A valve control system may include 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, wherein the valve control device may include a first timing device determining the number of re-operations of the latch valve, and wherein when the number of re-operations of the latch valve determined by the first timing device exceeds a pre-set number, the valve control device may control the latch valve to perform a reverse operation of the operation performed during the re-operations.

Valve control system, bidet using the same, and valve control method

A generator includes: an upper housing and a lower housing; a water inlet and a water outlet provided in the upper housing; an impeller rotatably fixed inside the upper housing; a magnet provided in the lower housing, connected to a rotating shaft of the impeller, and rotated integrally with the impeller; and a bobbin positioned outside the magnet. A bearing through which the rotating shaft passes and a communication hole connecting a space for housing the impeller to a space for housing the magnet are disposed in an intermediate surface between the space for housing the impeller and the space for housing the magnet.

Generator and bidet comprising the same

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.

There is provided a self-generating bidet that can perform power-generation using water supplied to the bidet or a water tank. The self-generating bidet, injecting water through a nozzle part, includes a water inlet into which water is introduced; a generator generating power through the water introduced by the water inlet; a charging unit storing electricity generated from the generator; and a nozzle passage part provided between the generator and the nozzle part to supply the water passing through the generator to the nozzle part. The self-generating bidet further includes a controller controlling the generator to be driven by opening a passage of the nozzle passage part in order to allow the water to be discharged through the nozzle part when a voltage of the charging unit is lower than a predetermined reference voltage.
