Description

A kind of oil suction cigarette device with the U-shaped smoke extracting tube

Technical field: the utility model relates to a kind of gas exhaust device, definite a kind of oil suction cigarette device with the U-shaped smoke extracting tube of saying so.

Background technology: nowadays along with the raising of people's living standard, household smoke exhaust ventilator is more and more universal, makes the air of family not be subjected to fume pollution.But existing as dark type direct absorbing type smoke exhaust ventilators such as " handsome health ", " side too ", " field, village ", the problem that the ubiquity mounting distance is too high relatively, far away excessively from the cigarette source, 40% the oil smoke of having an appointment flies away in uphill process, pollutes indoor.In order to solve this contradiction, each manufacturer has taked the measure of expanded motor power, not only power consumption, and effect is also undesirable.In addition, the motor of direct absorbing type smoke exhaust ventilator, blade and correlated parts all place flue, and greasy dirt incrustation situation is serious, have increased the starting load of motor, and noise strengthens, and has greatly influenced smoke exhaust efficiency.Simultaneously, greasy dirt has corrosiveness to motor, blade and electric wire, very easily forms short circuit, influences complete machine service life.Above-mentioned direct absorbing type smoke exhaust ventilator also has dismounting inconvenience, cleans the problem of difficulty, must could carry out dismounting to it by the professional and clean, otherwise will destroy the motor dynamic balancing, has aggravated the expansion of noise, and serious meeting directly causes the damage of smoke exhaust ventilator.

Summary of the invention: the purpose of this utility model exactly in order to address the above problem, provides a kind of mist extractor efficient height, little, the less energy consumption of noise, and the oil suction cigarette device of long band U-shaped smoke extracting tube of exempting to unpick and wash of life-span.

Technical solution of the present utility model is: a kind of oil suction cigarette device that the utility model relates to the U-shaped smoke extracting tube, form by the smoke evacuation person in charge, the air intake person in charge, cabinet and U-shaped smoke extracting tube and smoke-choking plate, and it is characterized in that:

1. cabinet of the present utility model is made up of cabinet upper cover, centrifugal blower and cabinet casing, wherein the cabinet upper cover is provided with upper cover smoking port and power switch, the cabinet casing is divided into three airtight casings by internal partition, the centre is a negative pressure collection smoke box, both sides are respectively left and right headstocks, and high-speed electric expreess locomotive and centrifugal blower are installed in the headstock; Headstock top is provided with air intake connection pipe, and communicates with the air intake person in charge, and the bottom has fan outlet, is connected with the U-shaped smoke extracting tube; Smoke evacuation is responsible for the outer air intake that is with and is responsible for, and is three-back-shaped structure, and an end and cabinet upper cover are connected and fixed, and outdoor outlet flue is higher than 1 meter of air intake person in charge opening.

2. the cabinet below is provided with 2 U-shaped smoke extracting tubes arranged side by side, and the air inlet of U-shaped smoke extracting tube is communicated with fan outlet, and U-shaped smoke extracting tube air outlet stretches in the negative pressure collection smoke box, and communicates with the smoke evacuation person in charge by smoke exhaust pipe in the negative pressure; Have 20-60 bar shaped smoking port on the outer facade of U-shaped smoke extracting tube, each smoking port all is provided with the intilted deflector that keeps out the wind.

3. the lateral surface at 2 U-shaped smoke extracting tubes is respectively equipped with two fan smoke-choking plates, is connected and fixed by detachable hinge between smoke-choking plate and the U-shaped smoke extracting tube, and the minimum point of U-shaped smoke extracting tube is equipped with the drawer type oil collection box.

The utility model has adopted and the diverse structural design of existing direct absorbing type smoke exhaust ventilator, be to have utilized centrifugal blower in the U-shaped smoke extracting tube, to produce the jet-stream wind of high-voltage high-speed, produce air pressure difference (negative pressure) at the smoke extracting tube interior or exterior space, form negative pressuren zone, the oil smoke of outside can be sucked the U-shaped smoke extracting tube, and be discharged to outdoor through the negative pressure collection smoke box and the smoke evacuation person in charge by high velocity air.Compared with prior art, the utlity model has following advantage:

A. the efficient of smoking improves greatly.Because the installation site of U-shaped smoke extracting tube is very near from the cigarette source, minimum smoking port is from kitchen range top 100mm only, and smoking port quantity is a lot, adds collection smoke box smoking port and upper cover smoking port on the cabinet, can guarantee in oil smoke rises the way it all to be sucked smoke extracting tube.After choke plate opens in addition, oil smoke is accumulated in the hemi-closure space, prevent that it from spreading to both sides, be convenient to smoke extracting tube suction oil smoke, also prevent that indoor air flow from producing the flow-disturbing influence to oil smoke simultaneously, thereby improved the efficient of pump drainage oil smoke.Through the reality measuring and calculating, smoking efficient of the present utility model reaches more than 95%, has guaranteed that basically human body and indoor environment are not subjected to fume pollution.

B. the life-span long, exempt to clean.Because high-speed electric expreess locomotive, centrifugal blower and interlock circuit are sealed in the headstock, air intake is responsible for openend again outdoor, what suck is the fresh air that does not contain oil smoke, make said apparatus not contact oil smoke steam, oil smoke incrustation and etching problem have fundamentally been solved, reduce the fault rate of motor, thereby prolonged the service life of motor.

C. volume compact, noise is little, and it is low to consume energy.Existing smoke exhaust ventilator all has a common disadvantage, is exactly that the bodily form is bigger, and the position is just in time facing to people's head, and people do not note slightly damaging head or eye are very dangerous.Profile of the present utility model is flat, and thinnest part thickness is 60mm only, and thickness thickness is 180mm, and far away from human body, so very safe.Because maximum noise source-blower fan of the present utility model is in the airtight headstock, has completely cut off noise; Because it is blower fan is directly to be contained on the wall, very little again with the cabinet contact-making surface, can not produce vibration, thereby prevent that casing from producing noise because of vibration.The employed high-speed electric expreess locomotive of the utility model, single-machine capacity is 70W only, the highest 400W that reached of the power of present direct absorbing type smoke exhaust ventilator, energy-saving effect is very obvious by contrast.

The utility model is simple in structure, and cost is low, and production technology is uncomplicated, and fume exhaust efficient height, and it is low to consume energy, and noise is little, and is safe, is the desirable regeneration product of existing smoke exhaust ventilator.
