く高められる。(E) Function Since the electric heater is sandwiched between the first and second catalysts in a sealed state, the heat of the electric heater is difficult to escape to the outside, and the electric heater evenly covers the first and second catalysts. Heat. Therefore, the purification effects of the first and second catalysts are uniformly enhanced.
また、電気ヒータは、密封された状態にあって浄化され
るガスに晒されず、劣化しにくい。Moreover, the electric heater is in a sealed state and is not exposed to the gas to be purified, so that it is less susceptible to deterioration.

These legs are made of butylene and have hemispherical recesses 3.3. These recesses are
It acts as a suction cup and suppresses the cooking device main body 1 from undesirably moving when it is placed on the stand 4. Inside the cooking device main body 1, microwave heating, oven heating,
A heating chamber 5 in which grill heating is performed is arranged, an exhaust air passage 6 is connected to this heating chamber, and a catalyst device 7 is detachably housed in this exhaust air passage.

がない密封状態に保たれている。2 and 3 show details of this catalyst device 7. FIG. The catalyst device 7 includes a meandering electric heater 8 and first and second oxidation catalysts 10, 11 that are heated by the electric heater and have a large number of small holes 9, 9 through which gas passes. Become. The first and second oxidation catalysts 10.11 sandwich the electric heater 8,
Moreover, the first oxidation catalyst 10 is fitted into the second oxidation catalyst 11, and in this case, the electric heater 8 is kept in a sealed state so that it does not come into contact with the gas to be purified.
