Description
Technical field
The present invention relates to kitchen tools product, the range hood automatically cleaning more particularly to a kind of water curtain style.
Background technology
Range hood is a kind of conventional home kitchen appliance, and it can be the oil smoke producing in gastronomical process in kitchen and water
Vapour is drawn into outdoor, thus reaching the purpose purifying kitchen environment.But, range hood work during, table in housing
Face and impeller all can adhere to and deposit greasy dirt dirt, if cleaning will become to be very difficult to remove not in time, but also can affect to inhale
The dynamic balancing of the impeller of lampblack absorber, thus affect the suction capactity of range hood.
Patent Office of the People's Republic of China disclose on March 16th, 2011 Patent No. ZL2009100992858 " one kind can oil smoke separate
Range hood ", this technical scheme is range hood smoke deflector rear end bending, casing relative with range hood water reserve downwards
Water reserve in the distance between the water surface and smoke deflector bottom be 30-100 millimeter.Offer below the water reserve of casing and enter
Water inlet and the outlet being connected with outlet pipe that water pipe is connected.During the work of this technical scheme, negative by formed in casing
Pressure, so that part water is up altered in the presence of negative pressure so that oil smoke and water condensation by mixing again, ultimately forms oil water mixture and drops to
The water reserve of casing, accomplishes that oil smoke separates, and environmental protection also can reduce casing inner wall and impeller long-pending oil.This kind of range hood exist with
Lower defect：
1st, due to being provided only with water inlet and outlet in the casing of this range hood, water reserve need to intake by tap water,
Therefore, family uses such range hood must preset one near the position installing range hood certainly in house decoration
Carry out water pipe outlet, but general family is all just to go to purchase range hood, therefore to range hood after laying water pipe
Using bringing obstacle.
Although the 2, this range hood has the detached effect of oil smoke, but cannot accomplish that oil smoke very separates, machine
Still understand dirt deposits on shell inwall and impeller, and this range hood cannot accomplish the effect automatically cleaned.
Content of the invention
The technical problem to be solved in the present invention is to provide the range hood that a kind of water curtain style cleans automatically, this range hood
Carry water feed apparatus, installation need not lay water supply pipe, install more convenient, but also enable the effect automatically cleaned.
The technical solution of the present invention is to provide the fume-exhausting that a kind of water curtain style with following structure cleans automatically
Machine, including casing and blower fan, described blower fan is in described casing；Described casing is provided with air inlet；Described machine
