Abstract
The utility model discloses a kind of cooking-fume exhauster blower shock-damping structure, comprise Blower Housing, motor, impeller and impeller central disc, described motor is fixed on Blower Housing, described impeller and impeller central disc fix, it is characterized in that: also include bracing ring and damping ring, be lining in damping ring inwall in described bracing ring and be fixed on motor output shaft, described damping ring by clamping between described bracing ring and mid-game inner ring.Compared with prior art, the utility model has the advantage of: this cooking-fume exhauster blower shock-damping structure is by arranging damping ring and the interior bracing ring being lining in damping ring inwall, and damping ring by clamping between bracing ring and impeller central disc, make to realize damping effect by damping ring between impeller and motor, thus greatly reduce because air-flow is unstable, impeller moves the steadily not good pneumatic and mechanical noise brought, and the thickness of choose reasonable damping ring, can adjust damping effect.
Description
Technical field
The utility model relates to a kind of range hood, especially relates to a kind of fan shock-absorbing structure of range hood.
Background technique
At present, range hood has become one of requisite kitchen fitting of ordinary family, during range hood work, all carry out lampblack suction exhausting by fan operation, the vibration of blower fan system and noise are mainly derived from the aerodynamic noise that impeller produces when rotating, and the mechanical vibration noise that air-flow is unstable, dynamic balance of impeller is not good etc. brings.In order to the noise produced when reducing blower fan system work, in existing cooking-fume exhauster blower system, because impeller and impeller central disc are for being rigidly connected, impeller central disc and motor shaft are for being rigidly connected, and whole blower fan system often all realizes damping effect by the beam between motor and shell.
If the patent No. is " a kind of structure of low-noise cooker hood " disclosed in the Chinese utility model patent of ZL 01239216.2 (Authorization Notice No. is CN 2485562 Y), connected as one by some screws between the motor housing of this blower fan and Blower Housing, and screw is lined with the beam of elastic material, beam is good to be in confined state after mounting, mounting screw is owing to being lined with beam, therefore the connection between motor and Blower Housing just connects for elasticity, thus effectively reduces noise.The defect of this shock-damping structure is, beam is compressed in an installation, and actual damping effect is poor, and owing to not arranging shock-damping structure between impeller and motor, the pneumatic and mechanical noise thus causing impeller to produce is larger.In sum, need to be further improved the shock-damping structure of existing cooking-fume exhauster blower system.
Model utility content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, provides a kind of and can reduce unstable by air-flow, that impeller moves the steadily not good pneumatic and mechanical noise brought cooking-fume exhauster blower shock-damping structure.
The utility model solves the problems of the technologies described above adopted technological scheme: this cooking-fume exhauster blower shock-damping structure, comprise Blower Housing, motor, impeller and impeller central disc, described motor is fixed on Blower Housing, described impeller and impeller central disc fix, it is characterized in that: also include bracing ring and damping ring, be lining in damping ring inwall in described bracing ring and be fixed on motor output shaft, described damping ring by clamping between described bracing ring and mid-game inner ring.
Preferably, described impeller central disc and bracing ring are rigid pipe, and described damping ring is soft shock absorber part.Impeller central disc and bracing ring are die cast as one by the damping ring included, and the thickness of choose reasonable damping ring, can adjust damping effect, and bracing ring adopts rigid pipe, can improve the reliability be connected with motor output shaft.
Further preferably, described damping ring is rubber parts.Certainly, damping ring also can adopt the elastic component be made up of other elastic materials.
Impeller central disc and bracing ring are along with motor output shaft synchronous axial system, preferably, the first restraining groove is had towards the bottom of motor side at described impeller central disc, the second restraining groove is had towards the bottom of motor side at described bracing ring, described motor output shaft is provided with the position-limited lever perpendicular to motor output shaft, and described position-limited lever is embedded in the first described restraining groove and the second restraining groove.
Preferred as above-mentioned either a program, be provided with top cover, and described top cover covers in described mid-game inner ring and damping ring on the top of described motor output shaft.
For being rigidly connected between motor and Blower Housing, preferably, described motor is fixed on Blower Housing by set screw.In addition, for improving the damping effect of blower fan, between motor and Blower Housing, also beam can be installed and fix with set screw.
Compared with prior art, the utility model has the advantage of: this cooking-fume exhauster blower shock-damping structure is by arranging damping ring and the interior bracing ring being lining in damping ring inwall, and damping ring by clamping between bracing ring and impeller central disc, make to realize damping effect by damping ring between impeller and motor, thus greatly reduce because air-flow is unstable, impeller moves the steadily not good pneumatic and mechanical noise brought, and the thickness of choose reasonable damping ring, can adjust damping effect.

Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figures 1 to 4, cooking-fume exhauster blower shock-damping structure in the present embodiment comprises Blower Housing 1, motor 2, impeller 3, impeller central disc 4, bracing ring 5 and damping ring 6, wherein, motor 2 is fixed on Blower Housing 1, impeller 3 and impeller central disc 4 fix, be lining in the inwall of damping ring 6 in bracing ring 5 and be fixed on motor output shaft 21, damping ring 6 by clamping between bracing ring 5 and mid-game inner ring 4.In the present embodiment, impeller central disc 4 and bracing ring 5 are rigid pipe, and damping ring 6 is soft shock absorber part, and such as damping ring 6 can adopt rubber, and impeller central disc 4 and bracing ring 5 are die cast as one by damping ring 6.After bracing ring 5 adopts rigid pipe, the reliability be connected with motor output shaft 21 can be improved.Different to the requirement of damping effect according to different blower fan, the thickness of choose reasonable damping ring can adjust damping effect.
Bracing ring 5, damping ring 6 and impeller central disc 4 synchronous axial system can be driven after rotating to make motor output shaft 21, the mounting structure that the present embodiment adopts is: have the first restraining groove 41 at impeller central disc 4 towards the bottom of motor 2 side, the second restraining groove 51 is had towards the bottom of motor 2 side at bracing ring 5, motor output shaft 21 is provided with and the position-limited lever 22 perpendicular to motor output shaft 21, and position-limited lever 22 is embedded in the first restraining groove 41 and the second restraining groove 51.In addition, on the top of motor output shaft 21, top cover 7 is installed, and top cover 7 covers in bracing ring 5 and damping ring 6.
