HK1160553A1 - Power supply, electric apparatus with water purification function, and signal processing method for water treatment - Google Patents

Abstract

The invention provides a power supply for supplying a descaling function for an electric appliance, comprising an input module, a voltage reduction module, a rectifier module, a first voltage stabilizing module, a second voltage stabilizing module, a modulation module, a mixing module and an output module, wherein the input module is connected with a power grid and used for providing an input electric signal; the voltage reduction module is connected with the input module and used for forming a low-voltage electric signal; the rectifier module is connected with the voltage reduction module and used for forming a low-voltage direct-current electric signal; the first voltage stabilizing module and the second voltage stabilizing module are connected with the rectifier module in parallel and are used for forming a first voltage stabilizing direct-current electric signal and a second voltage stabilizing direct-current electric signal; the modulation module is connected with the first voltage stabilizing module and used for modulating to generate a direct-current pulse signal; the mixing module is connected with the modulation module and the second voltage stabilizing module and used for mixing to generate an alternating-current pulse signal; and the output module is connected with the input module and the mixing module and used for forming an overlapped output electric signal and applying the overlapped output electric signal to the electric appliance to be descaled. The invention also provides the electric appliance with a water purifying function and a signal process method for water treatment.
