Description
Technical field
The present invention relates to range hood, relate to a kind of European type cooker hood oil network device or rather.
Background technology
Studies in China result shows, kitchen fumes, as the exclusive class pollution sources of China, affects increasingly significant to city atmospheric environment quality, particularly in recent years, along with the development of Chinese Urbanization's and the adjustment of industry result, catering industry is fast-developing, and the use amount of edible oil increases day by day.Cooking fume is the important sources of aerosols from major cities, have expert to propose content of organics in Chinese PM2.5 is high may be relevant with the particularity of Chinese tradition cooking culture.The toxicity of kitchen fume mainly contains: have genetoxic, immunotoxicity, lungs toxicity and potential carcinogenicity to matrix.Cooking fume pollutes and to the Health cost effect of human body is the indoor environment problem of significant.At present, the kitchen fumes in kitchen is displaced into outdoor by the range hood that adopts more.Range hood mainly utilizes the work of air negative pressure principle.Range hood is made up of blower fan system, control system, oil filtering system and shell.According to hydrodynamics, when there is pressure difference when between adjacent air, gas can flow.Therefore, when blower fan works, large quantity of air is discharged from casing internal, and lower air port place produces negative pressure, and under the only pressure effect of air around, the air in lower air port is pushed into exhaust outlet, and oil smoke is constantly discharged.
Range hood can be divided into European type cooker hood and side extraction cooking fume extractor.European type cooker hood is also top suction type lampblack absorber, and its oil network device is the top being positioned at stove.Oil network device many employings three-dimensional contouring of the European type cooker hood of prior art, oil network device is concave or convex structure.Oil network device is double-deck oil network device, is mutually stacked together with outer net by Intranet.Inside and outside network is respectively equipped with the multiple air inlets be parallel to each other longitudinally arranged, air inlet on this Inside and outside network longitudinally separates Heterogeneous Permutation mutually, can be there is the defect that air intake has some setbacks in this kind of oil network device, thus reduce suction, cause running oil smoke many, leak the situation of inhaling.In addition, the lubricating cup design of the European type cooker hood of prior art is attached in oil network, is generally arranged on the middle part of oil network device, owing to limitting by erection space, oil network volume is designed less than normal, and lubricating cup falls oily and wash number is frequent.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of European type cooker hood oil network device is provided, this European type cooker hood oil network device air intake is smooth and easy, do not affect the suction of range hood, avoid occurring running the phenomenon that oil smoke is many, leak suction, but also the design of lubricating cup volume can be strengthened, reduce lubricating cup oil and the number of times cleaned.
Technical solution of the present invention is, provides a kind of European type cooker hood oil network device with following structure, comprises outer oil network and interior oil network; Described interior oil network is located at the inner side of described outer oil network, and this interior oil network and outer oil network entirety form oil network body; Described outer oil network and interior oil network are equipped with multiple air inlet be parallel to each other; Described oil network body comprises main air inlet face and two side air intake actinal surfaces be connected with the both sides in main air inlet face respectively; Described main air inlet face tilt is arranged, and the angle that this main air inlet face and horizontal plane are formed is 5-85 °; Air inlet in the interior oil network in described main air inlet face is positioned at the top of the air inlet outside described main air inlet face in oil network; The side of the air inlet in the interior oil network in described main air inlet face is provided with wind deflector all obliquely; The angle that the plane of the interior oil network in described wind deflector and described main air inlet face is formed is 20 °-50 °.
After adopting above structure, a kind of European type cooker hood oil network device of the present invention, compared with prior art, has the following advantages:
Because the main air inlet face tilt of European type cooker hood oil network device of the present invention is arranged, the angle that main air inlet face and horizontal plane are formed is 5-85 °, uses for reference to slide to jump formula aircraft carrier angle of inclination design principle to carry out Oil Guide and oil dripping, and Oil Guide effect is better.Air inlet in the interior oil network in described main air inlet face is positioned at the top of the air inlet outside described main air inlet face in oil network, and the side of the air inlet in the interior oil network in described main air inlet face is provided with wind deflector all obliquely, the angle that the plane of the interior oil network in described wind deflector and described main air inlet face is formed is 20 °-50 °, it is the theory of mechanics according to worm and gear, the blower fan system of range hood turns clockwise from the work of air inlet impeller, according to right-hand man's rule, the helix using again screw rod launches the principle carrying out the straight line being inclination, the angle that the plane of oil network in wind deflector and described main air inlet face is formed is set to 20 °-50 °, air inlet air intake can be made more smooth and easy, do not affect the suction of range hood, avoid occurring running oil smoke many, leak the phenomenon of inhaling, also turbulent phenomenon can be reduced.In addition, the setting of main air inlet face tilt, by lubricating cup design at the rear side of range hood main body, can be connected with main body, can strengthen the design of lubricating cup volume, reduces lubricating cup oil and the number of times of cleaning, brings convenience to the users.
As a modification of the present invention, in the interior oil network in described main air inlet face the width of air inlet be greater than the width of the air inlet in the outer oil network in described main air inlet face.After adopting this kind of structure, the resistance of interior oil network to wind can be reduced, oil network body air intake can be made more smooth and easy.
Improve as another kind of the present invention, the angle that the interior oil network in described wind deflector and described main air inlet face is formed is 45 °.This kind is designed to optimum implementation.
Also have a kind of improvement as of the present invention, the air inlet in the interior oil network in described main air inlet face is located in the plane of described interior oil network; The width of described wind deflector is not more than the width of the air inlet of the interior oil network in described main air inlet face; The longitudinal projection of described wind deflector covers the air inlet in the outer oil network in corresponding main air inlet face.After adopting this kind of structure, wind deflector can be made by the mode of oil network in cutting, makes simple; The longitudinal projection of wind deflector covers the air inlet in the outer oil network in corresponding main air inlet face, makes the wind effect of wind deflector better.
Also have a kind of improvement as of the present invention, the width of described wind deflector is less than the width of the air inlet of the interior oil network in described main air inlet face.Adopt this kind of structure, make the wind effect of wind deflector better and choke effect can not be increased again, make air inlet air inlet effect better.
