  • Patent number: 10151091
    Abstract: A toilet apparatus according to an embodiment includes a wall-mounted-type toilet body, a sanitary washing device, a switching part, and a fixation member. The toilet body includes a skirt part that forms an outline of a toilet bowl. The sanitary washing device is disposed on a top face of the toilet body and washes a private part of a user. The switching part can execute at least one of a first operation and a second operation, wherein the first operation is to switch a supply and a stop of water to the sanitary washing device, and the second operation is to switch a supply and a stop of electric power to the sanitary washing device, and wherein the first operation and the second operation are executed manually. The fixation member fixes the switching part at a manually operable position inside the skirt part, wherein the switching part is manually operable at the position.

  • Patent number: 9719238
    Abstract: The present invention relates to an operating device for a flush water tank device in a flush toilet wherein manual and motorized control units are configured to actuate a flush valve by means of a single connecting member operably connecting the manual and motorized control units to the flush valve. The operating device is characterized by a single connecting member operatively connected to the flush valve for opening and closing the flush valve depending on a pull-up amount of the connecting member, a manually operating unit for pulling up the single connecting member when a user performs a manual operation for the control unit, and an electrical drive unit adapted to pull up the single connecting member so as to actuate the flush valve by using an electrical power from an external power source.

  • Patent number: 9689155
    Abstract: 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.
