Description
Technical field
The present invention relates to a kind of method for driving and wheeled fan of wheeled fan, belong to the electrical engineering technical field.
Background technique
The use of electric fan is with a long history, brought into use electric fan so far from 1830, and electric fan has been broken away from not the motor moulding that there is a heaviness flabellum center always.Though people are through the whole bag of tricks pursuing individualityization on outward appearance and function; But because this industry technology is more outmoded; The outward appearance fixed single; On the market common stand fan, rotary blade fan, desk fan, wall fan etc. several in the traditional type electric fans, the identical phenomenon of their outward appearance and function has very seriously had a strong impact on and has restricted the development and the lifting of electric fan.Electric fan industry development in future trend requires design to break through tradition with moving towards, and some main flow enterprises have developed a series of richer innovations one after another through actively innovation, have more the new product of differentiation individual character, in the hope of product up-gradation.Based on present international energy shortage, and the frequent situation about taking place of domestic severe power shortage in recent years, power saving function will be a very important developing direction.For the respite severe power shortage; Peak times of power consumption in full summer; Regular " power cuts to limit consumption " is inevitable; But heat is hard to bear, and people need also can enjoy the refrigerant sensation that fan blows when having a power failure, and at this moment perhaps utilizes solar energy just very suitable as the energy-conserving and environment-protective fan of the energy with the storage battery fan.This also will obtain the promotion and application than great dynamics in future.Above information source and mechano-electronic channel substation, these electric fan development trends have very big influence to the electric fan that will realize.
Summary of the invention
The objective of the invention is to overcome the defective of existing electric fan technology, provide a kind of method for driving and wheeled fan and said wheeled fan of the wheeled fan that can improve Energy Efficiency Ratio to have ultra-thin characteristics.
The present invention adopts following technological scheme:
The method for driving of a kind of wheeled fan of the present invention is:
A kind of wheeled fan of the present invention comprises annulus, impeller, support and rotating shaft, and said impeller is located in the annulus, on annulus, embeds 4 ~ 8 permanent magnet blocks and 4 ~ 8 permanent magnet blocks along circumferentially distributing, and reflective areas is set on annulus; The optoelectronic switch that equals electromagnetic coil group group number along 3 ~ 10 groups of electromagnetic coil groups and the quantity of circumferential arrangement is set on said support, and each optoelectronic switch is composed in series series loop with each electromagnetic coil group respectively; Said impeller forms through rotating shaft and support and is rotationally connected, and the surface that is provided with the annulus of permanent magnet block is faced with the surface of the support that is provided with electromagnetic coil and optoelectronic switch mutually; After powering on for each series loop and starting fan, reflective areas and optoelectronic switch meet and make the optoelectronic switch conducting, and the electromagnetic coil in the series loop accordingly gets electric and drive fan.
Compared with prior art, the present invention has following advantage:
At first change common electric fan flabellum design.The present invention adds circular ring plate in the electric fan fan end, and permanent magnet is installed on annulus, is evenly distributed on the flabellum annulus on every side, and magnetic pole is parallel with the annulus tangent line.On the outer toroid around the flabellum, on the ring between each permanent magnet, reflective marker is arranged, all the other positions adopt dead color to reduce reflective.In annulus electric fan shell behind, plurality of electromagnetic iron is installed, is circle distribution, radius and flabellum circular ring-shaped permanent-magnet iron phase are near, and to keep maximum force, the magnetic pole of generation is parallel with the annulus tangent direction, and polarity is opposite with flabellum circular ring-shaped permanent-magnet magnetic pole iron.The length of electromagnet should keep basically identical with the length of permanent magnet, and the spacing of electromagnet should be slightly less than permanent magnet length, to form staggered magnetic pole.On the shell at flabellum annulus rear, there be the photoelectric sensor corresponding to distribute with the electromagnet group number.Photoelectric sensor switch control direct current is controlled (or one group of 180 degree of a being separated by) electromagnet respectively, behind certain permanent magnet of the process of the permanent magnet on the flabellum, and electronic switch closes; Turn-on current; Work of electromagnet produces magnetic force with the permanent magnet that closes on, and promotes the flabellum rotation.
1. the present invention has the high advantage of Energy Efficiency Ratio.The present invention adopts and the distinct method for driving of common electric fan; Because it is that electromagnetic coil is positioned at the annulus edge that motor driving is positioned at the flabellum edge; Thereby make driving moment under limited spatial condition, maximize; Because moment of torsion=directed force F * radius can use less thrust to obtain than high pulling torque from principle analysis this method.The present invention is through comparing with the electric fan that adopts this identical flabellum, and the condition of contrast is under identical rotating speed, measures power consumption.Adopting gold to reach the logical contactless revolution counter of DT2234A and measures, is 520 to transfer benchmark to the finished product electric fan at certain gear rotating speed, and this wheeled electric fan adopts a direct current 12.5V to reach same revolution.This moment, electric fan was 21.2 watts through JNX-2000 electric energy metrical socket reading; This wheeled electric fan adopts direct current 12.5V power supply, and current sinking is 0.7 ampere, and power consumption is 8.75 watts, and consumed power almost is the half the of common electric fan.This electric fan adopts the power supply of 12.6V direct-flow storage battery in addition, is 6800mAH when adopting the battery nominal capacity, the sustainable work of electric fan 7 hours, and power consumpiton is less than 10 watts.The wheeled fan that this explanation the present invention adopts has the high advantage of Energy Efficiency Ratio.
2. because the present invention controls powering on of the electromagnetic coil that is flat on the support or electromagnetic coil group through optoelectronic switch; Electromagnetic coil that powers on or electromagnetic coil group interact with the permanent magnetic iron that is flat on the annulus; Make the fan rotation; Therefore, in technological scheme of the present invention, need not or saved commutator that existing electric fan must use, carbon brush etc., thereby structure of the present invention is tangible simple many than existing technology; And the horizontal set-up mode of electromagnetic coil or electromagnetic coil group and permanent magnetic iron makes axial thickness of the present invention obviously reduce.In a word, the present invention is a kind of extra-thin wheeled fan, and with respect to existing technology, its axial distance is very short, has light advantage.The wheeled control method for fan of employing uniqueness is distributed to middle electrocardiograph around the flabellum, has dwindled electric fan thickness greatly, and electric fan thickness almost is exactly flabellum thickness, and the electric fan thickness of processing is less than 60 millimeters.
3. this wheeled fan small volume and less weight energy consumption is low, and the electric fan structure is slim, adopts direct current supply, and storage battery power supply easy to use, so maneuverability are not limited by power line, can move everywhere, is particularly suitable for when operating a switch outage summer, using.
