Abstract
A jet flow, negative pressure and blowing guide kitchen fan comprises a fan, a collecting oil smoke cover and an exhaust oil smoke tube. The fan is positioned on the outlet part of the exhaust oil smoke tube, and connected with the colleting oil smoke cover by the exhaust oil smoke tube; the wind outlet of the fan is positioned with the exhaust oil smoke tube at a 80 degree to 100 degree angle; at the wind outlet of the exhaust oil smoke tube is arranged a negative pressure piece. When working, the oil smoke waste gas is directly discharged to the outdoors through the exhaust oil smoke tube which does not pollute the fan blades and does not need clean frequently. Because on the exhaust oil smoke tube and the wind outlet of the fan is added the negative pressure piece and the jet flow tube, the eddy flow phenomenon formed on the inner wall of the exhaust oil smoke tube is conquered; large triggering power can directly discharge the oil smoke waste gas to the outdoors; with the advantages of cleanness and hygiene, the operating effect is very rational. The kitchen fan has less power consumption, larger discharging quantity, and less working resistance.
Description
Technical field
The utility model relates to oil smoke gas remover apparatus, particularly a kind of jet, negative pressure, suction guide type smoke exhaust.
Background technology
Existing family expenses smoke exhaust can be divided into two types basically, a kind of is the smoke exhaust that is provided with blower fan, this smoke exhaust is as long as the oil flue waste gas that a startup is taken out slips over from the surface of flabellum, motor or impeller earlier, make fan blade inevitably be stained with greasy dirt, need often to clean, bother very much, also influence the service life of blower fan simultaneously.Another kind is a smoke exhaust of not establishing blower fan, and it only is the smoke evacuation power of the hot gas lift formation of oil smoke gas in the cooking casing, discharges through gas skirt, smoke exhaust pipe, and it is limited in one's ability to discharge fume.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of blower fan is placed on oil extraction smoke pipe export department position, when blower fan rotates, form jet wind, wind is from the top of oil extraction smoke pipe and skim on every side, making in the oil extraction smoke pipe becomes negative pressure state, and oil flue waste gas is directly drawn outdoor, jet, negative pressure, suction guide type smoke exhaust that result of use is desirable.
The purpose of this utility model is achieved in that and comprises blower fan, oil-collecting petticoat pipe, oil extraction smoke pipe that it is characterized in that, blower fan is arranged on the outlet position of oil extraction smoke pipe, is connected with the oil-collecting petticoat pipe by the oil extraction smoke pipe; The air outlet of the air outlet of blower fan and oil extraction smoke pipe is 80 ° of-110 ° of settings, and the air outlet place of oil extraction smoke pipe is equipped with negative pressure tongue and jet pipe.
Compared to existing technology, the utility model has the advantages that; Scientific structure design is reasonable, and during work, oil flue waste gas is directly discharged outdoor by the oil extraction smoke pipe, do not pollute flabellum, need not frequent cleaning.Owing to installed negative pressure tongue and fallopian tubal additional at oil extraction smoke pipe and fan outlet place, overcome the phenomenon of mist extractor inside pipe wall formation eddy current, result of use is very good, clean hygiene.This machine power consumption is little, and exhaust air rate is big, and working resistance is little.
The explanation of accompanying drawing drawing
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation that the utility model adopts the transverse tube type blower fan.
The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is made up of blower fan 5, oil-collecting petticoat pipe 1, oil extraction smoke pipe 2.As Fig. 1, blower fan 5 is arranged on air outlet 7 positions of oil extraction smoke pipe 2, is connected with oil-collecting petticoat pipe 1 by oil extraction smoke pipe 2.The air outlet 6 of blower fan 5 is 80 ° of-110 ° of settings with the air outlet 7 of oil extraction smoke pipe 2, and the air outlet 6 of the utility model blower fan 5 is 90 ° of settings perpendicular to the air outlet 7 of oil extraction smoke pipe 2, at air outlet 7 places of oil extraction smoke pipe 2 negative pressure tongue 3 and jet pipe 4 is installed.Negative pressure tongue 3 is plugged on the oil extraction smoke pipe 2, and jet pipe 4 is perpendicular to fan outlet 6.This set when blower fan 5 rotates, under the effect of jet pipe, forms jet wind, from the top of oil extraction smoke pipe 2 with skim over, makes formation negative pressure state in the oil extraction smoke pipe 2 on every side.Being provided with of negative pressure tongue 3 strengthened the interior negative pressure and the initiation power that is pulled outwardly wind of oil extraction smoke pipe, makes the oil smoke in the exhaust fume collecting hood 1 directly guide to outdoor with jet wind.The utility model can be according to the actual design requirement, selects the pattern of blower fan 5, can adopt its structure of box type fan such as Fig. 1, and its flabellum places in the casing, and it is little that its advantage is that compact conformation takes up space.Can also adopt transverse tube type blower fan 5, its structure such as Fig. 2, its flabellum place in the transverse tube 8, and its advantage is that manufacturing process is simple.
Operation principle of the present utility model: start blower fan 5, blower fan 5 rotates.Because the air outlet 6 of blower fan 5 is perpendicular to the air outlet 7 of oil extraction smoke pipe 2, and negative pressure tongue 3 and jet pipe 4 be installed at the air outlet place, blower fan 5 one changes, will form jet wind, jet wind is from the top of oil extraction smoke pipe 2 and skim on every side, make in the oil extraction smoke pipe 2 to be in negative pressure state, the oil smoke in the exhaust fume collecting hood 1 together is blown away with jet wind.Under the effect of negative pressure tongue, negative pressure in the oil extraction smoke pipe pipe and outside initiation power strengthen, and oil flue waste gas is directly discharged from oil extraction smoke pipe 2 without the impeller of fan blade, motor.
According to architectural feature of the present utility model, can make series of products.Both can be used as range hood, the air draft of the factory of also can doing manual work, smoke evacuation are used.
Claims (4)
1, a kind of jet, negative pressure, suction guide type smoke exhaust comprise blower fan, oil-collecting petticoat pipe, oil extraction smoke pipe, it is characterized in that, blower fan is arranged on the outlet position of oil extraction smoke pipe, are connected with the oil-collecting petticoat pipe by the oil extraction smoke pipe; The air outlet of the air outlet of blower fan and oil extraction smoke pipe is 80 ° of-110 ° of settings, and the air outlet place of oil extraction smoke pipe is equipped with negative pressure tongue, jet pipe.
