[0049] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0050] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0051] The following will describe in detail the air conditioner indoor unit 100 according to an embodiment of the present invention in conjunction with Figures 1 - 20 the accompanying drawings.

[0052] Referring to Figures 1 - 3 the drawings, the air conditioner indoor unit 100 according to an embodiment of the present invention includes a first housing 11, a second housing 12, an air duct component 2, a fan 3, and a first driving device 4.

[0053] As Figure 1 shown in the drawings, the second housing 12 is installed on the first housing 11, and the first housing 11 and the second housing 12 are connected to form the housing of the air conditioner indoor unit 100. The housing of the air conditioner indoor unit 100 can prevent external impurities and water droplets from entering the interior of the air conditioner indoor unit 100 and protect the internal space of the air conditioner indoor unit 100. Among them, referring to Figure 9 the drawings, the second housing 12 has a housing air duct 123, and the housing air duct 123 can pass air flow and guide the air flow direction to achieve directional air supply of the air conditioner indoor unit 100.

[0054] The air duct component 2 can at least partially enter the second housing 12. For example, in the embodiments shown in Figure 2 , Figure 6 and Figures 10 - 13 the drawings, the air duct component 2 is at least partially disposed in the second housing 12. The air duct component 2 has a air supply channel 20, and the housing air duct 123 is communicated with the air supply channel 20. For example, the air duct component 2 can be entirely accommodated inside the second housing 12; or for another example, a part of the air duct component 2 can be accommodated inside the second housing 12. The air duct component 2 is accommodated in the second housing 12, making the structure of the air conditioner indoor unit 100 more compact and occupying less space; in other embodiments, the air duct component 2 is disposed outside the second housing 12, and the air duct component 2 can at least partially enter the second housing 12. Since the air supply channel 20 in the air duct component 2 is communicated with the housing air duct 123 of the second housing 12, the air flow in the air supply channel 20 can be guided to the housing air duct 123 and then sent through the housing air duct 123. That is to say, the housing air duct 123 and the air supply channel 20 together form the air flow channel of the air conditioner indoor unit 100.

[0055] As Figure 2 and Figures 10 - 13As shown, the blower 3 can send air into the air supply channel 20, that is, the blower 3 drives the air to form an air current, and the air current can be driven to the air supply channel 20 and the housing air duct 123. That is to say, the blower 3 is communicated with the housing air duct 123 through the air supply channel 20.

[0056] It should be noted that the blower 3 can be located upstream of the air supply channel 20; the blower 3 can also be located in the middle of the air supply channel 20; the blower 3 can also be located downstream of the air supply channel 20. The specific position of the blower 3 is not limited here. For the convenience of description below, the blower 3 is located upstream of the air supply channel 20, and the housing air duct 123 is communicated with the downstream of the air supply channel 20. The blower 3 can be a cross-flow blower, and the blower 3 can also be a centrifugal blower; the blower 3 can include one cross-flow blower; the blower 3 can include one centrifugal blower; the blower 3 can also include one cross-flow blower and one centrifugal blower. The type and quantity of the blower 3 are not limited here.

[0057] As Figure 1 and Figure 3 shown, the first driving device 4 can drive the second housing 12 to rotate. The second housing 12 has a rotation axis, and the second housing 12 can rotate around the rotation axis under the drive of the first driving device 4 so that the housing air outlet 125 of the housing air duct 123 blows air in different directions. For example, the housing air outlet 125 of the housing air duct 123 can face the front side of the air conditioner indoor unit 100, so that the air conditioner indoor unit 100 blows air forward, as Figure 11 shown; again, for example, the housing air outlet 125 of the housing air duct 123 can face both sides of the air conditioner indoor unit 100, so that the air conditioner indoor unit 100 blows air to both sides, as Figures 12 - 13 shown.

[0058] It should be noted that when the housing air outlet 125 blows air to both sides of the air conditioner indoor unit 100, the housing air outlet 125 can include one. When the second housing 12 rotates to the left side of the air conditioner indoor unit 100, the housing air outlet 125 blows air to the left side of the air conditioner indoor unit 100. When the second housing 12 rotates to the right side of the air conditioner indoor unit 100, the housing air outlet 125 blows air to the right side of the air conditioner indoor unit 100; when the housing air outlet 125 blows air to both sides of the air conditioner indoor unit 100, the second housing 12 can be two. One second housing 12 includes one housing air outlet 125, and each housing air outlet 125 blows air to one side of the air conditioner indoor unit 100 and the air conditioner indoor unit 100 can blow air to both sides at the same time.

[0059] In the related art closest to the present application, some cabinet air conditioners achieve front-side air supply by setting an air outlet at the top of the cabinet air conditioner; some cabinet air conditioners adopt a solution of arranging a rotary drum air guide component inside the cabinet air conditioner to increase the air supply range of the cabinet air conditioner. However, the air outlets of the above two types of cabinet air conditioners are fixed on the housing, which will limit the air supply angle and air supply range of the cabinet air conditioner. In the present application, the second housing 12 undertakes the functions of protecting the housing of the indoor unit 100 of the air conditioner and guiding the air flow direction. The indoor unit 100 of the air conditioner includes a second housing 12, a housing air duct 123 that can change its position, and a housing air outlet 125 that changes its position. The indoor unit 100 of the air conditioner can increase the air supply range of the indoor unit 100 of the air conditioner without setting an air outlet at the top. The air supply area can not only cover the air supply area of the air conditioner in the related art, but also cover the non-air supply area of the air conditioner in the related art. The maximum air supply range of the indoor unit 100 of the air conditioner in the present application can be a semi-circular area of 0° to 180°.

[0060] According to the indoor unit 100 of the air conditioner according to an embodiment of the present invention, the fan 3 can drive air to form an air flow and drive the air flow to flow through the communication air duct and the housing air duct 123 in sequence. The second housing 12 rotates around the rotation axis under the drive of the first drive device 4 so that the housing air outlet 125 of the housing air duct 123 blows air in different directions. By the rotation of the second housing 12, the positions of the housing air duct 123 and the housing air outlet 125 are changed; the housing air outlet 125 of the housing air duct 123 can face the front side of the indoor unit 100 of the air conditioner, so that the indoor unit 100 of the air conditioner supplies air forward; the housing air outlet 125 of the housing air duct 123 can face both sides of the indoor unit 100 of the air conditioner, so that the indoor unit 100 of the air conditioner supplies air to both sides, which increases the air supply range of the indoor unit 100 of the air conditioner.

[0061] As Figures 4 - 6 shown, according to some embodiments of the present invention, the air duct component 2 includes an air duct first side wall 21 and an air duct second side wall 22. The air duct first side wall 21 and the air duct second side wall 22 are separated and oppositely arranged. An air duct air inlet 23 is formed between one end of the air duct first side wall 21 and one end of the air duct second side wall 22, and an air duct air outlet 24 is formed between the other end of the air duct first side wall 21 and the other end of the air duct second side wall 22. An air supply channel 20 is formed between the air duct first side wall 21 and the air duct second side wall 22, and the air supply channel 20 is communicated with the air duct air inlet 23, and the air supply channel 20 is communicated with the air duct air outlet 24. Specifically, the fan 3 drives the air flow to pass through the air duct air inlet 23, and the air flow flows along the air duct first side wall 21 and the air duct second side wall 22, and the air flow flows out from the air duct air outlet 24. Thus, the air duct component 2 can effectively guide the air flow, reduce turbulence and air volume loss.

[0062] As Figures 4 - 6As shown, by way of example, the air duct components 2 of the air conditioner indoor unit 100 include at least two, and a connecting plate 25 is provided between each adjacent pair of air duct components 2 to fix the relative positions of the plurality of air duct components 2.

[0063] As Figures 4 - 6 shown, optionally, the air duct components 2 include two, which are respectively a first air duct component 2a and a second air duct component 2b. The first air duct component 2a and the second air duct component 2b are symmetrically arranged, and are connected by a connecting plate 25 between the second side wall 22 of the air duct of the first air duct component 2a and the first side wall 21 of the air duct of the second air duct component 2b.

[0064] As Figure 6 shown, according to some embodiments of the present invention, the first side wall 21 of the air duct includes a first arc segment 213, and the second side wall 22 of the air duct includes a second arc segment 223. The first arc segment 213 and the second arc segment 223 are two arc plates on a first cylindrical surface, and the air duct air outlet 24 is formed between the first arc segment 213 and the second arc segment 223. By providing the first arc segment 213 and the second arc segment 223, the air flow can pass through the air supply channel 20 more smoothly, reducing the turbulence and noise generated when the air flow changes direction.

[0065] As Figure 6 shown, by way of example, in the air flow direction from the air duct air inlet 23 to the air duct air outlet 24, the diameter of the air duct air outlet 24 between the first arc segment 213 and the second arc segment 223 gradually increases.

[0066] As Figure 6 shown, in some specific examples, in the air flow direction from the air duct air inlet 23 to the air duct air outlet 24, the first side wall 21 of the air duct includes a first bending segment 211, a first straight segment 212 and a first arc segment 213 connected in sequence. The projection of the fan 3 on the first side wall 21 of the air duct is located at the first bending segment 211, and the air flow passing through the air duct air inlet 23 can blow to the first bending segment 211. The first bending segment 211 has a smooth transition, which is beneficial for the air flow to change the flow direction more smoothly and flow along the first side wall 21 of the air duct; a part of the air flow flows along the first bending segment 211 to the first straight segment 212, and then to the first arc segment 213.

[0067] As Figure 6As shown, in some specific examples, along the air flow direction from the air inlet 23 to the air outlet 24 of the air duct, the second side wall 22 of the air duct includes a second bent section 221, a second straight section 222, and a second arc section 223 that are connected in sequence. The distance that the air flow travels along the first bent section 211 is greater than the distance that the air flow travels along the second bent section 221. The second bent section 221 connects to the first end of the second straight section 222, and the second arc section 223 connects to the second end of the second straight section 222. The second end of the second straight section 222 is inclined in a direction away from the first side wall 21 of the air duct. That is to say, the shortest distance between the second end of the second straight section 222 and the first side wall 21 of the air duct is greater than the shortest distance between the first end of the second straight section 222 and the first side wall 21 of the air duct. Thus, the air supply channel 20 between the second straight section 222 and the first side wall 21 of the air duct is a gradually expanding section, which can increase the wind speed and wind force on the basis of reducing turbulence.

[0068] As Figures 7 - 10As shown, according to some embodiments of the present invention, the second housing 12 includes a first housing side wall 121 and a second housing side wall 122, and the first housing side wall 121 and the second housing side wall 122 are oppositely arranged and separated. The first housing side wall 121 includes a first outer side wall 1211 and a first inner side wall 1212. One end of the first outer side wall 1211 is connected to one end of the first inner side wall 1212, and a first space 1213 is formed between the first outer side wall 1211 and the first inner side wall 1212; the second housing side wall 122 includes a second outer side wall 1221 and a second inner side wall 1222. One end of the second outer side wall 1221 is connected to one end of the second inner side wall 1222, and a second space 1223 is formed between the second outer side wall 1221 and the second inner side wall 1222. When the second housing 12 rotates, the first arc segment 213 can enter the first space 1213, and the first arc segment 213 can also exit the first space 1213; the second arc segment 223 can enter the second space 1223, and the second arc segment 223 can also exit the second space 1223; the housing air duct 123 is formed between the first inner side wall 1212 and the second inner side wall 1222. The other end of the first outer side wall 1211 and the other end of the first inner side wall 1212 have a first notch 1214, and the first notch 1214 communicates with the first space 1213. The first arc segment 213 can enter and exit the first space 1213 through the first notch 1214; the other end of the second outer side wall 1221 and the other end of the second inner side wall 1222 have a second notch 1224, and the second notch 1224 communicates with the second space 1223. The second arc segment 223 can enter and exit the second space 1223 through the second notch 1224. The housing air duct 123 can rotate relative to the air duct component 2, so as to change the direction of the housing air outlet 125; for the first space 1213 in the second housing 12, when the second housing 12 rotates, the first arc segment 213 enters the first space 1213, and the first space 1213 has a maximum accommodation limit, which can play a role in limiting, so as to limit the extreme rotation position of the second housing 12 in the first direction; the effect of the second space 1223 in the second housing 12 is the same, which can limit the extreme rotation position of the second housing 12 in the second direction, and the first direction is opposite to the second direction.

[0069] In the related art, the air outlet of the air conditioner indoor unit is fixed. According to the layout requirements of the internal parts of different models of air conditioner indoor units, the positional relationship between the air duct outlet and the air conditioner air outlet can vary within a certain range. In some specific solutions, the sizes of the air duct outlet and the air conditioner air outlet are exactly the same, and the inner wall surfaces of the air duct outlet and the air conditioner air outlet are smoothly connected. In other specific solutions, the air duct outlet is relatively smaller than the air conditioner air outlet, and the projection of the air duct outlet on the plane where the air conditioner air outlet is located falls within the air conditioner air outlet. That is to say, in the related art, after the air flows out from the air duct outlet, it can directly flow through the air conditioner air outlet and then flow out. In the present application, between the air duct outlet 24 and the air outlet of the air conditioner indoor unit 100, there is a need to pass through the housing air duct 123, and the housing air duct 123 has a housing air outlet 125, and the housing air outlet 125 is the air outlet of the air conditioner indoor unit 100. When the second housing 12 rotates, the housing air outlet 125 rotates, that is, the air outlet of the air conditioner indoor unit 100 rotates to obtain a larger air-sweeping range.

[0070] As Figures 11 - 13 shown, by way of example, the air conditioner indoor unit 100 has at least three air outlet states, namely the first air outlet state S1, the second air outlet state S2, and the third air outlet state S3.

[0071] As Figure 11 shown, when the air conditioner indoor unit 100 is in the first air outlet state S1, the air conditioner indoor unit 100 can blow air forward, the housing air outlet 125 faces the front side of the air conditioner indoor unit 100, at least a part of the first arc segment 213 of the first side wall 21 of the air duct enters the first space 1213 and the first space 1213 cannot continue to accommodate any extra first side wall 21 of the air duct, and both the first arc segment 213 and the second arc segment 223 are in the first extreme position. For example, the first arc segment 213 can be entirely accommodated in the first space 1213; or for another example, the first arc segment 213 can be partially accommodated in the first space 1213.

[0072] As Figure 12 shown, when the air conditioner indoor unit 100 is in the second air outlet state S2, the air conditioner indoor unit 100 can blow air to both sides, the housing air outlet 125 faces both sides of the air conditioner indoor unit 100, at least a part of the second arc segment 223 of the second side wall 22 of the air duct enters the second space 1223 and the second space 1223 cannot continue to accommodate any extra second side wall 22 of the air duct, and both the first arc segment 213 and the second arc segment 223 are in the second extreme position. For example, the second arc segment 223 can be entirely accommodated in the second space 1223; or for another example, the second arc segment 223 can be partially accommodated in the second space 1223.

[0073] As Figure 13As shown, when the air conditioner indoor unit 100 is in the third air outlet state S3, the air outlet direction of the air conditioner indoor unit 100 is between the side air outlet and the forward air outlet. The first space 1213 can continue to accommodate the first arc segment 213, and the second space 1223 can continue to accommodate the second arc segment 223. The first arc segment 213 is located between the first extreme position and the second extreme position, and the second arc segment 223 is located between the second extreme position and the first extreme position.

[0074] As Figure 9 and Figure 10 As shown, according to some embodiments of the present invention, the first outer wall 1211 and the second outer wall 1221 are two arc plates on the second cylindrical surface. The diameter of the second cylindrical surface is greater than the diameter of the first cylindrical surface, and the second cylindrical surface is concentrically arranged with the first cylindrical surface. The first cylindrical surface can rotate relative to the second cylindrical surface. Since the second cylindrical surface and the first cylindrical surface are concentric cylinders, the first cylindrical surface can rotate more smoothly in the second cylindrical surface, reducing the occurrence of interference.

[0075] As Figure 9 As shown, according to some embodiments of the present invention, the second inner wall 1222 is configured as a straight plate, and the first inner wall 1212 includes a first straight plate segment 12121 and a second straight plate segment 12122. The first straight plate segment 12121 connects the first outer wall 1211 and the second straight plate segment 12122, and the second straight plate segment 12122 is inclined towards the first outer wall 1211 relative to the first straight plate segment 12121. Specifically, the second straight plate segment 12122 is located upstream of the housing air outlet 125. When the second straight plate segment 12122 is inclined towards the first outer wall 1211 relative to the first straight plate segment 12121, the air flow area upstream of the housing air outlet 125 is increased, so that more air flow can pass through, reducing the air volume loss. At the same time, the structure between the first inner wall 1212 and the second inner wall 1222 is a tapered structure, and the air flow area gradually decreases. Therefore, the speed and wind force of the air flow gradually increase, and the air flow can be blown farther.

[0076] As Figure 6 、 Figures 9 - 11As shown, in some specific examples, when the air conditioner indoor unit 100 is in the first air outlet state S1, the first arc segment 213 can enter the first space 1213, and the fan 3 drives the air flow to pass through the air flow channels formed by the first bending segment 211 and the second bending segment 221, the first straight segment 212 and the second straight segment 222, the second straight plate segment 12122 and the second arc segment 223, and the first straight plate segment 12121 and the second inner wall 1222 in sequence. One side of the air flow channel is composed of the first bending segment 211, the first straight segment 212, the second straight plate segment 12122 and the first straight plate segment 12121; the other side of the air flow channel is composed of the second bending segment 221, the second straight segment 222, the second arc segment 223 and the second inner wall 1222. Among them, the first straight segment 212, the second straight plate segment 12122 and the first straight plate segment 12121 form a smooth broken line, and the second arc segment 223 and the second inner wall 1222 form a smooth curve, so that the air flow can flow more smoothly, which is beneficial to the air flow to blow forward along the air flow channel.

[0077] As Figure 6 , Figures 9 - 10 , Figure 12 As shown, in some specific examples, when the air conditioner is in the second air outlet state S2, one side of the air flow channel is the first bending segment 211, the first straight segment 212, a part of the first arc segment 213, the second straight plate segment 12122 and the first straight plate segment 12121; the other side of the air flow channel is the second bending segment 221, the second straight segment 222 and the second inner wall 1222. Among them, the second arc segment 223 is located in the second space 1223, and the second straight segment 222 and the second inner wall 1222 are located or approximately located on the same straight line, so that the air flow can flow more smoothly, which is beneficial to the air flow to blow to both sides along the air flow channel.

[0078] As Figure 6 , Figures 9 - 10 , Figure 13 As shown, in some specific examples, when the air conditioner is in the third air outlet state S3, one side of the air flow channel is the first bending segment 211, the first straight segment 212, a part of the first arc segment 213 and the first inner wall 1212; the other side of the air flow channel is the second bending segment 221, the second straight segment 222, a part of the second arc segment 223 and the second inner wall 1222.

[0079] As Figure 6 , Figure 9 and Figure 10As shown, according to some embodiments of the present invention, an arcuate inlet 26 is formed between one ends of the first arcuate section 213 and the second arcuate section 223 facing the air duct inlet 23. A housing inlet 124 is formed between one ends of the first inner wall 1212 and the second inner wall 1222 close to the arcuate inlet 26. A housing outlet 125 is formed between one ends of the first inner wall 1212 and the second inner wall 1222 away from the arcuate inlet 26. The housing inlet 124 is larger than the arcuate inlet 26, and the housing outlet 125 is smaller than the air duct outlet 24. Specifically, along the air flow direction, the air flow sequentially passes through the air duct inlet 23, the arcuate inlet 26, the air duct outlet 24, and the housing outlet 125. Thus, the second housing 12 can move more smoothly, which is beneficial to stable rotation.

[0080] As Figure 2 , Figures 14 - 20 As shown, according to some embodiments of the present invention, the second housing 12 includes a first housing part e, a second housing part f, and a third housing part g. The second housing part f is located between the first housing part e and the third housing part g. The housing air duct 123 is provided on the second housing part f. The first housing part e and the third housing part g are fixed to the first housing 11. The first driving device 4 can be installed on the first housing part e; alternatively, the first driving device 4 can be installed on the second housing part f; alternatively, the first driving device 4 can be installed on the first housing part e and the second housing part f; the first driving device 4 can drive the second housing part f to rotate around the rotation axis. This structural design is simple and ingenious, and there is no need to set more connection mechanisms and fixing mechanisms to realize the installation of the second housing part f.

[0081] As Figure 2 , Figures 14 - 20 , by way of example, the first housing part e, the second housing part f, and the third housing part g are sequentially arranged along the vertical direction to form the second housing 12. The projection surfaces of the first housing part e, the second housing part f, and the third housing part g on the horizontal plane can be the same. The second housing part f can rotate independently, or the first housing part e, the second housing part f, and the third housing part g can rotate as a whole; the projection surfaces of the first housing part e, the second housing part f, and the third housing part g on the horizontal plane can be different. The first driving device 4 is provided on the first housing part e or the third housing part g, and the second housing part f rotates independently.

[0082] As Figures 1 - 2 , Figures 14 - 20As shown, according to some embodiments of the present invention, the air conditioner indoor unit 100 further includes a wind deflector 51 and a second driving device. The wind deflector 51 is disposed on the second housing 12, and the second driving device can drive the wind deflector 51 to open or close the housing air outlet 125. By providing the wind deflector 51 and the second driving device, when the air conditioner indoor unit 100 is not operating, including the internal structure of the air conditioner indoor unit 100, foreign objects can be prevented from entering; the air flow direction can also be guided to present air outlets in different directions; when the wind deflector 51 is a draft-free wind deflector 51, the comfort of the blowing can also be improved.

[0083] As Figure 19 and Figure 20 shown, exemplarily, the wind deflector 51 is a horizontal air guide vane 511. The horizontal air guide vane 511 is installed at the housing air outlet 125 of the second housing 12. The horizontal air guide vanes 511 are multiple and are arranged at intervals in the up and down direction. The horizontal air guide vanes 511 can present different air outlet angles in the up and down direction.

[0084] As Figures 15 - 18 shown, exemplarily, the wind deflector 51 is a vertical wind deflector 512. The vertical wind deflector 512 can rotate to close the housing air outlet 125 of the second housing part f. Optionally, the vertical wind deflector 512 can be one. Or optionally, the vertical wind deflectors 512 can also be multiple and are arranged at intervals in the left and right direction. The vertical wind deflectors 512 can present different air outlet angles in the left and right direction.

[0085] According to some embodiments of the present invention, there are multiple second housings 12, and the air duct components 2 correspond to the second housings 12 one by one. The air outlets 24 of the air supply channels 20 of different air duct components 2 blow air in different directions, thereby increasing the air outlet range of the air conditioner indoor unit 100.

[0086] As Figure 14 shown, exemplarily, there are two second housings 12, and the two second housings 12 are symmetrically arranged on the air conditioner indoor unit 100 with respect to the symmetry axis S4. When the air conditioner indoor unit 100 is in the second air outlet state S2, one second housing air outlet 125 blows air to the left, and the other second housing air outlet 125 blows air to the right.

[0087] As Figure 4 and Figure 5 shown, according to some embodiments of the present invention, multiple air duct components 2 can be connected as a whole to facilitate the installation and disassembly operations of the air duct components 2.

[0088] An air conditioner according to another embodiment of the present invention includes the air conditioner indoor unit 100 of the above embodiment.

[0089] Further, the air conditioner further includes an air conditioner outdoor unit, and the air conditioner outdoor unit is connected to the air conditioner indoor unit 100.

[0090] An air conditioner according to an embodiment of the present invention, the fan 3 of the indoor unit 100 of the air conditioner can drive air to form an air flow and drive the air flow to flow through the connecting air duct and the housing air duct 123 in sequence. The second housing 12 rotates around the rotation axis under the drive of the first drive device 4 so that the housing air outlet 125 of the housing air duct 123 blows air in different directions. By the rotation of the second housing 12, the positions of the housing air duct 123 and the housing air outlet 125 are changed; the housing air outlet 125 of the housing air duct 123 can face the front side of the indoor unit 100 of the air conditioner, so that the indoor unit 100 of the air conditioner blows air forward; the housing air outlet 125 of the housing air duct 123 can face both sides of the indoor unit 100 of the air conditioner, so that the indoor unit 100 of the air conditioner blows air to both sides, which increases the air supply range of the indoor unit 100 of the air conditioner.

[0091] The following is based on Figures 1 to 20 Describe a specific embodiment.

[0092] The air conditioner includes an indoor unit 100 of the air conditioner and an outdoor unit of the air conditioner.

[0093] The indoor unit of the air conditioner includes a first housing 11, a second housing 12, an air duct component 2, a fan 3, a first drive device 4, a wind deflector 51 and a heat exchange component 6.

[0094] The first housing 11 and the second housing 12 together form the outer shell of the indoor unit 100 of the air conditioner. The first housing 11 includes a top cover 111, a rear shell 112 and a chassis 113, and the rear shell 112 has an air inlet 1121 of the indoor unit of the air conditioner.

[0095] The second housing 12 includes a first housing part e, a second housing part f and a third housing part g, and the first housing part e, the second housing part f and the third housing part g are arranged in sequence in the up-down direction. The first drive device 4 is provided in the first housing part e, and the first drive device 4 can drive the second housing part f to rotate. The second housing part f can rotate around the rotation axis, and at the same time, the housing air outlet 124 on the second housing part f rotates so that the housing air outlet 124 blows air in different directions. When the housing air outlet 125 faces both sides of the indoor unit 100 of the air conditioner, there are two second housings 12. One second housing 12 includes one housing air outlet 125, and each housing air outlet 125 blows air to one side of the indoor unit 100 of the air conditioner and the indoor unit 100 of the air conditioner can blow air to both sides at the same time. There are two second housings 12, and the two second housings 12 are symmetrically arranged on the indoor unit 100 of the air conditioner with respect to the symmetry axis S4. When the indoor unit 100 of the air conditioner is in the second air outlet state S2, one second housing air outlet 125 blows air to the left, and the other second housing air outlet 125 blows air to the right.

[0096] Specifically, there are air flow channels inside the first housing 11 and the second housing 12, and the air flow channels are formed by combining the housing air duct 123 in the second housing 12 and the air supply channel 20 in the air duct component 2. Driven by the fan 3, air enters the air conditioner indoor unit 100 from the air inlet 1121 of the air conditioner indoor unit on the rear housing 112. When passing through the heat exchange component 6, the air flow exchanges heat with the heat exchange component 6, and enters the air supply channel 20 of the air duct component 2 through the air duct inlet 23. The air flow then flows into the housing air inlet 124 from the air duct outlet 24 of the air duct component 2, and after passing through the housing air duct 123, it is blown out through the housing air outlet 125.

[0097] When the air conditioner indoor unit 100 is in the first air outlet state S1, the first arc segment 213 can enter the first space 1213, and the fan 3 drives the air flow to sequentially pass through the air flow channel composed of the first bending segment 211 and the second bending segment 221, the first straight segment 212 and the second straight segment 222, the second straight plate segment 12122 and the second arc segment 223, and the first straight plate segment 12121 and the second inner side wall 1222. One side of the air flow channel is composed of the first bending segment 211, the first straight segment 212, the second straight plate segment 12122 and the first straight plate segment 12121; the other side of the air flow channel is composed of the second bending segment 221, the second straight segment 222, the second arc segment 223 and the second inner side wall 1222. Among them, the first straight segment 212, the second straight plate segment 12122 and the first straight plate segment 12121 form a smooth broken line, and the second arc segment 223 and the second inner side wall 1222 form a smooth curve, which can make the air flow flow more smoothly and is conducive to the air flow blowing forward along the air flow channel.

[0098] In some specific examples, when the air conditioner is in the second air outlet state S2, one side of the air flow channel is the first bending segment 211, the first straight segment 212, a part of the first arc segment 213, the second straight plate segment 12122 and the first straight plate segment 12121; the other side of the air flow channel is the second bending segment 221, the second straight segment 222 and the second inner side wall 1222. Among them, the second arc segment 223 is located in the second space 1223, and the second straight segment 222 and the second inner side wall 1222 are on the same straight line, which can make the air flow flow more smoothly and is conducive to the air flow blowing to both sides along the air flow channel.

[0099] In some specific examples, when the air conditioner is in the third air outlet state S3, one side of the air flow channel is the first bending segment 211, the first straight segment 212, a part of the first arc segment 213 and the first inner side wall 1212; the other side of the air flow channel is the second bending segment 221, the second straight segment 222, a part of the second arc segment 223 and the second inner side wall 1222.

[0100] According to some embodiments of the present invention, an arcuate inlet 26 is formed between one ends of the first arcuate section 213 and the second arcuate section 223 facing the air duct inlet 23. A housing inlet 124 is formed between one ends of the first inner wall 1212 and the second inner wall 1222 close to the arcuate inlet 26. A housing outlet 125 is formed between one ends of the first inner wall 1212 and the second inner wall 1222 away from the arcuate inlet 26. The housing inlet 124 is larger than the arcuate inlet 26, and the housing outlet 125 is smaller than the air duct outlet 24. Specifically, along the air flow direction, the air flow sequentially passes through the air duct inlet 23, the arcuate inlet 26, the air duct outlet 24, and the housing outlet 125. Thus, the second housing 12 can move more smoothly, which is beneficial to stable rotation.

[0101] The air deflector 51 is a horizontal air deflector blade 511, and the horizontal air deflector blade 511 is installed at the housing outlet 125 of the second housing 12. The horizontal air deflector blades 511 are multiple and arranged at intervals, and the horizontal air deflector blades 511 can present different air outlet angles in the up and down directions.

[0102] Exemplarily, the air deflector 51 is a vertical air deflector 512, and the vertical air deflector 512 can rotate to close the housing outlet 125 of the second housing part f.
