At present, when the oven is used for baking food, a large amount of oil smoke is generated when the food is baked due to the existence of high temperature and oily food materials, the oil smoke generated when the food is oily is more, the oil smoke is dispersed into a kitchen to generate a pungent oil smoke taste, and meanwhile, the oil smoke is dispersed out of an oven cavity and also can be adhered to a cabinet and a dining table in the oven to cause trouble to use. Meanwhile, the generation of oil smoke in the cavity can make the cooking condition in the oven invisible to the user, which is a second pain point for the user. Therefore, when the existing oven is used for removing the oil smoke, a separate oil smoke removing module is generally arranged, and two hardware conditions are required to be realized: on the one hand, effective catalytic materials are needed; on the other hand, high temperature is required, and the catalytic material is generally made of honeycomb ceramic material as a base material, and noble metal is attached to the catalytic material to realize the catalytic effect. The high temperature is typically achieved by heating the catalytic material by a separate heating tube to effect catalysis. However, even if the arrangement mode has the effect of removing the oil fume, the space utilization rate of the oven is low, and correspondingly, the production cost is high.
