Description
Technical field
The utility model relates to a kind of range hood field, especially relates to a kind of kitchen small-sized cyclone fume-exhausting system and rotates air curtain generator.
Background technology
Range hood is the Main Means of the indoor oil smoke trapping in kitchen, and the pumping efficiency how improving range hood is the important content of range hood design and researchp always.The fume-exhausting process of traditional range hood can regard the suction of point sink formula as, as shown in Figure 5, the rule of point sink formula suction is that flow is equal on each constant speed sphere of meeting point different distance, along with the increase leaving meeting point distance, flow velocity is quadratic power decay, so the energy attenuation of inspiratory airflow is very fast, cause range hood can the air draught region of actual influence very little.If therefore application technology means oil smoke can be limited in certain area, realize there is important impact on the control and suck of oil smoke by the performance of range hood.
At present, the existing various range hood that can form artificial spout below range hood in the prior art, if the patent No. is " a kind of rotary wind screen range hood with lampblack filter " disclosed in the Chinese invention patent of ZL201210396787.9 (Authorization Notice No. is CN102913970B), the principle that this range hood produces whirlwind is: stretch out four pipelines at four side-lowers of lampblack absorber, pipeline has crack, by blower fan, whirlwind is sent formation from crack again and horizontally rotate air curtain, thus whirlwind is formed under the swabbing action of lampblack absorber, the major defect of this range hood is: rotary wind screen shielding surface is larger, energy is concentrated not, the whirlwind intensity of crack blowout is more weak, antijamming capability is poor, and, the apparatus structure producing rotary wind screen is also compact not.And for example the patent No. is " a kind of Tornado type range hood " disclosed in the Chinese invention patent application of ZL201310590169.2 (application publication number is CN103673009A), the principle of the fume-exhausting of this range hood is the mode adopting drainage, two blower fans in outside are after the passage of design, although the air-flow rotated upwards can be formed in air inlet outer, thus drive flue gas to be sucked away, but siphon away because flue gas to be driven by the air-flow that rotates, therefore it only has faint eddy flow effect in air inlet, thus the height forming cyclone can not be very high, and then the smoke absorption effect of range hood can not be significantly improved.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, rotation air curtain generator 2 in the present embodiment comprises six breeze fans 21 and six pieces of deflectors 22, breeze fan 21 is uniformly distributed along the circumferencial direction interval of pot 3, breeze fan 21 and deflector 22 are arranged on above the platen of the kitchen range top 4, and, in order to not affect user's operation, breeze fan 21 and deflector 22 be not higher than pot edge.Breeze fan 21 forms air-supply arrangement, the air outlet 211 of breeze fan 21 is the air outlet of air-supply arrangement, deflector 22 is with breeze fan 21 one_to_one corresponding and be arranged on air outlet 211 place of corresponding breeze fan 21, the edge-on setting of deflector 22 and curving inwardly, and the air outlet 211 of breeze fan 21 is towards the inner concave of deflector 22.
In order to form better cyclone effect, the structure also following condition of demand fulfillment of breeze fan 21 and deflector 22: the radius of curvature of deflector 22 is not less than 80mm, the air outlet 211 of breeze fan 21 is horizontally disposed with or arranges obliquely, and the angle of air outlet 211 plane and horizontal plane is 10 ~ 90 °.In addition the cold air blast velocity of breeze fan 21 is 1 ~ 10m/s; The flow of the air outlet of breeze fan 21 is 0 ~ 4m
3/ min.
As shown in Figure 3, rotating air curtain generator is arranged on above the platen of the kitchen range top 4, rotate air curtain generator 2 to be provided separately with range hood 1, rotate air curtain generator 2 to be positioned at immediately below range hood 1 and to be arranged on and be placed on pot 3 on the kitchen range top 4 around, namely breeze fan 21 and deflector 22 are trapped among the surrounding of pot 3.Rotate air curtain generator to coordinate with range hood and form kitchen small-sized cyclone fume-exhausting system, during work, the flue gas to be pumped risen is produced in pot 3, rotate air curtain generator 2 to generate and rotate upwards and the rotation air curtain of flue gas to be pumped of shielding, flue gas to be pumped forms cyclone shape movement locus under the acting in conjunction of described rotation air curtain and cooking-fume exhauster blower system.
As shown in Figure 4, rotating air curtain generator is arranged on below the platen of the kitchen range top 4, particularly, the breeze fan 21 and the deflector 22 that rotate air curtain generator 2 are arranged on below the platen of the kitchen range top 4, platen has and the air outlet 211 of breeze fan air vent 41 one to one, air vent 41 is trapped among the surrounding of pot 3, and the air outlet 211 frontage and airiness hole 41 of breeze fan 21.
The physical condition formed based on cyclone is known, on the one hand, utilizes the swabbing action of range hood 1 to form the air-flow risen; On the other hand, the method adopting the inclination supply air system of breeze fan 21 to add deflector 22 produces the swirling eddy rotated upwards, its airflow direction that can be analyzed to airflow direction upwards and horizontally rotate, air-flow upwards is more easily caught by range hood, thus form the air curtain (on the path that oil smoke rises) closed, the air-flow horizontally rotated utilizes air viscosity effect to generate the shearing force of horizontal direction, make inlet flow field generate enough tangential rotary speeies, and then generate spout eddy flow velocity profile.
During work, open the breeze fan 21 of range hood 1 and rotation air curtain generator 2 simultaneously, the rotation air curtain rotating air curtain generator 2 formation can shield isolation oil smoke generation area, form the air curtain closed, stop oil smoke to spread diffusion, in addition, its spout eddy flow velocity profile formed has comparatively strong suction, the upwards directed flow of oil smoke can be ensured, shorten the operating path of oil smoke, oil smoke be gathered and quick drain.Find through test, this cyclone forming apparatus can realize effective control of oil smoke, and negative pressuren zone is increased, and air draught ability is strengthened greatly, and the power rotating air curtain generator is very low, and noise is less.
