In general, a cooking device is a device for cooking food by generating heat in a predetermined cooking space, and includes a microwave oven, a microwave oven, an oven, and the like.

Electric appliances such as magnetrons, high voltage capacitors, high voltage transformers, and convection / radiation heaters used in cooking generate a lot of heat during operation. At this time, if the electrical equipment is not sufficiently cooled, there is a high possibility that the cooker breaks down and malfunctions due to damage to the electrical equipment and damage to the electrical wiring. Therefore, in general, a cooking apparatus includes a cooling fan for generating a flow for cooling the electrical equipment and a cooling flow path formed by the flow generated by the cooling fan. At this time, the faster the flow rate, the better the cooling performance of the cooling channel.
