Abstract:
1. A switching device for rim water in a low tank toilet, comprising: a water supply tube that guides water from a filler valve to a rim of a toilet bowl in response to operation of a flush handle; a supply water switching unit that is installed in an operating chamber formed through the water supply tube and that opens or closes a flow channel of the water supply tube in response to operation of a switching control unit, with a fill-up water inlet hole being formed through the supply water switching unit so that, when the flow channel is closed, some water supplied from the filler valve can be supplied to the rim; the switching control unit that pulls the supply water switching unit according to a reduction in a water level inside a vertical pipe thereof and closes the flow channel so that a toilet tank can be filled with water that is supplied from the filler valve; and a water supply control unit that is operated in such a way that, when the switching control unit pulls the supply water switching unit, in a normal state, a guide port on/off unit that is mounted to a discharge guide port moves downward and a float that is combined with the guide port on/off unit moves downward according to a reduction in a water level of the toilet tank so that the discharge guide port that is formed through a lower end of the vertical pipe can be opened and water is discharged from the vertical pipe through the open discharge guide port and, accordingly, the switching control unit can quickly move downward, however, when the toilet bowl is blocked and, accordingly, the water level is not reduced, the water supply control unit maintains a closed state of the discharge guide port.
