Ceiling fan TW two wire electronic timing speed regulator

The design relates to a kind of TW two wire electronic timing speed regulator, and it has realized the exchange (see figure 1) fully of electronic timing speed regulator and inductance type speed regulator in two electric tie modes; It holds identical speed ratio to the ceiling fan of different size, has realized the generalization of hanging fan governor; It has the high precision timing (minimal error can reach second level) of step-less adjustment and the rotating speed control of step-less adjustment, the real multifunction of hanging fan governor; It has realized the greenization of hanging fan governor with little power consumption (about 1 watt of maximum power dissipation), energy-conservation (power saving rate nearly 100% of inductance type speed regulator relatively) and pollution-free (electrical network is not had inrush current impact and spike interference, the space is not had Electromagnetic Interference and noise interference).

In existing technology, two class hanging fan governors are arranged, a class is the inductance type speed regulator, a class is that common electrical minor speed regulator (is seen Fig. 2-c, Fig. 2-d).The inductance type speed regulator is since being born, continue into the present with its advantage that is simple and easy to make, though the back has the common electrical minor speed regulator of some shortcoming that can overcome it to want to replace, because of the deficiency of self, in application, be difficult to promote, so the inductance type speed regulator still rules all the land.The shortcoming of the two shows as respectively: inductance type speed regulator power consumption is big, heating value big (severe patient is burnt out), and the contact easily produces spark, and the life-span is short, and consumption copper is many etc.; Common electrical minor speed regulator has pollution, and is more than the inductance type speed regulator with the electric tie of external circuit, can not exchange mutually with the inductance type speed regulator.In addition, the two does not all possess high-precision timing function.

This shows that inductance type speed regulator and common electrical minor speed regulator are not green electrical equipment.

The design's purpose provides a kind of novel multifunctional electronic governor, it not only can replace the inductance type speed regulator fully, but also realized the high precision timing and the step-less adjustment rotating speed of step-less adjustment, it is exactly that TW two wire electronic timing speed regulator (is seen Fig. 1, Fig. 2-a).

The design's purpose is achieved in that

This TW two wire electronic timing speed regulator is provided with a major loop, a control loop.Major loop is made up of converting power source (supply convertor) and drive controller, and control loop is made up of speed controller and timing controller.

In major loop, converting power source is after connecting power supply, offers the direct-current working volts of drive controller, speed controller and timing controller, realizes that electronic speed regulator connects the formation TW two wire with external circuit; Drive controller be accept speed controller and regularly (time) controller control and carry out the control that ceiling-fan motor running speed and commentaries on classics are stopped.

In control loop, speed controller and time control provide rate signal and time to cut off control signal to drive controller respectively.

Below in conjunction with drawings and Examples the design is further described.

In Fig. 1 and Fig. 3, TW two wire electronic timing speed regulator [1] is very simple with connecting of external circuit, and its tenminal block [19] joins by the live wire L of lead [6] with power supply, and terminal [20] links by the motor M of lead [7] with ceiling fan [9].This shows that TW two wire electronic timing speed regulator [1] has only 2 with the tie of external circuit, i.e. line [6] and [7].Ceiling-fan motor M connects with the zero line N of power supply by lead [8] again, finishes whole connection the between TW two wire electronic speed regulator [1] and ceiling fan [9] and power supply.

In Fig. 1, power switch [2] is a singly-key type switch with lock, presses to opening, and is locked on the low order position and (uses

Expression), click, power switch [2] resets again, and promptly is on the upper level position (to use

Expression); Speed regulator [4] is the rotating speed of control ceiling fan [9], and dextrorotation is during to maximum position, the rotating speed maximum (at full speed) of ceiling fan [9], and left-handed is minimum speed during to minimum position; Time regulator [5] is control ceiling fan working time, and dextrorotation is during to maximum position, the time the longest (〉=210 minutes), and left-handed during to minimum position, the time the shortest (≤20 minutes); Indicator [3] is the indication power supply.

In Fig. 1, TW two wire electronic timing speed regulator [1] is work like this: press switch [2], ceiling fan [9] starts and is remembered with speed regulator [4] the speed running of (or default), simultaneously, timing governor [5] picks up counting, after waiting to count the time of former memory (or default), ceiling fan [9] stops operating automatically.In the process of ceiling fan [9] running, also can carry out step-less adjustment arbitrarily to ceiling fan [9] running speed and time by [4] and [5].

In Fig. 3, major loop [13] is mainly by power switch [2], conversion electricity former [15], drive controller [16], indicator [3], capacitor C ₁Form.Indicator [3] is again by R ₁, LED forms.The effect of major loop [13] has the current path that provides ceiling-fan motor M at three:, drives the ceiling fan running; The 2nd, the control command of execution speed controller [17], time-controller [18] is being controlled running speed and the working time of ceiling-fan motor M, reaches speed governing and purpose regularly; The 3rd, provide direct-current working volts to all controllers, this voltage from the pin of converting power source [15] 2.
