Description
Technical Field
[0001] This specification relates to the field of refrigeration technology, and in particular to a swing blade assembly and an air conditioner. Background Art
[0002] Air conditioners often operate in high humidity environments during the summer. If the blades are at a small angle and the air flow around them is not ideal, condensation can easily form on the blades. A common solution is to use control code to prevent the blades from being at a small angle for extended periods. However, this increases control costs and utility costs.
[0003] By adopting this outlet swing blade, the wall attachment effect can be fully utilized, so that when the swing blade is at a small angle, the airflow outside the swing blade flows along the surface of the swing blade, avoiding condensation on the swing blade. Summary of the Invention
[0004] In order to overcome the problems existing in the related art, this specification provides a swing blade assembly and an air conditioner.
[0005] According to a first aspect of the embodiments of this specification, a swing blade assembly is provided, comprising: a support assembly and a swing blade; the support assembly is used to secure the swing blade to an air conditioner housing; the swing blade comprises a windward surface and a wind guide surface disposed opposite each other along the thickness direction, the windward surface being connected to the support assembly; the swing blade comprises a connected swing blade head and a swing blade guide portion; the wind guide surface is closer to the outside of the air conditioner housing relative to the windward surface; and both ends of the swing blade head smoothly connect the windward surface located at the swing blade guide portion and the wind guide surface located at the position of the swing blade guide portion. The swing blade assembly is mounted at the air outlet of the air conditioner, with the windward surface close to the inside of the air conditioner and the wind guide surface away from the inside of the air conditioner. The air outlet of the air conditioner is guided by the windward surface and the wind guide surface and blown in a direction below the horizontal plane, thereby reducing condensation water generated on the swing blade after backflow. The head of the swing blade smoothly connects the windward surface and the wind guide surface, which improves the wall attachment effect and makes the airflow blown out from the top of the swing blade by the air conditioner easier to move downward. In this way, since the outlet air temperature outside the air conditioner is lower than the ambient temperature, the outlet air flow density is greater than the ambient air density. The airflow descends along the wind guide surface away from the swing blade, thereby reducing the relatively high temperature air that contacts the outer surface of the swing blade, reducing the occurrence of condensation, and thus reducing the appearance of condensed water.
[0006] Furthermore, the swing blade is rotatable between a first working position and a second working position; when the swing blade is in the first working position, the absolute value of the angle between the line connecting the end of the swing blade head away from the swing blade guide and the end of the swing blade guide away from the swing blade head and the vertical direction is angle A; when the swing blade is in the second working position, the absolute value of the angle between the line connecting the end of the swing blade head away from the swing blade guide and the end of the swing blade guide away from the swing blade head and the vertical direction is angle B; the absolute value of the difference between A and B is greater than 90° and less than 150°. The swing blade can rotate about one end of the support assembly to switch between different working positions, and the greater the absolute value of the angle between the line connecting the end of the swing blade head away from the swing blade guide and the end of the swing blade guide away from the swing blade head and the vertical direction, the closer the air outlet direction is to being parallel to the extension direction of the swing blade, the more significant the wall adhesion effect is, and the less condensation water is generated.
[0007] Furthermore, the angle between the tangent line of the end of the blade head connected to the windward surface of the blade guide portion and the horizontal plane is a first angle, and the angle between the tangent line of the end of the blade head connected to the windward surface of the blade guide portion and the horizontal plane is a second angle; the first angle gradually decreases to the second angle from the end of the blade head connected to the windward surface of the blade guide portion to the end of the blade head connected to the windward surface of the blade guide portion. The blade head is smoothly connected to both the windward surface and the wind-guiding surface, which is specifically reflected in that the angle between the tangent line of the blade head and the horizontal plane changes gradually, rather than suddenly, from the end of the blade head connected to the windward surface to the end of the blade head connected to the wind-guiding surface.
[0008] Furthermore, the swing blade can be rotated to a first working position. When the swing blade is in the first working position, when the absolute value of the angle between the line connecting the end of the swing blade head away from the swing blade guide and the end of the swing blade guide away from the swing blade head and the vertical direction is 15°-45°, the first angle is greater than 180° and the second angle is less than 0°. The intersection of the swing blade head and the windward surface and the wind guide surface has a smooth transition. When the first angle and the second angle meet the above ranges, the process of airflow flowing along the windward surface through the swing blade head to the wind guide surface is smoother, reducing the proportion of airflow flowing out along the tangential direction of the swing blade head and reducing the generation of condensed water.
[0009] Furthermore, the curvature of the pendulum blade head is a first curvature, and the curvature is greater than 10m -1 , and less than 650m -1 The curvature is maintained at 650m. -1And below can ensure that the change rate of the swing blade head can also maintain the airflow at the outlet within the range where the wall effect can take effect, improve the wall effect, reduce the contact of hot air with the relatively cold swing blades, and reduce the generation of condensation water.
[0010] Furthermore, the swing blade includes a swing blade tail portion remote from one end of the swing blade head, the swing blade tail portion being smoothly connected to the windward surface of the swing blade guide portion and / or the wind guide surface of the swing blade guide portion. The swing blade tail portion is smoothly connected to the windward surface and the wind guide surface, directing airflow exiting the air conditioner from below the swing blade away from the swing blade. This avoids the generation of vortices in the swing blade tail region due to a sudden change in the slope of the swing blade tail portion, prevents airflow from accumulating at the swing blade tail portion to generate condensed water, and reduces the dripping of condensed water droplets at the swing blade tail portion.
[0011] Furthermore, the swing blade can be rotated to a first working position. When the swing blade is in the first working position, the tangent angle of the end of the swing blade guide portion connected to the swing blade head is a third angle, and the tangent angle of the end of the swing blade guide portion not connected to the swing blade head is a fourth angle. When the absolute value of the angle between the direction of the line connecting the end of the swing blade head away from the swing blade tail and the end of the swing blade tail away from the swing blade head and the vertical direction is 15°-45°, the third angle is less than 0°, and the fourth angle is greater than 0°. The angle range between the tangents at both ends of the wind guide surface and the horizontal plane changes the airflow from the negative angle direction at the junction of the wind guide surface and the swing blade head to the positive direction at the junction of the wind guide surface and the swing blade tail through the wall attachment effect, so that the airflow is away from the swing blade. At the same time, since the airflow flows along the wind guide surface, no low-pressure area will appear in the area near the wind guide surface, so that the hot air in the environment will not contact the wind guide surface to produce condensed water, thereby avoiding the occurrence of condensation.
[0012] Furthermore, the structure located at the blade guide portion and the wind guide surface located at the tail of the blade and the blade head is used as a second guide unit; the curvature of the second guide unit is a second curvature, and the second curvature is greater than 5m -1 , and less than 650m -1 The curvature of the blade head is maintained at 650m -1 And below can ensure that the rate of change of the blade head can also keep the airflow at the outlet within the range where the wall effect can take effect, and the curvature of the wind guide surface is kept at 5m -1 -650m -1 , which can improve the wall effect, reduce the contact of hot air with relatively cool swing blades, and reduce the generation of condensation water.
[0013] Furthermore, the windward surface is provided with a plurality of vertical reinforcing ribs that extend through the swing blades and extend parallel to the direction of airflow. The reinforcing ribs provide structural strength to the swing blades and reduce lateral airflow on the windward surface of the swing blades, preventing airflow from flowing out from both ends of the swing blades' length, thereby making the airflow more uniform and easier to guide.
[0014] According to a second aspect of the embodiments of this specification, an air conditioner is provided, comprising the above-mentioned swing blade assembly and an air conditioner casing on which the swing blade assembly is installed.
[0015] The technical solutions provided by the embodiments of this specification may have the following beneficial effects:
[0016] The airflow at the outlet is made to flow out along the surface of the swing blade through the wall attachment effect, and the smooth connection between the swing blade head and the windward surface and the wind guide surface ensures that the airflow can be blown out along the surface of the swing blade, thereby achieving the downward guidance of the outlet airflow, reducing the high-temperature air flowing onto the swing blade, and achieving the effect of reducing the generation of condensation water.
[0017] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-Figure 2As shown, in a first aspect, the present application provides a swing blade assembly 2, comprising a support assembly 10 and a swing blade 11. The support assembly 10 is mounted on an air conditioner housing 1. The swing blade 11 includes a windward surface 20 and a wind guide surface 21 disposed opposite each other along the thickness direction, as well as a connected swing blade head 22 and a swing blade guide 23. The support assembly 10 is used to secure the swing blade 11 to the air conditioner housing 1. The swing blade assembly 2 is mounted at the air conditioner outlet, with the windward surface 20 close to the inside of the air conditioner and the wind guide surface 21 away from the inside. Air from the air conditioner is guided by the windward surface 20 and the wind guide surface 21 and blown in a direction below the horizontal plane, thereby reducing condensation formed on the swing blade after backflow. The windward surface 20 is connected to the support assembly 10, and the wind guide surface 21 is closer to the outside of the air conditioner housing 1 relative to the windward surface 20. The ends of the swing blade head 22 smoothly connect the windward surface 20 at the location of the swing blade guide 23 and the wind guide surface 21 at the location of the swing blade guide 23. The swing blade head 22 smoothly connects the windward surface 20 and the wind guide surface 21, which improves the wall attachment effect and makes the airflow blown out from the top of the swing blade 11 by the air conditioner easier to move downward. In this way, outside the air conditioner, since the air outlet temperature is lower than the ambient temperature, the air outlet airflow density is greater than the ambient air density, and the airflow descends along the wind guide surface 21 away from the swing blade 11, thereby reducing the relatively high temperature air that contacts the outer surface of the swing blade 11, reducing the occurrence of condensation, and further reducing the appearance of condensed water.
[0024] like Figure 1 and Figure 3 As shown, the swing blade 11 can rotate between a first working position 30 and a second working position 31. The swing blade 11 can rotate about one end of the support assembly 10 to switch between different working positions, and provide the air outlet angle required by the user through the different working positions. When the swing blade 11 is in the first working position 30, the angle between the line connecting the end of the swing blade head 22 away from the swing blade guide 23 and the end of the swing blade guide 23 away from the swing blade head 22 and the vertical direction is the smallest, making it most likely that condensation will form on the air guide surface 21 of the swing blade 11. The larger the absolute value of the angle between the line connecting the end of the swing blade head 22 away from the swing blade guide 23 and the end of the swing blade guide 23 away from the swing blade head 22 and the vertical direction, the closer the air outlet direction is to being parallel to the extension direction of the swing blade 11, the more significant the wall adhesion effect is, and the less condensation will be generated.
[0025] When the swing blade 11 is in the first working position 30, the absolute value of the angle between the line connecting the end of the swing blade head 22 away from the swing blade guide 23 and the end of the swing blade guide 23 away from the swing blade head 22 and the vertical direction is angle A. When the swing blade 11 is in the second working position 31, the absolute value of the angle between the line connecting the end of the swing blade head 22 away from the swing blade guide 23 and the end of the swing blade guide 23 away from the swing blade head 22 and the vertical direction is angle B. The absolute value of the difference between A and B is greater than 90° and less than 150°. The absolute value of the difference between A and B represents the working position range of the swing blade 11, and the swing blade 11 can rotate within this range. In this embodiment, the absolute value of the difference between A and B is 120°, which is divided into five levels. In the first level, the swing blade 11 is in the first position, and in the fifth level, the swing blade 11 is in the second position. The second to fourth levels are evenly spaced 30° apart from each other.
[0026] The angle between the tangent line at the end of the blade head 22 connected to the windward surface 20 of the blade guide 23 and the horizontal is a first angle 40, and the angle between the tangent line at the end of the blade head 22 connected to the windward surface 21 of the blade guide 23 is a second angle 41. Specifically, the first angle 40 is the angle of the tangent line along the first quadrant, the second quadrant, and the third quadrant to the end of the blade head 22 connected to the windward surface 20 of the blade guide 23, and the second angle 41 is the angle of the tangent line along the fourth direction to the end of the blade head 22 connected to the windward surface 21 of the blade guide 23. From the end of the blade head 22 connected to the windward surface 20 of the blade guide 23 to the end of the blade head 22 connected to the windward surface 21 of the blade guide 23, the first angle 40 gradually decreases to the second angle 41. The first angle 40 is gradually reduced to the second angle 41 to achieve a smooth transition of the blade head 22, allowing airflow to flow out along the surface curve of the blade head 22. The blade head 22 is smoothly connected to both the windward surface 20 and the wind guide surface 21. This is specifically reflected in the fact that the angle between the tangent line of the blade head 22 and the horizontal plane changes gradually, rather than suddenly, from the end of the blade head 22 connected to the windward surface 20 to the end of the blade head 22 connected to the wind guide surface 21.
[0027] The swing blade 11 can be rotated to a first working position 30. When the swing blade 11 is in the first working position 30, when the absolute value of the angle between the line connecting the end of the swing blade head 22 away from the swing blade guide 23 and the end of the swing blade guide 23 away from the swing blade head 22 and the vertical direction is 15°-45°, the first angle 40 is greater than 180°, and the second angle 41 is less than 0°. The intersection of the swing blade head 22, the windward surface 20, and the wind guide surface 21 has a smooth transition. When the first angle 40 and the second angle 41 meet the above ranges, the process of the airflow flowing along the windward surface 20 through the swing blade head 22 to the wind guide surface 21 is smoother, reducing the proportion of airflow flowing out in the tangential direction of the swing blade head 22 and reducing the generation of condensed water.
[0028] The curvature of the blade head 22 is a first curvature 50, which is greater than 10m-1 and less than 650m -1 The curvature is maintained at 650m. -1 The following can ensure that the change rate of the blade head 22 can also keep the airflow at the outlet within the range where the wall effect can take effect, improve the wall effect, reduce the contact of hot air with the relatively cool swing blade 11, and reduce the generation of condensation water. In this embodiment, the curvature range of the blade head 22 is 12m -1 ~625m -1 .
[0029] The swing blade 11 includes a swing blade tail portion 24 at one end away from the swing blade head portion 22. The swing blade tail portion 24 is smoothly connected to the windward surface 20 of the swing blade guide portion 23 and the wind guide surface 21 of the swing blade guide portion 23. The swing blade tail portion 24 is smoothly connected to the windward surface 20 and the wind guide surface 21, directing airflow from the air conditioner exiting from below the swing blade 11 away from the swing blade 11. This prevents vortices from forming in the swing blade tail portion 24 due to a sudden change in the slope of the swing blade 11 tail portion, prevents airflow from condensing at the swing blade tail portion 24, and reduces the chance of condensation from dripping from the swing blade tail portion 24.
[0030] The swing blade 11 can be rotated to a first working position 30. When the swing blade 11 is located in the first working position 30, the tangent angle of the end of the swing blade guide 23 connected to the swing blade head 22 is a third angle 42, and the tangent angle of the end of the swing blade guide 23 not connected to the swing blade head 22 is a fourth angle 43. When the absolute value of the angle between the direction of the line connecting the end of the swing blade head 22 away from the swing blade tail 24 and the end of the swing blade tail 24 away from the swing blade head 22 and the vertical direction is 15°-45°, the third angle 42 is less than 0°, and the fourth angle 43 is greater than 0°. The angle range between the tangents at both ends of the wind guide surface 21 and the horizontal plane changes the airflow from the negative angle direction at the junction of the wind guide surface 21 and the swing blade head 22 to the positive direction at the junction of the wind guide surface 21 and the swing blade tail 24 through the wall attachment effect, so that the airflow moves away from the swing blade. At the same time, since the airflow flows along the wind guide surface 21, no low-pressure area will appear in the area near the wind guide surface 21, and the hot air in the environment will not come into contact with the wind guide surface 21 to produce condensed water, thereby avoiding the occurrence of condensation.
[0031] The windward surface 20 located at the blade guide portion 23 is used as the first guide unit, and the structure of the wind guide surface 21 located at the blade guide portion 23 and the blade tail portion 24 and the blade head portion 22 is used as the second guide unit. The curvature of the second guide unit is a second curvature 51, and the second curvature 51 is greater than 5m -1 , and less than 650m -1 The first guide unit is used to guide the airflow leaving the air conditioner from below the swing blade 11, and the second guide unit is used to guide the airflow leaving the air conditioner from above the swing blade 11. The curvature of the swing blade head 22 is maintained at 650m -1 The following can ensure that the rate of change of the blade head 22 can also keep the airflow at the outlet within the range where the wall effect can take effect, and the curvature of the wind guide surface 21 is kept at 5m -1 -650m -1 , which can improve the wall effect, reduce the contact of hot air with the relatively cool swing blades 11, and reduce the generation of condensed water. In this embodiment, the curvature range of the wind guide surface 21 is 6m -1 ~625m -1 .
[0032] The windward surface 20 is vertically provided with a plurality of reinforcing ribs 25, which extend through the swinging blade 11. The ribs 25 provide structural strength to the swinging blade 11. The ribs 25 extend parallel to the direction of the airflow. By aligning the ribs 25 with the airflow, the ribs 25 block the original lateral airflow, reducing lateral airflow on the windward surface 20 of the swinging blade 11 and preventing airflow from flowing out from both ends of the length of the swinging blade 11. This results in a more uniform and easier-to-direct airflow.
[0033] A second aspect of the present application provides an air conditioner, comprising the above-mentioned swing blade assembly 2 and an air conditioner housing 1 on which the swing blade assembly 2 is installed, wherein the air conditioner housing 1 comprises an air conditioner housing 1 on which the swing blade assembly 2 is installed.
[0034] It should be understood that the present description is not limited to the exact structure that has been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present description is limited only by the appended claims.
[0035] The above description is only a preferred embodiment of this specification and is not intended to limit this specification. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this specification should be included in the scope of protection of this specification.
