The invention relates to an integrated cooker with a detachable energy-saving cover and relates to an integrated cooker. Since a conventional integrated cooker is of a side-suction bottom-exhaust type, flame of the cooker inclines towards a smoke suction opening, the heat efficiency of the combustion is reduced, and the contradiction between the heat efficiency and the smoke suction effect is difficult to solve. The integrated cooker comprises a side-suction range hood and a gas cooker, wherein the gas cooker is provided with a cradle, and the integrated cooker is characterized in that the detachable energy-saving cover is arranged on the cradle, and the energy-saving cover is of a semi-surrounding structure with an opening in the front side. According to the technical scheme, the side suction force of the range hood for the flame can be reduced and the heat efficiency of the gas cooker can be effectively improved; moreover, the front part of the energy-saving cover is provided with an opening, so that the air exchanging of the flame combustion is not influenced.
