A heat radiating fan 8 and a motor (not shown) for driving the heat radiating fan 8 are provided.
    An air duct 5 is provided in front of the magnetron 4 to guide the air introduced by the blowing fan 8 to the cooking chamber 9.
    The heat dissipation fan 8 installed at the rear side of the electric compartment 3 of the main body 1 has high heat generated by the magnetron 4 and the high-pressure transformer 6 through which air introduced into the air inlet (not shown) provided at the rear of the microwave oven is generated. In order to provide heat dissipation, a motor is provided on the rear side of the heat dissipation fan 8 to drive the heat dissipation fan 8.
    Most of the air blown by the heat radiating fan 6 is introduced through the air inlet hole 12 provided inside the cooking chamber 9 through the air duct 5 for guiding it to the cooking chamber 2, and then the cooking chamber. (9) is discharged to the outside of the cooking chamber 9 through the air discharge hole 13 provided in the side of the cooking chamber 9 together with the gas such as water vapor generated therein.
    A part of this air duct 5 is opened to the upper side of the cooking chamber 9 in order to prevent heat in the cooking chamber 9 from being transferred to the main body 1 so that a space between the outer case 1b and the inner case 1a is provided. After the air is put into the heat dissipation is discharged to the outside through the rear of the outer case (1b).
    External air is sucked through the heat dissipation fan 6 provided at the rear of the electrical equipment compartment 3 and blown to the electrical equipment compartment 3, and the blown air is upper side of the cooking chamber 9 and the cooking chamber 9 through the air duct 5. Is discharged. The external air introduced into the cooking chamber 2 through the air inlet hole 12 discharges water vapor or gas in the cooking chamber 2 to the outside of the cooking chamber 2 through the air discharge hole 13. The gas sensor 20 is provided in the side plate 2a of the cooking chamber 2 provided with the 13) to detect the cooking state of the air inside the cooking chamber 2. The gas sensor 20 is installed in the bracket (21) provided on the side plate (2a) for mounting.
    However, the gas sensor 20 is connected to the circuit board 23 coupled to the control unit 2 as a wire 22 passing through the outside of the cooking chamber 2, so that the assembly and installation work is not easy, and a separate bracket for mounting (21) had a difficulty to be prepared. As a result, assembling work requires a lot of work time due to the complicated mounting structure, and a separate part for mounting has to be prepared, thus reducing the manufacturing cost of the product.
    The present invention is to solve this problem, the object of the present invention is to change the mounting position of the gas sensor and the position of the heat dissipation fan mounted on the cooking chamber side plate of the microwave oven to improve the assembly and reduce the manufacturing cost of the microwave oven To provide.
