A toilet device includes a toilet body that has a toilet bowl, a toilet seat that is attached to the toilet body and has a bowl facing surface facing an inner surface of the toilet bowl in the up-and-down direction and provided on a back surface thereof, a discharge part that can discharge a cleaning liquid so that the cleaning liquid runs along a bowl facing surface, and a guide that can guide a part of the cleaning liquid so that the cleaning liquid runs along an inner peripheral side portion of the bowl facing surface.

Toilet device and toilet seat unit

A first cleaning nozzle and a second cleaning nozzle configured to be capable of being advanced and retracted and perform private part cleaning on a human body in an advanced state; a shutter configured to open and close an opening through which the first cleaning nozzle and the second cleaning nozzle are advanced and retracted; and a shutter water film forming portion configured to supply water to a front surface of a shutter main body of the shutter to form a water film are provided.

Private part cleaning device and toilet

A toilet flush tank is provided that is capable of preventing an increase in the external dimensions of a toilet main body even when the toilet flush tank is placed below the upper surface of a toilet main body and is also capable of performing toilet cleaning in a stable manner. A toilet flush tank stores cleaning water to be provided to a toilet main body having a toilet bowl and a toilet drainage channel that communicates with the downstream side of the toilet bowl. This toilet flush tank is placed inside a space below the toilet bowl and provided with a recessed portion that conforms to the shape of the toilet drainage channel at the upper surface of the toilet flush tank.

Toilet flush tank

Air suction device for a flush toilet configured to suction air from a toilet drain duct having a suction chamber dividing a tank body interior, a float in the suction chamber and an on-off valve closing an air inlet when the float lifts to prevent air flow from the toilet drain duct side into the suction chamber. The air inlet is higher than the water level in a toilet flushing standby mode. The on-off valve opens the air inlet to allow air flow form the drain duct side in the suction chamber when flush water in the tank drops such that the float is lowered form the raised position. An embodiment includes a valve chest, a float and attracting member for on-off valve manipulation. Another embodiment includes a valve chest with a small air flow manipulation hole.
