The invention discloses an integrated oven, comprising an oven table, an air suctioning baffle, a burning system and an air channel, wherein the air suctioning baffle is arranged at the upper part of the oven table; the burning system is arranged below the oven table; the air channel is communicated with the air suctioning opening of the air suctioning plate; the air channel comprises an air suctioning chamber, a turbine fan, an air outlet elbow and an air outlet pipe which are connected in sequence; a first oil collecting nozzle is arranged at the outer wall of the bottom side of the air outlet elbow; an inclined oil collecting plate is arranged below the first oil collecting nozzle; the lowest part of the oil collecting plate is provided with a gap; and a drawer-type oil collecting discis arranged below the gap. In the integrated oven disclosed by the invention, the whole structure is simple, and since the first oil collecting nozzle, a second oil collecting nozzle and a third oil collecting nozzle are arranged, the capability of timely discharging and collecting oil stains formed in the air channel is guaranteed, and the corrosion of the oil stains to pipelines and the pollution of the oil stains to the environment are prevented. In addition, as an air curtain mechanism is arranged, the diffusion of oily smoke is prevented and further the air suctioning effect of the integrated oven is improved.
