Abstract
The utility model relates to a bidirectional wind wheel. A centrifugal wind wheel comprises an inner core 1 and wind blades 2 evenly distributed on edges of the inner core; each wind blade is bent to a curved surface on a direction axially perpendicular to a wind wheel, and is bent towards the same direction; the inner side of each wind blade 2 is connected with one auxiliary wind blade 3, each auxiliary wind blade is also bent to a curved surface on the direction axially perpendicular to the wind wheel, and the bend direction of the auxiliary wind blade 3 is opposite to the bend direction of the wind blade 2; when the wind wheel rotates towards a positive direction, air is sucked in from an axial direction, and is exhausted from an air outlet 6; when the wind wheel rotates towards a negative direction, the auxiliary wind blades act, the air is sucked in from the air outlet 6, and is exhausted from the axial direction.
Description
The utility model relates to a kind of structure of centrifugal type wind wheel, a kind of Bidirection air vane.
Wind wheel is the parts of household electric appliance such as ventilation fan, super bath, ventilating fan.Centrifugal type wind wheel comprises inner core and fan blade, and fan blade is evenly distributed on the edge of inner core, and fan blade is bending to a curved surface with rotor shaft to vertical direction, and each fan blade is to the equidirectional bending.When the wind wheel high speed rotating, rely on the effect of fan blade, air from axial suction, is discharged from the exhaust outlet of side.This centrifugal type wind wheel is only just having the air draft effect when the bending direction of fan blade rotates, during backward rotation the air draft effect very weak, oppositely air draught inwards.
The purpose of this utility model is the structure that proposes the centrifugal type wind wheel of the two-way exhausting of a kind of energy, a kind of Bidirection air vane.
This Bidirection air vane, comprise inner core and fan blade, fan blade is evenly distributed on the edge of inner core, fan blade is bending to a curved surface with rotor shaft to vertical direction, each fan blade is to the equidirectional bending, the inboard of the every fan blade secondary fan blade of a slice of also ining succession, above-mentioned secondary fan blade also with rotor shaft to vertical direction bending, become curved surface, the direction of secondary fan blade bending is opposite with the bending direction of fan blade.
This Bidirection air vane plays the air draft effect when the bending direction to fan blade rotates, air from axial suction, is discharged from the exhaust outlet of side.During backward rotation, because the direction of the bending of secondary fan blade is opposite with the bending direction of fan blade, at this moment, secondary fan blade works, and air is sucked from the exhaust outlet of side, from axial discharge, plays the effect of reverse air draft.
Accompanying drawing 1 is the structural drawing of this Bidirection air vane;
Accompanying drawing 2 is the sectional view of Fig. 1;
Accompanying drawing 3 is the A-A sectional view of Fig. 1;
Accompanying drawing 4 is the B-B sectional view of Fig. 3;
Accompanying drawing 5 is the structural drawing of another kind of Bidirection air vane;
Accompanying drawing 6 is the structural drawing of another Bidirection air vane.
As Fig. 1, Fig. 2 and shown in Figure 3, this Bidirection air vane, comprise inner core 1 and fan blade 2, fan blade is evenly distributed on the edge of inner core, fan blade is bending to a curved surface with rotor shaft to vertical direction, each fan blade is to the equidirectional bending, the inboard of the every fan blade 2 secondary fan blade 3 of a slice of also ining succession, and secondary fan blade also is being bent to curved surface with rotor shaft to vertical direction.As shown in Figure 1 and Figure 4, the direction of secondary fan blade 3 bendings is opposite with the bending direction of fan blade 2.Dot and dash line is depicted as the shell of wind wheel among Fig. 1.5 is the axis hole of inner core, is used for inserting the axle of motor.When the wind wheel forward rotation, promptly when the arrow C direction was rotated, air was discharged from exhaust outlet 6 from axial suction.When the wind wheel backward rotation, secondary fan blade works, and air sucks from exhaust outlet 6, from axial discharge, is reverse air draft.
As shown in figures 1 and 3, an annulus 4 that fan blade 2 and secondary fan blade 3 are fixed can also be arranged on the top margin 7 of described fan blade 2.The effect of this annulus is that fan blade is played reinforing function, increases the rigidity of whole wind wheel.
The quantity of the secondary fan blade 3 of this Bidirection air vane can be unequal with the quantity of fan blade 2.For example, as shown in Figure 6, the quantity of secondary fan blade 3 is half of fan blade 2 quantity, every a slice fan blade 2 the secondary fan blade 3 of a slice is arranged.Such structure can avoid secondary fan blade too crowded because of being in inner ring.
As shown in Figure 5, the secondary fan blade 3 of this Bidirection air vane can also become to be staggered with fan blade 2, and does not directly link to each other, and leaves slit 8 between secondary fan blade 3 and the fan blade 2.
