Abstract
The utility model relates to a range hood member, in particular to a turbine assembly with one casing and three wind wheels for a range hood. Aiming to solve the problem that air dissipation dead-angles in the casing of the range hood influence air volume for oil absorption, the utility model provides the turbine assembly with one casing and three wind wheels for a range hood through improving the wind wheel structure. A large wind wheel is divided into two gaplessly independent wind wheels through a division board, so as to effectively improve the suction and exhaust air volume and oil fume purification effect, enhance the effect of reasonable oil fume suction and exhaust, ensure stable air volume and low running noise, and truly realize low carbon, energy conservation, environment friendliness, purification, and durability of the range hood.
Description
Technical field
The present invention relates to a kind of range hood member, particularly relate to a kind of monoshell three wind wheel turbine assemblies of range hood.
Background technology
Traditional used for range hood wind wheel is the fan blade circle that a circle is evenly installed at interval, and the air quantity that adopts such wind wheel structure to obtain is little, and the oil smoke absorbing effect is relatively poor, can't thoroughly absorb the oil smoke in the kitchen clean.The inventor designs respectively on the basis of traditional range hood and has researched and developed two wind wheels and four wind wheel range hoods; These two kinds of structures have been improved the air quantity of range hood to a great extent; Thereby effectively raise the oil smoke absorbing effect of range hood; But still have weak point in its structure, cause still to have the wind dead angle of loosing in the housing of range hood, oil smoke absorbing efficient can't further improve.
Summary of the invention
The present invention is directed to and have the wind dead angle of loosing in the range hood shell; Influence the problem of oil smoke absorbing air quantity; Through improving wind wheel structure; A kind of range hood monoshell three wind wheel turbine assemblies are provided, have comprised Scroll-type housing, are arranged at windowing of housing side face with an open end, said window for oil smoke import, open end be the oil smoke outlet; Also include the wind wheel that is used for oil smoke suction and purification in the said housing; Said wind wheel comprises big wind wheel and little wind wheel; Said big wind wheel and little wind wheel are the turning cylinder edge even blade spaced apart of circumference separately with the motor output shaft; Also include division board on the said big wind wheel, the division board vertical fixing is divided into big wind wheel the no gap wind wheel of two coaxial rotation between big wind wheel adjacent blades.Owing to set up partition plate structure on the big wind wheel, so be divided into two parts, the no gap wind wheel of two coaxial rotation about formation with big wind wheel is seamless; This wind wheel structure and air inlet and air outlet cooperatively interact, and form three-dimensional wind-force, thereby have overcome the problem of wind-force scattering in the conventional wind wheel structure; Make wind direction same; Wind-force is even, thereby has increased the range hood exhaust air rate, has improved range hood efficient.
Optimal way as a kind of isolation; The invention discloses said division board separates the ratio of big wind wheel blade according to 1:3; Thereby help discharging the diffusing wind at procapsid dead angle via the wind wheel that passage 1:3 separates; Form the air channel vacuum, increased the air quantity exchange rate, reach the highest inspiration and draft capacity.
The present invention discloses a kind of fixed form of division board, said division board is vertical to insert big wind wheel blade, with being integral of blade shaped structure, this plug-in type combination, not only can be so that fixing more firm, and dismounting, clean convenient.
As a kind of preferred blade shape, the invention discloses big wind wheel blade is that top and bottom is narrow, the trapezoid blade that the middle part is roomy; Fan blade 1/3 position of this shape more helps stressed; Fan blade gives the torque of wind wheel bigger simultaneously, more helps wind wheel and rotates, and the wind wheel velocity of rotation also can be higher; Thereby help further improving the suction air quantity, and then improve the purifying oil fume effect.
The present invention discloses said big wind wheel and little wind wheel blade edge is the technological means of circular arc; Because this design makes the blade windward side can more effectively accept wind-force; So can reduce the resistance of wind, the increasing exhaust amount further improves the fume exhaust function.
As further preferred range hood monoshell three wind wheel turbine assembly structures; The present invention has further carried out the qualification of concrete size to big wind wheel, little wind wheel fan blade and spacing and discloses; Said strong wind size of wheel is the 245X136 millimeter; Little wind wheel is of a size of the 100X42 millimeter, and big wind wheel division board is the 90X40 millimeter, the gap ratio 4:1 of the spacing of said big wind wheel blade and little wind wheel blade.The inventor is on the basis through a large amount of tests, comparison, and the range hood monoshell three wind wheel turbine assembly structure suction air quantity that draw above-mentioned size are maximum, and suction oil effect is best, and noise is minimum, is optimal selection scheme of the present invention.
In sum, the present invention compared with prior art, its beneficial effect is conspicuous; Adopt the disclosed technical scheme of the present invention; Improved suction air quantity and purifying oil fume effect effectively, strengthened reasonable fume exhaust effect, the operation air quantity is steady; The operation noise is little, has really realized low-carbon (LC), energy-saving and environmental protection, the purification, durable of range hood.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is an AA sectional view among Fig. 1;
Wherein 0-housing, the big wind wheel of 1-, the big wind wheel blade of 1-1-, the little wind wheel of 2-, the little wind wheel blade of 2-1-, the import of 3-oil smoke, the outlet of 4-oil smoke, 5-motor output shaft, 6-division board.
The specific embodiment
As depicted in figs. 1 and 2; Range hood monoshell three wind wheel turbine assemblies comprise big wind wheel 1 that is used for oil smoke suction and purification and the little wind wheel 2 that is provided with in the Scroll-type housing 0 of oil smoke outlet 4, the oil smoke import 3 that is arranged at the housing side face, the housing; Wherein big wind wheel 1 is the turning cylinder edge even blade spaced apart of circumference separately with little wind wheel 2 with motor output shaft 5; Formed big wind wheel by the big wind wheel blade 1-1 of 60 245X136 millimeters form, little wind wheel is made up of 15 little wind wheel blade 2-1 of 100X42 millimeter; Ratio according to 1:3 on the wherein big wind wheel 1 is provided with division board 6; Division board 6 vertical fixing between big wind wheel 1 adjacent blades 1-1, thereby be the no gap wind wheel of 1:3 with the ratio that big wind wheel 1 is divided into two coaxial rotation.Start the range hood motor, motor output shaft 5 rotates, and then drives big wind wheel 1 and 2 motions of little wind wheel; Form three-dimensional wind-force because the no gap wind wheel of two coaxial rotation and air inlet and air outlet cooperatively interact this moment, because two big wind wheels 1 are to be separated through division board 6 by a big wind wheel 1 of integral body; So between do not have the gap, strengthened the negative pressure in the housing 0 greatly, overcome the problem of wind-force scattering in the conventional wind wheel structure; Make wind direction same; Wind-force is even, and the range hood exhaust air rate increases, thereby has improved range hood efficient.Little wind wheel is further evolved oil smoke, thereby has further improved the evolution rate of oil smoke.Through actual test, under said structure, the fume exhaust rate reaches 99%, and purifying rate 98% has really been realized low-carbon (LC), energy-saving and environmental protection, purification.
