Hot air circulation type baking machine

The invention discloses a hot air circulation type baking machine, which comprises a notch, a machine body, a door body and a fixing plate. The notch is formed in the machine body, a hinge is installed on the outer side wall of the notch, and the door body is movably connected to the outer side wall of the hinge. The electric heating wires installed on the inner wall of the notch are controlled and started through a control switch to conduct heating work, the electric heating wires are evenly arranged on the inner wall of the notch at equal intervals, the interior of the notch is rapidly and evenly heated, in the working process, the control switch controls a first draught fan and a second draught fan installed at the bottom end of the notch to work according to needs, high-temperature air flow is formed through heating of the electric heating wires in the notch, materials on an inner filter screen disc are baked and air-dried at a high speed, the air flow can be pumped into a communicating pipe through an air pump installed at the top end of the notch in the blowing process, then the air flows into the notch from the two sides of the notch through a fixing groove, high-temperature wind in the notch is always in a flowing process, and thus the baking is more efficient and faster.
