Detailed description of the invention
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Fig. 1 to 5, according to motor noise-reducing device of the present utility model, comprise and be located at motorOutside noise reduction shroud 10, is provided with noise reduction hole 20 on noise reduction shroud 10. The utility model is by arranging coverBe located at the noise reduction shroud of outside motor, and noise reduction hole is set on noise reduction shroud, what when machine operation, produce makes an uproarSound, by the outside communication process in noise reduction hole 20, due to effects such as friction, reflections, can make sound waveEnergy weakens, thereby reduces noise.
Preferably, shown in Fig. 5, noise reduction hole 20 is the flared hole of shrinking gradually from inside to outside,Be that internal orifice is large, outer young, make sound wave by noise reduction hole 20, strengthen the friction effect of noise, moreEffectively reduce noise energy. In the time that the thickness of noise reduction shroud 10 exceedes 10mm, sound wave passes through noise reductionBehind hole 20, energy has almost been consumed, and can effectively reach noise reduction.
Particularly, in conjunction with shown in Fig. 1 to 4, noise reduction shroud 10 comprise columnar periphery wall 11 and withThe end wall 12 that the output shaft end of motor coordinates, is provided with the axle coordinating with motor output shaft on end wall 12Hole 13. When installation, noise reduction shroud 10, motor shaft is by the outside of axis hole 13. Preferably, noise reduction hole20 are evenly distributed on periphery wall 11 and end wall 12, are conducive to improve noise reduction.
Shown in Fig. 1 and Fig. 2, install for convenient, on the periphery wall 11 of noise reduction shroud 10, arrangeThere is mounting part 14, on mounting part 14, there is installing hole, can adopt screw to be located in peaceIn dress hole, noise reduction shroud 10 is fixed in outside or other structures of motor. More specifically, installFixed part 14 is positioned at one end relative with end wall 12 on periphery wall 11, convenient by fixing noise reduction shroud 10Install upper at motor, can avoid corresponding installing hole is set on motor on the one hand, make to installMore convenient; On the other hand, also can avoid noise reduction shroud 10 and motor directly fixing, prevent that motor from shakingThe moving noise reduction shroud 10 being delivered to, produces other noises.
The utility model also provides a kind of air-conditioner, comprises motor and aforesaid motor noise-reducing device,Motor noise-reducing device is located at the outside of motor, produces noise thereby slacken motor, improves the quality of products.Preferably, shown in Fig. 6, air-conditioner also comprises electric machine support 30, and motor noise-reducing device is fixed onOn electric machine support 30, can avoid corresponding installing hole is set on motor on the one hand, make to installMore convenient; On the other hand, also can avoid noise reduction shroud 10 and motor directly fixing, prevent that motor from shakingThe moving noise reduction shroud 10 being delivered to, produces other noises.
As can be seen from the above description, the utility model the above embodiments have realized following skillArt effect:
According to motor noise-reducing device of the present utility model and air-conditioner, be located at outside motor by settingNoise reduction shroud, and noise reduction hole is set on noise reduction shroud, the noise producing when machine operation is by noise reduction holeOutwards, in communication process, due to effects such as friction, reflections, can make acoustic wave energy weaken, thereby fallLow noise.
The foregoing is only preferred embodiment of the present utility model, be not limited to this practicality newType, for a person skilled in the art, the utility model can have various modifications and variations.
