Description
Technical field
The present invention relates to kitchen tools product, relate to the range hood that a kind of water curtain style cleans automatically or rather.
Background technology
Range hood is a kind of conventional home kitchen appliance, and it can be drawn into outdoor the oil smoke produced in gastronomical process in kitchen and steam, thus reaches the object of purification kitchen environment.But, range hood is in the process of work, and shell inner surface and impeller all can adhere to and deposit greasy dirt dirt, will become be very difficult to remove if clean not in time, but also the dynamic balancing of the impeller of range hood can be affected, thus affect the suction capactity of range hood.
Patent Office of the People's Republic of China disclose on March 16th, 2011 patent No. be ZL2009100992858 " a kind of can oil smoke be separated range hood ", this technical scheme is that range hood smoke deflector rear end bends downwards and relative with range hood water reserve, and the distance between bottom the water surface in the water reserve of casing and smoke deflector is 30-100 millimeter.The delivery port offering the water inlet be connected with water inlet pipe below the water reserve of casing and be connected with outlet pipe.During the work of this technical scheme, by the negative pressure formed in casing, up alter under making the effect of part water negative pressure again, make oil smoke and water condensation by mixing, final formation oil water mixture drops to the water reserve of casing, accomplishes that oil smoke is separated, environmental protection, also can reduce casing inner wall and the long-pending oil of impeller.There is following defect in this kind of range hood:
1, due to the casing of this range hood being only provided with water inlet and delivery port, water reserve need intake by running water, therefore, family uses this kind of range hood must when house decoration, a running water pipe delivery port is preset near the position of installing range hood, but general family just goes to purchase range hood after laying water pipe, therefore brings obstacle to the use of range hood.
Although 2, this range hood has the effect that oil smoke is separated, but cannot accomplish that oil smoke is very separated, can dirt deposits on casing inner wall and impeller, and this range hood cannot accomplish the effect of automatically cleaning.
Summary of the invention
The technical problem to be solved in the present invention is, provides the range hood that a kind of water curtain style cleans automatically, and this range hood carries water feed apparatus, installs without the need to laying water supply pipe, installs more convenient, and can also realize the effect of cleaning automatically.
Technical solution of the present invention is, the range hood providing a kind of water curtain style with following structure automatically to clean, comprises casing and blower fan, and described blower fan is located in described casing; Described casing is provided with air inlet; Smoke deflector is provided with and this smoke deflector is located at the rear side of described air inlet in described casing; The bottom of described casing is provided with water reserve and this water reserve is positioned at the below of described smoke deflector; Described casing is provided with water inlet and delivery port, the water feed apparatus of described range hood also with the water inlet of oriented water reserve; The water surface in described water reserve and the distance between smoke deflector extreme lower position are for being more than or equal to zero and being less than 30 millimeters.
