Description

[0001] This application is required to be filed with the Chinese Patent Office on October 28, 2024, application number:

[0002] Priority is given to Chinese Patent Application No. 202411514814.7 entitled “Air Guide Component and Air Handling Equipment”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of air handling equipment technology, and in particular to a guide vane, an adjustment component, an air guiding component, and an air handling device. Background Technology

[0004] Air handling equipment, such as air conditioning units, typically includes an air outlet and an air deflector plate installed at the air outlet. The air deflector plate is rotatably connected to the air outlet, and the direction of airflow from the air outlet is changed by altering the angle at which the air deflector plate opens relative to the air outlet.

[0005] However, this method of adjusting the air supply direction results in a relatively limited air supply area for the air handling equipment. Utility Model Content

[0006] This application provides an air guide vane, an adjustment component, an air guide assembly, and an air handling device. The air guide vane can change the air delivery angle of the adjustment component, and the air delivery area of ​​the air guide assembly can be adjusted more flexibly, thereby expanding the air delivery coverage area of ​​the air handling device.

[0007] The first aspect of this application provides an air guide vane for installation at the air outlet of an air handling device. The air guide vane includes a vane body, which includes a first curved portion and a second curved portion. The first curved portion and the second curved portion are respectively located on both sides of the central axis of the vane body. The first curved portion and the second curved portion are respectively curved to both sides of the thickness direction of the air guide vane, and the side of the first curved portion away from the central axis is the first air guide side, and the side of the second curved portion away from the central axis is the second air guide side.

[0008] The air guide blade provided in this application has a first curved portion and a second curved portion on its blade body. The first and second curved portions are located on opposite sides of the central axis of the blade body, respectively, and are curved in opposite directions along the thickness of the air guide blade. The side of the first curved portion away from the central axis is the first air guide side of the air guide blade, and the side of the second curved portion away from the central axis is the second air guide side of the air guide blade. Since the extension lines of both the first and second air guide sides form angles with the reference plane on which the blade body is located, the air delivery angle of the adjustment component can be changed regardless of whether the first or second air guide side is on the outside during operation of the air handling equipment. This makes the adjustment of the air delivery area by the air guide component more flexible, thereby expanding the air delivery coverage area of ​​the air handling equipment.

[0009] In one possible implementation, the extension line of the first guide side has a first angle with the reference plane, and the extension line of the second guide side has a second angle with the reference plane. The reference plane is the orthographic projection of the blade body and passes through the central axis. The angle of the first angle is greater than the angle of the second angle.

[0010] In this way, when the first air guide side faces outward from the air outlet, the airflow deflects at a relatively larger angle towards the same side of the air outlet. Conversely, when the second air guide side faces outward from the air outlet, the airflow deflects at a relatively smaller angle towards the same side of the air outlet. Therefore, users can adjust the opening state of the air guide vanes according to actual needs to obtain different air delivery directions and areas. Furthermore, the different structures on both sides of the central axis of the air guide vanes facilitate identification and installation, reducing the probability of rework and scrapping of the adjustment components.

[0011] Especially when the first guide side faces outward from the air outlet and the second guide side faces inward from the air outlet, the airflow can better utilize the Coanda effect and expand the air outlet angle of the guide blades as it flows along the first bend towards the first guide side. At the same time, the second bend is closer to the inside of the air outlet and has a smaller curvature, which is more conducive to reducing airflow resistance.

[0012] In one possible implementation, the difference between the angle of the first included angle and the angle of the second included angle is in the range of 6°-12°.

[0013] In this way, there is a significant angular difference between the first included angle α and the second included angle β. When the guide vanes are at the same deflection angle, the air delivery direction and air delivery area of ​​the adjustment component are significantly different when the first guide side faces outward from the air outlet and when the second guide side faces outward from the air outlet. Furthermore, the angular difference between the first included angle α and the second included angle β will not be too large, and there are no excessively bent parts in the guide vanes, which can ensure the overall reliability and service life of the guide vanes.

[0014] In one possible implementation, when the guide vane is in the first open state, the first guide side faces outward from the air outlet and the second guide side faces inward from the air outlet; when the guide vane is in the second open state, the first guide side faces inward from the air outlet and the second guide side faces outward from the air outlet.

[0015] In this way, the air guide vanes can increase the airflow deflection angle using both the first and second air guide sides. There are no restrictions on the rotation angle of the air guide vanes, making their control more flexible and the operation simpler.

[0016] In one possible implementation, when the guide vane is perpendicular to the plane of the air outlet and the first guide side faces outward from the air outlet, the extension line of the first guide side extends to the same side of the air outlet; and / or, when the guide vane is perpendicular to the plane of the air outlet and the second guide side faces outward from the air outlet, the extension line of the second guide side extends to the same side of the air outlet.

[0017] Thus, when the first air guide side faces outward from the air outlet, the air delivery deflection angle of the air guide blades can be further increased when the air guide blades are directed to the same side of the air outlet. When the second air guide side faces outward from the air outlet, the air delivery deflection angle of the air guide blades can also be further increased when the air guide blades are directed to the same side of the air outlet. This, in turn, expands the air delivery area of ​​the regulating component.

[0018] In one possible implementation, the angle between the extension line of the first air guide side and the reference plane ranges from 5° to 55°, and the angle between the extension line of the second air guide side and the reference plane ranges from 5° to 45°.

[0019] In this way, the guide vanes only need to rotate within a small angle range to achieve a large air delivery area. Furthermore, the angle between the extension line of the first (or second) guide side and the reference plane is not excessive, the curvature of the first (or second) bend is appropriate, and the guide vanes do not obstruct airflow. The overall wind resistance of the adjustment assembly is very low, and it does not affect the air delivery volume of the air handling unit.

[0020] In one possible implementation, the angle between the extension line of the first air guide side and the reference plane ranges from 25° to 55°, and the angle between the extension line of the second air guide side and the reference plane ranges from 25° to 45°.

[0021] In this way, the first air guide side (or the second air guide side) can significantly increase the air delivery deflection angle of the air guide blades, which can better expand the air delivery area of ​​the adjustment component.

[0022] In one possible implementation, both the first and second curved portions are smooth curved portions, and both the first and second curved portions have only one curved vertex.

[0023] In this way, the overall curvature of the first (or second) bend is relatively gentle, allowing airflow to flow smoothly along its surface. While changing the direction of airflow, it does not obstruct the airflow. Furthermore, the first (or second) bend only once towards one side of the blade body's thickness, avoiding the formation of a wavy surface. This prevents the first (or second) bend from repeatedly changing the airflow direction, thus avoiding any impact on the air delivery direction of the guide vanes and ensuring the effective adjustment of the air delivery deflection angle of the guide vanes by the first (or second) bend.

[0024] In one possible implementation, the extension line of the first air guide side extends toward a first side of the reference plane, and the bending vertex of the first bend is located on a second side of the reference plane; and / or, the extension line of the second air guide side extends toward a second side of the reference plane, and the bending vertex of the second bend is located on a first side of the reference plane.

[0025] This design avoids the extension line of the first (or second) guide side and the bend apex of the first (or second) bend being located on the same side of the reference plane, thus preventing excessive skewing of the first (or second) bend towards the guide blade. The guide blade is generally flat with a small degree of curvature, resulting in lower wind resistance. During long-term use, the guide blade exhibits higher reliability and a longer service life.

[0026] In one possible implementation, the blade body further includes a straight portion, the two ends of which are connected to a first curved portion and a second curved portion, respectively.

[0027] In this way, the blade body can guide air through the first and second curved sections on both sides, thereby expanding the air delivery coverage of the guide vanes. Simultaneously, the smoothness of the straight section in the middle of the blade body is better, which reduces wind resistance within the air guide channel and increases the gas velocity exiting the outlet. Furthermore, the straight section has a better effect on dispersing air pressure, resulting in more uniform stress on the blade body and improving its reliability and service life.

[0028] In one possible implementation, the first end of the straight portion extends along the tangent direction of the first curved portion, and the second end of the straight portion extends along the tangent direction of the second curved portion; wherein the first end of the straight portion is connected to the first curved portion, and the second end of the straight portion is connected to the second curved portion.

[0029] In one possible implementation, a number of air outlet holes are distributed on the blade body, and the air outlet holes penetrate both sides of the blade body in the thickness direction.

[0030] In this way, part of the airflow blown out of the duct will flow outward along the air guide channel formed between adjacent guide vanes, while another part can flow outward through the air outlet on the vane body. The interaction of these two airflows can prevent strong winds from being blown out of the air outlet, making the air delivery effect of the air handling equipment gentler and improving the user comfort of the air handling equipment.

[0031] In one possible implementation, the air outlet extends obliquely toward the first air guide side from the first surface of the blade body to the second surface of the blade body; wherein the first surface and the second surface are the two sides of the blade body in the thickness direction, and the extension line of the first air guide side extends toward the side where the first surface is located.

[0032] Thus, when the guide vanes are in the open state, the angle between the extension direction of the air outlet and the side of the blade body near the air outlet in the air supply direction of the regulating component is an acute angle, and the air outlet direction tends to be in the guiding direction of the blade body. The airflow blowing out of the air outlet has little impact on the overall air supply direction of the regulating component, which can ensure the adjustment accuracy of the regulating component in terms of air supply direction and air supply area.

[0033] In one possible implementation, the angle between the extension direction of the air outlet and the reference plane ranges from 30° to 60°.

[0034] By designing the angle between the extension direction of the air outlet and the reference plane to be less than or equal to 60°, when the adjustment component directs airflow to the same side of the air outlet, the airflow from the air outlet will not be significantly directed to the other side of the air outlet, resulting in a better overall adjustment effect of the adjustment component. Furthermore, the smaller the angle between the extension direction of the air outlet and the reference plane, the closer the air outlet's airflow direction is to the overall airflow direction of the adjustment component.

[0035] In one possible implementation, the guide vane further includes a rotating shaft connected to the vane body, and the rotating shaft extends along the central axis of the vane body, with the vane body rotating about the rotating shaft.

[0036] In this way, the guide vanes can be rotatably connected to the support plate using a rotating shaft. By rotating the vane body around the rotating shaft, the airflow direction of the adjustment component can be changed. Furthermore, by setting the rotating shaft on the central axis of the vane body, the guide vanes have better stability and higher reliability, which also facilitates the layout design of the guide vanes and minimizes the required space for their movement.

[0037] In one possible implementation, the air guide vanes can move between the inside and outside of the air outlet.

[0038] This changes the position of the guide vanes relative to the air outlet, significantly reducing interference between the guide vanes and the air duct. The deflection angle of the guide vanes is less affected by the air duct, allowing for a wider deflection angle range and expanding the air delivery coverage area of ​​the air handling unit.

[0039] The second aspect of this application provides an adjustment assembly installed at the air outlet of an air handling device. The adjustment assembly includes: a support plate extending along the length of the air outlet; a plurality of guide vanes, each guide vane being movably connected to the support plate, and each guide vane being arranged sequentially along the surface of the support plate; wherein at least some of the guide vanes are the guide vanes as described above.

[0040] The adjustment component provided in this application adjusts the air delivery angle of the adjustment component by sequentially arranging each air guide blade on the surface of the support plate and movably connecting each air guide blade to the support plate, thereby changing the angle between each air guide blade and a certain direction on the surface of the support plate.

[0041] The adjustment component, since it includes the aforementioned air guide vanes, possesses all the technical effects of air guide vanes, which will not be elaborated here.

[0042] In one possible implementation, the guide vanes are arranged sequentially along the length of the support plate.

[0043] In one possible implementation, when the first air guide side of each air guide blade faces outward from the air outlet, the angle between the extension line of the first air guide side of each air guide blade and the reference plane gradually increases along the direction near the end of the air outlet; and / or, when the second air guide side of each air guide blade faces outward from the air outlet, the angle between the extension line of the second air guide side of each air guide blade and the reference plane gradually increases along the direction near the end of the air outlet.

[0044] In this way, from the center to the end of the air outlet, the airflow deflection angle of the regulating component gradually increases, resulting in a larger airflow area and a wider airflow coverage. Furthermore, the airflow area gradually expands outward, making the airflow more dispersed and the airflow gentler.

[0045] A third aspect of this application provides an air guide assembly installed at the air outlet of an air handling device. The air guide assembly includes: an adjustment assembly as described above; and a first drive assembly connected to the adjustment assembly and driving the air guide blades in the adjustment assembly to change position relative to the support plate.

[0046] The air guide assembly provided in this application drives the movement of each air guide blade by setting a first driving component, so as to change the angle between each air guide blade and a certain direction on the surface of the support plate, thereby adjusting the air delivery angle of the adjustment component.

[0047] The air guide assembly, which includes the aforementioned air guide blades, possesses all the technical effects of air guide blades, which will not be elaborated here.

[0048] In one possible implementation, the first drive component also drives the movement of the carrier plate in the adjustment component.

[0049] In this way, the first drive component both drives the movement of the individual guide vanes on the support plate and drives the guide vanes together with the support plate to move. This allows for flexible adjustment of the air delivery angle of the air delivery component, expanding its air delivery area and achieving a larger air delivery coverage area. It also enables faster adjustment of indoor temperature, improves indoor temperature uniformity, and enhances indoor comfort.

[0050] Furthermore, by using the first drive component to drive both the air guide vanes and the support plate, the driving method of the air guide component is simplified, which can reduce the number of drive components and the space occupied, and help reduce the energy consumption of the air guide component.

[0051] In one possible implementation, there are two regulating components, which are spaced apart along the length of the air outlet.

[0052] In this way, the two regulating components can deliver air to different areas separately, expanding the air delivery area of ​​the air guide components and increasing the air handling unit's coverage area. This, in turn, allows for more uniform temperature regulation throughout the room, reducing temperature differences and minimizing discomfort from strong drafts in localized areas, thus improving overall indoor comfort. Furthermore, the air handling unit can achieve its cooling or heating targets in a shorter time, resulting in higher energy efficiency.

[0053] In one possible implementation, the air guide assembly further includes at least one second drive assembly connected between two adjacent adjustment assemblies, and the second drive assembly simultaneously drives the carrier plates in the two adjustment assemblies to move.

[0054] By setting a first drive component to drive the air guide vanes and a second drive component to drive the support plate, each drive a single moving object, the driving method is relatively simple. The structural design of both the first and second drive components can also be simplified, reducing design costs. Furthermore, the first and second drive components do not interfere with each other, resulting in higher operational reliability of the air guide assembly.

[0055] A fourth aspect of this application provides an air handling device, including a device body and an air guide assembly as described above.

[0056] The air handling equipment provided in this application, since it includes the aforementioned air guiding component, possesses all the technical effects of the air guiding component, which will not be elaborated here. Attached Figure Description

[0081] As described in the background section, traditional air conditioning equipment uses swingable air guide vanes within the duct to adjust the airflow angle. For example, horizontally positioned air guide vanes swing up and down to achieve vertical airflow, while vertically positioned air guide vanes swing left and right to achieve horizontal airflow. The swing angle of all air guide vanes is uniformly controlled by linkages, thereby adjusting the overall airflow area of ​​the air conditioning equipment.

[0082] However, the aforementioned method of adjusting the air supply area results in a positive correlation between the size of the air supply area and the size of the air outlet. This leads to a relatively limited air supply area for the air conditioning equipment, with a small air supply coverage area, making it impossible to supply air to large areas.

[0083] In view of this, embodiments of this application provide an air guide vane, an adjustment component, an air guide assembly, and an air handling device. The air guide assembly is installed at the air outlet of the air handling device. The air guide assembly includes at least one adjustment component, and each adjustment component is provided with multiple air guide vanes. The air supply area of ​​the air handling device is adjusted by the swinging of the air guide vanes.

[0084] By designing at least some of the guide vanes, a first curved portion and a second curved portion are provided on the blade body. The first and second curved portions are located on opposite sides of the central axis of the blade body, respectively, and are curved to opposite sides in the thickness direction of the guide vane. The side of the first curved portion away from the central axis is the first guide side of the guide vane, and the side of the second curved portion away from the central axis is the second guide side of the guide vane. Since the extension lines of both the first and second guide sides form angles with the reference plane where the blade body is located, when the air handling unit is working, regardless of whether the first or second guide side is on the outside, the air delivery angle of the adjustment component can be changed, making the adjustment of the air delivery area by the guide component more flexible, thereby expanding the air delivery coverage area of ​​the air handling unit.

[0085] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0086] This application provides an air handling device, which includes, but is not limited to, air conditioning equipment, humidifiers, dehumidifiers, ventilation equipment, heat recovery ventilation systems, air purifiers, and fresh air systems. In this application embodiment, an air conditioning unit is used as an example for description. The air conditioning unit may include wall-mounted air conditioners, floor-standing air conditioners, central air conditioners, split-type air conditioners, portable air conditioners, window units, ducted air conditioners, etc.

[0087] The following explanation uses a wall-mounted air conditioner as an example of an air handling unit.

[0088] Figure 1 This is a schematic diagram of an air handling device provided in an embodiment of this application. (Refer to...) Figure 1As shown, the air handling unit 1 includes a unit body 10, which has an air outlet 11 through which the air handling unit 1 supplies air to the outside. Taking a wall-mounted air conditioner as an example, the air handling unit 1 is installed on an indoor wall, and the air outlet 11 can be located on the front (the side facing away from the wall) of the unit body 10 and near the lower part. For example, the air outlet 11 can be tilted downwards, making the air supply area of ​​the air handling unit 1 more suitable.

[0089] An air guide assembly 20 is provided at the air outlet 11 of the equipment body 10. The air guide assembly 20 is used to adjust the air delivery direction and air delivery area of ​​the air handling equipment 1 so as to achieve flexible air delivery of the air handling equipment 1.

[0090] Figure 2 This is a three-dimensional structural diagram of an air guide assembly provided in an embodiment of this application.

[0091] Figure 3 for Figure 2 A three-dimensional structural diagram of the air guide component from another perspective.

[0092] Reference Figure 2 As shown, the air guiding assembly 20 includes an adjustment assembly 100, which is disposed within the air duct of the device body 10. The air duct has a mounting base for the adjustment assembly 100, on which the adjustment assembly 100 can be installed. Furthermore, the adjustment assembly 100 can be located at the air outlet 11 of the device body 10. For example, the adjustment assembly 100 can cover most of the area of ​​the air outlet 11, so as to adjust the airflow direction and airflow area of ​​the device body 10.

[0093] For ease of explanation, this embodiment defines the basic air duct wall 12 (see...). Figure 1 As shown, the basic air duct wall 12 is, for example, the side wall of the air duct closest to the wall, and the adjustment component 100 can be installed on the basic air duct wall 12. The adjustment component 100 can be directly installed on the basic air duct wall 12, or it can be installed on the basic air duct wall 12 through other support components.

[0094] The adjustment assembly 100 may include a support plate 110 and a plurality of guide vanes 120. The support plate 110 may be mounted on the base duct wall 12, and the surface of the support plate 110 may be parallel to the surface of the base duct wall 12, for example. Furthermore, the support plate 110 may extend along the length of the air outlet 11 so that the adjustment assembly 100 can cover the air outlet 11. Each guide vane 120 is sequentially arranged along the surface of the support plate 110, and each guide vane 120 is movably connected to the support plate 110.

[0095] The support plate 110 is located close to the base duct wall 12 to facilitate the installation of the adjustment assembly 100 onto the base duct wall 12. The guide vane 120 can be located on the side of the support plate 110 facing away from the base duct wall 12, with the guide vane 120 facing the air outlet 11 and extending towards the air outlet 11. In this way, the airflow within the duct can pass through the guide vane 120 before being blown out from the air outlet 11, thus guiding the airflow through the guide vane 120.

[0096] Reference Figure 3 As shown, the air guide assembly 20 also includes a drive mechanism 200, which is connected to the adjustment assembly 100. The drive mechanism 200 drives the adjustment assembly 100 to move, thereby adjusting the air delivery direction and air delivery area.

[0097] The drive mechanism 200 is used to drive the movement of each guide vane 120 of the adjustment assembly 100, causing the position of each guide vane 120 relative to the support plate 110 to change. The angle between each guide vane 120 and a certain direction on the surface of the support plate 110 changes, and each guide vane 120 deflects uniformly toward one side of the air outlet 11 to adjust the air delivery angle of the adjustment assembly 100.

[0098] Based on this, the support plate 110 can be movably connected to the basic air duct wall 12, and the drive mechanism 200 can also be used to drive the support plate to move. By driving the support plate 110 to move through the drive mechanism 200, the position of the support plate 110 relative to the air outlet 11 changes, and the distance between the support plate 110 and the basic air duct wall 12 changes.

[0099] The guide vanes 120 on the support plate 110 move together with the support plate 110, which can change the position of the guide vanes 120 relative to the air outlet 11. The support plate 110 can move outward toward the air outlet 11, and some or even all of the guide vanes 120 on the support plate 110 can extend beyond the air outlet 11. In this way, the interference between the guide vanes 120 and the air duct is significantly improved, and the limitation of the air duct on the deflection angle of the guide vanes 120 can be weakened or even eliminated, and the deflection angle range of the guide vanes 120 can be further expanded.

[0100] With this configuration, the drive mechanism 200 both drives the individual air guide vanes 120 on the support plate 110 and drives the air guide vanes 120 together with the support plate 110, making the drive mechanism 200's driving method for the adjustment component 100 more flexible. This allows for flexible adjustment of the air delivery angle of the air guide component 20, expanding its air delivery area and achieving a larger air delivery coverage area. It also enables faster adjustment of indoor temperature, improves indoor temperature uniformity, and enhances indoor comfort.

[0101] Furthermore, the air guide assembly 20 can direct airflow towards a wider area, improving the accuracy of its airflow adjustment. Moreover, by adjusting the airflow angle of the air guide assembly 20 through the drive mechanism 200, the airflow area can be directed away from the user's activity area, preventing discomfort or health problems caused by direct cold air blowing on the user. The drive mechanism 200 can also continuously change the airflow angle of the air guide assembly 20, preventing it from blowing directly onto a single area for extended periods and improving the uniformity of the overall indoor temperature.

[0102] In this embodiment, the drive mechanism 200 drives the support plate 110 to move in a swinging motion. The support plate 110 can swing (or rotate) around its own rotation axis on the basic air duct wall 12. This changes the position of the support plate 110 relative to the air outlet 11, altering the angle between the support plate 110 and the plane of the air outlet 11. Taking a certain end of the support plate 110 away from its own rotation axis as a reference, that end of the support plate 110 swings towards the air outlet 11 (e.g., that end of the support plate 110 extends beyond the air outlet 11), or it swings away from the air outlet 11 (e.g., that end of the support plate 110 retracts into the air outlet 11).

[0103] In this way, the drive mechanism 200 not only drives the guide vane 120 to swing relative to the support plate 110, changing the angle between the guide vane 120 and the support plate 110 in a certain direction, but also adjusts the air delivery direction by swinging the guide vane 120 itself. Furthermore, the drive mechanism 200 also drives the support plate 110 to swing relative to the air outlet 11, superimposing the deflection angle of the support plate 110 on top of the deflection angle of the guide vane 120, thus achieving adjustment of the air delivery direction. This increases the air delivery angle range of the adjustment component 100, expands the air delivery area of ​​the adjustment component 100, and results in a larger air delivery coverage area for the air handling equipment 1.

[0104] Of course, in other embodiments, the movement of the drive mechanism 200 driving the support plate 110 can also be translational. The length direction of the support plate 110 is always consistent with the length direction of the air outlet 11, and the support plate 110 translates along its width direction on the basic air duct wall 12. This changes the position of the support plate 110 relative to the air outlet 11. For example, the support plate 110 moves from a position housed within the air duct toward the air outlet 11; for example, the support plate 110 moves to the plane where the air outlet 11 is located, or even the entire support plate 110 extends outside the air outlet 11. Alternatively, the support plate 110 moves from a position located on the plane of the air outlet 11 or outside the air outlet 11 toward the air duct, so that the support plate 110 is retracted into the air duct.

[0105] In this way, the drive mechanism 200 can drive the support plate 110 to move towards the air outlet 11, making the guide vanes 120 on the support plate 110 closer to the air outlet 11, or even extend beyond the air outlet 11. This avoids the air duct restricting the swing range of the guide vanes 120 and increases the deflection angle range of the guide vanes 120. Furthermore, this expands the air delivery area of ​​the adjustment assembly 100 and the air delivery coverage area of ​​the air handling unit 1. When the deflection angle of the guide vanes 120 is too large, and the air delivery area of ​​the air guide assembly 20 faces the edge of the air outlet 11, it also avoids the air duct obstructing the air delivery of the air guide assembly 20 and prevents turbulent airflow.

[0106] The following explanation will take the example of the drive mechanism 200 driving the bearing plate 110 to swing on the foundation air duct wall 12.

[0107] Reference Figure 2 or Figure 3 Regarding the air guiding method of the air guiding assembly 20, as one implementation method, the air guiding assembly 20 can be used to achieve left and right sweeping. In this case, the air guiding blades 120 installed on the support plate 110 can be arranged sequentially at intervals along the length direction of the support plate 110. Through the air guiding channel formed between two adjacent air guiding blades 120, the airflow blown out of the duct is guided. Each air guiding blade 120 can swing towards both ends of the length direction of the air outlet 11, or in other words, each air guiding blade 120 swings towards the left and right ends of the air outlet 11, thereby guiding the airflow to the left or right side of the air outlet 11.

[0108] For example, each guide vane 120 can be rotatably connected to the support plate 110. The rotation axis of each guide vane 120 can be perpendicular to the surface of the support plate 110, and the blade surface of each guide vane 120 can also be perpendicular to the surface of the support plate 110. The drive mechanism 200 can drive each guide vane 120 to rotate along its own rotation axis, so that all guide vanes 120 can swing uniformly towards the left and right ends of the air outlet 11.

[0109] In other embodiments, the air guide assembly 20 can also be used to achieve vertical air sweeping. In this case, the air guide blades 120 installed on the support plate 110 can be arranged sequentially at intervals along the width direction of the support plate 110, and the airflow blown out of the air duct is guided through the air guide channel formed between two adjacent air guide blades 120. Each air guide blade 120 can swing to both ends in the height direction (or width direction) of the air outlet 11, or in other words, each air guide blade 120 swings to both the upper and lower ends of the air outlet 11, so as to guide the airflow to the top or bottom of the air outlet 11.

[0110] For example, each guide vane 120 can also be rotatably connected to the support plate 110. The rotation axis of each guide vane 120 can be parallel to the surface of the support plate 110, and the guide vane 120 can be connected to the support plate 110 via a support member. For instance, the two ends of the extending direction of the guide vane 120 are its rotation axes, and the rotation axes at both ends of the guide vane 120 are rotatably connected to the support plate 110 via a support member, with a gap between the guide vane 120 and the surface of the support plate 110. The drive mechanism 200 can drive each guide vane 120 to rotate along its own rotation axis, so that all guide vanes 120 swing uniformly towards the upper and lower ends of the air outlet 11.

[0111] In other embodiments, the air guide assembly 20 can also be used to achieve air sweeping in different directions. For example, the air guide assembly 20 can achieve both left-right sweeping and up-down sweeping. That is, each air guide blade 120 can swing towards both ends (left and right ends) in the length direction of the air outlet 11, and each air guide blade 120 can also swing towards both ends (up and down ends) in the height direction of the air outlet 11.

[0112] For example, each guide vane 120 can also be rotatably connected to the support plate 110. Since the air guide assembly 20 can achieve air sweeping in different directions, each guide vane 120 can have a rotation axis with different directions. For example, each guide vane 120 has a rotation axis perpendicular to the surface of the support plate 110, and each guide vane 120 has a rotation axis parallel to the surface of the support plate 110. All guide vanes 120 are mounted on the support plate 110, for example, in the form of an air guide assembly. Each air guide assembly includes multiple guide vanes 120, and each air guide assembly is rotatably connected to the support plate 110 via a rotation axis perpendicular to the surface of the support plate 110. Each guide vane 120 in each air guide assembly is provided with a rotation axis parallel to the surface of the support plate 110.

[0113] The following description uses the air guide assembly 20 to achieve left and right air sweeping as an example. Each air guide blade 120 is arranged sequentially along the length of the support plate 110. Each air guide blade 120 is rotatably connected to the support plate 110, and the rotation axis of each air guide blade 120 is perpendicular to the plate surface of the support plate 110.

[0114] Continue to refer to Figure 2 or Figure 3 Regarding the design of the number of adjustment components 100 in the air guide assembly 20, as one implementation, there can be two adjustment components 100, which can be spaced apart along the length of the air outlet 11. Under the drive of the drive mechanism 200, the air guide blades 120 of both adjustment components 100 can deflect relative to their respective support plates 110, and the support plates 110 of both adjustment components 100 can also deflect relative to the air outlet 11.

[0115] By arranging two regulating components 100 at intervals along the length of the air outlet 11, the two regulating components 100 can respectively deliver air to different areas. The two regulating components 100 have different air delivery areas, which can expand the air delivery area of ​​the air guide component 20 and expand the air delivery coverage area of ​​the air handling equipment 1.

[0116] Taking the paper orientation in the diagram as an example, the adjustment component 100 on the left is driven by the drive mechanism 200, causing its guide vanes 120 to deflect to the left. Similarly, the adjustment component 100 on the right is driven by the drive mechanism 200, causing its guide vanes 120 to deflect to the right. This expands the overall air delivery area of ​​the air guide component 20. Furthermore, if the drive mechanism 200 drives the support plate 110 in the left adjustment component 100 to deflect to the left and the support plate 110 in the right adjustment component 100 to deflect to the right, the overall air delivery area of ​​the air guide component 20 will be further expanded.

[0117] This configuration allows the air conditioner to have a larger airflow coverage area, enabling more even temperature regulation throughout the room, reducing temperature differences and improving overall comfort. Furthermore, the larger airflow coverage area allows the air conditioner to reach the set temperature more quickly, achieving cooling or heating goals in a shorter time, resulting in higher energy efficiency. Additionally, the larger airflow coverage area distributes the airflow more widely and at a gentler speed, reducing discomfort from strong drafts in certain areas and providing a softer, more natural and comfortable experience for users in the air-conditioned environment.

[0118] As another implementation, the air guide assembly 20 may also include only one adjustment assembly 100. Driven by the drive mechanism 200, the air guide vanes 120 of the adjustment assembly 100 can deflect relative to the support plate 110, which in turn can deflect relative to the air outlet 11. Therefore, one adjustment assembly 100 also has a sufficiently large air supply area to meet the needs of typical indoor spaces.

[0119] For example, when the air handling unit 1 is used in a residential space, where the indoor space is small, a single regulating component 100 can meet the indoor space requirements. Alternatively, when the deflection angle range of the guide vanes 120 of the regulating component 100 is large, and the deflection angle range of the support plate 110 is also large, and the superposition of the guide vanes 120 and the support plate 110 gives the regulating component 100 a large air supply area, a single regulating component 100 can also meet the air supply requirements of a large space. In this case, the air guide assembly 20 can be equipped with only one regulating component 100.

[0120] Of course, in other embodiments, the air guide assembly 20 may also include three or more adjustment assemblies 100, each of which is arranged sequentially along the length of the air outlet 11. The drive mechanism 200 drives the air guide blades 120 of each adjustment assembly 100 to deflect relative to their respective support plates 110, and the drive mechanism 200 also drives the support plates 110 of each adjustment assembly 100 to deflect relative to the air outlet 11.

[0121] For example, when the air handling unit 1 is large in size and has a long air outlet 11, multiple adjusting components 100 can be arranged sequentially at intervals along the length of the air outlet 11, with each adjusting component 100 maintaining a suitable length to meet the stability and reliability requirements of the adjusting component 100. Alternatively, when the air handling unit 1 is used in large spaces such as offices or factories, multiple adjusting components 100 can be arranged to give the air guiding component 20 a larger air supply coverage area to meet the air supply needs of large spaces.

[0122] Reference Figure 3 As shown, in order to enable the drive mechanism 200 to both drive the guide vanes in the adjustment assembly to deflect relative to the support plate and drive the support plate to deflect relative to the air outlet, the drive mechanism 200 may include a first drive assembly 210, which is connected to the adjustment assembly. The first drive assembly 210 is at least used to drive the guide vanes in the adjustment assembly to deflect relative to the support plate.

[0123] The first drive component 210 and the adjustment component can be configured in a one-to-one correspondence. When the air guide component includes two or more adjustment components, the drive mechanism 200 can also include two or more first drive components 210, with each first drive component 210 correspondingly connected to each adjustment component. This allows the first drive component 210 to drive the corresponding adjustment component to move.

[0124] Reference Figure 3As shown, in some embodiments, when the air guide assembly includes two or more adjustment components, the drive mechanism 200 may further include at least one second drive component 220, which may be connected between two adjacent adjustment components. In this case, the first drive component 210 may only be used to drive each air guide blade to deflect relative to the support plate, and the second drive component 220 drives the support plate in the two adjustment components connected on both sides of it to move.

[0125] When the air guide assembly includes two adjustment components, the drive mechanism 200 may be provided with only one second drive component 220. The second drive component 220 is connected between the two adjustment components and can drive the support plates of the two adjustment components to move relative to each other.

[0126] When the air guide assembly includes three or more adjusting components, a second drive component 220 can be provided between each pair of adjacent adjusting components. The second drive component 220 drives the support plates of the adjacent adjusting components to move relative to each other. Alternatively, only one second drive component 220 can be provided between each pair of adjacent adjusting components, and the other adjacent adjusting components are connected by a transmission structure. The driving force of the second drive component 220 is transmitted through the transmission structure, so that the support plates of all adjusting components can move.

[0127] By setting the first drive assembly 210 to drive the air guide vanes and the second drive assembly 220 to drive the support plate, each drive assembly 210 and 220 drives a moving object, resulting in a relatively simple driving method and simplified structural design. This also reduces the design difficulty and cost of the first and second drive assemblies. Furthermore, the first and second drive assemblies do not interfere with each other; even if one fails, it does not affect the other. The probability of both the air guide vanes and the support plate failing to move is low, resulting in higher operational reliability of the air guide assembly.

[0128] In other embodiments, the drive mechanism 200 may include only the first drive component 210, which drives the deflection of each guide vane of the adjustment component relative to the support plate, and also drives the support plate to deflect relative to the air outlet. In this case, regardless of how many adjustment components the guide component includes, only one first drive component 210 needs to be provided for each adjustment component.

[0129] When the air guiding assembly includes two or more adjusting components, each adjusting component is independently driven by the first drive component 210. There is no linkage between the adjusting components, and the air delivery area of ​​each component can be adjusted independently. This allows the air handling unit to be adapted to different indoor layouts and usage requirements. Users can flexibly adjust the air delivery area of ​​the two adjusting components according to actual conditions to meet the needs of different environments for different air delivery areas, ensuring that the airflow blown by the air handling unit is fully and effectively utilized and avoiding waste.

[0130] Regarding the architecture design of the first drive component 210, refer to Figure 3 As shown, when the first drive assembly 210 only drives the movement of each guide vane on the support plate, the first drive assembly 210 may include only one drive motor 201. The output shaft of the drive motor 201 can directly transmit power to the guide vanes, or the output shaft of the drive motor 201 can be reduced in speed and increased in torque by a reduction gear before transmitting power to the guide vanes.

[0131] When the first drive assembly 210 simultaneously drives the guide vanes and the support plate, in one implementation, the first drive assembly 210 can be equipped with two drive motors 201, one drive motor 201 driving the guide vanes and the other drive motor 201 driving the support plate. In this way, the two drive motors 201 do not affect each other, and even if one of them fails to work, it will not affect the operation of the other. The probability of both the guide vanes and the support plate failing to move is low, and the operational reliability of the adjustment assembly is higher.

[0132] In another implementation, when the first drive assembly 210 simultaneously drives both the guide vanes and the support plate, the first drive assembly 210 may also consist of only one drive motor 201. The output shaft of this drive motor 201 can directly transmit power to the guide vanes, and the output shaft of the drive motor 201 is transmitted to the support plate via a transmission structure, so that one drive motor 201 can simultaneously drive the movement of both the guide vanes and the support plate. For example, the transmission structure can be a gear set, where the drive motor 201 directly drives the guide vanes to rotate, and the drive motor 201 drives the support plate to swing via the gear set.

[0133] Regarding the architecture design of the second drive component 220, combined with Figure 2 and Figure 3 As shown, the second drive assembly 220 may include a drive motor 201 and a transmission component 221. The drive motor 201 is connected to the transmission component 221, which is connected between the support plates of two adjacent adjustment assemblies. The drive motor 201 drives the transmission component 221 to move, and the transmission component 221 drives the two support plates to move relative to each other.

[0134] For example, the transmission component 221 may include a push-pull rod 2211 and two connecting rods 2212. The drive motor 201 is connected to the push-pull rod 2211. One end of each of the two connecting rods 2212 is connected to the push-pull rod 2211, and the other end of each connecting rod 2212 is connected to one of the two support plates. The drive motor 201 drives the push-pull rod 2211 to move in the plane of the support plate, causing the push-pull rod 2211 to drive the two connecting rods 2212 to move relative to each other, thereby causing the two support plates to swing relative to each other.

[0135] Figure 4 This is an exploded structural diagram of an adjustment component provided in an embodiment of this application. (Refer to...) Figure 4 As shown, in order to enable the first drive assembly 210 to drive all the guide vanes on the support plate to swing, the adjustment assembly can also be equipped with a linkage 130, and all the guide vanes are connected to the linkage 130. When the first drive assembly 210 is running, it can drive the linkage 130 to move, so that all the guide vanes can swing synchronously through the linkage 130.

[0136] The first drive assembly 210 can be connected to one of the guide vanes on the support plate, for example, the first drive assembly 210 can be connected to the guide vane located at one end of the support plate along its length. The first drive assembly 210 drives the guide vane to rotate, and the guide vane drives the linkage 130 connected to it to move. In turn, the linkage 130 drives all the guide vanes to swing synchronously.

[0137] Alternatively, the first drive assembly 210 can also be connected to the linkage 130. For example, the first drive assembly 210 can be connected to the linkage 130 at the position between the two guide vanes. The first drive assembly 210 drives the linkage 130 to move, and the linkage 130 causes all the guide vanes to swing synchronously.

[0138] Continue to refer to Figure 4 The linkage 130 can be housed within the support plate. This facilitates the connection of the linkage 130 with all the air guide vanes. Furthermore, the linkage 130 is concealed within the support plate, resulting in a cleaner appearance for the adjustment assembly. Additionally, the linkage 130 does not occupy any additional space and does not affect the size of the adjustment assembly, contributing to its slim profile.

[0139] To accommodate the linkage 130 within the support plate 110 and facilitate its connection with the guide vanes, the support plate 110 can be divided into a front panel 111 and a base plate 112. The front panel 111 and base plate 112 together form a receiving cavity, within which the linkage 130 is disposed. All guide vanes can be mounted on the front panel 111, and the first drive assembly 210 can be mounted on the base plate 112, passing through the base plate 112 to connect with the guide vanes or the linkage 130.

[0140] like Figure 4 As shown, as an example, the linkage 130 can be a connecting rod 130a, which extends along the extension direction of the support plate 110 and is connected to all the guide vanes 120. The drive motor 201 of the first drive assembly 210 can drive one of the guide vanes 120 to rotate, and the guide vane 120 drives the connecting rod 130a to reciprocate with a small swing amplitude. Through the swing and reciprocating motion of the connecting rod 130a, all the guide vanes 120 are driven to swing. Alternatively, the output shaft of the drive motor 201 is connected to the connecting rod 130a, and the drive motor 201 rotates to drive the connecting rod 130a to reciprocate with a small swing amplitude, thereby driving all the guide vanes 120 to swing.

[0141] By setting the linkage 130 as a connecting rod 130a, the structure of the linkage 130 can be simplified. The linkage 130 has a simple processing technology and low production cost, making it suitable for mass production and application. Furthermore, the connecting rod 130a is a simple and reliable transmission structure that can effectively convert the rotational motion of the drive motor 201 into the linear reciprocating oscillation of the connecting rod 130a itself, helping to improve the reliability and durability of the adjustment assembly 100. In addition, the geometric characteristics of the connecting rod 130a determine that it can provide precise motion control, enabling the guide vanes 120 to make precise angle adjustments within a set range, thus providing users with more precise airflow control.

[0142] As another example, the linkage can be a rack (not shown in the figure), which can extend along the extension direction of the support plate 110. Each guide vane 120 includes a gear (not shown in the figure), which can be positioned, for example, on the central axis of the guide vane 120. The output shaft of the drive motor 201 in the first drive assembly 210 can also be connected to a gear (e.g., the output shaft of the drive motor 201 is connected to a gear on one of the guide vanes 120). The drive motor 201 drives the rack to move along the extension direction of the support plate 110 via the gear, and the movement of the rack drives the gears on each guide vane 120 to rotate, thereby driving all the guide vanes 120 to rotate.

[0143] Compared to connecting rod 130a, the transmission via rack and pinion gears allows for a more flexible rotation angle. Since the gear's rotation is not limited by its length and continuous movement, it can drive the gear to rotate 360°. This allows the gear to drive the guide vanes 120 to rotate within a 0°–360° range, enabling omnidirectional airflow. Furthermore, the rack's linear motion simplifies the transmission, provides a more precise trajectory, and increases the reliability of the guide vanes 120, allowing for more accurate control of their rotation angle.

[0144] Figure 5 This is another exploded structural diagram of the adjustment component provided in an embodiment of this application. (Refer to...) Figure 5 As shown, the guide vane 120 includes a blade body 121, which is the main structure of the guide vane 120. An airflow channel is formed between the blade bodies 121 of adjacent guide vanes 120 to guide the airflow blown out of the outlet 11. The guide vane 120 is driven to move by the first drive assembly 210, changing the orientation of the blade body 121 of the guide vane 120, thereby changing the airflow direction of the adjustment assembly 100.

[0145] The thickness of the blade body 121 can be between 2mm and 3mm. This thickness satisfies the requirements for the machinability of the blade body 121 while ensuring the necessary structural strength. Simultaneously, the relatively small thickness of the blade body 121 results in a smaller space occupied by it, and sufficient spacing between adjacent blades allows for smooth airflow within the duct, preventing any impact on the air outlet of the air handling unit 1.

[0146] For example, the thickness of the blade body 121 can be 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3.0mm, etc.

[0147] When the guide vane 120 is rotatably connected to the support plate 110, the guide vane 120 may also include a rotating shaft 122. The rotating shaft 122 is connected to the blade body 121, and the rotating shaft 122 may be integrally formed on the blade body 121 to form an integrally formed guide vane 120. The rotating shaft 122 may be connected to the end of the blade body 121 facing the support plate 110, and the rotating shaft 122 is rotatably connected to the support plate 110, and the blade body 121 rotates around the rotating shaft 122.

[0148] For example, the rotation shaft 122 can be located on the central axis of the blade body 121. This results in better force balance for the guide vanes 120, leading to improved stability and reliability during rotation. Furthermore, the consistent width of the blade body 121 on both sides of the central axis facilitates the layout and installation of the guide vanes 120. The spacing between adjacent blades can be designed based on the width of the blade body 121, ensuring even spacing between the guide vanes 120. Additionally, the guide vanes 120 are better suited for 360° rotation scenarios, minimizing their range of motion and the required space, thus reducing the space occupied by the air handling assembly 20 and contributing to the miniaturization of the air handling equipment 1.

[0149] For example, the rotating shaft 122 may include a disc structure (not shown in the figure), and the support plate 110 may be provided with a mounting groove (not shown in the figure). The disc structure can rotate within the mounting groove to allow the guide vane 120 to rotate on the support plate 110. The disc structure can be completely accommodated within the mounting groove. For example, the disc structure is flush with the front surface of the support plate 110 (the side of the support plate 110 facing the blade body 121). This prevents the disc structure from protruding from the surface of the support plate 110, helping to reduce the wind resistance of the adjustment assembly 100. Furthermore, the adjustment assembly 100 has better flatness and is more aesthetically pleasing.

[0150] Figure 6 for Figure 2 The main view of the air guide component. Figure 7 for Figure 6 A magnified view of a section where the guide vanes at point A are in a vertical position. (Combined with...) Figure 6 and Figure 7 As shown, this embodiment also designs the shape of the air guide blade 120 in the adjustment component 100. The air guide blade 120 is used to further adjust the air delivery direction, enhance the flexibility of the adjustment component 100 in adjusting the air delivery area, and further expand the air delivery coverage area of ​​the air guide component 20.

[0151] For ease of explanation, in this embodiment, the opposite sides of the blade body 121 of the guide vane 120 are defined as the first guide side 1211 and the second guide side 1212, respectively. The first guide side 1211 and the second guide side 1212 are located on both sides of the central axis of the blade body 121. When the air handling equipment 1 is in operation and the guide vane 120 is in the open air outlet 11 state, one of the first guide side 1211 and the second guide side 1212 of the blade body 121 is located in the inner position of the air outlet 11, and the other is located in the outer position of the air outlet 11.

[0152] Specifically, in this embodiment, at least a portion of the air guide vanes 120 in the adjustment assembly 100 are configured with curved blade bodies 121. For these curved blade bodies 121, the central axis of the blade body 121 is used as the dividing line. On one side of the central axis, the blade body 121 has a first curved portion 1213, and the first air guide side 1211 is the side of the first curved portion 1213 away from the central axis of the blade body 121.

[0153] By designing a first curved portion 1213 on one side of the blade body 121 along the central axis, the first curved portion 1213 causes the first guide side 1211 to deflect towards one side of the blade body 121. Taking the reference plane A of the blade body 121 as a reference, the extension direction of the first guide side 1211 deviates from the reference plane A, and the extension line of the first guide side 1211 forms a first angle α with the reference plane A (see...). Figure 7 (As shown).

[0154] The reference plane A of the blade body 121 is the orthographic projection plane of the blade body 121, which is formed by orthographically projecting the blade body 121. Furthermore, the reference plane A of the blade body 121 includes the central axis of the blade body 121; in other words, the central axis of the blade body 121 passes through the reference plane A. It can be understood that when the blade body 121 is planar, the plane containing the blade body 121 is the reference plane A.

[0155] When the air handling unit 1 is in operation, an air guide channel is formed between the blade bodies 121 of adjacent guide vanes 120, and the airflow at the outlet 11 is blown to the outside along the air guide channel. Since one side of the blade body 121 is a first bend 1213, the first bend 1213 can generate a Coanda effect in the airflow passing through the air guide channel, changing the direction of the airflow. In turn, the air delivery direction of the regulating component 100 is changed, and the air delivery area of ​​the air guide component 20 is adjusted.

[0156] The Coanda effect, also known as the wall adhesion effect or Coanda effect, is a phenomenon in fluid mechanics. Specifically, it manifests as a fluid (water or air) deviating from its original flow direction and instead flowing along a convex surface. When surface friction (or fluid viscosity) exists between the fluid and the surface it flows over, the fluid will flow along that surface as long as the curvature is not too large.

[0157] Therefore, when the airflow in the duct flows towards the outlet 11, it passes over the surface of the first bend 1213, and friction occurs between the airflow and the surface of the first bend 1213. This changes the direction of the airflow, causing it to flow along the surface of the first bend 1213. Finally, when the airflow is blown to the outside through the blade body 121, it can flow along the extension direction of the first guide side 1211. In other words, the extension direction of the first guide side 1211 can be considered as the air delivery direction of the guide blade 120.

[0158] This configuration guides the airflow direction of the outlet 11 via the first guide side 1211, causing the airflow to flow along the extension direction of the first guide side 1211. The extension line of the first guide side 1211 and the reference plane A containing the blade body 121 form a first angle, effectively changing the direction of the airflow that would normally flow along the extension direction of the reference plane A. Furthermore, this allows for adjustment of the air delivery angle of the regulating component 100, making the air delivery area more flexible and further expanding the air delivery coverage area of ​​the air handling unit 1.

[0159] When the air handling unit 1 is in operation, the first curved portion 1213 in the blade body 121 can be close to the outer side of the air outlet 11, and the first air guide side 1211 is the side where the airflow exits the air guide channel. In this way, the airflow flows along the surface of the first curved portion 1213, and when the airflow is blown to the outside, it can flow along the extension direction of the first air guide side 1211, thereby changing the air delivery direction of the regulating component 100.

[0160] Furthermore, in order to expand the air delivery area of ​​the adjustment component 100, when the first air guide side 1211 faces outward from the air outlet 11, the first curved portion 1213 can cause the first air guide side 1211 to deflect towards the same side of the air outlet 11. (Refer to...) Figure 7 As shown, with the guide vane 120 in a vertical position as a reference, when the guide vane 120 is perpendicular to the plane of the air outlet 11, the extension line of the first guide side 1211 can extend to the same side of the air outlet 11. Taking the position of the guide vane 120 closer to the left side of the length direction of the air outlet 11 as an example, the first guide side 1211 can be tilted to the left side of the air outlet 11. When the guide vane 120 is perpendicular to the plane of the air outlet 11, the extension line of the first guide side 1211 can extend to the left side of the air outlet 11.

[0161] To ensure the regulating assembly 100 has a large air supply coverage area, the guide vanes 120 are typically directed to the same side as the air outlet 11. For example, the guide vanes 120 on the left side of the length direction of the air outlet 11 direct airflow to the left side of the air outlet 11, and the guide vanes 120 on the right side of the length direction of the air outlet 11 direct airflow to the right side of the air outlet 11. By extending the extension line of the first guide side 1211 to the same side of the air outlet 11, when the first guide side 1211 faces outward from the air outlet 11, the air supply deflection angle of the guide vanes 120 can be further increased when the guide vanes 120 direct airflow to the same side of the air outlet 11. This, in turn, expands the air supply area of ​​the regulating assembly 100.

[0162] The airflow guidance of the aforementioned guide vanes to the same side of the air outlet is illustrated by the following two examples: For the guide vane 120 located on the left side of the length direction of the air outlet 11, when the guide vane 120 guides airflow to the left side of the air outlet 11, the first guide side 1211 can further deflect the airflow angle of the guide vane 120 to the left side of the air outlet 11. For the guide vane 120 located on the right side of the length direction of the air outlet 11, when the guide vane 120 guides airflow to the right side of the air outlet 11, the first guide side 1211 can further deflect the airflow angle of the guide vane 120 to the right side of the air outlet 11. This increases the airflow deflection angle of the air guide assembly 20 to both sides of the air outlet 11, expanding the airflow area and coverage of the air guide assembly 20.

[0163] Of course, in some embodiments, when the air handling device 1 is in operation, the first curved portion 1213 in the blade body 121 may also face inward towards the air outlet 11, and the first guide side 1211 is the side where the airflow flows into the guide channel. In this way, the airflow direction can be changed when the airflow flows into the guide channel. After the airflow flows along the surface of the first curved portion 1213 in the guide channel, the airflow direction is changed. Furthermore, the airflow direction after flowing out of the guide blade 120 is also changed, thereby changing the air delivery direction of the regulating component 100.

[0164] At this time, in order to expand the air supply area of ​​the adjustment component 100, the first curved portion 1213 can also deflect the first guide side 1211 toward the same side of the air outlet 11. When the guide blade 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the first guide side 1211 can extend toward the same side inside the air outlet 11. In this way, when the guide blade 120 needs to guide air toward the same side of the air outlet 11, the extension line of the first guide side 1211 of the guide blade 120 is made perpendicular to the plane where the air outlet 11 is located, or the extension line of the first guide side 1211 of the guide blade 120 is deflected toward the other side of the air outlet 11, so as to ensure that when the airflow flows outward from the air outlet 11, the overall flow is biased toward the same side of the air outlet 11.

[0165] Taking the guide vane 120 located on the left side of the air outlet 11 along its length as an example, when the guide vane 120 guides air to the left side of the air outlet 11, the extension line of the first guiding side 1211 of the guide vane 120 towards the inside of the air outlet 11 can be perpendicular to the plane of the air outlet 11. Alternatively, the extension line of the first guiding side 1211 of the guide vane 120 can extend inward towards the air outlet 11 and be deflected to the right side of the air outlet 11. In this way, the guide vane 120 as a whole is deflected to the left side of the air outlet 11, which can achieve air guidance to the left side of the air outlet 11.

[0166] Thus, using the centerline along the length of the air outlet 11 as a boundary, when the air handling unit 1 is operating, the guide vane 120 located on the left side of the air outlet 11 can deflect to the left (for example, the guide vane 120 in the left adjustment component 100 of the two adjustment components 100 deflects to the left). Through the guiding effect of the first bend 1213, the air delivery angle and air delivery area to the left side of the air outlet 11 are expanded. Simultaneously, the guide vane 120 located on the right side of the air outlet 11 can deflect to the right (for example, the guide vane 120 in the right adjustment component 100 of the two adjustment components 100 deflects to the right). Through the guiding effect of the first bend 1213, the air delivery angle and air delivery area to the right side of the air outlet 11 are expanded. Therefore, the air delivery coverage area of ​​the air handling unit 1 is significantly expanded.

[0167] Alternatively, the guide vanes 120 on both sides of the air outlet 11 can be deflected to the left (for example, the guide vanes 120 in both adjustment components 100 are deflected to the left). In this case, the angle at which all the guide vanes 120 on the left side of the air outlet deflect to the left is increased. Furthermore, the support plate 110 in the right adjustment component 100 can be deflected to the left, causing the guide vanes 120 on it to deflect to the left by an increased angle. Even the support plate 110 in the left adjustment component 100 can be deflected to the left, causing the guide vanes 120 on it to deflect to the left by an increased angle. Therefore, the angle at which the air handling unit 1 directs air to the left has a significant increase.

[0168] Similarly, the guide vanes 120 located on both sides of the air outlet 11 can all deflect to the right (for example, the guide vanes 120 in both adjustment components 100 deflect to the right). At this time, the angle at which all the guide vanes 120 on the right side of the air outlet deflect to the right is increased. Furthermore, the support plate 110 in the left adjustment component 100 can also deflect to the right, causing the guide vanes 120 on it to deflect to the right at an increased angle. Even more significantly, the support plate 110 in the right adjustment component 100 can also deflect to the right, causing the guide vanes 120 on it to deflect to the right at an increased angle. Therefore, the angle at which the air handling unit 1 directs air to the right has a significant increase.

[0169] The following description will be based on the example where, when the air handling equipment 1 is in operation, the first curved portion 1213 of the blade body 121 of the air guide vane 120 faces the outside of the air outlet 11, and the first air guide side 1211 is deflected to the same side as the air outlet 11.

[0170] Specifically, taking a guide vane 120 located on the left side of the air outlet 11 along its length as an example, if the first angle α between the extension line of the first guide side 1211 of the guide vane 120 and its reference plane A is 30°, when the guide vane 120 is perpendicular to the plane of the air outlet 11, the angle between the extension line of its first guide side 1211 and the perpendicular line of the air outlet 11 (the line perpendicular to the plane of the air outlet 11) is 30°, thus achieving a 30° leftward deflection of the air delivery angle of the guide vane 120. When the guide vane 120 deflects 15° to the left, the angle between the extension line of its first guide side 1211 and the perpendicular line of the air outlet 11 is 45°, thus achieving a 45° leftward deflection of the air delivery angle of the guide vane 120.

[0171] Thus, when the guide vane 120 guides air to the same side of the outlet 11, the blade body 121 of the guide vane 120 deflects at a certain angle to the same side of the outlet 11. Combined with the angle between the first guide side 1211 of the blade body 121 and the reference plane A, this results in a larger deflection angle of the first guide side 1211 to the same side of the outlet 11. This increases the air delivery angle of the blade body 121, resulting in a larger air delivery area and wider air delivery coverage of the adjustment assembly 100.

[0172] Meanwhile, with a fixed air delivery angle for the guide vane 120, the deflection angle of the blade body 121 is the required air delivery angle minus the first included angle α between the first guide side 1211 of the blade body 121 and the reference plane A, resulting in a smaller required deflection angle for the blade body 121. This leads to a smaller rotation angle for the drive motor 201 to drive the blade body 121, resulting in less energy consumption for the drive motor 201, which helps save energy consumption of the adjustment component 100 and reduce the overall energy consumption of the air handling equipment 1.

[0173] Continue to refer to Figure 7 In some embodiments, in addition to designing one side of the blade body 121 as a first curved portion 1213, the other side of the blade body 121 can also be designed as a second curved portion 1214. That is, both sides of the central axis of the blade body 121 are designed as curved portions. Among them, the side of the second curved portion 1214 away from the central axis of the blade body 121 is the second guide side 1212 of the blade body 121. The extension direction of the second guide side 1212 also deviates from the reference plane A, and the extension line of the second guide side 1212 has a second included angle β with the reference plane A.

[0174] Thus, when the blade body 121 rotates to the outer side of the second curved portion 1214 near the air outlet 11 and the second air guide side 1212 faces the outside of the air outlet 11, the airflow in the air guide channel flows along the surface of the second curved portion 1214. When the airflow is blown to the outside, it can flow along the extension direction of the second air guide side 1212, thereby changing the air delivery direction of the regulating component 100.

[0175] Figure 8 for Figure 6 A magnified view of a section where the guide vane at point A is in a different vertical position. (Refer to...) Figure 8 As shown, similar to the first curved portion 1213, when the second air guide side 1212 faces outward from the air outlet 11, the second curved portion 1214 can cause the second air guide side 1212 to deflect to the same side of the air outlet 11. Figure 8With the guide vane 120 in a reverse vertical position as a reference, when the guide vane 120 is perpendicular to the plane of the air outlet 11, the extension line of the second guide side 1212 can extend to the same side of the air outlet 11. Taking the position of the guide vane 120 closer to the left side of the length direction of the air outlet 11 as an example, the second guide side 1212 can be tilted to the left side of the air outlet 11. When the guide vane 120 is perpendicular to the plane of the air outlet 11, the extension line of the second guide side 1212 can extend to the left side of the air outlet 11.

[0176] Thus, when the second air guide side 1212 faces outward from the air outlet 11, and the air guide blade 120 guides air to the same side of the air outlet 11, the second air guide side 1212 can further increase the air delivery deflection angle of the air guide blade 120. This, in turn, expands the air delivery area of ​​the adjustment assembly 100.

[0177] Meanwhile, given a fixed air delivery angle for the guide vane 120, the deflection angle of the blade body 121 is the required air delivery angle minus the second included angle β between the second guide side 1212 of the blade body 121 and the reference plane A. This results in a smaller required deflection angle for the blade body 121. Consequently, the angle at which the drive motor 201 drives the blade body 121 to rotate is smaller, leading to lower energy consumption for the drive motor 201 and thus saving energy for the adjustment assembly 100. Further details are omitted here.

[0178] like Figure 7 As shown, with the plane where the air guide blade 120 is perpendicular to the air outlet 11 as a reference, when the first air guide side 1211 faces the outside of the air outlet 11, the extension line of the first air guide side 1211 extends to the same side of the air outlet 11. At this time, the second air guide side 1212 faces the inside of the air outlet 11, and the extension line of the second air guide side 1212 extends to the opposite side of the air outlet 11. Taking the left side of the air guide blade 120 near the air outlet 11 as an example, the extension line of the first air guide side 1211 facing outwards from the air outlet 11 can extend to the left side of the air outlet 11, and the extension line of the second air guide side 1212 facing inwards from the air outlet 11 can extend to the right side of the air outlet 11.

[0179] like Figure 8 As shown, when the second air guide side 1212 faces the outside of the air outlet 11, the extension line of the second air guide side 1212 extends to the same side of the air outlet 11. At this time, the first air guide side 1211 faces the inside of the air outlet 11, and the extension line of the first air guide side 1211 extends to the opposite side of the air outlet 11. Taking the left side of the air guide blade 120 near the air outlet 11 as an example, the extension line of the second air guide side 1212 facing outwards from the air outlet 11 can extend to the left side of the air outlet 11, and the extension line of the first air guide side 1211 facing inwards from the air outlet 11 can extend to the right side of the air outlet 11.

[0180] When the air handling unit 1 is operating, the guide vanes 120 can be in a first open state. In this state, the first guide side 1211 of the guide vanes 120 faces outwards from the air outlet 11, and the second guide side 1212 faces inwards from the air outlet 11. Alternatively, the guide vanes 120 can be in a second open state. In this state, the second guide side 1212 of the guide vanes 120 faces outwards from the air outlet 11, and the first guide side 1211 faces inwards from the air outlet 11.

[0181] With this configuration, the air guide vane 120 can increase the airflow deflection angle using both the first air guide side 1211 and the second air guide side 1212. This eliminates limitations on the rotation angle of the air guide vane 120, making its control more flexible and its operation simpler.

[0182] Figure 9 for Figure 6 A magnified view of the guide vane at point A. (Refer to...) Figure 9 As shown, in some embodiments, the degree of curvature of the first curved portion 1213 may be greater than the degree of curvature of the second curved portion 1214. Furthermore, comparing the first included angle α between the extension line of the first air guide side 1211 and the reference plane A, and the second included angle β between the extension line of the second air guide side 1212 and the reference plane A, the angle of the first included angle α is greater than the angle of the second included angle β.

[0183] With this configuration, when the guide vane 120 is in the first open state, with the first guide side 1211 of the guide vane 120 facing outwards from the air outlet 11, the airflow flowing out of the guide channel deflects at a relatively larger angle towards the same side of the air outlet 11. Conversely, when the guide vane 120 is in the second open state, with the second guide side 1212 of the guide vane 120 facing outwards from the air outlet 11, the airflow flowing out of the guide channel deflects at a relatively smaller angle towards the same side of the air outlet 11.

[0184] Therefore, users can adjust the opening state of the air guide vanes 120 according to actual needs, so that the first air guide side 1211 of the air guide vanes 120 faces outward or the second air guide side 1212 of the air guide vanes 120 faces outward, to obtain different air delivery directions and air delivery areas. The adjustment component 100 can more flexibly adjust the air delivery coverage range, which can improve the user experience of the air handling equipment 1.

[0185] Furthermore, due to the inconsistent curvature of the first curved portion 1213 and the second curved portion 1214, the skewness of the first air guide side 1211 is greater than that of the second air guide side 1212. The different structures on both sides of the central axis of the air guide blade 120 facilitate the identification and installation of the air guide blade 120. When assembling the adjustment assembly 100, the first air guide side 1211 of each air guide blade 120 can be arranged to face one side of the support plate 110, and the second air guide side 1212 of each air guide blade 120 can be arranged to face the other side of the support plate 110, ensuring the correct assembly of the adjustment assembly 100 and reducing the probability of rework and scrapping of the adjustment assembly 100.

[0186] Especially when the first curved portion 1213 is close to the outside of the air outlet 11 and the first guide side 1211 faces the outside of the air outlet 11, the large curvature of the first curved portion 1213 and the large deflection angle of the first guide side 1211 allow the airflow to better utilize the Coanda effect and expand the air outlet angle of the guide vane 120 as it flows along the first curved portion 1213 to the first guide side 1211 and is then directed outwards. Simultaneously, when the second curved portion 1214 is close to the inside of the air outlet 11 and the second guide side 1212 faces the inside of the air outlet 11, the small curvature of the second curved portion 1214 and the large deflection angle of the second guide side 1212 further reduce the wind resistance in the airflow channel, increase the gas velocity in the airflow channel, and improve the airflow efficiency of the guide vane 120.

[0187] For example, the difference between the first included angle α and the second included angle β can be between 6° and 12°. On the one hand, there is a significant angle difference between the first included angle α and the second included angle β. When the guide vanes are at the same deflection angle, the air delivery direction and air delivery area of ​​the adjusting component 100 are significantly different when the first guide side 1211 faces outward from the air outlet 11 and the second guide side 1212 faces outward from the air outlet. On the other hand, the angle difference between the first included angle α and the second included angle β will not be too large. The overall smoothness of the guide vane 120 is good, there are no excessively bent parts, and stress concentration will not occur, which can ensure the overall reliability and service life of the guide vane 120.

[0188] For example, the difference between the first included angle α and the second included angle β is 6.5°, 7.0°, 7.5°, 8.0°, 8.5°, 9.0°, 9.5°, 10.0°, 10.5°, 11.0°, and 11.5°.

[0189] In other embodiments, the bending shape of the second curved portion 1214 can be completely consistent with the bending shape of the first curved portion 1213, and the blade body 121 of the guide vane 120 has a centrally symmetrical structure. When the rotation axis 122 of the guide vane 120 is located on the central axis of the blade body 121, the guide vane 120 as a whole has a centrally symmetrical structure. At this time, comparing the first included angle α between the extension line of the first guide side 1211 and the reference plane A, and the second included angle β between the extension line of the second guide side 1212 and the reference plane A, the angle of the first included angle α is equal to the angle of the second included angle β.

[0190] In this way, whether the first air guide side 1211 is located outside the air outlet 11 or the second air guide side 1212 is located outside the air outlet 11, when the blade body 121 is deflected to a certain angle, the air delivery deflection angle of the air guide blade 120 is the same, which allows the air guide blade 120 to have the same air delivery adjustment effect. Furthermore, the air guide blade 120 has good structural symmetry, balanced force, better stability, and higher reliability. In addition, because the air guide blade 120 has a symmetrical structure, it is more operable during installation, eliminating the need to differentiate the positioning of the two sides of the air guide blade 120, resulting in higher installation efficiency and a better appearance of the adjustment assembly 100.

[0191] Additionally, refer to Figure 7 or Figure 8 In some embodiments, the blade body 121 also has a straight portion 1218, which is located between the first curved portion 1213 and the second curved portion 1214, and the two ends of the straight portion 1218 are respectively connected to the first curved portion 1213 and the second curved portion 1214.

[0192] In this way, the blade body 121 can guide airflow through the first curved portion 1213 and the second curved portion 1214 on both sides, thereby expanding the air delivery coverage of the guide vane 120. Simultaneously, the smoothness of the straight portion 1218 in the middle of the blade body 121 is better, which can reduce wind resistance within the air guide channel and increase the gas velocity flowing out of the outlet 11. Furthermore, the straight portion 1218 has a better effect on dispersing air pressure, which can make the stress on the blade body 121 more uniform, improving the reliability and service life of the blade body 121.

[0193] Taking the end where the straight portion 1218 connects to the first curved portion 1213 as its first end, and the end where the straight portion 1218 connects to the second curved portion 1214 as its second end, the first end of the straight portion 1218 can extend along the tangent direction of the first curved portion 1213, and the second end of the straight portion 1218 can extend along the tangent direction of the second curved portion 1214. In this way, there is a straight transition between the straight portion 1218 and the first curved portion 1213, and between the straight portion 1218 and the second curved portion 1214, resulting in better overall smoothness of the blade body 121, lower wind resistance, and more uniform stress.

[0194] In other embodiments, only one side of the blade body 121 may be designed as the first curved portion 1213, while the other side of the blade body 121 may be designed as a straight portion. For example, the extension direction of the straight portion may be designed based on the reference plane A of the blade body 121, the straight portion may extend along the extension direction of the reference plane A, and the center plane of the straight portion in the thickness direction may be located within the reference plane A.

[0195] When one side of the blade body 121 is a first curved portion 1213 and the other side is a straight portion, when installing the guide vane 120, the first guiding side 1211 of the guide vane 120 can be oriented towards the outside of the air outlet 11. Furthermore, the rotation angle range of the guide vane 120 can be controlled so that the first curved portion 1213 of the blade body 121 is always located outside the air outlet 11, while the straight portion of the blade body 121 is always located inside the air outlet 11. This allows the first guiding side 1211 to guide the airflow and change the air delivery angle of the guide vane 120.

[0196] Of course, as mentioned above, the straight portion of the blade body 121 can also be located outside the air outlet 11, while the first curved portion 1213 of the blade body 121 can be located inside the air outlet 11, using the first curved portion 1213 to adjust the flow direction of the airflow entering the air guide channel. This changes the air delivery angle of the guide blade 120. Further details will not be elaborated here.

[0197] Regarding the architectural design of all the guide vanes 120 in the entire regulating assembly 100, all the guide vanes 120 can be designed as curved surfaces. In this way, the first air guiding side 1211 of all the guide vanes 120 can increase the air delivery deflection angle of the guide vanes 120. This can change the air delivery angle of the entire regulating assembly 100, thereby increasing the deflection angle of the entire air delivery area of ​​the regulating assembly 100.

[0198] Alternatively, some of the guide vanes 120 can be designed as curved surfaces, while the rest remain flat. The curved guide vanes 120 can increase the airflow deflection angle of the corresponding area of ​​the regulating component 100. The remaining flat guide vanes 120, on the other hand, allow the corresponding area of ​​the regulating component 100 to maintain its original airflow deflection angle.

[0199] At this point, the guide vanes 120 closer to the end of the air outlet 11 can be designed as curved, while the guide vanes 120 closer to the center of the air outlet 11 can be designed as flat. The air deflection angle of the guide vanes 120 closer to the center of the air outlet 11 is smaller, while the air deflection angle of the guide vanes 120 closer to the end of the air outlet 11 is larger. From the center to the end of the air outlet 11, the air deflection angle of the regulating component 100 increases. In this way, the air delivery area of ​​the regulating component 100 is larger, the air delivery coverage is wider, and the airflow is softer.

[0200] In the regulating component 100, whether only some of the guide vanes 120 are designed with a curved shape or all of the guide vanes 120 are designed with a curved shape, all the guide vanes 120 with curved shapes can maintain a consistent shape. In this way, the curved guide vanes 120 have a consistent air supply regulating effect on the corresponding area of ​​the regulating component 100.

[0201] Alternatively, along the direction near the end of the air outlet 11, that is, from the center of the air outlet 11 to the end of the air outlet 11, the curvature of each of the curved guide vanes 120 can gradually increase. For example, the first angle α between the extension line of the first guide side 1211 of each guide vane 120 and the reference plane A can gradually increase. The second angle β between the extension line of the second guide side 1212 of each guide vane 120 and the reference plane A can also gradually increase.

[0202] In this way, from the center of the air outlet 11 to its end, the air delivery deflection angle of the regulating component 100 gradually increases, resulting in a larger air delivery area and a wider air delivery coverage. Furthermore, the air delivery area gradually expands outward, making the airflow more dispersed and the air delivery gentler.

[0203] See Figure 6Taking the air guide assembly 20 with two adjusting components 100 as an example, when the air handling equipment 1 is working, in the adjusting component 100 located on the left side of the air outlet 11 along its length, the first guiding side 1211 of the curved air guide blade 120 is tilted to the left of the air outlet 11. In the adjusting component 100 located on the right side of the air outlet 11 along its length, the first guiding side 1211 of the curved air guide blade 120 is tilted to the right of the air outlet 11. This can expand the air delivery area of ​​the air guide assembly 20 to the left and right, increasing the air delivery coverage of the air guide assembly 20. In addition, the support plates 110 of the two adjusting components 100 swing outward relative to each other, further expanding the air delivery coverage of the air guide assembly 20.

[0204] The following is a detailed description of the curved guide vane 120.

[0205] The angle α between the extension line of the first guide side 1211 of the guide vane 120 and its reference plane A can range from 5° to 55°. (Refer to...) Figure 7 As shown, taking the first air guide side 1211 facing outwards from the air outlet 11 as an example, and using the plane direction of the air guide blade 120 perpendicular to the air outlet 11 as a reference, when the first angle α between the extension line of the first air guide side 1211 and the reference plane A is 5°, the air delivery direction of the air guide blade 120 deflects 5° towards the same side of the air outlet 11; the air guide blade 120 continues to deflect 85° towards the same side of the air outlet 11, thus achieving the extension line of the first air guide side 1211 parallel to the plane direction of the air outlet 11. When the first angle α between the extension line of the first air guide side 1211 and the reference plane A is 55°, the air delivery direction of the air guide blade 120 deflects 55° towards the same side of the air outlet 11; the air guide blade 120 continues to deflect 35° towards the same side of the air outlet 11, thus achieving the extension line of the first air guide side 1211 parallel to the plane direction of the air outlet 11.

[0206] Thus, when the guide vane 120 guides air through the first guide side 1211, the guide vane 120 only needs to rotate within a small angle range to provide an air delivery area with a large angle range. The guide vane 120 can flexibly adjust the air delivery angle, changing the air delivery area of ​​the adjustment assembly 100. Furthermore, the first included angle α between the extension line of the first guide side 1211 and the reference plane A is not too large, the curvature of the first curved portion 1213 is appropriate, and the guide vane 120 does not obstruct the airflow. The overall wind resistance of the adjustment assembly 100 is very small and will not affect the air delivery volume of the air handling unit 1.

[0207] For example, the angle α between the extension line of the first guide side 1211 and its reference plane A can be between 25° and 55°. By making the first angle α between the extension line of the first guide side 1211 and its reference plane A greater than or equal to 25°, when the guide vane 120 is perpendicular to the plane of the air outlet 11, the deflection angle of the air delivery direction of the guide vane 120 toward the same side of the air outlet 11 is greater than or equal to 25°. The first guide side 1211 can significantly increase the air delivery deflection angle of the guide vane 120, which can better expand the air delivery area of ​​the adjustment assembly 100.

[0208] For example, the first included angle α between the extension line of the first air guide side 1211 and its reference plane A can be 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, etc.

[0209] Continue to refer to Figure 7 The first curved portion 1213 of the blade body 121 can be a smooth curved portion, with a relatively gentle overall curvature. The first curved portion 1213 allows airflow to flow smoothly along its surface, changing the direction of airflow without obstructing it. The airflow flows smoothly out of the air guide channel along the first curved portion 1213, enabling the air handling equipment 1 to stably blow airflow to the outside.

[0210] Furthermore, the first curved portion 1213 may have only one curved apex 12131. That is, the first curved portion 1213 bends only once on one side of the thickness direction of the blade body 121. In order to achieve the first air guide side 1211 deflecting to the same side of the air outlet 11, the first curved portion 1213 may bulge slightly on the other side of the air outlet 11. In this way, the first curved portion 1213 avoids forming a continuously undulating wave surface, so as to prevent the first curved portion 1213 from changing the airflow direction multiple times, thus avoiding affecting the air delivery direction of the air guide blade 120 and ensuring the adjustment effect of the first curved portion 1213 on the air delivery deflection angle of the air guide blade 120. It can also prevent the airflow from becoming turbulent when flowing through the first curved portion 1213, so as to ensure that the airflow can flow out of the air guide blade 120 smoothly and orderly, so as not to lose the air delivery volume of the air handling equipment 1.

[0211] When the first curved portion 1213 has only one curved vertex 12131, the extension line of the first air guiding side 1211 extends toward one side of the reference plane A, while the curved vertex 12131 can be located on the other side of the reference plane A. Taking the air guiding blade 120 on the left side near the length direction of the air outlet 11 as an example, specifically taking the plane where the air guiding blade 120 is perpendicular to the air outlet 11 as a reference, the extension direction of the first air guiding side 1211 of the air guiding blade 120 can extend toward the left side of the reference plane A, while the curved vertex 12131 can be located on the right side of the reference plane A.

[0212] This avoids the extension line of the first guide vane 1211 and the bending apex 12131 of the first bending portion 1213 being located on the same side of the reference plane A, and prevents the first bending portion 1213 from being excessively skewed to one side of the guide vane 120. The guide vane 120 is generally flat with a small degree of curvature, resulting in low wind resistance. During long-term use, the guide vane 120 experiences less pressure from the airflow, leading to higher reliability and a longer service life. Furthermore, the guide vane 120 remains generally flat, occupying less space and facilitating its placement on the support plate 110.

[0213] For example, the centerline of the first air guide side 1211 in the thickness direction can be located on the reference plane A. In this way, the bending shape of the first bending portion 1213 is constrained, limiting the first bending portion 1213 to a smaller bending amplitude, resulting in a smoother blade body 121, less obstruction to the fluid, and better meeting the high-efficiency air delivery requirements of the air handling equipment 1.

[0214] When the other side of the blade body 121 is configured as a second curved section 1214, the angle β between the extension line of the second guiding side 1212 of the guide vane 120 and its reference plane A can range from 5° to 45°. (Refer to...) Figure 8 As shown, taking the second air guide side 1212 facing outwards from the air outlet 11 as an example, and using the plane direction of the air guide blade 120 perpendicular to the air outlet 11 as a reference, when the second included angle β between the extension line of the second air guide side 1212 and the reference plane A is 5°, the air delivery direction of the air guide blade 120 deflects 5° towards the same side of the air outlet 11; if the air guide blade 120 continues to deflect 85° towards the same side of the air outlet 11, the extension line of the second air guide side 1212 will be parallel to the plane direction of the air outlet 11. When the second included angle β between the extension line of the second air guide side 1212 and the reference plane A is 45°, the air delivery direction of the air guide blade 120 deflects 45° towards the same side of the air outlet 11; if the air guide blade 120 continues to deflect 45° towards the same side of the air outlet 11, the extension line of the second air guide side 1212 will be parallel to the plane direction of the air outlet 11.

[0215] Thus, when the guide vane 120 guides air through the first guide side 1211, the guide vane 120 only needs to rotate within a small angle range to provide an air delivery area with a large angle range. Furthermore, the second included angle β between the extension line of the second guide side 1212 and the reference plane A is not excessively large, the curvature of the second bend 1214 is appropriate, and the guide vane 120 does not obstruct airflow. Further details are omitted here.

[0216] For example, the angle β between the extension line of the second air guide side 1212 and its reference plane A can be between 25° and 45°. This allows the second air guide side 1212 to significantly increase the airflow deflection angle of the air guide blades 120, thus better expanding the airflow area of ​​the adjustment assembly 100. For instance, the second angle β between the extension line of the second air guide side 1212 and its reference plane A can be 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, etc.

[0217] Based on this, similar to the first curved portion 1213, the second curved portion 1214 can also be a smooth curved portion. Furthermore, the second curved portion 1214 can also have only one curved vertex 12141. For example, the extension line of the second air guide side 1212 extends towards one side of the reference plane A, while the curved vertex 12141 can be located on the other side of the reference plane A. Additionally, the centerline of the second air guide side 1212 in the thickness direction can be located on the reference plane A. Further details will not be elaborated here.

[0218] When the other side of the blade body 121 is set as a straight section, the centerline of the second guide side 1212 of the blade body 121 in the thickness direction can also be located on the reference plane A. In this way, both sides of the guide blade body 121 are located on its reference plane A, and the overall design of the blade body 121 is more inclined to a planar shape, with a more regular shape, good air guiding effect, good stability, and high reliability.

[0219] Figure 10 A three-dimensional structural diagram of another air guide component provided in an embodiment of this application. Figure 11 for Figure 10 A magnified view of a portion of the air guiding component. Among them, Figure 11 The diagram illustrates the structure of one of the air guide vanes 120 on the regulating assembly 100.

[0220] Reference Figure 10 and Figure 11 As shown, the blade body 121 of the guide vane 120 may also have a plurality of air outlet holes 1215 distributed thereon, the air outlet holes 1215 penetrating both sides of the blade body 121 in the thickness direction. When the blade body 121 is the aforementioned curved shape, a plurality of air outlet holes 1215 may be provided on the blade body 121. When the blade body 121 is planar, a plurality of air outlet holes 1215 may also be provided on the blade body 121. All blade bodies 121 of the adjusting assembly 100 may have air outlet holes 1215 provided thereon.

[0221] By opening several air outlet holes 1215 on the blade body 121, when the air handling equipment 1 is in operation, the airflow blown out of the air duct can flow outward through the air outlet holes 1215 on the blade body 121.

[0222] Specifically, when the guide vanes 120 are in the open state, there is an angle between the guide vanes 120 and the plane containing the air outlet 11, forming an airflow channel between adjacent guide vanes 120. At this time, part of the airflow blown out of the duct will flow outward along the airflow channel, and part of it can flow outward through the air outlet 1215 on the blade body 121. In this way, the air supply effect of the air handling equipment 1 is improved by utilizing the air outlet 1215 on the blade body 121.

[0223] When the air handling unit 1 supplies air outward through the regulating component 100, in addition to generating a first airflow flowing outward along the air guide channel, a second airflow also flows outward through the air outlet 1215. The direction of the second airflow is different from that of the first airflow. Under the counteracting effect of the second airflow on the first airflow, the flow rate of the first airflow can be slowed down, preventing strong winds from being blown out of the air outlet 11. This makes the air supply effect of the air handling unit 1 gentler and improves the user comfort of the air handling unit 1.

[0224] It should be noted that the diameter of the air outlet 1215 on the blade body 121 is small, and the airflow in the duct will still preferentially flow outward through the air guide channel between adjacent guide blades 120. Therefore, most of the airflow in the duct will flow out through the air guide channel between adjacent guide blades 120, and only a small portion of the airflow will flow out through the air outlet 1215. This small portion of airflow passing through the air outlet 1215 can play a good role in counteracting and mixing the airflow, thereby reducing the outlet airflow velocity. At the same time, it will not have a significant impact on the overall air supply direction and air supply area of ​​the regulating component 100, thus ensuring the air supply regulation effect of the regulating component 100.

[0225] When the guide vanes 120 are closed, they are generally parallel to the plane of the air outlet 11. All guide vanes 120 of the adjusting assembly 100 can be located on the same straight line, with only a small installation gap between adjacent guide vanes 120. At this time, the airflow blowing out of the duct flows outward primarily through the air outlet holes 1215 on the vane body 121. Because the diameter of the air outlet holes 1215 is small and the opening area of ​​the vane body 121 is limited, the airflow rate from the air outlet holes 1215 of each guide vane 120 is relatively small, resulting in a smaller air volume and lower air velocity in the air handling unit 1.

[0226] For example, when the air handling unit 1 is heating, the air guide vanes 120 can be closed, and hot air is delivered outward solely through the air outlets 1215 on each air guide vane 120. Because the hot air velocity is low, the air resistance of the vane body 121 to the hot air is small, and the hot air can be stably output outward through the air outlets 1215 on the vane body 121. Furthermore, by outputting hot air only through the air outlets 1215 on the vane body 121, the flow rate of the hot air can be limited, maintaining the indoor space at a suitable temperature and reducing the energy consumption of the air handling unit 1.

[0227] The air outlets 1215 are evenly distributed on the surface of the blade body 121. This ensures sufficient opening area on the blade body, allowing the second airflow passing through the air outlets 1215 to have sufficient volume, effectively reducing the velocity of the first airflow and softening the airflow from the air handling unit 1. Furthermore, because the air outlets 1215 are evenly distributed across the blade body 121, the pressure exerted by the second airflow on the blade body 121 is evenly distributed, resulting in good stress uniformity and improving the reliability and service life of the blade body 121.

[0228] For example, the air outlets 1215 can be arrayed on the surface of the blade body 121. Multiple rows of air outlets 1215 are arranged sequentially along the height direction of the blade body 121 (the height direction of the blade body 121 is, for example, the width direction of the air outlets 1215), with each row including multiple air outlets 1215 arranged sequentially along the width direction of the blade body 121. Adjacent rows of air outlets 1215 can be staggered, wherein each air outlet 1215 in one row can be located between two adjacent air outlets 1215 in another row.

[0229] The area occupied by the air outlet 1215 on the blade body 121 can be 45%-85% of the total area of ​​the blade body 121, that is, the opening rate of the blade body 121 can be 45%-85%. In this way, the blade body 121 has a sufficient opening area to ensure that the flow area of ​​the blade body 121 itself is sufficient, and the airflow flowing out through the air outlet 1215 of the blade body 121 reaches a certain flow rate, which can achieve an effective air softening effect.

[0230] For example, the opening ratio of the blade body 121 can be between 50% and 60%. In this way, more than half of the area of ​​the blade body 121 is occupied by the air outlet 1215, ensuring sufficient airflow through the air outlet 1215. Furthermore, this avoids an excessively large opening ratio in the blade body 121, meeting the requirements for the opening processing of the blade body 121 and guaranteeing the structural strength and reliability of the blade body 121.

[0231] Figure 12 This is a cross-sectional view of the air guide vane provided in an embodiment of this application. (Refer to...) Figure 12 As shown in the figure, the guide vane 120 is cut off in the middle area of ​​a row of air outlets 1215 along the width direction of the guide vane 120. Based on the air outlets 1215 on the blade body 121, this embodiment also designs the extension direction of the air outlets 1215. The air outlets 1215 do not extend along the thickness direction of the blade body 121, but are designed to extend at an angle.

[0232] For ease of explanation, in this embodiment, the two side surfaces in the thickness direction of the blade body 121 are defined as the first surface 1216 and the second surface 1217, respectively. The first surface 1216 is the side where the extension direction of the extension line of the first guide vane 1211 lies. That is, when the guide vane 120 is in the open state and tilted towards the same side of the air outlet 11, the first surface 1216 of the blade body 121 faces the inner side of the air outlet 11, while the second surface 1217 of the blade body 121 faces the outer side of the air outlet 11 (see [reference]). Figure 6 (As shown).

[0233] Taking the guide vane 120 located on the left side of the air outlet 11 along its length as an example, when the guide vane 120 is in the open state and tilted to the left of the air outlet 11, the air delivery angle of the guide vane 120 deflects to the left of the air outlet 11. At this time, the first guide side 1211 of the blade body 121 faces the outside of the air outlet 11, the second guide side 1212 of the blade body 121 faces the inside of the air outlet 11, and the first surface 1216 of the blade body 121 faces the inside of the air outlet 11, while the second surface 1217 of the blade body 121 faces the outside of the air outlet 11. The extension line of the first guide side 1211 extends to the left of the air outlet 11, that is, the extension line of the first guide side 1211 extends towards the side where the first surface 1216 is located.

[0234] In this embodiment, from the first surface 1216 to the second surface 1217 of the blade body 121, the air outlet 1215 can be tilted toward the side where the first air guide side 1211 of the blade body 121 is located. That is, the central axis of the air outlet 1215 extends tilted toward the first air guide side 1211, and the angle between the central axis of the air outlet 1215 and the reference plane A of the blade body 121 on the side where the first air guide side 1211 is located is less than 90°, while the angle between the central axis of the air outlet 1215 and the reference plane A of the blade body 121 on the side where the second air guide side 1212 is located is greater than 90°.

[0235] Thus, when the guide vanes 120 are in the open state, in the air supply direction of the adjusting assembly 100, the angle between the extending direction of the air outlet 1215 and the side of the blade body 121 near the air outlet 11 is an acute angle, and the air outlet direction of the air outlet 1215 tends to be in the guiding direction of the blade body 121. The directional difference between the direction of the first airflow flowing outward along the air guide channel between adjacent guide vanes 120 and the direction of the second airflow flowing outward through the air outlet 1215 is less than 90°.

[0236] When the guide vanes 120 deflect to the same side as the air outlet 11, and the first airflow from the guide channel between adjacent guide vanes 120 deflects to the same side as the air outlet 11, the second airflow from the air outlet 1215 of the blade body 121, while not significantly deflected to the same side as the air outlet 11, also does not significantly deflect to the other side of the air outlet 11. Simultaneously, the flow rate of the second airflow is significantly less than that of the first airflow. Therefore, the second airflow has a smaller impact on the overall airflow direction of the regulating component 100, ensuring the accuracy of the regulating component 100 in adjusting the airflow direction and airflow area.

[0237] Taking the guide vane 120 on the left side near the air outlet 11 as an example, when the guide vane 120 deflects to the left side of the air outlet 11, the first airflow flowing out from the air guide channel between adjacent guide vanes 120 deflects to the left side of the air outlet 11, and the flow direction of the second airflow flowing out from the air outlet hole 1215 of the blade body 121 can be roughly towards the front of the air outlet 11, or the flow direction of the second airflow can also be slightly deflected to the left side of the air outlet 11.

[0238] Therefore, by tilting the air outlet 1215 on the blade body 121 towards the first air guide side 1211 from the first surface 1216 to the second surface 1217, the second airflow flowing out of the air outlet 1215 can counteract the first airflow flowing out along the air guide channel, making the air delivery of the regulating component 100 more gentle. At the same time, it can also reduce the interference of the second airflow on the overall air delivery direction of the regulating component 100, ensuring the air delivery regulation accuracy of the regulating component 100.

[0239] Specifically, the angle between the extension direction of the air outlet 1215 on the blade body 121 and the reference plane A is in the range of 30°-60°.

[0240] Using a deflection angle of 45° between the blade body 121 and the same side of the air outlet 11 as a reference, the angle between the blade body 121 and the perpendicular direction of the air outlet 11 (the direction perpendicular to the plane where the air outlet 11 is located) is 45°, and the angle between the blade body 121 and the plane direction of the air outlet 11 is also 45°. At this time, the degree of deflection of the blade body 121 is moderate, and the air supply angle of the adjusting component 100 is significantly deflected to the same side of the air outlet 11. Using this deflection angle to judge whether the air outlet direction of the air outlet 1215 is appropriate is more suitable.

[0241] Taking the guide vane 120 on the left side near the air outlet 11 as an example, when the angle between the extension direction of the air outlet 1215 and the reference plane A is 60°, the deflection angle of the blade body 121 towards the left side of the air outlet 11 is 45°, and the airflow blown out of the air outlet 1215 deflects 15 degrees to the right side of the air outlet 1215. When the angle between the extension direction of the air outlet 1215 and the reference plane A is 30°, the deflection angle of the blade body 121 towards the left side of the air outlet 11 is 45°, and the airflow blown out of the air outlet 1215 deflects 15 degrees to the left side of the air outlet 1215.

[0242] Therefore, the smaller the angle between the extension direction of the air outlet 1215 and the reference plane A, the closer the air outlet direction of the air outlet 1215 is to the overall air supply direction of the regulating component 100. Furthermore, when the deflection angle of the blade body 121 towards the same side of the air outlet 11 is greater than 45°, it indicates that the regulating component 100 has a more significant effect on guiding airflow towards the same side of the air outlet 11. Therefore, by designing the angle between the extension direction of the air outlet 1215 and the reference plane A to be less than or equal to 60°, when the regulating component 100 guides airflow towards the same side of the air outlet 11, the airflow from the air outlet 1215 will not be significantly directed towards the other side of the air outlet 11, resulting in a better overall regulating effect of the regulating component 100.

[0243] For example, the angle between the extending direction of the air outlet 1215 on the blade body 121 and the reference plane A ranges from 40° to 50°. Continuing with the example of the guide blade 120 near the left side of the air outlet 11, when the angle between the extending direction of the air outlet 1215 and the reference plane A is 50°, the deflection angle of the blade body 121 towards the left side of the air outlet 11 is 45°, and the second airflow blown from the air outlet 1215 deflects 5 degrees to the right side of the air outlet 1215. When the angle between the extending direction of the air outlet 1215 and the reference plane A is 30°, the deflection angle of the blade body 121 towards the left side of the air outlet 11 is 45°, and the second airflow blown from the air outlet 1215 deflects 15 degrees to the left side of the air outlet 1215.

[0244] Thus, when the air supply angle of the regulating component 100 is significantly deflected to the same side as the air outlet 11, the second airflow blown from the air outlet 1215 of the blade body 121 is roughly directed towards the front of the air outlet 11, or the second airflow blown from the air outlet 1215 is also deflected to the same side as the air outlet 11. This avoids the air outlet 1215 affecting the overall air supply direction of the regulating component 100. Furthermore, the tilt of the air outlet 1215 is not too large, facilitating the machining of the air outlet 1215 on the blade body 121. In addition, the space occupied by the air outlet 1215 in the planar direction of the blade body 121 is moderate, allowing for the machining of a sufficient number of air outlets 1215 on the blade body 121 to ensure the air supply volume of the air outlets 1215 on the blade body 121.

[0245] For example, the angle between the extending direction of the air outlet 1215 on the blade body 121 and the reference plane A is 45°. Continuing with the example of the guide vane 120 near the left side of the air outlet 11, when the angle between the extending direction of the air outlet 1215 and the reference plane A is 45°, the deflection angle of the blade body 121 towards the left side of the air outlet 11 is also 45°. Therefore, the angle between the second airflow blown out by the air outlet 1215 and the perpendicular direction of the air outlet 11 is 0°, and the second airflow blows directly in front of the air outlet 11. Thus, when the air delivery angle of the adjusting assembly 100 is significantly deflected towards the same side as the air outlet 11, the airflow blown out by the air outlet 1215 is also deflected towards the same side of the air outlet 11.

[0246] Regarding the shape of the air outlet 1215 on the blade body 121, this embodiment does not impose specific limitations. The air outlet 1215 can have a relatively regular shape, as long as stress concentration is avoided. For example, the cross-sectional shape of the air outlet 1215 can be circular, elliptical, or regular polygonal. When the cross-sectional shape of the air outlet 1215 is a regular polygon, the cross-sectional shape of the air outlet 1215 can be, for example, a regular pentagon, a regular hexagon, or a regular octagon.

[0247] Air outlet holes 1215 of appropriate size can be machined on the blade body 121 according to its size. Taking a circular air outlet hole 1215 as an example, the diameter of the air outlet hole 1215 can be between 4mm and 9mm. In this way, the air outlet hole 1215 has a sufficient cross-sectional area to meet the air supply requirements and ensure that the air outlet holes 1215 on the blade body 121 have a certain air supply volume. Furthermore, the cross-sectional area of ​​the air outlet hole 1215 is not too large, and a sufficient number of air outlet holes 1215 can be made on the blade body 121 to avoid the air outlet holes 1215 affecting the structural strength and reliability of the blade body 121.

[0248] For example, the diameter of the air outlet 1215 can be 4.5mm, 5.0mm, 5.5mm, 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, etc.
