Claim Text:
1. A water-saving type toilet stool including an intermediate reservoir, comprising: a toilet stool main body that includes a receiving portion on which a user may sit to relieve oneself and in which excrement of the user is temporarily stored, a water supply flow path through which water is supplied to the receiving portion, and a discharge outlet that is formed at a lower portion of the receiving portion so as to discharge the excrement stored in the receiving portion; a manipulation button that is formed to be pressed by the user to discharge the excrement stored in the receiving portion to the discharge outlet; a control unit that receives a signal of the manipulation button; a water supply unit that is operated via the manipulation button to supply water to the water supply flow path of the toilet stool main body so as to discharge the excrement contained in the receiving portion through the discharge outlet; a discharging unit that comprises a discharge valve that is installed at the discharge outlet of the toilet stool main body and is operated by using the control unit to open or close the discharge outlet of the toilet stool main body and a discharge pipe that is connected to the discharge outlet to transfer excrement and water discharged through the discharge outlet when the discharge outlet is opened via the discharge valve; and an intermediate reservoir unit that comprises an intermediate reservoir that is connected to the discharge pipe of the discharging unit, is disposed below the toilet stool main body, includes an inlet through which the excrement discharged through the discharge pipe flows, and stores the excrement, a rotational axis that rotatably supports the intermediate reservoir such that the intermediate reservoir rotates due to a self-weight of the intermediate reservoir to discharge the excrement at a time when the intermediate reservoir is fully filled with the excrement after using the toilet stool main body a plurality of times, and a connection pipe that connects the intermediate reservoir and a piping so as to transfer the excrement to the piping that is connected to a septic tank of the building as the intermediate reservoir rotates to discharge the excrement stored in the intermediate reservoir, wherein the discharge valve of the discharging unit comprises a closing/opening member that is rotatably installed in the discharge pipe and a closing/opening motor that opens or closes the discharge outlet by rotating the opening/closing member, wherein the intermediate reservoir unit further comprises a first sealing member that is formed in the form of a corrugated pipe and closely seals space between the discharge pipe of the discharging unit and the inlet of the intermediate reservoir from the outside and connects the discharge pipe of the discharging unit and the inlet of the intermediate reservoir even when the intermediate reservoir rotates.
