Description

本発明は、加熱調理器具を載置するトッププレートを備えると共に、このトッププレートの下に配設された加熱ユニットを備えてなる加熱調理器に関する。   The present invention relates to a cooking device including a top plate on which a cooking device is placed and a heating unit disposed below the top plate.

この種の加熱調理器である例えば誘導加熱調理器においては、鍋等の加熱調理器具の温度を検出する温度センサを、加熱ユニットを構成する加熱コイルの中央部に配設するように構成されている。この場合、温度センサは、加熱調理器具の温度をトッププレートを介して検出している。しかし、加熱調理器具の底部の形状がフラットでないもの（例えば底部の中央部が少し凹状となったもの）の場合、加熱調理器具の温度がトッププレートに伝わり難くなり、温度センサの温度検出が遅れるという不具合があった。   In an induction heating cooker, for example, this type of heating cooker, a temperature sensor that detects the temperature of a cooking utensil such as a pan is arranged to be disposed at the center of a heating coil that constitutes the heating unit. Yes. In this case, the temperature sensor detects the temperature of the cooking device via the top plate. However, when the shape of the bottom of the cooking utensil is not flat (for example, the center of the bottom is slightly concave), the temperature of the cooking utensil becomes difficult to be transmitted to the top plate, and the temperature detection of the temperature sensor is delayed. There was a problem that.

このような不具合を解消する構成として、加熱コイルを内周側加熱コイルと外周側加熱コイルとから構成し、これら内周側加熱コイルと外周側加熱コイルとの間の空隙部に温度センサを配設した構成がある。この構成の場合、加熱調理器具の底部の中央部が少し凹状であっても、加熱調理器具の底部がトッププレートに接触する部位に温度センサが配置されていることから、加熱調理器具の温度がトッププレートを介して温度センサに伝わり易くなり、温度センサの温度検出が早くなる。   In order to eliminate such problems, the heating coil is composed of an inner peripheral heating coil and an outer peripheral heating coil, and a temperature sensor is arranged in the gap between the inner peripheral heating coil and the outer peripheral heating coil. There is a configuration. In the case of this configuration, even if the central portion of the bottom of the cooking utensil is slightly concave, the temperature sensor is disposed at the site where the bottom of the cooking utensil contacts the top plate. It becomes easy to be transmitted to the temperature sensor through the top plate, and the temperature detection of the temperature sensor is accelerated.

尚、加熱コイルを内周側加熱コイルと外周側加熱コイルとから構成した加熱調理器の一例として、特許文献１に記載された加熱調理器がある。
特公平７−１１９８３号公報 In addition, there exists a heating cooker described in patent document 1 as an example of the heating cooker which comprised the heating coil from the inner peripheral side heating coil and the outer peripheral side heating coil.
Japanese Patent Publication No.7-11983

上記特許文献１に記載された構成の場合、加熱コイルを支持するコイルベース（加熱コイル支持台）には、多数の開口部（通気口）が形成されており、冷却装置から送風された冷却風が上記開口部を通過して加熱コイルに吹き付けられるように構成されており、これにより、加熱コイルが十分冷却されるようになっている。しかし、上記特許文献１の構成においては、コイルベースにおける内周側加熱コイルと外周側加熱コイルとの間の空隙部に対応する部分にも、多数の開口部が形成されているので、開口部を通過した冷却風によって温度センサやトッププレートが冷却されてしまう。このため、温度センサによって、加熱調理器具の温度を正確に検出することができないという問題点があった。   In the case of the configuration described in Patent Document 1, the coil base (heating coil support) that supports the heating coil has a large number of openings (vent holes), and the cooling air blown from the cooling device. Passes through the opening and is sprayed onto the heating coil, so that the heating coil is sufficiently cooled. However, in the configuration of Patent Document 1, a large number of openings are formed in a portion corresponding to the gap between the inner peripheral heating coil and the outer peripheral heating coil in the coil base. The temperature sensor and the top plate are cooled by the cooling air that has passed through. For this reason, there has been a problem that the temperature of the cooking device cannot be accurately detected by the temperature sensor.

そこで、本発明の目的は、トッププレート上に載置された加熱調理器具の温度を正確に検出することができる加熱調理器を提供するにある。   Then, the objective of this invention is providing the heating cooker which can detect the temperature of the heating cooking appliance mounted on the top plate correctly.

本発明の加熱調理器は、加熱調理器の本体と、この本体の上面を構成し加熱調理器具を載置するトッププレートと、このトッププレートの下に配設され前記加熱調理器具を加熱する加熱ユニットと、この加熱ユニットを冷却する冷却手段とを備えてなるものにおいて、前記加熱ユニットを、内周側加熱コイルと外周側加熱コイルとからなる加熱コイルと、この加熱コイルを支持するコイルベースとから構成し、前記内周側加熱コイルと前記外周側加熱コイルとの間の空隙部に前記加熱調理器具の温度を検出する温度センサを配設し、そして、前記コイルベースに、前記加熱コイルを直接冷却するための開口部を設けると共に、前記温度センサに冷却風が直接当たらないようにするための壁部を設けるように構成したところに特徴を有する。   The heating cooker of the present invention includes a main body of the heating cooker, a top plate that constitutes an upper surface of the main body and on which the heating cooker is placed, and heating that heats the heating cooker disposed below the top plate. A heating unit including an inner peripheral side heating coil and an outer peripheral side heating coil; and a coil base that supports the heating coil. A temperature sensor for detecting the temperature of the cooking device is disposed in a gap between the inner peripheral heating coil and the outer peripheral heating coil, and the heating coil is disposed on the coil base. It is characterized in that an opening for direct cooling is provided and a wall for preventing the cooling air from directly hitting the temperature sensor is provided.

本発明は、コイルベースに、加熱コイルを直接冷却するための開口部を設けると共に、温度センサに冷却風が直接当たらないようにするための壁部を設ける構成としたので、温度センサが冷却風により冷却されることがなくなり、加熱調理器具の温度を正確に検出することができるという効果を奏する。   According to the present invention, the coil base is provided with the opening for directly cooling the heating coil and the wall for preventing the cooling air from directly hitting the temperature sensor. It is no longer cooled by this, and there is an effect that the temperature of the cooking device can be accurately detected.

When the heating coil 8 is placed and attached to the coil base 10, the portion corresponding to the gap 17 between the inner peripheral heating coil 15 and the outer peripheral heating coil 16 in the coil base 10 is annular. Wall portion 10b is formed. In the case of this configuration, the gap portion 17 between the inner peripheral heating coil 15 and the outer peripheral heating coil 16 is blocked by the wall portion 10 b of the coil base 10, and cooling air from below passes through the void portion 17. Is configured to disappear.

ここで、送風装置１２からの冷却風を加熱ユニット６、７（加熱コイル８、９）の下方まで案内するダクト１３に形成された吹出口１３ａは、コイルベース１０の開口部１０ａに対応する部位に配設されるように構成されている（図１参照）。
また、図１及び図２に示すように、コイルベース１０の壁部１０ｂのうちの手前の部分、即ち、内周側加熱コイル１５の中心部を通り前後方向に延びる直線上であって内周側加熱コイル１５と外周側加熱コイル１６との間に位置する部分には、加熱調理器具の温度を検出する温度センサ１８が配設されている。この温度センサ１８は、ケース（感熱部）１９と、このケース１９内に収容された図示しない温度検知素子とから構成されている。 Here, the air outlet 13 a formed in the duct 13 that guides the cooling air from the blower 12 to the lower side of the heating units 6 and 7 (heating coils 8 and 9) is a portion corresponding to the opening 10 a of the coil base 10. (Refer to FIG. 1).
Further, as shown in FIGS. 1 and 2, the front portion of the wall portion 10 b of the coil base 10, that is, a straight line extending in the front-rear direction through the center portion of the inner peripheral heating coil 15, and the inner periphery A temperature sensor 18 for detecting the temperature of the cooking device is disposed in a portion located between the side heating coil 15 and the outer peripheral side heating coil 16. The temperature sensor 18 includes a case (heat sensitive portion) 19 and a temperature detection element (not shown) housed in the case 19.

上記ケース１９は、図５及び図６に示すように、トッププレート３の下面に当接する板部１９ａと、この板部１９ａの下面に設けられた円筒状の収容部１９ｂとから構成されている。収容部１９ｂの下部からリード線２０が引き出されている。
そして、温度センサ１８は、図５及び図６に示すように、ホルダー２１内に弾性体２２、断熱板２３及び断熱材２４と一緒に収容されると共に、ホルダー２１をコイルベース１０の壁部１０ｂに取り付けることにより、コイルベース１０に取り付けられている。ホルダー２１をコイルベース１０の壁部１０ｂに取り付けるに当たっては、ホルダー２１に突設された２個の係合爪２１ａ（図６では１個のみ図示）を壁部１０ｂに形成された係合孔（図示しない）に係合させるように構成している。 As shown in FIGS. 5 and 6, the case 19 includes a plate portion 19a that contacts the lower surface of the top plate 3, and a cylindrical housing portion 19b provided on the lower surface of the plate portion 19a. . The lead wire 20 is drawn out from the lower part of the accommodating part 19b.
As shown in FIGS. 5 and 6, the temperature sensor 18 is accommodated in the holder 21 together with the elastic body 22, the heat insulating plate 23 and the heat insulating material 24, and the holder 21 is attached to the wall portion 10 b of the coil base 10. It is attached to the coil base 10 by attaching to the coil base 10. When attaching the holder 21 to the wall portion 10b of the coil base 10, two engagement claws 21a (only one is shown in FIG. 6) projecting from the holder 21 are formed in engagement holes ( (Not shown).

この構成の場合、弾性体２２は、温度センサ１８のケース１９の板部１９ａをトッププレート３の裏面に接触するように付勢する機能を有している。そして、弾性体２２は、温度センサ１８のケース１９のうちのトッププレート３に接触する部分（板部１９ａ）以外の部分である収容部１９ｂを覆うように配設されている。また、断熱材２４は、温度センサ１８のケース１９の板部１９ａと上記弾性体２２との間に設けられており、該板部１９ａとその周辺のトッププレート３の下面を覆うように配設されている。尚、弾性体２２は例えばシリコンゴムで形成され、断熱板２３は例えばマイカで形成され、断熱材２４は耐熱性を有する不織布等で形成されている。   In the case of this configuration, the elastic body 22 has a function of urging the plate portion 19 a of the case 19 of the temperature sensor 18 so as to contact the back surface of the top plate 3. And the elastic body 22 is arrange | positioned so that the accommodating part 19b which is parts other than the part (plate part 19a) of the case 19 of the temperature sensor 18 which contacts the top plate 3 may be covered. The heat insulating material 24 is provided between the plate portion 19a of the case 19 of the temperature sensor 18 and the elastic body 22, and is disposed so as to cover the lower surface of the plate portion 19a and the surrounding top plate 3. Has been. The elastic body 22 is made of, for example, silicon rubber, the heat insulating plate 23 is made of, for example, mica, and the heat insulating material 24 is made of a non-woven fabric having heat resistance.

また、図５に示すように、コイルベース１０の壁部１０ｂの下面における温度センサ１８が配置された部分に対応する部位には、防風材２５が配設されている。尚、コイルベース１０の下面には、図４に示すように、複数本のフェライト２６が中心から放射状に取り付けられている。   Further, as shown in FIG. 5, a windproof material 25 is disposed in a portion corresponding to a portion where the temperature sensor 18 is disposed on the lower surface of the wall portion 10 b of the coil base 10. As shown in FIG. 4, a plurality of ferrites 26 are attached to the lower surface of the coil base 10 radially from the center.

このような構成の本実施例においては、加熱ユニット６、７において、内周側加熱コイル１５と外周側加熱コイル１６との間の空隙部１７に鍋Ａの温度を検出する温度センサ１８を配設すると共に、コイルベース１０、１１に、加熱コイル８、９を直接冷却するための開口部１０ａ、１１ａを設けると共に、温度センサ１８に冷却風が直接当たらないようにするための壁部１０ｂ、１１ｂを設けるように構成した。この構成の場合、コイルベース１０、１１ｂの壁部１０ｂ、１１ｂにより温度センサ１８に冷却風が直接当たらなくなるから、温度センサ１８による鍋Ａの温度の検出精度を高くすることができる。   In the present embodiment having such a configuration, in the heating units 6 and 7, a temperature sensor 18 for detecting the temperature of the pan A is arranged in the gap portion 17 between the inner peripheral heating coil 15 and the outer peripheral heating coil 16. And opening portions 10a and 11a for directly cooling the heating coils 8 and 9 in the coil bases 10 and 11, and a wall portion 10b for preventing the cooling air from directly hitting the temperature sensor 18. 11b was provided. In the case of this configuration, the cooling air is not directly applied to the temperature sensor 18 by the wall portions 10b and 11b of the coil bases 10 and 11b, so that the temperature sensor 18 can detect the temperature of the pan A with high accuracy.

また、上記実施例では、弾性体２２で温度センサ１８を覆うように構成したので、加熱コイル８、９を冷却した後の冷却風が流れ込んで温度センサ１８に当たることを防止することができる。加えて、上記実施例においては、断熱材２４によって温度センサ１８を覆うと共に、トッププレート３の下面のうちの温度センサ１８周辺部分を覆うように構成したので、加熱コイル８、９を冷却した後の冷却風が流れ込んで温度センサ１８やその周辺部分（トッププレート３）に当たることをより一層防止することができる。   Moreover, in the said Example, since it comprised so that the temperature sensor 18 might be covered with the elastic body 22, it can prevent that the cooling air after cooling the heating coils 8 and 9 flows in and hits the temperature sensor 18. FIG. In addition, in the above embodiment, since the temperature sensor 18 is covered with the heat insulating material 24 and the peripheral portion of the temperature sensor 18 on the lower surface of the top plate 3 is covered, the heating coils 8 and 9 are cooled. It is possible to further prevent the cooling air from flowing in and hitting the temperature sensor 18 and its peripheral portion (top plate 3).

更に、上記実施例では、コイルベース１０、１１の壁部１０ｂ、１１ｂの下面における温度センサ１８が配置された部分に対応する部位に、防風材２５を配設したので、壁部１０ｂ、１１ｂに形成された温度センサ１８のリード線２０を通す孔を上記防風材２５で塞ぐことができる。これにより、加熱コイル８、９を冷却した後の冷却風が流れ込んで温度センサ１８を冷却することをより一層防止できる。   Furthermore, in the said Example, since the wind-proof material 25 was arrange | positioned in the site | part corresponding to the part by which the temperature sensor 18 is arrange | positioned in the lower surface of the wall parts 10b and 11b of the coil bases 10 and 11, the wall parts 10b and 11b are provided. The hole through which the lead wire 20 of the formed temperature sensor 18 passes can be closed with the windproof material 25. Thereby, it is possible to further prevent the cooling air after cooling the heating coils 8 and 9 from flowing and cooling the temperature sensor 18.

ところで、片手鍋を使用する場合、把手を手前側におくことで、鍋が前側に傾く傾向がある。これに対して、上記実施例では、温度センサ１８を、内周側加熱コイル１５と外周側加熱コイル１６との間の空隙部１７における手前の部位（図２参照）に配設したので、他の部位に温度センサを配設する構成に比べて、上記片手鍋の温度を正確に検出し易くなる。   By the way, when using a one-handed pan, the pan tends to tilt forward by placing the handle on the front side. On the other hand, in the above-described embodiment, the temperature sensor 18 is disposed in the front portion (see FIG. 2) in the gap portion 17 between the inner peripheral side heating coil 15 and the outer peripheral side heating coil 16. Compared with the structure which arrange | positions a temperature sensor in this site | part, it becomes easy to detect the temperature of the said one-handed pan correctly.

図７は、本発明の第２の実施例を示すものである。尚、第１の実施例と同一部分には、同一符号を付している。この第２の実施例においては、温度センサ１８を、内周側加熱コイル１５と外周側加熱コイル１６との間の空隙部１７に等間隔に４個配設した。これ以外の構成は、第１の実施例の構成と同じである。   FIG. 7 shows a second embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals. In the second embodiment, four temperature sensors 18 are arranged at equal intervals in the gap 17 between the inner peripheral heating coil 15 and the outer peripheral heating coil 16. The other configuration is the same as that of the first embodiment.

上記第２の実施例においても、第１の実施例とほぼ同じ作用効果を得ることができるが、特に、温度センサ１８を空隙部１７に等間隔に４個配設したので、加熱調理器具（鍋）の置き方が多少悪くても（加熱コイル８、９の中心に対して鍋の中心がランダムに偏心していても）、加熱調理器具（鍋）の温度を正確に検出することができる。また、温度センサが１個であると、鍋の底が変形していたり、鍋を置いた位置が温度センサから外れていたりすると、検出した温度に誤差が発生する。これに対して、第２の実施例のように、４個の温度センサ１８を設けているので、最も高い温度を検出している温度センサ１８が鍋の温度を正確に検出していると、判断することができる。   In the second embodiment, substantially the same effect as that of the first embodiment can be obtained. In particular, since four temperature sensors 18 are arranged in the gap portion 17 at equal intervals, Even if the method of placing the pan is somewhat worse (even if the center of the pan is randomly eccentric with respect to the center of the heating coils 8 and 9), the temperature of the cooking device (pan) can be accurately detected. In addition, if the temperature sensor is one, an error occurs in the detected temperature if the bottom of the pan is deformed or if the position where the pan is placed is out of the temperature sensor. On the other hand, since the four temperature sensors 18 are provided as in the second embodiment, when the temperature sensor 18 that detects the highest temperature accurately detects the temperature of the pan, Judgment can be made.

尚、上記第２の実施例では、４個の温度センサ１８を等間隔に配設したが、これに限られるものではなく、２個、３個または５個以上の温度センサ１８を等間隔に配設するように構成しても良い。   In the second embodiment, the four temperature sensors 18 are arranged at regular intervals. However, the present invention is not limited to this, and two, three, or five or more temperature sensors 18 are arranged at regular intervals. You may comprise so that it may arrange | position.

Arranged.

上述した以外の構成は、第１の実施例の構成と同じである。従って、第３の実施例においても、第１の実施例とほぼ同じ作用効果を得ることができるが、特に、空隙部１７において２個の温度センサ１８を前後に配設したので、鍋を前後にずらして置いたような場合でも、鍋の温度を正確に検出することができる。   The configuration other than that described above is the same as the configuration of the first embodiment. Accordingly, in the third embodiment, substantially the same operational effects as in the first embodiment can be obtained, but in particular, since the two temperature sensors 18 are arranged in the front and rear in the gap portion 17, the pan is moved forward and backward. Even in the case that the pan is placed in the position, the temperature of the pan can be accurately detected.

尚、トッププレート３の上面には、加熱コイル７、８の位置、即ち、鍋を置く位置を示すリング状のマーク２７（第４の実施例を示す図９参照）が印刷されており、このマーク２７を目安にしてユーザーは鍋をトッププレート３上に置くようにしているが、鍋を置くときに、奥側（後部）が死角になるため、鍋は前後方向に置く位置がずれやすい傾向がある。このため、第３の実施例のように、温度センサ１８を配設すると、最少の個数の温度センサ１８で有効な効果を得ることができる。尚、上記第３の実施例では、コイルベース１０の中心部にも、温度センサ１８を配設したが、これを省略しても良い。   A ring-shaped mark 27 (see FIG. 9 showing the fourth embodiment) indicating the position of the heating coils 7 and 8, that is, the position where the pan is placed, is printed on the upper surface of the top plate 3. The user puts the pan on the top plate 3 by using the mark 27 as a guide, but when placing the pan, the back side (rear part) becomes a blind spot, so the pan tends to be displaced in the front-rear direction. There is. For this reason, when the temperature sensors 18 are arranged as in the third embodiment, an effective effect can be obtained with the minimum number of temperature sensors 18. In the third embodiment, the temperature sensor 18 is also disposed at the center of the coil base 10, but this may be omitted.

図９は、本発明の第４の実施例を示すものである。尚、第３の実施例と同一部分には、同一符号を付している。この第４の実施例では、図９に示すように、トッププレート３の上面に、加熱コイル７、８の位置、即ち、鍋を置く位置を示すリング状のマーク２７を印刷すると共に、温度センサ１８の配設位置を示すマーク２８を印刷するように構成した。尚、中心部に配設した温度センサ１８については、その位置を示すマークを印刷していない。   FIG. 9 shows a fourth embodiment of the present invention. The same parts as those in the third embodiment are denoted by the same reference numerals. In the fourth embodiment, as shown in FIG. 9, a ring-shaped mark 27 indicating the position of the heating coils 7 and 8, that is, the position where the pan is placed is printed on the upper surface of the top plate 3, and the temperature sensor. The mark 28 indicating the arrangement position of 18 is printed. In addition, about the temperature sensor 18 arrange | positioned in the center part, the mark which shows the position is not printed.

上述した以外の構成は、第３の実施例の構成と同じである。従って、第４の実施例においても、第３の実施例とほぼ同じ作用効果を得ることができるが、特に、第４の実施例では、温度センサ１８の配設位置を示すマーク２８をトッププレート３上に印刷するように構成したので、ユーザーは温度センサ１８の位置を明確に認識することになり、鍋の置き方が良くなる。このため、鍋の温度の検出がより一層正確になる。   The configuration other than that described above is the same as the configuration of the third embodiment. Therefore, in the fourth embodiment, substantially the same function and effect as in the third embodiment can be obtained. In particular, in the fourth embodiment, the mark 28 indicating the arrangement position of the temperature sensor 18 is provided on the top plate. Since the printer is configured to print on 3, the position of the temperature sensor 18 is clearly recognized by the user, and the placing of the pan is improved. For this reason, the detection of the temperature of the pan becomes even more accurate.

尚、上記した各実施例においては、加熱コイル８、９を、内周側加熱コイル１５と外周側加熱コイル１６とで構成して１つの空隙部１７を設けるように構成したが、これに限られるものではなく、３つ以上の部分加熱コイルで構成して２つ以上の空隙部を設けるように構成しても良い。   In each of the above-described embodiments, the heating coils 8 and 9 are configured by the inner peripheral side heating coil 15 and the outer peripheral side heating coil 16 so as to provide one gap portion 17.
