Description

Technical Field

[0001] This invention belongs to the field of air treatment technology, and particularly relates to an air guiding device, an air conditioner, and a control method. Background Technology

[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 limited range of airflow patterns, making it difficult to meet diverse user needs. Other systems use multiple air guide vanes at the outlet, but each vane requires independent control, leading to complex structures, cumbersome control processes, poor airflow smoothing, and the tendency for airflow to blow directly at the user. Summary of the Invention

The second drive motor is drivenly connected to the first transmission component, and the second transmission component is transmitted through the first transmission component. The first drive motor and a plurality of the air guide components are disposed on the second transmission component.

[0017] The present invention also provides an air conditioner, the air conditioner including a bottom shell and an air guide device as described in any of the above claims; the bottom shell is formed with an air outlet, and the rotating shaft is rotatably disposed at the air outlet.

[0018] The present invention also provides a control method for the air conditioner described above, the control method comprising:

[0019] The current positions of the multiple air guide components are determined based on the current state of the air outlet;

[0020] The target positions of multiple air guide components are determined based on the target state of the air outlet.

[0021] The target rotation angle of the rotating shaft is determined based on the current and target positions of the multiple air guide components;

[0022] Control the rotation angle of the target shaft.

[0023] Further optionally, the current state and the target state of the air outlet are both any one of the states of the air outlet, including the state of air outlet with gentle airflow from both top and bottom, the state of air outlet with gentle airflow from top, the state of air outlet with gentle airflow from bottom, and the state of air outlet with gentle airflow from a specific area.

[0024] Determining the target positions of multiple air guides based on the target state of the air outlet includes:

[0025] When the air outlet is in a soft airflow state with airflow coming out from both the top and bottom, the first air guide is located outside the air outlet, and the surface of the first air guide is parallel to the preset reference line. The second air guide is close to the upper edge of the air outlet, and the third air guide is close to the lower edge of the air outlet. The preset reference line is set obliquely downward from the inner side of the air outlet to the outer side of the air outlet.

[0026] When the air outlet is in the downward airflow soft airflow state, the first air guide is close to the upper edge of the air outlet, the second air guide is close to the lower edge of the air outlet, and the third air guide is located on the outside of the air outlet.

[0027] When the air outlet is in the upward airflow soft airflow state, the first air guide is close to the lower edge of the air outlet, the second air guide is located on the outside of the air outlet, and the third air guide is close to the upper edge of the air outlet.

[0028] When the air outlet is in a localized soft airflow state, the first air guide is located inside the air outlet, the second air guide is near the lower edge of the air outlet, and the third air guide is near the upper edge of the air outlet; or the third air guide is located inside the air outlet, the first air guide is near the lower edge of the air outlet, and the second air guide is near the upper edge of the air outlet; or the second air guide is located inside the air outlet, the first air guide is near the upper edge of the air outlet, and the third air guide is near the lower edge of the air outlet.

[0029] Further optionally, the angle between the plate surface of the first air guide and the center surface of the second air guide is α, the angle between the center surface of the second air guide and the center surface of the third air guide is β, and the angle between the center surface of the third air guide and the plate surface of the first air guide is γ; satisfying α+β+γ=360°;

[0030] The current state of the air outlet is a gentle airflow state with simultaneous upward and downward airflow, and the target rotation angle θ of the rotating shaft is 0°; determining the target rotation angle of the rotating shaft based on the current and target positions of the multiple air guides includes:

[0031] When the target state of the air outlet is a downward airflow soft wind state, the target rotation angle of the rotating shaft is θ=α;

[0032] When the target state of the air outlet is the upward airflow soft wind state, the target rotation angle of the rotating shaft is θ=α+β;

[0033] When the target state of the air outlet is a localized gentle airflow state, the target rotation angle of the rotating shaft is 0° < θ < α, α < θ < α + β, and α + β < θ < 360°.

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

[0035] (1) Multiple air guides can rotate synchronously with the rotating shaft. When the rotating shaft is rotated to different angles, the air outlet can achieve simultaneous upper and lower airflow, single upper airflow, and single lower airflow. Combined with the turbulence structure, different soft airflow effects are achieved, and the turbulence effect is diversified, improving the comfort of the airflow. The air outlet has a large range of adjustment for airflow direction, airflow volume, and airflow distance, 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 airflow direction adjustment range and single airflow mode of a single air guide plate, and solves the problems of complex structure, cumbersome control process, and poor soft airflow effect of multiple air guide plates, avoiding the problem of airflow blowing directly on users.

[0036] (2) Both sides of the first air guide are airfoil-shaped structures in the thickness direction. The air guide and the shaft are connected smoothly, 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.

[0037] (3) Different combinations of the three air guides can achieve more turbulence effects; determine the target rotation angle of the rotating shaft according to the current position and target position of the air guides, and control the target rotation angle of the rotating shaft to make the air outlet in the target state.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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 resulting in a poor user experience. Other ventilation equipment has multiple air guide components at the air outlet, but each air guide plate needs to be controlled independently, making the air guiding device complex in structure, cumbersome in control process, large in space occupation, and unstable in movement.

[0056] This invention creatively provides an air guiding device for ventilation equipment. The ventilation equipment has an air outlet, and the air guiding device includes a rotating shaft and air guiding components. The rotating shaft is rotatably mounted at the air outlet, and multiple air guiding components are arranged alternately along the circumference of the rotating shaft. Among the multiple air guiding components, at least one air guiding component has a turbulence structure, and another air guiding component has a plate-like structure with both sides in the thickness direction having an airfoil-like structure. When the rotating shaft rotates, the multiple air guiding components can rotate synchronously. By controlling the rotating shaft to different angles, the air outlet can achieve simultaneous upward and downward airflow, upward airflow alone, and downward airflow alone. Combined with the turbulence structure, different gentle breeze effects are achieved, resulting in diversified turbulence effects and improved airflow comfort. The structure and control method are simple, occupy little space, and have stable movement.

[0057] <Air guiding device>

[0058] like Figure 1a , Figure 1b and Figure 1cAs shown, this embodiment provides an air guiding device for ventilation equipment, particularly for a wall-mounted air conditioner 3. The ventilation equipment has an air outlet 311, and the air guiding device is disposed at the air outlet 311. The air guiding device includes a rotating shaft 2 and air guiding components. The rotating shaft 2 is rotatably disposed at the air outlet 311, and the axis of the rotating shaft 2 is aligned with the length direction of the air outlet 311. Multiple air guiding components are arranged alternately on the rotating shaft 2 along its circumference. At least one of the multiple air guiding components has a turbulence-inducing structure. Another air guide is a plate-shaped structure, and both sides of the air guide in the thickness direction are airfoil-shaped structures; when the rotating shaft 2 rotates, multiple air guides can rotate synchronously; the number of air guides is not limited, but the number of air guides is greater than 2. In this embodiment, the air guides include a first air guide 11, a second air guide 12, and a third air guide 13; the second air guide 12 has a first turbulence structure, the third air guide 13 has a second turbulence structure, and the turbulence direction of the first turbulence structure is different from the turbulence direction of the second turbulence structure;

[0059] Furthermore, the first turbulence structure is a first turbulence column 121, which extends along the length direction of the second air guide 12; the first turbulence column 121 includes a plurality of them, and the plurality of first turbulence columns 121 are arranged alternately along the width direction of the second air guide 12.

[0060] The second turbulence structure is a second turbulence column 131, which extends along the width direction of the third air guide 13; the second turbulence column 131 includes a plurality of them, and the plurality of second turbulence columns 131 are arranged alternately along the length direction of the third air guide 13.

[0061] In summary, multiple air guide components can rotate synchronously with the rotating shaft 2. By controlling the rotating shaft 2 to different angles, the air outlet 311 can achieve simultaneous upward and downward airflow, upward airflow alone, and downward airflow alone. Combined with the turbulence structure, different gentle breeze effects are achieved, resulting in diverse turbulence effects and improved airflow comfort. The airflow volume of the air outlet 311 can be adjusted by adjusting the rotation angle of the rotating shaft 2. The air outlet 311 has a wide range of adjustment for airflow direction, airflow volume, and air delivery distance, providing significant air guiding effect and diverse airflow modes to meet different user needs. The structure and control method are simple and occupy a large area. It features a small footprint, minimal vibration, and stable movement; it solves the problems of narrow adjustable airflow direction and limited airflow mode of a single air guide plate, as well as the complex structure, cumbersome control process, and poor gentle breeze effect of multiple air guide plates, and avoids the problem of airflow blowing directly on users; both sides of the air guide plate in the thickness direction have an airfoil-like structure, and the connection between each air guide component and the rotating shaft 2 is smoothly transitioned; it reduces air resistance when air passes through, optimizes the airflow path, reduces airflow loss, and can achieve large-area and long-distance air delivery, with uniform air delivery and sufficient airflow, improving air delivery comfort.

[0062] It should be noted that different structures of turbulence columns can be set on the same air guide. One type of turbulence column extends along the length of the air guide, while another type extends along the width of the air guide. The structure of the turbulence column is not limited to a column structure; it can be a plate structure or a spherical structure. The cross-sectional shape of the turbulence column can be circular, triangular, rectangular, polygonal, elliptical, or wavy.

[0063] To address the issue of poor wind-softening effect of the turbulence structure, this embodiment proposes that the first turbulence column 121 and the second turbulence column 131 are both cylindrical structures; the axial distance between two adjacent first turbulence columns 121 is s1, and the diameter of the first turbulence column 121 is d1, satisfying 1.5*d1<s1<2.5*d1;

[0064] The axial spacing between two adjacent second turbulence columns 131 is s2, and the diameter of the second turbulence column 131 is d2, satisfying 1.5*d2<s2<2.5*d2.

[0065] Furthermore, the first air guide 11 is a plate structure, while the second air guide 12 and the third air guide 13 are both frame structures. Along the length of the second air guide 12, multiple first mounting holes are formed on both sides of the second air guide 12. The two ends of the first turbulence column 121 are respectively set in the corresponding first mounting holes, and the position of the first turbulence column 121 on the second air guide 12 is adjustable.

[0066] Along the width direction of the third air guide 13, multiple second mounting holes are formed on both sides of the third air guide 13. The two ends of the second turbulence column 131 are respectively set in the corresponding second mounting holes. The position of the second turbulence column 131 on the third air guide 13 is adjustable.

[0067] Furthermore, the length directions of the air outlet, the first air guide 11, the second air guide 12, and the third air guide 13 are all aligned with the axis of the rotating shaft 2; the plate surface of the first air guide 11, the center surface of the second air guide 12, and the center surface of the third air guide 13 all pass through the axis of the rotating shaft 2.

[0068] like Figure 2g As shown in this embodiment, the air guiding device further includes a first driving mechanism and a second driving mechanism; the first driving mechanism includes a first driving motor, which is drivenly connected to the rotating shaft 2 and drives the rotating shaft 2 and multiple air guiding components to rotate, so that the air outlet 311 can achieve air outlet in different directions; specifically, the output shaft of the first driving motor is directly drivenly connected to the rotating shaft 2, and the first driving motor is controlled to rotate at different angles according to the structure and setting position of the multiple air guiding components, so as to achieve different air outlet modes and gentle wind states;

[0069] 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 guides 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 guides move away from or closer to 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 guides are located at the end of the arc-shaped rack near the air outlet 311.

[0070] 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 guides to move towards the inside of the air outlet 311, or driving the first drive motor and multiple air guides to move towards the outside of the air outlet 311; when the multiple air guides move away from the air outlet 311, the first drive motor drives the rotating shaft 2 to rotate, causing the multiple air guides to rotate to different positions, which can realize different air outlet modes and gentle breeze states.

[0071] Air Conditioning

[0072] This embodiment also provides an air conditioner 3, which includes a bottom shell 31, a panel body 32, and the air guiding 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;

[0073] 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.

[0074] Specifically, the multiple air guides include a first air guide 11, a second air guide 12, and a third air guide 13;

[0075] The angle between the plate surface of the first air guide 11 and the center surface of the second air guide 12 is α, the angle between the center surface of the second air guide 12 and the center surface of the third air guide 13 is β, and the angle between the center surface of the third air guide 13 and the plate surface of the first air guide 11 is γ; satisfying α+β+γ=360°.

[0076] It should be noted that the included angle between two adjacent first air guides 11 is not limited and can be set according to actual needs.

[0077] By controlling the rotation of the shaft 2, the second air guide 12 and the third air guide 13 can be used in combination, or any one of the second air guide 12 and the third air guide 13 can be used in combination with the first air guide 11. During the rotation of the shaft 2, the air outlet 311 can achieve effects such as simultaneous air outlet from the top and bottom, independent air outlet from the top, and independent air outlet from the bottom, as well as different gentle wind states.

[0078] <Control Methods>

[0079] like Figures 2a to 2g As shown, this embodiment also provides a control method for the air conditioner 3 described above, the control method including:

[0080] S1. Determine the current position of multiple air guide components based on the current state of the air outlet 311;

[0081] S2. Determine the target positions of multiple air guide components based on the target status of the air outlet 311;

[0082] S3. Determine the target rotation angle of the rotating shaft 2 based on the current and target positions of multiple air guide components;

[0083] S4. Control the rotation of shaft 2 to the target rotation angle.

[0084] Furthermore, the current state and the target state of the air outlet 311 are both any one of the states of the air outlet 311. The states of the air outlet 311 include the state of simultaneous upper and lower air outlet gentle wind, the state of upper air outlet gentle wind, the state of lower air outlet gentle wind, and the state of partial air outlet gentle wind.

[0085] S2 includes:

[0086] When the air outlet is in a soft airflow state with airflow coming out from both the top and bottom, the first air guide 11 is located on the outside of the air outlet, and the plate surface of the first air guide 11 is parallel to the preset reference line. The second air guide 12 is close to the upper edge of the air outlet, and the third air guide 13 is close to the lower edge of the air outlet. The preset reference line 39 is set obliquely downward from the inside of the air outlet to the outside of the air outlet.

[0087] When the air outlet is in the downward airflow soft airflow state, the first air guide 11 is close to the upper edge of the air outlet, the second air guide 12 is close to the lower edge of the air outlet, and the third air guide 13 is located on the outside of the air outlet.

[0088] When the air outlet is in the upward airflow soft airflow state, the first air guide 11 is close to the lower edge of the air outlet, the second air guide 12 is located on the outside of the air outlet, and the third air guide 13 is close to the upper edge of the air outlet.

[0089] When the air outlet is in a localized gentle airflow state, the first air guide 11 is located inside the air outlet, the second air guide 12 is near the lower edge of the air outlet, and the third air guide 13 is near the upper edge of the air outlet; or the third air guide 13 is located inside the air outlet, the first air guide 11 is near the lower edge of the air outlet, and the second air guide 12 is near the upper edge of the air outlet; or the second air guide 12 is located inside the air outlet, the first air guide 11 is near the upper edge of the air outlet, and the third air guide 13 is near the lower edge of the air outlet.

[0090] Furthermore, the current state of air outlet 311 is a gentle breeze state with simultaneous airflow from both the top and bottom, and S3 includes:

[0091] When the target state of the air outlet is the downward airflow soft wind state, the target rotation angle of the rotating shaft 2 is θ=α;

[0092] When the target state of the air outlet is the upward airflow soft wind state, the target rotation angle of the rotating shaft 2 is θ=α+β;

[0093] When the target state of the air outlet is a localized soft airflow state, the target rotation angle of the rotating shaft 2 is 0° < θ < α, α < θ < α + β, and α + β < θ < 360°.

[0094] Specifically, such as Figure 2a As shown, the target rotation angle θ = α of the rotating shaft 2 is such that the first air guide 11 is close to the upper edge of the air outlet, and the upper side of the air outlet is closed; this angle can be used as the angle when the air conditioner 3 is closed, which can prevent dust from entering from the front of the panel 32; the second air guide 12 is close to the lower edge of the air outlet, and due to the presence of the first turbulence column 121, the lower side of the air outlet is not completely closed; when the air conditioner 3 is turned on, the airflow flows out after passing through the second air guide 12, and due to the action of the first turbulence column 121, a radial turbulence effect can be obtained; the air conditioner 3 air outlet mode is a downward air outlet soft wind state.

[0095] like Figure 2bAs shown, the target rotation angle θ of the rotating shaft 2 satisfies α < θ < α + β. The upper and lower sides of the air outlet gradually open. The first air guide 11 acts as a diversion air guide, creating a diversion effect on the airflow. Part of the airflow flows along the surfaces of the first air guide 11 and the third air guide 13, part of the airflow flows along the surfaces of the first air guide 11 and the second air guide 12, and some airflow passes through the second air guide 12 and the third air guide 13 respectively. The airflow passing through the second air guide 12 is dispersed radially by the first turbulence column 121; the airflow passing through the third air guide 13 is dispersed axially by the second turbulence column 131. These two dispersed airflows mix in the area between the second air guide 12 and the third air guide 13, resulting in a stronger dispersion effect. From this angle, the air conditioner 3 can simultaneously blow air from the top and bottom to ensure air volume. The area between the second air guide 12 and the third air guide 13 blows out a mixed, soft airflow, which can prevent the airflow from blowing directly on the human body and improve comfort.

[0096] like Figure 2c As shown, the target rotation angle θ of the rotating shaft 2 satisfies θ=α+β. The first air guide 11 is close to the lower edge of the air outlet, and the third air guide 13 is close to the upper edge of the air outlet. The first air guide 11 completely seals the lower side of the air outlet. Due to the presence of the second turbulence column 131, the upper side of the air outlet is not completely sealed. When the air conditioner 3 is turned on, the airflow flows out after passing through the third air guide 13. Due to the effect of the second turbulence column 131, an axial turbulence effect can be obtained. The air conditioner 3's air outlet mode is a top-outlet soft wind state.

[0097] like Figure 2d As shown, the target rotation angle θ of the rotating shaft 2 satisfies α+β<θ<360°. The third air guide 13 acts as a diversion air guide, creating a diversion effect on the airflow. Part of the airflow flows along the surfaces of the third air guide 13 and the first air guide 11, part of the airflow flows along the surfaces of the third air guide 13 and the second air guide 12, and some airflow passes through the second air guide 12 and flows out. The airflow passing through the second air guide 12 is dispersed radially by the action of the first turbulence column 121. At this angle, the air conditioner 3 can achieve simultaneous airflow from the top and bottom, ensuring the airflow volume. A gentle breeze is blown out in the area between the first air guide 11 and the second air guide 12.

[0098] like Figure 2eAs shown, the target rotation angle θ of the rotating shaft 2 satisfies θ=0°. The third air guide 13 is close to the lower edge of the air outlet, and the second air guide 12 is close to the upper edge of the air outlet. Neither the upper nor lower air outlet is closed. When the air conditioner 3 is turned on, the airflow passing through the second air guide 12 is dispersed radially by the first turbulence column 121. The airflow passing through the third air guide 13 is dispersed axially by the second turbulence column 131. The two dispersed airflows are separated by the first air guide 11 and will not mix. At this angle, the air conditioner 3 can achieve a gentle breeze throughout the entire area.

[0099] like Figure 2f As shown, the target rotation angle θ of the rotating shaft 2 satisfies 0° < θ < α. The second air guide 12 acts as a diversion air guide, creating a diversion effect on the airflow. Part of the airflow flows along the surface of the second air guide 12 and the first air guide 11, part of the airflow flows along the surface of the second air guide 12 and the third air guide 13, and some airflow passes through the third air guide 13 and flows out. The airflow passing through the third air guide 13 is dispersed axially by the action of the second turbulence column 131. At this angle, the air conditioner 3 can achieve simultaneous airflow from the top and bottom to ensure the airflow volume. A gentle breeze is blown out in the area between the first air guide 11 and the third air guide 13.

[0100] In summary, by using this type of air guiding device and controlling the target rotation angle of the rotating shaft 2, various air outlet modes and air volume effects can be achieved; single-outlet gentle airflow mode: downward gentle airflow, upward gentle airflow; zone gentle airflow: bidirectional turbulent gentle airflow, unidirectional turbulent gentle airflow; and full-area gentle airflow mode. Specifically, when the target rotation angle θ of the rotating shaft 2 satisfies α < θ < α + β, the bidirectional turbulent gentle airflow angle changes, and the air volume ratio of the upper and lower outlets changes; when the target rotation angle θ of the rotating shaft 2 satisfies α + β < θ < 360°, the unidirectional turbulent gentle airflow angle changes, and the air volume ratio of the upper and lower outlets changes; when the target rotation angle θ of the rotating shaft 2 satisfies 0° < θ < α, the unidirectional turbulent gentle airflow angle changes, and the air volume ratio of the upper and lower outlets changes; and 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.
