Description

Slag discharging cleaning control method and device of coffee machine and electronic equipment Technical Field The application relates to the technical field of coffee machine control, in particular to a slag discharging and cleaning control method and device for a coffee machine and electronic equipment. Background With the continuous improvement of the quality and the use experience of consumers, the full-automatic coffee machine is widely applied to home and business scenes. After the coffee extraction is completed, coffee grounds having a certain degree of compactness and adhesiveness are formed in the brewing chamber. The physical properties of the coffee grounds, such as hardness, structural integrity, adhesion to the cylinder wall, etc., are affected by a variety of factors including the roasting degree of the coffee beans, the grind size, the powder amount, the powder compaction pressure, etc., and thus the state of the grounds formed after each brew may vary significantly. Currently, the slag discharging system of most of the full-automatic coffee machines depends on a preset fixed program. Specifically, the system pushes the coffee grounds out of the brewing cylinder with a fixed stroke through the piston rod. The design of the fixed procedure for discharging the coffee grounds out of the brewing cylinder simplifies the control logic, but can not sense or respond to the state of the coffee grounds, and has a plurality of problems in the practical application process: On the one hand, upon encountering a hard, highly adherent cake, the fixed push rod force may not be sufficient to cause it to completely peel off and expel. The residue cake is broken and remains in the brewing cavity, so that the flavor of the subsequent coffee is polluted, bacteria are more bred after long-term accumulation, a residue discharge pipeline is blocked, and even machine faults such as piston clamping stagnation or sealing failure are caused. On the other hand, for loose and easily discharged slag cakes, a set of fixed powerful slag discharging procedures designed for coping with severe conditions can cause excessive consumption of energy and unnecessary abrasion of mechanical parts, and generate unnecessary noise. In addition, manual intervention of a user can be frequently triggered due to incomplete slag discharge, so that the automation and intelligence level and the use experience of the user of the coffee machine are obviously reduced.
