Heat-generating disc in electric cooker to reach 103 DEG C, only cooks rice and can arrive this temperature, burns gruel, boils face, heats up water, stewed chicken soup, steamed sweet bun etc. all do not reach so high temperature. So popular electric cooker is after being powered up, as long as you do not close the power supply of electric cooker, electric cooker is just in all the time and uninterruptedly adds thermally state, until the water in electric cooker is dryouied, if run into suddenly busy go out or watch TV and forget close electric cooker power supply, electric cooker is electrically energized long-time heating, gently then burns out the heat-generating disc of electric cooker, heavy then the likely hidden danger such as initiation fire, but also waste unnecessary electric power.
For the drawbacks described above that popular electric cooker exists, if using time base circuit to make the time delay circuit design more than 30 minutes with manufacturing technology is the bottleneck being difficult to break through, for effectively solving the technical barrier of time base circuit long delay, popular electric cooker long delay supply socket of the present invention is on the basis of typical case's time base circuit delay circuit, only in delay circuit, increase several common components, namely achieve the technology requirement of used time base circuit production Long-time-delay circuit. So both solved popular electric cooker can not timing problems, laser heating after simultaneously solving again popular electric cooker energising and waste the problem of the energy, reached the purpose of electric cooker safety utilization of electric power, using electricity wisely.
Popular electric cooker long delay supply socket of the present invention involved necessity, guardian technique content in implementation process described further below.
