A discharge valve operating device includes a first linking member and a second linking member, a rotary winding device, and an operation unit configured to rotationally operate the rotary winding device, wherein when the operation unit rotationally operates in a first direction, the operation unit is configured to perform toilet flushing in a full-flushing mode by pulling up the discharge valve by a first length by the rotary winding device winding the first linking member by the first length in the first direction, and when the operation unit rotationally operates in a second direction opposite to the first direction, the operation unit is configured to perform toilet flushing in a partial-flushing mode by pulling up the discharge valve by a second length by the rotary winding device winding the second linking member in the second direction by the second length which is the same as the first length.

Discharge valve operating device, flush water tank device, and toilet system

A flush water tank apparatus capable of stable operational control of a discharge valve apparatus, and stable flush water supply to a toilet for long term. The flush water tank apparatus of the present invention includes a power drive unit comprising a motor and an output shaft, being a power drive unit capable of electrically operating a drain valve on a drain valve mechanism; and a housing portion formed so as to surround the perimeter of the outlet on a drive unit internal air passage extending from the motor in the interior of the flush water tank; wherein an air passage communicating from the motor of the power drive unit through the housing portion to the exterior of the flush water tank is formed.

Flush water tank apparatus

A wall-mounted type toilet fixing device includes a flush water tank device that is hidden in an area behind a wall, and a fixing unit, the fixing unit includes support portions, a toilet fixing portion, a pair of left and right legs, and a drain pipe connection, and the pair of legs are disposed outside from the drain pipe connection and inside from a side wall of a toilet body in elevation view, and are disposed laterally asymmetrically to each other with respect to a central axis passing through a center of the drain pipe connection and dividing the fixing unit equally in a left-right direction, in a state where the toilet body is fixed to the toilet fixing portion.
