Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0070] In the description of this utility model, "first feature" and "second feature" may include one or more of the features, "multiple" means two or more, "first feature above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them, and "first feature above", "above" and "over" the second feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0071] The following description, with reference to the accompanying drawings, describes an air outlet device 10 and an indoor air conditioning unit 100 having the air outlet device 10 according to an embodiment of the present invention. The indoor air conditioning unit 100 may be a wall-mounted indoor air conditioning unit.

[0072] Reference Figures 1-27 As shown, the air outlet device 10 according to the embodiment of the present utility model may include an air outlet panel 11, a diffuser plate 12 and a first drive motor 13.

[0073] Specifically, the air outlet panel 11 has an air outlet 112, such as Figures 1-3 As shown, the airflow inside the indoor unit 100 of the air conditioner can flow outward through the air outlet 112. The diffuser 12 is slidably disposed on the inner side of the air outlet panel 11 along the first direction F1. The diffuser 12 slides to open or block the air outlet 112. The diffuser 12 has a plurality of spaced-apart air outlet holes.

[0074] like Figure 4 As shown, when the indoor unit 100 of the air conditioner is turned on, the diffuser plate 12 blocks the air outlet 112, so that the large airflow flowing out from the air outlet 112 can be divided into multiple small airflows by multiple diffuser holes, so as to disperse the concentrated large airflow into many fine air filaments, making the airflow more uniform, which is conducive to achieving windless airflow and making the user feel more comfortable.

[0075] like Figure 4As shown, when the indoor unit 100 of the air conditioner is in standby mode, the diffuser 12 blocks the air outlet 112. By covering the air outlet 112 with the diffuser 12, the risk of external dust or small stones and other impurities entering the indoor unit 100 and damaging the internal structure of the indoor unit 100 is reduced, which helps to protect the indoor unit 100.

[0076] like Figure 3 As shown, when the indoor unit 100 of the air conditioner is turned on, the diffuser 12 opens the air outlet 112, allowing the airflow from the air outlet 112 to flow directly to the outside. The air outlet 112 does not obstruct the airflow, which helps to increase the air volume and wind speed at the air outlet 112, thereby improving the heating or cooling efficiency of the indoor unit 100 of the air conditioner.

[0077] The first direction F1 can extend along a straight line, curve or irregular shape, which makes it easy to adjust the sliding direction of the diffuser plate 12 to control the area of ​​the air outlet 112 that is blocked or opened by the diffuser plate 12, which is conducive to achieving windless air outlet in a specific area.

[0078] During the sliding of the diffuser plate 12 along the first direction F1, the diffuser plate 12 is always located inside the air outlet panel 11. This not only reduces the interference of external impurities on the sliding of the diffuser plate 12 inside the air outlet panel 11, but also makes it difficult for users to see the part of the diffuser plate 12 located inside the air outlet panel 11 that does not correspond to the air outlet 112, thus achieving the effect of concealing unsightly parts and improving the user experience.

[0079] The diffuser 12 is slidable relative to the air outlet panel 11. Compared to other modes of movement such as rotation, the process of the diffuser 12 sliding to open or block the air outlet 112 is smoother and the air outlet effect is better.

[0080] The first drive motor 13 is connected to the air diffuser plate 12 via the first transmission mechanism 14. The first drive motor 13 drives the air diffuser plate 12 to slide along the first direction F1. The first drive motor 13 can be a stepper motor, AC motor, DC motor, or other types of motor. The first transmission mechanism 14 can be a gear and rack assembly, a slide rail and slider assembly, a ball screw, etc. The first transmission mechanism 14 transmits the driving force of the first drive motor 13 to the air diffuser plate 12 to drive the air diffuser plate 12 to slide. This allows for flexible adjustment of the relative positions of the first drive motor 13 and the air diffuser plate 12, making their placement more flexible to accommodate the installation positions of other structures within the air conditioner indoor unit 100 and improving the structural compactness of the components within the air conditioner indoor unit 100.

[0081] In some related technologies, the air deflector of the indoor unit of an air conditioner rotates to open or close the air outlet, allowing airflow inside the indoor unit to flow to the outside when the air outlet is open. However, when the air outlet is open, the airflow is direct and can easily cause headaches, dizziness, or general discomfort for users, thus endangering their health.

[0082] In this application, the air can be vented outward with the air diffuser 12 completely blocking the air outlet 112, so as to achieve windless airflow throughout the air outlet 112, which is conducive to improving the user's comfort. When the user uses the indoor unit 100 of the air conditioner in this state, the user is less likely to be affected by direct airflow, thereby reducing the risk of headache, dizziness, and general discomfort caused by the use of the indoor unit 100 of the air conditioner. It is beneficial to achieve indoor temperature rise or fall while protecting the user's health, and meet the user's usage needs.

[0083] Furthermore, the air diffuser 12 can partially or fully open the air outlet 112. When the air diffuser 12 partially opens the air outlet 112, it can achieve windless airflow in some areas and direct airflow in others, realizing zoned windless airflow. For example, the part of the air outlet 112 directly opposite the user's space can be blocked by the air diffuser 12, which can meet the user's need for windless airflow and the need for heating or cooling efficiency of the air conditioner indoor unit 100, thus achieving both zoned windless airflow and high-efficiency heating or cooling. When the air diffuser 12 fully opens the air outlet 112, the heating or cooling efficiency of the air conditioner indoor unit 100 is greater, and the indoor temperature rises or falls faster, reducing the waiting time for the user to wait for the indoor temperature to adjust to a comfortable temperature after turning on the air conditioner indoor unit 100, thus improving the user experience.

[0084] According to the embodiment of this utility model, the air outlet device 10 can realize windless air outlet, windless air outlet in different zones, and direct airflow at the air outlet 112. The air outlet has a variety of forms, which helps to meet the needs of more users and improve the user experience.

[0085] In some embodiments of this utility model, such as Figures 1-4As shown, both the air outlet panel 11 and the diffuser plate 12 are arc-shaped plates, with the first direction F1 being the arc-shaped extension direction of the plate. The diffuser plate 12 is slidable along the arc-shaped extension direction, allowing it to gradually open or close the air outlet 112 during sliding. This facilitates user observation of the area of ​​the air outlet 112 that is opened or closed by the diffuser plate 12, and allows the diffuser plate 12 to stop after opening or closing the air outlet 112 to the user's desired state, simplifying operation. Furthermore, sliding the diffuser plate 12 along the extension direction of the air outlet panel 11 reduces the space occupied by the diffuser plate 12 in the direction perpendicular to the extension direction of the air outlet panel 11, i.e., reduces the thickness of the diffuser plate 12. This reduces the space required for the diffuser plate 12 to slide, improving the structural compactness of the air outlet device 10.

[0086] Both the air outlet panel 11 and the air diffuser 12 are curved plates, so that the shapes of the air outlet panel 11 and the air diffuser 12 correspond and the air diffuser 12 can completely cover the entire air outlet 112. This helps to reduce the possibility of direct airflow at the air outlet 112 when the air diffuser 12 completely covers the air outlet 112, thus achieving a better effect of windless airflow.

[0087] In some embodiments of this utility model, such as Figures 3-10 As shown, a connecting seat 15 is connected to the inner side of the air outlet panel 11. The connecting seat 15 is arranged around the air outlet 112 and is used to connect the air duct component 30 of the indoor unit 100 of the air conditioner. The connecting seat 15 connects the air outlet panel 11 to the outer side of the air duct component 30 so that the airflow in the air duct component 30 flows to the outside through the air outlet 112 of the air outlet panel 11. The connecting seat 15 is arranged around the air outlet 112, which can firmly connect the edge of the air outlet 112 to the air duct component 30, reduce the possibility of air leakage between the air outlet panel 11 and the air duct component 30, and allow more airflow in the air duct component 30 to flow to the air outlet 112 and then to the outside, which helps to improve the heating or cooling efficiency of the indoor unit 100 of the air conditioner.

[0088] like Figures 5-12 As shown, a socket 151 is provided between the connecting seat 15 and the air outlet panel 11, which facilitates the placement of a portion of the diffuser plate 12 at the socket 151 to position the diffuser plate 12 inside the air outlet panel 11. Specifically, the diffuser plate 12 includes a body portion 121 with multiple air dissipation holes disposed thereon. During the sliding of the diffuser plate 12 along the first direction F1, the body portion 121 passes through the socket 151 to open or block the air outlet 112. This design allows the air outlet panel 11 to be connected to the duct component 30 via the connecting seat 15 while simultaneously avoiding the body portion 121 through the socket 151. This provides space for the diffuser plate 12 to slide within the socket 151, resulting in a relatively simple structure and enabling a tight fit between the multiple structures of the air outlet device 10, thus improving the structural compactness of the air outlet device 10.

[0089] In some embodiments, such as Figures 1-2 and Figures 5-10 As shown, the length of the main body 121 extends along the second direction F2 of the air outlet panel 11. The second direction F2 can be parallel to the length of the air outlet panel 11 or at a certain angle. For example, if the second direction F2 is parallel to the length of the air outlet panel 11, the larger part of the main body 121 extends along the length of the air outlet panel 11, which helps to increase the size of the main body 121 along the second direction F2, so that the main body 121 can more completely block the entire air outlet 112, resulting in a better windless air outlet effect.

[0090] like Figures 5-8 and 11- Figure 12 As shown, the air diffuser 12 also includes a connecting portion 122, which is connected to at least one end of the main body 121 along its length. The first drive motor 13 is connected to the connecting portion 122 via a first transmission mechanism 14. This allows the first drive motor 13 and the first transmission mechanism 14 to be located on one side of the main body 121 along its length, eliminating the need to occupy space in the main body 121 used for air diffusers. This facilitates ensuring that the number and size of the air diffusers meet requirements, resulting in a better, windless airflow effect.

[0091] In some embodiments, such as Figures 1-4 and Figures 5-10 As shown, both the air outlet panel 11 and the air diffuser 12 are arc-shaped plates. The first direction F1 is the arc-shaped extension direction of the plate, and the second direction F2 is parallel to the axial direction of the cylindrical surface of the arc-shaped plate, making the first direction F1 and the second direction F2 perpendicular. The air diffuser 12 is slidable along the first direction F1, and the length direction of the body 121 extends along the second direction F2. This reduces the size of the air diffuser 12 along the first direction F1, which helps to reduce the required movement space of the air diffuser 12 in the first direction F1 and improves the structural compactness of the air outlet device 10.

[0092] The connecting seat 15 is connected to the air outlet panel 11, and the body portion 121 of the diffuser 12 is located between the connecting seat 15 and the air outlet panel 11. The connecting portion 122 of the diffuser 12 is located on the side of the connecting seat 15 away from the air outlet 112 and the body portion 121. This causes the portion between the body portion 121 and the connecting portion 122 to interfere with the portion of the connecting seat 15 connected to the air outlet panel 11 during the sliding process of the diffuser 12 relative to the connecting seat 15 and the air outlet panel 11, hindering the sliding of the diffuser 12. However, in some embodiments of this utility model, such as... Figures 5-8 and Figures 11-12As shown, an open clearance groove 123 is defined between the connecting part 122 and the main body part 121. The clearance groove 123 is used to avoid the connecting seat 15, so that the diffuser plate 12 is less likely to interfere with the position of the connecting seat 15 during the sliding process, and the process of the diffuser plate 12 sliding to block or open the air outlet 112 is smoother and the air outlet effect is better.

[0093] In some embodiments of this utility model, such as Figures 5-8 and Figures 13-17 As shown, the first transmission mechanism 14 includes a first active transmission member 141 and a first driven transmission member 142. The first drive motor 13 and the first active transmission member 141 are disposed on the connecting seat 15, and the first driven transmission member 142 is disposed on the connecting part 122.

[0094] Through the transmission connection between the first active transmission member 141 and the first driven transmission member 142, the first drive motor 13 drives the first active transmission member 141 to move, thereby driving the first driven transmission member 142 to move, and in turn causing the connecting part 122 to slide relative to the connecting seat 15. This allows the first drive motor 13 to indirectly cooperate with the air diffuser 12, enabling flexible adjustment of the relative positions of the first drive motor 13 and the air diffuser 12 through the first active transmission member 141 and the first driven transmission member 142. This makes the placement of the first drive motor 13 and the air diffuser 12 more flexible, adapting to the installation positions of other structures within the air conditioner indoor unit 100, and improving the structural compactness of the components within the air conditioner indoor unit 100.

[0095] The first drive motor 13 and the first active transmission component 141 are located on the connecting seat 15, so that the first drive motor 13 and the first active transmission component 141 do not need to slide together during the process of the air diffuser 12 sliding relative to the connecting seat 15, which can reduce the load on the air diffuser 12 and make it easier to drive the air diffuser 12 to slide.

[0096] In some embodiments, such as Figures 5-8 and Figures 11-12 As shown, the first driving transmission element 141 includes one or more first gears 1411, for example... Figure 6 and Figure 8 The first active transmission component 141 shown includes two first gears 1411, and the first driven transmission component 142 includes a first rack 1421. The driving force of the first drive motor 13 is transmitted through the meshing of the first gears 1411 and the first rack 1421, achieving high transmission accuracy and facilitating precise control of parameters such as the sliding speed of the diffuser plate 12. For example, adjusting the size and number of the first gears 1411 allows for flexible adjustment of the relative position of the connecting seat 15 and the diffuser plate 12. Adjusting parameters such as the number of teeth of the first gears 1411 and the first rack 1421 allows for adjustment of the transmission ratio of the first transmission mechanism 14, facilitating the adjustment of the sliding speed of the diffuser plate 12.

[0097] The length of the connecting part 122 extends along the first direction F1. One end of the connecting part 122 is connected to the main body part 121 through the connecting rib 124. The first rack 1421 is provided on the connecting part 122 and extends along the length of the connecting part 122. The length of the first rack 1421 can be extended to extend the sliding path of the connecting part 122 along the first direction F1, that is, to extend the activity space of the diffuser plate 12, which is conducive to making the diffuser plate 12 fully open or completely block the air outlet 112.

[0098] In some embodiments of this utility model, such as Figures 5-8 and Figure 11 As shown, at the same air diffuser 12, there are two connecting parts 122 and two first drive motors 13. The two connecting parts 122 are connected to both ends of the main body 121 along its length. The two first drive motors 13 are respectively connected to the two first transmission mechanisms 14 in a one-to-one manner, and the two first drive motors 13 are respectively connected to the two connecting parts 122 in a one-to-one manner, so that the two first drive motors 13 are respectively connected to the two connecting parts 122 in a one-to-one manner. With the two first drive motors 13, the air diffuser 12 can be driven to slide simultaneously at both ends of its length, and the air diffuser 12 is subjected to a greater driving force, making it easier to drive the air diffuser 12 to slide.

[0099] In some embodiments, such as Figure 2 , Figure 10 and Figure 12 As shown, at the same air diffuser 12, the main body 121 has a connecting part 122 at one end along its length and a sliding part or rolling part 125 at the other end. The connecting part 122 can be connected to the first drive motor 13 for transmission. The sliding part or rolling part 125 is used to movably engage with the groove 32 on the connecting seat 15 or the air duct component 30. Specifically, the sliding part slidably engages with the groove 32, and the rolling part 125 rolls with the groove 32. The friction between the rolling part 125 and the groove 32 is relatively small, making the rolling engagement of the rolling part 125 easier and less strenuous, and the rolling part 125 moves more easily along the first direction F1 with the main body 121. The connecting seat 15 is connected to the air duct component 30, and the groove 32 can be located on the connecting seat 15 or the air duct component 30. The rolling part 125 can be a bearing or other component.

[0100] To make the following description more concise, the example given is that the main body 121 has a rolling part 125 at the other end along its own length and the air duct component 30 has a groove 32. According to the following description, an embodiment in which the main body 121 has a sliding part at the other end along its own length and the connecting seat 15 has a groove 32 is also readily available.

[0101] The first drive motor 13 drives the connecting part 122 to slide through the first transmission mechanism 14, so that the connecting part 122 and the main body 121 are subjected to a driving force for sliding along the first direction F1. This causes the rolling part 125 to roll into contact with the groove 32, so that the rolling part 125 moves together with the main body 121 along the first direction F1. The rolling part 125 provides an auxiliary function for the sliding of the diffuser plate 12. By providing a driving force to the diffuser plate 12 through the first drive motor 13 and the rolling part 125 rolling into contact with the groove 32 along with the main body 121, the diffuser plate 12 as a whole slides along the first direction F1. This eliminates the need for one first drive motor 13, reduces the number of first drive motors 13, reduces the installation space required for the first drive motor 13, and lowers the cost of the air outlet device 10.

[0102] In some embodiments of this utility model, such as Figures 5-8 and Figure 11 As shown, there is only one diffuser 12. This diffuser 12 allows for easy full opening or blocking of the entire air outlet 112, resulting in better airflow. Furthermore, controlling the sliding of only one diffuser 12 simplifies the structure and makes it easy to implement. For example, in some embodiments, such as... Figures 5-8 and Figure 17 As shown, the air outlet 112 is a complete air outlet area 1121, and a diffuser 12 is matched with an air outlet 112.

[0103] In other embodiments, such as Figure 2 , Figure 10 and Figure 12 As shown, there are multiple air diffusers 12, which are arranged in the second direction F2. The multiple air diffusers 12 are used to open or block different areas of the air outlet 112 respectively, which is conducive to realizing the zoned air supply of the indoor unit 100 of the air conditioner according to the user's needs and to meet the user's usage requirements.

[0104] For example, in some embodiments, such as Figure 2 , Figures 9-10 , Figure 12 and Figure 16 As shown, the air outlet 112 includes multiple air outlet zones 1121, which are arranged in the second direction F2. Multiple diffuser panels 12 correspond one-to-one with the positions of the multiple air outlet zones 1121, and each diffuser panel 12 is used to open or block its corresponding air outlet zone 1121. By controlling the state of each diffuser panel 12 opening or blocking its corresponding air outlet zone 1121, each air outlet zone 1121 can be controlled to be in a windless air outlet state or a direct airflow state. By adjusting parameters such as the number and area of ​​the multiple air outlet zones 1121 and the diffuser panels 12, the position and size of the corresponding air outlet area of ​​each air outlet zone 1121 can be adjusted to achieve precise air delivery to multiple air outlet areas, thus meeting user needs.

[0105] In some embodiments of this utility model, such as Figures 1-9 and Figures 16-17 As shown, the air outlet panel 11 includes a first wind deflector 111 and a second wind deflector 113, which are arranged in a first direction F1. The air outlet 112 is located between the first wind deflector 111 and the second wind deflector 113. The first wind deflector 111 and the second wind deflector 113 along both sides of the outlet 312 in the first direction F1 can shield the internal structure of the air conditioner indoor unit 100, reducing the possibility of external dust or small stones and other impurities entering the air conditioner indoor unit 100 and damaging its internal structure, thus protecting the air conditioner indoor unit 100.

[0106] like Figures 3-8 As shown, the inlet 151 is located between the first windbreak part 111 and the connecting seat 15. When the diffuser plate 12 is in the state of having its air outlet 112 open, the main body part 121 is located inside the first windbreak part 111 so that the diffuser plate 12 is blocked by the first windbreak part 111. This makes it difficult for the diffuser plate 12 to be exposed when its air outlet 112 is open, reducing the possibility of external impurities blocking the diffuser hole, making the diffuser plate 12 slide more smoothly, and the air outlet 112 is blocked by the diffuser plate 12, resulting in a better windless air outlet effect.

[0107] In some embodiments, such as Figure 4 and Figure 10 As shown, in the first direction F1, the size of the main body 121 is greater than or equal to the size of the air outlet 112, so that the diffuser 12 can completely block the air outlet 112 when it is in the state of blocking the air outlet 112, reducing other air leakage areas besides the air outlet hole, and making the windless air outlet 112 more effective. The size of the main body 121 is less than or equal to the size of the first wind baffle 111, so that when the diffuser 12 is in the state of opening the air outlet 112, the first wind baffle 111 can completely block the part of the diffuser 12 that is not opposite to the air outlet 112, making the diffuser 12 less likely to be exposed and blocked by impurities, which helps to protect the diffuser 12 and ensure a better windless air outlet effect when the diffuser 12 blocks the air outlet 112.

[0108] In some embodiments of this utility model, such as Figures 5-8As shown, one of the inner side of the air outlet panel 11 and the air diffuser 12 has a limiting groove 114 extending along the first direction F1, and the other has a limiting part 1221 that cooperates with the limiting groove 114. Through the cooperation of the limiting groove 114 and the limiting part 1221, the sliding of the air diffuser 12 relative to the air outlet panel 11 can be guided, so that the sliding of the air diffuser 12 is not easily deviated in directions other than the first direction F1. Under the drive of the first drive motor 13, the air diffuser 12 can accurately open or block part or all of the air outlet 112, and the air outlet effect is more controllable.

[0109] For example, in some embodiments, such as Figures 5-8 As shown, the inner side of the air outlet panel 11 has a limiting groove 114, and a part of the connecting part 122 is a limiting part 1221. There is no need to add a new structure to the air diffuser 12 to form the limiting part 1221. The limiting part 1221 can be formed by the connecting part 122 itself and can cooperate with the limiting groove 114, which helps to simplify the structure of the air outlet device 10.

[0110] In some embodiments where the number of air diffuser plates 12 is one, such as Figures 5-8 and Figure 11 As shown, the air outlet panel 11 has two limiting grooves 114, and the air diffuser 12 has two limiting parts 1221. The two limiting grooves 114 and the two limiting parts 1221 are matched one-to-one to limit the air diffuser 12 between the two limiting grooves 114, so that the air diffuser 12 is not easily deviated in any direction other than the first direction F1 during the sliding process, and the operation of the air diffuser 12 to block or open the air outlet 112 is more stable.

[0111] In some embodiments where the number of air diffuser plates 12 is two, such as Figures 9-10 and Figure 12 As shown, the air outlet panel 11 has two limiting grooves 114, and the two air diffusers 12 each have a limiting part 1221. One end of each air diffuser 12 is engaged with the limiting groove 114, and the other end is limited by other structures such as the groove 32 of the air duct component 30, so as to limit the two air diffusers 12 between the two limiting grooves 114, so that the air diffusers 12 are not easily deviated in other directions other than the first direction F1 during the sliding process.

[0112] An indoor air conditioning unit 100 according to an embodiment of the present invention includes a housing 20, an air duct component 30, and an air outlet device 10 according to an embodiment of the present invention. The housing 20 may be provided with an air inlet 211, allowing outside airflow to flow into the indoor air conditioning unit 100 through the air inlet 211. The air duct component 30 is disposed within the housing 20 and defines an air outlet duct 31, for example, in some embodiments, such as... Figures 3-4As shown, the air duct component 30 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 31 is defined inside the air duct volute.

[0113] The inner side of the air outlet panel 11 in the air outlet device 10 is connected to the air duct component 30, and the air outlet 112 is opposite to and connected to the outlet 312 of the air duct 31. The air duct 31 is a channel for airflow. The inlet 311 of the air duct 31 can be connected to the air inlet 211, and the outlet 312 of the air duct 31 can be connected to the air outlet 112, so that the airflow flowing into the indoor unit 100 of the air conditioner through the air inlet 211 can flow into the air duct 31 through the inlet 311 and flow to the air outlet 112 through the outlet 312 to flow to the outside.

[0114] Since the air outlet device 10 according to the present utility model embodiment has the above-mentioned beneficial technical effects, the air conditioner indoor unit 100 according to the present utility model embodiment can realize whole-area windless air outlet, zoned windless air outlet and direct air blowing at the air outlet 112, with diverse air outlet forms, which is conducive to meeting the usage needs of more users and improving the user experience.

[0115] In some embodiments, such as Figures 2-4 , Figure 15 and Figures 18-19 As shown, the indoor unit 100 of the air conditioner also includes an indoor fan 41 and an indoor heat exchanger 42. Both the indoor fan 41 and the indoor heat exchanger 42 are housed within the casing 20. The indoor fan 41 is located at the inlet 311 of the air duct 31, and the indoor heat exchanger 42 is located between the indoor fan 41 and the air inlet 211 in the direction of airflow. The indoor fan 41 can be a cross-flow impeller, which can rotate under the drive of a motor. The indoor heat exchanger 42 can be an evaporator, allowing the airflow flowing from the air inlet 211 to the inlet 311 to first pass through the indoor heat exchanger 42 for heat exchange. Combined with the indoor fan 41, this ensures that as much heat as possible is exchanged on all the airflow flowing towards the inlet 311, converting cold air into hot air or hot air into cold air. The heat-exchanged airflow enters the air duct 31 and flows out from the air outlet 112 through the outlet 312, thus realizing the cooling or heating function of the indoor unit 100 for the outside environment.

[0116] In some embodiments, the indoor fan 41 is a cross-flow impeller, and a mounting base is provided on each of the left and right sides of the air duct component 30. The cross-flow impeller can be rotatably connected to the air duct 31 assembly through the mounting base. One of the mounting bases has a small notch and is nearly 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 mounting base.

[0117] In some embodiments, such as Figures 2-4 and Figures 18-19As shown, the indoor unit 100 of the air conditioner also includes a heater 421, which is located in the indoor heat exchanger 42. The heater 421 can be turned on when the indoor unit 100 of the air conditioner is in heating operation to provide auxiliary heating and improve heating efficiency.

[0118] In some embodiments, such as Figures 1-4 and Figures 18-19 As shown, the air duct component 30 is movably disposed within the housing 20. For example, the air duct component 30 is rotatable, movable, or both rotatable and movable within the housing 20. Furthermore, in some embodiments, such as... Figure 2 , Figure 15 and Figure 20 As shown, the indoor unit 100 of the air conditioner also includes a chassis 43, which is located inside the housing 20. The chassis 43 can be used to install components such as the air duct component 30, the indoor fan 41, and the indoor heat exchanger 42.

[0119] For example, in some specific embodiments, such as Figures 3-4 and Figures 18-19 As shown, the air duct component 30 is rotatably mounted on the chassis 43 inside the housing 20, and the air duct component 30 can be... Figures 3-4 Rotate to the state shown Figures 18-19 The state shown.

[0120] The inner side of the air outlet panel 11 is connected to the air duct component 30, and the air diffuser 12 is slidably disposed on the inner side of the air outlet panel 11, so that the air outlet panel 11 and the air diffuser 12 can move relative to the housing 20 together with the air duct component 30, which is conducive to achieving zoned air outlet in a larger air outlet range.

[0121] In some related technologies, the indoor unit of an air conditioner has an air guide vane at the outlet of the air duct. The vane rotates relative to the air duct components to achieve multi-directional airflow. However, the outlet position of the air duct is fixed, and the limited range of motion of the air guide vane results in a small airflow distribution range, making it difficult to meet users' needs for airflow in multiple directions. Furthermore, during the process of guiding airflow, the 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.

[0122] This application allows the air duct component 30, the diffuser plate 12, and the air outlet panel 11 to move together relative to the housing 20, thereby changing the position of the outlet 312 of the air duct 31. This changes the position of the air outlet 112, directly altering the airflow direction at the outlet 112, achieving multi-directional airflow. The airflow range is large, easily meeting users' needs for airflow in multiple directions. Furthermore, directly changing the position of the air outlet 112 to alter the airflow direction minimizes airflow obstruction and airflow loss, increasing airflow volume and reducing noise, thus improving the user experience.

[0123] To make the following description more concise, we will use the example of the air duct component 30 being rotatably disposed within the housing 20.

[0124] In some embodiments, such as Figures 2-4 and Figures 18-19 As shown, the housing 20 has an opening 23, and the air outlet panel 11 is located at the opening 23 and on the outside of the housing 20. During the rotation of the air duct component 30, the air outlet panel 11 blocks part of the opening 23 to reduce the entry of external impurities into the interior of the air conditioning indoor unit 100. The air outlet panel 11 opens the part of the opening 23 opposite to the air outlet 112 to facilitate air outlet.

[0125] In some embodiments, such as Figures 2-4 and Figures 18-19 As shown, in the first direction F1, the size of the opening 23 is larger than the size of the air outlet 112, allowing the air outlet 112 to be opposite different parts of the opening 23 during the rotation of the air duct component 30, thus achieving multi-directional airflow. In the first direction F1, the size of the opening 23 is smaller than the size of the air outlet panel 11, allowing the air outlet panel 11 to completely block the portion of the opening 23 that is not opposite the air outlet 112, reducing the possibility of external impurities entering the indoor unit 100 of the air conditioner and helping to protect the indoor unit 100.

[0126] The movement of the air duct component 30 can be controlled electronically. For example, when the air duct component 30 moves to a state where a specific part of the air outlet 112 and the opening 23 are opposite to and connected, the air duct component 30 can be stopped from rotating. Alternatively, the air duct component 30 can be limited by a mechanical structure.

[0127] For example, in some embodiments, such as Figures 2-4 and Figures 18-19 As shown, the opening 23 has a first edge 231 and a second edge 232 disposed opposite to each other in a first direction F1, and the air outlet panel 11 includes a first wind deflector 111 and a second wind deflector 113. When the air duct component 30 abuts against the first edge 231, the second wind deflector 113 blocks a portion of the opening 23, and when the air duct component 30 abuts against the second edge 232, the first wind deflector 111 blocks a portion of the opening 23.

[0128] The first edge 231 and the second edge 232 can limit the air duct component 30 and thus limit the air outlet panel 11, so that the air duct component 30 stops rotating when the air outlet 112 and the open opening 23 are opposite each other along the first direction F1. This improves the control accuracy of the movement of the air duct component 30 and makes the first wind deflector 111 and the second wind deflector 113 block the part of the open opening 23 that is not opposite to the air outlet 112, which helps to protect the indoor unit 100 of the air conditioner.

[0129] For example, in some specific embodiments, such as Figure 2 As shown, the housing 20 includes a face frame 21 and a front panel 22. The front panel 22 covers the upper front side of the face frame 21. The lower surface of the front panel 22 is formed as a first edge 231, and the lower front surface of the face frame 21 is formed as a second edge 232.

[0130] In some embodiments, such as Figure 19 As shown, in the first direction F1, the sum of the dimensions of the first windbreak 111 and the air outlet 112 is greater than or equal to the dimension of the open opening 23. When the air duct component 30 is rotated to a position where it abuts against the second edge 232, the first windbreak 111 can block the part of the open opening 23 that is not opposite to the air outlet 112, and the diffuser 12 can open or block the part of the open opening 23 that is opposite to the air outlet 112, thereby reducing the possibility of airflow leaking outward from the part of the open opening 23 that is not opposite to the air outlet 112, and making the air outlet direction at the air outlet 112 more controllable.

[0131] like Figure 4 As shown, the sum of the dimensions of the second windbreak 113 and the air outlet 112 is greater than or equal to the dimension of the open opening 23. When the air duct component 30 is rotated to a position where it abuts against the first edge 231, the second windbreak 113 can block the part of the open opening 23 that is not opposite to the air outlet 112. The diffuser 12 opens or blocks the part of the open opening 23 that is opposite to the air outlet 112, reducing the possibility of airflow leakage from the part of the open opening 23 that is not opposite to the air outlet 112, and making the air outlet direction at the air outlet 112 more controllable.

[0132] In some embodiments, such as Figure 2 , Figure 15 and Figures 20-21 As shown, the indoor unit 100 of the air conditioner also includes a second transmission mechanism 72 and a second drive motor 71. The second drive motor 71 is connected to the duct component 30 via the second transmission mechanism 72 to drive the duct component 30 to rotate. The second drive motor 71 can be a stepper motor, AC motor, DC motor, or other types of motor, and the second transmission mechanism 72 can be a gear and rack assembly, a slide rail and slider assembly, a ball screw, etc. The second transmission mechanism 72 transmits the driving force of the second drive motor 71 to the duct component 30 to drive the duct component 30 to rotate, which facilitates flexible adjustment of the relative positions of the second drive motor 71 and the duct component 30, making the installation positions of the second drive motor 71 and the duct component 30 more flexible, so as to adapt to the installation positions of other structures within the indoor unit 100 of the air conditioner, and improve the structural compactness of the components within the indoor unit 100 of the air conditioner.

[0133] The second transmission mechanism 72 includes a second active transmission component 721 and a second driven transmission component 722 connected by a transmission link. A second drive motor 71 and the second active transmission component 721 are located on the housing 20, and the second driven transmission component 722 is located on the air duct component 30. Through the transmission connection between the second active transmission component 721 and the second driven transmission component 722, the second drive motor 71 drives the second active transmission component 721 to move, thereby causing the second driven transmission component 722 to move, and consequently causing the air duct component 30 to rotate relative to the housing 20. This indirect cooperation between the second drive motor 71 and the air duct component 30 allows for flexible adjustment of their relative positions via the second active transmission component 721 and the second driven transmission component 722. This makes the placement of the second drive motor 71 and the air duct component 30 more flexible, adapting to the installation positions of other structures within the air conditioner indoor unit 100 and improving the structural compactness of the components within the air conditioner indoor unit 100.

[0134] The second drive motor 71 and the second active transmission component 721 are located on the housing 20, so that the second drive motor 71 and the second active transmission component 721 do not need to rotate together during the rotation of the air duct component 30 relative to the housing 20, which can reduce the load on the air duct component 30 and make it easier to drive the air duct component 30 to slide.

[0135] In some embodiments, such as Figure 2 , Figure 15 and Figures 20-21 As shown, the second active transmission component 721 includes at least one second gear 7211, and the second driven transmission component 722 includes a second rack 7221 extending along the first direction F1. The driving force of the second drive motor 71 is transmitted through the meshing of the second gear 7211 and the second rack 7221, achieving high transmission accuracy and facilitating precise control of parameters such as the rotational speed of the air duct component 30. For example, adjusting the size and number of the second gear 7211 allows for flexible adjustment of the relative position of the housing 20 and the air duct component 30, and adjusting parameters such as the number of teeth of the second gear 7211 and the second rack 7221 allows for adjustment of the transmission ratio of the second transmission mechanism 72, facilitating the adjustment of the rotational speed of the air duct component 30.

[0136] In some embodiments, such as Figures 2-4 and Figures 18-19 As shown, the indoor unit 100 of the air conditioner also includes a sway vane assembly 50, which is disposed in the air duct component 30 and moves together with the air duct component 30. The sway vane assembly 50 includes a drive component and multiple sway vanes 51, which are oscillatingly disposed within the air duct 31. The drive component drives the multiple sway vanes 51 to rotate synchronously. By oscillating the sway vanes 51 relative to the air duct 31, and by allowing the sway vanes 51 to move together with the air duct component 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.

[0137] In some embodiments, such as Figure 2 As shown, the air outlet 112 includes multiple air outlet zones 1121 and multiple sway blade assemblies 50. The positions of the multiple sway blade assemblies 50 and the multiple air outlet zones 1121 are one-to-one, and the air outlet direction of the multiple air outlet zones 1121 can be adjusted respectively to achieve different air outlet directions of different air outlet zones 1121, which is conducive to meeting the user's demand for air outlet of the air conditioner indoor unit 100 in more directions.

[0138] For example, in some embodiments, such as Figures 1-4 and Figures 22-27 As shown, the air outlet 112 includes two air outlet zones 1121, and there are two diffusers 12 and two sway vane assemblies 50. The positions of the two diffusers 12 and the two air outlet zones 1121 correspond one-to-one, and the positions of the two sway vane assemblies 50 and the two air outlet zones 1121 also correspond one-to-one. By adjusting the state of the two diffusers 12 opening or blocking the corresponding air outlet zones 1121, and by adjusting the swing direction of the sway vanes 51 contained in each of the two sway vane assemblies 50, different operating modes of the indoor unit 100 can be achieved to meet more air outlet needs of users.

[0139] For example Figure 23 As shown, adjusting both diffusers 12 to open the corresponding air outlet zones 1121 causes the blades 51 of each of the two oscillating assemblies 50 to swing forward, entering the normal mode of the indoor unit 100. This ensures that the airflow at the air outlet 112 blows directly forward, resulting in high heating or cooling efficiency of the indoor unit 100.

[0140] For example Figure 24 As shown, adjusting both diffusers 12 opens the corresponding air outlet zones 1121, and the vanes 51 of each of the two oscillating assemblies 50 swing to both sides. For example, the vanes 51 of the left oscillating assemblies 50 swing to the left, and the vanes 51 of the right oscillating assemblies 50 swing to the right, entering the direct-blowing, windless mode of the indoor unit 100. This directs the airflow at the air outlet 112 to both sides, resulting in high heating or cooling efficiency of the indoor unit 100, and users located in front of the indoor unit 100 are less likely to be exposed to direct airflow, making the user experience more comfortable.

[0141] For example Figure 25 As shown, by adjusting both air diffusers 12 to block the corresponding air outlet areas 1121, the air conditioner indoor unit 100 enters the all-area windless mode. This causes the large airflow at the air outlet 112 to be divided into multiple smaller airflows before being blown outwards, reducing the user's direct airflow and making the user feel more comfortable.

[0142] For example Figure 26As shown, adjusting the left diffuser 12 to block the left air outlet area 1121 and the right diffuser 12 to open the right air outlet area 1121 causes the oscillator 51 to swing to the right, entering the zoned windless mode of the indoor unit 100. This causes the large airflow on the left side of the air outlet 112 to be divided into multiple smaller airflows and blown outwards by the diffuser holes, while the airflow on the right side of the air outlet 112 blows directly to the right. This results in high heating or cooling efficiency of the indoor unit 100, and users located in front of and to the left of the indoor unit 100 are less likely to be exposed to direct airflow, making the user experience more comfortable.

[0143] For example Figure 27 As shown, adjusting the left diffuser 12 opens the left air outlet area 1121, while the right diffuser 12 blocks the right air outlet area 1121. The oscillating blades 51 swing to the left, entering the zoned windless mode of the indoor unit 100. This directs the airflow from the left side of the air outlet 112 directly to the left, while the large airflow from the right side of the air outlet 112 is divided into multiple smaller airflows by the diffuser holes before being blown outwards. This results in high heating or cooling efficiency of the indoor unit 100, and users located in front of and to the right of the indoor unit 100 are less likely to experience direct airflow, making the user experience more comfortable.

[0144] An 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 can achieve omnidirectional windless airflow, zoned windless airflow, and direct airflow at the air outlet 112, providing diverse airflow patterns to meet the needs of more users and improve the user experience.

[0145] The following describes in detail, with reference to the accompanying drawings, a specific embodiment of the air outlet device 10, the air conditioner indoor unit 100, and the air conditioner according to the present invention. It should be understood that the following description is merely illustrative and should not be construed as limiting the present invention.

[0146] like Figures 1-4 , Figures 9-10 , Figures 12-16 and Figures 18-27 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 an air outlet device 10, a casing 20, an air duct component 30, an indoor fan 41, an indoor heat exchanger 42, a chassis 43, a louver assembly 50, a second drive motor 71, and a second transmission mechanism 72.

[0147] The housing 20 includes a face frame 21 and a front panel 22. The face frame 21 has an air inlet 211, and the front panel 22 covers the upper front side of the face frame 21. The chassis 43 is disposed inside the housing 20. The air duct component 30 is rotatably disposed on the chassis 43 via a second drive motor 71 and a second transmission mechanism 72. The air duct component 30 defines an air duct 31, and the inlet 311 of the air duct 31 communicates with the air inlet 211.

[0148] The second drive motor 71 is connected to the air duct component 30 via the second transmission mechanism 72. The second transmission mechanism 72 includes a second active transmission component 721 and a second driven transmission component 722 connected by transmission. The second active transmission component 721 includes a second gear 7211, and the second driven transmission component 722 includes a second rack 7221 extending along the first direction F1 of the air outlet panel 11. The second drive motor 71 and the second gear 7211 are located in the chassis 43 inside the housing 20, and the second rack 7221 is located in the air duct component 30.

[0149] The oscillating blade assembly 50 is disposed on the air duct component 30 and rotates together with the air duct component 30. The oscillating blade assembly 50 includes a driving component and multiple oscillating blades 51. The multiple oscillating blades 51 are oscillatingly disposed in the air duct 31. The driving component of the oscillating blade assembly 50 drives the multiple oscillating blades 51 of the same oscillating blade assembly 50 to oscillate synchronously.

[0150] The air outlet device 10 includes an air outlet panel 11, a diffuser 12, a first drive motor 13, a first transmission mechanism 14, and a connecting seat 15. The air outlet panel 11 is located on the lower front side of the face frame 21 and covers the outer side of the housing 20. The air outlet panel 11 includes a first wind deflector 111, an air outlet 112, and a second wind deflector 113. The first wind deflector 111 and the second wind deflector 113 are arranged in a first direction F1, with the first wind deflector 111 located in front of and above the second wind deflector 113. The air outlet 112 is located between the first wind deflector 111 and the second wind deflector 113, and the air outlet 112 is opposite to and connected to the outlet 312 of the air duct 31.

[0151] The connector 15 is connected to the inside of the air outlet panel 11 and to the air duct component 30. The connector 15 is arranged around the air outlet 112, and there is a socket 151 between the connector 15 and the air outlet panel 11.

[0152] A diffuser plate 12 is slidably disposed on the inner side of the air outlet panel 11 along a first direction F1 to open or block the air outlet 112. The diffuser plate 12 includes a body portion 31, a connecting portion 32, and a rolling portion 35. The body portion 121 has a plurality of spaced-apart diffuser holes, and its length extends along a second direction F2 of the air outlet panel 11. One end of the body portion 31 along its own length is connected to the connecting portion 32 via a connecting rib 34, and the other end is provided with a rolling portion 35. The connecting portion 32 is used to connect with the first transmission mechanism 62, and the rolling portion 35 is used to movably engage with the groove 122 of the air duct component 12. The connecting portion 32 is located on the side of the connecting seat 15 away from the air outlet 112, and a clearance groove 33 with an open opening is defined between the connecting portion 32 and the body portion 31. The clearance groove 33 is used to avoid the connecting seat 15. The length of the connecting part 32 extends along the first direction F1, and one end of the connecting part 32 in the length direction is connected to the main body part 31 through the connecting rib 34.

[0153] The insertion port 151 is located between the first windbreak portion 111 and the connecting seat 15. During the sliding of the diffuser plate 12 along the first direction F1, the main body portion 121 passes through the insertion port 151 to open or block the air outlet 112. When the diffuser plate 12 has the air outlet 112 open, the main body portion 121 is located inside the first windbreak portion 111. In the first direction F1, the size of the main body portion 121 is greater than or equal to the size of the air outlet 112, and the size of the main body portion 121 is less than or equal to the size of the first windbreak portion 111.

[0154] The first drive motor 13 is connected to the connecting portion 122 of the air diffuser 12 via the first transmission mechanism 14. The first drive motor 13 drives the air diffuser 12 to slide along the first direction F1. The first transmission mechanism 14 includes a first driving transmission member 141 and a first driven transmission member 142. The first drive motor 13 and the first driving transmission member 141 are disposed on the connecting seat 15, and the first driven transmission member 142 is disposed on the connecting portion 122. The first driving transmission member 141 includes two gears, and the first driven transmission member 142 includes a first rack 1421 extending along the first direction F1.

[0155] There are two diffuser panels 12, arranged in the second direction F2, and each diffuser panel 12 is used to open or block different areas of the air outlet 112. There are also two oscillating blade assemblies 50, arranged in the second direction F2, and the oscillation of the oscillating blades 51 contained in each oscillating blade assembly 50 is independent of each other. The air outlet 112 includes two air outlet areas 1121 arranged along the second direction F2. The positions of the two diffuser panels 12 and the two air outlet areas 1121 correspond one-to-one, and the two diffuser panels 12 are used to open or block the two air outlet areas 1121 respectively. The positions of the two oscillating blade assemblies 50 and the two air outlet areas 1121 also correspond one-to-one, and the two oscillating blade assemblies 50 are used to guide the airflow of the corresponding air outlet area 1121.

[0156] The air outlet panel 11 has a limiting groove 114 extending along the first direction F1 at each end along the second direction F2. Each diffuser plate 12 has a limiting part 1221 at one end along the second direction F2 and a rolling part 125 at the other end, so that one end of the diffuser plate 12 cooperates with the limiting groove 114 through the limiting part 1221 and the other end cooperates with the groove 32 of the air duct component 30 through the rolling part 125, so as to limit the two diffuser plates 12 between the two limiting grooves 114. The rolling part 125 is a sliding bearing.

[0157] Both the air outlet panel 11 and the air diffuser panel 12 are arc-shaped panels. The first direction F1 is the arc-shaped extension direction of the arc-shaped panel, and the second direction F2 is parallel to the axial direction of the cylindrical surface where the arc-shaped panel is located.

[0158] Both the indoor fan 41 and the indoor heat exchanger 42 are located on the chassis 43. The indoor fan 41 is located at the inlet 311 of the air duct 31. In the direction of air flow, the indoor heat exchanger 42 is located between the indoor fan 41 and the air inlet 211.

[0159] The rotation axis of the indoor fan 41, the central axis of the cylindrical surface where the air outlet panel 11 is located, and the central axis of the cylindrical surface where the air diffuser 12 is located coincide with the rotation axis of the air duct component 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 component 30.

[0160] 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 211 and then flows through the indoor heat exchanger 42 for heat exchange. Combined with the indoor fan 41, the airflow entering from the air inlet 211 is heat exchanged as much as possible. The heat-exchanged airflow enters the air duct 31 through the inlet 311 and flows through the outlet 312 of the air duct 31 to the air outlet 112, and then flows to the outside through the air outlet 112.

[0161] During the operation of the indoor unit 100 of the air conditioner, the airflow sensation can be changed by sliding the diffuser 12, achieving either windless airflow or direct airflow. For example... Figure 4 , Figure 19 and Figure 25 As shown, the diffuser plate 12 blocks the air outlet 112, causing the large airflow at the air outlet 112 to be divided into multiple smaller airflows by multiple diffuser holes, achieving windless airflow throughout the entire area, making the user feel more comfortable.

[0162] For example Figure 3 , Figure 18 and Figures 23-24 As shown, the air diffuser 12 opens the air outlet 112, allowing the airflow at the air outlet 112 to flow directly to the outside, achieving normal mode airflow to the outside, and the heating or cooling efficiency of the air conditioner indoor unit 100 is high.

[0163] Of course, such as Figures 26-27 As shown, one diffuser 12 can be opened to the corresponding air outlet zone 1121, while the other diffuser 12 is closed to the corresponding air outlet zone 1121, achieving zoned airflow without a draft and meeting more user needs.

[0164] During the operation of the indoor unit 100 of the air conditioner, the air outlet direction can also be changed by the swing of the swivel blades 51 to achieve multi-directional air outlet. For example Figure 23 As shown, the blades 51 of both blade assemblies 50 are made to swing forward to achieve a direct airflow. For example... Figure 24 As shown, the oscillation directions of the oscillating blades 51 of the two oscillating blade assemblies 50 are opposite, achieving a direct, windless blowing effect. Of course, the oscillation directions of the oscillating blades 51 included in each of the two oscillating blade assemblies 50 can also be other directions to meet the air outlet requirements of more directions.

[0165] During the operation of the indoor unit 100 of the air conditioner, the airflow direction can be changed by rotating the duct component 30 to achieve vertical airflow. For example... Figures 3-4 In the indicated state, the air duct component 30 rotates until the air outlet 112 is at its highest position, causing the airflow to rise. In particular, during the cooling process, the upward airflow, coupled with the downward flow of cold air due to gravity, accelerates indoor air circulation, significantly improving the indoor cooling speed and temperature uniformity.

[0166] For example Figures 18-19 As shown, the air duct component 30 rotates until the air outlet 112 is at its lowest position, causing the airflow to be directed downwards. In particular, during heating operation, directing the hot air downwards and closer to the wall facilitates a stronger Coanda effect, making the hot air stream more concentrated and increasing the air volume. This results in better ground penetration of the hot air, a longer rolling distance along the ground, and, since hot air is lighter than cold air, it rises under the influence of gravity, increasing the rate of temperature rise in the foot warmer and the room, and significantly improving the uniformity of indoor temperature.

[0167] Of course, the air duct component 30 can also be rotated to a middle position where the air outlet 112 is neither at the top nor the bottom. By rotating the air duct component 30, the airflow direction can be changed, resulting in a large airflow range and enabling various air supply modes.

[0168] By sliding the two diffusers 12, swinging the blades 51 contained in each of the two oscillating blade assemblies 50, and rotating the duct component 30, multiple air outlet modes can be achieved to meet various user needs, making it highly practical.
