Abstract

The utility model relates to an electronic stepless temperature adjusting energy saving electric stove, which is composed of a stove body, a heat generating and insulating part, and a stepless temperature adjusting circuit. An electric stove plate is arranged in a heat insulating member filled with heat insulating materials and is fixed in the short supporting hole of a stove case of the stove body through a central fixing bolt together with a supporting board; the stepless temperature adjusting circuit forms a trigger circuit through the series parallel connection of a resistor, a potentiometer, a capacitor, a bidirectional diode, a bidirectional thyristor, and a heating wire. The charging voltage of the capacitor can be changed and the turning and the conduction of the bidirectional diode can be controlled through rotating the potentiometer, so that the goal of the stepless temperature adjustment can be realized through controlling the conduction angle of the bidirectional thyristor.

Description

Electronic stepless temp. adjusting energy saving electric stove

Kitchen utensils under the electronics stepless temperature-regulating energy-saving electric stove are a kind of insulation, energy-saving electrothermic kitchen range.

Recent two grades or the third gear power conversion electric furnace that occurs, the gear shift transform power is regulated temperature as required, but because the power conversion is discontinuous, the switch gear shift is frequent, does not have the insulation measure again, so exist easy generation fault and the not high defective of the thermal efficiency.

In order to address the aforementioned drawbacks, designed a kind of electronics stepless temperature-regulating energy-saving electric stove, adopt electronics stepless temperature-regulating circuit to carry out evenly regulating continuously to the kitchen range temperature, with insulation material compression moulding heat preservation member,, improved the thermal efficiency to electric furnace pan garden week and bottom sealing.

The utility model is made up of stove, heat preservation part and stepless temperature-regulating circuit.Stove comprises kitchen range shell, supporting plate, long stent, two short supports, glue pin etc.The kitchen range shell is screwed by top board, header board, back plate and two blocks of side plates and surrounds.Two short support one ends and long stent are riveted into one, in addition end be screwed back plate at the kitchen range shell by time position on, the hole, garden of wearing the center fixation bolt is arranged by the frame end of drawing money on credit, the long stent two ends are screwed the left side at the kitchen range shell respectively, on the right plate, supporting plate is placed on length, on short the plane that is configured to, there is the hole, garden of wearing the center fixation bolt at the supporting plate center, kitchen range shell header board has the hole, two gardens and the hole, indicator lamp garden of dress potentiometer, two holes, garden that can put into electric furnace pan are arranged on the kitchen range shell top board, be eyes, plate has the hole, garden of installation insurance pipe and extracting power supply cord behind the kitchen range shell, 4 glue pin are fixed on below the right angle trigonometry iron plate of bottom, around side plate and the back plate right angle flanging is arranged, top board and header board are a plate punch forming, and make header board and the top between be converted into 120 ° of angles, there is flanging the header board termination, and the corresponding rigging screw hole that connects into the kitchen range shell is all arranged on all flangings.

Above-mentioned heat preservation partly comprises electric furnace pan, heating wire, heat preservation member, insulation filler etc., heat preservation member is pressed into garden box type with insulation material, there is the hole, garden of wearing the center fixation bolt at the center, garden box inner bottom part is covered with the insulation filler, electric furnace pan is placed on the filler of heat preservation member, pass heat preservation member by the center fixation bolt from electric furnace pan after, put into by the top board eyes, aim at hole, supporting plate garden, hole, short support garden is tightened to one with nut.

Above-mentioned stepless temperature-regulating circuit is by R ₁, RW ₁, C ₁, 2S ₁, SCR ₁And R ₂, RW ₂, C ₂, 2S ₂, SCR ₂After connection in series-parallel, constitute the potentiometer RW in circuits for triggering, the circuit respectively ₁And RW ₂Be installed on the kitchen range shell header board, other components and parts are welded in circuit board and are fixed in the kitchen range shell on the 20 long stent holes.

The utility model is because specialized designs has heat preservation member, putting into insulation filler, electric furnace pan in heat preservation member has heating wire, electric furnace pan to be put on the insulation filler of heat preservation member, make its bottom and sealed on every side, heat preservation and energy conservation effects improves a lot, and the stepless temperature-regulating principle to be example with a glance be described below referring to Fig. 4: connect alternating current 220V voltage, electricity is in circuit design R ₁＞＞DL ₁, heating wire DL ₁Do not work yet, have only RW ₁Rotate for a short time during to certain resistance, alternating current is through resistance R ₁, potentiometer RW ₁, to capacitor C ₁Begin charging, when the C1 both end voltage rises to bilateral diode 2S ₁During forward conduction, 2S ₁Conducting is also sent a pulse-triggered bidirectional triode thyristor SCR ₁Conducting, heating wire DL ₁Work.Work as current over-zero, SCR ₁Turn-off DL ₁Do not work, capacitor begins reverse charging, works as capacitor C ₁Both end voltage rises to bilateral diode 2S ₁During reverse-conducting, 2S ₁Conducting is also sent a pulse-triggered bidirectional triode thyristor SCR ₁Conducting, DL ₁Work again.Because circuits for triggering are operated in the alternating current circuit, therefore send a positive pulse and negative pulse respectively to controllable silicon SCR in positive and negative two half cycle symmetries ₁The control utmost point makes SCR ₁In positive and negative half cycle each conducting once, DL ₁Corresponding to SCR ₁Work during conducting.If increase RW ₁Resistance makes C ₁Charging has slowly postponed 2S ₁The turnover conducting just increases SCR constantly ₁Pilot angle, reduce the angle of flow, output voltage (electric current) is reduced.Otherwise, rotation RW ₁When resistance reduced, output voltage (electric current) raise, and had reached the effect of stepless temperature-regulating.Another temperature adjustment principle is the same identical.
