Your so-called water level sensor actually contains two meanings - the first is not too little water. The second water can't be too much
Water must reach the lowest water level, at this time the temperature sensor (lower end) works, the water is not over the temperature sensor machine does not work (water temperature is too high, the system default soy milk has been good, will not work, so it is best to warm the water)
Boiling water level can not exceed the highest, at this time there is an anti-spill electrode, when the soybean milk to the top, the anti-spill electrode sense, will automatically reduce half the power, soy milk will go down, so repeated boiling of soy milk nutrition can be released to prevent false boiling phenomenon
And your so-called temperature sensor, only Jiuyang in the industry has this technology ~ in this way, I hope to help you
