The high-temperature hot air is blown away to form an air flow line, thereby achieving the cooling effect.

Two layers of heat insulation boards are also arranged between the reflection cover and the box body of the heating chamber, and there are gaps between the reflection cover and the heat insulation boards, and between the heat insulation boards and the heat insulation boards to form a cooling space. The wind blown by the fan assembly to the magnetron is guided to the outside of the heating chamber, and the heat generated in the heating chamber is brought to the cooling space. After layers of heat insulation, the heat is already very weak when it is transferred to the outside of the box, thereby achieving the cooling effect . The utility model does not need to add other devices dedicated to heat dissipation, thereby controlling the increase of the cost of the whole machine, which is beneficial to saving product development costs, and can achieve an ideal cooling effect.
