The invention discloses an intelligent water dispenser. According to the intelligent water dispenser, a temperature sensor transmits a real-time water temperature signal to a temperature sensing controller, the real-time water temperature signal processed by the temperature sensing controller is then output to a nixie tube to be displayed, the temperature sensing controller is in signal connection with a main controller, the signal output end of the main controller is connected with a main switch, a relay and a heating unit in series and in sequence to form a heating control closed loop circuit, the main controller compares the received real-time water temperature signal with a set water temperature received by the main controller and input by a user, if the real-time water temperature is lower than the set water temperature, the main controller controls the relay to be started, the heating control closed loop circuit is made to be in the on-state, the heating unit starts to heat the water in the liner of the water dispenser, and if the real-time water temperature is not lower than the set water temperature, the main controller controls the relay to be shut down, and the heating unit stops heating the water in the liner of the water dispenser. According to the intelligent water dispenser, different requirements of the user can be met, energy waste can be effectively reduced through preference setting, the safety of using of the water dispenser can be guaranteed, and the service life of the water dispenser can be prolonged.
