Swing blade assembly for air outlet of air conditioner and air conditioner

Abstract

The present invention provides a pendulum blade assembly for an air outlet of an air conditioner and an air conditioner. The pendulum blade assembly includes one or more pendulum blades, one or more of which are configured to be positioned at the air outlet of the air conditioner. Furthermore, each pendulum blade includes two sub-pendulum blades, each of which is hollowed out, and the hollowed-out shapes of the two sub-pendulum blades complement each other. The two sub-pendulum blades are configured to swing independently or synchronously. The hollowed-out portions of the two sub-pendulum blades are staggered and spliced to form a single pendulum blade. The two sub-pendulum blades swing synchronously, allowing the pendulum blade to swing or swing to a preset angle. The two sub-pendulum blades pass through each other through the hollowed-out portions, allowing them to swing independently or to a preset angle. While the pendulum blade can guide air independently, it can also be split into two sub-pendulum blades to guide air independently. When the pendulum blade guides air independently, the air flow is relatively large, which helps to quickly and evenly adjust the indoor temperature. When the sub-pendulum blades swing independently, air is blown out through the hollowed-out portions, resulting in a relatively soft air flow at that location.

[0007] The hollow parts of the two sub-oscillating leaves are staggered and spliced to form the two sub-oscillating leaves into an integral oscillating leaf, and the two sub-oscillating leaves swing synchronously to make the oscillating leaf swing or swing to a preset angle;

[0008] The two sub-swing blades pass through each other through the hollow portion and swing independently or to a preset angle.

[0009] Optionally, the hollow shapes of the two sub-oscillating leaves are both long strips arranged in sequence.

[0010] Optionally, each sub-swing leaf further includes:

[0015] Optionally, each sub-swing leaf further includes:

[0016] The connecting portion is provided on a side of the rotating sleeve opposite to the main body plate and extends in a direction away from the main body;

[0017] The swing blade assembly also includes:

[0018] The two connecting rods are perpendicular to the rotating shaft and are arranged in sequence along the axial direction of the rotating shaft; the two connecting rods are connected to the connecting parts of the two sub-swing leaves in a one-to-one correspondence, and are used to respectively drive the sub-swing leaves to rotate relative to the rotating shaft.

[0019] Optionally, the swing blade assembly further includes:

[0020] At least two motors are used to respectively drive at least two connecting rods to move back and forth in a direction perpendicular to the rotating shaft.

[0021] Optionally, the swing blade assembly further includes:

[0022] A positioning sleeve is sleeved on the rotating shaft;

[0023] Each rotating sleeve engages with a positioning sleeve.

[0024] Optionally, there are multiple swing blades, and the multiple swing blades are arranged in sequence along the length direction of the connecting rod;

[0025] The connecting parts of the two sub-pendulum blades of each pendulum blade are connected to the two connecting rods in a one-to-one correspondence.

[0026] Optionally, the air conditioner indoor unit is a wall-mounted air conditioner indoor unit having a long strip-shaped air outlet; the two connecting rods are respectively arranged along the length direction of the air outlet, and the motor drives the connecting rods to move back and forth along the length direction of the air outlet.

[0027] Optionally, multiple rotating shafts are fixed at the air outlet.

[0028] According to a second aspect of the present invention, the present invention further provides an air conditioner comprising any one of the above swing blade assemblies.

[0029] The present invention provides a pendulum blade assembly for an air outlet of an air conditioner and an air conditioner, wherein the pendulum blade assembly includes one or more pendulum blades, and the one or more pendulum blades are used to be arranged at the air outlet of the air conditioner. In addition, each pendulum blade includes two sub-pendulum blades, each of which is hollowed out, and the hollowed-out shapes of the two sub-pendulum blades complement each other, and the two sub-pendulum blades are configured to swing independently or synchronously.

The two sub-pendulum blades pass through each other through the hollowed-out portions and swing independently or swing to a preset angle. Because the pendulum blade has two modes, namely, air guiding and wind disturbing, the air supply form is diversified to meet different needs. That is, when the pendulum blade is in the air guiding mode, the air guiding area of the pendulum blade is relatively large, and the air guiding volume of the pendulum blade is relatively large, which is conducive to quickly and evenly adjusting the indoor temperature. When the swing blade mode is the wind disturbance mode, the two sub-swing blades pass through each other through the hollow part and swing individually or to a preset angle. When the sub-swing blades swing individually, the wind blows out through the hollow part, making the wind out at this location softer.

[0042] like Figures 1 to 7 As shown, this embodiment provides a pendulum blade assembly 10 for the air outlet 20 of an air conditioner. The pendulum blade assembly 10 includes one or more pendulum blades 100, and the one or more pendulum blades 100 are used to be set at the air outlet 20 of the air conditioner. In addition, 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. 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. The two sub-pendulum blades 110 pass through each other through the hollow portions 1111 and swing individually or swing to a preset angle.

[0043] The hollow portions 1111 of the two sub-swing blades 110 are staggered and spliced together to form an integral swing blade 100. The two sub-swing blades 110 swing synchronously to cause the swing blade 100 to swing or swing to a preset angle. In this case, the wind guide area of the swing blade 100 is relatively large, and the wind guide volume of the swing blade 100 is relatively large, which is conducive to quickly uniformizing the indoor temperature. The mode of the swing blade 100 is the wind guide mode. The two sub-swing blades 110 pass through each other through the hollow portions 1111 and swing independently or swing to a preset angle. When the sub-swing blades 110 swing independently, the wind blows out through the hollow portions 1111, making the wind outflow at that location relatively soft. In this case, the mode of the swing blade 100 is the wind swaying mode.

[0044] In this embodiment, there are two sub-pendulum blades 110, and the two sub-pendulum blades 110 are arranged from top to bottom and staggered at the contact point to form a sub-pendulum blade 110. For the convenience of description, the sub-pendulum blade 110 located on the upper side is referred to as the upper sub-pendulum blade 110, and the sub-pendulum blade 110 located on the lower side is referred to as the lower sub-pendulum blade 110. Obviously, the pendulum blade 100 including two sub-pendulum blades 110 is merely exemplary. For example, the number of sub-pendulum blades 110 can also be multiple, and multiple sub-pendulum blades 110 are arranged in sequence from top to bottom, and two adjacent sub-pendulum blades 110 are staggered and spliced so that multiple sub-pendulum blades 110 form a complete pendulum blade 100. Based on the above reasons, the shape and number of the sub-pendulum blades 110 are optional.

[0045] 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 2 to 7 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 2 to 7 As shown, the two sub-oscillating blades 110 have a hollowed-out shape that is a horizontal strip. Obviously, the hollowed-out shape of the hollow portion 1111 is merely exemplary; for example, the hollowed-out shape of the two sub-oscillating blades 110 can also be a vertical strip or other shape. The horizontal strip-shaped hollowed-out shape of the sub-oscillating blades 110 facilitates directing air to the left and right sides when the sub-oscillating blades 110 swing. While the sub-oscillating blades 110 soften the airflow, they also contribute to uniform indoor temperature.

[0046] The hollowed-out shapes of the two sub-oscillating blades 110 complement each other. That is, on the same horizontal plane, when the upper sub-oscillating blade 110 has a long strip-shaped notch at this location, the lower sub-oscillating blade 110 has a long strip-shaped plate at this location. The long strip can be inserted into the long strip-shaped notch, so that the two sub-oscillating blades 110 are staggered and spliced together to form a single oscillating blade 100.

[0047] 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.

[0048] In some other embodiments, the hollow shapes of the two sub-oscillating leaves 110 are both long strips arranged in sequence. Figures 2 to 7 As shown, the hollowed-out shapes of the sub-oscillating blades 110 are all horizontally elongated strips. Obviously, this is not the only option. For example, the hollowed-out shapes of the sub-oscillating blades 110 can be vertically elongated strips. The horizontally elongated hollowed-out shapes of the sub-oscillating blades 110 facilitate directing the airflow to the left and right sides when the sub-oscillating blades 110 swing. The sub-oscillating blades 110 not only soften the airflow but also contribute to uniform indoor temperature.

[0049] In some other embodiments, each sub-swing blade 110 further includes a main body plate 111 and a rotating shaft sleeve 112. The main body plate 111 has a hollow portion 1111. The rotating shaft sleeve 112 is formed at the edge of the main body plate 111 and extends outward. The swing blade assembly 10 further includes one or more rotating shafts 200. The one or more rotating shafts 200 are provided in a one-to-one correspondence with the swing blade 100, and the rotating shaft sleeve 112 of the sub-swing blade 110 of each swing blade 100 is sequentially sleeved on the rotating shaft 200.

[0050] 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.

[0051] 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.

[0052] The rotating shaft sleeves 112 of the sub-swing blades 110 of each pendulum blade 100 are sequentially sleeved on the rotating shaft 200. The sub-swing blades 110 are arranged from top to bottom on the rotating shaft 200. For convenience of distinction, the sub-swing blades 110 of each pendulum blade 100 are respectively referred to as upper sub-swing blades 110 and lower sub-swing blades 110 from top to bottom. The upper sub-swing blades 110 of the multiple pendulum blades 100 are on the same horizontal line, that is, the upper sub-swing blades 110 of the multiple pendulum blades 100 are located in a row. The lower sub-swing blades 110 of the multiple pendulum blades 100 are on the same horizontal line, that is, the lower sub-swing blades 110 of the multiple pendulum blades 100 are located in a row.

[0053] 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.

[0054] In some other embodiments, each sub-oscillating blade assembly 10 further includes a positioning sleeve 500, which is sleeved on the rotating shaft 200; each rotating sleeve 112 engages with a positioning sleeve 500. When the driving device drives the rotating sleeve 112 to rotate, the rotating device drives the sub-oscillating blade 110 to rotate, and the rotating sleeve 112 of the sub-oscillating blade 110 drives the positioning sleeve 500 to rotate. When the sub-oscillating blade 110 or the oscillating blade 100 rotates to a preset angle to guide air, the air from the air outlet 20 blows toward the sub-oscillating blade 110, generating a certain impact force on the sub-oscillating blade 110. This impact force may drive the oscillating blade 100 to rotate, and this impact force in turn drives the rotating sleeve 112 to rotate. When the impact force from the air outlet 20 drives the oscillating blade 100 to rotate, the oscillating blade 100 deviates from the preset angle, and the oscillating blade 100 no longer guides air at the preset angle. In other words, the impact force of the air outlet will affect the preset air guidance angle. The positioning sleeve 500 is engaged with the rotating sleeve 112 , and the positioning sleeve 500 is used to prevent the impact force of the outgoing wind from causing the swing blade 100 to deviate from a preset angle.

[0055] In some other embodiments, each sub-oscillating blade 110 further includes a connecting portion 113, which is disposed on the side of the rotating sleeve 112 opposite the main plate 111 and extends away from the main body. The oscillating blade assembly 10 further includes two connecting rods 300, which are perpendicular to the rotating shaft 200 and arranged in sequence along the axial direction of the rotating shaft 200. The two connecting rods 300 are connected to the connecting portions 113 of the two sub-oscillating blades 110 in a one-to-one correspondence, respectively driving the sub-oscillating blades 110 to rotate relative to the rotating shaft 200.

[0056] The connecting portion 113 is disposed on the side of the rotating sleeve 112 opposite to the main plate 111, that is, Figures 2 to 7 As shown, the connecting portion 113 and the main plate 111 are both connected to the rotating shaft sleeve 112, and the connecting portion 113 and the main plate 111 are in opposite directions. As a specific embodiment, Figure 7 As shown, the main plate 111 and the connecting portion 113 are both connected to the side wall of the rotating sleeve, and the main plate 111 and the connecting portion 113 are opposite to each other. Figure 7 As shown, 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, the rotating sleeve 112, and the connecting portion 113 are arranged in sequence 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.

[0057] 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.

[0058] The two connecting rods 300 are perpendicular to the rotating shaft 200. As a specific embodiment, Figures 6 and 7 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 6 and 7 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.

[0059] 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 6 and 7 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 6 and 7 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 blades 110 to rotate left and right. When the lower connecting rod 300 moves in a direction perpendicular to the rotating shaft 200, as shown Figures 6 and 7 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.

[0060] 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.

[0061] 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.

[0062] It can be seen that the structure of the swing blade assembly 10 is simple and easy to control.

[0063] In some other embodiments, there are multiple pendulum blades 100, and the multiple pendulum blades 100 are sequentially arranged along the length direction of the connecting rod 300. The connecting portions 113 of the two sub-pendulum blades 110 of each pendulum blade 100 are connected to the two connecting rods 300 in a one-to-one correspondence.

[0064] like Figures 6 and 7As shown, the connecting rod 300 is arranged horizontally, and the multiple pendulum blades 100 are also arranged horizontally, and the multiple pendulum blades 100 are arranged in a row. The rotating shaft 200 of each pendulum blade 100 is arranged vertically, and 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 convenience, 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 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 in a row. The connecting parts 113 of the two sub-swing blades 110 of each swing blade 100 are connected to the two connecting rods 300 in a one-to-one correspondence, that is, the upper connecting rod 300 is connected to the upper sub-swing blade 110 , and the lower connecting rod 300 is connected to the lower sub-swing blade 110 .

[0065] This structure of the swing blade assembly 10 is simple and is conducive to the control of the upper row of sub-swing blades 110, the lower row of sub-swing blades 110 and the swing blades 100.

[0066] In some other embodiments, the swing blade assembly 10 further includes a drive device, which includes at least two motors, each of which is configured to drive at least two connecting rods 300 to move back and forth in a direction perpendicular to the rotating shaft 200. The motors each drive a different connecting rod 300, thereby facilitating separate control of the different connecting rods 300.

[0067] In some other embodiments, the air conditioner indoor unit 1 is a wall-mounted air conditioner indoor unit 1, and multiple rotating shafts 200 are fixed to the air outlet 20. The wall-mounted air conditioner indoor unit 1 has an elongated air outlet 20. Two connecting rods 300 are respectively arranged along the length of the air outlet 20, and the motor drives the connecting rods 300 to move back and forth along the length of the air outlet 20.

[0068] In some other embodiments, the air conditioner indoor unit 1 includes a sensing device 30 and at least two groups 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; at least two groups 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 located in that area switches to a wind disturbance mode.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] In some other embodiments, such as Figures 8 and 9 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.

[0073] The size and number of regions can be selected as needed. In this embodiment, Figures 8 and 9 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.

[0074] 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.

[0075] Specifically, if Figures 8 and 9 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 8 and 9As 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.

[0076] 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.

[0077] 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 .

[0078] Specifically, the specific method of using the air conditioner indoor unit 1 is as follows:

[0079] When the air conditioner is turned on, the sensing device 30 is turned on and enters the working state at the same time.

[0080] 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.

[0081] 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:

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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:

[0086] 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.
