[0002] As a common kitchen appliance, the oven is mainly used for baking, roasting and cooking various foods. Its working principle is based on the heat generated by heating elements (such as electric heating tubes or gas burners), which transfers heat to food through heat conduction, convection and radiation. Modern ovens are usually equipped with temperature controllers and temperature sensors, which can accurately control the temperature inside the oven to ensure that the food is evenly heated and achieve the desired cooking effect.

[0003] For some relatively simple ovens, natural ventilation is relied on to discharge the smoke generated during the cooking process. This method is generally achieved through small holes in the oven door or top, using the air flow formed by the temperature difference between the inside and outside of the oven to naturally discharge the smoke. However, this method of smoke discharge is inefficient, especially when dealing with a large amount of smoke or long cooking time, it is difficult to effectively remove the smoke, which may lead to a decrease in kitchen air quality and even affect the health of the occupants.
