Embodiment
For further specifying the purpose of this utility model, institute's application technology means and technique effect thereof, will lift preferred embodiment and be described in detail as follows:
Referring to figs. 1 through Fig. 3, the utility model provides a kind of centrifugal fan light fixture group, comprising: a centrifugal fan 1, a motor 2, a volute 3, a ring-type lampshade 4 and a shell 5; Wherein,
Ring-type lampshade 4, this ring-type lampshade 4 itself be provided with a central hole 40 and be installed in centrifugal fan 1 and volute 3 under, and ring-type lampshade 4 and volute 3 interior place, an inverted arc angle 41 common exhaust outlets 34 that form on every side, be provided with one first lamp body 42 in this ring-type lampshade 4, the central hole 40 of this ring-type lampshade 4 is established an oblique chamfer surface 401, and this oblique chamfer surface 401 to these central hole 40 integral body are horn-like.
As shown in Figure 3, form centrifugal fan light fixture group of the present utility model by said modules, the top sheet 11 of centrifugal fan 1 is respectively equipped with auxiliary flabellum 13, the centrifugal flabellum 12 of FC up and down, cooperate volute 3, ring-type lampshade 4, driving the air of these centrifugal fans 1 under extracting from center suction opeing 121 outlet section 122 through the acceleration of the centrifugal flabellum 12 of this FC and around the centrifugal fan 1 by motor 2 penetrates, exhaust outlet 34 through volute 3 blows out again, and this is a first flow 7.Another exhausting approach is to be extracted by auxiliary flabellum 13, there is one second runner 8 to penetrate in a plurality of inlet holes 36 of the inner concavity portion 32 of volute 3 from gas-entered passageway 53, this second runner 8 is joined at auxiliary exhaust outlet 33 and first flow 7 at last, so can increase air output of the present utility model.The utility model device makes volute 3 convergents into the 360 ring-like convergents up of spending, and the dynamic pressure in the runner can evenly and be reduced because of the loss that flow-disturbing produced, and allows the kinetic energy advantage of the centrifugal flabellum 12 of this FC be brought into play.
Please refer to Fig. 5 and Figure 12, centrifugal flabellum 12 curves of the FC that another design that can improve air output is exactly a centrifugal fan 1.As shown in the figure, centrifugal fan 1 comprises blade 123 and impeller 124, centrifugal fan 1 rotates (direction among the figure shown in the arrow) along clockwise direction, usually, the flabellum of centrifugal fan has FC, radial, BI or the like, and how to go to distinguish these three types, generally be that size with blade angle (β) is as foundation, the blade angles of the centrifugal flabellum 12 of FC is greater than 90 degree, and the blade angles of the centrifugal flabellum 15 of radial equals 90 degree, and the blade angles of the centrifugal flabellum 16 of BI is less than 90 degree.The size of the blade angle (β) of the centrifugal flabellum 12 of the FC of the utility model centrifugal fan 1 is made as greater than 90 degree, and so this blade angle (β) almost can all be changed the air quantity kinetic energy that kinetic energy is given air-flow and obtained maximum.
Therefore by the combination of each assembly of the utility model, create more air-flow path, at last the air-flow in each air-flow path is being compiled, add this centrifugal fan 1 again and adopt the centrifugal flabellum 12 of FC, can improve the whole air output of centrifugal fan 1 in view of the above.And for example Fig. 4, Fig. 5 and shown in Figure 6, center suction opeing 121 area A of centrifugal fan 1 greater than exhaust outlet area B and exhaust outlet area B greater than the sectional area C of gas-entered passageway (A＞B＞C), that is the exhaust outlet flow volume E of centrifugal fan 1 is the flow volume D of center suction opeing and gathering greater than the flow volume F of gas-entered passageway, cooperate the narrower exhaust outlet of lamp device 24 simultaneously, make the utility model can produce the air quantity of spreading far and wide journey.Simultaneously, the utility model produces the pattern that the circulation of air flow mode is different from conventional fan, it takes central air induction, and cross the mode of wind from ring, circulate with formation, the probability that flow-disturbing is taken place drops to minimum, cuts sound to reduce the whole wind of the utility model, builds the indoor more nice and cool quiet environment that reaches.
As shown in Figure 3, another exhausting approach is to be extracted by auxiliary flabellum 13, there is one second runner 8 to penetrate in a plurality of inlet holes 36 of the inner concavity portion 32 of volute 3, the heat radiation of motor 2 also is provided when making centrifugal fan 1 action, the life-span of motor 2 is prolonged from gas-entered passageway 53.
Please refer to Fig. 8 to shown in Figure 10, because center of the present utility model suction opeing 121 is positioned at the below of centrifugal fan 1, make the return air space not be subjected to spatial constraints fully, also can look the environment required lamp device of freely arranging in pairs or groups, can provide more various lamp body to change, in other words, make the utility model can apply to hang, embed, inhale the form on top.For example Fig. 8 and shown in Figure 9 is second, third embodiment's of the utility model stereo appearance figure, and it also comprises one second lamp body 6, wherein this shell 5 around set a plurality of support and connection framves 54, to connect and to fix second lamp body 6 of this ring type.As shown in figure 10, be the utility model the 4th embodiment, it also comprises one second lamp body 6, is outward extended with a plurality of wing seats 55 around this shell 5, makes this lamp device integral body star-shaped, is equiped with one second lamp body 6 in this each wing seat 55.Above-mentioned second embodiment to the, four embodiments, its topmost advantage is that this centrifugal fan 1 is not disturbing second lamp body to finish installation 6 times, makes set first lamp body 42 of the utility model, second lamp body 6 all can not have the situation of dazzle to take place because of the rotation of centrifugal fan 1.
Comprehensive the above, the centrifugal fan light fixture group that the utility model provides, its centrifugal fan is the principle of utilization multiple wing type air-driven machine, the centrifugal force that produces when utilization runs up, add the design of non-traditional formula volute gas collection fan housing, and take and the vertical vortex street of standing on the parallel homogeneous radiation of leaf dish of flabellum, make the stream of working off one's feeling vent one's spleen in the shortest distance, to be quickened smoothly to send by guiding, because distance is short and ring-like air channel interior profile is the vortex filament convergent, improved traditional volute gas collection greatly to FC flabellum energy loss height, the problem that efficient is not high, allow FC multiple wing flabellum theoretical maximum lift and maximum kinetic energy be brought into play, and keep certain air quantity.
It should be noted that at last: above each embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps some or all of technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment's technological scheme of the utility model.
