Description
Technical field
The present invention relates to fume purifier of fume, the control methods of especially a kind of range hood and the range hood.
Background technique
Currently, common range hood includes top suction type, side-suction type and descending in the market, top-sucking kitchen ventilator is using oil
Cigarette ascension principle generates negative pressuren zone in the surface of hearth, the oil smoke risen naturally that suction generates when cooking, its advantage is that outside
See that fashion is succinct, air quantity is larger, it is larger to be suitable for space, can the farther away oil smoke of lock-on range hearth, the disadvantage is that mounting height
Farther out from hearth, under small oil smoke amount cooking status, the disturbance that the oil smoke above pot is generated vulnerable to surrounding air causes oil smoke
It escapes around, causes smoke absorption effect poor.The range hood power source of side-suction type is closer from hearth, will be largely apart from stove
The closer oil smoke of platform is absorbed with form of arcs, its advantage is that fuselage is thin, operation is not easy to meet and discuss, under small oil smoke amount cooking status,
Since its mounting height is lower, negative pressuren zone is closer apart from cigarette source, and smoke absorption effect is good, the disadvantage is that in the culinary art of big oil smoke amount, top
Under the states such as spoon, since mounting height is lower, the oil smoke for causing escape to rise can not be inhaled into discharge.The sucking of descending kitchen ventilator
Mouth is closer apart from hearth, and close to cigarette source, the path of oil smoke movement reduces negative pressuren zone, compared with other two kinds of forms, fume-exhausting
Effect is preferable, but has the following problems, under the big oil smoke state such as quick-fried, oil smoke is easily escaped around.Single pot of gas-cooker is cooked
When preparing food, negative pressuren zone is not concentrated, and smoke absorption effect is poor.
The characteristics of in order to make full use of each form range hood, also there has been some schemes for various forms of oil suctions at present
Smoke machine combines.Such as application No. is 201320250895.5 Chinese patent, application No. is the Chinese patent of 201610588598.X,
A kind of kitchen ventilator that top side suction combines all is disclosed, under small oil smoke amount cooking status, top smoking port is also at open shape
State, this will cause the reduction of bottom end suction inlet negative pressuren zone, and effective wind rate reduces, and smoke absorption effect is deteriorated.For another example application No. is
201320124231.4 Chinese patent discloses one kind three and enters the wind roof range hood, in small oil smoke amount, single pot of cooking status
Under, since air inlet of kitchen ventilator is more, inlet flow road length, single suction inlet negative pressuren zone is small, and effective wind rate reduces, smoke absorption effect
It is poor.
