Embodiment 1
[0018] Referring to Fig. 1, Fig. 2 and Fig. 3, a heating control system of an electrothermal film heater water dispenser includes a temperature sensor 1 located at the upper end of the electrothermal film heater inner cavity of the electrothermal film heater water dispenser, and a temperature sensor 1 located in the hot water The hot water discharge solenoid valve 2 used to control the hot water outlet on the water outlet pipeline, wherein the temperature sensor adopts a thermistor.
[0019] It also includes a temperature comparison module 3 that pre-stores the expected outlet water temperature and is used to compare the current temperature detected by the temperature sensor 1 with the expected outlet water temperature. The input end of the temperature comparison module 3 is connected to the temperature sensor 1, so The output end of the temperature comparison module 3 is connected to the hot water discharge solenoid valve 2 .
[0020] It also includes a temperature difference...
Embodiment 2
[0026] Referring to Fig. 2, Fig. 3, Fig. 4, in order to increase the temperature of the heated water as soon as possible when starting heating, the heating control system of the electrothermal film heater water dispenser also includes a function to make the electrothermal film heater The boost circuit 7 running at full power, in this embodiment, the boost circuit 7 selects a soft start circuit, and the soft start circuit is connected to the power supply 6 .
[0027] When the electrothermal film heating tube is turned on, the output voltage of the power supply 6 is adjusted in a soft start manner, so that the output power of the electrothermal film heater gradually increases until the full power output.
[0028] The temperature comparison module, the temperature difference calculation and comparison module, the power output control circuit and the boost circuit are integrated on the single-chip microcomputer. The rest of the structure and implementation are the same as in Embod...
