Abstract
Fan leaf dish and fan that the powerful noise of a kind of wind-force is low, comprise a turntable along running shaft revolution design, described turntable is provided with the fan blade of some annular arrays, described fan blade is provided with some pits, described pit becomes some rows to be distributed in fan blade, equate with the each distance apart from running shaft of row's pit, the same row's pit in a fan blade has three at least.The beneficial effects of the utility model are: because becoming some rows, arranges pit, and consistent from running shaft distance with row's pit array pitch, therefore in rotary course, the air film that pit distribution produces is outer field more smooth, has reduced noise.
Description
Technical field
The utility model relates to a kind of electric fan and accessory thereof.
Background technique
The fan leaf dish of electric fan and motor have determined a fan performance, and the structure of fan leaf dish is more reasonable, and motor speed is faster, and wind-force is stronger.Once but wind-force is strong, fan leaf dish can form the noise of beating wind, very unpleasant to hear, in order to overcome noise, engineer arranges pit and form air film in the fan blade of fan leaf dish on fan, makes an uproar to reduce wind, but this pit that simply arranges on fan, the air film that pit distribution produces not is very smooth, does not reach the maximum performance of noise abatement and raising air quantity.
Summary of the invention
In order to overcome the existing pit that simply arranges on fan, do not reach the deficiency of the maximum performance of noise abatement and raising air quantity, the utility model provides the fan leaf dish that the powerful noise of a kind of wind-force is low and uses the fan of this fan leaf dish.
The technical scheme in the invention for solving the technical problem is: the fan leaf dish that the powerful noise of a kind of wind-force is low, comprise a turntable along running shaft revolution design, described turntable is provided with the fan blade of some annular arrays, described fan blade is provided with some pits, described pit becomes some rows to be distributed in fan blade, equate with the each distance apart from running shaft of row's pit, the same row's pit in a fan blade has three at least.
For improving the aeroperformance of fan leaf dish, the outer width of described fan blade is narrow, the curved indent of side windward of described fan blade, and the leeward side of described fan blade is straight.In the time of fan leaf disc spins, first fan blade windward side outer end drive air film first cut meet to wind in, then wind is scattered breaking wind along the lee face of fan blade, fairshaped external form breaks water layer just as ship tip, greatly reduce the noise that in the past adopts plane to bounce to cause, reduce the stressed of fan blade simultaneously, improved air-out speed.
The utility model also comprises the low fan of the powerful noise of a kind of wind-force, comprises the direct current generator of a fan leaf dish and drive fan leaf dish; Described fan leaf dish comprises a turntable along running shaft revolution design, described turntable is provided with the fan blade of some annular arrays, described fan blade is provided with some pits, described pit becomes some rows to be distributed in fan blade, equate with the each distance apart from running shaft of row's pit, the same row's pit in a fan blade has three at least.
Further, the outer width of described fan blade is narrow, the curved indent of side windward of described fan blade, and the leeward side of described fan blade is straight.In the time of fan leaf disc spins, first fan blade windward side outer end drive air film first cut meet to wind in, then wind is scattered breaking wind along the lee face of fan blade, fairshaped external form breaks water layer just as ship tip, greatly reduce the noise that in the past adopts plane to bounce to cause, reduce the stressed of fan blade simultaneously, improved air-out speed.
The utility model is consistent with fan with the fan leaf dish of prior art in use, does not repeat them here.
The beneficial effects of the utility model are: because becoming some rows, arranges pit, and consistent from running shaft distance with row's pit array pitch, therefore in rotary course, the air film that pit distribution produces is outer field more smooth, has reduced noise.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
By reference to the accompanying drawings 2 to 3, the fan leaf dish 1 that the powerful noise of a kind of wind-force is low, comprise a turntable 2 along running shaft 5 revolution designs, described turntable 2 is provided with the fan blade 3 of some annular arrays, described fan blade 3 is provided with some pits 4, described pit becomes some rows to be distributed in fan blade 3, equates with the each distance apart from running shaft 5 of row's pit 4, and the same row's pit 4 in a fan blade 3 has three at least.
For improving the aeroperformance of fan leaf dish, the outer width of described fan blade 3 is narrow, the curved indent of side windward 6 of described fan blade, and the leeward side 7 of described fan blade is straight.In the time that fan leaf dish 1 rotates, first fan blade windward side 6 outer end drive air film first cut meet to wind in, then wind is scattered breaking wind along the lee face 8 of fan blade, fairshaped external form breaks water layer just as ship tip, greatly reduce the noise that in the past adopts plane to bounce to cause, reduce the stressed of fan blade simultaneously, improved air-out speed.
By reference to the accompanying drawings 1, the present embodiment also comprises the low fan of the powerful noise of a kind of wind-force, comprises the direct current generator 9 of a fan leaf dish 1 as above and drive fan leaf dish.
The present embodiment is consistent with fan with the fan leaf dish of prior art in use, does not repeat them here.
The beneficial effect of the present embodiment is: because becoming some rows, arranges pit, and consistent from running shaft distance with row's pit array pitch, therefore in rotary course, the air film that pit distribution produces is outer field more smooth, has reduced noise.
