This application relates to an intelligent drainage
system and method for a steam oven, including an
infrared water level sensor and a
humidity sensor installed inside the oven cavity. A control module is electrically connected to the
infrared water level sensor, the
humidity sensor, the bottom heating plate, and the drainage
assembly, and is used to: after cooking, determine whether there is residual water at the bottom of the cavity or on the
evaporation plate by using the residual
water level electrical
signal output by the
infrared water
level sensor; determine whether there is
residual moisture inside the cavity by using the detected cavity
humidity value and combining it with preset
moisture and humidity detection conditions; based on the determination results of residual water and / or
residual moisture, control the bottom heating plate to heat and evaporate the residual water and / or
residual moisture, and control the drainage
assembly to
discharge liquid water until the cavity humidity detected by the humidity sensor returns to a preset reference value. Through high-precision detection and
intelligent decision-making, the
system achieves accurate drainage and
evaporation of residual
moisture, improving the user experience and energy efficiency.
