Abstract
A single phase alternating current voltage adjustment speed change fan is characterized in that thyristors are connected to the power supply input end of a motor in series. The single phase alternating current voltage adjustment speed change fan solves the problems that when a frequency converter is utilized to adjust speed change of the fan, cost is high and operation of other online equipment is interfered, and the single phase alternating current voltage adjustment speed change fan is widely applied to the situation where the power is below 1KW.
Description
Technical field
The present invention relates to field of household appliances, is a kind of single phase alternating current (A.C.) blower fan that changes motor rotary speed by controllable silicon regulation voltage specifically.
background technology
The single phase alternating current (A.C.) blower fan using on present society, is all that blower motor is connected with frequency converter, by changing incoming frequency, realizes blower fan speed change.Its shortcoming is that frequency converter purchase cost is high, produces harmonic pollution electrical network, disturbs online other equipment operations; The PWM ripple of output, can cause the extra heating of motor, cable
.
Summary of the invention
The present invention adopts frequency converter to regulate blower fan speed change cost high for solving, and disturbs the problem of online other equipment operations, has designed a kind of blower fan of realizing speed change by silicon-controlled voltage regulation.
Technical scheme of the present invention is, a kind of single phase ac regulation speed-changing draught fan, and its special character is, at the power input of motor, is in series with controllable silicon.By controllable silicon, regulate the voltage of blower motor, change moment of torsion and the torsion of blower fan, the rotating speed of blower fan is changed.
Technique effect of the present invention is that employing technique scheme, can realize single phase ac regulation speed-changing draught fan a kind of simple in structure, easy to operate.It regulates the voltage at blower motor two ends by minute pressure-controlled of thyristor operating angle, changes output torque, the torsion of blower motor, not only realized the speed change of single phase alternating current (A.C.) blower fan cheaply, and when the blower fan slow-speed of revolution, saving electric energy that can be a large amount of, realizes energy-conserving and environment-protective object.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention, and the accompanying drawing that makes an abstract.
In the drawings, 1 motor, 2 motor power inputs, 3 controllable silicons.
Embodiment
Below in conjunction with accompanying drawing example, the present invention is further described.
As shown in the figure, on the motor power input 2 of motor 1, be in series with controllable silicon 3.The voltage that regulates blower motor 1 by controllable silicon 3, changes the rotating speed of blower fan.
Claims (1)
1. a single phase ac regulation speed-changing draught fan, is characterized in that: the power input at motor is in series with controllable silicon.
