Touch key processing method and device and cooking utensil

The invention discloses a touch key processing method and device and a cooking utensil. The touch key processing method comprises the steps that a first difference value of a first key value generatedby a touch key and a reference value and a system threshold value are obtained, wherein the reference value is a key value generated when the touch key is not triggered; by comparing the first difference value with the system threshold value, whether or not the touch key is valid is judged; on the condition that the touch key is invalid, multiple difference value intervals and a threshold value adjustment mode corresponding to reach different value interval are obtained; the first difference value is matched with the multiple difference value intervals, and a threshold adjustment mode corresponding to the first difference value is obtained; the system threshold value is adjusted according to the threshold value adjustment mode corresponding to the first difference value, and an adjusted threshold value is obtaine
