The present invention relates to a cover for a toilet bowl comprising: a rotary flange formed at a rear portion; a cover member rotatably coupled to the rotary flange; a toilet seat to which the cover member is coupled; a rotary support panel coupled to the toilet bowl and having a spherical rotary guide groove formed therein; a rotary member coupled to the rotary support panel so as to rotate and connecting the cover member and the toilet seat to the toilet bowl; a rotary assembly provided at the rear of the toilet seat and connected to an end of the rotary member to rotate the rotary member when the positions of the toilet seat and the cover member have been changed; and a water flushing device for operating a water flushing means by using a rotational force.

Various embodiments for conserving fluid based on the position of a toilet seat are presented. One example embodiment includes a toilet flushing system having a fluid regulation component and a position detector. The fluid regulation component is configured to regulate an amount of fluid used to flush a toilet during a flush cycle. The position detector is configured to detect whether the toilet seat is in a raised position or a lowered position. The position detector is coupled to the fluid regulation component to communicate whether the toilet seat is in the raised position or the lowered position. The fluid regulation component is further configured to regulate the amount of fluid used during the flush cycle based at least in part on whether the toilet seat is in the raised position or the lowered position.

Provided is an unpowered and automatically flushing toilet seat, for a water tank, having detachable and waterproof functions. A loading lever rotates, for the descending movement of a toilet seat, and presses a loading member, thereby enabling enhancement of the transmission efficiency of the force and smooth operation. Since the loading member maintains the loaded state until a toilet paper time and flush control unit presses and releases the loading member, which has been moved and loaded by the pressing of the loading lever, a user can easily acquire time for discarding toilet paper.

According to one embodiment, a sanitary washing device includes a main part, a toilet seat, and a radio wave sensor. The main part includes a toilet seat movable part including a metal. The toilet seat is supported by the toilet seat movable part to be rotatable. The radio wave sensor is provided in an interior of the main part and uses a radio wave to detect a user in front of the main part. The radio wave sensor includes a controller that determines a state of the user and outputs a signal relating to a determination result. The toilet seat movable part opens and closes the toilet seat based on the signal. The controller is positioned further rearward than the toilet seat movable part. At least a part of the controller overlaps at least a part of the toilet seat movable part in a frontward/rearward direction.
