Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically providing an indoor air conditioning unit and an air conditioner. Background Technology

[0002] The air deflector of a traditional split-type air conditioner indoor unit is a core component for airflow guidance, and its functional design directly affects the air delivery range, airflow uniformity, and user comfort experience.

[0003] In some related technologies, wall-mounted air conditioners commonly employ a single-layer air guide plate structure. During operation, this air guide plate primarily serves to roughly guide the direction of airflow. For example, by swinging the air guide plate up and down or left and right, the angle of the airflow can be adjusted within a certain range, achieving relatively broad airflow coverage. However, because its air guiding method is relatively crude, it can only adjust the overall airflow direction of the air conditioner and cannot flexibly adjust the local airflow, resulting in some users not achieving an ideal comfort experience when using the air conditioner.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] This application aims to solve the aforementioned technical problem, namely, to address the issue that the existing air guide vanes of indoor air conditioning units cannot meet users' needs for refined airflow due to their imprecise airflow guidance and inability to be locally adjusted.

[0010] A first driving device is connected to the first rotating shaft and the second rotating shaft respectively. The first rotating shaft and the second rotating shaft are both located outside the air outlet, so that the air outlet path can be changed when the driving device drives the first rotating shaft and the second rotating shaft to rotate relative to each other.

[0011] Optionally, the first and second rotating shafts are positioned close to each other to block airflow from passing through the gap between the first and second rotating shafts.

[0012] Optionally, the indoor unit of the air conditioner further includes:

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] Please refer to Figure 1 The present application provides an embodiment of an air conditioning indoor unit 1, which aims to achieve refined airflow by improving the air guiding structure at the air outlet 101.

[0037] Specifically, a first air guide assembly and a second air guide assembly are arranged side by side at the air outlet 101 of the housing 10 of the air conditioner indoor unit 1. The first air guide assembly includes a first rotating shaft 111 fixedly mounted on the housing 10 and a first air guide plate 112 mounted on the first rotating shaft 111. The second air guide assembly includes a second rotating shaft 121 fixedly mounted on the housing 10 and a second air guide plate 122 mounted on the second rotating shaft 121, wherein the second rotating shaft 121 is arranged parallel to the first rotating shaft 111.

[0038] Furthermore, to enable the independent operation of these two air guiding components, the indoor unit 1 of the air conditioner is also equipped with a first driving device. This first driving device can drive the first rotating shaft 111 and the second rotating shaft 121 to rotate independently, thereby driving them to rotate relative to each other. As these two shafts rotate relative to each other, the first air guide plate 112 and the second air guide plate 122 connected to them will also rotate relative to each other. Compared to a linked air guiding structure, this structure, where the air guide plates rotate independently, can not only adjust the air outlet direction at the air outlet 101 but also adjust the air outlet area, thus enabling flexible adjustment of the air outlet path to meet the usage requirements of different scenarios.

[0039] In one embodiment, the first driving device includes a first driving component that is drivenly connected to a first rotating shaft 111; and a second driving component that is drivenly connected to a second rotating shaft 121.

[0040] In one feasible implementation, the first drive assembly and the second drive assembly are each equipped with an independent motor and crank-rocker assembly. Taking the first drive assembly as an example, the crank-rocker assembly includes a crank, a rocker arm, and a connecting rod. The first end of the crank and the first end of the rocker arm are respectively hinged to the two ends of the connecting rod. The second end of the crank is connected to the output end of the motor, and the second end of the rocker arm is connected to the first rotating shaft 111. When the motor starts running, it drives the crank to perform a circular motion. With the circular motion of the crank, the rocker arm will oscillate through the transmission of the connecting rod, thereby driving the first rotating shaft 111 to rotate, thus causing the first air guide plate 112 to rotate. The structure of the second drive assembly is similar to that of the first drive assembly, and will not be described in detail here.

[0041] In a preferred embodiment, the first drive assembly includes a first driver, the output of which is connected to a first rotating shaft 111; the second drive assembly includes a second driver, the output of which is connected to a second rotating shaft 121. The first and second drivers are preferably micro stepper motors. Micro stepper motors feature discrete motion control and precise angular displacement output. This motor achieves high reliability and fast response under open-loop control, while its miniaturized design makes it compact, low-power, and suitable for miniaturized transmission mechanisms.

[0042] In the air conditioning air guide structure, two micro stepper motors can independently drive the first air guide plate 112 and the second air guide plate 122. By finely adjusting the angle of the two air guide plates, synchronous action can be achieved to expand the air delivery range, and differentiated angle combinations can be formed to control the airflow diffusion pattern.

[0043] In one embodiment, the first rotating shaft 111 and the second rotating shaft 121 are disposed adjacent to each other and connected to the housing 10 via a connecting bracket 13. Specifically, the indoor unit 1 of the air conditioner is provided with a connecting bracket 13, which is connected to the housing 10 and extends outward toward the air outlet 101. The first rotating shaft 111 and the second rotating shaft 121 are mounted on the connecting bracket 13. The first rotating shaft 111 is close to the air outlet 101, while the second rotating shaft 121 is away from the air outlet 101. The connecting bracket 13 not only supports the rotating shafts but also effectively prevents airflow from passing through the gap between the first rotating shaft 111 and the second rotating shaft 121.

[0044] In this way, the first air guide plate 112 and the second air guide plate 122 form a hinge-like structure, allowing for multi-angle fine-tuning of the air outlet direction through their relative rotation. This design enables the air conditioner to better meet the needs of different scenarios, improving the accuracy and comfort of indoor air conditioning.

[0045] In one embodiment, a third air guide component is further provided at the air outlet 101, and the third air guide component is arranged at intervals from the first air guide component and the second air guide component along the height direction of the air outlet 101. The third air guide component can rotate independently under the drive of the second driving device.

[0046] Specifically, the third air guide assembly consists of a third rotating shaft 131 and a third air guide plate 132 connected thereto. The second drive device drives the third rotating shaft 131 to rotate, thereby causing the third air guide plate 132 to rotate flexibly. In this way, the third air guide plate 132 can cooperate with the first air guide plate 112 and the second air guide plate 122 to adjust the air outlet area and air outlet direction at the air outlet 101, further improving the flexibility of the air outlet 101's air outlet mode.

[0047] refer to Figure 1 Taking the third air guide component located near the upper edge of the air outlet 101, and the first and second air guide components located near the lower edge of the air outlet 101 as an example, the third air guide plate 132 divides the air outlet 101 into an upper air outlet area near the upper edge and a lower air outlet area near the lower edge. The first and second air guide components are located in the lower air outlet area, so the air outlet direction and air outlet area of ​​the lower air outlet area can be adjusted.

[0048] The following section will explain how the air guide structure provided in this embodiment achieves multiple air outlet modes, using specific air outlet modes as examples.

[0049] Combination Figure 2 The structure shown in the figure indicates the airflow direction. When the user needs uniform airflow, the airflow mode can be adjusted by performing the following operations through the control system.

[0050] First, the first driving device drives the first air guide plate 112 and the second air guide plate 122 to approach 180 degrees. At this point, the two work together to form a continuous and extended planar airflow guiding structure. At the same time, the second driving device controls the third air guide plate 132 to rotate to a position that is nearly parallel to the first air guide plate 112 and the second air guide plate 122. This allows the third air guide plate 132 to cooperate with the first air guide plate 112 and the second air guide plate 122 to divide the air outlet 101 into three independent air outlet channels. The overall coverage area of ​​the planar airflow guiding structure of the first air guide plate 112 and the second air guide plate 122 exceeds the projection range of the third air guide plate 132, which is equivalent to extending the air outlet channel.

[0051] This extended air outlet channel can, on the one hand, reduce the diffusion range of the air after leaving the air outlet 101, allowing the air to be blown more concentrated in a specific direction, thus improving the directionality of the air outlet; on the other hand, by extending the airflow path, the airflow within the channel is more stable, reducing the generation of turbulence, thereby making the final blown air more uniform and gentle.

[0052] Combination Figure 3 The structure shown in the diagram indicates the direction of airflow. When users do not want the air to blow out directly, but also want a larger air volume or more even airflow, they can use the intelligent control system to make precise adjustments to the air conditioner's airflow mode as follows.

[0053] First, the second drive device is controlled to raise the third air guide plate 132 to a suitable angle. Then, the position of the second air guide plate 122 is adjusted so that it is raised to a certain angle and forms an air outlet gap with the third air guide plate 132. The position of the first air guide plate 112 is adjusted so that it is tilted downward to a certain angle and forms an air outlet gap with the lower edge of the air outlet 101. Through this adjustment method, the air outlet 101 can achieve multi-channel air outlet and improve the uniformity of air outlet.

[0054] Combination Figure 4 The structure shown in the figure indicates the direction of airflow. When the user does not need the air to be blown out directly, the air outlet mode can be adjusted by performing the following operations through the control system.

[0055] First, the second drive device is controlled to raise the third air guide plate 132 to a suitable angle. Then, the position of the second air guide plate 122 is adjusted so that one end of the second air guide plate 122 is tightly abutted against the third air guide plate 132. This abutting state effectively closes the intermediate air outlet channel that was originally located between the first air guide plate 112, the second air guide plate 122 and the third air guide plate 132, thereby preventing airflow from blowing directly forward from this channel.

[0056] Simultaneously, the angle of the first air guide plate 112 is adjusted so that it tilts downwards. When airflow exits from the air outlet 101, because the middle air outlet channel is closed, the airflow will flow along the tilted first air guide plate 112 and be guided to the lower rear of the air outlet 101. This design allows the air conditioner to avoid blowing directly on people, instead entering the indoor space in a gentler, diffused manner, providing users with a more comfortable experience, especially suitable for people who are sensitive to direct airflow or for specific usage environments.

[0057] The above content uses several methods of adjusting the relationship between the first, second, and third air guide components as examples to illustrate in detail the implementation process of different air outlet modes. Its purpose is to demonstrate that the air guide structure involved in this embodiment possesses the characteristic of refined air outlet. By flexibly adjusting the relative positions and angles between the various air guide components, key parameters such as the direction of airflow, air volume, and uniformity of airflow can be precisely controlled, thereby achieving diverse and refined air outlet modes to meet the specific needs of different users for comfortable airflow in different scenarios.

[0058] In one embodiment, to further improve the airflow effect, a first air guide groove 1120 is provided on the first air guide plate 112, and a second air guide groove 1220 is provided on the second air guide plate 122. When the airflow passes through the air guide groove, the groove wall will divide the airflow, dispersing the originally concentrated airflow into multiple smaller airflow bundles, avoiding situations where the local wind force is too strong or too weak. Therefore, the air in the entire space can be evenly circulated, improving people's comfort.

[0059] Furthermore, the first air guide slot 1120 and the second air guide slot 1220 are arranged in an alternating manner. This alternating arrangement allows the airflow passing through the air guide plate to form a more complex and orderly flow path when passing through the air guide slots. On the one hand, it can further disperse the airflow, making the airflow more uniform; on the other hand, it can also change the direction of the airflow to a certain extent, thereby achieving more precise airflow control to adapt to different usage scenarios and user needs.

[0060] In one embodiment, both the first air guide plate 112 and the second air guide plate 122 are designed as arc-shaped plates. Compared with the traditional flat plate structure, the unique shape of the arc-shaped plate can better guide the flow of air, so that the airflow flows smoothly along the arc surface when passing through the air guide plate, making the airflow softer and more natural, and creating a more comfortable user experience.

[0061] This application also provides an air conditioner, including the air conditioner indoor unit 1 as described above. Since the air conditioner indoor unit 1 has the above features and advantages, the air conditioner also has the above advantages, which will not be repeated here.

[0062] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
