Abstract
The utility model relates to a kitchen fume exhauster, which adopts a guide type to avoid or reduce the pollution of fume to a blower. The shape of the utility model relates to an oblong shell body which is divided into an upper layer and a lower layer. The utility model is mainly composed of a blower, a static pressure box, a nozzle plate, a flue, a wind guide plate, a cover shell, a lighting lamp, a switch, etc., wherein, the blower and the static pressure box are arranged in the cover shell of the upper layer; one end of the static pressure box is connected with the opening of the blower, and the other end is connected with the nozzle plate; a wind inlet of the blower bypasses the fume zone; once wind is sprayed by a nozzle in a high speed; fume (second wind) is exhausted out of the room by utilizing a jet vacuum absorption principle.
Description
The utility model relates to a kind of kitchen oily fume exhauster, can alleviate effectively to avoid the pollution of oil smoke to blower fan, is convenient to clean.
Present known oil-containing air exhauster for kitchen all is a straight-line, and blower fan directly contacts oil smoke and causes severe contamination, and especially draught fan impeller is complex-shaped, cleans difficulty.
The purpose of this utility model provides a kind of smoke exhaust, and it can not only effectively get rid of oil smoke, and can avoid or alleviate the pollution of oil smoke to blower fan.
The purpose of this utility model is achieved like this, and it changes into induction type with traditional straight-line, and air inlet is located at the smoke exhaust top or directly is connected to outdoor.The blower fan exit connects plenum chamber, one time wind is gone out by nozzle ejection after the plenum chamber supercharging, and speed can reach 20m-30m/sec, because the vacuum suction effect around the jet, the oil smoke (secondary wind) that accumulates in the enclosure is sucked, mix the back with a wind and discharge from exhaust outlet.Generally speaking, induction ratio (secondary air flow/primary air flow) can reach 2.5-5.If primary air flow is 4m
3/ min, induction ratio is 4, then secondary air flow (mist extractor amount) can reach 16m
3/ min can be not less than the capacity of smoke exhaust on the existing market.
Owing to taked such scheme, alleviate effectively or avoided the pollution of oil smoke blower fan, make things convenient for the user to clean.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing 1 is vertical section structure figure of the present utility model.
Accompanying drawing 2 is cross section structure figure of the present utility model.
In accompanying drawing 1 and the accompanying drawing 2: 1. blower fan, 2. plenum chamber, 3. nozzle plate, 4. flue, 5. wind deflector, 6. case, 7. illuminating lamp, 8. switchboard.
In accompanying drawing 1 and accompanying drawing 2 illustrated embodiments, 6. case is cuboid, and two-layer about dividing, the header board end opening slightly upwards improves, and is welded by the sheet metal compacting.Blower fan 1., 2. plenum chamber be positioned at the upper strata case, isolates with oil smoke.1. blower fan adopts low noise efficient centrifugal blower fan, its performance must be able to satisfy the jet hole wind speed (20～30m/sec) and air quantity (greater than 4m
3/ min) requirement.2. plenum chamber is a rectangular box body, and the one end is connected with the blower fan exit, and 3. the other end is connected with nozzle plate.1. blower fan uses bolting on base, and uses the rubber blanket damping.Air inlet is located at case top, upper strata, rear portion or other any zone of avoiding oil smoke, also can be connected to outdoor.3. nozzle plate is loaded on 2. left side of plenum chamber, is provided with the notch of band gradient on plenum chamber, and 3. nozzle plate inserts in the notch, and it is slotting more tight more when inserting to make progress, and nozzle plate 3. below also is provided with elastic circlip, can realize the elastic compression location.3. nozzle plate is provided with nozzle, and in general, nozzle length L is 3～4 with the ratio of aperture D, and aperture D is not more than 12mm, and total air-out area is greater than 2300mm
2, nozzle can divide three rows, and dislocation is arranged.5. wind deflector is rectangle, middle grizzly bar for the band gradient, and the frame place is provided with oil trap all around, is installed on the position of lower floor case top, nozzle plate below, is designed to elastic insertion type, is convenient to mounting or dismounting.Flue is 4. by sheet metal compression moulding, 6. welds with case to be one.7. illuminating lamp is loaded on lower floor case top, and 8. switchboard is loaded on the case header board, is embedded.Be equipped with valve at the upper strata case with respect to the position of blower fan and illuminating lamp, with convenient maintenance.
Claims (1)
1. oil-containing air exhauster for kitchen, external form is rectangular housing, divide two-layer up and down, it mainly is made up of blower fan, plenum chamber, nozzle plate, flue, wind deflector, case, illuminating lamp, switchboard etc., it is characterized in that: blower fan and plenum chamber are positioned at the upper strata case and oil smoke is isolated, and plenum chamber one end links to each other with the blower fan outlet, and the other end links to each other with nozzle plate, air inlet is avoided the oil smoke district, and lower floor case top is provided with wind deflector.
