The air inlet pipe and the air outlet pipe are provided with a matching sealing plate, and the sealing plate is connected with one end of the connecting shaft arranged on the box body. The other end of the connecting shaft is also provided with an adjustment handle, and a motor is provided on the top plate of the box between the air inlet pipe and the air outlet pipe, and the rotating shaft of the motor extends downward to the air outlet on the upper supporting plate in the inner box. Inside the pan, a through-air fan is arranged on the motor shaft in the wind pan, and a plurality of guide plates are set at the air outlet of the wind pan facing the heater.

Specifically, a handle is provided on the left door.

Specifically, a lower supporting plate is arranged on the bottom plate of the box body.

Specifically, a trigger is provided on the connecting rod.

The design of the utility model, compared with the prior art, transfers the heat generated by the heater to the inner box in the form of wind for heating through the circulating air supply mode of the fan, and the through-air fan blows the recovered hot air to the surface of the heater again For heating, because the wind circulates in the way of left and right convection, it can be blown to various spatial positions of the inner box to avoid the problem of uneven temperature and improve product quality. The hot air circulation method achieves fast electric heat conduction and the heater is recycled and reused, saving energy. Energy improves production efficiency, improves the reliability of equipment such as ovens, and has better practicability.

detailed description

As shown in the figure, an oven hot air heating structure includes a box body 14, the left and right sides of the bottom plate of the box body 14 are provided with mounting seats 10, the front side of the box body 14 is provided with a left door 22 and a right door 23, and the right side The door 23 is provided with a bracket 6, and the bracket 6 is provided with a connecting rod 7, and the upper and lower ends of the connecting rod 7 are provided with stoppers 9, and the stoppers 9 correspond to the stoppers 5 arranged on the casing 14.

In the box body 14, an inner box body 19 is provided, and a filter plate 17 is arranged in the inner box body 19. An air inlet pipe 3 and an air outlet pipe 2 connected thereto are arranged on the top plate of the inner box body 19. The inner box body 19 is provided with a heater 15 corresponding thereto. The upper ends of the air inlet pipe 3 and the air outlet pipe 2 extend upwards through the top plate of the box body 14 to communicate with the outside world. Cooperating sealing plate 11, the sealing plate 11 is connected with one end of the connecting shaft 12 arranged on the box body 14, and the other end of the connecting shaft 12 is also provided with an adjustment handle 13, the air inlet pipe 3 and the air outlet pipe 2 between A motor 1 is arranged on the top plate of the box body 14 , and the rotating shaft of the motor 1 extends downward into the wind pan 20 on the upper supporting plate 24 in the inner box body 14 , and the shaft of the motor 1 in the wind pan 20 is provided with a through-air fan 16 The air tray 20 is provided with a plurality of guide plates 21 towards the air outlet of the heater 15, and the wind blown by the through-air fan 16 can evenly contact the heater 15, so that the temperature of the wind passing through the heater 15 is the same.

Left side door 22 is provided with handle 4, convenient to open.

A lower supporting plate 18 is arranged on the bottom plate of the box body 14 .
