The main body of the above-mentioned air guiding pipe and its one end and the other end are integrally made, or the main body of the air guiding pipe, its one end and the other end are made separately, and then connected together.

The above heating pipe cover is made separately, and then fixed on the top of the casing; or the heating pipe cover is directly made integrally with the casing.

The above-mentioned fan is a cooling fan of the microwave generating device, or a special fan.

The above-mentioned heating tube is a quartz tube or a halogen tube or a metal electric heating tube, or includes a quartz tube and a halogen tube, or includes a metal electric heating tube and a halogen tube, or includes a quartz tube, a halogen tube and a metal electric heating tube; the above-mentioned heating tube is made of Out as a straight line, or as a curved type.

The bottom of the above-mentioned heating pipe cover has an opening, and the opening communicates with the cavity surrounded by the shell; The formed cavities are connected.

Because the utility model adopts the structure that the opening at one end of the air guide pipe communicates with the hollow cavity of the heating pipe cover, and the other end of the air guide pipe is placed at a position corresponding to the fan, the air guide pipe close to the cooling fan can be separated from the cooling fan. A part of the blown wind is blown through the heating pipe, and the heat of the heating pipe is brought into the cavity of the microwave oven through the top and the side of the casing, so as to promote the formation of air convection in the cavity. Therefore, the utility model can not only accelerate the temperature rise of the furnace chamber, but also provide cooling protection for the heat pipe and its surrounding components, reduce the temperature requirements of the components, prolong their service life, and the air source can be directly driven by the cooling motor. cooling fan. The utility model is a microwave oven with ingenious design, simple structure, low cost, good effect and barbecue function.
