The invention discloses a closestool. The closestool comprises a closestool base and a flushing device, wherein the flushing device comprises a controller, a nozzle mechanism and a first imaging device. The controller controls the operation of the nozzle mechanism according to user's hips imaging information fed back by the first imaging device; the nozzle mechanism sprays water to the hips of a user so as to achieve body cleaning; the first imaging device obtains the user's hips imaging information so as to make the controller automatically judge whether the hips of the user are rinsed thoroughly or not, automatic cleaning of the hips of the user is achieved, the reliability of the body cleaning is guaranteed, and the closestool is convenient to use. According to the control method of the closestool, the controller judges whether foreign matter appears on the hips of the user or not, and correspondingly controls the nozzle mechanism to continue body cleaning or stop body cleaning; the intelligent level is high, and the hygiene property and the water saving ability are both taken into consideration. According to the control method of the closestool, the controller controls a second imaging device to conduct imaging on a urinal, judges whether it is excrement or urine, and then controls the flushing device to flush the closestool with a corresponding quantity of water. By means of the closestool, flushing with the corresponding quantity of water can be achieved according to the corresponding excrement or urine, and the cleaning of the closestool and water conservation are both taken into consideration.
