A method and a device for controlling a heating temperature of an electric rice cooker and the electric rice cooker. The control method comprises: when determining that the electric rice cooker is in a boiling state, according to a temperature of a bottom temperature sensing bulb and a temperature of a top temperature sensing bulb, judging whether a bottom temperature of the electric rice cooker rises too fast (S110), when determining that the bottom temperature rises too fast, controlling a heating plate to temporally stop heating the bottom of the electric rice cooker (S120); and after the temperature of the bottom temperature sensing bulb falls to a first preset temperature, controlling the heating plate to reheat the bottom at a heating power in the boiling stage (S130).
