FLUSH WATER VOLUME REGULATOR, FLUSH WATER TANK APPARATUS COMPRISING SAID FLUSH WATER VOLUME REGULATOR, AND FLUSH TOILET COMPRISING SAID FLUSH WATER TANK

摘要

A flush water volume regulator is provided, capable of constraining the occurrence of a buoyancy force acting on a water reservoir, whereby flush water in the water reservoir can be circulated with flush water in a flush water tank outside the water reservoir. The flush water volume regulator 38 of the invention has a water reservoir, being a water reservoir 40 disposed inside this flush water tank 16, capable of storing a predetermined amount of flush water, on which an opening 40a through which flush water within water reservoir 40 and flush water outside water reservoir 40 can pass, and an opening-closing valve 42 for opening 40a during the standby state before starting a flush and for blocking opening 40a or reducing the opening surface area of opening 40a when the water level inside flush water tank 16 is dropping after starting a flush.

主权项

1. A flush water volume regulator capable of regulating the volume of flush water discharged to a toilet, disposed on a flush water tank apparatus having a water supply apparatus supplying water into a flush water tank from a water source for flushing a toilet, and a discharge valve apparatus for opening and closing a discharge flow path, disposed on the bottom surface of a flush water tank and communicating with a toilet; having:
a water reservoir, being a water reservoir disposed inside the flush water tank and capable of storing a predetermined quantity of flush water, in which an opening is formed through which flush water in the water reservoir and flush water outside the water reservoir can flow; and an opening-closing valve for releasing the opening in a standby state prior to starting a flush, and for blocking off the opening or reducing the opening surface area when the water level inside the flush water tank is dropping after a flush is started.
