Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air handling equipment technology, specifically referring to an air conditioner. Background Technology

[0002] In conventional central air conditioning systems, ducted indoor units (i.e., ducted units) are typically installed recessed into the ceiling. These units usually employ centrifugal fans and have one air inlet and one air outlet, with air typically entering from the bottom and exiting from the side. However, in heating mode, the hot air cannot reach the floor, resulting in poor heating performance and a negative user experience. Utility Model Content

[0003] The technical problem to be solved by this application is to provide an air conditioner that can solve the problem that hot air cannot reach the ground in heating mode, which is beneficial to improving the user experience.

[0004] This application provides an air conditioner, including: a housing, the housing having a first air outlet and a second air outlet, one of the first air outlet and the second air outlet being a side air outlet and the other being a bottom air outlet, the width of the first air outlet being greater than the width of the second air outlet; a movable damper, one end of the movable damper having a rotating connecting portion in the width direction, the rotating connecting portion being located between the side air outlet and the bottom air outlet, and being rotatable relative to the housing, so that the movable damper can rotate between a first position of closing the bottom air outlet and a second position of closing the side air outlet; the movable damper having a first overlapping portion and a second overlapping portion, the first overlapping portion being configured to overlap with the housing when the movable damper closes the first air outlet, and the second overlapping portion being configured to overlap with the housing when the movable damper closes the second air outlet, the first overlapping portion and the second overlapping portion being staggered along the width direction of the movable damper.

[0005] The air conditioner provided in this application embodiment has a side air outlet and a bottom air outlet in its casing. The side air outlet can realize the function of side air outlet (such as front air outlet) so that the airflow can be transported over a long distance; the bottom air outlet can realize the function of bottom air outlet, which can solve the problem of blind air supply area below the duct air conditioner, so that the hot air can fall to the ground in the heating mode, thereby improving the heating effect and improving the user experience.

[0006] The movable damper can reciprocate between a first position where the lower air outlet is closed and a second position where the side air outlet is closed. When the movable damper closes the side air outlet, the lower air outlet opens, allowing the air conditioner to blow air downwards, ensuring that hot air in heating mode reaches the ground. When the movable damper closes the lower air outlet, the side air outlet opens, allowing the air conditioner to blow air laterally, enabling long-distance airflow.

[0007] The width of the first air outlet is greater than the width of the second air outlet. This allows the first outlet to be used as the main outlet and the second as an auxiliary outlet, avoiding the need for excessively large openings in the casing, which would affect aesthetics. It also prevents the need for excessively wide openings in the ceiling when installing a ducted indoor unit, thus maintaining the aesthetic appeal of the interior design. Furthermore, the design of the first and second overlapping sections improves the closing effect of the movable damper on both air outlets, reducing air leakage and thus preventing condensation and whistling.

[0008] Based on the above technical solution, the following improvements can be made to this application.

[0009] In an exemplary embodiment, the first overlapping portion and the second overlapping portion are disposed on the same side or opposite sides in the thickness direction of the movable damper.

[0010] In an exemplary embodiment, the movable damper includes a first air guide plate and a second air guide plate connected to the first air guide plate. One end of the first air guide plate in the width direction is provided with the rotating connection portion. The second air guide plate is movable relative to the first air guide plate so that the movable damper can switch between a retracted state and an unfolded state, and the movable damper can switch to the retracted state during rotation. The first overlapping portion is provided on the second air guide plate, and the second overlapping portion is provided on either the first air guide plate or the second air guide plate.

[0011] In one exemplary embodiment, based on the movable damper being in the retracted state, the width of the movable damper is adapted to the width of the second air outlet so that the movable damper can close the second air outlet; based on the movable damper being in the unfolded state, the width of the movable damper is adapted to the width of the first air outlet so that the movable damper can close the first air outlet.

[0012] In an exemplary embodiment, the first air guide plate has a storage space, and the second air guide plate is slidably connected to the first air guide plate and configured to slide relative to the first air guide plate between a storage position and an unfolded position; based on the second air guide plate sliding to the storage position, the second air guide plate is at least partially retracted into the storage space, so that the movable air damper switches to the storage state; based on the second air guide plate sliding to the unfolded position, the second air guide plate is at least partially extended out of the storage space, so that the movable air damper switches to the unfolded state.

[0013] In one exemplary embodiment, the sliding path of the second air guide plate is arc-shaped.

[0014] In an exemplary embodiment, the second air guide plate is rotatably connected to the first air guide plate and is configured to rotate relative to the first air guide plate between a retracted position and an unfolded position; based on the second air guide plate rotating to the retracted position, the second air guide plate and the first air guide plate are stacked along the thickness direction of the first air guide plate, so that the movable air damper switches to the retracted state; based on the second air guide plate rotating to the unfolded position, the second air guide plate and the first air guide plate are arranged side by side along the width direction of the first air guide plate, so that the movable air damper switches to the unfolded state.

[0015] In an exemplary embodiment, the second air guide plate is slidably connected to the first air guide plate and configured to slide relative to the first air guide plate between a retracted position and an unfolded position; based on the second air guide plate sliding to the retracted position, the second air guide plate and the first air guide plate are stacked along the thickness direction of the first air guide plate, so that the movable damper switches to the retracted state; based on the second air guide plate sliding to the unfolded position, the second air guide plate and the first air guide plate are arranged side by side along the width direction of the first air guide plate, so that the movable damper switches to the unfolded state.

[0016] In one exemplary embodiment, the width of the second air guide plate is smaller than the width of the first air guide plate.

[0017] In an exemplary embodiment, the air conditioner has a first air outlet mode, a second air outlet mode, and a third air outlet mode; based on the air conditioner being in the first air outlet mode, the movable air damper is located in the first position and in the retracted state, so that the movable air damper closes the lower air outlet and opens the side air outlet; based on the air conditioner being in the second air outlet mode, the movable air damper is located in the second position and in the unfolded state, so that the movable air damper closes the side air outlet and opens the lower air outlet; based on the air conditioner being in the third air outlet mode, the movable air damper is located in the third position, so that the movable air damper opens the side air outlet and opens the lower air outlet.

[0018] In an exemplary embodiment, based on the air conditioner being in the third air outlet mode, the movable air damper is in the retracted state; the third position is located between the first position and the second position; or, the third position coincides with the position when the movable air damper closes the first air outlet.

[0019] In an exemplary embodiment, based on the fact that the movable damper is located in the third position, the angle between the first air guide plate and the plane where the side air outlet is located is between 0° and 120°.

[0020] In one exemplary embodiment, the first air outlet is the side air outlet, and the second air outlet is the bottom air outlet. Attached Figure Description

Detailed Implementation

[0023] 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.

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

[0025] like Figures 1 to 6 As shown in the figure, this application provides an air conditioner, including: a housing 1 and a movable damper.

[0026] Among them, such as Figures 1 to 3 As shown, the housing 1 is provided with a first air outlet 11 and a second air outlet 12. One of the first air outlet 11 and the second air outlet 12 is a side air outlet 13, and the other is a bottom air outlet 14. The width of the first air outlet 11 is greater than the width of the second air outlet 12.

[0027] The movable damper has a rotating connecting part 211 at one end in the width direction. The rotating connecting part 211 is located between the side air outlet 13 and the lower air outlet 14, and can rotate relative to the housing 1 so that the movable damper can be in the first position of closing the lower air outlet 14 (e.g., Figure 2 and Figure 5 (as shown) and the second position of closing the side air outlet 13 (as shown) Figure 1 and Figure 4 Rotate between (as shown).

[0028] The movable damper has a first overlapping part 221 and a second overlapping part 213. For example... Figure 1 and Figure 4 As shown, the first overlapping part 221 is configured to overlap with the casing 1 when the movable damper closes the first air outlet 11. This improves the closing effect of the movable damper on the first air outlet 11, reduces air leakage at the first air outlet 11, and helps prevent condensation and whistling. Figure 2 and Figure 5 As shown, the second overlapping part 213 is configured to overlap with the housing 1 when the movable damper closes the second air outlet 12. This can improve the closing effect of the movable damper on the second air outlet 12, reduce the air leakage of the second air outlet 12, and help prevent condensation and whistling.

[0029] The first overlapping portion 221 and the second overlapping portion 213 are offset along the width direction of the movable damper. In other words, the first overlapping portion 221 and the second overlapping portion 213 are not exactly corresponding, but are arranged to correspond to the width of the first air outlet 11 and the second air outlet 12. The distance between the first overlapping portion 221 and the rotating connecting portion is greater than the distance between the second rotating connecting portion and the rotating connecting portion, so that the first overlapping portion 221 can overlap with the housing 1 when the movable damper closes the first air outlet 11, and the second overlapping portion 213 can overlap with the housing 1 when the movable damper closes the second air outlet 12.

[0030] The air conditioner provided in this embodiment has a casing 1 with a side air outlet 13 and a bottom air outlet 14. The side air outlet 13 can realize the function of side air outlet (e.g., front air outlet), enabling airflow to be transported over long distances. Figure 2 and Figure 5 As shown; the lower air outlet 14 can realize the lower air outlet function, which can solve the problem of blind air supply below the duct unit, so that the hot air in the heating mode can reach the ground (e.g. Figure 1 and Figure 4 As shown in the figure, this improves the heating effect and enhances the user experience.

[0031] The movable damper can reciprocate between a first position where the lower air outlet 14 is closed and a second position where the side air outlet 13 is closed. When the movable damper closes the side air outlet 13, the lower air outlet 14 is open, allowing the air conditioner to blow air downwards, ensuring that hot air in heating mode reaches the ground. When the movable damper closes the lower air outlet 14, the side air outlet 13 is open, allowing the air conditioner to blow air laterally, enabling long-distance airflow.

[0032] The width of the first air outlet 11 is greater than the width of the second air outlet 12. This allows the first air outlet 11 to be used as the main air outlet, and the second air outlet 12 as an auxiliary air outlet. This avoids having too many or too large openings in the casing 1, which would affect the aesthetics. It also prevents the need for excessively wide or large openings in the ceiling when installing a ducted indoor unit, thus maintaining the aesthetic appeal of the interior decoration. Furthermore, the design of the first and second overlapping parts improves the closing effect of the movable damper on the first and second air outlets, reducing air leakage and thus preventing condensation and whistling.

[0033] The first overlapping portion 221 can be a rigid overlapping portion, such as a plastic overlapping portion or a metal overlapping portion. Alternatively, the first overlapping portion 221 can also be a soft overlapping portion, such as a rubber overlapping portion, a silicone overlapping portion, a velvet overlapping portion, or a sponge overlapping portion. The shape of the first overlapping portion 221 is also not limited, and can be, but is not limited to, overlapping edges, overlapping surfaces, or other structural forms.

[0034] Similarly, the second overlapping part 213 can be a rigid overlapping part, such as a plastic overlapping part or a metal overlapping part. Alternatively, the first overlapping part 221 can also be a soft overlapping part, such as a rubber overlapping part, a silicone overlapping part, a velvet overlapping part, a sponge overlapping part, etc. The shape of the second overlapping part 213 is also not limited, and can be, but is not limited to, overlapping edges, overlapping surfaces, and other structural forms.

[0035] In some exemplary embodiments, the first overlapping portion 221 and the second overlapping portion 213 are disposed on the same side or opposite sides in the thickness direction of the movable damper.

[0036] In other words, the first overlapping portion 221 and the second overlapping portion 213 can be located on the same side of the thickness direction of the movable damper. Alternatively, the first overlapping portion 221 and the second overlapping portion 213 can be located on opposite sides of the thickness direction of the movable damper. The positions of the first overlapping portion 221 and the second overlapping portion 213 can be flexibly set according to the structural form of the movable damper.

[0037] In some exemplary embodiments, the movable damper includes a first air guide plate 21 and a second air guide plate 22 connected to the first air guide plate 21. The second air guide plate 22 is movable relative to the first air guide plate 21 so that the movable damper can switch between a retracted state and an extended state, allowing the movable damper to switch to the retracted state during rotation.

[0038] The movable damper can switch between a retracted state and an extended state, making its width adjustable. The movable damper can switch to the retracted state during rotation, thereby reducing the space required for rotation and preventing interference with other structures inside the air conditioner during rotation, which helps to reduce the size of the air conditioner.

[0039] The first overlapping portion 221 is located on the second air guide plate, resulting in a larger gap between the first overlapping portion 221 and the rotating connecting portion, which facilitates the closure of the wider first air outlet. The position of the second overlapping portion 213 is unrestricted; it can be located on either the first or second air guide plate. When the second overlapping portion 213 is located on the second air guide plate, it is positioned closer to the first air guide plate than the first overlapping portion 221.

[0040] In other embodiments, the movable damper may also include only one air guide plate, in which case the first overlapping part 221 and the second overlapping part 213 may be respectively disposed on both sides of the thickness direction of the movable damper.

[0041] In some exemplary embodiments, based on the active damper being in a retracted state (e.g.) Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown), the width of the movable damper is adapted to the width of the second air outlet 12 so that the movable damper can close the second air outlet 12. This is based on the movable damper being in the extended state (e.g., Figure 1 and Figure 4 As shown in the figure, the width of the movable damper is adapted to the width of the first air outlet 11 so that the movable damper can close the first air outlet 11.

[0042] The movable damper can switch between a retracted state and an extended state, and its width is adjustable. It can be adapted to the width of two air outlets to ensure that one of the two air outlets can be closed to change the airflow direction.

[0043] The width of the movable damper is adapted to the width of the first air outlet 11. This means that the distance between the two ends of the movable damper in the width direction is equal to or substantially equal to the width of the first air outlet 11, allowing the movable damper to be completely closed (for example, the distance between the two ends of the movable damper in the width direction is slightly larger than the width of the first air outlet 11, so that the two ends of the movable damper can overlap the casing 1 to completely close the first air outlet 11) or substantially close the first air outlet 11 (for example, there can be a certain gap). Similarly, the width of the movable damper is adapted to the width of the second air outlet 12. This means that the distance between the two ends of the movable damper in the width direction is equal to or substantially equal to the width of the second air outlet 12, allowing the movable damper to be completely closed (for example, the distance between the two ends of the movable damper in the width direction is slightly larger than the width of the second air outlet 12, so that the two ends of the movable damper can overlap the casing 1 to completely close the second air outlet 12) or substantially close the second air outlet 12 (for example, there can be a certain gap).

[0044] In this embodiment of the application, the air conditioner can be the indoor unit of a split air conditioner, such as a wall-mounted indoor unit, a ceiling-mounted indoor unit (such as a ducted air conditioner or a ceiling-mounted air conditioner), or a split air conditioner unit including an indoor unit and an outdoor unit, or an integrated air conditioner.

[0045] In some exemplary embodiments, such as Figures 1 to 6 As shown, the first air outlet 11 is a side air outlet 13, and the second air outlet 12 is a bottom air outlet 14. Therefore, the width of the side air outlet 13 is greater than the width of the bottom air outlet 14, which can avoid the bottom opening of the casing 1 being too large and affecting the aesthetics, and can also avoid the bottom opening of the ceiling being too wide and affecting the aesthetics of the interior decoration when the duct indoor unit is installed in the ceiling.

[0046] In other embodiments, the lower air outlet 14 is the first air outlet 11, and the side air outlet 13 is the second air outlet 12.

[0047] In some exemplary embodiments, such as Figure 2 and Figure 5 As shown, the first air guide plate 21 is adapted to the second air outlet 12. Therefore, the movable air door in the retracted state is basically equivalent to the first air guide plate 21. The opening and closing of the second air outlet 12 can be controlled by the first air guide plate 21. The opening and closing of the first air outlet 11 can be controlled by the first air guide plate 21 and the second air guide plate 22 in the unfolded state. The structure is simple.

[0048] In other embodiments, the first air guide plate 21 may not be adapted to the second air outlet 12, and the opening and closing of the second air outlet 12 may be jointly controlled by the first air guide plate 21 and the second air guide plate 22 in the retracted state.

[0049] In some exemplary embodiments, the air conditioner further includes a first drive mechanism (not shown in the figure) and a second drive mechanism (not shown in the figure). The first drive mechanism is connected to the first air guide plate 21 and is configured to drive the first air guide plate 21 to rotate. The second drive mechanism is connected to the second air guide plate 22 and is configured to drive the second air guide plate 22 to move relative to the first air guide plate 21.

[0050] The first drive mechanism may include a first drive component, which may be, but is not limited to, a motor (such as a stepper motor). The first drive component may be, but is not limited to, mounted on the housing 1. The first drive mechanism may also include a first transmission mechanism, which may be, but is not limited to, a gear transmission mechanism, a rack and pinion transmission mechanism, etc. The rotating connection part 211 may be, but is not limited to, a rotating shaft, a shaft hole, a support shaft, etc. The rotating connection part 211 is fixedly connected to the first drive mechanism. The rotating connection part 211 may also be rotatably connected to the housing 1.

[0051] The second drive mechanism may include a second drive component, which may be, but is not limited to, a motor (such as a stepper motor). The second drive mechanism may also include a second transmission mechanism, which may be, but is not limited to, a gear transmission mechanism, a rack and pinion transmission mechanism, etc. The second drive component may, but is not limited to, be mounted on the first air guide plate 21.

[0052] In some exemplary embodiments, such as Figure 1 As shown, the first air guide plate 21 has a storage space 212. The second air guide plate 22 is slidably connected to the first air guide plate 21 and is configured to slide relative to the first air guide plate 21 between a storage position and an unfolded position. At this time, the first overlapping part 221 and the second overlapping part 213 can be respectively provided on both sides of the thickness direction of the movable air door, with the first overlapping part 221 provided on the first air guide plate 21 or the second air guide plate 22, and the second overlapping part 213 provided on the second air guide plate 22.

[0053] like Figure 2 and Figure 3 As shown, based on the second air guide plate 22 sliding to the storage position, the second air guide plate 22 is at least partially retracted into the storage space 212, so that the movable air damper switches to the storage state.

[0054] like Figure 1 As shown, based on the second air guide plate 22 sliding to the unfolded position, the second air guide plate 22 extends at least partially out of the storage space 212, so that the movable air damper switches to the unfolded state.

[0055] This design achieves the switching between the retracted and extended states of the movable damper through the telescopic movement of the second air guide plate 22. Furthermore, in the retracted state, the second air guide plate 22 is at least partially hidden within the first air guide plate 21, which reduces the volume of the movable damper and helps to minimize its space requirements.

[0056] The storage space 212 can be equipped with a guide slide to guide the extension and retraction of the second air guide plate 22, making its sliding smoother.

[0057] In some embodiments, the sliding path of the first air guide plate is arc-shaped, so the first air guide plate 21 and the second air guide plate 22 can be arc-shaped air guide plates, which have a better air guiding effect. In other embodiments, the sliding path of the second air guide plate 22 can also be straight.

[0058] In other exemplary embodiments, such as Figures 4 to 6 As shown, the second air guide plate 22 is rotatably connected to the first air guide plate 21 and is configured to rotate relative to the first air guide plate 21 between the storage position and the unfolded position.

[0059] like Figure 5 and Figure 6 As shown, based on the second air guide plate 22 rotating to the storage position, the second air guide plate 22 and the first air guide plate 21 are stacked along the thickness direction of the first air guide plate 21 so that the movable air damper switches to the storage state. like Figure 4 As shown, based on the second air guide plate 22 rotating to the unfolded position, the second air guide plate 22 and the first air guide plate 21 are arranged side by side along the width direction of the first air guide plate 21 so that the movable air door switches to the unfolded state.

[0060] This solution achieves folding motion by rotating the second air guide plate 22, thereby switching between the retracted and unfolded states of the movable air door. This eliminates the need for a storage space 212 within the first air guide plate 21, which simplifies the structure of the first air guide plate 21.

[0061] At this time, the first overlapping part 221 is located on the second air guide plate 22 and in the area close to the rotation axis of the second air guide plate 22 (e.g., the end), and the second overlapping part 213 is also located on the second air guide plate 22 and in the area away from the rotation axis of the second air guide plate 22 (e.g., the end). The first overlapping part 221 and the second overlapping part 213 are located on the same side of the thickness direction of the second air guide plate 22. Therefore, it can be regarded that the first overlapping part 221 and the second overlapping part 213 are located on the same side of the thickness direction of the movable air damper (specifically the second air guide plate 22).

[0062] In some other exemplary embodiments (not shown in the figures), the second air guide plate 22 is slidably connected to the first air guide plate 21, and is configured to slide relative to the first air guide plate 21 between a stowed position and an unfolded position. In this case, the first overlapping portion 221 and the second overlapping portion 213 can be respectively disposed on both sides of the thickness direction of the movable air damper, with the first overlapping portion 221 disposed on the first air guide plate 21 or the second air guide plate 22, and the second overlapping portion 213 disposed on the second air guide plate 22.

[0063] As the second air guide plate 22 slides to the storage position, the second air guide plate 22 and the first air guide plate 21 are stacked together along the thickness direction of the first air guide plate 21 so that the movable air damper switches to the storage state.

[0064] As the second air guide plate 22 slides to the unfolded position, the second air guide plate 22 and the first air guide plate 21 are arranged side by side along the width direction of the first air guide plate 21 so that the movable air door switches to the unfolded state.

[0065] This solution achieves the folding motion by sliding the second air guide plate 22, thereby switching between the retracted and unfolded states of the movable air door. There is no need to set up a storage space 212 in the first air guide plate 21, which helps to simplify the structure of the first air guide plate 21.

[0066] In some embodiments, such as Figure 1 and Figure 4 As shown, the width of the second air guide plate 22 is smaller than the width of the first air guide plate 21, which can prevent the second air guide plate 22 from interfering with other structures inside the housing 1 after it is rotated, folded or slid.

[0067] For the second air guide plate 22 using a folding method: the first air guide plate 21 and the second air guide plate 22 can both be flat structures, then after folding, the first air guide plate 21 and the second air guide plate 22 can be a relatively regular stacked structure; the first air guide plate 21 and the second air guide plate 22 can also both be arc-shaped plate structures, then after folding, the first air guide plate 21 and the second air guide plate 22 can be a less regular stacked structure, for example, after folding, the bending direction of the first air guide plate 21 and the second air guide plate 22 can be opposite (or the same); the first air guide plate 21 and the second air guide plate 22 can also be one arc-shaped plate structure and the other flat structure, then after folding, the first air guide plate 21 and the second air guide plate 22 can also be a less regular stacked structure.

[0068] In some exemplary embodiments, the air conditioner has a first air outlet mode, a second air outlet mode, and a third air outlet mode.

[0069] Based on the air conditioner being in the first air outlet mode (such as...) Figure 2 and Figure 5 As shown), the movable damper is in the first position and in a retracted state, so that the movable damper closes the lower air outlet 14 and opens the side air outlet 13.

[0070] Based on the air conditioner being in the second air outlet mode (such as...) Figure 1 and Figure 4 As shown), the movable damper is in the second position and in the open state, so that the movable damper closes the side air outlet 13 and opens the lower air outlet 14.

[0071] Based on the air conditioner being in the third air outlet mode (such as...) Figure 3 and Figure 6 As shown), the movable damper is in the third position so that the movable damper opens the side air outlet 13 and the lower air outlet 14.

[0072] Therefore, the air conditioner has three air outlet modes: side air outlet mode (i.e., the first air outlet mode), bottom air outlet mode (i.e., the second air outlet mode), and dual air outlet mode (i.e., the third air outlet mode). When the user needs rapid cooling or rapid heating, they can select the second air outlet mode, in which the airflow is discharged downwards through the bottom air outlet 14, facilitating a rapid decrease or increase in temperature in the area below. When the user wants to avoid direct airflow, they can select the first air outlet mode, in which the airflow is discharged laterally through the side air outlet 13, facilitating long-distance airflow and avoiding direct airflow to the user. When the user wants uniform cooling or heating throughout the entire area, they can select the third air outlet mode, in which the airflow is blown out together through the side air outlet 13 and the bottom air outlet 14, which can quickly adjust the temperature of the nearby area below and also deliver air over a long distance, enabling rapid temperature adjustment in areas further away.

[0073] In some embodiments, based on the air conditioner being in the third air outlet mode, the movable air damper is in a retracted state, such as... Figure 3 and Figure 6 As shown. This reduces the width of the movable damper, which helps to avoid interference between the movable damper and heat exchanger 3. Of course, the movable damper can also be in the extended state.

[0074] In some embodiments, the third position is located between the first position and the second position, such as... Figure 3 and Figure 6 As shown. In this way, the movable damper can divide the airflow into two paths, so that the two airflows can flow to the side air outlet 13 and the bottom air outlet 14 respectively.

[0075] Of course, the third position coincides with the position when the movable damper closes the first air outlet 11. Since the movable damper is in the retracted state at this time and cannot close the first air outlet 11, both the first air outlet 11 and the second air outlet 12 can emit air to achieve the dual air outlet mode.

[0076] In some embodiments, based on the movable damper being in the third position, the angle α between the first air guide plate 21 and the plane containing the side air outlet 13 (e.g.) Figure 3 (As shown) The angle can be between 0° and 120°, such as 0°, 30°, 45°, 60°, 90°, 120°, etc. Experiments have verified that this allows the dual-outlet mode to achieve better performance.

[0077] The cross-section of the air guiding portion of the first air guide plate 21 can be, but is not limited to, an arc shape. The angle between the first air guide plate 21 and the plane where the side air outlet 13 is located can be defined as the angle between the tangent of the middle part of the surface of the first air guide plate 21 away from the lower air outlet 14 and the vertical plane (or defined as the angle between the tangent of the end of the surface of the first air guide plate 21 away from the lower air outlet 14 near the axis of rotation of the first air guide plate 21 and the vertical plane).

[0078] In other embodiments, the width of the first air outlet 11 may also be equal to the width of the second air outlet 12. The movable damper can be in the unfolded state when closing the first air outlet 11 and the second air outlet 12, and in the retracted state during rotation. It can switch to the unfolded state when reaching the first or second position, and is also in the retracted state when in the third position.

[0079] In some exemplary embodiments, the air conditioner may operate according to the following logic: When cooling mode is activated, the air conditioner automatically recognizes parameters and defaults to rapid cooling mode. At this time, the side air outlet 13 is closed, and the bottom air outlet 14 is open. Pressing the air outlet button allows cold air to quickly reach the ground. The movable air damper is in the second position and in the extended state. After running continuously for t1 minutes, the bottom air outlet 14 closes, the side air outlet 13 opens, and the movable air damper is in the first position and in the retracted state. The air conditioner continues to operate in the side air outlet mode to prevent cold air from continuing to blow on people.

[0080] When the air conditioner is in cooling mode, it automatically identifies the parameters. If it detects that the user has selected the normal cooling mode, it will operate in the side air outlet mode. At this time, the movable air damper is in the first position and in the retracted state.

[0081] When the air conditioner is in cooling mode, it automatically identifies the parameters and recognizes that the user has selected the whole-area cooling mode. It then operates in dual-airflow mode, with the movable air damper in the third position and in a retracted state, achieving whole-area air supply throughout the house.

[0082] When in heating mode, the air conditioner automatically recognizes the parameters and defaults to rapid heating mode. At this time, the side air outlet 13 is closed and the lower air outlet 14 is open. Press the air outlet mode button to operate, and the movable damper is in the second position and in the open state. After running continuously for t2 minutes, the lower air outlet 14 remains open, the side air outlet 13 is open, and the movable damper is in the third position and in the retracted state. Press the dual air outlet mode button to continue operating.

[0083] When in heating mode, the air conditioner automatically recognizes the parameters and detects that the user has selected the normal heating mode. It then operates with the side air outlet in the first position and is in the retracted state.

[0084] When in heating mode, the air conditioner automatically identifies parameters and recognizes that the user has selected the whole-area heating mode. It then operates in dual-airflow mode, with the movable air damper in the third position and in a retracted state, achieving whole-area air supply throughout the house to meet the heating needs of different groups of people.

[0085] This air conditioner allows the hot air from the ducted indoor unit to effectively reach the ground in heating mode, and can provide multi-directional, all-area airflow according to user needs; it also features fast cooling / heating speed, a compact structure, and a wide cooling / heating airflow coverage area, which can be freely selected according to user needs.
