Description
Technical field
The utility model relates to a kind of culinary range hood, a kind of air curtain range hood of more specifically saying so.
Background technology
Traditional range hood for kitchen use, comprise a body, exhaust blower by power switch control is housed on the body, the oil smoke and the steam that produce when this exhaust blower is cooked cooking are discharged to outdoor through exhaust duct, its weak point is: 1, summer with air conditioner refrigerating or in winter during with heating equipment heating, indoorly often door and window is closed, when cooking, cooking opens range hood, indoor meeting produces negative pressure, under the effect of this negative pressure, the air that has dust on the one hand in the environment can be from the slit of door and window in the inlet chamber, refrigeration or heating effect had both been influenced, the room of making dirty again is by the floor drain in the drainage system of kitchen and toilet on the other hand, with peculiar smell or stink return scurry indoor; The oil smoke that is produced when 2, cooking is cooked, it is outdoor to be that a part is discharged to, and some loss drops on kitchen tools, furniture and the wall indoor, forms greasy thing.2 above-mentioned deficiencies cause traditional range hood when cooking is cooked, and are both unhygienic, pollute room air again.
Summary of the invention
The purpose of this utility model provides a kind of not only health, room air but also fresh air curtain range hood.
In order to realize above-mentioned purpose, the air curtain range hood that is provided, comprise body, be provided with overhanging exhausting duct in the body, the lower ending opening of this exhausting duct is in the bottom surface of body, upper port can socket be stretched to outdoor exhaust duct, exhaust blower is housed in the exhausting duct, its design feature is that the end face of body is provided with and is communicated with the inner chamber of body and overhanging air inlet duct, the upper port of air inlet duct can socket be stretched to outdoor blast pipe, new blower fan is housed in the air inlet duct, four sides of body bottom surface are provided with the exhaust vent that is communicated with the body inner chamber, and the new wind of discharging through exhaust vent forms the air curtain that stops the oil smoke loss.
In order to purify in the inlet chamber and to form the air of air curtain, filter also is housed in the above-mentioned air inlet duct, filter is arranged on the place ahead of new blower fan.
In order not make indoor generation negative pressure, the exhaust air rate of new blower fan is greater than or equals the exhaust air rate of exhaust blower.
For simplified structure, above-mentioned exhaust blower and new blower fan unification are controlled switching on and off of its power supply simultaneously by the power switch that is contained on the body surface.
The operation principle of air curtain range hood provided by the utility model is: when cooking is cooked, connect the power supply of new blower fan and exhaust blower by power switch, new blower fan and exhaust blower work, under the effect of new blower fan, outdoor fresh air enters the body inner chamber after being filtered through filter by air inlet duct, discharge downwards by the exhaust vent that is arranged on four sides in body bottom surface then, above the cooking stove periphery, form air curtain, this air curtain is cooked the oil smoke that produced and vapor barrier above cooking stove with cooking, by exhaust blower through exhausting duct, exhaust duct is discharged to outdoor, prevents that loss is indoor, the room of making dirty.Owing to send into indoor new blower fan filters outdoor fresh air through filter after, and the exhaust air rate of new blower fan is more than or equal to the exhaust air rate of exhaust blower, therefore indoorly can not produce negative pressure, on the one hand be avoided having in the environment dust air from the slit of door and window in the inlet chamber, the room of making dirty, be to have avoided peculiar smell or stink being returned scurrying indoorly on the other hand, make room air fresh by the floor drain in the drainage system of kitchen, toilet.
Learn that by top narration air curtain range hood provided by the utility model can make indoor health and air fresh.
