Abstract
The invention relates to kitchen extractor hoods in daily life and particularly relates to an inserted portable small fan blade extractor hood. The inserted portable small fan blade extractor hood comprises a housing, a ventilating duct, fan blades, a motor and a bracket, wherein the motor is mounted on the bracket; the bracket extends outward to form a supporting arm; and the outer end part of the supporting arm is connected to the housing in an inserted manner. The inserted portable small fan blade extractor hood is characterized in that the output shaft of the motor faces one side of an air outlet of the ventilating duct, and the fan blades are mounted on the output shaft of the motor through threaded connection; the fan blades have a hub, the three blades are uniformly distributed around the hub, each blade is a straight-sided curved structure which is wide in the upper part and narrow in the lower part, the bending radian of the curved surface is 0.14-0.18, and the total area of the curved surface of the three blades accounts for 10-15% of the sectional area of the ventilating duct. The inserted portable small fan blade extractor hood provided by the invention is skillful in design, small in noise, low in power consumption, large in extraction force and convenient to clean, and has a good application prospect.
Description
Technical field
The present invention relates to the fume exhauster for kitchen in daily life, specifically a kind of Interposed portable little flabellum range hood.
Background technology
Currently, in some interim or little miniature places, kitchen, it is frequently used the most embedded (blade) smoke ejector, headkerchief suspension type (impeller) range hood conventional from urban family is different, the ventilating duct of this kind of smoke ejector and flabellum are the most exposed in the housing, and flabellum is positioned at the air inlet of ventilating duct, rotate under driven by motor, thus reaching the effect of mist extractor, its advantage is exactly simple in construction, cheap；But, due to for unenclosed construction, for reaching preferable convulsion oil extraction effect, this kind of smoke ejector on the market strengthens " suction " ability of flabellum often through big blade, mutliblade mode, the generally quantity of blade can reach 5-8, vaned area sum can reach the 60%-80% of ventilating duct area of section.
So, big blade, mutliblade mode, while strengthening " suction " ability of flabellum, also increase air drag, have noise when showing as pump drainage oil smoke very big, and power consumption increases simultaneously, and the attached pasta of blade amasss and increases the most therewith.
Summary of the invention
For solving above weak point, the present invention provides that a kind of noise is little, power consumption is low, draft is big and is easy to the Interposed portable little flabellum range hood of cleaning.
The present invention the specific scheme is that a kind of Interposed portable little flabellum range hood, including housing, ventilating duct, flabellum, motor and support, described motor is rack-mount, this support is outward extended with support arm, the outer end of support arm is connected with housing with insert structure, it is characterized in that: the output shaft of described motor is towards the air outlet side of ventilating duct, and flabellum is threaded connection and is arranged on motor output shaft；Described flabellum has wheel hub, and around three blades that are evenly distributed with for a week of wheel hub, every blade is straight flange globoidal structure wide at the top and narrow at the bottom, and the crooked radian of cambered surface is 0.14-0.18, and the gross area of three blade cambered surfaces accounts for the 10%-15% of ventilating duct area of section.
The outward extending support arm of support of the present invention, its outer end is the top with shell or following, or the left side, or the right is inserted and connected.
Described case top of the present invention be provided with can 90 ° open face shields, housing bottom is fitted with oil collection box.
The Heterosis that the present invention possesses exists:
1. change traditional big blade, multiple-blade, slow-revving pump drainage oil smoke form into vanelets, few blade, high-revolving form, solve that noise is big, the attached pasta of blade amasssManyDefect；
2. by flabellum design at ventilating duct tail end, increasing the negative pressure space in ventilating duct, contribute to blade and be partially separated by the profit in oil smoke, flue gas is arranged from air duct afterbody, and profit flows into oil collection box from lower end, road with the wind.

Detailed description of the invention
In the present embodiment, a kind of Interposed portable little flabellum range hood, including housing 1, ventilating duct 2, flabellum 3, motor 4, cylindrical stent 5 and the oil collection box 6 being positioned at housing bottom, described case top be provided with can 90 ° open face shields 7, described motor 4 is arranged on cylindrical stent 5, this cylindrical stent 5 is outward extended with support arm 8, and the outer end of support arm 8 is connected above with housing 1 with insert structure.
In the present embodiment, the output shaft of motor 4 is towards air outlet 9 side of ventilating duct 2, and flabellum 3 is threaded connection and is arranged on motor 4 output shaft；Described flabellum 3 has wheel hub 31, around three blades 32 that are evenly distributed with for a week of wheel hub 31, every blade 32 is straight flange globoidal structure wide at the top and narrow at the bottom, and the crooked radian of cambered surface is that this crooked radian of 0.14(can be at the arbitrary value within the scope of 0.14-0.18, radian is the least, takes out smoke discharging effect poor；Radian is too big, and noise is the biggest), the gross area of three blade cambered surfaces accounts for the 10%(of ventilating duct 2 area of section can be the least at the arbitrary value within the scope of 10%-15%, area, takes out smoke discharging effect poor；Area is too big, and noise is the biggest and power consumption is the highest).
In the present invention outer end of support arm 7 also can following with shell 1, or the left side, or the right inserts and connect.
Claims (3)
