状態から食品に対する実際の加熱動作を設定時間t2行な
うものがある。As the oven cooking, for example, as shown in FIG. 4, first, a preheating operation for a set time t 1 is performed to raise the temperature of the heating chamber (also referred to as the inside temperature) to a set value T 0 , and the state is applied to food. Some of them perform the actual heating operation for a set time t 2 .
ただし、このように予熱動作を予め行なう調理では、

One end of a waveguide 3 communicates with the irradiation port 2. A magnetron 4 is attached to the outer circumference of the other end of the waveguide 3, and the antenna 4 a of the magnetron 4 is introduced into the waveguide 3. In the heating chamber 1, an electric heater 5 for oven cooking is arranged near the ceiling surface. A heating chamber temperature sensor 6 is attached to the side wall of the heating chamber 1.

It is connected to the commercial AC power source 8 via a. The heater 5 is connected to the power source 8 via the relay contact 14a. The control unit 10 is connected to the power source 8 via the transformer 9.
制御部10は、電子レンジ全般にわたる制御を行なうも

接続されている。The control unit 10 controls the entire microwave oven, is composed of a microcomputer and its peripheral circuits, etc., and is externally connected with an operation unit 11, a display unit 12, and relays 13 and 14.
つぎに、上記のような構成において第２図および第３
図を参照しながら作用を説明する。Next, FIG. 2 and FIG.
The operation will be described with reference to the drawings.
加熱室１内に食品を収め、操作部11で食品の種類や調

始される。The food is stored in the heating chamber 1, the type of food and the cooking content (oven cooking) are set by the operation unit 11, and the cooking start operation is performed. Then, the control unit 10 energizes the relay 14. When the relay 14 is energized, the contact 14a is turned on to energize the heater 5, and the oven cooking is started by the heat generated by the heater 5.
この調理時、制御部20は、食品の種類や調理内容に対
応して予め設定された設定温度データToをメモリから読

比較する。そして、比較結果に応じてリレー14の付勢を
オン，オフする。つまり、検知温度Taが設定温度Toに対

フする。During this cooking, the control unit 20 reads the preset temperature data To corresponding to the type of food and the content of cooking from the memory, fetches the detection temperature (temperature of the heating chamber) Ta of the temperature sensor 6, and detects it. The temperature Ta is compared with the set temperature To. Then, the bias of the relay 14 is turned on and off according to the comparison result. That is, the energization of the heater 5 is turned on and off so that the detected temperature Ta becomes substantially constant with respect to the set temperature To.
こうして、調理開始時はヒータ５が連続的に動作し、
検知温度Taがどんどん上昇する。このとき、制御部20
は、検知温度Taが設定温度Toに達するまでの間、一定時
間Δｔ（たとえば30秒）ごとに加熱室内温度Taの変化Δ
Ｔを検出し、Δｔ時間における平均加熱室内温度を算出
する。Thus, when cooking is started, the heater 5 operates continuously,
The detection temperature Ta rises steadily. At this time, the control unit 20
Is the change Δ in the heating chamber temperature Ta at regular intervals Δt (for example, 30 seconds) until the detected temperature Ta reaches the set temperature To.
T is detected, and the average heating chamber temperature at Δt time is calculated.
平均加熱室内温度＝Tx＋ΔT/2 さらに、制御部20は、算出した平均加熱室内温度にΔ

するまでの加熱エネルギP1を算出する。なお、t4は検知
温度Taが設定温度Toに達するまでにかかる時間である。Average heating chamber temperature = Tx + ΔT / 2 Further, the control unit 20 adds Δ to the calculated average heating chamber temperature.
The heating energy at Δt time is calculated by multiplying by t time. Then, the heating energy P 1 until the detected temperature Ta reaches the set temperature To is calculated. Note that t 4 is the time required for the detected temperature Ta to reach the set temperature To.

の加熱に必要なエネルギ）を求める。そして、制御部20
は、残り加熱エネルギP2を設定温度Toで割ることによ
り、残り加熱時間t5を算出する。 When the detected temperature Ta reaches the set temperature To, the control unit 20 reads out the total heating energy data P that is predetermined corresponding to the type of food and the cooking content from the memory, and calculates the total heating energy P and the above. Find the difference P 2 from the heating energy P 1 (energy required for the remaining heating). And the control unit 20
Calculates the remaining heating time t 5 by dividing the remaining heating energy P 2 by the set temperature To.
t5＝P2/To ＝（Ｐ−P1）/To こうして、検知温度Taが設定温度Toに達してからt5時
間が経過すると、制御部20はリレー14を消勢し、ヒータ
５への通電を完全に停止する。つまり、調理の終了とな
る。t 5 = P 2 / To = (P−P 1 ) / To Thus, when t 5 time elapses after the detected temperature Ta reaches the set temperature To, the control unit 20 deenergizes the relay 14 and sends it to the heater 5. Stop energizing completely. That is, cooking is completed.

調理時間の短縮が図れることは勿論である。In this way, the heating end timing is set so as to satisfy the predetermined total heating energy P. Therefore, even if the initial value of the heating room temperature is different due to the residual heat of the previous cooking or the room temperature, the influence thereof will be affected. It is possible to always perform stable and good-quality cooking without receiving anything. Since the preheating operation is omitted, the cooking time as a whole can be shortened.

For those that are maintained at the temperature, the heating energy from the start of cooking until the heating chamber reaches the set temperature is calculated, and the remaining heating time is set according to the difference between the total heating energy and the calculated heating energy. Since it is configured so that the preheating operation can be omitted and the heating time can be shortened, stable and good cooking can always be achieved without being affected by the difference in the initial value of the heating room temperature. It is possible to provide a cooking device that enables it.
