Abstract
The utility model discloses a low noise motor, through the structure that changes the fan casing, it is also more smooth sooner that the heat of messenger's fan is arranged. The fan casing of output shaft, fan and U type bowl form on host computer, host computer, the feature structure does: be equipped with a plurality of bellied drainage plates at the bottom of the cover of fan casing in the fan casing, the one end and the lateral wall of drainage plate are connected, and the other end extends to the center directions at the cover end, open between each drainage plate at the cover end has the ventilation hole. The utility model discloses a fan casing has increased the drainage plate, plays the effect of carrying out the drainage to the wind of fan, and the wind energy of fan is discharged enough smoothly like this, and can reduce wind retained the production in the fan casing noise, and very big degree has reduced the noise of fan.
Description
Technical field
The utility model relates to a kind of motor, is specifically related to a kind of low noise motor.
Background technology
The noise that family life electrically produces can affect the quality of life of people, the particularly present electric era, mostly all motor is needed in home electric, wherein motor is also noise source, the fan of motor produces noise, the vibrations of the casing of motor produce noise, rotor bearing produces noise etc., here especially the noise of fan generation is larger, and impact is also larger, trace it to its cause and be that the obstruction of noise and fan guard that the flabellum of fan shakes generation makes wind not easily discharge the noise produced in fan guard, so with regard to above problem, we are through improving the motor of a kind of low noise of invention.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect, and provides a kind of motor reducing noise, and by changing the structure of fan guard, what the heat of fan was arranged is faster also more smooth.
For solving the problems of the technologies described above, the technical solution of the utility model is: low noise motor, comprises the output shaft on main frame, main frame, fan and fan guard, and described fan guard surrounds U-shaped bowl-shape by sidewall and the cover end, and the openend of fan guard is enclosed within main frame; In fan guard, be provided with the drainage plate of multiple projection at the bottom of described cover, one end of drainage plate is connected with sidewall, and the other end extends to the center position at the bottom of cover; Between each drainage plate, ventilation hole is had at the bottom of described cover.
Described drainage plate at least two, and along covering the center annular array at the end.
Described drainage plate is aerofoil profile, and bending direction is consistent with the direction of rotation of the flabellum of fan.
Described Zhao Di center is provided with projection, and projection has centre bore, through there being output shaft in centre bore.
The beneficial effects of the utility model
Compared with conventional art, fan guard of the present utility model adds drainage plate, and play the effect wind of fan being carried out to drainage, the wind energy of such fan is discharged enough smoothly, and the noise that wind retains generation in fan guard can be reduced, largely decrease the noise of fan.
The center at the cover end is also had to be provided with projection, through there being output shaft in the centre bore of projection, such output shaft rotates in the centre bore of fan guard, and fan guard, fan, output shaft, main frame connect as one, such vibrations that can reduce fan guard, and then reduce the noise produced because of vibrations.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the end view of fan guard of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is further elaborated.
As Fig. 1 with shown in Fig. 2, low noise motor, comprises the output shaft 2 on main frame 1, main frame 1, fan 3 and fan guard 4, and fan guard 4 surrounds U-shaped bowl-shape by sidewall 5 and the cover end 6, and the openend of fan guard 4 is enclosed within main frame 1; The cover end 6, is provided with eight protruding drainage plates 7 in fan guard 4, and along covering the center annular array at the end 6, drainage plate 7 is in aerofoil profile, and bending direction is consistent with the direction of rotation of the flabellum of fan 3; The cover end 6, has ventilation hole 8 between each drainage plate 7.
Fan guard 4 of the present utility model adds drainage plate 7, plays the effect wind of fan 3 being carried out to drainage, and the wind energy of such fan 3 is discharged enough smoothly, and can reduce the noise that wind retains generation in fan guard 4, largely decreases the noise of fan.
The present embodiment 6 centers at the bottom of cover are provided with projection, projection have centre bore 9, through there being output shaft 2 in centre bore 9.Such output shaft 2 is 9 rotations in the centre bore of fan guard, and fan guard 4, fan 3, output shaft 2, main frame 1 connect as one, and can reduce the vibrations of fan guard 4 like this, and then reduce the noise produced because of vibrations.
