Abstract
The utility model discloses a jet flow negative pressure condensation type oil-fume extractor, which comprises an air hood for gathering oil fume, wherein the upper portion of the air hood is fixedly provided with a box body which is integrally arranged with the air hood, the inner portion of the box body is provided with a motor and a fan which is linked with the motor, the bottom portion of the fan is fixedly connected with a sleeve, the inner portion of the sleeve is sleeved with a jet flow pipe, the other end of the sleeve is provided with a negative pressure air pipe, and a negative pressure tongue pipe is arranged in the negative pressure air pipe. When the jet flow negative pressure condensation type oil-fume extractor pumps oil fume, oil fume can be directly exhausted along a pipeline without passing through a blade, residual oil fume on the upper portion of the air hood is whirled away under the action of negative pressure during the exhaust process, furthermore, new cold air can enter during the exhaust process of air flow, thereby producing pressure in the box body, and playing the condensation role, leading the oil fume to condensate on the outer pipe wall of the jet flow pipe, not needing to remove the oil-fume extractor, not needing to clean inner devices of the box body, just needing to clean outer pipe walls, saving time and labor, being green, and protecting pollution.
Description
Technical field
The utility model relates to a kind of smoke exhaust of removing oil smoke, particularly a kind of jet flow negative pressure condensing smoke exhaust.
Background technology
Existing smoke exhaust just installs motor and fan additional in the inside of its casing, adopt motor to reverse to realize absorption function to fan housing below oil smoke, but the mode of this suction oil smoke, can be adsorbed on the blade of fan through in the box house at oil smoke, long-term accumulation, cause the fan work ability to reduce, need regularly it to be cleaned, cleaning process wastes time and energy.
The utility model content
The utility model is at the deficiencies in the prior art, provides a kind of and does not adsorb the jet flow negative pressure condensing smoke exhaust of fan blade at oil smoke when discharging casing.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of jet flow negative pressure condensing smoke exhaust, comprise the fan housing that is used to gather oil smoke, this fan housing upper fixed is equipped with it and is the casing of one, this box house be provided with motor and with the fan of this motor interlock, described fan bottom is connected with a sleeve, and this sleeve inner is set with a jet pipe; The other end of described sleeve is provided with the negative pressure airduct, is provided with negative pressure tongue pipe in this negative pressure airduct.
Compared with prior art, the utility model is when the suction oil smoke, without blade, oil smoke directly can be discharged along pipeline, and in the process of discharging, not only the remaining oil smoke with the fan housing top sweeps away under suction function, can also in the discharge process of air-flow, enter new cold air, not only in casing, produce pressure, and play the effect of condensation, make oil smoke condensation on the tube wall of the outer end of jet pipe, need not remove smoke exhaust need not clean the box house device, only need the cleaning outer pipe wall, time saving and energy saving, environmental protection.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to accompanying drawing 1-3, in the present embodiment, this jet flow negative pressure condensing smoke exhaust, comprise the fan housing 6 that is used to gather oil smoke, the upper fixed of this fan housing 6 is equipped with it and is the casing 3 of one, the inside of this casing 3 be provided with motor 2 and with the fan 1 of these motor 2 interlocks, the bottom of fan 1 is connected with a sleeve 4, motor 2 and fan 1 are arranged on sleeve 4 excircles.The internal sleeve of this sleeve 4 is equipped with a jet pipe 7, is positioned on the sleeve 4 on the tube wall of fan 1 bottom to have an air outlet 8, and this sleeve 4 also can be made ovalize according to actual needs.The other end of sleeve 4 is provided with negative pressure airduct 5, is provided with negative pressure tongue pipe 9 in this negative pressure airduct 5.The cross section of negative pressure tongue pipe 9 is inverted letter " L " shape, and its bottom is communicated with fan housing 6 tops.Negative pressure tongue pipe 9 is communicated with fan housing 6 by the tube wall of negative pressure airduct 5, the oil smoke at fan housing 6 tops can be aspirated in the lump and discharges like this.Sleeve 4 stretches out the position and casing 3 welding of casing 3, and the end of jet pipe 7 is " T " shape structure, end at sleeve 4 blocks, internal tubular is communicated with, and the sectional area of remaining jet pipe 7 is sleeve 4 sectional areas half, there is the space like this between the two, cold air is stopped within it.Casing 3 is an enclosed construction, guarantees its gas inside pressure.
Generally speaking, the diameter D of jet pipe 7
1Be 190-200mm; When sleeve 4 is pipe, its general diameter D
2Be 380-400mm, i.e. D
2=2D
1The diameter D of negative pressure airduct 5
3Be 140-150mm; Height difference H on the negative pressure tongue pipe 9 is 40-60mm.
Principle of the present utility model is: under the rotation of fan 1, form certain gas pressure intensity in the casing 3 of sealing, after oil smoke aspirated up, under pressure, enter along negative pressure airduct 5, meanwhile, can be through the air-flow of negative pressure tongue pipe 9 in its recess formation negative pressure, the remaining oil smoke at fan housing 6 tops is involved in negative pressure airduct 5 by this negative pressure like this, and air-flow is discharged through jet pipe 7 then.In the process that air-flow is discharged, extraneous cold air enters the space between sleeve 4 and the jet pipe 7, and cold air is 8 discharges along the gas outlet, under fan 1 effect, produce pressure continuously, oil smoke to jet pipe 7 inside plays condensation, it is coagulated on the tube wall of the outer end of jet pipe 7 rapidly, be convenient to cleaning.
