Description

Technical Field

[0001] This invention relates to the field of air conditioning control technology, and in particular to an air guiding device. Background Technology

[0002] An air conditioner, or air conditioner, is a device that uses artificial means to quickly adjust and control parameters such as ambient temperature within a building or structure.

[0003] When regulating the ambient temperature, the air conditioner forces the temperature to be adjusted by sending out cold or hot air from the air outlet into the ambient space, thereby improving people's physical comfort.

[0004] However, the air outlets of current air conditioners are fixed, and air can only be vented through one outlet. The air volume varies depending on the distance from the outlet, making it inconvenient for users at different distances. Summary of the Invention

[0005] To address at least one problem existing in the prior art, according to one aspect of the present invention, an air guiding device is provided, comprising: a main air outlet for blowing out airflow; an air guiding duct surrounding the main air outlet for conveying the airflow blown out from the main air outlet, the air guiding duct having a plurality of sub-air outlets arranged separately from each other; and a plurality of first wind deflectors arranged separately from each other in the inner cavity of the air guiding duct, the first wind deflectors being capable of closing or opening relative to the inner cavity of the air guiding duct, the first wind deflectors in the closed state being used to block the airflow from flowing away from the main air outlet, so that the airflow flows out from the sub-air outlets in the direction close to the main air outlet.

[0006] In this way, by setting up an air duct around the main air outlet, the airflow blown out of the main air outlet is collected into the air duct. Since the air duct is divided into multiple sub-air outlets, each with a different direction from the main air outlet, the airflow can be blown out from each sub-air outlet, thus reaching people at different distances. At the same time, multiple first wind deflectors are set in the inner cavity of the air duct. The first wind deflectors can be closed or opened relative to the inner cavity of the air duct. When the first wind deflector is closed relative to the inner cavity of the air duct, the airflow can only flow out from the sub-air outlets closer to the main air outlet. Thus, the first wind deflectors restrict the airflow from flowing further backward. By controlling whether the airflow can flow to the sub-air outlets at different distances, the airflow can be directed to users at different distances.

[0007] In some embodiments, the air duct is a closed annular duct.

[0008] In this way, the airflow from the main air outlet can flow along the left and right sides into the air ducts, making the airflow delivery range wider. By transporting the airflow to various areas of the room through the air ducts, it can be used by more users.

[0009] In some embodiments, at least one second wind deflector is also included, which is disposed at the main air outlet and is movable relative to the inner cavity of the air guide duct to close or open the air outlet passage of the main air outlet.

[0010] In this way, by setting a second baffle on the left and / or right side of the main air outlet, it can cooperate with the first baffle to control the air outlet of different sections.

[0011] In some embodiments, the air duct includes a horizontal section and at least one curved section, the main air outlet is located on the horizontal section, and at least one sub-air outlet is provided on the curved section.

[0012] In this way, by setting at least part of the air duct as a curved section with different heights and setting sub-air outlets on the curved section, air can be discharged to different heights to meet the requirements of users at different heights, or to accommodate standing postures at higher heights or sitting or lying postures at lower heights, thus improving the practicality of the air duct.

[0013] In some embodiments, the curved section is parabolic in shape, and a sub-outlet is located at the apex of the parabola.

[0014] In this way, by setting up parabolic air ducts, the air can be positioned at different heights relative to the ground, allowing air to be discharged at different heights. Furthermore, by setting them opposite to the main air outlet, the airflow loss is reduced. The airflow first flows from the horizontal section and then to the curved section, thereby minimizing the loss of air force.

[0015] In some embodiments, the first windbreak is inclined relative to the air duct and inclined relative to the direction of the incoming airflow.

[0016] In this way, when the airflow hits the first wind deflector, the tilted first wind deflector can help to steer it, reducing wind force loss.

[0017] In some implementations, the first windbreak, which is in the closed state, is also used to close one of the sub-outlets located in the direction of the incoming wind.

[0018] This allows all the airflow to flow to the rear, increasing the airflow at the rear sub-outlets.

[0019] In some embodiments, multiple air-adjusting mechanisms are also included, with each of the sub-air outlets having an air-adjusting mechanism for adjusting the airflow direction at the sub-air outlet.

[0020] In this way, by setting up air-adjusting mechanisms at each sub-air outlet to adjust the airflow direction of that sub-air outlet, such as adjusting it to flow upward or downward, or to flow left or right, it is more convenient for users to use.

[0021] In some embodiments, the air regulating mechanism includes multiple air regulating components, which are arranged separately from each other. Each air regulating component includes an arc-shaped air guiding surface and a planar air guiding surface. Every two air regulating components form a group, and the two air regulating components in each group are arranged in a mirror image.

[0022] In this way, by setting the air regulating components to include an arc-shaped air guide surface, the airflow can achieve the Coanda effect on the arc-shaped air guide surface. The airflow flows along the surface of the arc-shaped air guide surface, and the cooperation of multiple air regulating components can achieve the effect of dispersing or concentrating airflow.

[0023] In some embodiments, the air regulating mechanism includes a second drive member for driving at least one of the air regulating elements to move.

[0024] In this way, by setting a second driving component to drive at least one air regulating component to move, different air outlet modes can be adjusted. Attached Figure Description

[0038] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings.

[0042] Please see Figures 1 to 5 The air guiding device 100 provided in the embodiment of the present invention includes a main air outlet 10, an air guiding duct 20 and a plurality of first wind deflectors 30.

[0043] Please see Figure 1 and Figure 2 The main air outlet 10 is used to blow out airflow; the air guide duct 20 surrounds the main air outlet 10 and is used to transport the airflow blown out from the main air outlet 10. The air guide duct 20 is provided with multiple sub-air outlets 21, which are separated from each other; multiple first wind deflectors 30 are separated from each other in the inner cavity of the air guide duct 20. The first wind deflectors 30 can be closed or opened relative to the inner cavity of the air guide duct 20. When the first wind deflector 30 is closed, it is used to block the airflow from flowing away from the main air outlet 10, so that the airflow flows out from the sub-air outlets 21 in the direction close to the main air outlet 30.

[0044] The aforementioned air guiding device 100, by setting an air guiding duct 20 around the main air outlet 10, collects the airflow blown out of the main air outlet 10 into the air guiding duct 20. Since the air guiding duct 20 is divided into multiple sub-air outlets 21, each with a different direction from the main air outlet 10, airflow can be blown out from each sub-air outlet 21, thus reaching people at different distances. Simultaneously, multiple air outlets are also divided within the inner cavity of the air guiding duct 20. The first wind deflector 30 can be closed or opened relative to the inner cavity of the air guide duct 20. When the first wind deflector 30 is closed relative to the inner cavity of the air guide duct 20, the airflow can only flow out from the sub-air outlet 21 near the main air outlet 30. Thus, the first wind deflector 30 restricts the airflow from continuing to flow backward. The first wind deflector 30 controls whether the airflow can flow to the sub-air outlet 21 at different distances, so as to control the airflow to blow to users at different distances.

[0045] In this embodiment, the main air outlet 10 can be the air outlet of a wall-mounted air conditioner indoor unit, the air outlet of a central air conditioner, or the air outlet of other air conditioning devices. The airflow generated by the indoor unit or the central air conditioner is blown out from the main air outlet 10 and flows into the room through the air duct 20.

[0046] Understandably, the air duct 20 can be supported indoors by a support device, or it can be installed on the wall, or it can be fully or partially embedded in the wall, and at this time the air outlet 21 is exposed from the wall to blow out airflow. The installation method of the air duct 20 is not limited here.

[0047] Specifically, in this embodiment, the main air outlet 10 is the air outlet of the wall-mounted air conditioner. The air duct 20 is described with the example of being installed on the wall. After the wall-mounted air conditioner is installed on the wall, the duct is installed around the outside of the air outlet. In this embodiment, the cross-sectional shape of the air duct 20 can be square, circular, or other polygonal shapes.

[0048] Please see Figure 1 In one embodiment of the present invention, the air duct 20 is a closed annular duct, so that the airflow blown out of the main air outlet 10 can flow into the air duct 20 along the left and right sides, making the airflow delivery range wider. The airflow is delivered to various areas of the room through the air duct 20, which can be used by more users.

[0049] Understandably, in other embodiments, the air duct 20 may not be designed as a closed loop. In this case, one end of the air duct 20 is wrapped around the main air outlet 10, and the other end is a free end, so that the airflow is delivered from only one duct. In this case, the airflow delivered in the duct can be greater, and a greater airflow can be blown out from each sub-air outlet 21.

[0050] Understandably, the extension length of the air duct 20 can be adjusted as needed. In order to blow out a larger volume of air in the sub-outlet 21, a shorter air duct 20 can be set, so that the airflow does not have to pass through a long air duct, reducing airflow loss and providing users with a larger volume of airflow. When it is necessary to blow to more users, a longer air duct 20 can be set, so that more sub-outlets 21 can be set on the air duct 20, and more users can be blown.

[0051] Understandably, when the air duct 20 is in a closed loop, the airflow can flow to the left and right sides of the main air outlet 10. When it is only necessary to flow to the left or right, the direction of the airflow needs to be controlled. Therefore, the air duct device 100 in this embodiment also includes at least one second baffle 40. The second baffle 40 is located at the main air outlet 10 and can move relative to the inner cavity of the air duct 20 to close or open the air outlet channel of the main air outlet 10. Thus, when the air duct 20 is in a closed loop, the airflow can be controlled to flow only from one side of the main air outlet 10.

[0052] Specifically, the second baffle 40 is located on the left and / or right side of the main air outlet 10. By placing the second baffle 40 on the left and / or right side of the main air outlet 10, it can cooperate with the first baffle 30 to control the airflow from different sections of the duct. For example, when only located on the left side, if it is in a closed state, the airflow can only flow to the right, controlling the airflow from a certain section of the air duct 2 in conjunction with the first baffle 30. When only located on the right side, if it is in a closed state, the airflow can only flow to the left, controlling the airflow from a certain section of the air duct 2 in conjunction with the first baffle 30. Simultaneously, having second baffles 40 on both sides allows for control of opening and closing as needed, controlling the direction of airflow to allow air to exit in different directions. In essence, by setting the second baffle 40, it is equivalent to controlling the airflow from only a certain section of the air duct 20.

[0053] Please see Figure 3In one embodiment of the present invention, the air duct 20 may include a horizontal section 23 and at least one curved section 22. The main air outlet 10 is located on the horizontal section 23, and at least one sub-air outlet 21 is provided on the curved section 22. By setting at least part of the air duct 20 as the curved section 22, the curved section 22 has different heights and the sub-air outlet 21 is provided on the curved section 22, air can be discharged to different heights to meet the requirements of users at different heights, or to adapt to the standing posture at a higher height or the sitting posture or lying posture at a lower height, thereby improving the practicality of the air duct 20.

[0054] Specifically, in this embodiment, the curved section 22 is parabolic in shape, and the vertex 221 of the parabola is provided with a sub-air outlet 21. The curved section 22 can be arranged opposite to or adjacent to the main air outlet 10. By setting the curved section 22 to be parabolic, it can have different heights relative to the ground, and air can be discharged at different heights. Furthermore, by arranging it opposite to the main air outlet 10, the airflow loss is reduced. The airflow first flows from the horizontal section 23 and then flows to the curved section 23, thereby reducing the loss of wind power.

[0055] When the air duct 20 includes multiple curved sections 22, and the multiple curved sections 22 are arranged continuously, it can be understood that the multiple curved sections 22 form a wave shape. A sub-outlet 21 can be set at the crest and trough of the wave shape, so that the height of the air outlet is different, which can adapt to people of different heights. It can be understood that the sub-outlet 21 at the trough is at a lower height, so it can blow towards people who are shorter or people who are sitting or lying down; the sub-outlet 21 at the crest is at a higher height, so it can blow towards people who are taller or people who are standing.

[0056] For example, when the air duct 20 in this embodiment is installed in a square room, only the air duct 20 located on one side of the wall can be set in a wavy shape, thereby reducing air loss within the air duct 20 and increasing the airflow from the sub-air outlets 21 in other locations. Understandably, when the room is square and the indoor air conditioner unit is suspended on one wall, the air duct 20 on the wall opposite the indoor air conditioner unit can be set in a wavy shape, or the air duct 20 on the wall adjacent to the indoor air conditioner unit can be set in a wavy shape, thereby reducing airflow loss from the main air outlet 10.

[0057] In addition, please see Figure 1Since the first wind deflector 30 is closed, preventing airflow from flowing backward, it can only flow out through the sub-outlet 21 located in front of the first wind deflector 30. Therefore, the airflow will be deflected at this time, and wind loss will occur when it hits the first wind deflector 30. In order to reduce wind loss, the first wind deflector 30 in this embodiment is inclined relative to the air guide duct 20 and inclined relative to the direction of the incoming airflow. Thus, when the airflow hits the first wind deflector 30, the inclined first wind deflector 30 can assist in deflection, reducing wind loss. It can be understood that when the first wind deflector 30 needs to be opened relative to the air guide duct 20, it needs to be rotated in the direction of the incoming airflow to open the flow channel behind it.

[0058] Understandably, the first wind deflector 30 can be positioned close to the sub-outlet 21, so that when the first wind deflector 30 is open, it can close one sub-outlet 21 located in the direction of the incoming airflow. This allows all the airflow to flow to the rear, increasing the airflow to the rear sub-outlet 21. Through the cooperation of all the first wind deflectors 30, airflow can be directed through only one sub-outlet 21, thus achieving directional airflow delivery. Understandably, the number of first wind deflectors 30 and sub-outlets 21 is the same, with one first wind deflector 30 at each sub-outlet 21.

[0059] Furthermore, it is understood that in order to control the amount of airflow at different locations of the air duct 20, the first baffle 30 in this embodiment can be driven by the first drive 50 to partially or fully open relative to the inner cavity of the air duct 10. Thus, when the inner cavity of the air duct 10 is partially open, the airflow can continue to flow backward, thereby controlling the amount of airflow from the rear sub-air outlet 21 and preventing the user from feeling uncomfortable when the airflow is too large.

[0060] Understandably, the first driving component 30 can be a driving component and a transmission mechanism, and the first windshield component 30 can be partially opened, fully opened or closed by a drive motor.

[0061] Please see Figures 2 to 5 In one embodiment of the present invention, the air guiding device 100 further includes a plurality of air adjusting mechanisms 60, and each sub-air outlet 21 is provided with an air adjusting mechanism 60. The air adjusting mechanism 60 is used to adjust the airflow direction at the sub-air outlet 21. Thus, by providing an air adjusting mechanism 60 at each sub-air outlet 21, the airflow direction of the sub-air outlet 21 can be adjusted, for example, to flow upward or downward, or to flow left or right, making it more convenient for users to use.

[0062] Specifically, the air regulating mechanism 60 includes multiple air regulating components 62, which are arranged separately from each other. Each air regulating component 62 includes an arc-shaped air guide surface 621 and a planar air guide surface 622. Every two air regulating components 62 form a group, and the two air regulating components 62 in each group are arranged in a mirror image. That is, when the air regulating components 62 are set, the arc-shaped air guide surface 621 of the multiple air regulating components 62 faces the arc-shaped air guide surface 621, and the planar air guide surface 622 faces the planar air guide surface 622. By setting the air regulating components 62 to include the arc-shaped air guide surface 621, the airflow can achieve the Coanda effect on the arc-shaped air guide surface 621. The airflow flows along the surface of the arc-shaped air guide surface 621. The cooperation of multiple air regulating components 62 achieves the effect of dispersing or concentrating airflow. Meanwhile, due to the arc-shaped air guide surface 621, the airflow flows along the surface of the arc-shaped air guide surface 621. At the same time, the arc-shaped air guide surface 621 can reduce the forced turning of the airflow, resulting in better airflow comfort and a gentler wind feel.

[0063] The air conditioning mechanism 60 in this embodiment also includes a second driving member 61, which is used to drive at least one air conditioning member 62 to move. By setting the second driving member 61 to drive at least one air conditioning member 62 to move, different air outlet modes can be adjusted.

[0064] Specifically, the second driving member 61 can drive the air regulating member 62 to move forward or rotate relative to the sub-air outlet 21, thereby adjusting different air outlet modes. For example, it can drive the spaced-apart air regulating members 62 to move forward respectively, so that the air regulating members 62 have an interleaved air regulating mode; or it can drive at least one of the air regulating members 62 to rotate relative to the sub-air outlet 21, thereby achieving deflection of air in different directions.

[0065] For example, please see Figure 5 When the second driving component 61 drives the two adjacent air regulating components 62 to rotate in the same direction, the downward deflection effect is achieved.

[0066] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
