Abstract:
A flush toilet comprising a toilet body, a water supply pipe connected to supply wash water, a discharge port connected to discharge wash water, a valve disposed between the water supply pipe and the discharge port, a valve switching device operably connected to switch the valve, a spring connected to drive the valve switching device, a mechanical timer, comprising a generator driven by the spring and a variable resistor connected to the generator, and a starter operably connected to supply the spring with strain energy, whereinthe spring releases the strain energy accumulated in it to drive the valve switching device, the mechanical timer consumes a part of the strain energy released from spring to regulate a duration of the operation of the spring, the variable resistor is connected to adjust the rate of the strain energy consumption by the mechanical timer to adjust the duration of the operation of the spring, and the variable resistor is selectable among a plurality of different rates of strain energy consumption.
