    • A hot water pressure washer with an automatic burner cool-down includes a water inlet assembly, a low pressure water supply assembly, a coil outlet assembly, a control system, and other related components which are required for the functionality of the pressure washer. A shut-down timer of the control system shut down a power source so that the pressure washer can be automatically shut down through the control system when the pressure washer is not operated. Then a cool-down timer of the control system efficiently cools down a heating coil of a burner assembly. The cool-down timer activates the water inlet assembly, the low pressure water supply assembly and the coil outlet assembly through a pair of solenoid valves in order to cool down the heating coil, where the thermal energy within the heating coil is removed from a phase change of water into water vapor and convection.
    • 具有自动燃烧器冷却的热水压力清洗机包括压力清洗机功能所需的进水组件,低压供水组件,线圈出口组件,控制系统和其它相关部件。 控制系统的停机定时器关闭电源,以便当压力清洗机不工作时,压力清洗机可以通过控制系统自动关闭。 然后,控制系统的冷却定时器有效地冷却燃烧器组件的加热线圈。 冷却定时器通过一对电磁阀激活进水组件,低压供水组件和线圈出口组件,以便冷却加热线圈,其中加热线圈内的热能从相位移除 将水变成水蒸汽和对流。
