Abstract
The invention relates to a method for controlling automatic heat preservation of an intelligent soymilk machine. When the soymilk machine finishes cooking soybean milk, the temperature of the soybean milk falls; and when the temperature reaches a set lower limit, a temperature sensor detects the situation and transmits an abnormality signal to an MCU so that the MCU drives a heating device to reheat the soybean milk, wherein the temperature sensor continues detecting the temperature of the soybean milk in the process, and transmits a signal to the MC when the temperature reaches certain upper limit value so that the MCU heating device stops heating to finish the function of heat preservation. The process can be performed circularly so that users can drink hot soybean milk at any time. In an automatic heat preservation device for the intelligent soymilk machine, a +5V power supply supplies electricity to a control IC and the temperature sensor, and a heating resistor is supplied with electricity by 220 V alternating current; and the temperature sensor transmits the detected temperature to the MCU; when the detected temperature is lower than 40 DEG C, the MCU starts the heating resistor to heat the soybean milk; and when the detected temperature is higher than 70 DEG C, the heating resistor stops heating and the temperature is detected over again.
