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 devices, in particular to an air guide vane, an adjusting assembly, an air guide assembly and an air treatment device. BACKGROUND

[0003] An air treatment device, such as an air conditioner, usually comprises an air outlet and an air guide plate arranged at the air outlet. The air guide plate is rotationally connected at the air outlet, and the air guide direction of the air outlet is changed by changing the angle at which the air guide plate is opened relative to the air outlet.

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

[0005] The present application provides an air guide vane, an adjusting assembly, an air guide assembly and an air treatment device. The air guide vane can change the air guide angle of the adjusting assembly, and the air guide area of the air guide assembly is more flexible, which can expand the air guide coverage area of the air treatment device.

[0006] The first aspect of the present application provides an air guide vane for being installed at an air outlet of an air treatment device, the air guide vane being movable between an inner side of the air outlet and an outer side of the air outlet; the air guide vane comprising a vane body, the vane body comprising a first curved portion, the first curved portion being located at one side of a central axis of the vane body; a first air guide side of the first curved portion being away from the central axis, the first air guide side having an included angle between an extension line of the first air guide side and a reference plane, the reference plane being a normal projection plane of the vane body and the reference plane passing through the central axis.

[0007] The air guide vane provided by the present application can be moved between the inner side of the air outlet and the outer side of the air outlet. In this way, the position of the air guide vane relative to the air outlet can be changed, and the interference phenomenon between the air guide vane and the air duct is obviously improved. The deflection angle of the air guide vane is weakened by the influence of the air duct, and the deflection angle range of the air guide vane can be expanded, and the air guide coverage area of the air treatment device can be expanded.

[0008] And, by arranging the first curved portion on the blade body of the guide vane, the first curved portion is located on one side of the central axis of the blade body. The side of the first curved portion away from the central axis is the first guide side of the guide vane. When the air handling equipment is in the working state and the air outlet is opened, the first curved portion can make the airflow passing through the surface of the blade body produce a Coanda effect, so that the airflow flows along the surface of the first curved portion to change the flow direction of the airflow blown out of the air outlet. By arranging the first curved portion to have an included angle between the extension line of the first guide side and the reference plane on which the blade body is located, the first guide side can change the blowing angle of the adjustment assembly, so that the guide assembly is more flexible in adjusting the blowing area, and the blowing coverage area of the air handling equipment is further expanded.

[0009] In a possible implementation, the first curved portion is located outside the air outlet when the guide vane is in the open state.

[0010] In this way, when the guide vane is in the open state, the airflow flows along the surface of the first curved portion, and the airflow blown to the outside can flow along the extension direction of the first guide side to change the blowing direction of the adjustment assembly.

[0011] In a possible implementation, the extension line of the first guide side extends to the same side of the air outlet when the guide vane is perpendicular to the plane on which the air outlet is located.

[0012] By arranging the first guide side to have an extension line extending to the same side of the air outlet, the first guide side can further increase the blowing deflection angle of the guide vane when the guide vane guides air to the same side of the air outlet. In turn, the blowing area of the adjustment assembly is expanded.

[0013] In a possible implementation, the included angle between the extension line of the first guide side and the reference plane is in the range of 5°-45°.

[0014] In this way, the guide vane only needs to rotate within a small angle range to have a large angle range of the blowing area. Moreover, the included angle between the extension line of the first guide side and the reference plane is not too large, the bending degree of the first curved portion is appropriate, and the guide vane does not hinder the flow of the airflow. The overall air resistance of the adjustment assembly is small, and the blowing amount of the air handling equipment is not affected.

[0015] In a possible implementation, the included angle between the extension line of the first guide side and the reference plane is in the range of 25°-45°.

[0016] In this way, the first guide side can significantly increase the blowing deflection angle of the guide vane, and can better expand the blowing area of the adjustment assembly.

[0017] In a possible implementation, the first curved portion is a smooth curved portion, and the first curved portion has only one curved vertex.

[0018] In this way, the bending shape of the first bending part as a whole is relatively gentle, so that the airflow can flow smoothly along the surface thereof, and the airflow is changed in direction without being hindered. In addition, the first bending part is bent only once to one side of the thickness direction of the blade body, so that the first bending part is prevented from forming a wavy surface, so as to prevent the first bending part from changing the direction of the airflow multiple times and affecting the blowing direction of the air guide blade, and the adjustment effect of the first bending part on the blowing deflection angle of the air guide blade is ensured.

[0019] In a possible implementation, the extension line of the first air guide side extends to one side of the reference plane, and the bending apex is located on the other side of the reference plane.

[0020] In this way, the extension line of the first air guide side and the bending apex of the first bending part are prevented from being located on the same side of the reference plane, so that the first bending part is prevented from being excessively bent to one side of the air guide blade. The air guide blade as a whole is flat and has a small bending degree, so that the air resistance is small. In the long-term use of the air guide blade, the reliability of the air guide blade is higher, and the service life is longer.

[0021] In a possible implementation, the center line of the first air guide side in the thickness direction is located on the reference plane.

[0022] In this way, the bending shape of the first bending part is constrained, so that the first bending part is limited within a small bending range, the smoothness of the blade body is higher, the fluid is less hindered, and the high-efficiency blowing requirement of the air treatment equipment is better met.

[0023] In a possible implementation, the blade body further comprises a second bending part, the second bending part is located on the other side of the central axis of the blade body; the side of the second bending part away from the central axis is a second air guide side, and an extension line of the second air guide side extends to the other side of the reference plane.

[0024] In this way, for the air guide blade capable of rotating by 360°, when the second air guide side of the blade body is located on the outside of the air outlet, the second air guide side is also inclined to the left side of the air outlet, like the first air guide side. The air guide blade can also be rotated to the second air guide side located on the outside of the air outlet, and the air guide blade guides the airflow blown out of the air outlet by the second air guide side, so as to increase the blowing deflection angle of the air guide blade by the second air guide side.

[0025] 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.

[0026] In this way, when either the first air guiding side or the second air guiding side is located outside the air outlet, the air deflection angle of the air guiding vane is the same when the vane body is deflected to a certain angle. In addition, the air guiding vane is balanced in force, and has better stability and higher reliability. In addition, since the air guiding vane has a symmetrical structure, the two sides of the air guiding vane do not need to be distinguished during installation, the installation efficiency of the air guiding vane is higher, and the appearance effect of the adjusting assembly is better.

[0027] In a possible implementation, the vane body further comprises a flat portion, the flat portion is located on the other side of the central axis of the vane body, and a central surface of the flat portion in the thickness direction is located in the reference plane.

[0028] In a possible implementation, a plurality of air outlet holes are distributed on the vane body, and the air outlet holes penetrate through the two side surfaces of the vane body in the thickness direction.

[0029] In this way, the airflow blown out of the air duct can flow outward along the air guiding channel formed between adjacent air guiding vanes, and can also flow outward through the air outlet holes on the vane body. The two parts of airflow interact with each other, so that the strong wind blown out of the air outlet can be avoided, the air supply effect of the air treatment equipment can be made more gentle, and the use comfort of the air treatment equipment can be improved.

[0030] In a possible implementation, the air outlet hole extends obliquely towards the first air guiding side from the first surface of the vane body to the second surface of the vane body, the first surface and the second surface are the two side surfaces of the vane body in the thickness direction, and the extension line of the first air guiding side extends towards the side where the first surface is located.

[0031] In this way, when the air guiding 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 outside of the air outlet in the air supply direction of the adjusting assembly is an acute angle, and the air outlet direction of the air outlet hole tends to the air guiding direction of the vane body. The airflow blown out of the air outlet hole has little effect on the air supply direction of the whole adjusting assembly, so that the adjustment accuracy of the adjusting assembly to the air supply direction and the air supply area can be ensured.

[0032] 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°.

[0033] 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 adjusting assembly guides air to the same side of the air outlet, the airflow blown out of the air outlet hole will not obviously tend to the other side of the air outlet, and the overall adjustment effect of the adjusting assembly is better. In addition, the smaller the included angle between the extension direction of the air outlet hole and the reference plane, the more the air outlet direction of the air outlet hole tends to be close to the overall air supply direction of the adjusting assembly.

[0034] In a possible implementation, the air guide blade further comprises a rotating shaft, the rotating shaft is connected to the blade body and extends along the central axis of the blade body, and the blade body rotates around the rotating shaft.

[0035] In this way, the air guide blade is connected to the bearing plate by the rotating shaft, and the air supply direction of the adjustment assembly is changed by rotating the blade body around the rotating shaft. Moreover, 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 for movement.

[0036] 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 of which is movably connected to the bearing plate and arranged along the surface of the bearing plate in sequence; wherein at least part of the air guide blades are the air guide blades as described above.

[0037] The adjustment assembly provided by the present application adjusts the air supply angle of the adjustment assembly by arranging the air guide blades in sequence on the surface of the bearing plate and movably connecting each air guide blade to the bearing plate to change the included angle between each air guide blade and a certain direction on the surface of the bearing plate.

[0038] The adjustment assembly has all the technical effects of the air guide blade due to comprising the air guide blade, which will not be described here.

[0039] In a possible implementation, each air guide blade is arranged in sequence along the length direction of the bearing plate.

[0040] In a possible implementation, when the air guide blade is perpendicular to the plane where the air outlet is located, the extension line of the first air guide side of each air guide blade extends to the same side end of the air outlet; and the included angle between the extension line of the first air guide side of each air guide blade and the reference plane gradually increases in the direction close to the end of the air outlet.

[0041] In this way, the air supply deflection angle of the adjustment assembly gradually increases from the center of the air outlet to the end of the air outlet, the air supply area of the adjustment assembly is larger and the air supply coverage is wider, and the air supply area gradually expands outward, so that the air volume is more dispersed and the air supply is more gentle.

[0042] The third aspect of the present application provides an air guide assembly installed at an air outlet of an air handling device, the air guide assembly comprising: the adjustment assembly as described above; and a first driving assembly connected to the adjustment assembly and driving each air guide blade in the adjustment assembly to change the position relative to the bearing plate.

[0043] The air guide assembly provided in the application drives each air guide blade to move by the first driving assembly, so as to change the included angle between each air guide blade and a certain direction on the surface of the bearing plate, and adjust the air supply angle of the adjusting assembly.

[0044] The air guide assembly has all the technical effects of the air guide blade, which will not be repeated here.

[0045] In a possible implementation, the first driving assembly also drives the bearing plate in the adjusting assembly to move.

[0046] In this way, the first driving assembly drives each air guide blade on the bearing plate to move and drives the air guide blade 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 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.

[0047] Moreover, the first driving assembly drives the air guide blade to move and drives the bearing plate to move, which simplifies the driving mode of the air guide assembly, can reduce the number and occupied space of the driving assembly, and is conducive to reducing the energy consumption of the air guide assembly.

[0048] In a possible implementation, the number of adjusting assemblies is two, and the two adjusting assemblies are arranged at intervals along the length direction of the air outlet.

[0049] In this way, the two adjusting assemblies can supply air to different areas respectively, which can expand the air supply area of the air guide assembly and expand the air supply coverage area of the air handling device. 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 heating target in a shorter time, and the energy efficiency is higher.

[0050] In a possible implementation, the air guide assembly further comprises at least one second driving assembly, the second driving assembly is connected between the adjacent two adjusting assemblies, and the second driving assembly drives the bearing plates in the two adjusting assemblies to move.

[0051] By arranging the first driving assembly to drive the air guide blade 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 air guide assembly is higher.

[0052] The fourth aspect of the present application provides an air treatment device, comprising a device body and the air guide assembly as described above.

[0053] The air treatment device provided by the present application has all the technical effects of the air guide assembly, which will not be repeated here. BRIEF DESCRIPTION OF DRAWINGS

[0076] 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, the horizontally arranged air guide plates swing up and down to achieve up and down air sweeping, and the 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.

[0077] However, the above-mentioned method of adjusting the air supply area has a positive correlation between the size of the air supply area and the size of the air outlet. This results 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.

[0078] Therefore, the embodiments of the present application provide an air guide blade, an adjustment assembly, an air guide assembly, and an air treatment device. The air guide assembly is installed at the air outlet of the air treatment device, and the air guide assembly includes at least one adjustment assembly. Each adjustment assembly is provided with a plurality of air guide blades, and the air supply area of the air treatment device is adjusted by swinging the air guide blades.

[0079] The air guide blade in the adjusting assembly can move between the inner side of the air outlet and the outer side of the air outlet. In this way, the position of the air guide blade relative to the air outlet can be changed, and the interference phenomenon between the air guide blade and the air duct can be obviously improved. The deflection angle of the air guide blade is less affected by the air duct, and the deflection angle range of the air guide blade can be expanded, and the air supply coverage area of the air treatment equipment can be expanded.

[0080] In addition, by designing at least part of the air guide blade, a first curved portion is arranged on the blade body of the air guide blade, and the first curved portion is located on one side of the central axis of the blade body. The side away from the central axis of the first curved portion is the first air guide side of the air guide blade, and when the air treatment equipment is in the working state, the first air guide side is located on the outer side of the air outlet, and the first air guide side can guide the flow direction of the airflow blown out of the air outlet. By making the first air guide side have an included angle between the extension line of the first air guide side and the reference plane where the blade body is located, the first air guide side can change the air supply angle of the adjusting assembly, so that the air guide assembly is more flexible in adjusting the air supply area, and the air supply coverage area of the air treatment equipment is expanded.

[0081] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0082] The embodiments of the present application provide an air treatment equipment, which includes but is not limited to an air conditioning equipment, a humidifier, a dehumidifier, a ventilation equipment, a heat recovery ventilation system, an air purifier, a fresh air equipment and the like. In the embodiments of the present application, the air treatment equipment is taken as an air conditioning equipment for example, and is described. The air conditioning equipment can include a wall-mounted air conditioner, a stand-type air conditioner, a central air conditioner, a split-type air conditioner, a mobile air conditioner, a window air conditioner, a ducted air conditioner and the like.

[0083] The air treatment equipment is taken as a wall-mounted air conditioner for example and is described below.

[0084] Figure 1 A structural schematic diagram of an air treatment equipment provided by the embodiments of the present application is shown in FIG. 1. Referring to FIG. 1, Figure 1As shown, the air handling device 1 comprises a device body 10, the device body 10 having an air outlet 11 through which the air handling device 1 blows air outward. Taking a wall-mounted air conditioner as an example, the air handling device 1 is installed on a wall in a room, and the air outlet 11 can be arranged on the front side (a side surface facing away from the wall) of the device body 10 and close to the lower part. For example, the air outlet 11 can be arranged obliquely downward, and the air blowing area of the air handling device 1 is more appropriate.

[0085] The air outlet 11 of the device body 10 is provided with an air guide assembly 20, and the air blowing direction and the air blowing area of the air handling device 1 are adjusted through the air guide assembly 20 to realize flexible air blowing of the air handling device 1.

[0086] Figure 2 A perspective view of the air guide assembly from one perspective for the embodiments of the present application.

[0087] Figure 3 A perspective view of the air guide assembly from another perspective for the air guide assembly in Figure 2

[0088] Referring to Figure 2 As shown, the air guide assembly 20 comprises an adjusting assembly 100, and the adjusting assembly 100 is arranged in an 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. Moreover, 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 that the air blowing direction and the air blowing area of the device body 10 are adjusted through the adjusting assembly 100.

[0089] For ease of description, the embodiments define a base air duct wall 12 (see Figure 1 As shown), which is, for example, a side wall of the air duct close to the wall, and the adjusting assembly 100 can be mounted on the base air duct wall 12. The adjusting assembly 100 can be directly mounted on the base air duct wall 12, or can be mounted on the base air duct wall 12 through other support components.

[0090] 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 base air duct wall 12, and the plate surface of the bearing plate 110 can be parallel to the wall surface of the base air duct wall 12, for example. Moreover, the bearing plate 110 can extend along the length direction of the air outlet 11 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 the air guide blades 120 are movably connected to the bearing plate 110.

[0091] ​The bearing plate 110 is close to the base air duct wall 12, so as to facilitate the installation of the adjusting assembly 100 on the base air duct wall 12 through the bearing plate 110. The air guide blades 120 can be located on the side surface of the bearing plate 110 away from the base air duct wall 12, the air guide blades 120 are 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.

[0092] Referring to Figure 3 As shown in the drawings, 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.

[0093] The driving mechanism 200 is at least used for driving the air guide blades 120 of the adjusting assembly 100 to move, so that the air guide blades 120 change positions relative to the bearing plate 110. The included angle between the air guide blades 120 and a certain direction on the surface of the bearing plate 110 changes, and the air guide blades 120 are uniformly deflected towards one side of the air outlet 11, so as to adjust the air supply angle of the adjusting assembly 100.

[0094] 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 that the bearing plate 110 changes positions relative to the air outlet 11, and the distance between the bearing plate 110 and the base air duct wall 12 changes.

[0095] 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 out 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 guide blades 120 by the air duct can be weakened or even eliminated, and the deflection angle range of the air guide blades 120 can be further expanded.

[0096] In this way, the driving mechanism 200 not only drives the guide vane 120 to move relative to the bearing plate 110, but also drives the guide vane 120 to move together with the bearing plate 110, so that the driving mechanism 200 has more flexible driving modes for the adjustment assembly 100. In this way, the blowing angle of the air guide assembly 20 can be flexibly adjusted, the blowing area of the air guide assembly 20 is expanded, the blowing coverage area of the air guide assembly 20 is larger, and large-area area blowing 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.

[0097] In addition, the air guide assembly 20 can blow air towards more areas, and the adjustment accuracy of the air guide assembly 20 to the blowing area can be improved. Furthermore, by adjusting the blowing angle of the air guide assembly 20 through the driving mechanism 200, the blowing area of the air guide assembly 20 can be avoided from the activity area of the user, so as to avoid the discomfort or health problems caused by the direct blowing of cold air to the user. The blowing angle of the air guide assembly 20 can also be continuously changed by the driving mechanism 200, so as to avoid the long-time direct blowing of the air guide assembly 20 to a certain area, and improve the uniformity of the overall temperature in the room.

[0098] In this embodiment, the movement mode of the driving mechanism 200 driving the bearing plate 110 to move can be swinging, 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).

[0099] In this way, the driving mechanism 200 not only drives the guide vane 120 to move relative to the bearing plate 110, but also drives the guide vane 120 to move together with the bearing plate 110, so that the driving mechanism 200 has more flexible driving modes for the adjustment assembly 100. In this way, the blowing angle of the air guide assembly 20 can be flexibly adjusted, the blowing area of the air guide assembly 20 is expanded, the blowing coverage area of the air guide assembly 20 is larger, and large-area area blowing 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.

[0100] Of course, in other embodiments, the driving mechanism 200 can also drive the bearing plate 110 to move in a translational manner, and the length direction of the bearing plate 110 is always consistent with the length direction of the air outlet 11, and the bearing plate 110 is translated along the width direction of the bearing plate 110 on the base air duct wall 12. Further, the position of the bearing plate 110 relative to the air outlet 11 is changed. For example, the bearing plate 110 is moved from a position received in the air duct to a position towards the air outlet 11, for example, the bearing plate 110 is moved to the plane where the air outlet 11 is located, or even the bearing plate 110 is entirely extended out of the air outlet 11. Alternatively, the bearing plate 110 is moved from a position located in the plane where the air outlet 11 is located or outside the air outlet 11 to the air duct, so as to recycle the bearing plate 110 into the air duct.

[0101] In this way, the driving mechanism 200 can drive the bearing plate 110 to move towards the air outlet 11, so that the air guide blades 120 on the bearing plate 110 are closer to the air outlet 11, or even extended out of the air outlet 11. It can avoid the limitation of the air duct on the swing range of the air guide blades 120, and increase the deflection angle range of the air guide blades 120. Further, 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 duct can also avoid hindering the air supply of the air guide assembly 20, and avoid causing the air supply flow to be turbulent.

[0102] The following are all examples of driving the bearing plate 110 to swing on the base air duct wall 12 by the driving mechanism 200.

[0103] Referring to Figure 2 Or Figure 3 As for the air guiding manner 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 bearing plate 110 can be sequentially and spaced apart along the length direction of the bearing 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 of the air outlet 11, so as to guide the air flow to the left or right of the air outlet 11.

[0104] For example, each air guide blade 120 can be rotationally connected to the bearing plate 110. The rotation axis of each air guide blade 120 can be perpendicular to the plate surface of the bearing plate 110, and the blade surface of each air guide blade 120 can also be perpendicular to the plate surface of the bearing plate 110. The driving mechanism 200 can drive each air guide blade 120 to rotate along the rotation axis thereof, so as to realize the unified swinging of all the air guide blades 120 towards both ends of the left-right of the air outlet 11.

[0105] In some other embodiments, the air guiding assembly 20 can also be used to realize up-down air sweeping. In this case, the air guiding vanes 120 mounted on the carrier plate 110 can be arranged in sequence along the width direction of the carrier plate 110, and the air flow in the air duct is guided through the air guiding passages formed between two adjacent air guiding vanes 120. Each air guiding vane 120 can swing towards the two ends of the height direction (or the width direction) of the air outlet 11, or in other words, each air guiding vane 120 can swing towards the upper and lower ends of the air outlet 11, so as to guide the air flow to the upper or lower side of the air outlet 11.

[0106] For example, each air guiding vane 120 can be rotatably connected to the carrier plate 110. In this case, the rotation axis of each air guiding vane 120 can be parallel to the plate surface of the carrier plate 110, and the air guiding vane 120 can be connected to the carrier plate 110 through a support. For example, the two ends of the air guiding vane 120 in the extension direction are the rotation axes, the rotation axes of the two ends of the air guiding vane 120 are rotatably connected to the carrier plate 110 through the support, and the air guiding vane 120 and the plate surface of the carrier plate 110 have a gap. The driving mechanism 200 can drive each air guiding vane 120 to rotate along its rotation axis, so as to realize the swing of all air guiding vanes 120 towards the upper and lower ends of the air outlet 11 as a whole.

[0107] In some other embodiments, the air guiding assembly 20 can also be used to realize air sweeping in different directions. For example, the air guiding assembly 20 can realize both left-right air sweeping and up-down air sweeping. In other words, each air guiding vane 120 can swing towards the two ends (left and right ends) of the length direction of the air outlet 11, and each air guiding vane 120 can also swing towards the two ends (upper and lower ends) of the height direction of the air outlet 11.

[0108] For example, each air guiding vane 120 can be rotatably connected to the carrier plate 110. Since the air guiding assembly 20 can realize air sweeping in different directions, each air guiding vane 120 can have a rotation axis in different directions. For example, each air guiding vane 120 has a rotation axis perpendicular to the plate surface of the carrier plate 110, and each air guiding vane 120 has a rotation axis parallel to the plate surface of the carrier plate 110. All air guiding vanes 120 are mounted on the carrier plate 110 in the form of air guiding groups, each air guiding group includes a plurality of air guiding vanes 120, each air guiding group is rotatably connected to the carrier plate 110 through a rotation axis perpendicular to the plate surface of the carrier plate 110, and each air guiding vane 120 in each air guiding group is provided with a rotation axis parallel to the plate surface of the carrier plate 110.

[0109] The following is described by taking the air guiding assembly 20 for realizing left-right air sweeping as an example, each air guiding vane 120 is arranged in sequence along the length direction of the carrier plate 110, each air guiding vane 120 is rotatably connected to the carrier plate 110, and the rotation axis of each air guiding vane 120 is perpendicular to the plate surface of the carrier plate 110.

[0110] With reference to the drawings Figure 2 Or Figure 3 As an embodiment, the number of the adjustment assembly 100 in the air guide assembly 20 can be two. The two adjustment assemblies 100 can be arranged along the length direction of the air outlet 11. Under the driving of the driving mechanism 200, the air guide blades 120 of the two adjustment assemblies 100 can be deflected relative to the respective carrier plates 110, and the carrier plates 110 of the two adjustment assemblies 100 can also be deflected relative to the air outlet 11.

[0111] By arranging the two adjustment assemblies 100 along the length direction of the air outlet 11, the two adjustment assemblies 100 can respectively send air to different areas. The two adjustment 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 area of the air handling device 1.

[0112] For example, in the paper plane direction in the figure, the left adjustment assembly 100 is driven by the driving mechanism 200 to deflect the air guide blades 120 of the adjustment assembly 100 to the left, and the right adjustment assembly 100 is driven by the driving mechanism 200 to deflect the air guide blades 120 of the adjustment 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 carrier plates 110 of the left adjustment assembly 100 are driven by the driving mechanism 200 to deflect to the left, and the carrier plates 110 of the right adjustment assembly 100 are driven by the driving mechanism 200 to deflect to the right, the air sending area of the air guide assembly 20 as a whole will be further expanded.

[0113] In this way, the air conditioner has a larger air sending coverage area, 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 area 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 energy efficiency of the air conditioner is higher. In addition, the larger air sending coverage area 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.

[0114] As another embodiment, the air guide assembly 20 can also include only one adjustment assembly 100. Under the driving of the driving mechanism 200, the air guide blades 120 of the adjustment assembly 100 can be deflected relative to the carrier plate 110, and the carrier plate 110 can also be deflected relative to the air outlet 11. Thus, the one adjustment assembly 100 also has a large enough air sending area, which can meet the requirements of a general indoor space.

[0115] For example, when the air handling device 1 is applied in a living space, the indoor space is small, and only one adjusting assembly 100 can meet the indoor space requirements. Or, when the deflection angle range of the guide vane 120 of the adjusting assembly 100 is large, the deflection angle range of the bearing plate 110 is also large, and the guide vane 120 and the bearing plate 110 are superimposed to make the adjusting assembly 100 have a large air supply area, one adjusting assembly 100 can also meet the air supply requirements of a larger space, and then the air guide assembly 20 can only be provided with one adjusting assembly 100.

[0116] Of course, in other embodiments, the air guide assembly 20 can also include more than three adjusting assemblies 100, and each adjusting assembly 100 is sequentially arranged along the length direction of the air outlet 11. The driving mechanism 200 drives the guide vane 120 of each adjusting assembly 100 to deflect relative to the respective bearing plate 110, and the driving mechanism 200 also drives the bearing plate 110 of each adjusting assembly 100 to deflect relative to the air outlet 11.

[0117] For example, when the air handling device 1 is large in volume and has a long air outlet 11, a plurality of adjusting assemblies 100 can be sequentially and spaced apart along the length direction of the air outlet 11, and each adjusting assembly 100 maintains a suitable length to meet the stability and reliability requirements of the adjusting assembly 100. Or, when the air handling device 1 is applied in an office, a factory, or a larger space, a plurality of adjusting assemblies 100 can be provided to make the air guide assembly 20 have a larger air supply coverage area to meet the air supply requirements of a large space.

[0118] Referring to Figure 3 As shown, in order to realize that the driving mechanism 200 can drive each guide vane in the adjusting assembly to deflect relative to the bearing plate and drive the bearing plate to deflect relative to the air outlet. 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 drive each guide vane in the adjusting assembly to deflect relative to the bearing plate.

[0119] The first driving assembly 210 and the adjusting assembly can be one-to-one corresponding, 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, and each first driving assembly 210 is connected to each adjusting assembly. To drive the corresponding adjusting assembly to move through the first driving assembly 210.

[0120] Referring to Figure 3As shown, in some embodiments, when the air guiding assembly includes two or more adjustment assemblies, the driving mechanism 200 can further include at least one second driving assembly 220, which can be connected between two adjacent adjustment assemblies. At this time, the first driving assembly 210 can be used only to drive the air guiding blades to deflect relative to the carrier plate, and the carrier plates in the two adjustment assemblies connected on both sides of the second driving assembly 220 are driven to move by the second driving assembly 220.

[0121] When the air guiding assembly includes two adjustment assemblies, the driving mechanism 200 can be provided with only one second driving assembly 220, which is connected between the two adjustment assemblies, and the second driving assembly 220 can drive the carrier plates of the two adjustment assemblies to move relative to each other.

[0122] When the air guiding assembly includes three or more adjustment assemblies, a second driving assembly 220 can be provided between each two adjacent adjustment assemblies, and the second driving assembly 220 drives the carrier plates of the adjacent adjustment assemblies to move relative to each other. Alternatively, only one second driving assembly 220 can be provided between two adjacent adjustment assemblies, and the other adjacent adjustment assemblies are connected through a transmission structure, and the driving force of the second driving assembly 220 is transmitted through the transmission structure to realize the movement of the carrier plates of all the adjustment assemblies.

[0123] By providing the first driving assembly 210 to drive the air guiding blades and the second driving assembly 220 to drive the carrier plates, the first driving assembly 210 and the second driving assembly 220 respectively drive one moving object, and the driving mode is relatively simple, and the structural design of the first driving assembly 210 and the second driving assembly 220 can be relatively simplified. In this way, the design difficulty of the first driving assembly 210 and the second driving assembly 220 is relatively low, and the design cost of the two can be reduced. Moreover, the first driving assembly 210 and the second driving assembly 220 do not affect each other, and even if one of them fails and cannot work, the other one can still work, and the probability that the air guiding blades and the carrier plates cannot move is relatively low, and the operation reliability of the air guiding assembly is higher.

[0124] In other embodiments, the driving mechanism 200 can include only the first driving assembly 210, which is used to drive the air guiding blades of the adjustment assemblies to deflect relative to the carrier plate and drive the carrier plate to deflect relative to the air outlet. At this time, no matter how many adjustment assemblies the air guiding assembly includes, only one first driving assembly 210 needs to be provided for each adjustment assembly.

[0125] When the air guide assembly includes two or more adjustment assemblies, each adjustment assembly is independently driven by the first driving assembly 210, and there is no linkage relationship between the adjustment assemblies, and the air supply area of each adjustment assembly can be independently adjusted. In this way, the air handling device can be suitable for different indoor layouts and use requirements, and users can flexibly adjust the air supply area of the two adjustment assemblies according to actual conditions. In order to meet the needs of different environments for different air supply areas, so that the airflow blown by the air handling device is fully and effectively utilized, and waste is avoided.

[0126] As for the architectural design of the first driving assembly 210, referring to Figure 3 When the first driving assembly 210 only drives the movement of each air guide vane on the carrier plate, the first driving assembly 210 can only include one driving motor 201. The output shaft of the driving motor 201 can be directly transmitted to the air guide vane, or the output shaft of the driving motor 201 can be transmitted to the air guide vane after speed reduction and torque increase through a speed reduction gear.

[0127] When the first driving assembly 210 simultaneously drives the air guide vane and the carrier plate, as an embodiment, the first driving assembly 210 can be provided with two driving motors 201, one of which is transmitted to the air guide vane, and the other is transmitted to the carrier plate. In this way, the two driving motors 201 do not affect each other, and even if one of them fails and cannot work, the other one can still work, and the probability that the air guide vane and the carrier plate cannot move is low, and the operation reliability of the adjustment assembly is higher.

[0128] When the first driving assembly 210 simultaneously drives the air guide vane and the carrier plate, 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 transmitted to the air guide vane, and the output shaft of the driving motor 201 is transmitted to the carrier plate through a transmission structure, so as to simultaneously drive the air guide vane and the carrier plate to move through one driving motor 201. For example, the transmission structure can be a gear set, the driving motor 201 directly drives the air guide vane to rotate, and the driving motor 201 drives the carrier plate to swing through the gear set.

[0129] As for the architectural design of the second driving assembly 220, referring to 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 adjustment assemblies. The driving motor 201 drives the transmission member 221 to move, and the transmission member 221 drives the two carrier plates to move relative to each other.

[0130] Exemplarily, the transmission member 221 can include a push-pull rod 2211 and two connecting rods 2212. The drive 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. The other end of each of the two connecting rods 2212 is connected to the two bearing plates respectively. The drive motor 201 drives the push-pull rod 2211 to move in the plane direction of the bearing plate, so that the push-pull rod 2211 drives the two connecting rods 2212 to move relatively, and in turn, drives the two bearing plates to swing relatively.

[0131] Figure 4 A disassembled structure diagram of the adjusting assembly provided by the embodiment of the present application is shown in Figure 4 In order to realize the driving of all the guide vanes on the bearing plate by the first driving assembly 210, the adjusting assembly can further be provided with a linkage member 130. All the guide vanes are connected with 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.

[0132] The first driving assembly 210 can be connected with one of the guide vanes provided on the bearing plate, for example, the first driving assembly 210 is connected with the guide vane located at one end in the length direction of the bearing plate. The first driving assembly 210 drives the guide vane to rotate, and the guide vane drives the linkage member 130 connected therewith to move. In turn, all the guide vanes are driven to swing synchronously through the linkage member 130.

[0133] Alternatively, the first driving assembly 210 can also be connected with the linkage member 130, for example, the first driving assembly 210 is connected at the part of the linkage member 130 between the two guide vanes. The first driving assembly 210 drives the linkage member 130 to move, and the linkage member 130 drives all the guide vanes to swing synchronously.

[0134] Continuously referring to Figure 4 The linkage member 130 can be arranged in the bearing plate. In this way, the linkage member 130 is connected with all the guide vanes. Moreover, the linkage member 130 is shielded in the bearing plate, so that the appearance of the adjusting assembly is more simple and concise. In addition, the linkage member 130 does not occupy extra separate space, and has no influence on the volume of the adjusting assembly, which is beneficial to the thinning of the adjusting assembly.

[0135] In order to install the linkage member 130 in the bearing plate 110 and facilitate the connection of the linkage member 130 with each guide vane, 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 member 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. The first driving assembly 210 passes through the bottom plate 112 to be connected with the guide vanes or the linkage member 130.

[0136] like Figure 4 As shown, as an example, the linkage 130 can be a connecting rod 130a, which extends along the extension direction of the support plate 110 and is connected to all the guide vanes 120. The drive motor 201 of the first drive assembly 210 can drive one of the guide vanes 120 to rotate, and the guide vane 120 drives the connecting rod 130a to reciprocate with a small swing amplitude. Through the swing and reciprocating motion of the connecting rod 130a, all the guide vanes 120 are driven to swing. Alternatively, the output shaft of the drive motor 201 is connected to the connecting rod 130a, and the drive motor 201 rotates to drive the connecting rod 130a to reciprocate with a small swing amplitude, thereby driving all the guide vanes 120 to swing.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] Figure 5 Another exploded view of the adjustment assembly is provided for embodiments of the present application. Referring to FIG. 1C, the air guide vane 120 includes a vane body 121, which is the main structure of the air guide vane 120. The vane bodies 121 of adjacent air guide vanes 120 form air guide channels therebetween to guide the airflow blown out of the air outlet 11. The air guide vane 120 is driven to move by the first driving assembly 210, which changes the orientation of the vane body 121 of the air guide vane 120, and in turn changes the air supply direction of the adjustment assembly 100. Figure 5 As shown, the air guide vane 120 includes a vane body 121, which is the main structure of the air guide vane 120. The vane bodies 121 of adjacent air guide vanes 120 form air guide channels therebetween to guide the airflow blown out of the air outlet 11. The air guide vane 120 is driven to move by the first driving assembly 210, which changes the orientation of the vane body 121 of the air guide vane 120, and in turn changes the air supply direction of the adjustment assembly 100.

[0141] The thickness of the vane body 121 can be between 2mm and 3mm. In this way, the vane body 121 has a certain thickness to meet the processability requirements of the vane body 121 and to ensure the required structural strength of the vane body 121. At the same time, the thickness of the vane body 121 is relatively small, and the vane body 121 occupies a small space, and there is enough spacing between adjacent vanes, which can smoothly guide the airflow in the air duct and avoid affecting the air outlet of the air handling equipment 1.

[0142] For example, the thickness of the vane 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.

[0143] When the air guide vane 120 is rotatably connected to the carrier plate 110, the air guide vane 120 can further include a rotating shaft 122. The rotating shaft 122 is connected to the vane body 121, and the rotating shaft 122 can be integrally formed on the vane body 121 to form an integrally formed air guide vane 120. The rotating shaft 122 can be connected to one end of the vane body 121 facing the carrier plate 110, and the rotating shaft 122 is rotatably connected to the carrier plate 110, and the vane body 121 rotates around the rotating shaft 122.

[0144] For example, the rotating shaft 122 can be located on the central axis of the vane body 121. In this way, the air guide vane 120 has good force balance, and the stability and reliability of the air guide vane 120 during rotation are better. Moreover, the width of the vane 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 vane 120, and the spacing between adjacent vanes can be designed according to the width of the vane body 121, so that the air guide vanes 120 are uniformly spaced. In addition, the air guide vane 120 can also be better applied in a 360° rotation scenario, the movement range of the air guide vane 120 is minimized, and the required movement space of the air guide vane 120 is also minimized, which can reduce the occupied space of the air guide assembly 20, and is conducive to the miniaturization of the air handling equipment 1.

[0145] 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). The disc structure can rotate in the mounting groove to realize the rotation of the guide vane 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 vane body 121). In this way, the disc structure does not protrude on the surface of the bearing plate 110, which helps to reduce the wind resistance of the adjustment assembly 100. Moreover, the flatness of the adjustment assembly 100 is better, and it is more beautiful.

[0146] Figure 6 For Figure 2 the front view of the air guide assembly in the air handling device. Figure 7 For Figure 6 the partial enlarged view of the air guide vane at position A in FIG. 6. In combination with Figure 6 and Figure 7 shown in FIGS. 6 and 7, the shape of the guide vane 120 in the adjustment assembly 100 is also designed in the embodiment. The guide vane 120 further adjusts the air supply direction, and enhances the flexibility of the adjustment assembly 100 in adjusting the air supply area, so as to further expand the air supply coverage area of the air guide assembly 20.

[0147] For the convenience of description, the relative two sides of the vane body 121 of the guide vane 120 are defined as the first air guide side 1211 and the second air guide side 1212, respectively. The first air guide side 1211 and the second air guide side 1212 are located on the two sides of the central axis of the vane body 121. When the air handling device 1 is in the working state, and the guide vane 120 is in the state of opening the air outlet 11, one of the first air guide side 1211 and the second air guide side 1212 of the vane body 121 is located at the inner position of the air outlet 11, and the other is located at the outer position of the air outlet 11.

[0148] Specifically, the vane body 121 of at least part of the guide vane 120 in the adjustment assembly 100 is provided with a curved surface shape. For these curved surface shaped vane bodies 121, the central axis of the vane body 121 is taken as a boundary line. On one side of the central axis of the vane body 121, the first curved portion 1213 is formed. The first air guide side 1211 is on the side of the first curved portion 1213 away from the central axis of the vane body 121.

[0149] By designing the vane body 121 on one side of the central axis as the first curved portion 1213, the first curved portion 1213 causes the first air guide side 1211 to be inclined to one side of the vane body 121. With the reference plane A of the vane body 121 as a reference, the extension direction of the first air guide side 1211 deviates from the reference plane A. There is an included angle α between the extension line of the first air guide side 1211 and the reference plane A (see FIG. 7). Figure 7As shown).

[0150] The reference plane A of the blade body 121 is a normal projection plane of the blade body 121, which is formed by normal projection of the blade body 121. 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. It can be understood that when the blade body 121 is in a planar shape, the plane where the blade body 121 is located is the reference plane A.

[0151] When the air handling device 1 is in a working state, the air guide channels are formed between the blade bodies 121 of the adjacent air guide vanes 120, and the airflow at the air outlet 11 is blown to the outside along the air guide channels. Since one side of the blade body 121 is the first curved portion 1213, the first curved portion 1213 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.

[0152] The so-called Coanda effect, also known as wall attachment or Coanda effect, is a phenomenon in fluid mechanics. Specifically, during the flow of fluid (water flow or air flow), the fluid will deviate from the original flow direction and flow along the convex surface of the object. When there is surface friction (or fluid viscosity) between the fluid and the surface of the object it flows through, as long as the curvature is not large, the fluid will flow along the surface of the object.

[0153] Therefore, when the airflow in the air duct flows to the air outlet 11, it flows through the surface of the first curved portion 1213, and the airflow rubs against the surface of the first curved portion 1213. The flow direction of the airflow can be changed so that the airflow flows along the surface of the first curved portion 1213. Ultimately, when the airflow passes through the blade body 121 and is blown to the outside, it can flow along the extension direction of the first air guide side 1211. That is, the extension direction of the first air guide side 1211 can be considered as the air supply direction of the air guide vane 120.

[0154] In this way, the flow direction of the airflow blown out of the air outlet 11 by the first air guide side 1211 is guided so that the airflow flows along the extension direction of the first air guide side 1211. The first air guide side 1211 has an included angle between the extension line and the reference plane A where the blade body 121 is located, which is equivalent to changing the flow direction of the airflow that would originally flow along the extension direction of the reference plane A. In turn, the air supply angle of the adjustment assembly 100 can be changed, making the adjustment of the air supply area by the air guide assembly 20 more flexible, and further expanding the air supply coverage area of the air handling device 1.

[0155] When the air handling unit 1 is in operation, the first curved portion 1213 in the blade body 121 can be located outside the air outlet 11, and the first air guide side 1211 is the side where the airflow exits the air guide channel. In this way, the airflow flows along the surface of the first curved portion 1213, and when the airflow is blown to the outside, it can flow along the extension direction of the first air guide side 1211, thereby changing the air delivery direction of the regulating component 100.

[0156] Furthermore, in order to expand the air delivery area of ​​the adjustment component 100, the first curved portion 1213 can cause the first air guide side 1211 to deflect towards the same side of the air outlet 11. (Refer to...) Figure 7 As shown, with the guide vane 120 in a vertical position as a reference, when the guide vane 120 is perpendicular to the plane of the air outlet 11, the extension line of the first guide side 1211 can extend to the same side of the air outlet 11. Taking the position of the guide vane 120 closer to the left side of the length direction of the air outlet 11 as an example, the first guide side 1211 can be tilted to the left side of the air outlet 11. When the guide vane 120 is perpendicular to the plane of the air outlet 11, the extension line of the first guide side 1211 can extend to the left side of the air outlet 11.

[0157] To ensure the regulating assembly 100 has a large air supply coverage area, the guide vanes 120 are typically directed to the same side as the air outlet 11. For example, the guide vanes 120 on the left side of the length direction of the air outlet 11 direct airflow to the left side of the air outlet 11, and the guide vanes 120 on the right side of the length direction of the air outlet 11 direct airflow to the right side of the air outlet 11. By extending the extension line of the first guide side 1211 to the same side of the air outlet 11, the air supply deflection angle of the guide vanes 120 can be further increased when the guide vanes 120 direct airflow to the same side of the air outlet 11. This, in turn, expands the air supply area of ​​the regulating assembly 100. The airflow guidance of the aforementioned guide vanes to the same side of the air outlet is illustrated by the following two examples: For the guide vane 120 located on the left side of the length direction of the air outlet 11, when the guide vane 120 guides airflow to the left side of the air outlet 11, the first guide side 1211 can further deflect the airflow angle of the guide vane 120 to the left side of the air outlet 11. For the guide vane 120 located on the right side of the length direction of the air outlet 11, when the guide vane 120 guides airflow to the right side of the air outlet 11, the first guide side 1211 can further deflect the airflow angle of the guide vane 120 to the right side of the air outlet 11. This increases the airflow deflection angle of the air guide assembly 20 to both sides of the air outlet 11, expanding the airflow area and coverage of the air guide assembly 20.

[0158] Of course, in some embodiments, the first curved portion 1213 in the blade body 121 can also be located at the inner side of the air outlet 11 when the air handling device 1 is in operation, and the first air guide side 1211 is the side through which the air flow enters the air guide channel. In this way, the flow direction of the air flow can be changed when the air flow enters the air guide channel. After the air flow flows along the surface of the first curved portion 1213 in the air guide channel, the flow direction of the air flow is changed. Further, the flow direction of the air flow after flowing out of the air guide vane 120 is also changed, so as to change the air supply direction of the adjustment assembly 100.

[0159] At this time, in order to expand the air supply area of the adjustment assembly 100, the first curved portion 1213 can also cause the first air guide side 1211 to be inclined to the same side of the air outlet 11. When the air guide vane 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the first air guide side 1211 can extend to the same side of the air outlet 11. In this way, when the air guide vane 120 needs to guide air to the same side of the air outlet 11, the extension line of the first air guide side 1211 of the air guide vane 120 is perpendicular to the plane where the air outlet 11 is located, or the extension line of the first air guide side 1211 of the air guide vane 120 is inclined to the other side of the air outlet 11, so as to ensure that the air flow is inclined to the same side of the air outlet 11 when the air flow flows out of the air outlet 11.

[0160] For example, taking the air guide vane 120 close to the left side of the length direction of the air outlet 11 as an example, when the air guide vane 120 guides air to the left side of the air outlet 11, the extension line of the first air guide side 1211 of the air guide vane 120 located at the inner side of the air outlet 11 can be perpendicular to the plane where the air outlet 11 is located, or the extension line of the first air guide side 1211 of the air guide vane 120 extends to the inner side of the air outlet 11 and is inclined to the right side of the air outlet 11. In this way, the air guide vane 120 is inclined to the left side of the air outlet 11 as a whole, and air can be guided to the left side of the air outlet 11.

[0161] In this way, taking the center line of the length direction of the air outlet 11 as a boundary, when the air handling device 1 is in operation, the air guide vane 120 located at the left side of the air outlet 11 can be deflected to the left (for example, the air guide vane 120 in the adjustment assembly 100 located at the left side of the two adjustment assemblies 100 is deflected to the left), and the air supply angle and the air supply area of the air supply to the left side of the air outlet 11 are expanded through the air guide effect of the first curved portion 1213. At the same time, the air guide vane 120 located at the right side of the air outlet 11 can be deflected to the right (for example, the air guide vane 120 in the adjustment assembly 100 located at the right side of the two adjustment assemblies 100 is deflected to the right), and the air supply angle and the air supply area of the air supply to the right side of the air outlet 11 are expanded through the air guide effect of the first curved portion 1213. Thus, the air supply coverage area of the air handling device 1 is significantly expanded.

[0162] Alternatively, the air guide vanes 120 on both sides of the air outlet 11 can be deflected to the left (for example, the air guide vanes 120 in both adjustment assemblies 100 are deflected to the left). At this time, the angles of deflection of all the air guide vanes 120 on the left side of the air outlet to the left side of the air outlet are increased. In addition, the carrier plates 110 in the adjustment assembly 100 on the right side can be deflected to the left to increase the angles of deflection of the air guide vanes 120 thereon to the left. Even the carrier plates 110 in the adjustment assembly 100 on the left side can be deflected to the left to increase the angles of deflection of the air guide vanes 120 thereon to the left. Thus, the angles of deflection of the air handling device 1 to the left are obviously increased.

[0163] 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 angles of deflection 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 carrier plates 110 in the adjustment assembly 100 on the left side can be deflected to the right to increase the angles of deflection of the air guide vanes 120 thereon to the right. Even the carrier plates 110 in the adjustment assembly 100 on the right side can be deflected to the right to increase the angles of deflection of the air guide vanes 120 thereon to the right. Thus, the angles of deflection of the air handling device 1 to the right are obviously increased. The following are described by way of example with the air handling device 1 in the working state, the first curved portion 1213 in the blade body 121 of the air guide vane 120 being located on the outside of the air outlet 11, and the first air guide side 1211 being inclined to the same side of the air outlet 11.

[0164] For example, the angle between the extension line of the first air guide side 1211 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 angle between the extension line of the first air guide side 1211 and the perpendicular line of the air outlet 11 (a line perpendicular to the plane of the air outlet 11) is 30°, so that 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 angle between the extension line of the first air guide side 1211 and the perpendicular line of the air outlet 11 is 45°, so that the deflection angle of the air guide vane 120 to the left is 45°.

[0165] In this way, when the air guide vane 120 guides air to the same side of the air outlet 11, the blade 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 angle between the first air guide side 1211 of the blade body 121 and the reference plane A is increased, so that the first air guide side 1211 is deflected to the same side of the air outlet 11 by a larger angle. The deflection angle of the blade body 121 is increased, the deflection area of the adjustment assembly 100 is larger, and the deflection coverage is wider.

[0166] Meanwhile, on the basis that the blowing angle of the air guide blade 120 is fixed, the deflection angle of the blade body 121 is the required blowing angle minus the included angle between the first air guide side 1211 of the blade body 121 and the reference plane A, and the required deflection angle of the blade body 121 is smaller. In this way, the rotation angle of the driving motor 201 driving the rotation of the blade body 121 is smaller, the energy consumption of the driving motor 201 is less, and it is beneficial to save the energy consumption of the adjustment assembly 100 and reduce the overall energy consumption of the air treatment equipment 1.

[0167] Continuing to refer to Figure 7 In some embodiments, on the basis that one side of the blade body 121 is designed as the first curved portion 1213, the other side of the blade body 121 can also be designed as the second curved portion 1214. That is, both sides of the central axis of the blade body 121 are designed as curved portions. Among them, the second curved portion 1214 is away from one side of the central axis of the blade body 121, that is, the second air guide side 1212 of the blade body 121. The extension direction of the second air guide side 1212 also deviates from the reference plane A, and the included angle between the extension line of the second air guide side 1212 and the reference plane A.

[0168] Taking the vertical state of the air guide blade 120 as a reference, the air guide blade 120 is perpendicular to the plane where the air outlet 11 is located, and when the first air guide side 1211 is located on the outside of the air outlet 11, the extension line of the first air guide side 1211 extends to the same side of the air outlet 11. At this time, the second air guide side 1212 is located on the inside of the air outlet 11, and the extension line of the second air guide side 1212 extends to the opposite side of the air outlet 11. Still taking the left side of the air guide blade 120 close to the air outlet 11 as an example, when the air guide blade 120 is perpendicular to the plane where the air outlet 11 is located, the extension line of the first air guide side 1211 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 guide side 1212 located on the inside of the air outlet 11 can extend to the right side of the air outlet 11.

[0169] In this way, for the air guide blade 120 capable of rotating 360°, when the air guide blade 120 is rotated to the second air guide side 1212 of the blade body 121 located on the outside of the air outlet 11, the second air guide side 1212 also deviates to the left side of the air outlet 11, which is the same as when the first air guide side 1211 is located on the outside of the air outlet 11. In this way, the air guide blade 120 can also be rotated to the second air guide side 1212 located on the outside of the air outlet 11, and the air guide blade 120 guides the airflow blown out of the air outlet 11 by the second air guide side 1212, and increases the blowing deflection angle of the air guide blade 120 by the second air guide side 1212.

[0170] When the air handling device 1 is in operation, either the first air guiding side 1211 of the air guiding blade 120 or the second air guiding side 1212 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 1211 or the second air guiding side 1212. 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 1211 and the second air guiding side 1212 of the air guiding blade 120 do not need to be intentionally 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.

[0171] For example, the bending shape of the second bending part 1214 can be completely consistent with the bending shape of the first bending part 1213, 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.

[0172] In this way, whether the first air guiding side 1211 is located on the outside of the air outlet 11 or the second air guiding side 1212 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.

[0173] In other embodiments, only one side of the blade body 121 can be designed as the first bending part 1213, 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.

[0174] When one side of the blade body 121 is the first curved portion 1213 and the other side is the flat portion, the first air guiding side 1211 of the air guiding blade 120 can be directed to the outside of the air outlet 11 when the air guiding blade 120 is installed. And the rotation angle range of the air guiding blade 120 can be controlled so that the first curved portion 1213 of the blade body 121 is always located on the outside of the air outlet 11, and the flat portion of the blade body 121 is always located on the inside of the air outlet 11. The first air guiding side 1211 is used to guide the air flow of the air outlet, and the blowing angle of the air guiding blade 120 is changed.

[0175] Of course, as mentioned earlier, the flat portion of the blade body 121 can be located on the outside of the air outlet 11, and the first curved portion 1213 of the blade body 121 can be located on the inside of the air outlet 11, and the first curved portion 1213 can be used to adjust the flow direction of the air flow entering the air guiding channel. Thus, the blowing angle of the air guiding blade 120 is changed. Here, it is not repeated.

[0176] As for the overall design of all air guiding blades 120 in the entire adjustment assembly 100, all air guiding blades 120 can be designed as curved shapes. In this way, the first air guiding side 1211 of all air guiding blades 120 can increase the blowing deflection angle of the air guiding blade 120. The blowing angle of the entire adjustment assembly 100 can be changed, so that the deflection angle of the blowing area of the entire adjustment assembly 100 is increased.

[0177] 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 curved air guiding blades 120 can increase the blowing deflection angle of the corresponding area of the adjustment assembly 100. And the remaining flat air guiding blades 120 can maintain the original blowing deflection angle of the corresponding area of the adjustment assembly 100.

[0178] 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 adjustment assembly 100 is increased. In this way, the blowing area of the adjustment assembly 100 is larger, the blowing coverage is wider, and the air outlet is more gentle.

[0179] In the adjustment assembly 100, whether only part of the air guiding blades 120 are designed as curved shapes or all air guiding blades 120 are designed as curved shapes, all air guiding blades 120 with curved shapes can have consistent shapes. In this way, the curved air guiding blades 120 have consistent blowing adjustment effects on the corresponding areas of the adjustment assembly 100.

[0180] Alternatively, along the direction of the end portion close to the air outlet 11, that is, from the center of the air outlet 11 to the end portion of the air outlet 11, the angle between the extension line of the first air guide side 1211 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 portion of the air outlet 11, the air supply deflection angle of the adjustment assembly 100 gradually increases, the air supply area of the adjustment 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.

[0181] Referring to Figure 6 For example, the air guide assembly 20 has two adjustment assemblies 100, when the air handling device 1 is working, in the adjustment assembly 100 located on the left side of the length direction of the air outlet 11, the first air guide side 1211 of the air guide blade 120 in the curved surface shape is inclined to the left side of the air outlet 11. In the adjustment assembly 100 located on the right side of the length direction of the air outlet 11, the first air guide side 1211 of the air guide blade 120 in the curved surface 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 plate 110 of the two adjustment assemblies 100 relatively swings outward, which can further expand the air supply coverage of the air guide assembly 20.

[0182] The air guide blade 120 in the curved surface shape will be described in detail below, and the first curved portion 1213 of the air guide blade 120 will be described in detail. It can be understood that when the other side of the air guide blade 120 is designed as a second curved portion 1214, the second curved portion 1214 has the same characteristics as the first curved portion 1213.

[0183] Referring to Figure 7 As shown in the figure, the angle range of the angle α between the extension line of the first air guide side 1211 of the air guide blade 120 and the reference plane A can be 5°-45°. Taking the plane direction perpendicular to the air outlet 11 as a reference, when the angle α between the extension line of the first air guide side 1211 and the reference plane A is 5°, the air supply direction of the air guide blade 120 is deflected by 5° to the same side of the air outlet 11; the air guide blade 120 continues to deflect by 85° to the same side of the air outlet 11, that is, the extension line of the first air guide side 1211 is parallel to the plane direction of the air outlet 11. When the angle α between the extension line of the first air guide side 1211 and the reference plane A is 45°, the air supply direction of the air guide blade 120 is deflected by 45° to the same side of the air outlet 11; the air guide blade 120 continues to deflect by 45° to the same side of the air outlet 11, that is, the extension line of the first air guide side 1211 is parallel to the plane direction of the air outlet 11.

[0184] In this way, the air guide blade 120 only needs to rotate in a small angle range, so that the air guide blade 120 has an air supply area with a large angle range. The air guide blade 120 can flexibly adjust the air supply angle and change the air supply area of the adjustment assembly 100. Moreover, the angle between the extension line of the first air guide side 1211 and the reference plane A is not too large, the bending degree of the first bending part 1213 is appropriate, and the air guide blade 120 does not hinder the flow of the air flow. The air resistance of the whole adjustment assembly 100 is small, which does not affect the air supply amount of the air handling device 1.

[0185] For example, the angle a between the extension line of the first air guide side 1211 and the reference plane A thereof can be between 25° and 45°. By making the angle a between the extension line of the first air guide side 1211 and the reference plane A thereof greater than or equal to 25°, when the air guide blade 120 is perpendicular to the plane direction of the air outlet 11, the deflection angle of the air supply direction of the air guide blade 120 deflects to the same side of the air outlet 11 and is greater than or equal to 25°. The first air guide side 1211 can significantly increase the air supply deflection angle of the air guide blade 120, and can better expand the air supply area of the adjustment assembly 100.

[0186] For example, the angle a between the extension line of the first air guide side 1211 and the reference plane A thereof can be 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, etc.

[0187] Continuing to refer to Figure 7 The first bending part 1213 of the blade body 121 can be a smooth bending part, and the bending shape of the whole first bending part 1213 is relatively gentle. The first bending part 1213 can make the air flow smoothly along the surface thereof, change the flow direction of the air flow, and not hinder the flow of the air flow. The air flow smoothly flows out of the air guide channel along the first bending part 1213, so that the air handling device 1 stably blows the air flow to the outside.

[0188] Moreover, the first bending part 1213 can only have one bending vertex 12131. That is, the first bending part 1213 is bent only once to one side of the thickness direction of the blade body 121. In order to realize the deflection of the first air guide side 1211 to the same side of the air outlet 11, the first bending part 1213 can be slightly convex to the other side of the air outlet 11. In this way, the first bending part 1213 is avoided from forming a wavy surface with continuous concave-convex, so as to avoid the first bending part 1213 changing the flow direction of the air flow multiple times, affecting the air supply deflection angle of the air guide blade 120, and ensuring the adjustment effect of the first bending part 1213 on the air supply deflection angle of the air guide blade 120. It can also avoid the air flow being turbulent when flowing through the first bending part 1213, so as to ensure that the air flow can smoothly and orderly flow out of the air guide blade 120, so as to avoid the loss of the air supply amount of the air handling device 1.

[0189] When the first curved portion 1213 has only one curved vertex 12131, the extension line of the first air guiding side 1211 extends to one side of the reference plane A, and the curved vertex 12131 can be located on the other side of the reference plane A. Taking the air guiding vane 120 close to the left side of the length direction of the air outlet 11 as an example, specifically taking the air guiding vane 120 perpendicular to the plane where the air outlet 11 is located as a reference datum, the extension of the first air guiding side 1211 of the air guiding vane 120 can extend to the left side of the reference plane A, and the curved vertex 12131 can be located on the right side of the reference plane A.

[0190] In this way, the extension line of the first air guiding side 1211 and the curved vertex 12131 of the first curved portion 1213 are avoided to be located on the same side of the reference plane A, and the first curved portion 1213 is avoided to be excessively bent to one side of the air guiding vane 120. The air guiding vane 120 as a whole is flat, and the bending degree is small, so that the air resistance generated is small. In the long-term use process of the air guiding vane 120, the air guiding vane 120 is less compressed by the airflow, and the reliability of the air guiding vane 120 is higher, and the service life is longer. Moreover, the air guiding vane 120 as a whole is still flat, and occupies a smaller space, so that the air guiding vane 120 is convenient to arrange on the bearing plate 110.

[0191] For example, the first air guiding side 1211 of the first curved portion 1213 away from the central axis of the vane body 121 can have a center line in the thickness direction located on the reference plane A. In this way, the bending shape of the first curved portion 1213 is constrained, and the first curved portion 1213 is limited within a smaller bending range, so that the smoothness of the vane body 121 is higher, the fluid resistance is smaller, and the high-efficiency air supply requirement of the air handling equipment 1 is better met.

[0192] When the other side of the vane body 121 is provided with the second curved portion 1214, and the second curved portion 1214 has the same shape as the first curved portion 1213, or the other side of the vane body 121 is provided with a straight portion, the center line of the second air guiding side 1212 of the vane body 121 in the thickness direction can also be located on the reference plane A. In this way, both sides of the vane body 121 are located on the reference plane A thereof, and the overall design of the vane body 121 tends to be planar, the shape is more regular, the air guiding effect is good, and the stability and reliability are high.

[0193] Figure 8 Another perspective structural view of the air guiding assembly provided by the embodiment of the present application is shown. Figure 9 For Figure 8 A partial enlarged view of the air guiding assembly in the air guiding assembly is shown. Figure 9 The structure of the part where one of the air guiding vanes 120 on the adjusting assembly 100 is shown.

[0194] Referring toFigure 8 and Figure 9 As shown in FIG. 12, the blade body 121 of the air guide blade 120 can also be provided with a plurality of air outlet holes 1215 penetrating through the two side surfaces of the blade body 121 in the thickness direction. When the blade body 121 is in the curved shape as described above, the blade body 121 can be provided with a plurality of air outlet holes 1215. When the blade body 121 is in the planar shape, the blade body 121 can also be provided with a plurality of air outlet holes 1215. The air outlet holes 1215 can be provided on all the blade bodies 121 of the adjustment assembly 100.

[0195] When the air handling equipment 1 is in the working state, the air flow blown in the air duct can flow outwards through the air outlet holes 1215 on the blade body 121 by providing a plurality of air outlet holes 1215 on the blade body 121.

[0196] Specifically, when the air guide blade 120 is in the open state, the air guide blade 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 blades 120. At this time, the air flow blown in the air duct will flow outwards along the air guide channel, and a part of the air flow can flow outwards through the air outlet holes 1215 on the blade body 121. In this way, the air outlet effect of the air handling equipment 1 is improved by using the air outlet holes 1215 on the blade body 121.

[0197] When the air handling equipment 1 blows air outwards through the adjustment assembly 100, in addition to the first air flow flowing outwards along the air guide channel, the second air flow flowing outwards through the air outlet holes 1215 will also be generated, and the flow direction of the second air flow is different from that of the first air flow. Under the counterflow action of the second air flow on the first air flow, the flow rate of the first air flow can be slowed down, and strong wind can be avoided from being blown out of the air outlet 11, so that the air outlet effect of the air handling equipment 1 is more gentle, and the use comfort of the air handling equipment 1 is improved.

[0198] It should be noted that the air outlet holes 1215 provided on the blade body 121 are small in aperture, and the air flow in the air duct will still preferentially flow outwards through the air guide channel between the adjacent air guide blades 120. Thus, most of the air flow in the air duct will flow out through the air guide channel between the adjacent air guide blades 120, and only a small part of the air flow will flow out through the air outlet holes 1215. This small part of the air flow flowing out through the air outlet holes 1215 can have a good counterflow mixing effect, which can weaken the air outlet flow rate. At the same time, it will not have too much influence on the air outlet direction and air outlet area of the adjustment assembly 100 as a whole, and the air outlet adjustment effect of the adjustment assembly 100 can be ensured.

[0199] 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 1215 on the vane body 121. Since the air outlet hole 1215 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 1215 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.

[0200] For example, when the air handling device 1 is in the heating mode, the guide vane 120 can be in the closed state, and only the air outlet hole 1215 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 1215 on the vane body 121. Moreover, by outputting the hot air outward only through the air outlet hole 1215 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.

[0201] The plurality of air outlet holes 1215 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 1215 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 1215 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.

[0202] For example, the air outlet holes 1215 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 1215), a plurality of rows of air outlet holes 1215 are arranged in sequence, and each row of air outlet holes 1215 includes a plurality of air outlet holes 1215 arranged in sequence along the width direction of the vane body 121. Adjacent two rows of air outlet holes 1215 can be staggered, and each air outlet hole 1215 in one row can correspond to the adjacent two air outlet holes 1215 in another row.

[0203] The area of the air outlet holes 1215 on the blade body 121 can be 45%-85% of the total area of the blade body 121, that is, the opening rate of the blade body 121 can be 45%-85%. In this way, the blade body 121 has sufficient opening area to ensure the flow area of the blade body 121 itself, and the airflow flowing outwards through the air outlet holes 1215 of the blade body 121 reaches a certain flow rate, which can achieve an effective air supply softening effect.

[0204] 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 1215, and the air supply flow rate through the air outlet holes 1215 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.

[0205] Figure 10 A cross-sectional view of the air guide blade is provided for the embodiment of the present application. Referring to FIG. 12, Figure 10 As shown in the figure, the air guide blade 120 is cut off in the middle region of a row of air outlet holes 1215 along the width direction of the air guide blade 120. On the basis of the air outlet holes 1215 formed on the blade body 121, the extension direction of the air outlet holes 1215 is designed in this embodiment. The air outlet holes 1215 do not extend along the thickness direction of the blade body 121, but the extension direction of the air outlet holes 1215 is designed to be inclined.

[0206] For ease of description, the two side surfaces of the blade body 121 in the thickness direction are defined as the first surface 1216 and the second surface 1217, respectively. Among them, the first surface 1216 is the side where the extension direction of the extension line of the first air guide side 1211 is located. That is, when the air guide blade 120 is in an open state and the air guide blade 120 is inclined and deflected to the same side of the air outlet 11, the first surface 1216 of the blade body 121 faces the inner side of the air outlet 11, and the second surface 1217 of the blade body 121 faces the outer side of the air outlet 11 (see FIG. 12). Figure 6

[0207] ​Taking the air guide blade 120 on the left side of the length direction close to the air outlet 11 as an example, when the air guide blade 120 is in the open state and the air guide blade 120 is inclined and deflected to the left side of the air outlet 11, the air supply angle of the air guide blade 120 is deflected to the left side of the air outlet 11. At this time, the first air guide side 1211 of the blade body 121 faces the outside of the air outlet 11, the second air guide side 1212 of the blade body 121 faces the inside of the air outlet 11, the first surface 1216 of the blade body 121 faces the inside of the air outlet 11, and the second surface 1217 of the blade body 121 faces the outside of the air outlet 11. The extension line of the first air guide side 1211 extends to the left side of the air outlet 11, that is, the extension line of the first air guide side 1211 extends to the side where the first surface 1216 is located.

[0208] In this embodiment, the air outlet hole 1215 can be inclined to the side where the first air guide side 1211 of the blade body 121 is located from the first surface 1216 of the blade body 121 to the second surface 1217 of the blade body 121. That is, the central axis of the air outlet hole 1215 extends obliquely to the first air guide side 1211, the angle between the central axis of the air outlet hole 1215 and the reference plane A of the blade body 121 on the side where the first air guide side 1211 is located is less than 90°, and the angle between the central axis of the air outlet hole 1215 and the reference plane A of the blade body 121 on the side where the second air guide side 1212 is located is greater than 90°.

[0209] In this way, when the air guide blade 120 is in the open state, the angle between the extension direction of the air outlet hole 1215 and the side of the blade body 121 close to the outside of the air outlet 11 in the air supply direction of the adjustment assembly 100 is an acute angle, and the air outlet direction of the air outlet hole 1215 tends to be the air guide direction of the blade body 121. The direction difference between the flow direction of the first air flow flowing out of the air guide channel between the adjacent air guide blades 120 and the flow direction of the second air flow flowing out of the air outlet hole 1215 is less than 90°.

[0210] When the air guide blade 120 is deflected to the same side of the air outlet 11, and the first air flow flowing out of the air guide channel between the adjacent air guide blades 120 is deflected to the same side of the air outlet 11, the second air flow flowing out of the air outlet hole 1215 of the blade body 121 is not obviously deflected to the same side of the air outlet 11, but the second air flow will not be obviously deflected 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 adjustment assembly 100 on the air supply direction and the air supply area can be ensured.

[0211] 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 airflow flowing out of the air guide channel between the adjacent air guide blades 120 deflects to the left side of the air outlet 11, and the flow direction of the second airflow flowing out of the air outlet hole 1215 of the blade body 121 can be approximately toward the front of the air outlet 11, or the flow direction of the second airflow can slightly deflect to the left side of the air outlet 11.

[0212] Therefore, by tilting the air outlet hole 1215 on the blade body 121 toward the first air guide side 1211 from the first surface 1216 to the second surface 1217 of the blade body 121, the second airflow flowing out of the air outlet hole 1215 can not only collide with the first airflow 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 airflow to the air supply direction of the adjustment assembly 100 as a whole can be weakened, and the air supply adjustment accuracy of the adjustment assembly 100 can be ensured.

[0213] Specifically, the angle range of the included angle between the extension direction of the air outlet hole 1215 on the blade body 121 and the reference plane A is 30°-60°.

[0214] Taking the deflection angle of the blade body 121 deflecting to the same side of the air outlet 11 as 45° as a reference, the included angle between the blade body 121 and the vertical direction of the air outlet 11 (perpendicular to the plane of the air outlet 11) is 45°, and the included 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 is relatively obviously deflected to the same side of the air outlet 11. The deflection angle is more appropriate to judge whether the air outlet direction of the air outlet hole 1215 is appropriate or not.

[0215] Taking the air guide blade 120 close to the left side of the air outlet 11 as an example, when the included angle between the extension direction of the air outlet hole 1215 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 out of the air outlet hole 1215 deflects 15 degrees to the right side of the air outlet hole 1215. When the included angle between the extension direction of the air outlet hole 1215 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 out of the air outlet hole 1215 deflects 15 degrees to the left side of the air outlet hole 1215.

[0216] Therefore, the smaller the angle between the extending direction of the air outlet hole 1215 and the reference plane A, the more the air outlet direction of the air outlet hole 1215 tends to be close to the overall air supply direction of the adjustment assembly 100. When the deflection angle of the blade body 121 to the same side of the air outlet 11 is greater than 45°, it indicates that the adjustment assembly 100 has a more obvious effect on guiding the air to the same side of the air outlet 11. Therefore, by designing the angle between the extending direction of the air outlet hole 1215 and the reference plane A to be less than or equal to 60°, when the adjustment assembly 100 guides the air to the same side of the air outlet 11, the airflow blown by the air outlet hole 1215 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.

[0217] For example, the angle between the extending direction of the air outlet hole 1215 on the blade body 121 and the reference plane A is in the range of 40°-50°. Taking the air guiding blade 120 close to the left side of the air outlet 11 as an example, when the angle between the extending direction of the air outlet hole 1215 and the reference plane A is 50°, the deflection angle of the blade body 121 to the left side of the air outlet 11 is 45°, and the second airflow blown by the air outlet hole 1215 is deflected to the right side of the air outlet hole 1215 by 5 degrees. When the angle between the extending direction of the air outlet hole 1215 and the reference plane A is 30°, the deflection angle of the blade body 121 to the left side of the air outlet 11 is 45°, and the second airflow blown by the air outlet hole 1215 is deflected to the left side of the air outlet hole 1215 by 15 degrees.

[0218] In this way, when the air supply angle of the adjustment assembly 100 is obviously deflected to the same side of the air outlet 11, the second airflow blown from the air outlet hole 1215 of the blade body 121 is approximately blown to the front of the air outlet 11, or the second airflow blown from the air outlet hole 1215 is also deflected to the same side of the air outlet 11. In this way, the air outlet hole 1215 can avoid affecting the overall air supply direction of the adjustment assembly 100. Moreover, the inclination of the air outlet hole 1215 is not too large, which facilitates the machining of the air outlet hole 1215 on the blade body 121. In addition, the air outlet hole 1215 occupies a moderate space in the planar direction of the blade body 121, and a sufficient number of air outlet holes 1215 can be machined on the blade body 121 to ensure the air supply amount of the air outlet hole 1215 of the blade body 121.

[0219] For example, the angle between the extending direction of the air outlet hole 1215 on the blade body 121 and the reference plane A is 45°. Taking the air deflector blade 120 close to the left side of the air outlet 11 as an example, when the angle between the extending direction of the air outlet hole 1215 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 by the air outlet hole 1215 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 by the air outlet hole 1215 is also deflected to the same side of the air outlet 11.

[0220] As for the shape of the air outlet hole 1215 on the blade body 121, the present embodiment does not make specific limitations thereon. The air outlet hole 1215 can have a relatively regular shape, and stress concentration phenomenon can be avoided. For example, the cross-sectional shape of the air outlet hole 1215 can be circular, elliptical or regular polygonal. When the cross-sectional shape of the air outlet hole 1215 is regular polygonal, the cross-sectional shape of the air outlet hole 1215 is, for example, regular pentagonal, regular hexagonal, regular octagonal, etc.

[0221] The air outlet hole 1215 with a suitable size can be machined on the blade body 121 according to the size of the blade body 121. Taking the air outlet hole 1215 as a circular hole as an example, the hole diameter of the air outlet hole 1215 can be between 4mm-9mm. In this way, the air outlet hole 1215 has sufficient cross-sectional area, and the air outlet hole 1215 meets the blowing requirement, ensuring that the air outlet hole 1215 on the blade body 121 has a certain blowing amount. Moreover, the cross-sectional area of the air outlet hole 1215 is not too large, and a sufficient number of air outlet holes 1215 can be provided on the blade body 121, avoiding that the air outlet hole 1215 affects the structural strength and reliability of the blade body 121.

[0222] For example, the hole diameter of the air outlet hole 1215 can be 4.5mm, 5.0mm, 5.5mm, 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, etc.
