The invention discloses an
intelligent control method for the steam quantity and the cavity temperature field of an electric steamer. An
evaporation heater, an auxiliary heater and a temperature sensor are arranged in the electric steamer. The method comprises the following steps: S1, acquiring the maximum allowable use power of the
evaporation heater and the target temperature and the cooking time in the current working mode; S2, starting an
evaporation heater and adjusting power by adopting a PID
algorithm to obtain average power; S3, operating at the
actual use power and adjusting by adopting a PID
algorithm, when the
operation time reaches the cooking time, ending cooking, and otherwise, executing S4; and S4, judging whether the current temperature in the cavity reaches the target temperature or not, if so, returning to execute S3, otherwise, starting the auxiliary heater, adjusting and correcting the
actual use power of the evaporation heater by adopting a PID
algorithm, and returning to execute S3. According to the method, accurate control over the steam amount and the temperature field is considered, the water
utilization rate is increased, overflow and dry burning are avoided, the experience feeling is good, the
development period is short, cost is low, and universality is good.
