Abstract
The utility model relates to a household novel cooking fume filter. The design is characterized in that a strong airflow barrier for isolating atmospheric pressure is generated on a circumference opening below a complete machine. An air zone of negative pressure of one cubic meter is formed between double stove plates. Cooking fume is forced to be filtered in a concentrating mode and is discharged. A cooking fume channel of a machine body is not discharged through the interior of the machine body, but through an inner sleeve and an outer sleeve which are used for isolating the interior of a main machine. The diameters of the inner sleeve and the outer sleeve are not the same. A distance between the inner sleeve and the outer sleeve is a negative pressure zone of an air discharge opening for cooking, forming discharge attraction force. A cooking fume filtering net of a centrifugal type exhaust fan is arranged in an inner sleeve of the air discharge opening. The cooking fume is thrown in an accumulative speed mode into an oil collecting ring groove under centrifugal force action generated from the high running filtering net. Filtered gas is directly discharged outdoors.
Description
The utility model relates to family kitchen oil strain cigarette, rejection flavor, fall high temperature, exempt and unpick and wash greasy dirt, practical a kind of new structure air negative pressure formula filter lampblack absorber.
In the design of prior art ZL (93206613.5) gas cover type smoke exhaust ventilator is described, form by fume exhaust device and gas hood generator two parts.During smoke exhaust ventilator work, the gas hood generator produces airhood, has formed producing shrouding of oil smoke in the cooking process, has limited the oil smoke diffusion and has focused on fume absorbing openings, makes it siphon away discharge in the strong suction scope.
More than design and function have weak point: because this design does not have lampblack filter, the oil smoke passage makes 1. motor main shafts and 3. smoke exhaust ventilator impellers be subjected to oil smoke dirty long-pending, decay body performance, this design is from the 2. oil smoke passages outdoor air of directly having discharged fume pollution.The air-flow of discharging from 13. gas hood mouths is annular negative pressuren zone, and the oil smoke area that existing market twin furnace dish kitchen range is produced does not reach the whole gas hoods of oil smoke, and its negative pressuren zone area is too little, makes the soot gas sinuous flow indoor easily.
The purpose of this utility model is in order to overcome the above-mentioned shortcoming of existing designing technique.The design inhales for solving, the mist extractor filtration channel, does not filter oil smoke by motor in the body and wind wheel and discharges outdoor.
The utility model its feature: with having design and product now is diverse structure.Be to enter body internal gas pressure chamber by two groups of centrifugal blast machines inspiration simultaneously body outer air, motor and wind wheel form than strong gas pressure in air pressure office work, and following mouth ejects and reaches 80 centimeters gas jet around the rectangle body.Around twin furnace dish kitchen range cooking area, isolate the air atmospheric pressure, formed a 1M
3The air negative pressure district.
The design has installed the filtering oil smoke passage of two groups of main frames of a kind of isolation in the body air-pressure chamber, it is by two internal and external channel sleeves that diameter is different, be exhaust outlet apart between interior cover and the overcoat, from exhaust, penetrate passage under the strong gas pressure in body, thereby make the oil smoke air negative pressure district of culinary art form a kind of gravitation of taking out.And a kind of centrifugal exhausting fan filtering oil smoke net of device in exhaust outlet, overlapping, it produces centrifugal action in the high speed rotating of micro-machine, make oil smoke dirty long-pending, speed is thrown in the oil-collecting annular groove, make whole removing in the process of oil smoke, all the time can not pollute inside and outside the body, it is long-pending to filter the greasy dirt that extracts the back, as long as the cleaning and filtering net.
It can solve the design well and need not unpick and wash the inside and outside greasy dirt of body, only needs a cleaning and filtering net to get final product.Its energy oil strain cigarette during culinary art, high temperature falls in the rejection flavor, is a kind of family utility model filter lampblack absorber.
The schematic configuration diagram of following examples is to this practical further specifying:
Overlap outer cage Luo silk connecting rod 13. exhaust fans 14. air-pressure chambers 15. outer cages top air inlet 16. blast machine exhaust outlets in 12. in 11. times oil strain cigarettes of exhaust overcoat on 7. annular oil trap 8. centrifugal blast machine 9. alternating current generators 10. of 1. outer cage 2. inner casings, 3. peripheral airflow orifice 4. ring property exhaust outlet 5. centrifugal filtration nets, 6. direct current generators (12v) among the figure
The utility model embodiment:
This casing inner structure: form two groups of electric centrifugal-type blast machines with 8. centrifugal blast machine 9. alternating current generators, blast machine air inlet places 15. outer cages top, two air inlets, two groups of blast machines be placed in 1. outer cages, 2. inner casings up and down between when working the direct air draft of 16. blast machine exhaust outlets make and add atmospheric pressure in the casing, make inner 14. air-pressure chambers that form, and to peripheral 3. airflow orifices in body below, mouth penetrates air-flow apart from being 0.5 centimeter, make the complete machine below produce peripheral air blast barrier separating atmospheric and press, and form about 1 cubic metre air negative pressure district between the twin furnace dish.The gas that produces in the machine also penetrates from 4. annular row gas ports simultaneously, makes main frame in the oil smoke channel separation machine, and has formed a kind ofly in the filtering oil smoke import, has powerful air-flow to take out gravitation, and the gas after the filtration is discharged outdoor.
The design's oil strain cigarette part: form up and down each sleeve at 1. outer cages, 2. inner casing centers and be nested and form, cover 10. is the exhaust overcoat on the casing, casing traps 11 for overlapping in the oil strain cigarette, 2 centimeters Ullages are arranged between being nested, form 4. annular row gas ports, below the complete machine body peripheral 3. airflow orifice places with 12. in outer cage Luo silk connecting rod connect in outer cage form integral body, configuration 6. small-sized ac-dc power supply 12V (direct current generator 12V) connect 13. exhaust fans, 5. centrifugal filtration nets composition filtering oil smoke net arrangement in the cover in 11. oil strain cigarettes.
The filtering oil smoke net is when running up, and oil smoke is thrown under centrifugal action on the inwall that overlaps in the 11. oil strain cigarettes, flows downstream in the 7. annular oil traps again, and the gas after the filtration is discharged outdoor in the strong suction force of 4. annular row gas ports rapidly,
This design complete machine is made inside and outside shell material based on sheet metal, and the complete machine size is of a size of reference with the twin furnace dish kitchen range of producing on the existing market.
