Description

本発明は、送風ファンとヒータとによって熱風を発生させる対流加熱を用いて被加熱物を調理する加熱装置に関するものである。   The present invention relates to a heating apparatus that cooks an object to be heated using convection heating in which hot air is generated by a blower fan and a heater.

従来、この種の加熱装置は一般的に、被加熱物が調理される加熱室の背面後方にファン装置を備え、加熱室内の空気を加熱室内の後壁に設けられた吸込口から熱風循環装置（熱源室）のケーシング内に吸い込み、ヒータで加熱された熱風を加熱室内の後壁に設けられた吹出口から吹き出す構造を有しており、この熱風の循環を利用した対流加熱によって調理を行うものである。   Conventionally, this type of heating device is generally provided with a fan device behind the heating chamber in which the object to be heated is cooked, and the hot air circulation device supplies air in the heating chamber from a suction port provided on the rear wall of the heating chamber. (Heat source chamber) has a structure in which the hot air heated by the heater is blown out from the air outlet provided on the rear wall of the heating chamber, and cooking is performed by convection heating using the circulation of the hot air Is.

このような加熱装置においては、ケーシング内に設けられた風向板を用いて熱風を加熱室内に均一に供給し、庫内温度分布の均一化を図ることにより、焼き上げ性能を向上させている（例えば、特許文献１参照）。さらにムラなく加熱調理するために、熱風の風向を変えるための部材を吹出口の近傍に設け、熱風が加熱室内で均一に広がるようにしているものがある（例えば、特許文献２参照）。   In such a heating device, hot air is uniformly supplied into the heating chamber using a wind direction plate provided in the casing, and the temperature distribution in the cabinet is made uniform to improve the baking performance (for example, , See Patent Document 1). In addition, in order to cook evenly, there is a member that changes the direction of the hot air in the vicinity of the air outlet so that the hot air spreads uniformly in the heating chamber (see, for example, Patent Document 2).

図１０は、特許文献１に記載された従来の加熱装置を示すものである。図１０に示されるように、加熱装置には、加熱室１の後壁の外面に設けられたケーシング２内に、遠心ファンよりなる送風ファン３と略環状のヒータ４とが設けられる。加熱室１の後壁の中央には、多数のパンチング孔よりなる吸込口５が形成され、吸込口５を挟む上下の位置に多数のパンチング孔よりなる吹出口６がそれぞれ帯状に形成される。   FIG. 10 shows a conventional heating apparatus described in Patent Document 1. In FIG. As shown in FIG. 10, the heating device is provided with a blower fan 3 made of a centrifugal fan and a substantially annular heater 4 in a casing 2 provided on the outer surface of the rear wall of the heating chamber 1. In the center of the rear wall of the heating chamber 1, a suction port 5 made up of a large number of punching holes is formed, and a blower outlet 6 made up of a number of punching holes is formed in a strip shape at positions above and below the suction port 5.

送風ファン３は、ケーシング２で形成されたファン室内に吸込口５に対向して設けられた遠心ファンであり、ケーシング２の外部に設けたモータ７により回転駆動される。ヒータ４は、送風ファン３の外周囲（吹出側）に設けられた略環状のシーズヒータである。送風ファン３の半径方向外側の吹出口６と対向するケーシング２の内側には、吹出口６の近傍まで延びる風向板８が設けられる。   The blower fan 3 is a centrifugal fan provided in the fan chamber formed of the casing 2 so as to face the suction port 5, and is rotationally driven by a motor 7 provided outside the casing 2. The heater 4 is a substantially annular sheathed heater provided on the outer periphery (outlet side) of the blower fan 3. A wind direction plate 8 extending to the vicinity of the air outlet 6 is provided inside the casing 2 facing the air outlet 6 on the radially outer side of the blower fan 3.

上記構造の加熱装置において、加熱室１内に被加熱物Ｓを載置し加熱調理を開始させると、モータ７により送風ファン３が回転し、加熱室１の空気が吸込口５からケーシング２内に吸い込まれ、送風ファン３の半径方向外方に送り出される。送り出された空気は、ヒータ４により加熱され、吹出口６から加熱室１に戻される。このようにして、加熱室１内とケーシング２内とを熱風が循環し、対流加熱が行われる。   In the heating apparatus having the above structure, when the object to be heated S is placed in the heating chamber 1 and heating cooking is started, the blower fan 3 is rotated by the motor 7, and the air in the heating chamber 1 passes through the suction port 5 into the casing 2. And is sent out radially outward of the blower fan 3. The sent-out air is heated by the heater 4 and returned to the heating chamber 1 from the air outlet 6. In this way, hot air circulates in the heating chamber 1 and the casing 2 to perform convection heating.

対流加熱が開始すると、熱風の一部が風向板８に遮られて、ファンの回転方向と反対側に戻ろうとするため、ファンの回転方向と逆方向に位置する吹出口６からの熱風量が増加し、その分、送風ファン３の回転方向に位置する吹出口６からの熱風量が減少する。このようにして、風向板８により、熱風が吹出口６から加熱室内に均一に供給されることができ、加熱ムラを抑制することができる。   When the convection heating is started, a part of the hot air is blocked by the wind direction plate 8 and tries to return to the opposite side of the fan rotation direction, so that the amount of hot air from the outlet 6 located in the direction opposite to the fan rotation direction is increased. The amount of hot air from the blower outlet 6 located in the rotation direction of the blower fan 3 is decreased. In this way, hot air can be uniformly supplied from the outlet 6 into the heating chamber by the wind direction plate 8, and uneven heating can be suppressed.

しかしながら、上記従来の構成において、送風ファン３からの空気流は、送風ファン３の半径方向、すなわち、ケーシング２内において加熱室１の後壁に沿って吹き出す。   However, in the above-described conventional configuration, the air flow from the blower fan 3 blows out in the radial direction of the blower fan 3, that is, along the rear wall of the heating chamber 1 in the casing 2.

それに加えて、送風ファン３からの空気流の風向は、送風ファン３の回転に応じてファンの半径方向から回転方向に傾いて、いわば渦巻き状外向きとなり、ファンの風量と回転数の関係によってはほぼ送風ファン３の接線方向に熱風が吹き出す場合もある。このため、熱風が、ファンの回転方向側に位置する吹出口６に片寄って吹き出す。   In addition, the airflow direction of the airflow from the blower fan 3 is inclined in the direction of rotation from the radial direction of the fan according to the rotation of the blower fan 3, so that it becomes a spiral outward direction. In some cases, hot air blows out almost in the tangential direction of the blower fan 3. For this reason, a hot air blows off and blows off to the blower outlet 6 located in the rotation direction side of a fan.

ここで、ケーシング２の内側に風向板８を設けて、ファンの回転方向と反対方向に位置する吹出口６からの熱風量が増加するようにしても、吹出口６から吹き出す熱風の風向は、ファンの外周の接線方向に近い風向となる。   Here, even if the wind direction plate 8 is provided inside the casing 2 and the amount of hot air from the air outlet 6 located in the direction opposite to the rotation direction of the fan is increased, the direction of the hot air blown from the air outlet 6 is The wind direction is close to the tangential direction of the outer periphery of the fan.

このため、加熱室１後壁の下方にある吹出口６からの熱風は加熱室１底面に沿って、加熱室１後壁の上方にある吹出口６からの熱風は加熱室１上面に沿って、加熱室１後壁の側方端部にある吹出口６からの熱風は側壁面に沿ってそれぞれ流れるので、熱風が加熱室１の壁面ばかりを加熱することになる。   For this reason, the hot air from the blower outlet 6 below the heating chamber 1 rear wall is along the bottom surface of the heating chamber 1, and the hot air from the blower outlet 6 above the heating chamber 1 rear wall is along the upper surface of the heating chamber 1. Since the hot air from the outlet 6 at the side end of the rear wall of the heating chamber 1 flows along the side wall surface, the hot air heats only the wall surface of the heating chamber 1.

従って、被加熱物である食品よりも加熱室の壁面の方が高温になって放熱ロスが増加し、効率的に食品を加熱することができないという課題を有していた。   Therefore, the wall surface of the heating chamber becomes higher in temperature than the food that is the object to be heated, and the heat dissipation loss increases, so that the food cannot be efficiently heated.

また、送風ファン３の外周の略接線方向であってファンの回転軸に垂直方向に吹き出した空気の流れは、熱源室のケーシング２の奥行き寸法を小さくすると、その風向が加熱室１の中央方向に向きにくくなる。   Further, the flow of the air blown out in the direction substantially tangential to the outer periphery of the blower fan 3 and perpendicular to the rotation axis of the fan is reduced in the depth dimension of the casing 2 of the heat source chamber, and the wind direction is the central direction of the heating chamber 1. It becomes difficult to face.

吹出口６からの熱風は、加熱室１内の後壁に沿うような向きに吹き出すと、加熱室１の上下左右の壁面に衝突してしまい、さらに壁面ばかりを加熱する。このように、食品の加熱効率がさらに悪化するという課題を有していた。   When hot air from the outlet 6 blows out in a direction along the rear wall in the heating chamber 1, it collides with the upper, lower, left and right wall surfaces of the heating chamber 1 and further heats only the wall surfaces. Thus, there was a problem that the heating efficiency of food further deteriorated.

本発明は上記従来の課題を解決するもので、吹出口からの熱風の一部を加熱室内の中央方向に集中させることにより、加熱室壁面からの放熱ロスを低減させ、被加熱物を効率的に加熱調理することができる加熱装置を提供することを目的とする。   The present invention solves the above-described conventional problems, and by concentrating a part of the hot air from the outlet in the central direction of the heating chamber, the heat dissipation loss from the wall surface of the heating chamber is reduced, and the object to be heated is efficiently An object of the present invention is to provide a heating apparatus capable of cooking by heating.

上記従来の課題を解決するために、本発明の加熱装置は、内部に被加熱物を載置する加熱室と、吸込口と少なくとも２つの吹出口とを有し加熱室の壁面を構成する隔壁と、加熱室の外側に設けられ隔壁との間に空間を形成する筐体を有し空間内に設けられた送風ファンと加熱手段とにより吹出口から加熱室に熱風を供給する熱源室とを備えた加熱装置であって、熱源室内には、少なくとも２つの吹出口の各々と送風ファンとの間に回転方向の風を受け加熱室中央へ吹出す略Ｌ字形で点対称の位置に２つの仕切板を設けたものである。   In order to solve the above-described conventional problems, a heating device according to the present invention includes a heating chamber in which an object to be heated is placed, a suction port, and at least two air outlets, which form a wall of the heating chamber. And a heat source chamber that has a housing that is provided outside the heating chamber and forms a space between the partition walls, and that supplies hot air from the outlet to the heating chamber by a blower fan and heating means provided in the space. In the heat source chamber, in the heat source chamber, there are two substantially L-shaped point-symmetrical positions that receive wind in the rotational direction between each of the at least two outlets and the blower fan and blow out to the center of the heating chamber. A partition plate is provided.

上記構成により、熱源室内において、送風ファンと加熱手段とにより生成された熱風の一部は、略Ｌ字形で送風ファンを中心に点対称の位置に設けた仕切板に遮られ加熱室中央へ吹き出す。   With the above configuration, a part of the hot air generated by the blower fan and the heating means in the heat source chamber is blocked by a partition plate provided at a point-symmetrical position around the blower fan in a substantially L shape and blown out to the center of the heating chamber. .

残りの熱風は熱源室の隅付近まで達し、そこで風向を変えて他の吹出口に向かう。加熱室内において、吹出口から加熱室に供給される熱風は加熱室の中央方向、すなわち、被加熱物の方向と加熱室の壁面の両方に向かうようになる。   The remaining hot air reaches the vicinity of the corner of the heat source room, where it changes the direction of the wind and heads to another outlet. In the heating chamber, the hot air supplied from the outlet to the heating chamber is directed toward the center of the heating chamber, that is, both the direction of the object to be heated and the wall surface of the heating chamber.

本発明にかかる加熱装置によれば、略Ｌ字形で点対称の仕切板を設けた位置の吹出口からの熱風で加熱室内の中央方向に集中させることができる。その結果、放熱ロスを抑制し庫内全体を均一な温度分布とした効率的な被加熱物の加熱が可能となり、加熱室の予熱や加熱調理のスピードを向上させることができる。   The heating device according to the present invention can be concentrated in the central direction of the heating chamber by the hot air from the outlet at the position where the substantially L-shaped and point-symmetric partition plate is provided. As a result, it is possible to efficiently heat the object to be heated with the heat dissipation loss being suppressed and the entire interior having a uniform temperature distribution, and the heating chamber preheating and cooking speed can be improved.

図２、３に示されるように、これら仕切板３２、３３は、後壁１９に対して略４５度の角度で外向きに傾斜するように取り付けられる。これらの仕切板３２、３３は、金属板等をくの字状に折り曲げられて形成された取付け代を、カシメや溶接により後壁１９に圧着固定される。   As shown in FIGS. 2 and 3, the partition plates 32 and 33 are attached to the rear wall 19 so as to incline outward at an angle of approximately 45 degrees. These partition plates 32 and 33 are fixed to the rear wall 19 by crimping or welding an attachment allowance formed by bending a metal plate or the like into a U shape.

図３に示されるように、左上と右下の仕切板３２、３３は、長辺が循環ファンの円周と接する角度で後壁とは略４５度の角度をなし、短片が長辺と略９０度の角度で形成され後壁１９と略９０度となり、長さとしては、後壁１９の中央付近に左上吹出口２９、右下吹出口３０を覆う程度の長さのものとして設けられる。   As shown in FIG. 3, the upper left and lower right partition plates 32 and 33 are formed such that the long sides are in contact with the circumference of the circulation fan and form an angle of about 45 degrees with the rear wall, and the short pieces are substantially the long sides. It is formed at an angle of 90 degrees and is approximately 90 degrees with the rear wall 19, and the length is provided so as to cover the upper left outlet 29 and the lower right outlet 30 near the center of the rear wall 19.

加熱室１３の内容量を適度に確保しつつ、熱源室２３とモータ３１の奥行き寸法を含めた本体１１の奥行き寸法を小さくするためには、熱源室２３の奥行き寸法だけを小さくする必要がある。   In order to reduce the depth dimension of the main body 11 including the depth dimensions of the heat source chamber 23 and the motor 31 while appropriately securing the internal volume of the heating chamber 13, it is necessary to reduce only the depth dimension of the heat source chamber 23. .

本実施の形態では、奥行き寸法が小さくても送風性能が劣化しない送風ファン２５を用い、その分、モータ３１に近接した部分では筐体２２を加熱室１３側にへこませた形状としている。このようにして、熱源室２３とモータ３１とを合わせた奥行き方向の寸法を小さくしている。   In the present embodiment, the blower fan 25 is used in which the blower performance does not deteriorate even if the depth dimension is small, and the housing 22 is dented toward the heating chamber 13 in the portion close to the motor 31 correspondingly. In this way, the size in the depth direction of the heat source chamber 23 and the motor 31 is reduced.

モータ３１に近接した部分以外の熱源室２３の奥行き寸法は、少し大きくなっており、ヒータ２４や左右の仕切板３１、３２の周辺における空気流の通路が確保されている。ヒータ２４は送風ファン２５よりもやや後方に配置されている。また、上からの輻射加熱作用を実現するためのヒータとして近赤外線を放射するアルゴンランプヒータ３４と遠赤外線を放射するミラクロンヒータ３５を設けている。   The depth dimension of the heat source chamber 23 other than the portion close to the motor 31 is slightly larger, and an air flow passage around the heater 24 and the left and right partition plates 31 and 32 is secured. The heater 24 is disposed slightly behind the blower fan 25. In addition, an argon lamp heater 34 that emits near infrared rays and a miraclon heater 35 that emits far infrared rays are provided as heaters for realizing the radiation heating action from above.

以下、本実施の形態にかかる加熱装置の動作について説明する。   Hereinafter, the operation of the heating device according to the present embodiment will be described.

例えば、オーブン調理の場合、クッキー等の被加熱物１２が載せられた調理皿２１を、加熱室１３の左右壁面に設けられた支持部２０に係止させて、後壁１９に接触するまで押し込み、ドア１４を閉め、本体１１の前面に設けられた操作部（図示せず）上の所定ボタンを操作すると、オーブン調理が開始される。   For example, in the case of oven cooking, the cooking tray 21 on which the object to be heated 12 such as a cookie is placed is locked to the support portions 20 provided on the left and right wall surfaces of the heating chamber 13 and pushed in until it contacts the rear wall 19. When the door 14 is closed and a predetermined button on an operation unit (not shown) provided on the front surface of the main body 11 is operated, oven cooking is started.

この操作部で被加熱物１２の加熱時間や加熱温度などが設定でき、操作部から入力され
た指示に基づき、マイコンからなる制御部は、ヒータ２４、モータ３１等を制御する。 A heating time, a heating temperature, and the like of the article to be heated 12 can be set by the operation unit, and a control unit including a microcomputer controls the heater 24, the motor 31, and the like based on an instruction input from the operation unit.

モータ３１の回転駆動により送風ファン２５が回転を始めると、送風ファン２５から渦巻き状外向きに吹き出した空気流は、ヒータ２４の熱により高温に熱せられた熱風となり左上仕切板３２と右下仕切板３３のある場所で略４５度の角度を持って各吹出口から庫内中央すなわち、被加熱物１２の方向に向かうようになる。   When the blower fan 25 starts rotating by the rotation of the motor 31, the air flow blown outwardly from the blower fan 25 becomes hot air heated to a high temperature by the heat of the heater 24, and the upper left partition plate 32 and the lower right partition. At a place where the plate 33 is present, the air flows from each outlet to the center of the cabinet, that is, in the direction of the object to be heated 12 with an angle of approximately 45 degrees.

ヒータ２４により加熱された熱風のうち、上方への熱風は上吹出口２７から、下方への熱風は下吹出口２８から、それぞれ加熱室１３に吹き出す。これらの熱風は、送風ファン２５の回転方向に沿った渦巻き状外向きの風向を持っているので、上吹出口２７からの熱風は天面１８または右側壁１６方向に、下吹出口２８からの熱風は底面１７または左側壁１５方向にそれぞれ向かって流れる。   Of the hot air heated by the heater 24, hot air upward is blown out from the upper outlet 27, and hot air downward is blown out from the lower outlet 28 into the heating chamber 13. Since these hot air has a spiral outward wind direction along the rotation direction of the blower fan 25, the hot air from the upper outlet 27 is directed from the lower outlet 28 toward the top surface 18 or the right side wall 16. Hot air flows toward the bottom surface 17 or the left side wall 15 respectively.

以上、本実施の形態によれば、熱源室２３から左上吹出口２９と右下吹出口３０を通って加熱室１３に吹き出す熱風を被加熱物１２の上下から集中させ対流熱伝達により加熱することができる。その結果、熱風が壁面ばかりを加熱することによる放熱ロスを抑制した効率的な被加熱物の加熱が可能となり、加熱室の予熱や加熱調理のスピードを向上させることができる。   As described above, according to the present embodiment, the hot air blown from the heat source chamber 23 through the upper left outlet 29 and the lower right outlet 30 to the heating chamber 13 is concentrated from above and below the object 12 to be heated by convective heat transfer. Can do. As a result, it is possible to efficiently heat the object to be heated while suppressing the heat radiation loss caused by the hot air heating only the wall surface, and the preheating of the heating chamber and the cooking speed can be improved.

また、熱源室２３の薄型化にも有利なので、加熱室の容量を確保しつつも全体の奥行き寸法が小さく、かつ、省エネ性能の高い加熱装置を提供できる。   Further, since the heat source chamber 23 is advantageous in thickness reduction, it is possible to provide a heating device having a small overall depth dimension and high energy saving performance while ensuring the capacity of the heating chamber.

なお、本実施の形態では熱源室２３から左上吹出口２９と右下吹出口３０を通って加熱室１３に吹き出す熱風を被加熱物１２に集中させる例について説明したが、図５に示すように右上仕切板３６、左下仕切板３７により右上吹出口３８と左下吹出口３９を通って加熱室１３に吹き出す熱風を被加熱物１２の上下から集中させる構成としても同様の効果を発揮することができる。   In the present embodiment, an example has been described in which hot air blown from the heat source chamber 23 through the upper left outlet 29 and the lower right outlet 30 to the heating chamber 13 is concentrated on the object to be heated 12, as shown in FIG. A similar effect can be achieved by a configuration in which the hot air blown out to the heating chamber 13 through the upper right outlet 38 and the lower left outlet 39 by the upper right partition plate 36 and the lower left partition plate 37 is concentrated from above and below the heated object 12. .

さらに、本実施の形態では、ヒータ２４として、環状のシーズヒータが使用されるが、シーズヒータの表面に放熱フィンを設けたものであっても良く、同様の効果が得られる。   Further, in the present embodiment, an annular sheathed heater is used as the heater 24, but a heat dissipation fin may be provided on the surface of the sheathed heater, and the same effect can be obtained.
