Abstract

The invention provides an oil filtering impeller of a range hood. The oil filtering impeller comprises an impeller (1), a filtering net (2) and a connection screw (3). The technical innovation point is that the filtering net (2) is fixedly disposed on one end face of the impeller (1) by using the connection screw (3). With the adoption of the structure of directly and fixedly connecting the filtering net (2) with the impeller (1), when the impeller (1) rotates to work, negative pressure in a cabinet air flue is established so that a lot of lampblack at the exterior can be sucked; meanwhile, the sucked lampblack collides with the filtering net (2) mounted on the end face of the impeller (1), so that the lampblack is separated; and therefore, a motor which singly drives the filtering net to rotate is saved, the noises are reduced, the cost is saved and a mounting space is reduced.

Description

A kind of grease filtrating impeller of range hood

One, technical field

The present invention relates to install the grease filtrating impeller of a kind of range hood of grease separate mesh on the impeller of range hood.

Two, background technology

2011.10.31. State Administration for Quality Supervision and Inspection and Quarantine and national standardization administration committee have issued the new national standard (GB/T17713-2011) of range hood, and came into effect from February 1 last year, one of content increasing in new national standard is: normality odor reduction degree >=90% of exhausting type range hood, grease separating degree >=80%, according to my half a year of many experiments, detect, the static grease separate mesh of routine that discovery is arranged on impeller the place ahead is difficult to reach this standard, I have invented " range hood of device rotation grease separate mesh " (patent No.: 2012202632869) for this reason, met the requirement of new national standard to odor reduction degree and grease separating degree.But its defect is: rotating separation net and impeller separating device, and the driven by motor of two different capacities of needs, manufacturing cost increases, and noise increasing, takes up room larger when range hood is installed.

Three, summary of the invention

The present invention is directed to the defect of above-mentioned existence, the technical scheme of technical problem to be solved and proposition is: for reducing the cost of manufacturing range hood, reduce noise and reduce installing space, invention integrates the grease filtrating impeller of a kind of range hood of setting up range hood internal negative pressure and grease filtrating function.It comprises impeller, and grease filtrating net and attachment screw form; It is characterized in that with the affixed grease filtrating net being formed by twine, flange and reinforcement of screw on impeller one end face.Owing to adopting this screen pack is direct and structure that impeller is fixed together, therefore when this impeller and fume-exhausting owner machine shaft are mounted in the air channel in cabinet rotary work, it has set up the negative pressure in cabinet air channel on the one hand, the oil smoke of outside is inhaled in a large number, also make the oil smoke being inhaled into and the grease filtrating net being arranged on impeller end face bump simultaneously, oil smoke is produced separated, thereby saved separately the motor with electric filter, reduced noise, provided cost savings and dwindled installing space.

Four, accompanying drawing explanation

Fig. 1 is the grease filtrating blade wheel structure schematic diagram of a kind of range hood of the present invention.

In figure: 1, impeller; 2, screen pack; 2.1, silk screen; 2.2, flange; 2.3, reinforcement; 3, attachment screw.

Five, the specific embodiment

Below in conjunction with accompanying drawing, the implementation process of the grease filtrating impeller of a kind of range hood of the present invention is described further:

(1), manufacture process:

According to design drawing, manufacture the impeller 1 of certain diameter and the screen pack 2 matching with it, screen pack 2 use attachment screws 3 are fastened on an end face of impeller 1, just consist of the grease filtrating impeller of a kind of range hood of the present invention.

(2), use procedure:

The machine shaft that the grease filtrating impeller processing is arranged in air duct of range hood tightens, complete range hood is arranged on to the top, top (top-sucking kitchen ventilator) or front upper place (side extraction cooking fume extractor) of gas range in kitchen, connect circuit and smoke exhaust pipe, when culinary art starts just to press the control button on face plate of smoke exhaust ventilator, motor in air channel rotarily drives grease filtrating vane rotary, make generation negative pressure in lampblack absorber cavity, the oil smoke of outside is inhaled into directly and screen pack 2 bumps, oil smoke is produced separated, thereby the grease filtrating impeller of a kind of range hood of the present invention reaches separated oil smoke and the dual-use function that discharges oil smoke.After grease filtrating impeller is used a period of time, can unscrew easily the attachment screw 3 that connects screen pack 2 and impeller 1, the screen pack 2 of pulling down on impeller 1 cleans, after can again load onto use.

Claims (2)

1. the grease filtrating impeller of a kind of range hood of the present invention, it comprises impeller (1), screen pack (2) and attachment screw (3) form; It is characterized in that with the affixed screen pack of attachment screw (3) (2) on an end face of impeller (1).

2. the grease filtrating impeller of a kind of range hood as claimed in claim 1, is characterized in that screen pack (2) is comprised of twine (2.1), flange (2.2) and reinforcement (2.3).
