Abstract

The utility model discloses a timed controller. The timed transition and the timed stop of the power are completed through an electrical timer controlling the timing action of a convertible contact set, so an electric fan or an electric cooker has smaller power converted from bigger power in given time or stops working. The utility model has simple structure, reliable work and low cost, and is used conveniently and practically.

Description

A kind of time cycle controller

The utility model relates to the control device of household electrical appliance, relates in particular to the timing transfer power automaton that is used for electric fan or electric-heating cooking utensil.

Electric fan develops into now, has formed big huge families such as a ceiling fan, desk fan, stand fan, wall built-up fan and box fan.Common electric fan has only arrangements for speed regulation, and to adjust the size of electric fan wind-force, some electric fan has single timing function, and regularly power cutoff is not worked electric fan, and this electric fan generally adopts mechanical timer.Diminish when people need make the wind-force of electric fan in official hour, these electric fans just can not be satisfied the demand.Same electric heating appliance (as electric cooker, electronics watt pot etc.) has only the gentle thermostatically-controlled equipment of simple limit, power controlling to change under specified temp usually, and regularly power cutoff or regularly transfer power.In order to realize this function, the someone adopts the electronic type timing device, and the someone adopts single card microcomputer to control, adopt the timer of this dual mode, to having relatively high expectations of working environment, production technology is comparatively complicated, production cost is also higher, these effects limit its range of application.

The purpose of this utility model provides a kind of time cycle controller, and it has regularly the function of transfer power or timing power cutoff, and the while is simple in structure, production is easy, cost characteristics lower, easy to use, is fit to the use of electric fan or electric-heating cooking utensil.

The purpose of this utility model is achieved in that a kind of time cycle controller, mainly constitute by electronic timer, its control convertible contacts group, be used for regularly transfer power of control, its moving contact and power supply one end join, fixed contact in its time-delay break contact connects, input end with controllable silicon and trigger circuit thereof after fixed contact in its time closing contact is connected with switch joins, the control regularly electronic timer motor of transfer power connects both ends of power, and the utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is an electrical block diagram of the present utility model;

Fig. 2 is the electrical block diagram of a kind of embodiment of the present utility model;

Fig. 3 is the electrical block diagram of the another kind of embodiment of the utility model;

Fig. 4 is the utility model controllable silicon and trigger circuit structural representation thereof.

According to Fig. 1, motor T _M1The electronic timer control convertible contacts group T that is driven _S1, it is used for regularly transfer power of control, and this electronic timer can be used mechanical timer.Convertible contacts group T _S1Moving contact and power supply one end join, fixed contact in its time-delay break contact connects extension line, input end with controllable silicon and trigger circuit thereof after fixed contact in its time closing contact is connected with K switch joins, and when K switch is closed, can realize the automatic transfer power of electric fan or electric-heating cooking utensil; K switch disconnects, and regularly power down function is then arranged.

According to Fig. 2, extension line 0 joins with another input end of thyristor gating circuit, and the output terminals A of controllable silicon and trigger circuit thereof and power end B connect the two ends of heating respectively, and K switch is with a time-delay break contact group T _S2Replace this contact sets T _S2By motor T _M2The electronic timer that is driven is controlled.Motor T _M2One termination power, the fixed contact in the time closing contact of the other end and convertible contacts group joins.

According to Fig. 3, extension line 0 joins with the input end of electric fan arrangements for speed regulation, and the output terminals A of thyristor gating circuit is connected on the main winding of fan motor.

According to Fig. 3, this is a controllable silicon commonly used and trigger circuit thereof.It is to be joined by potentiometer W, the resistance R of connecting with potentiometer W, resistance R and diac V, connect capacitor C simultaneously, diac and capacitor C are joined with bidirectional triode thyristor BCR trigger electrode and one end respectively again, and an end of the other end of bidirectional triode thyristor BCR and power supply joins.

During use, earlier electric fan arrangements for speed regulation or electric-heating cooking utensil are set, the time of setting power conversion, set the time of cutting off the power supply again, can open electric fan or electric-heating cooking utensil, the heating of electric fan arrangements for speed regulation or electric-heating cooking utensil is through convertible contacts group T _S1Back energized, electric fan or electric-heating cooking utensil work: after the power transfer time of setting arrives, convertible contacts group T _S1Action, its time closing contacting, the effect owing to potentiometer W makes the conducting of bidirectional triode thyristor BCR part to make power reduction, after the power-off time of setting arrives, time-delay break contact group T _S2Action, electric fan or electric-heating cooking utensil deenergization quit work.

The utility model is simple in structure, reliable operation, and cost is lower, has regularly transfer power, regularly the function of power cutoff.Very easy to use.
