Description
Technical field
The present invention relates to centrifugal blower technical field, particularly a kind of through-flow fan blade and air conditioner.
Background technology
At present, the design method of low pressure ventilation Volute Profile of Multi-blade Centrifugal Fan and immature, in ventilation heat exchange system
In, particularly for household products, such as：Cabinet-type air conditioner, air cleaner, dehumidifier etc., because this kind of product compactedness requires very high, lead to
The design of wind system is usually given way in the structure limitation of total system, sacrifices fan performance to reach system compact purpose.It is this
Product separate unit blower fan power consumption is small, but total amount is very big, consumes substantial amounts of electric energy, and " sacrifice part fan performance in industry
Reach compact " thought it is deep-rooted, do not allow malleable for the moment, therefore, how under the useful space design air output compared with
The maximum blower fan of high and efficiency, turn into the key problem in technology of this kind of Fan Energy-saving.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of through-flow fan blade and air conditioner.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of through-flow fan blade, including first member plate, median septum, right end plate and blade, left end is provided with the first member plate center
Through hole, step department is provided with the median septum and is used to be connected with machine shaft, the right end plate is closed harden structure.
As a preference, the step department includes link and connecting cylinder, and the connecting cylinder side is provided with fixation
Screw.
As a preference, the left end through hole is diameter 10mm~30mm circular hole.
As a preference, trapezoidal vertical securing plate is distributed with the link.
As a preference, the blade corresponds to fixing screws opening position and is provided with installing port.
A kind of air conditioner, it is built-in with the through-flow fan blade described in claim 1.
As a preference, also built-in L-type heat exchanger, the L-type heat exchanger surrounds through-flow fan blade.The present invention's is beneficial
Effect is：The through-flow fan blade coordinates the design of left end through hole by step department, right end plate is saved original steel shaft structure, also no longer
Bearing seat supports are needed, not only save cost, and avoid original axle pine phenomenon, fan blade production qualification rate is carried
It is high.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the stereogram of through-flow fan blade of the present invention；
Fig. 2 is the sectional view of the present invention；
Fig. 3 is the stereogram of air conditioner of the present invention；
Fig. 4 is the structure decomposition figure of the present invention.
Embodiment
In order that the object, technical solution and advantage of the application are more clearly understood, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.For the thorough explanation present invention, some certain details can be related in following description
Section.And in these no specific details, the invention can still be realized, i.e., the technical staff in art uses herein
These describe and stated that the others skilled in the art into art can more effectively introduce their work essence.
Reference picture 1, Fig. 2, a kind of through-flow fan blade, including first member plate 1, median septum 2, right end plate 3 and blade 4, the left end
Left end through hole 11 is provided with the center of plate 1, step department 5 is provided with the median septum 2 and is used to be connected with machine shaft, the right end plate
3 be closed harden structure, and so, machine shaft can is stretched into from left end through hole 11 and is connected with step department 5, realizes the peace of through-flow fan blade
Dress.It is this to design the steel shaft for avoiding the need for right-hand member, it is not required that bearing seat supports, to save through-flow fan blade and air-conditioning to a certain degree
The cost of device；And without steel shaft axle pine phenomenon is just not present, fan blade production qualification rate improves in fan blade.
The step department 5 includes link 6 and connecting cylinder 7, and the side of connecting cylinder 7 is provided with fixing screws 71, is easy to
After machine shaft insertion connecting cylinder 7, fixed with step department 5.
The left end through hole 11 is diameter 10mm~30mm circular hole, is easy to machine shaft to wear and connects, while is reduced to fan blade
The influence of rotation.In addition left end through hole 11 can also be designed to oval or square.
Trapezoidal vertical securing plate 61 is distributed with the link 6, further improves the stable degree of step department 5.The leaf
The corresponding opening position of fixing screws 71 of piece 4 is provided with installing port 41, is easy to screwdriver or other installation tools to be worn from installing port 41
Cross and stretch into through-flow fan blade installation machine shaft.The downside of installing port 41 of the present embodiment is square base, and upside is arched top, both firm
Solidness at installing port 41, also allow for installation tool operation.
Reference picture 3, Fig. 4, a kind of air conditioner, it is built-in with the through-flow fan blade described in claim 1, it is no longer necessary to which bearing block comes
Through-flow fan blade is installed.The also built-in L-type heat exchanger 8 of air conditioner, the L-type heat exchanger 8 surround through-flow fan blade, improve heat exchange efficiency.
Air conditioner includes square or circular casing 91, is wrapped in L-type heat exchanger 8, inlet and outlet is had before and after casing 91；Electricity
Machine, installed in through-flow fan blade and the side of first member plate 1, motor shaft 9 passes through the center hole of first member plate 1, is connected with fan blade step department；Bottom
Disk, motor are fixed on chassis, and motor shaft is perpendicular to chassis
According to above-mentioned principle, the present invention can also carry out appropriate change and modification to above-mentioned embodiment.Therefore, this hair
It is bright to be not limited to embodiment disclosed and described above, some modifications and changes of the present invention should also be as falling into this
In the scope of the claims of invention.
