Abstract
The utility model relates to a kitchen ventilator, particularly a kitchen ventilator with an air curtain apparatus. The kitchen ventilator comprises a fume collecting hood, wherein the air curtain apparatus is arranged in the fume collecting hood. The air curtain apparatus is composed of an outer shell, a cross-flow fan, an air inlet and air outlets. The air outlets are arranged below the fume collecting hood, are composed of air boards and are split into an inner air outlet and an outer air outlet. The inner air outlet faces to the inner side of the fume collecting hood to form an inner layer air curtain, and the outer air outlet faces to the outer side of the fume collecting hood to form an outer layer air curtain. The utility model uses the cross-flow fan in the air curtain apparatus to generate air force which output air via the two air outlets, so two air curtains are formed. The inner layer air curtain can effectively prevent fume from diffusing in the rising process. The outer layer air curtain prevents the fume from diffusing further, and can also give fresh air to operators.
Description
Technical field
The utility model relates to a kind of range hood, relates in particular to a kind of range hood that has air curtain apparatus.
Background technology
Lampblack absorber in the market, no matter be that formula is washed on dark type side-suction type, half dark type top, general installation requirement is on the kitchen range between about 650mm～750mm, this oil smoke that still has a considerable part apart from oil smoke in the process that rises is diffused into the space outside the exhaust fume collecting hood, in fact the real effectively smoking of lampblack absorber highly should be 300mm～400mm, can be reduced to this height to lampblack absorber, people at all can't be at the enterprising line operate of kitchen range.Also have a lampblack absorber that has air curtain apparatus, it is provided with air curtain apparatus in the exhaust fume collecting hood of lampblack absorber, and the diffusion the when air curtain that forms by air curtain apparatus stops that oil smoke rises improves oil suction cigarette effect.But this lampblack absorber can only form one deck air curtain, still have the not exhaustion of part oil smoke during use.
Summary of the invention
At the not high shortcoming of lampblack absorber clean absorption rate in the background technology, the utility model provides a kind of oil smoke clean absorption rate high range hood.
The utility model range hood technical scheme be: a kind of range hood, comprise exhaust fume collecting hood, be provided with the air curtain device in exhaust fume collecting hood, this air curtain device is made up of shell, cross flow fan, air inlet and air outlet, and air outlet is arranged on the exhaust fume collecting hood below, air outlet is made of wind deflector, air outlet and outer air outlet in air outlet is divided into, interior air outlet form the internal layer air curtain towards the exhaust fume collecting hood inboard, outer air outlet forms outer air curtain towards the exhaust fume collecting hood outside.
Described air outlet constitutes the long and narrow shape of twitching one's mouth by wind deflector.
The air curtain device can be arranged on the side of close operator in the lampblack absorber exhaust fume collecting hood.
Also can be respectively equipped with the air curtain device in the both sides of lampblack absorber exhaust fume collecting hood.
The utility model range hood is provided with the air curtain device in exhaust fume collecting hood, the wind-force that utilizes the cross flow fan in the air curtain device to produce, by 2 air outlet air-out, form 2 road air curtains, the internal layer air curtain can effectively stop the diffusion of oil smoke in uphill process, outer air curtain can also bring ozone to the operator except further stopping the oil smoke diffusion.

Fig. 2: the structural representation of Fig. 1 apoplexy curtain device 3.
The specific embodiment
Below in conjunction with Fig. 1, Fig. 2 an embodiment of the present utility model is elaborated.The present embodiment range hood comprises exhaust fume collecting hood 1, in exhaust fume collecting hood, be provided with air curtain device 3, this air curtain device 3 is made up of shell 9, cross flow fan 8, air inlet 7 and air outlet, air inlet 7 directly exposes above exhaust fume collecting hood 1, air outlet is arranged on the side of exhaust fume collecting hood 1 below near the operator, air outlet constitutes the long and narrow shape of twitching one's mouth by wind deflector 10, air outlet 12 and outer air outlet 11 in air outlet is divided into, interior air outlet 12 is towards the exhaust fume collecting hood inboard, form internal layer air curtain 5, outer air outlet 11 forms outer air curtain 4 towards the exhaust fume collecting hood outside.
Above-mentioned range hood can also respectively be provided with the air curtain device in the both sides of exhaust fume collecting hood, makes the more thorough of oil smoke absorption.
When above-mentioned lampblack absorber is worked, open cross flow fan 8, fresh air 2 is through air inlet 7, form internal layer air curtain 5 and outer air curtain 4 by interior air outlet 12 and outer air outlet 11, when oil smoke rises, because the suction deficiency of range hood, some oil smoke 6 spread in uphill process, when it spreads, force oil smoke 6 to enter range hood, and outer air curtain also can make the oil smoke of a small amount of escape enter lampblack absorber, returns the operator and brings ozone owing under the effect of internal layer air curtain.
Claims (4)
