The utility model has the advantages of reasonable structural design, high reliability, convenient and sanitary use, low cost, sensitive control, self-control rice cooking, congee cooking and soup decocting, complete function and favorable effect of energy saving, and is a new-generation multi-purpose electric rice cooker which is suitable for social need.

Description

Electronic energy-saving multi-purpose electrothermal rice cooker
The utility model relates to the electric energy-saving of a kind of electric cooker, particularly a kind of automatically-controlled multifunctional and uses electric cooker more.
At present, popularize the common electric cooker that uses, function of use is single, can only jump automatically when cooking and pull, and the water of cooking congee, stew soup and stew all can not be jumped automatically and be pulled, and overflows easily, needs the special messenger side to keep control, energy consumption height.International advanced Japan's " Xisi, famous beauty in the late Spring and Autumn Period's board " auto-electric cooker using pottery, it cooks, cooks congee, stews soup multiple functional automatically, but the control circuit structure is complicated, costs an arm and a leg, and the consumer is difficult to accept.
The purpose of this utility model is to provide a kind of improved electric energy-saving to use electric cooker for overcoming above-mentioned shortcoming of the prior art more, realizes cooking, cook congee, stewing soup and the energy-saving multifunctional automatic control, the convenient use.
The purpose of this utility model can realize by following measure: based on common electric cooker, increase the automatic control part, control circuit is made up of intensification control circuit, temperature sampling circuit, time control circuit, power-off control circuit and SCR control circuit.Connect power supply, intensification control circuit output signal makes the direct conducting of SCR control circuit, carry normal pressure power supply heat temperature raising to the electric cooker heat-generating disc, electric cooker is heated to boiling, temperature sampling circuit obtains sampled signal and send time control circuit, time control circuit outputs signal to the SCR control circuit, change the thyristor operating angle degree, the step-down heating, the output signal of time control circuit is ended intensification control circuit output signal simultaneously, step-down is selected by time control circuit heat time heating time, arrives point when selected heat time heating time, and power-off control circuit work is drawn back electric cooker heat-generating disc power switch and stopped heating.If cook, step-down is heated to meal and does, and more equally with common electric cooker jumps the insulation of pulling.
Principle of the present utility model and embodiment are provided by the following drawings:
Fig. 1 is the functional-block diagram that electric energy-saving is used electric cooker more.
Fig. 2 is an embodiment circuit diagram of the present utility model.
The utility model is described in further detail below with reference to accompanying drawing: with reference to Fig. 1, Fig. 2, K closes a switch 1, K 2, voltage-stabilized power supply provides power supply to control circuit, the IC of intensification control circuit 1The output positive potential is through resistance R 1Be coupled to IC 2, IC 2Be connected into positive-feedback circuit, IC 2The output positive potential is with IC 2The triode Q that output connects 1Conducting, relay J 1Adhesive, the controllable silicon TR of SCR control circuit 1The full angle conducting is directly carried normal pressure power supply heat temperature raising to heat-generating disc, and when electric cooker was heated to boiling point, vapor (steam) temperature made the thermistor R of temperature sampling circuit TResistance descends, IC 3With thermistor R TThe input terminal voltage that the connects height that edges up then, when being higher than reference voltage, IC 3Output drops to electronegative potential by original high potential, IC 3Output connect selector switch K 3, K 3Can select regularly to jump to pull or cook automatically, timing control circuit connects K 3, be provided with capacitor C 1And IC 4The fair attitude timing circuit of the list of forming, IC 4Input connects variable resistor R 3, adjust R 3IC is boiled the time in the resistance decision 3Output through K 3Be communicated with C 1The time, IC 3Output is reduced to electronegative potential, IC 4The output high potential is through diode D 2Make triode Q 2Conducting, Q 2Short circuit Q 1Base stage, Q 1End relay J 1Discharge, connect IC simultaneously 4The relay J of output 2Adhesive, controllable silicon TR 1Still be in conducting state, but the bilateral diode D of SCR control circuit 6Series resistance R 4, be added in D 6Voltage reduce controllable silicon TR 1The conducting angle diminish, send electricity to the heat-generating disc step-down, disobey and to hold in pot boiling and do not cause and overflow, cut down the consumption of energy, voltage is preferably reduced to 60～100V, if K 3Connect IC 3Output and C 2, IC 3The output electronegative potential, IC 5The output high potential is through diode D 1Make Q 2Conducting, Q 1End relay J 1Discharge, this signal makes relay J simultaneously 3Adhesive, controllable silicon TR 1The angle of flow diminishes, the step-down heating.
Power-off control circuit is provided with diode D 3Connect IC 2Output, diode D 4Connect IC 4Output, diode D 5Connect IC 5Output, D 3, D 4, D 5Form AND circuit, AND circuit connects ic chip 6Input, when the heating that heats up, the step-down of cooking heating or timing step-down are heated, AND circuit output high potential, IC 6Output is an electronegative potential, only arrives point in the time of regularly boiling, AND circuit output high potential, IC 6The output high potential, relay J 4Adhesive, controllable silicon TR 2Conducting, magnetic N action is the power switch K of electric cooker heat-generating disc 2Draw back, electric cooker stops heating.Relay J 1, J 2, J 3, J 4Preferably adopt light-sensitive realy.
In use, the K that closes a switch 1, K 2With selector switch K 3, cook congee in this way, stew soup to set up and boil the time, more can finish the program that boils of setting automatically.
The utility model reasonable in design is further improved the function of electric cooker, enlarges the automatic control scope of application, and control is sensitive, reliable operation, energy-saving effect is remarkable, can not cause excessive, clean hygiene, the cost cost of this product is low, can adapt to the consumer need of society, has good DEVELOPMENT PROSPECT.
