Abstract
The utility model discloses a range hood capable of preventing oil fume from leaking indoors. The range hood comprises an air collection cover and a box, wherein the box is internally provided with an air suction system and an air supplying system, and the air suction system is isolated from the air supplying system; the air suction system is provided with a first wind wheel and a first motor for driving the first wind wheel; the air supplying system is provided with a second wind wheel and a second motor for driving the second wind wheel, and the rotating direction of the first wind wheel is reverse to that of the second wind wheel; the air collection cover forms an air collection region in a surrounding manner, the air collection region is connected with the air suction system, the air collection cover comprises an interlayer, and the interlayer is connected with the air supplying system and is provided with an opening in the edge of the air collection cover. Since oil fume is blocked by an air curtain formed by air rather than an entity, the space occupied by the air collection cover can be reduced under the condition of guaranteeing good oil fume suction and discharging effects, and sequentially, the influence on users is alleviated.
Description
Technical field
The present invention relates to a kind of smoke-discharging device in kichen, be specifically related to a kind of smoke exhaust ventilator.
Background technology
The smoke exhaust ventilator that occurs in the market, have slim, inferior dark type, dark cabinet type etc. by the wind-collecting cover classification.Wherein slim do not have a wind-collecting cover, and the wind cabinet is shallow, and the smoke suction effect is poor, and oil smoke is loose overflowing to indoor easily; Dark cabinet type has large darker wind cabinet and wind-collecting cover, can cover the oil smoke in rising, and the smoke suction effect is better, but owing to being installed on the cooking stove top, wind cabinet and wind-collecting cover are larger again, take up room large, affect very much user's activity, and make consumptive material and also increase, save not; And inferior dark type is in slim with deeply between the cabinet type, and adverse effect is less, but result of use is also than both decreasing.
Therefore, be badly in need of a kind of novel smoke exhaust ventilator to address the above problem.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can reduce user's impact and can prevent that oil smoke is emitted to indoor smoke exhaust ventilator.
, in order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of smoke exhaust ventilator, comprise wind-collecting cover, casing, is provided with the described air draft system of air draft system and supply air system and the isolation of described supply air system in described casing; Described air draft system is equiped with one first wind wheel and drives one first motor of described the first wind wheel; Described supply air system is equiped with one second wind wheel and drives one second motor of described the second wind wheel, the switched in opposite of described the first wind wheel and described the second wind wheel; Described wind-collecting cover surrounds a collection wind joint area described air draft system, and described wind-collecting cover has interlayer, and described interlayer connects described supply air system, and described interlayer is provided with opening and is positioned at described wind-collecting cover edge; During work, the wind that is entered described interlayer by described supply air system forms the air curtain that stops oil smoke dissipation after described opening high-speed penetrates, and described air draft system sucks oil smoke simultaneously.
Described air draft system has one first bellows, and described the first bellows have one first entrance and one first outlet that is oppositely arranged, and described the first motor and described the first wind wheel are installed in described the first bellows and near described first and export; Described supply air system has one second bellows, and described the second bellows have one second entrance and one second outlet that is oppositely arranged, and described the second motor and described the second wind wheel are installed in described the second bellows and near described second and export.
Described the first entrance and described the first outlet are positioned at described casing the same side.
Described the first motor is identical with described the second rating of machine, both synchronously drives.
Described the first wind wheel is identical with the specification of described the second wind wheel.
Beneficial effect of the present invention is: the air of being sent into by described supply air system, after described interlayer restriction, penetrates and forms air curtain from described opening high-speed, oil smoke can be blocked in the space that air curtain surrounds, and prevents that oil smoke from dissipating to indoor; The air curtain that forms of air but not entity due to what stop oil smoke, thus can be in the situation that guarantee that good fume exhaust effect dwindles wind-collecting cover and take up room, thus reduce the impact on the user.
