[0002] Air guide vanes are important components of ventilation equipment, guiding the airflow from the outlet and opening and closing the outlet. In existing technologies, some ventilation systems use a single air guide vane at the outlet, resulting in a narrow range of adjustment for airflow direction and volume, poor air guiding effect, and a single airflow mode, failing to meet diverse user needs and leading to a poor user experience.

[0022] Determining the target positions of the multiple air guide plates based on the target state of the air outlet includes:

[0023] When the air outlet is in its initial state, the first air guide plate is located outside the air outlet, and the surface of the first air guide plate is parallel to the preset reference line. The second air guide plate is close to the lower edge of the air outlet, and the third air guide plate is close to the upper edge of the air outlet. The preset reference line is set obliquely downward from the inside of the air outlet to the outside of the air outlet.

[0024] When the air outlet is in the upward air outlet state, the first air guide plate is close to the upper edge of the air outlet, the second air guide plate is located outside the air outlet, and the third air guide plate is close to the lower edge of the air outlet.

[0025] When the air outlet is in the downward air outlet state, the first air guide plate is close to the lower edge of the air outlet, the second air guide plate is close to the upper edge of the air outlet, and the third air guide plate is located on the outside of the air outlet.

[0026] When the air outlet is in a state of simultaneous airflow from the top and bottom, the second air guide plate is away from the upper or lower edge of the air outlet, and the third air guide plate is away from the lower or upper edge of the air outlet.

[0029] When the target state of the air outlet is the upward air outlet state, the target rotation angle of the rotating shaft is θ = α;

[0031] When the target state of the air outlet is simultaneous airflow from the top and bottom, the target rotation angle of the rotating shaft is θ < α, α < θ < α + β, and α + β < θ < 360°.

[0032] Further optionally, the air outlet can also be in a closed state; when the air outlet is in a closed state, the first air guide plate is located inside the air outlet, the second air guide plate is close to the upper edge of the air outlet, and the third air guide plate is close to the lower edge of the air outlet.

[0033] When the current state of the air outlet is the initial state and the target state of the air outlet is the closed state, the target rotation angle of the rotating shaft is θ = α + 0.5 * β.

[0034] Compared with the prior art, the main advantages of the present invention are as follows:

[0035] (1) Multiple air guide plates can rotate synchronously with the rotating shaft. When the rotating shaft is rotated to different angles, the air outlet can be closed, air can be discharged from the top and bottom at the same time, air can be discharged from the top alone, and air can be discharged from the bottom alone. The air volume of the air outlet can be adjusted by adjusting the rotation angle of the rotating shaft. The air outlet has a large range of adjustment for air direction, air volume and air delivery distance. The air guiding effect is obvious and the air outlet mode is diverse, which can meet the different needs of users. The structure and control method are simple, occupy little space, have little vibration and stable movement. It solves the problems of narrow air direction adjustment range and single air outlet mode of a single air guide plate, and solves the problems of complex structure, complicated control process and unstable movement of multiple air guide plates.

[0036] (2) Both sides of each air guide plate in the thickness direction are wing-shaped structures. The connection between the air guide plate and the rotating shaft is smooth, which reduces the resistance when the air passes through, optimizes the air flow path, reduces the loss of air volume, and can achieve large-scale and long-distance air supply. The air supply is uniform and the air volume is sufficient, which improves the comfort of air supply. Both sides of each air guide plate in the thickness direction have a raised structure, which plays a role in turbulence.

[0037] (3) The length of one of the three air guide plates is smaller than that of the other two; compared with the combination of three air guide plates of the same size, the combination of different sizes can achieve more air outlet effect; determine the target rotation angle of the rotating shaft according to the current position and target position of the air guide plate, and control the target rotation angle of the rotating shaft to make the air outlet in the target state.

[0050] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0052] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0053] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0054] In existing technologies, some ventilation equipment has a single air guide plate at the air outlet, which results in a narrow range of adjustment for the air outlet's direction and volume, poor air guiding effect, and a single air outlet mode, making it difficult to meet different user needs and leading to a poor user experience. Other ventilation equipment has multiple air guide plates at the air outlet, but each air guide plate needs to be controlled independently, making the air guide plate device complex in structure, cumbersome in control process, large in space occupation, and unstable in movement.

[0055] This invention creatively provides an air guide plate device for ventilation equipment. The ventilation equipment has an air outlet. The air guide plate device includes a rotating shaft and air guide plates. The rotating shaft is rotatably disposed at the air outlet. Multiple air guide plates are arranged alternately on the rotating shaft along its circumference. When the rotating shaft rotates, the multiple air guide plates can rotate synchronously. By controlling the rotating shaft to different angles, the air outlet can be closed, simultaneously discharged from the top and bottom, discharged from the top alone, or discharged from the bottom alone. By adjusting the rotation angle of the rotating shaft, the air volume of the air outlet can be adjusted. The structure and control method are simple, occupy little space, and have stable operation.

[0056] <Air guide plate device>

[0057] like Figure 1a and Figure 1bAs shown, this embodiment provides an air guide plate device for ventilation equipment, especially for wall-mounted air conditioners; the ventilation equipment has an air outlet 311, the air guide plate device is disposed at the air outlet 311 and includes a rotating shaft 2 and air guide plates, the rotating shaft 2 is rotatably disposed at the air outlet 311, and the axis of the rotating shaft 2 is consistent with the length direction of the air outlet 311; multiple air guide plates are included, and the multiple air guide plates are arranged alternately on the rotating shaft 2 along the circumference of the rotating shaft 2; when the rotating shaft 2 rotates, the multiple air guide plates can rotate synchronously; the number of air guide plates is not limited, but the number of air guide plates is greater than 2. In this embodiment, the air guide plates include a first air guide plate 11, a second air guide plate 12 and a third air guide plate 13;

[0058] Furthermore, the length direction of each air guide plate is consistent with the axial direction of the rotating shaft 2; the surface of each air guide plate passes through the axis of the rotating shaft 2; the width of each air guide plate can be different, or among the three air guide plates, at least one air guide plate has a width smaller than the width of the other air guide plates; in this embodiment, the width of the first air guide plate 11 is smaller than the width of the second air guide plate 12, and the width of the second air guide plate 12 is equal to the width of the third air guide plate 13.

[0059] In summary, multiple air guide vanes can rotate synchronously with the rotating shaft 2. By controlling the rotating shaft 2 to rotate to different angles, the air outlet 311 can achieve closed operation, simultaneous airflow from top and bottom, individual top airflow, and individual bottom airflow. By adjusting the rotation angle of the rotating shaft 2, the airflow volume of the air outlet 311 can be adjusted. The air outlet 311 has a large adjustment range for airflow direction, airflow volume, and airflow distance, resulting in significant air guiding effect and diverse airflow modes to meet different user needs. The structure and control method are simple, occupying little space, with minimal vibration and stable movement. It solves the problems of narrow adjustable airflow direction and limited airflow modes of a single air guide vane, and addresses the issues of complex structure, cumbersome control process, and unstable movement of multiple air guide vanes.

[0060] To address the issue of high airflow resistance at the connection between the air guide plate and the rotating shaft 2, leading to airflow loss, this embodiment proposes that both sides of each air guide plate in the thickness direction have an airfoil-like structure, and the connection between each air guide plate and the rotating shaft 2 is smoothly transitioned. This reduces airflow resistance, optimizes the airflow path, reduces airflow loss, enables wide-range and long-distance air delivery, ensures uniform and sufficient airflow, and improves air delivery comfort.

[0061] To address the issue of a small air delivery area when using a guide vane for directional air delivery, this embodiment proposes using multiple guide vanes of different sizes in combination to increase the air delivery area.

[0062] To address the issue of airflow comfort, each air guide plate has raised structures on both sides along its thickness direction, which creates a turbulence effect, preventing large areas of cold air from blowing directly on the surface and enhancing comfort.

[0063] In addition, the total number of air guides is n; among two adjacent air guides, one air guide has a width of b1 and the other air guide has a width of b2, and the difference in width between the two air guides is Δb = b1 - b2.

[0064] The angle between two adjacent air guides is related to both n and Δb; the more air guides there are, the smaller the angle between two adjacent air guides; the greater the difference in width Δb between two adjacent air guides, the larger the angle between two adjacent air guides.

[0065] To address the need for the air guide plate to achieve both multiple air outlet methods and closure, this embodiment proposes that the air guide plate device further include a first drive mechanism and a second drive mechanism. The first drive mechanism includes a first drive motor, which is driven and connected to the rotating shaft 2, driving the rotating shaft 2 and multiple air guide plates to rotate, so that the air outlet 311 can achieve air outlets in different directions. Specifically, the output shaft of the first drive motor is directly driven and connected to the rotating shaft 2. According to the structure and setting position of the multiple air guide plates, the first drive motor is controlled to rotate at different angles to achieve different air outlet methods.

[0066] The second drive mechanism includes a second drive motor, a first transmission component 371, and a second transmission component 372. The second drive motor is driven by the first transmission component 371, and the second transmission component 372 is driven by the first transmission component 371. The first drive motor and multiple air guide plates are mounted on the second transmission component 372. The second drive motor drives the first transmission component 371 to move, and through the transmission action of the second transmission component 372, the multiple air guide plates open or close the air outlet 311. Specifically, an air outlet frame is provided at the air outlet 311, and multiple limiting components 38 are provided on the air outlet frame. The multiple limiting components 38 are arranged alternately to form an arc-shaped slide rail. The first transmission component 371 is a gear, which is driven by the second drive motor. The second transmission component 372 is an arc-shaped rack, which is embedded in the arc-shaped slide rail. The first drive motor and multiple air guide plates are located at the end of the arc-shaped rack near the air outlet 311.

[0067] When the second drive motor drives the gear to rotate, the arc-shaped rack slides along the arc-shaped slide rail, thereby driving the first drive motor and multiple air guide plates to move towards the inside of the air outlet 311, so that the multiple air guide plates close the air outlet 311, or drive the first drive motor and multiple air guide plates to move towards the outside of the air outlet 311, so that the multiple air guide plates open the air outlet 311; when the air outlet 311 is opened, the first drive motor drives the rotating shaft 2 to rotate, so that the multiple air guide plates rotate to different positions, thereby realizing different air outlet modes.

[0068] Air Conditioning

[0069] This embodiment also provides an air conditioner 3, which includes a bottom shell 31, a panel body 32, and the air guide plate device described in any of the above embodiments; the bottom shell 31 forms an air outlet 311, and the rotating shaft 2 is rotatably disposed at the air outlet 311; the bottom shell 31 and the panel body 32 form a cavity, and a volute 35 and a volute tongue 36 are formed inside the cavity, and the volute 35 and the volute tongue 36 form an air duct, and an evaporator 33 is disposed on the lower side of the air inlet end of the air duct, and a cross-flow fan blade 34 is disposed on the lower side of the evaporator 33; the air outlet end of the air duct is connected to the air outlet 311;

[0070] By controlling the rotation of the shaft 2, different air outlet patterns can be produced by the air conditioner 3. Combined with the air conditioner 3's own operating mode, different effects can be achieved, thus improving the user experience.

[0071] Specifically, the multiple air guide plates include a first air guide plate 11, a second air guide plate 12 and a third air guide plate 13, wherein the width of the first air guide plate 11 is smaller than the width of the second air guide plate 12 and the width of the third air guide plate 13 is smaller than the width of the third air guide plate 13.

[0072] The angle between the surface of the first air guide plate 11 and the surface of the second air guide plate 12 is α, the angle between the surface of the second air guide plate 12 and the surface of the third air guide plate 13 is β, and the angle between the surface of the third air guide plate 13 and the surface of the first air guide plate 11 is γ; satisfying α+β+γ=360°.

[0073] It should be noted that the included angle between two adjacent air guide plates is not limited and can be set according to actual needs.

[0074] By controlling the rotation of the shaft 2, the second air guide plate 12 and the third air guide plate 13 can be used in combination, or any one of the second air guide plate 12 and the third air guide plate 13 can be used in combination with the first air guide plate 11. During the rotation of the shaft 2, the air outlet 311 can be closed, air can be discharged from the top and bottom at the same time, air can be discharged from the top independently, and air can be discharged from the bottom independently.

[0075] <Control Methods>

[0076] like Figures 2a to 2i As shown, this embodiment also provides a control method for the air conditioner 3 described above, the control method including:

[0077] S1. Determine the current position of multiple air guide plates based on the current state of the air outlet 311;

[0078] S2. Determine the target positions of multiple air guide plates based on the target status of air outlet 311;

[0079] S3. Determine the target rotation angle of the rotating shaft 2 based on the current and target positions of the multiple air guide vanes;

[0080] S4. Control the rotation of shaft 2 to the target rotation angle.

[0081] Furthermore, the current state and the target state of the air outlet 311 are both any of the states of the air outlet 311, including the initial state, the upper air outlet state, the lower air outlet state, and the simultaneous upper and lower air outlet state.

[0082] S2 includes:

[0083] When the air outlet 311 is in the initial state, the first air guide plate 11 is located outside the air outlet 311, and the surface of the first air guide plate 11 is parallel to the preset reference line 39. The second air guide plate 12 is close to the lower edge of the air outlet 311, and the third air guide plate 13 is close to the upper edge of the air outlet 311. The preset reference line 39 is set obliquely downward from the inner side of the air outlet 311 to the outer side of the air outlet 311.

[0084] When the air outlet 311 is in the upward air outlet state, the first air guide plate 11 is close to the upper edge of the air outlet 311, the second air guide plate 12 is located on the outside of the air outlet 311, and the third air guide plate 13 is close to the lower edge of the air outlet 311.

[0085] When the air outlet 311 is in the downward air outlet state, the first air guide plate 11 is close to the lower edge of the air outlet 311, the second air guide plate 12 is close to the upper edge of the air outlet 311, and the third air guide plate 13 is located on the outside of the air outlet 311.

[0086] When the air outlet 311 is in a state of simultaneous air outlet from the top and bottom, the second air guide plate 12 is away from the upper or lower edge of the air outlet 311, and the third air guide plate 13 is away from the lower or upper edge of the air outlet 311.

[0087] It should be noted that the initial state of the air outlet 311 can also be other states, which can be set according to actual needs.

[0088] Furthermore, the current state of air outlet 311 is the initial state, and S3 includes:

[0089] When the target state of the air outlet 311 is the upward air outlet state, the target rotation angle of the rotating shaft 2 is θ=α;

[0090] When the target state of the air outlet 311 is the downward air outlet state, the target rotation angle of the rotating shaft 2 is θ=α+β;

[0091] When the target state of the air outlet 311 is that the air outlet is simultaneously venting from the top and bottom, the target rotation angle of the rotating shaft 2 is θ < α, α < θ < α + β, and α + β < θ < 360°.

[0092] In addition, the state of the air outlet 311 also includes a closed state; when the air outlet 311 is in the closed state, the first air guide plate 11 is located inside the air outlet 311, the second air guide plate 12 is close to the upper edge of the air outlet 311, and the third air guide plate 13 is close to the lower edge of the air outlet 311.

[0093] When the current state of the air outlet 311 is the initial state and the target state of the air outlet 311 is the closed state, the target rotation angle θ of the rotating shaft 2 is α + 0.5*β.

[0094] Specifically, the three air guide vanes can rotate 360° around the rotating shaft 2. The rotating shaft 2 can rotate clockwise or counterclockwise, thus achieving different air outlet patterns. The counterclockwise rotation is used as an example:

[0095] like Figure 2a As shown, the first air guide plate 11 is located outside the air outlet 311, and the surface of the first air guide plate 11 is parallel to the preset reference line 39. The second air guide plate 12 is close to the lower edge of the air outlet 311, and the third air guide plate 13 is close to the upper edge of the air outlet 311. At this time, the air outlet 311 is in the initial state. The preset reference line 39 is set obliquely downward from the inner side of the air outlet 311 to the outer side of the air outlet 311. The target rotation angle θ of the rotating shaft 2 is defined as 0°.

[0096] like Figure 2b As shown, the rotating shaft 2 rotates counterclockwise, and the target rotation angle θ of the rotating shaft 2 gradually increases. The third air guide plate 13 gradually moves away from the upper edge of the air outlet 311, and the upper side of the air outlet 311 is opened. The second air guide plate 12 gradually moves away from the lower edge of the air outlet 311, and the lower side of the air outlet 311 is opened. 0° < θ < α. At this time, the air outlet 311 is in a state of simultaneous airflow from the top and bottom. The third air guide plate 13 acts as a diversion air guide plate, which diverts the airflow. A portion of the airflow flows along the surface of the third air guide plate 13 and the first air guide plate 11, while another portion of the airflow flows along the surface of the third air guide plate 13 and the second air guide plate 12, thus achieving the effect of simultaneous airflow from the top and bottom of the air outlet 311.

[0097] like Figure 2c As shown, the rotating shaft 2 continues to rotate counterclockwise, and the target rotation angle θ of the rotating shaft 2 gradually increases. The third air guide plate 13 gradually approaches the lower edge of the air outlet 311, and the lower side of the air outlet 311 is gradually closed. The first air guide plate 11 gradually approaches the upper edge of the air outlet 311. When the target rotation angle θ of the rotating shaft 2 is α, the lower side of the air outlet 311 is completely closed. Since the width of the first air guide plate 11 is small, the upper side of the air outlet 311 is not completely closed at this time, so the air outlet 311 can only exhaust air from the top.

[0098] like Figure 2dAs shown, the rotating shaft 2 continues to rotate counterclockwise, and the target rotation angle θ of the rotating shaft 2 gradually increases. The third air guide plate 13 gradually moves away from the lower edge of the air outlet 311, and the lower side of the air outlet 311 gradually opens. The first air guide plate 11 gradually moves away from the upper edge of the air outlet 311, α < θ < α + β. At this time, the first air guide plate 11 acts as a diversion air guide plate, forming a diversion effect on the airflow. A part of the airflow flows along the surface of the first air guide plate 11 and the second air guide plate 12, and another part of the airflow flows along the surface of the first air guide plate 11 and the third air guide plate 13, realizing the effect of air outlet 311 simultaneously exiting from the top and bottom. This state is similar to... Figure 2b The difference between the states is that the first air guide plate 11 is smaller in size in this state, resulting in less resistance to airflow and a larger air volume.

[0099] like Figure 2e As shown, the rotating shaft 2 continues to rotate counterclockwise, and the target rotation angle θ of the rotating shaft 2 gradually increases. The third air guide plate 13 gradually moves away from the lower edge of the air outlet 311, and the lower side of the air outlet 311 is opened. The second air guide plate 12 gradually approaches the upper edge of the air outlet 311. When the target rotation angle θ of the rotating shaft 2 is α + 0.5*β, the air outlet area on the upper side and the lower side of the air outlet 311 are equal, and the difference in air volume is small. Figure 2i As shown, in some embodiments, the second drive motor is controlled to drive the first transmission component 371 to move, so that the second transmission component 372 drives multiple air guide plates to move towards the inside of the air outlet 311 until the second air guide plate 12 is close to the upper edge of the air outlet 311 and the third air guide plate 13 is close to the lower edge of the air outlet 311, thus closing the air outlet 311.

[0100] like Figure 2f As shown, the rotating shaft 2 continues to rotate counterclockwise, and the target rotation angle θ of the rotating shaft 2 gradually increases. The first air guide plate 11 gradually approaches the lower edge of the air outlet 311, and the second air guide plate 12 gradually approaches the upper edge of the air outlet 311. The upper side of the air outlet 311 is gradually closed. α+0.5*β<θ<α+β. At this time, the first air guide plate 11 acts as a diversion air guide plate, forming a diversion effect on the airflow. A part of the airflow flows along the surface of the first air guide plate 11 and the second air guide plate 12, and another part of the airflow flows along the surface of the first air guide plate 11 and the third air guide plate 13, achieving the effect of air outlet 311 simultaneously venting from the top and bottom.

[0101] like Figure 2gAs shown, the rotating shaft 2 continues to rotate counterclockwise, and the target rotation angle θ of the rotating shaft 2 gradually increases. The second air guide plate 12 gradually approaches the upper edge of the air outlet 311, and the upper side of the air outlet 311 is gradually closed. The first air guide plate 11 gradually approaches the lower edge of the air outlet 311. When the target rotation angle θ of the rotating shaft 2 is α + β, the upper side of the air outlet 311 is completely closed. Since the width of the first air guide plate 11 is small, the lower side of the air outlet 311 is not completely closed at this time, so the air outlet 311 can only emit air downwards.

[0102] like Figure 2h As shown, the rotating shaft 2 continues to rotate counterclockwise, and the target rotation angle θ of the rotating shaft 2 gradually increases. The first air guide plate 11 gradually moves away from the lower edge of the air outlet 311, and the third air guide plate 13 gradually moves closer to the upper edge of the air outlet 311. α+β<θ<360°. At this time, the second air guide plate 12 acts as a diversion air guide plate, forming a diversion effect on the airflow. A part of the airflow flows along the surface of the second air guide plate 12 and the third air guide plate 13, and another part of the airflow flows along the surface of the second air guide plate 12 and the first air guide plate 11, achieving the effect of air outlet 311 simultaneously venting from the top and bottom.

[0103] In summary, by using the air guide plate device of this application, various air outlet modes and air volume adjustments can be achieved by controlling the target rotation angle of the rotating shaft 2. In the high air volume mode, the first air guide plate 11 can be used as a diversion air guide plate. In the simultaneous air outlet mode, the target rotation angle of the rotating shaft 2 can be set to a range of α < θ < α + β. In the low air volume mode and the simultaneous air outlet mode, the target rotation angle of the rotating shaft 2 can be set to a range of 0° < θ < α or α + β < θ < 360°. After the air conditioner 3 is turned on, the rotating shaft 2 can rotate to a certain angle and remain stationary to achieve constant angle air supply, or it can reciprocate at a certain frequency to achieve dynamic changes in the air supply range.
