[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 10, a chassis 20, an air duct assembly 30, an indoor fan 40, and an indoor heat exchanger 50.

[0057] Specifically, the housing 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. A chassis 20 is housed within the housing 10 and can be used to mount components such as the duct assembly 30, the indoor fan 40, and the indoor heat exchanger 50. The duct assembly 30 is movably mounted on the chassis 20; for example, the duct assembly 30 can be rotatable, movable, or both rotatable and movable on the chassis 20.

[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, 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 located on the chassis 20. The indoor fan 40 is located at the inlet 312 of the air duct 311, and the indoor heat exchanger 50 is located between the indoor fan 40 and the air inlet 111 in the direction of air flow. The indoor fan 40 can be a cross-flow fan that 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 casing 10 includes an air outlet panel 12, with multiple air outlets 121 disposed on the air outlet panel 12 and having different air outlet directions. During the movement of the air duct assembly 30 relative to the chassis 20, 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 multiple 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 airflow can be achieved through multiple air outlets 121, which helps meet user needs.

[0062] 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.

[0063] This application achieves multi-directional airflow by allowing the air duct assembly 30 to move relative to the chassis 20, 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 air outlet panel 12, 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.

[0064] According to the embodiment of the present utility model, the air conditioner indoor unit 100 can directly change the position of the outlet 313 of the air duct 311 to change the airflow direction by movably mounting the air duct assembly 30 on the chassis 20, thereby realizing multi-directional air outlet of the air conditioner indoor unit 100, with a large air outlet range and low air outlet noise, resulting in a better user experience.

[0065] In some embodiments of this utility model, such as Figures 1-12 As shown, the air outlet panel 12 is an arc-shaped plate, and multiple air outlets 121 are arranged along the arc-shaped extension direction F1 of the air outlet panel 12, so that the air outlets 121 have different air outlet directions. The multiple air outlets 121 are arranged along the arc-shaped extension direction F1, which makes the connection between adjacent air outlets 121 smoother. As the outlet 313 moves from connecting with one air outlet 121 to connecting with another adjacent air outlet 121 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 air outlet direction, and the effect of multi-directional air outlet is better achieved.

[0066] In some embodiments, such as Figures 12-13 As 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.

[0067] 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°.

[0068] In some embodiments, such as Figures 1-12 As shown, the air duct assembly 30 is rotatably mounted on the chassis 20, and 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. During the rotation of the air duct assembly 30, the outlet 313 can move along the arrangement direction of the multiple air outlets 121, i.e., the arc-shaped extension 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 the corresponding air outlet direction of the air outlet 121.

[0069] In this application, the corresponding air outlet 121 refers to the air outlet 121 that needs to be set opposite to and connected to the outlet 313, for example, the user can adjust it so that the outlet 313 is set opposite to and connected to the corresponding air outlet 121.

[0070] In some embodiments, 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.

[0071] 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 an arcuate extension direction F1. One of the gear 621 and the rack 622 is located on the chassis 20 or the housing 10, and the other is located on the air duct assembly 30. For example Figure 1 and Figures 14-16As shown, gear 621 and drive motor 61 are mounted together on chassis 20, and rack 622 is mounted on air duct assembly 30.

[0072] Gear 621 rotates under the drive of drive motor 61, causing rack 622 to move along the arc-shaped extension direction F1, thus enabling air duct assembly 30 to move relative to chassis 20. Through the meshing transmission of gear 621 and rack 622, the driving force of drive motor 61 is transmitted to air duct assembly 30, achieving high transmission accuracy. This improves the movement accuracy of air duct assembly 30, allowing it to move precisely until the outlet 313 of air duct 311 connects with the corresponding air outlet 121, thus meeting the user's needs for airflow from different directions.

[0073] In some embodiments of this utility model, such as Figures 1-12 As shown, the length of the air outlet panel 12 extends in the left-right direction, and the arc-shaped extension direction F1 of the air outlet panel 12 gradually extends upward from back to front. Multiple air outlets 121 are arranged from back to front and gradually upward, and the outlet 313 is at least partially connected to at least one of the multiple air outlets 121, enabling the indoor unit 100 to discharge air downwards, forwards, or both downwards and forwards, thereby achieving the cooling or heating function of the indoor unit 100 for the space below and in front of itself, meeting the user's needs.

[0074] 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 arcuate extension direction F1 of the air outlet panel 12, causing the outlet 313 of the air duct 311 to rotate forward and upward, thus transforming the air conditioner indoor unit 100 into... Figures 4-5 The state shown.

[0075] In some embodiments, such as Figures 1-12 As shown, the housing 10 also includes a face frame 11 and a front panel 13, with the front panel 13 covering the upper front side of the face frame 11. The air outlet panel 12 covers the bottom and lower front side of the face frame 11, and the lower end of the front panel 13 is connected to the air outlet panel 12 by an arc. This allows the front panel 13 to have a different shape from the air outlet panel 12, providing a larger installation space inside the air conditioner indoor unit 100 at the front panel 13 for installing 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.

[0076] 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.

[0077] In some embodiments, such as Figure 1 As shown, the air outlet panel 12 is detachably mounted on the front frame 11, making the housing 10 easier to manufacture.

[0078] 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.

[0079] In some embodiments, such as Figures 1-12 and 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.

[0080] In some embodiments, such as Figures 1-12 As shown, the air duct assembly 30 also includes a baffle plate 32, which 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. When the air duct assembly 30 is in a state where the outlet 313 of the air duct 311 is opposite to and communicates with at least a portion of one of the air outlets 121, the baffle plate 32 blocks at least a portion of the other air outlet 121, causing airflow to exit from the air outlet 121 opposite to and communicating with the outlet 313.

[0081] 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. By blocking the air outlet 121 that is not opposite to the outlet 313 by the baffle plate 32, more airflow in the air duct 311 can flow out from the air outlet 121 opposite to the outlet 313, reducing the possibility of airflow escaping in other directions, which is conducive to increasing the airflow in the air outlet direction corresponding to the air outlet 121 opposite to the outlet 313, thereby improving the cooling or heating efficiency of the indoor unit 100 of the air conditioner in the corresponding external space of the air outlet direction.

[0082] In some embodiments, such as Figures 1-15As 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 F1. 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 F1. 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.

[0083] In some embodiments, such as Figures 1-12 As shown, the dimension of the air outlet panel 12 in the arc-shaped extension direction F1 is larger than the dimension of the baffle 32 in the arc-shaped extension direction F1, and the central angle e corresponding to the air outlet panel 12 is less than 180°. In the arc-shaped extension direction F1, 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.

[0084] In some embodiments, such as Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figures 11-12 As shown, the side of the housing 10 facing the baffle 32 has a groove 122 extending along the arcuate extension direction F1, 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.

[0085] 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.

[0086] For example, in some embodiments, such as Figure 3 , Figure 5 , Figure 7 , Figure 9 and Figures 11-12As shown, the two ends of the chute 122 along the arcuate extension 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 along the arcuate extension direction F1 is positioned opposite 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 along the arcuate extension direction F1 is positioned opposite the outlet 313 of the air duct 311, and the baffle plate 32 blocks the remaining air outlets 121.

[0087] The first closed end 1221 and the second closed end 1222 can limit the wind baffle 32, so that the air duct assembly 30 stops moving when the outlet 313 is opposite to and connected to the air outlets 121 at both ends of the arc-shaped extension direction F1. This improves the control accuracy of the movement stroke 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 arc-shaped extension direction F1.

[0088] For example, in some specific embodiments, such as Figure 3 As shown, with the baffle 32 abutting against the first closed end 1221 located on the lower side, the lowermost air outlet 121 is opposite to and connected to the outlet 313 of the air duct 311, and the baffle 32 blocks other air outlets 121. Figures 11-12 As shown, with the baffle plate 32 abutting against the second closed end 1222 located on the upper side, the uppermost air outlet 121 is opposite to and connected to the outlet 313 of the air duct 311, and the baffle plate 32 blocks other air outlets 121.

[0089] In some embodiments of this utility model, such as Figures 1-12 As shown, the plurality of air outlets 121 include at least a first air outlet 1211 and a second air outlet 1212, with the second air outlet 1212 located in front of and above the first air outlet 1211.

[0090] When the air duct assembly 30 is in a state where the outlet 313 of the air duct 311 is opposite to and connected to at least a portion of the first air outlet 1211, the baffle 32 blocks at least a portion of the second air outlet 1212. For example Figures 4-5 As shown, with outlet 313 and a portion of the first air outlet 1211 opposite to and connected, the baffle 32 blocks the second air outlet 1212 and another portion of the first air outlet 1211; as Figures 2-3 As shown, with the outlet 313 and the first air outlet 1211 being arranged opposite to each other and connected, the baffle 32 blocks the entire second air outlet 1212.

[0091] When the air duct assembly 30 is in a state where the outlet 313 of the air duct 311 is opposite to and connected to at least a portion of the second air outlet 1212, the baffle 32 blocks at least a portion of the first air outlet 1211. For example Figures 4-5 As shown, with outlet 313 and a portion of the second air outlet 1212 arranged opposite to and connected, the baffle 32 blocks the first air outlet 1211 and another portion of the second air outlet 1212; as Figures 6-7 As shown, with the outlet 313 and the second air outlet 1212 being arranged opposite to each other and connected, the baffle 32 blocks the entire first air outlet 1211.

[0092] The multiple air outlets 121 include at least a first air outlet 1211 and a second air outlet 1212. The relatively small number of air outlets 121 reduces the space occupied by the multiple air outlets 121 on the air outlet panel 12, allowing for more air outlet directions to be achieved within a limited space. This facilitates improving the structural compactness of the air conditioning indoor unit 100 while achieving multi-directional airflow. For example... Figures 2-3 As shown, the airflow can be directed forward and downward along the overall airflow direction corresponding to the first air outlet 1211, for example... Figures 4-5 As shown, the airflow can be discharged forward and downward 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 directed forward and downward along the multiple air outlet directions corresponding to the second air outlet 1212.

[0093] In addition, the dimensions of the first air outlet 1211 and the second air outlet 1212 along the arc-shaped extension direction F1 can be flexibly adjusted according to the air outlet requirements, so as to flexibly adjust the air outlet direction of the air conditioner indoor unit 100.

[0094] In some embodiments, such as Figures 1-15 As shown, the wind deflector 32 includes a first wind deflector 321 and a second wind deflector 322. In the arcuate extension 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 above and in front of the first wind deflector 321. Through the first wind deflector 321 and the second wind deflector 322 on both sides of the outlet 313 along the arcuate extension direction F1, during the movement of the air duct assembly 30, the first wind deflector 321 can block the air outlet 121 on the lower side of the outlet 313 along the arcuate extension direction F1, and the second wind deflector 322 can block the air outlet 121 on the upper side of the outlet 313 along the arcuate extension direction F1. This achieves zoned blocking of multiple air outlets 121 along the arrangement direction of the multiple air outlets 121, i.e., the arcuate extension direction F1, which helps to increase the airflow at the corresponding air outlet 121.

[0095] In some embodiments, such as Figures 1-12As shown, the first air outlet 1211 is the first air outlet opening, and the shape of the first air outlet opening is the same as the shape of the outlet 313 of the air duct 311. This allows the airflow from the outlet 313 to the first air outlet opening to flow directly to the outside. The first air outlet opening does not easily obstruct the airflow, which helps to increase the air volume at the first air outlet opening and improve the cooling or heating efficiency of the indoor unit 100 of the air conditioner.

[0096] In some embodiments, the first air outlet 1211 is a first air diffuser, which has the same shape as the outlet 313 of the air duct 311. The first air diffuser is provided with a plurality of spaced-apart first air diffuser holes. When the indoor unit 100 of the air conditioner is turned on, the large airflow from the outlet 313 to the first air diffuser holes can be divided into multiple smaller airflows by the multiple first air diffuser holes, so as to disperse the concentrated airflow into many fine air filaments, making the air outlet more uniform, which is conducive to achieving windless air outlet and making the user feel more comfortable.

[0097] When the indoor unit 100 is in standby mode, the first air diffuser can cover the outlet 313 of the air duct 311, reducing 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 protecting the indoor unit 100.

[0098] In some embodiments, the second air outlet 1212 is a second air outlet opening, and the shape of the second air outlet opening is the same as the shape of the outlet 313 of the air duct 311, so that the airflow from the outlet 313 to the second air outlet opening can flow directly to the outside, which is beneficial to increase the air volume at the second air outlet opening and improve the cooling or heating efficiency of the air conditioning indoor unit 100.

[0099] In some embodiments, such as Figures 1-12 As shown, the second air outlet 1212 is a second air diffuser, which has the same shape as the outlet 313 of the air duct 311. The second air diffuser has multiple spaced-apart second air diffuser holes. When the indoor unit 100 of the air conditioner is turned on, the large airflow from the outlet 313 to the second air diffuser holes can be divided into multiple smaller airflows by the multiple second air diffuser holes, which helps to achieve windless airflow and improve the user's comfort.

[0100] 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 second air diffuser, which helps to protect the indoor unit 100 of the air conditioner.

[0101] For example, in some specific embodiments, such as Figures 1-12 As shown, the first air outlet 1211 is the first air outlet opening, and the second air outlet 1212 is the second air diffuser. Figures 2-3As shown, with outlet 313 and the first air outlet facing each other, the baffle 32 blocks the second air diffuser, enabling rapid cooling or heating at the first air outlet. Figures 6-7 As shown, with the outlet 313 and the second air diffuser plate facing each other, the second air diffuser plate blocks the outlet 313. This allows for windless cooling or heating at the outlet 313 when the indoor unit 100 is running, and also protects the indoor unit 100 by covering the outlet 313 when it is in standby mode. Figures 4-5 As shown, when outlet 313 is opposite to a portion of the first air outlet and a portion of the second air diffuser, part of the airflow from outlet 313 flows out quickly from the first air outlet, and the other part flows out from the second air diffuser and is decomposed into multiple small airflows, which helps to achieve a weak cooling or heating effect and improves user comfort.

[0102] In some embodiments of this utility model, such as Figures 1-12 As shown, the plurality of air outlets 121 also include at least a third air outlet 1213. In the arcuate extension 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.

[0103] When the air duct assembly 30 is in a state where the outlet 313 of the air duct 311 is opposite to and connected to at least a portion of the first air outlet 1211, the baffle 32 blocks at least a portion of the second air outlet 1212 and at least a portion of the third air outlet 1213. For example Figures 4-5 As shown, with outlet 313 and a portion of the first air outlet 1211 arranged opposite to and connected, the baffle 32 blocks the second air outlet 1212, the third air outlet 1213, and another portion of the first air outlet 1211; as Figures 2-3 As shown, with the outlet 313 and the first air outlet 1211 being arranged opposite to each other and connected, the baffle 32 blocks the entire second air outlet 1212 and the entire third air outlet 1213.

[0104] When the air duct assembly 30 is in a state where the outlet 313 of the air duct 311 is opposite to and connected to at least a portion of the second air outlet 1212, the baffle 32 blocks at least a portion of the first air outlet 1211 and at least a portion of the third air outlet 1213. For example Figures 4-5 and Figures 8-9 As shown, with outlet 313 and a portion of the second air outlet 1212 arranged opposite to and connected, the baffle 32 blocks the first air outlet 1211, the third air outlet 1213, and another portion of the second air outlet 1212; as Figures 6-7As shown, with the outlet 313 and the second air outlet 1212 being arranged opposite to each other and connected, the baffle 32 blocks the entire first air outlet 1211 and the entire third air outlet 1213.

[0105] When the air duct assembly 30 is in a state where the outlet 313 of the air duct 311 is opposite to and connected to at least a portion of the third air outlet 1213, the baffle 32 blocks at least a portion of the first air outlet 1211 and at least a portion of the second air outlet 1212. For example Figures 8-9 As shown, with outlet 313 and a portion of the third air outlet 1213 arranged opposite to and connected to each other, the baffle 32 blocks the first air outlet 1211, the second air outlet 1212, and another portion of the third air outlet 1213; as Figures 10-12 As shown, with the outlet 313 and the third air outlet 1213 being arranged opposite to each other and connected, the baffle 32 blocks the entire first air outlet 1211 and the entire second air outlet 1212.

[0106] The plurality of air outlets 121 include at least a first air outlet 1211, a second air outlet 1212 and a third air outlet 1213. The number of air outlets 121 is small, which can reduce the space occupied by the plurality of air outlets 121 on the air outlet panel 12 and increase the number of possible air outlet directions.

[0107] In addition, the dimensions of the first air outlet 1211, the second air outlet 1212 and the third air outlet 1213 along the arc-shaped extension direction F1 can be adjusted according to the air outlet requirements, so as to flexibly adjust the air outlet direction of the air conditioner indoor unit 100.

[0108] In some embodiments, such as Figures 1-12 As shown, the third air outlet 1213 is the third air outlet opening, and the shape of the third air outlet opening is the same as the shape of the outlet 313 of the air duct 311. This allows the airflow from the outlet 313 to the third air outlet opening to flow directly to the outside, which helps to increase the air volume at the third air outlet opening and improve the cooling or heating efficiency of the indoor unit 100 of the air conditioner.

[0109] In some embodiments, the third air outlet 1213 is a third air diffuser, which has the same shape as the outlet 313 of the air duct 311, and is provided with a plurality of spaced-apart third air diffusers. When the indoor unit 100 of the air conditioner is turned on, the large airflow from the outlet 313 to the third air diffusers can be divided into multiple smaller airflows by the multiple third air diffusers, which helps to achieve windless airflow and improve user comfort.

[0110] 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 third air diffuser, which helps to protect the indoor unit 100 of the air conditioner.

[0111] In some embodiments, such asFigure 1 and Figure 12 As shown, the indoor unit 100 of the air conditioner also includes a sway vane assembly 70, which is disposed in the air duct assembly 30 and moves together with the air duct assembly 30. The sway vane assembly 70 includes multiple sway vanes 71, which are oscillatingly disposed within the air duct 311. By oscillating the sway vanes 71 relative to the air duct 311, and by allowing the sway vanes 71 to move together with the air duct assembly 30, the range of airflow direction can be further increased to meet the user's demand for airflow from the indoor unit 100 in more directions.

[0112] 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.

[0113] The air conditioner according to an embodiment of the present invention includes an indoor unit 100. 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 mounting the duct assembly 30 on the chassis 20, can directly change the position of the outlet 313 of the duct 311 to change the airflow direction, thereby achieving multi-directional airflow from the indoor unit 100, resulting in a large airflow range, low noise, and a better user experience.

[0114] 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.

[0115] 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 10, a chassis 20, an air duct assembly 30, an indoor fan 40, and an indoor heat exchanger 50.

[0116] The housing 10 includes a front frame 11, an air outlet panel 12, and a front panel 13. The front panel 13 covers the upper front side of the front frame 11, and the air outlet panel 12 covers the bottom and lower front side of the front 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.

[0117] The housing 10 has an air inlet 111 and multiple air outlets 121, which are located on the air outlet panel 12 and have different air outlet directions. The air outlet panel 12 is an arc-shaped panel, and the multiple air outlets 121 are arranged along the arc-shaped extension direction F1 of the air outlet panel 12 so that the air outlets 121 have different air outlet directions. The length direction of the air outlet panel 12 extends in the left-right direction, and the arc-shaped extension direction F1 of the air outlet panel 12 extends gradually upward from back to front.

[0118] The plurality of air outlets 121 include a first air outlet 1211, a second air outlet 1212, and a third air outlet 1213. In the arcuate extension 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 is a first air outlet opening, the second air outlet 1212 is a second air diffuser plate, the second air diffuser plate is provided with a plurality of spaced-apart second air diffuser holes, and the third air outlet 1213 is a third air outlet opening.

[0119] The chassis 20 is disposed within the housing 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.

[0120] 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.

[0121] The wind deflector 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 wind deflector 32. The wind deflector 32 includes a first wind deflector portion 321 and a second wind deflector portion 322. In the arcuate extension direction F1, the outlet 313 of the air duct 311 is located between the first wind deflector portion 321 and the second wind deflector portion 322, and the second wind deflector portion 322 is located in front of and above the first wind deflector portion 321.

[0122] 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.

[0123] The central axis of the cylindrical surface where the air outlet panel 12 is located, the central axis of the cylindrical surface where the baffle plate 32 is located, and the rotation axis of the air duct assembly 30 coincide.

[0124] In the arc-shaped extension direction F1, the size of the air outlet panel 12 is larger than the size of the baffle 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 on the air outlet panel 12 is b, the central angle corresponding to the area occupied by the second diffuser on the air outlet panel 12 is c, and the central angle corresponding to the area occupied by the third air outlet on the air outlet panel 12 is d, where b = c = d = a / 3. The sizes of the first air outlet, the second diffuser, the third air outlet, and the outlet 313 of the air duct 311 are equal. During the movement of the air duct assembly 30, the relative proportions of the first air outlet, the second diffuser, and the third air outlet to the outlet 313 can be adjusted to achieve weak wind sensation modes with different air outlet directions and different air volume.

[0125] During the operation of the indoor unit 100 of the air conditioner, the outside airflow enters the interior of the indoor unit 100 from the air inlet 111 and then flows through the indoor heat exchanger 50 and the indoor fan 40 for heat exchange. The airflow after heat exchange flows into the air duct 311 through the inlet 312 and flows to the outside from the corresponding air outlet 121 through the outlet 313 of the air duct 311.

[0126] The relative positions of the outlet 313 and the multiple air outlets 121 during the rotation of the air duct assembly 30 are described below.

[0127] First, such as Figures 2-3 As shown, with outlet 313 and the first air outlet being positioned opposite each other and connected, the second baffle 32 blocks the second diffuser and the third air outlet, causing airflow to exit downwards from the first air outlet. This results in a large air volume and high cooling or heating efficiency. Specifically, in heating mode, outlet 313 is positioned opposite to and connected to the lowermost first air outlet, causing airflow to exit downwards. Among the multiple air outlets 121 corresponding to different airflow directions... Figures 2-3 In the indicated state, the airflow direction is lowest and closer to the wall, which helps to generate a stronger Coanda effect, making the hot air stream more convergent and increasing the air volume. The hot air has better ground penetration and rolls a longer distance along the ground. Since hot air is lighter than cold air, the hot air flowing to the outside will rise under the action of gravity, increasing the temperature rise rate of the foot warmer and the room, and significantly improving the uniformity of indoor temperature.

[0128] Then, the air duct assembly 30 rotates along the arc-shaped extension direction F1, as follows: Figures 4-5As shown, with the outlet 313 positioned opposite and connected to the upper part of the first air outlet and the lower part of the second diffuser, the first baffle 32 blocks the rest of the first air outlet, and the second baffle 32 blocks the rest of the second diffuser and the entire third air outlet. This causes part of the airflow from the outlet 313 to flow directly out through the first air outlet, while the other part is dispersed by the second diffuser before flowing out. This reduces the airflow velocity and intensity to a certain extent, achieving a gentle breeze. In particular, in heating mode, the airflow is generally downward, and the hot air rises under gravity. This not only increases the rate of indoor temperature rise but also achieves a gentle breeze during heating, improving user comfort.

[0129] The air duct assembly 30 continues to rotate along the arc-shaped extension direction F1, as... Figures 6-7 As shown, with the outlet 313 and the second diffuser plate positioned opposite each other and connected, the first baffle plate 32 completely blocks the first air outlet opening, and the second baffle plate 32 completely blocks the third air outlet opening. When the indoor unit 100 is on, the second diffuser plate disperses the airflow from the 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 diffuser plate covers the outlet 313 to protect the indoor unit 100.

[0130] The air duct assembly 30 continues to rotate along the arc-shaped extension direction F1, as... Figures 8-9 As shown, with outlet 313 positioned opposite and connected to the upper part of the second diffuser and the lower part of the third air outlet, the first baffle 32 blocks the entire first air outlet and the rest of the second diffuser, while the second baffle 32 blocks the rest of the third air outlet. This causes part of the airflow from outlet 313 to flow directly out through the third air outlet, while the other part is dispersed by the second diffuser before flowing out. This reduces the airflow velocity and intensity to a certain extent, achieving a weak draft. Specifically, in cooling mode... Figures 8-9 The airflow direction in the state shown is compared to Figures 2-3 The state shown Figures 4-5 The state shown Figures 6-7 The state shown is higher up, and the cold air descends under the influence of gravity, which not only improves the indoor cooling speed, but also achieves a weak cooling breeze, improving the user's comfort.

[0131] The air duct assembly 30 continues to rotate along the arc-shaped extension direction F1, as... Figures 10-12As shown, with outlet 313 and the third air outlet facing each other and connected, the first baffle 32 blocks the entire first air outlet and the entire second diffuser, allowing airflow to flow directly from the third air outlet to the outside. Specifically, in cooling mode, outlet 313 and the uppermost third air outlet are positioned opposite each other and connected. Figures 10-12 The airflow direction in the state shown is compared to Figures 8-9 The state shown is higher up, that is, among the multiple air outlets 121 corresponding to the air outlet directions. Figures 10-12 In the state shown, the airflow direction is at its highest, and the cold air descends under the influence of gravity, which can accelerate indoor air circulation and significantly improve the indoor cooling speed and temperature uniformity.

[0132] Of course, the air duct assembly 30 can also rotate in the opposite direction to the arcuate extension direction F1, so that the airflow at the outlet 313 can flow out in any desired airflow direction that can be achieved by this application.

[0133] In summary, as Figure 17 As shown, the indoor unit 100 of the air conditioner can realize six operating modes: heating mode, cooling mode, heating with weak airflow mode, cooling with weak airflow mode, no airflow mode, and standby mode. The diverse airflow patterns can meet users' special airflow needs, such as no airflow or weak airflow, thereby improving user comfort and satisfying different usage requirements. In the no airflow mode and standby mode, the outlet 313 of the air duct 311 is positioned opposite to and connected to the second diffuser.
