Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with accompanying drawing (embodiment):

[0010] refer to figure 1 , figure 2 , the implementation of the present invention needs to include the following circuits: rectification filter circuit 1, anti-overflow detection circuit 2, water shortage detection circuit 3, button and indication circuit 4, control circuit 5, motor drive circuit 6, heat pipe drive circuit 7, buzzer drive circuit 8.

[0011] After the soymilk maker is energized and works, the water shortage detection circuit 3 detects whether the soymilk maker is short of water when the soymilk maker is working, and stops all work and reports to the police if it is short of water. The anti-overflow detection circuit 2 always detects whether there is an overflow signal in the soymilk machine. When an overflow voltage signal occurs, the anti-overflow probe received by the single-chip microcomputer (MCU) integrated chip in the control...

Abstract

The invention relates to a method for accurately distinguishing overflow signal of a soymilk grinder and a food processor in heating process; the method is characterized in that: after the soymilk grinder is powered on, an overflowing prevention detection circuit detects weather an overflow signal exists all the time, when an overflow voltage signal appears, a control circuit leads the overflow signal to carry out A / D conversion, and the digital signal is processed, and then according to the processing result, weather the overflow is false is judged, if yes, the heating is continued, if not, a signal for stopping heating is immediately sent out to a heating pipe driving circuit, so as to control the heating pipe to stop heating and prevent the soymilk from being overflowed. The method canaccurately prevent the soymilk grinder from foaming, so as to cause false overflow when in working, and lead the soymilk or liquid food to be cooked thoroughly or boiled out under the foaming condition.

Description

technical field [0001] The invention relates to a method, in particular to a method for accurately identifying overflow signals in the heating process of soybean milk machines and cooking machines. Background technique [0002] The anti-overflow detection circuit of traditional soybean milk machine and cooking machine uses the slurry resistance to connect with a fixed resistance R1 to form a series voltage divider circuit, and obtains whether there is an overflow signal according to the high and low level changes between the two resistance nodes. With the emergence of new whipping nets and non-net soymilk machines, it is inevitable that there will be foaming before the back-end cooking. The traditional anti-overflow detection circuit can no longer make a correct judgment on the overflow signal under various working conditions only by the level of the level. The purpose of cooking thoroughly. Thereby have a strong impact on the boiling effect or even be completely undercook...
