Description
Technical field
The invention belongs to the improvement of cooking fume exhausting device structure, particularly fire safety smoke exhaust ventilator.
Background technology
Although various existing cooking fume exhausting devices are gradually improved, and cooking fume exhausting works well, but oil smoke is by suction
During still can stick to the tradition such as motor and be arranged to be formed on the electromechanical component in cooking fume exhausting device exhaust fume collecting hood and be difficult to
The grease being eliminated, additionally, generally, the frying pan below exhaust fume collecting hood edible oil when catching fire its flame it is upward
Pour in exhaust fume collecting hood cover chamber and scaling loss cooking fume exhausting device, or even cause fire.So, existing cooking fume exhausting apparatus structure is excessively
Complicated, unreasonable, grease removes maintenance work amount greatly, fire resisting（Fire prevention）Aberrations in property.
The content of the invention
It is simple and reasonable for structure it is an object of the invention to provide a kind of fire safety smoke exhaust ventilator, grease is greatly reduced clear
Except maintenance work amount, fire safety performance is significantly improved.
The object of the present invention is achieved like this：A kind of fire safety smoke exhaust ventilator, including it is the bunched cover of taper oil smoke, electronic
Machine, power transmission shaft and flabellum, taper oil smoke is bunched cover the big opening that offers of its bottom formed down oil smoke influent stream cover mouthful and
Its topmost offer small opening up less than oil smoke influent stream cover mouthful and form oil smoke and go out to flow cover mouth so that taper oil smoke collection
Hold together cover to be set with positive cone shape state, the fire resisting fire-proof plate being fixedly mounted with the bunched cover of taper oil smoke is by the bunched cover cover chamber of taper oil smoke
The back-fire relief negative pressure cover chamber being divided into below fire resisting fire-proof plate and the cooking fume exhausting negative pressure cover chamber above fire resisting fire-proof plate,
Fire resisting fire-proof plate is offered and penetrates its own plate body and uniform flue gas mistake on its own plate body along itself plate body thickness direction
Drift net hole, goes out to flow to be fixedly mounted with cover mouth the oil smoke interconnected with cooking fume exhausting negative pressure cover chamber and goes out flow cartridge in oil smoke, and oil smoke goes out stream
One end nozzle of cylinder goes out to flow the cooperation of cover mouth static seal with oil smoke, goes out in oil smoke and suspension is fixedly mounted with flow cartridge, is fixedly mounted with suspension
Protection machine box, the part bar segment that suspension itself has respectively with through protection machine box be located at its bottom shell wall and the top shell wall it
Between middle part shell wall be provided with first perforation through protection machine box middle part shell wall mode and protection machine box be mutually packed in one
Rise, suspension is all to pass through the bar segment of the first perforation to coordinate with the first perforation static seal, and suspension is located at the bar in protection machine box box chamber
Section is provided with relative set in clutch shaft bearing and second bearing in protection machine box box chamber, and power transmission shaft being erected to through protection substantially
The second perforation that machine box bottom shell wall is provided with is through protection machine box bottom shell wall and through clutch shaft bearing and second bearing
Mode be suspended on suspension by clutch shaft bearing and second bearing simultaneously, power transmission shaft is perforated with second in the way of rotation and moves close
Envelope coordinates, and power transmission shaft upper end is located in protection machine box box chamber and is fixed with relative set in the first cone tooth in protection machine box box chamber
Wheel, power transmission shaft lower end is located in cooking fume exhausting negative pressure cover chamber and is fixed with relative set and is transmitted in cooking fume exhausting negative pressure cover chamber
Axle hangs succeeds and hanging flabellum in back-fire relief negative pressure cover chamber, and flabellum can be born from oil smoke influent stream cover mouthful in rotation into back-fire relief
Press flue gas excessively stream mesh, cooking fume exhausting negative pressure cover chamber that the oil-contg. smoke body of cover chamber is laid with through fire resisting fire-proof plate successively upwards with
Oil smoke goes out to flow cover mouth, oil smoke and goes out flow cartridge barrel chamber to drain to outside the bunched cover of taper oil smoke, goes out what flow cartridge perisporium was provided with oil smoke
3rd bearing is installed, motor goes out location and installation in the way of flow cartridge is fixed and goes out flow cartridge in oil smoke by relative oil smoke in the 3rd perforation
Outside, the middle part shell wall that protection machine box is located between its bottom shell wall and the top shell wall is additionally provided with the 4th perforation, electronic
The output revolving shaft of machine is located at the power output shaft part outside its casing essentially horizontally to be perforated through 3rd bearing, oil through the 3rd
Cigarette goes out flow cartridge perisporium and goes out flow cartridge phase by 3rd bearing and oil smoke through the mode of protection machine box middle part shell wall through the 4th perforation
Mutually it is installed together, power output shaft part is coordinated in the way of rotation with the 4th perforation dynamic sealing, and power output shaft part is placed on
One end outside motor casing is located in protection machine box box chamber and is fixed with relative set in second in protection machine box box chamber
Bevel gear, second bevel gear is intermeshed with first bevel gear.
During present invention work, fire resisting fire-proof plate can substantially prevent the flame altered to back-fire relief negative pressure cover chamber upwards from entering oil smoke
Suction negative pressure cover chamber, at the same time, because of culinary art, the part oil smoke from frying pan generation and the air near oil smoke can then be passed through successively
Flue gas excessively stream mesh, cooking fume exhausting negative pressure cover chamber and the oil smoke that back-fire relief negative pressure cover chamber, fire resisting fire-proof plate are laid with go out to flow cover mouth, oil
Cigarette goes out flow cartridge barrel chamber and is drained to upwards by flabellum outside the bunched cover of taper oil smoke（It is outdoor）, hermetically sealed protection machine box make suspension position
Bar segment in its box chamber with bevel gear and outside protection machine box mutually come and motor is placed on taper completely by isolation
Outside the bunched cover of oil smoke, another part residue oil smoke only can adhere to the bunched cover of taper oil smoke, fan during by upward drainage
Leaf, protection machine box outer surfac, oil smoke go out the bar segment of flow cartridge inner surface, suspension outside protection machine box etc. and are built in protection machine box
The object relatively simple with the structure that the space between the bunched cover of taper oil smoke and oil smoke go out in flow cartridge, so, protection machine box can
Prevent oil smoke from entering inside it, with the part for keeping being entirely located in protection machine box box chamber（Such as bevel gear）With part part position
In the site anteseptic in protection machine box box chamber without grease, pollution-free.The present invention is simple and reasonable for structure, and grease removing is greatly reduced
Maintenance work amount（If it is detachable, energy and the cost of its take-down time and cleaning can be reduced further）, fire resisting peace
Full performance is significantly improved.
