Abstract
The invention relates to an impeller structure of a centrifugal lampblack filter, which comprises a multi-wing type centrifugal impeller body (1) and is characterized by also comprising a meshy side filtering plate (2); and the side filtering plate (2) is externally fixed on the outer periphery of the multi-wing type centrifugal impeller body (1) so as to be capable of rotating at high speed together with the multi-wing type centrifugal impeller body (1). The impeller structure only increases the meshy side filtering plate (2) based on the original structure of the multi-wing type centrifugal impeller body (1); therefore, the structure and the preparing technique thereof are simple and reasonable and the cost is low, thus being convenient for popularization and application in large batch; moreover, the impeller body can not exert larger blowing force on the side filtering plate or a front filtering plate and the noise is low; the purifying effect of the impeller structure is higher by more than 100 percent of the traditional method through actual detection, which means that the purifying rate exceeds 60 percent; the purifying effect is good; moreover, the effect of the impeller structure to the air amount does not exceed 4 percent through actual detection and the effect of the of the impeller structure to the air pressure does not exceed 2 percent.
Description
Technical field
The present invention relates to a kind of centrifugal lampblack filter that is used for range hood, relate in particular to a kind of blade wheel structure of centrifugal lampblack filter.
Background technique
The household cooker hood lampblack filter is equipped with a filter screen at the intake grill place of centrifugal blower, utilize the centrifugal force of impeller on the blower fan to separate oil smoke, the air that has oil smoke is sucked by the negative pressure that the blower fan of high speed rotating produces, air touches condensation behind filter screen and the impeller, in the separated swab case that drips at last in the lampblack filter of oil smoke.This method detects through environmental administration, and under the situation of big oil smoke amount, purification ratio is 20%-30%.
In order to increase purifying effect, it is that the Chinese utility model patent " centrifugal filtration formula smoke purifier " of ZL01250306.1 (notification number is CN2497855Y) has disclosed a kind of like this centrifugal filtration formula smoke purifier that one patent No. is arranged, it comprises casing and hollow face shield, intermediate portion in the casing is equipped with motor by the motor bearing, on the output shaft of motor fan blade is installed, be provided with arc wind waveguide plate around motor and the fan blade, the top, rear portion of casing is provided with the rear portion exhaust outlet, the place ahead, bottom of casing is provided with swab case corresponding to the oil groove indentation, there of arc wind waveguide plate, it is characterized in that: centrifugal filtration net wheel also was installed before being positioned at fan blade on the output shaft of motor, and centrifugal filtration net wheel constitutes by netting the filter screen silk of taking turns skeleton and being radial arrangement on net wheel skeleton.
The device purifying effect of aforementioned centrifugal filtration formula smoke purifier obviously improves, but relating to parts, complete machine needs on output shaft, to be provided with specially centrifugal filtration net wheel more, and this centrifugal filtration net wheel constitutes by netting the wheel skeleton and taking turns the filter screen silk that is radial arrangement on the skeleton at net, so structure and manufacturing process complexity, the cost height can not be applied in batches; Also have after testing, the complete machine wind loss of aforementioned centrifugal filtration formula smoke purifier causes sucking the oil smoke ability and reduces more than 25%; Also have aforementioned structure in the course of the work fan blade centrifugal filtration net wheel is had the bigger power of blowing effect, so noise increases above 2dB; Aforementioned centrifugal filtration formula smoke purifier cleans inconvenient, not only will dismantle during cleaning and cleaning of centrifugal filter screen wheel, unpicks and washes fan blade in addition; Because centrifugal filtration net wheel will be installed before being positioned at fan blade on the output shaft of motor, so need be with the output shaft of motor, and centrifugal filtration net wheel is installed in the far-end of output shaft, therefore the output shaft of motor is stressed bigger, the output shaft of motor is shaken, easily produced noise and fragile motor.
In sum, the existing centrifugal lampblack filter that is used for range hood also can be further improved.
Summary of the invention
Technical problem to be solved by this invention is the blade wheel structure that the centrifugal lampblack filter of a kind of structure and manufacturing process advantages of simple is provided at above-mentioned prior art present situation, this blade wheel structure can make centrifugal lampblack filter, and noise is little in the course of the work, but also is convenient to clean.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of blade wheel structure of centrifugal lampblack filter, comprise the multiple wing type centrifugal impeller body, it is characterized in that: also comprise the side filter plate of mesh, this side filter plate outsourcing is fixed on the outer peripheral surface of multiple wing type centrifugal impeller body with can be with multiple wing type centrifugal impeller body high speed rotating.
The intake grill end that the preceding filter plate that also further comprises mesh, this preceding filter plate are fixed on the multiple wing type centrifugal impeller body is with can be with multiple wing type centrifugal impeller body high speed rotating.Filter plate can further increase the probability that the lampblack filter that uses this blade wheel structure contacts with oil smoke, enhancing filtering oil smoke effect before being provided with.
Described side filter plate and preceding filter plate are punching net, steel wire or other punching press web plate.
The thickness of described side filter plate and preceding filter plate is 0.2～1 millimeter.
Mesh diameter on described side filter plate and the preceding filter plate is of a size of 1～8 millimeter.
For solving aforementioned technical problem, also can adopt following scheme, a kind of blade wheel structure of centrifugal lampblack filter, comprise the multiple wing type centrifugal impeller body, it is characterized in that: also comprise the preceding filter plate of mesh, the intake grill end that this preceding filter plate is fixed on the multiple wing type centrifugal impeller body is with can be with multiple wing type centrifugal impeller body high speed rotating.
Compared with prior art, the invention has the advantages that: this blade wheel structure only increases the side filter plate of mesh on the basis of original multiple wing type centrifugal impeller body structure, or the preceding filter plate of increase mesh, so structure and manufacturing process advantages of simple, with low cost are convenient to apply in enormous quantities; Also have no matter be the side filter plate or before filter plate all be fixed together and can be with multiple wing type centrifugal impeller body high speed rotating with the multiple wing type centrifugal impeller body, impeller body can the offside filter plate or preceding filter plate the power of blowing is more greatly arranged, noise is little; Be higher than conventional method more than 100% through surveying this blade wheel structure purifying effect, promptly purification ratio surpasses 60%, and good purification also has through surveying this blade wheel structure the influence of air quantity is no more than 4%, and the influence of blast is no more than 2%; Because side filter plate or preceding filter plate and multiple wing type centrifugal impeller body are structure as a whole, and the multiple wing type centrifugal impeller body is fixed on the proximal points of motor output shaft, promptly be positioned at and the close position of motor, need not the output shaft of motor is extended especially, therefore motor output shaft is stressed little, can further reduce the machine operation noise, guarantee that machine operation is stable.
