In order to overcome the defects that the prior speed regulator is easy to be damaged, the hand feeling of the speed regulation is bad, the power sources of the speed regulator and a whole circuit can not be opened and closed simultaneously, the potential security hazard is existent and the electric energy is damaged, the utility model is in series connected with a silicon controlled switch circuit on the power source of the fan motor, a bidirectional trigger diode and a mechanical gear shifter for changing the electric quantity o f control electrodes are in series connected on the silicon controlled control electrodes of the silicon controlled switch circuit, and a power switch rotated and interlocked through the gear shifter is in series connected on the silicon controlled anode of the silicon controlled switch circuit. The utility model is mainly used for the ceiling fan as the power source switch and the speed regulation, the utility model has low cost, and exact speed regulation, the control is double and the energy is saved, and the utility model is durable.
Description
Technical field
The utility model relates to a kind of electrical equipment, is specially a kind of electric fan dual-control energy-saving speed regulator.
Background technique
Existing fan governor has gear coil type speed regulator, no electrode potential speed regulator and electric capacity speed regulator etc. in particular for the speed regulator of ceiling fan.Though the gear shift of gear coil type speed regulator is definitely accurate, meet the feel custom, volume is big, and consumptive material is many, and the valency height easily produces electric arc during gear shift, and working life is short; No electrode potential speed regulator is controlled fan speed by regulator potentiometer, though use flexibly, feel is poor, and elements such as potentiometer are fragile, are not durable, and is prone to fault such as to disconnect; The electric capacity speed regulator is regulated fan speed by series and parallel electric capacity control electric weight size, and its deficiency is that certain energy consumption is arranged itself, can not rotate by 360 degree, easily produces electric arc during gear shift, influences working life.
The model utility content
The purpose of this utility model will overcome above-mentioned deficiency exactly, gather its advantage, a kind of feel gear shift custom that meets is provided, can rotate by 360 degree, gear shift does not produce electric arc, and two controls disconnect, assurance is perfectly safe and is energy-conservation, and speed governing, switch are definite, and cost is low, the electric fan dual-control energy-saving speed regulator of long service life.
For achieving the above object, the technical solution of the utility model is, this electric fan dual-control energy-saving speed regulator comprises fan electromotor, the gate turnoff thyristor circuit of on the power supply of described fan electromotor, having connected, at connected on extremely bidirectional trigger diode and change the selector of this control utmost point electric weight of the SCR control of this gate turnoff thyristor circuit, at the controllable silicon anode of this gate turnoff thyristor circuit the power switch of having connected by described selector gear shift coupled switch by gear shift.Like this, by rotation selector knob, get final product the power supply of the while switch SCR control utmost point and anode, two controls thoroughly disconnect the power supply of fan electromotor, and electric fan switch and speed governing are up to state standards fully.
Described power switch is the mechanical contact-type switch.
Described selector is a mechanical knob formula selector, its each gear resistance that resistance is different of having connected, this resistance be connected on the bidirectional trigger diode that SCR control extremely goes up and connect.
Compare with the speed regulator of existing electric fan especially ceiling fan, the utility model gate turnoff thyristor circuit of on the power supply of described fan electromotor, having connected, extremely go up in the SCR control of this gate turnoff thyristor circuit and to have connected bidirectional trigger diode successively and to have changed the mechanical gear shift device of this control utmost point electric weight by gear shift, at the controllable silicon anode of this gate turnoff thyristor circuit the power switch of having connected by described selector gear shift coupled switch, realized that gear shift meets the feel custom, can rotate by 360 degree, gear shift does not produce electric arc, can twoly control the power supply that disconnects the SCR control utmost points and anode, assurance is perfectly safe and is energy-conservation, its speed governing, switch is definite, cost is low, long service life.
Description of drawings
Fig. 1 is that the utility model has removed the selector joystick knob and will be installed in the schematic representation of power switch place broken section on the selector.
Among the figure, 1. fan electromotor, 2. power switch, 3 selectors.
Embodiment
As shown in Figure 1, this electric fan dual-control energy-saving speed regulator comprises fan electromotor [1], and the gate turnoff thyristor circuit of having connected on the power supply of described fan electromotor [1] is extremely gone up the bidirectional trigger diode VD that connected successively in the control of the controllable silicon VS of this gate turnoff thyristor circuit
2With the selector [3] that changes this control utmost point electric weight by gear shift, at the controllable silicon VS of this gate turnoff thyristor circuit anode the power switch [2] of having connected by described selector [3] gear shift coupled switch, power switch [2] is the mechanical contact-type switch, an one contact connects with power supply, its another contact connects with controllable silicon VS anode, it touches by being installed in the selector [3] and by the spring actuating mechanism that its knob wheel drives, realize the closure and the disconnection of two contacts, described selector [3] is a mechanical knob formula selector, its each gear resistance that resistance is different of having connected is respectively R
1-5, this resistance R
1-5Be connected on the bidirectional trigger diode VD that controllable silicon VS control is extremely gone up
2Series connection.
When the knob of selector [3] is threaded to disconnection place, position (situation as shown in Figure 1), two contacts of power switch [2] are owing to the conflict of spring actuating mechanism disconnects, this moment controllable silicon VS the control utmost point and anode and all disconnect by the fan electromotor [1] of this anodic control with power supply; When the knob of selector [3] is threaded to resistance R
1-5The connecting terminal place time, two make contact of power switch [2], this moment controllable silicon VS the control utmost point and anode and all and power connection by the fan electromotor [1] of this anodic control, and be connected to different resistance (R along with the knob of selector [3]
1-5) the connecting terminal place, the electric weight that makes fan electromotor [1] changes and regulates its rotating speed.
