[0037] The setting of the telescopic structure can control the movement of the side sealing plate 11, so as to control the opening and closing state of the side sealing plate 11, which facilitates the air exhaust of the air conditioner indoor unit from the side air outlet 10, and can quickly increase or decrease the temperature of the indoor;

[0038] The setting of the sealing structure can make the movable plate 1 and the end face of the air conditioner indoor unit fit by twisting the adjusting screw 8, at which time the sealing pocket 21 can seal the end face of the air conditioner indoor unit, improving the air exhaust efficiency of the air conditioner indoor unit;

[0039] The setting of the angle adjusting structure can adjust the angle of the side sealing plate 11, which can adjust the angle of the air outlet when the air is out of the side, and is more flexible in use.

[0042] Wherein, by sliding the outer magnetic attraction piece 18, the inner magnetic attraction piece 29 can be driven to slide synchronously, at this time, the inner magnetic attraction piece 29 will drive the side sealing plate 11 to slide along the guide hole 301 at the bottom end of the guide plate 30 through the connecting plate 27, until the side sealing plate 11 is separated from the side air outlet 10; at this time, the side air outlet 10 is opened, the air generated by the air conditioner indoor unit will pass through the side air outlet 10 to the outside for partial lateral air outlet, so as to increase or decrease the rate of indoor temperature; on the contrary, when the side air outlet 10 is closed, the side sealing plate 11 can be driven to move synchronously by sliding the outer magnetic attraction piece 18, until the side sealing plate 11 is clamped in the inside of the side air outlet 10, so as to close the side air outlet 10, at this time, the air outlet can be realized through the front air outlet 15 of the air conditioner indoor unit, the operation is relatively simple.

[0043] As shown in Figure 1 and Figure 2 The sealing structure includes an adjusting screw 8 and a movable plate 19, the movable plate 19 is located inside the mounting frame 1, both ends of the movable plate 19 are provided with sliding rails 191, the top end and the bottom end of the inner cavity of the mounting frame 1 are fixedly connected with protrusions 20, and the two sliding rails 191 are respectively clamped on the surfaces of the two protrusions 20; the mounting frame 1 is communicated with the air outlet frame 2 through a connecting port 22, a sealing pocket 21 is arranged between the movable plate 19 and the connecting port 22, and the outer edges of the sealing pocket 21 are respectively fixedly connected with the side surface of the movable plate 19 and the outer edge of the connecting port 22; both ends of the mounting frame 1 are provided with threaded holes 9, the adjusting screw 8 is threadedly connected with the threaded hole 9, and the tail end of the adjusting screw 8 is rotatably connected with the movable plate 19;

[0045] With the scheme, when the adjusting screw 8 is screwed, the external thread on the surface of the adjusting screw 8 is screwed with the threaded hole 9, at this time, the adjusting screw 8 is fed to the inside of the mounting frame 1, because the movable plate 19 is in sliding connection with the mounting frame 1, at the same time, the movable plate 19 slides to the inside of the mounting frame 1 along the convex strip 20, until the inside surface of the movable plate 19 is attached to the outer end of the air conditioner inner unit; because the sealing pocket 21 is of elastic material, at this time, the sealing pocket 21 between the movable plate 19 and the connecting port 22 is expanded, avoiding the air blown out of the air conditioner from leaking out of the edge of the mounting frame 1, which is conducive to the guiding of the air of the air conditioner inner unit by the external air deflector; at the same time, the two movable plates 19 clamp and fix the external air deflector and the air conditioner inner unit, improving the stability between the external air deflector and the air conditioner inner unit.

[0046] As shown in Figure 1 , Figure 6 and Figure 7 , the angle adjusting structure includes an adjusting disc 16, the outer end surface of the adjusting disc 16 is provided with an end groove 161, the inner side surface of the side sealing plate 11 is symmetrically provided with two rotating plates 38, the outer side surface of the right rotating plate 38 is fixedly connected with a threaded shaft 32, the adjusting disc 16 is located on the outer side surface of one connecting plate 27, and the threaded shaft 32 penetrates through the outer end side surface of the connecting plate 27 and is connected to the inside of the end groove 161; the surface of the threaded shaft 32 is sleeved with a spring 34, the outer end of the spring 34 is provided with a limiting nut 33, and the limiting nut 33 is in threaded connection with the outer end of the threaded shaft 32; the outer side surface of one connecting plate 27 is provided with a positioning groove 36, the inner end surface of the adjusting disc 16 is fixedly connected with a positioning block 35, and the positioning block 35 is clamped in the inside of the positioning groove 36;

[0049] With this design, when the adjusting disc 16 is rotated, the limiting block 162 engages inside the limiting groove 321, causing the adjusting disc 16 to drive the threaded shaft 32 to rotate. The threaded shaft 32 then drives the side sealing plate 11 to rotate synchronously, thereby adjusting the angle of the side sealing plate 11. Simultaneously, when the adjusting disc 16 rotates, the positioning block 35 and the positioning groove 36 become misaligned, forcing the adjusting disc 16 to slide along the limiting groove 321 on the surface of the threaded shaft 32 and compressing the spring 34. After the angle of the adjusting disc 16 is adjusted, the positioning block 35 can be re-engaged inside the positioning groove 36 under the reaction force of the spring 34, thereby assisting in fixing the side sealing plate 11.
