Abstract
A kind of range hood, comprise housing, be positioned at the air inlet on housing and air outlet, the main inlet channel being communicated with described air inlet and air outlet is formed in described housing, spiral case is provided with in described main inlet channel, described air inlet is located at the centre position of the exhaust fume collecting hood of housing, it is characterized in that: the periphery of described exhaust fume collecting hood is provided with auxilairy air intake, described auxilairy air intake is communicated to the auxiliary air inlet channel being positioned at housing, described auxiliary air inlet channel is communicated to described spiral case, and described auxiliary air inlet channel and the main inlet channel between spiral case and air inlet separate.This range hood, not only structure is simple, arranges conveniently, directly arranges in the peripheral part of exhaust fume collecting hood the auxilairy air intake being communicated to spiral case, oil smoke can be made to suck more thorough, reduce the escape of oil smoke.
Description
Technical field
The utility model relates to a kind of range hood.
Background technology
Existing range hood, no matter be straight suction or side draught, mostly be arranged at the top of the kitchen range top, exhaust fume collecting hood is towards the kitchen range top, at the approximate centre position of exhaust fume collecting hood, air inlet fume-exhausting is set, assembling lampblack absorber inner between exhaust opening and air inlet to form inlet channel, the set-up mode of this lampblack absorber, air inlet is only formed in very little scope, therefore in order to obtain larger fume-exhausting efficiency, all need to configure powerful blower fan to improve suction, but oil smoke air inlet is only formed in the position at exhaust fume collecting hood center, its suction can be decayed rapidly to external radiation, make exhaust fume collecting hood edge suction very faint.And the oil smoke risen that upwards wafts of being heated can be rapidly to surrounding diffusion, an oil smoke air mass for diffusion of wafing liter can depart from centre, and the oil smoke at exhaust fume collecting hood edge is easily escaped.Therefore some producer adopts the mode strengthening, deepen exhaust fume collecting hood to solve the problem of fumes escaping, so not only increase volume and also add cost, some also arranges air curtain and attempts to stop fumes escaping at exhaust fume collecting hood edge, but due to air curtain to blowing down oil smoke upwards both mutually drive in the wrong direction, the effect of prevention fumes escaping neither be ideal, and air curtain is set needs to arrange blower fan in addition, also increase energy consumption and improve cost.
Utility model content
Technical problem to be solved in the utility model is to provide one effectively can prevent fumes escaping, improves the range hood of smoke absorption effect.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of range hood, comprise housing, be positioned at the air inlet on housing and air outlet, the main inlet channel being communicated with described air inlet and air outlet is formed in described housing, spiral case is provided with in described main inlet channel, described air inlet is located at the centre position of the exhaust fume collecting hood of housing, it is characterized in that: the periphery of described exhaust fume collecting hood is provided with auxilairy air intake, described auxilairy air intake is communicated to the auxiliary air inlet channel being positioned at housing, described auxiliary air inlet channel is communicated to described spiral case, and described auxiliary air inlet channel and the main inlet channel between spiral case and air inlet separate.
Preferably, two side positions of exhaust fume collecting hood are located at by described auxilairy air intake.
Compared with prior art, the utility model has the advantage of this range hood, structure is simple, arranges conveniently, directly arranges in the peripheral part of exhaust fume collecting hood the auxilairy air intake being communicated to spiral case, oil smoke can be made to suck more thorough, reduce the escape of oil smoke.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the range hood of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, for the schematic diagram of the range hood of the utility model embodiment, this range hood comprises housing 1, and the air inlet 11 be positioned on housing 1 and air outlet 12, the main inlet channel 2 being communicated with air inlet 11 and air outlet 12 is formed in described housing 1, be provided with spiral case 3 in this main inlet channel 2, in spiral case 3, be provided with the parts that fan, motor etc. play air draught effect.
The air inlet 11 of this range hood is located at housing 1 towards the centre position on the exhaust fume collecting hood 13 of the kitchen range top, cowling panel 8 and filter screen 9 is provided with at air inlet 11 place, at the periphery of described exhaust fume collecting hood 13, be provided with auxilairy air intake 4, this auxilairy air intake 4 is communicated to the auxiliary air inlet channel 5 being positioned at housing 1, this auxiliary air inlet channel 5 is communicated to spiral case 3, and and the separate isolation of main inlet channel 2 between spiral case 3 and air inlet 11, arrow is as shown in Figure 1 depicted as the air-flow entering auxiliary air inlet channel 5 from auxilairy air intake 4.This auxilairy air intake 4 can be arranged along the surrounding of exhaust fume collecting hood 13, such as, in the front, rear, left and right of exhaust fume collecting hood, every side is equipped with auxilairy air intake 4, auxilairy air intake 4 can be overall one, also can be that multiple little air inlet forms one group of air inlet and is arranged on exhaust fume collecting hood 13.
Preferably, the auxilairy air intake 4 on this exhaust fume collecting hood 13 is only formed on two side positions of the periphery of exhaust fume collecting hood 13, and the auxiliary air inlet channel 5 that each auxilairy air intake 4 connects is interconnected, also can be separate.Auxilairy air intake 4 on this exhaust fume collecting hood 13 also can arrange a circle around the periphery of exhaust fume collecting hood 13.
Due to the peripheral part of exhaust fume collecting hood 13, the general escape causing oil smoke because negative pressure is not enough, therefore, auxilairy air intake 4 is set at the periphery of exhaust fume collecting hood 13 and is directly communicated to spiral case 3, make the peripheral part of exhaust fume collecting hood 13 can obtain larger negative pressure, and then the larger suction of generation can suck oil smoke, thus reduce the escape of oil smoke.
This range hood, not only structure is simple, arranges conveniently, directly arranges in the peripheral part of exhaust fume collecting hood the auxilairy air intake being communicated to spiral case, oil smoke can be made to suck more thorough, reduce the escape of oil smoke.
Although more than describe in detail preferred embodiment of the present utility model, should be expressly understood that, for a person skilled in the art, the utility model can have various modifications and variations.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
