Description

Exhaust gas flue

The utility model relates to a kind of fume extractor, and is particularly a kind of with the outdoor discharge flue of the discharge of the oil smoke in the kitchen.

Existing exhaust gas flue generally comprises fume inlet passage, smoke-outlet flue and is arranged on the interior automatic valve of housing, housing is fixed on the body of wall, the air guide elbow that is connected with smoke-outlet flue is arranged in the main channel of smoke discharging of building, and the horizontal outlet flue of air guide elbow is provided with check (non-return) valve.This exhaust gas flue is work like this: oil smoke gas is in fume inlet passage, automatic valve, smoke-outlet flue and air guide elbow enter the smoke discharging main channel of building, and the effect of automatic valve and check (non-return) valve is to prevent that the oil smoke gas in the smoke discharging main channel of building is back to indoor.The exhaust gas flue of this structure is comparatively suitable for the little northern room of mist of oil, but its cost height, floor space is big, temperature tolerance is poor, low and the poor toughness of intensity, and be not suitable for the Sichuan cuisine kitchen and use, its reason is the edible oil temperature height of Sichuan cuisine, mist of oil is big, greasy dirt dyes heavily, the check (non-return) valve at elbow top is all dashed not open under the effect of smoke exhaust ventilator, lose the effect of unlatching, and it is not easy to clean, if the user stops drinking a period of time, check (non-return) valve and automatic valve are all clinged by the grease that refluxes in the smoke discharging main channel, thereby make valve closes bad, cause flue gas in the smoke discharging main channel to indoor backflow.

The purpose of this utility model just provides a kind of simple in structure, fume extractor that temperature tolerance is strong and easy for installation, and it can prevent the backflow of oil smoke gas effectively.

The purpose of this utility model is to realize by such technical scheme, and it includes fume inlet passage, smoke-outlet flue and is arranged on the interior automatic valve of housing, and it is characterized in that: fume inlet passage is provided with the flue gas cut-off equipment.The utility model is fixed on the body of wall, and fume inlet passage is communicated with the smoke exhaust ventilator outlet flue in kitchen, and smoke-outlet flue is communicated with the smoke evacuation main channel of building on the body.During use, open the flue gas cut-off equipment, the oil smoke in kitchen behind fume inlet passage, flue gas cut-off equipment, is washed automatic valve open under the effect of smoke exhaust ventilator, enters the smoke evacuation main channel of building on the body by smoke-outlet flue.When not needing to use, close the flue gas cut-off equipment, prevent to build in the oil vapor backstreaming inlet chamber in the smoke evacuation main channel on the body.

Owing to adopted technique scheme, the utlity model has simple in structure, low cost of manufacture, easy for installation, temperature tolerance strong and advantage such as long service life, it can prevent the backflow of oil smoke gas effectively, makes it have characteristics such as intensity height, light weight, fire prevention, waterproof, anti-cracking and anti-aging because of adopting five anti-light body wallings.
