Abstract
The utility model relates to a multi-purpose electronic adjusting unit suitable for adjusting light, temperature, and speed of resistance type household electric appliances, which is composed of a luminescent indicating circuit, an RC phase shift circuit, a trigger diode, a bidirectional thyristor, an upper casing, a lower casing, etc. The potentiometer of the RC phase shift circuit adopts a straight slide potentiometer, and the upper casing is provided with an adjusting slotted hole. One end of the slotted hole is provided with a luminescent indicating hole, and the other end is provided with a switch. The utility model has the advantages of simple structure, small size, convenient hand operation, wide application range, etc., can be matched with a bed lamp, a pendant, an electric heater, an electric fan, etc., so as to achieve the goal of adjusting the light, the temperature, and the speed.
Description
The utility model relates to household electrical appliance control technique field.Be specially adapted to the speed governing of light modulation, temperature adjustment and the fan of some resistor-type electrical appliances, belong to the improvement of existing desk lamp dimmer.
At present, some resistor-type household electrical appliance that people use, in actual use, sometimes need to carry out light modulation to it, temperature adjustment or speed governing are as to the bulb light modulation, existing light modulation desk lamp, its rotary dimmer and desk lamp combine as a whole, but most of bedside lamp does not have the supporting with it use of independent dimmer, and this brings many inconvenience to the user, electric heaters such as some electric cups, immersion heater and for example, power is non-adjustable during use, does not have the independent thermosistor of adapted with it, also makes troubles to the user; And for example button step speed regulation or infrared remote control speed governing are generally adopted in the speed governing of fan, the former uses inconvenience, latter's complex structure, and cost is higher, wish to have a kind of matching used with it wired stepless speed adjusting gear for the people that use common electric fan, to satisfy people's requirement.
The purpose of this utility model provides a kind of simple in structure, easy to use, can with the supporting use of some resistor-type electrical appliances, the multipurpose electronic modulator that carries out light modulation, temperature adjustment or speed governing.
The utility model is achieved in that according to the bidirectional thyristor for regulating voltage principle, by luminous indicating circuit, compositions such as RC phase-shift circuit, diac and bidirectional triode thyristor, potentiometer in the described RC phase-shift circuit is a linear sliding potentiometer, adopting the purpose of linear sliding potentiometer is to make this modulator volume less, hand-held is convenient, make in the independent supporting use of resistor-type electrical appliance, for this reason, this modulator shell is made up of upper and lower casing, be provided with the regulation and control slotted eye on upper shell, this slotted eye one end is provided with luminous indicator hole, and the other end is provided with shift knob.The course of work of this electronic adjusting controller circuit is such: the resistance of linear sliding potentiometer is from large to small the time, voltage on the capacitor is except that discharging and recharging the phase shift, magnitude of voltage also changes from small to big, thereby the ON time of diac is moved forward gradually, capacitor discharges to the The Trigger of Bidirectional Triode Thyristor utmost point by diac, bidirectional triode thyristor is triggered and conducting, and conduction angle changes from small to big, thereby reach the purpose of silicon-controlled voltage regulation, and finally reach the purpose of light modulation to the resistor-type electrical appliance, temperature adjustment, speed governing.Light-emitting diode in the luminous indicating circuit is whether indication electrical appliance and power supply are connected, when being used for the bedside lamp use, light-emitting diode can show the position of modulator in the dark, is convenient to the user and finds modulator in the dark, when bulb is lightened gradually, electric current by light-emitting diode diminishes, extinguish gradually, when head of a bed bulb is dimmed when extinguishing gradually, then the electrorheological of light-emitting diode is big, brighten gradually, to show its position, behind the stopcock, light-emitting diode extinguishes.
The utlity model has simple in structure, volume is little, hand-held is convenient, applied widely, can with the resistor-type electricity with advantages such as the independent supporting uses of device.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is a profile schematic diagram of the present utility model;
Fig. 3 is the schematic top plan view of Fig. 2;
Referring to accompanying drawing, this multipurpose electronic modulator is by luminous indicating circuit, the RC phase-shift circuit, diac 7, bidirectional triode thyristor 8 and upper shell 11, lower house 12 compositions such as grade, luminous indicating circuit is to be made of resistance 2 and light-emitting diode 3, the RC phase-shift circuit is by resistance 4, linear sliding potentiometer 5 and electric capacity 6 constitute, on upper shell 11, be provided with regulation and control slotted eye 14, the key button 10 of linear sliding potentiometer 5 stretches out upper shell by slotted eye 14, end at slotted eye 14 has luminous indicator hole 15, the other end is provided with shift knob 9, this light-emitting diode 3 places in the luminous indicator hole 15, and switch 1 places the bottom of shift knob 9.According to instructions for use, can connect lead 13 respectively in the one or both ends of upper and lower casing.This multipurpose electronic modulator can with supporting uses such as resistor-type bedside lamp, pendent lamp, electric heater, electric fan, reach the purpose of light modulation, temperature adjustment, speed governing.
