BIDET CONTROL METHOD USING A SMALL AMOUNT OF WASHING WATER AND A WATER HAMMER PREVENTION METHOD OF A BIDET

摘要

PURPOSE: A bidet control method and a water hammer prevention method of a bidet are provided to automatically wash a toilet bowl using washing water stored in a pressure chamber of a main body of a flush valve.;CONSTITUTION: A bidet control method is as follows. When a washing order or bidet order is generated from an order generation unit, a solenoid valve is opened to send washing water from a pressure chamber of a washing water supply valve to a control unit. Washing water is supplied to a washing nozzle or bidet nozzle by rotating a three-way changeover valve. After a pre-set washing time or bidet time, the three-way changeover valve is restored to the original state thereof, and the solenoid valve is closed.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB,DD,GG,HH) No; (CC,EE,FF,II,JJ) Yes; (KK) Operation time of a bidet passes away?; (S300) A user is detected?; (S302) Operating a timer; (S304) A washing order?; (S306) A bidet order?; (S308) Opening a solenoid valve; (S310) Switching a three-way changeover valve to a washing nozzle to prevent the pressure of a pressure chamber from lowering; (S312) Washing time passes away?; (S314) Restoring the three-way changeover valve to the original state thereof; (S316) Closing the solenoid valve; (S318) Opening the solenoid valve; (S320) Switching the three-way changeover valve to a bidet nozzle to prevent the pressure of a pressure chamber from lowering; (S324) Restoring the three-way changeover valve to the original state thereof; (S326) Closing the solenoid valve
