[0078] When the motor drives the axial flow blade to rotate, part of the air in the shell enters the upper flow guide ring through the first flow guide surface 21 of the upper flow guide ring, flows to the upper air outlet grille through the second flow guide surface 22 and the third flow guide surface 23 of the upper flow guide ring, and then flows to the indoor; part of the air in the shell enters the lower flow guide ring through the first flow guide surface 21 of the lower flow guide ring, flows to the lower air outlet grille through the second flow guide surface 22 and the third flow guide surface 23 of the lower flow guide ring, and then flows to the indoor;

[0079] In summary, the flow guide ring 2 is detachably connected with the panel 1, when the flow guide ring 2 needs to be applied to different types of air conditioners, the flow guide ring 2 can be detached from the original panel and installed on the panel 1 of the corresponding air conditioner, so that the same flow guide ring 2 can be applied to different air conditioners, the use range of the same flow guide ring 2 is expanded, different flow guide rings 2 do not need to be designed, the design and processing cost of the flow guide ring 2 is reduced, and the universalization of the flow guide ring 2 is beneficial;

[0080] Different flow guide rings 2 can also be installed on the original panel to achieve different flow guide effects, ensure the matching degree of the actual needs of the air conditioner and the flow guide ring 2, improve the operation effect of the air conditioner, so that the panel 1 can adapt to different flow guide rings 2, and the use range of the panel 1 is expanded; the first flow guide surface 21 is an arc surface, has the effect of gathering wind, reduces the air inlet resistance, and improves the air inlet amount; the third flow guide surface 23 is an arc surface, has the effect of expanding wind, improves the air outlet amount, reduces the turbulence degree of air flowing through the flow guide ring 2, improves the vortex condition of air flowing through the flow guide ring 2, and reduces the noise.

[0081] The exemplary embodiments of the present disclosure are specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structure, arrangement or implementation method described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent arrangements included in the spirit and scope of the appended claims.

Claims

1. A panel assembly, characterized in that, It includes a panel and a flow guide ring, the flow guide ring being detachably mounted on the panel and compatible with different panel models; The guide ring has a mounting portion, and the panel has a mounting groove; the structure of the mounting groove is adapted to the structure of the mounting portion, and the mounting portion is embedded in the mounting groove to position the guide ring on the panel; The panel assembly also includes an air outlet grille, the outer edge of which forms a third fixing part, which is a snap fastener; the mounting part has an edge groove near the air guide ring, the edge groove forms a fourth fixing part, which is a slot, and the slot extends along the circumferential direction of the air guide ring. The outer edge of the air outlet grille is disposed in the edge groove, and the buckle is disposed in the groove. The air outlet grille is pushed along the extension direction of the groove, so that the buckle is embedded in the groove, thereby realizing the fixed connection between the air outlet grille and the mounting part. The air outlet grille is located on the air outlet side of the guide ring. The air inlet end of the air guide ring is an elastic ring, and the panel assembly further includes a support hoop embedded in the inner circumference of the elastic ring; by adjusting the circumferential dimension of the support hoop, the flow area of ​​the elastic ring can be adjusted; or, the air inlet end of the air guide ring is a folding ring, and the folding ring includes a plurality of folding parts connected in sequence; the panel assembly further includes a support hoop embedded in the inner circumference of the folding ring; by adjusting the circumferential dimension of the support hoop, the position between adjacent folding parts is changed, thereby adjusting the flow area of ​​the folding ring.

2. The panel assembly according to claim 1, characterized in that, The mounting groove has a first fixing part, the outer periphery of the guide ring has the mounting part, and the mounting part has a second fixing part. The first fixing part and the second fixing part cooperate to fix the guide ring on the panel.

3. The panel assembly according to claim 1, characterized in that, Along the airflow direction, the guide ring has a necked structure.

4. The panel assembly according to claim 3, characterized in that, Along the airflow direction, the guide ring is sequentially formed with a first guide surface, a second guide surface, and a third guide surface; the first guide surface is located at the necking structure. Both the first and third guide surfaces are arc-shaped surfaces, and the second guide surface is an arc-shaped surface, a cylindrical surface, or a conical surface; along the air inlet direction, the flow area of ​​the first guide surface gradually decreases, and the flow area of ​​the third guide surface gradually increases.

5. The panel assembly according to claim 1, characterized in that, The distance between the guide ring and the fan blade component can be adjusted by adjusting the axial position of the support hoop.

6. An air conditioner, characterized in that, The system includes an indoor unit, which comprises a housing, an axial fan blade, and a panel assembly as described in any one of claims 1-5; the panel is disposed at the air outlet end of the housing, and the air guide ring is disposed on the panel via a mounting portion; the axial fan blade is disposed inside the housing and located on the air inlet side of the air guide ring; the air outlet grille of the panel assembly is fixed to the mounting portion and located on the air outlet side of the air guide ring.
