Control section is described in this scheme: end heater H 2, integrated temperature controller, side heater H 1, Thermal Cutoffs RF1 and functional select switch S7 series connection, functional select switch S7 is a hilted broadsword three switches, common port is connected with power supply, wherein an end and the 4th diode D4 series connection entry loop, the other end directly inserts the loop, and the 3rd end is empty; The 5th button S5 is in parallel with side heater H 1; Relay control normal open switch is in parallel with side heater H 1; Relay drives the loop: after the control section parallel connection of the 6th button S6 and relay R L, in parallel after connecting with the 11 resistance R the 11, the 13 resistance R 13, the 3rd diode D3 again with electric capacity, in parallel with the series circuit of the 13 resistance R 13 with the 11 resistance R 11 after the tenth resistance R 10 is connected with the 12 resistance R 12, relay circuit is in parallel with end heater H 2.Insulation lamp LED1 connects in parallel with side heater H 1 behind the resistance, and beginning lamp LED4 connects in parallel with end heater H 2 behind the resistance.
Working method: plug in, interior pot is put into the integrated temperature controller in shell back contact with the bottom of pot and be depressed, place the 3rd switch S 3 of the temperature controller W1 below of integrated temperature controller to be pressed, internal circuit connection (finish like this pot detect function).
Grade electric cooker enters keeping warm mode automatically to cooking to stir functional select switch S7 (being provided with three kinds of functions in this electric cooker: close, cook congee, cook), after pressing the 5th button S5, side heater H 1 is by short circuit, heater H 2 two ends dividing potential drops in the end become big relay circuit and start working, the adhesive of relay normally open switch, relay is in hold mode.End heater H 2 is started working, and the lamp of cooking is lighted, the beginning of cooking.
When reaching the control temperature of temperature controller W1, the cooking bottom temperature of interior pot (represents that meal is cooked when cooking bottom temperature surpasses the control temperature of temperature controller W1), temperature controller W1 disconnects relay circuit and has a power failure, relay normally open switch opens, electric cooker enter keeping warm mode automatically.Will enter keeping warm mode and can directly press the 6th button S6 in the process of cooking, electric cooker enters keeping warm mode.
Embodiment two:
Consult Fig. 2, in the present embodiment, button in parallel on the side heater H 1 comprises button of cooking parallel with one another (the first button S1) and the button of cooking congee (the second button S2), and indicator lamp in parallel is in series with the 21 diode D21 for insulation lamp LED1 on the described button of cooking; Control relay circuit in parallel on the end heater H 2, the button in the control relay circuit is insulation button (the 4th button S4), indicator lamp in parallel comprises cook the lamp LED3 and the lamp LED2 that cooks congee in parallel with control relay circuit.Have simultaneously and cook and gruel boiling function, and cost is lower.
Adopt the microswitch control method, be provided with three microswitches (the first button S1, the second button S2, the 4th button S4) in the system and be used for realizing different functions.
Control section is described in this scheme: side heater H 1, integrated temperature controller, end heater H 2 are connected with electric current fuse RF1.It is in parallel in parallel after the first button S1 connects with the 21 diode D21 with side heater H 1 with the normal open switch RLC of relay R L, the second button S2 connects with the 22 diode D22 with the normal open switch RL1C parallel connection of relay R L1, integral body is in parallel with side heater H 1, and is in parallel with side heater H 1 after insulation lamp LED1 connects with the 9th resistance R 9.Relay drives loop I and connects with the 4th button S4 with relay driving loop II is in parallel, and is whole in parallel with end heater H 2.Relay drives normally closed switch, relay R L control side, the 4th resistance R 4, the 6th resistance R 6 of loop I, relay R L1 and connects with the first diode D1, in parallel after first resistance R 1,3 series connection of the 3rd resistance R with the series circuit of second resistance R 2 and the 4th resistance R 4, the lamp LED2 that cooks congee connects in parallel with electrochemical capacitor with resistance, electrochemical capacitor and relay, second resistance R 2, the 4th resistance R 4 are in parallel.Relay drives normally closed switch, relay R L1 control side, the 6th resistance R 6, the 8th resistance R 8 of loop II, relay R L and connects with the second diode D2, in parallel after the 6th resistance R 6,8 series connection of the 8th resistance R with the series circuit of the 5th resistance R 5 and the 7th resistance R 7, the lamp LED3 that the cooks back of connecting with resistance is in parallel with electrochemical capacitor, and electrochemical capacitor and relay, the 6th resistance R 6, the 8th resistance R 8 are in parallel.
Working method: plug in, with interior pot put into the integrated temperature controller in shell back with pot the bottom contact and be depressed, place the 3rd switch S 3 of the temperature controller W1 below of integrated temperature controller to be pressed, internal circuit is connected (finish pot like this and detect function), and electric cooker enters keeping warm mode automatically.
After pressing the first button S1, side heater H 1 is by short circuit, heater H 2 two ends dividing potential drops in the end become big, because the first button S1 connects with diode D2, so relay drives loop I work, relay R L normally closed switch is opened, and the normal open switch closing relay is in hold mode, and the start working lamp LED3 that cooks of end heater H 2 lights.
When reaching the control temperature of temperature controller W1, the cooking bottom temperature of interior pot (represents that meal is cooked when cooking bottom temperature surpasses the control temperature of integrated temperature controller), temperature controller W1 disconnects relay circuit and has a power failure, relay normally open switch opens, electric cooker enter keeping warm mode automatically.Will enter keeping warm mode and can directly press the 4th button S4 in the process of cooking, electric cooker enters keeping warm mode.
Press the second button S2, side heater H1 is by short circuit, it is big that heater two ends, end dividing potential drop becomes, because the second button S2 connects with diode D22, so relay drives the working relay RL1 normally closed switch of loop II and opens, the normal open switch closure, relay is in hold mode, end heater H 2 is started working, and the lamp LED2 that cooks congee (cook congee or steam) lights.Under this state, because sealed in the power reduction of the first diode D1 so end heater in the major loop, the requirement that is fit to cook congee, electric cooker can not closed automatically during this state, therefore when congee is cooked, need manually close, press insulation key (the 4th button S4) when closing and enter keeping warm mode.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
