Description

本発明は、オーブンレンジ、電気オ−ブン等の加熱調理器に関するものである。   The present invention relates to a cooking device such as a microwave oven or an electric oven.

従来の加熱調理器は、加熱室内にヒータおよび回転皿が設けられ、その上下左右の内壁面にはセラミック板を組み合わせてなる断熱壁が取り付けられている。この断熱壁は、加熱室の最外部に設けられた金属製の枠体の内側に嵌合され、押さえ金具により固定されている（例えば、特許文献１参照）。   In a conventional cooking device, a heater and a rotating dish are provided in a heating chamber, and heat insulating walls formed by combining ceramic plates are attached to upper, lower, left and right inner wall surfaces. The heat insulating wall is fitted inside a metal frame provided at the outermost part of the heating chamber and is fixed by a pressing metal fitting (for example, see Patent Document 1).

特開平１１−１１８１５８号公報Japanese Patent Laid-Open No. 11-118158

しかしながら、前述した従来の加熱調理器では、セラミック板の断熱壁を押さえ金具で固定しているため構造が複雑となり、しかも、押さえ金具が断熱壁（セラミック板）内に密着して露出し、その断熱壁が金属製の枠体に密着された状態になっているため、断熱効果が良いとはいえなかった。   However, in the above-mentioned conventional cooking device, the structure is complicated because the heat insulating wall of the ceramic plate is fixed with the holding metal, and the holding metal is closely exposed in the heat insulating wall (ceramic plate). Since the heat insulating wall is in close contact with the metal frame, it cannot be said that the heat insulating effect is good.

また、前記の加熱調理器を用いて、例えばヒータを複数の面に設けた場合、ヒータを有する面に対してセラミック板が存在するため、ヒータからの放射熱がセラミック板に吸収され易くなり加熱室内の温度立ち上がりが良くなかった。また、マグネトロンを用いた場合には、マグネトロンを有する面にセラミック板が存在すると、マイクロ波がセラミック板に吸収され、マイクロ波による加熱効率が良くなかった。   In addition, when the heater is provided on a plurality of surfaces using the heating cooker, for example, since the ceramic plate exists on the surface having the heater, the radiant heat from the heater is easily absorbed by the ceramic plate. The temperature rise in the room was not good. When a magnetron is used, if a ceramic plate is present on the surface having the magnetron, the microwave is absorbed by the ceramic plate, and the heating efficiency by the microwave is not good.

本発明は、前記のような課題を解決するためになされたものであり、簡単な構造で断熱効果が高く、より遠赤効果のある加熱調理器を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a cooking device having a simple structure, a high heat insulating effect, and a far-red effect.

本発明に係る加熱調理器は、調理器本体と、調理器本体内に設けられ調理物を収納して加熱調理するための加熱室と、調理物を加熱する加熱手段と、加熱室の内壁の少なくとも２面に空隙部を形成して設けられたセラミック板と、セラミック板の加熱室内に露出する面に設けられた凹凸とを備え、セラミック板の表面がコーティングによって平滑に仕上げられている。 A cooking device according to the present invention includes a cooking device body, a heating chamber provided in the cooking device body for storing and cooking food, heating means for heating the cooking material, and an inner wall of the heating chamber. The ceramic plate is provided with a gap formed on at least two surfaces, and the unevenness provided on the surface exposed to the heating chamber of the ceramic plate, and the surface of the ceramic plate is smoothly finished by coating.

本発明においては、セラミック板の加熱室内に露出する面に凹凸を設けたので、セラミック板の表面積が大きくなり、このため、遠赤外線の放射量が増加する。また、そのセラミック板の表面がコーティングによって平滑に仕上げられているので、セラミック板に付着した汚れ等が拭き取り易くなり、加熱室内の清掃性が向上する。
In the present invention, since the unevenness is provided on the surface of the ceramic plate exposed in the heating chamber, the surface area of the ceramic plate increases, and thus the amount of radiation of far infrared rays increases . Further, since the surface of the ceramic plate is smoothed by the coating, dirt and the like attached to the ceramic plate can be easily wiped off, and the cleanability in the heating chamber is improved.

実施の形態１．
図１は本発明の実施の形態１に係る加熱調理器のオーブンレンジを示す正面の断面図、図２はオーブンレンジの加熱室に設けられたセラミック板の形状を示す断面図、図３はセラミック板の拡大断面図である。
図１において、オーブンレンジ本体１の内部に、前面が開口された加熱室２が設けられている。この加熱室２は、天面、奥面、底面および左右側面がステンレス板等で形成された枠体３と、その枠体３の前面開口を開閉自在に覆うドア（図示せず）とで区画形成されている。枠体３の左右側面にはプレス成形により２段階に窪んだ凹部４が形成され、各凹部４にはセラミック板５がそれぞれ固着されている。加熱室２の底面外側には調理物を加熱するヒータ９が設置され、また、図示していないが、マイクロ波を加熱室２内に供給するマグネトロンが設けられている。 Embodiment 1 FIG.
1 is a front sectional view showing a microwave oven of a heating cooker according to Embodiment 1 of the present invention, FIG. 2 is a sectional view showing the shape of a ceramic plate provided in a heating chamber of the microwave oven, and FIG. 3 is a ceramic. It is an expanded sectional view of a board.
In FIG. 1, a heating chamber 2 having an open front surface is provided inside a microwave oven body 1. The heating chamber 2 is divided into a frame 3 whose top surface, back surface, bottom surface, and left and right side surfaces are formed of stainless steel plates, and a door (not shown) that covers the front opening of the frame 3 so as to be openable and closable. Is formed. The left and right side surfaces of the frame 3 are formed with depressions 4 that are recessed in two stages by press molding, and ceramic plates 5 are fixed to the respective depressions 4. A heater 9 that heats the food is installed outside the bottom surface of the heating chamber 2, and a magnetron that supplies microwaves into the heating chamber 2 is provided, although not shown.

前述したセラミック板５は、例えば、厚みが４ｍｍで、平面形状が長方形あるいは正方形に形成され、金属製あるいはセラミック製の調理皿８を支持するための棚部７が形成されている。素材としては、ムライト、コーディライト系セラミックで、酸化ケイ素（ＳｉＯ2 ）、酸化アルミニウム（Ａｌ2Ｏ3）、酸化マグネシウム（ＭｇＯ）、酸化ジルコニウム（ＺｒＯ2 ）等を主成分とするセラミック板５で構成されている。なお、これら素材に代えて、陶器、天然石、結晶化ガラス等などでも良い。 The ceramic plate 5 described above has, for example, a thickness of 4 mm and a planar shape of a rectangle or a square, and a shelf 7 for supporting a metal or ceramic cooking dish 8 is formed. The ceramic plate 5 is made of mullite or cordierite ceramic as a material and mainly contains silicon oxide (SiO 2 ), aluminum oxide (Al 2 O 3 ), magnesium oxide (MgO), zirconium oxide (ZrO 2 ), etc. It is configured. Instead of these materials, pottery, natural stone, crystallized glass, etc. may be used.

このセラミック板５は、枠体３の左右側面に形成された凹部４の１段目の段部に嵌め込まれた状態になるように、外周縁部が枠体３の左右側面に接着剤１０（例えばシリコン接着剤）で固着されている。このセラミック板５の設置により、凹部４の２段目の段部となる内側側面との間に、空気層が介在する空隙部６が形成されている。この空隙部６の寸法は、断熱層とするために２〜６ｍｍ以下になっている。空隙部６の寸法が大きいとセラミック板５の裏面と枠体３に形成された凹部４の内側側面との温度差により、密閉された空気層での垂直方向の自然対流が発生して熱移動となり断熱にならない。一般的に６ｍｍを超えると熱対流が発生し、また、空隙部６の寸法が小さいと熱伝導となり断熱にならない。   The ceramic plate 5 has an outer peripheral edge portion attached to the left and right side surfaces of the frame body 3 so that the ceramic plate 5 is fitted in the first step portion of the recess 4 formed on the left and right side surfaces of the frame body 3. For example, it is fixed with a silicon adhesive. By installing this ceramic plate 5, a gap portion 6 is formed between the inner side surface, which is the second step portion of the recess 4, with an air layer interposed. The size of the gap 6 is 2 to 6 mm or less in order to obtain a heat insulating layer. If the size of the gap 6 is large, a natural convection in the vertical direction in the sealed air layer occurs due to a temperature difference between the back surface of the ceramic plate 5 and the inner side surface of the recess 4 formed in the frame 3, and heat transfer. It does not become thermal insulation. In general, if it exceeds 6 mm, heat convection occurs, and if the size of the gap 6 is small, heat conduction occurs and heat insulation does not occur.

そこで、前述の如く空隙部６を２〜６ｍｍ以下とし、さらに、図２および図３に示すようにセラミック板５の加熱室内に露出する面（棚部７も含む）に０．５ｍｍ程度の微小の凹凸１１を設けている。この凹凸１１により、セラミック板５の空気と接触する面積は、表面が平滑に処理されたセラミック板よりも大きくなる。遠赤外線の放射量は面積に比例するため、セラミック板５から放射される遠赤外線量は多くなり、より大きな遠赤効果をもたらすことができ、また、表面積が大きいために断熱効果も大きくなる。   Therefore, the gap 6 is set to 2 to 6 mm or less as described above, and the surface exposed to the heating chamber of the ceramic plate 5 (including the shelf 7) as shown in FIGS. 2 and 3 is about 0.5 mm. The unevenness 11 is provided. Due to the unevenness 11, the area of the ceramic plate 5 that comes into contact with the air is larger than that of the ceramic plate whose surface is processed smoothly. Since the amount of far-infrared radiation is proportional to the area, the amount of far-infrared radiation radiated from the ceramic plate 5 can be increased, resulting in a greater far-red effect, and since the surface area is large, the heat insulation effect is also increased.

実施の形態１によれば、微小の凹凸１１が形成されたセラミック板５と空隙部６の断熱層による２重の断熱効果により、エネルギーロスが少なく省エネとなり、オーブンレンジ本体１からの放熱の温度が下がり、本体１を壁に接触させた状態での設置が可能になり、火傷傷害も防止できる。さらに、加熱室２の外側近傍に設けられた電気部品の周囲温度が下がるため、高温による電気部品の劣化を防止できオーブンレンジ本体１の長寿命化となる。また、空隙部６の断熱層により、セラミック板５に蓄熱された熱が冷め難くなり、加熱室２のオーブン温度を高温に保持することができる。
また、セラミック板５の表面に形成された凹凸１１により表面積が大きくなっているので、ヒータ９の加熱によるセラミック板５からの遠赤外線の放射量が多くなり、しかも、空隙部６の断熱層により外部への放熱が抑えられるので、加熱室２内の調理物を包み込むような状態で均一に加熱調理できる。 According to the first embodiment, the double heat insulating effect of the ceramic plate 5 on which the minute irregularities 11 are formed and the heat insulating layer of the gap 6 reduces energy loss and saves energy. Can be installed in a state where the main body 1 is in contact with the wall, and burn injury can be prevented. Furthermore, since the ambient temperature of the electrical components provided in the vicinity of the outside of the heating chamber 2 is lowered, deterioration of the electrical components due to high temperatures can be prevented, and the lifetime of the microwave oven body 1 can be extended. Further, the heat insulating layer of the gap 6 makes it difficult to cool the heat stored in the ceramic plate 5, and the oven temperature of the heating chamber 2 can be kept high.
Further, since the surface area is increased by the irregularities 11 formed on the surface of the ceramic plate 5, the amount of far infrared rays emitted from the ceramic plate 5 due to the heating of the heater 9 increases, and the heat insulating layer of the gap 6 Since heat radiation to the outside is suppressed, the food in the heating chamber 2 can be cooked uniformly in a state of wrapping the cooked food.

実施の形態２．
次に、本発明の実施の形態２について図４を用いて説明する。図４は実施の形態２に係るオーブンレンジの加熱室に設けられたセラミック板の拡大断面図である。なお、本実施の形態のオーブンレンジは、セラミック板の構造を除いて、図１で説明した実施の形態１と同じである。
実施の形態２における加熱室２内のセラミック板５は、枠体３の左右側面に形成された凹部４の１段目の段部に嵌め込まれた状態になるように、外周縁部が枠体３の左右側面に接着剤１０で固着され、凹部４の２段目の段部となる内側側面とで空隙部６を形成している。このセラミック板５の加熱室内に露出する面（棚部７も含む）には、０．５ｍｍ程度の微小の凹凸１１が形成され、棚部７を除く表面には遠赤外線透過性を有するコーティング１２が施されて平滑に仕上げられている。コーテイング１２には主にリチア系等の釉薬や、抗菌塗装、親水性の強い防汚染塗装等が使用されている。 Embodiment 2. FIG.
Next, Embodiment 2 of the present invention will be described with reference to FIG. FIG. 4 is an enlarged cross-sectional view of a ceramic plate provided in the heating chamber of the microwave oven according to the second embodiment. The microwave oven of the present embodiment is the same as that of the first embodiment described with reference to FIG. 1 except for the structure of the ceramic plate.
The ceramic plate 5 in the heating chamber 2 according to the second embodiment has an outer peripheral edge portion of the frame body so that the ceramic plate 5 is fitted in the first step of the recess 4 formed on the left and right side surfaces of the frame body 3. 3 is fixed to the left and right side surfaces of the concave portion 3 with an adhesive 10, and a gap portion 6 is formed with the inner side surface which is the second stepped portion of the recess 4. On the surface (including the shelf 7) exposed in the heating chamber of the ceramic plate 5, minute irregularities 11 of about 0.5 mm are formed, and on the surface excluding the shelf 7, a coating 12 having far-infrared transmittance. Has been applied to create a smooth finish. The coating 12 is mainly made of a glaze such as Lithia, antibacterial paint, and a highly hydrophilic antifouling paint.

セラミック板５の加熱室内に露出する面には微小の凹凸１１が形成されているため、表面積が増し遠赤外線放射量は増大する。また、その表面がコーティング１２されて平滑に仕上げられているので、セラミック板５に付着した汚れ等を拭き取り易くなり、加熱室２内の清掃性が向上する。   Since the minute irregularities 11 are formed on the surface of the ceramic plate 5 exposed in the heating chamber, the surface area increases and the far-infrared radiation amount increases. Moreover, since the surface is coated 12 and finished smoothly, it becomes easy to wipe off dirt and the like adhering to the ceramic plate 5, and the cleanability in the heating chamber 2 is improved.

実施の形態３．
次に、本発明の実施の形態３について図５を用いて説明する。図５は実施の形態３に係るオーブンレンジの加熱室に設けられたセラミック板の拡大断面図である。なお、本実施の形態のオーブンレンジは、セラミック板の構造を除いて、図１で説明した実施の形態１と同じである。
実施の形態３における加熱室２内のセラミック板５は、前述したように、枠体３の左右側面に形成された凹部４の１段目の段部に固着され、凹部４の２段目の段部となる内側側面とで空隙部６を形成している。このセラミック板５の加熱室内に露出する面には０．５ｍｍ程度の微小の凹凸１１が形成されている。また、セラミック板５に形成された棚部７は、表面にコーティング１２が施され、平滑に仕上げられている。 Embodiment 3 FIG.
Next, Embodiment 3 of the present invention will be described with reference to FIG. FIG. 5 is an enlarged cross-sectional view of a ceramic plate provided in the heating chamber of the microwave oven according to the third embodiment. The microwave oven of the present embodiment is the same as that of the first embodiment described with reference to FIG. 1 except for the structure of the ceramic plate.
As described above, the ceramic plate 5 in the heating chamber 2 in the third embodiment is fixed to the first step of the recess 4 formed on the left and right side surfaces of the frame 3, and the second step of the recess 4. A gap portion 6 is formed by the inner side surface serving as a stepped portion. On the surface of the ceramic plate 5 exposed in the heating chamber, minute irregularities 11 of about 0.5 mm are formed. Further, the shelf 7 formed on the ceramic plate 5 is coated with a coating 12 on the surface and finished smooth.

実施の形態３においては、セラミック板５の加熱室内に露出する面に形成された０．５ｍｍ程度の微小の凹凸１１により、また、セラミック板５と凹部４の２段目の段部となる内側側面とで形成された空隙部６により、遠赤外線放射量が増加して加熱室２内の温度を高温に保てるという効果に加え、棚部１２の表面に施されたコーティング１２によって、調理皿出し入れ時に棚部７と調理皿８を傷つけることがなくなるという効果がある。   In the third embodiment, the inner surface of the ceramic plate 5 and the recessed portion 4 that is the second stepped portion is formed by the minute unevenness 11 of about 0.5 mm formed on the surface exposed to the heating chamber of the ceramic plate 5. In addition to the effect of increasing the amount of far-infrared radiation and maintaining the temperature in the heating chamber 2 at a high temperature by the gap 6 formed with the side surfaces, the coating 12 applied to the surface of the shelf 12 allows the cooking dish to be taken in and out. There is an effect that sometimes the shelf 7 and the cooking pan 8 are not damaged.

実施の形態４．
次に、本発明の実施の形態４について図６を用いて説明する。図６は実施の形態４に係る加熱調理器のオーブンレンジを示す正面の断面図である。なお、図１で説明した実施の形態１と同一又は相当部分には同じ符号を付し説明を省略する。
実施の形態４に係るオーブンレンジは、加熱室２内の底面と左右側面にセラミック板５が設置され、加熱室２の底面外側にヒータ９が設置されている。加熱室２内の底面に設置されたセラミック板５は、容器等が載置されるため、衝撃等に強い結晶化ガラス等の材料が用いられ、その厚さは約３ｍｍ程度である。左右側面に設置されたセラミック板５の厚さは約４ｍｍで、底面側のセラミック板５より厚く構成されている。 Embodiment 4 FIG.
Next, Embodiment 4 of the present invention will be described with reference to FIG. FIG. 6 is a front sectional view showing the microwave oven of the heating cooker according to the fourth embodiment. In addition, the same code | symbol is attached | subjected to the same or equivalent part as Embodiment 1 demonstrated in FIG. 1, and description is abbreviate | omitted.
In the microwave oven according to the fourth embodiment, the ceramic plate 5 is installed on the bottom surface and the left and right side surfaces in the heating chamber 2, and the heater 9 is installed outside the bottom surface of the heating chamber 2. The ceramic plate 5 installed on the bottom surface in the heating chamber 2 is made of a material such as crystallized glass that is resistant to impact and the like because a container or the like is placed thereon, and its thickness is about 3 mm. The thickness of the ceramic plate 5 installed on the left and right side surfaces is about 4 mm, which is thicker than the ceramic plate 5 on the bottom side.

ヒータ９が設置された底面側のセラミック板５よりも、左右側面のセラミック板５が厚く形成されているため、底面側よりも左右側面側の断熱効果が高くなる。左右側面にはヒータ９等の熱源が存在しないため、ヒータ９が存在する底面側よりも温度の立ち上がりが遅く、温度降下も早いが、左右側面側のセラミック板５を厚く構成したことで断熱効果が他の面よりも大きく作用するため、他の面との温度差が小さくなって加熱室２内の温度分布が均一になり、良好な調理状態を実現することができる。   Since the ceramic plates 5 on the left and right side surfaces are formed thicker than the ceramic plate 5 on the bottom surface side where the heater 9 is installed, the heat insulating effect on the left and right side surfaces is higher than that on the bottom surface side. Since there is no heat source such as the heater 9 on the left and right side surfaces, the temperature rise is slower and the temperature drop is faster than the bottom surface side where the heater 9 is present, but the heat insulating effect is achieved by making the ceramic plates 5 on the left and right side surfaces thicker. However, the temperature difference from the other surfaces becomes smaller, the temperature distribution in the heating chamber 2 becomes uniform, and a good cooking state can be realized.

また、ヒータ９を有する底面側のセラミック板５は薄く形成されているため、セラミック板５によるヒータ９からの放射熱の吸収が小さく、加熱室２内の温度立ち上がりを大きく悪化させることがない。   Further, since the ceramic plate 5 on the bottom surface side having the heater 9 is formed thin, absorption of radiant heat from the heater 9 by the ceramic plate 5 is small, and the temperature rise in the heating chamber 2 is not greatly deteriorated.

以上のように実施の形態４によれば、加熱室２の左右側面のセラミック板５をヒータ９が設置された底面側のセラミック板５よりも厚く構成したので、底面側での熱損失が小さく、左右側面側での断熱効果が大きくなり、加熱庫２内の温度分布が均一となり良好な調理状態を実現することができる。   As described above, according to the fourth embodiment, since the ceramic plates 5 on the left and right side surfaces of the heating chamber 2 are configured to be thicker than the ceramic plate 5 on the bottom surface side where the heater 9 is installed, the heat loss on the bottom surface side is small. The heat insulating effect on the left and right side surfaces is increased, the temperature distribution in the heating chamber 2 is uniform, and a good cooking state can be realized.

実施の形態５．
次に、本発明の実施の形態５について図７を用いて説明する。図７は実施の形態５に係る加熱調理器のオーブンレンジを示す正面の断面図である。なお、図１で説明した実施の形態１と同一又は相当部分には同じ符号を付し説明を省略する。
実施の形態５に係るオーブンレンジは、加熱室２の底面外側に、マイクロ波を発生するマグネトロン１３と、マイクロ波を加熱室２内に導く導波管１３ａと、ヒータ９とが設けられている。加熱室２内の底面に設置されたセラミック板５は、マイクロ波透過性の高い結晶化ガラス等の材料が用いられている。このセラミック板５は、マイクロ波を吸収する量が小さく、加熱の際の加熱効率を大きく悪化させることがないので、マイクロ波の給電口としても利用できる。 Embodiment 5 FIG.
Next, Embodiment 5 of the present invention will be described with reference to FIG. FIG. 7 is a front sectional view showing the microwave oven of the heating cooker according to the fifth embodiment. In addition, the same code | symbol is attached | subjected to the same or equivalent part as Embodiment 1 demonstrated in FIG. 1, and description is abbreviate | omitted.
In the microwave oven according to the fifth embodiment, a magnetron 13 that generates a microwave, a waveguide 13 a that guides the microwave into the heating chamber 2, and a heater 9 are provided outside the bottom surface of the heating chamber 2. . The ceramic plate 5 installed on the bottom surface in the heating chamber 2 is made of a material such as crystallized glass having high microwave permeability. Since the ceramic plate 5 has a small amount of absorbing microwaves and does not greatly deteriorate the heating efficiency during heating, it can also be used as a microwave feeding port.

加熱室２の左右側面に設置されたセラミック板５は、前述したように遠赤放射率の高い材料が用いられているため、ヒータ９での加熱の際には、左右側面のセラミック板５からの遠赤効果によって、調理物をムラ無く均一に加熱調理することができる。   Since the ceramic plate 5 installed on the left and right side surfaces of the heating chamber 2 is made of a material having a high far-red emissivity as described above, the ceramic plates 5 on the left and right side surfaces are heated when heated by the heater 9. Due to the far-red effect, the cooked food can be cooked uniformly without unevenness.

以上のように実施の形態５によれば、マイクロ波の給電口である底面側のセラミック板５にマイクロ波透過性の高い材料を用い、それ以外の左右側面のセラミック板５に遠赤外線放射性の高い材料を用いているので、マイクロ波加熱の加熱効率を大きく悪化させることなく、ヒータ加熱の際にはセラミック板５の遠赤効果で調理物をムラ無く均一に加熱調理することができる。   As described above, according to the fifth embodiment, a material having high microwave permeability is used for the ceramic plate 5 on the bottom surface side which is a microwave feeding port, and far infrared radiation is applied to the other ceramic plates 5 on the left and right side surfaces. Since a high material is used, the cooked food can be cooked uniformly and uniformly by the far-red effect of the ceramic plate 5 at the time of heater heating without greatly deteriorating the heating efficiency of microwave heating.
