[0041] Detailed Explanation

[0042] The principles and features of the embodiments of this application are described below with reference to the accompanying drawings. The examples given are only used to explain the embodiments of this application and are not intended to limit the scope of this application.

[0043] Research has found that in air conditioners with multiple air outlets, condensation and dripping are prone to occur when some air vents are closed in the air guide vane assembly. This is because a gap exists between the circumferential end of the closed air guide vane assembly and the wall of the closed air vent. Therefore, the air guide vane assembly cannot completely close the corresponding air vent when closed. Thus, during air conditioner use, when some air guide vanes are closed, some airflow passes through the gaps, failing to effectively isolate the hot and cold air on both sides of the closed air guide vane assembly. When the air conditioner's outlet temperature is low, and the indoor temperature is high and humidity is high, the encounter of hot and cold air easily leads to condensation on the air guide vane assembly, causing dripping.

[0044] Therefore, as shown in Figures 1 to 19, an embodiment of this application provides an air conditioner, including: a housing 1 and an air guide mechanism 2.

[0045] As shown in Figure 3, the housing 1 is provided with an air duct 14 and multiple air outlets (such as the first air outlet 151 and the second air outlet 152 described below). Each air outlet is configured to communicate with the air duct 14 to form an air outlet channel. The air outlet can be the air outlet of an air conditioner or an opening located upstream of the air outlet inside the air conditioner. As shown in Figure 11, an indoor heat exchanger 3 and a fan 4 can be installed inside the air duct 14. When the fan 4 rotates, indoor air enters the air duct 14, exchanges heat with the indoor heat exchanger 3, and is then discharged into the indoor space through the air outlet channel, thus regulating the temperature of the indoor air.

[0046] The air guiding mechanism 2 includes an air guiding plate assembly movably connected to the housing 1. The air guiding plate assembly is configured to control the opening and closing of multiple air vents to provide multiple airflow modes for the air conditioner. Furthermore, the air guiding plate assembly is configured to engage with the housing 1 when at least some of the air vents are closed to seal the closed vents. The air guiding mechanism 2 may also include a drive mechanism (not shown) connected to the air guiding plate assembly, the drive mechanism being configured to drive the air guiding plate assembly to move relative to the housing 1.

[0047] The air conditioner provided in this application embodiment, by setting multiple air vents and air guide plate assemblies that cooperate with the multiple air vents, enables the air conditioner to have multiple air outlet modes, which helps to meet the different air outlet needs of users, thereby improving the user experience. Furthermore, the air guide plate assembly mainly functions as an air damper. When at least some air vents are closed, the air guide plate assembly can overlap with the housing 1, allowing the corresponding air vents to be completely closed, thus achieving a seal between the air guide plate assembly and the air vent. This effectively isolates the hot and cold air on both sides of the air guide plate assembly in the closed state, thereby preventing condensation and dripping water from forming on the closed air guide plate assembly, and also preventing air leakage and whistling from occurring at the closed air vents, further improving the user experience.

[0048] In this embodiment of the application, the air conditioner can be the indoor unit of a split air conditioner, such as a duct-type indoor unit or a wall-mounted indoor unit, or it can be a split air conditioner unit including an indoor unit and an outdoor unit, or it can be an integrated air conditioner.

[0049] In some exemplary embodiments, the air guiding mechanism 2 includes an air guiding plate (such as the first air guiding plate 21 and the second air guiding plate 22 described below), as shown in Figures 1 and 2. One end of the air guiding plate in the width direction is provided with a rotating part 231 (such as the first rotating part 211 and the second rotating part 221 described below), and the circumferential end of the air guiding plate is provided with a sealing edge 25, as shown in Figure 2. The sealing edge 25 is configured to overlap and seal with the overlapping edge of the circumferential outer side of the air outlet, so that the air guiding plate closes and seals the air outlet.

[0050] In some embodiments, as shown in Figures 1 and 2, the air guide plate includes an air guide plate body 23 and an insulation layer 24. The insulation layer 24 is disposed on one side of the air guide plate body 23 in the thickness direction and is connected to the air guide plate body 23. At least one of the air guide plate body 23 and the insulation layer 24 is provided with a sealing edge 25.

[0051] The air guide plate is configured as a double-layer structure comprising the air guide plate body 23 and the insulation layer 24. The insulation layer 24 provides good heat insulation, reducing heat transfer between the two sides of the air guide plate. This helps reduce the temperature difference between the outer surface of the air guide plate and the outside air, thus reducing the risk of condensation and dripping. Therefore, this design effectively isolates heat transfer between the two sides of the air guide plate, preventing condensation from forming on the air guide plate assembly.

[0052] In some exemplary embodiments, the housing 1 is provided with a plurality of overlapping edges (such as the first to eighth overlapping edges described below), and each air outlet is provided with an overlapping edge on its circumferential outer side. The overlapping edges are configured to overlap and seal with the air guide plate assembly so that the air guide plate assembly seals the closed air outlet.

[0053] Conventional air deflector assemblies are located inside the air vent, and a gap needs to be left between them and the vent wall to avoid interference during the rotation of the air deflector assembly. Therefore, the air deflector assembly cannot completely close the air vent when closed.

[0054] In the air conditioner provided in this application embodiment, the circumferential end of the air guide plate is not inside the air vent, but is located on the circumferential outside of the air vent (for example, the position of the air guide plate can be moved from inside the air vent to the upstream or downstream side of the air vent). Therefore, when the air vent is closed, the circumferential end of the air guide plate assembly is located on the outside of the corresponding air vent, and can overlap and seal with the overlapping edge around the corresponding air vent to ensure that the air vent is completely closed and sealed.

[0055] The sealing edge 25 can be a prismatic structure (for line contact) or a planar structure (for surface contact); the overlapping edge can be a prismatic structure (for line contact) or a planar structure (for surface contact), as long as it can achieve overlapping sealing.

[0056] Furthermore, the sealing edge 25 and the overlapping edge can be in hard contact, meaning that both the sealing edge 25 and the overlapping edge are rigid structures (such as plastic or metal structures), and a seal is formed through the overlap of these rigid structures. Alternatively, the sealing edge 25 and the overlapping edge can be in soft contact, meaning that at least one of the sealing edge 25 and the overlapping edge is a soft structure (such as silicone, rubber, or other soft sealing strips, or insulation cotton), and a seal is formed through the overlap of these soft structures or the overlap of a soft structure with a rigid structure.

[0057] Therefore, in this embodiment, the overlap sealing (e.g., the overlap sealing between the air guide plate assembly and the housing, and the overlap sealing between the sealing edge 25 and the overlap edge) mainly emphasizes that the two overlapping parts achieve contact through overlap to eliminate the reserved gap and avoid air leakage at the gap, thereby achieving a seal between the two parts. As for the sealing effect, it is related to factors such as the material and contact area of ​​the two overlapping parts. For example, the overlap sealing effect between a soft structure and a hard structure is generally better than that between hard structures; the overlap sealing effect achieved by surface contact is generally better than that achieved by line contact. Therefore, in this embodiment, the sealing effect achieved by the overlap sealing does not necessarily mean that it must be airtight in the strict sense. It can be airtight, or there may be a small amount of air leakage, but the amount of air leakage is less than that of the conventional scheme with reserved gaps.

[0058] In some exemplary embodiments, the air guide plate body 23 is an injection molded part, which facilitates the reasonable setting of the shape of the air guide plate body 23 according to requirements. The insulation layer 24 can be a foam part.

[0059] In some exemplary embodiments, the insulation layer 24 and the air guide plate body 23 are configured as an integral structure. The integral structure has high connection strength, is not easy to separate, and has a good fit, which is beneficial to improving the insulation and anti-condensation effect and extending the service life of the air guide plate.

[0060] For example, during the production process, the air guide plate body 23 is first injection molded and then placed into the mold of the insulation layer 24. The liquid insulation layer 24 material is injected into the mold. After it is cured and formed, the insulation layer 24 and the air guide plate body 23 form an integrated structure.

[0061] Of course, the air guide plate body 23 and the insulation layer 24 can also be a separate assembly structure.

[0062] In some exemplary embodiments, as shown in Figures 1 and 2, a rotating part 231 is disposed on the air guide plate body 23, and the rotating part 231 is provided with a filling groove 232. The filling groove 232 has an opening facing the other end of the air guide plate body 23, and one end of the insulation layer 24 is embedded in the filling groove 232. This helps to increase the connection area between the insulation layer 24 and the air guide plate body 23, thereby further improving the connection strength between the insulation layer 24 and the air guide plate body 23.

[0063] In some exemplary embodiments, the cross-sectional outline of the filling groove 232 is set to an arc shape, and the width of the opening is less than or equal to the diameter of the filling groove 232. In this way, one end of the insulation layer 24 in the width direction will be confined within the filling groove 232 and will not easily come out from the opening of the filling groove 232, thereby further improving the connection strength between the insulation layer 24 and the air guide plate body 23.

[0064] The cross-sectional outline of the filling groove 232 refers to the outline of the cross-section perpendicular to the length direction of the air guide plate.

[0065] In some exemplary embodiments, as shown in FIG23, the filling groove 232 includes a plurality of sub-grooves 2321 spaced apart along the length direction of the rotating part 231, and a clearance notch 2314 is formed between adjacent sub-grooves 2321, and the support shaft is located within the clearance notch 2314.

[0066] As shown in Figure 23, the two ends of the clearance notch 2314 can be closed, and the support shaft is connected to the end faces of the two ends of the clearance notch 2314. In this way, the sub-slot 2321 is not connected to the clearance notch 2314, so the insulation layer 24 will not interfere with the support shaft, and it is also convenient for the material of the insulation layer 24 to flow into the sub-slot 2321 during the production process, so that the insulation layer 24 can be integrally formed with the air guide plate body 23.

[0067] In some embodiments, as shown in FIG23, the air guide plate body 23 is further provided with a partition baffle 233. The partition baffle 233 is located on the side of the rotating part 221 near the insulation layer 24 and encloses a space (e.g., a roughly U-shaped space) communicating with the clearance notch 2314. This can effectively separate the support shaft and the insulation layer 24, making it easier for the material of the insulation layer 24 to flow into the sub-groove 2321 during the production process, without entering the clearance notch 2314 and contacting the support shaft.

[0068] In some exemplary embodiments, as shown in FIG23, the outer wall of the rotating part 231 includes a second arc surface 2317, the diameter of which is greater than the thickness of the air guide plate body 23.

[0069] In conventional air guide plates, the diameter of the rotating parts 231 at both ends along the length is usually roughly the same as the thickness of the air guide plate body 23, making them relatively thin and easy to detach. However, in this design, the rotating parts 231 are relatively thicker. This is partly to achieve multi-point support connection with the support carrier to prevent the air guide plate from detaching, and partly to facilitate the setting of the filling groove 232, so as to achieve a better sealing effect using the insulation layer 24.

[0070] In some exemplary embodiments, the insulation layer 24 is positioned at both ends in the width direction of the portion outside the filling groove 232, and is configured to smoothly connect with both ends in the width direction of the air guide plate body 23. This results in smooth surfaces at both ends in the width direction of the air guide plate as a whole, which helps reduce wind resistance.

[0071] In some embodiments, the end of the air guide plate away from the rotating part 231 is provided with an air guide slope, which facilitates the airflow to flow along the air guide plate to reduce wind resistance.

[0072] In some exemplary embodiments, as shown in FIG1, the two ends of the air guide plate body 23 in the length direction are provided with flanges, which helps to prevent the material of the insulation layer 22 from flowing out to both sides during the production process and facilitates processing and forming; it can also increase the contact area between the insulation layer 22 and the air guide plate body 23, thereby helping to improve the connection strength.

[0073] In some exemplary embodiments, as shown in FIG1, the surface of the air guide plate body 23 facing the insulation layer 22 is provided with reinforcing ribs, which is beneficial to improving the strength of the air guide plate body 23 and increasing the contact area between the insulation layer 22 and the air guide plate body 23, thereby improving the connection strength.

[0074] In some exemplary embodiments, as shown in FIG1, the two ends of the rotating part 231 are respectively provided with a first connecting part 2311 and a second connecting part 2312. The first connecting part 2311 is configured to be connected to the driving mechanism, and the second connecting part 2312 is configured to be rotatably connected to the support carrier.

[0075] The drive mechanism includes a drive component, and the first connecting part 2311 can be connected to the drive component. The drive component can be, but is not limited to, a stepper motor. The support carrier can be, but is not limited to, the housing 1 of the air conditioner.

[0076] In some exemplary embodiments, as shown in FIG1, the rotating part 231 is further provided with at least one third connecting part 2313, the third connecting part 2313 being located between the first connecting part 2311 and the second connecting part 2312, and the third connecting part 2313 being configured to be rotatably connected to the support carrier.

[0077] The rotating part 231 of the air guide plate is moved to one end in the width direction of the air guide plate. In addition to the first connecting part 2311 and the second connecting part 2312 respectively provided at both ends in the length direction of the rotating part 231, at least one third connecting part 2313 is added. The first connecting part 2311 is connected to the drive mechanism, and the second connecting part 2312 can be connected to the support carrier to ensure that the air guide plate can be stably supported and rotated under the drive of the drive mechanism. Furthermore, since the rotating part 231 of the air guide plate is moved to one end in the width direction of the air guide plate, it does not affect the structure and function of the main body of the air guide plate, and is adjacent to the support carrier, allowing the rotating part 231 to also be provided with at least one third connecting part 2313. The third connecting part 2313 can also be rotatably connected to the support carrier, realizing multi-point support connection between the air guide plate and the support carrier. This helps prevent the rotating part 231 of the air guide plate from deviating from the set rotation axis and detaching from the support carrier due to bending, deformation, interference, etc., thus playing a good limiting and anti-detachment role and improving the reliability of the air guide plate.

[0078] As shown in Figure 1, there can be multiple third connecting parts 2313, which are spaced apart along the length of the air guide plate. In one example, there are two third connecting parts 2313, which are equally spaced along the length of the air guide plate.

[0079] In some exemplary embodiments, as shown in Figures 1 and 2, the rotating part 231 is configured as a columnar structure extending along the length direction of the air guide plate. The first connecting part 2311 includes a rotating shaft or a shaft hole. The second connecting part 2312 includes a shaft hole or a rotating shaft. The third connecting part 2313 includes a support shaft (as shown in Figures 1 and 2).

[0080] When the first connecting part 2311 includes a rotating shaft, the output shaft of the drive member can be provided with a shaft hole; when the first connecting part 2311 includes a shaft hole, the output shaft of the drive member can be provided with a rotating shaft. Thus, the drive member and the first connecting part 2311 can achieve shaft hole fit, such as a fit between a non-circular shaft and a non-circular hole or an interference fit between a circular shaft and a circular hole, to ensure that the drive member can drive the air guide plate to rotate.

[0081] When the second connecting part 2312 includes a rotating shaft, the support carrier can be provided with a shaft hole; when the second connecting part 2312 includes a shaft hole, the support carrier can be provided with a rotating shaft. Thus, the support carrier and the second connecting part 2312 can achieve a shaft hole fit, such as a clearance fit between a circular shaft and a circular hole, to ensure that the air guide plate can rotate relative to the support carrier.

[0082] When the third connecting part 2313 includes a support shaft, the support carrier is provided with a support hole. The support hole can be provided with a notch that opens towards the air guide plate, so that the support shaft can be inserted into the support hole through the notch and can rotate relative to the support hole.

[0083] In some exemplary embodiments, as shown in FIG1, the rotating part 231 is provided with a clearance notch 2314, and the support shaft is located within the clearance notch 2314. In this way, the diameter of the support shaft is smaller than the diameter of the rotating part 231 and is concentrically arranged with the rotating part 231. While providing support, it can reduce the contact area between the support shaft and the support carrier, thereby reducing frictional resistance.

[0084] In some exemplary embodiments, as shown in FIG23, the sidewall of the support shaft includes a clearance section 2315 and a first arcuate surface 2316 connected circumferentially along the support shaft. The number of clearance sections 2315 can be one or two.

[0085] In other words, the support shaft is not a complete cylinder, but rather a cylinder that has been sectioned along its axial direction to obtain an avoidance section 2315. Therefore, the cross-section of the support shaft is approximately D-shaped (there is only one avoidance section 2315) or racetrack-like (there are two avoidance sections 2315). The avoidance section 2315 reduces the cross-sectional area of ​​the support shaft, facilitating its smooth and rapid entry into the support hole 1303, thus reducing the difficulty of installing the air guide plate. The first arc surface 2316 is adapted to the support hole 1303, facilitating smooth relative rotation.

[0086] In some exemplary embodiments, as shown in FIG3, the plurality of air vents include a first air vent 151 and a second air vent 152, wherein the air outlet directions of the first air vent 151 and the second air vent 152 are different. The first air vent 151 is configured to connect with the air duct 14 to form a first air outlet channel, and the second air vent 152 is configured to connect with the air duct 14 to form a second air outlet channel. In other words, when the first air vent 151 is connected to the air duct 14, the air outlet channel formed by the connection between the two is the first air outlet channel. When the second air vent 152 is connected to the air duct 14, the air outlet channel formed by the connection between the two is the second air outlet channel.

[0087] As shown in Figure 3, the air guide plate assembly includes a first air guide plate 21 and a second air guide plate 22 located inside the housing 1 and movably connected to the housing 1. The first air guide plate 21 and the second air guide plate 22 cooperate to control the opening and closing of the first air outlet 151 and the second air outlet 152, so that the air conditioner has: a first air outlet mode in which the first air outlet channel is open and the second air outlet channel is closed (as shown in Figures 7, 15 and 16), a second air outlet mode in which the first air outlet channel is closed and the second air outlet channel is open (as shown in Figures 3, 17 and 18), and a third air outlet mode in which both the first air outlet channel and the second air outlet channel are open (as shown in Figure 10).

[0088] In this way, the air conditioner has three air outlet modes, allowing users to choose the appropriate mode according to their needs. Furthermore, compared to solutions with more air vents and more air deflectors, this solution has a relatively simple structure, which helps reduce production costs.

[0089] For example, if the first air vent 151 can be a downdraft vent, discharging air downwards; and the second air vent 152 can be a side vent, discharging air horizontally, then the first air outlet mode is a downdraft mode, the second air outlet mode is a side air outlet mode, and the third air outlet mode is a dual air outlet mode. When users need rapid cooling or heating, they can select the first air outlet mode, in which case the airflow is discharged downwards through the first air outlet channel, as shown in Figures 7, 15, and 16, facilitating a rapid temperature decrease or increase in the area below. When users want to avoid direct airflow, they can select the second air outlet mode, in which case the airflow is discharged laterally through the second air outlet channel, as shown in Figures 3, 17, and 18, facilitating long-distance airflow and avoiding direct airflow to the user. When users want uniform cooling or heating throughout the entire area, they can select the third air outlet mode, in which case the airflow is blown out through both the first and second air outlet channels, as shown in Figure 10, enabling rapid temperature adjustment in the nearby area below and also providing long-distance airflow for rapid temperature adjustment in distant areas.

[0090] Of course, the number of air vents is not limited to two, the number of air deflectors is not limited to two, and the number of air outlet modes is not limited to three; the quantities can be adjusted according to needs.

[0091] In some exemplary embodiments, as shown in FIG3, the second air outlet 152 includes a first sub-air outlet 1521 and a second sub-air outlet 1522 that are interconnected, and the second sub-air outlet 1522 is located between the first air outlet 151 and the first sub-air outlet 1521.

[0092] As shown in Figures 13 and 14, the first air guide plate 21 is rotatably connected to the housing 1 and is configured to rotate relative to the housing 1 between a first position where the first air vent 151 is closed and the second sub-air vent 1522 is open, a second position where the first air vent 151 and the second sub-air vent 1522 are open, and a third position where the first air vent 151 is open and the second sub-air vent 1522 is closed.

[0093] As shown in Figures 13 and 14, the second air guide plate 22 is rotatably connected to the housing 1 and is configured to rotate relative to the housing 1 between the fourth position where the first sub-air vent 1521 is closed and the fifth position where the first sub-air vent 1521 is open.

[0094] When the first air guide plate 21 is in the third position and the second air guide plate 22 is in the fourth position, the first air outlet 151 is open and the second air outlet 152 is closed, and the air conditioner is in the first air outlet mode, as shown in Figure 7.

[0095] When the first air guide plate 21 is in the first position and the second air guide plate 22 is in the fifth position, the first air outlet 151 is closed and the second air outlet 152 is open, and the air conditioner is in the second air outlet mode, as shown in Figure 3.

[0096] When the first air guide plate 21 is in the second position and the second air guide plate 22 is in the fifth position, the first air vent 151 opens and the second air vent 152 opens, and the air conditioner is in the third air outlet mode, as shown in Figure 10.

[0097] In other words, the first air guide plate 21 is used to control the opening and closing of the first air vent 151 and the second sub-air vent 1522 (a part of the second air vent 152). The second air guide plate 22 is used to control the opening and closing of the first sub-air vent 1521 (the other part of the second air vent 152). Therefore, the first air guide plate 21 and the second air guide plate 22 jointly control the opening and closing of the second air vent 152. In this way, the widths of the first air vent 151 and the second air vent 152 can be set to different sizes, and the widths of the first air guide plate 21 and the second air guide plate 22 will not be too large, which is beneficial to optimizing the structural layout of the air conditioner and reducing its size.

[0098] Of course, the first air guide plate 21 and the second air guide plate 22 can also control the opening and closing of the first air outlet 151 and the second air outlet 152 respectively. Alternatively, the second air guide plate 22 can be omitted, and the first air guide plate 21 can control the opening and closing of the first air outlet 151 and the second air outlet 152. Alternatively, the first air outlet 151 can also be controlled by both air guide plates.

[0099] In some exemplary embodiments, as shown in Figures 3 to 6, based on the first air guide plate 21 being located in a first position, the circumferential end of the first air guide plate 21 is located on the circumferential outer side of the first air outlet 151 and overlaps and seals with the housing 1 to seal the first air outlet 151.

[0100] As shown in Figures 7 to 9, based on the first air guide plate 21 being located in the third position, the circumferential end of the first air guide plate 21 is located on the circumferential outer side of the second sub-air outlet 1522 and overlaps and seals with the housing 1 and the second air guide plate 22 to seal the second sub-air outlet 1522.

[0101] As shown in Figures 7 to 9, based on the fact that the second air guide plate 22 is located in the fourth position, the circumferential end of the second air guide plate 22 is located on the circumferential outside of the first sub-air outlet 1521 and overlaps and seals with the housing 1 and the first air guide plate 21 to seal the first sub-air outlet 1521.

[0102] In this way, in the first air outlet mode, the first air guide plate 21 and the second air guide plate 22 can completely seal the second air outlet 152, effectively isolating the hot and cold air on both sides of the first air guide plate 21 and the second air guide plate 22 in the closed state, thereby preventing condensation from forming on the first air guide plate 21 and the second air guide plate 22.

[0103] In the second air outlet mode, the first air guide plate 21 can completely seal the first air outlet 151, effectively isolating the hot and cold air on both sides of the first air guide plate 21, thereby preventing condensation from forming on the first air guide plate 21 when it is in the closed state.

[0104] In some exemplary embodiments, as shown in FIG4, one end of the first air guide plate 21 in the width direction is provided with a first rotating part 211 rotatably connected to the housing 1, and the first rotating part 211 is located between the first air outlet 151 and the second sub-air outlet 1522. The second air guide plate 22 in the width direction is provided with a second rotating part 221 rotatably connected to the housing 1 between its ends or both ends.

[0105] In other words, as shown in Figure 4, the rotating part 231 of the first air guide plate 21 is located at one end of the width direction of the first air guide plate 21, which facilitates the rotation of the first air guide plate 21 between the first air outlet 151 and the second sub-air outlet 1522. When the first air outlet 151 is closed by rotation, the second sub-air outlet 1522 is opened, and the first air guide plate 21 is in the first position; when the second sub-air outlet 1522 is closed by rotation, the first air outlet 151 is opened, and the first air guide plate 21 is in the third position; when rotated to between the first air outlet 151 and the second sub-air outlet 1522, both the first air outlet 151 and the second sub-air outlet 1522 are open, and the first air guide plate 21 is in the second position. The opening angle of the first air guide plate 21 when it is in the second position can be reasonably determined according to the positions of the first air outlet 151 and the second sub-air outlet 1522, so that the airflow can flow smoothly along the two surfaces of the first air guide plate 21 to the first air outlet 151 and the second sub-air outlet 1522 respectively, thereby reducing the wind resistance generated by the first air guide plate 21.

[0106] The position of the rotating part 231 of the second air guide plate 22 is not restricted. It can be set at one end of the width direction of the second air guide plate 22 (as shown in Figure 7) or between the two ends of the width direction of the second air guide plate 22.

[0107] In some exemplary embodiments, the driving mechanism includes a first driving member and a second driving member. The first driving member is connected to one end of the first rotating part 211 and is configured to drive the first air guide plate 21 to rotate. The second driving member is connected to one end of the second rotating part 221 and is configured to drive the second air guide plate 22 to rotate. The other end of the first rotating part 211 is rotatably connected to the housing 1. The other end of the second rotating part 221 is rotatably connected to the housing 1.

[0108] The connection between the first rotating part 211 and the first driving member can be a shaft-hole fit, such as an interference fit between a non-circular shaft and a non-circular hole or an interference fit between a circular shaft and a circular hole. The connection between the first rotating part 211 and the housing 1 can also be a shaft-hole fit, such as a clearance fit between a circular shaft and a circular hole. Similarly, the connection between the second rotating part 221 and the second driving member can also be a shaft-hole fit, such as an interference fit between a non-circular shaft and a non-circular hole or an interference fit between a circular shaft and a circular hole. The connection between the second rotating part 221 and the housing 1 can also be a shaft-hole fit, such as a clearance fit between a circular shaft and a circular hole.

[0109] The first driving component can be, but is not limited to, a stepper motor. The second driving component can be, but is not limited to, a stepper motor. The first and second driving components can be installed inside the housing 1.

[0110] In some exemplary embodiments, as shown in Figures 3 and 7, the housing 1 includes an outer shell 11, a water receiving tray 12 connected to the outer shell 11, and an air guide support 13 connected to the outer shell 11 and the water receiving tray 12. The air guide support 13 is provided with a second air outlet 152, and the water receiving tray 12 and the air guide support 13 together form a first air outlet 151. The first air guide plate 21 and the second air guide plate 22 are both rotatably connected to the air guide support 13.

[0111] As shown in Figure 11, the water receiving tray 12 can be located inside the outer casing 11 and below the indoor heat exchanger 3, and the water receiving tray 12 can be connected to the bottom of the outer casing 11. The air guide support 13 can be located inside the outer casing 11 and connected to the front of the outer casing 11 and the top of the water receiving tray 12. The water receiving tray 12 can be provided with an air passage opening. One end (lower end) of the air guide support 13 near the water receiving tray 12 can be connected to the water receiving tray 12 and connected to the end of the air passage opening, so that the water receiving tray 12 and the air guide support 13 enclose the first air outlet 151. The lower end of the outer casing 11 can be open, and the casing 1 can also include a cover plate, which covers the open end of the outer casing 11 and is provided with a clearance opening corresponding to and communicating with the first air outlet 151.

[0112] As shown in Figure 4, the water receiving tray 12 may be provided with a supporting step 124, which is located above the air passage opening. The bottom of the air guide support 13 may be provided with a supporting part 131, which is supported by the supporting step 124 and together with the water receiving tray 12 to form the first air outlet 151. The first rotating part 211 of the first air guide plate 21 may be rotatably connected to the supporting part 131 of the air guide support 13.

[0113] Of course, the first air vent 151 and the second air vent 152 can both be set on the outer casing 11.

[0114] In some exemplary embodiments, as shown in Figures 4 and 7, the housing 1 is provided with a first arc-shaped groove 132 and a second arc-shaped groove 133. The first arc-shaped groove 132 is configured to mount the first rotating part 211 and limit the rotation amplitude of the first rotating part 211, and the second arc-shaped groove 133 is configured to mount the second rotating part 221 and limit the rotation amplitude of the second rotating part 221. The first arc-shaped groove 132 and the second arc-shaped groove 133 can be provided on the air guide support 13 of the housing 1.

[0115] The shapes of the first rotating part 211 and the second rotating part 221 are adapted to the first arc-shaped groove 132 and the second arc-shaped groove 133, respectively. This facilitates limiting the rotation angle of the first air guide plate 21 and the second air guide plate 22 through mechanical limiting, and also facilitates overlapping sealing.

[0116] In some exemplary embodiments, the housing 1 is further provided with a first latch 1301 and a second latch 1302, as shown in FIG26. At least a portion of the first latch 1301 is located in the first arc-shaped groove 132, and at least a portion of the second latch 1302 is located in the second arc-shaped groove 133. The first latch 1301 is configured to be rotatably connected to the third connecting portion 2313 of the first air guide plate 21, and the second latch 1302 is configured to be rotatably connected to the third connecting portion 2313 of the second air guide plate 22. Connecting the third connecting portion 2313 by latches helps to reduce assembly difficulty and improve assembly efficiency.

[0117] The number of first clips 1301 is equal to the number of third connecting parts 2313 of the first air guide plate 21 and corresponds one-to-one. The number of second clips 1302 is equal to the number of third connecting parts 2313 of the second air guide plate 22 and corresponds one-to-one.

[0118] Alternatively, the third connecting part 2313 is not limited to the support shaft. For example, it can also adopt the structure of the first buckle 1301 or the second buckle 1302, and place the support shaft on the support carrier, which can also achieve the rotatable connection between the third connecting part 2313 and the support carrier.

[0119] In one embodiment, as shown in FIG26, the second buckle 1302 is fixed to the groove wall of the second arc-shaped groove 133. The housing 1 is also provided with a reinforcing part 1305, as shown in FIG24 and FIG26. The reinforcing part 1305 is located outside the first arc-shaped groove 132 and connected to the first buckle 1301, which can strengthen the first buckle 1301.

[0120] In some exemplary embodiments, at least one of the third connecting portion 2313 of the first air guide plate 21 and the third connecting portion 2313 of the second air guide plate 22 is configured as a support shaft. At least one of the first latch 1301 and the second latch 1302 is provided with a support hole 1303 and a guide notch 1304 communicating with the support hole 1303, as shown in FIG26. The support shaft is configured to pass through the corresponding support hole 1303 and be rotatably engaged with the support hole 1303. The guide notch 1304 is configured to allow the corresponding support shaft to enter the support hole 1303 radially along the corresponding support hole 1303 through the guide notch 1304.

[0121] When the third connecting portion 2313 of the first air guide plate 21 is configured as a support shaft, the first buckle 1301 is provided with a support hole 1303 and a guide notch 1304 communicating with the support hole 1303. The support shaft of the first air guide plate 21 is configured to pass through the support hole 1303 of the first buckle 1301 and be rotatably engaged with the support hole 1303. The guide notch 1304 is configured to allow the support shaft of the first air guide plate 21 to enter the support hole 1303 radially along the support hole 1303 of the first buckle 1301 through the guide notch 1304.

[0122] When the third connecting portion 2313 of the second air guide plate 22 is configured as a support shaft, the second latch 1302 is provided with a support hole 1303 and a guide notch 1304 communicating with the support hole 1303. The support shaft of the second air guide plate 22 is configured to pass through the support hole 1303 of the second latch 1302 and be rotatably engaged with the support hole 1303. The guide notch 1304 is configured to allow the support shaft of the second air guide plate 22 to enter the support hole 1303 radially along the support hole 1303 of the second latch 1302 through the guide notch 1304.

[0123] In some embodiments, the width of the guide notch 1304 is smaller than the diameter of the support hole 1303, and the width of the guide notch 1304 is smaller than the diameter of the support shaft.

[0124] During installation, the clearance surface of the support shaft can be aligned with the opening wall of the guide notch 1304 to reduce interference between the support shaft and the guide notch 1304, facilitating the quick entry of the support shaft into the support hole 1303. After being inserted into the support hole 1303, the width of the guide notch 1304 is smaller than the diameter of the support shaft, which helps prevent the support shaft from reversing and coming out of the guide notch 1304, thereby improving the anti-detachment effect of the air guide plate.

[0125] In some exemplary embodiments, as shown in Figures 4, 5, and 6, the water receiving tray 12 is provided with a first overlapping edge 121, a second overlapping edge 122, and a third overlapping edge 123 arranged sequentially along the circumference of the first air outlet 151. As shown in Figures 7, 8, and 9, the air guide support 13 is provided with a fourth overlapping edge 134 arranged opposite to the second overlapping edge 122 and connected to the first overlapping edge 121 and the third overlapping edge 123, and a fifth overlapping edge 135, a sixth overlapping edge 136, a seventh overlapping edge 137, and an eighth overlapping edge 138 arranged sequentially along the circumference of the second air outlet 152.

[0126] As shown in Figures 4 to 6, based on the first air guide plate 21 being located in the first position, the circumferential end of the first air guide plate 21 overlaps and seals with the first overlapping edge 121, the second overlapping edge 122, the third overlapping edge 123 and the fourth overlapping edge 134.

[0127] As shown in Figures 7 to 9, based on the fact that the first air guide plate 21 is located in the third position, the circumferential end of the first air guide plate 21 overlaps and seals with the fifth overlapping edge 135, the sixth overlapping edge 136, the end of the second air guide plate 22 near the first air guide plate 21, and the eighth overlapping edge 138.

[0128] As shown in Figures 7 to 9, based on the fact that the second air guide plate 22 is located in the fourth position, the circumferential end of the second air guide plate 22 overlaps and seals with the seventh overlapping edge 137, the sixth overlapping edge 136, the end of the first air guide plate 21 near the second air guide plate 22, and the eighth overlapping edge 138.

[0129] The first air guide plate 21 may have two parallel short sides and two parallel long sides. The long sides and short sides may be perpendicular to each other, and the short sides may be straight or curved. The first overlapping edge 121 and the third overlapping edge 123 may be short sides, used for overlapping and sealing with the two short sides of the first air guide plate 21. The second overlapping edge 122 and the fourth overlapping edge 134 may be long sides, used for overlapping and sealing with the two long sides of the first air guide plate 21.

[0130] The second air guide plate 22 may have two parallel short sides and two parallel long sides. The long sides and short sides may be perpendicular to each other, and the short sides may be straight or curved. The sixth overlapping edge 136 and the eighth overlapping edge 138 may be short sides, used to overlap and seal with the two short sides of the first air guide plate 21 and the two short sides of the second air guide plate 22. The fifth overlapping edge 135 and the seventh overlapping edge 137 may be long sides. The seventh overlapping edge 137 is used to overlap and seal with the long side of the second air guide plate 22 that is away from the first air guide plate 22, and the fifth overlapping edge 135 is used to overlap and seal with the long side of the first air guide plate 22 that is away from the second air guide plate 22.

[0131] The first overlapping edge 121, the second overlapping edge 122, the third overlapping edge 123, the fourth overlapping edge 134, the fifth overlapping edge 135, the sixth overlapping edge 136, the seventh overlapping edge 137, and the eighth overlapping edge 138 can be prismatic structures (in line contact with the first air guide plate 21 / second air guide plate 22) or planar structures (in surface contact with the first air guide plate 21 / second air guide plate 22), as long as they can achieve overlapping sealing.

[0132] In some exemplary embodiments, as shown in Figures 3 and 7, the air guide support 13 is provided with a receiving groove 139. Based on the second air guide plate 22 being located in the fifth position, at least a portion of the second air guide plate 22 is embedded in the receiving groove 139, such that one side surface of the second air guide plate 22 constitutes part of the channel wall of the second air outlet channel. This helps to reduce the wind resistance generated by the second air guide plate 22 and improves the air volume in the second and third air outlet modes.

[0133] In some exemplary embodiments, as shown in FIG25, the water receiving tray 12 is provided with a first support plate 125, and the air guide support 13 is provided with a second support plate 1306. The first support plate 125 is located in the air passage of the water receiving tray 12 and is configured to abut against the first air guide plate 21 when the air conditioner is in the first air outlet mode. The second support plate 1306 is located in the air passage of the air guide support 13 and is configured to abut against the first air guide plate 21 and the second air guide plate 22 when the air conditioner is in the second air outlet mode.

[0134] The first support plate 125 and the second support plate 1306 can improve the structural strength of the water receiving tray 12 and the air guide support 13, and also help improve the positional accuracy of the first air guide plate 21 and the second air guide plate 22. They can also prevent the first air guide plate 21 and the second air guide plate 22 from deforming, thereby improving the anti-detachment effect.

[0135] In some exemplary embodiments, the first air vent 151 and the second air vent 152 are located inside the housing 1. The water receiving tray 12 is also provided with a first air outlet 161 corresponding to and communicating with the first air vent 151 (as shown in Figure 12), forming a first air passage between the first air vent 151 and the first air outlet 161. The air guide support 13 is also provided with a second air outlet 162 corresponding to and communicating with the second air vent 152 (as shown in Figure 12), forming a second air passage between the second air vent 152 and the second air outlet 162. This facilitates the reasonable setting of the positions of the first air vent 151 and the second air vent 152, as well as the shapes of the first air guide plate 21 and the second air guide plate 22, according to requirements, which is beneficial to optimizing the structural layout of the air conditioner without affecting its appearance.

[0136] As shown in Figure 12, the first air outlet 161 is set horizontally, and the second air outlet 162 is set vertically. For example, if the first air outlet 161 is set downward and the second air outlet 162 is set forward, then the first air outlet mode is the downward air outlet mode, the second air outlet mode is the front air outlet mode, and the third air outlet mode is the dual air outlet mode.

[0137] In other embodiments, the first air vent 151 and the second air vent 152 can also be air outlets, eliminating the need for additional first air outlet 161 and second air outlet 162. In the above scheme, the first air outlet 161 is located on the water receiving tray 12, and the second air outlet 162 is located on the air guide support 13.

[0138] In some exemplary embodiments, the housing 1 is provided with an air inlet 111 communicating with the air duct 14, and the air inlet 111 is located at least one of the bottom and side of the housing 1. In other words, the air conditioner can have side air intake (as shown in Figures 16 and 18), or bottom air intake (as shown in Figures 15 and 17), or a combination of side and bottom air intake, which facilitates reasonable selection according to the installation scenario and helps to expand the scope of application scenarios.

[0139] In some exemplary embodiments, as shown in Figure 12, the width W1 of the first air outlet 161 is smaller than the width W2 of the second air outlet 162. This is beneficial in reducing the width of the air outlet opening on the ceiling plate of the ceiling-mounted air conditioner, thus optimizing the aesthetics of the decoration, while also meeting the needs for large air volume output over long distances, which helps improve the uniformity of indoor temperature.

[0140] In some exemplary embodiments, as shown in FIG12, an air outlet flange 163 protrudes from the second air outlet 162. Ventilation components such as canvas hoses can be fitted onto the air outlet flange 163, so that the air output from the second air outlet 162 can be transported to the air outlet opening on the ceiling 6 through the ventilation components.

[0141] Similarly, as shown in Figure 12, an air outlet flange 163 can also be provided at the first air outlet 161 so that the air output from the first air outlet 161 can be transported to the air outlet opening on the ceiling 6 through the ventilation component.

[0142] The end of the housing 1 connected to the air outlet flange 163 is set as the reference end 17, as shown in Figure 12. At least one of the rotation axis of the first air guide plate 21 and the rotation axis of the second air guide plate 22 is located on the side of the reference end 17 away from the air outlet flange 163.

[0143] Side-discharge airflow is generally forward-discharge airflow, so the reference end 17 can be the front end. Therefore, at least one of the rotation axes of the first air guide plate 21 and the second air guide plate 22 is located on the rear side of the air outlet flange 163, that is, inside the housing 1. In this way, the first air guide plate 21 and the second air guide plate 22 can be basically located inside the housing 1 during rotation.

[0144] In some exemplary embodiments, the air conditioner is configured to be used in conjunction with a first air outlet panel 51 and a second air outlet panel 52, as shown in FIG19. The first air outlet panel 51 is correspondingly disposed with a first air outlet 161, and the second air outlet panel 52 is correspondingly disposed with a second air outlet 162.

[0145] The first air outlet panel 51 and the second air outlet panel 52 are configured as engineering grilles for installation in the mounting carrier. Alternatively, the first air outlet panel 51 and the second air outlet panel 52 are configured as motorized panels connected to the housing 1.

[0146] In other words, the air conditioner provided in this application embodiment can be paired with ordinary engineering grilles, which are more in line with home decoration styles and are very popular with users; it can also be paired with an electric panel to further improve the user experience.

[0147] Through testing and verification, when the duct-type indoor unit provided in this application embodiment is used in conjunction with a common engineering grille, the hot air in heating mode can effectively reach the ground. As shown in the indoor temperature cloud map in Figure 21, the orange-red area is located near the ground (about 0.1m above the ground), indicating that the ground area has a high temperature.

[0148] In some exemplary embodiments, as shown in FIG12, the rotation axis of the first air guide plate 21 and the rotation axis of the second air guide plate 22 are located on opposite sides of the bisecting plane 18 perpendicular to the thickness direction of the housing 1. This allows for efficient use of the space in the thickness direction of the housing 1, which is beneficial for optimizing the structural layout of the air conditioner.

[0149] As shown in Figure 20, this application embodiment also provides a control method for an air conditioner in any of the above embodiments, the control method comprising:

[0150] Step S202: Determine that the current operating condition is under the set condensation condition;

[0151] Step S204: Obtain the air outlet mode of the air conditioner;

[0152] Step S206: Control the air guide mechanism 2 according to the air outlet mode of the air conditioner to limit condensation at the air outlet.

[0153] The setting of condensation conditions refers to the conditions under which condensation is likely to occur at the air vents during air conditioner operation. Condensation at the air vents refers to condensation occurring on components inside or near the air vents. Components near the air vents may include, but are not limited to: air guide plate assembly, water collection tray 12, air guide support 13, etc.

[0154] The control method provided in this application embodiment can control the air guide mechanism 2 according to the air outlet mode of the air conditioner when it is determined that condensation is likely to occur at the air outlet during the operation of the air conditioner, so as to limit the condensation at the air outlet, thereby further reducing the risk of water dripping caused by condensation in the air conditioner and further improving the user experience.

[0155] In some exemplary embodiments, determining that the current operating condition is a set condensation condition includes:

[0156] Obtain indoor temperature, indoor humidity, and the temperature of the indoor heat exchanger 3 of the air conditioner;

[0157] Based on the indoor temperature being greater than or equal to the first set temperature, the indoor humidity being greater than or equal to the set humidity, and the temperature of the indoor heat exchanger 3 of the air conditioner being less than or equal to the second set temperature, it is determined that the current operating condition is the set condensation condition.

[0158] When the indoor temperature is greater than or equal to the first set temperature and the indoor humidity is greater than or equal to the set humidity, it indicates that the indoor air is in a high-temperature and high-humidity state. When the temperature of the indoor heat exchanger 3 is less than or equal to the second set temperature, it indicates that the outlet air temperature is too low. Especially for multi-split air conditioners, when the temperature of the indoor heat exchanger 3 is less than or equal to the second set temperature, it indicates that the output energy of the outdoor unit is much greater than that required by the indoor unit, but the output cannot be reduced further, so the risk of condensation is very high.

[0159] When the outlet air temperature is too low and the indoor air is hot and humid, condensation is easily produced. Therefore, the current operating condition can be determined as the set condensation condition.

[0160] The temperature of the indoor heat exchanger 3 can be determined by measuring the temperature of its output pipe. The indoor temperature can be determined by an indoor temperature sensor. The indoor humidity can be determined by an indoor humidity sensor. Both the indoor temperature and humidity sensors can be located at the air inlet 111 of the air conditioner. The specific values ​​for the first set temperature, second set temperature, and set humidity are not limited and can be set appropriately according to requirements.

[0161] Of course, the method for determining the condensation condition is not limited to this. For example, the outlet air temperature can be directly detected to replace the temperature of the indoor heat exchanger 3. The indoor temperature and humidity can also be obtained through other means.

[0162] In some exemplary embodiments, the air guide mechanism 2 is controlled according to the air outlet mode of the air conditioner to limit condensation at the air outlet, including:

[0163] Based on whether the air conditioner is in the first air outlet mode or the second air outlet mode, control the air guide mechanism 2 to maintain the current state;

[0164] Since the air conditioner is in the third air outlet mode, the air guide mechanism 2 is controlled to switch the air outlet mode.

[0165] The first air outlet mode is a bottom air outlet mode, the second air outlet mode is a side air outlet mode, and the third air outlet mode is a dual air outlet mode.

[0166] When the air conditioner is in the first air outlet mode, the air guide plate assembly can completely close the second air outlet 152, effectively isolating the hot and cold air on both sides of the air guide plate assembly. Therefore, it can effectively prevent condensation from forming at the second air outlet 152. Thus, the air guide mechanism 2 can maintain its current state without adjustment.

[0167] Similarly, when the air conditioner is in the second air outlet mode, since the air guide plate assembly can completely close the first air outlet 151 and effectively isolate the hot and cold air on both sides of the air guide plate assembly, it can effectively prevent condensation from forming at the first air outlet 151. Therefore, the air guide mechanism 2 can maintain its current state without adjustment.

[0168] When the air conditioner is in the third air outlet mode, the airflow at the first air outlet 151 is significantly reduced compared to the first air outlet mode, resulting in uneven airflow distribution. This causes a backflow zone 19 to form in the area of ​​the first air outlet 151 that is far from the second air outlet 152 (as indicated by the small arrow on the left side of the lower air outlet in Figure 10). Consequently, hot and cold air will meet within the first air outlet 151. When the air conditioner is in the third air outlet mode for an extended period, condensation will form at the first air outlet 151, causing dripping water, for example, condensation forming on the inner wall of the backflow zone 19. Therefore, when the current operating condition is set to condensation and the air conditioner is in the third air outlet mode, it is necessary to switch the air outlet mode to prevent condensation from forming at the first air outlet 151.

[0169] In some exemplary embodiments, controlling the air guide mechanism 2 to switch the air outlet mode includes:

[0170] Control the air guide mechanism 2 to switch the air conditioner's air outlet mode from the third air outlet mode to the first air outlet mode.

[0171] This approach maintains a strong airflow, ensuring the user's current temperature control needs are met. It also facilitates rapid temperature regulation in the area surrounding the air conditioner, improving the current operating conditions by reducing the temperature difference between the hot and cold air at the first air vent 151, thereby lowering the risk of condensation at the first air vent 151.

[0172] Of course, you can also switch the air conditioner's air outlet mode to the second air outlet mode to avoid condensation at the first air outlet 151.

[0173] In some exemplary embodiments, the control method further includes:

[0174] Based on the air conditioner's air outlet mode switching from the third air outlet mode to the first air outlet mode and running for a first set time, the air guide mechanism 2 is controlled to switch the air conditioner's air outlet mode back from the first air outlet mode to the third air outlet mode.

[0175] Based on the step of the air conditioner switching from the first air outlet mode back to the third air outlet mode and running for a second set time, return to execute the action of the control air guide mechanism 2 to switch the air outlet mode of the air conditioner from the third air outlet mode back to the first air outlet mode.

[0176] In other words, after the air conditioner switches to the first air outlet mode and runs for a period of time (the first set time), it will switch back to the third air outlet mode to meet the user's need for airflow throughout the entire area; after the air conditioner runs in the third air outlet mode for a period of time (the second set time), it will switch back to the first air outlet mode. This cycle repeats, ensuring airflow throughout the entire area while minimizing condensation and dripping at the first air vent 151.

[0177] In some exemplary embodiments, the control method further includes:

[0178] Before controlling the air guide mechanism 2 to switch the air outlet mode, determine the air conditioner to run in the third air outlet mode for the third set duration.

[0179] In other words, based on determining that the air conditioner is operating in the third air outlet mode for a third set duration, the step of controlling the air guide mechanism 2 to switch the air outlet mode is executed. When it is determined that the current operating condition is the set condensation condition and the air conditioner's air outlet mode is the third air outlet mode, the air outlet mode is not switched immediately, but rather after running in the third air outlet mode for a period of time (the third set duration). This is because condensation does not occur immediately in the third air outlet mode, but only after a long period of operation. Therefore, switching the air outlet mode after running in the third air outlet mode for a period of time (the third set duration) is sufficient to meet the user's overall air outlet needs as much as possible.

[0180] The specific values ​​of the first, second, and third set durations are not restricted and can be set reasonably according to needs.

[0181] In some embodiments, the third set duration is equal to the second set duration. Thus, when the current operating condition is determined to be the set condensation condition and the air conditioner's air outlet mode is the third air outlet mode, the air guide mechanism 2 can operate periodically with a cycle of the third set duration (the state corresponding to the third air outlet mode) + the first set duration (the state corresponding to the first air outlet mode).

[0182] As shown in Figure 22, this application embodiment also provides a control method, applied to the air conditioner in any of the above embodiments, the control method including:

[0183] Step S302: Determine the target temperature regulation mode, which includes multiple temperature regulation modes;

[0184] Step S304: Control the air guide mechanism 2 according to the target temperature adjustment mode to make the air outlet mode of the air conditioner match the target temperature adjustment mode.

[0185] The control method provided in this application embodiment can reasonably control the air guide mechanism 2 according to the determined target temperature adjustment mode, so that the air outlet mode of the air conditioner is adapted to the target temperature adjustment mode, thereby improving the comfort of each temperature adjustment mode and enhancing the user experience.

[0186] The target temperature adjustment mode can be determined by external commands, such as commands sent by the user via remote control, control panel, or mobile terminal (such as mobile phone, computer, etc.); or it can be determined automatically, such as automatically determining a suitable target adjustment mode based on indoor temperature information, user habits, etc.

[0187] In some exemplary embodiments, the multiple temperature control modes include at least one of a first cooling mode, a second cooling mode, and a third cooling mode. The air outlet modes of the air conditioner include a first air outlet mode, a second air outlet mode, and a third air outlet mode. Specifically, the first air outlet mode is a bottom air outlet mode, the second air outlet mode is a side air outlet mode, and the third air outlet mode is a dual air outlet mode.

[0188] The air guide mechanism 2 is controlled according to the target temperature adjustment mode to adapt the air conditioner's air outlet mode to the target temperature adjustment mode, including:

[0189] Based on the target temperature regulation mode being the first cooling mode, the air guide mechanism 2 is controlled to operate, causing the air conditioner to output air in the first air outlet mode;

[0190] Based on the target temperature regulation mode being the second cooling mode, the air guide mechanism 2 is controlled to operate, causing the air conditioner to output air in the second air outlet mode;

[0191] Based on the target temperature regulation mode being the third cooling mode, the air guide mechanism 2 is controlled to operate, causing the air conditioner to output air in the third air outlet mode.

[0192] In the first cooling mode, the air conditioner blows air out in the first air outlet mode, that is, downward air outlet, which makes it easy to quickly reduce the ambient temperature to the target set temperature. Therefore, the first cooling mode can be called the rapid cooling mode.

[0193] In the second cooling mode, the air conditioner uses the second air outlet mode, which is side air outlet, to deliver air over a long distance. This can reduce the indoor temperature relatively slowly. Therefore, the second cooling mode can be called the normal cooling mode.

[0194] In the third cooling mode, the air conditioner uses the third air outlet mode, which is a dual air outlet, and can deliver cool air to both nearby and distant locations. Therefore, the third cooling mode can be called the all-area cooling mode.

[0195] In some exemplary embodiments, based on the target temperature adjustment mode being a first cooling mode, the air guide mechanism 2 is controlled according to the target temperature adjustment mode to adapt the air outlet mode of the air conditioner to the target temperature adjustment mode, and the method further includes:

[0196] Based on the set duration of the air conditioner's first air outlet mode, the air guide mechanism 2 is controlled to switch the air conditioner to the second air outlet mode.

[0197] In rapid cooling mode, after the ambient temperature is quickly reduced by the first air outlet mode, switching to the second air outlet mode can prevent cold air from blowing directly on the user, thus improving the user experience.

[0198] As for the specific duration, there are no restrictions; it can be adjusted according to needs.

[0199] In some exemplary embodiments, the multiple temperature control modes include at least one of a first heating mode, a second heating mode, and a third heating mode.

[0200] The air guide mechanism 2 is controlled according to the target temperature adjustment mode to adapt the air conditioner's air outlet mode to the target temperature adjustment mode, including:

[0201] Based on the target temperature adjustment mode being the first heating mode, the air guide mechanism 2 is controlled to operate, causing the air conditioner to output air in the first air outlet mode;

[0202] Based on the target temperature adjustment mode being the second heating mode, the air guide mechanism 2 is controlled to operate, causing the air conditioner to output air in the second air outlet mode;

[0203] Based on the target temperature adjustment mode being the third heating mode, the air guide mechanism 2 is controlled to operate, causing the air conditioner to output air in the third air outlet mode.

[0204] In the first heating mode, the air conditioner blows air out in the first air outlet mode, that is, downward air outlet, which makes it easy to quickly raise the ambient temperature to the target set temperature. Therefore, the first heating mode can be called the rapid heating mode.

[0205] In the second heating mode, the air conditioner uses the second air outlet mode, which is side air outlet, to deliver air over a long distance. This allows the indoor temperature to rise relatively slowly. Therefore, the second heating mode can be called the normal heating mode.

[0206] In the third heating mode, the air conditioner uses the third air outlet mode, which is a dual air outlet, to deliver hot air to both nearby and distant locations. Therefore, the third heating mode can be called the all-area heating mode.

[0207] In some exemplary embodiments, the first cooling mode is set as the default cooling mode, and the second and third cooling modes are set as manually selected cooling modes.

[0208] The first heating mode is set to the default heating mode, and the second and third heating modes are set to manually selected heating modes.

[0209] For example, after the air conditioner is turned on, it can automatically acquire parameters (such as indoor temperature and outdoor temperature) and then automatically select a cooling mode or a heating mode. If the user does not further select a specific target cooling mode or target heating mode, the air conditioner will default to the first cooling mode or the first heating mode. If the user further selects a specific target cooling mode or target heating mode, the air conditioner will enter the user-selected target cooling mode (second cooling mode or third cooling mode) or target heating mode (second heating mode or third heating mode).
