Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of the present application.

[0040] In addition, if the embodiments of the present application involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist, and is also not within the scope of protection claimed by the present application.

[0041] The present application provides an air conditioner indoor unit, which can be selected as a floor type air conditioner indoor unit or a vertical hanging type air conditioner indoor unit, etc. The present application takes the floor type air conditioner indoor unit as an example for description, but the present application is not limited thereto.

[0042] In the embodiments of the present application, as shown in the drawings, Figures 1 to 11 The air conditioner indoor unit comprises a shell 10, the shell 10 is provided with an air duct 11 and an air outlet 12 communicating with the air duct 11; a wind diffuser 20 comprising a wind diffuser plate 21 and a cyclone module 22; wherein the wind diffuser plate 21 is rotatably installed at the air outlet 12, the cyclone module 22 is rotatably installed at the air outlet 12, and the wind diffuser plate 21 and the cyclone module 22 can rotate relative to each other.

[0043] In the embodiment, the shell 10 extends in the up-down direction as a whole, and the horizontal cross-sectional shape of the shell 10 can be circular, oval, rectangular, etc., which can be selected according to actual use requirements and is not specifically limited here. The shape of the air outlet 12 can be a long rectangular shape or a long oval shape, etc., and the long air outlet 12 can increase the air supply amount and the air supply range. The shell 10 is provided with an air inlet, which can be arranged at the back of the shell 10. The shell 10 is also provided with a heat exchanger, a fan, etc. The external air enters the shell 10 through the air inlet, is subjected to the heat exchange of the heat exchanger, and then is blown out through the air outlet 12 under the action of the fan. The position of the air outlet 12 is not limited, for example, the air outlet 12 is arranged on the front panel of the shell 10, and only needs to satisfy the communication between the air outlet 12 and the air duct 11 so that the air in the air duct 11 can be blown out from the air outlet 12. The air diffuser plate 21 and the cyclone module 22 can rotate relative to the shell 10. It needs to be noted that the rotation processes of the air diffuser plate 21 and the cyclone module 22 are independent of each other, and the rotation tracks of the air diffuser plate 21 and the cyclone module 22 do not interfere with each other, for example, the rotation track of the air diffuser plate 21 is located on the inner circumferential side of the cyclone module 22.

[0044] The air diffuser plate 21 has a first air diffusing position covering the air outlet 12 and a first air avoiding position avoiding the air flow on its rotation track, and the cyclone module 22 has a second air diffusing position covering the air outlet 12 and a second air avoiding position avoiding the air flow on its rotation track. The air diffuser plate 21 and the cyclone module 22 can both play a role in dispersing and slowing down the air flow, thereby reducing the flow rate of the air flow flowing out of the air outlet 12. Of course, the flow rate of the air flow after flowing through the air diffuser plate 21 will be smaller than that after flowing through the cyclone module 22, thereby enabling the air conditioner indoor unit to realize normal air outlet mode, soft wind feeling mode and windless mode.

[0045] As shown in Figure 1 and Figure 2 , in the normal air outlet mode, the air diffuser plate 21 is rotated to the first air avoiding position, and the cyclone module 22 is rotated to the second air avoiding position, that is, the air outlet 12 is not covered, so that the air flow can be directly blown out from the air outlet 12.

[0046] As shown in Figure 3 and Figure 4 , in the windless air outlet mode, the air diffuser plate 21 is rotated to the first air diffusing position, and the cyclone module 22 is rotated to the second air avoiding position. The air flow is dispersed to form a scattered flow after passing through the air diffuser plate 21, and then flows out of the air outlet 12. The air diffuser plate 21 is provided with a plurality of air diffusing holes 211, the diameter of the air diffusing hole 211 is not less than 2 mm and not more than 5 mm, thereby effectively reducing the flow rate of the air flow under the condition of ensuring the air supply amount, to a greater extent, to meet the user's demand.

[0047] As shown in Figure 5 and Figure 6As shown, in the gentle breeze air outlet mode, the air diffuser 21 rotates to the first windproof position, and the vortex module 22 rotates to the second air diffuser position. The airflow is dispersed by the vortex module 22 to form a vortex before flowing out of the air outlet 12.

[0048] Specifically, such as Figures 7 to 9 As shown, the rotation trajectory of the diffuser plate 21 is located on the outer periphery of the rotation trajectory of the vortex module 22. In this embodiment, the rotation trajectory of the diffuser plate 21 and the rotation trajectory of the vortex module 22 can be coaxially arranged to reduce the space occupied by the movement of the diffuser plate 21 and the vortex module 22, so as to make the structure of the diffuser frame 20 more compact and reduce the occupation of the internal space of the housing 10. The diffuser plate 21 and the vortex module 22 can be arranged in an arc shape extending along their respective rotation trajectories to further reduce the space occupied by rotation, while ensuring that their rotation trajectories avoid each other. In practical applications, such as Figure 9 As shown, the curvature of the diffuser plate 21 is greater than that of the vortex module 22, so that the vortex module 22 as a whole can maintain a sufficient distance from the diffuser plate 21, effectively avoiding mutual interference between the two during rotation.

[0049] like Figures 7 to 9 As shown, the indoor unit of the air conditioner also includes a louver assembly installed on the swirl module 22, the louver assembly being located on the inner periphery of the swirl module 22. In this embodiment, the louver assembly rotates together with the swirl module 22. Since the louver assembly is located on the inner periphery of the rotation trajectory of the swirl module 22, while the rotation trajectory of the diffuser plate 21 is located on the outer periphery of the rotation trajectory of the swirl module 22, the louver assembly and the swirl module 22 will not interfere with each other. The louver assembly can be oscillatingly installed on the swirl module 22. In normal air outlet mode, the louver assembly can change the direction of the airflow from the outlet 12 by oscillating, specifically by oscillating up and down or left and right, to meet the air supply requirements in different directions. Placing the louver assembly on the inner periphery of the rotation trajectory of the swirl module 22 not only allows for adjustment of the air outlet direction but also effectively utilizes the internal space of the diffuser plate 20, improving space utilization and making the internal structure of the indoor unit of the air conditioner simpler and more compact.

[0050] like Figure 7 As shown, the swirl module 22 includes a mounting plate 221 and swirl fan blades 223. The mounting plate 221 has a mounting opening 222, and the swirl fan blades 223 are disposed in the mounting opening 222 and connected to the peripheral wall of the mounting opening 222. In this embodiment, the mounting opening 222 can be circular, and the swirl fan blades 223 are fixed at the mounting opening 222. When the airflow passes through the swirl fan blades 223, it is dispersed by the swirl fan blades 223, achieving the effect of deceleration and flow amplification. Of course, the swirl fan blades 223 can also be rotatably disposed in the mounting opening 222 to improve the deceleration and flow amplification effect on the airflow.

[0051] likeFigure 7 As shown, the cyclone fan blade 223 comprises a support portion 224 arranged in the middle of the mounting port 222, and a wind guide strip 225 connecting the support portion 224 and the peripheral wall of the mounting port 222, and the louver assembly comprises a louver 31 rotatably connected to the support portion 224. In this embodiment, the number of wind guide strips 225 is multiple and arranged in the circumferential direction of the support portion 224, the support portion 224 is provided with an axle hole, and the louver 31 is provided with an axle, which is rotatably connected to the axle hole, so as to realize the rotatable connection between the louver 31 and the cyclone module 22. The wind guide surface of the louver 31 is always perpendicular to the air outlet section of the mounting port 222, so that the louver 31 will not hinder the airflow passing through the cyclone fan blade 223, so as to ensure the normal operation of the soft wind feeling mode. Connecting the louver 31 to the support portion 224 of the cyclone fan blade 223 can effectively utilize the existing structure of the cyclone module 22, so that the overall structure of the air diffuser 20 is more simple and compact.

[0052] In the normal air outlet mode, the louver 31 will be exposed to the air outlet 12, at this time, the air outlet airflow is not blocked by the air diffuser plate 21 or the cyclone module 22, and the wind deflection effect of the louver 31 is more obvious, so the wind guide surface of the louver 31 will be inclined towards the air outlet 12 in the swinging process of the louver 31. The rotatable connection between the louver 31 and the support portion 224 is the up-down swinging process of the louver 31 relative to the air outlet 12, so that in the normal air outlet mode, the up-down wind deflection can be realized by the rotation of the louver 31.

[0053] As shown in Figure 10 and Figure 11 As shown, the number of mounting ports 222 is at least two, each of the mounting ports 222 is provided with the cyclone fan blade 223, each of the support portions 224 of the cyclone fan blades 223 is connected with the louver 31, and the at least two louvers 31 are linked by the connecting rod 32. In this embodiment, the mounting plate 221 extends along the length direction of the air outlet 12, the multiple mounting ports 222 are arranged in the length direction of the mounting plate 221, and the number and position of the cyclone fan blades 223 and the louvers 31 correspond to the mounting ports 222, so as to improve the wind deflection effect. The multiple louvers 31 are linked by the connecting rod 32, so that only one louver 31 or the connecting rod 32 needs to be driven to drive all the louvers 31 to swing. In actual application, the air diffuser 20 further comprises a first driving device 60 for driving the connecting rod 32 to extend or retract, so as to automatically swing the louver 31.

[0054] The end of the cyclone module 22 is provided with a first matching part, and the end of the air diffuser 21 is provided with a second matching part, and the first matching part and the second matching part are rotatable matched. In the embodiment, the first matching part can be provided only at one end of the cyclone module 22, or can be provided at both ends of the cyclone module 22, which is not limited here, and the number of the second matching part corresponds to the first matching part. The specific form of the first matching part and the second matching part is not limited, as long as they can be rotatable matched. The first matching part and the second matching part can rotate coaxially after matched, thereby driving the cyclone module 22 and the air diffuser 21 to rotate. Through the matched connection of the first matching part and the second matching part, the rotation process of the cyclone module 22 and the air diffuser 21 can be more stable, and mutual interference caused by the deviation of the activity track of one of them can be avoided.

[0055] As shown in Figure 10 and Figure 11 , the first matching part includes a first support plate 41 connected to one end of the cyclone module 22, and the second matching part includes a first matching plate 51 connected to one end of the air diffuser 21, and the first support plate 41 and the first matching plate 51 are rotatably connected. In the embodiment, the first support plate 41 is connected to the top end of the cyclone module 22, the first matching plate 51 is connected to the top end of the air diffuser 21, and the first support plate 41 and the first matching plate 51 are superimposed. Since the rotation track of the cyclone module 22 is located on the inner circumferential side of the rotation track of the air diffuser 21, the first support plate 41 is superimposed below the first matching plate 51, and the upper surface of the first support plate 41 is provided with a rotating shaft, and the lower surface of the first matching plate 51 is provided with a shaft groove, and the rotating shaft and the bearing are matched to realize the rotation matching of the first support plate 41 and the first matching plate 51.

[0056] As shown in Figure 8 , the air conditioner indoor unit further comprises a first driving device 60 mounted on the shell 10, for driving the first matching plate 51 to move. In the embodiment, the upper surface of the first matching plate 51 is provided with a transmission shaft, and the output shaft of the first driving device 60 is connected with the transmission shaft, which can drive the first matching plate 51 to rotate, thereby driving the air diffuser 21 to automatically rotate.

[0057] As shown in Figure 10 and Figure 11As shown, the first matching part further comprises a second support plate 42 connected to the other end of the cyclone module 22, the second matching part further comprises a second matching plate 52 connected to the other end of the air diffuser 21, and the second support plate 42 is rotatably connected to the second matching plate 52. In the embodiment, the second support plate 42 is connected to the bottom end of the cyclone module 22, the second matching plate 52 is connected to the bottom end of the air diffuser 21, the second support plate 42 is stacked on the second matching plate 52, and the lower surface of the second support plate 42 is provided with a rotating shaft, the second matching plate 52 is provided with a through hole, and the rotating shaft is rotatably matched with the through hole, so as to realize the rotation matching of the first support plate 41 and the first matching plate 51.

[0058] As shown in the drawings, Figure 8 As shown, the air conditioner further comprises a second driving device 70 installed on the shell 10, used to drive the second support plate 42 to move. In the embodiment, the rotating shaft of the second support plate 42 protrudes from the lower surface of the second matching plate 52 through the through hole, the second driving device 70 is installed below the air diffuser 20, and the output shaft of the second driving device 70 is connected with the rotating shaft of the second support plate 42, so as to drive the second support plate 42 to rotate, thereby driving the cyclone module 22 to automatically rotate.
