PURPOSE: An automatic water pressure control device for a bidet and a method thereof are provided to regularly discharge washing water through a nozzle by steadily and automatically controlling water pressure of the washing water within a predetermined water pressure. CONSTITUTION: An automatic water pressure control device comprises a water pressure control unit. The water pressure control unit(300) comprises a flowmeter(310), a control unit(320), and a water quantity control valve(330). The flowmeter comprises an impeller(311), a magnet(313), and a hall sensor(314). The hall sensor senses a pulse generated due to the rotation of the magnet. The control unit calculates water pressure by calculating the number of an output waveform transmitted from the hall sensor. The water quantity control valve controls supply quantity of washing water according to the calculated water pressure. |
