Abstract
The air curtain type fume exhaust device consists of mainly blower, annular air duct (or static pressure box), adjustable slot air supply port and peripheral air intake type or common fume exhaust ventilator. The device has the advantages of good oil fume exhaust effect, low energy consumption and low noise, and can be widely used in the industries of household and public meal cooking and the like.
Description
The utility model relates to a kind of smoke exhaust.
Existingly take out, smoke exhaust, form by hood and exhaust blower (centrifugal blower and axial flow blower) basically, its principle is to utilize exhaust blower to form negative pressuren zone in the hood bottom, thereby with in the oil smoke inhalation mask, discharges outdoor.But, according to fluid mechanics principle, outer certain any the air velocity of air entry roughly with this to square being inversely proportional to of air entry distance, like this, along with the distance between control point and the air entry increases, the wind speed of this point will be decayed rapidly.For example, the air mean flow rate of common eyes (two centrifugal blowers) extractor hood mouth is about 0.3～0.5 meter per second, cover mouthful from the distance on kitchen range top generally 1 close about, as calculated, the air velocity that affacts the kitchen range top edge has only 0.02～0.03 meter per second, because a cover mouthful setting height(from bottom) can not reduce arbitrarily, improving the smoke exhaust ventilator effect can only be flow and the pressure head that improves blower fan, yet being the very little power consumption that but causes, the effect that raising air quantity and pressure head can play increases, noise increases, simultaneously, the increase of capacity has also caused expending of other energy, as heating room and air-conditioned room.Though oil smoke can be considered thermal current, on the rise, in gastronomical process such as quick-fried, frying, oil smoke to around distribute in a large number, and not only upwards elegant.So existing taking out (row) lampblack absorber can not solve the problem of oil fume outer-runaway up hill and dale.
The purpose of this utility model provides oily fume exhauster a kind of better effects if, that energy consumption is low, noise is little.
Wind curtain type oily fume exhauster of the present utility model, constitute by pressure fan, air channel, air outlet, smoke exhaust ventilator and electric control system, it is characterized in that: the pressure fan air outlet joins with the looped duct (or plenum chamber) that is arranged in the kitchen range periphery, adjustable scrak type air outlet is arranged on looped duct (or plenum chamber) top, and smoke exhaust ventilator is installed in the kitchen range top.Air is sent in the looped duct after the pressure fan pressurization, blows out through the adjustable type air outlet again, forms ring-like jet, and oil smoke sealing ground is blown to extractor hood mouth bottom, oil smoke is discharged outdoor by exhaust blower at last.The air quantity of exhaust blower is 1.1～1.25 times of pressure fan air quantity, and is not excessive to guarantee oil smoke.
Smoke exhaust is peripheral intake type or plain edition, peripheral intake type smoke exhaust ventilator mainly is made up of centrifugal blower, inside and outside shell, exhaust opening and oil collecting system, space between the inside and outside shell forms the mist extractor passage, inside and outside shell lower periphery has oil trap, and is joined by oil guide pipe, and catchment cup is installed under the oil trap of shell angle, centrifugal blower is installed on shell upper central authorities, import is downward, and outlet is joined with exhaust opening, and the inner casing bottom can be furnished with light fixture.
Adjustable scrak type air outlet can be around its axis rotation, to guarantee the best angle of jet.
But the operating key centralized arrangement of electrical system also can be arranged respectively on the shell of smoke exhaust ventilator or kitchen range.
Pressure fan is a centrifugal fan, be installed in the kitchen range or kitchen range outside.
Looped duct (or plenum chamber) can be combined as a whole with kitchen range, also can arrange separately.
Because jet changes velocity field graded much smaller than air entry along the velocity gradient on its direction of advance, thus just oil smoke can be seen off with less air quantity, and with soot controlling in air curtain; Peripheral intake type smoke exhaust ventilator air intake cross section so air quantity is much smaller under identical wind speed, also helps the formation of air curtain less than the plain edition smoke exhaust ventilator simultaneously.
So the utility model total blast volume and power consumption be all less than the plain edition smoke exhaust ventilator, have effectively, energy consumption is low, and the advantage that noise is little can be widely used in family and public meal industry such as cook a meal.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the shape schematic diagram of first embodiment of the utility model.
Fig. 2 is the vertical view of first embodiment kitchen range.
Fig. 3 is the upward view of first embodiment smoke exhaust ventilator.
Fig. 4 is the profile of Fig. 2.
Fig. 5 is the profile of the adjustable scrak type air outlet of first embodiment.
Fig. 6 is the profile of Fig. 3.
Fig. 7 is the schematic appearance of second embodiment of the utility model.
Fig. 8 is the vertical view of second embodiment kitchen range.
Fig. 9 is the profile of Fig. 8.
As shown in the figure, first embodiment is suitable for the utility model and kitchen range are the approved product of one.Pressure fan 1 will be sent into after the air pressurized in the ring-type plenum chamber 2 that is combined as a whole with kitchen range 15, blow out through adjustable scrak type air outlet 3, form annular jet, oil smoke is delivered to peripheral intake type smoke exhaust ventilator bottom, be inhaled into exhaust blower 6 by inner casing 4 and the air that shell 5 forms, after exhaust opening (and smoke pipe) 7 is discharged outdoor; Sealed casing pipe 18 plays a part ignition device 16 and ring-type plenum chamber 2 are isolated; Burner 17 is closed in the annular jet; The waste oil that the oil trap of inner casing 4 is collected flows in the catchment cup 9 in oil guide pipe 8 flow to the oil trap of shell 5 at last; Lighting 11 is installed in inner casing 4 bottoms, and in diffusing glass sheet 10 it being sealed in; Electrical control key 13 can be distinguished or control pressure fan 1 simultaneously, the high, medium and low shelves of the switch of exhaust blower 6 and light fixture 11 and air quantity; Lampblack absorber and pressure fan 1 a shared power supply and plug 14.Fin 12 works the adjustable slip diffuser effect of reinforcing.
Second embodiment is suitable for existing (row) soot device of taking out of the utility model transformation.Pressure fan 1 will be sent into looped duct 19 after the air pressurized, bar seam 24 through portion mounted thereto, air is blown out, form annular jet, looped duct 19 segmentations are installed between two siphunculus seat 20 and the threeway base 21, and can freely rotate around its axis, to regulate suitable flow angle, oil smoke and hot gas that common kitchen range 23 produce are sealed and take away by annular jet, discharge outdoor through plain edition smoke exhaust ventilator 22, power supply and plug 14 are used for switch pressure fan 1, also can add arrangements for speed regulation in addition; Support 25 connects base 20,21 one and fixes it.
