In order to ship the combined microwave oven as a product, a variety of tests are generally performed, one of which is a potato burning test. The potato burning test puts potatoes in the cavity 1 and operates the microwave oven at the highest power. In addition, smoke and gas are generated from the potato over time, and if the gas and smoke generated from the potato cannot be discharged to the outside of the microwave for a predetermined time, the fire may ignite, causing the gas to explode, and the door of the microwave oven may be opened or damaged. . The potato burning test is an inspection that must pass essentially as a mandatory standard for securing the safety of a microwave oven.

However, the following problems are pointed out in the hood-use microwave oven comprised in this way.

Since the distance between the inlet part 15 and the exhaust port 17 is far from the microwave oven, the air flow formed by the cooling fan 9 is cooled from the inlet part 15 to the exhaust port 17. It is pointed out that it is not affected by 9 and cannot be discharged to the outside smoothly.

In addition, for example, the gas and smoke generated in the potato burning test moves along the air introduced into the cavity 1 and is discharged to the outside. There is a disadvantage that can not be.

Accordingly, an object of the present invention is to solve the conventional problems as described above, and to provide a gas discharge structure of a combined use microwave oven that can smoothly discharge the flow of air introduced into the cavity to the outside of the microwave oven. .

Another object of the present invention is to provide a gas exhaust structure of a combined microwave oven that can smoothly discharge the gas generated in the cavity during food cooking to the outside of the microwave oven.
