Patent ID: 7267833

Claim:
An automatic buckwheat cooking apparatus, comprising: a cooking cavity that contains buckwheat to be cooked and water therein; a heating unit that heats the buckwheat and the water; a gas sensor that detects properties of air inside the cooking cavity; and a heat, simmer, steam control unit operated to automatically cook the buckwheat, a cooking time of a simmering stage depending on an amount of moisture generated in the simmering stage, and wherein the heat, simmer, steam control unit is arranged to control the heating unit to: heat the buckwheat and the water to boiling at an initial output of the heating unit for a first preset time, obtain an output of the gas sensor after the first preset time has elapsed, simmer the buckwheat and water at a first reduced output that is approximately 75% or 80% of the initial output for a period of about twice the first preset time or a maximum of about seven minutes, allowing heated temperature water to be absorbed into the buckwheat, and reduce the output of the heating unit to a second reduced output that is approximately 60% of the first reduced output and cook an inside of the buckwheat using the heated temperature water absorbed into the buckwheat when the output of the gas sensor reaches a preset value, wherein the output of the heating unit is reduced to the second reduced output if a current output of the gas sensor is equal to or less than 77% of an initial output of the gas sensor, and a uniform and optimal cooking quality of buckwheat is provided.
