Abstract

The utility model relates to a double timing multifunction electric rice cooker composed of two single timers. The utility model is characterized in that a timer 01 is connected in series with the other timer 02 through the reed contact C0 of the timer 01, the reed contacts A, B of the timer 02 are separately connected in series with the parallel circuit of a magnetic steel temperature limiter K1 and a heat retainer K2 and the temperature control automatic heat value reduction circuit, and then the reed contacts A, B are connected in series with a heating element RR simultaneously. One end of the motor M2 of the timer 02 is connected to the heating element RR and a power supply, and the other end is connected to the reed contact B. One end of the motor M1 of the timer 01 is connected to the heating element RR and the power supply, and the other end is connected to a reed contact E. The utility model has the advantages of convenient timing setting, easy manufacture, no energization of the motors of the timers, little power consumption, and long service life.

Description

The plesichronous multifunctional electric rice cooker that two single timers are formed

The utility model relates to a kind of plesichronous multifunctional electric rice cooker that adopts two single timers to form.

Plesichronous multifunctional electric rice cooker by my application, (number of patent application is 95243794.5) is the patented product dual timer timing of adopting me, make multipotencys such as electric cooker has anti-overflow, the Baoshang of cooking, cook congee, shortcoming is that timer is made complexity, set and easily get wrong, and motor is switched on always when cooking, and power consumption influences electrical machinery life again.

For overcoming above-mentioned shortcoming, a kind of plesichronous multifunctional electric rice cooker of being made up of two single timers is provided, and makes when cooking, the timer motor is not worked.

The technical solution of the utility model is: it includes pot body, heater element RR, magnetic steel temperature limiter K1, warmer K2, timer and temperature control reduce the caloric value circuit automatically, be characterized in that the timing that timer adopts two timers to control electric cooker respectively leaves and regularly close, timer D1 is in series by its reed contact CD and another timer D2, the reed contact A of D2 and B connect with heater element RR respectively with after the parallel circuit of magnetic steel temperature limiter K1 and warmer K2 and temperature control reduce the caloric value circuit automatically and connect jointly again, motor M 1 one ends of timer D2 are connected with heater element RR and power supply, the other end is connected with reed contact B, timer motor M 1 one ends connect heater element RR and power supply, and the other end is connected with reed contact E.

The utility model embodiment is further described in conjunction with the accompanying drawings.

Fig. 1 is the circuit diagram of embodiment 1,

Fig. 2 is the circuit diagram of embodiment 2.

By shown in Figure 1, the electric cooker circuit is by heater element RR, magnetic steel temperature limiter K1, warmer K2, timer and temperature control reduce the caloric value circuit automatically and form, temperature control reduction caloric value circuit is formed in parallel with the temperature-sensitive element K3 that can disconnect to 80 ℃ after being connected by heating element heater R and diode d again, timer D1 is in series by its reed contact CC and another timer D2, the reed contact A of D2 and B connect with heater element RR after the parallel circuit of magnetic steel temperature limiter K1 and warmer K2 and temperature control reduce the caloric value circuit automatically and connect respectively more jointly, motor M 2 one ends of timer D2 are connected with heater element RR and 220 volts of AC powers, the other end is connected with reed contact B, motor M 1 one ends of timer D1 connect heater element RR and power supply, and the other end is connected with reed contact E.

When cooking, according to the circuit of present embodiment, if need cook immediately, then do not need to stir the timer dial,, just can cook as long as press magnetic steel temperature limiter K switch 1, if will regularly cook, then need stir regularly and open, timer D1 dial just can be started working to the time that need begin to cook, and this moment is by the RR heating with full power, K1 disconnects in the time of 103 ℃, changing has 2 insulations of insulation K switch, in the process of cooking, and the motor M 1 of two timers and the equal no power of M2.

Cook congee, during the multi-functional cooking such as Baoshang, K1 does not press, and carries out the timing starting by timer D1 and E2 respectively and sets with regularly closing, and one after the timing starting, CDEF connects, this moment, by the high-power heating of heater element RR, timer D2 motor K2 worked by temperature-sensitive element K3, heating-up temperature is higher than 80 ℃, K3 disconnects, and this moment is through diode and the heating of heater element R, RR series connection small-power, until regularly closing.This moment, AF connected, by insulation K switch 2 temperature.If will make regularly the pass time more definite, between motor M 2 and reed contact B, be connected to a temperature-sensitive element K4 to 85 ℃ of conductings, after regularly opening end, when heating-up temperature is lower than 85 ℃, K4 is conducting not, motor K2 does not turn round, when being heated to 85 ℃, K4 conducting, motor K2 work, until regularly closing, this moment, AF connected, and by 2 insulations of insulation K switch, so regularly when the shut-in time from beginning to depend on that food species, quantity reach supply voltage at that time before heat time heating time to 85 ℃, so just make the regularly shut-in time, more definite.

By shown in Figure 2, on the inside recess wheel of it and embodiment 1 different is timer D2 first pit and second pit are set, what another point was different is to cook, cook congee all magnetic steel temperature limiter K switch 1 to be closed, can not cause maloperation, when cooking, stir the dial of timer D2, make the reed boss enter second pit 2, this moment, reed contact AF connected, and the process of cooking is identical as embodiment 1 process of cooking.

When cooking congee, whether close irrelevantly, make the reed boss extract first pit of inside recess wheel as long as stir timer D2 dial with K1, at this moment, D2 reed contact BF connects, and promptly sets the regularly shut-in time, because the CD of D1 connects, thereby after timing such as begin to cook congee closes, power supply disconnects and not being incubated, and its process of cooking congee is also the same with embodiment 1, and the advantage of present embodiment is no matter to cook congee to cook all can press K1, can not cause maloperation, and regularly close thoroughly outage of back.

The utility model advantage is both to have kept to apply in person full-automatic heat-preservation electric rice cooker (application number 95243315.k) and afterwards improved Double-timing multi-function electric cooker (number of patent application is 95243794.5) advantage, again so that timer motor no power in the process of cooking, power consumption subtracts Few, and the life-span is long.
