Description
Technical field
The utility model relates to the blower fan structure of range hood, especially a kind of subsection blade and embedded air-ducting ring blower fan.
Background technique
Along with the pay attention to day by day with health perception that improves constantly of people's living standard, people are also increasing to the demand of range hood, simultaneously also more and more higher to the performance requirement of range hood.And the essential core parts of range hood inside are blower fan, the quality of blower fan determines the quality of the performance of range hood.The blower fan structure that the range hood sold in the market adopts mainly is divided into following two kinds of situations: one, air-ducting ring does not insert impeller inner ring, air-ducting ring air inlet diameter is substantially identical with impeller inner ring diameter, and impeller front disc and air inlet ring end face have certain assemblage gap; Two, air-ducting ring inserts impeller inner ring, and air-ducting ring inner ring and impeller inner ring have certain assemblage gap.In method one, air-ducting ring does not insert impeller inner ring, the intake grill diameter of air-ducting ring is substantially identical with impeller inner ring, relative to method two, there is larger incoming air area, but shortcoming is, there is gap between impeller front disc and air-ducting ring end face, make the leakage current of impeller and inside, air channel from the air intake air-flow of diametral interference air inlet.The air-ducting ring of method two inserts impeller inner ring, making the leakage current of impeller and inside, air channel from axially entering impeller, interference can not be produced to the air intake of air-ducting ring air inlet, but shortcoming being, air-ducting ring intake grill diameter is less than impeller inner ring diameter, decreases incoming air area.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides that a kind of air inlet effect is good, the few subsection blade of turbulent flow and embedded air-ducting ring blower fan near air-ducting ring.
The utility model solves the technological scheme that its technical problem adopts: this subsection blade and embedded air-ducting ring blower fan, mainly comprise ducting assembly, air-ducting ring, impeller and motor, motor is fixed by screws on ducting assembly, impeller set is on the axle of motor, impeller is made to be connected on the axle of motor by aluminum cap, air-ducting ring is fixed by screws on ducting assembly, and the intake grill of air-ducting ring embeds the inner ring of impeller.Described ducting assembly is formed by putting to be welding as one by plate, wind path wall and exhaust outlet behind air channel header board, air channel.Described motor is fixed on behind air channel on plate, and described air-ducting ring is fixed on the header board of air channel; Described impeller forms by riveting to be integrated by enclosing under impeller Shang Quan, leaf frame, blade and impeller.Described blade is set to hypotenuse at the shroud air intake place of impeller.
The effect that the utility model is useful is: the utility model structure is not when reducing former air channel incoming air area, improve the air output in air channel, effectively can reduce the air turbulence phenomenon near air-ducting ring simultaneously, and because adopting subsection blade structure, alleviate the weight of impeller, improve the smoking efficiency of cigarette machine.

Description of reference numerals: ducting assembly 1, air-ducting ring 2, impeller 3, aluminum cap 4, motor 5, air channel header board 6, plate 7 behind air channel, wind path wall 8, exhaust outlet 9, impeller encloses 10, leaf frame 11, blade 12, encloses 13 under impeller.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, this subsection blade and embedded air-ducting ring blower fan, mainly comprise ducting assembly 1, air-ducting ring 2, impeller 3 and motor 5, and ducting assembly 1 to be welding as one by point by plate 7, wind path wall 8 and exhaust outlet behind air channel header board 6, air channel 9 and to form.Motor 5 to be fixed by screws in behind air channel on plate 7.Impeller 3 is enclosed within the axle of motor 5, and make impeller 3 be connected on the axle of motor 5 by aluminum cap 4, air-ducting ring 2 is fixed by screws on air channel header board 6, and the intake grill of air-ducting ring 2 embeds the inner ring of impeller 3.Impeller 3 by impeller enclosing 10, leaf frame 11, circle 13 is integrated by riveted joint and forms under blade 12 and impeller.Blade 12 is treated to hypotenuse at the shroud air intake place of impeller 3 by top rake, becomes subsection blade, increases incoming air area.
The utility model adopts subsection blade and embedded air guide ring structure, increase the incoming air area of air-ducting ring 2, and air-ducting ring 2 inserts impeller 3 inner ring, impeller 3 is made to enter impeller 3 with the leakage current of inside, air channel from axial, effectively can stop from the air-flow leaked between impeller 3 and air channel along air-ducting ring 2 diametral interference air channel air intake, avoid the disorder of air intake air-flow, and because adopting subsection blade impeller, alleviate the weight of impeller, thus promote the performance in air channel.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
