[0045] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0046] Hereinafter, an air conditioner indoor unit 100 and an air conditioner according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0047] like Figure 2 and Figure 10 As shown, the air conditioner indoor unit 100 according to an embodiment of the present invention includes a casing 1 , an air duct component 2 , a plurality of first drive assemblies 5 , a plurality of second drive assemblies 6 and an indoor heat exchanger 4 .

[0048] Specifically, refer to Figure 2 and Figure 10 The front surface of the casing 1 is provided with a plurality of air outlets 1231 arranged at intervals in the upper and lower directions, and the left side wall 121 and / or the right side wall 122 of the casing 1 are provided with a first indoor air inlet 1211; the duct component 2 is arranged in the casing 1, and the duct component 2 includes a plurality of duct shells 24 with air duct openings 241 and a plurality of main fans 23, and the plurality of duct shells 24 are respectively rotatably arranged in the casing 1, and the plurality of duct shells 24 are arranged one-to-one correspondingly to the plurality of air outlets 1231, and the plurality of main fans 23 are one-to-one and rotatably installed in the plurality of duct shells 24; the plurality of first drive assemblies 5 are arranged one-to-one correspondingly to the plurality of main fans 23 to drive the plurality of main fans 23 to rotate independently; the plurality of second drive assemblies 6 are respectively matched with the plurality of duct shells 24 one-to-one to drive the plurality of duct shells 24 to rotate; the indoor heat exchanger 4 is arranged in the casing 1 and is located between the duct component 2 and the first indoor air inlet 1211.

[0049] It is understood that the first drive assembly 5 can drive the main fan 23 to rotate, and the rotation of the main fan 23 can drive the airflow from the first indoor air inlet 1211 to the air duct component 2. During this period, the airflow exchanges heat with the indoor heat exchanger 4, causing the airflow to cool or heat up before entering the air duct component 2, and then flowing from the air duct opening 241 to the air outlet 1231, and then flowing into the room to achieve the purpose of cooling or heating the room. In addition, since the air duct housing 24 has an air duct opening 241, the air duct opening 241 can rotate with the air duct housing 24 within the housing 1. Therefore, the air duct housing 24 can rotate to different positions to have different air outlet directions. Furthermore, the rotatable air duct housing 24 relative to the housing 1 can facilitate the adjustment of the air outlet direction of the air conditioner indoor unit 100 to meet the air demand of different users. The second drive assembly 6 can drive the air duct housing 24 to rotate, thereby facilitating the rotation of the air duct housing 24.

[0050] The left side wall 121 and the right side wall 122 of the housing 1 can each be provided with a first indoor air inlet 1211. This can increase the area of ​​the first indoor air inlet 1211, thereby increasing the amount of air intake, thereby providing more heat exchange airflow for the air conditioner indoor unit 100, and improving the cooling or heating performance. Of course, the first indoor air inlet 1211 can also be provided only on the left side wall 121 of the housing 1; the first indoor air inlet 1211 can also be provided only on the right side wall 122 of the housing 1. There are no excessive restrictions on the location and number of the first indoor air inlets 1211. As long as the first indoor air inlet 1211 is provided on the left side wall 121 and / or the right side wall 122, it falls within the scope of protection of the present invention.

[0051] Among them, the front surface of the casing 1 is provided with multiple air outlets 1231 to increase the air outlet volume, thereby providing more airflow (including cold airflow, hot airflow or fresh airflow) for the room. The multiple air outlets 1231 are spaced apart in the upper and lower directions of the front surface of the casing 1 to facilitate the arrangement of the multiple air outlets 1231. The multiple air outlets 1231 can be provided with multiple air duct shells 24 and multiple main fans 23 to guide the airflow to different air outlets 1231 respectively. The multiple first drive assemblies 5 are arranged in a one-to-one correspondence with the multiple main fans 23 to drive the multiple main fans 23 to rotate independently, and the multiple second drive assemblies 6 are respectively matched with the multiple air duct shells 24 to drive the multiple air duct shells 24 to rotate independently. Thus, the main fans 23 can rotate independently; the air duct shells 24 can also rotate independently; and the main fans 23 and the air duct shells 24 can also rotate together. In addition, the multiple main fans 23 can rotate independently of each other, thereby enabling some of the main fans 23 to operate while others are not; the multiple air duct housings 24 can rotate independently of each other, thereby enabling some of the air duct housings 24 to operate while others are not. This allows the air volume to be adjusted according to user needs.

[0052] In the prior art, the air duct housing of most indoor air conditioner units is fixed to the housing. When air is blown out of the duct housing, the air outlet angle is adjusted by louvers, resulting in a single method for adjusting the air outlet direction. Furthermore, the air outlets of these indoor air conditioner units cannot selectively output air, but can only output air from both outlets or neither outlet, failing to meet users' diverse air volume requirements.

[0053] In the air conditioner indoor unit 100 according to an embodiment of the present invention, the duct housing 24 is rotatably disposed within the housing 1, allowing the duct housing 24 to be positioned at different positions within the housing 1. The different positions of the duct housing 24 within the housing 1 allow air to flow out of the interior space of the duct housing 24 at different angles. Thus, the rotation of the duct housing 24 within the housing 1 can adjust the airflow direction of the duct housing 24, thereby meeting the user's different airflow requirements. Furthermore, the multiple first drive assemblies 5 are arranged in a one-to-one correspondence with the multiple main fans 23 to drive the multiple main fans 23 to rotate independently, and the multiple second drive assemblies 6 are respectively arranged in a one-to-one correspondence with the multiple duct housings 24 to drive the multiple duct housings 24 to rotate independently. Thus, the multiple main fans 23 can rotate independently of each other, thereby achieving a situation where some main fans 23 are in operation while others are inoperative. The multiple duct housings 24 can also rotate independently of each other, thereby achieving a situation where some of the duct housings 24 are in operation while others are inoperative. Thus, the air volume can be adjusted according to user needs.

[0054] In some embodiments of the present invention, Figure 10 As shown, each second drive assembly 6 includes a motor 61, a gear 62, and an annular ring gear 63. The motor 61 is provided on the housing 1. The gear 62 cooperates with the motor 61 to be driven to rotate by the motor 61. The ring gear 63 is fixed to the corresponding air duct housing 24 and meshes with the gear 62. It is understood that the housing 1 can support the motor 61, the motor 61 can drive the gear 62 to rotate, and the gear 62 meshes with the ring gear 63 to drive the ring gear 63 to rotate. As a result, the ring gear 63 can drive the air duct housing 24 to rotate.

[0055] refer to Figure 10 According to some embodiments of the present invention, the ring gear 63 may be an inner ring gear 63, which allows the gear 62 to be located on the inner side of the ring gear 63 when installed, thereby reducing the overall volume of the ring gear 63 and the gear 62, and further reducing the volume of the second drive assembly 6, thereby saving internal space for the air-conditioning indoor unit 100 and reducing the structural volume of the air-conditioning indoor unit 100.

[0056] Combine Figure 10In some embodiments of the present invention, the air conditioner indoor unit 100 further includes a plurality of protective rings 113, which are fixed to the casing 1. At least one axial end of each air duct component 2 is clearance-fitted with the protective ring 113, so that the air duct component 2 can rotate relative to the protective ring 113, and the protective ring 113 can provide support and a rotation environment for the air duct component 2.

[0057] According to some embodiments of the present invention, Figure 10 As shown, the air-conditioning indoor unit 100 also includes an air outlet grille 25. An air outlet grille 25 is provided at the air duct opening 241 of each air duct shell 24. Thus, while facilitating air outlet, the air outlet grille 25 can protect the internal components of the air duct shell 24, preventing dust and the like from entering the air duct shell 24 and damaging the internal components of the air duct shell 24, such as the main motor 61. Moreover, the air outlet grille 25 can also prevent the user from putting his hand into the air duct shell 24 through the air duct opening 241 and touching the main motor 61, which may cause danger.

[0058] Combine Figure 10 In some embodiments of the present invention, the housing 1 may include a main frame 11 and a shell 12, the main frame 11 is arranged in the shell 12, the air outlet 1231 and the first indoor air inlet 1211 are arranged on the shell 12, the air duct component 2 is mounted on the main frame 11, and the axial ends of the air duct shell 24 are rotatably supported on the main frame 11. It can be understood that the main frame 11 can be used to support the air duct component 2 and provide a rotation environment for the air duct shell 24, and the shell 12 can be arranged outside the main frame 11, so that the shell 12 can protect the main frame 11 and support the air duct component 2. Moreover, the shell 12 can facilitate the arrangement of the air outlet 1231 and the first indoor air inlet 1211, and provide an environment for the arrangement of the air outlet 1231 and the first indoor air inlet 1211.

[0059] According to some embodiments of the present invention, Figure 9-10 As shown, the main frame 11 includes a skeleton 111 and a fixing frame 112. The skeleton 111 is provided with a plurality of first mounting cavities 1111. A mounting opening 1112 is provided on one side of each first mounting cavity 1111. The air duct housing 24 is rotatably mounted in the first mounting cavity 1111 through the mounting opening 1112. A fixing frame 112 is fixed at each mounting opening 1112, and a portion of the second drive assembly 6 is fixed on the fixing frame 112. The first mounting cavity 1111 can accommodate the air duct housing 24, facilitating the arrangement and rotation of the air duct housing 24. The mounting opening 1112 can facilitate the installation of the air duct housing 24. The fixing frame 112 is provided at the mounting opening 1112 to limit the air duct housing 24 and prevent the air duct housing 24 from falling off from the mounting opening 1112. At the same time, the fixing frame 112 can also be used to support part of the second drive assembly 6.

[0060] Combine Figure 10 In some embodiments of the present invention, the main frame 11 further comprises a second mounting cavity 1113, which is located below the plurality of first mounting cavities 1111. The housing 12 further comprises a sewage exhaust air inlet 126 and a sewage exhaust air outlet 127. A sewage exhaust fan 32 is housed within the second mounting cavity 1113 and communicates with the sewage exhaust air inlet 126 and the sewage exhaust air outlet 127, respectively. The second mounting cavity 1113 accommodates the sewage exhaust fan 32. The location of the second mounting cavity 1113 below the plurality of first mounting cavities 1111 facilitates the placement of the sewage exhaust fan 32, which drives polluted air from the sewage exhaust air inlet 126 to the sewage exhaust air outlet 127. Alternatively, the sewage exhaust air outlet 127 can be connected to the outside of the room via a connecting pipe, thereby allowing polluted air to be discharged from the sewage exhaust air outlet 127 to the outside of the room, thereby purifying the indoor air.

[0061] In some embodiments of the present invention, reference Figure 5-Figure 6 , a fresh air inlet 124 and a fresh air outlet 125 can also be provided on the casing 1; the air-conditioning indoor unit 100 can also include a ventilation system 3, the ventilation system 3 includes a sewage exhaust fan 32 and a fresh air fan 31, and the internal space of the air duct shell 24 is connected with the first indoor air inlet 1211 and the air outlet 1231 respectively; the ventilation system 3 is arranged in the casing 1, the air inlet end of the sewage exhaust fan 32 is connected with the sewage exhaust air inlet 126, the air outlet end of the sewage exhaust fan 32 is connected with the sewage exhaust air outlet 127, the air inlet end of the fresh air fan 31 is connected with the fresh air inlet 124, and the air outlet end of the fresh air fan 31 is connected with the fresh air outlet 125.

[0062] It is understood that the housing 1 can provide an installation environment for the ventilation system 3. The sewage exhaust fan 32 can drive the dirty air flow from the sewage exhaust air inlet 126 to the air inlet end of the sewage exhaust fan 32, then to the air outlet end of the sewage exhaust fan 32, and then to the sewage exhaust air outlet 127; the fresh air fan 31 can drive the air flow from the fresh air inlet 124 to the air inlet end of the fresh air fan 31, then to the air outlet end of the fresh air fan 31, and then to the fresh air outlet 125. As an achievable method, the sewage exhaust outlet 127 and the fresh air inlet 124 can both be connected to the outside through a connecting pipe, thereby allowing the dirty air to be discharged to the outside from the sewage exhaust outlet 127, while the fresh air inlet 124 can introduce outdoor fresh air into the air conditioner indoor unit 100 and then blow it into the room, thereby purifying the indoor air.

[0063] Here, the sewage exhaust fan 32 can work alone, thereby exhausting the dirty air in the room to the outside, making the indoor air clean and fresh; the fresh air fan 31 can also work alone, thereby introducing outdoor fresh air into the room, also making the indoor air clean and fresh; of course, the sewage exhaust fan 32 and the fresh air fan 31 can also work at the same time. While the sewage exhaust fan 32 exhausts the dirty air in the room to the outside, the fresh air fan 31 introduces outdoor fresh air into the room, thereby making the indoor air cleaning ability stronger and making the indoor air fresher.

[0064] In some embodiments of the present invention, the exhaust fan 32 and the fresh air fan 31 can be configured to start and stop synchronously, so that while the exhaust fan 32 discharges the dirty air in the room to the outside, the fresh air fan 31 introduces fresh air from the outside into the room, thereby making the indoor air purification ability stronger and the indoor air fresher.

[0065] According to some embodiments of the present invention, Figure 7 The exhaust fan 32 and the fresh air fan 31 can share a single motor 61. This allows the exhaust fan 32 to exhaust dirty air from the room while the fresh air fan 31 draws fresh air from the outside into the room. This enhances the indoor air purification capability and makes the indoor air fresher. Furthermore, sharing the motor 61 for both exhaust and fresh air eliminates the need for a single motor 61, thereby reducing the production cost of the air conditioner indoor unit 100 and also conserving energy during the operation of the ventilation system 3.

[0066] like Figure 6 As shown, in some embodiments of the present invention, the fresh air outlet 125 and the air outlet 1231 are the same vent, and the air outlet end of the fresh air fan 31 is connected to the air duct housing 24. It can be understood that the fresh air outlet 125 and the air outlet 1231 are the same vent, which can eliminate the need for processing and manufacturing the fresh air outlet 125, reducing manufacturing costs. The air outlet end of the fresh air fan 31 is connected to the air duct housing 24, so that the fresh air fan 31 can drive the outdoor fresh air to flow into the interior space of the air duct housing 24, and then flow from the air duct housing 24 to the air outlet 1231, and then flow into the room.

[0067] According to some embodiments of the present invention, the outlet end of the fresh air blower 31 supplies air toward the air inlet side or the air outlet side of the indoor heat exchanger 4. Specifically, when the outlet end of the fresh air blower 31 supplies air toward the air inlet side of the indoor heat exchanger 4, the fresh air blower 31 drives the outdoor fresh air to flow toward the air inlet side of the indoor heat exchanger 4. At this time, the indoor air enters the air inlet side of the indoor heat exchanger 4 from the first indoor air inlet 1211. After the outdoor fresh air and the indoor air are mixed and heat-exchanged with the indoor heat exchanger 4, they flow from the air duct housing 24 to the air outlet 1231 and are blown into the room. Of course, the compressor that controls the flow of refrigerant in the indoor heat exchanger 4 may not be working. At this time, the air at normal temperature is mixed with the outdoor fresh air and flows from the air duct housing 24 to the air outlet 1231 and is blown into the room. When the outlet end of the fresh air blower 31 is delivering air toward the outlet side of the indoor heat exchanger 4, the fresh air blower 31 drives the outdoor fresh air to flow toward the outlet side of the indoor heat exchanger 4. At this time, the airflow that has exchanged heat with the indoor heat exchanger 4 is blown out from the outlet side of the indoor heat exchanger 4 and mixed with the outdoor fresh air. When the indoor heat exchanger 4 is in a refrigeration cycle, the cold airflow blown out from the outlet side of the indoor heat exchanger 4 encounters the outdoor fresh air at room temperature, which produces mist. This can satisfy the blowing preferences of some users. In summary, both can achieve the goal of delivering outdoor fresh air into the room to refresh the indoor air.

[0068] Combine Figure 3 and Figure 8 In some embodiments of the present invention, the ventilation system 3 can be located in the second installation cavity 1113, that is, the ventilation system 3 is located below the first installation cavity 1111, that is, below the air duct component 2, thereby facilitating the arrangement of the sewage exhaust fan 32 and the fresh air fan 31 in the air-conditioning indoor unit 100, and also facilitating the air outlet end of the fresh air fan 31 to supply air toward the air inlet side or the air outlet side of the indoor heat exchanger 4, thereby shortening the flow path of the outdoor fresh air and saving the driving energy of the fresh air fan 31.

[0069] In some embodiments of the present invention, Figure 1 and Figure 6 As shown, the main air duct 21 is defined by the main fan 23 and the inner wall of the air duct housing 24, and the auxiliary air duct 22 is defined between the outer wall of the air duct housing 24 and the inner wall of the housing 1. The outlet end of the auxiliary air duct 22 is arranged adjacent to the outlet end of the main air duct 21, and the auxiliary air duct 22 is connected to the fresh air outlet 125. The outlet end of the fresh air fan 31 is connected to the auxiliary air duct 22 to supply air toward the auxiliary air duct 22. The fresh air fan 31 can drive outdoor fresh air to flow from the fresh air inlet 124 to the auxiliary air duct 22. The main air duct 21 can be used to transport airflow (including cooling airflow, heating airflow, or normal temperature airflow) into the room. When the outlet end of the main air duct 21 transports airflow into the room, it can bring out the fresh air from the auxiliary air duct 22. In this way, outdoor fresh air can be introduced into the room, making the indoor air fresher and improving the user comfort of the air conditioner indoor unit 100.

[0070] According to some embodiments of the present invention, reference Figure 1-Figure 2 The air duct component 2 cooperates with the casing 1 to define a main air duct 21 and an auxiliary air duct 22 that are arranged at intervals. The air outlet end of the auxiliary air duct 22 is arranged adjacent to the air outlet end of the main air duct 21. The main air duct 21 is respectively connected to the air outlet 1231 and the first indoor air inlet 1211, and the auxiliary air duct 22 is connected to the air outlet 1231. The main fan 23 is arranged in the main air duct 21; the indoor heat exchanger 4 is arranged in the casing 1 and is located between the first indoor air inlet 1211 and the main fan 23.

[0071] It is understood that the main fan 23 is arranged in the main air duct 21 and can drive the air flow from the first indoor air inlet 1211 to the air outlet 1231, and then flow into the room. In the process of the air flow flowing from the first indoor air inlet 1211 to the air outlet 1231, it passes through the indoor heat exchanger 4 and exchanges heat with the indoor heat exchanger 4, causing the temperature of the air flow to drop or rise, thereby allowing the air flow flowing into the room to cool or heat. Because the air outlet end of the auxiliary air duct 22 is arranged adjacent to the air outlet end of the main air duct 21, when the air is discharged from the air outlet end of the main air duct 21, the air flow in the auxiliary air duct 22 will be carried out of the auxiliary air duct 22, thereby increasing the air outlet volume of the air outlet 1231, so that the cooling or heating effect of the air conditioner indoor unit 100 is better.

[0072] In addition, the main fan 23 can work alone. At this time, the cooling air or heating air flows into the room through the main air duct 21 and the auxiliary air duct 22; the fresh air fan 31 can also work alone. At this time, the outdoor fresh air flows into the room through the auxiliary air duct 22; the main fan 23 and the fresh air fan 31 can also work at the same time. At this time, the cooling air or heating air flows into the room through the main air duct 21, and the outdoor fresh air flows into the room through the auxiliary air duct 22. Of course, when the main fan 23 and the fresh air fan 31 work at the same time, the compressor that controls the flow of refrigerant in the indoor heat exchanger 4 may not work. At this time, the main fan 23 drives the normal temperature airflow to blow out from the main air duct 21 while driving the outdoor fresh air from the auxiliary air duct 22 to blow out.

[0073] In some embodiments of the present invention, Figure 2-Figure 3As shown, the main fan 23 is disposed within the duct housing 24. The main fan 23 and the inner wall of the duct housing 24 define a main duct 21, and the outer wall of the duct housing 24 and the inner wall of the housing 1 define an auxiliary duct 22. It is understood that the main fan 23 disposed within the duct housing 24 can facilitate defining the main duct 21 together with the inner wall of the duct housing 24. The main fan 23 disposed within the main duct 21 drives the airflow toward the main duct 21, then flows out of the duct housing 24 from the duct opening 241 of the main duct 21, flows toward the air outlet 1231 of the housing 1, and flows into the room. When the airflow flows out of the duct opening 241, a negative pressure is formed at the duct opening 241. As a result, the airflow within the auxiliary duct 22 flows toward the duct opening 241 and then flows into the room together with the airflow within the main duct 21. In addition, the outer wall of the duct housing 24 and the inner wall of the housing 1 can facilitate defining the auxiliary duct 22.

[0074] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, there can be multiple main air ducts 21, and an outlet end of an auxiliary air duct 22 is correspondingly set on the outer side of the outlet end of each main air duct 21. It can be understood that multiple main air ducts 21 can increase the air intake and outlet volumes, thereby improving the cooling or heating capacity of the air-conditioning indoor unit 100; in addition, multiple main air ducts 21 can drive multiple auxiliary air ducts 22 to discharge air. When the fresh air fan 31 is not working, the air discharge of multiple auxiliary air ducts 22 can further increase the air outlet volume, further improving the cooling or heating effect of the air-conditioning indoor unit 100; when the fresh air fan 31 is working, the air discharge of multiple auxiliary air ducts 22 can increase the amount of outdoor fresh air entering the room, making the indoor air fresher.

[0075] In some embodiments of the present invention, the main fan 23 is a centrifugal fan. The characteristic of the centrifugal fan is that the air flow can enter from the axial direction of the centrifugal fan and be blown out from the radial direction of the centrifugal fan. The main fan 23 adopts a centrifugal fan to facilitate the air intake from one axial side or both axial sides of the main fan 23, and then blown out from the radial direction of the main fan 23, that is, the air duct opening 241.

[0076] like Figure 4 As shown, according to some embodiments of the present invention, a second indoor air inlet 1281 is provided on the casing 1, and the second indoor air inlet 1281 is connected to the auxiliary air duct 22, wherein the indoor air can also enter the auxiliary air duct 22 from the second indoor air inlet 1281, thereby increasing the air volume in the auxiliary air duct 22. When air is discharged from the air outlet end of the main air duct 21, the air flow in the auxiliary air duct 22 will be brought out of the auxiliary air duct 22, thereby increasing the air outlet volume of the air outlet 1231, so that the cooling or heating effect of the air-conditioning indoor unit 100 is better.

[0077] In some embodiments of the present invention, a first switch door is provided on the casing 1, and the first switch door is used to open or close the second indoor air inlet 1281. Thus, when the first switch door opens the second indoor air inlet 1281, the air flow can flow from the second indoor air inlet 1281 to the auxiliary air duct 22; when the first switch door closes the second indoor air inlet 1281, the first switch door can block the second indoor air inlet 1281, thereby protecting the internal components of the casing 1 and preventing dust and the like from entering the casing 1 and damaging the components inside the casing 1; moreover, the first switch door can also prevent the user from putting his hand into the casing 1 through the second indoor air inlet 1281 and causing danger.

[0078] According to some embodiments of the present invention, Figure 2 As shown, there can be two indoor heat exchangers 4, and the two indoor heat exchangers 4 are respectively arranged on the left and right sides of the air duct component 2. Therefore, an indoor heat exchanger 4 can be set at the first indoor air inlet 1211 of the left side wall 121 and the first indoor air inlet 1211 of the right side wall 122 of the casing 1, thereby increasing the heat exchange area and improving the cooling or heating capacity, so that more cold air flow or hot air flow can enter the room, thereby improving the cooling or heating performance of the air-conditioning indoor unit 100.

[0079] In some embodiments of the present invention, Figure 2 As shown, the shell 12 may include a front panel 123 and a back panel 128, and multiple air outlets are arranged on the front panel 123 at intervals along the up and down directions. The front panel 123 and the back panel 128 are arranged at opposite ends of the main frame 11, and a second indoor air inlet 1281 is opened on the back panel 128.

[0080] An air conditioner according to an embodiment of the present invention includes the air conditioner indoor unit 100 as described above.

[0081] According to an embodiment of the air conditioner of the present invention, the air duct housing 24 is rotatably disposed within the housing 1, allowing the air duct housing 24 to be positioned at different positions within the housing 1. The different positions of the air duct housing 24 within the housing 1 allow air to flow out of the interior space of the air duct housing 24 from different angles. Thus, the rotation of the air duct housing 24 within the housing 1 can adjust the air outlet direction of the air duct housing 24, thereby meeting the different air outlet requirements of the user. Furthermore, the plurality of first drive assemblies 5 are arranged in a one-to-one correspondence with the plurality of main fans 23 to drive the plurality of main fans 23 to rotate independently, and the plurality of second drive assemblies 6 are respectively arranged in a one-to-one correspondence with the plurality of air duct housings 24 to drive the plurality of air duct housings 24 to rotate independently. Thus, the plurality of main fans 23 can rotate independently of each other, thereby achieving a situation where some of the main fans 23 are in operation while others are not. The plurality of air duct housings 24 can rotate independently of each other, thereby achieving a situation where some of the air duct housings 24 are in operation while others are not. Thus, the air volume can be adjusted according to user needs.
