Abstract

The utility model relates to an oil collecting screen which is used to be installed on the air inlet of a fume exhauster, belonging to the purification equipment of the kitchen. The oil collecting screen comprises a cone shaped outer cover and an oil filter screen, the outer cover is a cone shaped cover body whose upper end is open, the cone surface is provided with inhalation holes which are arranged in rows, and the bottom plate of the outer cover is provided with an oil outlet hole which is communicated with an oil collecting cup; the cone shaped oil filter screen is composed of a big upper ring rack, a small lower ring rack and a plurality of arc oil guiding plates which are connected between the upper ring rack and the lower ring rack, and each arc oil guiding plate is arranged between the two ring rack in gap way; each arc oil guiding plate is one-to-one correspondingly positioned on the inside of each row of fume inhalation holes. The arc oil guiding plates make the oil fog be easy to be gathered and separated, and the oil collecting screen uses the gaps of the oil guiding plates to substitute the traditional small mesh holes, which solves the problem that the small mesh holes are easy to be clogged by the oil droplets and ensures the expedite air circuit.

Description

Oil-collecting mesh

Technical field

The utility model relates to a kind of oil-collecting mesh that is used for range hood, belongs to cleaning equipment.

Figure viewed from behind technology

At present, range hood is many to be provided with oil-collecting mesh at air inlet, and this oil-collecting mesh generally is made up of the outer cover and the inner cover of taper, outer cover is the cone-shaped hood frame that is welded into by bonding jumper, inner cover is the filament oil cleaner screen, is close to the inboard of cone-shaped hood frame, and the two forms oil-collecting mesh.The oil smoke that the kitchen produces is aspirated by range hood, and mist of oil wherein is gathered into oil droplet through the oil cleaner screen collision, and oil droplet flow to downwards in the cover lubricating cup at the end along the conical surface, and flue gas then continues to rise to blast pipe and discharges outdoor.Because oil cleaner screen is crisscross network structure, not only oil circuit is not smooth, and the oil droplet of thickness influences the mesh obstruction suction effect, so need often more renew filter screen this being easy on the net.

Summary of the invention

The purpose of this utility model provides a kind of oil-collecting mesh, and it can overcome the shortcoming that existing oil-collecting mesh exists, and oil strain is effective and the flue gas suction path is unimpeded, be difficult for stopping up.

This oil-collecting cigarette guard is made up of the outer cover and the oil cleaner screen of taper, and outer cover is the back taper cover body of upper end open, the otic placode that is connected with the range hood air inlet that is provided with suitable for reading, and the conical surface has arranged in column inlet hole, and the outer cover base plate is provided with oil outlet; The taper oil cleaner screen is by last big, little two circle framves and be connected in several oil guide plates that enclose up and down between the frame and form down, and said oil guide plate is the arc lath, is arranged in two each arc interspace and encloses between the framves.Each arc oil guide plate is positioned at the inboard with each row oil smoke inlet hole correspondingly.

Said oil smoke inlet hole is the waist-shaped hole to in-flanges.Insert respectively in the arcuate socket that encloses frame up and down at the two ends up and down of said arc oil guide plate, and the end bending is fixed.The following circle frame of oil cleaner screen and outer cover base plate are respectively equipped with the location concave, convex groove that coincide mutually, make oil cleaner screen in outer cover position decided at the higher level but not officially announced.

In the utility model, oil cleaner screen replaces the woven wire of traditional cross structure with the strip arc oil guide plate of gap arrangement, mist of oil is easily assembled, fluid flows downward smooth and easy along cancave cambered surface, replace traditional grid aperture with the arc strip sheet separation, solved the grid aperture easily by the oil droplet blocking problem, can guarantee that gas circuit is unimpeded.Outer cover and oil cleaner screen adopt stainless steel or make through the metal that face coat is handled, and clean very conveniently, need not replacing.

Among each figure, wherein, the 1-range hood, 2-the utility model oil-collecting mesh, 21-outer cover, 21-1-oil smoke inlet hole, 21-2-outer cover otic placode, 21-3-lubricating cup bayonet socket, the 21-4-oil outlet, 21-5-locatees tongue and groove, the last circle of 22-frame, 23-arc oil guide plate, 24-be the circle frame down, the 25-arcuate socket, 3-catchment cup, 4-lubricating cup hook.

Fig. 1 represents that the utility model oil-collecting mesh 2 is installed on the air inlet of range hood 1, and the otic placode 21-2 (see figure 5) of outer cover is used for and is connected and fixed in the air intake import.Among Fig. 1, oil-collecting mesh 2 is expressed as vertically analyses and observe state, and the lower end of oil-collecting mesh 2 is connected to catchment cup 3.

As Fig. 1, this oil-collecting mesh 2 is by outer cover 1 and include the oil cleaner screen that encloses frame 22, arc oil guide plate 23, encloses frame 24 down and form, oil cleaner screen places in the outer cover 21, it is fixed in up and down by arc oil guide plate 23 and forms between two circle framves 22,24, their annexation is seen Fig. 5, Fig. 6 and Fig. 7: on enclose frame 22 and down circle frame 24 have arcuate socket 25, insert respectively in the arcuate socket 25 that encloses frame up and down at the two ends up and down of arc oil guide plate 23, subsequently with the fixing (see figure 7) of end bending.The structure of outer cover 21 is seen Fig. 8, and Fig. 8 represents that the taper wall of outer cover 21 has the oil smoke inlet hole 21-1 of waist type; From Fig. 2, Fig. 3 and Fig. 4 as seen, the inlet hole 21-1 of outer cover 21 is to the in-flanges hole; From Fig. 2, Fig. 3 and Fig. 4 as seen, each arc oil guide plate 23 of oil cleaner screen is positioned at the inboard of outer cover, and with each row inlet hole 21-1 corresponding (Fig. 2, Fig. 4).

Fig. 6 be the B of Fig. 1 to view, what show among the figure is the base plate of taper outer cover 21, has two oil outlet 21-4 on this base plate, the fluid that flows down from arc oil guide plate 23 enters the catchment cup 3 from this oil outlet.Base plate is provided with 21-3 lubricating cup bayonet socket, can link up with 4 by lubricating cup and be connected (referring to Fig. 1) with catchment cup 3, and the bayonet type lubricating cup is usefulness better, can take down the both hands of can not making dirty once changeing conveniently.In addition, among Fig. 6, the outer cover base plate represents to locate recessed (or protruding) groove by two stain 21-5 of both sides of the edge, they coincide with circle frame 24 protruding (or recessed) groove is corresponding down, make oil cleaner screen in outer cover position decided at the higher level but not officially announced, simultaneously guarantee that also each arc lath 23 of oil cleaner screen is corresponding one by one with the position of each row waist type inlet hole 21-1 of outer cover 21, can not misplace.

When range hood is worked, kitchen fume enters this oil-collecting mesh from the oil smoke inlet hole 21-1 of outer cover 21, oil smoke behind the hand-hole promptly makes contained mist of oil gather into oil droplet with arc oil guide plate 23 collisions of oil cleaner screen, oil droplet flow to the bottom of outer cover because of the gravity effect downwards along the cancave cambered surface of oil guide plate 23, is collected by catchment cup by oil outlet subsequently; Filtering the flue gas of most of mist of oil take off the air inlet that enters smoke exhaust from the gap between the oil guide plate, and continue to rise, to the range hood outlet, discharge outdoor by blast pipe.
