Description

The timing adjustable electric cooking stove

One, technical field

The utility model relates to a kind of electric furnace, but particularly a kind of adjustable electric cooking stove with timing function.

Two, background technology

The electric furnace that can see on the market at present roughly has two kinds: a kind of is traditional fire clay stone or metal plate for standing a stove on as a precaution against fire electric furnace, has only an electric furnace heating wire, and this electric furnace can not temperature adjustment.But another kind is an adjustable electric cooking stove of making stone or metal plate for standing a stove on as a precaution against fire of fire-resistant asbestic blanket, and two electric furnace heating wires have three kinds of power for selecting for use.This furnace power shelves regularly do not start default and the setting of regularly boiling very little, and it is convenient inadequately to use.Simultaneously, because the high temperature of electric furnace heating wire itself, make the power lead that is attached thereto or bolt, the rapid oxidation corrosion of nut, it is very difficult to change electric furnace heating wire.

Three, summary of the invention

The purpose of this utility model provides that a kind of power shelves are many, band regularly starts default and the setting, easy to use of regularly boiling, and can avoid the timing adjustable electric cooking stove of the power lead that is connected with electric furnace heating wire or bolt, nut oxidation corrosion.

Timing adjustable electric cooking stove of the present utility model comprises body of heater, is placed on the fire resistant heat preserving insulating materials in the body of heater, electric furnace heating wire is characterized in that also comprising contactor, electric chronograph, universal seclector and long distance compression type electric furnace heating wire termination, and electric furnace heating wire increases to three; Its circuit connects as follows: power firestreak S is connected with contacts of contactor K, ground wire is connected with contacts of contactor J, zero line O is connected with contacts of contactor I, contacts of contactor K is connected with the coil W of electric chronograph with contacts of contactor I, the electric chronograph contact R is connected with contactor coil tap P, electric chronograph contact T is connected with contactor coil tap Q, contacts of contactor N is connected with the universal seclector contact A, contacts of contactor L is connected with universal seclector contact B, contacts of contactor M is connected with body of heater, universal seclector contact A and universal seclector contact C, E connects, universal seclector contact B and universal seclector contact F, G, H connects, universal seclector contact a is connected with termination tap a, universal seclector contact b is connected with termination tap b, universal seclector contact c is connected with termination tap c, universal seclector contact e is connected with termination tap e, universal seclector contact f is connected with termination tap f, universal seclector contact D is connected with universal seclector contact c, the two ends of thermistor respectively with universal seclector contact d, e connects, the two ends of low-temperature furnace silk respectively with termination tap a, b connects, in warm electric furnace heating wire two ends respectively with termination tap b, e connects, the two ends of high-temperature electric resistance furnace silk respectively with termination tap c, f connects, the two ends of portable lamp respectively with the universal seclector contact A, g connects, the insulation lamp two ends respectively with the universal seclector contact A, h connects, the two ends of contactor indicator lamp respectively with the universal seclector contact A, B connects.

Timing adjustable electric cooking stove operation principle of the present utility model is such: power line is connected with contactor after entering body of heater, zero line is connected with electric chronograph before entering contactor coil, the output of contactor is connected with universal seclector, and power supply enters electric furnace heating wire through after the distribution of universal seclector by long distance compression type electric furnace heating wire termination.When timer connection contactor coil, the contacts of contactor closure, electric furnace is started working.When the timer arrival designated time, coil blackout, contacts of contactor is open, and electric furnace quits work.

Electric furnace heating wire is increased to three, and the gear of electric furnace rises to seven, satisfy variously in the cooking fry in shallow oil, explode, steam, boil, braised, stewing, stir-fry is to the needs of the duration and degree of heating.

The utility model is transformed the wheel of the card in traditional universal seclector, and several card wheels are set, and these card wheels are being controlled the folding of contact, can accomplish continuous folding.

Use electric chronograph, can accomplish to preengage start-up time and predetermined boiling the time.The utility model adopts five contact contactors, and four contacts wherein are divided into two groups, and as live wire and zero line, another contact is used as ground wire.

Long distance compression type electric furnace heating wire termination comprises five groups of single terminations, all is installed on the ceramic insulation heat dissipation base.Each termination has a chassis, and long distance is pressed tongue and the two pairs of bolts, nut.The power line of drawing from universal seclector is connected with one of them bolt, and with fixed by nut, electric furnace heating wire is then pressed tongue tightly to push down by long distance on another bolt.Because long distance is pressed tongue and the good thermolysis of ceramic base, and the heat of electric furnace heating wire is distributed rapidly, cross thermal oxide thereby bolt, nut are unlikely before passing to bolt, nut.So both change electric furnace heating wire easily, prolonged the life-span of electric furnace heating wire again greatly.

As required, stone or metal plate for standing a stove on as a precaution against fire also can be designed to flat, pan cooked food easy to use.

Timing adjustable electric cooking stove of the present utility model safety and sanitation, thermal efficiency height, the power and energy saving, the electric furnace heating wire long service life can also be preset start-up time as required and boil the time, and both convenient the use prevents burnt food again.
