【発明の詳細な説明】
本発明は、加熱調理開始前において加熱室内の
条件をもとにもどすようにした調理器に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking appliance that restores the conditions in a heating chamber to their original state before starting cooking.
従来、湿度センサー、ガスセンサー等を用いて
加熱調理を制御する調理器においては通常加熱調
理開始に先立つて加熱室内の条件をもとにもどす
いわゆるクリーニング時間を設定する為の手段を
設けている。 Conventionally, cooking appliances that control cooking using humidity sensors, gas sensors, etc. are usually provided with means for setting a so-called cleaning time to restore the conditions in the heating chamber to their original state before starting cooking.
その理由は、センサーにヒータが付随しており
該ヒータに通電されてからセンサーの低抗値が安
定する迄にかなりの時間が必要であること、及び
調理開始時において前回行なつた加熱調理によつ
て加熱室内に残留した不要なガスや高温の空気等
を加熱室外に放出する必要があることである。 The reason for this is that the heater is attached to the sensor, and it takes a considerable amount of time after the heater is energized until the low resistance value of the sensor stabilizes, and also because the heating process that was previously performed when starting cooking Therefore, it is necessary to discharge unnecessary gas, high temperature air, etc. remaining in the heating chamber to the outside of the heating chamber.
しかし、従来汎用されている調理器においては
第３図ｂに示すようにクリーニング時間T1が毎
回同じであることから次のような欠点を有してい
た。即ち、
特にヒータを有する調理器にて魚を焼く等の
グリル調理を行なつた後においては、加熱室内
にガスが充満するのみならずオーブンも極めて
高い温度となつており、
また連続して何度も調理を行なうと、加熱室
内の温度が徐々に上昇する。 However, conventionally used cooking appliances have the following drawbacks because the cleaning time T1 is the same each time as shown in FIG. 3b. In other words, especially after grilling such as grilling fish using a cooker equipped with a heater, not only is the heating chamber filled with gas, but the oven is also at an extremely high temperature, and the temperature of the oven is extremely high. During cooking, the temperature inside the heating chamber gradually increases.
これらの状態において、毎回同じクリーニング
時間しか設定できないので、ガスの量が多すぎた
り、温度が高すぎたりするとクリーニング時間経
過時において通常の使用条件における初期条件に
もどらないことにより基準設定レベルが変動し、
従つて加熱調理制御にあたつて、最適加熱調理状
態に達する前に加熱調理を停止することとなつて
いた。 Under these conditions, only the same cleaning time can be set each time, so if the amount of gas is too large or the temperature is too high, the reference setting level will fluctuate as the cleaning time will not return to the initial conditions under normal usage conditions. death,
Therefore, in heating cooking control, heating cooking must be stopped before the optimum heating state is reached.

成る。 The cleaning time setting means 4, which is the most essential aspect of the present invention, includes a resistor 40 between the voltage terminals 8 and 9.
41 series connection circuit, resistor 44 and capacitor 45
A series connection circuit between the relay coil 48 and the collector emitter terminal of the transistor 49 is connected in parallel, and a comparison input terminal is connected to the connection point 46 between the resistor 44 and the capacitor 45. The output terminal of the transistor 47 is connected to the base terminal of the transistor 49, the input terminal is connected to the connection point 43 between the resistors 40 and 41, and a thermistor 42 is connected in parallel with the resistor 40.

アモータ２への通電を制御するようにしている。 The relay contacts 10 operated by the relay coil 38 are connected in series to the heating means 1 and the blower motor 2, respectively, and the relay contacts 11 operated by the relay coil 48 are connected in series to the heating means 1. The heating means 1 and the blower motor 2 are controlled to be energized by the heating means 1 and the blower motor 2.
以上の構成になる調理器の作用は次のとおりで
ある。 The operation of the cooker having the above structure is as follows.
図示しない加熱室の扉を開いて被加熱物を調理
室内に入れ、次に該扉を閉じて調理スイツチ５を
投入するとトランス６の一次側巻線に通電される
とともに常閉型のリレー接点１０を介してブロア
モータ２に通電される。 When the door of the heating chamber (not shown) is opened and the object to be heated is placed in the cooking chamber, the door is then closed and the cooking switch 5 is turned on, the primary winding of the transformer 6 is energized and the normally closed relay contact 10 is turned on. The blower motor 2 is energized via.
この状態においてはリレー接点１１が遮断状態
で加熱手段１には通電されないので加熱室内の残
留空気を放出するクリーニング動作を行なう。 In this state, the relay contact 11 is cut off and the heating means 1 is not energized, so a cleaning operation is performed to release the residual air in the heating chamber.
また、トランス６の一次側巻線に通電されると
二次側巻線に所定電圧が誘起されるので抵抗４４
を介してコンデンサ４５が徐々に充電され、接続
点４６の電圧は第２図に示すように徐々に上昇す
る。 Furthermore, when the primary winding of the transformer 6 is energized, a predetermined voltage is induced in the secondary winding, so the resistor 44
The capacitor 45 is gradually charged through the capacitor 45, and the voltage at the connection point 46 gradually increases as shown in FIG.
該接続点４６の電圧が、抵抗４０，４１及びサ
ーミスタ４２により決定される接続点４３の電圧
以上になるとトランジスタ４９が導通されるので
リレーコイル４８に通電され、従つてリレー接点
１１が導通され加熱手段１に通電されて被加熱物
の加熱調理を行なう。 When the voltage at the connection point 46 exceeds the voltage at the connection point 43 determined by the resistors 40, 41 and thermistor 42, the transistor 49 becomes conductive, so the relay coil 48 is energized, and the relay contact 11 is therefore conductive and heated. The means 1 is energized to heat and cook the object to be heated.
加熱調理を開始した後は被加熱物から発生する
水分、ガス等の濃度に依存してセンサー３２の抵
抗値が変化する為接続点３３の電圧も変化する。 After heating and cooking is started, the resistance value of the sensor 32 changes depending on the concentration of moisture, gas, etc. generated from the object to be heated, so the voltage at the connection point 33 also changes.
そして該接続点３３の電圧が可変抵抗３５の可
変出力端子３６の電圧と等しくなるとトランジス
タ３９を導通させることによりリレーコイル３８
に通電し、リレー接点１０を遮断して加熱手段１
及びブロアモータ２への通電を遮断し、以て加熱
調理を停止させる。 When the voltage at the connection point 33 becomes equal to the voltage at the variable output terminal 36 of the variable resistor 35, the relay coil 38 is turned on by making the transistor 39 conductive.
is energized, the relay contact 10 is cut off, and the heating means 1
Then, the power supply to the blower motor 2 is cut off, thereby stopping the heating cooking.
尚、このときトランス６の一次側巻線への通電
も遮断するようにしている。（図示せず）
また、一度加熱調理をした後直ちに加熱調理を
行なう場合においては、加熱室内の温度が高い為
サーミスタ４２の抵抗値が低くなつており、従つ
て接続点４３の電圧が高くなつているので接続点
４６の電圧が接続点４３の電圧と等しくなる迄長
時間かかる。 At this time, the power supply to the primary winding of the transformer 6 is also cut off. (Not shown) In addition, when cooking is performed immediately after heating once, the resistance value of the thermistor 42 becomes low because the temperature inside the heating chamber is high, and therefore the voltage at the connection point 43 becomes high. Therefore, it takes a long time until the voltage at the connection point 46 becomes equal to the voltage at the connection point 43.
即ち、加熱室内の温度が高い時にはより長い時
間クリーニング動作を行なうことができ、加熱調
理が不完全な状態で加熱調理を停止するという誤
動作を皆無にすることができる。 That is, when the temperature inside the heating chamber is high, the cleaning operation can be carried out for a longer time, and it is possible to completely eliminate the malfunction of stopping heating cooking when heating is incomplete.
以上には加熱室の温度を検出する為サーミスタ
を用いた実施例について述べたが、正特性熱依存
性抵抗器等温度によつて抵抗値が変化する素子で
あれば使用できることは勿論である。 The embodiment described above uses a thermistor to detect the temperature of the heating chamber, but it goes without saying that any element whose resistance value changes depending on the temperature, such as a positive characteristic heat-dependent resistor, can be used.
以上のようになる本発明の調理器は次の効果を
奏する。 The cooking device of the present invention as described above has the following effects.
クリーニング時間を加熱室内の温度に依存して
変化させるようにしたので常に適正なクリーニン
