuts against the upper end of the second elastic member 82, and the bump 1161 abuts against the lower end of the second elastic member 82, thereby stably fixing the second elastic member 82 in the second wire groove 116 and effectively preventing the second elastic member 82 from detaching from the second wire groove 116.

[0119] According to some embodiments of the present invention, referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the electronic control box assembly 100 may further include: a heat dissipation member 70, the heat dissipation member 70 is arranged outside the accommodation cavity 13, the box body 11 is formed with a second installation opening 117 communicating with the accommodation cavity 13, the first installation opening 111 and the second installation opening 117 are arranged at intervals, and one end of the heat dissipation member 70 (such as Figure 4 shown as the upper end of the heat dissipation member 70) is connected to the periphery of the second installation opening 117, and the heat dissipation member 70 is used for dissipating heat from the electronic control board 20. Thus, the second installation opening 117 can provide a layout space for the heat dissipation member 70, thereby facilitating the layout of the heat dissipation member 70. At the same time, the heat dissipation member 70 can cool the electronic control board 20, thereby preventing the electronic control board 20 from being damaged due to overheating.

[0120] For example, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a rectangular second installation opening 117 is provided on the left side of the first installation opening 111, and the second installation opening 117 penetrates through the box body 11 in the up and down direction. When the heat dissipation member 70 is installed, the upper end of the heat dissipation member 70 is fixedly connected to the electronic control board 20, and the lower end of the heat dissipation member 70 extends out of the second installation opening 117 to the outside of the accommodation cavity 13.

[0121] According to some alternative embodiments of the present invention, referring to Figure 3 , Figure 4 and Figure 5, the air outlet 151 is arranged facing the heat dissipation member 70. Thus, the heat in the heat dissipation channel 14 can flow to the heat dissipation member 70 through the air outlet 151, so that the heat dissipation member 70 can dissipate the heat flowing out of the air outlet 151.

[0122] According to some alternative embodiments of the present invention, referring to Figure 3 , Figure 4 and Figure 6 , the electronic control box 10 further includes: a wind guide plate 15, the wind guide plate 15 is arranged outside the accommodation cavity 13 and located between the first installation opening 111 and the second installation opening 117, and the wind guide plate 15 and the outer surface of the box body 11 cooperate to define the air outlet 151. Thus, the wind guide plate 15 can guide the flow direction of the air flow in the heat dissipation channel 14, so that the air flow in the heat dissipation channel 14 can be guided to the heat dissipation member 70, thereby cooling the heating element 40 in the heat dissipation channel 14. At the same time, the wind guide plate 15 and the outer surface of the box body 11 define the air outlet 151, and there is no need to additionally provide an air outlet 151, so that the processing steps can be reduced and the production cost can be lowered.

[0123] For example, as Figure 3 , Figure 4 and Figure 6 shown, the heights of the first installation opening 111 and the second installation opening 117 of the box body 11 in the up-down direction are different, the second installation opening 117 is arranged above the first installation opening 111 and on the left side of the first installation opening 111, and the wind guide plate 15 is vertically arranged and arranged between the first installation opening 111 and the second installation opening 117.

[0124] When the air flow flows, the air flow can enter the heat dissipation channel 14 from the first air inlet 511 and the second air inlet 521, and then the air flow flows to the heating element 40 to take away the heat dissipated by the heating element 40, and then the air flow flows along the heat dissipation channel 14 to the air outlet 151, and then the air flow flows to the heat dissipation member 70 under the guidance of the wind guide plate 15, and the heat dissipation member 70 absorbs the heat in the air flow to complete the cooling of the heating element 40.

[0125] According to some alternative embodiments of the present invention, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 , in the direction from the electronic control board 20 towards the heating element 40, the wind guide plate 15 extends obliquely towards the side where the heating element 40 is located (such as Figure 5 the right side of the wind guide plate 15 shown) and extends to be connected to the bracket 50, and the end of the wind guide plate 15 far from the bracket 50 (such as Figure 5The rear end of the air deflector 15 shown) defines an air outlet 151 between the air deflector 15 and the box body 11. Thus, the air deflector 15 is connected to the bracket 50, which can facilitate the formation of a closed structure between the bracket 50 and the box body 11, thereby ensuring that the electronic control box assembly 100 is formed into a closed structure, which can protect the electronic control board 20 and the electronic control components 30 in the accommodation cavity 13. At the same time, the air deflector 15 extends obliquely, so that the air flow can be guided to flow along the inclined direction of the air deflector 15 to the heat dissipation member 70, and then the heat dissipation member 70 can be used to cool the heating element 40 in the heat dissipation channel 14.

[0126] For example, as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the air deflector 15 extends along the front-rear direction. The front end of the air deflector 15 is connected to the bracket 50. The rear end of the air deflector 15 defines the air outlet 151. The air deflector 15 is an arc-shaped plate that extends obliquely from the lower right to the upper left. The lower end of the air deflector 15 is connected to the bottom wall 1101 of the box body 11, and the upper end of the air deflector 15 is connected to the edge of the second installation opening 117.

[0127] According to some embodiments of the present invention, referring to Figure 3 and Figure 11 , the bracket 50 is further formed with a ventilation opening 522 that penetrates the bracket 50 in the thickness direction (such as Figure 11 shown in the up-down direction). The ventilation opening 522 is located on the side of the heat dissipation member 70 facing the heating element 40 (such as Figure 11 shown on the right side of the heat dissipation member 70). The ventilation opening 522 communicates with the heat dissipation member 70. Thus, the air flow can flow from the ventilation opening 522 to the heat dissipation member 70, and the air flow can cool the heat dissipation member 70, thereby avoiding damage to the heat dissipation member 70 due to excessive temperature and ensuring the cooling function of the heat dissipation member 70.

[0128] For example, as Figure 3 and Figure 11 shown, a ventilation hole is formed in the second support plate 52 of the bracket 50 that penetrates the second support plate 52 in the up-down direction. The ventilation opening 522 extends along the front-rear direction, and the ventilation hole is provided on the left side of the second air inlet 521. When the air wheel 300 of the indoor unit of the air conditioner rotates, the air wheel 300 drives the air flow to flow from the ventilation opening 522 to the heat dissipation member 70, thereby cooling the heat dissipation member 70.

[0129] According to some embodiments of the present invention, referring to Figure 3 , Figure 4 , Figure 5 and Figure 9 , the heat dissipation member 70 includes: a heat dissipation main body 71 and a support 72. The heat dissipation main body 71 is disposed on the support 72. A support edge 721 that extends along the circumference of the support 72 is formed on the support 72. One end of the support 72 (such as Figure 9The upper end of the support 72 shown in the figure passes through the second installation opening 117 and is connected to the inner wall of the accommodating cavity 13, and the supporting edge 721 abuts against the peripheral edge of the second installation opening 117. Thus, the support 72 can provide a fixed position for the heat sink 70, thereby facilitating the fixing of the heat sink 70 and the electric control board 20. At the same time, when the heat sink 70 is installed in the second installation opening 117, the supporting edge 721 can abut against the inner wall of the accommodating cavity 13, thereby preventing the heat sink 70 from falling from the second installation opening 117.

[0130] For example, Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, the upper end of the support 72 is fixed to the electric control board 20, the lower end of the support 72 is fixed to the upper end of the heat sink 70, the front side of the support 72 is provided with a support edge 721 extending forward, and the rear side of the support 72 is provided with a support edge 721 extending backward. The support edge 721 can abut against the inner wall of the installation cavity, thereby preventing the heat sink 70 from falling from the second installation port 117.

[0131] Furthermore, if Figure 5 and Figure 9 As shown, the peripheral edge of the support 72 is provided with a sealing edge 722, and the sealing edge 722 can abut against the support 72 and the inner wall of the accommodating cavity 13, so that the connection position between the support 72 and the inner wall of the accommodating cavity 13 can be sealed, thereby further improving the sealing performance of the electric control box assembly 100. In addition, the heating element 40 is arranged in the heat dissipation channel 14, which can accelerate the cooling of the heating element 40, so that there is no need to additionally set up a large-volume high-power cooling heat sink 70, thereby reducing the production cost and reducing the volume of the heat sink 70.

[0132] According to some embodiments of the present invention, referring to Figure 3 , Figure 4 , Figure 5 and Figure 9 The heating element 40 includes: a base 41, an element body 42 and a panel 43. Specifically, the base 41 is connected to the electric control board 20; the element body 42 is arranged on the base 41; the panel 43 extends in a ring shape along the circumference of the heating element 40, and the panel 43 is connected to the base 41 and is located on the side of the base 41 away from the electric control board 20 (such as Figure 9 As shown in the figure, the base 41 can provide a mounting position for the component body 42, so that the arrangement of the component body 42 can be facilitated. The enclosure 43 is connected to the base 41 and is annular, so that the enclosure 43 can enclose the component body 42 in the enclosure 43, so that the component body 42 can be isolated from the accommodating cavity 13.

[0133] For example, Figure 3 , Figure 4 , Figure 5and Figure 9 As shown, the base 41 is rectangular and is provided on the lower side of the electronic control board 20. The element body 42 extends in the vertical direction. The upper end of the element body 42 is fixedly connected to the base 41. The surrounding plate 43 is arranged in a rectangular ring and extends in the vertical direction. The upper end of the surrounding plate 43 is connected to the base 41. In this way, the surrounding plate 43 encloses the element body 42 inside the surrounding plate 43. When the heating element 40 is installed in the first installation opening 111, the surrounding plate 43 can abut against the periphery of the first installation opening 111, so as to isolate the element body 42 from the accommodation cavity 13.

[0134] Furthermore, as Figure 9 shown, the electronic control element 30 includes: a capacitor 31, an inductor 32, and a power interface 33. The capacitor 31, the inductor 32, and the power interface 33 are all fixed on the electronic control board 20. Thus, the capacitor 31, the inductor 32, and the power interface 33 all adopt miniaturized devices, so as to reduce the volume of the electronic control element 30 and the electronic control board 20, and further facilitate the sealing of the electronic control box assembly 100. At the same time, the use of miniaturized capacitor 31, inductor 32, and power interface 33 can reduce the use of materials, thereby reducing the production cost and being beneficial to improving the product competitiveness.

[0135] According to some embodiments of the present invention, referring to Figure 9 , one of the surrounding plate 43 and the base 41 is provided with a first buckle 411 and the other is provided with a first card hole 431. That is to say, it can be that the surrounding plate 43 is provided with the first buckle 411 and the base 41 is provided with the first card hole 431, or it can be that the base 41 is provided with the first buckle 411 and the surrounding plate 43 is provided with the first card hole 431. The first buckle 411 is fitted into the first card hole 431 to connect the surrounding plate 43 and the base 41 in a snap connection. Thus, the first buckle 411 and the first buckle 411 cooperate, so as to fixedly connect the surrounding plate 43 and the base 41, and effectively prevent the surrounding plate 43 from detaching from the base 41.

[0136] For example, as Figure 9 shown, the surrounding plate 43 is provided with the first card hole 431, and the base 41 is provided with the first buckle 411. When the surrounding plate 43 and the base 41 are fitted, the first buckle 411 of the base 41 is snapped into the first card hole 431 of the surrounding plate 43 to realize the fixation of the surrounding plate 43 and the base 41.

[0137] Furthermore, a plurality of first card holes 431 are arranged at intervals in the circumferential direction of the surrounding plate 43, and the first buckles 411 on the base 41 correspond to the first card holes 431 of the surrounding plate 43 one by one. In this way, the cooperation of the plurality of first card holes 431 and the plurality of first buckles 411 can increase the fixing strength of the surrounding plate 43 and the base 41, so as to effectively prevent the surrounding plate 43 from detaching from the base 41.

[0138] According to some embodiments of the present invention, referring toFigure 5 A convex edge 1112 extending towards the electronic control board 20 is formed along the periphery of the first mounting opening 111. The convex edge 1112 extends circumferentially along the first mounting opening 111 to form a ring, and the convex edge 1112 is in sealing contact with the surrounding plate 43. Thus, the convex edge 1112 can further increase the sealing performance at the contact portion between the first mounting opening 111 and the surrounding plate 43, and further ensure the sealing performance of the electronic control box assembly 100.

[0139] For example, as Figure 5 shown, a convex edge 1112 extending upward is formed along the periphery of the first mounting opening 111. The convex edge 1112 extends into a rectangular ring. When the surrounding enclosure is in contact with the periphery of the first mounting opening 111, the convex edge 1112 can block the gap between the periphery of the first mounting opening 111 and the lower end of the surrounding enclosure, thereby ensuring the sealing performance of the electronic control box assembly 100.

[0140] According to some embodiments of the present invention, referring to Figure 3 、 Figure 5 and Figure 11 , a second buckle 1181 is provided on one of the bracket 50 and the electronic control box 10, and a second card hole 54 is provided on the other. That is to say, the second buckle 1181 can be provided on the bracket 50 and the second card hole 54 can be provided on the electronic control box 10, or the second buckle 1181 can be provided on the electronic control box 10 and the second card hole 54 can be provided on the bracket 50. The second buckle 1181 is fitted into the second card hole 54 to connect the bracket 50 and the electronic control box 10 in a snap connection. Thus, the second buckle 1181 and the second buckle 1181 cooperate to fixedly connect the bracket 50 and the electronic control box 10, effectively preventing the bracket 50 from separating from the electronic control box 10.

[0141] For example, as Figure 3 、 Figure 5 and Figure 11 shown, the second card hole 54 is provided on the bracket 50, and the second buckle 1181 is provided on the electronic control box 10. When the bracket 50 and the electronic control box 10 are fitted, the second buckle 1181 of the electronic control box 10 is snapped into the second card hole 54 of the bracket 50 to realize the fixation of the bracket 50 and the electronic control box 10.

[0142] Furthermore, a plurality of second card holes 54 are arranged at intervals in the circumferential direction of the bracket 50, and the second buckles 1181 on the electronic control box 10 correspond to the second card holes 54 of the bracket 50 one by one. In this way, the cooperation of the plurality of second card holes 54 and the plurality of second buckles 1181 can increase the fixing strength of the bracket 50 and the electronic control box 10, thereby effectively preventing the bracket 50 from separating from the electronic control box 10.

The air flow can enter the heat dissipation channel 14 from the air inlet at the rear side of the heat dissipation channel 14, the first air inlet 511 and the third air inlet 513 of the first support plate 51, and the second air inlet 521 on the second support plate 52. The air flow flows through the heat dissipation channel 14 to the element body 42 to take away the heat dissipated by the element body 42. Then the air flow flows along the heat dissipation channel 14 to the air outlet 151, and then the air flow flows to the heat dissipation part 70 under the guidance of the air deflector 15. The heat dissipation part 70 absorbs the heat in the air flow, thereby realizing the cooling of the element body 42. At the same time, the electronic control board 20 controls the impeller 300 to rotate, and the rotation of the impeller 300 generates an air flow. The air flow can flow from the ventilation opening 522 to the heat dissipation part 70, so as to cool the heat dissipation part 70.
