Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments. In the following description, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
The present embodiment relates to a wind sweeping blade, including a wind sweeping portion 1;
the air sweeping part 1 comprises an air sweeping surface 2 for guiding airflow to flow, a flow distribution structure 3 is arranged on the air sweeping surface 2, and the flow distribution structure 3 is a block-shaped or columnar bulge;
the flow dividing structure 3 enables the air flow passing through the wind-sweeping surface 2 to be attenuated.
The flow dividing structure 3 is protrudingly arranged on the wind sweeping surface 2, so that the airflow can be obstructed by the flow dividing structure 3 when flowing through the wind sweeping surface 2. The large air flow flowing along the wind-sweeping surface 2 is divided into a plurality of even finer air-dividing flows by the air-dividing structure 3. In addition, because the flow dividing structure 3 is a block-shaped or column-shaped protrusion, compared with a protrusion in a strip shape or other shapes extending on the wind sweeping surface 2, the block-shaped or column-shaped protrusion does not have a guiding function of guiding the airflow to flow, so that after the airflow impacts and separates from the flow dividing structure 3, the flow direction of part of the airflow is changed due to the blocking function of the flow dividing structure 3, and part of the airflow flows in a turbulent flow manner, so that multiple strands of the airflow has more varied air outlet directions. By integrating the two points, the flow dividing structure 3 can simultaneously refine the air outlet flow and adjust the air outlet direction, so that the air outlet flow of the air conditioner flowing in a large strand is prevented from directly blowing the human body, and the comfort of the air conditioner is effectively improved.
The term "block" as used herein means that the protrusions have dimensions in three mutually orthogonal directions, and the surface of the block structure may have a regular planar shape, for example, the block structure may have a cubic shape, a rectangular parallelepiped shape, or another polygonal shape, or the surface of the block structure may have a regular or irregular curved shape, for example, a spherical shape, a curved polygonal shape, or the block structure may have an irregular structure, for example, a granular structure. The columnar shape in the present invention means that the size of the protrusion along a certain direction is significantly large, and for example, the protrusion may be a cylindrical shape, a square column shape, or a columnar structure with an irregular bottom surface, where the bottom surface is one side end surface of the main body structure.
As a preferred embodiment, when the flow dividing structure 3 is a columnar projection, the columnar projection is arranged perpendicular to the wind sweeping surface 2. More specifically, one side end face of the cylinder protrusion is connected to the wind sweeping surface 2, and the other side end face of the main body protrusion extends in a direction away from the wind sweeping surface 2.
As a preferred embodiment, the flow dividing structure 3 includes:
the connecting part is of a cylindrical structure, and one end of the cylindrical structure is connected and arranged on the wind sweeping surface 2;
the head is of a hemispherical structure, and the plane of the hemispherical structure is connected with the other end of the cylindrical structure into a whole. The plane of the hemispherical structure and the hemispherical surface jointly form the outer wall of the hemispherical structure.
In this preferred embodiment, the surfaces of the flow dividing structure 3 that are in direct contact with the airflow are curved surfaces (i.e., the side wall of the cylindrical structure that is curved and the hemispherical surface of the hemispherical structure), and when the airflow flows through the flow dividing structure 3, the airflow flows along the curved surfaces, which is beneficial to changing the flow direction of the airflow to a greater extent, so that the difference between the flow directions of adjacent airflows is increased, and the airflow in different flow directions interacts with each other, thereby increasing the proportion occupied by the airflow flowing in a turbulent flow manner, and thus being beneficial to further enhancing the ability of the flow dividing structure 3 to refine the airflow and reduce the impact force of the airflow, and improving the comfort of the air outlet of the air conditioner.
Preferably, the diameter of the hemispherical structure is equal to the diameter of the cylindrical structure. More specifically, the two same diameters enable the plane of the hemispherical structure and the other end wall surface of the cylindrical structure to be connected in a complete superposition manner, and further preferably, the diameter of the hemispherical structure is 5-6mm, namely, the diameter of the cylindrical structure is also 5-6mm, so as to achieve good effects of thinning the airflow and changing the airflow direction.
As a better implementation mode, the number of the flow dividing structures 3 is multiple, the flow dividing structures 3 are dispersedly arranged at the wind sweeping surface 2, and the effects of dividing and refining large airflow and improving the comfort of the wind outlet can be achieved by increasing the number of the flow dividing structures 3 and arranging the flow dividing structures in a regular or irregular manner.
As a preferred embodiment, a plurality of the flow dividing structures 3 are arranged in a direction perpendicular to the incoming flow direction of the airflow. It should be noted that the direction of the incoming airflow in the present invention refers to a direction from a region where the airflow contacts first to a region where the airflow contacts later when the airflow passes through the wind sweeping surface 2. A plurality of the shunting structures 3 are arranged along the direction perpendicular to the incoming flow of the airflow, so that each shunting structure 3 is not shielded by other shunting structures 3, the function of refining the airflow is fully exerted, the least number of the shunting structures 3 is favorably utilized, and the optimal effect of refining the airflow is achieved. Preferably, the distance between two adjacent shunting structures 3 is 3-5mm, so as to achieve a better shunting and thinning effect.
As a preferred embodiment, the flow dividing structure 3 comprises a first end connected with the wind sweeping surface 2 and a second end as a free end, the distance from the second end to the first end is 8-10mm, which is a preferred distance set according to the usual pitch of the wind sweeping blades in the existing air conditioner, and in practical application, the distance from the second end to the first end can be increased with the increase of the pitch of the wind sweeping blades or decreased with the decrease of the pitch of the wind sweeping blades.
As a preferred embodiment, the wind sweeping part 1 is a sheet structure, and includes a first wind sweeping surface and a second wind sweeping surface which are oppositely arranged, and the first wind sweeping surface and the second wind sweeping surface constitute the wind sweeping surface 2; the flow distribution structure 3 is arranged on the first wind sweeping surface and/or the second wind sweeping surface. That is, the flow dividing structure 3 may be disposed on either one of the first wind-sweeping surface and the second wind-sweeping surface, or may be disposed on both the first wind-sweeping surface and the second wind-sweeping surface, and the manner of simultaneous disposition has a stronger refining capability for the airflow, and the effect of improving the comfort of the air conditioner is more significant, but this may lead to an increase in complexity of the structure and an increase in manufacturing and installation costs.
The specific implementation mode also relates to a wind sweeping mechanism which comprises at least one wind sweeping blade; when the number of the wind sweeping blades is more than two, the more than two wind sweeping blades are arranged in parallel at intervals. The air sweeping mechanism can provide refined air outlet flow while sweeping air according to needs.
