Description
Technical field
A kind of range hood is the utility model is related to, 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
Caused oil smoke in 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 that occupying little space, and it is in an increasingly wide range of applications.
Traditional top-sucking kitchen ventilator generally includes exhaust fume collecting hood, the blower housing on exhaust fume collecting hood, in blower housing
Centrifugal blower is installed.A kind of range hood as disclosed in the Chinese patent of Application No. 201310111282.8, including for
Smoke collecting chamber, the flow-guiding channel connected with smoke collecting chamber of oil smoke are collapsed, 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 are 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 among range hood, and smoke collecting chamber physically shrouds oil
Cigarette, oil smoke is concentrated to be aspirated from the air inlet of centre.Because oil smoke produces out of pot, during ascension, spread up and out, i.e.,
More up, shape, area are bigger, produce similar mushroom shaped, because negative pressure region is limited caused by lampblack absorber, so in outer
The oil smoke enclosed, it is easy to produce escape.
The range hood of existing several different structures 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, catchment cup is provided with below smoke deflector side, air intake is provided with exhaust fume collecting hood
Mouthful, the smoke deflector face air inlet sets and maintains predetermined spacing with exhaust fume collecting hood, so as in smoke deflector and both exhaust fume collecting hoods
Between formed with holding the oil smoke passage that passes through of oil smoke.
Above-mentioned this range hood, its set the purpose of smoke deflector be in order to which the region of air intake is expanded, from four sides air intake,
But after setting smoke deflector, main air blower import still in centre, thus causes to have a disadvantage that：1st, wind enters from smoke deflector gap
Afterwards, to increase by two right-angled bends, cause damage bigger；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 longitudinal air inlet is formed, and longitudinal air inlet can be advantageous to concentrate downwards 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 as to which fume-exhausting is imitated
Fruit is more preferable.
The range hood of another structure, it is on the basis of opening up air inlet in centre, is set in the outside of exhaust fume collecting hood auxiliary
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 are mounted in cabinet lower end built with blower fan, exhaust fume collecting hood inner housing, and exhaust fume collecting hood, which covers, 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 secondary air inlet is disposed with along side plate in the upper curved side plate of exhaust fume collecting hood.
Because flow pressure is certain caused by main air blower, 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.
Utility model content
Technical problem to be solved in the utility model is in view of the above-mentioned problems of the prior art, providing a kind of lifting
The shunting range hood of range hood.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of shunting range hood, including
Exhaust fume collecting hood and the fan shroud above exhaust fume collecting hood, centrifugal blower are provided with the fan shroud, the exhaust fume collecting hood includes inner casing
Body, the inner housing include multiple side plates, it is characterised in that：The inner housing also includes the top plate for being connected to each side plate top,
Space below each side plate interior sides and top plate of the inner housing forms concave up smoke collecting chamber, the inner housing it is at least one
Air admission hole is offered on side plate, 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.
Preferably, 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 advantageous to concentrate 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 as to smoke absorption effect it is more preferable.
The angle of inclination of each side plate is 0 °~90 °.
Preferably, 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 flowed 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 include multiple side plates,
Each side plate top of the shell body is higher than each side plate top of inner housing, each side of each side plate and fan shroud of the shell body
Wall connects, 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, the first air inlet of the centrifugal blower is facing forward, and the second air inlet of the centrifugal blower is backwards.
Compared with prior art, the utility model has the advantage of：Designed by structure and air flow field, by range hood
Oil smoke import by lampblack absorber center, left and right is shifted forwards, backwards, all around drive stomata on four inclined-planes in smoke collecting chamber, and seal
The import of centre is closed, to match oil smoke during upward ascension, similar mushroom shape is produced, absorbs oil in four direction
Cigarette, so as to lift smoke absorption effect, prevent fumes escaping.
