Abstract
The invention relates to a washing-free oil-repellent range hood impeller. The impeller comprises an impeller tray (1) and blades (2) on the impeller tray, and is characterized in that a plurality of corrugated grooves (3) are uniformly distributed on the surfaces of the base bodies of the impeller tray (1) and the blades (2) by etching; and a layer of fluoride coating in which Teflon is served as the matrix resin is filled on the surface of each groove by spraying. The washing-free oil-repellent range hood impeller provided by the invention is applicable to a range hood, and cannot be adhered with oil dirt during running, so that the purposes of being free of washing and avoiding oil adhering can be achieved.
Description
Technical field
The present invention relates to the parts of range hood, especially a kind ofly exempt to unpick and wash the non-stick oil ventilator impeller.
Background technique
The widely used centrifugal range hood in the whole world is actually the centrifugal fan of in the volute body of range hood, having adorned a band impeller at present.Its working principle be utilize negative pressure that impeller rotation produces that oil smoke is sucked in the blower fan and it is discharged to outdoor, oil smoke during through impeller with the blade collision of high speed rotating, the collision plane of blade can attach grease and dust, grease is amassed in generation; The partial product grease is splashed under the impeller action of centrifugal force again and flows down catchment cup in the spiral case; The partial product grease then can be stayed on the impeller under the effect of air-flow slowly by air-dry, makes impeller oil incrustation layer long-pending more thick more, and the effect of lampblack absorbing also descends thereupon; Cause impeller uneven simultaneously; Produce vibrating noise, and motor bearings is produced wearing and tearing, make range hood shortening in working life.Therefore need clean range hood frequently, wherein the cleaning of impeller accounts for more than 80 percent of whole cleaning amounts, cleaning be really one not only dirty but also tired, a time-consuming and headachy difficult problem.
So in the industry this was carried out extensive studies, as: on May 12nd, 2010 Hangzhou Boss Electric Co., Ltd, in Chinese model utility notice of authorization number 201463055 U, a kind of oil environmentally-friendly and energy-saving range hood of exempting from not unpick and wash is stickingly just disclosed.This scheme has just proposed on impeller, not to be sprayed with stickingly oil or nano paint.Though the concrete technology contents of not open not sticking oil of this scheme or nano paint finds that through relevant retrieval this coating comprises barium carbouate, nano titanium oxide, thinner and polyester varnish etc.; And in fact, polyester varnish is oil resistant not, and polyester varnish can dissolve under the effect of the unrighted acid in grease, and through using for a long time, not sticking oil or nano coating obscission can occur on impeller, thereby influence using effect.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above-mentioned shortcoming that existing technology exists, and a kind of non-stick oil ventilator impeller of exempting to unpick and wash is provided, and this impeller can not attach grease at work, realizes exempting from not unpick and wash stickingly oil.
The present invention solves the technological scheme that its technical problem adopts: a kind ofly exempt to unpick and wash the non-stick oil ventilator impeller, comprise the blade on wheel disc and the wheel disc; On the matrix surface of wheel disc and blade, etching evenly distributedly has many wave grooves; Filling spray on the groove face is the fluorine coating of matrix resin with one deck teflon.
The present invention is evenly sprayed on the matrix surface of impeller and is attached the fluorine coating that one deck teflon is a matrix resin; English name is Teflon; Because the cause of pronunciation, what claimed Furtulon molecular formula picture usually again is the rich dragon of Furtulon, iron, the rich dragon of iron, fe fluon or the like; This fluorine coating is a kind of high-performance coating, in conjunction with heat resistance, non-viscosity, chemical inertness and sliding, on the matrix surface of impeller, forms one deck nonporous film, realizes not sticking effect.The present invention is on the matrix surface of wheel disc and wheel disc, and the technique effect that etching evenly distributedly has many wave grooves to bring is that one side improves combination force, can prevent that fluorine coating from causing obscission under the blade dither that the impeller high speed rotating is produced; On the other hand, utilizing the impeller high speed rotating is that wave groove produces the disturbance gas-bearing formation at wheel disc and blade surface; Alleviate the blade collision energy of oil smoke and high speed rotating, produced the unexpected oil tech effect of keeping away.
In sum, the present invention and existing technology compare, and coating is combined, and are not easy to come off, and make simple.Impeller can not attach grease at work, realizes exempting from not unpick and wash stickingly oil.
Description of drawings
Figure l is a structural front view of the present invention.
The A portion zoomed-in view that Fig. 2 for figure l is.
Label declaration among the figure: 1 wheel disc; 2 blades; 3 wave grooves; 4 fluorine coatings.
Embodiment
Knot accompanying drawing and embodiment further specify the present invention below.
A kind ofly exempt to unpick and wash the non-stick oil ventilator impeller, comprise the blade 2 on wheel disc 1 and the wheel disc; It is characterized in that: on the matrix surface of wheel disc 1 and blade 2, etching evenly distributedly has many wave grooves 3; Filling spray on the groove face is the fluorine coating 4 of matrix resin with one deck teflon; The cross section of described wave groove 3 is a triangular groove.
A kind ofly exempt to unpick and wash the non-stick oil ventilator impeller, comprise the blade 2 on wheel disc 1 and the wheel disc; It is characterized in that: on the matrix surface of wheel disc 1 and blade 2, etching evenly distributedly has many wave grooves 3; Filling spray on the groove face is the fluorine coating 4 of matrix resin with one deck teflon; The cross section of described wave groove 3 is a triangular groove.
