Apparatus for automatically treating excrement and controlling method thereof

A method of controlling an apparatus for automatically treating excrement that includes a mounting unit for receiving excrement of a patient, a control device unit including a washing water supply unit configured to supply washing water to a bidet on the mounting unit, and a washing water supply path connected from the washing water supply unit to the mounting unit, the method comprising:

• treating excrement by operating, by a controller, a reversible pump included in the washing water supply unit in a forward direction such that the washing water is emitted from the bidet;
• and
• operating, by the controller, the reversible pump in a reverse direction opposite to the forward direction for a set time after the excrement has been treated, such that residual washing water in the washing water supply path is collected in the washing water storage tank,
• wherein the forward direction is a supply direction.

An apparatus, comprising:

• an excrement receiving unit;
• an excrement tank coupled between the excrement receiving unit and a vacuum pump;
• a water storage tank storing washing water;
• a reversible pump coupled between the water storage tank and the excrement receiving unit, the reversible pump configured to pump the washing water out of the water storage tank when operating in a forward direction, and to pump residual water into the water storage tank when operating in a reverse direction;
• a controller configured to operate the reversible pump in the forward direction or the reverse direction;
• and
• an instantaneous water heater coupled between the reversible pump and the excrement receiving unit,
• wherein, when excrement is sensed in the mounting unit, the controller begins a treatment operation by operating the reversible pump in the forward direction such that the washing water is emitted from the bidet, and
• wherein, when the treatment operation is completed, the controller begins a collection operation by operating the reversible pump in the reverse direction for a set time, such that the residual washing water is collected in the washing water storage tank.
