Description

Energy-conservation noiseless adjustable electric stove

The utility model relates to a kind of adjustable noiseless energy-saving electric stove of being made up of integrator, bidirectional triode thyristor.

At present, along with the development of energy industry.The use amount of family expenses electric stove is cumulative, and it is energy-conservation, pollution-free, easy and simple to handle with it, and enters people family gradually.The controllable silicon electric stove regulating system of Chu Xianing is exactly to require transform power with control stove silk temperature according to the different cookings in recent years, realize to food steaming, function such as boil, fry in shallow oil, explode.But sort circuit is because what adopt is phase-shift trigger circuit, can make that the electrical network output waveform degenerates, power factor reduces, and can produce abundant high order harmonic and electronic equipment and AM receiver are produced disturb.And kitchen range do not have the insulation measure again, so that ubiquity the thermal efficiency is low, easily produce defectives such as fault.

The purpose of this utility model is to provide a kind of simple in structure, adjustable noiseless SCR control electric stove that cost is low, by the resistance of regulator potentiometer, changes the output frequency of load, to realize stepless temperature-regulating.

The purpose of this utility model is achieved in that the energy-conservation noiseless adjustable electric stove by kitchen range is stopped, heat preservation spare and stepless temperature-regulating circuit are formed.The shape of its heat preservation spare is garden camber or plane according to the bottom shape of stone or metal plate for standing a stove on as a precaution against fire, material by Stone and perlite are composited.Add the stepless temperature-regulating circuit by integrator, bidirectional triode thyristor, resistance, electric capacity, resistance wire constitute the SCR control circuit through connection in series-parallel.Input 4 and semifixed resistor R at integrator ₂, R ₃Between be in series with adjustable potentiometer R _P1, regulate R _P1Resistance, can in load, obtain the complete ripple that just drips by controllable silicon BTA at output 6, can adjust output quantity easily again.

The utility model is owing to adopted the heat-insulating material heat insulation, that heat-insulating property is good. and the more common electric stove of heat preservation and energy conservation effects improves more than 20%.And the stepless temperature-regulating circuit makes the temperature regulating range of electric stove be wider than phase-shift circuit, and does not have waveform and disturb, and has reached economize on electricity, insulation, the purpose of temperature adjustment continuously.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a front section view of the present utility model.

Fig. 2 is an electrical schematic diagram of the present utility model.

In Fig. 1, shell 16 is made for stainless steel material, header board has indicator lamp 13,6 in the hole, garden of press button 14 and power adjusting knob 15, the middle part has two kitchen range eyes, and electric furnace pan 12 is contained in kitchen range in the eyes, and the bottom of electric furnace pan 12 is provided with heat preservation member 11, the shape of heat preservation member 11 is garden camber or plane according to stone or metal plate for standing a stove on as a precaution against fire 12 bottom shapes, insulation material by Stone and perlite are composited, and it makes the heat radiation and the heat conduction loss of two heating chassis and sidepiece reduce to minimum point.

In Fig. 2, provided the schematic diagram of energy-conservation noiseless adjustable electric stove.Integrator IC ₁In a plurality of inputs and a plurality of output are arranged, the contact 4,5 of input is connected to adjustable potentiometer R _P1With the correction resistance R ₂, R ₃, a direct current power filtering capacitor C connects between input 2 and ground wire ₁, input 7 is "+" utmost point input, and output 1 is a sawtooth waveforms amplifier output point, and a reference resistance R has connected between output point 3 and the ground wire ₁, R ₁Be serially connected with sawtooth waveforms charging capacitor C with power input ₂, output point 6 is a pulse output end, connects bidirectional triode thyristor BTA, output 8 and load R _LBetween pulse of serial connection output width adjusting resistance R ₄, the size of its resistance influences load R _LOn average voltage.When connection 220V voltage, the K that closes a switch, electric current is by indicator lamp D ₁With rectifier D ₂, step-down supplying resistance R ₅With input 5, this moment, controllable silicon BTA was for logical, load R _LDo not work, regulate resistance R _P1, make input V ₄Voltage is less than reference voltage V ₃, output 6 output control signals make the controllable silicon conducting, obtain 100% power in the load.Work as R _P1Greater than R ₁The time, the current potential of output 3 is higher than V ₄, this moment, output 6 ended, when need only needing to regulate R greater than 0 during less than 100 a certain power _P1Resistance slightly less than R ₁, can obtain V ₃Be slightly less than V ₄, can obtain the power of 1-100% in the load, thereby realize stepless temperature-regulating.
