[0001] This utility model 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, during the cooling operation of an air conditioner, cold air blows onto the air guide vane, causing the vane's temperature to drop. However, during use, the outer surface of the air guide vane comes into contact with warm outside air, making it prone to condensation and dripping water, resulting in a poor user experience. 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 to reduce the risk of condensation on the air guide plate.

[0004] This application provides an air guide plate, which includes an air guide plate body and an insulation layer.

[0005] The air guide plate provided in this embodiment has a double-layer structure comprising an air guide plate body and an insulation layer. The insulation layer provides good heat insulation, reducing heat transfer between the two sides of the air guide plate, thereby reducing the temperature difference between the outer surface of the air guide plate and the outside air, and further reducing the risk of condensation and dripping. Furthermore, the insulation layer and the air guide plate body are integrated into a single structure, resulting in high connection strength, resistance to separation, and good adhesion, which enhances the insulation and anti-condensation effect.

[0035] 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.

[0036] like Figure 1 and Figure 2 As shown, this application embodiment provides an air guide plate, including an air guide plate body 23 and an insulation layer 24. The insulation layer 24 is fixed to one side of the thickness direction of the air guide plate body 23, and the insulation layer 24 and the air guide plate body 23 are configured as an integral structure.

[0037] The air guide plate provided in this embodiment has a double-layer structure comprising an air guide plate body 23 and an insulation layer 24. The insulation layer 24 provides good heat insulation, reducing heat transfer between the two sides of the air guide plate, thereby reducing the temperature difference between the outer surface of the air guide plate and the outside air, and further reducing the risk of condensation and dripping. Furthermore, the insulation layer 24 and the air guide plate body 23 are integrated into a single structure, resulting in high connection strength, resistance to separation, and good adhesion, which enhances the insulation and anti-condensation effect.

[0038] In some exemplary embodiments, the air guide plate body 23 is an injection molded part. The insulation layer 24 is provided as a foam part.

[0039] During the production process, the air guide plate body 23 can be injection molded first, and then placed into the mold of the insulation layer 24. The liquid insulation layer 24 material is injected into the mold. After curing, the insulation layer 24 and the air guide plate body 23 form an integrated structure.

[0040] Of course, the air guide plate body 23 is not limited to injection molded parts; for example, it can also be extruded parts or metal parts (such as cast or stamped metal parts). The insulation layer 24 is also not limited to foam parts; for example, it can also be plastic parts.

[0041] Of course, the air guide plate body and the insulation layer can also be a separate assembly structure.

[0042] In related technologies, the air conditioner's air guide plate is located inside the air vent, with its rotating part positioned at the center of its width. A gap is reserved between the circumferential end of the air guide plate and the vent wall. This allows the air guide plate to rotate freely to control the opening and closing of the air vent without interference. Currently, some air conditioners have air ducts and multiple air vents. These multiple vents, together with the air duct, form multiple air outlet channels, which are controlled by the aforementioned air guide plate and other wind-blocking components. During use, when the air guide plate closes some air vents, condensation can easily form on the closed air guide plate, causing dripping water and resulting in a poor user experience.

[0043] Research has found that in multi-air-duct air conditioners, condensation and dripping are prone to occur on the closed air guide vanes when some air vents are closed. This is because a gap exists between the circumferential end of the closed air guide vane and the wall of the closed air vent. Therefore, the air guide vane 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. 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.

[0044] Therefore, such as Figure 1 and Figure 2 As shown, in some embodiments of this application, a rotating part 231 is provided at one end of the air guide plate in the width direction, and a sealing edge 25 is provided at the circumferential end of the air guide plate. The sealing edge 25 is configured to overlap and seal with the overlapping edge of the air outlet on the outer circumferential side, so that the air guide plate closes and seals the air outlet. The air guide plate body 23 and / or the insulation layer 24 are provided with the sealing edge 25.

[0045] The air guide plate provided in this embodiment transfers the rotating part 231 of the air guide plate 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 allows the circumferential end of the air guide plate to be located outside the circumferential direction of the vent when the corresponding vent is closed (for example, the position of the air guide plate can be moved from inside the vent to the upstream or downstream side of the vent). The sealing edge 25 at the circumferential end of the air guide plate can overlap and seal with the overlapping edge of the circumferential direction of the vent, so that the corresponding vent can be completely closed. This achieves the sealing of the vent 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 occurring on the air guide plate in the closed state, and also prevents air leakage and whistling from occurring at the vent in the closed state, thereby improving the user experience.

[0046] 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.

[0047] In some exemplary embodiments, such as Figure 1As shown, a rotating part 231 is provided 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] In some exemplary embodiments, such as Figure 1 As shown, the rotating part 231 has a first connecting part 2311 and a second connecting part 2312 at its two ends. The first connecting part 2311 is configured to be connected to the driving member, and the second connecting part 2312 is configured to be rotatably connected to the supporting carrier.

[0053] The driving component can be, but is not limited to, a stepper motor. The supporting carrier can be, but is not limited to, the housing 1 of the air conditioner.

[0054] In some exemplary embodiments, such as Figure 1 As shown, 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, and is configured to be rotatably connected to the support carrier.

[0055] This provides good support for the air guide plate, helping to prevent it from deforming during use and affecting its normal operation.

[0056] like Figure 1As shown, there can be multiple third connecting parts 2313, and multiple third connecting parts 2313 are spaced apart along the length direction of the air guide plate.

[0057] In some exemplary embodiments, such as Figure 1 and Figure 2 As 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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, thereby reducing frictional resistance.

[0062] In some embodiments, the air guide plate body 23 is further provided with a partition baffle, which is located on the side of the rotating part near the insulation layer and encloses a space communicating with the clearance opening (e.g., a roughly U-shaped space). Figure 1 As shown. This effectively separates the support shaft from the insulation layer 24, allowing the material of the insulation layer 24 to flow into the sub-groove 2321 during production, without entering the clearance notch 2314 and coming into contact with the support shaft.

[0063] 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 24 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 24 and the air guide plate body 23, thereby helping to improve the connection strength.

[0064] In some exemplary embodiments, the surface of the air guide plate body 23 facing the insulation layer 24 is provided with reinforcing ribs, such as... Figure 1 As shown, this is beneficial to improving the strength of the air guide plate body 23 and also to increasing the contact area between the insulation layer 24 and the air guide plate body 23, thereby improving the connection strength.

[0065] like Figures 3 to 19 As shown, this application embodiment also provides an air conditioner, including the air guide plate of any of the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be repeated here.

[0066] 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.

[0067] In some exemplary embodiments, the air conditioner includes a housing 1 and an air guide mechanism 2.

[0068] like Figure 3 As shown, the housing 1 has an air duct 14, a first air outlet 151, and a second air outlet 152. The first air outlet 151 and the second air outlet 152 have different air outlet directions. The first air outlet 151 is configured to connect with the air duct 14 to form a first air outlet channel. The second air outlet 152 is configured to connect with the air duct 14 to form a second air outlet channel. The first air outlet 151 and the second air outlet 152 can be air outlets of an air conditioner, or they can be openings inside the air conditioner located upstream of the air outlet. Figure 11 As shown, 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.

[0069] The air guiding mechanism 2 includes multiple air guiding plates located inside the housing 1 and movably connected to the housing 1. For example... Figure 3 As shown. Multiple air guide vanes include a first air guide vane 21 and a second air guide vane 22. The first air guide vane 21 and the second air guide vane 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 where 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 (such as) where the first air outlet channel is disconnected and the second air outlet channel is open. 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] like Figure 13 and Figure 14 As 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] In some exemplary embodiments, such as Figure 4 As shown, one end of the first air guide plate 21 in the width direction is provided with a first rotating part 211 that is rotatably connected to the housing 1. The first rotating part 211 is located between the first air outlet 151 and the second sub-air outlet 1522. Figure 4 As shown, one end of the second air guide plate 22 in the width direction is provided with a second rotating part 221 that is rotatably connected to the housing 1. The second rotating part 221 is located on the side of the first sub-air outlet 1521 away from the second sub-air outlet 1522.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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).

[0090] 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.

[0091] In some embodiments, such as Figure 12 As 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.

[0092] like Figure 12 As shown, 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 for long-distance indoor air supply, which helps to improve the uniformity of indoor temperature.

[0093] 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.

[0094] 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.

[0095] like Figure 12 As shown, 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.

[0096] 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.

[0097] 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, such as... Figure 19As 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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 together form a first air outlet 151.

[0103] 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 surrounds 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. The lower end of the outer shell 11 may be open, and the outer shell 1 may also include a cover plate, which covers the open end of the outer shell 11 and has a clearance opening corresponding to and communicating with the first air outlet 151.

[0104] 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.

[0105] Of course, the first air vent 151 and the second air vent 152 can both be set on the outer casing 11.

[0106] 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.

[0107] 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 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.

[0108] 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.

[0109] 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.

[0110] like Figures 7 to 9As 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.

[0111] 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.

[0112] 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.

[0113] In the first air outlet mode, the first air guide plate 21 and the second air guide plate 22 close the second air outlet 152. The sealing edge 25 provided at the end of the first air guide plate 21 near the second air guide plate 22 is the overlapping edge of the first sub-air outlet 1521 (a type of air outlet) on the outer circumferential side. Therefore, the sealing edge 25 of the second air guide plate 22 overlaps and seals with the overlapping edge of the first sub-air outlet 1521 on the outer circumferential side. The sealing edge 25 provided at the end of the second air guide plate 22 near the first air guide plate 21 is the overlapping edge of the second sub-air outlet 1522 (a type of air outlet) on the outer circumferential side. Therefore, the sealing edge 25 of the first air guide plate 21 overlaps and seals with the overlapping edge of the second sub-air outlet 1522 on the outer circumferential side.

[0114] 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.

[0115] In some exemplary embodiments, such as Figure 3 and Figure 7As 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.

[0116] In some exemplary embodiments, 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, which leads to uneven air velocity distribution and causes a backflow zone 19 to be generated 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 a long time, condensation will form at the first air outlet 151, causing water to drip, for example, condensation will form on the inner wall of the return flow area 19, causing water to drip.

[0117] Therefore, when the current operating condition is a set condensation condition (e.g., indoor temperature greater than or equal to the first set temperature, indoor humidity greater than or equal to the set humidity, and the temperature of the indoor heat exchanger 3 of the air conditioner less than or equal to the second set temperature) and the air conditioner is in the third air outlet mode, the air outlet mode can be switched to avoid condensation at the first air outlet 151. For example, after running in the third air outlet mode for a period of time (the third set duration), it can be switched to the first air outlet mode for a period of time (the first set duration), and then switched 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 duration), 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 outlet 151.
