The air guide plate has a rotating part at one end in the width direction, and a first connecting part and a second connecting part at each end in the length direction. The first connecting part is connected to a drive mechanism, and the second connecting part is rotatably connected to a support carrier. The rotating part also has at least one third connecting part located between the first and second connecting parts, and is rotatably connected to the support carrier to prevent the air guide plate from detaching from the support carrier.

Description

Technical Field

[0001] This application relates to, but is not limited to, the field of household appliance technology, and more specifically, to an air guide plate and an air conditioner. Background Technology

[0002] In related technologies, the air guide plate of an air conditioner is located inside the air vent, and rotating parts are provided at both ends along its length, allowing the air guide plate to rotate around a pivot within the air vent. With this structure, during use, the air guide plate is prone to bending, deformation, interference, or other issues that can cause its rotating parts to deviate from the set axis of rotation and detach, thus affecting its normal operation. Utility Model Content

[0003] The technical problem to be solved by this application is to provide an air guide plate and an air conditioner that helps prevent the air guide plate from falling off during use, thereby improving the reliability of the air guide plate.

[0004] This application provides an air guide plate, wherein one end of the air guide plate in the width direction is provided with a rotating part, and the two ends of the rotating part in the length direction are respectively provided with a first connecting part and a second connecting part. The first connecting part is configured to be connected to a driving mechanism, and the second connecting part is configured to be rotatably connected to a supporting carrier. The rotating part is also provided with at least one third connecting part, which is located between the first connecting part and the second connecting part. The third connecting part is configured to be rotatably connected to the supporting carrier to prevent the air guide plate from detaching from the supporting carrier.

[0005] The air guide plate provided in this application embodiment transfers the rotating part of the air guide plate to one end in the width direction of the air guide plate. In addition to the first connecting part and the second connecting part respectively provided at both ends in the length direction of the rotating part, at least one third connecting part is added. The first connecting part is connected to the driving mechanism, and the second connecting part can be connected to the supporting carrier to ensure that the air guide plate can be stably supported and can rotate under the drive of the driving mechanism. Furthermore, since the rotating part of the air guide plate is transferred 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 supporting carrier, allowing the rotating part to also be provided with at least one third connecting part. The third connecting part can also be rotatably connected to the supporting carrier, realizing multi-point support connection between the air guide plate and the supporting carrier. This helps prevent the rotating part of the air guide plate from deviating from the set rotation axis and detaching from the supporting 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.

[0006] This application provides an air conditioner, including: a housing, the housing having an air duct and an air outlet communicating with the air duct; an air guiding mechanism, including a drive mechanism and an air guiding plate as described in any of the above embodiments, the air guiding plate being disposed at the air outlet, and a first connecting portion of the air guiding plate being connected to the drive mechanism, the housing forming a support carrier for the air guiding plate, and a second connecting portion and a third connecting portion of the air guiding plate being rotatably connected to the housing.

[0040] In the above sectional structural diagram, the section lines are omitted, but this does not affect the overall structural representation. Detailed Implementation

[0041] 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.

[0042] This application provides an air guide plate, such as... Figure 1 and Figure 2 As shown, a rotating part 231 is provided at one end of the air guide plate in the width direction, and a first connecting part 2311 and a second connecting part 2312 are provided at both ends in the length direction of the rotating part 231. 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. The rotating part 231 is also provided with at least one third connecting part 2313, which is located between the first connecting part 2311 and the second connecting part 2312. The third connecting part 2313 is configured to be rotatably connected to the support carrier to restrict the air guide plate from detaching from the support carrier.

[0043] The air guide plate provided in this embodiment of the application transfers the rotating part 231 of the air guide plate 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 driving mechanism, and the second connecting part 2312 can be connected to the supporting carrier to ensure that the air guide plate can be stably supported and can rotate under the drive of the driving mechanism. Furthermore, since the rotating part 231 of the air guide plate is transferred 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 it is adjacent to the supporting 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 to prevent the air guide plate from deviating from the set rotation axis and falling off the support carrier due to bending, deformation, interference, etc., and plays a good role in limiting and preventing detachment, thereby improving the reliability of the air guide plate.

[0044] The drive mechanism may be, but is not limited to, a stepper motor. Alternatively, the drive mechanism may also include a drive component and a transmission component connected to the drive component. The support carrier may be, but is not limited to, the housing 1 of the air conditioner.

[0045] like Figure 1 and Figure 2 As shown, 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.

[0046] In some exemplary embodiments, such as Figure 1 and Figure 2As shown, 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 (such as...). Figure 1 and Figure 2 (As shown).

[0047] When the first connecting part 2311 includes a rotating shaft, the output shaft of the drive mechanism can be provided with a shaft hole; when the first connecting part 2311 includes a shaft hole, the output shaft of the drive mechanism can be provided with a rotating shaft. Thus, the drive mechanism 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 mechanism can drive the first air guide plate 21 / second air guide plate 22 to rotate.

[0048] When the second connecting part 2312 includes a rotating shaft, the support carrier can be provided with a shaft hole (e.g., Figure 25 (As shown); 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 first air guide plate 21 / second air guide plate 22 can rotate relative to the support carrier.

[0049] When the third connecting part 2313 includes a support shaft, the support carrier can be provided with a support hole 1303 and a guide notch 1304 communicating with the support hole 1303, so that the support shaft can be inserted into the support hole 1303 by the guide notch 1304 and can rotate relative to the support hole 1303.

[0050] In some exemplary embodiments, such as Figure 1 As shown, 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, which is beneficial to reducing frictional resistance.

[0051] In some exemplary embodiments, such as Figure 22 As shown, the sidewall of the support shaft includes a clearance surface 2315 and a first arc surface 2316 connected circumferentially along the support shaft. The number of clearance surfaces 2315 can be one or two.

[0052] 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.

[0053] In some exemplary embodiments, such as Figure 2 As shown, the air guide plate includes an air guide plate body 23 and an insulation layer 24. The insulation layer 24 is located on one side of the air guide plate body 23 in the thickness direction and is connected to the air guide plate body 23. This helps to isolate the heat transfer between the two sides of the air guide plate, thereby helping to prevent condensation from occurring on the air guide plate.

[0054] In some exemplary embodiments, such as Figure 2 As shown, the circumferential end of the air guide plate is provided with a sealing edge 25, which is configured to overlap and seal with the outer circumferential edge of the corresponding air outlet, so that the air guide plate closes and seals the corresponding air outlet. The air guide plate body 23 and / or the insulation layer 24 are provided with sealing edges 25.

[0055] Conventional air deflectors are located inside the air vent, and a gap needs to be left between them and the vent wall to avoid interference during the deflector's rotation. Therefore, the air deflector cannot completely close the air vent when closed.

[0056] In this design, the rotating part 231 of the air guide plate is moved to one end in the width direction of the air guide plate, and a sealing edge 25 is provided at the circumferential end of the air guide plate. This ensures that when the corresponding air outlet is closed, the circumferential end of the air guide plate is not inside the air outlet, but located on the circumferential outside of the air outlet (for example, the position of the air guide plate can be moved from inside the air outlet to the upstream or downstream side of the air outlet). The sealing edge 25 at the circumferential end of the air guide plate can overlap and seal with the overlapping edge on the circumferential outside of the air outlet, so that the corresponding air outlet can be completely closed. This achieves the sealing of the air outlet by the air guide plate assembly, which can effectively isolate the hot and cold air on both sides of the air guide plate in the closed state. This helps to prevent condensation and dripping water from the air guide plate in the closed state, and also prevents air leakage and whistling from the air outlet in the closed state, thereby improving the user experience.

[0057] 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.

[0058] 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.

[0059] In some exemplary embodiments, such as Figure 1 As shown, the rotating part 231 is located at one end of the air guide plate body 23 in the width direction, 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 improving the connection strength between the insulation layer 24 and the air guide plate body 23.

[0060] In some exemplary embodiments, such as Figure 22 As shown, the cross-sectional outline of the filling groove 232 is set in 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.

[0061] 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.

[0062] 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 as needed. The insulation layer 24 can be a foam part.

[0063] 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, which helps to improve the service life of the air guide plate.

[0064] For example, 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.

[0065] Of course, the air guide plate body 23 and the insulation layer 24 can also be a separate assembly structure.

[0066] In some exemplary embodiments, such as Figure 22As shown, 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, with the support shaft located within the clearance notch 2314.

[0067] Among them, such as Figure 22 As shown, 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.

[0068] In some embodiments, such as Figure 22 As shown, the air guide plate body 23 is also 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 (for example, a roughly U-shaped space) that communicates with the clearance notch 2314. This can effectively separate the support shaft from 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, and preventing it from entering the clearance notch 2314 and contacting the support shaft.

[0069] In some exemplary embodiments, such as Figure 22 As shown, 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.

[0070] In related technologies, the diameter of the rotating parts 231 at both ends of the guide plate along its length is usually roughly the same as the thickness of the guide plate body 23, and is relatively thin, making it easy to detach. However, in this solution, the rotating parts 231 are relatively thicker. This is partly to achieve multi-point support connection with the support carrier to prevent the guide plate from detaching, and partly to facilitate the setting of the filling groove 232 so that the insulation layer 24 can achieve a better sealing effect.

[0071] 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.

[0072] In some exemplary embodiments, the end of the air guide plate 22 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.

[0073] In some exemplary embodiments, such as Figure 1As shown, 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.

[0074] In some exemplary embodiments, such as Figure 1 As shown, the surface of the air guide plate body 23 facing the insulation layer 22 is provided with reinforcing ribs, which helps to improve the strength of the air guide plate body 23 and also increases the contact area between the insulation layer 22 and the air guide plate body 23, thereby improving the connection strength.

[0075] like Figures 1 to 19 As shown in the figure, this application provides an air conditioner, including: a housing 1 and an air guide mechanism 2.

[0076] like Figure 3 As shown, the housing is provided with an air duct 14 and an air outlet connected to the air duct 14.

[0077] The air guiding mechanism includes a drive mechanism (not shown in the figure) and an air guide plate as described in any of the above embodiments. The air guide plate is located at the air outlet, and the first connecting portion 2311 of the air guide plate is connected to the drive mechanism. The housing forms a support carrier for the air guide plate, and the second connecting portion 2312 and the third connecting portion 2313 of the air guide plate are rotatably connected to the housing.

[0078] The air conditioner provided in this application embodiment has all the above-mentioned beneficial effects because it includes the air guide plate of any of the above embodiments, and will not be repeated here.

[0079] In some exemplary embodiments, such as Figure 3 As shown, there are multiple air vents, including a first air vent 151 and a second air vent 152. The first air vent 151 and the second air vent 152 have different air outlet directions. The first air vent 151 is configured to connect with the air duct 14 to form a first air outlet channel. 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 connects with the air duct 14, the air outlet channel formed by their connection is the first air outlet channel. Similarly, when the second air vent 152 connects with the air duct 14, the air outlet channel formed by their connection is the second air outlet channel.

[0080] The first air vent 151 and the second air vent 152 can be air outlets of an air conditioner, or openings inside the air conditioner located upstream of the air outlet. An indoor heat exchanger 3 and a fan 4 can be installed inside the air duct 14. The fan 4 rotates, drawing indoor air into the air duct 14, where it exchanges heat with the indoor heat exchanger 3, and then is discharged into the indoor space through the air outlet channel, thus regulating the temperature of the indoor air.

[0081] like Figure 3As shown, there are two air guide plates, namely the first air guide plate 21 and the second air guide plate 22. 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 (e.g., Figure 7 , Figure 15 and Figure 16 (As shown), the second air outlet mode where the first air outlet channel is disconnected and the second air outlet channel is open (e.g.) Figure 3 , Figure 17 and Figure 18 As shown), and a third air outlet mode in which both the first and second air outlet channels are open (as shown). Figure 10 (As shown). The air guiding mechanism 2 may also include a drive mechanism connected to the air guiding plate assembly, the drive mechanism being configured to drive the first air guiding plate 21 and the second air guiding plate 22 to move relative to the housing 1.

[0082] The air conditioner provided in this application embodiment has three air outlet modes by setting a first air outlet 151 and a second air outlet 152 with different air outlet directions, as well as a first air guide plate 21 and a second air guide plate 22 that cooperate with the first air outlet 151 and the second air outlet 152. This allows the air conditioner to have three air outlet modes, which makes it convenient for users to choose the air outlet mode according to their needs, which helps to meet the different air outlet needs of users and thus improves the user experience.

[0083] Furthermore, the first air vent 151 and the second air vent 152 only require the cooperation of the first air guide plate 21 and the second air guide plate 22 to control their opening and closing and achieve the switching of three air outlet modes, without the need for other wind-blocking or air-guiding components (such as movable volutes or other deformable or movable wind-blocking mechanisms), which helps to simplify the structure of the air conditioner and reduce production costs.

[0084] 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 that includes an indoor unit and an outdoor unit, or it can be an integrated air conditioner.

[0085] In some embodiments, the first air vent 151 can be a downdraft vent, discharging air downwards; the second air vent 152 can be a side vent, discharging air horizontally. Therefore, the first air outlet mode is a downdraft mode, the second air outlet mode is a downdraft mode, and the third air outlet mode is a dual-air outlet mode. When the user needs rapid cooling or rapid heating, they can select the first air outlet mode, in which case the airflow will be discharged downwards through the first air outlet channel. Figure 7 , Figure 15 and Figure 16 As shown, this facilitates rapid temperature reduction 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, such as... Figure 3 , Figure 17 and Figure 18 As shown, this design facilitates airflow over a long distance, avoiding direct airflow onto the user. When the user desires uniform cooling or heating throughout the entire area, they can select the third airflow mode, in which case the airflow is blown out through both the first and second airflow channels, as shown. Figure 10 As shown, it can quickly adjust the temperature of the nearby area below, and it can also deliver air over long distances, enabling rapid temperature adjustment of distant areas as well.

[0086] In related technologies, ordinary central air conditioning duct-type indoor units are typically installed embedded in the ceiling, with one air inlet and one air outlet. They usually employ a bottom-intake, side-outtake configuration with an engineered grille (fixed airflow direction). However, this airflow method prevents the heated air from reaching the ground, resulting in a large blind spot and significant temperature differences between near and far areas. Some products are equipped with electric panels (adjustable airflow direction), allowing for airflow direction adjustment, but these have drawbacks such as high cost, difficulty in home decoration matching, and installation difficulties, resulting in a relatively low actual standard installation rate. Some products use a bottom-outtake design, but this can lead to the cooling air blowing directly onto people, resulting in lower product acceptance.

[0087] The air conditioner provided in this application embodiment has two air outlets with different airflow directions, enabling three different airflow modes. Users can choose according to their needs. The first airflow mode solves the problem of hot air not reaching the ground in heating mode; the second airflow mode solves the problem of cold air blowing directly on people in cooling mode; and the third airflow mode solves the problems of large airflow blind spots and large temperature differences between near and far, effectively addressing the pain points of existing duct-type indoor units. Furthermore, this air conditioner can be paired with a standard engineering grille for better coordination with home décor, making it popular with users; or it can be paired with an electric control panel to further enhance the user experience.

[0088] In some exemplary embodiments, such as Figure 3 As shown, 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.

[0089] like Figure 13 and Figure 14 As shown, 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.

[0090] like Figure 13 and Figure 14As shown, 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.

[0091] 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 vent 151 is open and the second air vent 152 is closed, and the air conditioner is in the first air outlet mode. Figure 7 As shown.

[0092] 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 vent 151 is closed and the second air vent 152 is open, and the air conditioner is in the second air outlet mode. Figure 3 As shown.

[0093] 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, the second air vent 152 opens, and the air conditioner is in the third air outlet mode. Figure 10 As shown.

[0094] 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.

[0095] 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.

[0096] In some exemplary embodiments, such as Figure 4 As shown, the rotating part of the first air guide plate 21 is designated as the first rotating part 211, and the first rotating part 211 is located between the first air outlet 151 and the second sub-air outlet 1522. The rotating part of the second air guide plate 22 is designated as the second rotating part 221, and the second rotating part 221 can be located at the end of the second air guide plate 22 away from the first air guide plate 21, or it can be located at the end of the second air guide plate 22 closer to the first air guide plate 21.

[0097] In other words, such as Figure 4As shown, the rotating part 231 of the first air guide plate 21 is disposed between the first air outlet 151 and the second sub-air outlet 1522, 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 air guide plate 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 air guide plate 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.

[0098] The position of the rotating part 231 of the second air guide plate 22 is not limited; it can be located at one end of the width direction of the second air guide plate 22 (either end in the width direction is acceptable, such as...). Figure 7 (as shown), or it can be set between the two ends of the second air guide plate 22 in the width direction.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] In some exemplary embodiments, the housing 1 is provided with a plurality of overlapping edges (such as the first overlapping edge to the eighth overlapping edge described below), and each air vent is provided with an overlapping edge on its circumferential outer side. The overlapping edges are configured to overlap and seal with the first air guide plate 21 and / or the second air guide plate 22, so that the first air guide plate 21 and / or the second air guide plate 22 seal the closed first air vent 151 or second air vent 152.

[0103] Conventional air guide vanes are located inside the air vent, requiring a gap between them and the vent wall to prevent interference during rotation. Therefore, the air guide vane cannot completely close the air vent when closed. Consequently, if the first air guide vane 21 and the second air guide vane 22 adopt a conventional configuration, during air conditioning operation, when some air guide vanes are closed, some airflow will pass through the gaps, failing to effectively isolate the hot and cold air on either side of the closed air guide vane. 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, causing dripping water.

[0104] In the air conditioner provided in this application embodiment, the first air guide plate 21 and the second air guide plate 22 are mainly used as air dampers. The circumferential ends of each air guide plate are not inside the air vent, but are 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 guiding mechanism 2 closes the first air vent 151 or the second air vent 152, the circumferential ends of the first air guide plate 21 / second air guide plate 22 are 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. This can effectively isolate the hot and cold air on both sides of the air guide plate in the closed state, thereby helping to avoid condensation and dripping water on the air guide plate in the closed state, and also preventing air leakage and whistling at the air vent in the closed state, thus improving the user experience.

[0105] In some exemplary embodiments, such as Figure 4 and Figure 7 As shown, 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 install the first rotating part 211 and limit the rotation amplitude of the first rotating part 211. The second arc-shaped groove 133 is configured to install the second rotating part 221 and limit the rotation amplitude of the second rotating part 221.

[0106] 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.

[0107] In some exemplary embodiments, the housing 1 is further provided with a first latch 1301 and a second latch 1302, such as Figure 25 As shown. At least a portion of the first latch 1301 is located within the first arc-shaped groove 132, and at least a portion of the second latch 1302 is located within the second arc-shaped groove 133. The first latch 1301 is rotatably connected to the third connecting portion 2313 of the first air guide plate 21, and the second latch 1302 is rotatably connected to the third connecting portion 2313 of the second air guide plate 22. Connecting the third connecting portion 2313 using latches helps reduce assembly difficulty and improve assembly efficiency.

[0108] 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.

[0109] 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.

[0110] In one embodiment, such as Figure 25 As shown, the second buckle 1302 is fixed to the groove wall of the second arc-shaped groove 133. The housing 1 also has a reinforcing part 1305, such as... Figure 23 and Figure 25 As shown, 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.

[0111] 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, such as... Figure 25 As shown. 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] In some exemplary embodiments, the first air vent 151 and the second air vent 152 are located inside the housing 1. The housing 1 also has a first air outlet 161 corresponding to and communicating with the first air vent 151 (e.g., Figure 12 (as shown) and the second air outlet 162 connected to the second air outlet 152 (as shown) Figure 12 (As shown).

[0117] A first air passage is formed between the first air vent 151 and the first air outlet 161, and a second air passage is formed between the second air vent 152 and the second air outlet 162. This allows for 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, as needed. This helps to optimize the structural layout of the air conditioner without affecting its appearance.

[0118] In some embodiments, such as Figure 12As shown, the first air outlet 161 is a bottom air outlet, the second air outlet 162 is a side air outlet, so the first air outlet mode is the bottom air outlet mode, the second air outlet mode is the side air outlet mode, and the third air outlet mode is the dual air outlet mode.

[0119] 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 two ways: firstly, it reduces the width of the air outlet opening on the ceiling plate of the ceiling-mounted air conditioner, which helps to optimize the aesthetics of the decoration; secondly, it meets the needs of large air volume output over long distances, which helps to improve the uniformity of indoor temperature.

[0120] In some exemplary embodiments, such as Figure 12 As shown, 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.

[0121] Similarly, such as Figure 12 As shown, an air outlet flange 163 may 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.

[0122] The end of the housing 1 connected to the air outlet flange 163 is set as the reference end 17. 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.

[0123] Side-discharge airflow is generally forward-discharge airflow, so the reference end 17 can be the front end, such as... Figure 12 As shown, 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 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 located substantially inside the housing 1 during rotation.

[0124] In some exemplary embodiments, the air conditioner is configured to be used in conjunction with the first air outlet panel 51 and the second air outlet panel 52, such as Figure 12 As shown. The first air outlet panel 51 is correspondingly set with the first air outlet 161, and the second air outlet panel 52 is correspondingly set with the second air outlet 162.

[0125] 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.

[0126] 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.

[0127] Tests have verified that when the ducted indoor unit provided in this application is used in conjunction with a standard engineering grille, the hot air in heating mode can effectively reach the ground. Figure 21 As shown in the indoor temperature cloud map, the orange-red area is located near the ground (about 0.1m above the ground), indicating that the ground area has a higher temperature.

[0128] In some exemplary embodiments, such as Figure 12 As shown, 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.

[0129] In some exemplary embodiments, such as Figure 3 and Figure 7 As shown, 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.

[0130] Among them, such as Figure 11 As shown, 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.

[0131] like Figure 4 As shown, 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.

[0132] like Figure 4and Figure 7 As shown, in the above scheme, the first arc-shaped groove 132 and the second arc-shaped groove 133 are disposed on the air guide support 13, and the first arc-shaped groove 132 can be disposed on the support part 131. In the above scheme, the first air outlet 161 is disposed on the water receiving tray 12, and the second air outlet 162 is disposed on the air guide support 13.

[0133] Of course, the first air vent 151 and the second air vent 152 can both be set on the outer casing 11.

[0134] 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 the bottom and / or side of the housing 1. In other words, the air conditioner can draw air from the side (e.g., Figure 16 and Figure 18 As shown), it can also have bottom air intake (such as...). Figure 15 and Figure 17 As shown in the figure, it is convenient to select the appropriate option according to the installation scenario, which helps to expand the scope of application scenarios.

[0135] In some exemplary embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the water receiving tray 12 has 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 vent 151. Figure 7 , Figure 8 and Figure 9 As shown, the air guide support 13 is provided with a fourth overlapping edge 134 that is opposite to the second overlapping edge 122 and connected to the first overlapping edge and the third overlapping edge, 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.

[0136] like Figures 4 to 6 As shown, 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.

[0137] like Figures 7 to 9 As shown, based on the first air guide plate 21 being 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.

[0138] like Figures 7 to 9 As shown, based on the second air guide plate 22 being 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.

[0139] 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.

[0140] 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 side 136 and the eighth overlapping side 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 side 135 and the seventh overlapping side 137 may be long sides, used to overlap and seal with the two long sides of the second air guide plate 22.

[0141] 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.

[0142] In some exemplary embodiments, such as Figure 3 and Figure 7 As shown, the air guide support 13 is provided with a receiving groove 139. Since the second air guide plate 22 is located in the fifth position, at least a portion of the second air guide plate 22 is embedded in the receiving groove 139, so that one side of the second air guide plate 22 forms 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 helps to increase the air volume in the second and third air outlet modes.

[0143] In some exemplary embodiments, such as Figure 24 As shown, 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.

[0144] 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.

[0145] like Figure 20 As shown in the embodiments, this application also provides a control method, applied to the air conditioner in any of the above embodiments, the control method including:

[0146] Step S202: Determine the target temperature regulation mode, which includes multiple temperature regulation modes;

[0147] Step S204: 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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:

[0152] 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;

[0153] 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;

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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 simultaneously. Therefore, the third cooling mode can be called the all-area cooling mode.

[0158] 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:

[0159] 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.

[0160] 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.

[0161] The specific duration can be set without restriction and can be adjusted as needed.

[0162] 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.

[0163] 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:

[0164] 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;

[0165] 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;

[0166] 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.

[0167] 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.

[0168] 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.

[0169] In the third heating mode, the air conditioner uses the third air outlet mode, which is dual air outlet, and can deliver hot air to both nearby and distant locations simultaneously. Therefore, the third heating mode can be called the whole-area heating mode.

[0170] 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.

[0171] 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.

[0172] 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).

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

[0174] The current operating condition is confirmed to be under the set condensation condition;

[0175] Get the air conditioner's airflow mode;

[0176] The air guide mechanism 2 is controlled according to the air outlet mode of the air conditioner to limit condensation at the air outlet.

[0177] 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.

[0178] 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.

[0179] In some exemplary embodiments, determining that the current operating condition is a set condensation condition includes:

[0180] Obtain indoor temperature, indoor humidity, and the temperature of the indoor heat exchanger 3 of the air conditioner;

[0181] 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.

[0182] 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.

[0183] 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.

[0184] 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 as needed.

[0185] 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.

[0186] 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:

[0187] 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;

[0188] Since the air conditioner is in the third air outlet mode, the air guide mechanism 2 is controlled to switch the air outlet mode.

[0189] 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.

[0190] 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.

[0191] 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.

[0192] When the air conditioner is in the third air outlet mode, under the same air volume, the air volume at the first air outlet 151 is significantly reduced compared to the first air outlet mode. This leads to uneven air velocity distribution, causing a backflow zone 19 to form in the area of ​​the first air outlet 151 that is far from the second air outlet 152 (e.g., Figure 10 (The area indicated by the small arrow on the left side of the lower air outlet) will be where hot and cold air meet in 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 water droplets, for example, condensation will form on the inner wall of the return flow area 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 avoid condensation at the first air outlet 151.

[0193] In some exemplary embodiments, controlling the air guide mechanism 2 to switch the air outlet mode includes:

[0194] 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.

[0195] 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.

[0196] 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.

[0197] In some exemplary embodiments, the control method further includes:

[0198] 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.

[0199] 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.

[0200] 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 continuously, ensuring airflow throughout the entire area while minimizing condensation and dripping at the first air vent 151.

[0201] In some exemplary embodiments, the control method further includes:

[0202] Before controlling the air guide mechanism 2 to switch the air outlet mode, determine that the air conditioner will run in the third air outlet mode for a third set duration, and then execute the step of controlling the air guide mechanism 2 to switch the air outlet mode.

[0203] In other words, 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 outlet mode is not switched immediately. Instead, it is switched 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.

[0204] The specific values ​​of the first, second, and third set durations are not restricted and can be set reasonably as needed.

[0205] 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).
