[0055] The following description, with reference to the accompanying drawings, describes an air conditioner indoor unit 100 according to an embodiment of the present invention. The air conditioner indoor unit 100 can be a wall-mounted air conditioner indoor unit.

[0056] Reference Figures 1-17 As shown, the indoor unit 100 of the air conditioner according to the embodiment of the present utility model may include: a housing assembly 10, an air duct assembly 30, an indoor fan 40, and an indoor heat exchanger 50.

[0057] Specifically, the housing assembly 10 has an air inlet 111 and multiple air outlets 121. Outside airflow flows into the indoor unit 100 through the air inlet 111, and airflow within the indoor unit 100 flows to the outside through the air outlets 121. The duct assembly 30 is movably disposed within the housing assembly 10; for example, the duct assembly 30 is rotatable, movable, or both rotatable and movable within the housing assembly 10. Furthermore, in some embodiments, such as... Figure 1 As shown, the indoor unit 100 of the air conditioner also includes a chassis 20, which is located inside the housing assembly 10. The chassis 20 can be used to install components such as the air duct assembly 30, the indoor fan 40, and the indoor heat exchanger 50.

[0058] For example, in some specific embodiments, such as Figure 1 As shown, the air duct assembly 30 is rotatably mounted on the chassis 20 within the housing assembly 10, and the air duct assembly 30 can be... Figures 2-3 Rotate to the state shown Figures 4-5 The state shown Figures 6-7 The state shown Figures 8-9 The state shown Figures 10-12 The state shown.

[0059] The air duct assembly 30 defines an air duct 311, which is a channel for airflow. The inlet 312 of the air duct 311 is connected to the air inlet section 111, and the outlet 313 of the air duct 311 can be selectively connected to at least one of a plurality of air outlet sections 121, so that the airflow flowing into the indoor unit 100 of the air conditioner through the air inlet section 111 flows into the air duct 311 through the inlet 312 and flows to the air outlet section 121 through the outlet 313 to flow to the outside.

[0060] Both the indoor fan 40 and the indoor heat exchanger 50 are housed within the casing assembly 10. The indoor fan 40 is located at the inlet 312 of the air duct 311, and the indoor heat exchanger 50 is positioned between the indoor fan 40 and the air inlet 111 in the airflow direction. The indoor fan 40 can be a cross-flow impeller, which can rotate under the drive of a motor. The indoor heat exchanger 50 can be an evaporator, so that the airflow flowing from the air inlet 111 to the inlet 312 first passes through the indoor heat exchanger 50 for heat exchange, and in conjunction with the indoor fan 40, heats up as much as possible all the airflow flowing to the inlet 312, which can turn cold air into hot air or hot air into cold air. The heat-exchanged airflow enters the air duct 311 and flows out from the air outlet 121 through the outlet 313, so as to realize the cooling or heating function of the indoor unit 100 for the outside.

[0061] The plurality of air outlets 121 include a first air outlet 1211, a second air outlet 1212 and a third air outlet 1213 arranged in sequence in the first direction F1 and having different air outlet directions. The first direction F1 can extend along a straight line, a curve or an irregular shape, which makes it easy to adjust the setting position of the plurality of air outlets 121.

[0062] The multiple air outlets 121 include a first air outlet 1211, a second air outlet 1212, and a third air outlet 1213. The relatively small number of air outlets 121 reduces the space occupied by these outlets on the housing assembly 10, allowing for more airflow directions within a limited space. This improves the structural compactness of the indoor unit 100 while achieving multi-directional airflow. For example… Figures 2-3 As shown, the airflow can be discharged along the airflow direction corresponding to all the first air outlets 1211, for example... Figures 4-5 As shown, the airflow can be directed along the airflow direction corresponding to a portion of the first air outlet 1211 and a portion of the second air outlet 1212, for example... Figures 6-7 As shown, the airflow can be discharged along the airflow direction corresponding to all the second air outlets 1212, such as... Figures 8-9 As shown, the airflow can be discharged along the corresponding airflow direction of a portion of the second air outlet 1212 and a portion of the third air outlet 1213, for example... Figures 10-12 As shown, the airflow can be discharged along the airflow direction corresponding to all the third air outlets 1213.

[0063] In addition, the dimensions of the first air outlet 1211, the second air outlet 1212 and the third air outlet 1213 along the first direction F1 can be flexibly adjusted according to the air outlet requirements, so as to flexibly adjust the air outlet direction that the air conditioner indoor unit 100 can achieve.

[0064] During the movement of the air duct assembly 30 relative to the housing assembly 10, the outlet 313 of the air duct 311 can selectively be opposite and connected to at least a portion of at least one of the plurality of air outlets 121. For example, the outlet 313 can be sequentially opposite and connected to two adjacent air outlets 121. Different air outlets 121 correspond to different air outlet directions, and multi-directional air outlets can be achieved through multiple air outlets 121, which helps to meet user needs.

[0065] In some related technologies, the indoor unit of an air conditioner is equipped with a rotating air guide vane at the outlet of the air duct. This vane rotates relative to the air duct assembly to achieve multi-directional airflow. However, the outlet position of the air duct is fixed, and the rotating air guide vane has a limited range of motion, resulting in a small airflow distribution area that cannot meet users' needs for more directional airflow. Furthermore, during the process of guiding airflow, the rotating air guide vane obstructs the airflow, increasing airflow loss, reducing the output airflow, and easily creating airflow vortices at the air duct outlet, increasing noise and resulting in a poor user experience.

[0066] This application achieves multi-directional airflow by moving the air duct assembly 30 relative to the housing assembly 10, so that the outlet 313 of the air duct 311 is opposite to different air outlets 121. By changing the position of the air duct 311 relative to the housing assembly 10, the position of the outlet 313 can be adjusted, directly changing the airflow direction at the outlet 313. This results in a wide airflow range, easily meeting users' needs for airflow in more directions. Furthermore, directly changing the position of the outlet 313 to change the airflow direction minimizes airflow obstruction and airflow loss, increasing the airflow volume and reducing noise, thus improving the user experience.

[0067] like Figure 13 As shown, the indoor unit 100 of the air conditioner includes a first mode, a second mode, and a third mode. (As...) Figures 2-3 As shown, in the first mode, the duct assembly 30 opens the first air outlet 1211 so that the outlet 313 of the duct 311 is opposite to and connected to the first air outlet 1211. The duct assembly 30 blocks the second air outlet 1212 and the third air outlet 1213. By blocking the second air outlet 1212 and the third air outlet 1213, which are not opposite to the outlet 313, the airflow in the duct 311 can flow out more from the first air outlet 1211 opposite to the outlet 313, reducing the possibility of airflow escaping in other directions. This helps to increase the airflow volume in the air outlet direction corresponding to the first air outlet 1211 opposite to the outlet 313, thereby improving the cooling or heating efficiency of the indoor unit 100 for the corresponding air outlet direction of the external space.

[0068] In this application, the corresponding air outlet 121 refers to the air outlet 121 that corresponds to the required air outlet direction. For example, the user can adjust the outlet 313 to be opposite to and connected to the corresponding air outlet 121 so that air can be discharged through the corresponding air outlet 121.

[0069] like Figures 6-7 As shown, in the second mode, the duct assembly 30 opens the second air outlet 1212 so that the outlet 313 of the duct 311 is opposite to and connected to the second air outlet 1212, while the duct assembly 30 blocks the first air outlet 1211 and the third air outlet 1213. Similarly, this allows more airflow within the duct 311 to exit from the second air outlet 1212 opposite to the outlet 313, which helps to increase the airflow volume in the air outlet direction corresponding to the second air outlet 1212, thereby improving the cooling or heating efficiency of the indoor unit 100 for the corresponding air outlet direction and the corresponding external space.

[0070] like Figures 10-12 As shown, in the third mode, the duct assembly 30 opens the third air outlet 1213 so that the outlet 313 of the duct 311 is opposite to and connected to the third air outlet 1213. The duct assembly 30 blocks the first air outlet 1211 and the second air outlet 1212. Similarly, this allows more airflow in the duct 311 to flow out from the third air outlet 1213 opposite to the outlet 313, which helps to increase the airflow volume in the air outlet direction corresponding to the third air outlet 1213, thereby improving the cooling or heating efficiency of the indoor unit 100 for the corresponding air outlet direction and the corresponding external space.

[0071] According to the embodiment of the present utility model, the air conditioner indoor unit 100, by movably disposing the air duct assembly 30 on the housing assembly 10, can directly change the position of the outlet 313 of the air duct 311 to change the airflow direction, thereby realizing multi-directional air outlet of the air conditioner indoor unit 100, with a large air outlet range and low air outlet noise. In the first mode, the air outlet volume of the first air outlet 1211 is large, in the second mode, the air outlet volume of the second air outlet 1212 is large, and in the third mode, the air outlet volume of the third air outlet 1213 is large, which is conducive to improving the cooling or heating efficiency of the air conditioner indoor unit 100 and providing a better user experience.

[0072] In some embodiments of this utility model, such as Figures 1-12 As shown, the third air outlet 1213 is located in front of and above the first air outlet 1211, so that in the first mode, the air outlet direction corresponding to the first air outlet 1211 is further back and lower than in the third mode, while in the third mode, the air outlet direction corresponding to the third air outlet 1213 is further forward and higher.

[0073] like Figures 2-3As shown, the first mode is the heating mode, which makes the hot air flow downwards and the air outlet direction is closer to the wall, which is conducive to generating a stronger Coanda effect, making the hot air jet more convergent and increasing the air volume. The hot air has better grounding and rolls a longer distance along the ground. Hot air is lighter than cold air, so the hot air flowing to the outside will rise under the action of gravity. The temperature rise rate of the foot warmer and the room is increased, and the uniformity of the indoor temperature is significantly improved.

[0074] like Figures 10-12 As shown, the third mode is the cooling mode, which makes the cold air flow upward and descend under the action of gravity, which can accelerate the indoor air circulation and significantly improve the indoor cooling speed and temperature uniformity.

[0075] In some embodiments, such as Figures 1-12 As shown, the first air outlet 1211 and the third air outlet 1213 are both air outlet openings with the same shape as the outlet 313 of the air duct 311, so that the airflow from the outlet 313 to the first air outlet 1211 and the third air outlet 1213 can flow directly to the outside. The airflow is not easily obstructed at the first air outlet 1211 and the third air outlet 1213, which helps to increase the air volume at the first air outlet 1211 and the third air outlet 1213 and improve the heating efficiency and cooling efficiency of the indoor unit 100 of the air conditioner.

[0076] In some embodiments of this utility model, such as Figures 1-12 As shown, the second air outlet 1212 includes a diffuser plate, which has the same shape as the outlet 313 of the air duct 311. The diffuser plate is provided with multiple spaced-apart diffuser holes. When the indoor unit 100 of the air conditioner is turned on, the large airflow flowing from the outlet 313 to the second air outlet 1212 can be divided into multiple smaller airflows by the multiple diffuser holes, so as to disperse the concentrated airflow into many fine air filaments, making the airflow more uniform and facilitating the realization of windless airflow, making the user feel more comfortable.

[0077] When the indoor unit 100 of the air conditioner is in standby mode, the outlet 313 of the air duct 311 can be covered by the air diffuser, which reduces the possibility of external dust or small stones and other impurities entering the air duct 311 and damaging the internal structure of the indoor unit 100, thus helping to protect the indoor unit 100 of the air conditioner.

[0078] like Figures 6-7 As shown, the second mode is a windless mode. When the indoor unit 100 of the air conditioner is turned on, the airflow from the outlet 313 of the air duct 311 is dispersed by the diffuser at the second air outlet 1212, which reduces the airflow speed and intensity, achieving windless airflow. When the indoor unit 100 of the air conditioner is in standby mode, the outlet 313 can be covered by the second air outlet 1212 to protect the indoor unit 100 of the air conditioner.

[0079] In some embodiments, such as Figures 1-12As shown, the second air outlet 1212 is located in front of and above the first air outlet 1211, so that in the first mode, the air outlet direction corresponding to the first air outlet 1211 is further back and lower than in the second mode, while in the second mode, the air outlet direction corresponding to the second air outlet 1212 is further forward and higher.

[0080] like Figures 2-3 As shown, the first mode is the heating mode. The air outlet direction is lower than that of the second mode, and the air outlet direction is closer to the wall. The hot air flowing to the outside will rise under the action of gravity, which increases the temperature rise rate of the foot warmer and the room, and significantly improves the uniformity of the indoor temperature.

[0081] In some embodiments, such as Figures 1-12 As shown, the first air outlet 1211 is an air outlet opening with the same shape as the outlet 313 of the air duct 311, so that the airflow from the outlet 313 to the first air outlet 1211 can flow directly to the outside without being easily obstructed, which is conducive to increasing the air volume at the first air outlet 1211 and improving the heating efficiency of the air conditioning indoor unit 100.

[0082] The indoor unit 100 of the air conditioner also includes a low-frequency mode, for example... Figure 13 As shown, the indoor unit 100 of the air conditioner also includes a low-wind-feel mode for heating. For example... Figures 4-5 As shown, in the low-wind heating mode, the air duct assembly 30 blocks part of the first air outlet 1211, part of the second air outlet 1212 and all of the third air outlet 1213, and opens part of the first air outlet 1211 and part of the second air outlet 1212, so that the outlet 313 of the air duct 311 is opposite to and connected to part of the first air outlet 1211 and part of the second air outlet 1212.

[0083] Part of the airflow exiting outlet 313 flows directly out through the first air outlet 1211, while the other part is dispersed by the diffuser of the second air outlet 1212 before flowing out. This reduces the airflow speed and intensity to a certain extent, achieving a gentle breeze. Furthermore, the airflow direction is lower than in the second mode. During heating operation of the indoor unit 100, the hot air flows downwards and rises under gravity, which not only increases the rate of indoor temperature rise but also achieves a gentle breeze during heating, improving user comfort.

[0084] In some embodiments of this utility model, such as Figures 1-12 As shown, the third air outlet 1213 is located in front of and above the second air outlet 1212, so that in the second mode, the air outlet direction corresponding to the second air outlet 1212 is further back and lower than in the third mode, while in the third mode, the air outlet direction corresponding to the third air outlet 1213 is further forward and higher.

[0085] like Figures 10-12As shown, the third mode is the cooling mode. The air outlet direction is higher than that of the second mode, causing the cold air to flow upwards. The cold air descends under the influence of gravity, which can accelerate the indoor air circulation and significantly improve the indoor cooling speed and temperature uniformity.

[0086] In some embodiments, such as Figures 1-12 As shown, the third air outlet 1213 is an air outlet opening with the same shape as the outlet 313 of the air duct 311, so that the airflow from the outlet 313 to the third air outlet 1213 can flow directly to the outside without being easily obstructed, which helps to increase the air volume at the third air outlet 1213 and improve the heating efficiency of the air conditioning indoor unit 100.

[0087] The indoor unit 100 of the air conditioner also includes a low-frequency mode, for example... Figure 13 As shown, the indoor unit 100 of the air conditioner also includes a weak cooling fan mode. (As shown...) Figures 8-9 As shown, in the cooling weak wind mode, the air duct assembly 30 blocks the first air outlet 1211, part of the second air outlet 1212, and part of the third air outlet 1213, and opens part of the second air outlet 1212 and part of the third air outlet 1213, so that the outlet 313 of the air duct 311 is arranged opposite to and connected to part of the second air outlet 1212 and part of the third air outlet 1213.

[0088] Part of the airflow exiting outlet 313 flows directly out through the third air outlet 1213, while the other part is dispersed by the diffuser of the second air outlet 1212 before flowing out. This reduces the airflow speed and intensity to a certain extent, achieving a weak airflow. Furthermore, the airflow direction is higher than in the second mode. During the cooling operation of the indoor unit 100, the cold air descends under gravity, which not only increases the rate of indoor temperature drop but also achieves a weak airflow, improving user comfort.

[0089] In some embodiments of this utility model, such as Figures 1-12 and Figures 14-15 As shown, the air duct assembly 30 includes an air duct component 31 and a baffle plate 32, with the air duct component 31 defining an air duct 311. For example, in some embodiments, such as... Figures 1-12 As shown, the air duct component 31 includes an air duct volute, which has an air duct volute tongue, an upper air duct diffuser section, and a lower air duct diffuser section. The air duct 311 is defined inside the air duct volute.

[0090] In some embodiments, such as Figures 1-12As shown, the baffle plate 32 is connected to the side of the air duct component 31 away from the indoor fan 40, and the outlet 313 of the air duct 311 is formed on the baffle plate 32. The baffle plate 32 is used to open or block the air outlet 121. By opening the corresponding air outlet 121 through the outlet 313 on the baffle plate 32, and by blocking the air outlet 121 that is not opposite to the outlet 313 through the solid part of the baffle plate 32, more airflow in the air duct 311 can flow out from the air outlet 121 opposite to the outlet 313, thereby increasing the airflow volume in the air outlet direction corresponding to the air outlet 121 opposite to the outlet 313, thus improving the cooling or heating efficiency of the indoor unit 100 for the corresponding air outlet direction and meeting user needs.

[0091] For example, in some embodiments, such as Figures 2-3 As shown, in the first mode, the outlet 313 on the baffle 32 is opposite to the first air outlet 1211 to open the first air outlet 1211, and the solid portion of the baffle 32 blocks the second air outlet 1212 and the third air outlet 1213. Figures 6-7 As shown, in the second mode, the outlet 313 on the baffle 32 is opposite to the second air outlet 1212 to open the second air outlet 1212, and the solid portion of the baffle 32 blocks the first air outlet 1211 and the third air outlet 1213. Figures 10-12 As shown, in the third mode, the outlet 313 on the baffle 32 is opposite to the third air outlet 1213 to open the third air outlet 1213, and the solid portion of the baffle 32 blocks the first air outlet 1211 and the second air outlet 1212. Figures 4-5 As shown, in the low-wind heating mode, the outlet 313 on the baffle 32 is opposite to a portion of the first air outlet 1211 and a portion of the second air outlet 1212 to open a portion of the first air outlet 1211 and a portion of the second air outlet 1212, while the baffle 32 blocks the remaining portions of the first air outlet 1211, the remaining portions of the second air outlet 1212, and all of the third air outlet 1213. Figures 8-9 As shown, in the cooling weak wind mode, the outlet 313 on the baffle 32 is opposite to part of the second air outlet 1212 and part of the third air outlet 1213 to open part of the second air outlet 1212 and part of the third air outlet 1213, while the baffle 32 blocks other parts of the second air outlet 1212, other parts of the third air outlet 1213 and all of the first air outlet 1211.

[0092] In some embodiments, such as Figures 1-12As shown, the housing assembly 10 includes an air outlet panel 12, on which multiple air outlets 121 are disposed. The air outlet panel 12 is an arc-shaped plate, with the first direction F1 being the arc-shaped extension direction of the air outlet panel 12. This arrangement of the multiple air outlets 121 along the arc-shaped extension direction of the air outlet panel 12 allows for smoother connection between adjacent air outlets 121. During the process of the outlet 313 moving from connecting with one air outlet 121 to connecting with another adjacent air outlet 121 as it moves with the air duct assembly 30, the change in airflow direction is more natural and less abrupt. The airflow is smoother during the change of airflow direction, resulting in a better multi-directional airflow effect.

[0093] The baffle plate 32 is an arc-shaped plate corresponding to the shape of the air outlet panel 12, so that the baffle plate 32 can completely block the air outlet 121 that is opposite to the baffle plate 32 in the current state, reducing the possibility of airflow flowing out from the air outlet 121 opposite to the baffle plate 32, which is conducive to increasing the air volume of the air outlet 121 corresponding to the air outlet 313, thereby improving the cooling or heating efficiency of the air conditioner indoor unit 100 to the corresponding air outlet direction of the corresponding external space.

[0094] In some embodiments, such as Figures 1-12 As shown, the housing assembly 10 also includes a face frame 11, and an air outlet panel 12 is disposed on the face frame 11. For example, the air outlet panel 12 is detachably disposed on the face frame 11, making the housing assembly 10 easy to manufacture.

[0095] Both the face frame 11 and the air outlet panel 12 extend in the left and right directions along their length. The arc-shaped extension direction of the air outlet panel 12 is a direction that gradually extends upward from back to front, so that the air outlet panel 12 covers the bottom and lower front part of the face frame 11, making it convenient to place the air outlet 121 at the bottom and lower front part of the face frame 11, so that air can be discharged forward and downward through the air outlet 121.

[0096] Multiple air outlets 121 are arranged from back to front and gradually upward. The outlet 313 is at least partially connected to at least one of the multiple air outlets 121, so that the air conditioner indoor unit 100 can discharge air downward, discharge air forward, and discharge air downward and forward, etc., so as to realize the cooling or heating function of the air conditioner indoor unit 100 to the space from its lower side to its front side, and meet the user's usage needs.

[0097] For example, in some embodiments, such as Figures 2-5 As shown, for Figures 2-3 In the state shown, the air conditioner indoor unit 100 rotates a certain distance along the arc-shaped extension direction of the air outlet panel 12, i.e., the first direction F1, so that the outlet 313 of the air duct 311 rotates forward and upward, and the air conditioner indoor unit 100 can be transformed into... Figures 4-5 The state shown.

[0098] In some embodiments, such as Figures 1-12As shown, the housing assembly 10 also includes a front panel 13, which covers the upper front side of the front frame 11. The air outlet panel 12 covers the bottom and lower front side of the front frame 11, and the lower end of the front panel 13 is connected to the air outlet panel 12 by an arc. The front panel 13 can be shaped differently from the air outlet panel 12, allowing for a larger installation space on the inner side of the air conditioner indoor unit 100 at the front panel 13, facilitating the installation of other components. Furthermore, the arc transition between the front panel 13 and the air outlet panel 12 facilitates demolding and manufacturing, reduces sharp edges on the surface of the air conditioner indoor unit 100, and reduces the risk of injury to users, thus improving safety.

[0099] In some embodiments, the air outlet panel 12 and the front panel 13 are integrally formed, making the air outlet panel 12 and the front panel 13 more robust and durable in overall structure, less prone to relative movement or even separation, and more practical.

[0100] In some embodiments of this utility model, such as Figures 1-12 and Figures 14-15 As shown, the wind deflector 32 includes a first wind deflector 321 and a second wind deflector 322, and in the first direction F1, the outlet 313 of the air duct 311 is located between the first wind deflector 321 and the second wind deflector 322. Figures 2-3 As shown, in the first mode, the outlet 313 of the air duct 311 is opposite to and connected to the first air outlet 1211, and the second air baffle 322 completely blocks the second air outlet 1212 and the third air outlet 1213. Figures 6-7 As shown, in the second mode, the outlet 313 of the air duct 311 is opposite to and connected to the second air outlet 1212. The first windbreak 321 completely blocks the first air outlet 1211, and the second windbreak 322 completely blocks the third air outlet 1213. Figures 10-12 As shown, in the third mode, the outlet 313 of the air duct 311 is disposed opposite to and connected to the third air outlet 1213, and the first windbreak 321 blocks the entire first air outlet 1211 and the second air outlet 1212.

[0101] Through the first windbreak 321 and the second windbreak 322 on both sides of the outlet 313 along the first direction F1, during the movement of the air duct assembly 30, the first windbreak 321 can block the outlet 313 on one side along the first direction F1 (e.g., during the movement of the air duct assembly 30). Figures 1-12 The air outlet 121 (located on the lower side of the outlet 313) is blocked by the second windbreak 322 from the other side of the outlet 313 along the first direction F1 (e.g., Figures 1-12 The air outlet 121 (on the upper side of the outlet 313313 shown) can achieve partitioned blocking of multiple air outlets 121 along the arrangement direction of multiple air outlets 121, i.e., the first direction F1, so as to realize partitioned air outlet and increase the air volume at the corresponding air outlet 121.

[0102] In some embodiments, such as Figures 1-12 As shown, the outlet 313, the first air outlet 1211, the second air outlet 1212, and the third air outlet 1213 of the air duct 311 have the same dimensions in the first direction F1, so that the outlet 313 of the air duct 311 can be opposite to all the first air outlets 1211 to discharge air along the air discharge direction corresponding to all the first air outlets 1211, the outlet 313 can also be opposite to all the second air outlets 1212 to discharge air along the air discharge direction corresponding to all the second air outlets 1212, and the outlet 313 can also be opposite to all the third air outlets 1213 to discharge air along the air discharge direction corresponding to all the second air outlets 1212.

[0103] With the outlet 313 of the air duct 311 facing all the first air outlets 1211, the second windbreak 322 blocks the second air outlets 1212 and all the third air outlets 1213, allowing the airflow within the air duct 311 to exit completely along the airflow direction corresponding to the first air outlets 1211. With the outlet 313 of the air duct 311 facing all the second air outlets 1212, the first windbreak 321 blocks all the first air outlets 1211, and the second windbreak 322 blocks all the third air outlets 1213, allowing the airflow within the air duct 311 to exit completely along the airflow direction corresponding to the second air outlets 1212. With the outlet 313 of the air duct 311 facing all the third air outlets 1213, the first baffle 321 blocks the first air outlet 1211 and all the second air outlets 1212, so that the airflow in the air duct 311 can be completely discharged along the air outlet direction corresponding to the third air outlet 1213. This helps to increase the air volume in the air outlet direction corresponding to the air outlet 121 facing the outlet 313, thereby improving the cooling or heating efficiency of the indoor unit 100 of the air conditioner to the corresponding external space in the corresponding air outlet direction and meeting user needs.

[0104] The size of the first wind deflector 321 in the first direction F1 is greater than or equal to the sum of the sizes of the first air outlet 1211 and the second air outlet 1212 in the first direction F1. Similarly, the size of the second wind deflector 322 in the first direction F1 is greater than or equal to the sum of the sizes of the second air outlet 1212 and the third air outlet 1213 in the first direction F1. In the first direction F1, the size of the first wind deflector 321 is large enough to completely block the first air outlet 1211 and the second air outlet 1212, and the size of the second wind deflector 322 is large enough to completely block the second air outlet 1212 and the third air outlet 1213. This reduces the possibility of airflow exiting from the area of ​​the air outlet 121 that is not opposite to the outlet 313 of the duct 311. This helps to increase the airflow volume in the air outlet direction corresponding to the outlet 121 opposite to the outlet 313, thereby improving the cooling or heating efficiency of the indoor unit 100 for the corresponding external space in the air outlet direction and meeting user needs.

[0105] In some embodiments of this utility model, such as Figures 1-12 and Figures 14-15 As shown, the first direction F1 is the extension direction of an arc, so that multiple air outlets 121 are arranged along the extension direction of the arc, making the connection between adjacent air outlets 121 smoother. When the outlet 313 moves from being connected to one air outlet 121 to being connected to another adjacent air outlet 121 as it moves with the air duct assembly 30, the change in the airflow direction is more natural and not abrupt. The airflow is smoother during the change of airflow direction, and the effect of multi-directional airflow is better.

[0106] The duct assembly 30 is rotatably mounted on the chassis 20, and the center of the arc containing the first direction F1 is located on the rotation axis of the duct assembly 30. During the rotation of the duct assembly 30, the outlet 313 can move along the arrangement direction of the multiple air outlets 121, i.e., the first direction F1, so that the outlet 313 can connect with the multiple air outlets 121 in sequence. This helps to improve the control accuracy of the connection between the outlet 313 and the corresponding air outlet 121, and meets the user's air outlet requirements for any air outlet 121 corresponding to the air outlet direction.

[0107] In some embodiments, such as Figures 1-12 As shown, the air outlet panel 12 is an arc-shaped plate, and the first direction F1 is the arc extension direction of the air outlet panel 12. The center of the arc where the first direction F1 is located is located on the rotation axis of the air duct assembly 30, so that the central axis of the cylindrical surface where the air outlet panel 12 is located coincides with the rotation axis of the air duct assembly 30, which is beneficial to improve the control accuracy of the connection between the outlet 313 and the corresponding air outlet 121.

[0108] In some embodiments, such as Figures 1-12 As shown, the rotation axis of the air duct assembly 30 coincides with the rotation axis of the indoor fan 40, allowing the air duct assembly 30 to rotate around the indoor fan 40. This facilitates the design of the relative positions of the air duct assembly 30 and the indoor fan 40, reducing the possibility of positional interference between the air duct assembly 30 and the indoor fan 40, and improving the structural compactness of the internal components of the air conditioning indoor unit 100.

[0109] In some embodiments, such as Figures 14-16 As shown, the indoor fan 40 is a cross-flow impeller, and the air duct component 31 has a fixed seat on each of its left and right sides. The cross-flow impeller can be rotatably connected to the air duct component 30 through the fixed seat. One of the fixed seats has a small notch and is almost a complete circle, which facilitates the installation of the cross-flow impeller and makes it difficult for the cross-flow impeller to detach from the fixed seat.

[0110] In some embodiments, such as Figure 12 and Figure 17As shown, the central angle α of the area occupied by the multiple air outlets 121 on the air outlet panel 12 is less than 90°. If α is too large, it will cause the duct assembly 30 to have an excessively large range of motion, which in turn will cause the duct assembly 30 to encroach on other components within the air conditioner indoor unit 100, affecting the working efficiency of the air conditioner indoor unit 100. For example, it may encroach on the installation space of the indoor heat exchanger 50, reducing the heat exchange area of ​​the indoor heat exchanger 50 and thus decreasing the working efficiency of the air conditioner indoor unit 100. Alternatively, if the range of motion of the duct assembly 30 is too large, the overall volume of the air conditioner indoor unit 100 needs to be increased to make room for the movement of the duct assembly 30, which will increase the cost of the air conditioner indoor unit 100.

[0111] This application allows 'a' to be less than 90°, which enables multi-directional airflow while improving the structural compactness of the components within the indoor unit 100, thereby increasing the operating efficiency and reducing the cost of the indoor unit 100. Furthermore, since the indoor unit 100 typically supplies air downwards and forwards, 'a' being less than 90° satisfies the airflow angle requirements of the indoor unit 100. For example, 'a' can be 50°, 70°, or 89°.

[0112] In some embodiments of this utility model, such as Figure 1 and Figures 14-16 As shown, the indoor unit 100 of the air conditioner also includes a drive assembly 60, which includes a drive motor 61 and a transmission mechanism 62. The drive motor 61 and the duct assembly 30 are connected by the transmission mechanism 62. The drive assembly 60 is used to drive the movement of the duct assembly 30. The drive motor 61 can be a stepper motor, AC motor, DC motor, or other types of motor. The transmission mechanism 62 can be a gear and rack assembly, a slide rail and slider assembly, a ball screw, etc. The transmission mechanism 62 transmits the driving force of the drive motor 61 to the duct assembly 30 to drive the duct assembly 30 to move. This allows for flexible adjustment of the relative positions of the drive motor 61 and the duct assembly 30, making the installation positions of the drive assembly 60 and the duct assembly 30 more flexible to adapt to the installation positions of other structures within the indoor unit 100, thereby improving the structural compactness of the components within the indoor unit 100.

[0113] In some embodiments, such as Figure 1 and Figures 14-16 As shown, the transmission mechanism 62 includes a gear 621 and a rack 622 that mesh with each other. The rack 622 extends along a first direction F1. One of the gear 621 and the rack 622 is located on the chassis 20 or the housing assembly 10, and the other is located on the air duct assembly 30. For example... Figure 1 and Figures 14-16 As shown, gear 621 and drive motor 61 are mounted together on chassis 20, and rack 622 is mounted on air duct assembly 30.

[0114] Gear 621 rotates under the drive of drive motor 61, thereby driving rack 622 to move along the first direction F1, making duct assembly 30 movable relative to chassis 20. Through the meshing transmission of gear 621 and rack 622, the driving force of drive motor 61 is transmitted to duct assembly 30, achieving high transmission accuracy. This improves the motion accuracy of duct assembly 30, allowing it to move precisely until the outlet 313 of duct 311 connects with the corresponding air outlet 121, thus meeting the user's needs for airflow from different directions.

[0115] In some embodiments of this utility model, such as Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figures 11-12 As shown, the housing assembly 10 has a groove 122 extending along the first direction F1 on the side facing the baffle 32, and the baffle 32 is slidably engaged with the groove 122. The groove 122 guides the movement of the baffle 32, allowing the air duct assembly 30 to move to a state where the outlet 313 is opposite to and connected to the corresponding air outlet 121. In this state, the baffle 32 can more accurately block other air outlets 121, which helps to increase the air volume in the air outlet direction corresponding to the air outlet 121.

[0116] The movement of the air duct assembly 30 can be controlled electronically. For example, when the air duct assembly 30 moves to the state where the outlet 313 is opposite to and connected to the corresponding air outlet 121, the air duct assembly 30 can be stopped. Alternatively, the air duct assembly 30 can be limited by a mechanical structure.

[0117] For example, in some embodiments, such as Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figures 11-12 As shown, the two ends of the slide 122 along the first direction F1 are a first closed end 1221 and a second closed end 1222, respectively. With the baffle plate 32 abutting against the first closed end 1221, the outermost air outlet 121 in the first direction F1 faces the outlet 313 of the air duct 311, and the baffle plate 32 blocks the remaining air outlets 121. With the baffle plate 32 abutting against the second closed end 1222, the outermost air outlet 121 in the first direction F1 faces the outlet 313 of the air duct 311, and the baffle plate 32 blocks the remaining air outlets 121.

[0118] The first closed end 1221 and the second closed end 1222 can limit the wind baffle 32, so that the air duct assembly 30 can move until the outlet 313 is opposite to and connected to the air outlets 121 at both ends of the first direction F1. This improves the control accuracy of the movement of the air duct assembly 30 and helps to improve the control accuracy of the connection between the outlet 313 and the air outlets 121 at both ends of the first direction F1.

[0119] For example, in some specific embodiments, such as Figure 3 As shown, with the first windbreak 321 abutting against the first closed end 1221 located on the lower side, the outlet 313 of the air duct 311 is opposite to and connected to all the lowermost first air outlets 1211, and the second windbreak 322 blocks the other air outlets 121. Figures 11-12 As shown, with the second windbreak 322 abutting against the second closed end 1222 located on the upper side, the outlet 313 of the air duct 311 is opposite to and connected to all the uppermost third air outlets 1213, and the first windbreak 321 blocks the other air outlets 121.

[0120] In some embodiments, such as Figures 1-12 and Figures 14-16 As shown, the air duct assembly 30 is rotatably mounted on the chassis 20. The central axis of the cylindrical surface where the air outlet panel 12 is located and the central axis of the cylindrical surface where the baffle plate 32 is located coincide with the rotation axis of the air duct assembly 30. During the rotation of the air duct assembly 30, the outlet 313 can sequentially connect with multiple air outlets 121 along the arrangement direction of the multiple air outlets 121, i.e., the arc-shaped extension direction. The baffle plate 32 can sequentially face multiple air outlets 121 along the arrangement direction of the multiple air outlets 121, i.e., the arc-shaped extension direction. This is beneficial to improving the control accuracy of the connection between the outlet 313 and the corresponding air outlet 121, as well as the control accuracy of the baffle plate 32 blocking other air outlets 121. It is also beneficial to increase the air volume at the corresponding air outlet 121, meeting the user's air outlet requirements for the corresponding air outlet direction of the corresponding air outlet 121.

[0121] In some embodiments, such as Figures 1-12 As shown, the dimension of the air outlet panel 12 in the arc-shaped extension direction is larger than that of the baffle 32 in the arc-shaped extension direction, and the central angle e corresponding to the air outlet panel 12 is less than 180°. In the arc-shaped extension direction, the dimension of the air outlet panel 12 is not too small, which would cause the baffle 32 to interfere with other components on the edge of the air outlet panel 12, and the dimension of the air outlet panel 12 is not too large, which would encroach on the installation space of other components, making the movement of the air duct assembly 30 smoother and the structure of the air conditioner indoor unit 100 more compact.

[0122] In some embodiments of this utility model, such as Figure 1 and Figure 12As shown, the indoor unit 100 of the air conditioner also includes a sway vane assembly 70, which is disposed in the duct assembly 30 and moves together with the duct assembly 30. The sway vane assembly 70 includes multiple sway vanes 71, which are oscillatingly disposed within the duct 311. By oscillating the sway vanes 71 relative to the duct 311, and by allowing the sway vanes 71 to move together with the duct assembly 30, the adjustment range of the airflow direction can be further increased to meet the user's demand for airflow from the indoor unit 100 in more directions.

[0123] In some embodiments, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figures 11-12 As shown, the indoor unit 100 of the air conditioner also includes a heater 51, which is located in the indoor heat exchanger 50. The heater 51 can be turned on when the indoor unit 100 of the air conditioner is in heating mode to provide auxiliary heating and improve heating efficiency.

[0124] The air conditioner according to the present invention is characterized by including an indoor unit 100 according to any one of claims 1-15. Since the indoor unit 100 according to the present invention has the aforementioned beneficial technical effects, the air conditioner according to the present invention, by movably distributing the air duct assembly 30 to the housing assembly 10, can directly change the position of the outlet 313 of the air duct 311 to change the airflow direction, thereby achieving multi-directional airflow from the indoor unit 100. This results in a large airflow range, low noise, and a large airflow volume from the first air outlet 1211 in the first mode, a large airflow volume from the second air outlet 1212 in the second mode, and a large airflow volume from the third air outlet 1213 in the third mode. This is beneficial for improving the cooling or heating efficiency of the indoor unit 100, and provides a better user experience.

[0125] The following describes in detail, with reference to the accompanying drawings, a specific embodiment of the air conditioner indoor unit 100 and the air conditioner according to the present invention. It is to be understood that the following description is merely illustrative and should not be construed as limiting the present invention.

[0126] like Figures 1-17 As shown, an indoor air conditioning unit 100 according to a specific embodiment of the present invention is used in an air conditioner. The indoor air conditioning unit 100 includes a housing assembly 10, a chassis 20, an air duct assembly 30, an indoor fan 40, an indoor heat exchanger 50, a drive assembly 60, and a louver assembly 70.

[0127] The housing assembly 10 includes a face frame 11, an air outlet panel 12, and a front panel 13. The front panel 13 covers the upper front side of the face frame 11, and the air outlet panel 12 covers the bottom and lower front side of the face frame 11. The lower end of the front panel 13 is connected to the air outlet panel 12 by an arc, and the air outlet panel 12 and the front panel 13 are integrally formed.

[0128] The front frame 11 has an air inlet 111. The air outlet panel 12 has multiple air outlets 121 arranged in a first direction F1, with different air outlet directions. The air outlet panel 12 is an arc-shaped panel, and the first direction F1 is the arc-shaped extension direction of the air outlet panel 12, making the first direction F1 an arc-shaped extension direction. The length direction of the front frame 11, the air outlet panel 12, and the front panel 13 extends in the left-right direction, and the first direction F1 is a direction that gradually extends upward from back to front.

[0129] Multiple air outlets 121 include a first air outlet 1211, a second air outlet 1212, and a third air outlet 1213 arranged sequentially in the first direction F1. In the first direction F1, the second air outlet 1212 is located between the first air outlet 1211 and the third air outlet 1213, and the third air outlet 1213 is located in front of and above the second air outlet 1212. The first air outlet 1211 and the third air outlet 1213 are both air outlet openings with the same shape as the outlet 313 of the air duct 311. The second air outlet 1212 includes a diffuser plate with the same shape as the outlet 313 of the air duct 311, and the diffuser plate is provided with multiple spaced-apart diffuser holes.

[0130] The chassis 20 is disposed within the housing assembly 10, and the air duct assembly 30 is rotatably disposed on the chassis 20. The air duct assembly 30 includes an air duct component 31 and a baffle plate 32, the air duct component 31 defining an air duct 311. The inlet 312 of the air duct 311 communicates with the air inlet 111, and the outlet 313 of the air duct 311 is optionally communicated with at least one of a plurality of air outlets 121.

[0131] Both the indoor fan 40 and the indoor heat exchanger 50 are located on the chassis 20. The indoor fan 40 is located at the inlet 312 of the air duct 311. In the direction of air flow, the indoor heat exchanger 50 is located between the indoor fan 40 and the air inlet 111.

[0132] The wind deflector 32 is connected to the side of the air duct component 31 away from the indoor fan 40. The outlet 313 of the air duct 311 is formed on the wind deflector 32. The wind deflector 32 is used to open or block the air outlet 121. The wind deflector 32 includes a first wind deflector 321 and a second wind deflector 322. In the first direction F1, the outlet 313 of the air duct 311 is located between the first wind deflector 321 and the second wind deflector 322, and the second wind deflector 322 is located in front of and above the first wind deflector 321.

[0133] The baffle plate 32 is an arc-shaped plate corresponding to the shape of the air outlet panel 12. When the air duct assembly 30 is rotated to the state where the outlet 313 of the air duct 311 is opposite to and connected to at least a portion of one of the air outlets 121, the baffle plate 32 blocks the portion of the plurality of air outlets 121 that is not opposite to the outlet 313.

[0134] The rotation axis of the indoor fan 40, the central axis of the cylindrical surface where the air outlet panel 12 is located, and the central axis of the cylindrical surface where the baffle plate 32 is located coincide with the rotation axis of the air duct assembly 30. The first direction F1 is the extension direction of an arc, and the center of the arc is located on the rotation axis of the air duct assembly 30.

[0135] In the first direction F1, the size of the air outlet panel 12 is larger than the size of the wind deflector 32. The central angle corresponding to the air outlet panel 12 is e, which is less than 180°. The central angle corresponding to the area occupied by the multiple air outlets 121 on the air outlet panel 12 is a, which is less than 90°. The central angle corresponding to the area occupied by the first air outlet 1211 on the air outlet panel 12 is b, the central angle corresponding to the area occupied by the second air outlet 1212 on the air outlet panel 12 is c, and the central angle corresponding to the area occupied by the third air outlet 121... 3. The central angle corresponding to the area occupied on the air outlet panel 12 is d, where b = c = d = a / 3. The dimensions of the first air outlet 1211, the second air outlet 1212, the third air outlet 1213, and the outlet 313 of the air duct 311 are the same. The dimension of the first wind deflector 321 is equal to the sum of the dimensions of the first air outlet 1211 and the second air outlet 1212, and the dimension of the second wind deflector 322 is equal to the sum of the dimensions of the second air outlet 1212 and the third air outlet 1213. During the movement of the air duct assembly 30, the relative proportions of the first air outlet 1211, the second air outlet 1212, and the third air outlet 1213 to the outlet 313 can be adjusted to achieve different airflow directions and airflow volumes in a weak wind mode.

[0136] The air outlet panel 12 has a groove 122 extending along a first direction F1 on the side facing the baffle plate 32, and the baffle plate 32 slidably engages with the groove 122. The two ends of the groove 122 along the first direction F1 are a first closed end 1221 and a second closed end 1222, respectively. When the first baffle portion 321 abuts against the lower first closed end 1221, the first air outlet 1211 faces the outlet 313 of the air duct 311, and the second baffle portion 322 blocks all of the second air outlet 1212 and all of the third air outlet 1213. When the second baffle portion 322 abuts against the upper second closed end 1222, the third air outlet 1213 faces the outlet 313 of the air duct 311, and the first baffle portion 321 blocks all of the first air outlet 1211 and all of the second air outlet 1212.

[0137] The drive assembly 60 includes a drive motor 61 and a transmission mechanism 62. The drive motor 61 and the air duct assembly 30 are connected by the transmission mechanism 62. The drive motor 61 drives the air duct assembly 30 to rotate. The transmission mechanism 62 includes a meshing gear 621 and a rack 622. The rack 622 extends along a first direction F1. The gear 621 is located on the chassis 20 and the rack 622 is located on the air duct assembly 30. The gear 621 can rotate under the drive of the drive motor 61, thereby driving the rack 622 to move along the first direction F1, causing the air duct assembly 30 to rotate relative to the chassis 20.

[0138] The sway blade assembly 70 is disposed on the air duct assembly 30 and rotates together with the air duct assembly 30. The sway blade assembly 70 includes a plurality of sway blades 71, which are swayably disposed in the air duct 311.

[0139] During the operation of the indoor unit 100 of the air conditioner, the outside airflow enters the interior of the indoor unit 100 through the air inlet 111 and then flows through the indoor heat exchanger 50 for heat exchange. Combined with the indoor fan 40, the airflow entering from the air inlet 111 is heat exchanged as much as possible. The heat-exchanged airflow enters the air duct 311 through the inlet 312 and flows out to the outside through the outlet 313 of the air duct 311 from the corresponding air outlet 121.

[0140] like Figure 13 As shown, the indoor unit 100 of the air conditioner includes a first mode, a second mode, a third mode and a low-wind mode. The low-wind mode includes a heating low-wind mode and a cooling low-wind mode. The first mode is the heating mode, the second mode is the cooling mode, and the third mode is the windless mode or the standby mode.

[0141] In the first mode, the air duct assembly 30 opens the first air outlet 1211 so that the outlet 313 of the air duct 311 is opposite to and connected to the first air outlet 1211, and the second air baffle 322 blocks the entire second air outlet 1212 and the entire third air outlet 1213.

[0142] In the second mode, the air duct assembly 30 opens the second air outlet 1212 so that the outlet 313 of the air duct 311 is opposite to and connected to the second air outlet 1212, the first wind deflector 321 blocks the entire first air outlet 1211, and the second wind deflector 322 blocks the entire third air outlet 1213.

[0143] In the third mode, the air duct assembly 30 opens the third air outlet 1213 so that the outlet 313 of the air duct 311 is opposite to and connected to the third air outlet 1213, and the first windbreak 321 blocks the entire first air outlet 1211 and the entire second air outlet 1212.

[0144] In the low-wind heating mode, the air duct assembly 30 blocks part of the first air outlet 1211, part of the second air outlet 1212 and all of the third air outlet 1213, and opens part of the first air outlet 1211 and part of the second air outlet 1212, so that the outlet 313 of the air duct 311 is opposite to and connected to part of the first air outlet 1211 and part of the second air outlet 1212.

[0145] In the cooling weak wind mode, the air duct assembly 30 blocks the first air outlet 1211, part of the second air outlet 1212, and part of the third air outlet 1213, and opens part of the second air outlet 1212 and part of the third air outlet 1213, so that the outlet 313 of the air duct 311 is arranged opposite to and connected to part of the second air outlet 1212 and part of the third air outlet 1213.

[0146] Starting with the first mode, the following describes the transitions between multiple modes of the indoor unit 100 during the rotation of the air duct assembly 30.

[0147] First, in the first mode, which is the heating mode, such as Figures 2-3 As shown, outlet 313 is disposed opposite to and connected to all first air outlets 1211. Second air baffle 322 blocks all second air outlets 1212 and all third air outlets 1213, so that airflow is discharged downward from the first air outlet 1211. The first air outlet 1211 is an air outlet opening with a large air volume and high heating efficiency.

[0148] Specifically, among the three air outlets 121, the air outlet direction corresponding to the first air outlet 1211 is the lowest. During heating operation, the outlet 313 is positioned opposite to and connected to all the first air outlets 1211 located at the lowest side, causing the hot air to be discharged downwards. The air outlet direction is closer to the wall, which is conducive to generating a stronger Coanda effect, making the hot air stream more convergent and increasing the air volume. The hot air has better ground penetration and a longer rolling distance along the ground. Hot air is lighter than cold air, so the hot air flowing to the outside will rise under the action of gravity, which increases the temperature rise rate of the foot warmer and the room, and significantly improves the uniformity of the indoor temperature.

[0149] Then, the air duct assembly 30 rotates along the first direction F1, and the indoor unit 100 of the air conditioner switches to a low-wind heating mode, such as... Figures 4-5As shown, outlet 313 is positioned opposite to and connected to the upper part of the first air outlet 1211 and the lower part of the second air outlet 1212. The first baffle 321 blocks other parts of the first air outlet 1211, and the second baffle 322 blocks other parts of the second air outlet 1212 and the entire third air outlet 1213. The second air outlet 1212 is a diffuser. This allows part of the airflow from outlet 313 to flow directly through the first air outlet 1211, while the other part is dispersed by the diffuser holes in the second air outlet 1212 before flowing out. This reduces the airflow velocity and intensity to a certain extent, achieving a weak draft. During heating operation, the airflow generally flows downwards, while the hot air rises under gravity, resulting in a larger airflow volume. This not only increases the rate of indoor temperature rise but also achieves a weak draft during heating, improving user comfort.

[0150] The air duct assembly 30 continues to rotate in the first direction F1, and the indoor unit 100 of the air conditioner switches to the second mode, such as... Figures 6-7 As shown, outlet 313 is positioned opposite to and connected to all second air outlets 1212. First baffle 321 blocks all first air outlets 1211, and second baffle 322 blocks all third air outlets 1213. When the indoor unit 100 is on, the second air outlets 1212 disperse the airflow from outlet 313 of the air duct 311, reducing the airflow speed and intensity, achieving a windless airflow. When the indoor unit 100 is in standby mode, the second air outlets 1212 cover outlet 313 to protect the indoor unit 100.

[0151] The air duct assembly 30 continues to rotate in the first direction F1, and the indoor unit 100 of the air conditioner switches to a low-wind cooling mode, such as... Figures 8-9 As shown, outlet 313 is positioned opposite to and connected to the upper part of the second air outlet 1212 and the lower part of the third air outlet 1213. The first windbreak 321 blocks all other parts of the first air outlet 1211 and the second air outlet 1212, and the second windbreak 322 blocks other parts of the third air outlet 1213. The third air outlet 1213 is an air outlet opening. This allows part of the airflow from outlet 313 to flow directly out through the third air outlet 1213, while the other part is dispersed by the second air outlet 1212 before flowing out. This reduces the airflow speed and intensity to a certain extent, achieving a weak, gentle airflow.

[0152] Specifically, among the three air outlets 121, the air outlet direction corresponding to the third air outlet 1213 is the highest, meaning that the airflow direction in the cooling weak draft mode is higher than in the first mode, heating weak draft mode, and second mode. During cooling operation, the airflow generally rises, while the cold air descends under gravity, resulting in a larger air volume. This not only improves the indoor cooling speed but also achieves a weak draft cooling effect, enhancing user comfort.

[0153] The air duct assembly 30 continues to rotate in the first direction F1, and the indoor unit 100 of the air conditioner switches to the third mode, such as... Figures 10-12 As shown, outlet 313 is arranged opposite to and connected to all third air outlets 1213. The first windbreak 321 blocks all first air outlets 1211 and all second air outlets 1212, so that the airflow is discharged upward from the third air outlet 1213. The third air outlet 1213 is an air outlet opening with a large air volume and high cooling efficiency.

[0154] Specifically, among the air outlets 121, the third air outlet 1213 corresponds to the highest air outlet direction. During the cooling process, the outlet 313 is positioned opposite to and connected to all the third air outlets 1213 located at the top, causing the cold air to be discharged upwards. The cold air then descends under the influence of gravity, which accelerates indoor air circulation and significantly improves the indoor cooling speed and temperature uniformity.

[0155] Of course, the air duct assembly 30 can also rotate in the opposite direction to the first direction F1, so that the airflow in the air duct 311 can flow out in any air outlet direction that can be achieved in this application.

[0156] In summary, as Figure 13 As shown, the indoor unit 100 of the air conditioner can realize heating mode, cooling mode, heating with weak airflow mode, cooling with weak airflow mode, no airflow mode, and standby mode. The air supply state of the indoor unit 100 is diverse, which can meet the special air supply needs of users, such as no airflow needs and weak airflow needs, which helps to improve user comfort and meet different user needs. In the no airflow mode and standby mode, the outlet 313 of the air duct 311 is opposite to and connected to the second air outlet 1212.
