Description
Technical field
The present invention relates to a kind of range hood, especially a kind of shunting range hood.
Background technology
Range hood turns into one of machine for kitchen use equipment indispensable in Modern Family, is cooked for discharging cooking stove
Oil smoke produced by journey.Usual range hood includes top suction type and side-suction type, and the range hood of top suction type is due to clean and tidy light
Ingeniously, the advantages of occupying little space, and it is in an increasingly wide range of applications.
Traditional top-sucking kitchen ventilator is generally included in exhaust fume collecting hood, the blower housing on exhaust fume collecting hood, blower housing
Centrifugal blower is installed.A kind of range hood as disclosed in the Chinese patent of Application No. 201310111282.8, including for
The smoke collecting chamber for drawing oil smoke in, the flow-guiding channel connected with smoke collecting chamber, and for collecting the lubricating cup of greasy dirt, the bottom of smoke collecting chamber is
Smoke collecting chamber air inlet, the top of smoke collecting chamber is provided with smoke collecting chamber air outlet, and flow-guiding channel is arranged on above smoke collecting chamber air outlet.
Above-mentioned this range hood, is that air inlet is opened in the middle of range hood, and smoke collecting chamber physically shrouds oil
Cigarette, oil smoke is concentrated to be aspirated from middle air inlet.Produced due to oil smoke, during ascension, spread up and out, i.e., out of pot
More up, shape, area are bigger, produce similar mushroom shaped, because the negative pressure region that lampblack absorber is produced is limited, so in outer
The oil smoke enclosed, it is easy to produce escape.
The range hood of several different structures is had at present, to prevent the upward elegant oil smoke being diffused into outside exhaust fume collecting hood both sides
Escaped to external diffusion.A kind of one of which structure lampblack absorber as disclosed in the Chinese patent of Application No. 201620098707.5,
Including lampblack absorber body, exhaust fume collecting hood and smoke deflector, it is provided with below smoke deflector side in catchment cup, exhaust fume collecting hood and is provided with air intake
Mouthful, smoke deflector just sets to the air inlet and maintains predetermined spacing with exhaust fume collecting hood, so that in smoke deflector and both exhaust fume collecting hoods
Between be formed with and hold the oil smoke passage that passes through of oil smoke.
Above-mentioned this range hood, its set smoke deflector purpose be in order to by the region of air intake expand, from four sides air intake,
But set after smoke deflector, thus main air blower import causes to have a disadvantage that still in centre：1st, wind enters from smoke deflector gap
Afterwards, to increase by two right-angled bends, cause damage than larger；2nd, the gap that smoke deflector and smoke collecting chamber are combined into is air inlet, only
Horizontal cross gap can be formed, it is impossible to form longitudinal air inlet, and longitudinal air inlet can be conducive to concentrating downward with negative pressure region
Extension, longitudinal air intake can form a progressive barometric gradient in vertical direction, and negative pressure region is more concentrated, so that fume-exhausting is imitated
Fruit is more preferably.
The range hood of another structure, is on the basis of opening up air inlet in centre, to set auxiliary in the outside of exhaust fume collecting hood
The air inlet helped, a kind of exhaust fume collecting hood has the oil suction of air inlet concave chamber as disclosed in the Chinese patent of Application No. 200520051483.4
Cigarette machine, cabinet is mounted in cabinet lower end built with blower fan, exhaust fume collecting hood inner housing, and exhaust fume collecting hood, which is covered, to be packed at exhaust fume collecting hood inner housing,
Outer exhaust fume collecting hood lid has main air inlet cavity on exhaust fume collecting hood inner housing on the plate of exhaust fume collecting hood, in main air inlet cavity edge week
Wall cloth, which is put, is provided with main air inlet, and along side plate secondary air inlet is disposed with the upper curved side plate of exhaust fume collecting hood.
Because the flow pressure that main air blower is produced is certain, main air inlet is from blower fan closer to such pressure, flow concentrate on master
Air inlet region, four sides areal pressure, flow are few, and negative pressure region can not effectively spread, and smoke absorption effect is worse.
The content of the invention
The technical problems to be solved by the invention are in view of the above-mentioned problems of the prior art, providing a kind of lifting oil suction
The shunting range hood of cigarette machine.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：A kind of shunting range hood, including collection cigarette
Centrifugal blower is provided with cover and the fan shroud above exhaust fume collecting hood, the fan shroud, the exhaust fume collecting hood includes inner housing, institute
Stating inner housing includes multiple side plates, it is characterised in that：The inner housing also includes the top plate for being connected to each side plate top, described interior
Space below each side plate interior sides and top plate of housing is constituted on concave up smoke collecting chamber, at least one side plate of the inner housing
Air admission hole is offered, the air admission hole in fan shroud with connecting.
Optionally, the air admission hole extends in the lateral or vertical direction along respective side panels.
It is preferred that, each side plate is from the bottom to top gradually to intermediate, inclined, and the air admission hole is in the vertical with same with respective side panels
The angle of inclination extension of sample, longitudinal air inlet, which can be conducive to concentrating with negative pressure region, to be extended downwardly, and longitudinal air intake is in vertical direction
On can form a progressive barometric gradient, negative pressure region is more concentrated, so that smoke absorption effect is more preferable.
The angle of inclination of each side plate is 0 °~90 °.
It is preferred that, the air admission hole is strip, circle, rectangle or hexagon, and thus, air admission hole can coordinate blower fan
Energy, bevel angle, area etc., according to the requirement in flow field, convenient adjustment width, length, more reasonably flow so as to form one
, improve smoke absorption effect.
For ease of guiding the oil smoke entered from air admission hole to enter in fan shroud, the exhaust fume collecting hood also includes compartment of terrain and arranged
Shell body in inner housing periphery, the bottom end closure between the shell body and inner housing, the shell body includes multiple side plates,
Each side plate top of the shell body is higher than each side plate top of inner housing, each side plate of the shell body and each side of fan shroud
Wall is connected, and the space between the inner housing and shell body forms oil smoke passage, and the oil smoke passage inside fan shroud with connecting.
To improve air intake behind range hood, and then whole smoke absorption effect is lifted, the centrifugal blower is double air intakes
Blower fan, forward, the second air inlet of the centrifugal blower is backwards for the first air inlet of the centrifugal blower.
Compared with prior art, the advantage of the invention is that：Designed by structure and air flow field, by the oil of range hood
By lampblack absorber center, left and right is shifted forwards, backwards for cigarette import, drives stomata on smoke collecting chamber all around four inclined-planes, and in closing
Between import, to match oil smoke during upward ascension, produce similar mushroom shape, oil smoke absorbed in four direction,
So as to lift smoke absorption effect, fumes escaping is prevented.
