Abstract
There are provided a valve control system, a bidet using the same, and a valve control method. The valve control system includes a latch valve controlling a stream of water in a pipe; a flow rate sensor measuring a flow rate in the pipe; and a valve control device controlling the operation of the latch valve. The valve control device determines whether or not the latch valve is malfunctioning upon analyzing a flow rate measured by the flow rate sensor. When the latch valve is malfunctioning, the valve control device controls the latch valve to re-operate.
Claims16
A valve control system comprising:
- a latch valve controlling a stream of water in a pipe;
- a flow rate sensor measuring a flow rate in the pipe;
- and
- a valve control device determining that the latch valve is malfunctioning if a flow rate value measured by the flow rate sensor is not within a pre-set flow rate value range corresponding to a valve operation and controlling the latch valve to re-operate in the occurrence of the malfunction.
A bidet comprising:
- a control device controlling an operation of the bidet upon receiving information regarding a user's bidet manipulation;
- and
- one or more of a waterway pipe supplying water required for operating the bidet,
- wherein one or more of the waterway pipe includes:
- one or more of latch valve controlling a stream of water in the waterway pipe, respectively;
- and
- one or more of flow rate sensor measuring a flow rate in the waterway pipe,
- wherein when the control device determines that the latch valve is malfunctioning if a flow rate value measured by the flow rate sensor is not within a pre-set flow rate value range corresponding to a valve operation, and performs a function of controlling the latch valve to reoperate in the occurrence of the malfunction.
A valve control method using a valve control system including a latch valve and a flow rate sensor installed in a waterway pipe, the method comprising:
- a valve operation process of opening or shutting the latch valve;
- and
- a malfunction determination process of determining that the latch valve is malfunctioning if a flow rate value measured by the flow rate sensor is not within a pre-set flow rate value range corresponding to a valve operation,
- wherein when the latch valve has malfunctioned, the valve operation process is performed again.
