Overflow preventing control method of wall-breaking food processer and wall-breaking food processer

Abstract

The invention relates to an overflow preventing control method of a wall-breaking food processer and the wall-breaking food processer and belongs to the field of food processing. The food processer comprises a master control chip, a stirring cup, an overflow preventing device, a heating device and a water level sensor and is characterized in that the overflow preventing control method comprises, at least, the steps that an overflow value is self-adjusted, wherein the master control chip reads the overflow value detected by the overflow preventing device as an overflow reference value A; correction is performed, the water level sensor detects the electric conductivity of slurry in the stirring cup, and the master control chip calculates and stores an overflow trigger value C according to the electric conductivity of the slurry; overflow is judged, wherein the master control chip reads a current overflow value B in the heating process in real time, compares the current overflow value B with the overflow reference value A and obtains a calculation value, the calculation value is compared with the overflow trigger value C so as to judge whether overflow processing is performed or not. By adopting the control method, the overflow trigger value can be corrected in real time, and the probability of overflow preventing failure and erroneous judgement is reduced.

Description

technical field [0001] The invention relates to the field of food processing, in particular to an overflow prevention control method for a broken wall cooking machine and a broken wall cooking machine. Background technique [0002] Existing heating and cooking machines with anti-overflow function usually only use anti-overflow device as the sensor for judging whether the heating is overfilled. The main control chip has a fixed overflow trigger threshold, and when the trigger condition is met during the heating process, the anti-overflow action will be performed. Moreover, the overflow trigger threshold of the existing cooking machine is a fixed value set according to the empirical value obtained from the experimental test data. However, in practical applications, the overflow trigger thresholds of slurries made of different materials are different, and the conductivity of the slurry changes continuously during the crushing and heating process of materials, and different over...

AI Technical Summary

Problems solved by technology

Especially when the anti-overflow device is stuck and the slurry or crushed material cannot fall off, the anti-overflow signal will maintain a low value for a long time, which may cause the anti-overflow to fail or trigger the anti-overflow for a long time. affect the heating effect

However, none of the existing heating cooking machines can adjust the overflow trigger threshold according to the different types of materials in the slurry and the real-time changes of the materials during the crushing and heating process, so the overflow prevention is not accurate and reliable enough.
