Description
Technical field
The present invention relates to kitchen articles, relate in particular to a kind of Whirlwind type oil fume fume exhauster.
Background technology
The kitchen is the most serious space of air pollution in the family, and its pollution source mainly contains two aspects; The one, with pernicious gases such as the carbon monoxide that discharges in coal, coal gas, the liquefied gas fire used for cooking commonly used, carbon dioxide, sulfur dioxide, nitrogen oxide; The 2nd, the oil smoke that produces during dish-cooking.Present kitchen finishing open by design that adopt, but the process of making Chinese meal can produce bigger oil smoke more, open kitchen, the air flow range is bigger, the lampblack absorber discharging oil smoke of can not amassing wealth by heavy taxation well, this has just caused the oil flue waste gas in dining room and parlor to pollute.
Range hood is a kind of kitchen appliance that purifies kitchen environment.It is installed in kitchen range top, the harmful oil smoke that produces in the refuse of cooking stove burning and the cooking process can be taken away rapidly, discharges outdoorly, reduces pollution, purifies air, and gas defence, explosion-proof safety guarantee effect are arranged.Smoke exhaust ventilator has become the requisite cooking apparatus of Modern Family.Early stage family kitchen smoke evacuation work is all finished by ventilating fan.Though ventilating fan can exclude the most of oil smoke in the kitchen, the oil smoke that produces in its unable solution culinary art is to whole kitchen pollution.The oil smoke that produces in the culinary art contains a lot of harmful materials, if the people works in being full of the room of oil smoke for a long time, can cause the generation of a lot of diseases.
For Chinese, diet structure is different with the westerner, in food processing, Fried, fried, cooked, fried occupy very big ratio, therefore the oil smoke in the Chinese style kitchen is very big, make the kitchen environment greasy and bad cleaning that becomes easily, so smoke exhaust ventilator has just become to change one " powerful mean " of kitchen environment.It has changed the overall situation in kitchen, reduces oil smoke kitchen environment and health are damaged; Smoke exhaust ventilator is kitchen " lung ".
And now the cooker hood ubiquity efficient on the market is not high, easily stop up, and easy cleaning not, filter screen needs often to clean or change, and uses suction can descend the degradation shortcoming for a long time, so seek very necessity of range hood that more environmental protection saves worry.
Summary of the invention
Goal of the invention:, the invention provides and a kind ofly the high purifying rate cooker hood of discharging behind the fume purifying can be able to be effectively reduced the pollution of kitchen fume to environment in order to overcome the deficiencies in the prior art.
Technical scheme: for solving the problems of the technologies described above, the technical scheme of the present invention's sampling is:
A kind of Whirlwind type oil fume fume exhauster, comprise horizontal fixed and be positioned at kitchen range top top petticoat pipe, air intake duct, blower fan, blast pipe, be installed in the oil collection box on the petticoat pipe, transfer tube and cyclone separator; Described petticoat pipe is provided with the outlet of oil smoke import and oil smoke, described transfer tube two port surfaces perpendicular; Described cyclone separator is vertically installed, its inner chamber top is cylindrical shape, the bottom is conical, on cyclone separator, be provided with air inlet, gas outlet and oil drain out, air inlet is located on top, columnar side, and air inlet is positioned at the tangential direction of cylindrical cross-section, can do the circumgyration campaign along columnar inwall when making gas enter cyclone separator by air inlet, the gas outlet is located on the columnar upper surface, and oil drain out is located on the small end actinal surface of conical lower end; Described air intake duct vertically is installed on the convergent point of oil smoke, oil smoke outlet on one end and the petticoat pipe is connected, the other end is connected with the air inlet of cyclone separator by transfer tube, oil smoke is introduced cyclone separator, described oil collection box is positioned at the cyclone separator below, venthole is connected with fans entrance by connecting leg, and the blower fan outlet is connected with blast pipe.
Petticoat pipe is fixed on the wall of kitchen range top top, is used to collect oil smoke, reduces the dissipation of oil smoke, and its inner chamber is for the benefit of collected the taper of oil smoke, and the large port of taper is the oil smoke import of petticoat pipe, and the portlet of taper is the oil smoke outlet of petticoat pipe; Simultaneously, petticoat pipe is also as main load-supporting part.
Can design air intake duct is pipe, and the air inlet of cyclone separator is square interface, and at this moment, transfer tube need be designed to the transfer tube into circle commentaries on classics side, so that air intake duct is connected with cyclone separator.
Described cyclone separator is main cleaning equipment, and its number is one or more; Venthole on the cyclone separator is a circular hole, and its diameter is less relatively, when connecting leg is connected with the venthole of cyclone separator, needs to insert cylindrical interior appropriate depth; Can be provided with the oily dirt free coating on the wall of chamber within it, avoid cleaning.
Described blower fan fixed installation can be arranged on the petticoat pipe, and it is mainly used in provides power and form negative pressure.Blast pipe connects the blower fan outlet, is used to discharge cleaned air passes; The blower fan postposition can be protected blower fan simultaneously.
Described oil collection box is installed in cyclone separator bottom, is used to collect separated liquid oil, and it can be installed on the petticoat pipe by buckle structure or helicitic texture, so that fluid is poured out in frequent dismounting; Described oil collection box preferably clear material is convenient to observe oil mass, in time handles.
During work, blower fan runs up, shift air onto exhaust outlet always, atmospheric density in the fan air inlet side system can sharply reduce, promptly can produce big pressure falls, therefore the air pressure of internal system is significantly less than extraneous air pressure, and under the effect of this draught head, oil smoke is along with air-flow enters cyclone separator.When soot gas enters cyclone separator by air intake duct by the tangential admission mouth with the speed of 12～35m/s, air-flow will become circular motion by rectilinear motion.The overwhelming majority of swirling eddy is downward twist from cylinder along wall, flows towards cone, claims that usually this is outer rotational gas flow.Soot gas produces centrifugal force in rotary course, the oil droplet of density greater than air got rid of to wall, and oil droplet is in case contact with wall, just loses inertia and leans on the momentum of entrance velocity and downward gravity to fall along wall, enters oil collection box through oil drain out.The outer rotational gas flow that rotation descends is when arriving cone, because of conical contraction is drawn close to the cyclone separator center, according to " spin moment " invariance principle, its tangential velocity improves constantly, when air-flow arrives a certain position, cone lower end, promptly focus on the cyclone separator middle part, the shape of from bottom to top continuing to spin motion, promptly interior rotational gas flow with same direction of rotation.Air after the final purification successively through the gas outlet, connecting leg, blower fan, blast pipe discharge.
Beneficial effect: Whirlwind type oil fume fume exhauster provided by the invention, simple in structure, device body movement-less part and easy consumptive material do not need special auxiliary device, make, install small investment; Its operation, easy to maintenance, and stable performance, suction is constant, sustained; Fume purifying efficient height can improve cooking environments, and the protection health reduces environmental pollution.
