Abstract
An improved cooking apparatus or cooker which heats and cooks food items in a cooking liquid medium by effectively controlling the temperature of the liquid medium. The cooker starts forcible combustion irrespective of the temperature of the liquid medium detected by a temperature sensor when the operator presses a forcible combustion switch. This system minimizes a time lag between placing food items into the cooking liquid medium and start of combustion, which is attributable to the uneven temperature distribution and convection of the cooking liquid medium, thus efficiently reducing undesirable temperature drop of the cooking liquid medium due to cold food items. Alternatively, the cooker determines presence of food items in the cooking liquid medium according to the downward slope in temperature instead of a press of the forcible combustion switch and automatically starts forcible combustion.
