Example Embodiment

[0033] The present invention will be further described below with reference to the drawings and embodiments.

[0034] See Figure 1-Figure 16 The air guide device of the indoor unit of the air conditioner includes an air outlet frame 5 arranged on the indoor unit, an air outlet is provided in the air outlet frame 5, and an air guide plate is arranged at the air outlet.

[0035] The wind deflector includes an outer wind deflector 1, and the width of the outer wind deflector 1 ≥ the width of the wind deflector. The outer wind deflector 1 has a T-shaped structure with a wide top and a narrow bottom. The width of the upper end of the outer wind deflector 1 = the width of the panel 6 on the indoor unit. The air outlet frame 5 is provided with a motor assembly 3, and the output shaft of the motor assembly 3 is connected with the shaft hole of the outer air deflector 1. The outer wind deflector 1 is arranged at the lower part of the air outlet.

[0036] In order to further improve the effect of the wind guide, the wind guide plate further includes an inner wind guide plate 2 which is arranged on the upper part of the air outlet. The air outlet frame 5 is provided with a small motor 4, and the output shaft of the small motor 4 is connected with the shaft hole of the inner air deflector 2.

[0037] The following is an example of the width of the wind deflector 1>the width of the air outlet.

[0038] In the running state, the outer wind deflector 1 is provided by the clockwise torque provided by the two sets of motor components 3 at the same time, and the inner wind deflector 2 is rotated downward to open the air outlet by the clockwise torque provided by the small motor 4. Provide comfortable and wide-angle air supply.

[0039] The outer air deflector 1 is provided by the counterclockwise torque provided by the two sets of motor components 3 at the same time, the inner air deflector 2 is rotated upwards at the same time by the counterclockwise torque provided by the small motor 4, and the outer air deflector 1 closes the air outlet .

[0040] The motor assembly 3 includes a motor 12 and a gear transmission assembly 7. The motor 12 is assembled with the gear transmission assembly 7 through shaft holes and controls the movement of the gear transmission assembly 7.

[0041] The gear transmission assembly 7 includes a housing 8 of the gear transmission assembly, a cover 11 of the gear transmission assembly, a large gear 9 and a small gear 10.

[0042] The main functions of the box 8 of the gear transmission assembly are as follows: 1) The large gear 9 and the small gear 10 are assembled together through the box 8 of the gear transmission assembly, so that the two gears can mesh with each other to transmit torque; 2) the gear transmission assembly There are two sets of screw holes on the box 8: the first screw hole group 18 and the second screw hole group 19, the first screw hole group 18 is used to fix the motor 12 on the gear transmission assembly 7; the second screw hole group 19 is used to fix the motor assembly 3 on the air outlet frame 5.

[0043] The cover 11 of the gear transmission assembly is covered on the housing 8 of the gear transmission assembly to form a closed space to prevent foreign objects such as dust from entering the housing 8 of the gear transmission assembly to protect the small gear 10 and the large gear 9, thereby Ensure the use function of the gear transmission assembly 7.

[0044] The pinion 10 and the motor 12 are connected with a flat hole 17 at one end. The motor 12 and the pinion 10 are matched with a flat shaft 20. The motor 12 controls the movement of the pinion 10 through the shaft hole. The driving tooth 16 at the other end of the pinion 10 It meshes with the driven tooth 14 of the large gear 9 to control the movement of the large gear 9.

[0045] One end of the big gear 10 connected with the outer air deflector 1 is a square shaft 15, the outer air deflector 1 and the big gear 10 are matched by a square hole 13, and the big gear 9 controls the movement of the outer air deflector 1 through the shaft hole. The function of opening and closing the air outlet. The driven tooth 14 at the other end of the large gear 9 meshes with the driving tooth 16 of the small gear 10. The square shaft 15 and the square hole 13 here are a specific application example in which the output shaft of the motor assembly 3 is connected with the shaft hole of the outer wind deflector 1 described above.

[0046] The structure of the flat hole 21 on the inner air deflector 2 is matched with the flat shaft 20 of the small motor 4, so that the small motor 4 can directly control the up and down rotation of the inner air deflector 2; the inner air deflector 2 is located inside the air outlet , Staggered inside and outside with the outer air deflector 1. When the indoor unit of the air conditioner is in the closed state, the outer wind deflector 1 covers the inner wind deflector 2 from the outside, and the inner wind deflector 2 is invisible from the outside. The flat shaft 20 and the flat hole 21 here are a specific application example in which the output shaft of the small motor 4 and the shaft hole of the inner wind deflector 2 are connected.

[0047] In the closed state, the outer wind deflector 1 and the panel 6 of the indoor unit of the air conditioner have a smooth transition in contours, making the appearance of the indoor unit of the air conditioner more beautiful.

[0048] by Figure 15-16 It can be seen that the upper and lower air guiding effect of this product is larger in the upper and lower air guiding angle range than the conventional double air guiding air conditioner indoor unit, and the air guiding distance is 1.53 times that of the conventional double air guiding air conditioner indoor unit. . The left-right air guiding effect of this product is 1.7 times that of the conventional double-blade air-conditioning indoor unit in the left-right angle range, and 1.65 of the conventional double-blade air-conditioning indoor unit in the air guiding distance. Times. The above data show that the air guiding effect of this product is more ideal.

[0049] When the width of the outer air deflector 1 = the width of the air outlet, for example, the thickness of the air outlet frame 5 at the outermost air outlet can be set to be quite thin, and the thickness of the air outlet frame 5 is gradually increased, etc. . In this case, the same technical effect as the above can still be obtained.

[0050] The above are only specific embodiments of the present invention, and do not limit the scope of protection of the present invention; the width of the outer wind deflector can be greater than or equal to the width of the air outlet, and any replacements made without violating the concept of the present invention Improvements fall within the protection scope of the present invention.
