The cleaning of impeller and motor output end face needs to remove earlier impeller, and from top dismounting motor, blade rigid is low again, and this gives again and tears, washes, adorns the increase difficulty open.The spiral case inner surface since long-pending oil can not arrange, of long duration it, the very thick one deck that will condense, more difficult removing.Comprehensively above-mentioned, present polytype smoke exhaust owing to structural reason, can't solve above two difficult problems that people pay close attention to most.
The purpose of this utility model is to solve problems of the prior art, provides a kind of suction, row effective, pollutes for a short time, and it is convenient to clean, i.e. the suitable again oil soot exhaustor of economy.
Technical solution of the present utility model is: by exhaust fume collecting hood (1), exhaust blower (2), motor (10), spiral case (3), exhaust duct (4) is formed, of the present utility model be characterised in that above-mentioned exhaust fume collecting hood (1) be umbrella shape make its flue gas flow direction and cover mouthful suck an air flow direction to conform to, be furnished with exhaust blower (2) and the motor (10) that is assemblied in the spiral case (3) on the top of above-mentioned exhaust fume collecting hood (1), at the exhaust outlet place of spiral case (3) exhaust duct (4) is housed, the exhaust outlet downside (7) of above-mentioned spiral case (3) is made skewed, dispose one at the air inlet of spiral case (3) and can prevent oil, water flows to the oil baffle (5) of exhaust hood inner surface, be equipped with the V-type dividing plate (8) that can roll on the top of spiral case (3), motor (10) exhaust blower (2) is assemblied in the V-type dividing plate (8).
The utility model is when adopting the said structure scheme, successfully used air fluid mechanics optimal design principle, straight suction, in line purpose have been realized, compared with similar products, has the exhaust efficiency height, pollution discharge capability is strong, long-pending oil and exhaust are in same runner, and by the clumsy air velocity of row, having finished the long-pending oil of the interior nothing of spiral case more up hill and dale condenses, this peculiar exhaust is discharged incorporate totally-enclosed air channel design with long-pending oil, has realized no draining hole and oil collection box in the machine, provides convenience to scouring.
Below be that Figure of description is briefly explained.
Fig. 1 is the main pseudosection of smoke exhaust.
Fig. 2 is the vertical view of smoke exhaust.
Fig. 3 is the left view of smoke exhaust.
Fig. 4 is the scheme of installation that slight V font connects for the smoke exhaust exhaust duct.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing;
The design brings on the basis of harm in varied culinary art gimmick and eating habit and fuel band variation, for reducing and improve harmful gas pollution, for cleaning convenient more satisfactory suction, the exhaust lampblack absorber efficiently that proposes.It is inhaled, grate flow channel is reasonable, and capacity is big, and the dirty particulate of isolated half liquid, half gas and oil can directly be discharged in the machine, cleans simply the oil soot exhaustor that applicability is strong.Umbrella hood (1) has covering uneven suction velocity function of gas generation down, and cover mouthful cross sectional shape is similar to the kitchen range floor projection again.During the pernicious gas come-up that gives out when kitchen range, it flows to a cover mouthful suction air flow direction and conforms to again, so umbrella hood is with regard to the pernicious gas under the absorption cover of instinct.The design, directly sucks the pernicious gas of vertical lifting without gyration under the effect of high-power centrifugal exhaust blower (2) by means of the gas collection function of umbrella hood.And the pernicious gas of discharging directly enters exhaust duct (4) from spiral case (3).The drag losses of air draft has not only been reduced in this advanced air fluid air channel, has reduced again that to be stained with pasta long-pending, has realized the purpose of straight suction, in line efficient mist extractor, and this compares with the smoke exhaust that adopts the same model exhaust blower, has saved the energy, has increased exhaust air rate.For conveniently cleaning and alleviate the scouring difficulty, the downside planar design of spiral case (3) is become skewed, promptly than the low 10mm of spiral case exhaust outlet, the air inlet oil baffle (5) of spiral case (3), high 8mm, its diameter is less than profile ID 6mm.Impeller rotates isolated oil, water along incline direction, flows directly in the terminal outage of exhaust duct (4).Greasy dirt purges by wind-force again, can not condense in the spiral case, and oil baffle (5) can prevent that oil, water from flowing to the inner surface of umbrella hood, has realized that long-pending oil effluxes, and no draining hole and oil collection box in the body are provided convenience for cleaning umbrella hood.Fixed its cleaned impeller, and this is also very simple, as long as 6 screws (9) on the V-type dividing plate (8) are unclamped, motor (10) and impeller (2) can wholely take out and carry out.Clean the cycle and guarantee ventilation efficiency for prolonging impeller; it is the spray facilities (11) such as miniature immersible pump, detergent solution box and shower nozzle of 18W that the casing top is equipped with a cover power; be used in after the cooking operation; before the shutdown; when the inner surface of impeller and umbellate form cover also was in higher temperature, the isolated oil of blade, water did not also condense, and carry out spray irrigation; waste liquid flows to outage, also cleans for smooth umbrella hood inner surface and provides convenience.Comprehensively above-mentioned: the gas circuit and the oil circuit of the design of this machine, carry out in spiral case by entering out entirely.Because flow passage design, zero, the globality after connecting between the parts is strong, convenient for dismounting and washing, do not have the oily part of leakage.Especially can be stained with the scrappy of oil, as: draining hole, oil collection box, guard, all decorative panels of lamp etc., all there be not direct or indirect contacting with oil, gas, so the inner surface of umbellate form cover is smooth, to clean simply, this is that other type is incomparable.For making the fresh smoothness of room air, under the situation of opening the door, windowing, can cook.The ad hoc jet-stream wind screen of this machine facility (12), the jet-stream wind screen is made up of 20W blower fan and distributing pipe, and playpipe is arranged on leading edge and the right and left of umbrella hood.For saving the energy and guaranteeing jet-stream wind screen effect.According to the installation site, can block by metope distributing pipe on one side, the airflow direction of jet-stream wind screen from top to bottom, last face velocity is big.The pernicious gas that kitchen range give out because buoyancy is arranged, flowing velocity is following big, when vertical lifting behind certain altitude, become floating smog random, no speed, wherein most ofly sucked, and the marginal portion is shielded by air-flow and is sealed, and can not loose outward by induced-draught fan.Simultaneously prevented that again indoor air flow from sealing in, improved suction, mist extractor effect.Spring thrust card (6), the location dimension in the time of can guaranteeing the impeller installation and the safety effect of slip-off preventing.
