Description

【0001】
【発明の属する技術分野】
本発明は、加熱室に収納された食品を加熱室の上部に設けた上ヒータと、下部に設けた下ヒータと、後部に設けた熱風循環装置により加熱する加熱調理器に関するものである。
【0002】
【従来の技術】
従来の加熱調理器において、特開平11−166738号公報で開示されているように、食品を戴置する角形の上部受け皿と、下部受け皿を上下2段に収容配置することが可能な構成とされた加熱室と、この加熱室後面にあって前記上部受け皿の下部に位置するように設けられた吹出し口と、前記加熱室後面にあって前記下部受け皿の下部に位置するように設けられた吸込み口と、前記加熱室の後部にあって加熱室内の空気を前記吸込み口から吸込み前記吹出し口から加熱室内に吹出すことにより空気を循環させるファンとこのファンを回転駆動するモータと吹出す空気を熱する熱風ヒータとを備えた熱風循環装置と、加熱室上部の上ヒータと、加熱室底部に設けた下ヒータで構成され、食品の2段調理を行なうものがあった。
【0003】
【発明が解決しようとする課題】
上記従来の技術にあってはオーブン調理を行なうと加熱室の後部側の上部受け皿に戴置された食品は、吹出し口から吹出された直後の高温の熱風および加熱室上部に設けられた上ヒータの輻射熱で加熱されるが、加熱室の前部側の上受け皿に戴置された食品は、吹出し口から吹出された熱風が加熱室の前面に来るまでに熱を奪われ温度が低くなった熱風で加熱されることになる。
【0004】
すなわち、加熱室の後部側の上部受け皿に戴置された食品と、加熱室の前部側の上部受け皿に戴置された食品とは異なる温度で加熱されることになり、それらの食品で焼きむらが生じてしまうといった問題があった。
【0005】
【課題を解決するための手段】
上記の課題を解決するために本発明は、食品を戴置する上受皿と下受皿を上下2段に収容配置することが可能な加熱室と、この加熱室の後部にあって前記上受皿の下部に位置するように設けられた吹出し口と、加熱室の後部にあって前記下受皿の下部に位置するように設けられた吸込み口と、加熱室の後部外側にあって加熱室内の空気を前記吸込み口から吸込み、前記吹出し口から加熱室内に吹出すことにより空気を循環させるファンとこのファンから送り出された空気を熱する熱風ヒータとを設けた熱風循環装置と、加熱室の上部に設けた上ヒータと、加熱室の底部に設けた下ヒータとで構成される加熱調理器において、上ヒータを加熱室の奥行き方向の中心位置から手前の前方部に設けた上前ヒータと、前記中心位置から奥の後方部に設けた上後ヒータとに分けて配置するとともに、後方部に配置された上後ヒータの出力を可変可能にしたものである。
【0006】
【発明の実施の形態】
以下、本発明の一実施例について図面を用いて説明する。
【0007】
図1は本発明の一実施例を示す加熱調理器の側面図で、1は食品である。2は食品1を収納する加熱室である。3はドアで、加熱室2の前面に設けられ食品1などを加熱室2に出し入れするため開閉自在となっている。4はオーブン料理やグリル料理のとき食品1を戴置する受皿で、金属製の角形となっている。料理によっては上下2段で使用することもあり、上側に使用するものが上受皿4a、下側に使用するものが下受皿4bである。
【0008】
5aは上受皿棚で、加熱室2の左右両側壁に加熱室2の内側に突出し、上受皿4aを支持するものである。5bは下受皿棚で、上受皿棚5aと同形状で加熱室2の左右側壁の内側に突出し下受皿4bを支持するものである。
【0009】
6は熱風循環装置で、加熱室2の後部外側に設けられ、熱風を加熱室2に送り込んだり、加熱室2から吸込んだりして食品1を加熱するものである。この熱風循環装置6は外装となるケーシング6aと、このケーシング6a内の上部に設けられた熱風ヒータ6bと、下部に設けられたファン6cと、このファン6cを回転させる熱風モータ(図示せず)と、加熱室2へ吹出す熱風と加熱室2から戻る熱風の風路を仕切るガイド6dとで構成されている。
【0010】
7は加熱室2の後部壁面の下受皿4bの下方に設けられ、千鳥穴からなる吸込み口である。8は吹出し口で、加熱室2の後部壁面の上受皿4aと下受皿4bの中間位置に設けられ、吸込み口7と同じく千鳥穴で構成されている。
【0011】
従って、熱風循環装置6からの熱風は、吹出し口8から加熱室2に送り込まれ、加熱室2を循環して吸込み口7から再び熱風循環装置6に戻る。9は下ヒータで、加熱室2の底部外側に設けられている。
【0012】
10は加熱室2の上部外側に設けられている上ヒータである。この上ヒータ10は図2の加熱調理器の上部の平面図で示すように、加熱室2の奥行き方向の中心位置Aから前方部に設けた上前ヒータ10aと、前記中心位置Aから後方部に設けた上後ヒータ10bが夫々別個に設けられている。
【0013】
11は制御部で、下ヒータ9や上ヒータ10などの動作を制御するものである。12は機械室で、高周波を発振するマグネトロン12aやこのマグネトロン12aを冷却する冷却ファン12bなどが配置されている。13は操作パネルで、機能選択ボタン(図示せず)や温度設定ボタン(図示せず)、表示部(図示せず)などが設けられている。
【0014】
図3は各ヒータの回路図で、R1、R2は制御部11の指示でON−OFFを行なうリレーである。リレーR1は上前ヒータ10a、リレーR2は熱風ヒータ6bと下ヒータ9の動作をそれぞれ制御する。TRはトライアックで、制御部11の指示でON−OFF制御することにより上後ヒータ10bの出力を可変する。
【0015】
次に、上記にて構成された本発明の作用について説明する。
【0016】
クッキーを焼くオーブン料理の場合、上受皿4aと下受皿4bに下準備したクッキーを戴置し、ドア3を開け、上受皿4aは加熱室2に設けた上受皿棚5aに固定し、下受皿4bも同じように下受皿棚5bに固定し、ドア3を閉め加熱スタートすると各ヒータに通電される。
【0017】
各ヒータの動作を図3のヒータの回路図により説明をする。加熱スタートすると制御部11の指示でリレーR2がONとなり下ヒータ9と熱風ヒータ6bが動作する。予め設定された時間になるとリレーR2はOFFとなり、同時に制御部11の指示によりリレーR1とトライアックTRがONとなり、上前ヒータ10aと上後ヒータ10bが動作する。
【0018】
以下、図4の各ヒータの動作図に示すように、各ヒータは予め設定した時間、出力で動作する。本実施例では上前ヒータ10aの出力は約700W、上後ヒータ10bの出力は約500W、そして熱風ヒータ6bと下ヒータ9は同時動作し合計出力は1200Wとした。
【0019】
加熱室2を予め設定された温度、例えば約160℃まで上げ、設定された時間、例えば25分の間加熱室2内の温度が160℃になるよう制御部11で下ヒータ9、上ヒータ10そして熱風ヒータ6bをON−OFF制御する。
【0020】
また、加熱スタートと同時に熱風モータ(図示せず)が回転しファン6cが回転する。回転したファン6cで送風された空気は熱風ヒータ6bで加熱され、熱風となり吹出し口8から加熱室2内に熱風を送り込まれる。送り込まれた熱風は上受皿4aと下受皿4bの間を通ってドア3方向へ流れる。この時熱風は上受皿4aの底部を加熱して食品1の底部を加熱し、下受皿4bの食品1を上部から加熱する。
【0021】
そして、熱風はドア3に当たりここで下向きに方向を変え、下受皿4bの底部側に沿って吸込み口7方向に流れる。このとき熱風は下受皿4bの底部を加熱することにより下受皿4bの食品1を底部から加熱する。
【0022】
吸込み口7から熱風循環装置6内に入った熱風はガイド6dに沿ってファン6cに流れ、ここから再び熱風ヒータ6bへ送風され加熱される。
【0023】
このように熱風は加熱室2内を循環することにより食品1を加熱する。
【0024】
しかし、下受皿4bの底部を流れる熱風は温度が下がるため、下ヒータ9により熱風を温めるとともに下受皿4b底部を直接加熱し、加熱不足にならないようにしている。
【0025】
一方、上受皿4aの上部は熱風が流れない。これは加熱室2の後部側には空気が流れるための孔などが無いため、閉路となり風路が構成されず、熱風は入り込めない。従って、上受皿4aの上面は上ヒータ10の熱源により加熱される。
【0026】
しかし、吹出し口8から吹出された直後の熱風は温度が高いが、前方に流れていくにつれて食品1などに熱が奪われ次第に温度が下がり、加熱室2の前方と後方とでは温度差が生じてしまう。そこで、上後ヒータ10bの出力を可変可能とし、出力を減らすことにより加熱室2の前方と後方の温度差を極力減らすよう調整し、食品1を均一に加熱することができるようにする。
【0027】
具体的には制御部11でトライアックTRを制御することにより上後ヒータ10bの出力を、例えば上前ヒータ10aの出力が700Wとすると500Wに下げる。
【0028】
このようにして加熱室2の温度を制御して定められた温度を保持し、設定された加熱時間に達すると加熱は終了する。
【0029】
上記の説明は、設定された加熱室2内の温度で食品1を加熱するオーブン料理の場合であったが、焼き魚などの食品1を加熱するグリル調理の場合、上ヒータ10のふく射熱のみで加熱するため、図5で示す各ヒータの動作図で示すように上後ヒータ10bの出力を上前ヒータ10aと同じ700Wの高出力にすることで、上受皿4aの全面に均一に熱を与えることができ、食品1を均一に加熱することができる。
【0030】
尚、グリル料理の場合は、受皿4を2段に分けて使用できず、1段のみとなる。
【0031】
このように、オーブン料理、あるいはグリル料理により上後ヒータ10bの出力調整をおこなうことにより、上受皿4aの食品1を均一に加熱することができる。
【0032】
【発明の効果】
以上説明したように、本発明によれば、食品を戴置する上受皿と下受皿を上下2段に収容配置することが可能な加熱室と、この加熱室の後部にあって前記上受皿の下部に位置するように設けられた吹出し口と、加熱室の後部にあって前記下受皿の下部に位置するように設けられた吸込み口と、加熱室の後部外側にあって加熱室内の空気を前記吸込み口から吸込み、前記吹出し口から加熱室内に吹出すことにより空気を循環させるファンとこのファンから送り出された空気を熱する熱風ヒータとを設けた熱風循環装置と、加熱室の上部に設けた上ヒータと、加熱室の底部に設けた下ヒータとで構成される加熱調理器において、上ヒータを加熱室の奥行き方向の中心位置から手前の前方部に設けた上前ヒータと、前記中心位置から奥の後方部に設けた上後ヒータとに分けて配置するとともに、後方部に配置された上後ヒータの出力を可変可能にしたことにより、加熱室内の前方部と後方部の庫内温度が均一になり、オーブン料理やグリル料理の食品を均一に焼き上げることができるなどの効果がある。

[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0007]
FIG. 1 is a side view of a cooking device showing one embodiment of the present invention, and 1 is a food. Reference numeral 2 denotes a heating chamber for storing the food 1. Reference numeral 3 denotes a door, which is provided on the front surface of the heating chamber 2 and is openable and closable so that the food 1 and the like can be taken in and out of the heating chamber 2. Reference numeral 4 denotes a saucer on which the food 1 is placed in the case of an oven dish or a grill dish, and has a metal square shape. Some dishes are used in upper and lower stages, and the upper one is the upper tray 4a, and the lower one is the lower tray 4b.
[0008]
Reference numeral 5a denotes an upper tray shelf, which protrudes into the inside of the heating chamber 2 on both left and right side walls of the heating chamber 2 and supports the upper tray 4a. Reference numeral 5b denotes a lower tray shelf, which has the same shape as the upper tray shelf 5a and projects inside the left and right side walls of the heating chamber 2 to support the lower tray 4b.
[0009]
Reference numeral 6 denotes a hot air circulating device, which is provided outside the rear part of the heating chamber 2 and sends the hot air to the heating chamber 2 or sucks the hot air from the heating chamber 2 to heat the food 1. The hot air circulation device 6 includes a casing 6a serving as an exterior, a hot air heater 6b provided in an upper portion of the casing 6a, a fan 6c provided in a lower portion, and a hot air motor (not shown) for rotating the fan 6c. And a guide 6d for partitioning an air path of hot air blown out to the heating chamber 2 and hot air returning from the heating chamber 2.
[0010]
Reference numeral 7 denotes a suction port provided below the lower tray 4b of the rear wall of the heating chamber 2 and formed in a staggered hole. Reference numeral 8 denotes an outlet, which is provided at an intermediate position between the upper receiving tray 4a and the lower receiving tray 4b of the rear wall surface of the heating chamber 2, and has a staggered hole like the inlet 7.
[0011]
Therefore, the hot air from the hot air circulation device 6 is sent into the heating chamber 2 from the outlet 8, circulates through the heating chamber 2, and returns to the hot air circulation device 6 again from the suction port 7. A lower heater 9 is provided outside the bottom of the heating chamber 2.
[0012]
Reference numeral 10 denotes an upper heater provided outside the upper portion of the heating chamber 2. As shown in a plan view of the upper portion of the heating cooker in FIG. 2, the upper heater 10 is provided with an upper front heater 10a provided at a front portion from a center position A in the depth direction of the heating chamber 2, and a rear portion provided at the rear portion from the center position A. And the rear heaters 10b are separately provided.
[0013]

Reference numeral 12 denotes a machine room in which a magnetron 12a for oscillating high frequency, a cooling fan 12b for cooling the magnetron 12a, and the like are arranged. An operation panel 13 is provided with a function selection button (not shown), a temperature setting button (not shown), a display unit (not shown), and the like.
[0014]
FIG. 3 is a circuit diagram of each heater. R1 and R2 are relays that perform ON / OFF according to an instruction from the control unit 11. The relay R1 controls the operation of the upper front heater 10a, and the relay R2 controls the operation of the hot air heater 6b and the lower heater 9, respectively. TR is a triac, which varies the output of the upper rear heater 10b by performing ON-OFF control according to an instruction from the control unit 11.
[0015]
Next, the operation of the present invention configured as described above will be described.
[0016]
In the case of oven cooking for baking cookies, the prepared cookie is placed on the upper tray 4a and the lower tray 4b, the door 3 is opened, and the upper tray 4a is fixed to the upper tray shelf 5a provided in the heating chamber 2, and the lower tray 4a is fixed. Similarly, 4b is fixed to the lower tray shelf 5b, and when the door 3 is closed and heating is started, each heater is energized.
[0017]
The operation of each heater will be described with reference to the heater circuit diagram of FIG. When heating is started, the relay R2 is turned on by an instruction from the control unit 11, and the lower heater 9 and the hot air heater 6b operate. At a preset time, the relay R2 is turned off, and at the same time, the relay R1 and the triac TR are turned on by an instruction from the control unit 11, and the upper front heater 10a and the upper rear heater 10b operate.
[0018]
Hereinafter, as shown in the operation diagram of each heater in FIG. 4, each heater operates with an output for a preset time. In this embodiment, the output of the upper front heater 10a is about 700 W, the output of the upper rear heater 10b is about 500 W, and the hot air heater 6b and the lower heater 9 are operated simultaneously, and the total output is 1200 W.
[0019]
The temperature of the heating chamber 2 is raised to a preset temperature, for example, about 160 ° C., and the control unit 11 controls the lower heater 9 and the upper heater 10 so that the temperature in the heating chamber 2 becomes 160 ° C. for a set time, for example, 25 minutes. Then, the hot air heater 6b is ON-OFF controlled.
[0020]
At the same time as the start of heating, the hot air motor (not shown) rotates and the fan 6c rotates. The air blown by the rotated fan 6c is heated by the hot air heater 6b, becomes hot air, and is sent into the heating chamber 2 from the outlet 8. The sent hot air flows toward the door 3 through the space between the upper tray 4a and the lower tray 4b. At this time, the hot air heats the bottom of the upper tray 4a to heat the bottom of the food 1, and heats the food 1 in the lower tray 4b from above.
[0021]
Then, the hot air hits the door 3 and changes its direction here, and flows in the direction of the suction port 7 along the bottom side of the lower receiving tray 4b. At this time, the hot air heats the bottom of the lower tray 4b to heat the food 1 in the lower tray 4b from the bottom.
[0022]
The hot air that has entered the hot air circulating device 6 from the suction port 7 flows along the guide 6d to the fan 6c, where it is sent to the hot air heater 6b again to be heated.
[0023]
Thus, the hot air circulates through the heating chamber 2 to heat the food 1.
[0024]
However, since the temperature of the hot air flowing through the bottom of the lower tray 4b decreases, the hot air is heated by the lower heater 9 and the bottom of the lower tray 4b is directly heated to prevent insufficient heating.
[0025]
On the other hand, hot air does not flow over the upper tray 4a. This is because there is no hole or the like for the air to flow on the rear side of the heating chamber 2, so that it is closed and no air path is formed, so that hot air cannot enter. Therefore, the upper surface of the upper receiving tray 4a is heated by the heat source of the upper heater 10.
[0026]
However, although the temperature of the hot air immediately after being blown out from the outlet 8 is high, as the food flows forward, the heat is taken away by the food 1 or the like, and the temperature gradually decreases, and a temperature difference occurs between the front and rear of the heating chamber 2. Would. Therefore, the output of the upper rear heater 10b is made variable, and the output is reduced so that the temperature difference between the front and rear of the heating chamber 2 is adjusted to be as small as possible, so that the food 1 can be uniformly heated.
[0027]
Specifically, the controller 11 controls the triac TR to reduce the output of the upper rear heater 10b to 500W, for example, when the output of the upper front heater 10a is 700W.
[0028]
In this way, the temperature of the heating chamber 2 is controlled to maintain the predetermined temperature, and when the set heating time is reached, the heating ends.
[0029]
In the above description, the case of the oven cooking in which the food 1 is heated at the set temperature in the heating chamber 2 is used. However, in the case of grill cooking in which the food 1 such as grilled fish is heated, the heating is performed only by the radiant heat of the upper heater 10. Therefore, as shown in the operation diagram of each heater shown in FIG. 5, the output of the upper rear heater 10b is set to the same high output of 700 W as that of the upper front heater 10a, thereby uniformly applying heat to the entire surface of the upper tray 4a. And the food 1 can be uniformly heated.
[0030]
In the case of grilled dishes, the saucer 4 cannot be used in two stages, and only one stage is used.
[0031]
As described above, by adjusting the output of the upper rear heater 10b by the oven cooking or the grill cooking, the food 1 in the upper receiving tray 4a can be uniformly heated.
[0032]
