Abstract

The utility model relates to a full-automatic temperature controlled thermal insulation electric rice cooker, which characterized in that a timer, a temperature control circuit for automatically reducing heat and a porridge-cooking function switch are additionally arranged on an ordinary electric rice cooker comprising a cooker body, a heating element RR, a magnetic steel temperature limiter, a thermophore. The temperature control circuit for automatically reducing heat is connected in series with the porridge-cooking function switch, and then is connected with the magnetic steel temperature limiter and the thermophore in parallel. The parallel loop is connected in series with the timer and the heating element RR. As the ingenious combination of the timer, the magnetic steel temperature limiter, the temperature control circuit for automatically reducing heat and the thermophore controls the process of cooking rice, porridge and soups and thermal insulation, etc. with the electric rice cooker, the utility model has miscellaneous functions such as prevention against overflow, automatical starting, timing shutdown, etc. and has the advantage of low cost.

Description

The full-automatic heat-preservation electric rice cooker of temperature control

The utility model relates to a kind of full-automatic heat-preservation electric rice cooker of temperature control that temperature control reduces caloric value and timing function automatically that has.

Electric cooker one class is a function singleness in the market, can only cook, and can not cook congee, boil soup, easily overflows, and uses inconvenience, and is another kind of by computer control, but price is expensive, is difficult for being accepted by consumers in general.

The utility model purpose is for overcoming the shortcoming of existing electric cooker, providing a kind of function many, low-cost again temperature control automatic heat preserving electric cooker.

The technical solution of the utility model so realizes, at a kind of pot body that includes, heater element, set up timer on the common heat-preservation electric rice cooker of magnetic steel temperature limiter, warmer, temperature control reduces heat circuit and gruel boiling function switch automatically, temperature control reduces the heat circuit back of connecting with the switch of cooking congee automatically and is in parallel with magnetic steel temperature limiter and warmer, and this shunt circuit and timer and heater element are in series.Temperature control reduces the caloric value circuit automatically and is composed in parallel with reducing the caloric value element by temperature-sensitive element, and the timer of setting up can adopt dissimilar, can adopt electronic type or motor type timer, can also be single timer or dual timer.Temperature-sensitive element can be selected with bimetallic temperature sensitive switch or thermistor or magnetic steel temperature limiter, reduce the caloric value element and can maybe can adopt resistance or diode with heating element heater, also can adopt and vary with temperature temperature sensitive switch or the time pause switch that cut-offs, reduce the step-down amplitude of caloric value element and be interrupted all can ask as required heat time heating time and regulate, reach the optimum temperature cooking, the purpose of insulation to reach different food.For easily manufactured, but also fixed amplitude and at interval.

The utility model embodiment elaborates in conjunction with the accompanying drawings.

Fig. 1 is the circuit diagram of the utility model embodiment 1;

Fig. 2 is the circuit diagram of the utility model embodiment 2;

Fig. 3 is the circuit diagram of the utility model embodiment 3;

Fig. 4 is the circuit diagram of the utility model embodiment 4;

Embodiment 1:

By shown in Figure 1, D1 adopts dual timer (my patent, the patent No. is: 91215445.4), can preset to set regularly to start and close with timing, temperature-sensitive element K31 adopts butterfly shaped dual metal sheet, its break-off signal is between 85 °～98 ℃, reduce the caloric value element and be composed in series, when cooking, press magnetic steel temperature limiter K switch 1 by heating element heater A1 and diode B1, be incubated by warmer K2 then, can be incubated for a long time like this, press gruel boiling function K switch 4 when cooking congee, when the temperature of cooking congee arrives 98 ℃, temperature-sensitive element K31 disconnects, the body temperature degree is higher than the warmer break-off signal because stew this moment, so the warmer switch disconnects, electric cooker is by reducing heater element A1, diode B1 connects with heater element to heat and reaches the anti-overflow of cooking congee, and reduces the requirement of caloric value.

Embodiment 2

By shown in Figure 2, timer 02 adopts single timer that regularly turn-offs, temperature-sensitive element adopts thermistor K32, reduce the caloric value element and adopt adjustable resistance A2, to reach the purpose of adjustable step-down, can according to food what, kind is regulated and voltage after RR connects, thereby can regulate the high low amplitude of reduction caloric value.Also resistance can be fixed.

Embodiment 3:

By shown in Figure 3, timer adopts electronic timer D3, and temperature-sensitive element adopts spiral shell shape bimetal leaf K31, reduces the employing of caloric value element and varies with temperature the bimetal release A3 that cut-offs, and it is fixed on pot body.The K4 that closes when cooking congee, at this moment, bimetal release A3 changes control RR according to pot body temperature degree and heats at interval to reach and reduce caloric value and prevent that congee soup etc. from overflowing.

Embodiment 4:

By shown in Figure 4, different is to reduce the caloric value element to adopt time pause switch A4 with embodiment 1,3, close the caloric value of controlling RR when opening by in time the time, reach and reduce the purpose that adds heat, A4 can adopt independent clock switch, also can make one with timer, its time interval can be regulated, and can also fix.

As seen set up a gruel boiling function switch by above embodiment, the warmer switch that keeps original heat-preservation electric rice cooker, can be incubated for a long time after making the end of cooking, this is to be different from the advantage of the temperature control fully automatic electric cooker of application in person, because the utility model adopts timer, magnetic steel temperature limiter, temperature control to reduce the ingenious combination of caloric value circuit and warmer switch automatically, control electric meal, pot rice and gruel cooking, boil soup, processes such as insulation, it is multi-functional full-automatic that electric cooker is really accomplished, and cost is low, can be consumers in general and accepts.
