Description

[0001] The present application claims priority to the Chinese patent application No. 202411514814.7, filed on October 28, 2024, entitled "Air guide assembly and air treatment device", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of air treatment device, in particular to an air guide blade, an adjusting assembly, an air guide assembly and an air treatment device. BACKGROUND

[0003] The air treatment device, such as air conditioner, usually comprises an air outlet and an air guide plate arranged at the air outlet. The air guide plate is rotatably connected at the air outlet, and the air guide plate changes the air supply direction of the air outlet by changing the opening angle of the air guide plate relative to the air outlet.

[0004] However, the above-mentioned method of adjusting the air supply direction causes the air supply area of the air treatment device to be limited. SUMMARY

[0005] The present application provides an air guide blade, an adjusting assembly, an air guide assembly and an air treatment device. The air guide blade can make the air supply of the adjusting assembly more gentle, and can improve the comfort of the air treatment device. The air guide assembly can flexibly adjust the air supply angle of the air treatment device, and expand the air supply coverage area of the air treatment device.

[0006] The first aspect of the present application provides an air guide blade for being installed at an air outlet of an air treatment device. The air guide blade comprises a blade body, and a plurality of air outlet holes are distributed on the blade body, the air outlet holes penetrating through both sides of the blade body in the thickness direction; wherein the blade body comprises a first air guide side and a second air guide side arranged oppositely; when the blade body is in an open state, the first air guide side is located outside the air outlet, and the second air guide side is located inside the air outlet.

[0007] The air guide blade provided by the present application has a plurality of air outlet holes on the blade body of the air guide blade. When the air treatment device is in a working state, the airflow blown out of the air duct can flow outward through the air outlet holes on the blade body. In this way, part of the airflow flows outward along the air guide channel between adjacent air guide blades, and another part of the airflow flows outward through the air outlet holes on the blade body. The two parts of the airflow produce a butt joint effect, which can slow down the flow rate of the airflow flowing out of the air guide channel, avoid blowing out strong wind from the air outlet, and make the air supply effect of the air treatment device more gentle and improve the use comfort of the air treatment device.

[0008] In a possible implementation, the air outlet hole extends obliquely towards the same side of the air outlet as the air guide vane from a first surface of the vane body to a second surface of the vane body, wherein the first surface and the second surface are two side surfaces of the vane body in the thickness direction; when the air guide vane is oblique to the air outlet, the first surface faces the inner side of the air outlet and the second surface faces the outer side of the air outlet.

[0009] In this way, when the air guide vane is in the open state, the included angle between the extension direction of the air outlet hole and the side of the vane body close to the outer side of the air outlet in the air blowing direction of the adjustment assembly is an acute angle, and the air blowing direction of the air outlet hole tends to be the air guide direction of the vane body. The air flow blown out of the air outlet hole has little effect on the air blowing direction of the adjustment assembly as a whole, and the adjustment accuracy of the adjustment assembly in the air blowing direction and the air blowing area can be ensured.

[0010] In a possible implementation, the included angle between the extension direction of the air outlet hole and the reference plane is in the range of 30°-60°, wherein the reference plane is the normal projection plane of the vane body, and the reference plane passes through the central axis of the vane body.

[0011] By designing the included angle between the extension direction of the air outlet hole and the reference plane to be less than or equal to 60°, when the adjustment assembly is oblique to the same side of the air outlet, the air flow blown out of the air outlet hole will not be obviously directed to the other side of the air outlet, and the overall adjustment effect of the adjustment assembly is better. Moreover, the smaller the included angle between the extension direction of the air outlet hole and the reference plane, the more the air blowing direction of the air outlet hole tends to be close to the overall air blowing direction of the adjustment assembly.

[0012] In a possible implementation, the included angle between the extension direction of the air outlet hole and the reference plane is in the range of 40°-50°.

[0013] In this way, when the air blowing angle of the adjustment assembly is obviously deflected to the same side of the air outlet, the air flow blown out of the air outlet hole of the vane body is approximately blown to the front of the air outlet, or the air flow blown out of the air outlet hole is also deflected to the same side of the air outlet. In this way, the air outlet hole can avoid affecting the overall air blowing direction of the adjustment assembly. Moreover, the inclination of the air outlet hole is not too large, the air outlet hole occupies a moderate space in the planar direction of the vane body, and a sufficient number of air outlet holes can be machined on the vane body.

[0014] In a possible implementation, the included angle between the extension direction of the air outlet hole and the reference plane is 45°.

[0015] In a possible implementation, the cross-sectional shape of the air outlet hole includes at least one of a circle, an ellipse, and a regular polygon.

[0016] In a possible implementation, when the air outlet hole is a circular hole, the diameter of the air outlet hole is 4mm-9mm.

[0017] In a possible implementation, the air outlet holes are uniformly distributed on the surface of the blade body.

[0018] In this way, the blade body has sufficient opening area, and the air flow passing through the air outlet holes has sufficient air volume, so that the air flow can effectively function as soft wind. The pressure of the air flow on the blade body is uniformly distributed on the blade body, and the blade body is uniformly stressed, so that the reliability and service life of the blade body are improved.

[0019] In a possible implementation, the blade body comprises a first curved portion, the first curved portion is located on one side of the central axis of the blade body, and the first air guide side is the side of the first curved portion away from the central axis; and an angle is formed between the extension line of the first air guide side and the reference plane, the reference plane is the normal projection plane of the blade body and passes through the central axis.

[0020] In this way, the first curved portion 1216 causes the first air guide side 1212 to be inclined to one side of the blade body 121, and an angle is formed between the extension line of the first air guide side and the reference plane on which the blade body is located. The first air guide side can change the blowing angle of the adjustment assembly, so that the adjustment of the air guide assembly on the blowing area is more flexible, and the blowing coverage area of the air treatment equipment is expanded.

[0021] In a possible implementation, when the air guide blade is perpendicular to the plane on which the air outlet is located, the extension line of the first air guide side extends to the same side of the air outlet.

[0022] By extending the extension line of the first air guide side to the same side of the air outlet, when the air guide blade guides air to the same side of the air outlet, the first air guide side can further increase the blowing deflection angle of the air guide blade. In turn, the blowing area of the adjustment assembly is expanded.

[0023] In a possible implementation, the angle between the extension line of the first air guide side and the reference plane is in the range of 5°-45°.

[0024] In this way, the air guide blade only needs to rotate within a small angle range, so that the air guide blade has a blowing area within a large angle range. Moreover, the angle between the extension line of the first air guide side and the reference plane is not too large, the bending degree of the first curved portion is appropriate, and the air guide blade does not hinder the flow of air. The overall air resistance of the adjustment assembly is small, and the blowing volume of the air treatment equipment is not affected.

[0025] In a possible implementation, the blade body further comprises a second curved portion, the second curved portion is located on the other side of the central axis of the blade body; the side of the second curved portion away from the central axis is a second air guide side, and the extension line of the second air guide side extends to the other side of the reference plane.

[0026] In this way, when the air guide blade capable of rotating 360° is rotated to the second air guide side of the blade body being located outside the air outlet, the second air guide side also inclines to the left side of the air outlet, as the first air guide side does when being located outside the air outlet. The air guide blade can also be rotated to the second air guide side being located outside the air outlet, and the air guide blade guides the airflow blown out of the air outlet by the second air guide side, and the air guide blade increases the air supply deflection angle by the second air guide side.

[0027] In a possible implementation, the bending shape of the second bending part is consistent with the bending shape of the first bending part, and the blade body has a central symmetry structure.

[0028] In this way, when either the first air guide side or the second air guide side is located outside the air outlet, the air guide blade has the same air supply deflection angle when the blade body is deflected to a certain angle. In addition, the air guide blade is balanced in force, and has better stability and higher reliability. In addition, since the air guide blade has a symmetrical structure, the two sides of the air guide blade do not need to be distinguished during installation, the installation efficiency of the air guide blade is higher, and the appearance effect of the adjustment assembly is better.

[0029] In a possible implementation, the blade body is a flat plate.

[0030] In a possible implementation, the air guide blade further comprises a rotating shaft, the rotating shaft is connected to the blade body, and the rotating shaft extends along the central axis of the blade body, and the blade body rotates around the rotating shaft.

[0031] In this way, the air guide blade can be rotatably connected to the bearing plate by the rotating shaft, and the air supply direction of the adjustment assembly can be changed by rotating the blade body around the rotating shaft. In addition, by arranging the rotating shaft on the central axis of the blade body, the air guide blade has better stability and higher reliability, and is also conducive to the layout design of the air guide blade, and the air guide blade requires the least space.

[0032] The second aspect of the present application provides an adjustment assembly installed at an air outlet of an air handling device, the adjustment assembly comprising: a bearing plate extending along the length direction of the air outlet; a plurality of air guide blades, each air guide blade being movably connected to the bearing plate, and each air guide blade being arranged in sequence along the plate surface of the bearing plate; wherein at least part of the air guide blades are the air guide blades as described above.

[0033] The adjustment assembly provided by the present application adjusts the air supply angle of the adjustment assembly by arranging each air guide blade in sequence on the plate surface of the bearing plate, and movably connecting each air guide blade to the bearing plate, so as to change the included angle between each air guide blade and a certain direction on the plate surface of the bearing plate.

[0034] The adjusting assembly has all the technical effects of the air guide vane, and thus, details are not repeated here.

[0035] The third aspect of the present application provides an air guide assembly installed at an air outlet of an air handling device, comprising: an adjusting assembly as described above; and a first driving assembly connected to the adjusting assembly and driving each air guide vane in the adjusting assembly to change position relative to the bearing plate.

[0036] The air guide assembly provided by the present application drives each air guide vane to move by the first driving assembly to change the included angle between each air guide vane and a certain direction on the surface of the bearing plate, thereby adjusting the air supply angle of the adjusting assembly.

[0037] The air guide assembly has all the technical effects of the air guide vane, and thus, details are not repeated here.

[0038] In a possible implementation, the first driving assembly also drives the bearing plate in the adjusting assembly to move.

[0039] In this way, the first driving assembly drives each air guide vane on the bearing plate to move and also drives the air guide vane to move together with the bearing plate. In this way, the air supply angle of the air guide assembly can be flexibly adjusted, the air supply area of the air guide assembly is expanded, the air supply coverage area of the air guide assembly is larger, and large-area area air supply can be achieved. The indoor temperature can be adjusted more quickly, the temperature uniformity in the room is improved, and the comfort in the room is improved.

[0040] In a possible implementation, the air guide assembly comprises at least two adjusting assemblies, and each adjusting assembly is arranged at intervals along the length direction of the air outlet.

[0041] In this way, different adjusting assemblies can supply air to different areas, the air supply area of the air guide assembly is expanded, and the air supply coverage area of the air handling device is expanded. Furthermore, the temperature of the entire space in the room can be more uniformly adjusted, the temperature difference in the room is reduced, the discomfort caused by strong wind in a local area is reduced, and the overall comfort in the room is improved. Moreover, the air handling device can complete the refrigeration target or the heating target in a shorter time, and the energy efficiency is higher.

[0042] In a possible implementation, the air guide assembly further comprises at least one second driving assembly, the second driving assembly is connected between two adjacent adjusting assemblies, and the second driving assembly drives the bearing plates in the two adjusting assemblies to move at the same time.

[0043] By setting the first driving assembly to drive the guide vane and the second driving assembly to drive the bearing plate, the first driving assembly and the second driving assembly respectively drive one moving object, the driving mode is relatively simple, the structural design of the first driving assembly and the second driving assembly can be relatively simplified, and the design cost of the two can be reduced. Moreover, the first driving assembly and the second driving assembly do not affect each other, and the operation reliability of the guide vane assembly is higher.

[0044] The fourth aspect of the present application provides an air treatment device comprising a device body and a guide vane assembly as described above.

[0045] The air treatment device provided by the present application has all the technical effects of the guide vane assembly, and details are not repeated here. BRIEF DESCRIPTION OF DRAWINGS

[0068] As described in the background, conventional air conditioning devices are provided with swingable air guide plates in the air duct to adjust the air supply angle. For example, horizontally arranged air guide plates swing up and down to achieve up and down air sweeping, and vertically arranged air guide plates swing left and right to achieve left and right air sweeping. The swing angle of all air guide plates is uniformly regulated by connecting rods, so as to adjust the overall air supply area of the air conditioning device.

[0069] However, the above-mentioned method of adjusting the air supply area is positively correlated with the area size of the air outlet. This will result in a limited air supply area of the air conditioning device, a small air supply coverage area, and an inability to achieve large-area air supply.

[0070] 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, each of which is provided with multiple air guide vanes. The air delivery area of ​​the air handling device is adjusted by the oscillation of the air guide vanes. By designing the air guide vanes, several air outlet holes are opened on the vane body. When the air handling device is in operation, the airflow blown out of the duct can flow outward through the air outlet holes on the vane body. In this way, part of the airflow flows outward along the air guide channel between adjacent air guide vanes, and another part of the airflow flows outward through the air outlet holes on the vane body. The opposing effect of these two airflows can slow down the airflow velocity from the air guide channel, avoid strong winds blowing out of the air outlet, make the air delivery effect of the air handling device gentler, and improve the user comfort of the air handling device.

[0071] 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.

[0072] 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.

[0073] The following explanation uses a wall-mounted air conditioner as an example of an air handling unit.

[0074] Figure 1 This is a schematic diagram of an air handling device provided in an embodiment of this application. (Refer to...) Figure 1 As 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.

[0075] The air outlet 11 of the device body 10 is provided with an air guide assembly 20. The air guide assembly 20 is used to adjust the air supply direction and air supply area of the air treatment device 1, so as to realize flexible air supply of the air treatment device 1.

[0076] Figure 2 A perspective view of the air guide assembly from one perspective.

[0077] Figure 3 For Figure 2 A perspective view of the air guide assembly from another perspective.

[0078] Referring to Figure 2 As shown in the figure, the air guide assembly 20 comprises an adjusting assembly 100, which is arranged in the air duct of the device body 10. The air duct has a mounting base for the adjusting assembly 100, and the adjusting assembly 100 can be mounted on the mounting base. In addition, the adjusting assembly 100 can be located at the air outlet 11 of the device body 10. For example, the adjusting assembly 100 can cover most of the area of the air outlet 11, so as to adjust the air supply direction and air supply area of the device body 10 through the adjusting assembly 100.

[0079] For the convenience of description, the embodiment defines a basic air duct wall 12 (see Figure 1 As shown in the figure), which is, for example, a side wall surface of the air duct close to the wall, and the adjusting assembly 100 can be mounted on the basic air duct wall 12. The adjusting assembly 100 can be directly mounted on the basic air duct wall 12, or can be mounted on the basic air duct wall 12 through other support components.

[0080] The adjusting assembly 100 can comprise a bearing plate 110 and a plurality of air guide blades 120. The bearing plate 110 can be mounted on the basic air duct wall 12, and the plate surface of the bearing plate 110 can be parallel to the wall surface of the basic air duct wall 12, for example. In addition, the bearing plate 110 can extend along the length direction of the air outlet 11, so as to realize that the adjusting assembly 100 can cover the air outlet 11. The air guide blades 120 are arranged in sequence along the plate surface of the bearing plate 110, and each air guide blade 120 is movably connected to the bearing plate 110.

[0081] Among them, the bearing plate 110 is close to the basic air duct wall 12, so as to facilitate mounting the adjusting assembly 100 on the basic air duct wall 12 through the bearing plate 110. The air guide blades 120 can be located on the side plate surface of the bearing plate 110 away from the basic air duct wall 12. The air guide blades 120 are directed towards the air outlet 11, and the air guide blades 120 extend towards the air outlet 11. In this way, the airflow in the air duct can be blown out from the air outlet 11 after passing through the air guide blades 120, so as to guide the airflow through the air guide blades 120.

[0082] Referring to Figure 3As shown, the air guide assembly 20 further comprises a driving mechanism 200 connected with the adjusting assembly 100. The driving mechanism 200 drives the adjusting assembly 100 to move, so as to realize the adjustment of the air supply direction and the air supply area by the adjusting assembly 100.

[0083] The driving mechanism 200 is used at least for driving the air guide blades 120 of the adjusting assembly 100 to move, so as to change the positions of the air guide blades 120 relative to the bearing plate 110. The included angle between the air guide blades 120 and a certain direction on the plate surface of the bearing plate 110 changes, and the air guide blades 120 are collectively deflected to one side of the air outlet 11, so as to adjust the air supply angle of the adjusting assembly 100.

[0084] On this basis, the bearing plate 110 can be movably connected to the base air duct wall 12, and the driving mechanism 200 can also be used for driving the bearing plate to move. The driving mechanism 200 drives the bearing plate 110 to move, so as to change the position of the bearing plate 110 relative to the air outlet 11, and the distance between the bearing plate 110 and the base air duct wall 12 changes.

[0085] The air guide blades 120 on the bearing plate 110 move together with the bearing plate 110, so as to change the positions of the air guide blades 120 relative to the air outlet 11. The bearing plate 110 can move towards the outside of the air outlet 11, and part or all of the air guide blades 120 on the bearing plate 110 can extend to the outside of the air outlet 11. In this way, the interference between the air guide blades 120 and the air duct is obviously improved, the deflection angle limitation of the air duct on the air guide blades 120 can be weakened or even eliminated, and the deflection angle range of the air guide blades 120 can be further expanded.

[0086] In this way, the driving mechanism 200 drives the air guide blades 120 on the bearing plate 110 to move, and also drives the air guide blades 120 to move together with the bearing plate 110, so that the driving mode of the driving mechanism 200 on the adjusting assembly 100 is more flexible. In this way, the air supply angle of the air guide assembly 20 can be flexibly adjusted, the air supply area of the air guide assembly 20 is expanded, the air supply coverage area of the air guide assembly 20 is larger, and large-area area air supply can be realized. The indoor temperature can be adjusted more quickly, the temperature uniformity in the room is improved, and the comfort in the room is improved.

[0087] Moreover, the air guide assembly 20 can direct air to more areas, and the air guide assembly 20 can improve the adjustment accuracy of the air directing area. Furthermore, the air directing angle of the air guide assembly 20 can be adjusted by the driving mechanism 200, so that the air directing area of the air guide assembly 20 can avoid the user's activity area, and the user's body discomfort or health problems caused by the direct blowing of cold air can be avoided. The air directing angle of the air guide assembly 20 can be continuously changed by the driving mechanism 200, so that the air guide assembly 20 can avoid blowing to a certain area for a long time, and the uniformity of the overall indoor temperature can be improved.

[0088] In this embodiment, the driving mechanism 200 drives the bearing plate 110 to move in a swinging manner, and the bearing plate 110 can swing (or be considered as rotating) on the base air duct wall 12 about the rotation axis of the bearing plate 110. Furthermore, the position of the bearing plate 110 relative to the air outlet 11 is changed, and the included angle of the bearing plate 110 relative to the plane direction of the air outlet 11 is changed. Taking one end of the bearing plate 110 away from the rotation axis of the bearing plate 110 as a reference, the end of the bearing plate 110 swings towards the air outlet 11 (for example, the end of the bearing plate 110 extends out of the air outlet 11), or the end of the bearing plate 110 swings away from the air outlet 11 (for example, the end of the bearing plate 110 is withdrawn into the air outlet 11).

[0089] In this way, the driving mechanism 200 not only drives the air guide blade 120 to swing relative to the bearing plate 110, changes the included angle between the air guide blade 120 and the certain direction of the plate surface of the bearing plate 110, and adjusts the air directing direction by swinging the air guide blade 120 itself. Moreover, the driving mechanism 200 also drives the bearing plate 110 to swing relative to the air outlet 11, and the deflection angle of the bearing plate 110 is superimposed on the deflection angle of the air guide blade 120, so as to adjust the air directing direction. In this way, the air directing angle range of the adjustment assembly 100 is increased, the air directing area of the adjustment assembly 100 is expanded, and the air directing coverage area of the air handling device 1 is larger.

[0090] Of course, in other embodiments, the driving mechanism 200 can also drive the bearing plate 110 to move in a translation manner, the length direction of the bearing plate 110 always coincides with the length direction of the air outlet 11, and the bearing plate 110 translates on the base air duct wall 12 along the width direction of the bearing plate 110. Furthermore, the position of the bearing plate 110 relative to the air outlet 11 is changed. For example, the bearing plate 110 moves from the position accommodated in the air duct to the direction of the air outlet 11, for example, the bearing plate 110 moves to the plane where the air outlet 11 is located, or even the bearing plate 110 extends out of the air outlet 11. Or, the bearing plate 110 moves from the position located on the plane where the air outlet 11 is located or outside the air outlet 11 to the air duct, so as to withdraw the bearing plate 110 into the air duct.

[0091] In this way, the driving mechanism 200 can drive the carrier plate 110 to move towards the air outlet 11, so that the air guide blades 120 on the carrier plate 110 are closer to the air outlet 11, or even extend out of the air outlet 11. The swing range of the air guide blades 120 can be increased without being limited by the air duct, and the deflection angle range of the air guide blades 120 can be increased. In turn, the air supply area of the adjustment assembly 100 is expanded, and the air supply coverage area of the air handling equipment 1 is expanded. When the deflection angle of the air guide blades 120 is too large, and the air supply area of the air guide assembly 20 is towards the edge of the air outlet 11, the air supply of the air guide assembly 20 can be prevented from being hindered by the air duct, and the air flow can be prevented from being disturbed.

[0092] The following are all examples of driving the carrier plate 110 to swing on the base air duct wall 12 by the driving mechanism 200.

[0093] Referring to Figure 2 Or Figure 3 As for the air guide mode of the air guide assembly 20, as an embodiment, the air guide assembly 20 can be used to realize left-right air sweeping. At this time, each air guide blade 120 mounted on the carrier plate 110 can be sequentially and spacedly arranged along the length direction of the carrier plate 110, and the air flow blown in the air duct is guided through the air guide channel formed between the left-right adjacent two air guide blades 120. Each air guide blade 120 can swing towards both ends of the length direction of the air outlet 11, or it can be said that each air guide blade 120 swings towards both ends of the left-right direction of the air outlet 11, so as to guide the air flow to the left side or the right side of the air outlet 11.

[0094] For example, each air guide blade 120 can be rotatably connected to the carrier plate 110. The rotation axis of each air guide blade 120 can be perpendicular to the plate surface of the carrier plate 110, and the blade surface of each air guide blade 120 can also be perpendicular to the plate surface of the carrier plate 110. The driving mechanism 200 can drive each air guide blade 120 to rotate along its rotation axis, so as to realize the overall and unified swing of all air guide blades 120 towards both ends of the left-right direction of the air outlet 11.

[0095] In other embodiments, the air guide assembly 20 can also be used to realize up-down air sweeping. At this time, each air guide blade 120 mounted on the carrier plate 110 can be sequentially and spacedly arranged along the width direction of the carrier plate 110, and the air flow blown in the air duct is guided through the air guide channel formed between the up-down adjacent two air guide blades 120. Each air guide blade 120 can swing towards both ends of the height direction (or width direction) of the air outlet 11, or it can be said that each air guide blade 120 swings towards both ends of the up-down direction of the air outlet 11, so as to guide the air flow to the upper side or the lower side of the air outlet 11.

[0096] For example, the wind guide blades 120 can be rotatably connected to the carrier plate 110. The rotation axes of the wind guide blades 120 can be parallel to the plate surface of the carrier plate 110. The wind guide blades 120 can be connected to the carrier plate 110 through supports. For example, the two ends of the wind guide blades 120 in the extending direction thereof are the rotation axes thereof. The rotation axes of the two ends of the wind guide blades 120 are rotatably connected to the carrier plate 110 through supports. The wind guide blades 120 and the plate surface of the carrier plate 110 have a gap therebetween. The driving mechanism 200 can drive the wind guide blades 120 to rotate along the rotation axes thereof, so as to realize the swinging of all the wind guide blades 120 as a whole to the upper and lower ends of the air outlet 11.

[0097] In other embodiments, the air guide assembly 20 can also be used to realize the wind sweeping in different directions. For example, the air guide assembly 20 can realize the wind sweeping to the left and right and the wind sweeping to the upper and lower. That is, the wind guide blades 120 can swing to the left and right ends of the air outlet 11 in the length direction thereof, and the wind guide blades 120 can also swing to the upper and lower ends of the air outlet 11 in the height direction thereof.

[0098] For example, the wind guide blades 120 can be rotatably connected to the carrier plate 110. Since the air guide assembly 20 can realize the wind sweeping in different directions, the wind guide blades 120 can have rotation axes in different directions. For example, the wind guide blades 120 can have rotation axes perpendicular to the plate surface of the carrier plate 110, and the wind guide blades 120 can also have rotation axes parallel to the plate surface of the carrier plate 110. All the wind guide blades 120 are installed on the carrier plate 110 in the form of air guide groups. Each air guide group includes a plurality of wind guide blades 120. Each air guide group is rotatably connected to the carrier plate 110 through the rotation axes perpendicular to the plate surface of the carrier plate 110. Each wind guide blade 120 in each air guide group is provided with the rotation axis parallel to the plate surface of the carrier plate 110.

[0099] The following is described by taking the air guide assembly 20 for realizing the wind sweeping to the left and right as an example. The wind guide blades 120 are sequentially arranged along the length direction of the carrier plate 110. The wind guide blades 120 are rotatably connected to the carrier plate 110. The rotation axes of the wind guide blades 120 are perpendicular to the plate surface of the carrier plate 110.

[0100] Continuing to refer to Figure 2 Or Figure 3 As to the number of the adjusting assemblies 100 in the air guide assembly 20, as an embodiment, the number of the adjusting assemblies 100 can be two. The two adjusting assemblies 100 can be arranged in the length direction of the air outlet 11. Under the driving of the driving mechanism 200, the wind guide blades 120 of the two adjusting assemblies 100 can be deflected relative to the carrier plates 110 thereof. The carrier plates 110 of the two adjusting assemblies 100 can also be deflected relative to the air outlet 11.

[0101] By arranging two adjusting assemblies 100 along the length direction of the air outlet 11, the two adjusting assemblies 100 can respectively send air to different areas. The two adjusting assemblies 100 respectively have different air sending areas, which can expand the air sending area of the air guide assembly 20 and expand the air sending coverage of the air handling device 1.

[0102] For example, in the paper surface direction in the figure, the adjusting assembly 100 on the left is driven by the driving mechanism 200 to deflect the air guide blade 120 of the adjusting assembly 100 to the left, and the adjusting assembly 100 on the right is driven by the driving mechanism 200 to deflect the air guide blade 120 of the adjusting assembly 100 to the right, so that the air sending area of the air guide assembly 20 as a whole is expanded. On this basis, if the driving mechanism 200 drives the bearing plate 110 in the adjusting assembly 100 on the left to deflect to the left and the bearing plate 110 in the adjusting assembly 100 on the right to deflect to the right, the air sending area of the air guide assembly 20 as a whole will be further expanded.

[0103] In this way, the air conditioner has a larger air sending coverage, can more uniformly adjust the temperature of the entire indoor space, reduces the temperature difference in the indoor space, and improves the overall comfort of the indoor space. In addition, the larger air sending coverage also enables the air conditioner to reach the set temperature target faster, so that the air conditioner can complete the cooling target or heating target in a shorter time, and the air conditioner has higher energy efficiency. In addition, the larger air sending coverage enables the air flow distribution area of the air flow blown by the air conditioner to be wider and the air flow speed to be more gentle, which can reduce the discomfort caused by strong wind in a local area, provide a soft air sending effect, and enable the user to have a more natural and comfortable feeling in the air conditioner environment.

[0104] As another embodiment, the air guide assembly 20 can also include only one adjusting assembly 100. Under the driving of the driving mechanism 200, the air guide blade 120 of the adjusting assembly 100 can deflect relative to the bearing plate 110, and the bearing plate 110 can also deflect relative to the air outlet 11. Thus, the one adjusting assembly 100 also has a large enough air sending area, which can meet the requirements of a general indoor space.

[0105] For example, when the air handling device 1 is applied in a residential living space, the indoor space is small, and only one adjusting assembly 100 can also meet the requirements of the indoor space. Alternatively, when the deflection angle range of the air guide blade 120 of the adjusting assembly 100 is large, the deflection angle range of the bearing plate 110 is also large, and the air guide blade 120 and the bearing plate 110 are superimposed to make the adjusting assembly 100 have a large air sending area, one adjusting assembly 100 can also meet the air sending requirements of a larger space, and thus the air guide assembly 20 can include only one adjusting assembly 100.

[0106] Of course, in other embodiments, the air guide assembly 20 can also include more than three adjusting assemblies 100, each adjusting assembly 100 being arranged along the length direction of the air outlet 11 in sequence. The driving mechanism 200 drives the air guide blades 120 of each adjusting assembly 100 to deflect relative to the respective carrier plates 110, and also drives the carrier plates 110 of each adjusting assembly 100 to deflect relative to the air outlet 11.

[0107] For example, when the air handling device 1 has a large volume and has a long air outlet 11, a plurality of adjusting assemblies 100 can be arranged along the length direction of the air outlet 11 in sequence, and each adjusting assembly 100 maintains a suitable length to meet the requirements of good stability and reliability of the adjusting assembly 100. Alternatively, when the air handling device 1 is applied in a large space such as an office or a factory, the air guide assembly 20 can have a larger air supply coverage area by arranging a plurality of adjusting assemblies 100 to meet the air supply requirements of the large space.

[0108] Referring to Figure 3 To achieve the driving mechanism 200 that can drive each air guide blade in the adjusting assembly to deflect relative to the carrier plate and also drive the carrier plate to deflect relative to the air outlet 11, the driving mechanism 200 can include a first driving assembly 210 connected to the adjusting assembly, and the first driving assembly 210 is used to at least drive each air guide blade in the adjusting assembly to deflect relative to the carrier plate.

[0109] The first driving assembly 210 and the adjusting assembly can be arranged one-to-one, and when the air guide assembly includes more than two adjusting assemblies, the driving mechanism 200 can also include more than two first driving assemblies 210, each first driving assembly 210 being connected to each adjusting assembly. The corresponding adjusting assembly is driven to move by the first driving assembly 210.

[0110] Referring to Figure 3 In some embodiments, when the air guide assembly includes more than two adjusting assemblies, the driving mechanism 200 can also include at least one second driving assembly 220, and the second driving assembly 220 can be connected between two adjacent adjusting assemblies. At this time, the first driving assembly 210 can only be used to drive each air guide blade to deflect relative to the carrier plate, and the carrier plates in the two adjusting assemblies connected on both sides thereof are driven to move by the second driving assembly 220.

[0111] When the air guide assembly includes two adjusting assemblies, the driving mechanism 200 can only include one second driving assembly 220, and the second driving assembly 220 is connected between the two adjusting assemblies, and the second driving assembly 220 can drive the carrier plates of the two adjusting assemblies to move relative to each other.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] When the first driving assembly 210 drives the guide vanes and the carrier plates simultaneously, as an embodiment, the first driving assembly 210 can be provided with two driving motors 201, one of which is connected to the guide vanes and the other of which is connected to the carrier plates. In this way, the two driving motors 201 do not affect each other, and even if one of them fails to work, the other one can still work, and the probability that the guide vanes and the carrier plates cannot move is low, and the operation reliability of the adjusting assembly is higher.

[0118] When the first driving assembly 210 drives the guide vanes and the carrier plates simultaneously, as another embodiment, the first driving assembly 210 can also be provided with only one driving motor 201. The output shaft of the driving motor 201 can be directly connected to the guide vanes, and the output shaft of the driving motor 201 is connected to the carrier plates through a transmission structure, so as to drive the guide vanes and the carrier plates to move simultaneously by one driving motor 201. For example, the transmission structure can be a gear set, the driving motor 201 directly drives the guide vanes to rotate, and the driving motor 201 drives the carrier plates to swing through the gear set.

[0119] As to the structural design of the second driving assembly 220, in combination with the drawings shown in Figure 2 and Figure 3 , the second driving assembly 220 can include a driving motor 201 and a transmission member 221, the driving motor 201 is in transmission connection with the transmission member 221, and the transmission member 221 is connected between the carrier plates of two adjacent adjusting assemblies. The driving motor 201 drives the transmission member 221 to move, and the transmission member 221 drives the two carrier plates to move relatively.

[0120] For example, the transmission member 221 can include a push-pull rod 2211 and two connecting rods 2212, the driving motor 201 is in transmission connection with 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 of the two connecting rods 2212 is connected to the two carrier plates respectively. The driving motor 201 drives the push-pull rod 2211 to move in the plane direction of the plate surface of the carrier plate, so that the push-pull rod 2211 drives the two connecting rods 2212 to move relatively, and in turn, drives the two carrier plates to swing relatively.

[0121] Figure 4 A disassembled structural view of the adjusting assembly provided in the embodiments of the present application is shown. Referring to Figure 4 , in order to realize that the first driving assembly 210 drives all the guide vanes on the carrier plates to swing, the adjusting assembly can also be provided with a linkage member 130, and all the guide vanes are connected to the linkage member 130. When the first driving assembly 210 operates, the linkage member 130 can be driven to move, so as to drive all the guide vanes to swing synchronously through the linkage member 130.

[0122] The first driving assembly 210 can be connected with one of the guide vanes on the bearing plate, for example, the first driving assembly 210 is connected with the guide vane at one end of the bearing plate in the length direction. The first driving assembly 210 drives the guide vane to rotate, and the guide vane drives the linkage 130 connected therewith to move. In turn, all the guide vanes are driven to swing synchronously by the linkage 130.

[0123] Alternatively, the first driving assembly 210 can also be connected with the linkage 130, for example, the first driving assembly 210 is connected at the part of the linkage 130 between two guide vanes. The first driving assembly 210 drives the linkage 130 to move, and the linkage 130 drives all the guide vanes to swing synchronously.

[0124] Continuing to refer to Figure 4 , the linkage 130 can be arranged in the bearing plate. In this way, the linkage 130 is connected with all the guide vanes. Moreover, the linkage 130 is shielded in the bearing plate, so that the appearance of the adjustment assembly is more simple. In addition, the linkage 130 does not occupy additional separate space, and has no influence on the volume of the adjustment assembly, which is beneficial to the thinning of the adjustment assembly.

[0125] In order to install the linkage 130 in the bearing plate 110 and facilitate the linkage 130 to be connected with the guide vanes, the bearing plate 110 can be divided into a face plate 111 and a bottom plate 112, the face plate 111 and the bottom plate 112 jointly enclose a receiving cavity, and the linkage 130 is arranged in the receiving cavity. All the guide vanes can be installed on the face plate 111, and the first driving assembly 210 can be installed on the bottom plate 112, and the first driving assembly 210 passes through the bottom plate 112 to be connected with the guide vanes or the linkage 130.

[0126] As shown in Figure 4 , as an example, the linkage 130 can be a connecting rod 130a, the connecting rod 130a can extend along the extension direction of the bearing plate 110, and the connecting rod 130a is connected with all the guide vanes 120. The driving motor 201 of the first driving 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 reciprocation of the connecting rod 130a, all the guide vanes 120 are driven to swing. Alternatively, the output shaft of the driving motor 201 is connected with the connecting rod 130a, and the driving motor 201 is rotated to drive the connecting rod 130a to reciprocate with a small swing amplitude, thereby driving all the guide vanes 120 to swing.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] The thickness of the blade body 121 can be between 2mm and 3mm. In this way, the blade body 121 has a certain thickness, which meets the processability requirements of the blade body 121 and can ensure the required structural strength of the blade body 121. At the same time, the thickness of the blade body 121 is relatively small, the space occupied by the blade body 121 is small, and there is enough space between adjacent blades, so that the air flow in the air duct can be smoothly guided out, avoiding affecting the air outlet of the air treatment equipment 1.

[0132] 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.

[0133] When the air guide blade 120 is rotationally connected to the bearing plate 110, the air guide blade 120 can further include a rotating shaft 122. The rotating shaft 122 is connected to the blade body 121, and the rotating shaft 122 can be integrally formed on the blade body 121 to form an integrally formed air guide blade 120. The rotating shaft 122 can be connected to one end of the blade body 121 facing the bearing plate 110, and the rotating shaft 122 is rotationally connected to the bearing plate 110, and the blade body 121 rotates around the rotating shaft 122.

[0134] For example, the rotating shaft 122 can be located on the central axis of the blade body 121. In this way, the air guide blade 120 has good force balance, and the stability and reliability of the air guide blade 120 during rotation are better. Moreover, the width of the blade body 121 on both sides of the central axis remains the same, which is more conducive to the layout and installation of the air guide blade 120, and the spacing between adjacent blades can be designed according to the width of the blade body 121, so that each air guide blade 120 is uniformly spaced. In addition, the air guide blade 120 can also be better applied in a 360° rotation scenario, the movement range of the air guide blade 120 is the smallest, and the required movement space of the air guide blade 120 is also the smallest, which can reduce the occupied space of the air guide assembly 20, and is conducive to the miniaturization of the air treatment equipment 1.

[0135] For example, the rotating shaft 122 can include a disc structure (not shown in the figure), and the bearing plate 110 can be provided with a mounting groove (not shown in the figure), and the disc structure can rotate in the mounting groove to realize the rotation of the air guide blade 120 on the bearing plate 110. The disc structure can be completely accommodated in the mounting groove. For example, the disc structure is flush with the front surface of the bearing plate 110 (the side surface of the bearing plate 110 facing the blade body 121). In this way, the disc structure does not protrude on the surface of the bearing plate 110, which helps to reduce the air resistance of the adjustment assembly 100. Moreover, the flatness of the adjustment assembly 100 is better, and it is more beautiful.

[0136] Figure 6For Figure 5 Fig. 6 is a structural schematic view of the air guide vane in the adjusting assembly in Fig. 5. In Fig. 6, Figure 6 Fig. 6 shows the structure of the part where one of the air guide vanes 120 on the adjusting assembly 100 is located.

[0137] Referring to Fig. 6, the vane body 121 of the air guide vane 120 can be provided with a plurality of air outlet holes 1211, which penetrate through the two side surfaces of the vane body 121 in the thickness direction. By providing the air outlet holes 1211 on the vane body 121, when the air handling device 1 is in the working state, the airflow blown in the air duct can flow outward through the air outlet holes 1211 on the vane body 121. Figure 6 Specifically, when the air guide vane 120 is in the open state, the air guide vane 120 has an included angle with the plane where the air outlet 11 is located, and the air guide channel is formed between the adjacent air guide vanes 120. At this time, the airflow blown in the air duct will flow outward along the air guide channel, and a part of the airflow can flow outward through the air outlet holes 1211 on the vane body 121. In this way, the air supply effect of the air handling device 1 is improved by using the air outlet holes 1211 on the vane body 121.

[0138] When the air handling device 1 blows air outward through the adjusting assembly 100, in addition to the first airflow flowing outward along the air guide channel, the second airflow flowing outward through the air outlet holes 1211 will also be generated, and the flow direction of the second airflow is different from that of the first airflow. Under the counterflow action of the second airflow on the first airflow, the flow rate of the first airflow can be slowed down, avoiding blowing strong wind from the air outlet 11, and the air supply effect of the air handling device 1 can be more gentle, improving the use comfort of the air handling device 1.

[0139] It should be noted that the air outlet holes 1211 provided on the vane body 121 have a small aperture, and the airflow in the air duct will still preferentially flow outward through the air guide channel between the adjacent air guide vanes 120. Thus, most of the airflow in the air duct will flow out through the air guide channel between the adjacent air guide vanes 120, and only a small part of the airflow will flow out through the air outlet holes 1211. This small part of the airflow flowing through the air outlet holes 1211 can have a good counterflow mixing effect, which can weaken the air supply flow rate. At the same time, it will not have too much impact on the air supply direction and air supply area of the adjusting assembly 100 as a whole, and the air supply adjusting effect of the adjusting assembly 100 can be ensured.

[0140]

[0141] ​When the guide vane 120 is in the closed state, the guide vane 120 is parallel to the plane where the air outlet 11 is located as a whole, and each guide vane 120 of the adjusting assembly 100 can be located on the same straight line, and only a small mounting gap exists between adjacent guide vanes 120. At this time, the airflow in the air duct is basically flowed outward through the air outlet hole 1211 on the vane body 121. Since the air outlet hole 1211 has a small aperture and the vane body 121 has a limited opening area, the flow rate of the airflow flowed out of the air outlet hole 1211 of each guide vane 120 is small, and the air supply amount of the air handling device 1 is small and the air speed is low.

[0142] For example, when the air handling device 1 is in heating, the guide vane 120 can be in the closed state, and only the air outlet hole 1211 on each guide vane 120 is used to transport hot air outward. Since the flow rate of the hot air 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 outlet hole 1211 on the vane body 121. Moreover, by outputting the hot air outward only through the air outlet hole 1211 on the vane body 121, the flow rate of the hot air can be limited, the indoor space can be maintained at a suitable temperature, and the energy consumption of the air handling device 1 can be reduced.

[0143] The plurality of air outlet holes 1211 can be uniformly distributed on the surface of the vane body 121. In this way, the vane plate body can have sufficient opening area, the second airflow flowed out of the air outlet hole 1211 can have sufficient air volume, and the second airflow can effectively reduce the flow rate of the first airflow, so that the air handling device 1 can supply air gently. Moreover, since the air outlet holes 1211 are uniformly distributed on each region of the vane body 121, the pressure of the second airflow on the vane body 121 is uniformly distributed on the vane body 121, the stress uniformity of the vane body 121 is good, and the reliability and service life of the vane body 121 can be improved.

[0144] For example, the air outlet holes 1211 can be arrayed on the surface of the vane body 121. Along the height direction of the vane body 121 (for example, the width direction of the air outlet hole 1211), a plurality of rows of air outlet holes 1211 are arranged in sequence, and each row of air outlet holes 1211 includes a plurality of air outlet holes 1211 arranged in sequence along the width direction of the vane body 121. Adjacent two rows of air outlet holes 1211 can be arranged staggered, and each air outlet hole 1211 in one row can correspond to the adjacent two air outlet holes 1211 in another row.

[0145] The area of the air outlet holes 1211 on the blade body 121 can account for 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 sufficient opening area to ensure the flow area of the blade body 121 itself, and the airflow flowing outwards through the air outlet holes 1211 of the blade body 121 reaches a certain flow rate, which can achieve an effective air supply softening effect.

[0146] For example, the opening rate of the blade body 121 can be between 50%-60%. In this way, more than half of the area of the blade body 121 is occupied by the air outlet holes 1211, and the air supply flow rate of the air supply through the air outlet holes 1211 of the blade body 121 is sufficient. Also, it avoids the opening rate of the blade body 121 being too large, which can meet the opening processing requirements of the blade body 121 and ensure the structural strength and reliability of the blade body 121.

[0147] Figure 7 For Figure 6 the cross-sectional view of the guide vane. Referring to Figure 7 , the guide vane 120 is cut in the middle region of a row of air outlet holes 1211 along the width direction of the guide vane 120. On the basis of the air outlet holes 1211 formed on the blade body 121, the extension direction of the air outlet holes 1211 is designed in this embodiment. The air outlet holes 1211 do not extend along the thickness direction of the blade body 121, but are designed to be inclined.

[0148] For ease of description, the opposite sides of the blade body 121 of the guide vane 120 are defined as a first guide side 1212 and a second guide side 1213 in this embodiment, and the first guide side 1212 and the second guide side 1213 are located on both sides of the central axis of the blade body 121. When the air handling equipment 1 is in a working state and the guide vane 120 is in an open air outlet 11 state, the first guide side 1212 of the blade body 121 is located at the outer position of the air outlet 11, and the second guide side 1213 of the blade body is located at the inner position of the air outlet 11.

[0149] Also, the two side surfaces of the thickness direction of the blade body 121 are defined as a first surface 1214 and a second surface 1215 in this embodiment. When the guide vane 120 is in an open state and the guide vane 120 is inclined and deflected to the same side of the air outlet 11, the first surface 1214 of the blade body 121 faces the inner side of the air outlet 11, and the second surface 1215 of the blade body 121 faces the outer side of the air outlet 11 (see Figure 2 ).

[0150] In addition, a reference plane A of the blade body is defined in this embodiment (seeFigure 10 As shown in FIG. 1, the reference plane A is a normal projection plane of the blade body 121, which is a projection plane formed by normal projection of the blade body 121. In addition, the reference plane A of the blade body 121 includes the central axis of the blade body 121, or in other words, the central axis of the blade body 121 passes through the reference plane A.

[0151] It can be understood that, as shown in the blade body 121 in FIGS. 1 to 3, the first surface 1214 and the second surface 1215 of the blade body 121 are both planar, and the thickness of the blade body 121 is uniform. At this time, the central plane of the blade body 121 in the thickness direction is the reference plane A, and the first surface 1214 and the second surface 1215 of the blade body 121 are both parallel to the reference plane A. Figure 6 Figure 7 As shown in the blade body 121 in FIGS. 1 to 3, the first surface 1214 and the second surface 1215 of the blade body 121 are both planar, and the thickness of the blade body 121 is uniform. At this time, the central plane of the blade body 121 in the thickness direction is the reference plane A, and the first surface 1214 and the second surface 1215 of the blade body 121 are both parallel to the reference plane A.

[0152] As shown in the blade body 121 in FIGS. 1 to 3, the first surface 1214 and the second surface 1215 of the blade body 121 are both planar, and the thickness of the blade body 121 is uniform. At this time, the central plane of the blade body 121 in the thickness direction is the reference plane A, and the first surface 1214 and the second surface 1215 of the blade body 121 are both parallel to the reference plane A.

[0153] In this embodiment, the air outlet hole 1211 can be inclined toward the side where the first air guiding side 1212 of the blade body 121 is located, from the first surface 1214 to the second surface 1215 of the blade body 121. That is, the central axis of the air outlet hole 1211 extends obliquely toward the first air guiding side 1212, the angle between the central axis of the air outlet hole 1211 and the reference plane A of the blade body 121 on the side where the first air guiding side 1212 is located is less than 90°, and the angle between the central axis of the air outlet hole 1211 and the reference plane A of the blade body 121 on the side where the second air guiding side 1213 is located is greater than 90°.

[0154] In this way, when the air guiding blade 120 is in the open state, the angle between the extension direction of the air outlet hole 1211 and the side of the blade body 121 close to the outside of the air outlet 11 in the air supply direction of the adjusting assembly 100 is an acute angle, and the air outlet direction of the air outlet hole 1211 tends to be the air guiding direction of the blade body 121. The direction difference between the flow direction of the first air flow flowing outward along the air guiding channel between adjacent air guiding blades 120 and the flow direction of the second air flow passing through the air outlet hole 1211 and flowing outward is less than 90°.

[0155] ​When the air guide blades 120 deflect to the same side of the air outlet 11, the first air flow flowing out of the air guide channels between the adjacent air guide blades 120 deflects to the same side of the air outlet 11. At this time, the second air flow flowing out of the air outlet hole 1211 of the blade body 121 does not obviously deflect to the same side of the air outlet 11, but the second air flow does not obviously deflect to the other side of the air outlet 11. At the same time, the flow rate of the second air flow is obviously smaller than the flow rate of the first air flow. Therefore, the second air flow has little effect on the air supply direction of the adjustment assembly 100 as a whole, and the adjustment accuracy of the air supply direction and the air supply area of the adjustment assembly 100 can be ensured.

[0156] Taking the air guide blade 120 close to the left side of the air outlet 11 as an example, when the air guide blade 120 deflects to the left side of the air outlet 11, the first air flow flowing out of the air guide channels between the adjacent air guide blades 120 deflects to the left side of the air outlet 11. The flow direction of the second air flow flowing out of the air outlet hole 1211 of the blade body 121 itself can be approximately toward the front of the air outlet 11, or the flow direction of the second air flow can slightly deflect to the left side of the air outlet 11.

[0157] Therefore, by tilting the air outlet hole 1211 on the blade body 121 toward the first air guide side 1212 from the first surface 1214 to the second surface 1215 of the blade body 121, the second air flow flowing out of the air outlet hole 1211 can not only collide with the first air flow flowing along the air guide channel, but also play a role in making the air supply of the adjustment assembly 100 more gentle. At the same time, the interference of the second air flow on the air supply direction of the adjustment assembly 100 as a whole can be reduced, and the air supply adjustment accuracy of the adjustment assembly 100 can be ensured.

[0158] Specifically, the angle between the extension direction of the air outlet hole 1211 on the blade body 121 and the reference plane A is in the range of 30°-60°.

[0159] Taking the deflection angle of the blade body 121 to the same side of the air outlet 11 as 45° as a reference, the angle between the blade body 121 and the vertical direction of the air outlet 11 (the direction perpendicular to the plane of the air outlet 11) 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 deflection degree of the blade body 121 is moderate, and the air supply angle of the adjustment assembly 100 obviously deflects to the same side of the air outlet 11. The deflection angle is more appropriate for judging whether the air outlet direction of the air outlet hole 1211 is appropriate or not.

[0160] For example, the air deflection blade 120 near the left side of the air outlet 11, when the angle between the extending direction of the air outlet hole 1211 and the reference plane A is 60°, the deflection angle of the blade body 121 deflecting to the left side of the air outlet 11 is 45°, and the airflow blown by the air outlet hole 1211 deflects 15 degrees to the right side of the air outlet hole 1211. When the angle between the extending direction of the air outlet hole 1211 and the reference plane A is 30°, the deflection angle of the blade body 121 deflecting to the left side of the air outlet 11 is 45°, and the airflow blown by the air outlet hole 1211 deflects 15 degrees to the left side of the air outlet hole 1211.

[0161] Therefore, the smaller the angle between the extending direction of the air outlet hole 1211 and the reference plane A, the more the air outlet direction of the air outlet hole 1211 tends to approach the overall air supply direction of the adjustment assembly 100. When the deflection angle of the blade body 121 deflecting to the same side of the air outlet 11 is greater than 45°, it indicates that the air deflection effect of the adjustment assembly 100 to the same side of the air outlet 11 is more obvious. Therefore, by designing the angle between the extending direction of the air outlet hole 1211 and the reference plane A to be less than or equal to 60°, when the adjustment assembly 100 deflects air to the same side of the air outlet 11, the airflow blown by the air outlet hole 1211 will not be obviously deflected to the other side of the air outlet 11, and the overall adjustment effect of the adjustment assembly 100 is better.

[0162] For example, the angle between the extending direction of the air outlet hole 1211 on the blade body 121 and the reference plane A is in the range of 40°-50°. For example, the air deflection blade 120 near the left side of the air outlet 11, when the angle between the extending direction of the air outlet hole 1211 and the reference plane A is 50°, the deflection angle of the blade body 121 deflecting to the left side of the air outlet 11 is 45°, and the second airflow blown by the air outlet hole 1211 deflects 5 degrees to the right side of the air outlet hole 1211. When the angle between the extending direction of the air outlet hole 1211 and the reference plane A is 30°, the deflection angle of the blade body 121 deflecting to the left side of the air outlet 11 is 45°, and the second airflow blown by the air outlet hole 1211 deflects 15 degrees to the left side of the air outlet hole 1211.

[0163] In this way, when the blowing angle of the adjusting assembly 100 is obviously deflected to the same side of the air outlet 11, the second airflow blown out of the air outlet hole 1211 of the blade body 121 is approximately blown to the front of the air outlet 11, or the second airflow blown out of the air outlet hole 1211 is also deflected to the same side of the air outlet 11. In this way, the air outlet hole 1211 can avoid affecting the overall blowing direction of the adjusting assembly 100. Moreover, the inclination degree of the air outlet hole 1211 is not too large, and the air outlet hole 1211 is convenient to process on the blade body 121. In addition, the air outlet hole 1211 occupies a moderate space in the planar direction of the blade body 121, and a sufficient number of air outlet holes 1211 can be processed on the blade body 121 to ensure the blowing amount of the air outlet holes 1211 of the blade body 121.

[0164] For example, the angle between the extension direction of the air outlet hole 1211 on the blade body 121 and the reference plane A is 45°. Taking the air deflection blade 120 close to the left side of the air outlet 11 as an example, when the angle between the extension direction of the air outlet hole 1211 and the reference plane A is 45°, the deflection angle of the blade body 121 to the left side of the air outlet 11 is 45°, and the angle between the second airflow blown out of the air outlet hole 1211 and the vertical direction of the air outlet 11 is 0°, and the second airflow is blown to the front of the air outlet 11. In this way, when the blowing angle of the adjusting assembly 100 is obviously deflected to the same side of the air outlet 11, the airflow blown out of the air outlet hole 1211 is also deflected to the same side of the air outlet 11.

[0165] As for the shape of the air outlet hole 1211 on the blade body 121, the present embodiment does not make specific limitations. The air outlet hole 1211 can have a relatively regular shape, and stress concentration phenomenon can be avoided. For example, the cross-sectional shape of the air outlet hole 1211 can be circular, elliptical or regular polygonal. When the cross-sectional shape of the air outlet hole 1211 is regular polygonal, the cross-sectional shape of the air outlet hole 1211 is, for example, regular pentagonal, regular hexagonal, regular octagonal, etc.

[0166] The appropriate size of the air outlet hole 1211 can be processed on the blade body 121 according to the size of the blade body 121. Taking the air outlet hole 1211 as a circular hole as an example, the hole diameter of the air outlet hole 1211 can be between 4mm-9mm. In this way, the air outlet hole 1211 has a sufficient cross-sectional area, and the air outlet hole 1211 meets the blowing demand, and ensures that the air outlet hole 1211 on the blade body 121 has a certain blowing amount. Moreover, the cross-sectional area of the air outlet hole 1211 is not too large, and a sufficient number of air outlet holes 1211 can be provided on the blade body 121 to avoid affecting the structural strength and reliability of the blade body 121.

[0167] Exemplarily, the hole diameter of the air outlet hole 1211 can be 4.5 mm, 5.0 mm, 5.5 mm, 6.0 mm, 6.5 mm, 7.0 mm, 7.5 mm, 8.0 mm, 8.5 mm, etc.

[0168] Figure 8 Another structural schematic diagram of the air guide assembly provided by the embodiment of the present application. Figure 9 For Figure 8 the front view of the air guide assembly in

[0169] Referring to Figure 8 and Figure 9 shown, the embodiment also designs the shape of the air guide blade 120 in the adjustment assembly 100, further adjusts the air supply direction through the air guide blade 120, enhances the flexibility of the adjustment assembly 100 in adjusting the air supply area, and further expands the air supply coverage area of the air guide assembly 20.

[0170] Specifically, the embodiment sets the blade body 121 of at least part of the air guide blade 120 in the adjustment assembly 100 to a curved surface shape. For these curved surface shaped blade bodies 121, taking the central axis of the blade body 121 as a boundary line, the blade body 121 has a first curved portion 1216 on one side of the central axis thereof.

[0171] Figure 10 For Figure 9 the partial enlarged view of the air guide blade in Figure 10 shown, in some embodiments, when the air guide blade 120 is in the open state, the first curved portion 1216 in the blade body 121 can be located outside the air outlet. At this time, the first air guide side 1212 is the side of the first curved portion 1216 away from the central axis of the blade body 121, and the first curved portion 1216 causes the first air guide side 1212 to be inclined to 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 air guide side 1212 deviates from the reference plane A, and the first air guide side 1212 has an included angle α between the extension line thereof and the reference plane A.

[0172] When the air handling equipment 1 is in the working state, the blade bodies 121 of the adjacent air guide blades 120 form an air guide channel, and the airflow at the air outlet 11 is blown to the outside along the air guide channel. Since one side of the blade body 121 is the first curved portion 1216, the first curved portion 1216 can cause the airflow passing through the air guide channel to produce a Coanda effect, changing the flow direction of the airflow. In turn, the air supply direction of the adjustment assembly 100 is changed, and the air supply area of the air guide assembly 20 is adjusted.

[0173] 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.

[0174] Therefore, when the airflow in the duct flows towards the outlet 11, it passes over the surface of the first bend 1216, and friction occurs between the airflow and the surface of the first bend 1216. This changes the direction of the airflow, causing it to flow along the surface of the first bend 1216. 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 1212. In other words, the extension direction of the first guide side 1212 can be considered as the air delivery direction of the guide blade 120.

[0175] This configuration guides the airflow direction of the outlet 11 via the first guide side 1212, causing the airflow to flow along the extension direction of the first guide side 1212. The extension line of the first guide side 1212 forms an angle with the reference plane A where the blade body 121 is located, effectively changing the direction of the airflow that would normally flow along the extension direction of the reference plane A. Furthermore, the air delivery angle of the adjustment component 100 can be changed, making the adjustment of the air delivery area by the guide component 20 more flexible and further expanding the air delivery coverage area of ​​the air handling unit 1.

[0176] When the air handling unit 1 is in operation, since the first air guide side 1212 is the side from which the airflow exits the air guide channel, the first curved portion 1216 in the blade body 121 can be located on the outer side of the air outlet 11, on the first air guide side 1212. In this way, the airflow flows along the surface of the first curved portion 1216, and when the airflow is blown to the outside, it can flow along the extension direction of the first air guide side 1212, thereby changing the air delivery direction of the regulating component 100.

[0177] Furthermore, in order to expand the air delivery area of ​​the adjustment component 100, the first curved portion 1216 can deflect the first air guide side 1212 toward the same side as the air outlet 11. (Refer to...) Figure 10 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 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 first 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 first guide side 1212 can extend to the left side of the air outlet 11.

[0178] In order to make the adjustment assembly 100 have a larger air supply coverage area, the air guide blades 120 are generally made to guide air to the same side of the air outlet 11. For example, the air guide blades 120 close to the left side of the length direction of the air outlet 11 guide air to the left side of the air outlet 11, and the air guide blades 120 close to the right side of the length direction of the air outlet 11 guide air to the right side of the air outlet 11. By making the extension line of the first air guide side 1212 extend to the same side of the air outlet 11, the first air guide side 1212 can further increase the air supply deflection angle of the air guide blades 120 when the air guide blades 120 guide air to the same side of the air outlet 11. In turn, the air supply area of the adjustment assembly 100 is expanded.

[0179] The air guide blades described above guide air to the same side of the air outlet. This is illustrated by the following two examples: for the air guide blades 120 close to the left side of the length direction of the air outlet 11, when the air guide blades 120 guide air to the left side of the air outlet 11, the first air guide side 1212 can further deflect the air supply angle of the air guide blades 120 to the left side of the air outlet 11. For the air guide blades 120 close to the right side of the length direction of the air outlet 11, when the air guide blades 120 guide air to the right side of the air outlet 11, the first air guide side 1212 can further deflect the air supply angle of the air guide blades 120 to the right side of the air outlet 11. In this way, the air supply deflection angles of the air guide assembly 20 to the left and right sides of the air outlet 11 are increased, and the air supply area and coverage area of the air guide assembly 20 are expanded.

[0180] Of course, in some embodiments, the first curved portion 1216 in the blade body 121 can also be located on the inner side of the air outlet 11 when the air handling device 1 is in operation, and at this time, the second air guide side 1213 is the side of the first curved portion 1216 away from the central axis of the blade body 121. Since the second air guide side 1213 is the side through which the airflow flows into the air guide channel, the flow direction of the airflow can be changed when the airflow flows into the air guide channel. After the airflow flows along the surface of the first curved portion 1216 in the air guide channel, the flow direction of the airflow is changed. In turn, the flow direction of the airflow after flowing out of the air guide blade 120 is also changed, thereby changing the air supply direction of the adjustment assembly 100.

[0181] At this time, in order to expand the air supply area of the adjusting assembly 100, the first bending part 1216 can also make the second air guiding side 1213 incline to the same side of the air outlet 11. When the air guiding blade 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the second air guiding side 1213 can extend to the same side of the air outlet 11. In this way, when the air guiding blade 120 needs to guide air to the same side of the air outlet 11, the extension line of the first air guiding side 1212 of the air guiding blade 120 is perpendicular to the plane where the air outlet 11 is located, or the extension line of the first air guiding side 1212 of the air guiding blade 120 inclines to the other side of the air outlet 11, so as to ensure that the overall air flow is inclined to the same side of the air outlet 11 when the air flow flows out of the air outlet 11.

[0182] For example, the air guiding blade 120 near the left side of the air outlet 11 in the length direction is taken as an example. When the air guiding blade 120 guides air to the left side of the air outlet 11, the extension line of the second air guiding side 1213 of the air guiding blade 120 located inside the air outlet 11 can be perpendicular to the plane where the air outlet 11 is located, or the extension line of the second air guiding side 1213 of the air guiding blade 120 extends to the inside of the air outlet 11 and inclines to the right side of the air outlet 11. In this way, the overall air guiding blade 120 is inclined to the left side of the air outlet 11, and air can be guided to the left side of the air outlet 11.

[0183] In this way, the center line of the air outlet 11 in the length direction is taken as a boundary. When the air handling equipment 1 works, the air guiding blade 120 located on the left side of the air outlet 11 can be deflected to the left (for example, the air guiding blade 120 in the adjusting assembly 100 located on the left side of the two adjusting assemblies 100 is deflected to the left), and the air guiding effect of the first bending part 1216 can expand the air supply angle and the air supply area of the air supply to the left side of the air outlet 11. At the same time, the air guiding blade 120 located on the right side of the air outlet 11 can be deflected to the right (for example, the air guiding blade 120 in the adjusting assembly 100 located on the right side of the two adjusting assemblies 100 is deflected to the right), and the air guiding effect of the first bending part 1216 can expand the air supply angle and the air supply area of the air supply to the right side of the air outlet 11. Thus, the air supply coverage area of the air handling equipment 1 is significantly expanded.

[0184] Alternatively, the air guiding blades 120 located on both sides of the air outlet 11 can be deflected to the left (for example, the air guiding blades 120 in the two adjusting assemblies 100 are deflected to the left). At this time, the angle of deflection of all the air guiding blades 120 on the left side of the air outlet to the left side of the air outlet is increased. In addition, the bearing plate 110 in the adjusting assembly 100 on the right side can be deflected to the left to increase the angle of deflection of the air guiding blades 120 thereon to the left. Evenly, the bearing plate 110 in the adjusting assembly 100 on the left side can be deflected to the left to increase the angle of deflection of the air guiding blades 120 thereon to the left. Thus, the angle of air guiding to the left side of the air handling equipment 1 is significantly increased.

[0185] Similarly, the air guide vanes 120 on both sides of the air outlet 11 can be deflected to the right (for example, the air guide vanes 120 in both adjustment assemblies 100 are deflected to the right). At this time, the deflection angles of all the air guide vanes 120 on the right side of the air outlet to the right side of the air outlet are increased. In addition, the bearing plate 110 in the left adjustment assembly 100 can be deflected to the right to increase the deflection angle of the air guide vanes 120 thereon to the right. Even the bearing plate 110 in the right adjustment assembly 100 can be deflected to the right to increase the deflection angle of the air guide vanes 120 thereon to the right. Thus, the deflection angle of the air handling equipment 1 to the right side is obviously increased.

[0186] The following are all examples in which the air handling equipment 1 is in a working state, the first bending part 1216 of the vane body 121 of the air guide vane 120 is located on the outside of the air outlet 11, and the first air guide side 1212 is inclined to the same side of the air outlet 11.

[0187] Specifically, taking one air guide vane 120 near the left side of the length direction of the air outlet 11 as an example, if the included angle between the extension line of the first air guide side 1212 of the air guide vane 120 and the reference plane A is 30°. When the air guide vane 120 is perpendicular to the plane of the air outlet 11, the included angle between the extension line of the first air guide side 1212 and the perpendicular line of the air outlet 11 (a line perpendicular to the plane of the air outlet 11) is 30°, that is, the deflection angle of the air guide vane 120 to the left is 30°. When the air guide vane 120 is deflected to the left by 15°, the included angle between the extension line of the first air guide side 1212 and the perpendicular line of the air outlet 11 is 45°, that is, the deflection angle of the air guide vane 120 to the left is 45°.

[0188] In this way, when the air guide vane 120 guides air to the same side of the air outlet 11, the vane body 121 of the air guide vane 120 is deflected to the same side of the air outlet 11 by a certain angle, and the included angle between the first air guide side 1212 of the vane body 121 and the reference plane A is increased to make the first air guide side 1212 deflect to the same side of the air outlet 11 by a larger angle. The deflection angle of the vane body 121 is increased, the air guide area of the adjustment assembly 100 is larger, and the air guide coverage area is wider.

[0189] At the same time, on the basis of the certain deflection angle of the air guide vane 120, the deflection angle of the vane body 121 is the required deflection angle minus the included angle between the first air guide side 1212 of the vane body 121 and the reference plane A, and the required deflection angle of the vane body 121 is smaller. In this way, the rotation angle of the drive motor 201 driving the vane body 121 to rotate is smaller, the energy consumption of the drive motor 201 is less, which is conducive to saving the energy consumption of the adjustment assembly 100 and reducing the overall energy consumption of the air handling equipment 1.

[0190] With reference back to Figure 10 In some embodiments, on the basis of one side of the blade body 121 being designed as the first curved portion 1216, the other side of the blade body 121 can also be designed as a second curved portion 1217. That is, both sides of the central axis of the blade body 121 are designed as curved portions. The second curved portion 1217 is on the side away from the central axis of the blade body 121, that is, the second air guiding side 1213 of the blade body 121. The extension direction of the second air guiding side 1213 also deviates from the reference plane A, and the extension line of the second air guiding side 1213 has an included angle with the reference plane A.

[0191] With reference to the case that the air guiding blade 120 is in the vertical state, the air guiding blade 120 is perpendicular to the plane where the air outlet 11 is located, the first air guiding side 1212 is located on the outside of the air outlet 11, and the extension line of the first air guiding side 1212 extends to the same side of the air outlet 11. The second air guiding side 1213 is located on the inside of the air outlet 11, and the extension line of the second air guiding side 1213 extends to the opposite side of the air outlet 11. Still taking the case that the air guiding blade 120 is close to the left side of the air outlet 11 as an example, when the air guiding blade 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the first air guiding side 1212 located on the outside of the air outlet 11 can extend to the left side of the air outlet 11, and the extension line of the second air guiding side 1213 located on the inside of the air outlet 11 can extend to the right side of the air outlet 11.

[0192] In this way, for the air guiding blade 120 capable of rotating by 360°, when the air guiding blade 120 is rotated to the second air guiding side 1213 of the blade body 121 located on the outside of the air outlet 11, the second air guiding side 1213 also deviates to the left side of the air outlet 11, as the first air guiding side 1212 does when it is located on the outside of the air outlet 11. In this way, the air guiding blade 120 can also be rotated to the second air guiding side 1213 located on the outside of the air outlet 11, and the air guiding blade 120 guides the airflow blown out of the air outlet 11 by the second air guiding side 1213, and increases the air supply deflection angle of the air guiding blade 120 through the second air guiding side 1213.

[0193] When the air handling device 1 is in operation, either the first air guiding side 1212 of the air guiding blade 120 can be directed to the outside of the air outlet 11, or the second air guiding side 1213 of the air guiding blade 120 can be directed to the outside of the air outlet 11, and the air guiding blade 120 can increase the air deflection angle by using either the first air guiding side 1212 or the second air guiding side 1213. In this way, the rotation angle of the air guiding blade 120 is not limited, the control of the air guiding blade 120 is more flexible, and the operation mode is simpler. Moreover, when the air guiding blade 120 is installed, the first air guiding side 1212 and the second air guiding side 1213 of the air guiding blade 120 do not need to be deliberately distinguished, the positioning requirement of the air guiding blade 120 is weaker, the installation of the air guiding blade 120 is facilitated, the assembly efficiency of the air guiding blade 120 can be improved, and the probability of installation failure of the air guiding blade 120 is reduced.

[0194] For example, the bending shape of the second bending part 1217 can be completely consistent with the bending shape of the first bending part 1216, and the blade body 121 of the air guiding blade 120 is a central symmetric structure. When the rotation shaft 122 of the air guiding blade 120 is located on the central axis of the blade body 121, the air guiding blade 120 as a whole is a central symmetric structure.

[0195] In this way, whether the first air guiding side 1212 is located on the outside of the air outlet 11 or the second air guiding side 1213 is located on the outside of the air outlet 11, the air deflection angle of the air guiding blade 120 is the same when the blade body 121 is deflected to a certain angle, and the air guiding blade 120 can have the same air adjustment effect. Moreover, the air guiding blade 120 has good structural symmetry, balanced stress, better stability, and higher reliability. In addition, because the air guiding blade 120 is a symmetric structure, the operability of the air guiding blade 120 during installation is better, the two sides of the air guiding blade 120 do not need to be distinguished and positioned, the installation efficiency of the air guiding blade 120 is higher, and the appearance effect of the adjustment assembly 100 is better.

[0196] In other embodiments, only one side of the blade body 121 can be designed as the first bending part 1216, and the other side of the blade body 121 can be designed as a straight part. The extension direction of the straight part can be designed according to the reference plane A of the blade body 121, the straight part can extend along the extension direction of the reference plane A, and the central plane of the straight part in the thickness direction can be located in the reference plane A.

[0197] When one side of the blade body 121 is the first curved portion 1216 and the other side is the flat portion, the first curved portion 1216 of the blade body 121 can be arranged to face the first air guiding side 1212 of the air guiding blade 120 when the air guiding blade 120 is installed. The rotation angle range of the air guiding blade 120 can be controlled so that the first curved portion 1216 of the blade body 121 is always located outside the air outlet 11, and the flat portion of the blade body 121 is always located inside the air outlet 11. The first air guiding side 1212 is used to guide the air flow, and the blowing angle of the air guiding blade 120 is changed.

[0198] Of course, as mentioned above, the flat portion of the blade body 121 can be located outside the air outlet 11, and the first curved portion 1216 of the blade body 121 can be located inside the air outlet 11. The first curved portion 1216 is used to adjust the flow direction of the air flow entering the air guiding channel, so that the blowing angle of the air guiding blade 120 is changed. Here, no further description is given.

[0199] As for the overall design of the air guiding blades 120 in the entire adjusting assembly 100, all the air guiding blades 120 can be designed as curved shapes. In this way, the first air guiding side 1212 of all the air guiding blades 120 can increase the blowing deflection angle of the air guiding blade 120. The blowing angle of the entire adjusting assembly 100 can be changed, so that the deflection angle of the blowing area of the entire adjusting assembly 100 is increased.

[0200] Alternatively, part of the air guiding blades 120 can be designed as curved shapes, and the remaining air guiding blades 120 can remain as flat shapes. The air guiding blades 120 with curved shapes can increase the blowing deflection angle of the corresponding area of the adjusting assembly 100. The remaining air guiding blades 120 with flat shapes can maintain the original blowing deflection angle of the corresponding area of the adjusting assembly 100.

[0201] At this time, the air guiding blades 120 closer to the end of the air outlet 11 can be designed as curved shapes, and the air guiding blades 120 closer to the center of the air outlet 11 can be designed as flat shapes. The blowing deflection angle of the air guiding blades 120 closer to the center of the air outlet 11 is smaller, and the blowing deflection angle of the air guiding blades 120 closer to the end of the air outlet 11 is larger. From the center of the air outlet 11 to the end of the air outlet 11, the blowing deflection angle of the adjusting assembly 100 is increased. In this way, the blowing area of the adjusting assembly 100 is larger, the blowing coverage is wider, and the air outlet is more gentle.

[0202] In the adjusting assembly 100, whether only part of the air guide blades 120 are designed as curved shapes or all the air guide blades 120 are designed as curved shapes, all the air guide blades 120 in the curved shapes can keep the same shape. In this way, the air guide blades 120 in the curved shapes have the same air supply adjusting effect on the corresponding area of the adjusting assembly 100.

[0203] Alternatively, in the direction close to 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, among the air guide blades 120 in the curved shapes, the included angle between the extension line of the first air guide side 1212 of each air guide blade 120 and the reference plane A can gradually increase. In this way, from the center of the air outlet 11 to the end of the air outlet 11, the air supply deflection angle of the adjusting assembly 100 gradually increases, the air supply area of the adjusting assembly 100 is larger and the air supply coverage is wider, and the air supply area gradually expands outward, the air volume is more dispersed, and the air supply is more gentle.

[0204] Referring to Figure 6 Taking the air guide assembly 20 with two adjusting assemblies 100 as an example, when the air handling device 1 is working, in the adjusting assembly 100 located on the left side of the length direction of the air outlet 11, the first air guide side 1212 of the air guide blade 120 in the curved shape is inclined to the left side of the air outlet 11. In the adjusting assembly 100 located on the right side of the length direction of the air outlet 11, the first air guide side 1212 of the air guide blade 120 in the curved shape is inclined to the right side of the air outlet 11. The air supply area of the air guide assembly 20 can be expanded to the left and right sides, and the air supply coverage of the air guide assembly 20 can be increased. In addition, the bearing plates 110 of the two adjusting assemblies 100 relatively swing outward, which can further expand the air supply coverage of the air guide assembly 20.

[0205] The air guide blade 120 in the curved shape will be described in detail below, and the first curved part 1216 of the air guide blade 120 will be specifically described. It can be understood that when the other side of the air guide blade 120 is designed as the second curved part 1217, the second curved part 1217 has the same characteristics as the first curved part 1216 when the shape of the second curved part 1217 is exactly the same as that of the first curved part 1216.

[0206] Referring to Figure 7As shown, the angle a between the extension line of the first air guiding side 1212 of the air guiding blade 120 and the reference plane A can be in the range of 5°-45°. With the plane direction of the air guiding blade 120 perpendicular to the air outlet 11 as the reference, when the angle a between the extension line of the first air guiding side 1212 and the reference plane A is 5°, the air blowing direction of the air guiding blade 120 deflects 5° to the same side of the air outlet 11; the air guiding blade 120 continues to deflect 85° to the same side of the air outlet 11, i.e. the extension line of the first air guiding side 1212 is parallel to the plane direction of the air outlet 11. When the angle a between the extension line of the first air guiding side 1212 and the reference plane A is 45°, the air blowing direction of the air guiding blade 120 deflects 45° to the same side of the air outlet 11; the air guiding blade 120 continues to deflect 45° to the same side of the air outlet 11, i.e. the extension line of the first air guiding side 1212 is parallel to the plane direction of the air outlet 11.

[0207] In this way, the air guiding blade 120 only needs to rotate in a small angle range, so that the air guiding blade 120 has an air blowing area with a large angle range. The air guiding blade 120 can flexibly adjust the air blowing angle and change the air blowing area of the adjusting assembly 100. Moreover, the angle between the extension line of the first air guiding side 1212 and the reference plane A is not too large, the bending degree of the first bending part 1216 is appropriate, and the air guiding blade 120 will not hinder the flow of air. The air resistance of the whole adjusting assembly 100 is small, which will not affect the air blowing amount of the air handling device 1.

[0208] For example, the angle a between the extension line of the first air guiding side 1212 and the reference plane A can be in the range of 25°-45°. By making the angle a between the extension line of the first air guiding side 1212 and the reference plane A greater than or equal to 25°, when the plane direction of the air guiding blade 120 is perpendicular to the air outlet 11, the deflection angle of the air blowing direction of the air guiding blade 120 to the same side of the air outlet 11 is greater than or equal to 25°. The first air guiding side 1212 can obviously increase the air blowing deflection angle of the air guiding blade 120, and can better expand the air blowing area of the adjusting assembly 100.

[0209] For example, the angle a between the extension line of the first air guiding side 1212 and the reference plane A can be 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, etc.

[0210] Continuing to refer to Figure 7The first curved portion 1216 of the blade body 121 can be a smooth curved portion, and the overall curved shape of the first curved portion 1216 is relatively gentle. The first curved portion 1216 can make the airflow flow smoothly along its surface, change the flow direction of the airflow, and not hinder the flow of the airflow. The airflow flows smoothly along the first curved portion 1216 to the air outlet 11 to stably blow the airflow to the outside.

[0211] In addition, the first curved portion 1216 can have only one curved vertex 12161. That is, the first curved portion 1216 is curved only once to one side of the thickness direction of the blade body 121. In order to realize the same side deflection of the first air guide side 1212 to the air outlet 11, the first curved portion 1216 can be slightly convex to the other side of the air outlet 11. In this way, the first curved portion 1216 is avoided to form a continuously concave and convex wave surface, so as to avoid the first curved portion 1216 to change the flow direction of the airflow multiple times, avoid the influence on the air supply direction of the air guide blade 120, and ensure the adjustment effect of the first curved portion 1216 on the air supply deflection angle of the air guide blade 120. It can also avoid the airflow to be turbulent when flowing through the first curved portion 1216, so as to ensure that the airflow can flow out of the air guide blade 120 smoothly and orderly, and avoid the loss of the air supply amount of the air treatment equipment 1.

[0212] When the first curved portion 1216 has only one curved vertex 12161, the extension line of the first air guide side 1212 extends to one side of the reference plane A, and the curved vertex 12161 can be located on the other side of the reference plane A. Taking the air guide blade 120 close to the left side of the length direction of the air outlet 11 as an example, and taking the air guide blade 120 perpendicular to the plane where the air outlet 11 is located as a reference, the extension of the first air guide side 1212 of the air guide blade 120 can extend to the left side of the reference plane A, and the curved vertex 12161 can be located on the right side of the reference plane A.

[0213] In this way, the extension line of the first air guide side 1212 and the curved vertex 12161 of the first curved portion 1216 are located on the same side of the reference plane A, and the first curved portion 1216 is avoided to be excessively curved to one side of the air guide blade 120. The air guide blade 120 is flat as a whole, and the bending degree is small, and the air resistance is small. In the long-term use process of the air guide blade 120, the air guide blade 120 is less compressed by the airflow, the reliability of the air guide blade 120 is higher, and the service life is longer. In addition, the air guide blade 120 is still flat as a whole, occupies less space, and is convenient for the arrangement of the air guide blade 120 on the bearing plate 110.

[0214] Exemplarily, the first curved portion 1216 is away from the first air guide side 1212 of the central axis of the blade body 121, and the center line in the thickness direction can be located on the reference plane A. In this way, the bending shape of the first curved portion 1216 is constrained, and the first curved portion 1216 is limited within a smaller bending amplitude, the smoothness of the blade body 121 is higher, the fluid resistance is smaller, and it is more in line with the high-efficiency air supply demand of the air handling device 1.

[0215] When the other side of the blade body 121 is provided with the second curved portion 1217, and the second curved portion 1217 is the same shape as the first curved portion 1216, or the other side of the blade body 121 is provided with a straight portion, the center line of the second air guide side 1213 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 the reference plane A thereof, the overall design of the blade body 121 tends to be planar, the shape is more regular, the air guide effect is good, and the stability and reliability are high.
