The invention discloses an electric heating cooking appliance with a wireless steam detection device, which is a detection device for detecting the temperature, humidity, flow velocity and flow data signals of the steam flowing into the atmosphere through the pot cover in different boiling states of the liquid with wireless transmission and reception. On the pot lid of the electric cooking appliance that is detachable from the pot body or utensils and has no signal transmission wires, this effectively solves the problem that the pot lid and the pot body or utensils can be separated. The electrothermal liquid heating appliance is susceptible to product structure, heating method, and material changes , use environment, operation method, aging deformation, commercial pots of different specifications, etc., especially the changes in altitude, which cause existing problems such as electric rice cookers, electric pressure cookers, electric steamers, and electric stew pots. It has realized the intelligent judgment, adjustment and control of the cooking process when the electric heating stoves such as induction cooker, electric ceramic stove, health pot, electric tea set, and light-wave oven are performing the function of "steaming, cooking, and stewing".
