Abstract
The invention discloses a smoke exhaust pipe for an extractor hood. The smoke exhaust pipe comprises a hollow pipe, and is characterized in that the inner wall of the hollow pipe is a smooth face without folds, and an oil collecting hole and an oil collecting box used for collecting condensation oil drops are formed in the bottom of the hollow pipe. By means of the smoke exhaust pipe, lampblack obtained after condensation separation can be collected, formation and accumulation of oil dirt in the smoke exhaust pipe are avoided, and the smoke exhaust pipe is safer and more environment-friendly; and meanwhile, local resistance inside an air inducing channel is effectively reduced, and the air inducing amount and the wind pressure resistance are improved.
Description
Technical field
The present invention relates to range hood technical field, more particularly to a kind of smoke evacuation used for range hood for collecting separation oil smoke
Pipe.
Background technology
Smoke exhaust pipe is a kind of conventional pipeline for connecting range hood and common flue.At present, the common fume-exhausting of in the market
Machine smoke exhaust pipe is corrugated, is made up of telescopic aluminium foil or plastics.In long-term practical studies find, it is existing this
Plant smoke exhaust pipe and be primarily present following two big shortcomings：1) after long-time use, smoke exhaust pipe internal droplets accumulate to form grease, it is difficult to clear
, there is the potential safety hazard such as carcinogenic, inflammable in reason.2) corrugated flue structure is also easy to produce air whirl, office at wedge angle 01, wedge angle 02
Portion's resistance is big, causes air quantity to be restricted, and influences smoke exhaust efficiency, as shown in Figure 3.
The content of the invention
For problems of the prior art, it is an object of the invention to propose that a kind of smoke evacuation resistance is small, will can condense
Oil droplet smoothly derive, avoid oil droplet from accumulating the smoke exhaust pipe used for range hood to form grease.
To achieve the above objectives, the present invention is adopted the following technical scheme that.
A kind of smoke exhaust pipe used for range hood, including hollow tube, it is characterised in that the inwall of the hollow tube is aptychus
The even surface of wrinkle, is provided with oil collecting hole and the oil collection box of oil droplet is condensed for collecting in the bottom of hollow tube.
Used as with improvement, the oil collection box is connected by I-shaped drawing and pulling type slideway with smoke pipe.
As with improvement, oil guide groove is provided with the bottom of hollow tube, the oil collecting hole is opened in one end of oil guide groove.
Used as with improvement, the oil guide groove is bar-shaped trough, and the two ends of bar-shaped trough are located at the smoke inlet of smoke exhaust pipe and go out respectively
Mouth.
As with improvement, the first joint and the second joint are respectively equipped with the smoke inlet and outlet flue of smoke exhaust pipe, first connects
Head, the opening of the second joint are all inclined upwardly, and the second joint is higher than the first joint.
Used as with improvement, the aperture area of the aperture area more than the second joint of first joint, the smoke exhaust pipe is horizontal
Area of section connects between the aperture area of the first joint and the aperture area of the second joint and from the first joint to second
Descending gradual change successively at head.
As with improvement, the big 10%-15% of aperture area of the joint of open area ratio second of the first joint.
Used as with improvement, the smoke exhaust pipe can freely be stretched or shunk.
Used as with improvement, the smoke exhaust pipe is made up of aluminium foil, to ensure that smoke exhaust pipe can be received freely in the case of corrugationless
Hold together, stretch.
The beneficial effects of the invention are as follows：
First, by setting oil collecting hole and oil collection box, smoke pipe condensation oil smoke is collected, it is to avoid grease shape inside smoke pipe
Into, pile up, safer environmental protection, extend smoke pipe service life；Meanwhile, hollow tube inwall is smooth structure, effectively reduces air inducing
Local resistance in passage, improves absorbing quantity, discharges fume smooth, it is ensured that cigarette machine smoke discharging effect.
2nd, because the aperture area of the first joint connects more than the aperture area and the second joint of the second joint higher than first
Head, can effective range hood resisting wind press capacity.

Specific embodiment
Essence of the invention is more fully understood for convenience of those skilled in the art, below in conjunction with the accompanying drawings to of the invention specific
Implementation method is described in detail.
As shown in Figure 1 and Figure 2, a kind of smoke exhaust pipe used for range hood, including hollow tube 1, it is characterised in that described hollow
The inwall of body 1 is the even surface of corrugationless, and oil collecting hole 2 is provided with and for collecting condensation oil droplet in the bottom of hollow tube 1
Oil collection box 3.
Wherein, the smoke exhaust pipe is made up of aluminum foil material, with ensure smoke exhaust pipe can freely be drawn in the case of corrugationless,
Stretching.Oil guide groove 4 is provided with the bottom of hollow tube 1, the oil collecting hole 2 is opened in one end of oil guide groove 4.The oil collection box 3
It is connected with smoke pipe by I-shaped drawing and pulling type slideway.
In the present embodiment, preferably oil guide groove 4 is bar-shaped trough, the two ends of bar-shaped trough 4 respectively positioned at smoke exhaust pipe smoke inlet and
Outlet flue.The first joint 5 and the second joint 6 are respectively equipped with the smoke inlet and outlet flue of smoke exhaust pipe, the first joint 5, second connect
First 6 opening is all inclined upwardly, and the second joint 6 is higher than the first joint 5.So, it is in incline when whole smoke exhaust pipe is stretched to launch
It is ramp-like, it is easy to condense the collection of oil droplet.It is preferred that chute corresponding with I-shaped drawing and pulling type slideway is provided with the first joint 5, just
In the installation of oil collection box 3.
Further, the aperture area of first joint 5 is more than the aperture area of the second joint 6, and the smoke exhaust pipe is horizontal
Area of section is between the aperture area of the first joint 5 and the aperture area of the second joint 6 and from the first joint 5 to
Descending gradual change successively at two joints 6.So, the Wind-Pressure Resistance effect of range hood smoke evacuation can be effectively improved.
Experiment proves that, as the big 10%-15% of aperture area of second joint of open area ratio 6 of the first joint 5, oil suction
The smoke evacuation of cigarette machine is the most smooth, and whole fan delivery is per minute about to improve 0.5 cubic metre, and smoke orifice blast about improves 10Pa or so, resists
Blast effect is protruded.
Above specific embodiment has been described in detail to essence of the invention, but can not be come to of the invention with this
Protection domain is limited.It should be evident that under the enlightenment of essence of the invention, the art those of ordinary skill can also enter
The many improvement of row and modification, it should be noted that these improve and modification all fall claims of the invention it
It is interior.
