Abstract
The utility model relates to a dual-purpose oil fume extracting-exhausting machine, comprising an outer shell (7) and a blower fan (4) used for extracting oil fume. The utility model is characterized in that the back part of an oil fume extracting passage (11) is communicated with an air inlet passage of an oil separator (10); the air inlet passage of the oil separator (10) extends downwards to be communicated with an inlet of the oil separator (1) at the lower part; an outlet at the upper part of the oil separator (1) is connected with an air outlet passage of the oil separator (3); the air outlet passage of the oil separator (3) is communicated with an inlet of the blower fan (4) through an oil filtering plate (2). The utility model can use the oil separator to collect oil fume particles, and the oil fume particles are processed by a first air cleaning filter and a second air cleaning filter to be exhausted indoors as clean air flows. Or the oil fume particles are processed by the first air cleaning filter, an air exhaust guide pipe is matched and connected, and the oil fume particles are exhausted outdoors as pollution-free air. The utility model can be used as not only a circulating type but also an external exhausting type.
Description
The utility model relates to the kitchen hood in a kind of kitchen.
Present kitchen hood comprises shell and blower fan, and the most of mist of oil that is sucked is discharged to outdoor with flue gas, forms environmental pollution.And easily causing draught fan impeller and passage to stop up, the user need regularly unpick and wash.The family expenses kitchen hood that has has installed oil cleaner screen additional in blower fan import department, though this has removed some mist of oils, oil cleaner screen very easily stops up, and resistance increases, and need often unpick and wash.
The purpose of this utility model is to provide a kind of oil smoke gas that purifies suction, is emitted on indoor or is discharged to outdoor dual-purpose type kitchen hood by exhaust manifolds.
The technical solution of the utility model is: it comprises shell [7], blower fan [4], Open Side Down for oil smoke suction passage [11], it is characterized in that: described oil smoke suction passage [11] is gone into gas passage [10] with oil eliminator and is connected, oil eliminator is gone into gas passage [10] and is communicated with oil eliminator [1] inlet of below the extension back downwards, described oil eliminator is gone into the sectional area of the sectional area of gas passage [10] less than oil smoke suction passage [11], described oil eliminator [1] is the cavity of a band oil strain plate [2], the outlet on oil eliminator [1] top connects oil eliminator outlet passageway [3], the sectional area of oil eliminator outlet passageway [3] is gone into the sectional area of gas passage [10] greater than oil eliminator, described oil eliminator outlet passageway [3] is connected to the inlet of blower fan [4], the air-out passage of described blower fan [4] is provided with I level air cleaning filter [6] and II level air cleaning filter [9] and exhaust manifolds [8], described I level air cleaning filter [6] is provided with sorbing material, and described II level air cleaning filter [9] is provided with filtering material.In the cavity of described oil eliminator [1] water is housed.Described oil strain plate [2] is the metallic plate that is provided with a plurality of micropores.
Oil eliminator of the present utility model is used and is impacted the demist principle, during work, flue gas anxious turnback behind the oil smoke suction passage is gone into the gas passage along oil eliminator and is quickened to enter oil eliminator downwards, anxious again turnback also upwards enters blower fan along the oil eliminator outlet passageway through the oil strain plate with the speed that slows down greatly, in this process, mist of oil drips owing to effect of inertia rushes at the oil eliminator water surface and is caught to cut in the flue gas.
The utility model compared with prior art has following advantage:
(1), can store in a large number isolated oil from oil smoke and do not need usually to unpick and wash, so easy to use because the cavity of oil eliminator has bigger volume.
(2) oil smoke through purifying, so the blade of blower fan can keep clean, influences the rotation of blower fan lessly before entering blower fan, does not need to clean simultaneously blower fan.
(3) suck the air be subjected to fume pollution, after blower fan outlet I level purifies, connect exhaust manifolds and be discharged to outdoorly, environment is not constituted pollution.
(4) suck the air that is subjected to fume pollution, after blower fan outlet II level purifies, be emitted on indoor for purifying air.Made things convenient for the special user.
The utility model will be further described below in conjunction with drawings and Examples.
Accompanying drawing is structure master's cutaway view of the present utility model, wherein:
[1] oil eliminator; [2] oil strain plate; [3] oil eliminator outlet passageway; [4] blower fan; [5] volute; [6] I level air cleaning filter; [7] shell; [8] exhaust manifolds connect mouth; [9] II level air cleaning filter; [10] oil eliminator is gone into the gas passage; [11] oil smoke suction passage.
Embodiment: referring to accompanying drawing, the utility model comprises shell [7], be used to suck the blower fan [4] of flue gas, Open Side Down for oil smoke suction passage [11], described oil smoke suction passage [11] is gone into gas passage [10] with the oil eliminator of vertical direction and is connected on top, oil eliminator is gone into gas passage [10] and is communicated with oil eliminator [1] inlet of below the extension back downwards, the sectional area that described oil eliminator is gone into gas passage [10] is far smaller than the sectional area of oil smoke suction passage [11], its sectional area differs ten times in the present embodiment, purpose is to make oil smoke after the bigger oil smoke suction passage [11] of sectional area enters the less oil eliminator of sectional area and goes into gas passage [10], and the speed of air-flow can increase greatly.Described oil eliminator [1] is the cavity of a band oil strain plate, and clear water is housed in the cavity, and the oily particulate that impacts downwards can be caught by the water surface at a high speed.Oil strain plate [2] is held back the tobacco tar after oil eliminator separates for be drawn into the metallic plate of a plurality of micropores through spurt, and the described oil droplet that is trapped flows into the water surface of oil eliminator [1] equally.The outlet on oil eliminator [1] top connects oil eliminator outlet passageway [3], and the sectional area of oil eliminator outlet passageway [3] is far longer than the sectional area that oil eliminator is gone into gas passage [10], and its sectional area differs three times here.Described oil eliminator outlet passageway [3] is switched to the inlet of blower fan [4] through oil strain plate [2].Blower fan [4] is provided with one, is centrifugal blower; The air-out passage of described blower fan [4] is provided with I level air cleaning filter [6].Described I level air cleaning filter [6] is to form by the filtering material of the sorbing material of thickness 4-10mm and thickness 2-3mm is folding.Described I level air cleaning filter can be removed harmful and noxious substances such as butadiene, aldehydes.For the air-flow that blower fan [4] is blown out is distributed on the I level air cleaning filter [6] equably, also be convenient to the accurately fixing of blower fan, be provided with volute [5].The air-out passage of described blower fan [4] is emitted on cleaned air passes indoor by II level air cleaning filter [9], or is discharged to outdoor by exhaust manifolds [8] cleaned air passes.So the utility model can burrow on the wall, take over, and is easy to install.Pollution-free again to airborne release, keep the neat and artistic of exterior wall.
