Abstract
A range hood for oil fume decontamination of household kitchens belongs to the field of household appliances, and solves the problem that flue gas in a kitchen pollutes the environment. A flue gas decontamination chamber is arranged behind a casing of the range hood; an inclined flue gas division board is arranged at the middle part; a decontamination liquid nozzle is arranged above the flue gas division board; an air inlet of a blower is arranged under the flue gas division board; a water curtain nozzle is arranged at the end part of the lower end of the flue gas division board; a decontamination flume is arranged at the lower part of the flue gas decontamination chamber; a circulating water pump is connected with the decontamination flume; a water outlet is connected with the decontamination liquid nozzle and the water curtain nozzle; the water curtain is arranged on a flue gas passage of the range hood, and water for forming the water curtain is decontamination liquid added with oil dissolving agents. When flue gas passes through the water curtain under the suction force of the range hood, oil mist in the flue gas is completely contacted with the decontamination liquid, so that all the oil mist is dissolved in the decontamination liquid, and the decontaminated flue gas is discharged outdoors through the blower. The range hood has the characteristics of simple structure, practicability, convenience, high purification efficiency, energy conservation and environmental protection, and is suitable for decontamination and exhaust of flue gas in household kitchens.
Description
Technical field
The utility model belongs to household appliance technical field, mainly relates to the range hood of the family kitchen fume purifying that can purify and discharge the oil smoke that family kitchen produces.
Background technology
The range hood that family uses is that the oil smoke gas that has that family kitchen produces is discharged into outdoor a kind of household electrical appliance, mainly be attraction by blower fan with oil smoke discharge to outdoor.It is online that oil droplet in this process in the part oil smoke is adsorbed onto wind, reduced the oil content in the flue gas, makes the flue gas of discharge obtain the part purification.Be adsorbed on the online oil of wind and flow in the oil storage box, its cleaning also is pretty troublesome.Because the mesh of wind net can not be very little, the twine or the shared area ratio of web plate of absorption oil smoke can not be very big, otherwise resistance increases the normal discharging that will influence flue gas.So in the flue gas that range hood is discharged, still contain the composition of big gauging.Not only pollute range hood itself, also atmosphere and environment have on every side been caused pollution.
Summary of the invention
The purpose of this utility model provides a kind of range hood of family kitchen fume purifying, and this range hood can purify up hill and dale to the oil smoke that family kitchen produces, and makes flue gas cleaning, the nothing oil of discharge, and environment is not polluted.
The utility model realizes that by following measure its operation principle is that a gas cleaning chamber is set, and on the exhaust gases passes in the clean room, is provided with water curtain on the range hood that blower fan and water pump are housed; The water that forms water curtain is the scavenging solution that is added with molten finish; When flue gas passed through water curtain under the effect of blower fan suction, the mist of oil in the flue gas contacted fully with scavenging solution, makes mist of oil all be dissolved in the scavenging solution; Flue gas after being purified is discharged to outdoor by blower fan; Eminence in the clean room is provided with the scavenging solution shower nozzle, and shower nozzle is sprayed onto scavenging solution on the inwall of clean room, cleans the greasy dirt on the inwall; The working method of this purification method is one of following dual mode: a, medium-sized be by key switch control blower fan and water pump unlatching, close, and manual operation is changed scavenging solution and is added molten finish; B, automatic type be signal controlling blower fan by Smoke Sensor and water pump unlatching, close, regularly change scavenging solution and add molten finish automatically.
A kind of range hood of family kitchen fume purifying mainly is made up of casing, blower fan, water pump and clean room, it is characterized in that: described range hood is the down smoke-discharging formula that blower fan is positioned at off the net of wind; Be provided with the gas cleaning chamber in the back of casing; The top of gas cleaning chamber is the wind net, and the middle part is provided with the flue gas division board of inclination; The high-end place of flue gas division board is connected with housing side wall, is provided with the scavenging solution shower nozzle above, is air inlet below; The end of flue gas division board low side is provided with drencher; The bottom of gas cleaning chamber is to purify liquid bath; The water inlet of water circulating pump is connected with the purification liquid bath, and delivery port is connected with drencher with the scavenging solution shower nozzle by pipeline; Purify liquid bath and be provided with upper hose, drainpipe and overflow pipe.
On the pipeline of pump outlet and scavenging solution shower nozzle or drencher, by-pass valve control is housed.In order to guarantee the effect of gas cleaning, flue gas is fully contacted with water curtain, the water curtain that drencher forms and the angle of horizontal plane can be adjusted.The range hood of automatic type is near the wind net above the casing table top Smoke Sensor to be housed, and on water inlet pipe, drainpipe and molten finish adding set magnetic valve is housed; Sensor, magnetic valve, blower fan and water pump are connected with control module; The signal controlling blower fan by Smoke Sensor and the unlatching of water pump, close, regularly change scavenging solution and add molten finish automatically.
During range hood work, the scavenging solution that is added with molten finish is transported to scavenging solution shower nozzle and drencher by water pump, and the scavenging solution shower nozzle is sprayed onto scavenging solution on clean room's inwall and the flue gas division board, cleans and adheres to superincumbent greasy dirt; Drencher then forms water curtain on the passage of flue gas process.Under the suction of blower fan, the oil-containing flue gas enters the clean room from the wind net, and the water curtain of process flue gas division board end enters blower fan.Through water curtain the time, the mist of oil in the flue gas contacts fully with scavenging solution, and mist of oil all is dissolved in the scavenging solution, and flue gas after being purified is discharged to outdoor by blower fan.
The beneficial effects of the utility model are that the oil smoke that family kitchen produces can fully contact with the scavenging solution that contains molten finish after entering the clean room of range hood, and the oil in the flue gas is dissolved in the scavenging solution fully, and it is purified.Scavenging solution can or regularly be changed according to the concentration of its oil-containing, to keep the effect of gas cleaning.Have simple in structure, practical and convenient, purification efficiency is high and the characteristics of energy-conserving and environment-protective, is applicable to purification and the discharge of family kitchen to flue gas.
