As shown in
In this embodiment, the voltage variation of the heating part 51 during the heating process is controlled by varying PWM to improve a temperature uniformity of the heating solution and an accuracy of temperature detection.
Specifically, during the T1 period, the duty cycle of the voltage of the PWM-controlled heating part 51 is slowly increasing, during which the heating rate of the heating piece is slower, and the temperature rises slower. This facilitates the temperature to conduct and improve the initial temperature uniformity, which allows the temperature detected by the temperature detection device 6 to be close to the temperature of the overall solution in the baby bottle.
Excessive heating rate at the beginning will make the temperature difference between different positions of the solution too large. Considering that the heat conduction needs a certain period of time, if the heating rate is greater than the rate of the heat conduction, a large temperature difference will occur between the part away from the heating point and the part near the heating point, thereby failing to achieve the uniform heating.
At the T2 period, at this time, after heating at a low power in T1 stage, the overall temperature of the solution is increased and the temperature is uniform, and the temperature detected by the temperature detection device 6 is accurate. At this point, full-power heating (PWM duty cycle of 100%) is started at the T2 stage, which increases the heating rate and does not have to worry about excessive temperature differences within the heated solution. At this time, through the overall temperature of the solution has been increased, and the heating power is constant, so that the heated solution will not produce too large a temperature difference which is constant within the solution.
At the T3 period, when the solution in the baby bottle is close to the set heating temperature, it is heated again at a low-power to reduce the rate of temperature rise, so that the temperature in the solution is uniformly conducted to further improve the consistency of the overall temperature. And at the same time, it can also improve the detecting accuracy of the temperature detection device 6, and further improve the taste of the baby.
Described above are only preferred embodiments of the present disclosure, which are not intended to limit the scope of the present disclosure. It should be understood that various changes, modifications and replacements made by those skilled in the art without departing from the spirit of the disclosure shall fall within the scope of the disclosure defined by the appended claims.
