Abstract

The utility model relates to an up-draught conical full-air-curtain split-type injection range hood, which is mainly formed by that: an annular jet-air pipe with the diameter being more than that of an opening of a frying pan and with a jet-air port with an inclination angle is arranged at the position which is slightly lower than the opening of the frying pan through three supporting hooks which are uniformly distributed on the circumference, and the annular jet-air pipe is connected with a blower through a lower connecting air pipe. An oil collecting hood component, and a reducing-enlarging pipe and an oil discharging smoke pipe, which are connected with the oil collecting hood component, are arranged inside a range hood shell, a jet-air nozzle is installed at a throat opening of the reducing-enlarging pipe, and the reducing-enlarging pipe is connected with the blower through an upper connecting air pipe. When the blower works, the airflow is sprayed out respectively from the jet-air port and the jet-air nozzle, the airflow which is sprayed out from the jet-air port forms a conical air curtain, and negative pressure is formed at the throat opening of the reducing-enlarging pipe, and the airflow which is sprayed out from the jet-air nozzle forms the negative pressure. The oil smoke which is closed inside the conical air curtain is discharged under the collective effect of the drainage of a flowing air curtain and the negative pressure. The range hood has the advantages of simple structure, convenience in assembling, easiness in washing, energy conservation, electricity conservation, no leakage of oil smoke, thorough discharging of smoke, small noise and the like. The market prospect of the range hood is promising.

Description

On blow the split type injection smoke exhaust ventilator of conical full blast curtain
Affiliated technical field
The utility model relates to the technical field of household kitchen smoke exhaust ventilator.
Background technology
Existing smoke exhaust ventilator is the swabbing action suction oil smoke that utilizes the vane type ventilating fan, oil smoke is directly discharged by force by blade, motor, air channel, have that power consumption is big, the big drawback of operation noise, and lengthening along with service time, increase attached to greasy dirt on blade, rotating shaft, motor, the wind path wall, power and noise can continue to increase, and greasy dirt cleans extremely inconvenience.
Summary of the invention
The utility model provides and blows the split type injection smoke exhaust ventilator of conical full blast curtain on a kind of, and the annular blast pipe that will have an air nozzle colludes by the supporting of three circumference uniform distributions and places a little less than frying boiler port, and links to each other with blower fan by connecting airduct down.The smoke exhaust ventilator shell is built-in with oil-collecting petticoat pipe assembly, convergent-divergent pipe, oil extraction smoke pipe, blower fan, and air blast beak is equipped with at convergent-divergent pipe aditus laryngis place, links to each other with blower fan by last connection airduct.During blower fan work, air-flow is respectively from air nozzle and air blast beak ejection, and the air-flow of air nozzle ejection forms conical air curtain and forms negative pressure at convergent-divergent pipe aditus laryngis place, and the air-flow of air nozzle ejection also forms negative pressure.The oil smoke that is enclosed in the conical air curtain is discharged under the acting in conjunction of flow air curtain drainage and negative pressure.This lampblack absorber have cleaning simple in structure, easy to assembly, easy, energy saving, oil smoke do not leak, discharge fume clean thoroughly, serial advantage such as noise is very little, be a kind of smoke exhaust ventilator new product that market prospects are arranged very much.
Above-mentioned purpose is achieved through the following technical solutions:
Diameter has certain angle of inclination greater than frying pan bore and air nozzle annular blast pipe colludes by the supporting of three circumference uniform distributions and places a little less than frying boiler port, and links to each other with blower fan by connecting airduct down.The smoke exhaust ventilator shell be built-in with oil-collecting petticoat pipe assembly with its convergent-divergent pipe that is connected in succession and oil extraction smoke pipe, dress air blast beak in convergent-divergent pipe aditus laryngis place links to each other with blower fan by last connection airduct.During blower fan work, a part of air-flow sprays from the series inclination air nozzle on the annular blast pipe, forms conical air curtain, enters the convergent-divergent pipe and form negative pressure in aditus laryngis place flow at high speed under the guiding of oil-collecting petticoat pipe; Another part air-flow sprays at a high speed from the aditus laryngis air blast beak and also forms negative pressure.Be enclosed in the oil smoke in the conical air curtain, under the acting in conjunction of flow air curtain drainage and the dual negative pressure in aditus laryngis place, discharge with air-flow through oil-collecting petticoat pipe assembly, convergent-divergent pipe, oil extraction smoke pipe.
This technical scheme has following beneficial effect:
1, the utility model blows the split type injection smoke exhaust ventilator of conical full blast curtain on being, only needs outside the oil extraction smoke pipe blower fan to be installed, and does not need other power-equipments, has the advantage of cleaning simple in structure, easy to assembly, easy, energy saving.
2, the utility model can be enclosed in the oil smoke that cooking produces in the conical air curtain, and directly discharge under the acting in conjunction of and negative pressure drainage mobile at the air curtain that flows, smoke discharging effect is better, and oil smoke is not easy diffusion in the kitchen, spreads, home environment is environmental protection more, is easy to promote the use of.
3, the utility model is in useful life period, and the main dynamics equipment blower fan can not be subjected to the influence of fume pollution basically, has that power and noise remain unchanged, the characteristics of long service life.
4, the blower fan in the utility model can be controlled the air-flow of air blast beak and the ejection of annular blast pipe separately, also can control the air-flow of air blast beak and annular blast pipe ejection simultaneously.The oil smoke that produces when cooking relatively hour only need be opened blower fan from air blast beak or annular blast pipe ejection air-flow; When oil smoke is relatively large, then open blower fan simultaneously from air blast beak and annular blast pipe ejection air-flow, be a kind of energy-conservation, design easily.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Diameter has certain angle of inclination greater than frying pan bore and air nozzle 14 annular blast pipe 15 colludes 13 by the supporting of three circumference uniform distributions and places a little less than frying boiler port, and links to each other with blower fan 10 by connecting airduct 12 down.Smoke exhaust ventilator shell 7 be built-in with oil-collecting petticoat pipe assembly 3 with its convergent-divergent pipe 4 that is connected in succession and oil extraction smoke pipe 8, dresses air blast beak 5 in convergent-divergent pipe 4 aditus laryngis places links to each other with blower fan 10 by last connection airduct 11.During blower fan 10 work, a part of air-flow sprays from the series inclination air nozzle 14 on the annular blast pipe 15, forms conical air curtain 1, enters convergent-divergent pipe 4 and form negative pressure in aditus laryngis place flow at high speed under the guiding of oil-collecting petticoat pipe assembly 3; Another part air-flow sprays at a high speed from aditus laryngis air blast beak 5 and also forms negative pressure.Be enclosed in the oil smoke 2 in the conical air curtain 1, under the acting in conjunction of flow air curtain drainage and the dual negative pressure in aditus laryngis place, behind oil-collecting petticoat pipe assembly 3, be mixed into oil smoke air-flow 6 with air-flow in convergent-divergent pipe 4, oil smoke air-flow 6 is discharged at the mouth of pipe 9 places of oil extraction smoke pipe 8.
