Therefore, even if the nichrome wire generates heat, there is a time delay due to the heating properties of magnesia before the temperature of the metal pipe increases and the oxidation catalyst is heated. In order to shorten this time, it is possible to increase the watt density of the nichrome wire, but in this case, the volume of magnesia must be increased to ensure insulation, which also makes the temperature rise of the metal pipe worse. , cannot be an effective solution.

A nichrome wire 16 as a heating element is disposed inside the catalyst 5, and is placed near the catalyst 11. Both upper and lower ends of the two vibrators 15 are projected outward through holes 17 formed on both upper and lower surfaces of the exhaust duct 10, and their upper ends are attached to a holding plate 18 attached to the upper surface of the exhaust duct 10. Fixed. An insulator 19 is attached to the upper end of the two vibrators 15, and each insulator 19 has a terminal 2 connected to the upper end of the nichrome wire 16 in each vibrator 15.
0 is attached. Note that the terminal 20 is connected to the power source via a lead wire (not shown). In addition, an insulator 2 is attached to the lower ends of the two vibrators 15 so as to straddle between the lower ends of the vibrator 15.
1 is installed, and each pipe 15 is attached to this insulator 21.
A connecting plate 22 is attached to connect the lower ends of the inner nichrome wires 16. In this case, a groove 21a that tapers downward is formed in the lower surface of the insulator 21, and the connecting plate 22 is disposed within this groove 21a.

なっている。On the other hand, on the rear side of the inner box 3, as shown in FIGS. 3 and 4, a heater 23 for oven cooking is arranged.
When the circulation fan 24 is rotated by the motor 25 during oven cooking, air heated by the heater 23 is supplied into the cooking chamber 2. Further, a heater 26 for grill cooking is arranged on the upper surface of the inner box 3, and the heat of this heater 26 is radiated into the cooking chamber 2.

気は触媒１１により分解除去される。In the above configuration, during oven cooking or grill cooking performed using the oven cooking heater 23 or the grill cooking heater 26, the nichrome wire 16 of the heater 12 of the deodorizing device 13 is energized to heat and activate the catalyst 11. At this time, when the nichrome wire 16 is energized and generates heat, the heat is directly conducted to the pipe 15 by radiation. As a result, the temperature of the pipe 15 immediately increases and begins to heat the catalyst 11, so that the catalyst 11 rises to the activation temperature in a short time. Thus, the odor contained in the air exhausted from the cooking chamber 2 to the outside through the exhaust duct 10 is decomposed and removed by the catalyst 11.

合は生じない。Incidentally, during microwave heating cooking performed by the magnetron 5, the nichrome wire 16 of the deodorizing device 13 is not energized, and therefore the catalyst 11 does not exhibit a deodorizing effect. During this microwave cooking, air containing moisture flows through the exhaust duct 10, but since both ends of the pipe 15 of the heater 12 protrude outside the exhaust duct 10, moisture does not enter into the pipe 15. . Therefore, there is no fear that dew condensation will occur on the nichrome wire 16 and the nichrome wire 16 will rust. Furthermore, when dew condensation occurs on the outer surface of the pipe 15, the water droplets flow down the pipe 15 to the insulator 21 on the lower side, but since the spanning plate 22 is provided in the groove 21a, the water droplets do not adhere to the spanning plate 22. Therefore, the problem of loss of insulation does not occur.
