Description
The present invention relates to screen pack, particularly be used in the composite filter net of smoke exhaust ventilator, this composite filter net is installed in kitchen range tops, and is outdoor the waste gas discharge that contains oil smoke and steam of generation the frying pan from kitchen range etc.
That is to say, this smoke exhaust ventilator 20, catch a part of oil smoke of rising from frying pan etc. by screen pack liquefaction, simultaneously remainder is discharged outdoorly, catching a part of oil smoke by screen pack is one of critical function of this smoke exhaust ventilator 20.If all discharge is outdoor with oil smoke, then not only the oil of liquefaction will hang and the external wall of making dirty the next-door of also can making dirty along pipe blackly.
Mostly employed in the past smoke exhaust ventilator is punched-plate (being the ventilative plate of going out many holes on metal plate) or the screen pack that only 1～2 piece of wire netting is overlapped and forms with screen pack, and the seizure power of oil smoke is not very desirable.This formation in the past, the existence of screen pack has become the obstacle of exhaust on the contrary, wants by the abundant exhaust of screen pack, just must adopt sizable attraction fan.
Yet, the present inventor has developed a kind of gyroaxis two ends at motor recently and has been respectively equipped with the multiple-blade ring-type fan, by improving the exhaust channel in the smoke exhaust ventilator, make to attract the fan miniaturization to make it have sizable attraction simultaneously, also begin to have carried out the opening of the screen pack that this powerful smoke exhaust ventilator uses.That is to say, owing to attract the raising of the attraction of fan, must consideration carry out the seizure and the liquefaction of oil smoke effectively.
So how the present inventor can form more efficiently screen pack to the screen pack that is used in this smoke exhaust ventilator and do all investigations.Found that, on screen pack, form the passage of the oil flow liquefied energetically, can bring good result, thereby finish the present invention.
The present invention In view of the foregoing realizes that problem to be solved is: develop a kind of screen pack that can fully liquefy and catch oil smoke and can keep its aeration.
That is, the object of the present invention is to provide a kind of screen pack simple in structure,, and can fully carry out the seizure of oil smoke in use even long-term the use can not damaged aeration yet.
For solving above problem, the technical solution used in the present invention will use symbol to describe in embodiment explanation described later.
A kind of composite filter net for kitchen ventilator 10 is provided, these composite filter net for kitchen ventilator 10 dismounting are contained in the attraction mouth 21 of smoke exhaust ventilator 20 freely, liquefaction is also caught by the things such as oil smoke in the waste gas of these smoke exhaust ventilator 20 attractions, it is characterized in that, comprising: about each 1 piece and middle 1 piece, amount to 3 pieces of flat flat panel filter nets 11,12,13 that have many meshes; At least two pieces of corrugated plating screen packs 14 are clipped between these flat panel filter nets 11,12,13, are the corrugated plate shape that has many meshes; Framework 15 is fixed the neighboring of these corrugated plating screen packs 14 and described each flat panel filter net 11,12,13, and the oil smoke etc. with the liquefaction of making flows or with the oil storage passage 16 of its storage.
That is to say that composite filter net 10 of the present invention is in the dismantled and assembled as shown in Figures 2 and 3 smoke exhaust ventilator 20 that is installed in formation kitchen system 100 as shown in Figure 1 freely.As Fig. 6-shown in Figure 8, be followed successively by by outer (in the face of gas range 30 sides): outer flat panel filter net 11, corrugated plating screen pack 14, middle flat panel filter net 13, corrugated plating screen pack 14 and interior flat panel filter net 12 amount to 5 pieces and are composited.
Here importantly, 2 pieces of wave plate filter nets 14 that clipped by outer flat panel filter net 11 grades of " flat board " shape are as employing " corrugated plating shape " as described in the literal.If these corrugated plating screen packs 14 are writing board shapes, even each screen pack has blow vent also can fit tightly mutually.Because each corrugated plating screen pack 14 is a corrugated plating, promptly have as Fig. 6～linear corrugated part 14a shown in Figure 8, because each corrugated part 14a, and just formed the path that forms because of corrugated part 14a between the screen pack of adjacency.
The path that is formed by corrugated part 14a has the two-layer meaning: the one, as Fig. 7, shown in Figure 8, it is the path that the oil droplet that liquefied flows that is captured, oil droplet flow away the back it just become the path of exhaust-gas flow again.For this reason, the corrugated part 14a of each corrugated plating screen pack 14 preferably is upper and lower to configuration, as long as oil droplet flows, then each corrugated part 14a is skewed and also can.In addition, the corrugated part 14a of 2 pieces of corrugated plating screen packs 14 is upper and lower to the then best results that distributes, and making wherein at least, the corrugated part 14a of 1 piece of corrugated plating screen pack 14 is upper and lower to configuration.
Because these corrugated plating screen packs 14 are fixing with the framework 15 that has oil storage path 16 with the outward flange of each flat panel filter net 11,12,13, so be connected in the corrugated part 14a of each corrugated plating screen pack 14 and this framework 15.Therefore, the oil droplet that has been liquefied can arrive oil storage path 16 in framework 15 by each corrugated part 14a.
Certainly, outer flat panel filter net 11, corrugated plating screen pack 14, middle flat panel filter net 13, corrugated plating screen pack 14 and interior flat panel filter net 12, amount to 5 pieces of screen packs, can be the screen pack that is formed with the punching that is used to ventilate on flat board separately, also can be the screen pack of being worked out by wire rods such as wires.But in order to form the oil droplet flow passage, must form corrugated part 14a on each corrugated plating screen pack 14.In order to reduce the thickness of these composite filter net 10 integral body, outer flat panel filter net 11, interior flat panel filter net 12 and middle flat panel filter net 13 must be tabulars.
If the composite filter net of the present invention 10 of above formation is installed in attraction mouth 21 places of smoke exhaust ventilator 20, make the attraction fan running of smoke exhaust ventilator 20, then oil smoke of generation such as gas range 30 etc. will attracted in the smoke exhaust ventilator 20 by composite filter net 10.When oil smoke passes through this composite filter net 10, by outer flat panel filter net 11 grades that constitute composite filter net 10 with the oil smoke cooling liquid, the oil smoke that has been liquefied becomes little oil droplet earlier and adheres on outer flat panel filter net 11 grades, because the surface tension that oil is had, little oil droplet rolls up big oil droplet gradually.After becoming larger oil droplet,, and accumulate in and the contacted position of each screen pack again because its minute surface tension force.Then, when surface tension during less than gravity, oil will form oil stream by corrugated part 14a, finally flow in the oil storage path 16 in the framework 15.
Flow to oil in the oil storage path 16 in the framework 15 by corrugated part 14a, can be stored in the oil storage path 16 at that, but in embodiment as described below, as shown in Figure 7, the part of this oil storage path 16 is formed with opening 16a, and oil droplet will flow in the oil conservator (not shown) of a big volume that is provided with in the main body of smoke exhaust ventilator 20 by this opening 16a.This oil conservator can remove from smoke exhaust ventilator 20, so can at any time this oil conservator be unloaded, oil is wherein outwelled.
Flowing of the oil that as above has been liquefied is not all to take place at each corrugated part 14a all sites certainly, but stores up generation when a certain amount of when oil.At ordinary times, each corrugated part 14a will form the exhaust passage.And comprise outer flat panel filter net 11 and can catch oil droplet at the interior screen pack that amounts to 5 pieces, so can not making, the oil of each screen pack takes place stifled on the screen pack.And outer flat panel filter net 11 waits each screen pack owing to the corrugated part 14a that corrugated plating screen pack 14 is had keeps at a distance, so the oil that has been liquefied can firmly not be bonded on each screen pack.That is, the oil of liquefaction will flow away by each corrugated part 14a at any time, so can keep the aeration of each outer flat panel filter net 11.
So,, and can fully catch oil smoke when using even long-term use of composite filter net of the present invention 10 can not damaged its aeration yet.
