In the above-mentioned technical solution, the combustion in the burner generates heat, and the motor drives the centrifugal fan to transport the heat to the hot air channel formed by the air deflector and the wall of the furnace cavity. The gap at the front end of the cavity wall flows inward, and finally circulates through the ventilation partition to the surroundings of the centrifugal fan to achieve the purpose of heating the food placed in the furnace. The air guide plate makes the distribution of hot air in the furnace more uniform.

Preferably, an air return plate is installed between the air deflector and the front end of the furnace cavity wall, the surface of the air return plate is provided with an elliptical air return hole, and the air return plate can adjust the wind speed at the corner of the hot air, Make the hot air circulation more even.

Preferably, fan-shaped circular ventilation holes are arranged on the surface of the ventilation partition. After the hot air heats the food in the oven cavity, it returns to the centrifugal fan and the hot air generated by the burner through the ventilation holes provided on the surface of the ventilation partition. Mix and continue the next cycle heating, realize the heat cycle use, and the energy saving effect is outstanding.

Preferably, an air guide hole is opened on the top of the air guide plate, and part of the circulating hot air can enter the furnace through the air guide hole opened on the air guide plate to bake food, so that the baking efficiency is higher.

Preferably, the air guide plate is welded by 5-10 air guide vanes and a connecting plate, and the air guide vanes can accelerate the hot air circulation rate, making the hot air circulation more efficient.

The beneficial effects of the oven hot air circulation system provided by the utility model are as follows: 1) The oven hot air circulation system uses a centrifugal fan to uniformly output the heat generated by the burner, and then distributes the hot air evenly in the oven through the air guide plate. In the wall of the gallbladder cavity, the baking is more uniform and the baking efficiency is improved; 2) The recycling of heat is realized, and the energy saving effect is good.
