Description

Technical Field

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

[0002] In standard central air vent modules, ducted indoor units (i.e., ducted air conditioners) are typically installed in the ceiling. These indoor units usually use centrifugal fans and have one air inlet and one air outlet, typically with air intake at the bottom and exhaust at 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 outlet module and 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 outlet module, including: an air outlet housing with a side air outlet and a lower air outlet, the side air outlet including a first sub-air outlet; and a first air guide plate, one end of the first air guide plate in the width direction having a first rotating connection portion, the first rotating connection portion being located between the first sub-air outlet and the lower air outlet, and being rotatable relative to the air outlet housing, so that the first air guide plate can rotate between a first position of closing the lower air outlet and a second position of closing the first sub-air outlet, and the rotation axis of the first air guide plate is higher than the end of the lower air outlet away from the first rotating connection portion; and a second air guide plate, disposed at the side air outlet and located below the first air guide plate, configured to guide the airflow flowing through it.

[0005] The air outlet module provided in this application embodiment can be applied to an air conditioner. Its air outlet housing is provided with a side air outlet and a bottom air outlet. 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 air duct unit, 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 first air guide plate can rotate between a first position where the lower air outlet is closed and a second position where the first sub-air outlet is closed. When the first air guide plate closes the first sub-air outlet, the lower air outlet opens, allowing the air outlet module to discharge air downwards, ensuring that hot air in heating mode reaches the ground. When the first air guide plate closes the lower air outlet, the first sub-air outlet opens, allowing the air outlet module to discharge air laterally, enabling long-distance airflow. Furthermore, the opening and closing of the first sub-air outlet and the lower air outlet can be controlled using only the first air guide plate, resulting in a simple structure that helps reduce production costs and simplifies the electrical control program.

[0007] Furthermore, the rotation axis of the first air guide plate is positioned higher than the end of the lower air outlet furthest from the first rotating connection. Therefore, the first air guide plate is in an inclined state when the lower air outlet is closed, rather than a horizontal state; thus, the lower air outlet is an inclined opening. Given a consistent width in the horizontal direction, the inclined lower air outlet has a larger area than a horizontally positioned lower air outlet, which helps to increase the airflow from the lower air outlet.

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

[0015] In an exemplary embodiment, the second air guide plate is an arc-shaped air guide plate, and the second air guide plate is configured to rotate between a fourth position where the second sub-air vent is closed and a fifth position where the second sub-air vent is open; based on the second air guide plate being located in the fourth position, the outer convex surface of the second air guide plate faces the downstream side of the air outlet housing.

[0016] In one exemplary embodiment, the second air guide plate is configured to overlap with the first air guide plate so that the side air outlet can be closed.

[0029] 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.

[0030] like Figures 1 to 6 As shown, this application embodiment provides an air vent module 100 and an air conditioner including the air vent module 100.

[0031] The air outlet module 100 includes: an air outlet housing 102 (such as...) Figure 10 (As shown), the first air guide plate 21 and the second air guide plate 22. The air conditioner also includes a main casing 104, a fan 3, a heat exchanger 4, and other structures. The main casing 104 and the air outlet casing 102 are detachably or non-detachably connected to form the air conditioner casing 1. When the main casing 104 and the air outlet casing 102 are detachably connected, the air outlet module 100 is a detachable module. When the main casing 104 and the air outlet casing 102 are non-detachably connected (e.g., integrally formed), the air outlet module 100 is a non-detachable module.

[0032] Among them, such as Figures 1 to 6 As shown, the air outlet housing 102 is provided with a side air outlet and a bottom air outlet 13. The side air outlet includes a first sub-air outlet 11.

[0033] The first air guide plate 21 has a first rotating connection at one end in the width direction. The first rotating connection is located between the first sub-air outlet 11 and the lower air outlet 13, and can rotate relative to the air outlet housing 102, so that the first air guide plate 21 can rotate between a first position with the lower air outlet 13 closed and a second position with the first sub-air outlet 11 closed, and the position of the rotation axis of the first air guide plate 21 is higher than the end of the lower air outlet 13 away from the first rotating connection.

[0034] The second air guide plate 22 is located at the side air outlet and below the first air guide plate 21, and is configured to guide the airflow passing through it.

[0035] The air outlet module 100 and air conditioner provided in this application embodiment have a side air outlet and a bottom air outlet 13 on their air outlet housing 102. 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. Figure 2 and Figure 5 As shown; the lower air outlet 13 can realize the lower air outlet function (such as... Figure 1 and Figure 4 As shown in the figure, this can solve the problem of blind spots in air supply below the ducted air conditioner, allowing hot air to fall to the ground in heating mode, thereby improving the heating effect and enhancing the user experience.

[0036] The first air guide plate 21 can rotate between a first position where the lower air outlet 13 is closed and a second position where the first sub-air outlet 11 is closed. When the first air guide plate 21 closes the first sub-air outlet 11, the lower air outlet 13 opens, and the air outlet module can discharge air downwards, allowing hot air in heating mode to reach the ground, such as... Figure 1 and Figure 4 As shown. When the first air guide plate 21 closes the lower air outlet 13, the first sub-air outlet 11 opens, allowing the air outlet module to discharge air laterally, enabling long-distance airflow delivery, such as... Figure 2 and Figure 5 As shown. Furthermore, the opening and closing of the first sub-air outlet 11 and the lower air outlet 13 can be controlled by the first air guide plate 21. The structure is simple, which helps to reduce production costs and simplify the electrical control program.

[0037] Furthermore, the rotation axis of the first air guide plate 21 is positioned higher than the end of the lower air outlet 13 that is furthest from the first rotating connection portion, such as... Figures 1 to 6As shown. Therefore, when the first air guide plate 21 closes the lower air outlet 13, it is in an inclined state, not a horizontal state, so the lower air outlet 13 is an inclined opening. With a consistent width in the horizontal direction, the inclined lower air outlet 13 has a larger area than the horizontally set lower air outlet 13, which is beneficial to increasing the air volume of the lower air outlet 13.

[0038] The air outlet housing 102 can be provided with a lower air outlet channel. The upper port of the lower air outlet channel is the lower air outlet 13. The lower port of the lower air outlet channel can be set horizontally, so the appearance structure of the air outlet housing 102 is relatively regular.

[0039] 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, a ceiling-mounted air conditioner, etc.), or a split air conditioner unit including an indoor unit and an outdoor unit, or an integrated air conditioner.

[0040] The first sub-air outlet 11 can be an air outlet inside the housing 1 or an air outlet on the side wall of the housing 1. The first air guiding mechanism controls the opening and closing of the first sub-air outlet 11. This opening and closing is broad in the sense that the first air guiding mechanism is considered to be open as long as it can control the air duct (referred to as the first side air outlet channel) connected to the first sub-air outlet 11 within the air outlet cavity 18 to be open, and it is considered to be closed as long as it can control the first side air outlet channel to be closed. It is not required that the first air guiding mechanism have a damper located exactly at the first sub-air outlet 11 and whose size is exactly matched to the first sub-air outlet 11. The width of the air outlet opening located on the downstream side of the housing 1 (such as the width of the side air outlet flange) can be the same as or different from the width of the side air outlet.

[0041] Similarly, the lower air outlet 13 can be an air outlet inside the housing 1 or an air outlet on the bottom wall of the housing 1. The first air guiding mechanism controls the opening and closing of the lower air outlet 13 in a broad sense. As long as the first air guiding mechanism can control the air duct (hereinafter referred to as the lower air outlet channel) connected to the lower air outlet 13 in the air outlet cavity 18 to be open, it is considered that the lower air outlet 13 is open. As long as the air guiding mechanism can control the lower air outlet channel to be disconnected, it is considered that the lower air outlet 13 is closed. It is not required that the air guiding mechanism have a damper that is exactly located at the lower air outlet 13 and exactly matches the size of the lower air outlet 13. The width of the air outlet opening at the bottom of the housing 1 at the lowest downstream side (such as the width of the lower air outlet flange) can be the same as or different from the width of the lower air outlet 13.

[0042] In some exemplary embodiments, such as Figure 2As shown, the main body 104 of the air conditioner has an inlet heat exchange chamber 17, and the outlet housing 102 has an outlet chamber 18 that communicates with the inlet heat exchange chamber 17. The inlet heat exchange chamber 17 houses a fan 3 and a heat exchanger 4, with the heat exchanger 4 located downstream of the fan 3. The fan 3 is a centrifugal fan. The length of the inlet heat exchange chamber 17 in the air outlet direction (i.e., the arrangement direction of the inlet heat exchange chamber 17 and the outlet chamber 18, i.e., the front-to-back direction) is denoted as L1, and the length of the outlet chamber 18 in the air outlet direction is denoted as L2. L1 + L2 ≤ 580 mm, facilitating the installation of the main body of the air conditioner within the ceiling. An outlet flange can also be installed at the side outlet. The length L2 of the outlet chamber 18 does not include the length of the outlet flange in the air outlet direction.

[0043] In some exemplary embodiments, the second air guide plate 22 is a fixed air guide plate, please refer to the following: Figure 4 , Figure 5 and Figure 8 As shown. In other words, there are two air guide vanes, one movable and the other fixed, which simplifies the structure and electrical control program of the air outlet module. Figure 8 In the middle, the second air guide plate 22 is a fixed air guide plate, and the air conditioner is in the third air outlet mode; when the air conditioner is in the first air outlet mode, the positions of the two air guide plates are the same as those of the first air outlet mode. Figure 5 The structures are similar; when the air conditioner is in the second air outlet mode, the positions of the two air guides are similar to... Figure 4 Their structures are similar.

[0044] exist Figure 4 In the middle, the air conditioner is in the downward air outlet mode; Figure 5 The air conditioner is in side-venting mode; Figure 8 In the middle, the air conditioner is in dual air outlet mode. Switching between the three air outlet modes is achieved by rotating the first air guide plate 21.

[0045] In other exemplary embodiments, such as Figures 4 to 6 As shown, the side air outlet also includes a second sub-air outlet 12 arranged side by side with the first sub-air outlet 11. The second sub-air outlet 12 is located below the first sub-air outlet 11. The second air guide plate is a movable air guide plate, which is configured to control the opening and closing of the second sub-air outlet 12.

[0046] In other words, both air guides are movable, and the opening and closing of the second sub-air outlet 12 can be controlled independently by the second air guide 22. This allows for effective control of the opening and closing of both the side air outlet and the lower air outlet 13, facilitating the selection of the appropriate airflow mode according to user needs. Furthermore, the design of the second sub-air outlet 12 increases the total width of the side air outlets of the air outlet module, which is beneficial for increasing the airflow volume during side airflow.

[0047] The second sub-air vent 12 can be an air vent inside the housing 1 or an air outlet on the side wall of the housing 1. The second air guiding mechanism controls the opening and closing of the second sub-air vent 12 in a broad sense. As long as the second air guiding mechanism can control the air duct (hereinafter referred to as the second side air outlet channel) connected to the second sub-air vent 12 in the air outlet cavity 18 to be open, it is considered that the second sub-air vent 12 is open. As long as the second air guiding mechanism can control the second side air outlet channel to be disconnected, it is considered that the second sub-air vent 12 is closed. It is not required that the second air guiding mechanism have a damper that is exactly located at the second sub-air vent 12 and whose size is exactly matched with the second sub-air vent 12.

[0048] In some exemplary embodiments, the second sub-vent 12 is connected to the first sub-vent 11, forming an opening that facilitates the processing and shaping of the air outlet housing 102.

[0049] In some exemplary embodiments, the second air guide plate 22 is provided with a second rotating connecting portion, which is coaxially arranged with the first rotating connecting portion, such as... Figures 4 to 6 As shown. At this time, the second rotating connection part is located at the end of the second air guide plate 22 near the first sub-air outlet 11. In this way, when the first air guide plate 21 and the second air guide plate 22 are both supported on the air outlet housing 102, they can be supported at the same part of the air outlet housing 102 to simplify the structure of the air outlet housing 102, and even the first air guide plate 21 and the second air guide plate 22 can be driven by the same drive mechanism to simplify the air outlet module structure.

[0050] In other embodiments, the second rotating connection portion and the first rotating connection portion may also be arranged on different axes, such as parallel and spaced apart. Figures 1 to 3 As shown. At this time, the second rotating connection part can be provided at the end of the second air guide plate 22 away from the first sub-air outlet 11 or between the two ends in the width direction of the second air guide plate 22.

[0051] The specific locations of the first and second rotating connecting parts can be reasonably set according to needs. For example, based on the fact that the second rotating connecting part is coaxial with the first rotating connecting part, the first and second rotating connecting parts are located on the side wall of the air outlet cavity 18 away from the air inlet heat exchange cavity 17, such as... Figures 4 to 6 As shown.

[0052] Alternatively, the second rotating connecting part can be coaxially arranged with the first rotating connecting part, and both the first and second rotating connecting parts can be located within the air outlet cavity 18, such as... Figure 9 As shown. Figure 9 The dashed lines indicate other working positions of the first air guide plate, and the dotted lines indicate other working positions of the second air guide plate.

[0053] Alternatively, the second rotating connection portion can be arranged parallel to and spaced apart from the first rotating connection portion, with the first rotating connection portion located inside the air outlet cavity 18 and the second rotating connection portion located on the side wall of the air outlet cavity 18 away from the air inlet heat exchange cavity 17, such as... Figures 1 to 3 As shown.

[0054] In some exemplary embodiments, such as Figure 7 As shown, the first rotating connecting part includes a first rotating shaft 211, and the second rotating connecting part includes a second rotating shaft 221. At least one of the first rotating shaft 211 and the second rotating shaft 221 is a hollow shaft, so that the first rotating shaft 211 and the second rotating shaft 221 can be nested together. The air vent module also includes a first driving mechanism (not shown in the figure) and a second driving mechanism (not shown in the figure). The first driving mechanism is connected to the first rotating shaft 211 and is configured to drive the first rotating shaft 211 to rotate. The second driving mechanism is connected to the second rotating shaft 221 and is configured to drive the second rotating shaft 221 to rotate.

[0055] In this way, the rotation of the first air guide plate 21 and the second air guide plate 22 is independent of each other, and the rotation direction and rotation amplitude of the first air guide plate 21 and the second air guide plate 22 can be reasonably controlled as needed.

[0056] In some exemplary embodiments, such as Figure 7 As shown, the first air guide plate 21 is also provided with a first support part 212 connected to the first rotating shaft 211, and the second air guide plate 22 is also provided with a second support part 222 connected to the second rotating shaft 221. The first support part 212 and the second support part 222 are staggered along the axial direction of the first rotating shaft 211.

[0057] The hollow shaft may have a notch so that the rotating shaft located inside it can be connected to the structure outside the hollow shaft (such as the first support 212 / second support 222, or the air outlet housing 102, or the first drive mechanism / second drive mechanism).

[0058] The first rotating shaft 211 and the first support part 212 can be a separate assembly structure (i.e., they are processed and formed separately and then assembled together, such as by snap-fit ​​connection, fastener connection, or bonding). The second rotating shaft 221 and the second support part 222 can also be a separate assembly structure (such as by snap-fit ​​connection, fastener connection, or bonding). This facilitates nesting the first rotating shaft 211 and the second rotating shaft 221, and then connecting them to the first support part 212 and the second support part 222 respectively. The air guide body of the first support part 212 and the first air guide plate 21 can be an integrated structure or a separate assembly structure. The air guide body of the second support part 222 and the second air guide plate 22 can be an integrated structure or a separate assembly structure.

[0059] The first support portion 212 can be a block structure with a shaft hole or a C-shaped groove, and the first rotating shaft 211 passes through the shaft hole or C-shaped groove of the first support portion 212. The second support portion 222 can be a block structure with a shaft hole or a C-shaped groove, and the second rotating shaft 221 passes through the shaft hole or C-shaped groove of the second support portion 222.

[0060] like Figure 7 As shown, there can be multiple first support portions 212, which can be spaced apart along the axial direction of the first rotating shaft 211. There can also be multiple second support portions 222, which can be spaced apart along the axial direction of the second rotating shaft 221. The multiple first support portions 212 and the multiple second support portions 222 can be staggered. Alternatively, the multiple first support portions 212 can be divided into two groups, with the multiple second support portions 222 located between the two groups of first support portions 212. Or, the multiple second support portions 222 can be divided into two groups, with the multiple first support portions 212 located between the two groups of second support portions 222.

[0061] 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 air outlet housing 102. 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 first rotating shaft 211 is fixedly connected to the first drive mechanism. The first rotating shaft 211 may also be rotatably connected to the air outlet housing 102.

[0062] 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 component may be, but is not limited to, mounted on the air outlet housing 102. 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 rotating shaft 221 is fixedly connected to the second drive mechanism. The second rotating shaft 221 may also be rotatably connected to the air outlet housing 102.

[0063] In some exemplary embodiments, the first drive mechanism and the second drive mechanism are axially spaced on both sides of the first sub-air outlet 11 along the first rotating shaft 211. One end of the first rotating shaft 211 is connected to the first drive mechanism, and the other end is rotatably connected to the air outlet housing 102. One end of the second rotating shaft 221 is connected to the second drive mechanism, and the other end is rotatably connected to the air outlet housing 102.

[0064] The first rotating shaft 211, at one end connected to the first driving mechanism, can protrude beyond the second rotating shaft 221 for connection to the first driving mechanism. The second rotating shaft 221, at one end connected to the second driving mechanism, can protrude beyond the first rotating shaft 211 for connection to the second driving mechanism.

[0065] The air outlet housing 102 may be provided with a first shaft hole and a second shaft hole, and the two ends of the hollow shaft are respectively inserted into the first shaft hole and the second shaft hole, so as to realize the rotatable connection between the first rotating shaft 211 and the second rotating shaft 221 and the air outlet housing 102.

[0066] In some exemplary embodiments, the second air guide plate 22 is configured in a fourth position after the second sub-air outlet 12 is closed (e.g., Figure 4 and Figure 5 (as shown) and the fifth position of opening the second sub-vent 12 (as shown) Figure 6 The second air guide plate 22 rotates between the fourth and fifth positions (as shown). Furthermore, from the fourth position to the fifth position, the second air guide plate 22 rotates towards the upstream side of the air outlet housing 102 (i.e., the inner side of the housing 1), in conjunction with... Figures 4 to 6 It can be known that...

[0067] This avoids the second air guide plate 22 occupying the space outside the casing 1 during rotation, which helps to reduce the depth requirement when the ducted air conditioner is installed in the ceiling. Furthermore, when the second air guide plate 22 rotates to the fifth position, it can also act as a duct wall to guide the airflow, making it easier to guide the airflow to the second sub-air outlet 12.

[0068] Of course, from the fourth position to the fifth position, the second air guide plate 22 can also rotate to the downstream side of the air outlet housing 102 (i.e., the outer side of the housing).

[0069] In other embodiments, the first rotating shaft 211 and the second rotating shaft 221 are coaxially arranged, and the first rotating shaft 211 and the second rotating shaft 221 are fixedly connected or in a limiting engagement. For example, one of the first rotating shaft 211 and the second rotating shaft 221 has a non-cylindrical limiting groove, and the other has a non-cylindrical limiting protrusion. The limiting protrusion is inserted into the limiting groove to limit the engagement of the first rotating shaft 211 and the second rotating shaft 221 and allow them to rotate synchronously. Alternatively, the first rotating shaft 211 and the second rotating shaft 221 are fixedly connected together by means of clamps, bushings, fasteners, integral molding, etc., to achieve synchronous rotation.

[0070] The air vent module also includes a drive mechanism, which is connected to the first rotating shaft 211 or the second rotating shaft 221 and is configured to drive the first rotating shaft 211 and the second rotating shaft 221 to rotate synchronously.

[0071] In other words, the first air guide plate 21 and the second air guide plate 22 can also be connected through the same drive mechanism, so the rotation direction (clockwise or counterclockwise) of the first air guide plate 21 and the second air guide plate 22 is the same. When the first air guide plate 21 rotates to the first position to close the lower air outlet 13, the second air guide plate 22 turns outward from the air outlet housing 102 to open the second sub-air outlet 12, thereby realizing the side air outlet mode (the first air guide plate 21 has rotated to the first position) and the dual air outlet mode (the first air guide plate 21 has not yet rotated to the first position). When the first air guide plate 21 rotates to the second position to close the first sub-air outlet 11, the second air guide plate 22 rotates inward from the air outlet housing 102 to close the second sub-air outlet 12, thereby realizing the lower air outlet mode.

[0072] In some exemplary embodiments, the second air guide plate 22 is an arc-shaped air guide plate. Since the second air guide plate 22 is located in the fourth position, its convex surface faces the downstream side of the air outlet housing 102, as shown below. Figure 4 and Figure 5 As shown.

[0073] In this way, when the second air guide plate 22 rotates to the fourth position, the second air guide plate 22 can also act as a duct wall to guide the airflow and facilitate the airflow to flow to the lower air outlet 13.

[0074] In some exemplary embodiments, the first air guide plate 21 is an arc-shaped air guide plate. Based on the fact that the first air guide plate 21 is located in the second position, the convex surface of the first air guide plate 21 faces the downstream side of the air outlet housing 102, such as... Figure 1 and Figure 4 As shown.

[0075] In this way, when the first air guide plate 21 rotates to the second position, the first air guide plate 21 can also act as a duct wall to guide the airflow and facilitate the airflow to flow to the lower air outlet 13.

[0076] In some exemplary embodiments, the second air guide plate 22 is configured to overlap with the first air guide plate 21 so that the side air outlet can be closed, such as... Figure 1 As shown.

[0077] In other words, regardless of whether the second air guide plate 22 is a fixed air guide plate or a movable air guide plate, the second air guide plate 22 can overlap and cooperate with the first air guide plate 21, so that the side air outlet can be closed, thereby realizing the bottom air outlet mode, which facilitates rapid cooling and rapid heating. Furthermore, the overlap between the second air guide plate 22 and the first air guide plate 21 can reduce the air leakage in the bottom air outlet mode, which is beneficial for preventing condensation and whistling.

[0078] In some exemplary embodiments, the air conditioner has a first air outlet mode, a second air outlet mode, and a third air outlet mode. Accordingly, the air vent module 100 has a first air outlet mode, a second air outlet mode, and a third air outlet mode.

[0079] Based on the air outlet module being in the first air outlet mode (e.g.) Figure 2 and Figure 5 As shown), the lower air outlet 13 is closed, and the side air outlet is opened (the opening range is not limited; for example, only the first sub-air outlet 11 can be opened, or both the first sub-air outlet 11 and the second sub-air outlet 12 can be opened). The first air guide plate 21 is in the first position. When the second air guide plate 22 is a movable air guide plate, the first air guide plate 21 is in the first position to open the first sub-air outlet 11 and close the lower air outlet 13. The second air guide plate 22 is in the fourth position to close the second sub-air outlet 12 (for example, in a scheme where the first rotating shaft 211 and the second rotating shaft 221 rotate independently) or in the fifth position to open the second sub-air outlet 12 (for example, in a scheme where the first rotating shaft 211 and the second rotating shaft 221 rotate synchronously). When the second air guide plate 22 is a fixed air guide plate, the first air guide plate 21 opens the first sub-air outlet 11 and closes the lower air outlet 13.

[0080] Based on the air outlet module being in the second air outlet mode (e.g.) Figure 1 and Figure 4 As shown), the lower air outlet 13 is opened, the side air outlet is closed, and the first air guide plate 21 is in the second position. When the second air guide plate 22 is a movable air guide plate, the first air guide plate 21 is in the second position to close the first sub-air outlet 11 and open the lower air outlet 13, and the second air guide plate 22 is in the fourth position to close the second sub-air outlet 12. When the second air guide plate 22 is a fixed air guide plate, the first air guide plate 21 closes the first sub-air outlet 11 and overlaps with the second air guide plate 22.

[0081] Based on the air outlet module being in the third air outlet mode (e.g.) Figure 3 , Figure 6 and Figure 8 As shown), both the lower air outlet 13 and the side air outlet are open, and the first air guide plate 21 is located in the third position between the first and second positions. When the second air guide plate 22 is a movable air guide plate, the first air guide plate 21 is located in the third position with the first sub-air outlet 11 and the lower air outlet 13 open, and the second air guide plate 22 is located in the fifth position with the second sub-air outlet 12 open (for example, in the case where the first rotating shaft 211 and the second rotating shaft 221 rotate independently) or in the fourth position with the second sub-air outlet 12 closed (for example, in the case where the first rotating shaft 211 and the second rotating shaft 221 rotate synchronously). When the second air guide plate 22 is a fixed air guide plate, the first air guide plate 21 opens the first sub-air outlet 11 and the lower air outlet 13 and is spaced apart from the second air guide plate 22.

[0082] Therefore, the air outlet module 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, the second air outlet mode can be selected, in which the airflow is discharged downward through the bottom air outlet 13, facilitating a rapid decrease or increase in temperature in the area below. When the user wants to avoid direct airflow, the first air outlet mode can be selected, in which the airflow is discharged laterally through the first sub-air outlet 11, facilitating long-distance airflow and avoiding direct airflow to the user. When the user wants uniform cooling or heating throughout the entire area, the third air outlet mode can be selected, in which the airflow is blown out together through the first sub-air outlet 11, the second sub-air outlet 12, and the bottom air outlet 13, which can quickly adjust the temperature of the nearby area below and also deliver air over a long distance, enabling rapid temperature adjustment in distant areas as well.

[0083] In some exemplary embodiments, based on the fact that the second air guide plate 22 is a movable air guide plate and the second rotating connection portion of the second air guide plate 22 is coaxially arranged with the first rotating connection portion, the first air guide plate 21 and the second air guide plate 22 rotate towards each other during the process of the air conditioner switching from the second air outlet mode to the third air outlet mode.

[0084] Please refer to this as well. Figure 4 and Figure 6 As shown, during the process of the air conditioner switching from the second air outlet mode to the third air outlet mode, the first air guide plate 21 rotates clockwise toward the inside of the housing 1, and the second air guide plate 22 rotates counterclockwise toward the inside of the housing 1. Therefore, the first air guide plate 21 and the second air guide plate 22 rotate toward each other.

[0085] In this way, the movable space of the first air guide plate 21 and the second air guide plate 22 is located on the same side of their rotation axis, and they can share the movable space, which is beneficial to reducing the depth of the air outlet cavity 18. Furthermore, the first air guide plate 21 and the second air guide plate 22 can be rotated to a position where they just touch. At this time, the first air guide plate 21 and the second air guide plate 22 can divide the internal space of the air outlet cavity 18 into two channels, so that part of the airflow flows along the first air guide plate 21 to the first sub-air outlet 11, and the other part of the airflow flows along the second air guide plate 22 to the second sub-air outlet 12 and the lower air outlet 13.

[0086] In some exemplary embodiments, the first air guide plate 21 can be an arc-shaped air guide plate so that both sides of the first air guide plate 21 can be used as air duct walls. The second air guide plate 22 is an arc-shaped air guide plate so that at least one side of the second air guide plate 22 can be used as an air duct wall. When the second air guide plate 22 is a fixed air guide plate, only one side of the plate can be used as an air duct wall. When the second air guide plate 22 is a movable air guide plate, both sides of the plate can be used as air duct walls.

[0087] Both the first air guide plate 21 and the second air guide plate 22 are arc-shaped air guide plates, which can be used as air duct walls to play a good air guiding role, which helps to reduce wind resistance and increase air volume.

[0088] In some exemplary embodiments, based on the side air outlet being closed (i.e., the air conditioner being in the second air outlet mode), the surface of the first air guide plate 21 facing the upstream side of the air outlet housing 102 is denoted as the first curved surface 213, such as... Figure 1 As shown, the surface of the second air guide plate 22 facing the upstream side of the air outlet housing 102 is designated as the second curved surface 223, and the first curved surface 213 is adjacent to the second curved surface 223. In other words, the first curved surface 213 and / or the second curved surface 223 are configured to face the air outlet of the fan 3 blowing air towards the air outlet module 100.

[0089] The air outlet of the fan 3 faces the first curved surface 213 and / or the second curved surface 223.

[0090] In this way, when the airflow blown by the fan 3 flows towards the first guide plate 21, part of it continues along the first guide plate 21 to the second guide plate 22, while the other part is diverted and flows directly to the lower air outlet 13. When the airflow blown by the fan 3 flows towards the second guide plate 22, part of it continues along the second guide plate 22, while the other part is diverted and flows directly to the lower air outlet 13. This improves the uniformity of airflow from the lower air outlet 13.

[0091] The first surface 213 and the second surface 223 can both be circular arc surfaces, and their curvature can be the same or different.

[0092] In some exemplary embodiments, the tangent at the end of the first curved surface 213 intersects the second curved surface 223. Therefore, the air flowing out from the tangent at the end of the first curved surface 213 is further guided by the second curved surface 223. This portion of air is buffered and flows in two directions at the end of the second curved surface 223, resulting in very low noise from the air wake at the end of the second curved surface 223. Furthermore, when the air flows on both curved surfaces, a portion of the air is discharged vertically towards the lower air outlet 13, resulting in more uniform downward airflow.

[0093] In some exemplary embodiments, at least one of the first surface 213 and the second surface 223 is configured as a fastest curve surface that fits the fastest curve.

[0094] The shortest distance between two points is a straight line, but the fastest path between two points is a curve. For example, imagine two tracks on an inclined plane: one straight, the other curved, with the same starting and ending heights. Two balls of the same mass and size slide down from the starting point simultaneously; the ball on the curved track will reach the ending point first. Among many curves, the brachistochrone curve allows the ball to reach the ending point the fastest. The brachistochrone curve is a cycloid, which is the trajectory formed by a fixed point on a circle moving along a straight line. Furthermore, objects with different initial coordinates can reach the ending point at the same moment when sliding down the same brachistochrone curve. The surface that fits the brachistochrone curve is called the brachistochrone surface.

[0095] When at least one of the first surface 213 and the second surface 223 is constructed as a fastest curve that fits the fastest curve, the air blown onto the first surface 213 / second surface 223 can flow rapidly to the lower air outlet 13, thereby increasing the air outlet speed.

[0096] In some exemplary embodiments, at least one of the first surface 213 and the second surface 223 is concave. The concave surface can enhance the wall adhesion effect of the airflow, making it easier to guide the airflow blown onto the first surface 213 / second surface 223 to smoothly turn and eventually flow to the lower air outlet 13, thus helping to reduce airflow loss.

[0097] In some exemplary embodiments, the first surface 213 is concave and the second surface 223 is convex, and the first surface 213 is constructed as a fastest curve surface that fits the fastest curve.

[0098] The first curved surface 213 is concave, which enhances the adhesion effect of the airflow, facilitating the smooth redirection of the airflow onto the first curved surface 213 and directing it towards the second curved surface 223, thus reducing airflow loss. Furthermore, since the first curved surface 213 is the brachistochrone surface, it accelerates the airflow speed and increases the outlet velocity. The second curved surface 223 is convex, which easily breaks the adhesion effect of the wind, reducing the phenomenon of the wind continuing along the second curved surface 223, and preventing the airflow on the second curved surface 223 from concentrating at the end for redirection. This accelerates airflow redirection and improves the uniformity of the lower outlet 13. Therefore, this design effectively improves both outlet efficiency and outlet uniformity.

[0099] In some exemplary embodiments, based on the air outlet module being in the third air outlet mode and the second air guide plate 22 being in the fifth position, the end of the second air guide plate 22 away from the second rotating connection portion contacts the first air guide plate 21, such as... Figure 6 As shown. This can prevent airflow from flowing between the first air guide plate 21 and the second air guide plate 22, which would create vortices and affect the air volume.

[0100] In some exemplary embodiments, the third position is located between the first position and the second position (excluding the first and second positions), such as... Figure 6 As shown, this ensures that when the air outlet module is in the third air outlet mode, the first sub-air outlet 11 and the lower air outlet 13 can both emit air, thus achieving dual air outlets. At this time, the second air guide plate 22 can be located in any position (including the fourth and fifth positions), as long as it does not conflict with the position of the first air guide plate 21.

[0101] Alternatively, the first air guide plate 21 can also be located in the second position. In this case, the second air guide plate 22 can be located in any position other than the fourth position, so that the second sub-air outlet 12 and the lower air outlet 13 can be connected to the air outlet, thus achieving dual air outlet.

[0102] In some embodiments, based on the first air guide plate 21 being located at a first position, the included angle α between the first air guide plate 21 and the plane where the first sub-air outlet 11 is located (e.g., Figure 5 (As shown) The airflow can be within the range of 0° to 150°, such as 0°, 30°, 45°, 60°, 90°, 120°, 150°, etc. Tests have verified that this airflow effect is good.

[0103] 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 plane where the first air guide plate 21 and the first sub-air outlet 11 are located can be defined as the angle between the rotation axis of the first air guide plate 21 and the plane where the end of the first air guide plate 21 away from the first rotating connection part is located and the vertical plane (or 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 13 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 13 near the rotation axis of the first air guide plate 21 and the vertical plane).

[0104] Based on the fact that the second air guide plate 22 is located in the fifth position, the included angle β between the plane where the second air guide plate 22 and the second sub-air outlet 12 are located (e.g.) Figure 6 (As shown) The airflow can be within the range of 30° to 180°, such as 30°, 45°, 60°, 90°, 120°, 150°, 180°, etc. Tests have verified that this airflow effect is good.

[0105] The cross-section of the air guiding portion of the second air guide plate 22 can be, but is not limited to, an arc shape. The angle between the plane where the second air guide plate 22 and the second sub-air outlet 12 are located can be defined as the angle between the rotation axis of the second air guide plate 22 and the plane where the end of the second air guide plate 22 away from the second rotating connection part is located and the vertical plane (or defined as the angle between the tangent of the middle part of the surface of the second air guide plate 22 away from the lower air outlet 13 and the vertical plane, or defined as the angle between the tangent of the end of the surface of the second air guide plate 22 away from the lower air outlet 13 near the rotation axis of the second air guide plate 22 and the vertical plane).

[0106] In some exemplary embodiments, the width of the first sub-vent 11 is equal to the width of the lower air outlet 13, so that the opening and closing of the first sub-vent 11 and the lower air outlet 13 can be controlled by the first air guide plate 21.

[0107] like Figures 4 to 6 As shown, the width of the second sub-air outlet 12 is less than or equal to the width of the first sub-air outlet 11. In this way, the widths of the first sub-air outlet 11 and the lower air outlet 13 are not too small, ensuring that both the lower and side air outlets have good air delivery performance.

[0108] In some exemplary embodiments, 0.1 ≤ L2 / L1 ≤ 0.5, such as 0.1, 0.2, 0.3, 0.4, 0.5, etc. If L2 is too small, the lower air outlet 13 will be too small, causing the air velocity in the air outlet cavity 18 to increase sharply when entering the lower air outlet 13, resulting in a high noise level and easy condensation problems. If L1 is too small, the space of the air inlet heat exchange cavity will be too small, resulting in the fan 3 being too small, and the air volume cannot meet the performance requirements (for example, the body size reaches the size of a 1.5 horsepower unit, but the performance of a 1.5 horsepower unit cannot be achieved). After research and testing, limiting L2 / L1 to the above range can take into account both the noise and condensation problems when the air is vented downwards, and can also meet the air volume requirements of the unit. Of course, L2 / L1 is not limited to the above range and can be adjusted as needed.

[0109] In some exemplary embodiments, 40mm ≤ L2 ≤ 120mm, such as 40mm, 60mm, 80mm, 100mm, 120mm, etc. This can accommodate the installation requirements of the first and second air guiding mechanisms of the air outlet module, as well as the overall size requirements of the air outlet housing 102. Of course, L2 is not limited to the above range and can be adjusted as needed.

[0110] In some exemplary embodiments, the second air guide plate 22 is located below the first air guide plate 21, and the width of the second air guide plate 22 is less than or equal to the width of the first air guide plate 21. In this way, the width of the second air guide plate 22 is not too large, so as not to cause the height of the housing 1 to be too high, and it is not easy to interfere with the structure inside the housing 1.

[0111] In some exemplary embodiments, such as Figure 2 As shown, the lower air outlet 13 has an overlapping edge 141 at the end away from the side air outlet. The overlapping edge 141 is configured to overlap with the first air guide plate 21 when the first air guide plate 21 is rotated to the first position. This can improve the closing effect of the first air guide plate 21 on the lower air outlet 13, reduce the air leakage in the side air outlet mode, and help prevent condensation and whistling.

[0112] like Figure 2 As shown, the overlapping edge 141 is lower than the first rotating connection. Therefore, when the first air guide plate 21 closes the lower air outlet 13, it is in an inclined state, not a horizontal state, so the lower air outlet 13 is an inclined opening. With a consistent width in the horizontal direction, the inclined lower air outlet 13 has a larger area than the horizontally positioned lower air outlet 13, which helps to increase the airflow of the lower air outlet 13.

[0113] The boundary between the air inlet heat exchange chamber 17 and the air outlet chamber can be defined by the location of the overlapping edge 141.

[0114] In some exemplary embodiments, the air inlet heat exchange chamber 17 includes an air inlet chamber and a heat exchange chamber, with the heat exchange chamber located between the air inlet chamber and the air outlet chamber. The fan 3 is disposed within the air inlet chamber, and the heat exchanger 4 is disposed within the heat exchange chamber. A water collection tray 19 is provided at the bottom of the heat exchange chamber, with one end of the water collection tray 19 near the lower air outlet 13 connected to the overlapping edge 141. Figure 2 As shown, the air inlet chamber and the heat exchange chamber can be divided by the middle partition 171.

[0115] The overlapping edge 141 and the water tray 19 can, but are not limited to, form an integrated structure, and the lower air outlet 13 and the water tray 19 can, but are not limited to, form an integrated structure. This facilitates installation and reduces wind resistance.

[0116] In some exemplary embodiments, such as Figure 1 , Figure 5 and Figure 6 As shown, the air outlet housing 102 is provided with a first overlapping edge 14 (including the overlapping edge 141 connected to the water receiving tray in the aforementioned embodiment) and a second overlapping edge 15. Based on the first air guide plate 21 rotating to the first position, the first air guide plate 21 overlaps with the first overlapping edge 14, as shown... Figure 2 and Figure 5 As shown. Based on the first air guide plate 21 rotating to the second position, the first air guide plate 21 overlaps with the second overlapping edge 15, as... Figure 1 and Figure 4 As shown.

[0117] This helps to improve the closing effect of the first air guide plate 21 on the first sub-air outlet 11 and the lower air outlet 13, thereby helping to prevent condensation and air leakage.

[0118] For the design where the air outlet housing 102 does not have a second sub-air outlet 12, the first overlapping edge 14 is arranged in a ring shape along the circumference of the lower air outlet 13, and the second overlapping edge 15 is arranged in a ring shape along the circumference of the first sub-air outlet 11. This facilitates the circumferential sealing of the first air guide plate 21 to the first sub-air outlet 11 and the lower air outlet 13.

[0119] For the design where the air outlet housing 102 has a second sub-air outlet 12, the first overlapping edge 14 is arranged along the circumference of the lower air outlet 13 to form a semi-enclosed structure, and the second overlapping edge 15 is arranged along the circumference of the first sub-air outlet 11 to form a semi-enclosed structure. This helps to improve the closing effect of the first air guide plate 21 on the first sub-air outlet 11 and the lower air outlet 13. Similarly, the air outlet housing 102 can also be provided with a third overlapping edge 16, such as... Figure 5 As shown, the third overlapping edge 16 is arranged around the second sub-air vent 12 to form a semi-enclosed structure. Based on the second air guide plate 22 rotating to the fourth position, the second air guide plate 22 overlaps with the third overlapping edge 16. This helps to improve the closing effect of the second air guide plate 22 on the second sub-air vent 12, thereby helping to prevent condensation and air leakage.

[0120] In some exemplary embodiments, such as Figures 4 to 6 As shown, the air outlet housing 102 is provided with a first sub-air outlet 11, a second sub-air outlet 12, and a lower air outlet 13. The first rotating shaft 211 of the first air guide plate 21 and the second rotating shaft 221 of the second air guide plate 22 are coaxially nested and independently rotated. This air outlet module can operate according to the following logic: When cooling is in operation, the air vent module automatically identifies parameters and defaults to rapid cooling mode. For example... Figure 4 As shown, at this time, the first sub-vent 11 and the second sub-vent 12 of the air outlet module are closed, the lower air outlet 13 is open, and the air outlet mode is activated. Cold air quickly falls to the ground. At this time, the first air guide plate 21 is in the second position and the second air guide plate 22 is in the fourth position. After running continuously for t1 minutes, the lower air outlet 13 of the air outlet module closes, the first sub-vent 11 opens, the first air guide plate 21 is in the first position, and the second air guide plate 22 remains in the fourth position. The system continues to operate in the side air outlet mode (e.g., ...). Figure 5 (As shown), to prevent the cold air from continuing to blow on people.

[0121] When cooling is in operation, the air vent module automatically identifies parameters. If it detects that the user has selected the normal cooling mode, it will operate in side-discharge mode. Figure 5 As shown, at this time, the first air guide plate 21 is in the first position and the second air guide plate 22 is in the fourth position.

[0122] When cooling is in operation, the air vent module automatically identifies parameters and recognizes that the user has selected the full-area cooling mode, operating in dual-outlet mode. Figure 6As shown, at this time, the first air guide plate 21 is in the third position and the second air guide plate 22 is in the fifth position, realizing whole-house air supply.

[0123] When in heating mode, the air vent module automatically identifies parameters and defaults to rapid heating mode. At this time, the first sub-air vent 11 and the second sub-air vent 12 of the air vent module are closed, and the lower air outlet 13 is open. Press the air outlet status button to operate (e.g., ...). Figure 4 As shown), at this time, the first air guide plate 21 is in the second position and the second air guide plate 22 is in the fourth position. After running continuously for t2 minutes, the lower air outlet 13 of the air outlet module remains open, the first sub-air outlet 11 and the second sub-air outlet 12 are open, the first air guide plate 21 is in the third position and the second air guide plate 22 is in the fifth position, and it continues to operate in dual air outlet mode (as shown). Figure 6 (As shown).

[0124] When heating is in operation, the air vent module automatically identifies parameters and recognizes that the user has selected the normal heating mode, operating in side-discharge mode (e.g., ...). Figure 5 As shown in the figure, at this time, the first air guide plate 21 is in the first position and the second air guide plate 22 is in the fourth position.

[0125] When heating is in operation, the air vent module automatically identifies parameters and recognizes that the user has selected the full-area heating mode, operating in dual-airflow mode. At this time, the first air guide plate 21 is in the third position and the second air guide plate 22 is in the fifth position.
