The heating bottom plate 6 and the heating top plate 7 arranged at the top and bottom inside the oven housing 1 and the heating wire 11 in the installation box 8 jointly form a circulating airflow environment, which is convenient for baking the food inside the oven housing 1. As the water mist spraying box 16 sprays water mist towards the direction of the high-temperature airflow flowing out of the heating wire 11, the water mist is vaporized to form steam to supplement the humidity inside the oven housing 1. Through the detection of the internal environment temperature of the oven by the first temperature measuring and protecting end 14 and the second temperature measuring and protecting end 15 arranged in multiple directions, the detection of the temperature inside the oven housing 1 is effectively improved. Cooperating with the oven controller 13 to regulate the temperature and humidity inside the furnace, the overall practicability is increased.
