Description

[0001] This application claims priority to Chinese Patent Application No. 202511837584.2, filed on December 5, 2025, entitled "An Air Conditioner", the contents of which shall be construed as incorporated herein by reference. Technical Field

[0002] This application relates to, but is not limited to, the field of air handling equipment technology, specifically to a dual-outlet air conditioner. Background Technology

[0024] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0025] like Figures 1 to 6 As shown, this application embodiment provides a dual-outlet air conditioner, including: an indoor unit body 200 (e.g., Figure 7 and Figure 8 (as shown) and the air vent module 100 detachably connected to the indoor unit body 200 (as shown) Figures 9 to 13 (As shown).

[0026] The indoor unit body 200 includes a casing body 104, a heat exchanger 4, and a fan 3. The casing body 104 contains an air inlet heat exchange chamber 17 (e.g., ...). Figure 21 As shown, heat exchanger 4 and fan 3 are located inside air inlet heat exchange chamber 17. Heat exchanger 4 is located downstream of fan 3, and fan 3 is a centrifugal fan.

[0027] like Figures 9 to 13 As shown, the air outlet module 100 includes an air outlet housing 102 and an air guiding mechanism. An air outlet cavity 18 is provided inside the air outlet housing 102. The air outlet housing 102 is detachably connected to the main body 104 of the unit housing to form the housing 1 of the indoor unit. Therefore, the air outlet module 100 is a detachable module.

[0028] The air outlet cavity 18 is provided with a side air inlet 10 and a bottom air inlet 13. The air inlet heat exchange cavity 17 and the air outlet cavity 18 are arranged sequentially and connected along the width direction of the air outlet shell 102, such as... Figure 4 As shown, the length of the inlet heat exchange chamber 17 in the width direction (i.e., the front-to-back direction, which is also the direction of the depth of the dual-outlet air conditioner) of the outlet housing 102 is denoted as L1, and the length of the outlet chamber 18 in the width direction of the outlet housing 102 is denoted as L2. Where L1+L2≤580mm, it is convenient to suspend the main body of the dual-outlet air conditioner in the ceiling. A second outlet flange 1034 can also be provided at the side air outlet 10. The length L2 of the outlet chamber 18 does not include the length of the second outlet flange 1034 in the outlet direction of the side air outlet 10.

[0029] The air guide mechanism is located in the air outlet housing 102 and is configured to control the opening and closing of the side air outlet 10 and the downwind outlet 13.

[0030] The dual-air outlet air conditioner provided in this application embodiment has an air outlet module 100 with a side air outlet 10 and a bottom air outlet 13. The side air outlet 10 can realize the side air outlet (such as front air outlet) function, so that the airflow can be transported over a long distance; the bottom air outlet 13 can realize the bottom air outlet function, which can solve the problem of the blind spot of air supply below the duct unit, so that the hot air can be grounded in the heating mode, thereby improving the heating effect and improving the user experience.

[0031] Furthermore, the air vent module 100 is detachable and can form a modular assembly structure with the indoor unit body 200. This improves the versatility of the indoor unit body 200 and the air vent module 100, allowing for the sale of multiple products (such as products with and without the air vent module 100). The air vent module 100 can also be assembled with different indoor unit bodies 200 to form different products, easily meeting the diverse needs of different users. In this case, the indoor unit body 200 can be equivalent to the indoor unit of a typical single-outlet air conditioner.

[0032] In some exemplary embodiments, the heat exchanger 4 is vertically arranged. The heat exchanger 4 is a V-shaped heat exchanger (e.g., Figures 4 to 6 (As shown) or an arc-shaped heat exchanger. The projection of a V-shaped heat exchanger onto a vertical or horizontal plane is V-shaped, and the projection of an arc-shaped heat exchanger onto a vertical or horizontal plane is arc-shaped. The air inlet heat exchange chamber 17 includes an air inlet chamber 170 and a heat exchange chamber 172, as shown... Figure 4 and Figure 8 As shown. The fan 3 is located in the air inlet chamber 170, and the heat exchanger 4 is located in the heat exchange chamber 172. The heat exchange chamber 172 is located between the air inlet chamber 170 and the air outlet chamber 18.

[0033] Traditional air conditioner indoor units have only one forward-facing air outlet, and the internal heat exchanger 4 is a tilted, direct-vent type. To meet the required heat exchange area, the heat exchange chamber 172 occupies approximately half the volume of the casing 1, and its width is roughly half the width of the casing 1. Therefore, traditional ducted air conditioners generally do not have a separate air outlet chamber 18 or a guiding mechanism; instead, air is directly discharged through an engineering grille installed on the side wall of the ceiling.

[0034] This solution replaces heat exchanger 4 with a V-shaped or arc-shaped heat exchanger. While meeting the heat exchange area requirements, the size of heat exchanger 4 in the width direction of casing 1 can be greatly reduced. This reduces the size of heat exchange chamber 172 in the width direction of casing 1, providing conditions for the installation of air outlet chamber 18. This allows the air conditioner to add air outlet chamber 18 and air guiding mechanism, thereby optimizing the air outlet effect. Furthermore, the total length of the three chambers in the width direction of air outlet casing 102 is no more than 580mm, ensuring that the depth of casing 1 meets the requirements of conventional suspended ceilings, facilitating the installation of the main body of the air conditioner within the suspended ceiling.

[0035] Since the indoor unit body 200 and the air outlet module 100 form a whole, installed indoors for use, and regulate the indoor temperature by exchanging heat with indoor air, the whole consisting of the indoor unit body 200 and the air outlet module 100 realizes the function of an indoor unit, equivalent to the indoor unit of a split-type air conditioner. In some embodiments, the dual-outlet air conditioner only includes the indoor unit; in other embodiments, the dual-outlet air conditioner also includes an outdoor unit connected to the indoor unit.

[0036] For integrated air conditioners, the main components of the indoor and outdoor units are integrated into the same casing, eliminating the need for separate indoor and outdoor units. In other embodiments, dual-discharge air conditioners also include a compressor, an outdoor heat exchanger, a reversing valve, and other structures; in this case, the dual-discharge air conditioner is an integrated air conditioner.

[0037] Therefore, in this embodiment, the dual-air-discharge air conditioner can be the indoor unit of a split-type air conditioner, such as a wall-mounted indoor unit, a ceiling-mounted indoor unit (such as a ducted air conditioner, a ceiling-mounted air conditioner, etc.), or a split-type air conditioner that includes an indoor unit and an outdoor unit, or an integrated air conditioner.

[0038] The air outlet module 100 can be built into the main body 104 of the housing, or the air outlet module 100 can be located outside the main body 104 of the housing. Both can achieve a detachable connection between the air outlet housing 102 and the main body 104 of the housing, thereby achieving a detachable connection between the air outlet module 100 and the indoor unit main body 200.

[0039] The side air vent 10 can be an air vent inside the housing 1 or an air outlet on the side wall of the housing 1. The air guiding mechanism controls the opening and closing of the side air vent 10. This opening and closing is in a broad sense. As long as the air guiding mechanism can control the air duct (referred to as the side air outlet channel) connected to the side air vent 10 in the air outlet cavity 18 to be open, it is considered that the side air vent 10 is open. As long as the air guiding mechanism can control the side air outlet channel to be blocked, it is considered that the side air vent 10 is closed. It is not required that the air guiding mechanism have a damper that is exactly located at the side air vent 10 and is adapted to the size of the side air vent 10.

[0040] Similarly, the lower air vent 13 can be an air vent inside the housing 1 or an air outlet on the bottom wall of the housing 1. The air guide mechanism controls the opening and closing of the lower air vent 13 in a broad sense. As long as the air guide mechanism can control the air duct (referred to as the side air outlet channel) connected to the lower air vent 13 in the air outlet cavity 18 to be open, it is considered that the lower air vent 13 is open. As long as the air guide mechanism can control the side air outlet channel to be blocked, it is considered that the lower air vent 13 is closed. It is not required that the air guide mechanism have a damper that is exactly located at the lower air vent 13 and is adapted to the size of the lower air vent 13.

[0041] In other embodiments, the air outlet housing 102 and the main housing 104 can also be an integral structure, in which case the air outlet module 100 is a non-detachable module.

[0042] In some exemplary embodiments, the movement range of the air guide mechanism is located within the air outlet housing 102, that is, it will not protrude to the outside of the air outlet housing 102 during movement, so it will not interfere with the structure outside the air outlet housing 102. This can reduce the depth space required by the dual-air outlet air conditioner in the ceiling, and make it easier to suspend the main body of the dual-air outlet air conditioner in the ceiling.

[0043] In some exemplary embodiments, such as Figure 7 and Figure 8 As shown, the air outlet module 100 is located outside the main casing 104, arranged side-by-side and connected to the indoor unit main body 200. The main casing 104 has a first air outlet flange 1042 that communicates with the air inlet heat exchange chamber 17. The air outlet housing 102 has an air inlet flange 1022 that communicates with the air outlet chamber 18, as shown... Figure 12 and Figure 13 As shown. The inlet flange 1022 is fitted onto the first outlet flange 1042 and is sealed to it. The inlet flange 1022 can be on the inside and the first outlet flange 1042 on the outside. Alternatively, the inlet flange 1022 can be on the outside and the first outlet flange 1042 on the inside. In this case, L1 may not include the length of the first outlet flange 1042 of the housing body 104, while L2 may include the length of the inlet flange 1022 of the outlet housing 102. The outlet housing 102 may also have a second outlet flange 1034, and L2 may not include the length of the second outlet flange 1034.

[0044] In this way, the air duct between the indoor unit body 200 and the air outlet module 100 can be sealed together, which helps to prevent air leakage at the connection point, thus helping to prevent condensation and howling.

[0045] The air inlet flange 1022 of the air outlet module 100 and the first air outlet flange 1042 of the housing body 104 can be sealed by circumferential fitting, or a sealing structure (such as a sealing ring) can be added between them to achieve a sealed fit.

[0046] In some exemplary embodiments, such as Figure 10 As shown, the air outlet housing 102 is also provided with a first receiving cavity 1026 and a second receiving cavity 1028, which are located on both sides of the length direction of the air outlet cavity 18.

[0047] The first receiving cavity 1026 can be used, but is not limited to, to receive a driving mechanism or other structures. The driving mechanism is used to drive the movement of the air guide plates (see the movable air guide plate 23, the first air guide plate 21, the second air guide plate 22, etc. in the embodiments below). The driving mechanism may include, but is not limited to, a motor, and may also include a transmission mechanism. Figure 10 As shown, the second receiving cavity 1028 can be used, but is not limited to, for mounting an electronic control mechanism 5 and / or a drive mechanism, wherein the electronic control mechanism 5 is used to control the drive mechanism. The electronic control mechanism 5 can be, but is not limited to, an electronic control board.

[0048] like Figure 9 and Figure 11 As shown, the air outlet module 100 also includes a first cover plate 106 and a second cover plate 108. The first cover plate 106 covers the end of the first receiving cavity 1026 away from the indoor unit body 200 and is detachably connected to the air outlet housing 102. The first cover plate 106 is used to cover the drive mechanism, protecting the drive mechanism and ensuring the integrity of the appearance of the dual-air outlet air conditioner. The second cover plate 108 covers the end of the second receiving cavity 1028 away from the indoor unit body 200 and is detachably connected to the air outlet housing 102. The second cover plate 108 is used to cover the electronic control mechanism 5, protecting the electronic control mechanism 5 and ensuring the integrity of the appearance of the dual-air outlet air conditioner.

[0049] like Figure 10 As shown, the first receiving cavity 1026 is provided with a first connecting part 1030 for detachable connection with the indoor unit body 200, and the second receiving cavity 1028 is provided with a second connecting part 1032 for detachable connection with the indoor unit body 200. The first connecting part 1030 can be, but is not limited to, a fastener connection hole, a snap-fit, a slot, or the like. The second connecting part 1032 can be, but is not limited to, a fastener connection hole, a snap-fit, a slot, or the like.

[0050] When it is necessary to install the air vent module 100 onto the indoor unit body 200, the first cover plate 106 and the second cover plate 108 can be removed, the air vent module 100 can be aligned with the indoor unit body 200, and then the air vent module 100 and the indoor unit body 200 can be fixedly connected together through the first connecting part 1030 and the second connecting part 1032. Then the first cover plate 106 and the second cover plate 108 can be installed.

[0051] The first connecting part 1030 can bypass the drive mechanism, and the second connecting part 1032 can bypass the electronic control mechanism 5, so as to reduce the installation difficulty of the air outlet module 100.

[0052] In some exemplary embodiments, such as Figure 4 As shown, a water receiving tray 19 is also provided inside the air inlet heat exchange chamber 17. The front side wall of the water receiving tray 19 is smoothly connected to the air duct wall of the air outlet chamber 18 through a transition structure. This can reduce air resistance and help increase the air volume.

[0053] like Figure 4 As shown, the front sidewall of the water receiving tray 19 can be configured to extend upwards and slope from back to front, which can play a better role in guiding the flow. The transition structure may include, but is not limited to, the first air outlet flange 1042 of the main body 104 or the air inlet flange 1022 of the air outlet housing 102.

[0054] In some exemplary embodiments, such as Figure 4 As shown, the dimension of the air outlet cavity 18 in the height direction of the air outlet housing 102 is denoted as H, where L2 ≤ H. In other words, the width of the air outlet cavity 18 is not greater than its height. This avoids the air outlet cavity 18 being too large in the width direction of the air outlet housing 102, which would cause the depth of the dual-outlet air conditioner to be too large and affect the installation of the dual-outlet air conditioner. When the air outlet housing 102 is also provided with a lower air outlet flange, the height H of the air outlet cavity 18 may or may not include the dimensions of the lower air outlet flange.

[0055] In some exemplary embodiments, the dual-air outlet air conditioner has a first air outlet mode and a second air outlet mode.

[0056] like Figure 4 As shown, the air conditioner based on dual air outlets is in the first air outlet mode, with the lower air outlet 13 closed and the side air outlet 10 open. Therefore, the first air outlet mode is the side air outlet mode.

[0057] like Figure 6 As shown, the air conditioner based on dual air outlets is in the second air outlet mode, with the lower air outlet 13 open and the side air outlet 10 closed. Therefore, the second air outlet mode is the lower air outlet mode.

[0058] In some exemplary embodiments, the dual-air-discharge air conditioner also has a third air-discharge mode, such as... Figure 5 As shown, the air conditioner based on dual air outlets is in the third air outlet mode, with both the down vent 13 and the side vent 10 open.

[0059] Therefore, the dual-outlet air conditioner has three air outlet modes: side outlet mode (i.e., the first outlet mode), bottom outlet mode (i.e., the second outlet mode), and dual outlet mode (i.e., the third outlet mode). When users need rapid cooling or heating, they can select the second outlet mode, in which the airflow is discharged downwards through the bottom air outlet 13, facilitating a rapid temperature drop or rise in the area below. When users want to avoid direct airflow, they can select the first outlet mode, in which the airflow is discharged laterally through the side air outlet 10, facilitating long-distance airflow and avoiding direct airflow onto the user. When users want uniform cooling or heating throughout the entire area, they can select the third outlet mode, in which the airflow is blown out through both the side air outlet 10 and the bottom air outlet 13, enabling rapid temperature adjustment in the nearby area below and also providing long-distance airflow for rapid temperature adjustment in distant areas.

[0060] In some exemplary embodiments, such as Figure 14 As shown, the air outlet housing 102 has a first reference bisecting plane 1038 and a second reference bisecting plane 1036. The first reference bisecting plane 1038 is perpendicular to the height direction of the air outlet housing 102, and the first reference bisecting plane 1038 bisects the air outlet housing 102 in the height direction (i.e., the distance between the two ends of the first reference bisecting plane 1038 and the air outlet housing 102 in the height direction is equal). Figure 14 As shown. When the air outlet housing 102 is also provided with a lower air outlet flange, the height of the air outlet housing 102 includes the dimensions of the lower air outlet flange.

[0061] The second reference bisecting plane 1036 extends along the height direction of the air outlet housing 102 and is perpendicular to the width direction of the air outlet housing 102. The second reference bisecting plane 1036 bisects the lower air outlet in the width direction of the air outlet housing 102 (i.e., the distance between the two ends of the second reference bisecting plane 1036 and the lower air outlet 13 in the width direction is equal). Figure 14 As shown.

[0062] like Figures 14 to 16 As shown, the air guiding mechanism includes: movable air vane 23.

[0063] The movable air deflector 23 has a rotatable connecting part at one end in the width direction. The rotatable connecting part is located between the side air outlet 10 and the lower air outlet 13. The movable air deflector 23 is configured to rotate relative to the housing 1 between a first position and a second position. The rotatable connecting part may include, but is not limited to, a rotating shaft, which is connected to a drive mechanism.

[0064] Specifically, when the movable air vane 23 rotates to the first position, the side air vent 10 is opened and the down air vent 13 is closed, thus achieving a side air outlet mode. When the movable air vane 23 rotates to the second position, the side air vent 10 is closed and the down air vent 13 is opened, thus achieving a down air outlet mode. When the movable air vane 23 rotates to a third position between the first and second positions, both the side air vent 10 and the down air vent 13 are opened, thus achieving a dual air outlet mode.

[0065] Therefore, this solution can control the opening and closing of two air outlets with a single movable air flap 23, which is simple in structure and helps to reduce production costs.

[0066] In some embodiments, such as Figures 14 to 17 As shown, the rotation axis of the movable air vane 23 is positioned higher than the end of the lower air outlet 13 furthest from the rotating connection, and is located on the side of the second reference bisecting plane 1036 near the side air outlet, but lower than the first reference bisecting plane 1038. Therefore, the movable air vane 23 is in an inclined state when closing the lower air outlet 13, rather than a horizontal state, hence the lower air outlet 13 is an inclined opening. With a consistent width in the horizontal direction, the inclined lower air outlet 13 has a larger area than a horizontally positioned lower air outlet 13, which helps to increase the airflow of the lower air outlet 13.

[0067] In some embodiments, the width of the side vent 10 is equal to the width of the downvent 13. When the downvent 13 and the side vent 10 are controlled to open and close by the same movable air plate 23, the width and ventilation area of ​​the inclined downvent 13 are larger than those of the horizontally arranged downvent 13. Consequently, the width and ventilation area of ​​the side vent 10 are also larger, which is beneficial to increasing the air volume of the side vent 10.

[0068] In other embodiments, the width of the side vent 10 is greater than the width of the downwind vent 13, which helps to increase the air volume when the air is vented from the side and increase the air supply distance, thereby helping to improve the uniformity of indoor temperature.

[0069] The position of the rotating connection part is higher than the end of the downwind vent 13 that is far away from the side vent 10, and the distance between the rotating connection part and the end of the downwind vent 13 that is far away from the side vent 10 is greater than the width of the movable air plate 23. Therefore, the movable air plate 23 cannot completely close the downwind vent 13 on its own.

[0070] Therefore, such as Figure 17 As shown, the end of the downwind vent 13 away from the side vent 10 is also provided with a first fixed air plate 24 protruding towards the rotating connection part. The first fixed air plate 24 is configured to overlap with the movable air plate 23 when the movable air plate 23 is rotated to the first position, so that the downwind vent 13 is closed, which helps to prevent air leakage from the downwind vent 13 in the side air outlet mode.

[0071] This solution achieves the closure of the downwind opening 13 by cooperating with the movable air flap 23 and the first fixed air flap 24, which helps to reduce the width of the movable air flap 23.

[0072] In some embodiments, such as Figure 16 As shown, the air outlet cavity 18 is also provided with a guide wall 1024, which extends inclinedly towards the rotating connection part. When the movable air plate 23 rotates to the second position, it overlaps with the guide wall 1024 to close the side air outlet 10. Figure 14 As shown. In this way, the width of the movable air vane 23 can be smaller than the width of the side air vent 10, which helps to reduce the width of the movable air vane 23, thereby reducing the space required for the movable air vane 23 to rotate, and is conducive to the miniaturization of the dual-outlet air conditioner.

[0073] Among them, the guide wall 1024 is an arc-shaped air duct wall located in the air outlet cavity 18 (such as...). Figure 16 As shown in the figure, a guide wall 1024 is formed on a portion of the inner wall surface of the air outlet cavity 18, and the guide wall 1024 can be integrally formed with the air outlet housing 102.

[0074] Alternatively, the guide wall 1024 can be an arc-shaped air vane located within the air outlet cavity 18; that is, an arc-shaped air vane is installed on the inner side of the air outlet cavity 18 to form the guide wall 1024. One end of the arc-shaped air vane is fixedly connected to the cavity wall of the air outlet cavity 18, while the other end is suspended. The arc-shaped air vane can be separately manufactured and then installed within the air outlet cavity 18, or it can be integrally formed with the air outlet housing 102.

[0075] In some exemplary embodiments, the air outlet housing 102 has a second reference bisecting plane 1036, which extends along the height direction of the air outlet housing 102 and is perpendicular to the width direction of the air outlet housing 102. The second reference bisecting plane 1036 bisects the lower air outlet 13 in the width direction of the air outlet housing 102 (i.e., the distance between the two ends of the second reference bisecting plane 1036 and the lower air outlet 13 in the width direction is equal). Figure 12 and Figure 18 As shown.

[0076] like Figures 4 to 6 , Figures 18 to 27 As shown, the air guiding mechanism includes: a first air guiding plate 21 and a second air guiding plate 22. The first air guiding plate 21 is provided with a first rotating connection part that is rotatably connected to the air outlet housing 102, and the second air guiding plate 22 is provided with a second rotating connection part that is rotatably connected to the air outlet housing 102. The second rotating connection part and the first rotating connection part are located on the same side of the second reference bisecting plane 1036.

[0077] Compared to the scheme that controls the opening and closing of two air vents through a single movable air vane, this scheme controls the opening and closing of two air vents through two rotatable air guide vanes. The rotating connection parts of the two air guide vanes are located on the same side of the second reference bisecting plane 1036, making the distance between the two air guide vanes relatively close. This is beneficial for reducing the rotation radius and rotation range of a single air guide vane, thereby reducing the requirements on the drive mechanism. It also makes it easier for the two air guide vanes to close the side air vent 10 by overlapping each other, thereby reducing the air leakage of the side air vent 10 and reducing the risk of condensation.

[0078] In some embodiments, such as Figures 4 to 6 , Figures 18 to 24 As shown, the side air vent 10 includes a first sub-air vent 11 and a second sub-air vent 12 arranged side by side along the height direction of the casing 1.

[0079] The first air guide plate 21 has a first rotatable connecting part at one end in the width direction. The first rotatable connecting part is located between the first sub-air outlet 11 and the lower air outlet 13, and can rotate relative to the air outlet housing 102, so that the first air guide plate 21 can reciprocate between a first position with the lower air outlet 13 closed and a second position with the first sub-air outlet 11 closed. The second air guide plate 22 is located at the second sub-air outlet 12 and is configured to rotate relative to the air outlet housing 102 to control the opening and closing of the second sub-air outlet 12.

[0080] The side air vent 10 of this design includes two sub-vents, which helps to increase the width of the side air vent 10 and thus improve the air volume when discharging air from the side. Correspondingly, the air guiding mechanism includes two air guide plates, which facilitates the individual guidance of the two sub-vents and helps to optimize the air guiding effect.

[0081] In some examples, such as Figures 4 to 6 , Figures 18 to 21 As shown, the first sub-air vent 11 is located below the second sub-air vent 12, and the second air guide plate 22 is located above the first air guide plate 21.

[0082] In some examples, such as Figures 4 to 6 , Figure 18 and Figure 19 As shown, the second air guide plate 22 is provided with a second rotating connection part connected to the second drive mechanism 62. The orthographic projection of the second rotating connection part and the first rotating connection part on the horizontal plane do not coincide.

[0083] If the projections of the second rotating connecting part and the first rotating connecting part on the horizontal plane do not coincide, then when the side air vent 10 is closed, the plate surface of the first air guide plate 21 facing the inside of the housing 1 and the plate surface of the second air guide plate 22 facing the inside of the housing 1 can be appropriately offset in the horizontal direction. In this way, the upper end of the first air guide plate 21 and the lower end of the second air guide plate 22 can overlap (e.g., Figure 19As shown in the figure, this achieves a sealing effect, which helps reduce air leakage and prevents condensation.

[0084] The first rotating connection may include, but is not limited to, the first rotating shaft 211. The second rotating connection may include, but is not limited to, the second rotating shaft 221. The air vent module 100 also includes a first drive mechanism 61 and a second drive mechanism 62, such as... Figure 10 As shown. The first drive mechanism 61 is connected to the first rotating shaft 211 and is configured to drive the first rotating shaft 211 to rotate. The second drive mechanism 62 is connected to the second rotating shaft 221 and is configured to drive the second rotating shaft 221 to rotate.

[0085] In other embodiments, the orthographic projections of the second rotating connection portion and the first rotating connection portion on the horizontal plane may also coincide.

[0086] In some examples, such as Figures 4 to 6 , Figure 18 and Figure 19 As shown, the second rotating connection part is offset towards the inside of the housing 1 compared to the first rotating connection part.

[0087] Thus, when the side vent 10 is closed, the duct wall formed by the first air guide plate 21 facing the inner side of the casing 1 and the second air guide plate 22 facing the inner side of the casing 1 extends obliquely from top to bottom and outward, as shown in the image. Figure 18 and Figure 19 As shown. Thus, part of the airflow flowing towards the second guide vane 22 continues along the second guide vane 22 towards the first guide vane 21, while the other part is diverted and flows directly towards the downwind outlet 13. Part of the airflow flowing towards the first guide vane 21 continues along the first guide vane 21, while the other part is diverted and flows directly towards the downwind outlet 13. This improves the uniformity of airflow at the downwind outlet 13.

[0088] The relative position of the second rotating connecting part and the second air guide plate 22 is not restricted, and can be located at the end of the width direction of the second air guide plate 22 (e.g., Figures 4 to 6 , Figure 19 (As shown), or it can be located between the two ends in the width direction of the second air guide plate 22, such as Figure 18 As shown.

[0089] In some examples, such as Figure 18 As shown, the first rotating connection part includes a first rotating shaft 211, and a first driving mechanism 61 is connected to the first rotating shaft 211 and configured to drive the first rotating shaft 211 to rotate.

[0090] The first drive mechanism 61 may include a first drive element, which may be, but is not limited to, a motor (such as a stepper motor). The first drive element may be, but is not limited to, mounted on the housing 1. The first drive mechanism 61 may also include a first transmission mechanism, which may be, but is not limited to, a gear transmission mechanism, a rack and pinion transmission mechanism, etc. The first rotating shaft 211 is fixedly connected to the first drive mechanism 61. The first rotating shaft 211 may also be rotatably connected to the housing 1.

[0091] In some examples, such as Figure 21 As shown, the second rotating connection includes a second rotating shaft 221, and the second driving mechanism 62 is connected to the second rotating shaft 221 and configured to drive the second rotating shaft 221 to rotate.

[0092] The second drive mechanism 62 may include a second drive component, which may be, but is not limited to, a motor (such as a stepper motor). The second drive component may be, but is not limited to, mounted on the housing 1. The second drive mechanism 62 may also include a second transmission mechanism, which may be, but is not limited to, a gear transmission mechanism, a rack and pinion transmission mechanism, etc. The second rotating shaft 221 is fixedly connected to the second drive mechanism 62. The second rotating shaft 221 may also be rotatably connected to the housing 1.

[0093] In some examples, the second air guide plate 22 includes a second air guide body 224. A second rotating shaft 221 is connected to one end of the second air guide body 224 along its length. The number of second rotating shafts 221 can be one or two. When there is only one second rotating shaft 221, a shaft hole can be provided at the other end of the second air guide body 224. When there are two second rotating shafts 221, the two shafts 221 are respectively located at both ends of the second air guide body 224 along its length.

[0094] In some examples, the width of the second sub-vent 12 is less than or equal to the width of the first sub-vent 11. This ensures that the widths of the first sub-vent 11 and the downwind vent 13 are not too small, guaranteeing good airflow performance for both downwind and side airflow.

[0095] In some examples, such as Figure 6 , Figure 18 and Figure 19 As shown, the second air guide plate 22 is configured to overlap with the first air guide plate 21 so that the side air vent 10 can be closed. This facilitates rapid cooling and heating. Furthermore, the overlap between the second air guide plate 22 and the first air guide plate 21 reduces air leakage in the down-discharge mode, which helps prevent condensation and whistling.

[0096] In some examples, the second rotating shaft 221 is located near the end (i.e., the lower end) of the first air guide plate 21 in the width direction of the second air guide plate 22, such as... Figure 19 As shown.

[0097] Of course, the second rotating shaft 221 can also be located at the end (i.e., the upper end) of the second air guide plate 22 away from the first air guide plate 21 in the width direction. Figures 4 to 6 (As shown). Alternatively, the second rotating shaft 221 can also be located at the center of the width direction of the second air guide plate 22, and directly connected to the second air guide body 224, as shown. Figure 18 As shown. In Figure 18 In the diagram, the dashed lines indicate other working positions of the first air guide plate 21, and the dotted lines indicate other working positions of the second air guide plate 22.

[0098] In some examples, dual-airflow air conditioners are in the first airflow mode (e.g.) Figure 4 and Figure 18 As shown), the downwind vent 13 is closed, the side vent 10 is opened, the first air guide plate 21 is in the first position to open the first sub-vent 11 and close the downwind vent 13, and the second air guide plate 22 opens the second sub-vent 12.

[0099] Air conditioners with dual air outlets are in the second air outlet mode (e.g.) Figure 6 , Figure 18 and Figure 19 As shown), the downwind vent 13 is opened, the side vent 10 is closed, the first air guide plate 21 is in the second position to close the first sub-vent 11 and open the downwind vent 13 and overlap with the second air guide plate 22, and the second air guide plate 22 closes the second sub-vent 12.

[0100] Air conditioners with dual air outlets are in the third air outlet mode (e.g.) Figure 5 and Figure 18 As shown), the downwind vent 13 and the side vent 10 are both opened, the first air guide plate 21 is located in the third position between the first position and the second position to open the first sub-vent 11 and the downwind vent 13, and the second air guide plate 22 opens the second sub-vent 12.

[0101] In some examples, when a dual-airflow air conditioner switches from a second airflow mode to a first or third airflow mode, the first air guide plate 21 and the second air guide plate 22 rotate in the same direction, such as clockwise (or counterclockwise), which helps to avoid interference between the two air guide plates during rotation. However, the rotation angles of the first air guide plate 21 and the second air guide plate 22 can be the same or different. In some examples, the housing 1 is provided with a first overlapping edge 14 (e.g., Figure 4 (as shown) and the second overlapping edge 15 (as shown) Figure 6 As shown in Figure 4, when the first air guide plate 21 rotates to the first position, it overlaps with the first overlapping edge 14. When the first air guide plate 21 rotates to the second position, it overlaps with the second overlapping edge 15. Figure 6 As shown.

[0102] This helps to improve the closing effect of the first air guide plate 21 on the first sub-air outlet 11 and the downwind outlet 13, thereby helping to prevent condensation and air leakage.

[0103] The first overlapping edge 14 is arranged in a ring structure along the circumference of the downwind opening 13, and the second overlapping edge 15 is arranged in a semi-enclosed structure along the circumference of the first sub-air outlet 11. This helps to improve the closing effect of the first air guide plate 21 on the first sub-air outlet 11 and the downwind opening 13.

[0104] Similarly, the housing 1 can also be provided with a third overlapping edge 16, such as Figure 6 As shown, the third overlapping edge 16 is arranged circumferentially along the second sub-vent 12 to form a semi-enclosed structure. Based on the second guide plate 22 rotating to the position where the second sub-vent 12 is closed, the second guide plate 22 overlaps with the third overlapping edge 16. This improves the closing effect of the second guide plate 22 on the second sub-vent 12, thus helping to prevent condensation and air leakage. When the first guide plate 21 and the second guide plate 22 respectively close the first sub-vent 11 and the second sub-vent 12, the first guide plate 21 and the second guide plate 22 can overlap each other, completely closing the side vent 10, as shown. Figure 6 As shown.

[0105] In other embodiments, such as Figures 20 to 22 As shown, the first sub-vent 11 is located above the second sub-vent 12, and the second air guide plate 22 is located below the first air guide plate 21. The rotation axis of the first air guide plate 21 is positioned higher than the end of the lower air vent 13 furthest from the first rotating connection. Therefore, when the first air guide plate 21 closes the lower air vent 13, it is in an inclined state, not a horizontal state; hence, the lower air vent 13 is an inclined opening. With a consistent width in the horizontal direction, the inclined lower air vent 13 has a larger area than a horizontally positioned lower air vent 13, which helps to increase the airflow of the lower air vent 13.

[0106] The air outlet housing 102 can be provided with a lower air outlet channel. The upper port of the lower air outlet channel is the lower air outlet 13. The lower port of the lower air outlet channel can be set horizontally, so that the appearance structure of the housing 1 is more regular.

[0107] In some examples, the second sub-vent 12 is connected to the first sub-vent 11, which can form an opening to facilitate the processing and shaping of the housing 1.

[0108] In some examples, the second air guide plate 22 has a second rotating connection part at one end near the first sub-air outlet 11, and the second rotating connection part is coaxially arranged with the first rotating connection part, such as... Figures 20 to 22As shown. In this way, when the first air guide plate 21 and the second air guide plate 22 are both supported on the housing 1, they can be supported on the same part of the housing 1 to simplify the structure of the housing 1. They can even use the same drive mechanism to drive the first air guide plate 21 and the second air guide plate 22 to simplify the air conditioner structure.

[0109] In some examples, during the switching from the second air outlet mode to the third air outlet mode in a dual-air outlet air conditioner, the first air guide plate 21 and the second air guide plate 22 rotate in opposite directions. Please refer to the above examples. Figure 20 and Figure 22 As shown, during the process of switching from the second air outlet mode to the third air outlet mode in the dual-air outlet air conditioner, the first air guide plate 21 rotates clockwise toward the inside of the casing 1, and the second air guide plate 22 rotates counterclockwise toward the inside of the casing 1. Therefore, the first air guide plate 21 and the second air guide plate 22 rotate toward each other.

[0110] In this way, the movable space of the first air guide plate 21 and the second air guide plate 22 is located on the same side of their rotation axis, and they can share the movable space, which is beneficial to reducing the depth of the air outlet cavity 18. Furthermore, the first air guide plate 21 and the second air guide plate 22 can be rotated to a position where they just touch. At this time, the first air guide plate 21 and the second air guide plate 22 can divide the internal space of the air outlet cavity 18 into two channels, so that part of the airflow flows along the first air guide plate 21 to the first sub-air outlet 11, and the other part of the airflow flows along the second air guide plate 22 to the second sub-air outlet 12 and the lower air outlet 13.

[0111] In other embodiments, the second rotating connection portion and the first rotating connection portion may also be arranged on different axes, for example, they may be arranged parallel and spaced apart (see reference). Figures 20 to 22 As shown, the second rotating shaft 221 of the second air guide plate 22 can be set at the lower end of the second air guide plate 22; or refer to Figure 19 As shown, simply swap the positions of the upper and lower air guide plates.

[0112] The specific locations of the first and second rotating connecting parts can be reasonably set according to needs. For example, based on the fact that the second rotating connecting part is coaxial with the first rotating connecting part, the first and second rotating connecting parts are located on the side wall of the air outlet cavity 18 away from the heat exchange cavity 172, such as... Figures 20 to 22 As shown.

[0113] Alternatively, the second rotating connecting part can be coaxially arranged with the first rotating connecting part, and both the first and second rotating connecting parts can be located within the air outlet cavity 18, such as... Figure 24 As shown.

[0114] Alternatively, the second rotating connection portion can be arranged parallel to and spaced apart from the first rotating connection portion, with the first rotating connection portion located inside the air outlet cavity 18 and the second rotating connection portion located on the side wall of the air outlet cavity 18 away from the heat exchange cavity 172 (see reference). Figure 19 As shown, simply swap the positions of the upper and lower air guide plates.

[0115] In some examples, such as Figure 23 As shown, the first rotating connecting part includes a first rotating shaft 211, and the second rotating connecting part includes a second rotating shaft 221. At least one of the first rotating shaft 211 and the second rotating shaft 221 is a hollow shaft, so that the first rotating shaft 211 and the second rotating shaft 221 can be nested together. The air vent module 100 also includes a first driving mechanism 61 and a second driving mechanism 62. The first driving mechanism 61 is connected to the first rotating shaft 211 and is configured to drive the first rotating shaft 211 to rotate. The second driving mechanism 62 is connected to the second rotating shaft 221 and is configured to drive the second rotating shaft 221 to rotate.

[0116] In this way, the rotation of the first air guide plate 21 and the second air guide plate 22 is independent of each other, and the rotation direction and rotation amplitude of the first air guide plate 21 and the second air guide plate 22 can be reasonably controlled as needed.

[0117] In some examples, such as Figure 23 As shown, the first air guide plate 21 is also provided with a first support part 212 connected to the first rotating shaft 211, and the second air guide plate 22 is also provided with a second support part 222 connected to the second rotating shaft 221. The first support part 212 and the second support part 222 are staggered along the axial direction of the first rotating shaft 211.

[0118] The hollow shaft may have a notch so that the rotating shaft located inside it can be connected to the structure outside the hollow shaft (such as the first support part 212 / second support part 222, or the housing 1, or the first drive mechanism 61 / second drive mechanism 62).

[0119] The first rotating shaft 211 and the first support part 212 can be a separate assembly structure (i.e., they are processed and formed separately and then assembled together, such as snap-fit ​​connection, fastener connection, adhesive bonding, etc.), and the second rotating shaft 221 and the second support part 222 can be a separate assembly structure (such as snap-fit ​​connection, fastener connection, adhesive bonding, etc.). This facilitates nesting the first rotating shaft 211 and the second rotating shaft 221, and then connecting them to the first support part 212 and the second support part 222 respectively. The first support part 212 and the air guide body of the first air guide plate 21 (i.e., the first air guide body 213) can be an integrated structure or a separate assembly structure. The second support part 222 and the air guide body of the second air guide plate 22 (i.e., the second air guide body 224) can be an integrated structure or a separate assembly structure.

[0120] The first support portion 212 can be a block structure with a shaft hole or a C-shaped groove, and the first rotating shaft 211 passes through the shaft hole or C-shaped groove of the first support portion 212. The second support portion 222 can be a block structure with a shaft hole or a C-shaped groove, and the second rotating shaft 221 passes through the shaft hole or C-shaped groove of the second support portion 222.

[0121] like Figure 23 As shown, there can be multiple first support portions 212, which can be spaced apart along the axial direction of the first rotating shaft 211. There can also be multiple second support portions 222, which can be spaced apart along the axial direction of the second rotating shaft 221. The multiple first support portions 212 and the multiple second support portions 222 can be staggered. Alternatively, the multiple first support portions 212 can be divided into two groups, with the multiple second support portions 222 located between the two groups of first support portions 212. Or, the multiple second support portions 222 can be divided into two groups, with the multiple first support portions 212 located between the two groups of second support portions 222.

[0122] The structures of the first drive mechanism 61 and the second drive mechanism 62 can be referred to the aforementioned embodiments, and will not be repeated here.

[0123] In some examples, the first drive mechanism 61 and the second drive mechanism 62 are spaced apart on both sides of the first sub-air outlet 11 along the axial direction of the first rotating shaft 211. One end of the first rotating shaft 211 is connected to the first drive mechanism 61, and the other end is rotatably connected to the housing 1. One end of the second rotating shaft 221 is connected to the second drive mechanism 62, and the other end is rotatably connected to the housing 1.

[0124] The first rotating shaft 211, at one end connected to the first driving mechanism 61, can protrude beyond the second rotating shaft 221 to be connected to the first driving mechanism 61. The second rotating shaft 221, at one end connected to the second driving mechanism 62, can protrude beyond the first rotating shaft 211 to be connected to the second driving mechanism 62.

[0125] The housing 1 may be provided with a first shaft hole and a second shaft hole, and the two ends of the hollow shaft are respectively inserted into the first shaft hole and the second shaft hole, so as to realize the rotatable connection between the first rotating shaft 211 and the second rotating shaft 221 and the housing 1.

[0126] In some examples, the second air guide plate 22 is positioned at the fourth position after the second sub-air outlet 12 is closed (e.g., Figure 20 and Figure 21 (as shown) and the fifth position of opening the second sub-vent 12 (as shown) Figure 22 (As shown) rotates between positions. Furthermore, from the fourth position to the fifth position, the second air guide plate 22 rotates inward toward the inside of the housing 1, in conjunction with... Figures 20 to 22 It can be known that...

[0127] This avoids the second air guide plate 22 occupying the space outside the casing 1 during rotation, which helps to reduce the depth requirement when the ducted air conditioner is installed in the ceiling. Furthermore, when the second air guide plate 22 rotates to the fifth position, it can also act as a duct wall to guide the airflow, making it easier to guide the airflow to the second sub-air outlet 12.

[0128] Of course, from the fourth position to the fifth position, the second air guide plate 22 can also rotate to the outside of the housing 1.

[0129] In other examples, the first rotating shaft 211 and the second rotating shaft 221 are coaxially arranged, and the first rotating shaft 211 and the second rotating shaft 221 are fixedly connected or in a limiting engagement. For example, one of the first rotating shaft 211 and the second rotating shaft 221 has a non-cylindrical limiting groove, and the other has a non-cylindrical limiting protrusion. The limiting protrusion is inserted into the limiting groove to limit the engagement of the first rotating shaft 211 and the second rotating shaft 221 and allow them to rotate synchronously. Alternatively, the first rotating shaft 211 and the second rotating shaft 221 are fixedly connected together by means of clamps, bushings, fasteners, integral molding, etc., to achieve synchronous rotation.

[0130] The dual-air-discharge air conditioner also includes a drive mechanism, which is connected to the first rotating shaft 211 or the second rotating shaft 221 and is configured to drive the first rotating shaft 211 and the second rotating shaft 221 to rotate synchronously.

[0131] In other words, the first air guide plate 21 and the second air guide plate 22 can also be connected through the same drive mechanism, so the rotation direction (clockwise or counterclockwise) of the first air guide plate 21 and the second air guide plate 22 is the same. When the first air guide plate 21 rotates to the first position to close the lower air outlet 13, the second air guide plate 22 turns outward from the housing 1 to open the second sub-air outlet 12, thereby realizing the side air outlet mode (the first air guide plate 21 has rotated to the first position) and the dual air outlet mode (the first air guide plate 21 has not yet rotated to the first position). When the first air guide plate 21 rotates to the second position to close the first sub-air outlet 11, the second air guide plate 22 rotates inward from the housing 1 to close the second sub-air outlet 12, thereby realizing the lower air outlet mode.

[0132] In some embodiments, the dual-airflow air conditioner is in the first airflow mode (e.g., Figure 21As shown), the downwind vent 13 is closed, and the side vent 10 is opened (the opening range is not limited; for example, only the first sub-vent 11 can be opened, or both the first sub-vent 11 and the second sub-vent 12 can be opened). The first air guide plate 21 is in the first position to open the first sub-vent 11 and close the downwind vent 13. The second air guide plate 22 is in the fourth position to close the second sub-vent 12 (for example, in the case where the first rotating shaft 211 and the second rotating shaft 221 rotate independently) or in the fifth position to open the second sub-vent 12 (for example, in the case where the first rotating shaft 211 and the second rotating shaft 221 rotate synchronously).

[0133] Air conditioners with dual air outlets are in the second air outlet mode (e.g.) Figure 20 As shown), the downwind vent 13 is opened, the side vent 10 is closed, the first air guide plate 21 is in the second position to close the first sub-vent 11 and open the downwind vent 13, and the second air guide plate 22 is in the fourth position to close the second sub-vent 12.

[0134] Air conditioners with dual air outlets are in the third air outlet mode (e.g.) Figure 22 As shown), both the downwind vent 13 and the side vent 10 are opened, and the first air guide plate 21 is located in the third position between the first position and the second position to open the first sub-vent 11 and the downwind vent 13. The second air guide plate 22 is located in the fifth position to open the second sub-vent 12 (for example, in the case where the first rotating shaft 211 and the second rotating shaft 221 rotate independently) or in the fourth position to close the second sub-vent 12 (for example, in the case where the first rotating shaft 211 and the second rotating shaft 221 rotate synchronously).

[0135] In some other embodiments, such as Figures 25 to 27 As shown, the air guiding mechanism also includes a second fixed air vane 25.

[0136] The second fixed air plate 25 is disposed in the air outlet cavity 18 and is located between the side air outlet 10 and the down air outlet 13. It separates the side air outlet channel communicating with the side air outlet 10 and the down air outlet channel communicating with the down air outlet 13 within the air outlet cavity 18.

[0137] The first air guide plate 21 works in conjunction with the side air outlet channel to control the opening and closing of the side air outlet 10.

[0138] The second air guide plate 22 works in conjunction with the lower air outlet channel to control the opening and closing of the lower air outlet 13.

[0139] This design utilizes a second fixed air vane 25 within the air outlet housing 102 to separate a side air outlet channel and a bottom air outlet channel. This allows the width of the first air guide vane 21 to control the opening and closing of the side air outlet function without needing to be substantially the same as the width of the side air outlet 10, and the width of the second air guide vane 22 to control the opening and closing of the bottom air outlet function without needing to be substantially the same as the width of the bottom air outlet 13. In this way, the widths of the side air outlet 10 and the bottom air outlet 13 can be set as needed, facilitating consideration of factors such as air volume, air conditioner size, and aesthetics. Similarly, the widths of the first air guide vane 21 and the second air guide vane 22 can also be set as needed, facilitating consideration of factors such as air outlet mode switching, air conditioner size, and aesthetics.

[0140] In some examples, such as Figures 25 to 27 As shown, the air outlet cavity 18 has an air inlet port 181 on its side wall near the heat exchange cavity 172 (e.g., Figure 25 As shown, when the air outlet housing 102 includes an air inlet flange 1022, the air inlet port 181 can be a downstream port of the air inlet flange 1022. The shape of the air inlet port 181 can be, but is not limited to, rectangular.

[0141] like Figures 25 to 27 As shown, a first rotating connection portion is provided at one end of the first air guide plate 21 in the width direction, and the first rotating connection portion is located on the side wall where the air inlet port 181 is located. In this way, the first air guide plate 21 can rotate within the air outlet cavity 18, and is not easy to extend outside the air outlet cavity 18. This can avoid interference between the first air guide plate 21 and the structure outside the housing 1 or the structure inside the air inlet heat exchange cavity 172, which is beneficial to reducing the size of the air conditioner.

[0142] like Figures 25 to 27 As shown, one end of the second air guide plate 22 in the width direction is provided with a second rotating connection part, which is located on the side wall where the air inlet port 181 is located, and is located below the first air guide plate 21. In this way, the second air guide plate 22 can rotate within the air outlet cavity 18, and is not easy to extend outside the air outlet cavity 18. This can avoid interference between the second air guide plate 22 and the structure outside the casing 1 or the structure inside the air inlet heat exchange cavity 172, which is beneficial to reducing the size of the air conditioner.

[0143] The first rotating connection may include, but is not limited to, the first rotating shaft 211. The second rotating connection may include, but is not limited to, the second rotating shaft 221. The dual-outlet air conditioner also includes a first drive mechanism 61 and a second drive mechanism 62. The first drive mechanism 61 is connected to the first rotating shaft 211 and is configured to drive the first rotating shaft 211 to rotate. The second drive mechanism 62 is connected to the second rotating shaft 221 and is configured to drive the second rotating shaft 221 to rotate. The structures of the first drive mechanism 61 and the second drive mechanism 62 can be referred to the foregoing embodiments and will not be repeated here.

[0144] In some examples, such as Figures 25 to 27As shown, one end of the second fixed air vane 25 is fixedly connected to the housing 1, and the other end extends upward at an angle and is suspended in the air. The second rotating connection part is located at the bottom of the air inlet port 181, and the position of the second rotating connection part is higher than the fixed end of the second fixed air vane 25.

[0145] This reduces the distance between the second rotating connection and the suspended end (upper end) of the second fixed air plate 25, making it easier to use a narrower second air guide plate 22 to block the lower air outlet channel. When the width of the second air guide plate 22 is small, the rotation range of the second air guide plate 22 can be increased, allowing the free end of the second air guide plate 22 to rotate to a position lower than the second rotating connection. This effectively reduces the flow area of ​​the lower air outlet channel, which helps to increase the airflow velocity of the lower air outlet channel and allows the airflow to be blown downwards further.

[0146] In some examples, such as Figures 25 to 27 As shown, the first rotating connection is located at the top of the air inlet port 181. In this way, the air inlet port 181 will not be blocked regardless of the air outlet mode, which helps to increase the air intake volume of the air inlet port 181 and helps to avoid interference between the first air guide plate 21 and the second air guide plate 22.

[0147] In some examples, the first air guide 21 is configured to rotate between a first position and a second position. This is based on the first air guide 21 being in the second position (e.g., ...). Figure 26 As shown), the first air guide plate 21 contacts the second fixed air plate 25 to block the side air outlet channel. This helps to improve the closing effect of the side air outlet channel and is beneficial for preventing condensation and whistling. Based on the first air guide plate 21 being located in the first position (e.g., Figure 25 and Figure 27 As shown), the first air guide plate 21 is separated from the second fixed air plate 25 to open the side air outlet channel. At this time, the first air guide plate 21 can contact the housing 1 (or it can not contact the housing 1) so as to facilitate the positioning of the first air guide plate 21.

[0148] The second air guide plate 22 is configured to rotate between a third position and a fourth position. Based on the second air guide plate 22 being in the fourth position (e.g., ... Figure 25 As shown), the second air guide plate 22 contacts the second fixed air plate 25 to block the lower air outlet channel. This helps to improve the closing effect of the lower air outlet channel and helps to prevent condensation and whistling. Based on the fact that the second air guide plate 22 is located in the third position (e.g., Figure 26 and Figure 27 As shown), the second air guide plate 22 is separated from the second fixed air plate 25 to open the lower air outlet channel. At this time, the second air guide plate 22 can contact the housing 1 (or it can not contact the housing 1) so as to facilitate the positioning of the second air guide plate 22.

[0149] like Figure 25As shown, the air conditioner based on dual air outlets is in the first air outlet mode, with the first air guide plate 21 in the first position and the second air guide plate 22 in the fourth position.

[0150] like Figure 26 As shown, the air conditioner based on dual air outlets is in the second air outlet mode, with the first air guide plate 21 in the second position and the second air guide plate 22 in the third position.

[0151] like Figure 27 As shown, the air conditioner based on dual air outlets is in the third air outlet mode, with the first air guide plate 21 in the first position and the second air guide plate 22 in the third position.

[0152] In some examples, such as Figure 25 As shown, the air conditioner based on dual air outlets is in the first air outlet mode, the second air guide plate 22 overlaps with the second fixed air plate 25, and forms a first air guide surface that guides the airflow into the side air outlet channel.

[0153] The second air guide plate 22 overlaps with the second fixed air plate 25, which can improve the closing effect on the lower air outlet channel and help prevent condensation and whistling. The first air guide curved surface helps to guide the airflow smoothly into the side air outlet channel to reduce airflow loss.

[0154] In some examples, such as Figure 26 As shown, the air conditioner based on dual air outlets is in the second air outlet mode. The first air guide plate 21 overlaps with the second fixed air plate 25, and forms a second air guide surface that guides the airflow into the lower air outlet channel.

[0155] The first air guide plate 21 overlaps with the second fixed air plate 25, which can improve the closing effect of the opposite air outlet channel and help prevent condensation and whistling. The curved surface of the second air guide helps to guide the airflow smoothly into the lower air outlet channel, thereby reducing airflow loss.

[0156] In some examples, such as Figure 27 As shown, a water receiving tray 19 is provided inside the air inlet heat exchange chamber 172, and the water receiving tray 19 is located on the rear side of the second air guide plate 22. The front part of the water receiving tray 19 can be configured to extend upward from back to front to form a guide slope.

[0157] Among them, such as Figure 25 As shown, the air conditioner based on dual air outlets is in the first air outlet mode, the second air guide plate 22 overlaps with the front of the water receiving tray 19, and forms a third air guide surface to guide the airflow into the side air outlet channel.

[0158] The second air guide plate 22 overlaps with the front of the water tray 19, which can prevent air leakage or vortex formation caused by gaps between the water tray 19 and the second air guide plate 22 in the first air outlet mode, thus reducing airflow loss. The third air guide curved surface helps to guide the airflow smoothly into the side air outlet channel, thereby reducing airflow loss.

[0159] In some examples, such as Figure 26 and Figure 27 As shown, the air conditioner based on dual air outlets is in the second air outlet mode or the third air outlet mode. The second air guide plate 22 overlaps with the front of the water receiving tray 19 and forms a fourth air guide surface to guide the airflow into the lower air outlet channel.

[0160] The second air guide plate 22 overlaps with the front of the water tray 19, which can prevent air leakage or turbulence from forming between the water tray 19 and the second air guide plate 22 in the second or third air outlet modes, thus reducing airflow loss. The fourth air guide curved surface helps to guide the airflow smoothly into the lower air outlet channel, thereby reducing airflow loss.

[0161] In some examples, such as Figure 26 As shown, based on the second air guide plate 22 being located in the third position, along the airflow direction of the lower air outlet channel, the distance between the second air guide plate 22 and the second fixed air plate 25 gradually decreases. This can increase the airflow speed of the lower air outlet channel, allowing the airflow to be blown further, which is beneficial for achieving rapid cooling in cooling mode and for allowing hot air to land quickly in heating mode.

[0162] In some examples, such as Figure 25 As shown, based on the first air guide plate 21 being located in the first position, the distance between the first air guide plate 21 and the second fixed air plate 25 gradually increases along the airflow direction of the side air outlet channel. This is beneficial for improving the uniformity of airflow from the side air outlet 10 and also for smoother airflow output to reduce airflow noise.

[0163] In some examples, combined Figures 25 to 27 It can be seen that the first and second positions are located on one side of the thickness direction of the second fixed air plate 25, and the third and fourth positions are located on the other side of the thickness direction of the second fixed air plate 25. This is to avoid interference between the first air guide plate 21 and the second air guide plate 22.

[0164] In some examples, the first air guide plate 21 is an arc-shaped air guide plate. Based on the dual-air outlet air conditioner being in the second air outlet mode, the concave surface of the first air guide plate 21 faces away from the second air guide plate 22, such as... Figure 26 As shown.

[0165] In this way, part of the airflow blowing onto the first guide vane 21 can flow along the convex surface of the first guide vane 21 to the second fixed wind vane 25, while the other part can be blown directly downwind vent 13. Since the convex surface easily breaks the wall adhesion effect of the wind, it reduces the phenomenon of the wind continuing to advance along the convex surface of the first guide vane 21, and avoids the airflow on the first guide vane 21 from concentrating at the end and changing direction. This can accelerate the airflow change and help improve the uniformity of the airflow at the downwind vent 13.

[0166] In some examples, the second fixed air vane 25 is an arc-shaped air vane. Based on the dual-air outlet air conditioner being in the second air outlet mode, the convex surface of the second fixed air vane 25 faces away from the second air guide plate 22, such as... Figure 26 As shown.

[0167] In this way, part of the airflow blowing onto the second fixed air vane 25 can flow down the air outlet channel along the concave surface of the second fixed air vane 25. The concave surface can enhance the wall adhesion effect of the airflow, making it easier to guide the airflow blowing onto the second fixed air vane 25 to smoothly turn and flow downwind outlet 13, thus helping to reduce airflow loss.

[0168] In some examples, such as Figure 27 As shown, the second fixed air vane 25 is provided with a stop portion 251. The stop portion 251 is configured to engage with the second air guide vane 22 when the second air guide vane 22 rotates to the fourth position, thereby preventing the second air guide vane 22 from continuing to rotate. This limits the rotation range of the second air guide vane 22, preventing excessive rotation that could cause interference with the first air guide vane 21. The stop portion 251 can be, but is not limited to, a rib, a protrusion, a column, or other structural forms.

[0169] In some exemplary embodiments, 0.1 ≤ L2 / L1 ≤ 0.5, such as 0.1, 0.2, 0.3, 0.4, 0.5, etc. If L2 is too small, the downwind vent 13 will be too small, causing the air velocity to increase sharply when the air in the outlet cavity 18 enters the downwind vent 13, resulting in high noise levels and condensation problems. If L1 is too small, the space in the inlet heat exchange cavity will be too small, resulting in a fan 3 that is too small and cannot meet the airflow requirements (for example, the unit size reaches the dimensions of a 1.5 horsepower unit, but the performance cannot reach that of a 1.5 horsepower unit). After research and testing, limiting L2 / L1 to the above range can balance the noise and condensation problems when the air is vented downwards, while still meeting the airflow requirements of the unit. Of course, L2 / L1 is not limited to the above range and can be adjusted as needed.

[0170] In some exemplary embodiments, 40mm ≤ L2 ≤ 120mm, such as 40mm, 60mm, 80mm, 100mm, 120mm, etc., which can take into account both the installation requirements of the air conditioning air guide mechanism and the overall size requirements of the housing 1. Of course, L2 is not limited to the above range and can be adjusted as needed.
