The first air guiding plate is used to cooperate with the second air guiding plate to form a second air guiding port when it is away from the air guiding body, and the second air guiding plate cooperates with the air guiding body to form a third air guiding port when it is away from the air guiding body. When the first air guiding plate and the second air guiding plate are close to the air guiding body, they are both covered on the air outlet so that the air outlet is covered.

[0011] As an optional implementation, the first guide portion includes a first arc surface, and the second guide portion includes a second arc surface. The first arc surface is used to guide air to be blown out at an angle from the second air guide port, and the second arc surface is used to guide air to be blown out at an angle from the third air guide port.

[0024] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0025] See Figures 1 to 7 This utility model discloses an air conditioning air guide structure with multi-mode air supply, including an air guide body 1, an air guide component and a lifting component, wherein the lifting component is connected to the air guide component and the air guide body 1.

[0026] Specifically, the air guide body 1 is provided with an air outlet 11. The air guide assembly includes a first air guide plate 2 and a second air guide plate 3 arranged concentrically. The first air guide plate 2 is arranged around the outer periphery of the second air guide plate 3, and a first air guide port 21 is provided in the middle of the first air guide plate 2. The first air guide port 21 is connected to the air outlet 11. The lifting assembly includes a first lifting mechanism 4 and a second lifting mechanism 5, and both the first lifting mechanism 4 and the second lifting mechanism 5 can operate independently. The first lifting mechanism 4 is connected to the first air guide plate 2 and the air guide body 1 so that the first lifting mechanism 4 can drive the first air guide plate 2 to rise and fall. The second lifting mechanism 5 is connected to the second air guide plate 3 and the air guide body 1 so that the second lifting mechanism 5 can drive the second air guide plate 3 to rise and fall.

[0027] There are three operating modes: In the first operating mode, the air guide body 1 is started and the fan inside the air guide body 1 starts to blow air out from the air outlet 11. At this time, the first lifting mechanism 4 and the second lifting mechanism 5 are not started. The first air guide plate 2 and the second air guide plate 3 are both covered on the air outlet 11, and the airflow can be sent out from the first air guide port 21, that is, the wind is blown out from the first air guide port 21. In the second usage mode, first start the air guide body 1, the fan inside the air guide body 1 starts to blow air, then start the first lifting mechanism 4, the second lifting mechanism 5 is not started, the first lifting mechanism 4 drives the first air guide plate 2 to start to rise and fall along the axis of the air guide body 1, the second air guide plate 3 is covered on the air outlet 11, at this time the airflow can be sent out from the first air guide port 21 and the second air guide port 22, that is, the wind is blown out from the first air guide port 21 and the second air guide port 22. In the third usage mode, firstly, the air guide body 1 is activated, and the fan inside the air guide body 1 begins to deliver air. Then, the first lifting mechanism 4 and the second lifting mechanism 5 are activated. The first lifting mechanism 4 drives the first air guide plate 2 to rise and fall along the axial direction of the air guide body 1, and the second lifting mechanism 5 drives the second air guide plate 3 to rise and fall along the axial direction of the air guide body 1. A third air guide vent 31 is formed between the second air guide plate 3 and the air guide body 1. When the lifting heights of the first air guide plate 2 and the second air guide plate 3 are different, the first air guide... There will be a second air guide vent 22 between the air deflector 2 and the second air guide 3 due to the different lifting heights. At this time, the airflow can be sent out through the first air guide vent 21, the second air guide vent 22 and the third air guide vent 31. That is, the wind blows out from the first air guide vent 21, the second air guide vent 22 and the third air guide vent 31. When the lifting heights of the first air guide 2 and the second air guide 3 are the same, the airflow can be sent out through the first air guide vent 21 and the third air guide vent 31. That is, the wind blows out from the first air guide vent 21 and the third air guide vent 31.

[0028] In summary, when both the first air guide plate 2 and the second air guide plate 3 are close to the air guide body 1, that is, when neither the first air guide plate 2 nor the second air guide plate 3 has started to move axially, the air is blown out from the first air guide port 21. When the first lifting mechanism 4 moves the first air guide plate 2 away from the air guide body 1 and the lifting heights of the first air guide plate 2 and the second air guide plate 3 are different, the air from the air outlet 11 will be blown out from the first air guide port 21, the second air guide port 22, and the third air guide port 31. When the first lifting mechanism 4 moves the first air guide plate 2 away from the air guide body 1 and the lifting heights of the first air guide plate 2 and the second air guide plate 3 are the same, the air from the air outlet 11 will be blown out from the first air guide port 21 and the third air guide port 31.

[0029] Therefore, by controlling the lifting height of the first air guide plate 2 and the second air guide plate 3 through the first lifting mechanism 4 and the second lifting mechanism 5, the size and direction of the second air guide port 22 and the third air guide port 31 can be changed, thereby adjusting the air volume and direction blown out from the second air guide port 22 and the third air guide port 31. Secondly, the distance between the first air guide port 21 and the air outlet 11 can be changed, thereby adjusting the air speed and air volume blown out from the first air guide port 21. In this way, the air direction and air volume of the first air guide port 21, the second air guide port 22, and the third air guide port 31 can be controlled by controlling the lifting height and the difference in lifting height of the first air guide plate 2 and the second air guide plate 3, thus forming multiple air supply modes. Furthermore, the first lifting mechanism 4 and the second lifting mechanism 5 can also control the lifting speed of the first air guide plate 2 and the second air guide plate 3. Therefore, both the lifting height and the lifting speed of the first air guide plate 2 and the second air guide plate 3 can be adjusted, further enriching the air supply modes and enabling dynamic air supply.

[0030] When the fan body 1 is closed after use, the air outlet is stopped. The first lifting mechanism 4 controls the first air guide plate 2 to move closer to the fan body 1, and the second lifting mechanism 5 simultaneously controls the second air guide plate 3 to move closer to the fan body 1, so that the first air guide plate 2 and the second air guide plate 3 cover the air outlet 11, reducing the entry of dust and other debris.

[0031] It should be noted that the working status of the first lifting mechanism 4 and the second lifting mechanism 5 can be controlled by the control unit of the air conditioner indoor unit. The control unit can take many forms, such as a mobile remote control, a smart central control panel installed on the wall, or mobile phone software. The control unit sends operating information. A receiver is installed in the air guide body 1 to receive the operating signal sent by the control unit and send the operating signal to the first lifting mechanism 4 and the second lifting mechanism 5. The specific content of the control unit and the control part of the air conditioner indoor unit is existing technology and will not be described in detail here.

[0032] Compared to existing technologies, some air conditioner indoor units have fixed grilles or louvers at the air outlet, making the airflow direction unadjustable, resulting in a single air delivery mode and potentially causing the air to blow directly at the user. Some air conditioner indoor units use a single air guide vane, controlling the airflow direction by tilting or raising / lowering a single vane, but the air delivery modes remain monotonous and lack variety.

[0033] Therefore, in this embodiment, a first lifting mechanism 4 and a second lifting mechanism 5 are provided to control the lifting of the first air guide plate 2 and the second air guide plate 3 respectively, thereby forming a second air guide 22 and a third air guide 31 with side air outlet. By controlling the height and speed of the lifting of the first lifting mechanism 4 and the second lifting mechanism 5, the wind speed and direction of the wind blown out from the first air guide 21, the second air guide 22 and the third air guide 31 are controlled, thereby forming multiple air supply modes and reducing the situation of wind blowing directly on the user. The user can conveniently select different air supply modes on the control component according to their own needs, which improves the user experience.

[0034] Furthermore, the first lifting mechanism 4 includes a drive motor 41, a first transmission component 42, a second transmission component 43, and a lifting rod 44. The drive motor 41 and the first transmission component 42 are both mounted on the air guide body 1, and the first transmission component 42 is rotatably connected to the air guide body 1. The drive motor 41 is connected to the first transmission component 42 so that the drive motor 41 can drive the first transmission component 42 to rotate relative to the air guide body 1. The lifting rod 44 is connected to the first air guide plate 2, and the second transmission component 43 is connected to the lifting rod 44. The second transmission component 43 meshes with the first transmission component 42 so that the second transmission component 43 can rotate in conjunction with the first transmission component 42, thereby driving the lifting rod 44 to rise and fall, and in turn driving the first air guide plate 2 to rise and fall.

[0035] Furthermore, the first transmission component 42 includes a worm gear, and the second transmission component 43 includes a worm wheel. The worm wheel and the worm gear mesh and transmit power. The installation direction of the worm gear and the lifting rod 44 is the same as the lifting direction of the first air guide plate 2.

[0036] Therefore, when using the first lifting mechanism 4, the drive motor 41 is started, and the drive motor 41 drives the worm to rotate, so that the worm wheel meshing with the worm rotates along the spiral teeth extending from the outside of the worm, and then drives the lifting component to rise and fall, thereby causing the first air guide plate 2 connected to the lifting component to rise and fall. The structure is simple, the transmission process is short, and the structural stability is improved.

[0037] Furthermore, the helix angle of the spiral teeth extending from the outer side of the worm is smaller than the friction angle of the material itself. Thus, driven by the drive motor 41, the worm can rotate in a set direction, thereby driving the worm wheel to rotate. When the drive motor 41 stops, the worm stops as well. At this time, external factors such as wind or vibration may cause the worm wheel to experience a force opposite to the set direction, generating a reverse driving force on the worm. However, because the helix angle of the spiral teeth is smaller than the friction angle of the material itself, the static friction force on the meshing surface of the worm wheel and spiral teeth is greater than the reverse driving force, preventing the worm wheel from driving the worm in the opposite direction. This creates a self-locking function. Therefore, even if the airflow from the outlet 11 is high, the worm wheel and worm will rotate and transmit power in the set direction, ensuring stable lifting and lowering of the first air guide plate 2. This prevents noise and avoids the worm wheel being blown by the wind and generating a reverse driving force on the worm, which could cause frequent reverse transmission and lead to swaying and instability of the first air guide plate 2 during lifting and lowering, potentially resulting in noise. Therefore, the selection of worm gears and worms enables a self-locking function and improves structural stability.

[0038] It should be noted that the first transmission component 42 and the second transmission component 43 can also be two meshing gears to achieve transmission, namely the first gear and the second gear. The first gear is connected to the drive motor 41, and the second gear is connected to the lifting rod 44. When the drive motor 41 drives the first gear to rotate, the second gear is driven to rotate, thereby driving the lifting rod 44 to rise and fall, and in turn driving the first air guide plate 2 to rise and fall. The structural configuration of the first transmission component 42 and the second transmission component 43 can be selected according to actual needs.

[0039] To improve structural stability, the first lifting mechanism 4 also includes a mounting shell 45, which has a mounting cavity. The first transmission component 42, the second transmission component 43, the drive motor 41, and the lifting rod 44 are all located in the mounting cavity. The first transmission component 42 is rotatably connected to the mounting shell 45. The bottom of the mounting shell 45 is provided with a mounting seat 451. The lifting rod 44 passes through the bottom of the mounting shell 45 and connects to the mounting seat 451. The mounting seat 451 is connected to the first air guide plate 2. The top of the mounting shell 45 is also provided with a mounting plate 452, which is connected to the air guide body 1.

[0040] When assembling the mounting shell 45 with the air guide body 1, first pass the screw through the mounting plate 452 and the air guide body 1 to connect the mounting shell 45 with the air guide body 1. Then pass the screw through the mounting base 451 and the first air guide plate 2 to connect the mounting shell 45 with the first air guide plate 2 to complete the assembly. The steps are simple and the assembly is convenient.

[0041] When the first lifting mechanism 4 is used, the drive motor 41 starts, drives the first transmission component 42 to rotate, drives the second transmission component 43 to rotate, thereby driving the lifting component to rise and fall, so that the lifting component and the mounting shell 45 generate relative axial movement, and the mounting shell 45 and the air guide body 1 remain relatively stationary, thereby causing the first air guide plate 2 and the air guide body 1 to generate relative axial movement, that is, the first air guide plate 2 moves closer to or away from the air guide body 1.

[0042] After prolonged use, dust and debris may enter through the first air vent 21, the second air vent 22, and the third air vent 31, potentially interfering with the transmission of the first transmission component 42, the second transmission component 43, and the lifting rod 44, thus affecting the normal lifting and lowering of the first air guide plate 2. Therefore, by enclosing the first transmission component 42, the second transmission component 43, the drive motor 41, and the lifting rod 44 within the mounting shell 45, the influence of dust and debris can be avoided, and the stability of the structure's operation can be improved.

[0043] To simplify the overall structure, the second lifting mechanism 5 is made identical to the first lifting mechanism 4, thus their assembly and usage methods are the same. Of course, the second lifting mechanism 5 can also use a different structure than the first lifting mechanism 4, such as a cylinder and piston rod. The piston rod is connected to both the second air guide plate 3 and the air guide body 1, and the second air guide plate 3 is controlled by the cylinder driving the piston rod. The specific structural configuration of the second lifting mechanism 5 can be selected according to actual needs.

[0044] In addition, the first air guide plate 2 is provided with a first guide part 23, and the corresponding second air guide plate 3 is provided with a second guide part 32. The first guide part 23 is matched with the second air guide 22, and the second guide part 32 is matched with the third air guide 31.

[0045] Furthermore, the first guide portion 23 includes a first arc surface, and the second guide portion 32 includes a second arc surface.

[0046] When the first lifting mechanism 4 and the second lifting mechanism 5 are in operation and the lifting heights of the first air guide plate 2 and the second air guide plate 3 are different, the air from the air outlet 11 is blown out from the first air guide port 21, the second air guide port 22 and the third air guide port 31. The first arc surface and the second arc surface avoid the collision between the air and the flat air guide port, thereby reducing wind resistance. This allows the air to blow out gently and smoothly, and also reduces the noise of the air supply. This makes the air blown out from the second air guide port 22 and the third air guide port 31 tilted, gentle, smooth and quiet.

[0047] To further improve structural stability, a first guide and a second guide are provided. The first guide is provided on the first air guide plate 2 and the air guide body 1, and the second guide is provided on the second air guide plate 3 and the air guide body 1.

[0048] Furthermore, the first guide member includes a first guide hole and a first guide rod 24. Correspondingly, the second guide member includes a second guide hole and a second guide rod 33. The first guide hole and the second guide hole are disposed in the air guide body 1, the first guide rod 24 is disposed in the first air guide plate 2, and the second guide rod 33 is disposed in the second air guide plate 3. The first guide rod 24 passes through the first guide hole, and the second guide rod 33 passes through the second guide hole.

[0049] When the first guide plate 2 and the second guide plate 3 rise and fall, the first guide rod 24 always rises and falls within the first guide hole, and the second guide rod 33 also always rises and falls within the second guide hole. In this way, the first guide hole restricts the first guide rod 24 from radial movement, and the second guide hole also restricts the second guide rod 33 from radial movement. This restricts the first guide plate 2 and the second guide plate 3 to move axially along the air guide body 1, preventing deviation of their rising and falling trajectories. Therefore, the design of the first and second guide components restricts the movement trajectory of the first guide plate 2 and the second guide plate 3, thereby improving the structural operational stability.

[0050] In addition, the first air guide plate 2 is provided with an air guide net 25, which covers the first air guide opening 21. The air guide net 25 includes multiple regularly interwoven air guide strips, which together form multiple air guide intervals.

[0051] When in use, the air guide body 1 is started, causing air to be blown out from the air outlet 11, which in turn blows the air out from the air guide net 25 covering the first air guide 21. The multiple air guide strips included in the air guide net 25 not only refine the airflow and make the airflow blown out evenly from the air guide interval, but also reduce the entry of dust and other foreign objects into the first air guide 21, which would affect the normal operation of other components inside the air guide body 1. Therefore, the air guide net 25 can optimize the airflow and block foreign objects from entering, thereby improving the structural stability.

[0052] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
