【Abstract】 The structure and work process of the entire boiling water electric heating were elabrated.And givened the functional block diagram,designed the temperature detect and the control circuits,the fluid position detect and control circuits,the leakage detect and control circuit.The security of this system has been guaranteed by leakage protecting and pressure-limiting valve protecting.the unboiled water and the boiling water were separated completely,that guaranteed the entire boiling water to people.The system was controled by the MCU,has many functions of the automatic temperature detecting,warm controling, water given controling, water scarcity protecting,leakage protection and energy saving.更多还原
