Water dispenser energy-saving control method and water dispenser control circuit

Abstract

The invention discloses a water dispenser energy-saving control method and a water dispenser control circuit. A first temperature sensor is used for detecting a temperature value of water in a water dispenser inner container and sending the temperature value to a central processing unit. The central processing unit calculates the temperature value to obtain a pulse control quantity required by an input end of a heating control execution module and drives an output end of the heating control execution module to obtain corresponding heating power. The control method comprises the steps of controlling hot water in the water dispenser inner container to be constant at a set temperature T0 and enabling heating power of a water dispenser to vary according to changes of T0. An extremely small temperature difference occurs between starting and shutdown of a heater, and almost no temperature difference occurs. Output power of the heater is controlled through a variable pulse fuzzy control heating algorithm based on a proportional integral differential (PID) controller, a fuzzy pulse control quantity is output, and energy is hardly consumed or an extremely small amount of energy is consumed within extremely short time. The water dispenser energy-saving control method and the water dispenser control circuit are suitable for all water dispensers.

Description

technical field [0001] The invention relates to the field of heating equipment control, in particular to a water dispenser energy-saving control method and a water dispenser control circuit. Background technique [0002] The water dispenser that office or family uses now all adopts the heating switch and the refrigeration switch of manual control water dispenser. In order to facilitate drinking at any time, the heating switch and cooling switch of the water dispenser are usually closed all the time, and the heater and refrigerator of the water dispenser are both in standby mode, resulting in a large power consumption of the water dispenser and wasting a lot of energy. Moreover, when no one drinks water after get off work, the water dispenser may be in the heating and cooling working state because the user forgets to turn it off, which wastes a lot of electric energy. [0003] The 24-hour standby energy consumption of hot and cold water dispensers stipulated by Energy Star i...
