[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] Example 1

[0033] like Figures 1-6 As shown, a multi-split indoor unit with lighting function includes an air conditioning wall panel 1, on which a return air vent 2 and an air outlet 3 are provided. The unit is characterized in that: a mounting groove 4 is provided on the air conditioning wall panel 1 on one side of the air outlet 3; a radiator 5 and a light fixture 7 are slidably disposed within the mounting groove 4; the heat dissipation fins of the radiator 5 can pass through the side wall of the mounting groove 4 and extend into the air outlet 3; the light fixture 7 is mounted on the mounting groove 4 by a quick-detachable fixing mechanism, which includes a mounting tube 8. A fixing hole 13 is provided on the side wall of the mounting tube 8. A limiting bead 14 is embedded in the fixing hole 13. A limiting ring 11 is slidably provided on one side of the limiting bead 14 inside the mounting tube 8, and a conical block 16 is provided on the other side of the limiting bead 14. A connecting rod 15 is fixedly provided on the conical block 16. The free end of the connecting rod 15 passes through the limiting ring 11 and is fixedly connected to a pressing block 10. A fastening spring 12 is fitted on the outside of the connecting rod 15 between the limiting ring 11 and the pressing block 10.

[0034] Preferably, a fixing bracket 6 is detachably provided on the outside of the lamp 7. The fixing mechanism installs the lamp 7 on the mounting groove 4 through the fixing bracket 6. There are at least two fixing holes 13 on the mounting tube 8, and the two fixing holes 13 are symmetrically arranged on the mounting tube 8 along the axis of the mounting tube 8. The mounting tube 8 of the fixing mechanism is connected to the fixing bracket 6 by threads. A baffle 9 is fixedly provided at one end of the mounting tube 8. The pressing block 10 slides through the baffle 9. A return spring 17 is also provided in the mounting groove 4. One end of the return spring 17 is fixedly connected to the inner wall of the mounting groove 4, and the other end is fixedly connected to the heat sink 5. The lamp 7 and the heat sink 5 are tightly fitted together, and thermal conductive grease is provided at the fitting point.

[0035] The working process of this embodiment is as follows: Before use, the lamp 7 and the mounting bracket 6 are first assembled. Then, the mounting tubes 8 are screwed onto both ends of the mounting bracket 6. Thermal grease is then applied to the side of the lamp 7 that is in contact with the heat sink 5. Next, the operator holds one end of each of the two mounting tubes 8 and presses down on the pressing block 10. At this time, the connecting rod 15 pushes the conical block 16 to move. After the limiting bead 14 loses the thrust of the conical block 16, it will move into the mounting tube 8. At the same time, the pressing block 10 will compress the fastening spring 12. After the lamp 7 and the heat sink 5 are aligned, the mounting bracket 6 is pushed, causing the lamp 7 to push the heat sink 5 into the mounting groove 4. At the same time, the heat dissipation fins on the heat sink 5 will extend from the mounting groove 4 into the air outlet 3, and the heat sink 5 will compress the return spring 17. When the other ends of the two mounting tubes 8 are inserted into the mounting holes at both ends of the mounting groove 4, the operator releases the pressing block 10. At this time, the fastening spring 12 pushes the pressing block 10 to move. The pressing block 10 will be pulled by the connecting rod 15. As the moving cone block 16 moves, it pushes the limiting bead 14 into the fixing hole 13, causing a portion of the limiting bead 14 to extend out of the fixing hole 13. This secures the mounting tube 8 and the fixing bracket 6 onto the air conditioner wall panel 1. At this point, the lamp 7 is tightly fitted to the radiator 5, and the radiator 5's cooling fins are inserted into the air conditioner's air outlet 3. The airflow generated by the air conditioner can then be used to cool the lamp 7, preventing overheating and extending its lifespan. When the lamp 7 is damaged and needs to be replaced... During dismantling, the worker first presses the pressing block 10, causing the connecting rod 15 to push the conical block 16 to move. After the limiting bead 14 loses its limit, it moves into the mounting tube 8, allowing the mounting tube 8 to be pulled out from the connection hole on the air conditioner wall panel 1. After the mounting tube 8 is pulled out, it will drive the light fixture 7 out of the mounting groove 4 through the fixing bracket 6. At this time, the radiator 5 will block the entrance of the mounting groove 4 under the push of the spring, and the heat dissipation fins of the radiator 5 will also be drawn back from the air outlet 3 and enter the mounting groove 4.

[0036] The radius of the limiting bead 14 is R, the diameter of the fixing hole is L, and the wall thickness of the mounting tube is D. Figure 6 As shown, according to the Pythagorean theorem, we can derive H = √(4R). 2 -L 2), so the radius R of the limiting bead 14 and the diameter L of the fixing hole 13 need to satisfy R>L / 2, and the radius R of the limiting bead 14 also needs to satisfy R>H+D.

[0037] The above has described one embodiment of the present application in detail, but the content is only the preferred embodiment of the present application, and cannot be considered to limit the implementation range of the present application. Any equivalent changes and improvements made according to the application scope of the present application should still belong to the patent coverage range of the present application.
