[0049] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0050] Reference Figure 1-Figure 3 As shown, this embodiment discloses a multi-layer controller 2, including a housing 21, an inner control board 22 and an outer control board 23;

[0051] The upper part of the housing 21 is connected to a first rotating shaft assembly 24, and the lower part is connected to a second rotating shaft assembly 25. The first rotating shaft assembly 24 includes a first shaft body 241, and the second rotating shaft assembly 25 includes a second shaft body 251. The axes of the first shaft body 241 and the second shaft body 251 coincide with each other.

[0052] The inner control board 22 is connected to the inside of the housing 21;

[0053] The outer control panel 23 is located outside the inner control panel 22. The outer control panel 23 is rotatably connected to the housing 21. The upper portion of the outer control panel 23 is provided with a first connecting plate 231, and the lower portion is connected with a second connecting plate 232. The first connecting plate 231 is provided with a first oblong hole 2311, and the second connecting plate 232 is provided with a second oblong hole 2321.

[0054] The first shaft 241 is slidably connected in the first oblong hole 2311 , the length of which is greater than the diameter of the first shaft 241 ; the second shaft 251 is slidably connected in the second oblong hole 2321 , the length of which is greater than the diameter of the second shaft 241 .

[0055] It can be understood that the width of the first oblong hole 231 is not less than the diameter of the first shaft 241 , and the width of the second oblong hole 2321 is not less than the diameter of the second shaft 251 .

[0056] The inner control board 22 and the outer control board 23 are used to mount various electrical components.

[0057] Understandably, if Figure 4-Figure 5 As shown, the first oblong hole 2311 and the second oblong hole 2321 both refer to a structure with arc holes 2312 at both ends, and the arc holes 2312 at both ends are connected by a rectangular hole 2313; the first shaft body 241 can move from the arc hole at one end to the arc hole at the other end relative to the first oblong hole 2311, and similarly, the second shaft body 251 can move from the arc hole at one end to the arc hole at the other end relative to the second oblong hole 2321.

[0058] Since various electrical components are installed on the control panel, it has a certain thickness, and sufficient space must be reserved between the outer control panel 23 and the side wall of the shell 21 when the outer control panel 23 rotates, otherwise it is very easy to interfere with the electrical components and cause damage to the corresponding electrical components. Through the sliding setting of the first shaft 241 and the first oblong hole 2311, as well as the sliding setting of the second shaft 251 and the second oblong hole 2321, the outer control panel 23 can be moved left and right a certain distance, and then the opening or closing action can be realized, thereby ensuring that sufficient space is reserved between the outer control panel 23 and the side wall of the shell 21 when the outer control panel 23 rotates, thereby avoiding the occurrence of interference.

[0059] When the outer control plate 23 in the above structure rotates, the first shaft 241 is located in the arc hole at one end of the first oblong hole 2311, and the second shaft 251 is also located in the arc hole at one end of the second oblong hole 2321. The upper part of the outer control plate 23 rotates around the first shaft 241, and the lower part rotates around the second shaft 251.

[0060] The above structure adopts a double-layer control panel structure, which effectively utilizes the internal space of the shell 21, and can arrange more electrical components in the effective space. The outer control panel 23 can be rotated to a set angle, thereby greatly facilitating the assembly, testing and maintenance of the electrical components on the inner and outer control panels.

[0061] In one embodiment, if Figure 8 As shown, the first rotating shaft assembly 24 also includes a first curved plate 242, and the center of curvature of the first curved plate 242 is located on the axis of the first shaft body 241. When the outer control plate 23 rotates, the end of the outer control plate 23 rotates around the first curved plate 242 to limit the outer control plate 23 through the first curved plate 242 to prevent it from moving during rotation and maintain the continuity of rotation.

[0062] In one embodiment, if Figure 6-Figure 7 As shown, the second rotating shaft assembly 25 further includes a first stopper 252, which is used to be inserted into the second oblong hole 2321, and has a first guiding inclined surface 2521 and a second guiding inclined surface 2522, and the first guiding inclined surface 2521 and the second guiding inclined surface 2522 intersect each other.

[0063] Furthermore, the inclination angle of the first guiding slope 2521 and the second guiding slope 2522 may be 45°.

[0064] When the outer control panel 23 is opened to a certain angle, the bottom edge of the outer control panel 23 contacts the first limit piece 252. The outer control panel 23 continues to be opened, and the outer control panel 23 will slide to the top along the first guide slope 2521 and fall to the initial height along the second guide slope 2522, so that the first limit piece 252 completely enters the second oblong hole 2321, so that the outer control panel 23 is limited. At this time, the outer control panel 23 can no longer rotate; similarly, when closing the outer control panel 23, the bottom edge of the outer control panel 23 first contacts the second guide surface of the first limit piece 252, and slides to the top along the second guide slope 2522, and then falls to the initial height along the first guide slope 2521, so that the first limit piece 252 is disengaged from the second oblong hole 2321.

[0065] In one embodiment, if Figure 7As shown, the second rotating shaft assembly 25 also includes a second limit member 253, and the second limit member 253 includes a second arc plate 2531. The center of curvature of the second arc plate 2531 is located on the axis of the second shaft body 251. When the outer control plate 23 rotates, the end of the outer control plate 23 rotates around the second arc plate 2531 to limit the outer control plate 23 through the second arc plate 2531 to prevent it from moving during rotation and maintain the continuity of rotation.

[0066] It can be understood that when the outer control plate 23 rotates, its upper end rotates around the first arc plate 242 and its lower end rotates around the second arc plate 2531 .

[0067] Furthermore, one end of the second arc-shaped plate 2531 is folded outward to form a baffle 2532. When the outer control plate 23 rotates to the first angle, Fig.12 As shown, the outer control panel 23 is in a fully open state, and the blocking piece 2532 abuts against the outer control panel 23 to block the outer control panel 23 and prevent it from excessive rotation.

[0068] The first angle can be 90°

[0069] In one embodiment, if Figure 7 As shown, the second rotating shaft assembly 25 further includes a third stopper 254, and the third stopper 254 includes a first plate 2541. When the outer control panel 23 rotates to the second angle, the outer control panel 23 is in a fully closed state, as shown in FIG. Fig.18 As shown, the outer control plate 23 is located between the second limiting member 253 and the first plate body 2541 to block the outer control plate 23 and prevent it from excessive rotation.

[0070] The second angle may be 0°.

[0071] Furthermore, the second rotating shaft assembly 25 further includes a second plate 2542. One end of the first plate 2541 is bent outward to form the second plate 2542. The second plate 2542 and the baffle 2532 are respectively located on both sides of the second shaft 251. When the outer control plate 23 rotates to the first angle, Fig.12 As shown, one side of the outer control plate 23 abuts against the blocking piece 2532 , and the other side abuts against the second plate body 2542 , so that the outer control plate 23 can be completely limited when rotating to the first angle.

[0072] In one embodiment, if Figure 4 and Figure 6As shown, a third connecting plate 233 is provided on the side of the outer control panel 23, a slot 2331 is provided on the third connecting plate 233, and a locking block 211 is provided on the inner wall of the housing 21, and the locking block 211 is used to be inserted into the slot 2331. When the outer control panel 23 is closed, the locking block 211 is inserted into the slot 2331 to achieve complete locking of the outer control panel 23 to prevent it from opening due to external shaking and other factors. When the outer control panel 23 needs to be opened, the locking block 211 and the slot 2331 need to be disengaged first.

[0073] In one embodiment, if Figure 2 , Fig.13 and Fig.17 As shown, a bracket 212 is also connected to the inside of the housing 21, and the bracket 212 is used to be connected to the outer control panel 23 through screws 26. In order to better ensure the closing reliability, when the outer control panel 23 is completely closed, the outer control panel 23 and the bracket 212 can be screwed together by screws 26. When the outer control panel 23 needs to be opened, it is only necessary to remove the screws 26.

[0074] Specifically, the bracket 212 may be disposed on both the upper and lower parts of the housing 21 .

[0075] In one embodiment, the first rotating shaft assembly 24 is detachably connected to the housing 21 , for example, by bolts, so as to facilitate disassembly and adjustment, and also facilitate separate processing of the first rotating shaft assembly 24 .

[0076] The following is a specific example of how to use the multi-layer controller 2:

[0077] When it is necessary to open the outer control panel 23, Fig. 9 As shown, the outer control plate 23 is pushed to the left (at this time, the relative angle between the outer control plate 23 and the shell 21 is 0°), so that the slot 2331 and the locking block 211 provided on the third connecting plate 233 are disengaged, and at this time, the first shaft body 241 is shifted from the arc hole at the left end to the arc hole at the right end at the position of the first oblong hole 2311, and the second shaft body 251 is also shifted from the arc hole at the left end to the arc hole at the right end at the position of the second oblong hole 2321, and then the outer control plate 23 is rotated outward counterclockwise. At this time, the outer control plate 23 rotates relative to the first shaft body 241 and the second shaft body 251, as shown in FIG. Fig.10 As shown, when the outer control panel 23 is rotated outward to 45°, the bottom edge of the outer control panel 23 contacts the first limiting member 252, and the outer control panel 23 continues to rotate, and the outer control panel 23 slides to the top along the first guide slope 2521, and falls to the initial height along the second guide slope 2522, so that the first limiting member 252 completely enters the second oblong hole 2321 to limit the outer control panel 23. At this time, the outer control panel 23 is in a fully open state, as shown in FIG. Figure 11-Figure 12 As shown, the relative angle between the outer control board 23 and the housing 21 is 90°, one side of the outer control board 23 abuts against the blocking piece 2532, and the other side abuts against the second plate body 2542 of the third limiting member 254;

[0078] When the outer control panel 23 needs to be closed, Fig.13 As shown, the outer control plate 23 is rotated inwardly clockwise, as shown in FIG. Fig.14 As shown, the outer control plate 23 slides to the top along the second guide slope 2522 of the first stopper 252, and falls to the initial height along the first guide slope 2521, so that the first stopper 252 is disengaged from the second oblong hole 2321 and the lock is released. Fig.15 As shown, the outer control panel 23 is continuously rotated inwardly, and when the outer control panel 23 is closed, as shown in FIG. Fig.16 As shown, the relative angle between the outer control panel 23 and the housing 21 is 0°. Fig.17 As shown, the outer control panel 23 is pushed rightward again, so that the locking block 211 is inserted into the slot 2331 of the outer control panel 23 to lock the outer control panel 23. At the same time, the first shaft body 241 is shifted from the arc hole at the right end to the arc hole at the left end in the first oblong hole 2311, and the second shaft body 251 is also shifted from the arc hole at the right end to the arc hole at the left end in the second oblong hole 2321. At this point, the outer control panel 23 is completely closed. At this time, as shown in FIG. Fig.18 As shown, the outer control plate 23 is also located between the second limiting member 253 and the first plate body 2541 of the third limiting member 254 to further limit the outer control plate 23 .

[0079] The closing process of the outer layer control panel 23 is the reverse operation of the opening process.

[0080] like Figure 2 As shown, when it is necessary to perform testing or after-sales maintenance on the A and B areas of the inner control panel 22, the outer control panel 23 needs to be opened;

[0081] like Figure 3 As shown, when it is necessary to perform testing or after-sales maintenance on the outer control panel 23 and the C and D areas of the components, the outer control panel 23 needs to be closed.

[0082] like Fig.19 As shown, the above controller can be installed on the outdoor unit 1 of the air conditioner. When installing, it can be installed inside the air conditioner.

[0083] The multi-layer controller 2 of the above embodiment realizes the "stacking" of control panels in a limited space, enables the installation of more electrical components, and has a rotatable outer control panel, which can easily realize the functions of assembling, disassembling, testing and repairing each layer of control panels.

[0084] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
