Abstract
The utility model provides a draught fan blade of an air conditioning outdoor unit. The draught fan blade comprises a blade portion (10) and a connecting portion (20). The blade portion (10) comprises a blade core (12) and a blade body (11) wrapping the blade core (12). The blade core (12) is fixed to the connecting portion (20). A transverse wrinkled reinforcing rib (14) is formed on the blade body (11) and penetrates through a front edge (17) of the blade body (11) and a rear edge (18) of the blade body (11). Radial wrinkled reinforcing ribs (15) are formed on an outer end portion (19) of the blade body (11). The radial wrinkled reinforcing ribs (15) are communicated with the transverse wrinkled reinforcing rib (14). The blade body is made of glass steel, a plurality of reinforcing ribs are arranged on the blade body, and the rear edge of the blade body is provided with sawteeth. Accordingly, the anti-deformation capability and crack resistance capability of the blade are improved, and meanwhile noises produced by a draught fan are effectively lowered.
Description
Technical field:
The utility model relates to the technical field of air-conditioning draught fan, more specifically to a kind of impeller of blower of air conditioner outdoor machine.
Background technique:
Large-size air conditioning is generally divided into indoor set and outdoor unit at present, is usually provided with blower fan and carries out cooling in outdoor unit.Adopting that the fan blade of existing air-conditioning outer machine blower fan has is made of plastic, some employing aluminum materials, also the employing aluminum alloy casting having forms, adopt the fan blade of plastics in use easily to occur that crackle produces fracture gradually, though adopt aluminum material can just not give birth to crackle because of aluminium hardness less, easily deform, although and adopt aluminum alloy casting not have the shortcoming of plastics and aluminium, cost of material and fabricating cost are all higher.During the fan blade of existing air-conditioning draught fan rotation simultaneously, fan blade and air produce friction and can produce larger noise.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of impeller of blower of air conditioner outdoor machine is provided, and it just has stronger resistance to deformation and anti-crack ability, can effectively reduce noise simultaneously.
Technology solution of the present utility model is as follows:
A kind of impeller of blower of air conditioner outdoor machine, comprise blade part and joint, blade part comprises blade core and is coated on the blade in blade core outside, described blade core is fixed on joint, on blade, form the cross reinforcing of the leading edge of penetrating blade and the accordion of trailing edge, on the outer end of blade, form the radial reinforced rib of accordion, described radial reinforced rib is connected with cross reinforcing.
Described blade core adopts steel material, and blade adopts glass steel material, on the blade contacting, forms stiffening rib with blade core.
On the trailing edge of described blade, form some sawtooth.
The beneficial effects of the utility model are:
It adopts glass fibre reinforced plastics to make blade, is provided with some stiffening ribs, and is provided with sawtooth on blade on the trailing edge of blade simultaneously, at the resistance to deformation and the anti-crack ability that improve blade, has effectively reduced the noise that blower fan produces simultaneously.
Accompanying drawing explanation:
Fig. 1 is easy structure schematic diagram of the present utility model;
Fig. 2 is the sectional structure schematic diagram at blade core of the present utility model place.
In figure: 10, blade part; 11, blade; 12, blade core; 13, stiffening rib; 14, cross reinforcing; 15, radial reinforced rib; 16, sawtooth; 17, leading edge; 18, trailing edge; 19, outer end; 20, joint.
Embodiment:
Embodiment: see shown in Fig. 1,2, a kind of impeller of blower of air conditioner outdoor machine, comprise blade part 10 and joint 20, blade part 10 comprises blade core 12 and is coated on the blade 11 in blade core 12 outsides, described blade core 12 is fixed on joint 20, on blade 11, form the cross reinforcing 14 of the leading edge 17 of penetrating blade 11 and the accordion of trailing edge 18, form the radial reinforced rib 15 of accordion on the outer end 19 of blade 11, described radial reinforced rib 15 is connected with cross reinforcing 14.
Described blade core 12 adopts steel material, and blade 11 adopts glass steel material, on the blade 11 contacting, forms stiffening rib 13 with blade core 12.
On the trailing edge 18 of described blade 11, form some sawtooth 16.
Working principle: adopt glass fibre reinforced plastics to make blade 11, and be provided with cross reinforcing 14 and radial reinforced rib 15 at blade 11, thereby improved that it is anti-aging, the performance of cracking resistance, resistance to deformation, described cross reinforcing 14 and radial reinforced rib 15 communicates simultaneously, air-flow can be from trailing edge 18 from cross reinforcing 14 to blade 11 and the outer end of blade 11 go out, also on the trailing edge 18 of blade 11, sawtooth is set simultaneously, can effectively reduces the noise that blade 11 produces.
Claims (3)
