Abstract
The utility model is a spin-flow vent fan, by using swirling flow forming low pressure kernel to generate powerful pumping capability, to pump oil fume. Clean air is put into a hydrocyclone 7 through a wind entering cylinder 3 by an exhaust fan 2, swirling flow is formed and reelingly rise along a spin-flow cylinder 5, then powerful pumping force is generated to pump the oil fume around the lower port of an air collection fan 9 at the lower part of an air entering fan 6 into an air exhausting fan 4, then the oil fume is pumped out of the room. The oil fume pumped by the utility model does not flow through fan impeller, therefore thoroughly eliminating many shortcomings of the prior vent fan. The utility model has the advantages of high efficiency of oil fume pumping, stable performance of the exhaust fan, low noise, convenience for cleaning, energy and electricity saving, etc. The utility model can not only be used to pump oil fume in kitchen, but also be used to pump (absorb) other gases, and can be widely used.
Description
The utility model is a kind of spiral-flow type smoke exhaust ventilator, is to utilize swirling eddy, forms the principle that the low pressure core produces powerful suction capactity, a kind of device of pump drainage oil smoke.
Existing smoke exhaust ventilator is made up of blower fan, flue, petticoat pipe, and blower fan is arranged in the flue, and the blower fan rotation is drawn into the blower fan of flowing through in the flue with oil smoke, directly is discharged to outdoor from flue by blower fan.Blower fan is installed in the flue, and during work, draught fan impeller rotation directly is drawn into oil smoke in the flue and discharges, and in this structure, the oil smoke impeller of flowing through is directly blown out by impeller.Mainly there is following defective in this smoke exhaust ventilator:
1. be arranged in the flue owing to blower fan, the pump drainage oil smoke of directly drying, blower fan itself is the blowing form directly, causes air-flow not smooth, influences the pump drainage ability, and oil fume pumping-clean rate is not high.Even the increasing power of fan, its effect is also not obvious.
2. the oil smoke draught fan impeller of flowing through, tobacco tar very easily precipitates and accumulates in blade surface, has destroyed the shape of blade, and the balance of surface smoothness and impeller must cause fan performance to descend, and air quantity reduces, and noise increases, and oil fume pumping-clean rate descends.
3. because the restriction of service condition and structure, petticoat pipe is 700-800mm apart from the distance of the kitchen range top, must cause the air-flow short circuit, and flue gas is excessive, makes the oil smoke can not emptying.Even adopt deep hood type, strengthen power of fan, still can not effectively solve oil fume pumping-clean rate.
4. the oil smoke impeller of flowing through, very easily precipitation accumulates tobacco tar on blade and walling of flue, cleans very difficult.
The utility model provides a kind of spiral-flow type smoke exhaust ventilator that utilizes swirling eddy pump drainage oil smoke for the deficiency that solves above-mentioned smoke exhaust ventilator existence designs.
The utility model is to be made of air intake tube, blower fan, cyclone, whirl cylinder, air inlet air duct, gas collection air duct, exhaust duct, casing.Blower fan is rack-mount, and the air intake tube is connected with the air inlet of blower fan, and the air outlet of blower fan links to each other with the air inlet of cyclone, and whirl cylinder is installed in the air outlet of cyclone.The air inlet air duct places the centre of cyclone.Air inlet air duct bottom is the gas collection air duct, is horn-like.The upper port of air inlet air duct and pass cyclone and place cyclone and whirl cylinder in, cyclone and whirl cylinder constitute the eddy flow generating means, its effect is to produce swirling eddy, swirling eddy produces the low pressure core, be negative pressuren zone, the upper port of air inlet air duct is positioned at eddy flow generating means inside and is in the low pressure core space.The lower port of the gas collection air duct of air inlet air duct bottom places the bottom surface outside of casing, and the lower end of exhaust duct is connected with the upper end of whirl cylinder, and exhaust duct is a gradually expanded form, as shown in Figure 1 and Figure 2.Cyclone and whirl cylinder are the eddy flow generating means, and main effect is to produce swirling eddy, and the vortex intensity of swirling eddy is strong more, the pressure of core space is just low more, the pressure reduction that the air inlet air duct is imported and exported two ends is just big more, and the suction capactity of generation is just strong more, and the pumping-clean rate of oil smoke is just high more.
During use, cleaned air enters blower fan through the air intake tube, blower fan blows into cyclone with cleaned air, cleaned air rotates in cyclone, forms swirling eddy, and rises along the eddy flow rotation, upper port at the air inlet air duct forms the low pressure core, produce powerful suction capactity, the oil smoke around the gas collection air duct lower port of air inlet air duct is drawn in the exhaust duct, along with swirling eddy is discharged outdoor along exhaust duct.
Oil smoke passage of the present utility model only is a hollow garden tube, and air-flow is unobstructed.Not only improved the pumping-clean rate of oil smoke, and tobacco tar is difficult for precipitation and accumulates,, clean also very convenient even if a little long-pending oil is arranged.And what flow through blower fan and swirl-flow devices is cleaned air, so blower fan and cyclone need not often clean.
The gas collection air duct can be changed shape and size according to the needs that use, can under different duties, use.Can be the gas collection air duct of air inlet air duct along the bottom surface outside that casing extends to casing up to the optimum position of collecting oil smoke, gas collection air duct lower port can be the opening port shape, as shown in Figure 3.
Gas collection air duct of the present utility model can sink to the optimum position of collecting oil smoke along the casing inboard, and does not hinder and manipulate, and can more effectively avoid the air-flow short circuit, and oil smoke is excessive.As shown in Figure 3.
The utility model has been abandoned fully and has been utilized directly the dry mode of pump drainage oil smoke of blower fan, utilizes swirling eddy to make low pressure (negative pressure) core and produces the effect that powerful suction capactity reaches the pump drainage oil smoke.The suction capactity of this low pressure core is powerful more a lot of than the suction capactity of the direct blowing of blower fan.
The oil smoke draught fan impeller of not flowing through in the utility model, thus many disadvantages of prior art thoroughly eradicated.Has the oil fume pumping-clean rate height; The oil smoke draught fan impeller of not flowing through makes the stable performance of blower fan, reduces noise; It is convenient to clean; Energy saving is more than 40%.
The utlity model has the oil fume pumping-clean rate height, fan performance is stable, and noise is low, and it is convenient to clean, and advantages such as energy saving are mainly used in family, also applicable to the pump drainage oil smoke in commercial food and drink kitchen and be used for the place of other air-flow of pump drainage (suction).Not only can be used for kitchen pump drainage oil smoke, also can be used for other different gas of pump drainage (suction), purposes is very extensive.
