Abstract
The utility model relates to an AC centrifugal fan, in particular to an AC centrifugal fan suitable for being used on a small household electrical appliance. The AC centrifugal fan comprises a spiral casing consisting of a stand and a cover board, wherein one side of the spiral casing is provided with an air channel; the stand is internally provided with a rotor connected with a wind wheel; the rotor is internally provided with a dead axle on which a gasket, a wave washer, an elastic collar used for a hole, a preloaded spring, a wafer, a circlip for a shaft and a ball bearing are arranged; an outer pack of the rotor of the dead axle is provided with a stator solenoid; the lower side of the dead axle is also provided with an insulating base; and the wind wheel and the rotor are formed into a whole. The AC centrifugal fan has compact, attractive and skillful appearance, enables the rotor and the wind wheel to have better synchronous running effect when the rotor and the wind wheel are in running, improves the work efficiency and enables the wind wheel to be more quiet and stable in the rotating process.
Description
Technical field
The utility model is a kind of interchange centrifugal blower, particularly a kind of interchange centrifugal blower that is adapted on the small household appliances.
Background technique
In the prior art, exchanging rotor in the centrifugal blower and wind wheel is to be installed on the complete machine after successively being installed on the complete machine or rotor and wind wheel being assembled again.But ubiquity rotor and wind wheel synchronous operation poor effect; Concentricity is stable inadequately, occurs easily teetertottering thereby cause wind wheel to be in operation, thereby has influence on the balance movement and the working efficiency of complete machine, and what also become in operation is more complicated.
Chinese patent CN2512927, a kind of interchange centrifugal fan is disclosed, comprise housing, motor, wind wheel, intake grill and exhaust outlet, wind wheel is installed on the output shaft of motor, centrifugal blade is arranged on the wind wheel, the housing of this blower fan half-and-half separately docks mutually, and wind wheel wherein can form with plastic injection-moulded.After this interchange centrifugal fan is assembled into integral body, be fixed on the exhaust outlet of range hood or other venting gas appliance, blower fan is separated with the fuselage of venting gas appliance, body volume is dwindled greatly, saved the space.Can not well improve the efficient of work, the thickness of complete machine does not change.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of integrated design that exchanges centrifugal blower rotor and wind wheel is provided, and has reduced the thickness of complete machine, and whole weight also reduces to some extent, makes product appearance attractive in appearance small and exquisite.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of interchange centrifugal blower, comprise spiral case by a volute, spiral case by support and cover plate constitute, a side of spiral case is provided with the air channel, be provided with in support that rotor is connected with wind wheel, be provided with dead axle in the rotor, on dead axle, be provided with pad, wave washer, circlip for hole, preloading spring, packing ring, circlip for shaft, ball bearing, outsourcing at the dead axle rotor is provided with stator line bag, the downside of dead axle also is provided with insulator foot, and described wind wheel and rotor have a style of one's own.Wind wheel and rotor have a style of one's own, the structure that can be product is more compact attractive in appearance, incorporate design makes rotor and wind wheel that better synchronous operation effect be arranged, also improved simultaneously the concentricity between rotor and the wind wheel greatly, make wind wheel quieter steady in rotation process, make product that higher working efficiency and longer working life be arranged.
As preferably, the thickness of described interchange centrifugal blower is 39mm.After rotor and the wind wheel integrated design, whole thickness has greatly improved, and the improvement of thickness must make the minimizing of complete machine weight, makes complete machine dexterous more compact.
As preferably, described wind wheel is a lid shape, is provided with flange around the lid shape.
Therefore, interchange centrifugal blower of the present utility model, compact appearance, dexterity attractive in appearance makes rotor and wind wheel when operation, and better synchronous operation effect is arranged, and has improved the efficient of work, makes wind wheel quieter steady in rotating process.
