加熱器を汚す恐れもある。Problems to be Solved by the Invention Conventional examples mainly focus on natural exhaust based on the drift effect of the exhaust stack, and do not provide any specific description regarding forced exhaust. Natural exhaust alone poses various problems. One is that it is very difficult to exhaust all the large amount of oil smoke generated from food during cooking. Therefore, the heating chamber is filled with oily smoke, which flows out through gaps between various parts of the heating chamber, and the gas purification catalyst may become ineffective. The second problem is that when the food is taken out after cooking is finished, oily smoke inside the heating chamber blows out from the food take-out opening.
There is also the risk of contaminating the heater.

ーズヒータで構成されており、第２図に示すように曲面
で接するように取り付けられている。The main body exhaust port 12 is covered with an exhaust cover 13. A stepped portion 14 is provided on the front side of the main body at the upper part of the main body exhaust port 12 on the rear surface of the main body. A control section 16 that controls the heaters 4 and 6, the auxiliary heater 9, the motor 1o, and the like is provided at the upper front surface of the heating chamber 2. Note that the auxiliary heater 9 is constituted by a sheathed heater, and is attached so as to be in contact with a curved surface as shown in FIG.
加熱室２の側壁面には非粘着性塗膜１６がほどこされて
いる。A non-adhesive coating film 16 is applied to the side wall surface of the heating chamber 2.
浄化触媒８は安定な構造で耐熱性の高いペロプスカイト
型複合酸化触媒をセラミックなどに担持させたものであ
る。The purification catalyst 8 is a perovskite type composite oxidation catalyst which has a stable structure and high heat resistance and is supported on ceramic or the like.

多数の穴を通過して浄化され、加熱調理器の外に排出さ
れる。このとき新しい空気はドア３と加熱室２の隙間か
ら供給−れる。排出された排気の成分は二酸化炭素と水
蒸気である。With this configuration, the oil smoke generated from the food 1 is sucked in by the sirocco fan 11, exhausted from the exhaust port 6, and purified by passing through the many holes of the purification catalyst 8 heated by the auxiliary heater 94C. , is discharged outside the cooking device. At this time, new air is supplied from the gap between the door 3 and the heating chamber 2. The components of the emitted exhaust gas are carbon dioxide and water vapor.
それらの排気は排気カバー１３により方向を上部に変え
られて排出される。さらに、段部１４が設けられている
ため排気の方向は前側に向けられる。The direction of these exhaust gases is changed upward by the exhaust cover 13 and the exhaust gas is discharged. Furthermore, since the stepped portion 14 is provided, the direction of exhaust gas is directed to the front side.
以上のように、強制排気により排気が充分にできるとと
もに触媒８の前側にシーズヒータを使用した補助ヒータ
９を密着させる構成で有るため、触媒８を充分に加熱す

。従って、シロッコファン１１を通過する空気は水蒸気
が主であり、シロッコファン１１には汚れが付着しにく
いため、ファンのバランスが崩れることがなくモータの
耐久性も問題なくなる。As described above, since the forced exhaust allows sufficient exhaust air and the auxiliary heater 9 using a sheathed heater is placed in close contact with the front side of the catalyst 8, it is possible to sufficiently heat the catalyst 8 and purify oil smoke etc. The ability is fully developed. Therefore, the air passing through the sirocco fan 11 is mainly water vapor, and dirt does not easily adhere to the sirocco fan 11, so the balance of the fan will not be lost and the durability of the motor will not be a problem.
補助ヒータ９は触媒８と曲面で接するため触媒に設けら
れた多数の穴を塞ぐことがなく触媒を有効に活用できる
。また、触媒に対しヒータの輻射面が広く取れるため触
媒を局部的に加熱することがない。また、ペロブスカイ
ト型酸化触媒を使用しているため耐熱性が高く、浄化能
力の劣化も問題ない。Since the auxiliary heater 9 contacts the catalyst 8 with a curved surface, the catalyst can be used effectively without blocking the many holes provided in the catalyst. Furthermore, since the radiating surface of the heater is wide relative to the catalyst, the catalyst is not locally heated. Additionally, since it uses a perovskite oxidation catalyst, it has high heat resistance and there is no problem with deterioration of purification ability.
ドア３からは常に新鮮な空気が流入する構成であるため
いかに加熱室２内に煙が充満してもドア３の周囲から漏
れることがなく、使用者に不快感を与えたり、加熱調理
器の前面を汚す心配がない。Since fresh air always flows in from the door 3, no matter how much smoke fills the heating chamber 2, it will not leak from around the door 3, causing discomfort to the user or damaging the heating cooker. No need to worry about getting the front dirty.
吸気はドア３の周囲からしか行わないため吸気抵抗は高
いが、圧力の高いシロッコファン１１を使用することに
より充分に吸気および排気が可能となる。Since air is taken in only from around the door 3, the air intake resistance is high, but by using the high-pressure sirocco fan 11, sufficient air can be taken in and exhausted.
加熱室２の側壁面には非粘着性塗膜１６が施されている
ため、油煙等が付着しにくいが、しかも、強制排気を行
っているためさらに油煙などの付着がなくなる。このこ
とによりより一層清潔さを維持できるものである。Since the side wall surface of the heating chamber 2 is coated with a non-adhesive coating film 16, it is difficult for oil smoke etc. to adhere, but since forced exhaust is performed, the adhesion of oil smoke etc. is further eliminated. This makes it possible to maintain even greater cleanliness.
なお、触媒はペロプスカイト型複合化合物に限定するも
のでなく他の材料でも使用可能なことは言うまでもない
。It goes without saying that the catalyst is not limited to the perovskite type composite compound, and other materials can also be used.
補助ヒータ９はシーズヒータで構成されているため、食
品から発生する、塩分、水分などが集中する排気通路内
においても、腐食などの心配がなく低コストで高い信頼
性が得られる。Since the auxiliary heater 9 is constituted by a sheathed heater, there is no fear of corrosion even in the exhaust passage where salt, moisture, etc. generated from food are concentrated, and high reliability can be obtained at low cost.
排気通路７は立体的に構成しているため加熱室後部の寸
法は小さくてすみ、コンパクトな加熱調理器が構成でき
る。Since the exhaust passage 7 is structured three-dimensionally, the rear part of the heating chamber can be small in size, and a compact cooking device can be constructed.
加熱調理器の排気口１２から出た排気は排気カバー１３
により上方に方向を変更され、さらに段部１４により、
本体の前側に排気の方向を変えられるため、加熱調理器
が設置された後方の壁には排気が直接吹きつけることが
ないため、水蒸気などでぬれることがない。The exhaust gas coming out from the exhaust port 12 of the heating cooker is passed through the exhaust cover 13.
The direction is changed upward by the step part 14, and further by the step part 14,
Since the direction of the exhaust air can be changed to the front of the main unit, the wall behind the heating cooker is not directly blown by the exhaust air, so it does not become wet with water vapor.
