Abstract
The invention discloses a motor wind shield structure which comprises a wind shield, a plurality of air inlet grooves formed on the right side of the wind shield, an air inlet arranged at the end part of the air inlet grooves, and a plurality of guide sheets formed on the other side of the wind shield. The tail end of the guide sheets forms a tail end part. The tail end part extends towards the central part of the wind shield until the tail end part is close to the edge of the shaft hole. In the motor wind shield structure, the extended tail end part of the guide sheets is close to the edge of the shaft hole, so as to realize the consistent direction and smoothness of the air flow passing through the wind shield, increase the fan capacity of the motor air and ensure the rapid heat dissipation. Additionally, the motor wind shield structure allows the motor to function more steadily with less vibration and improves the reliability of the whole machine.

In general, motor is to be transformation of electrical energy the machine of kinetic energy, and such motor can be divided into transformation of electrical energy to be the electric rotary machine that rotatablely moves and to be transformation of electrical energy the reciprocable machine of straight reciprocating motion.
Motor is installed on the nearly all product that uses in the families such as refrigerator, air-conditioning, washing machine, electric fan and dust catcher as power source.
Shown in Fig. 1～3, existing monophase machine includes the shell 1 of opening, inboard fixed stator 2 at shell 1, be provided with the inner peripheral surface of stator 2 rotor 3 of keeping certain distance, can being rotated in the inboard of stator 2, central part at rotor 3 is equipped with rotating shaft 4, the both side ends of rotating shaft 4 is provided with bearing (not shown), and bearing is fixing by shell 1 and fan housing 8, and rotating shaft 4 is rotated.On a side end of rotating shaft 4, be fixed with impeller 9, when rotating shaft 4 rotations, impeller 9 rotations.The impeller outside is fixing with motor housing 1 by impeller cover 10.Rotating shaft 4 is connected with impeller 9 with fan housing 8 by end cap 7
Being provided with the AC current conversion that will supply with at the upside of rotor 3 is the commutator-rectifier 5 of DC electric current; The both sides of commutator-rectifier 5 are provided with the outside of commutator-rectifier 5 and flexiblely contact, give commutator-rectifier 5 that power supply and and a pair of carbon brush 6 that forms with rotating shaft 4 vertical direction are provided.
(towards the one side of motor) is formed with a plurality of air intake ducts 12 to the fan housing 8 of prior motor in its front, is formed with air inlet 13 in the end of air intake duct 12, and the effect of air intake duct 12 is that steering current flows to air inlet 13.Another side at fan housing 8 is formed with a plurality of prerotation vanes 11, and the end formation terminal part 14 at prerotation vane 11 is formed with axis hole 15 in the centre of fan housing 8, and axis hole 15 cooperates with rotating shaft 4.
The terminal part of the prerotation vane in the fan housing of prior motor and the central part of fan housing distance are far away, during the airflow passes gathering sill in the terminal mixed flow of prerotation vane, make airflow obstruction, cause under the effect of the air-flow of different directions that electric motor fan suction weakens, motor oscillating increases.
Summary of the invention
The present invention proposes for overcoming the shortcoming that exists in the prior art, and purpose provides a kind of airflow smooth, electric motor fan air quantity of making and increases, is easy to dispel the heat and vibrate the fan housing structure of motor that reduces.
The technical solution used in the present invention is: a kind of fan housing structure of motor, the front (towards the one side of motor) that is included in fan housing is formed with a plurality of air intake ducts, end at air intake duct is formed with air inlet, another side at fan housing is formed with a plurality of prerotation vanes, end at prerotation vane forms terminal part, and terminal part prolongs until the edge near axis hole to the central part of fan housing.
Centre at fan housing is formed with axis hole, and axis hole cooperates with rotating shaft.
Axis hole, prerotation vane, air intake duct, air inlet and terminal part integrated injection molding.
Advantage and good effect that the present invention has are: fan housing structure of motor of the present invention is owing to extend to the end of prerotation vane at the edge of close axis hole, thereby make airflow direction unanimity, the airflow smooth of air-flow by fan housing the time, the electric motor fan air quantity increases, rapid heat dissipation.The reliability that motor rotation is steady more simultaneously, vibration has reduced, improved complete machine.

Embodiment
Followingly fan housing structure of motor of the present invention is elaborated with reference to drawings and Examples:
The parts that the present invention is identical with the prior motor fan housing structure adopt identical symbol.
Shown in Fig. 1～4, monophase machine includes the inboard of shell 1 of the inner space of opening and is fixing stator 2, be provided with the inner peripheral surface of stator 2 rotor 3 of keeping certain distance, can being rotated in the inboard of stator 2, the central part of rotor 3 is inserted with rotating shaft 4, the both side ends of rotating shaft 4 is provided with bearing (not shown), bearing is fixing by shell 1 and fan housing 20, and rotating shaft 4 is rotated.Be fixed with impeller 9 on one side end of rotating shaft 4, when rotating shaft 4 rotations, impeller 9 rotations.The impeller outside is fixing with motor housing 1 by impeller cover 10.Rotating shaft 4 is connected with impeller 9 with fan housing 20 by end cap 7.
Being provided with the AC current conversion that will supply with at the upside of rotor 3 is the commutator-rectifier 5 of DC electric current, and the both sides of commutator-rectifier 5 are provided with and the flexible a pair of carbon brush 6 that contacts, power supply is provided and forms with rotating shaft 4 vertical direction for commutator-rectifier 5 in the outside of commutator-rectifier 5.
