A smart power saver based on composite switch and self-learning fuzzy control for drinking water dispenser

A smart power saver based on composite switch and self-learning fuzzy control for drinking water dispenser is developed in order to solve some problems existing in drinking water dispenser widely used in offices and homes, such as wasting power energy and producing 'thousands of boiling water'. A single-chip microcomputer is used as CPU and self-learning fuzzy control is adopted as control strategy to reduce ineffective heating of drinking water dispenser. In order to improve power saving effect, some low consumption designs of power saver is proposed. Composite switches and buzzer warning circuit designed are also proposed to reduce conduction loss. In addition, the power saver has multiple operation modes so that it can be applied to different requirements of the occasion. The experimental data shows that power saving effect of the power saver is significant, and it is worth to be further popularized.
