4, after meal is cooked, the automatic tripping of temperature detect switch (TDS), muff heater 102 is started to work；Heat insulation work electric current, by electricity One end of source terminal 11 is through knob timer 104, muff heater 102, then through thyristor 105, cook heater 101 and power supply The other end of terminal 11 is formed into a loop；Muff heater 102 heats simultaneously with heater 101 of cooking at this time, realizes electric cooker Heat insulation work.

5, disconnected after the reset of knob timer 104, operating current on muff heater 102 and thyristor 105 and The control electric current of thyristor 105 disconnects, and muff heater 102, heater 101 of cooking stop heating work.

As shown in Fig. 6, Figure 10, Figure 13, Figure 14, electric cooker is cooked congee process:

1, power supply terminal 11 powers on, and presses temperature detect switch (TDS) 103, twists knob timer 104.

2, knob timer 104 resets in work, when timing contact A4012 is connected to power supply, realizes that high-power control is boiled Meal heater 101 works.

3, knob timer 104 continues to reset work, when timing contact B4013 is connected to power supply, realizes small-power control Heater 101 of cooking work.

4, in heating process of cooking congee, by the point identification 1043 on knob timer 104, it is directed toward corresponding capacity mark Know 1042, is arranged after high-power heating boils congee, quickly enters the state of low-power heating automatically, reach and more preferably heat Effect.

5, according to the numerical value of heating capacity, by the way that functional switch B501, connection control resistance B107 or control electricity is arranged C108 is hindered, control is cooked, and heater 101 is high-power or low-power heating, realizes more preferably heating effect.

6, it is disconnected after the reset of knob timer 104, the operating current and control electric current on thyristor 105 disconnect, and cook Heater 101 stops heating work.

As shown in Fig. 7, Figure 10, Figure 11, Figure 12, the electric cooker time reservation course of work:

1, power supply terminal 11 powers on, and presses temperature detect switch (TDS) 103, twists knob timer 104.

2, when the connection elastic slice 4014 and timing contact A4012 on knob piece 401 is contacted, due to timing contact A4012 It is set as neutral gear, the control electrode of thyristor 105 does not trigger and control voltage, and thyristor 105 is not turned on, and cooks heater 101 not Work.

3, when the connection elastic slice 4014 and timing contact B4013 on knob piece 401 is contacted, timing contact B4013 passes through Control resistance A106, bilateral diode 109 are connected with the control electrode of thyristor 105, and the control electrode of thyristor 105 is triggered And control voltage, thyristor 105 are connected, heater 101 of cooking work.

4, knob timer 104 resets in work, and the connection elastic slice 4014 on knob piece 401 is first connected to timing contact A4012, then it is connected to timing contact B4013, to realize the effect of electric cooker time reservation work.

Further introduction is made to the present invention above, control device of the present invention can be applied not only to electric cooker, can also To be applied on other electric heaters.The core for the principle of the present invention that the above embodiments are only used to help understand is thought Think, for those of ordinary skill in the art, according to the thought of the present invention, has in specific embodiments and applications Change place, in conclusion the contents of this specification are not to be construed as limiting the invention.
