【考案の詳細な説明】
本考案はヒータ付電子レンジの冷却に関するものである
。[Detailed Description of the Invention] The present invention relates to cooling of a microwave oven with a heater.
電子レンジは高周波で加熱室内の食品を選択的に加熱す
るので加熱室内の温度はさほど上昇せず、効率のよい調
理器具である。Microwave ovens selectively heat the food inside the heating chamber using high frequency waves, so the temperature inside the heating chamber does not rise much, making it an efficient cooking appliance.
しかし反面、パンやグラタン等の焦げ目がつく必要のあ
る、いわゆるオーブン料理はある程度、加熱室の温度を
上げる必要があり、高周波加熱では不可能であった。However, on the other hand, so-called oven dishes that require browning of bread, gratin, etc. require the temperature of the heating chamber to be raised to a certain degree, which is not possible with high-frequency heating.
その欠点を解消するたために庫内にシーズヒータ等の発
熱体を設置してオーブン料理を可能にしたヒータ付電子
レンジが考えられる。In order to overcome this drawback, a microwave oven with a heater has been considered in which a heating element such as a sheathed heater is installed inside the oven to enable oven cooking.
しかし庫内が高温になるため、オーブンとして使用した
後も庫内は高温のままである。However, because the temperature inside the oven is high, the interior remains hot even after being used as an oven.
一般に電子レンジはマクネトロンの冷却風を庫内に導い
て電子レンジ調理時に庫内が食品からの湿気でくもった
り、水滴が露結したりするのを防いでいる。Generally, microwave ovens guide cooling air from the Macnetron into the oven to prevent the interior from becoming cloudy with moisture from food and from forming water droplets during microwave cooking.
したがってそれを利用して本考案はオーブン料理終了後
、一定時間、マグネトロン冷却用のファンモータを回転
させ、その風でオーブン庫内を冷却させる回路を実現す
るものである。Therefore, by utilizing this, the present invention realizes a circuit that rotates a magnetron cooling fan motor for a certain period of time after the end of oven cooking, and uses the wind to cool the inside of the oven.
以下図に基いて、上記動作を実現させる回路を説明する
。A circuit that realizes the above operation will be explained below based on the drawings.
１は高周波加熱回路とヒータ加熱回路の切換スイッチで
あり、高周波加熱用のタイムスイッチを回すことによっ
て接点２がＮｏ側に入りオーブンランプ３が点灯する。Reference numeral 1 designates a changeover switch between the high frequency heating circuit and the heater heating circuit, and by turning the time switch for high frequency heating, the contact 2 enters the No side and the oven lamp 3 is turned on.
ドアが閉じられてドアスイッチ４の接点がＮＣ側に入る
とタイマーモータ５が動き出し、調理ボタンが押されて
ラッチスイッチ６が閉じるとマグネトロン７の冷却用の
ファンモータ８が回転し、トランス９の二次側に高電圧
がかかり、マグネトロン７が発振する。When the door is closed and the contact point of the door switch 4 enters the NC side, the timer motor 5 starts to operate, and when the cooking button is pressed and the latch switch 6 is closed, the fan motor 8 for cooling the magnetron 7 rotates, and the transformer 9 is turned on. A high voltage is applied to the secondary side, causing the magnetron 7 to oscillate.
一方、切換スイッチをＮｏ側に入れヒータ１０用のゼン
マイ式のタイマー１１を廻すと接点がＮｏ側に入りヒー
タに通電される。On the other hand, when the changeover switch is turned to the No side and the spring-type timer 11 for the heater 10 is turned, the contact is turned to the No side and the heater is energized.
このゼンマイ式のタイマーは一接点あたり三つの異なる
状態を取り、時間が経過して接点がオフになった時、パ
ワーリレー１２のコイルの両端に電圧がかかり、接点が
Ｎｏ側に入りファンモータが廻り、ファンの回転によっ
て起こされた風によって庫内の熱が追に出されてオーブ
ン庫内が冷やかれ、一定時間後接点はＮＣ側に入り、電
源が切れる。This wind-up timer has three different states per contact, and when the contact turns off after a period of time, voltage is applied to both ends of the coil of the power relay 12, and the contact enters the No side, turning the fan motor on. As the oven rotates, the air generated by the rotation of the fan dissipates the heat inside the oven and cools the oven interior. After a certain period of time, the contact goes to the NC side and the power is turned off.
このようにすることによってオーブン料理終了後、すみ
やかに庫内を冷却することができ、熱伝導によりかなり
あつくなっているドアの把手以外の金属部等に触れてや
けどをするという危険を防止できる。By doing this, the inside of the oven can be cooled down quickly after cooking in the oven, and the risk of getting burned by touching metal parts other than the door handle, which are quite hot due to heat conduction, can be prevented.
特に電子レンジとして使用する時に、庫内の温度もさほ
ど上がらず、一方オーブンとして使用した後しばらくは
ドアの把手以外の金属部等に誤まって触れるとやけどの
恐れがあるので、この冷却方式はヒータ付電子レンジに
おいては特に有効である。Especially when used as a microwave oven, the temperature inside the oven does not rise that much, and on the other hand, there is a risk of burns if you accidentally touch a metal part other than the door handle for a while after using it as an oven, so this cooling method is recommended. This is particularly effective in microwave ovens with heaters.
またオーブン料理の中にはシュークリームの皮やスポン
ジケーキのように、調理後すぐにドアを開けるとふくら
みがなくなるような物であるので、それらの料理を考慮
して、調理終了後、一旦ドアを開けた後ファンモータが
回転するようにすることもオフ接点とパワーリレーのコ
イルの間にドアースイッチに連動したスイッチを入れる
ことによって可能である。In addition, some oven dishes, such as cream puff pastries and sponge cakes, will not rise if the door is opened immediately after cooking, so please take these types of dishes into consideration and close the door once after cooking is complete. It is also possible to make the fan motor rotate after opening the door by inserting a switch linked to the door switch between the off contact and the power relay coil.
上記の冷却はマグネトロン冷却用のファンモータを使用
するものであり、新たなファンモータを必要とせず、ま
たマグネトロンの冷却風は電子レンジとして使用時も庫
内に入れてドアのくもり止めに使われており、オーブン
使用時は庫内温度を維持するためにファンモータは止ま
っている。The above cooling uses a fan motor for cooling the magnetron, so there is no need for a new fan motor, and the cooling air from the magnetron can be kept inside the oven and used to prevent the door from fogging even when used as a microwave oven. When the oven is in use, the fan motor is turned off to maintain the internal temperature.
オーブン使用後にファンモータを回すためには簡単な切
換スイッチだけで十分である。A simple changeover switch is sufficient to turn on the fan motor after using the oven.
