Description

Multifunctional attachment for electric rice pot

The utility model relates to a kind of electric cooker multi-functional control attachment device.

Along with the raising of people's living standard, electric cooker is also popularized day by day and is used, and its function is more and more." the electric cooker temperature control automatic blanking device " of Chinese patent application " 92229160.8 " is a kind of attachment device of electric cooker, has following meter function automatically, and energising is heated to uniform temperature but it needs earlier, and is influential to the rice quality; Also have by additional hopper add automatically water as " fully automatic electric cooker " of application number for " 87215054.2 ", it is switched on when adding water and cooks, in pot rice more after a little while, in the pot heating-up time fast and Mi Weineng fully absorbs water, cause the meal that cooks stiff or not yet done; Also some electric cooker can be realized wash water, discharges water, cook automatically, but their structural design and control circuit are all complicated, and cost is higher, is difficult to popularize.

The object of the present invention is to provide a kind of and common automatic electric rice cooker compatibility supporting, make its original function constant outside, also have long-time timing, automatically put rice, multi-functional electric cooker adapter such as absorb water and cook, uncap.

The utility model is realized its purpose as follows: the adapter bottom is provided with movable Mi Cangmen 2, is followed successively by meter storehouse 6, rice storehouse lid 5 on it, the electromagnet M outside the rice storehouse 6 ₁, M ₂Relative with

latch

1,3 respectively, latch 1 is stuck in movable Mi Cangmen 2 times, and latch 3 is pressed on the spring 4 of uncapping, and circuit control panel 7 and timing controlled chamber 9 are located at the adapter outside.

The adapter circuit comprises regularly order executive circuit: the Q of integrated package CD4060 ₁₄End joins differential circuit C with the Cp end of CD4017 ₁, R ₁And C ₂, R ₂Connect the R input of CD4060 and 4017 respectively, R input and the Q of CD4060 ₁₄Also be connected to diode D between end ₁, the output Q of CD4017 ₀～Q ₃End is connected to the trigger end of K switch a～Kd of analog switch CD4066 respectively, and each switch one end of CD4066 is by resistance R s ₁ Pin 9 ends that reach capacitor C s and CD4060 join, and the other end is through variable resistor W ₁～W ₃Join the Q of CD4017 with pin one 0 end of CD4060 ₂End is by diode D ₄And K switch ₂, Q ₃End is by diode D ₅All with triode BG ₂Base stage join Q ₂End also is connected to triode BG ₁Base stage, BG ₁, BG ₂Colelctor electrode respectively through electromagnet M ₁, relay J and power positive end join.Circuit comprises that also pin two, 6 ends and the thermistor Rt of automatic lid closing/opening circuit: NE555 join output pin 3 ends and triode BG ₃Base stage join BG ₃Colelctor electrode through electromagnet M ₂Join with power positive end.

The utility model has the advantages that: simple in structure, cost is low, need not change the structure of former electric cooker and adapted; Can regularly also put rice automatically for a long time, and just energising intensification after rice is fully absorbed water, the rice that cooks is soft good to eat; But cook congee or automatic lid closing/opening also during soup.

Embodiment further specifies the utility model below in conjunction with accompanying drawing:

Fig. 1 is structure of the present utility model and uses allocation plan.

Fig. 2 is a circuit diagram of the present utility model.

The positive pole of dc source E is through diode D in the circuit ₉Diode D with three-terminal voltage-stabilizing integrated package 7809 outputs ₈Negative pole end joins, linked switch K ₁Control the break-make of AC power and dc source E simultaneously; Electromagnet M ₁, M ₂, relay J all is parallel with diode D respectively ₇, D ₁₂, D ₆Microswitch AN one end simultaneously with the Q of CD4060 ₁₄End and the Cp of CD4017 hold and join, the other end with in parallel after be connected to the resistance R of positive source ₃And capacitor C ₃Join; R input and the Q of CD4017 ₄Be connected to diode D between end ₃Each switch one end among the CD4066 all is connected to the variable resistor that pin one 0 end with CD4060 joins, pin one 1 end and the resistance R s of CD4060 ₁An end between also be connected to resistance R _MAdapter can be made into the product of all size, and its external form is placed on during use on the electric cooker like the electric cooker food steamer, is connected with lead with it and controls by relay J.

During use, the rice wash clean is placed in the rice storehouse 6 of adapter, configures down a rice time, meter absorbent time, the line 8 and press K switch of connecting with the mains ₁And electric cooker switch.At this moment, through C ₁R ₁And C ₂R ₂Direct impulse behind the differential makes CD4060 and CD4017 zero clearing, Q respectively ₀The output high level makes the K switch a among the CD4066 connect variable resistor W ₁Insert in the CD4060 oscillation circuit, 14 grades of binary string linage-counters in the CD4060 promptly begin counting and timing.After timing arrives, Q ₁₄The output high level signal, this level is on the one hand through diode D ₁The R end of input CD4060 makes Q ₁₄The current potential step-down is with making Q up to the Cp of CD4017 end ₀Become low level, Q ₁Export high level, make K switch a disconnection, the Kb closure of CD4066, W ₁Insert oscillating circuit once more, regularly, K switch a, Kb all meet variable resistor W once more ₁, twice timing can improve timing accuracy, realizes regularly long-time.Timing arrives, Q ₁₄Export high level again, the Q of CD4017 ₁By high step-down, Q ₂The output high level makes BG ₁Conducting, electromagnet M ₁Electric Mi Cangmen 2 opens with latch 1 adhesive, Mi Zidong enters in the electric cooker, simultaneously K switch b disconnect, the Kc closure, a rice suction timing begins.Time one arrives, and the operating principle of CD4060 and CD4017 is the same, Q ₂By high level step-down, Q ₃The output high level, the one tunnel through D ₅, R ₅Make BG ₂Conducting, relay J get electronic work, connect the electric cooker power supply and cook, and another road makes K switch c disconnection, Kd closure, begins to cook regularly.Setting-up time arrives, the Q of CD4060 ₁₄End is exported high level, the Q of CD4017 again ₃End is by high level step-down level, BG ₂End, J control disconnects the electric cooker power supply.

Cook congee or during soup, K switch ₃Close, thermistor Rt is greater than 680 Europe during normal temperature, and the pin 3 of NE555 is output as 0 volt, when kettle temperature near or when reaching 100 ℃, Rt becomes about 10 Europe, NE555 pin 3 output high level make triode BG ₃Conducting, electromagnet M ₂The electronic adhesive latch 3 of doing, the spring 4 of uncapping of former compression is resetted caping is opened, water can be not excessive; Do not need long-time regularly once to get final product by microswitch AN following meter the time; In the time of need not absorbing water regularly, can press K switch ₂In the long-time regularly following meter process, have a power failure if alternating current is unexpected, then dc source E can keep power supply, makes timing and order unaffected.
