ABSTRACT:
A steam cleaner with multiple protections includes a machine body, in which first and second protections are provided. The first protection includes a pressure controller and a relief valve, and the second protection includes a temperature controller and a fuse unit. When a boiler provided in the machine body has an internal pressure or an internal temperature exceeded a value preset for the pressure controller or the temperature controller, respectively, a power control unit automatically power off the steam cleaner. When the boiler has an internal pressure exceeded a value preset for the relief valve, steam is immediately discharged from the boiler, and when the boiler has an internal temperature exceeded a value preset for the fuse unit, heating of the boiler is immediately stopped to avoid any danger.
