Abstract
The utility model relates to a speed regulator for breeze of an electric fan, comprising the main winding m of a motor M, a secondary winding a of the motor M, and speed-regulating switches K1, K2, K3, and is characterized in that the utility model adopts a double contact piano keyboard linkage switch KWF as a breeze shield switch and the double contact piano keyboard linkage switch KWF is connected with a part of taps of the secondary winding. A diode D is connected with the switch. When the switch is switched on, a part of the winding of the motor inputs definite DC component to lead the starting voltage of the motor not to be decreased to obtain breeze speed regulation. The utility model has the advantages of simplicity and good breeze effect.
Description
The utility model relates to electric fan speed governing field, particularly a kind of speed regulator of realizing tap speed governing electric fan gentle breeze retaining that is applicable to.
Common fan has two kinds of modes of speed regulation, i.e. two kinds of tap speed governing and reactance speed governing.The tap speed governing will realize that there are two difficulties in the gentle breeze retaining, the one, bother on the technology, and quality is difficult to be guaranteed, the 2nd, gentle breeze retaining tripping force deficiency does not reach the requirement that new national standard starts electric fan.And there is the high deficiency of production cost in the reactance speed governing.
The purpose of this utility model is to provide a kind of and can satisfies new national standard electric fan is started requirement, is applicable to the speed regulator of realizing tap speed governing electric fan gentle breeze retaining.
Above-mentioned purpose of the present utility model is to realize by such technical scheme, be that the utility model comprises that the main winding of tap buncher is connected with the tap of auxiliary winding with an auxiliary winding and an end, the speed-regulating switch group that the other end is connected with main winding, it is characterized in that adopting two contact key linked switches to make the gentle breeze position switch, one end of one switch contacts of this linked switch keeps off in the tap of speed governing by the end that diode is connected on auxiliary winding, in time speed governing retaining tap of another termination auxiliary winding; In the end retaining speed governing tap of one termination auxiliary winding of another switch contacts, another termination main winding.
Said structure of the present utility model is further specified by the embodiment that accompanying drawing provides.
Accompanying drawing is a structural representation of the present utility model.
Referring to accompanying drawing, motor M comprises main winding m among the figure, auxiliary winding a and capacitor C, wherein three retaining speed-regulating switch K
1, K
2, K
3The speed governing tap of a termination auxiliary winding, another termination main winding m, two contact key linked switch KWF are gentle breeze retaining speed-regulating switch, and an end of one switch contacts keeps off in the tap of speed governing by the end that diode D is connected on auxiliary winding, and the other end is connected in the tap of the retaining speed governing in the auxiliary winding; The end that one of another switch contacts terminates at auxiliary winding keeps off in the tap of speed governing another termination main winding m.
The utility model is owing to sealed in a diode D in gentle breeze position switch KWF, when KWF connects, promptly in the motor section sub-winding, import certain direct-current component, to lower rotating speed of motor, thereby realize the purpose of gentle breeze speed governing, because the tripping force of electric fan is identical with the end retaining, thereby guaranteed the requirement of new national standard to starting.
The utility model is because to adopt its effect of said structure be conspicuous, and promptly in that to realize having method aspect the speed governing of gentle breeze retaining simple, cost is extremely low, very easily implements and characteristics that the gentle breeze retaining is satisfactory for result.
