Abstract
The utility model relates to a cooking fume separation exhauster with an air curtain. On the basis of the prior art, the utility model is additionally provided with an air curtain fan and a wind guide shaft, wherein, the air curtain fan is arranged on a fume hood; the wind guide shaft which is provided with a wind outlet is connected with the air curtain fan. Thus the utility model has the advantages of reasonable structural design, unique idea, good cooking fume exhausting effect, low noise at the time of use, etc.
Description
The utility model relates to a kind of range hood, particularly a kind of range hood with air curtain, and it mainly is suitable for family and uses.
Family expenses range hood of the prior art mainly is made up of petticoat pipe, axial flow blower and outlet flue, and axial flow blower is installed in the petticoat pipe; During use, oil smoke is discharged from outlet flue by axial flow blower.But this structure take off the oil extraction machine in actual use ubiquity that mist extractor is clean, big these two the fatal shortcomings of noise.Though a lot of improvement have also been done by each producer for this reason, attempt to improve the performance of smoke exhaust as adopting the method that strengthens axial flow blower power, uses dark type petticoat pipe, the result all can not make the user satisfied.Reason is the restriction that is subjected to aerodynamic principle, when power of fan is increased to a certain degree, be subjected to the restriction of flue sectional area, exhausting efficient will sharply descend, and the noise that flow-disturbing produces sharply strengthens, dark type petticoat pipe is subjected to the restriction of service condition, can not install lowly, can't solve the resonant tank that the air-flow short circuit problem but becomes noise on the contrary; This just makes existing various smoke exhausts be difficult to have the raising of matter again.
The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and the range hood of the band air curtain of a kind of reasonable in design, design uniqueness is provided, and improves the mist extractor effect to reach, and reduces the purpose of smoke exhaust noise.
The purpose that the utility model proposed can be achieved through the following technical solutions: this range hood comprises petticoat pipe, axial flow blower and outlet flue, its design feature is also to be provided with Windscreen Fan and wind-guiding axle, Windscreen Fan can be installed on the petticoat pipe, the wind-guiding axle then can link to each other with Windscreen Fan, and has the air port on this wind-guiding axle.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design has higher oil fume pumping-clean rate; 2, owing to only needing less axial flow blower power can obtain mist extractor effect preferably, so greatly reduce the noise of smoke exhaust; 3, can be according to using needs that the height of range hood more optionally is installed, the scope of application is wider.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a kind of structural representation of Windscreen Fan of the present utility model and wind-guiding axle.
Fig. 3 is user mode figure of the present utility model.
Referring to Fig. 1, Fig. 2, the utility model mainly is made up of petticoat pipe 1, axial flow blower 2, Windscreen Fan 3 and wind-guiding axle 4, axial flow blower 2 is installed in the petticoat pipe 1, Windscreen Fan 3 is installed on the petticoat pipe 1, this Windscreen Fan 3 is installed one or more at least, and its power and exit angle can be designed to adjustable, to satisfy the demand of various environments for use; Wind-guiding axle 4 can link to each other with Windscreen Fan 3, and as can being plugged on the Windscreen Fan 3, wind-guiding axle 4 directly links to each other or links to each other indirectly with comprising linking to each other of Windscreen Fan 3, or coupled by air channel 7; And on this wind-guiding axle 4, have air outlet 4-1, the wind that blows out from this air outlet 4-1 has just formed invisible air curtain 5 (see figure 3)s, it has prolonged the lower edge of petticoat pipe 1, formed tight invisible petticoat pipe, blocked the inside and outside air short circuit phenomenon of invisible air curtain 5, make the oil smoke in the air curtain 5 to leak, air curtain 5 outer air also can't enter in the air curtain 5 in short circuit; For being suitable for various user demand, wind-guiding axle 4 is designed to rotatable, suitably to change the size of air curtain 5.Therefore, only need the axial flow blower 2 of smaller power can obtain good mist extractor effect; Simultaneously, can adopt shallow type petticoat pipe 1 to reach the purpose that reduces the smoke exhaust noise fully.
Most preferred embodiment of the present utility model is that the outer is equipped with Windscreen Fan 3 around petticoat pipe 1.Certainly, Windscreen Fan 3 is installed on other position of petticoat pipe 1 and also is fine, and is flue as long as can form invisible air curtain 5,6.
