Instantaneous electric water boiler

The invention discloses an instantaneous electric water boiler. The instantaneous electric water boiler consists of a water pump, a sterilization/filtration system, a three-way valve, a drain valve, awater inlet pipe, a transition cavity, a floater, a photoelectric switch, a water return pipe, an electric heater, a heating cavity, a normal temperature water inlet pipe, a normal temperature wateroutlet, a water outlet and a water storage box, and also comprises a set of control system, wherein the control system consists of a main control loop, an operating system and a display system. Underthe action of the main control loop, water in the water storage box is delivered into the sterilization/filtration system through the water pump at a certain time interval for sterilization and filtration, and then flows back into the water storage box through the transition cavity and the water return pipe for use. 本发明公开了一种即热式烧水机，包括是由水泵，杀菌/过滤系统，三通阀，排水阀，进水管、过度腔，浮子、光电开关、回水管,电加热、加热腔、常温水进水管、常温水进水口、出水口和储水箱构成；还包括一套控制系统，由主控制回路，操作
