[0052] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0053] The following describes an electric control box assembly 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0054] refer to Figure 5-Figure 7 The electric control box assembly 1 according to the embodiment of the first aspect of the present invention includes an outer box body 11, an inner box body 12, an electric control board 13 and components 14. The outer box body 11 can be a metal part, so that the outer box body 11 has a high structural strength. The inner box body 12 is arranged in the outer box body 11, and the outer box body 11 can protect the inner box body 12. The inner box body 12 is an insulating part, for example, the inner box body 12 is a plastic part. The electric control board 13 is arranged in the inner box body 12, and the inner box body 12 can protect the electric control board 13. Since the inner box body 12 is an insulating part, it can prevent the electric control board 13 from directly contacting the outer box body 11 and causing a short circuit.

[0055] The component 14 can be a transformer. The component 14 is arranged in the outer box body 11 and outside the inner box body 12, so that the outer box body 11 can protect the component 14 and the component 14 does not interfere with the setting of the electronic control board 13. The component 14 is connected to the inner box body 12, for example, the component 14 is connected to one side of the inner box body 12.

[0056] Since the components 14 and the inner box body 12 are connected, the components 14 and the inner box body 12 form a whole. The components 14 and the inner box body 12 constitute a module of the electric control box assembly 1, realizing the integration of the inner box body 12, the electric control board 13 and the components 14.

[0057] When assembling the electric control box assembly 1, the electric control board 13 can be first placed in the inner box body 12, and then the components 14 and the inner box body 12 can be connected so that the components 14 and the inner box body 12 form a whole. Finally, the integrated components 14 and inner box body 12 can be installed in the outer box body 11. Compared with installing the components 14 and the inner box body 12 separately in the outer box body 11, the electric control box assembly 1 in the present application facilitates modular assembly of the electric control box assembly 1 by first integrating the components 14 and the inner box body 12 and then installing the integrated components 14 and the inner box body 12 in the outer box body 11, thereby improving the assembly efficiency of the electric control box assembly 1.

[0058] According to the electric control box assembly 1 of the present invention, by arranging the components 14 in the outer box body 11 and outside the inner box body 12, and connecting the components 14 to the inner box body 12, the components 14 and the inner box body 12 are integrated, which is beneficial to the modular assembly of the electric control box assembly 1 and improves the assembly efficiency of the electric control box assembly 1.

[0059] refer to Figure 5-Figure 7 According to some embodiments of the present invention, a mounting bracket 121 is provided on the outer wall of the inner box body 12, and the component 14 is connected to the mounting bracket 121. This design facilitates connecting the component 14 to the inner box body 12 and can ensure the reliability of the connection, while improving the structural strength of the inner box body 12. For example, the component 14 can be connected to the mounting bracket 121 by screws.

[0060] refer to Figure 5-Figure 7 Optionally, the mounting bracket 121 is connected to the outer box body 11. For example, the mounting bracket 121 can be connected to the outer box body 11 by screws. This design facilitates fixing the inner box body 12 to the outer box body 11, thereby fixing the integrated inner box body 12 and components 14 to the outer box body 11, which is beneficial to improving the structural strength and stability of the electric control box assembly 1.

[0061] refer to Figure 6 and Figure 7Furthermore, the mounting bracket 121 can be connected to the lower side of the inner box body 12, and the mounting bracket 121 is connected to the outer box body 11 through a first fastener 12111. For example, the first fastener 12111 is a screw. A first positioning lug 1211 is formed on the inner box body 12, and the first positioning lug 1211 can be formed at the top of the inner box body 12. A first pre-positioning hole 111 that cooperates with the first positioning lug 1211 is formed on the outer box body 11, and the first pre-positioning hole 111 can be formed at the top of the outer box body 11. When installing the inner box body 12 connected with the component 14 into the outer box body 11, the first positioning lug 1211 of the inner box body 12 can be inserted into the first pre-positioning hole 111 of the outer box body 11 to achieve pre-positioning of the inner box body 12 and the component 14. Then, the mounting bracket 121 is connected to the outer box body 11 through the first fastener 12111, so that the inner box body 12 and the component 14 can be easily and quickly installed in the outer box body 11.

[0062] refer to Figure 5-Figure 7 According to some optional embodiments of the present invention, the inner box body 12 and the mounting bracket 121 are integrally formed, for example, by integral injection molding. This provides a high connection strength between the inner box body 12 and the mounting bracket 121, making the integrated inner box body 12 and components 14 more stable and simplifying the assembly process of the electric control box assembly 1.

[0063] refer to Figure 5-Figure 7 According to some optional embodiments of the present invention, the mounting bracket 121 includes two sub-mounting brackets 121a that are opposite to and spaced apart from each other. The component 14 is accommodated in the accommodation space defined by the two sub-mounting brackets 121a and the inner box body 12. The side walls of the component 14 can abut against the side walls of the two sub-mounting brackets 121a, and the top wall of the component 14 can abut against the bottom wall of the inner box body 12, so that the component 14 is more reliably and stably fixed on the mounting bracket 121. Moreover, the component 14 is accommodated in the accommodation space, which can prevent the component 14 from shaking and colliding with the outer box body 11.

[0064] refer to Figure 5-Figure 7Furthermore, sub-mounting bracket 121a includes a mounting plate 1212 and mounting posts 12121 disposed on mounting plate 1212. Mounting posts 12121 may be formed on a side of mounting plate 1212 away from component 14, allowing component 14 to be accommodated within the accommodation space defined by the mounting plates 1212 of the two sub-mounting brackets 121a. The sidewalls of component 14 may substantially conform to mounting plate 1212, ensuring stable installation of component 14. Component 14 is provided with a connecting lug 141. A second fastener 121211 is adapted to penetrate through connecting lug 141 and mounting post 12121 to connect component 14 to mounting bracket 121. For example, screw holes may be formed in connecting lug 141, and second fastener 121211 may be a screw. The second fastener 121211 is passed through the connecting lug 141 and the mounting column 12121 to fix the component 14 on the mounting bracket 121, so that the component 14 and the mounting bracket 121 have a higher connection strength, making the overall structure of the connected inner box body 12 and the component 14 more stable, which is beneficial to improving the structural strength and stability of the electric control box assembly 1.

[0065] refer to Figure 5-Figure 7 Furthermore, a fixing hole 131 is formed in the electric control board 13, and a fixing post 1213 is formed in the inner box body 12. A third fastener 12131 is adapted to be inserted through the fixing hole 131 and the fixing post 1213 to secure the electric control board 13 within the inner box body 12, thereby providing a high connection strength between the electric control board 13 and the inner box body 12. For example, the third fastener 12131 is a screw. The central axis of the third fastener 12131 and the central axis of the second fastener 121211 are perpendicularly arranged. For example, the central axis of the third fastener 12131 is parallel to the front-to-back direction, while the central axis of the second fastener 121211 is parallel to the top-to-bottom direction. This design facilitates insertion of the third fastener 12131 and the second fastener 121211, while ensuring a stable and reliable connection.

[0066] refer to Figure 5-Figure 7According to some embodiments of the present invention, a fixing hole 131 and a plurality of positioning holes 132 are formed on the electric control board 13, and a fixing column 1213 and a plurality of positioning columns 1214 are formed on the inner box body 12. The third fastener 12131 is suitable for passing through the fixing hole 131 and the fixing column 1213 to fix the electric control board 13 in the inner box body 12. For example, the third fastener 12131 is a screw, and the number of the positioning columns 1214 is the same as the number of the positioning holes 132 and corresponds one to one. By cooperating with multiple positioning columns 1214 and multiple positioning holes 132, and the number of positioning columns 1214 is the same as the number of positioning holes 132 and corresponds one to one, the electric control board 13 and the inner box body 12 can be preliminarily positioned so that the electric control board 13 is accurately installed in the inner box body 12. Then, the third fastener 12131 is passed through the fixing hole 131 and the fixing column 1213 to further fix the electric control board 13 in the inner box body 12, thereby improving the connection strength between the electric control board 13 and the inner box body 12.

[0067] In the description of the present invention, "plurality" means two or more.

[0068] refer to Figure 5-Figure 7 Optionally, there are three positioning posts 1214 and three positioning holes 132, all of which are distributed in a triangular pattern. For example, if the electric control board 13 is roughly rectangular, one positioning hole 132 is formed in the middle of the left end of the electric control board 13, and the other two positioning holes 132 are formed at the upper and lower portions of the right end of the electric control board 13, respectively, so that the three positioning holes 132 are distributed in a triangular pattern. By providing three positioning posts 1214 and three positioning holes 132, and by distributing the positioning posts 1214 and the positioning holes 132 in a triangular pattern, the electric control board 13 and the inner box body 12 are precisely connected, preventing the electric control board 13 from shaking within the inner box body 12.

[0069] refer to Figure 5-Figure 7According to some embodiments of the present invention, the portion of the outer box 11 that accommodates the inner box 12 is a first accommodating cavity 112, and the portion of the outer box 11 that accommodates the components 14 is a second accommodating cavity 113. The cross-sectional area of ​​the second accommodating cavity 113 is larger than the cross-sectional area of ​​the first accommodating cavity 112, and the cross-sectional area is perpendicular to the arrangement direction of the inner box 12 and the components 14. For example, the arrangement direction of the inner box 12 and the components 14 is vertical, and the cross-sectional area is parallel to the horizontal plane. Because the electronic control board 13 is a plate-shaped structure, the electronic control board 13 is relatively small in the thickness direction (the thickness direction of the electronic control board 13 is along the front-to-back direction). The inner box 12 that accommodates the electronic control board 13 can also be designed to be relatively small in the front-to-back direction, thereby reducing the cross-sectional area of ​​the first accommodating cavity 112. However, the dimensions of the component 14 in the front-to-back direction may be relatively large. For example, when the component 14 is a transformer, the dimensions of the component 14 in the front-to-back direction are relatively large, so the cross-sectional area of ​​the second accommodating cavity 113 for accommodating the component 14 needs to be designed to be relatively large to ensure that the component 14 is entirely accommodated within the outer box body 11. By designing the cross-sectional area of ​​the second accommodating cavity 113 to be larger than the cross-sectional area of ​​the first accommodating cavity 112, the space requirements of the component 14 are met. By designing the first accommodating cavity 112 to be relatively small, the overall volume of the electric control box assembly 1 is reduced while meeting the space requirements of the inner box body 12. When the electric control box assembly 1 is used in an air conditioner, it is convenient to install other components of the air conditioner, thereby reducing the volume of the entire unit.

[0070] refer to Figure 5-Figure 7 Optionally, the outer box body 11 has an open end 114, which facilitates maintenance and replacement of the inner box body 12 and components 14, as well as repair of the electronic control board 13. The portion of the outer box body 11 opposite the open end 114 is a back plate 115. The back plate 115 is stepped, with the raised portion of the stepped back plate 115 corresponding to the second accommodating cavity 113, and the recessed portion of the back plate 115 corresponding to the first accommodating cavity 112. This ensures that the cross-sectional area of ​​the second accommodating cavity 113 is larger than that of the first accommodating cavity 112, while maintaining a simple and aesthetically pleasing structure.

[0071] refer to Figure 5-Figure 7Furthermore, a mounting bracket 121 is provided on the outer wall of the inner box 12, and the component 14 is connected to the mounting bracket 121. This design facilitates connecting the component 14 to the inner box 12. For example, the component 14 can be connected to the mounting bracket 121 via screws. The inner box 12 and the mounting bracket 121 form a stepped structure. For example, the mounting bracket 121 protrudes rearward in the front-to-back direction, so that the inner box 12 and the mounting bracket 121 form a stepped structure as a whole. Because the electronic control board 13 is a plate-shaped structure, the electronic control board 13 is relatively small in the front-to-back direction. The inner box 12 that accommodates the electronic control board 13 can also be designed to have a relatively small front-to-back dimension. However, the component 14 may be larger in the front-to-back direction. Therefore, the mounting bracket 121 can protrude rearward to increase the contact area between the mounting bracket 121 and the component 14, thereby improving the connection strength between the component 14 and the mounting bracket 121. At the same time, the mounting bracket 121 protrudes backward so that the overall structure of the inner box body 12 and the mounting bracket 121 matches the structure of the outer box body 11, wherein the mounting bracket 121 protruding backward is accommodated in the second accommodating cavity 113, corresponding to the protruding part of the back plate 115; the inner box body 12 is accommodated in the first accommodating cavity 112, corresponding to the recessed part of the back plate 115, thereby improving the space utilization rate in the outer box body 11 and helping to reduce the volume of the electric control box assembly 1.

[0072] refer to Figure 5-Figure 7 According to some embodiments of the present invention, a mounting lug 116 suitable for mounting the outer box body 11 to the entire machine is formed on the outer box body 11. For example, when the electric control box assembly 1 is used in an air conditioner, the mounting lug 116 can be fixed to the front panel 32 of the air conditioner by spot welding to fix the electric control box assembly 1 in the entire machine.

[0073] refer to Figure 5-Figure 7 According to some embodiments of the present invention, two spaced-apart wiring holes 117 are formed in the outer box body 11. One of the two wiring holes 117 is suitable for routing the high-voltage electrical harness, and the other of the two wiring holes 117 is suitable for routing the low-voltage electrical harness. This design separates the high-voltage and low-voltage electrical harnesses, avoiding wiring confusion and reducing the impact between the high-voltage and low-voltage electrical harnesses. When the electrical control box assembly 1 has an electrical control box cover, the electrical control box cover is suitable for closing the open end 114 of the outer box body 11. The design of the wiring holes 117 can prevent the wiring harness from being squeezed when the outer box body 11 and the electrical control box cover are closed, thereby preventing damage to the wiring harness.

[0074] refer to Figure 1-Figure 3 According to the air conditioner of the second embodiment of the present invention, the electric control system of the air conditioner includes the electric control box assembly 1 according to the first embodiment of the present invention. For example, the air conditioner is a window air conditioner, or the air conditioner is a split wall-mounted air conditioner, or the air conditioner is a split floor-standing air conditioner.

[0075] According to the air conditioner of the present invention, by providing the above-mentioned electric control box assembly 1, the degree of modularization of the electric control box assembly 1 is high, so that the assembly efficiency of the electric control box assembly 1 is high, thereby improving the assembly efficiency of the air conditioner.

[0076] refer to Figure 1 According to some embodiments of the present invention, the air conditioner is a window air conditioner. The electric control box assembly 1 is disposed in the air conditioner and can control the air conditioner.

[0077] refer to Figure 1-Figure 4 According to some embodiments of the present invention, an air conditioner includes a chassis 2 and a fixing bracket 3. The chassis 2 is located at the bottom of the air conditioner and can support other components of the air conditioner. The fixing bracket 3 is located on the chassis 2 and provides support and improves the structural strength. The fixing bracket 3 includes a front panel 32 and a front cover 31. The front cover 31 can be placed on the front panel 32. The upper edge of the front panel 32 can be formed with a panel flange, and the panel flange is formed with a panel screw hole 321. The top wall of the front cover 31 can be formed with a cover screw hole 311 corresponding to the panel screw hole 321. The front panel 32 and the front cover 31 can be fixedly connected by screws passing through the panel screw holes 321 and the cover screw holes 311. The electric control box assembly 1 is located within the fixing bracket 3. For example, a mounting lug 116 is formed on the outer box body 11. The mounting lug 116 can be connected to the front panel 32 by spot welding.

[0078] The fixing bracket 3 has a baffle 31a extending vertically. The open end 114 of the outer box body 11 is opposite and in contact with the baffle 31a. A maintenance opening 312 is formed on the portion of the baffle 31a opposite the open end 114 of the outer box body 11. A cover 3121 is provided at the maintenance opening 312, which can be opened and closed. When the cover 3121 closes the maintenance opening 312, the electrical control box assembly 1 is substantially sealed. When the cover 3121 opens the maintenance opening 312, the open end 114 of the outer box body 11 is exposed, exposing the electrical control board 13 and components 14. This allows operators to directly repair or replace the electrical control board 13 and components 14 without having to remove the entire electrical control box assembly 1, thereby improving maintenance efficiency and reducing the difficulty of maintenance operations.

[0079] refer to Figure 1-Figure 4In some embodiments of the present invention, an air conditioner includes a chassis 2, an interior 100, and an exterior 200, both of which are mounted on the chassis 2. The interior 100 includes a fixed bracket 3, a face frame assembly 4, an indoor heat exchanger assembly 6, and an indoor fan.

An air inlet 42 and an air outlet 41 are formed on the face frame assembly 4. The indoor fan can drive indoor air into the air conditioner through the air inlet 42 to exchange heat with the indoor heat exchanger assembly 6, and the air from the air conditioner can be discharged through the air outlet 41.

[0080] The fixing bracket 3 includes a dash panel 32 and a front cover 31. The dash panel 32 is formed with a mounting hole for positioning the electronic control box assembly 1, which is adapted to be inserted into the mounting hole. The outer box body 11 is formed with mounting lugs 116, which are spot-welded to the dash panel 32 to secure the electronic control box assembly 1 to the fixing bracket 3. The front cover 31 is mounted on the dash panel 32, with the baffle 31a forming part of the front cover 31. A maintenance opening 312 on the baffle 31a faces the open end 114 of the outer box body 11, and the maintenance opening 312 also faces the mounting hole of the dash panel 32.

[0081] refer to Figure 1 and Figure 4 According to some optional embodiments of the present invention, a second positioning lug 31211 is formed at the lower end of the cover 3121, and a second pre-positioning hole 313 is formed on the baffle 31a to cooperate with the second positioning lug 31211. The cooperation between the second positioning lug 31211 and the second pre-positioning hole 313 can initially position the cover 3121 and the baffle 31a, so that the cover 3121 is accurately installed on the baffle 31a. The upper end of the cover 3121 is connected to the baffle 31a via a fourth fastener 3131, which further secures the cover to the baffle 31a and improves the connection strength between the cover and the baffle 31a. For example, the fourth fastener 3131 is a screw.

[0082] refer to Figure 1 and Figure 4According to some optional embodiments of the present invention, a wiring groove 314 is formed on the baffle 31a. The wiring groove 314 passes through the inner wall of the maintenance opening 312. The wiring groove 314 can be used for wiring, for example, for routing the wiring harness of the electric control box assembly 1. When the cover 3121 closes the maintenance opening 312, the wiring harness passes through the wiring groove 314 to prevent the cover 3121 from squeezing the wiring harness and thus preventing damage to the wiring harness. When a control panel is formed on the face frame assembly 4, the baffle 31a is close to the control panel. By forming the wiring groove 314 on the baffle 31a, since the wiring groove 314 is close to the control panel, the wiring harness connected to the control panel can be routed directly through the wiring groove 314 and enter the electric control box assembly 1, thereby avoiding the wiring harness connected to the control panel from being tangled and making the wiring of the air conditioner more reasonable.

[0083] refer to Figure 2 and Figure 3 According to some optional embodiments of the present invention, the fixing bracket includes a front panel 32 and a front cover 31. The front cover 31 is provided on top of the front panel 32. A space suitable for accommodating an air duct member 43 is defined between the front cover 31 and the front panel 32. The air duct member 43 is, for example, a foam member that has both thermal insulation and sealing functions. The front cover 31 supports and reinforces the air duct member 43. An air duct is defined within the air duct member 43, connecting the air inlet 42 and the air outlet 41 of the air conditioner. The indoor fan can drive indoor air from the air inlet 42 into the air duct and exchange heat with the indoor heat exchanger assembly 6. The air discharged from the air conditioner can be discharged from the air outlet 41. A portion of the side wall of the front cover 31 constitutes a baffle 31a.

[0084] refer to Figure 2 and Figure 3 According to some embodiments of the present invention, the electronic control system includes a first electronic control device 7 and a second electronic control device. The first electronic control device 7 is arranged on one side of the air duct member 43 of the air conditioner in the horizontal direction.

The first electronic control device can be connected to the air conditioner's fan, compressor assembly 51 and other components through a wiring harness to power these components. The second electronic control device is the above-mentioned electronic control box assembly 1. The second electronic control device can be connected to the air conditioner's fan, compressor assembly 51 and other components through a wiring harness to control these components through electrical signals. The second electronic control device can also be connected to weak current modules such as WIFI modules and negative ion modules through a wiring harness to control these components. By providing the first electronic control device 7 and the second electronic control device, it is avoided that all wiring harnesses inside the air conditioner are connected to a single electronic control device, making the wiring of the wiring harness inside the air conditioner more reasonable and convenient for maintenance.

The transformer of the electronic control box assembly 1 is connected to the power supply via a high-voltage wiring harness. The transformer is connected to the electronic control board 13. The transformer can adjust the current and voltage of the power supply to suit the operation of the electronic control board 13. The electronic control board 13 of the electronic control box assembly 1 is connected to the control modules of the air conditioner's fan, compressor assembly 51, and other components via low-voltage wiring harnesses to control these components via electrical signals. The electronic control box assembly 1 is also connected to the air conditioner's Wi-Fi module, negative ion module, control panel module, and other low-voltage modules via low-voltage wiring harnesses. The electronic control board 13 of the electronic control box assembly 1 can control these low-voltage modules via the low-voltage wiring harnesses. The high-voltage harness connecting the transformer of the electric control box assembly 1 to the power supply and the low-voltage harness connecting the electric control panel 13 to the Wi-Fi module, negative ion module, control panel module, and control module, respectively, can be routed through two wiring holes 117 of the outer box body 11, thereby separating the high-voltage and low-voltage harnesses, avoiding wiring confusion and reducing the impact between the high-voltage and low-voltage harnesses. The first electric control device 7 is connected to the power supply via the high-voltage harness, which in turn supplies power to the air conditioner's fan, compressor assembly 51, and other high-voltage components.
