A water urinal has a urinal body which includes a housing with an opening on its upper portion for receiving a valve used to supply flushing water to the urinal. The valve is attractively concealed within the body of the urinal and eliminates the necessity of embedding a valve in the wall surface on which the urinal is mounted. A cover, which covers and provides access to the valve receiving space within the urinal body, allows maintenance of the urinal without having to remove the urinal from the wall or break an opening in the wall.

Water urinal

This invention relates to a lavatory hopper flushing apparatus, particularly, a lavatory hopper flushing apparatus comprising a sensor unit capable of detecting the use of any one of a plurality of lavatory hoppers arranged side by side, and providing a detection signal upon the detection of the use of any one of the lavatory hoppers; a control unit capable of being actuated by the detection signal; and a water supply unit capable of being driven by the control unit so as to flush all the lavatory hoppers simultaneously; wherein the control unit capable of being actuated by the detection signal given by a sensor unit and driving a water supply unit includes a counter control unit which has a counting circuit that counts the frequency of the detection signal and which provides an output signal when the count of the detection signals reaches a predetermined number, and an output control unit which provides an output signal to actuate the water supply unit, upon the reception of the output signal given by the counter control unit, whereby all the lavatory hoppers of a group is simultaneously flushed with water when the total number of times of the use of the lavatory hoppers of the group reaches a predetermined number.
