Abstract
The utility model relates to a thermoregulator for electric radiators and heaters. After a mechanical timer, a hand switch, a bidirectional thyristor, diodes, capacitors, an LED display and an inductor are connected in series in turn, both ends of the thermoregulator is connected to the input end of a power supply. A potentiometer of a thyristor triggering circuit adopts a potentiometer without a switch. The utility model is capable of realizing small power to large power, and has the advantages of adjustable large power, good continuity, luminous display function, complete functions, reasonable design and good performance.
Description
The utility model relates to a kind of control device in the electricity field, particularly a kind of electrical equipment adjustment control.
Chinese patent 94227211 provides a kind of " controllable silicon stepping thermosistor "; its circuit comprises circuits for triggering, bidirectional triode thyristor and silicon controlled rectifier protecting circuit; wherein circuits for triggering are made of band switch, series resistance, charging capacitor and bilateral diode; in circuit, be connected with voltmeter; show pressure regulation voltage intuitive and convenient; but the band switch pressure regulation, poor continuity, no timing means, function singleness.
The purpose of the utility model aim to provide a kind of realize from small-power to high-power adjustable, continuity good, have timing, luminous Presentation Function, electricity multiple functional, that adaptability is good warm up the electric heating appliance thermosistor.
Technical solution of the present utility model is: the warm electric heating appliance temperature-regulating device of this electricity has mechanical timer, hand switch, bidirectional triode thyristor, thyristor gating circuit, diode, electric capacity, light emitting diode indicator, inductor, and after mechanical timer, hand switch, bidirectional triode thyristor, diode and electric capacity, light emitting diode indicator, inductor were connected successively, two ends were connected in input supply terminal.After thyristor gating circuit adopts resistance, potentiometer, capacitances in series, two ends are connected to the positive negative electrode of bidirectional triode thyristor, the mid point that is connected of potentiometer and electric capacity, by being connected in the control utmost point of bidirectional triode thyristor behind the bilateral diode, potentiometer adopts the not potentiometer of belt switch.
The utility model is compared with prior art, has stepless temperature-regulating, regulate the good characteristics of continuity, particularly potentiometer adopts the not potentiometer of belt switch, it is little that this has just overcome the sort of in the past potentiometer with switch rated current, burn out easily and cause the whole anti-revisionist shortcoming of damaging, the utility model is provided with potentiometer and switch respectively, help strengthening reliability of products and greatly increase the service life, the utlity model has mechanical timer simultaneously, also has light emitting diode indicator, like this, make obtain giving the automatic control of establishing the service time of electrical equipment, improved the automatic control degree of product.Luminous demonstration makes adjustment, voltage-regulation become directly perceived, simple to operate, be convenient to grasp, so the utility model is multiple functional, function admirable, reasonable in design.Can be widely used in electric heater, electric chafing dish, electric frying pan and other electrical equipment, of many uses.
Fig. 1 is the utility model circuit structure diagram.
