FIG. 1 is a schematic view of a yaw deck shown from a first perspective in accordance with an exemplary embodiment of the present application; fig. 2 is a schematic view of a yaw blade according to an embodiment of the present application from a second perspective.
Referring to fig. 1-2, the present embodiment provides a horizontal swing blade for being horizontally connected in an air outlet, including a first protrusion 10 located above a first reference plane S1 and a second protrusion 20 located below the first reference plane S1; wherein the first reference plane S1 is parallel to the horizontal plane, the horizontal swing blade is located at two ends of the first reference plane S1 for connecting with the air outlet, and the first protruding part 10 and the second protruding part 20 are configured to: the pressure after the part air-out of air outlet passes through first bellying 10 and the pressure inequality after the second bellying 20 of another part air-out of air outlet.
Specifically, the horizontal swing blade of this embodiment may be disposed at an air outlet of the floor air conditioner internal unit, and the horizontal swing blade is horizontally connected in the air outlet. As shown in fig. 1, the yaw blade includes a first convex portion 10 located above the first reference plane S1 and a second convex portion 20 located below the first reference plane S1, with a plane S1 parallel to the horizontal plane as the first reference plane. The shape of the first convex portion 10 and the shape of the second convex portion 20 may be determined as needed, for example, the first convex portion 10 may have a hemispherical shape, a cylindrical shape, a prismatic shape, or the like; the second boss 20 may also have a hemispherical shape, a cylindrical shape, a prismatic shape, or the like. The shape of the first convex portion 10 and the shape of the second convex portion 20 may be the same or different, and may be determined as needed.

In this embodiment, the first protruding portion 10 and the second protruding portion 20 are symmetrically arranged with respect to the first reference surface S1, when the horizontal swing blade swings up and down with respect to the first reference surface S1, the pressure of the air outlet at one side of the air outlet after passing through the first protruding portion 10 is not equal to the pressure of the air outlet at the other side of the air outlet after passing through the second protruding portion 20, and a pressure difference is formed at one side of the horizontal swing blade away from the air outlet, so that the wind sensation of the air outlet at one side of the horizontal swing blade away from the air outlet is softer and close to the wind sensation of natural wind.
Further, the distance of the yaw blade from the first reference plane S1 is configured to: the sizes of the two ends of the horizontal swinging blade on the first reference surface S1 are gradually increased towards the middle of the horizontal swinging blade on the first reference surface S1; the width of the yaw blade within the first reference plane S1 is configured to: the size of the swing blade gradually increases from the two ends of the swing blade on the first reference surface S1 to the middle of the swing blade on the first reference surface S1.
Through the arrangement, the horizontal swinging blade is wider at the middle position of the air outlet with larger air quantity and faster air speed, and is narrower at the edge position of the air outlet with smaller air quantity and slower air speed, so that the air speed and the air quantity of the air outlet at each position after passing through the horizontal swinging blade tend to be consistent, and the use experience of a user is favorably improved.
Optionally, the first protrusion 10 and the second protrusion 20 in the yaw blade of the present embodiment are each in a quadrangular pyramid shape. The first protrusion 10 includes a first inclined surface 11 and a second inclined surface 12 facing the outlet side, and a third inclined surface 13 and a fourth inclined surface 14 facing away from the outlet side, the first inclined surface 11 and the second inclined surface 12 are connected to the second reference surface S2, and the third inclined surface 13 and the fourth inclined surface 14 are connected to the second reference surface S2. The second protrusion 20 includes a fifth inclined surface 21 and a sixth inclined surface 22 facing the outlet side and a seventh inclined surface 23 and an eighth inclined surface 24 facing away from the outlet side, the fifth inclined surface 21 and the sixth inclined surface 22 are connected to a second reference surface S2, the seventh inclined surface 23 and the eighth inclined surface 24 are connected to the second reference surface S2, wherein the second reference surface S2 is perpendicular to the first reference surface S1, and the second reference surface S2 extends toward the outlet direction of the outlet.
Through the setting, the air speed and the air volume of the air outlet at each position after the air outlet of the air outlet passes through the horizontal swinging blade can be better ensured to be consistent, and the use experience of a user can be favorably improved.
Further, the yaw blade of the present embodiment is symmetrical with respect to the second reference plane S2. Therefore, the uniformity of the outlet air of the air outlet in the horizontal direction after passing through the transverse swinging blades can be improved.
Fig. 3 is an isometric view of a yaw blade provided in accordance with another embodiment of the present application from a perspective. Referring to fig. 3, in a possible implementation manner, the yaw blade of the present embodiment further includes a plane 30 located on a side away from the air outlet, and the plane 30 is perpendicular to the second reference plane S2. Set up the side that the leaf back of yawing kept away from the air outlet into plane 30, can prevent that the leaf of yawing from cutting the user, be favorable to guaranteeing user's safety in utilization.
Further, in the present embodiment, the flat surface 30 smoothly transitions with the third inclined surface 13, the fourth inclined surface 14, the seventh inclined surface 23, and the eighth inclined surface 24. For example, the plane 30 and the third, fourth, seventh and eighth inclined surfaces 13, 14, 23 and 24 may be connected in a circular arc transition manner, so as to prevent the existence of a sharp area in the blade, and better ensure the safety of the user.
Fig. 4 and 5 are wind flow diagrams of the yaw blade in the use state in fig. 3, wherein wind flows in the direction indicated by the arrow in the figures.
Specifically, fig. 4 shows the swinging direction of the yaw blade in the cooling state and the flow direction of the outlet air, the yaw blade of the present embodiment may swing upward relative to the first reference plane S1 in the cooling state, at this time, most of the cold air is guided by the first protrusion 10, and a small part of the cold air is guided by the second protrusion 20; on the one side of horizontal swing leaf back to the air outlet, the pressure of the cold wind after being drained by first bellying 10 is greater than the pressure of the cold wind after being drained by second bellying 20, and two strands of cold wind converge and form pressure difference to make final air-out top-down blow off, the air-out wind feels softer, more presses close to natural wind, is favorable to improving user's use and experiences.
It can be understood that, it can swing downwards for first reference surface S1 to yaw the leaf under the heating state, and hot-blast air-out can be realized blowing out from bottom to top after the blade that sways this moment, and the air-out wind-feel is softer, more is close to natural wind, is favorable to improving user' S use and experiences.
Fig. 5 shows the wind guiding state of the horizontal swinging blade in the horizontal plane, and because the horizontal swinging blade is symmetrically arranged relative to the second reference plane S2, and the horizontal swinging blade is thicker in the middle position of the air outlet, the air outlet of the air outlet can uniformly flow to both sides of the horizontal swinging blade in the horizontal direction, so that the strength and the wind speed of the finally derived wind at each place in the horizontal direction tend to be consistent, which is beneficial to improving the use experience of users.
In another possible embodiment, the distance from the first protruding portion 10 to the first reference surface S1 may be smaller than the distance from the second protruding portion 20 to the first reference surface S1. At this time, when the horizontal swing blade is horizontally arranged in the air outlet, the pressure intensity of part of air outlet of the air outlet after passing through the first bulge part 10 is not equal to the pressure intensity of the other part of air outlet after passing through the second bulge part 20; that is, the effect that the air outlet of the air outlet forms pressure difference after passing through the horizontal swinging blade can be realized without swinging the horizontal swinging blade, so that the effect that the air outlet wind feeling is softer and is close to natural wind can also be realized.
In conclusion, the air outlet of the air outlet in this embodiment can be shunted by the first protrusion 10 and the second protrusion 20 after passing through the horizontal swing blade, because the pressure of the part of the air outlet passing through the first protrusion 10 is not equal to the pressure of the other part of the air outlet passing through the second protrusion 20, and the two parts of the air outlet intersect at one side of the horizontal swing blade away from the air outlet to form a pressure difference, so that the air outlet is soft in air feeling, closer to natural wind, and beneficial to improving the user experience.
