[0048] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment shall be considered part of the specification.

[0049] The dimensions of the various parts shown in the accompanying drawings are not drawn to actual scale. Common structural elements or elements of the same kind are given the same reference numerals in the various drawings, and repeated descriptions of them are omitted where appropriate.

[0050] See Figures 1 to 3 This utility model provides an air duct conversion assembly 100, including a first disc 1, a second disc 2, a first air guide 3, and a second air guide 4. The second disc 2 is arranged at a distance from the first disc 1. One end of the first air guide 3 is fixedly connected to the first disc 1, and the other end of the first air guide 3 is fixedly connected to the second disc 2. The second air guide 4 is provided with a plurality of ventilation holes 41; the second air guide 4 is installed between the first disc 1 and the second disc 2, and the second air guide 4 is configured to be rotatable relative to the first disc 1 and the second disc 2.

[0051] The first disc 1 and the second disc 2 can be circular metal plates, arranged parallel to each other and spaced apart. The structure and size of the first disc 1 and the second disc 2 can be the same or different. In some embodiments of this utility model, the example is that both have the same structure and size.

[0052] The first air guide 3 serves to connect the first disc 1 and the second disc 2, and also seals the first air outlet 21 or the second air outlet 22 (described later) as the entire air duct conversion assembly rotates. The structure of the first air guide 3 matches the structure at the first air outlet 21 and the second air outlet 22 to improve the sealing performance of the sealing position when sealing the first air outlet 21 and the second air outlet 22. The first air guide 3 is fixedly connected to the edge of the first disc 1 and the edge of the second disc 2, specifically by welding or bolting. The structure formed by the first disc 1, the second disc 2, and the first air guide 3 is mostly empty. The width of the first air guide 3 is relatively narrow, which allows for a fixed connection between the first disc 1 and the second disc 2 while ensuring a sufficiently large air intake area for the air duct conversion assembly 100.

[0053] The second air guide 4 can be an arc-shaped plate, with the arc of the second air guide 4 being the same as the edge arc of the first plate. The second air guide 4 has multiple small-diameter (e.g., less than 1 cm) ventilation holes 41 distributed on it, with the spacing between the ventilation holes 41 less than the set value, for example, 2 cm. Optionally, the second air guide 4 can be an arc-shaped metal mesh plate, with the mesh holes being square, circular, hexagonal, or triangular holes with a side length of approximately 1 cm. The material of the second air guide 4 can be aluminum alloy or carbon fiber plate. Aluminum alloy can improve structural strength, while carbon fiber plate can reduce overall weight.

[0054] The second air guide 4 is rotatable relative to the first disc 1 and the second disc 2, with a rotation range of 360° or a set angle range. Rotation of the second air guide 4 adjusts the air outlet area of ​​the air duct conversion assembly 100, allowing air to pass through the ventilation holes 41 of the second air guide 4, achieving a small stream of airflow and improving comfort. Optionally, a first gear is provided on the edge of the second air guide 4, a motor is mounted on the first disc 1, and a second gear is mounted on the motor output shaft; the first and second gears mesh. Driving the second air guide 4 to rotate via the motor achieves automated air duct conversion, improving the automation level of air outlet adjustment. The second air guide 4 can be fixed in any position or allowed to swing within a certain range to achieve a sweeping effect. When the second air guide 4 rotates, the correspondence between the second air guide 4 and the edges of the first disc 1 and the second disc 2 changes, thereby achieving a conversion of airflow volume and direction.

[0055] In the above technical solution, the first disc 1 and the second disc 2 of the air duct conversion component 100 can rotate as a whole, which will drive the second air guide 4 to rotate synchronously. In addition, the second air guide 4 can also rotate relative to the first disc 1 and the second disc 2. Through the air duct conversion component 100, the air duct of the indoor unit can be flexibly adjusted to improve ventilation efficiency and increase the convenience of air outlet adjustment.

[0056] See also Figure 2 and Figure 3 In some embodiments, the air duct conversion assembly 100 further includes a first drive assembly 5, which is installed on the first disc 1 or the second disc 2 to drive the first disc 1 and the second disc 2 to rotate together.

[0057] The first drive assembly 5 can adopt a transmission form such as gear transmission or belt transmission. Optionally, the first drive assembly 5 includes a drive unit (not shown in the figure), a driving gear (not shown in the figure), and a driven gear. The drive unit is specifically, for example, a drive motor, and the output shaft of the drive motor is equipped with a driving gear, which meshes with the driven gear. The drive motor can specifically be a DC geared motor, which is mounted on the housing of the air distribution box 200 and supported by the air distribution box 200. The driven gear is fixedly connected to one of the first disc body 1 and the second disc body 2, which can be bolted or welded.

[0058] In other embodiments, there are two first drive components 5. The first disc 1 is fixedly connected to the driven gear of one of the first drive components 5, and the second disc 2 is fixedly connected to the driven gear of the other first drive component 5. Using two first drive components 5 to drive the first disc 1 and the second disc 2 to rotate provides more driving power and smoother, more reliable movement.

[0059] When the drive motor starts, its output shaft rotates, causing the driving gear on the output shaft to rotate, which in turn drives the driven gear to rotate. Since the driven gear is fixedly connected to the first disc 1, and the first disc 1 and the second disc 2 are fixedly connected through the first air guide 3, the first disc 1 and the second disc 2 rotate together around their respective central axes. The rotational speeds of the first disc 1 and the second disc 2 can be adjusted by the motor controller.

[0060] In the above technical solution, the first driving component 5 drives the first disc 1 and the second disc 2 to rotate together. Combined with the rotation of the second air guide component 4 itself, a more flexible and wider air duct conversion is achieved. In terms of technical effect, the ventilation efficiency is improved, which can meet the ventilation needs of different scenarios.

[0061] In some embodiments, the air duct conversion assembly 100 further includes a second drive assembly 6, which is disposed between the second air guide 4 and the first disc 1. Alternatively, the second drive assembly 6 is disposed between the second air guide 4 and the second disc 2. Alternatively, there may be two second drive assemblies 6, one of which is installed between the first disc and the second air guide 4, and the other is installed between the second disc 2 and the second air guide 4. Regardless of the method used, the second drive assembly 6 is used to drive the second air guide 4 to rotate relative to the first disc 1 and the second disc 2.

[0062] The second drive assembly 6 has three configurations: first, a single second drive assembly 6 is positioned between the second air guide 4 and the first disc 1; second, a single second drive assembly 6 is positioned between the second air guide 4 and the second disc 2; and third, two second drive assemblies 6 are configured, one positioned between the second air guide 4 and the first disc 1, and the other positioned between the second air guide 4 and the second disc 2. In all these configurations, the structure of the second drive assembly 6 can be identical.

[0063] In the first scenario, the second drive assembly 6 is installed between the second air guide 4 and the first disc 1, and the second drive assembly 6 employs gear meshing transmission. A stepper motor is fixedly mounted on the side of the first disc 1 facing the second disc 2 via a bracket, and the output shaft of the stepper motor is connected to a driving gear. The second air guide 4 is an arc-shaped nylon plate, and a driven gear is integrally formed at its end, with the driving gear meshing with the driven gear. When the stepper motor of the second drive assembly 6 operates, it drives the second air guide 4 to rotate via gear transmission, thereby improving the adjustment accuracy of the angle of the second air guide 4.

[0064] In the second scenario, taking the second drive assembly 6 positioned between the second air guide 4 and the second disc 2 as an example, the structure of the second drive assembly 6 can be the same as that of the first drive assembly 5, only smaller in size and model. The second drive assembly 6 can adopt a transmission form such as gear drive or belt drive. Of course, the second drive assembly 6 can also adopt a simpler structure, because the second air guide 4 is lightweight and easier to drive.

[0065] The drive motor, for example, is a DC geared motor for direct drive. The second disc 2 is a circular aluminum alloy plate. The DC geared motor is bolted to the side of the second disc 2 facing the first disc 1. The output shaft of the DC geared motor is rigidly connected to the end of the second air guide 4 via a coupling. When the DC geared motor of the second drive assembly 6 starts, the output shaft of the DC geared motor drives the second air guide 4 to rotate around the rotation center axis of the guide. The speed of the second air guide 4 can be adjusted by the DC geared motor controller, realizing precise angle control of the second air guide 4 relative to the first disc 1 and the second disc 2. The second drive assembly 6 adopts this implementation method, which has a short transmission path, a transmission efficiency of 95%, and can quickly respond to the needs of air duct conversion.

[0066] In the third scenario, there are two second drive components 6, installed between the first disc 1 and the second air guide 4, and between the second disc 2 and the second air guide 4, respectively. The second drive components 6 are driven by synchronous belts. The first disc 1 and the second disc 2 can be plastic discs, and the second air guide 4 is an arc-shaped mesh plate. One second drive component 6 is installed on the side of the first disc 1 facing the second disc 2, and another second drive component 6 is installed on the side of the second disc 2 facing the first disc 1.

[0067] The motor shaft of the servo motor installed inside the first disc 1 is connected to the first active synchronous pulley; the end of the second air guide 4 is fixed with the same specification first driven synchronous pulley, and the two are connected by a synchronous belt.

[0068] The motor shaft of the servo motor installed inside the second disc 2 is connected to the second active synchronous pulley; the other end of the second air guide 4 is fixed with a second driven synchronous pulley of the same specification, and the two are connected by a synchronous belt.

[0069] When the two second drive components 6 work synchronously, they drive the second air guide 4 to rotate through belt transmission. During the rotation, the two ends of the second air guide 4 are balanced by forces, with almost no wobble, and the rotation is more stable.

[0070] In the above embodiments, the ventilation holes 41 of the second air guide 4 are arranged in a row evenly. The second air guide 4 adopts a long strip-shaped arc plate, on which ventilation hole groups are arranged in a row evenly along the length direction. The arrangement of ventilation holes 41 in a row in the second air guide 4 makes the air in the air duct more evenly distributed.

[0071] In some embodiments, the second air guide 4 is configured as an arc-shaped plate, and the curvature of the second air guide 4 is the same as the edge curvature of the first disc 1. When the airflow passes through the ventilation holes 41 on the second air guide 4, the second air guide 4 plays a role in equalizing the airflow, so that the airflow is divided into streams of gentle breeze.

[0072] In some embodiments, the rotation center of the second air guide 4 is offset from the center of the first disc 1. Specifically, the rotation radius of the second air guide 4 is smaller than the radius of the first disc 1.

[0073] The second air guide 4 can be rotated to the edge of the first disc 1 and the second disc 2, or it can be rotated to a position closer to the inside of the first disc 1 and the second disc 2. As needed, by rotating the second air guide 4, the position of the second air guide 4 can be changed, so that the air passes through or does not pass through the ventilation hole 41 on the second air guide 4, so as to achieve a more flexible adjustment of the air outlet mode.

[0074] This utility model embodiment also provides an indoor unit, including the air duct conversion component 100 provided by any technical solution of this utility model.

[0075] like Figure 1 As shown, the indoor unit includes a fan assembly 300, a heat exchanger cavity 400, an air distribution box 200, and an electrical box assembly 500, wherein the electrical box is arranged on the front side of the heat exchanger cavity 400.

[0076] The fan component 300 includes a volute, a motor, and fan blades. At least the top, front, and rear sides are free of obstructions from the casing, improving the return air passage and heat exchange efficiency. When there are two or more fan blades, the motor is located closer to the electrical box. The air distribution box 200 contains a duct conversion assembly 100; rotation of this assembly allows for smoother upward and downward airflow from the unit.

[0077] In some embodiments, the indoor unit further includes an air distribution box 200, which includes a first air outlet 21 and a second air outlet 22; the air outlets 21 and 22 have different air outlet directions. A duct conversion assembly 100 is installed inside the air distribution box 200. The first air guide 3 of the duct conversion assembly 100 is configured to rotate and block one of the first air outlet 21 and the second air outlet 22. The first air outlet 21 and the second air outlet 22 are selectively connected, and the duct conversion assembly 100 serves to guide or equalize the airflow exiting through the first air outlet 21 and the second air outlet 22.

[0078] See Figure 1The indoor unit's air distribution box 200 has a box-shaped structure. A first air outlet 21 is located on the side of the air distribution box 200 away from the heat exchanger cavity, with the air outlet direction being horizontal. A second air outlet 22 is located on the bottom surface of the air distribution box 200, with the air outlet direction being vertically downward. The air duct conversion assembly 100 is installed inside the air distribution box 200, and the first plate 1 and the second plate 2 are rotatably mounted on the inner wall of the air distribution box 200.

[0079] In some embodiments, an air outlet foam 23 may be provided at the second air outlet 22. The air outlet foam 23 may be made of porous polyurethane foam or activated carbon composite foam. The air outlet foam 23 covers at least part of the inner wall surface of the second air outlet 22, and the end face of the air outlet foam 23 is flush with the edge of the second air outlet 22. The air outlet foam 23 may be installed by means of clips, adhesives, etc.

[0080] The porous structure of the vent foam 23 converts sound wave energy through air vibration and friction, significantly suppressing airflow disturbance noise, especially at the second air outlet 22. Furthermore, the vent foam 23 can intercept airborne particulate matter, reducing the amount of dust entering the room and lowering the probability of dust accumulation inside the duct unit. The vent foam 23 uses activated carbon composite foam, which also has the function of absorbing formaldehyde and odors, making it suitable for newly renovated spaces.

[0081] The heat exchanger cavity 400 houses a heat exchanger 401 and a drip tray 402. The heat exchanger cavity 400 is generally a rectangular metal shell with an air inlet on one side and an air outlet on the other. The heat exchanger 401 and drip tray 402 are fixed inside by a bracket. The heat exchanger 401 can be a finned tube structure or a microchannel heat exchanger. The heat exchanger 401 can be a V-type, U-type, or C-type heat exchanger, with its concave surface facing the fan component 300 and its convex surface facing the air duct conversion component 100. The drip tray 402 can be made of stainless steel or plastic, and is shallow in shape. It is fixed directly below the heat exchanger 401 by clips, with the edges folded upwards to prevent overflow. The heat exchanger 401 cools or heats the air through heat exchange between the refrigerant and the air. The drip tray 402 collects and drains the condensate, preventing water accumulation inside the cavity. The cooperation between heat exchanger 401 and water receiving tray 402 ensures efficient heat exchange inside the cavity and prevents liquid accumulation.

[0082] In the above technical solution, the air duct conversion component 100 is installed inside the air distribution box 200. Regardless of which of the first air outlet 21 or the second air outlet 22 of the air distribution box 200 is discharging air, the air duct conversion component 100 can achieve the function of guiding and equalizing airflow as needed, making the air outlet form more diverse and the functions more numerous.

[0083] Each of the first air outlet 21 and the second air outlet 22 can be matched with the first air guide 3. By rotating the first air guide 3 to different positions, one of the first air outlet 21 and the second air outlet 22 can be closed and the other can be opened.

[0084] In some embodiments, the indoor unit includes at least one of the following four operating modes:

[0085] See Figure 4 In the first mode, the first air outlet 21 is open, the second air outlet 22 is blocked and closed by the first air guide 3, and the second air guide 4 is rotated to be parallel to the air outlet direction of the indoor unit.

[0086] The first mode is the normal cooling mode, with the first air outlet 21 open, allowing the indoor unit to discharge air horizontally. The airflow sequence is as follows: air enters the fan, flows through the heat exchanger, and then exits through the first air outlet 21. The arc shape of the second air guide 4 is basically parallel to the air outlet direction, and the second air guide 4 acts as a guide, resulting in a larger airflow.

[0087] See Figure 5 In the second mode, the first air outlet 21 is open, the second air outlet 22 is blocked and closed by the fixed baffle, and the second air guide 4 is rotated to be perpendicular to the air outlet direction of the indoor unit to act as a baffle. Alternatively, the second air guide 4 is configured to be swingable and intersects with the air outlet direction of the indoor unit.

[0088] The second mode is the cooling mode, which is the operating mode of the cooling unit when the ambient temperature is close to the target cooling temperature or when the customer selects the silent mode. In this second mode, the first air outlet 21 is open, and the indoor unit can discharge air horizontally. The gas flow sequence is as follows: the incoming air reaches the fan, flows through the heat exchanger, and then some of the gas flows out of the first air outlet 21 after passing through the second air guide 4, while the remaining gas flows out directly through the first air outlet 21. The arc direction of the second air guide 4 is basically perpendicular to the air outlet direction. The second air guide 4 plays a role in equalizing the airflow, making the airflow softer and more uniform.

[0089] In the second mode, the position of the second air guide 4 can also be oscillating as needed. By driving the second air guide 4 to rotate back and forth within a set range, oscillation is achieved, serving as a guide and sweeping function. The ventilation hole 41 of the second air guide 4 remains basically aligned with the first air outlet 21. When the second air guide 4 oscillates, more air is evenly distributed by the second air guide 4, resulting in a more significant air distribution effect. The aforementioned second mode is based on the first mode. When the cooling temperature is close to the set temperature or when the customer selects the silent cooling mode, the angle of the second air guide 4 is rotated, changing the air outlet area of ​​the entire air duct conversion component 100, and allowing the air to pass through the ventilation hole 41 of the second air guide 4, achieving multiple small air streams and improving airflow comfort.

[0090] See Figure 6 In the third mode, the first air outlet 21 is blocked and closed by the first air guide 3, while the second air outlet 22 is opened. The second air guide 4 is rotated to a vertical position, basically parallel to the air outlet direction of the indoor unit, to guide the airflow.

[0091] The third mode is the heating mode, in which the second air outlet 22 is open, allowing the indoor unit to discharge air vertically downwards. The air flow sequence is as follows: air enters the fan, flows through the heat exchanger, and then exits through the second air outlet 22. The arc shape of the second air guide 4 is basically parallel to the air outlet direction, and the second air guide 4 plays a guiding role in this mode, resulting in a larger air volume.

[0092] See Figure 7 In the fourth mode, the first air outlet 21 is blocked and closed by the first air guide 3, and the second air outlet 22 is opened. The second air guide 4 is rotated to a horizontal position and is basically perpendicular to the air outlet direction of the indoor unit, or the second air guide 4 is constructed to be swingable and intersects with the air outlet direction of the indoor unit.

[0093] In the fourth mode, the second air outlet 22 opens, allowing the indoor unit to discharge air vertically downwards. The airflow sequence is as follows: incoming air reaches the fan, flows through the heat exchanger, and then some air passes through the second air guide 4 before exiting from the second air outlet 22, while the remaining air flows directly out through the second air outlet 22. The arc shape of the second air guide 4 is basically perpendicular to the airflow direction, and the second air guide 4 plays a role in equalizing the airflow, resulting in a softer and more uniform airflow.

[0094] In the fourth mode, the position of the second air guide 4 can also be oscillating as needed. This oscillation is achieved by driving the second air guide 4 to rotate back and forth within a set range. The ventilation holes 41 of the second air guide 4 remain basically aligned with the second air outlet 22. When the second air guide 4 oscillates, more air is evenly distributed within it, resulting in a more pronounced airflow equalization effect. This fourth mode, based on the third mode, is the operating mode of the air conditioner when heating is about to reach the set temperature or when the customer selects a silent mode. Rotating the angle of the second air guide 4 changes the air outlet area of ​​the entire air duct conversion assembly 100, and allows the air to pass through the ventilation holes 41 of the second air guide 4, achieving multiple small air streams and improving airflow comfort.

[0095] Because the indoor unit can simultaneously offer the four airflow modes mentioned above, users can quickly switch between them according to their actual needs: Under normal cooling conditions, the first mode enables long-distance centralized airflow to quickly adjust the overall temperature; under cooling conditions where the temperature is close to the target temperature, the second mode's oscillation function ensures uniform airflow, preventing excessive local temperature differences. Under normal heating conditions, the third mode uses directional airflow to reduce energy loss; and under heating conditions where the temperature is close to the target temperature, the fourth mode improves overall comfort. This diverse airflow method greatly enhances the flexibility of the indoor unit, adapting to a wider range of ventilation scenarios. Simultaneously, the combination of high airflow and uniform airflow allows the indoor unit to meet rapid adjustment while keeping the wind speed difference between points in the space within a small range, balancing the need for both large and uniform airflow, significantly improving the user experience.
