Intelligent closestool

The invention provides an intelligent closestool. The intelligent closestool comprises a base, a hot water tank, a closestool cover and a closestool seat and further comprises a signal transmitter, a signal detector, a comparer and a heater, wherein the signal transmitter transmits a first signal at a specific frequency to environment; the signal detector receives a second signal reflected from the environment, converts the second signal into an electric signal and outputs the electric signal; a first input end of the comparer receives an electric signal output from the signal detector, a second input end receives a referential electric signal, when the electric signal level is larger than the referential electric signal level, the comparer outputs a high-level signal, and otherwise, the comparer outputs a low-level signal; the heater is arranged in a wall of the hot water tank, a control end of the heater receives a signal output by the comparer, and heating is started when the high-level signal is received
