Abstract
The utility model relates to an energy saving voltage regulator for a household electric heater of saving household electric heater energy. The regulator is composed of a housing, a circuit board fixed in the housing, a relay, a thyristor and a heat radiating fin. The inner circuit is composed of a protecting circuit, a pressure reducing circuit, a bridge rectifier, a voltage regulating circuit, a pulsed triggering circuit, a thyristor circuit and a display circuit. The energy saving voltage regulator can avoid the arc light generated by a contact switch working on and overheated influence because of oversize current, last the service life of the electric heater, and regulate and control heating temperature conveniently to save energy. The regulator has small size, light weight, large capacitance, reliable operation, etc., and can be used in thermoregulation, constant temperature and light modulation as household loading circuit.
Description
The utility model relates to a kind of energy-conservation voltage regulator of the energy-conservation domestic electric heater of family's electric heating appliance that is used for.
Along with the raising of development in science and technology and living standards of the people, home electrical heaters such as electric heater, roaster, resistance furnace, electric chafing dish have been come into huge numbers of families, and As time goes on its use will be more and more general.Yet existing various electric heaters all adopt the work of contact switch type, with staged power supply temperature adjustment.The shortcoming one of this kind work, method of temperature control is that operating current is big, and contact switch is easily by arcing and overheated and influence useful life; The 2nd, arbitrarily temperature adjustment, result of use can not be satisfactory.
Task of the present utility model is to provide a kind of domestic electric heater energy-conservation voltage regulator, utilize it can avoid arc light that contact switch when work produce and because of the big and overheated influence of electric current, prolong electric heater useful life, and can easily and flexibly electric heater be regulated and control to needed temperature, reach purpose energy-conservation and easy to use.
The utility model is to realize like this.It is made up of shell and dress wiring board, relay, controllable silicon and fin within it, and the front of shell (card) is equipped with voltmeter, fuse and indicator light, and two utmost points and three pole sockets are equipped with in the back.Self-contained circuit is made of protective circuit, reduction voltage circuit, bridge rectifier, voltage stabilizing circuit, pulsed triggering circuit, ghyristor circuit and display circuit, and wherein, protective circuit is by input fuse FU

3On obtain removing to trigger controllable silicon similar in appearance to the pulse voltage of sawtooth waveforms; Change the resistance of potentiometer Rw with hand, that is change the burst length and change the silicon controlled output voltage, thereby reach the effect of temperature-controlling energy-saving.
During use, in the power-line plug insertion supply socket with this energy-conservation voltage regulator, again the electrical equipment that will use is inserted on the socket of this voltage regulator back.Then, clockwise shearing potentiometer Rw, hear " " one, power supply indicator is bright, shows that voltage regulator works.At this moment, can twist Rw, the pointer of voltmeter MC is indicated to till the required magnitude of voltage.If the green indicating lamp of voltage regulator is also bright when start, illustrate that then supply socket phase line and zero line that voltage regulator is used connect instead, should correct one's mistakes to guarantee Electrical Safety.
Major advantage of the present utility model is: (1) adjusts voltage with the size of potentiometer control impuls, does not have contact switch, has avoided arc light and switch because of the big and overheated influence of electric current, can prolong electric heater useful life; (2) with the mode temperature adjustment of stepless debugging, save electricity can easily electric heater be regulated and control to temperature required.The energy-conservation voltage regulator of this kind can work alone, and is not subjected to the control of load temperature, and it also has characteristics such as volume is little, in light weight, capacity is big, reliable, can be used as the usefulness of family's resistive load electrical equipment temperature adjustment, constant temperature, light modulation.
