Description
Technical field
The present invention relates to a kind of exhauster for removing kitchen fumes, the nearly kitchen hood of more particularly to a kind of household kitchen.
Background technology
Household kitchen lampblack absorber is Modern Family, and special for being the essential cooking apparatus of Chinese meal meals family, it passes through
The mode of pump drainage and fume purifying, by kitchen fume except oil purification heel row goes out to outdoor, purify indoor environment.Range hood structure shape
Formula is more, including the European top range hood originating from Europe, and the side developed by compatriots is inhaled, the lower nearly range hood of air draught class
Deng.European-style range hood is because above cooking stove, exhaust fume collecting hood has larger distance from pollution sources, and during its work, blower fan produces
Negative pressure the cleaned air around exhaust fume collecting hood also pump drainage is gone out, in the case where discharge capacity is limited, reduces fume exhaust and give up
The efficiency of gas.In addition, its clarifier uses multistorey strainer mesh structure more, its filter screen is limited to fume purifying effect, not easy to clean, and
Noise is big.Side is inhaled and lower range hood suction efficiency is higher, and fume purifying effect is limited, and easy cleaning, noise be not larger, and because of tool
Cooking stove is nearer, and air-flow reduces stove thermal efficiency, and common problem is shutdown window of being turned on the aircondition in winter and summer kitchen room
When, interior does not have air inlet, and air pressure changes, and oil flue waste gas is difficult to exclude.For this reason, it may be necessary to provide a kind of oil of brand new
Cigarette machine, to improve fume exhaust waste gas efficiency, fume purifying rate is improved, reduce noise, it is easy to clean, stove thermal efficiency is influenceed
It is small, energy-conservation, the fume exhaust effect that can have also had when summer in winter closes the doors and windows.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, there is provided a kind of nearly kitchen hood, with improve suction efficiency,
Fume pollution is reduced, reduces noise, it is ensured that stove thermal efficiency；And further solves room pressure equilibrium problem.
To realize object defined above, the present invention adopts the following technical scheme that.
A kind of nearly kitchen hood, including the cigarette hood for being horizontally set on above cooking stove, it is connected with cigarette hood and takes out
Inspiration wind pipeline and smoke discharging pipe, suction intake stack is interior to be provided with oil fume purifier, and smoke discharging pipe is connected with blower fan, the suction
Intake stack rectangular in cross-section, and after being extended downwardly by the cigarette hood posterior vertical, horizontally outward extension forms L-shaped, aspirates
The oil smoke air inlet of intake stack is set by pancake horizontal direction air intake, aspirate the oil smoke air outlet of intake stack with it is described
The inlet scoop connection that blower fan is provided with.
Using the present invention of preceding solution, by aspirating horizontal-extending section of intake stack, make its smoke inlet, be located at
Above cooking stove and cooker, closer to hot gas, the cooker of oil smoke source of generation, kitchen range, to improve suction effect；It is and flat
Strip oil smoke air inlet high velocity air as caused by negative pressure forms protected type air curtain on the top of cooking stove cooker, prevents oil smoke
Sucked while the diffusion of waste gas, discharge outdoor after purified, improve pumping efficiency；Meanwhile shielding air curtain makes suction
Air-flow be limited in the top of cooker, effectively reduce the influence to kitchen range firepower, it is ensured that the kitchen range thermal efficiency.By downward
The rectangular cross section suction intake stack of extension, and by the lower port air intake of pipeline, the oil smoke that can effectively extend oil fume purifier is net
Change passage, and make blower fan of the suction intake stack away from noise source of generation, so as to effectively reduce noise, improve clean-up effect.
Preferably, the oil smoke air inlet stretches out with close to the height and length at the top of cooker, and section is in level
Left and right directions has the width that can cover whole cooking stove and cooker fume pollution sources.Further ensure that barrier air curtain is formed, carry
High pumping efficiency.
Preferably, the oil fume purifier includes the purification housing of rectangle core structure, and purification enclosure interior passes through several
What is be set up in parallel is separated into multiple fume purifying passages in continuous S shapes or the corrugated dividing plate of polyline shaped.So that into passage
Oil smoke gaseous mixture the collision repeatedly turned back is formed on the purifying paths of complications, separate mist of oil and steam, it is ensured that purification effect
Fruit, and the greasy dirt for making to condense on fan blade or impeller greatly reduces；Meanwhile noise caused by blower fan along pipeline from top to bottom by
In outwards propagate, sound wave is decayed when by oil fume purifier tortuous filter disc, realizes decrease of noise functions again repeatedly.It is and net
Change channel cross-section is big, and windage is small, is easy to wipe when can effectively drop low wind noise, and clean, easy to clean.
Preferably, the cigarette hood is rectangular, is additionally provided with cigarette hood for extraneous and ambient air fresh air channel.
To supplement fresh air into kitchen room by fresh air channel, room pressure is maintained, pump drainage load is reduced, not only contributes to reduce
Noise, it can also improve pump drainage efficiency and effect.
It is further preferred that the fresh air channel includes fresh air airduct, the air inlet of fresh air airduct is located outside, fresh air wind
The air outlet of pipe connects with the cigarette hood inner chamber of ghost type；Tripartite's rectangle frame air outlet is offered on cigarette hood bottom surface.With from
Tripartite above cooker supplements fresh air, further improves oil fume pump exhaust effect.Meanwhile fresh air air outlet is closer and is located at
It is nearer from oil smoke air inlet above air curtain barrier, it can effectively reduce indoor not being mixed into the pure airs such as oil smoke, hot gas and be pumped
Discharge, it accordingly can ensure that the indoor air by air-conditioning holding constant temperature is not pumped, reduce air conditioner energy loss.In addition, cigarette machine
Cover is only used for new wind part and whole machine installation basis, and the size that it stretches out is smaller, effectively reduces the probability collided on head.
Preferably, the air outlet is made up of rows of bar hole.So as to directly by punch process mode directly in cigarette
Formed on hood, reduce difficulty of processing and manufacturing cost；Cigarette hood intensity can be also improved, further reduces noise.
It is further preferred that the cigarette hood bottom surface is in concave shaped structure, and on the outside of the frame side positioned at the air outlet
Formed with guide face.When lampblack absorber pump drainage component not to work, the hot gas of rising to be guided to fresh air by guide face and led to
In road, outdoor, formation nature pump drainage effect is then excluded.In the case of only having hot gas and water smoke, power consumption can be saved.
Preferably, plug-in type swab case, aspirate intake stack horizontal-extending section are provided with below the suction intake stack
Lower wall is provided with oil leakaging port.To ensure the collection of waste oil and focus on, it is ensured that clean and easy to use.
The invention has the advantages that oil fume pump exhaust efficiency high, good purification, noise are low, the kitchen range thermal efficiency is high, and tie
Structure is simple, use and cleaning are convenient.
