Description

A kind of on-bladed electric fan
Technical field
The present invention relates to a kind of electric fan, especially relate to a kind of on-bladed electric fan.
Background technique
Compare with traditional electric fan, no leaf electric fan has characteristics such as low noise and Security be good.Chinese patent number is 200990100311.8 the utility model patent that a kind of name is called " on-bladed fan component and nozzle thereof " that discloses, and its structure comprises device and the nozzle that is used to form air-flow, and this nozzle comprises the inner passage and the mouth that is used to launch air-flow that is used to receive air-flow; Nozzle extends around an axis; To limit an opening, dragged suction through opening from the fan component air outside from the air-flow of mouth emission, nozzle comprises a surface; Mouth is set on this surface with steering flow; This surface comprises diffusion section and guide portion, and this diffusion section is taperedly away from axis, and this guide portion is also angled with it in the diffusion section downstream.Nozzle is a ring nozzle; But wall attachment effect and Bernoulli's equation wp=0.5rov2 according to Condar can know; Air-flow in the ring nozzle has the characteristic that upwards flows, and makes stream pressure in ring nozzle, increase gradually from lower to upper, and the air-flow that ejects from mouth from bottom to top has bigger difference in flow; Because the outside air quantity that the uneven distribution of air-flow can cause jet-stream wind to aspirate is smaller, so the Energy Efficiency Ratio of electric fan can be lower.
Summary of the invention
Technical problem to be solved by this invention provides the on-bladed electric fan that a kind of air output is big, Energy Efficiency Ratio is high.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of on-bladed electric fan; Comprise the device and the ring nozzle that are used to form air-flow; This ring nozzle comprises the annular pass and the opening that is used to launch air-flow that is used to receive air-flow, is provided with a plurality of barge boards in the described annular pass, and described a plurality of barge board annular spread are in the annular pass; Described barge board is divided into multistage with described annular pass and holds air chamber; Described barge board is divided into separate a plurality of mouths with opening, and each holds the corresponding mouth of air chamber, and described a plurality of mouths constitute the mouth combination along annular spread; Barge board blocks the part air-flow that flows from lower to upper in the annular pass, and the air-flow that described barge board will hold in the air chamber is directed to each mouth ejection.Barge board blocks the part air-flow that flows from lower to upper in the annular pass, avoids too much air-flow to accumulate in the top of annular pass, makes the air pressure that respectively holds in the annular pass in the air chamber impartial as far as possible, and the throughput of each mouth ejection is equated.
The area of described barge board accounts for 1/5～2/3 of annular pass sectional area.Barge board can block upwards airflow flowing of part, is unlikely to make the air-flow on top, annular pass very few again.
Described nozzle comprises outer ring panel and internal spherical surface plate, and described annular pass is surrounded by outer ring panel and internal spherical surface plate, and described barge board is fixed on the back side of internal spherical surface plate.
Described barge board is obliquely installed at the back side of internal spherical surface plate, and barge board is higher than the level height away from the mouth end near the level height of mouth end.The barge board that is obliquely installed can more successfully import to each mouth with the air-flow that each holds in the air chamber with air-flow, meets the characteristic of air-flow.
Described barge board is curved shape.Make air current flow property better, meet the characteristic of air-flow.Barge board can import to each mouth with air-flow better.
Described barge board is the spiral of Archimedes shape.The barge board water conservancy diversion better effects if that meets the spiral of Archimedes shape.
The device that forms air-flow comprises the turbosupercharging motor; The turbosupercharging motor imports to described inner passage through flow guide device with air-flow; Flow guide device is arranged on the top of turbosupercharging motor, and ring nozzle is arranged on the top of flow guide device, and the bottom, annular pass is stretched in the flow guide device upper end.
Described turbosupercharging motor comprises motor cover and exhaust outlet; Described exhaust outlet is distributed in the periphery of motor cover ringwise, the exhaust outlet of turbosupercharging motor up, described flow guide device comprises cirque body; One level and smooth extension the in cirque body both sides is provided with first guide plate; Two first guide plates are symmetrical set on the cirque body, and cirque body is seated on the motor cover, and the free end of described two first guide plates stretches into the two bottom sides of annular pass respectively; The free end of described first guide plate is close on the internal spherical surface plate, and first guide plate will be positioned at the air-flow guiding annular pass of the exhaust outlet ejection of the turbosupercharging motor under it.
Described cirque body is provided with second guide plate in both sides in addition; Second guide plate is between two first guide plates; Second guide plate is arranged on the top of the exhaust outlet of turbosupercharging motor, and second guide plate will be positioned at the air-flow guiding annular pass of the exhaust outlet ejection of the turbosupercharging motor under it.Second guide plate prevents that the air-flow of the exhaust outlet ejection of the turbosupercharging motor under it from upwards flowing.First guide plate and second guide plate all import to the air-flow of all exhaust outlet ejections of turbosupercharging motor in the annular pass.
Second guide plate is obliquely installed in the cirque body outside; One end level height of second guide plate is lower than the other end level height of second guide plate; The level height of second guide plate is provided with vertical isolating plate than low side; Described outer ring panel and internal spherical surface plate are wholely set, and the free end of outer ring panel is provided with the free end outside at the internal spherical surface plate, and the gap between the free end of the free end of outer ring panel and internal spherical surface plate forms described annular opening.The setting of vertical isolating plate can prevent that the air-flow of opposite side is mobile from the upper surface of second guide plate.
Compared with prior art; Advantage of the present invention is the characteristic according to high pressure draught, and the high pressure draught of traditional bottom, electric fan annular pass accumulates in the top of annular pass from lower to upper, and the part air-flow that the barge board that is provided with in the annular pass will upwards flow blocks; The stream pressure that the annular pass is respectively held in the air chamber is impartial; Impartial relatively from the throughput of each mouth ejection, also can increase greatly through the air quantity that air-flow aspirated that sprays at last, improved the Energy Efficiency Ratio of electric fan.
