Abstract
The utility model discloses an exhaustion multiplier, which comprises an outer housing, an air shield, a blower, a wind pipe and an oil cup, wherein the lower part of the outer housing presents in a bell-mouthed shape which is convenient for covering a hearth as much as possible, the air shield is arranged at the inner side of the outer housing, the upper part of the blower is connected with the wind pipe, and the wind pipe is provided with a secondary air inlet. Since the wind pipe is provided with the secondary air inlet, the smoke inside the wind pipe produces a suction force during the flowing so as to drive the oil smoke inside the air shield to be discharged together with the smoke which is discharged by the blower through the secondary air inlet, thereby the oil smoke discharging effect can be realized. The exhaustion quantity of the range hood is calculated to be improved by 1.5 times under the condition that the original power is not changed, so the efficiency of the range hood is improved, and the effect of energy conservation and oil-smoke pollution reduction can be realized.
Description
Technical field
The utility model belongs to the daily life field of energy-saving technology, relates in particular to the energy-efficient exhaust enhancing device of a kind of range hood.
Background technology
The exhausting type range hood is installed on cooking stove top, rotate by the impeller in the Motor Drive volute in the body, form certain negative pressure in the air inlet zone, drainage by smoke collecting chamber, thereby above cooking stove, form negative pressuren zone in certain spatial dimension, its peripheral soot gas is subjected to vacuum suction to arrive filter screen, filter to isolate a part of bulky grain mist of oil, remaining gas enters the centrifugal blower system of cigarette machine inside, through the high speed rotation of draught fan impeller, soot gas is subjected to action of centrifugal force and is thrown out of impeller, carries out oil smoke once more and separates, the oil of separating flows into lubricating cup through the Oil Guide system, and flue gas after being purified is discharged outdoor along airduct.Existing range hood oil suction mouth majority is in the centre position of range hood, and gas range is generally two kitchen range eyes, therefore put when pot cooking when a kitchen range eye, the range hood of ability oil suction cigarette in the middle of having only, can not well siphon away oil smoke, smoking is not thorough, wants to improve the efficient of range hood, must improve the power of blower fan, so just increase power consumption.
Summary of the invention
The purpose of this utility model is exactly at the halfway problem of existing range hood fume exhaust, provides a kind of under the prerequisite that does not increase power of fan, by changing the structure of airduct, to improve the operating efficiency of range hood.
The purpose of this utility model is achieved through the following technical solutions, this exhaust synergistic device comprises outer cover, kuppe, blower fan, airduct, lubricating cup, described outer cover bottom becomes toroidal, so that more covered the kitchen range top, described outer cover inboard is provided with kuppe, described blower fan top is connecting airduct, the described secondary air mouth that is provided with on airduct.
Secondary air mouth on the described airduct is a circumferential apertures.
Described secondary air mouth is for being distributed on the wind pipe wall a plurality of circular holes on the same circumference.
Described secondary air mouth is to be distributed in two relative on wind pipe wall circular holes, and the orientation of two circular hole is corresponding mutually with the gas range of two kitchen range eyes.
Soot gas is subjected to action of centrifugal force and is thrown out of impeller through the high speed rotation of draught fan impeller, carries out oil smoke once more and separates, and the oil of separating flows into lubricating cup through the Oil Guide system, and flue gas after being purified is discharged outdoor along airduct.Flue gas in the airduct produces draft when mobile, discharge with the flue gas of blower fan discharge through the auxiliary air inlet port thereby drive the interior oil smoke of kuppe, to reach the effect that increases mist extractor.
Exhaust synergistic device described in the utility model also can be applicable on numerous air discharging facilities such as fire-fighting blower fan, toilet exhaust blower, air blast.
The beneficial effects of the utility model: owing on airduct, be provided with the secondary air mouth, flue gas in the airduct produces draft when mobile, thereby the flue gas that the oil smoke in the drive kuppe is discharged with blower fan through the auxiliary air inlet port is discharged, to reach the effect that increases mist extractor.Through calculating, range hood can increase as for 1.5 times capacity under the constant situation of former power, has improved the efficient of range hood, the effect that reached energy-conservation, reduces fume pollution.
