DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the description.

[0032] like Figures 1 to 3As shown, the present invention discloses an air guide assembly, including a first drive unit 10, a swing rod 20, a second drive unit 30 and an air guide plate 40, wherein the first drive unit 10 has a first output shaft; one end of the swing rod 20 is drivingly connected to the first output shaft, and the swing rod 20 can swing under the drive of the first drive unit 10; the second drive unit 30 is mounted on the swing rod 20, and the second drive unit 30 has a second output shaft; the air guide plate 40 is rotatably arranged on the swing rod 20, and the air guide plate 40 is drivingly connected to the second output shaft; the swing rod 20 includes a drive box 22, and the second drive unit 30 is installed in the drive box 22. The air guide assembly of the present invention can be installed in the drive box 22 by setting the drive box 22, so that the second drive unit 30 can be better fixed on the swing rod 20, which is more reliable. In addition, the second drive unit 30 is built-in to reduce the vibration noise directly transmitted to the air guide plate, effectively prevent the vibration from affecting the rotation of the air guide plate, and improve the reliability and stability of operation.

[0033] In the above embodiment, the first end of the swing rod 20 is drivingly connected to the first drive shaft, and the drive box 22 is connected to the second end of the swing rod 20. The wind guide assembly of the present invention arranges the drive box 22 at the second end of the swing rod 20. Since the second end of the swing rod 20 is an exposed end, the second drive unit 30 is built-in to make it more beautiful.

[0034] In the above embodiment, the drive box 22 has an installation space 221, and the second drive unit 30 is installed in the installation space 221; a wiring channel 211 is provided in the swing arm 20, and a wire outlet hole 212 is provided on the swing arm 20, one end of the wiring channel 211 is connected to the installation space 221, and the other end of the wiring channel 211 is connected to the wire outlet hole 212. The air guide assembly of the present invention can install the components of the second drive unit 30 including the motor in the installation space 221 by providing the installation space 221 and the wiring channel 211, and the motor wire of the motor is passed through the wiring channel 211 and passed through the wire outlet hole 212, so that the wiring of the motor wire is more beautiful, not easy to wear, and prevents winding.

[0035] In a conventional wind guide device, the driving unit for driving the swing arm is usually arranged in the wind outlet duct. Such a structure will cause the wind to form a turbulent flow when passing through the driving unit, thereby affecting the wind outlet. In order to solve the above problem, in the above embodiment, as shown in FIG. Figures 3 to 7As shown, the air guide assembly further includes an air outlet panel 50, a collecting air duct 60 and an air outlet frame 7, wherein the air outlet panel 50 has an air outlet 51; one end of the collecting air duct 60 is connected to the air outlet 51; the air outlet frame 70 is arranged on the air outlet panel 50, and the air outlet frame 70 is located outside the collecting air duct 60. The first drive unit 10 is installed on the air outlet panel 50 through the air outlet frame 70, so that the first drive unit 10 is located outside the collecting air duct 60. The air guide assembly of the present invention collects the turbulence in the air duct 60 by arranging the first drive unit 10 outside the collecting air duct 60, thereby improving the comfort.

[0036] In the above embodiment, by changing the position of the first driving unit 10, the turbulence in the collecting duct 60 can be avoided. However, since the position of the first driving unit 10 is changed, the swing range of the air guide plate will be affected. Therefore, in order to increase the swing range of the air guide plate 40, the air guide plate 40 can also be completely closed on the air outlet 41. Figure 3 and Figure 4 As shown, the swing center of the swing rod 20 is located outside the air collecting duct 60. Figure 3 As shown, the swing rod 20 includes a first linear swing arm 21a and a second linear swing arm 21b, and the first linear swing arm 21a and the second linear swing arm 21b are connected to form an avoidance bend.

[0037] During use, the air guide plate 40 matches the air outlet 51. Figure 5 As shown, the air guide plate 40 has a first position in which the air outlet 51 is opened, and Figure 4 As shown, the second position of closing the air outlet 51; driven by the first driving unit 10, the swing rod 20 drives the air guide plate 40 to switch between the first position and the second position; when the air guide plate 40 moves to the second position, the edge of the air outlet 51 is located in the avoidance bend. The air guide assembly of the present invention is configured to be L-shaped, so that the swing rod 20 can avoid the edge of the air outlet 51 during the swinging of the air guide plate 40, thereby increasing the swinging range of the air guide plate 40. At the same time, it can also ensure that when the air guide plate 40 is closed, the air outlet 51 can be completely closed without a gap, thereby preventing dust from entering the air outlet and making the appearance more beautiful.

[0038] In the above embodiment, the driving box 22 includes two sub-shells, which are snap-fitted to enclose the installation space 221. The air guide assembly of the present invention uses two sub-shells to facilitate the installation and maintenance of the second driving unit 30.

[0039] In the above embodiment, the swing rod 20 is integrally formed with the drive box 22. The wind guide assembly of the present invention can make the installation process more convenient, the structure more solid, and the appearance more beautiful by integrally forming the swing rod 20 and the drive box 22.

[0040] In the above embodiment, the first drive unit 10 includes a speed change gear box 11 and a first motor 12, the output end of the speed change gear box 11 is a first output shaft; the output shaft of the first motor 12 is drivingly connected to the input end of the speed change gear box 11. The air guide assembly of the present invention uses a speed change gear box to increase the reduction ratio of the gear. As the reduction ratio increases, the torque can be increased, the load of the first motor 12 can be reduced, and the vibration of the first motor 12 can be reduced; in addition, the speed reduction can make the movement smoother, thereby reducing noise.

[0041] In the above embodiment, a display device 80 is further included. The display device 80 is arranged on the air outlet panel 50 and is used to display the current state of the air conditioner and / or the position of the air guide plate.

[0042] like Figure 2 and Figure 6 As shown, a swing rod 20 and a first driving unit 10 are provided on both sides of the air outlet 51, so that the swinging motion of the air guide plate can be more stable.

[0043] According to another embodiment of the present invention, an air conditioner is disclosed, comprising the above-mentioned air guide assembly.

[0044] The air conditioner has cooling mode and heating mode:

[0045] In the cooling mode, the first drive unit 10 drives the swing arm 20 to move to the first preset position, and the second drive unit 30 drives the air guide plate 40 to rotate to the second preset position, and the cold air is blown toward the roof under the guidance of the air guide plate 40; in the heating mode, the first drive unit 10 drives the swing arm 20 to move to the first preset position, the air guide plate 40 is in the initial position, and the hot air is blown toward the ground under the guidance of the air guide plate 40.

[0046] like Figure 8 As shown, in the cooling mode, the air guide plate 40 moves upward with an inclination angle of about 10° to 15° to the horizontal direction. The airflow comes from the unit inside the duct. The airflow passes through the collecting duct 60 and the upward air guide plate 40, and the airflow can be guided and transported. Since the air outlet 51 is usually close to the indoor wall, the airflow meets the "Coanda effect", and the airflow is evenly discharged along the wall, and the air supply distance is farther, thereby realizing "rain-type cooling" over a larger area.

[0047] like Fig. 9 As shown, in the heating mode, the air guide plate is tilted downward, and the tilt angle is about 60° to 75° with the vertical direction. The airflow comes from the unit inside the duct, and the airflow is guided and transported through the collecting duct 60 and the downward air guide plate 40. Due to the larger air guide surface, the air supply distance is longer, and the airflow goes down directly to the ground, so that the user can quickly reach a warm and comfortable level and realize "carpet-style heating".

[0048] Compared with the fixed diffusers or lily leaf structures on the market, the design of the air guide component that can freely control movement greatly improves the user experience. With the fixed air outlet structure, users can only adjust the air outlet temperature of the air conditioner as a whole when they feel hot or cold, but the controllable air guide plate rotation mechanism can transport air according to the user's instructions. At the same time, the design of the large air guide plate makes the air guide surface larger than the traditional air guide plate, and at the same time, it cooperates with the multi-angle movement adjustment to meet the distribution of cold and warm, and achieve the function of quickly adjusting the indoor temperature to different degrees. When the air conditioner is turned off and the air outlet components are closed, the overall gapless design cooperates with the interior decoration, greatly improving the indoor viewing effect.

[0049] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
