Description
Technical field
The utility model relates to a kind of Kitchen hygiene device, relates in particular to lampblack absorber, is specially a kind ofly without blade profile air amplifier formula, to exempt to unpick and wash lampblack absorber.
Background technology
At present, known lampblack absorber operation principle is: the vane rotary in the Motor Drive spiral case in body, entry zone at lampblack absorber forms certain negative pressure, by the drainage of smoke collecting chamber, thereby in certain spatial dimension, form negative pressuren zone above cooking stove, the soot gas of its periphery is subject to vacuum suction to arrive screen pack, filter to isolate a part of bulky grain mist of oil, remaining gas enters the centrifugal blower fan system of lampblack absorber inside, High Rotation Speed through draught fan impeller, the effect that soot gas is subject to centrifugal force is thrown out of impeller, oil smoke is separated again, the oil of separating flows into lubricating cup through Oil Guide system, flue gas after purification is outside airduct discharge chamber.
See therefrom, existing smoke exhaust ventilator has obvious shortcoming and defect: although 1. the screen pack of lampblack absorber has filtered out a part of oil smoke, but the inwall of lampblack absorber that also had a large amount of fume pollutions, cause a large amount of inhomogeneous long-pending oil of draught fan impeller, blower fan rotates disequilibrium, cause the effect of lampblack absorber worse and worse, its mechanical noise is also increasing; 2. lampblack absorber itself does not have effective purification means, and the complicated in mechanical structure of itself, when lampblack absorber internal cavity and impeller accumulate while having a large amount of greasy dirts, it is very difficult that the dismounting of lampblack absorber and cleaning become, need professional just can complete, sometimes after cleaning, effect is poor all the better, does not reach the effect of anticipation; 3. due to the defect of existing lampblack absorber furred ceiling design and be short of effective purification means, be the suction effect guaranteeing in a short time, its power is all higher (mainstream model power is all between 200W-250W) generally, very power consumption.Lampblack absorber has obtained universal in Chinese kitchen, but its afunction exist actually: 1, after long-time use, mechanical efficiency is poor; 2, cleaning is very difficult; 3, energy consumption is high, and these problems need to solve in time.
Summary of the invention
The utility model, in order to solve the problem that after the long-time use of existing lampblack absorber, mechanical efficiency is poor, cleaning is difficult, energy consumption is high, provides a kind of and has exempted to unpick and wash lampblack absorber without blade profile air amplifier formula.
The utility model is to adopt following technical scheme to realize: without blade profile air amplifier formula, exempt to unpick and wash lampblack absorber, comprise the air amplifier that is provided with at least one air pressurizing unit in housing and which is provided with gas feed, described air pressurizing unit comprises electric machine controller and is located at the switch on housing, housing top has air inlet and lampblack absorber outlet, housing bottom also has lampblack absorber import, the outlet of air amplifier and lampblack absorber exit seal overlap, the import of air amplifier and lampblack absorber inlet seal overlap, and in lampblack absorber outlet, are sealedly connected with smoke discharging pipe.
During work, press the switch of air pressurizing unit, air pressurizing unit is by the air inlet air amount on housing, the air being inhaled into becomes high-speed gas after air pressurizing unit supercharging, high-speed gas is entered in air amplifier by gas feed, through air amplifier, form high velocity air, according to the principle of air-flow entrainment effect, high velocity air enters smoke discharging pipe by the air of entrapped air amplifier inside by the outlet of air amplifier, therefore in lampblack absorber import department, form certain negative pressure and air-flow, oil smoke is just brought into and is discharged from outdoor by negative pressure and air-flow.
Air pressurizing unit and air amplifier are structure well-known to those having ordinary skill in the art.
Above-mentioned exempts to unpick and wash lampblack absorber without blade profile air amplifier formula, air amplifier forms around a circle airfoil body by a cylindrical shell with at cylinder inner surface, the leading edge point of airfoil body towards lampblack absorber importer to, the gas feed of described air amplifier is located at cylindrical shell bottom around cylindrical shell compartment of terrain.High-speed gas after air pressurizing unit supercharging enters cylindrical shell by the gas feed of cylindrical shell bottom, and forms annular high velocity air along airfoil body surface, annular high velocity air entrapped air effective, thus improved the effect that extracts oil smoke.
The longitudinal section of described airfoil body is aerofoil profile, and aerofoil profile is the known shape of those skilled in the art.
Above-mentioned exempts to unpick and wash lampblack absorber without blade profile air amplifier formula, in the cylinder lumen of air amplifier, be provided with soot gas sensor, the signal output part of soot gas sensor is connected with the electric machine controller of air pressurizing unit, and the change-over switch of controlling lampblack absorber auto state and artificial state is also housed on housing.
The connection line of change-over switch is that those skilled in the art easily realizes.
When change-over switch is chosen auto state, the soot gas sensor being provided with in inner chamber is controlled the rotating speed of motor in air pressurizing unit according to the uninterrupted of the soot gas detecting, realize the function of automatic frequency adjustment, oil smoke can be effectively extracted and energy consumption can be saved again, when the switch of walking around is chosen manual mode, press the switch of air pressurizing unit, lampblack absorber is with firm power work.
Above-mentioned exempts to unpick and wash lampblack absorber without blade profile air amplifier formula, and air amplifier consists of at least two air amplifiers of connecting from beginning to end.Can improve the effect that extracts oil smoke.
Above-mentioned exempts to unpick and wash lampblack absorber without blade profile air amplifier formula, and gas feed is bar formula spout.Bar formula spout easily enters in air amplifier high-speed gas, has improved the effect that extracts oil smoke.
The utlity model has following advantage: 1. in pump drainage cigarette channel, there is no motor or impeller, can not bring the problem that mechanical efficiency declines and noise increases because amassing oil pollution motor or impeller; 2. in pump drainage cigarette channel, there is no complicated frame for movement, can clean at any time, clean greasy dirt very convenient, really accomplished to exempt to unpick and wash; 3. the rotating speed of motor can be controlled according to the size of cooking fume flow, can effectively utilize electric energy; 4. owing to having applied aerodynamics principle, and existing lampblack absorber compares, and reaching under the prerequisite of taking out equally smoke discharging effect, and the electric energy consuming has reduced 1/3rd or 1/2nd.
