Abstract
In the currently used various domestic electric fan, an inductor is commonly used for speed regulation; the performance of speed regulation is very poor with in the range of low speed. An electric fan, in which a synthetical mode of speed regulation with the inductor and a capacitor is used, has a wide range of speed regulation, particularly a novel electric fan which has the performance of both a common electric fan and a Hongyun electric fan and can obtain zephyr which is similar to natural winds. By trying out on five grades of electric fans, the utility model has the advantages of ideal speed regulation performance and low noises; energy is saved by 14%; cost is only increased by 5%.
Description
Belong to household electrical appliance technical field.
Existing domestic electric fan generally adopts single-phase AC motor to drag.For satisfying the selection of user to electric fan air-supply size, being equipped with the inductor of band tap and the alignment circuit of throw over switch composition is serially connected in the main circuit, adopt the mode of adjusting voltage to change motor speed, thereby the air quantity size that fans is sent change thereupon.If require the electric fan rotating speed to reduce the more, then inductance value also need increase the more.Like this, not only increased the volume and the energy consumption of inductor, but also cost is increased.Therefore, at present the speed adjusting performance of normal domestic use electric fan in low-speed range is relatively poor, can not satisfy people to the demand of wind.The good luck electric fan of being sold in the market can be sent softer wind, but it is not to utilize that the slow-speed of revolution of fans produces and wind, but installs a rotatable refraction cover additional at the front end of fan, and the mode of adopt refraction, disperseing obtains.This mode has not only been wasted electric energy, and the noise that produces is also bigger.
Developing this novel electric fan is in order to produce a kind of electric fan that integrates the advantage of common electrical fan and good luck electric fan.It is big to make it not only to have speed adjustable range, desirable low speed governing performance, utilization ratio height, but also have low energy consumption, low noise, characteristics cheaply.
The overall structure of novel electric fan is compared with existing various normal domestic use electric fans, and main difference is at circuit part.The circuit of novel electric fan is inductor L, the starting capacitor C by single-phase AC motor D, band tap
1, speed governing capacitor C
2, throw over switch K
1With diverter switch K
2Constitute Deng components and parts.As shown in drawings.Wherein single-phase AC motor D and starting capacitor C
1Form single-phase electricity container motor.One termination power of motor lead, the other end connects with the terminal tap of inductor L, remaining tap of inductor L in order respectively with throw over switch K
1Stationary contact connect throw over switch K then
1Movable contact not only directly and diverter switch K
2Stationary contact connect and serial connection speed governing capacitor C
2After again with diverter switch K
2Another stationary contact connect.Last diverter switch K
2Movable contact connect with power supply.As diverter switch K
2Put speed governing capacitor C at 1 o'clock
2Open circuit, have only inductor L and throw over switch K in the circuit this moment
1The inductance alignment circuit of forming works, and its result is the same with the common electrical fan, can obtain third gear than high wind.As diverter switch K
2Put speed governing capacitor C at 2 o'clock
2Put in circuit, have inductor L and speed governing capacitor C in the circuit this moment
2The comprehensive alignment circuit of forming works, and its result is similar to the good luck electric fan, can obtain the more weak wind of third gear.Therefore novel electric fan can possess six grades of rotating speeds at least, according to the test result on five kinds of trade mark electric fans, if be standard with best weak wind, and speed governing capacitor C
2Span: 1 μ F-2 μ F, 450 volts of pressure resistances.
Novel electric fan is compared its advantage with existing various electric fans: (1) all has desirable speed governing effect at high and low rotating speed, and that particularly sends when low speed is more pleasant with wind.(2) novel electric fan integrates advantage common, the good luck electric fan.Purchase its function of novel electric fan and push up existing common, two electric fans of good luck, utilization ratio improves greatly, and expense increases seldom.(3) through actual test, novel electric fan is more energy-conservation about 14% than existing electric fan when low-speed running, and noise obviously reduces.
The operation of novel electric fan is very simple.On the basis of existing various single phase alternating current electric fans, only need speed governing capacitor C
2With diverter switch K
2Add to install and get final product.Needn't do big change.
There is any to please note: as diverter switch K
2Put inductor L and speed governing capacitor C at 2 o'clock
2Be connected into series connection.By formula | X
L-X
G| know that the effect of inductance and electric capacity is cancelled out each other.Therefore, throw over switch K at this moment
1It is minimum to put 1 o'clock motor speed.This and diverter switch K
2The adjusting order of putting at 1 o'clock is just in time opposite.For the convenience of using, can be at throw over switch K
1Or diverter switch K
2Last work a bit improves.Make the speed governing sequence consensus of novel electric fan the time than high wind and more weak wind state.
