[0041] As a specific embodiment, this embodiment provides an air conditioner indoor unit 1, such as Figures 1 to 3 The air conditioner indoor unit 1 includes a sensing device 30 and at least two sets of swing blade assemblies 10. The sensing device 30 is used to determine whether there is a person in the area facing the air outlet 20 of the air conditioner indoor unit 1. The at least two sets of swing blade assemblies 10 are located in different areas of the air outlet 20. When a person is facing a certain area of the air outlet 20, the swing blade assembly 10 in that area switches to a wind-spinning mode.

[0042] The basic type of sensing device 30 can be selected as needed. For example, the sensing device 30 can be one of infrared, imaging, ultrasonic, and Doppler sensors, or a combination thereof. The imaging device can be wide-angle, or it can include a rotating scanning head to obtain information about the area facing the air outlet 20, which is used to determine whether there is anyone in the area facing the air outlet 20.

[0043] The specific type of the swing blade assembly 10 can be selected as needed. The swing blade assembly 10 is used to disrupt the original airflow direction, preventing the airflow from the air outlet 20 from blowing directly at people located in the area directly opposite the air outlet 20. Taking a wall-mounted air conditioner as an example, the original air guide assembly of the wall-mounted air conditioner can swing up and down or swing up and down to a certain angle. The swing blade assembly 10 can guide air left and right, or swing up and down. When the swing blade assembly 10 is independently controlled to guide air, its swing direction, frequency, or angle is inconsistent with that of the air guide assembly, thereby disrupting the original airflow direction and preventing the airflow from the air outlet 20 from blowing directly at people located in the area directly opposite the air outlet 20.

[0044] In summary, when the sensing device 30 senses that a person is located in the area facing the air outlet 20, the swing blade assembly 10 in this area switches to the wind disturbance mode to avoid the discomfort caused by the wind blowing directly towards the person.

[0045] In some other embodiments, such as Figures 1 to 3 As shown, the air conditioner indoor unit 1 is a wall-mounted air conditioner indoor unit 1, and the air outlet 20 is in the shape of a long strip. The air outlet 20 is divided into at least two areas along its length direction; a group of swing blade components 10 is set in each area.

[0046] The size and number of the regions can be selected as needed. In this embodiment, Figures 1 to 3 As shown, the air outlet 20 is divided into two equal areas along its length: a left area and a right area. There are also two sets of pendulum blade assemblies 10: one set is located in the right area, and the other set is located in the left area. In other words, the two sets of pendulum blade assemblies 10 are distributed on the left and right sides of the air outlet 20, respectively, and together, they cover the entire area of the air outlet 20.

[0047] In other embodiments, when the sensing device 30 determines that no one is in the area directly facing the air outlet 20, at least two sets of the swing blade assemblies 10 switch to the air guide mode. In this embodiment, the swing blade assemblies 10 have both an air guide mode and a wind scrambling mode. When the area directly facing the air outlet 20 is occupied, the swing blade assemblies 10 switch to the wind scrambling mode to prevent the cold air from directly blowing on the person. When the area directly facing the air outlet 20 is unoccupied, the swing blade assemblies 10 switch to the air guide mode, which facilitates rapid temperature uniformity throughout the room.

[0048] Specifically, if Figures 1 to 3 As shown, when there are two groups of swing blade assemblies 10, each group of swing blade assemblies 10 is independently controlled, that is, the modes of the two groups of swing blade assemblies 10 can be the same or different. As a more specific embodiment, Figures 1 to 3 As shown, when a person is directly facing the left air outlet 20, the left swing blade assembly 10 is adjusted to wind-disturbing mode, while the right swing blade assembly 10 is adjusted to wind-guiding mode. This prevents the air from the left air outlet 20 from blowing directly at the person and makes the air flow from the left side softer. When the right swing blade 100 is in wind-guiding mode, it guides the air to the left and right as much as possible, quickly evens out the indoor temperature and diversifies the air supply.

[0049] Therefore, the swing blade assembly 10 has a wind guide mode and a wind disturbance mode, and the two groups of swing blades 100 are controlled separately. This not only prevents the air outlet 20 from blowing directly towards people, making the air outlet softer, but also makes the indoor temperature quickly uniform and the air supply form diversified.

[0050] In some other embodiments, the sensing device 30 includes a sensing head, which is configured to scan the area directly facing the air outlet 20 to detect whether there is anyone in the area directly facing the air outlet 20 .

[0051] In some other embodiments, such as Figures 1 to 8As shown, each set of pendulum blade assemblies 10 includes a plurality of pendulum blades 100, each pendulum blade 100 includes two sub-pendulum blades 110, each sub-pendulum blade 110 is hollowed out, and the hollow shapes of the two sub-pendulum blades 110 complement each other, and the two sub-pendulum blades 110 are configured to swing individually or synchronously. Specifically, when the pendulum blade 100 is configured in the wind-guiding mode, the hollow portions 1111 of the two sub-pendulum blades 110 are staggered and spliced so that the two sub-pendulum blades 110 form an integral pendulum blade 100, and the two sub-pendulum blades 110 swing synchronously so that the pendulum blade 100 swings or swings to a preset angle. When the pendulum blade 100 is configured in the wind-disturbing mode, the two sub-pendulum blades 110 pass through each other through the hollow portions 1111 and swing individually or swing to a preset angle.

[0052] As can be seen, when the pendulum assembly 10 is in the wind-guiding mode, the hollow portions 1111 of the two sub-blades 110 of each pendulum blade 100 are staggered and spliced together, forming the two sub-blades 110 into a single, integrated pendulum blade 100. This allows the pendulum blade 100 to guide a relatively large amount of air, which helps to quickly even out the indoor temperature. When the pendulum assembly 10 is in the wind-spinning mode, the two sub-blades 110 of each pendulum blade 100 pass through each other through the hollow portions 1111 and swing independently or to a preset angle, making the airflow at that location softer and preventing direct cold wind.

[0053] The shape of the hollowed-out sub-leaves 110 can be selected as needed, and the hollowed-out parts 1111 of the two sub-leaves 110 can be staggered and spliced to form an integral leave 100. Figures 4 to 8 As shown, the hollow shapes of the two sub-oscillating leaves 110 are comb-shaped, that is, the hollow shapes of the two sub-oscillating leaves 110 are long strips arranged in sequence, such as Figures 4 to 8 As shown, the two sub-oscillating blades 110 are hollowed out in a horizontal strip-like shape. Obviously, the hollowed-out shape of the hollow portion 1111 is merely exemplary and not exclusive. For example, the hollowed-out shape of the two sub-oscillating blades 110 can also be a vertical strip-like shape or other shapes. The horizontal strip-like shape of the sub-oscillating blades 110 facilitates directing air to the left and right sides (laterally) when the sub-oscillating blades 110 swing. While the sub-oscillating blades 110 soften the airflow, they also contribute to uniform indoor temperature.

[0054] In this embodiment, there are two sub-oscillating blades 110, which are arranged from top to bottom and staggered at their contact points to form a sub-oscillating blade 100. Obviously, the number of sub-oscillating blades 110 can also be multiple, with multiple sub-oscillating blades 110 arranged sequentially from top to bottom, and two adjacent sub-oscillating blades 110 staggered to form a complete oscillating blade 100. For the reasons mentioned above, the shape and number of sub-oscillating blades 110 are optional.

[0055] The hollow shape of the sub-pendulum blades 110 is complementary, and there are many advantages in splicing multiple sub-pendulum blades 110 to form a pendulum blade 100. For example, when the sub-pendulum blades 110 are spliced into a pendulum blade 100, the area of the pendulum blade 100 is relatively large, and the amount of air guided is relatively large. At this time, the pendulum blade 100 is in the air guiding mode, which can quickly make the indoor temperature uniform. When the two sub-pendulum blades 110 of the pendulum blade 100 guide the air separately, the sub-pendulum blade 110 is hollow, and the wind can be blown out from the hollow, and the wind is softer, avoiding the wind from the air outlet 20 blowing directly on people. Because the sub-pendulum blades 110 are staggered, the page of a single sub-pendulum blade 110 is also relatively large, and the air guiding range of a single sub-pendulum blade 110 is also relatively wide, making the air outlet 20 relatively soft.

[0056] In other embodiments, each sub-oscillating blade 110 further includes a main plate 111 having a hollowed-out portion 1111 and a rotating sleeve 112. The main plate 111 includes a hollowed-out portion 1111. The rotating sleeve 112 is formed at the edge of the main plate 111 and extends outward. Each set of oscillating blade assemblies 10 further includes multiple rotating shafts 200, which are provided in a one-to-one correspondence with the multiple oscillating blades 100. The rotating sleeve 112 of the sub-oscillating blade 110 of each oscillating blade 100 is sequentially mounted on the rotating shaft 200.

[0057] In this embodiment, the main plate 111 is planar and has a hollow portion 1111. When two sub-swing blades 110 are staggered and spliced to form a single swing blade 100, the two main plates 111 are staggered and spliced to form a single main plate 111. In this case, the two main plates 111 are located on the same plane. Obviously, this is merely exemplary, and the shape of the main plate 111 is not exclusive.

[0058] Multiple rotating shafts 200 correspond one-to-one to multiple pendulum blades 100, that is, each pendulum blade 100 is configured with a rotating shaft 200, and the sub-pendulum blades 110 of each pendulum blade 100 are all sleeved on the rotating shaft 200 through the rotating shaft sleeve 112. The rotating shaft 200 strings the sub-pendulum blades 110 together along the axial direction of the rotating shaft 200 to form a pendulum blade 100.

[0059] The rotating shaft sleeves 112 of the sub-pendulum blades 110 of each pendulum blade 100 are sequentially sleeved on the rotating shaft 200. The sub-pendulum blades 110 are arranged from top to bottom on the rotating shaft. For ease of distinction, the sub-pendulum blades 110 of each pendulum blade 100 are respectively referred to as upper sub-pendulum blades 110 and lower sub-pendulum blades 110 from top to bottom. The upper sub-pendulum blades 110 of each group of pendulum blades 100 are on the same horizontal line, that is, the upper sub-pendulum blades 110 of each group of pendulum blades 100 are located in a row. The lower sub-pendulum blades 110 of each group of pendulum blades 100 are on the same horizontal line, that is, the lower sub-pendulum blades 110 of each group of pendulum blades 100 are located in a row.

[0060] This structure of the pendulum assembly 10 is simple and is conducive to the control of the upper row of sub-pendulum blades 110, the lower row of sub-pendulum blades 110 and the pendulum blades 100. For example, the pendulum assembly 10 also includes a driving device, which is used to drive the rotation of the pendulum blades 100, the upper row of sub-pendulum blades 110 and the lower row of sub-pendulum blades 110. The driving device includes two chains, and the extension direction of the two chains is perpendicular to the rotating shaft 200. The two chains are arranged in sequence along the axial direction of the rotating shaft 200, that is, the two chains are arranged from top to bottom along the vertical direction, and the upper chain is used to control the rotation of the upper row of sub-pendulum blades 110, and the lower chain is used to control the rotation of the lower row of sub-pendulum blades 110. This control method has a simple structure and is easy to achieve synchronous control.

[0061] In some other embodiments, each group of sub-swing blade 110 assemblies 10 further includes a positioning sleeve 500, which is sleeved on the rotating shaft 200; each rotating sleeve 112 is engaged with a positioning sleeve 500. When the driving device drives the rotating sleeve 112 to rotate, the rotating device drives the sub-swing blade 110 to rotate, and the rotating sleeve 112 of the sub-swing blade 110 drives the positioning sleeve 500 to rotate. When the sub-swing blade 110 or the swing blade 100 rotates to a preset angle to guide the air, when the air outlet 20 blows toward the sub-swing blade 110, the air outlet will generate a certain impact force on the sub-swing blade 110. The impact force of the air outlet may drive the swing blade 100 to rotate, and the impact force of the air outlet in turn drives the rotating sleeve 112 to rotate. When the impact force of the air outlet 20 drives the swing blade 100 to rotate, the swing blade 100 will deviate from the preset angle, and the swing blade 100 will no longer guide the air at the preset angle. In other words, the impact force of the outgoing air will affect the air guidance at the preset angle. The positioning sleeve 500 is engaged with the rotating sleeve 112 to prevent the impact force of the outgoing air from causing the swing blade 100 to deviate from the preset angle.

[0062] In some other embodiments, each sub-swing blade 110 further includes a connecting portion 113, which is disposed on the side of the rotating sleeve 112 opposite to the main plate 111 and extends in a direction away from the main body. That is, the connecting portion 113 and the main plate 111 are both connected to the rotating sleeve 112, and the connecting portion 113 and the main plate 111 are oriented in opposite directions. As a specific embodiment, Figures 1 to 8 As shown, the main plate 111 and the connecting portion 113 are both connected to the side wall of the rotating sleeve, with the main plate 111 and the connecting portion 113 facing away from each other. That is, the main plate 111 is located in front of the rotating sleeve 112, and the connecting portion 113 is located behind the rotating sleeve 112. The main plate 111, rotating sleeve 112, and connecting portion 113 are arranged in order from front to back. Alternatively, it can be understood that the main plate 111 and the connecting portion 113 face opposite directions, with the main plate 111 facing forward and the connecting portion 113 facing backward.

[0063] The specific structure of the connecting portion 113 can be selected as needed, as long as the connecting portion 113 can be connected to the connecting rod 300. In this embodiment, the connecting rod 300 has an arc-shaped notch, which faces the connecting portion 113. The connecting portion 113 includes a cylindrical engaging block that is received in the notch to connect the connecting portion 113 to the connecting rod 300.

[0064] The pendulum blade assembly 10 also includes two connecting rods 300, which are perpendicular to the rotating shaft 200. The two connecting rods 300 are arranged in sequence along the axial direction of the rotating shaft 200. The two connecting rods 300 are connected to the connecting parts 113 of the two sub-pendulum blades 110 in a one-to-one correspondence, and are used to drive the sub-pendulum blades 110 to rotate relative to the rotating shaft 200.

[0065] The two connecting rods 300 are perpendicular to the rotating shaft 200. As a specific embodiment, Figures 1 to 4 As shown, when the shaft 200 is arranged vertically, the connecting rod 300 is arranged horizontally. The two connecting rods 300 are arranged in sequence along the axial direction of the shaft 200, as shown in FIG. Figures 1 to 4 As shown, when the rotating shaft 200 is vertically arranged, the two connecting rods 300 are arranged in sequence from top to bottom. For convenience, the connecting rod 300 located on top is called the upper connecting rod 300, and the connecting rod 300 located below is called the lower connecting rod 300.

[0066] The two connecting rods 300 are connected to the connection parts 113 of the two sub-swing blades 110 in a one-to-one correspondence, as shown in FIG. Figures 1 to 4 As shown, the upper connecting rod 300 is connected one by one with the upper sub-swing blades 110 in the upper row, and the lower connecting rod 300 is connected one by one with the lower sub-swing blades 110 in the lower row. Figures 1 to 4 As shown, that is, when the upper connecting rod 300 moves left and right, the upper connecting rod 300 drives the upper row of sub-swing leaves 110 to rotate left and right. When the lower connecting rod 300 moves in a direction perpendicular to the rotating shaft 200, as shown in FIG. Figures 1 to 4 As shown, that is, when the lower connecting rod 300 moves left and right, the lower connecting rod 300 drives the lower row of sub-swing blades 110 to rotate left and right.

[0067] When the left-right displacements of the upper connecting rod 300 and the lower connecting rod 300 are the same, the upper sub-swing blade 110 and the lower sub-swing blade 110 rotate at the same angle, and the upper sub-swing blade 110 and the lower sub-swing blade 110 are staggered and spliced together through the connecting portion 113 to form a complete swing blade 100. At the same time, if the left-right movement speeds of the upper connecting rod 300 and the lower connecting rod 300 are also the same, that is, when the upper connecting rod 300 and the lower connecting rod 300 move synchronously, the upper sub-swing blade 110 and the lower sub-swing blade 110 are spliced together to form a complete swing blade 100. At this time, the upper connecting rod 300 and the lower connecting rod 300 move synchronously left and right, and the swing blade 100 swings left and right. At this time, the state of the swing blade 100 is called the wind-guiding state.

[0068] When the left-right displacements of the upper and lower connecting rods 300 differ, the upper and lower sub-blades 110 rotate at different angles, and the blade 100 is divided into two parts: the upper sub-blade 110 and the lower sub-blade 110. Furthermore, if the upper and lower connecting rods 300 do not move synchronously, the upper and lower sub-blades 110, 110, each independently move left and right to guide the wind. This state of the blade 100 is called a wind-disturbing state.

[0069] Specifically, the specific method of using the air conditioner indoor unit 1 is as follows:

[0070] When the air conditioner is turned on, the sensing device 30 is turned on and enters the working state at the same time.

[0071] The sensing device 30 determines that there is no one in the area facing the air outlet 20 of the air conditioner indoor unit 1.

[0072] In order to quickly and evenly adjust the indoor temperature, the swing blade assembly 10 is adjusted to the air guide mode. At this time, the air guide volume of the swing blade assembly 10 is relatively large. Specifically:

[0073] The left and right displacements of the upper connecting rod 300 and the lower connecting rod 300 are controlled to be the same. At this time, the rotation angles of the upper sub-swing blade 110 and the lower sub-swing blade 110 are the same. The main plates 111 of the upper and lower sub-swing blades 110 are located in the same plane and are staggered and spliced with each other to form a complete swing blade 100.

[0074] The upper connecting rod 300 and the lower connecting rod 300 are controlled to move synchronously, and the complete sub-swing blade 110 moves left and right. This mode is called the wind guide mode, which makes the indoor temperature quickly uniform.

[0075] The sensing device 30 determines that there is a person on the left side of the area facing the air outlet 20 of the air conditioner indoor unit 1.

[0076] In order to prevent the air from the air outlet 20 from blowing directly at people and to quickly equalize the indoor temperature, the right swing blade assembly 10 is controlled to continue to maintain the wind guide mode, and the left swing blade assembly 10 is controlled to adjust to the wind scrambling mode. At this time, the air from the left side of the air outlet 20 is relatively soft, preventing the air from the air outlet 20 from blowing directly at people. Specifically:

[0077] The left upper and lower links 300 are controlled to move at different left and right displacements, resulting in the upper and lower sub-blades 110 rotating at different angles. The left side of the pendulum 100 is divided into two parts, the upper and lower sub-blades 110, 110. In this case, the pendulum assembly 10 is in the wind-spinning mode. Alternatively, the upper and lower links 300 are controlled to move asynchronously, with the upper and lower sub-blades 110, 110, each moving left and right to guide the wind. In this case, the pendulum 100 is in the wind-spinning mode.
