The invention provides an integrated oven and belongs to the field of articles for daily use. According to the integrated oven, the problem that an oil-filter screen cover of an existing integrated oven is inconvenient to replace is solved. The integrated oven comprises a shell, a draught fan installed in the shell and an oven table installed on the shell; a smoke discharging channel with an inlet and an outlet is formed in the shell which comprises a supporting wall being in a tabulate shape, an oil-filter screen being in a tabular shape is attached to the front side of the supporting wall, and the inlet of the smoke discharging channel communicates with the outside world through filtration holes in the oil-filter screen; a clamping piece being in a long-piece shape is installed between the supporting wall and the oven table, the oil-filter screen is clamped between the clamping piece and the supporting wall, and the clamping piece can move forwards and backwards relative to the oven table; a threaded hole directly facing the middle of the clamping piece is formed in the oven table, a screw is connected with the threaded hole in an internally threaded mode, and the front end and the rear end of the screw both stretch out of the threaded hole; and the rear end of the screw is rotatably connected with the clamping piece through a bearing. The integrated oven has the advantages of being convenient to replace the oil-filter screen.
