[0048] The electric control box 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, the electric control box 10 according to an embodiment of the present invention includes a box body 1 , a first circuit board 2 , a second circuit board 3 , a first cover plate 4 and a second cover plate 5 .

[0050] Specifically, if Figure 1 and Figure 5 As shown, the box body 1 has a first direction (such as Figure 1 The first accommodating cavity 11 and the second accommodating cavity 12 are arranged in a spaced manner in the first direction (as shown in FIG), so that the layout of the components inside the electric control box 10 is more compact, more functions can be realized in a limited space, thereby improving the assembly density and reducing the overall volume of the electric control box 10. Figure 1 and Figure 6 As shown, the first accommodating cavity 11 is opened on one side away from the second accommodating cavity 12 to form a first opening 111. The second accommodating cavity 12 is opened along the second direction (eg Figure 1 One end of the housing (as shown in the second direction) is opened to form a second opening 121, and the first opening 111 and the second opening 121 are spaced apart, so that only the first opening 111 is opened when inspecting the components in the first housing cavity 11, and only the second opening 121 is opened when inspecting the components in the second housing cavity 12. In addition, electrical isolation between the first housing cavity 11 and the second housing cavity 12 can be achieved, avoiding mutual interference between the components in the first housing cavity 11 and the components in the second housing cavity 12, and the first direction is perpendicular to the second direction.

[0051] Furthermore, if Figure 1 、 Figure 2 and Figure 4 As shown, the first circuit board 2 is arranged in the first accommodating cavity 11, and the second circuit board 3 is arranged in the second accommodating cavity 12, so that only the first opening 111 is opened when the first circuit board 2 is inspected, and only the second opening 121 is opened when the second circuit board 3 is inspected, and electrical isolation of the first circuit board 2 and the second circuit board 3 can be achieved to avoid mutual interference between the first circuit board 2 and the second circuit board 3.

[0052] Furthermore, if Figure 1 and Figure 3 As shown, the first cover plate 4 is provided at the first opening 111 to block the first opening 111. The first cover plate 4 can effectively shield external electromagnetic interference, reduce the possibility of electromagnetic pulses coupling into the first accommodating cavity 11, and thus improve the electromagnetic compatibility of the first circuit board 2. It can achieve a seal on the first accommodating cavity 11, effectively preventing the intrusion of external environmental factors such as moisture and dust, and protecting the first circuit board 2 inside the first accommodating cavity 11 from damage. The second cover plate 5 is provided at the second opening 121 to block the second opening 121. The second cover plate 5 can effectively shield external electromagnetic interference, reduce the possibility of electromagnetic pulses coupling into the second accommodating cavity 12, and thus improve the electromagnetic compatibility of the second circuit board 3. It can achieve a seal on the second accommodating cavity 12, effectively preventing the intrusion of external environmental factors such as moisture and dust, and protecting the first circuit board 2 inside the second accommodating cavity 12 from damage.

[0053] The electrical control box 10 of the present invention utilizes a first accommodating cavity 11 and a second accommodating cavity 12, spaced apart in a first direction, on the box body 1. This allows for more functionality within a limited space, thereby increasing assembly density and reducing the overall volume of the electrical control box 10. The first accommodating cavity 11 is open on one side facing away from the second accommodating cavity 12, forming a first opening 111. The second accommodating cavity 12 is open on one end along a second direction, forming a second opening 121. The first circuit board 2 is housed within the first accommodating cavity 11, and the second circuit board 3 is housed within the second accommodating cavity 12. This allows for access to the first circuit board 2 only through the first opening 111, while access to the second circuit board 3 only through the second opening 121. This allows for electrical isolation between the first and second circuit boards 2, 3, preventing mutual interference. Furthermore, the first cover 4, which covers the first opening 111, and the second cover 5, which covers the second opening 121, effectively shield against external electromagnetic interference and prevent the intrusion of external elements such as moisture and dust, making the electrical control box 10 relatively safe and reliable.

[0054] In some embodiments of the present invention, Figure 4 and Figure 8 As shown, an annular limiting boss 112 is provided on the bottom wall of the first accommodating cavity 11 opposite to the first opening 111, and the first circuit board 2 is arranged in the limiting boss 112, so that the position of the first circuit board 2 can be fixed in the limiting boss 112, thereby preventing the first circuit board 2 from shaking in the first accommodating cavity 11 during the movement of the electric control box 10, and preventing the first circuit board 2 from being damaged during the movement.

[0055] In some embodiments of the present invention, Figure 7 and Figure 8A limiting buckle 1121 is provided on the inner wall of the limiting boss 112, and the first circuit board 2 is clamped between the limiting buckle 1121 and the bottom wall of the first accommodating cavity 11, and is used to limit the first circuit board 2 in the first direction, preventing the first circuit board 2 from escaping from the limiting boss 112 from a position close to the first opening 111, thereby increasing the reliability of the position of the first circuit board 2. A guide slope 1122 is provided on the side of the limiting buckle 1121 away from the bottom wall of the first accommodating cavity 11. Along the direction from the free end to the fixed end of the limiting buckle 1121, the guide slope 1122 is inclined toward the direction away from the bottom wall of the first accommodating cavity 11, so that when the first circuit board 2 is installed in the first accommodating cavity 11, the guide slope 1122 can provide guidance for the assembly of the first circuit board 2. During the assembly process, the first circuit board 2 squeezes the guide slope 1122, and the limiting buckle 1121 is inclined toward the direction away from the first circuit board 2. The first circuit board 2 enters between the limiting buckle 1121 and the bottom wall of the first accommodating cavity 11, and the limiting buckle 1121 returns to its position, thereby limiting the first circuit board 2.

[0056] In some embodiments of the present invention, Figure 4 and Figure 8 As shown, the limiting boss 112 is spaced apart from the inner wall of the first accommodating cavity 11, and the outer peripheral wall of the limiting boss 112 and the inner wall of the first accommodating cavity 11 define a winding groove 113. The wires electrically connected to the first circuit board 2 can be wound around the winding groove 113 to limit the wires, so that the wiring in the first accommodating cavity 11 is smoother.

[0057] In some embodiments of the present invention, Figure 4 and Figure 8 As shown, the outer circumferential wall of the limiting boss 112 and / or the inner circumferential wall of the first accommodating cavity 11 are provided with a plurality of wire retaining clips 114 spaced apart along the circumferential direction of the limiting boss 112. It is understood that the outer circumferential wall of the limiting boss 112 is provided with a plurality of wire retaining clips 114 spaced apart along the circumferential direction of the limiting boss 112; or the inner circumferential wall of the first accommodating cavity 11 is provided with a plurality of wire retaining clips 114 spaced apart along the circumferential direction of the limiting boss 112; or the outer circumferential wall of the limiting boss 112 and the inner circumferential wall of the first accommodating cavity 11 are provided with a plurality of wire retaining clips 114 spaced apart along the circumferential direction of the limiting boss 112. Wires electrically connected to the first circuit board 2 can be retained within the wire retaining clips 114, thereby limiting the position of the wires and ensuring smoother routing within the first accommodating cavity 11.

[0058] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the box body 1 has a notch 13, which is located on the side of the second accommodating cavity 12 facing the first accommodating cavity 11. Along the second direction, the notch 13 is located on the side of the first accommodating cavity 11 close to the second opening 121, which is convenient for achieving the spacing between the first opening 111 and the second opening 121, and for achieving the spacing between the first accommodating cavity 11 and the second accommodating cavity 12.

[0059] like Figure 2 and Figure 3 As shown, the box body 1 has a first wire outlet 14 and a second wire outlet 15. The first wire outlet 14 is located between the notch 13 and the first accommodating cavity 11 and communicates with the notch 13 and the first accommodating cavity 11. The second wire outlet 15 is located between the second accommodating cavity 12 and the notch 13 and communicates with the notch 13 and the second accommodating cavity 12. The first wire outlet 14 and the second wire outlet 15 are in the third direction (such as Figure 1 The first, second and third directions are spaced apart in the third direction (as shown), and the first, second and third directions are perpendicular to each other. The first wire outlet 14 can lead out the wires in the first accommodating cavity 11, and the first wire outlet 14 can lead out the wires electrically connected to the first circuit board 2; the second wire outlet 15 can lead out the wires in the second accommodating cavity 12, and the second wire outlet 15 can lead out the wires electrically connected to the second circuit board 3. The first wire outlet 14 and the second wire outlet 15 are spaced apart in the third direction, and the wires electrically connected to the first circuit board 2 and the wires electrically connected to the second circuit board 3 are spaced apart in the third direction, which can make the wiring of the first circuit board 2 and the second circuit board 3 partitioned, making the wiring of the electric control box 10 smoother, making the entire electric control box 10 look more beautiful, and the manufacturing efficiency is higher. And during subsequent maintenance, the outlets of the first circuit board 2 and the second circuit board 3 can be more clearly distinguished, which is convenient for maintenance.

[0060] In some embodiments of the present invention, Figure 2 As shown, the electric control box 10 also includes a wire-holding structure 6, which includes a wire-holding portion 61. Along the third direction, the wire-holding portion 61 is disposed between the first wire outlet 14 and the second wire outlet 15, thereby separating the first wire outlet 14 from the second wire outlet 15. This allows for partitioned routing of the first circuit board 2 and the second circuit board 3, resulting in smoother wiring of the electric control box 10, a more aesthetically pleasing appearance, and improved manufacturing efficiency. Furthermore, during subsequent maintenance, the wires of the first circuit board 2 and the second circuit board 3 can be clearly distinguished, facilitating maintenance.

[0061] Furthermore, if Figure 2 and Figure 4As shown, the wire-holding structure 6 further includes a first wire-passing clamp 62 and a second wire-passing clamp 63. The first wire-passing clamp 62 is provided on a side of the wire-holding portion 61 close to the first wire outlet 14. The first wire-passing clamp 62 extends along a third direction toward a side away from the second wire outlet 15. The first wire-passing clamp 62 can further limit the wires in the first accommodating cavity 11 at the first wire outlet 14, ensuring that the wires electrically connected to the first circuit board 2 can move toward a side away from the second wire outlet 15, thereby increasing the reliability of the routing of the wires electrically connected to the first circuit board 2. The second wire-passing clamp 63 is provided on a side of the wire-holding portion 61 close to the second wire outlet 15. The second wire-passing clamp 63 extends along a third direction toward a side away from the first wire outlet 14. The second wire-passing clamp 63 can further limit the wires in the second accommodating cavity 12 at the second wire outlet 15, ensuring that the wires electrically connected to the second circuit board 3 can move toward a side away from the first wire outlet 14, thereby increasing the reliability of the routing of the wires electrically connected to the second circuit board 3.

[0062] like Figure 4 As shown, the wire clamping portion 61 and the second wire-passing clamp 63 jointly define a wire-passing space 122. The end of the wire-passing space 122 away from the first wire outlet 14 is open. The wires electrically connected to the second circuit board 3 are separated from the wires electrically connected to the first circuit board 2. This allows the first circuit board 2 and the second circuit board 3 to be routed separately, making the wiring of the electric control box 10 smoother, making the entire electric control box 10 more beautiful, and improving manufacturing efficiency. In addition, during subsequent maintenance, the outlet wires of the first circuit board 2 and the second circuit board 3 can be clearly distinguished, facilitating maintenance.

[0063] In some embodiments of the present invention, Figure 1 and Figure 6 As shown, a limiting protrusion 1211 extending toward the first accommodating cavity 11 is provided at the edge of the second opening 121 on the side away from the first accommodating cavity 11. Along the third direction, the limiting protrusion 1211 is located on the side of the second wire outlet 15 facing away from the first wire outlet 14. The limiting protrusion 1211 further limits the position of the wires electrically connected to the second circuit board 3, keeping the wires electrically connected to the second circuit board 3 away from the wires electrically connected to the first circuit board 2. This allows for separate routing of the first and second circuit boards 2, 3, and streamlined wiring in the electrical control box 10, making the entire electrical control box 10 more aesthetically pleasing and improving manufacturing efficiency. Furthermore, during subsequent maintenance, the wires exiting the first and second circuit boards 2, 3, can be clearly distinguished, facilitating repairs.

[0064] In some embodiments of the present invention, Figure 1As shown, the first circuit board 2 is a low-current circuit board 21, and the second circuit board 3 is a high-current circuit board 31. The second accommodating cavity 12 is used for the installation of the high-current circuit board 31 and the routing of the motor, PTC (Positive Temperature Coefficient Thermistor), power line, etc. on the high-current circuit board 31. The low-current area is used for the installation of the low-current circuit board 21 and the routing of low-current terminals such as stepping motors. The low-current circuit board 21 is mainly used for transmitting data and control signals and is sensitive to electromagnetic interference. The high-current circuit board 31 will generate an electromagnetic field during operation, which will interfere with the signal of the low-current circuit board 21. The separate arrangement of the high-current circuit board 31 and the low-current circuit board 21 can reduce electromagnetic interference and ensure the stability and reliability of the low-current signal.

[0065] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, a wire-passing notch 16 is provided on one side of the box body 1 away from the first wire outlet 14 along the third direction. The wire-passing notch 16 is communicated with the second opening 121 and the second accommodating cavity 12. A wire fixing seat 161 is provided in the wire-passing notch 16. The electric control box 10 also includes a wire fixing clamp 162. The wire fixing clamp 162 is located between the second cover plate 5 and the wire fixing seat 161 and defines a wire-passing hole 163 together with the wire fixing seat 161. Thicker wires such as the power cord of the high-voltage circuit board 31 can be passed through the wire-passing hole 163 to increase the reliability of the position of the power cord.

[0066] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the outer wall of the box body 1 is provided with a wire buckle 17, and the PTC wire of the high-voltage circuit board 31 can be clamped in the wire buckle 17, so that the layout of the PTC wire is more reasonable and the reliability of the position of the PTC wire is increased.

[0067] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, one end of the two opposite ends of the first cover plate 4 along the second direction is engaged with the box body 1 , and the other end is connected to the box body 1 via a fastener. The connection between the first cover plate 4 and the box body 1 is relatively simple and reliable.

[0068] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, one end of the two opposite ends of the second cover plate 5 along the first direction is engaged with the box body 1 , and the other end is connected to the box body 1 via a fastener. The connection between the second cover plate 5 and the box body 1 is relatively simple and reliable.

[0069] The following describes an electric control box 10 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0078] The present invention further provides an air conditioner 100 having the electric control box 10 of the above embodiment.

[0079] like Figure 9 As shown, the air conditioner 100 according to the embodiment of the present invention includes a housing 20 and the above-mentioned electric control box 10 .

[0080] Specifically, if Figure 9 and Figure 10 As shown, the electrical control box 10 is disposed within the housing 20. The housing 20 protects the internal structure of the air conditioner 100, preventing damage caused by exposure to the internal structure of the air conditioner 100, thereby extending the service life of the air conditioner 100 and improving its appearance. The housing 20 has an air inlet and an air outlet 30. The air inlet extends along the height of the air conditioner 100 and is located directly behind the housing 20. The air outlet 30 is located on the front side of the housing 20.

[0081] Furthermore, an air inlet grille is provided at the air inlet. On the one hand, the air inlet grille can prevent hands or other foreign objects from entering the interior of the air conditioner 100, protecting the safety of the user and ensuring the normal operation of the air conditioner 100; on the other hand, the air inlet grille can prevent insects, rodents, etc. from entering the shell 20 of the air conditioner 100 and causing damage to the air conditioner 100, thereby ensuring the normal operation of the air conditioner 100 and ensuring the beautiful appearance of the air conditioner 100.

[0082] Optionally, the air inlet grille is detachably connected to the shell 20. The air inlet grille can ensure the beautiful appearance of the shell 20. After the air inlet grille is removed, it is convenient to repair and replace components in the air conditioner 100. At the same time, it is convenient to clean the air inlet grille, avoiding dust accumulation on the air inlet grille due to long-term use.

[0083] According to the air conditioner 100 of the present invention, the aforementioned electronic control box 10 is provided with a first accommodating cavity 11 and a second accommodating cavity 12 spaced apart in a first direction on the box body 1. This allows for more functions to be implemented within a limited space, thereby increasing assembly density and reducing the overall volume of the electronic control box 10. The first accommodating cavity 11 is open on one side facing away from the second accommodating cavity 12, forming a first opening 111. The second accommodating cavity 12 is open on one end along the second direction, forming a second opening 121. The first circuit board 2 is located within the first accommodating cavity 11, and the second circuit board 3 is located within the second accommodating cavity 12. This allows for access to the first circuit board 2 by opening only the first opening 111, while access to the second circuit board 3 by opening only the second opening 121. This allows for electrical isolation between the first and second circuit boards 2, 3, preventing mutual interference. Furthermore, the first cover 4, which covers the first opening 111, and the second cover 5, which covers the second opening 121, effectively shield against external electromagnetic interference and prevent the intrusion of external elements such as moisture and dust, making the electronic control box 10 safe and reliable.

[0084] In some embodiments of the present invention, along the second direction, a positioning pin 18 is provided on the side of the box body 1 away from the second opening 121, and a positioning hole cooperating with the positioning pin 18 is provided on the shell 20. When assembling the electric control box 10, the positioning pin 18 on the box body 1 is passed through the positioning hole, and a mounting plate 19 is provided on the end of the box body 1 away from the positioning pin 18, and a through hole 191 is provided on the mounting plate 19. After the positioning pin 18 is passed through the positioning hole, the fastener is fixed to the shell 20 through the through hole 191, thereby realizing a fixed connection between the electric control box 10 and the shell 20.
