Automatic flushing apparatus of bidet and method of controlling the same

Abstract

Provided are an automatic flushing apparatus of a bidet and a method of controlling the same. The automatic flushing apparatus includes: a flushing switch; a flushing drive motor driven under control of a controller; a flushing switch; a flushing drive motor driven under control of a controller; a rotating body connected to a shaft of the drive motor and having a magnet buried in its outer periphery; a hole sensor formed adjacent to an outer periphery of the rotating body to detect the magnet; a timer for counting seconds in real time; and a controller for driving the drive motor to set to an initial position such that the magnet is detected by the hole sensor when the flushing switch is input, and varying an operation time of the drive motor depending on urine or feces to perform the flushing operation. Therefore, it is possible to reduce water consumption, prevent leakage of water due to malfunction of a drive motor, and improve reliability of an automatic flushing operation by differently performing the flushing operation depending on urine or feces.

1 . An automatic flushing apparatus of a bidet, comprising:
 a flushing switch;   a flushing drive motor driven under control of a controller;   a rotating body connected to a shaft of the drive motor and having a magnet buried in its outer periphery;   a hole sensor formed adjacent to an outer periphery of the rotating body to detect the magnet;   a timer for counting seconds in real time; and   a controller for driving the drive motor to set to an initial position such that the magnet is detected by the hole sensor when the flushing switch is input, and varying an operation time of the drive motor depending on urine or feces to perform the flushing operation.   
   
   
       2 . A method of controlling an automatic flushing apparatus, comprising:
 a first step of inputting a flushing switch:   a second step of rotating a drive motor under control of a controller when the flushing switch is input, and stopping the drive motor to set to an initial position when a magnet attached to an outer periphery of the rotating body is detected by a hole sensor;   a third step of determining an input state of the flushing switch after the initial position setting;   a fourth step of driving, at the controller, the drive motor for T seconds and then stopping the drive motor when it is determined that the result is urine; and   a fifth step of driving, at the controller, the drive motor for F seconds and then stopping the drive motor when it is determined that the result is feces.   
   
   
       3 . The method according to  claim 2 , wherein the T seconds are smaller than the F seconds. 
   
   
       4 . The method according to  claim 2 , further comprising the step of additionally driving the drive motor until the magnet is detected by the hole sensor, after driving the drive motor for the T or F seconds, such that the initial setting operation is omitted during a new flushing operation.
