Detailed Implementation

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] Air conditioners regulate indoor temperature, improving indoor comfort. The direction of airflow directly affects the air conditioner's cooling and heating performance, as well as the user's experience. To increase the airflow direction of the indoor unit, air deflectors are typically installed. However, because the deflector's movement is limited, and the airflow direction differs when blowing out cold and hot air, the airflow is confined to a specific area of ​​the room, reducing cooling and heating efficiency and impacting the user experience.

[0026] This disclosure proposes an air guide plate movement mechanism, which is disposed at the air outlet of an air conditioner and is used to connect with the air guide plate and drive the air guide plate to move to block or open the air outlet. Figure 1 This is a three-dimensional structural schematic diagram of a wind deflector motion mechanism according to an exemplary embodiment of this disclosure; Figure 2 This is a partial three-dimensional structural diagram of an indoor unit of an air conditioner according to an exemplary embodiment of this disclosure. For example... Figure 1 , Figure 2 As shown, Figure 1 The double-dotted arrow represents the direction of the first rotational force F1, the dashed arrow represents the direction of the second rotational force F2, and the dotted-dotted arrow represents the translational force F3. The air guide plate movement mechanism 1 includes a first drive assembly 11 and a second drive assembly 12, located at the air outlet 241 of the indoor unit 2 of the air conditioner. These components connect to the air guide plate 21 and drive the air guide plate 21 to move, thus blocking or opening the air outlet 241. The air guide plate movement mechanism 1 includes a first drive assembly 11 and a second drive assembly 12. The first drive assembly 11 includes a first power output shaft 114 fixedly connected to the air guide plate 21. The first power output shaft 114 can output the first rotational force F1 to the air guide plate 21 to drive the air guide plate 21 to rotate. The second drive assembly 12 includes a second power output shaft 123 and a power conversion component 121. The second power output shaft 123 is connected to the power conversion component 121 to output a second rotational force F2 to the power conversion component 121. The power conversion component 121 is fixedly connected to the first drive assembly 11. The power conversion component 121 is used to convert the second rotational force F2 into a translational force F3 that moves in a straight line. Under the action of the translational force F3, the first drive assembly 11 moves in a straight line and drives the air guide plate 21 to move synchronously.

[0027] Since the air guide plate movement mechanism 1 includes a first drive assembly 11 and a second drive assembly 12, the first power output shaft 114 of the first drive assembly 11 is fixedly connected to the air guide plate 21 to drive the air guide plate 21 to rotate, and the second power output shaft 123 of the second drive assembly 12 is connected to the power conversion component 121 to output a second rotational force F2 to the power conversion component 121. The power conversion component 121 and the first drive assembly 11 are fixedly connected to drive the first drive assembly 11 and the air guide plate 21 to move. The first drive assembly 11 and the second drive assembly 12 enable the air guide plate 21 to move and rotate. The simple structure improves the structural reliability of the air guide plate movement mechanism 1, and also enriches the spatial posture of the air guide plate 21 relative to the air outlet 241, thereby increasing the air outlet range of the air conditioner and improving the cooling and heating effect and user experience of the indoor unit 2 of the air conditioner.

[0028] It should be noted that the first driving component 11 and the second driving component 12 can operate individually or simultaneously to drive the air guide plate 21 to move. In some embodiments, the first driving component 11 can first drive the air guide plate 21 to rotate, and then the second driving component 12 can drive the first driving component 11 and the air guide plate 21 to move. In other embodiments, the second driving component 12 can first drive the first driving component 11 and the air guide plate 21 to move, and then the first driving component 11 can drive the air guide plate 21 to rotate. In still other embodiments, the first driving component 11 and the second driving component 12 can simultaneously drive the air guide plate 21 to achieve spatial movement. In other embodiments, the first driving component 11 and the second driving component 12 can be alternately controlled to drive the air guide plate 21 to move. This disclosure does not limit the driving sequence, combined driving method, or movement trajectory of the air guide plate 21.

[0029] Figure 1 The double-dotted arrow represents the direction of the first rotational force F1. The first power output shaft 114 of the first drive assembly 11 is fixedly connected to the air guide plate 21 to output the first rotational force F1 to the air guide plate 21 and drive the air guide plate 21 to rotate. The rotation of the air guide plate 21 can be between an initial angle α and a working angle β deflected relative to the initial angle α. The initial angle α can be the angle between the air guide plate 21 and the vertical direction when it blocks the air outlet 241, and the working angle β can be any angle between the air guide plate 21 and the vertical direction after it deflects relative to the initial angle α.

[0030] In some embodiments, the first power output shaft 114 can rotate clockwise and counterclockwise to drive the air guide plate 21 to rotate in two different directions. When the first rotational force F1 output by the first power output shaft 114 is clockwise, the first rotational force F1 can drive the air guide plate 21 to rotate from a first position to a second position. When the first rotational force F1 output by the first power output shaft 114 is counterclockwise, the first rotational force F1 can drive the air guide plate 21 to rotate back from the second position to the first position. For example, when the air guide plate 21 is in the first position, the air guide plate 21 forms an initial angle α with the vertical direction. When the air guide plate 21 is in the second position, the air guide plate 21 forms a working angle β with the vertical direction. The first power output shaft 114 can drive the air guide plate 21 to rotate from the first position at the initial angle α to the second position at the working angle β by rotating clockwise, and the first power output shaft 114 can drive the air guide plate 21 to rotate from the second position at the working angle β to the first position at the initial angle α by rotating counterclockwise.

[0031] In some embodiments, such as Figure 3 As shown, the first drive assembly 11 includes a transmission connector and a first motor 111. The first power output shaft 114 can be the rotating shaft of the first motor 111. The transmission connector is fixedly connected to the first power output shaft 114, and the air guide plate 21 is fixedly connected to the transmission connector, so that the air guide plate 21 rotates between the initial angle α and the working angle β under the action of the first rotational force F1. Driving the transmission connector with the first motor 111 and driving the air guide plate 21 fixedly connected to the transmission connector simplifies the structural setup and improves the reliability of the structural setup that makes the air guide plate 21 rotate. The first motor 111 can be a stepper motor to facilitate driving the transmission connector to rotate.

[0032] In the above embodiment, the transmission connector includes a hook structure 112 connected to the first power output shaft 114 of the first motor 111, and the hook structure 112 is snapped and fixed to the air guide plate 21. The hook structure 112 is fixedly connected to the first power output shaft 114. The hook structure 112 can be set outside the first motor 111 and is snapped and fixed to the air guide plate 21 as a whole with the first motor 111. During the assembly process, it is only necessary to snap and fix the first motor 111 and the hook structure 112 as a whole to the air guide plate 21. The overall structure of the first drive assembly 11 is simple, which improves the assembly convenience and reliability of the first drive assembly 11 and the air guide plate 21.

[0033] The latch structure 112 may include a pair of latching bodies 1121 arranged opposite each other. One end of each latching body 1121 is connected to the first motor 111, and the other end of each latching body 1121 is provided with a latch 1122, which is latched and fixed to the air guide plate 21. The ends of the pair of latching bodies 1121 connected to the first motor 111 can be integrated into one unit. For example, the shaft of the first motor 111 can be fixed to the bottom connection structure of the pair of latching bodies 1121 to facilitate fixation with the shaft of the first motor 111. The two latches 1122 located at the other end of the pair of latching bodies 1121 are arranged back to back to facilitate fixation to the air guide plate 21 via the two latches 1122, improving assembly convenience and stability.

[0034] like Figures 2-5 As shown, the air guide plate 21 may be provided with assembly holes 215, assembly grooves 1311, etc., for engaging and fixing with the hook structure 112. Taking the air guide plate 21 with assembly holes 215 as an example, the edge of the assembly hole 215 may be provided with a recess 2151 for limiting, the engaging body 1121 is provided with a retaining rib, and the hook 1122 passes through the assembly hole 215 and engages and fixes with the edge of the assembly hole 215. The retaining rib and the recess 2151 limit the engagement to prevent the engaging body 1121 from rotating within the assembly hole 215. Or, as Figure 6 As shown, the assembly hole 215 can also be set as a cross-shaped hole. When the hook structure 112 is assembled into the assembly hole 215, the structure of the cross-shaped assembly hole 215 can limit the bottom of the hook structure 112 and prevent the hook structure 112 from rotating. In one embodiment, the air guide plate 21 may include an air damper body 211 and mounting plates 212 disposed at both ends of the air damper body 211. The mounting plates 212 are perpendicular to the air damper body 211 or at other angles. The assembly groove 1311, the assembly hole 215 and other structures for engaging and fixing with the hook structure 112 can be disposed on the mounting plate 212 to facilitate the connection between the first drive assembly 11 and the air guide plate 21.

[0035] In some embodiments, the first motor 111 includes a first end 1111 and a second end 1112 disposed opposite to each other. A transmission connector is disposed on the end face of the first end 1111, and a second drive assembly 12 is fixedly connected to the second end 1112 and extends from the side of the second end 1112. Since the transmission connector and the second drive assembly 12 are located at both ends of the first motor 111, structural interference between the transmission connector and the second drive assembly 12 is avoided.

[0036] The second drive assembly 12 includes a second power output shaft 123 and a power conversion component 121. The second power output shaft 123 is connected to the power conversion component 121 to output a second rotational force F2 to the power conversion component 121. The power conversion component 121 is fixedly connected to the first drive assembly 11. The power conversion component 121 is used to convert the second rotational force F2 into a translational force F3 that moves in a straight line. Under the action of the translational force F3, the first drive assembly 11 moves in a straight line and drives the air guide plate 21 to move synchronously. The movement of the air guide plate 21 can be a translational movement from the initial position to the working position. The initial position of the air guide plate 21 can be the position when it blocks the air outlet 241, or the position when the air guide plate 21 is at any working angle β. The working position of the air guide plate 21 can be any position after translation relative to the initial position.

[0037] The second power output shaft 123 can rotate clockwise and counterclockwise to drive some components in the power conversion unit 121 to perform telescopic movements. When the second rotational force F2 output by the second power output shaft 123 is clockwise, the second rotational force F2 can drive the first motor 111 to move from the third position to the fourth position in a straight line, and the air guide plate 21, which is fixedly connected to the first power output shaft 114 of the first motor 111, moves from the fifth position to the sixth position in a straight line. When the second rotational force F2 output by the second power output shaft 123 is counterclockwise, the second rotational force F2 can drive the first motor 111 to move from the fourth position to the third position in a straight line, and the air guide plate 21, which is fixedly connected to the first power output shaft 114 of the first motor 111, moves from the sixth position to the fifth position in a straight line. For example, the fifth position can be the initial position mentioned above, and the sixth position can be a working position that deviates from the initial position. The second power output shaft 123 can drive the air guide plate 21 to move from the initial position to the working position by rotating in the forward direction, and the second power output shaft 123 can drive the air guide plate 21 to move from the working position to the initial position by rotating in the reverse direction.

[0038] In some embodiments, such as Figures 7-9 The second drive assembly 12 shown also includes a second motor 122, and the second power output shaft 123 can be the rotating shaft of the second motor 122. The power conversion component 121 includes a first threaded part 1212 and a second threaded part 1213. Figure 7 The dashed arrow in the diagram represents the direction of movement of the second threaded component 1213. The second power output shaft 123 is connected to the first threaded component 1212 so that the second rotational force F2 drives the first threaded component 1212 to rotate. The second threaded component 1213 is threadedly connected to the first threaded component 1212, and the second threaded component 1213 moves along the thread extension direction under the drive of the first threaded component 1212.

[0039] In one embodiment, the first threaded component 1212 can be a threaded rod, and the second threaded component 1213 can be a threaded sleeve. The second power output shaft 123 of the second motor 122 is connected to the threaded rod so that the second rotational force F2 drives the threaded rod to rotate. The threaded sleeve is disposed on the outer surface of the threaded rod and is threadedly connected to the threaded rod. When the threaded sleeve is subjected to the rotational force output by the threaded rod, it moves along the axial extension direction of the threaded rod. The threaded connection between the threaded rod and the threaded sleeve enables the power conversion component 121 to convert the rotation of the second power output shaft 123 into axial movement, resulting in a simple structure and high reliability.

[0040] Alternatively, in another embodiment, the first threaded component 1212 can be a threaded sleeve, and the second threaded component 1213 can be a threaded rod. The second power output shaft 123 of the second motor 122 is connected to the threaded sleeve so that the second rotational force F2 drives the threaded sleeve to rotate. The threaded rod is disposed inside the threaded sleeve and threadedly connected to the threaded sleeve. When the threaded rod is subjected to the rotational force output by the threaded sleeve, it moves along the axial extension direction of the threaded sleeve. The threaded connection between the threaded rod and the threaded sleeve enables the power conversion component 121 to convert the rotation of the second power output shaft 123 into axial movement, resulting in a simple structure and high reliability.

[0041] In some embodiments, one end of the second threaded member 1213 may be fixed to the first drive assembly 11 to drive the first drive assembly 11 and the second threaded member 1213 to move synchronously. In other embodiments, the power conversion component 121 further includes a fixed connector 1214, one end of which is fixedly connected to the second threaded member 1213, and the other end of which is fixedly connected to the first drive assembly 11.

[0042] In the above embodiment, the first motor 111 includes a first end 1111 and a second end 1112 disposed opposite to each other. A transmission connector is disposed on the end face of the first end 1111, and a second drive assembly 12 is fixedly connected to the second end 1112 and extends from the side of the second end 1112. Since the transmission connector and the second drive assembly 12 are located at both ends of the first motor 111, structural interference between the transmission connector and the second drive assembly 12 is avoided. Specifically, the second threaded member 1213 or the fixed connector 1214 in the power conversion component 121 can be fixedly connected to the second end 1112.

[0043] In some embodiments, such as Figure 10As shown, the power conversion component 121 may further include a limiting sleeve 1215, and the second threaded member 1213 is at least partially disposed within the limiting sleeve 1215 and moves within the limiting sleeve 1215. One of the inner walls of the limiting sleeve 1215 and the second threaded member 1213 is provided with a limiting rib 1215a, and the other is provided with a limiting groove 1213a. The limiting rib 1215a and the limiting groove 1213a cooperate to prevent the second threaded member 1213 from rotating circumferentially.

[0044] In some embodiments, the power conversion component 121 further includes a protective sleeve 1216, and a second threaded member 1213 is disposed within the protective sleeve 1216. The portion of the second drive assembly 12 that is fixedly connected to the first motor 111 may be disposed at one end of the protective sleeve 1216. For example, one end of the protective sleeve 1216 may be provided with an assembly plate 1211, or the aforementioned fixed connector 1214 may be assembled at one end of the protective sleeve 1216 to facilitate the fixed connection between the second drive assembly 12 and the first motor 111.

[0045] In some embodiments, such as Figure 11 As shown, the air guide plate movement mechanism 1 also includes a motor base 13. The motor base 13 includes a main body 131 and a mounting part 132 disposed on the main body 131. The second drive assembly 12 is fixedly assembled to the main body 131. The motor base 13 is fixedly mounted to the indoor unit 2 of the air conditioner via the mounting part 132, while the second drive assembly 12 is fixedly assembled to the main body 131. Therefore, the second drive assembly 12 is installed and fixed through the motor base 13.

[0046] The indoor unit 2 of the air conditioner may include a base 23 and an air guide plate assembly structure 22 located above the base 23. A mounting part 132 can be fixedly connected to the base 23. A first drive assembly 11 can be located above the air guide plate assembly structure 22, and a second drive assembly 12 can be located below the air guide plate assembly structure 22. The air guide plate assembly structure 22 may have a clearance hole 221, through which a power conversion component 121 can be fixedly connected to a first motor 111. Specifically, the top of the power conversion component 121 may have an assembly plate 1211 with a hole structure. The first motor 111 may have an assembly groove 113, into which the assembly plate 1211 can extend and be fixedly connected to the first motor 111 via threaded connectors, connecting pins, snap-fit ​​components, or other structures. The assembly plate 1211 structure occupies little space, facilitating assembly and fixation with the first motor 111.

[0047] In the above embodiment, the main body 131 is provided with an assembly groove 1311, at least a portion of the second drive assembly 12 is received in the assembly groove 1311, and the second drive assembly 12 is fixedly connected to the assembly groove 1311. The mounting part 132 includes at least one lug structure extending from the assembly groove 1311, and the lug structure is provided with a mounting hole. For example, the second motor 122 of the second drive assembly 12 can be fixedly received in the assembly groove 1311, and lug structures are provided on both sides of the main body 131. The motor base 13 can be fixed to the indoor unit 2 of the air conditioner through the mounting hole by a connecting structure such as a threaded connector, so as to improve the assembly stability of the motor base 13.

[0048] It should be noted that the first motor 111 may include a first end 1111 and a second end 1112 arranged opposite to each other. The transmission connector is disposed on the end face of the first end 1111. The power conversion component 121 is fixedly connected to the second end 1112 and extends from the side of the second end 1112, so that most of the structure of the first motor 111 and the second motor 122 are located on the same side of the power conversion component 121, which optimizes the layout of the air guide plate movement mechanism 1 and reduces space occupation.

[0049] In some embodiments, such as Figure 12 As shown, the air guide plate 21 includes a third end 213 and a fourth end 214 disposed laterally opposite to each other. An air guide plate movement mechanism 1 is disposed at at least one of the third end 213 and the fourth end 214. Distributing the air guide plate movement mechanism 1 at the third end 213 and / or the fourth end 214 reduces structural interference of the air guide plate movement mechanism 1 with the air guide plate 21 and reduces the space occupied by the air guide plate 21 on the indoor unit 2 of the air conditioner. In one embodiment, the third end 213 and the fourth end 214 may each be provided with an air guide plate movement mechanism 1, so that the air guide plate 21 can be moved by the air guide plate movement mechanism 1 located at both ends of the air guide plate 21, thereby improving the movement stability of the air guide plate 21. Alternatively, the air guide plate movement mechanism 1 may also be disposed at other positions on the air guide plate 21; this disclosure does not limit this.

[0050] This disclosure further proposes an indoor unit 2 for an air conditioner, such as Figure 12 , Figure 13 As shown, the indoor unit 2 of the air conditioner includes: a housing 24, an air guide plate 21, and the aforementioned air guide plate movement mechanism 1. An air outlet 241 is provided on the housing 24, and the air guide plate 21 can move under the action of the air guide plate movement mechanism 1 to block or open the air outlet 241.

[0051] Since the air guide plate movement mechanism 1 includes a first drive assembly 11 and a second drive assembly 12, the first power output shaft 114 of the first drive assembly 11 is fixedly connected to the air guide plate 21 to drive the air guide plate 21 to rotate, and the second power output shaft 123 of the second drive assembly 12 is connected to the power conversion component 121 to output a second rotational force F2 to the power conversion component 121. The power conversion component 121 and the first drive assembly 11 are fixedly connected to drive the first drive assembly 11 and the air guide plate 21 to move. The first drive assembly 11 and the second drive assembly 12 enable the air guide plate 21 to move and rotate. The simple structure improves the structural reliability of the air guide plate movement mechanism 1, and also enriches the spatial posture of the air guide plate 21 relative to the air outlet 241, thereby increasing the air outlet range of the air conditioner and improving the cooling and heating effect and user experience of the indoor unit 2 of the air conditioner.

[0052] The first drive assembly 11 and the second drive assembly 12 can operate individually or simultaneously to drive the air guide plate 21. This disclosure does not limit the operating order of the first drive assembly 11 and the second drive assembly 12. The position of the air guide plate 21 can be associated with the operating mode of the air conditioner, for example... Figure 14 As shown, when the air conditioner is in cooling mode, taking the second drive component 12 working first and the first drive component 11 working later as an example, the second drive component 12 can drive the first drive component 11 and the air guide plate 21, causing the air guide plate 21 to move from its initial position blocking the air outlet 241 to a position deviating from its working position. Then, the first drive component 11 drives the air guide plate 21 to rotate to its bottom limit working position, so that the cold air blows upward, resulting in good cooling effect and providing the user with a shower-like airflow experience. For example... Figure 15 As shown, when the air conditioner is in heating mode, taking the second drive component 12 working first and the first drive component 11 working later as an example, the second drive component 12 can drive the first drive component 11 and the air guide plate 21, causing the air guide plate 21 to move from its initial position blocking the air outlet 241 to a position deviating from its working position. Then, the first drive component 11 drives the air guide plate 21 to rotate to its top extreme working position, so that hot air is blown downwards, resulting in good heating effect and providing users with a carpet-like airflow experience. For example, the air guide plate 21 can also be driven to other positions by the first drive component 11 and the second drive component 12 in cooperation to achieve other airflow effects such as windless airflow.

[0053] In other embodiments, the first drive component 11 and the second drive component 12 can also work separately or simultaneously to make the air guide plate 21 cooperate with the air outlet 241 to obtain a dynamic air outlet effect. Since the air guide plate 21 can both move and rotate, it has a variety of dynamic positions, which increases the sweeping range of the air conditioner and improves the cooling and heating effect of the air conditioner.

[0054] It should be noted that the aforementioned indoor unit 2 of the air conditioner can be an indoor unit of a fresh air air conditioner, or it can be an indoor unit of an air conditioner that does not include a fresh air function. This disclosure does not impose any restrictions on this.

[0055] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the technical solutions disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and embodiments are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0056] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
