Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The invention is described below with reference to the accompanying drawings in connection with specific embodiments.
Example one
Fig. 1 is the utility model provides an overall structure schematic diagram of air-out pendulum page or leaf, fig. 2 is the utility model provides an air-out pendulum page or leaf's blade structure schematic diagram that provides refers to fig. 1 to fig. 2 and shows, the embodiment of the utility model provides an air-out pendulum page or leaf, include: two air deflectors 100 arranged oppositely, and a blade 200 connected between the two air deflectors 100.
The two surfaces of the blade 200 are provided with a plurality of soft wind groups 210, each soft wind group 210 comprises a plurality of spherical pits 211 which have the same diameter and are uniformly distributed in the length direction of the blade 200, the diameters of the spherical pits 211 of two adjacent soft wind groups 210 are different, and the diameter of the spherical pit 211 of the soft wind group 210 far away from the air deflector 100 is larger than the diameter of the spherical pit 211 of the soft wind group 210 near the air deflector 100.
Specifically, the air outlet flap is installed at the air outlet of the air conditioner, the two air deflectors 100 arranged oppositely are used for air outlet, the two air deflectors 100 are of flat plate structures, and the length and width of the two air deflectors 100 depend on the size of the air outlet of the air conditioner. The air guide plate 100 may open the air outlet when the air conditioner is started and close the air outlet when the air conditioner is stopped, so as to prevent dust and foreign materials from entering the inside of the air conditioner.
The blades 200 connected between the two air deflectors 100 can guide the air outlet direction, so as to meet the air blowing requirements under different situations.
In the prior art, the blade is a continuous plane, so that the contact area between the air outlet and the blade is large, namely, the friction area is large, so that the blade vibrates to generate noise, and the air supply distance is short due to large wind resistance.
In order to solve the above problem, the blade 200 provided in this embodiment has a plurality of spherical recesses 211 on both surfaces, and when the air flows out, the contact area between the air flow and the blade 200 is greatly reduced compared to the contact area between the air flow and the blade when the blade is a continuous plane, that is, the friction area between the air flow and the blade 200 is reduced, so that the vibration frequency of the blade 200 is reduced, the noise is reduced, and meanwhile, the air flow can generate a vortex when passing through the spherical recesses 211, thereby reducing the wind resistance, and further prolonging the air supply distance.
Specifically, in order to fully utilize the wind softening effect of the spherical pits 211, in this embodiment, a plurality of spherical pits 211 with different diameters are disposed on two surfaces of the blade 200, the diameter of the spherical pit 211 far away from the air deflector 100 is greater than that of the spherical pit 211 near the air deflector 100, a plurality of spherical pits 211 with the same diameter and uniformly distributed in the length direction of the blade 200 form a wind softening group 210, and the diameters of the spherical pits 211 of two adjacent wind softening groups 210 are different. That is, the diameter of the spherical recess 211 decreases from the central axis of the width direction of the blade 200 (parallel to the length direction of the blade 200) to both sides, and the numerical value of the diameter may be symmetrical along the central axis.
It is easy to understand that the outlet airflow generates a vortex when passing through the spherical pits 211, the vortex generated when the outlet airflow passes through the spherical pits 211 with smaller diameter is smaller, and the vortex generated when the outlet airflow passes through the spherical pits 211 with larger diameter is larger. The large vortices have a larger holding power to the fluid molecules than the small vortices, and thus the outlet airflow is concentrated at the spherical pits far away from the air deflector 100, i.e. concentrated near the central axis of the blade 200 in the width direction. So, can make the air-out air current further reduce with the frictional area of blade 200, further reduce the noise, the loss of wind is littleer simultaneously, further increases the air supply distance, reduces energy consumption.
It should be noted that the number of the soft wind groups 210 needs to be specifically arranged according to the specific size of the blade, and the diameter of the spherical pit needs to be determined according to the specific size of the blade. The number of the soft wind groups and the size of the pits are not limited in this embodiment, and are not limited to the above examples.
Fig. 3 is a schematic cross-sectional view of a blade according to an embodiment of the present invention, and in an alternative embodiment, the cross-section of the blade 200 is streamline.
Specifically, in order to guide the outlet air more smoothly and reduce the noise generated by the vibration of the blade, the cross section of the blade 200 is streamline-shaped, and the streamline shape is in good fit with the flow of the flow field, so that the boundary layer is limited within a certain range, the energy consumption of viscous resistance is low, and the air supply distance can be further increased. The streamline shape is smooth and regular, no large fluctuation and edge angle exist, the fluid is mainly represented as the laminar flow on the surface of the streamline object, so that the blade 200 is ensured to bear smaller resistance relative to the air outlet, and the noise of the blade 200 caused by vibration can be further reduced.
Fig. 4 is a schematic cross-sectional view of a blade according to another embodiment of the present invention, and referring to fig. 4, in an alternative embodiment, the cross-section of the blade 200 may be designed to be a spindle shape.
It is easy to understand that the fusiform blade is equivalent to the shape of two streamline blades after being symmetrically jointed, and the fusiform has good flow jointing performance with a flow field, so that a boundary layer is limited within a certain range, the energy consumption of viscous resistance is low, and the air supply distance can be further increased. The spindle shape is smooth and regular, no large fluctuation and edge angle exist, and the fluid is mainly expressed as laminar flow on the surface of the spindle-shaped object, so that the blade 200 is ensured to bear smaller resistance relative to the air outlet, and the noise of the blade 200 caused by vibration can be further reduced.
Fig. 5 is a schematic cross-sectional structure view of an air outlet louver according to an embodiment of the present invention, and referring to fig. 5, optionally, the number of the blades 200 is multiple, and the multiple blades 200 are distributed at intervals and are radial; alternatively, the blades 200 are spaced apart and gathered.
Specifically, when the blades are in a radial shape, the outlet air is diffused air, and when the blades are in a gathered shape, the outlet air is gathered air. The user can adjust the wind direction according to the demand in order to adapt to the demand of blowing under the different situations.
Optionally, the blade 200 is connected between the two air deflectors by a first rotating shaft 310.
Specifically, the vane 200 may be rotationally swung by the first rotation shaft 310.
With the central axis of the air deflector 100 in the length direction (parallel to the width direction of the air deflector 100) as a boundary, when the number of the blades 200 is even, in the process of the air-out flap operation, half of the blades 200 swing leftwards at the same speed through the rotating shaft while the other half of the blades 200 swing rightwards at the same speed through the rotating shaft. For example, as shown in fig. 1, the outlet louver includes 6 blades, and during the operation of the outlet louver, the left three blades 200 swing leftward at the same speed X through the first rotating shaft, and the right three blades 200 swing rightward at the same speed X through the rotating shaft; the three left blades swing rightwards at the same speed X through a rotating shaft, and the three right blades swing leftwards at the same speed X through the rotating shaft.
When the number of the blades is odd, the most middle blade is perpendicular to the air outlet, and the rest half of the blades swing leftwards at the same speed through the rotating shaft while the other half of the blades swing rightwards at the same speed through the rotating shaft. For example, when the outlet louver includes 7 blades, in the operation process of the outlet louver, the middle blade is taken as the central axis, and the middle blade is kept to be fixed in a direction perpendicular to the length direction of the air deflector, while the left three blades swing leftwards at the same speed X through the rotating shaft, the right three blades swing rightwards at the same speed X through the rotating shaft; the three left blades swing rightwards at the same speed X through a rotating shaft, and the three right blades swing leftwards at the same speed X through the rotating shaft.
Thus, the blades are ensured to be in a radial shape or a gathering shape all the time. When the blades are in a radial shape, the outlet air is diffused air, and when the blades are in a gathering shape, the outlet air is gathered air. The user can adjust the wind direction according to the demand in order to adapt to the demand of blowing under the different situations.
The number of blades is determined according to the actual configuration of the air conditioner. The number of blades is not limited by the present embodiment, and is not limited to the above examples.
Optionally, the wind deflector 100 includes a first wind deflector 110 and a second wind deflector 120, and the width of the first wind deflector 110 is greater than the width of the second wind deflector 120. The first side of the vane 200 is connected to the first air guide plate 110, the second side of the vane 200 is connected to the second air guide plate 120, and the length of the first side of the vane 200 is greater than that of the second side of the vane 200.
Specifically, when the air conditioner stops operating, the blade rotates to be parallel to the length direction of the air guide plate through the first rotating shaft, and since the width of the air guide plate 110 is greater than that of the second air guide plate 120, the first air guide plate 110 can just close to the second air guide plate 120 through rotation. Prevent the interior from entering dust and foreign matters when the air conditioner is in a non-operation state.
Optionally, a second rotating shaft 320 is disposed at an end of the air outlet flap, and the second rotating shaft 320 is used for connecting the air outlet flap to the air outlet. Specifically, the second rotating shaft 320 connects the air outlet flap to the air outlet, and the air outlet flap can rotate up and down through the rotating shaft 320 so as to meet the air blowing requirements under different scenes.
Alternatively, the depth of the spherical pits 211 may be set to 0.3 mm.
Optionally, the diameter of the spherical pits 211 is between 2mm-5 mm.
Specifically, two adjacent soft wind groups 210 have spherical recesses 211 with different diameters. That is, the diameter of the spherical recess 211 decreases from the central axis of the length direction of the blade 200 toward both sides, and the numerical value of the diameter may be symmetrical along the central axis. For example, as shown in fig. 2, each blade 200 includes five soft wind groups 210 on one surface, and the diameters of the spherical pits in each row of the soft wind groups are 2.5mm, 3.0mm, 3.5mm, 3.0mm and 2.5mm from top to bottom. Thus, the outlet air can be more uniformly concentrated near the central axis of the blade 200 in the longitudinal direction and discharged. The friction area between the air outlet flow and the blades 200 can be further reduced, the noise is further reduced, the air loss is smaller, the air supply distance is further increased, and the energy consumption is reduced.
Alternatively, the blade 200 and the spherical recess 211 are integrally formed. After the depth of the spherical pits and the diameter of the spherical pits are determined, the mold is manufactured, and the blade 200 and the spherical pits 211 are integrally formed.
It should be noted that the present embodiment does not limit the depth of the spherical pits and the diameter of the spherical pits, and is not limited to the above examples.
The embodiment of the utility model provides an air-out pendulum page or leaf, through all set up a plurality of sphere pits on two surfaces at the blade, during the air-out, the area of contact of air current and blade reduces greatly with the area of contact of blade when the blade is a continuous plane with the area of contact of blade, and air-out and blade friction area reduce promptly, make blade vibration frequency reduce, and the noise reduction reduces the windage simultaneously and makes the air supply distance longer. The diameter of the spherical pit far away from the air deflector is larger than that of the spherical pit close to the air deflector, the spherical pits with the same diameters and uniformly distributed in the length direction of the blade form a soft air group, the diameters of the spherical pits of two adjacent soft air groups are different, and the outlet air flow is concentrated at the spherical pit far away from the air deflector and is discharged, namely concentrated near the central axis in the length direction of the blade.
