[0054] 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.

[0055] Reference Figures 1-16 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.

[0056] Specifically, the housing 10 has an air inlet 111 and multiple air outlets 121 arranged in a first direction F1. External airflow enters the indoor unit 100 through the air inlet 111, and airflow within the indoor unit 100 flows to the outside through at least one air outlet 121. The first direction F1 can extend along a straight line, curve, or irregular shape, facilitating adjustment of the positions of the multiple air outlets 121. A chassis 20 is located inside the housing 10 and can be used to install components such as the duct assembly 30, indoor fan 40, and indoor heat exchanger 50.

[0057] The air duct assembly 30 is disposed on the chassis 20 and defines an air outlet duct 311, which is a channel for airflow. The air duct assembly 30 is movable relative to the chassis 20 so that the outlet 313 of the air duct 311 can selectively communicate with at least one of a plurality of air outlets 121. The inlet 312 of the air duct 311 communicates with the air inlet 111, and the outlet 313 of the air duct 311 can selectively communicate with at least one of a plurality of air outlets 121, so that the airflow flowing into the indoor unit 100 of the air conditioner through the air inlet 111 flows into the air duct 311 through the inlet 312 and flows to the air outlet 121 through the outlet 313 to flow to the outside.

[0058] Both the indoor fan 40 and the indoor heat exchanger 50 are mounted 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 airflow direction. The indoor fan 40 can be a cross-flow fan, 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.

[0059] The air duct assembly 30 is movable relative to the chassis 20; for example, the air duct assembly 30 is rotatable, movable, or both rotatable and movable on the chassis 20. 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.

[0060] 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 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.

[0061] 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.

[0062] 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 multiple air outlets 121, 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.

[0063] 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.

[0064] In some embodiments of this utility model, such as Figures 1-14 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.

[0065] In some embodiments, such as Figures 1-12As shown, the baffle 32 is connected to the side of the duct component 31 away from the indoor fan 40, and the outlet 313 of the duct 311 is formed on the baffle 32. When the duct component 30 is moved to a state where the outlet 313 of the duct 311 is opposite to and communicates with at least a portion of one of the air outlets 121, the baffle 32 blocks at least a portion of the other air outlet 121, causing airflow to exit from the air outlet 121 that is opposite to and communicates with the outlet 313.

[0066] By blocking the air outlet 121 that is not opposite to the outlet 313 with the baffle 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. This helps to increase the airflow volume 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 and meeting user needs.

[0067] In some embodiments, 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, and 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. Through the first wind deflector 321 and the second wind deflector 322 on both sides of the outlet 313 along the first direction F1, during the movement of the air duct assembly 30, the first wind deflector 321 can block the outlet 313 on one side along the first direction F1 (e.g., ...). 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 313 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, which is conducive to increasing the air volume at the corresponding air outlet 121.

[0068] 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 the outlet 313 to be set opposite to and connected to the corresponding air outlet 121 so that the airflow in the indoor unit 100 of the air conditioner flows to the outside through the corresponding air outlet 121.

[0069] 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 second air baffle 322 blocks at least a portion of the second air outlet 1212. For example Figures 4-5As shown, with the outlet 313 and a portion of the first air outlet 1211 positioned opposite each other and connected, the second windbreak 322 blocks a portion of the second air outlet 1212. For example... Figures 2-3 As shown, with the outlet 313 being disposed opposite to and connected to all the first air outlets 1211, the second windbreak 322 blocks all the second air outlets 1212.

[0070] 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 first windbreak 321 blocks at least a portion of the first air outlet 1211. For example Figures 4-5 As shown, when the outlet 313 is positioned opposite to and connected to a portion of the second air outlet 1212, the first windbreak 321 blocks a portion of the first air outlet 1211. For example... Figures 6-7 As shown, when the outlet 313 is disposed opposite to and connected to all the second air outlets 1212, the first windbreak 321 blocks all the first air outlets 1211.

[0071] 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 casing 10, allowing for more airflow directions within a limited space. This improves 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 airflow direction corresponding to all the first air outlets 1211, for example... Figures 4-5 As shown, the airflow can be directed 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 discharged forward and downward along the airflow direction corresponding to all the second air outlets 1212.

[0072] In addition, the dimensions of the first air outlet 1211 and the second air outlet 1212 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.

[0073] In some embodiments of this utility model, such as Figures 1-12As shown, the size of the first wind deflector 321 in the first direction F1 is greater than or equal to the size of the first air outlet 1211 in the first direction F1, and the size of the second wind deflector 322 in the first direction F1 is greater than or equal to the size of the second air outlet 1212 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 size of the second wind deflector 322 is large enough to completely block the second air outlet 1212. 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, thereby increasing the airflow volume in the direction corresponding to the outlet 121 opposite to the outlet 313. This improves the cooling or heating efficiency of the indoor unit 100 in the corresponding external space in that airflow direction, meeting user needs.

[0074] In some embodiments, such as Figures 1-12 As shown, the outlet 313, the first air outlet 1211, and the second air outlet 1212 of the air duct 311 have the same size 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, and 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.

[0075] With the outlet 313 of the air duct 311 directly opposite the first air outlet 1211 (i.e., opposite to all of the first air outlets 1211), the second baffle 322 blocks all of the second air outlets 1212, allowing the airflow within the air duct 311 to be completely discharged along the air outlet direction corresponding to the first air outlet 1211. With the outlet 313 of the air duct 311 directly opposite the second air outlet 1212 (i.e., opposite to all of the second air outlets 1212), the first baffle 321 blocks all of the first air outlets 1211, allowing the airflow within the air duct 311 to be completely discharged along the air outlet direction corresponding to the second air outlet 1212. This improves the airflow volume in the air outlet direction corresponding to the air outlet 121 opposite to the outlet 313, thereby increasing the cooling or heating efficiency of the indoor unit 100 for the corresponding external space and meeting user needs.

[0076] 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, and in the first direction F1, the second air outlet 1212 is located between the first air outlet 1211 and the third air outlet 1213.

[0077] 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 second air baffle 322 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 to each other, the second air baffle 322 blocks a portion of the second air outlet 1212 and all of the third air outlet 1213. For example Figures 2-3 As shown, with the outlet 313 being disposed opposite to and connected to all the first air outlets 1211, the second air baffle 322 blocks all the second air outlets 1212 and all the third air outlets 1213.

[0078] 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 first windbreak 321 blocks at least a portion of the first air outlet 1211, and the second windbreak 322 blocks at least a portion of the third air outlet 1213. For example Figures 4-5 As shown, in a state where outlet 313 is disposed opposite to and connected to a portion of the first air outlet 1211 and a portion of the second air outlet 1212, the first windbreak 321 blocks another portion of the first air outlet 1211, and the second windbreak 322 blocks another portion of the second air outlet 1212 and all of the third air outlet 1213. For example Figures 8-9 As shown, in the state where outlet 313 is disposed opposite to and connected to a portion of the second air outlet 1212 and a portion of the third air outlet 1213, the first windbreak 321 blocks all of the first air outlet 1211 and another portion of the second air outlet 1212, and the second windbreak 322 blocks another portion of the third air outlet 1213. For example Figures 6-7 As shown, when the outlet 313 is disposed opposite to and connected to 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 second air outlets 1212.

[0079] 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 first windbreak 321 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 first windbreak 321 blocks all of the first air outlet 1211 and a portion of the second air outlet 1212. For example... Figures 10-12 As shown, with the outlet 313 and all the third air outlets 1213 arranged opposite to each other and connected, the first windbreak 321 blocks all the first air outlets 1211 and all the second air outlets 1212.

[0080] The multiple 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 multiple air outlets 121 on the housing 10 and increase the number of possible air outlet directions.

[0081] 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 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.

[0082] In some embodiments, such as Figures 1-12 As shown, 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, and 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, thereby increasing the airflow volume in the air outlet direction corresponding to the outlet 121 opposite to the outlet 313. This improves the cooling or heating efficiency of the indoor unit 100 in the corresponding external space in that air outlet direction, meeting user needs.

[0083] 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.

[0084] With the outlet 313 of the air duct 311 directly opposite the first air outlet 1211, the second windbreak 322 blocks the second air outlet 1212 and all of the third air outlet 1213, allowing the airflow within the air duct 311 to exit completely along the air outlet direction corresponding to the first air outlet 1211. With the outlet 313 of the air duct 311 directly opposite the second air outlet 1212, the first windbreak 321 blocks all of the first air outlet 1211, and the second windbreak 322 blocks all of the third air outlet 1213, allowing the airflow within the air duct 311 to exit completely along the air outlet direction corresponding to the second air outlet 1212. With the outlet 313 of the air duct 311 facing the third air outlet 1213 (i.e., opposite to 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 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 and meeting user needs.

[0085] In some embodiments of this utility model, such as Figure 1 and Figures 13-15 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.

[0086] In some embodiments, such as Figure 1 and Figures 13-15 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 10, and the other is located on the air duct assembly 30. For example... Figure 1 and Figures 13-15 As shown, gear 621 and drive motor 61 are mounted together on chassis 20, and rack 622 is mounted on air duct assembly 30.

[0087] 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.

[0088] 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 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, so that the air duct assembly 30 moves 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] In some embodiments of this utility model, such as Figures 1-14 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.

[0094] 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.

[0095] 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.

[0096] In some embodiments, such as Figures 13-15As 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.

[0097] In some embodiments of this utility model, such as Figures 1-12 As shown, at least one of the first air outlet 1211, the second air outlet 1212, and the third air outlet 1213 is an air outlet opening, and the shape of the 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 air outlet opening to flow directly to the outside, which helps to increase the air volume at the air outlet opening and improve the cooling or heating efficiency of the indoor unit 100 of the air conditioner.

[0098] In some embodiments, such as Figures 1-12 As shown, at least one of the first air outlet 1211, the second air outlet 1212, and the third air outlet 1213 is a diffuser. The diffuser has the same shape as the outlet 313 of the air duct 311, and the diffuser is provided with multiple spaced-apart air diffusers. When the indoor unit 100 of the air conditioner is turned on, the large airflow from the outlet 313 to the diffusers can be divided into multiple smaller airflows by the multiple diffusers, which helps to achieve windless airflow and improves user comfort.

[0099] 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 helps to protect the indoor unit 100 of the air conditioner.

[0100] In some embodiments of this utility model, such as Figure 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 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] like Figures 1-16 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, an indoor heat exchanger 50, a drive assembly 60, and a louver assembly 70.

[0105] 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.

[0106] The face frame 11 has an air inlet 111, and the air outlet panel 12 has multiple air outlets 121 arranged in the first direction F1. The multiple air outlets 121 have different air outlet directions, and the air outlet panel 12 is an arc-shaped plate, so that the first direction F1 is the extension direction of an arc.

[0107] The length of the air outlet panel 12 extends in the left-right direction. The first direction F1 can be a direction that gradually extends upwards from back to front, or a direction that gradually extends downwards from front to back. In this specific embodiment, as... Figures 1-12 As shown, the first direction F1 is taken as the direction that gradually extends upwards from back to front.

[0108] 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 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 is an air outlet opening, the second air outlet 1212 is an air diffuser with a plurality of spaced-apart air diffusers, and the third air outlet 1213 is an air outlet opening.

[0109] The chassis 20 is housed within the casing 10, and the air duct assembly 30 is rotatably mounted on the chassis 20. The center of the arc containing the first direction F1 is located on the rotation axis of the air duct assembly 30. The air duct assembly 30 includes an air duct component 31 and a baffle plate 32. The air duct component 31 defines an air duct 311. The inlet 312 of the air duct 311 communicates with the air inlet 111, and the air duct assembly 30 is rotatable relative to the chassis 20 so that the outlet 313 of the air duct 311 can selectively communicate with at least one of a plurality of air outlets 121.

[0110] 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. The rotation axis of the air duct assembly 30 coincides with the rotation axis of the indoor fan 40.

[0111] 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 first 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.

[0112] The wind deflector 32 is an arc-shaped plate corresponding to the shape of the air outlet panel 12. In the first direction F1, the size of the first wind deflector 321 is equal to the sum of the sizes of the first air outlet 1211 and the second air outlet 1212, and the size of the second wind deflector 322 is equal to the sum of the sizes of the second air outlet 1212 and the third air outlet 1213. The sizes of the outlet 313 of the air duct 311, the first air outlet 1211, the second air outlet 1212, and the third air outlet 1213 are equal.

[0113] When the air duct assembly 30 is rotated to a state where the outlet 313 of the air duct 311 is positioned opposite to and connected to at least a portion of one of the air outlets 121, the baffle 32 blocks the portion of the plurality of air outlets 121 that is not opposite to the outlet 313.

[0114] During the rotation 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 weak wind sensation modes with different air outlet directions and different air outlet volumes.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] During the operation of the indoor unit 100, the outside airflow enters the indoor unit 100 through the air inlet 111, flows through the indoor heat exchanger 50 for heat exchange, and then flows to the air duct 311 through the indoor fan 40. The heat-exchanged airflow enters the air duct 311 through the inlet 312 and flows to the outside through the outlet 313 of the air duct 311 from the corresponding air outlet 121.

[0119] 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.

[0120] First, such as Figures 2-3 As shown, with the outlet 313 and all the first air outlets 1211 being opposite to and connected, the second baffle 322 blocks all the second air outlets 1212 and all the third air outlets 1213, causing the airflow to exit downwards from the first air outlet 1211. The first air outlet 1211 is an air outlet opening with a large air volume and high cooling or heating efficiency.

[0121] Specifically, among the air outlets 121, the first air outlet 1211 corresponds to the lowest air outlet direction. In heating mode, the outlet 313 is positioned opposite to and connected to all the first air outlets 1211 located at the lowest side, causing the airflow to exit downwards. The air outlet direction is 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 the indoor temperature.

[0122] Then, the air duct assembly 30 rotates along the first direction F1, as follows: Figures 4-5 As shown, with outlet 313 positioned opposite 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 the remaining parts of the first air outlet 1211, and the second baffle 322 blocks the remaining 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 gentle breeze. Specifically, in heating mode, the airflow is generally downward, and the hot air rises under gravity, which not only increases the rate of indoor temperature rise but also achieves a gentle breeze during heating, improving user comfort.

[0123] The air duct assembly 30 continues to rotate in the first direction F1, as... Figures 6-7 As shown, with outlet 313 and all second air outlets 1212 opposite to and connected, the first baffle 321 blocks all first air outlets 1211, and the 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.

[0124] The air duct assembly 30 continues to rotate in the first direction F1, as... Figures 8-9As shown, with the outlet 313 and the upper part of the second air outlet 1212 and the lower part of the third air outlet 1213 respectively, and in a state where the 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 the 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.

[0125] Specifically, among the air outlets 121, the air outlet direction corresponding to the third air outlet 1213 is the highest, i.e. 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. In cooling mode, outlet 313 is positioned opposite to and connected to the upper part of the second air outlet 1212 and the uppermost part of the third air outlet 1211, so that the airflow is directed upward and the cold air descends under the action of gravity. This not only improves the indoor cooling speed, but also achieves a weak cooling breeze, improving the user's comfort.

[0126] The air duct assembly 30 continues to rotate in the first direction F1, as... Figures 10-12 As shown, with outlet 313 positioned opposite and connected to all third air outlets 1213, the first baffle 321 blocks all first air outlets 1211 and all second air outlets 1212, allowing airflow to flow directly from the third air outlets 1213 to the outside. Specifically, in cooling mode, outlet 313 is positioned opposite and connected to all the uppermost third air outlets 1213. 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, causing the airflow to rise, while 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.

[0127] Of course, the air duct assembly 30 can also rotate in the opposite direction to the first direction F1 in this specific embodiment, so that the airflow in the air duct 311 can flow out in any desired air outlet direction that can be achieved in this application.

[0128] In summary, as Figure 16As shown, the indoor unit 100 of the air conditioner can realize six working modes: heating mode, cooling mode, heating with weak airflow mode, cooling with weak airflow mode, no airflow mode, and standby mode.
