Timing and variable water boiler based on STM32

Abstract

The invention discloses a timing variable water boiler based on STM32. The water boiler uses multiple water tanks to re-use the lost or about to be lost heat, and supplies water at regular intervals according to actual needs to precisely control the amount of boiled water. The boiling water tank is filled and boiled according to the water consumption; the water storage tank is used to store the boiled water in the boiling water tank and keep it warm; the cold water tank is used to store the boiled water and provide cold boiled water to the user. If it is not used up, the water in the water storage tank is injected into the cold water tank through the one-way solenoid valve. The boiling water tank and the water storage tank have built-in heating tubes, and a corresponding number of heating tubes are used to heat and keep warm according to different water volumes. The heat exchanger installed on the upper part of the boiled water tank is fixed in the tap water tank, and the heat is transferred to the tap water through the heat exchanger; the cold water tank and the tap water tank use float valves to control the opening and closing of the valves to increase and discharge water. The exterior of each water tank is covered with polyurethane material to insulate heat exchange with the external environment and reduce power consumption.

Description

technical field [0001] The invention relates to the field of mechanical design and automatic control, in particular to a timing variable water boiler based on STM32. Background technique [0002] Many units in industrial and mining enterprises, schools, libraries, and student dormitories are equipped with water boilers; water boilers sold on the market include boiling water boilers, stepping water boilers, etc. There are the following deficiencies: (1) the daily water supply is greater than the demand, and it is always running at full water level, resulting in serious power loss and large power consumption; Not good, causing the water boiler to repeatedly heat the excess water, and at the same time there is a situation of mixing hot and cold water, which is not conducive to health; (3) The water boiler has poor heat preservation effect and serious heat loss. And this part of heat is not recycled effectively. [0003] At present, there is a new type of instant water boiler ...
