After number, then the rule reducing.Can judge whether this strength signal is less than peak signal after receiving each strength signal, if
It is more than, then replace peak signal with this strength signal；If being less than, determine whether the difference between strength signal and peak signal
Whether value is more than predetermined threshold value, if it is not, then showing that water is just boiled, also needs to seethe with excitement completely；If it is determined that water is completely boiled.
It is further that strength signal when water is finally boiled is more or less the same with peak signal it is contemplated that when the water yield is less,
Therefore, when the difference between strength signal and peak signal is less than predetermined threshold value, also include：
Judge whether all strength signals receiving in preset duration are respectively less than peak signal；
If it is determined that water is boiled.
Specifically, when the water yield is less, strength signal when completely boiled is compared peak signal and is reduced less, may miss
It is not judged to water boiled and heat up water always, and then leads to water to dryout, for avoiding water to dryout, can determine whether the institute receiving in preset duration
Have whether strength signal is respectively less than peak signal, when being less than always, then it is believed that the current water yield is less and water is boiled.
Finally it should be noted that：Various embodiments above is only in order to illustrating the technical solution of the utility model, rather than it is limited
System；Although being described in detail to this utility model with reference to foregoing embodiments, those of ordinary skill in the art should
Understand：It still can be modified to the technical scheme described in foregoing embodiments, or to wherein some or all of
Technical characteristic carries out equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from this practicality new
The scope of type each embodiment technical scheme.
