Description

A kind of filter screen of range hood

Technical field

The utility model relates to a kind of filter screens, and in particular to a kind of filter screen of range hood.

Background technique

Range hood is the smoke evacuation tool being arranged on kitchen range in kitchen, it can drain the flue gas that cooking generates, and is protected Hold the cleaning of air in kitchen.But with increasingly stringent, the kitchen fume of the reinforcement of present environmental consciousness and environmental protection supervision It is a large amount of discharge influence increasingly to be concerned caused by environment, especially for the dining room restaurant of some commercial operations, often It is required that the oil smoke of discharge is effectively treated, or even some is punished because oil smoke discharge is unqualified.It is generally set on range hood One layer of filter screen is set, oil smoke a part when passing through strainer is condensed to form liquid oil and be collected.It but is generally now single Layer strainer, is not thorough filtering oil smoke, so that also having excessive grease stain flue gas in the oil smoke excluded.

Utility model content

The purpose of the utility model is to provide a kind of filter screen of range hood, which can effectively filter flue gas, The grease stain contained in flue gas is filtered out, the pollution to extraneous gas is reduced.

To achieve the above object, the utility model takes following technical scheme:

A kind of filter screen of range hood, including outer net, which is characterized in that middle net is equipped with above the outer net, in it is online Fang Anyou Intranet, outer net and it is interior be provided with elongated ventilation hole on the net, in be provided with oval hole array on the net, in the oval hole array Elliptical aperture long axis length is 2~3 millimeters, and the outer net, middle net and Intranet are aluminum net.

Preferably, the outer net is there are upward outer net edge, and there are downward Intranet edge, Intranet edges for the Intranet In outer net edge, and it is bolted, it is online outside to be also equipped with snap-gauge.

In above-mentioned technical proposal, outer net, middle net and Intranet are aluminum net, and oil smoke is sequentially passed through from outer net to Intranet, and It is condensed on the net in each layer, because of aluminum net rapid heat dissipation, the tiny oil droplets in flue gas pool liquid by rapid condensation.In it is online Oval air hole eyelet is smaller, and the elongated ventilation hole eyelet of two sides outer net and Intranet is big, can take into account flue gas velocity in this way And condensation effect, make to discharge fume unobstructed, while condensation effect might as well.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is outer net structural schematic diagram；

Fig. 3 is middle web frame schematic diagram.

Specific embodiment

With reference to the accompanying drawing, the utility model is described further:

As shown in Figure 1, Figure 2 and Figure 3, the filter screen of this range hood includes outer net 1, middle net 2 and Intranet 3, and outer net 1 is aluminium Matter net, thereon there are elongated ventilation hole, ventilation hole is generally round rectangle shape, is arranged side by side, and runs through entire outer net.Outside The edge of net is there are outer net edge 111, and there are screw holes 112 on outer net edge, and for penetrating screw, outer net one end is also equipped with snap-gauge 113, entire filter screen can be installed on range hood by snap-gauge 113.Middle net 2, middle net choosing are installed above outer net With the preferable aluminum net of radiating, many elliptical apertures 211 are provided on middle net 2, in general, the long axis length of each elliptical aperture is 2~3 Millimeter, elliptical aperture 211 lines up array, when oil smoke, which passes through in outer net arrival, to be netted, the grease stain that contains in flue gas can be quick It is largely condensed into liquid, reduces the pollution to extraneous gas.The top of middle net 2 is equipped with Intranet 3, in Intranet 3 there are with it is outer The poroid ventilation hole 312 of the corresponding round rectangle of Netcom's air holes array, two sides outer net and the elongated ventilation hole eyelet of Intranet are greatly simultaneously And be correspondingly arranged, it is used with the lesser elliptical aperture array combination of middle net diameter, flue gas velocity and condensation effect can be taken into account, make to arrange Cigarette is unobstructed, while condensation effect might as well.There are downward Intranet edge 313 in Intranet 3, there are screw holes on Intranet edge 311 311, outer online outer net edge 111 is set up, and in filter screen assembling, Intranet edge 313 is placed on the interior of outer net edge 111 Side, middle net are located at the centre of intranet and extranet, and blending bolt sequentially passes through outer online screw hole 112 and interior online screw hole 311, then Intranet and extranet are fixed together and then carry out oil smoke separation.

Above-described embodiment is the explanation conceived to the utility model and realized, is not intended to limit it, in the present invention Under design, without the technical solution that substantially converts still in protection scope.
