The back face side protrusion 7 is at least provided with multiple lines of the first back face side protrusions 7a positioned on an area corresponding to the front face side protrusion 6 and with the second back face side protrusions 7b connecting each of the adjoining first back face side protrusions 7a. A covered part 3a where the electric heater 4 is covered and an exposed part 4a where the electric heater 4 is exposed are formed protruding from a reference back face BR on the part where the electric heater 4 is cast formed of the back face side. Seen from the back face side, the exposed part 4a is positioned within an area W, which is surrounded by the first back face side protrusions 7a, the second back face side protrusions 7b and the covered part 3a and where the through-hole is not formed, sectioned from the area where the hole 8 is formed.

Description

本発明は、表面側に基準表面から突出する表面側突条と、裏面側に基準裏面から突出する裏面側突条及び電熱ヒータとが一体的に鋳込み形成され、表面側突条間及び裏面側突条間に基準表面から基準裏面に貫通する貫通孔を備えた調理プレート及びその調理プレートを備えた加熱調理器に関する。   In the present invention, the surface side protrusions protruding from the reference surface on the front surface side, the back surface protrusions and the electric heater protruding from the reference back surface on the back surface side are integrally cast, and the surface side protrusions and the back surface side are integrally formed. It is related with the cooking plate provided with the through-hole penetrated from a reference | standard surface to a reference | standard back surface between protrusions, and a cooking device provided with the cooking plate.

このような調理プレートを備えた加熱調理器としては、例えば、焼き肉器、グリル鍋、ホットプレート等を例示することができる。加熱調理器は、調理プレートを表面が上側で裏面が下側となるように調理器本体に載置した状態で、電熱ヒータの発熱により加熱された調理プレートの表面に肉や野菜等の食品を載置して調理する構成とされている。   Examples of the cooking device provided with such a cooking plate include a grilled meat device, a grill pan, a hot plate, and the like. The cooking device has food such as meat and vegetables on the surface of the cooking plate heated by the heat generated by the electric heater with the cooking plate placed on the cooking device body with the top side facing up and the back side facing down. It is set as the structure which mounts and cooks.

このような加熱調理器として、例えば、特許文献１には、調理プレートの表面側に表面から上方に突出する複数列の表面側突条と、裏面側に裏面から下方に突出する電熱ヒータとが一体的に鋳込み形成され、並列する各表面側突条の間に表面から裏面に貫通する貫通孔を備えた調理プレートを、調理器本体に載置した構成が開示されている。   As such a heating cooker, for example, Patent Document 1 includes a plurality of rows of surface-side protrusions protruding upward from the surface on the surface side of the cooking plate, and an electric heater protruding downward from the back surface on the back surface side. There is disclosed a configuration in which a cooking plate having a through hole penetrating from the front surface to the back surface is placed on a cooker main body between the front surface side protrusions that are integrally cast.

この特許文献１に開示の加熱調理器では、電熱ヒータが調理プレートに一体的に鋳込み形成されているので、調理プレートの加熱効率がよく、また、表面側に突出形成された複数列の表面側突条に食品を載置して調理できるので、食品から発生した油や水等の液状物を、表面側突条の隣接間に形成された貫通孔を介して表面から裏面に流下させ、当該液状物が食品に付着することを防止できる。   In the heating cooker disclosed in Patent Document 1, since the electric heater is integrally formed on the cooking plate, the cooking plate is heated efficiently, and a plurality of rows on the surface side are formed to protrude on the surface side. Since food can be placed on the ridge and cooked, liquids such as oil and water generated from the food are allowed to flow down from the front surface to the back surface through the through holes formed between the adjacent ridges on the front surface side. The liquid material can be prevented from adhering to food.

特開平９−２９９２４７号公報Japanese Patent Laid-Open No. 9-299247

ここで、電熱ヒータを調理プレートに一体的に鋳込み形成する際には、通常、電熱ヒータを支持具等により鋳型に支持固定した状態で鋳型内に金属を流し込み、一体的に成型される。このため、調理プレートには、裏面側において、電熱ヒータが鋳込み形成された部位に、電熱ヒータが金属により被覆された被覆部と電熱ヒータが露出する露出部（鋳込み時に、支持具等により支持された部位）とが形成されることとなる（例えば、特許文献１参照）。   Here, when the electric heater is integrally cast on the cooking plate, usually, the electric heater is supported and fixed on the mold by a support or the like, and a metal is poured into the mold to be integrally molded. For this reason, the cooking plate is supported on the cooking plate on the back side by a coating portion where the electric heater is coated with metal and an exposed portion where the electric heater is exposed (supported by a support or the like at the time of casting). (See, for example, Patent Document 1).

このような電熱ヒータの露出部は、他の部位と比較して高温となる部位であり、仮に、食品の調理により発生した液状物が貫通孔を介して表面から裏面に流下して露出部に付着すると、液状物が焦げ付いて、不快な煙が発生するとともに、電熱ヒータが汚損する虞がある。   The exposed part of such an electric heater is a part that is hotter than other parts. Temporarily, the liquid material generated by cooking the food flows down from the front surface to the back surface through the through-hole and is exposed to the exposed part. If it adheres, the liquid material may burn and unpleasant smoke may be generated, and the electric heater may be soiled.

一方で、特許文献１に記載の加熱調理器では、調理プレートの表面全体の表面積に対する複数列の表面側突条の表面積は当然に小さくなっており、表面側突条に食品を載置して調理する際において、調理プレートと食品との接触面積は小さくなる。この場合、低温度或いは多量の食品を表面側突条に載置して調理しようとすると、表面側突条の温度が低下し易く、食品を良好に加熱調理することが困難或いは加熱調理に長時間を要する虞がある。従って、電熱ヒータを調理プレートに一体的に鋳込み形成していることから加熱効率の低下は抑制できているものの、調理時の温度低下を確実に防止し、食品の加熱調理を確実且つ短時間で行うことができるように改良することが望まれる。   On the other hand, in the heating cooker described in Patent Document 1, the surface area of the plurality of rows of surface-side protrusions is naturally small with respect to the surface area of the entire surface of the cooking plate, and food is placed on the surface-side protrusions. When cooking, the contact area between the cooking plate and the food is reduced. In this case, if a low temperature or a large amount of food is placed on the surface-side ridges to be cooked, the temperature of the surface-side ridges tends to decrease, making it difficult to cook the food well or to heat cooking. May take time. Therefore, since the electric heater is integrally cast on the cooking plate, the reduction in heating efficiency can be suppressed, but the temperature drop during cooking can be reliably prevented, and the food can be cooked in a short time. It would be desirable to improve so that it can be done.

本発明は、かかる実情に鑑みてなされたものであり、その目的は、少なくとも表面側突条及び電熱ヒータを一体的に鋳込み形成した調理プレートを採用した場合において、加熱効率の低下及び調理時の温度低下を確実に抑制し、しかも、調理により生じた液状物が電熱ヒータの露出部に付着することを確実に防止することができる調理プレート及びその調理プレートを備えた加熱調理器を提供することにある。   The present invention has been made in view of such circumstances, and its purpose is to reduce the heating efficiency and reduce the cooking efficiency when a cooking plate in which at least the surface-side protrusion and the electric heater are integrally cast is employed. To provide a cooking plate and a cooking device provided with the cooking plate that can reliably suppress a temperature drop and can reliably prevent a liquid material produced by cooking from adhering to an exposed portion of an electric heater. It is in.

上記目的を達成するための本発明に係る調理プレートは、表面側に基準表面から突出する表面側突条と、裏面側に基準裏面から突出する裏面側突条及び電熱ヒータとが一体的に鋳込み形成され、前記基準表面から前記基準裏面に貫通する貫通孔を備えた調理プレートであって、その特徴構成は、
複数列の前記表面側突条が、隣接間に前記貫通孔を形成した状態で配置され、
前記裏面側突条が、少なくとも前記表面側突条に対応する箇所に、隣接間に前記貫通孔を形成した状態で配置される複数列の第１裏面側突条を備えて形成され、
前記裏面側突条が、前記第１裏面側突条とは別に、前記第１裏面側突条に対して交差する箇所に、少なくとも隣接する前記第１裏面側突条同士を連結する第２裏面側突条を備えて形成され、
前記裏面側において、前記電熱ヒータが鋳込み形成された部位には、前記電熱ヒータが被覆された被覆部と、前記電熱ヒータが露出する露出部とが、前記基準裏面から突出形成され、
裏面側視で、前記露出部が、前記第１裏面側突条、前記第２裏面側突条及び前記被覆部により囲繞された領域であって且つ前記貫通孔が形成された領域から区画された貫通孔非形成領域内に配置される点にある。 In order to achieve the above object, the cooking plate according to the present invention is formed by integrally casting a surface-side protrusion protruding from the reference surface on the front surface side, and a back surface protrusion and electric heater protruding from the reference back surface on the back surface side. A cooking plate that is formed and has a through-hole penetrating from the reference surface to the reference back surface.
A plurality of rows of the surface side protrusions are arranged in a state where the through holes are formed between adjacent ones,
The back side ridge is formed with a plurality of rows of first back side ridges arranged in a state where the through hole is formed between adjacent portions at least at a position corresponding to the front side ridge,
Separately from the first back surface-side ridge, the back surface-side ridge connects at least the first back surface-side ridges adjacent to each other at a location intersecting the first back surface-side ridge. Formed with side ridges,
On the back surface side, in the portion where the electric heater is cast and formed, a covering portion covered with the electric heater and an exposed portion where the electric heater is exposed are formed protruding from the reference back surface,
When viewed from the back side, the exposed portion is a region surrounded by the first back side ridge, the second back side ridge, and the covering portion, and is partitioned from a region where the through hole is formed. It exists in the point arrange | positioned in a through-hole non-formation area | region.

本特徴構成によれば、調理プレートの裏面側に電熱ヒータが一体的に鋳込み形成され、電熱ヒータが鋳込み形成された部位は、電熱ヒータが被覆された被覆部が形成されているので、電熱ヒータにより発生した熱を、電熱ヒータを被覆する被覆部に効率よく伝熱させることができ、調理プレートの加熱効率を向上することができる。なお、電熱ヒータが鋳込み形成された部位は、主に被覆部によって形成され、電熱ヒータが露出する露出部は鋳込み形成のために必要最小限な部分にのみ形成されているので、加熱効率が低下することは最小限に抑制されている。   According to this characteristic configuration, the electric heater is integrally cast on the back side of the cooking plate, and the portion where the electric heater is cast is formed with the covering portion covered with the electric heater. The heat generated by can be efficiently transferred to the covering portion that covers the electric heater, and the heating efficiency of the cooking plate can be improved. The portion where the electric heater is cast is formed mainly by the covering portion, and the exposed portion where the electric heater is exposed is formed only in the minimum necessary portion for casting formation. Doing so is kept to a minimum.

また、調理プレートの表面側には、複数列の表面側突条が配置され、裏面側には、裏面側突条である複数列の第１裏面側突条が、少なくとも表面側突条に対応する箇所に配置されている。すなわち、少なくとも表面側突条の裏面側には第１裏面側突条が配設されているので、表面側突条の熱容量を第１裏面側突条の熱容量で補完することができ、実質的に表面側突条の熱容量を増加させることができる。これにより、複数列の表面側突条に肉や野菜等の食品を載置して加熱調理しても、表面側突条の温度低下を確実に（最小限に）抑制することができる。   In addition, a plurality of rows of front-side ridges are arranged on the front side of the cooking plate, and a plurality of rows of first back-side ridges corresponding to the back-side ridges correspond to at least the front-side ridges on the back side. It is arranged at the place to do. That is, since the first back surface-side protrusion is disposed at least on the back surface side of the surface-side protrusion, the heat capacity of the surface-side protrusion can be supplemented with the heat capacity of the first back surface-side protrusion, and substantially In addition, the heat capacity of the surface-side protrusion can be increased. Thereby, even if food, such as meat and vegetables, is placed on a plurality of rows of surface-side ridges and cooked, the temperature decrease of the surface-side ridges can be reliably suppressed (minimum).

さらに、調理プレートが、基準裏面から突出する状態で、裏面側に、複数列の第１裏面側突条と、少なくとも隣接する第１裏面側突条同士を連結し第１裏面側突条に交差する第２裏面側突条と、電熱ヒータが被覆された被覆部と、電熱ヒータが露出する露出部とを備えており、複数列の表面側突条及び複数列の第１裏面側突条のそれぞれの隣接間に、基準表面から基準裏面にまで貫通する貫通孔を備えている。従って、食品の加熱調理等により発生した液状物が貫通孔を介して裏面に流下した場合でも、基本的に、電熱ヒータの大部分は被覆部により被覆されており、液状物が被覆部に接触したとしても、煙が発生したり電熱ヒータが汚損することはない。
そして、このような構成において、裏面側視で、電熱ヒータの露出部が、第１裏面側突条、第２裏面側突条及び被覆部により囲繞された領域であって且つ貫通孔が形成された領域から区画された貫通孔非形成領域内に配置される。このため、電熱ヒータの露出部は、裏面において、貫通孔が形成された領域（基準裏面）よりも突出する第１裏面側突条、第２裏面側突条及び被覆部により囲繞されて貫通孔から区画されることとなり、露出部の周囲には貫通孔が存在しない状態となる。これにより、液状物が貫通孔を介して裏面に流下した場合でも、液状物は、一旦、第１裏面側突条、第２裏面側突条及び被覆部に接触することとなり、露出部への直接的な接触を防止することができる。従って、熱容量の増加を図ることができる第１裏面側突条及び加熱効率の増加を図ることができる被覆部を利用して、貫通孔から流下した液状物が比較的高温となる露出部に接触することを防止し、煙の発生や電熱ヒータの汚損を防止することができる。 Further, the cooking plate protrudes from the reference back surface, and a plurality of rows of first back surface protrusions and at least adjacent first back surface protrusions are connected to each other on the back surface side and intersect with the first back surface protrusions. A second back side ridge, a covering portion covered with an electric heater, and an exposed portion where the electric heater is exposed, and a plurality of rows of front side ridges and a plurality of rows of first back side ridges. Between each adjoining, a through hole penetrating from the reference surface to the reference back surface is provided. Therefore, even when the liquid material generated by cooking of food flows down to the back surface through the through-hole, basically, most of the electric heater is covered with the coating portion, and the liquid material contacts the coating portion. Even if it does, smoke does not generate | occur | produce and an electric heater does not get dirty.
In such a configuration, the exposed portion of the electric heater is a region surrounded by the first back surface side ridge, the second back surface side ridge, and the covering portion, and a through hole is formed in the back surface side view. It is arranged in a through hole non-formation region partitioned from the region. For this reason, the exposed portion of the electric heater is surrounded by the first back surface protrusion, the second back surface protrusion, and the covering portion that protrude from the region (reference back surface) where the through hole is formed on the back surface. Thus, there is no through hole around the exposed portion. Thereby, even when the liquid material flows down to the back surface through the through-hole, the liquid material once comes into contact with the first back surface-side ridge, the second back surface-side ridge, and the covering portion. Direct contact can be prevented. Therefore, the liquid material flowing down from the through hole contacts the exposed portion where the temperature is relatively high by using the first back surface protrusion that can increase the heat capacity and the covering portion that can increase the heating efficiency. It is possible to prevent the generation of smoke and the fouling of the electric heater.

よって、少なくとも表面側突条及び電熱ヒータを一体的に鋳込み形成した調理プレートを採用した場合において、加熱効率の低下及び調理時の温度低下を確実に抑制し、しかも、調理により生じた液状物が電熱ヒータの露出部に付着することを確実に防止することができる。   Therefore, in the case of adopting a cooking plate in which at least the surface-side protrusion and the electric heater are integrally formed, it is possible to reliably suppress a decrease in heating efficiency and a temperature decrease during cooking, and the liquid material generated by cooking is reduced. It can prevent reliably adhering to the exposed part of an electric heater.

本発明に係る調理プレートの更なる特徴構成は、裏面側視で、前記被覆部に面する部位以外の前記露出部の周囲が、前記貫通孔非形成領域内において、前記第１裏面側突条及び前記第２裏面側突条が形成されていない前記基準裏面により囲繞される構成である点にある。   In the cooking plate according to the present invention, the cooking plate according to the present invention is further characterized in that, when viewed from the back side, the periphery of the exposed portion other than the portion facing the covering portion is within the through-hole non-forming region. And it exists in the point which is the structure enclosed by the said reference back surface in which the said 2nd back surface side protrusion is not formed.

本特徴構成によれば、裏面側視で、露出部の周囲のうち被覆部に面する部位以外の部位が、基準裏面により囲繞される。すなわち、露出部は、被覆部及び基準裏面に隣接する状態で、貫通孔から区画された貫通孔非形成領域内に位置することとなる。ここで、被覆部及び露出部は基準裏面よりも突出形成されているとともに、第１裏面側突条及び第２裏面側突条も基準裏面から突出形成されている。
従って、断面視で、被覆部に面する部位以外の露出部の周囲と貫通孔との間は、少なくとも貫通孔側から順に、基準裏面（貫通孔）、基準裏面よりも突出する第１裏面側突条及び第２裏面側突条の何れか一方或いは両方、基準裏面、基準裏面よりも突出する露出部が位置することとなる。
これにより、貫通孔を介して裏面（基準裏面）に流下した液状物は、基準裏面（貫通孔）から第１裏面側突条及び第２裏面側突条の何れか一方或いは両方に流下し、自重によりそのまま下方に滴下することはあっても、被覆部に面する部位以外の露出部の周囲を囲繞する基準裏面に遡上（上昇）することはない。すなわち、貫通孔から流下した液状物が、露出部の周囲のうち被覆部に面する部位以外の部位から露出部に接触することを防止できる。
よって、調理により生じた液状物が電熱ヒータの露出部に付着することを、より確実に防止することができる。 According to this characteristic configuration, the portion other than the portion facing the covering portion in the periphery of the exposed portion is surrounded by the reference back surface when viewed from the back surface side. That is, the exposed portion is positioned in a through-hole non-forming region partitioned from the through-hole in a state adjacent to the covering portion and the reference back surface. Here, the covering portion and the exposed portion are formed so as to protrude from the reference back surface, and the first back surface side protrusion and the second back surface side protrusion are also formed to protrude from the reference back surface.
Accordingly, in the cross-sectional view, between the periphery of the exposed portion other than the portion facing the covering portion and the through hole, at least in order from the through hole side, the first back surface side that protrudes from the reference back surface (through hole) and the reference back surface Either one or both of the ridge and the second back side ridge, the reference back surface, and an exposed portion that protrudes from the reference back surface are located.
Thereby, the liquid material that has flowed down to the back surface (reference back surface) through the through hole flows down from the reference back surface (through hole) to one or both of the first back surface side protrusion and the second back surface protrusion. Even if it drops down as it is due to its own weight, it does not go up (up) to the reference back surface surrounding the exposed part other than the part facing the covering part. That is, it is possible to prevent the liquid material flowing down from the through hole from coming into contact with the exposed portion from a portion other than the portion facing the covering portion around the exposed portion.
Therefore, it can prevent more reliably that the liquid material produced by cooking adheres to the exposed part of an electric heater.

本発明に係る調理プレートの更なる特徴構成は、前記被覆部の前記基準裏面からの突出高さが、前記露出部の前記基準裏面からの突出高さよりも大きく形成される構成である点にある。   The further characteristic structure of the cooking plate which concerns on this invention exists in the point which is the structure by which the protrusion height from the said reference back surface of the said coating | coated part is formed larger than the protrusion height from the said reference back surface of the said exposed part. .

本特徴構成によれば、被覆部の基準裏面からの突出高さ（長さ）が、露出部の基準裏面からの突出高さ（長さ）よりも大きく形成されるので、露出部の周囲のうち被覆部に面する部位は、被覆部よりも基準裏面側に窪み形成されることとなる。
従って、断面視で、露出部の周囲において被覆部に面する部位と貫通孔との間は、少なくとも貫通孔側から順に、基準裏面（貫通孔）、基準裏面よりも突出する被覆部、基準裏面よりも突出し且つ被覆部よりも窪んだ（突出しない）露出部が位置することとなる。
これにより、貫通孔を介して裏面（基準裏面）に流下した液状物は、基準裏面（貫通孔）から被覆部に流下し、自重によりそのまま下方に滴下することはあっても、被覆部より窪んだ（突出しない）露出部に遡上（上昇）することはない。すなわち、貫通孔から流下した液状物が、露出部の周囲のうち被覆部に面する部位から露出部に接触することを防止できる。
特に、本特徴構成に加えて、上述の特徴構成で説明した、裏面側視で、露出部の周囲のうち被覆部に面する部位以外の部位が基準裏面により囲繞される構成を採用すると、貫通孔を介して流下した液状物が露出部に接触することを、露出部の周囲のうち全ての周囲について防止することができるので好ましい。 According to this characteristic configuration, the protruding height (length) of the covering portion from the reference back surface is formed larger than the protruding height (length) of the exposed portion from the reference back surface. Of these, the portion facing the covering portion is formed to be recessed toward the reference back side with respect to the covering portion.
Therefore, in a cross-sectional view, between the portion facing the covering portion around the exposed portion and the through hole, at least in order from the through hole side, the reference back surface (through hole), the covering portion protruding from the reference back surface, the reference back surface The exposed portion that protrudes more than the covering portion and is recessed (not protruding) than the covering portion is located.
As a result, the liquid material that has flowed down to the back surface (reference back surface) through the through-hole flows down from the reference back surface (through-hole) to the coating portion, and may drop downward due to its own weight, but is depressed from the coating portion. It does not run up (rise) to the exposed part (which does not protrude). That is, it is possible to prevent the liquid material flowing down from the through hole from coming into contact with the exposed portion from the portion facing the covering portion in the periphery of the exposed portion.
In particular, in addition to this feature configuration, when the configuration described in the above-described feature configuration, where a portion other than the portion facing the covering portion of the periphery of the exposed portion is surrounded by the reference back surface, the penetration is adopted. It is preferable that the liquid material flowing down through the holes can be prevented from coming into contact with the exposed portion for all the surroundings of the exposed portion.

本発明に係る調理プレートの更なる特徴構成は、前記表面側突条が、前記調理プレートの長手方向に沿って配設され、前記第１裏面側突条が、前記調理プレートの長手方向に沿って配設された点にある。   In a further characteristic configuration of the cooking plate according to the present invention, the front surface-side protrusion is disposed along the longitudinal direction of the cooking plate, and the first back surface-side protrusion is along the longitudinal direction of the cooking plate. It is in the point arranged.

本特徴構成によれば、表面側突条及び第１裏面側突条を調理プレートの長手方向に沿って配設するので、調理プレートを表面側及び裏面側の両方で最適に補強することができ、電熱ヒータによる加熱や外部からの力による変形や破損を良好に防止することができる。   According to this characteristic configuration, the front side protrusion and the first back side protrusion are arranged along the longitudinal direction of the cooking plate, so that the cooking plate can be optimally reinforced on both the front side and the back side. Further, it is possible to satisfactorily prevent deformation and breakage due to heating by an electric heater or external force.

本発明に係る調理プレートの更なる特徴構成は、前記表面側突条が、前記調理プレートの端部に亘って配設され、前記第１裏面側突条が、前記調理プレートの端部に亘って配設された点にある。   In a further characteristic configuration of the cooking plate according to the present invention, the front side ridge is disposed over the end of the cooking plate, and the first back side ridge extends over the end of the cooking plate. It is in the point arranged.

本特徴構成によれば、表面側突条及び第１裏面側突条を調理プレートの端部に亘って配設するので、表面側において食品を載置するスペースを十分に確保しながら、調理プレートを表面側及び裏面側の両方で最適に補強することができ、電熱ヒータによる加熱や外部からの力による変形や破損を良好に防止することができる。   According to this characteristic configuration, the front surface side ridge and the first back surface side ridge are disposed over the end of the cooking plate, so that a sufficient space for food is placed on the front surface side while ensuring sufficient space for the food. Can be optimally reinforced on both the front surface side and the back surface side, and deformation or breakage due to heating by an electric heater or external force can be satisfactorily prevented.

上記目的を達成するための本発明に係る加熱調理器の特徴構成は、上記特徴構成の何れかを備えた調理プレートが、調理器本体上に着脱自在に載置されてなる点にある。   The characteristic configuration of the heating cooker according to the present invention for achieving the above object is that a cooking plate having any one of the above-described characteristic configurations is detachably mounted on the cooker body.

本特徴構成によれば、上記調理プレートを調理器本体上に載置して、調理プレートの表面に突出形成された複数列の表面側突条に食品を載置して加熱調理することができる。
これにより、少なくとも表面側突条及び電熱ヒータを一体的に鋳込み形成した調理プレートを採用して、加熱効率の低下及び調理時の温度低下を確実に抑制し、しかも、調理により生じた液状物が電熱ヒータの露出部に付着することを確実に防止することができる加熱調理器を得ることができた。 According to this characteristic configuration, the cooking plate can be placed on the cooker body, and food can be placed on a plurality of rows of protrusions formed on the surface of the cooking plate to be cooked by heating. .
Accordingly, a cooking plate in which at least the surface-side protrusion and the electric heater are integrally cast is adopted to reliably suppress a decrease in heating efficiency and a temperature decrease during cooking, and the liquid material generated by cooking is reduced.

ホットプレートＨの各部の構成について説明する。
図１及び図２に示すように、調理器本体１は、平面視で概略矩形（四隅が曲線で形成され、丸みを帯びた長方形状）に形成され、断面視で深皿状に形成された耐熱性の樹脂部材により構成されている。調理器本体１の下面には、上下方向に連通する下面開口部（図示せず）が形成され、机などへ載置するための合計４個の載置脚（図示せず）が当該下面開口部の周囲に配設されている。 The configuration of each part of the hot plate H will be described.
As shown in FIGS. 1 and 2, the cooker body 1 is formed in a substantially rectangular shape (four corners are curved and rounded) in a plan view, and in a deep dish shape in a cross-sectional view. It is comprised by the heat resistant resin member. A lower surface opening (not shown) communicating in the vertical direction is formed on the lower surface of the cooker body 1, and a total of four mounting legs (not shown) for mounting on a desk or the like are provided on the lower surface opening. It is arrange | positioned around the part.

調理器本体１の外縁部には、環状に形成された外縁壁部１Ａが上方に突出形成され、外縁壁部１Ａの内周面１ａには、水受け皿２を載置するための板状支持部１Ｂが、内方側に突出する状態で複数立設されている。板状支持部１Ｂは、調理器本体１の四隅のうちの各隅部にそれぞれ一対配設されている（本実施形態では、８個）。   An outer edge wall portion 1A formed in an annular shape protrudes upward from the outer edge portion of the cooker body 1, and a plate-like support for placing the water tray 2 on the inner peripheral surface 1a of the outer edge wall portion 1A. A plurality of portions 1B are erected in a state of protruding inward. A pair of plate-like support portions 1 </ b> B is disposed at each corner portion of the four corners of the cooker body 1 (eight in the present embodiment).

A pair of handle accommodating portions 1C. The handle accommodating portion 1C is formed to be depressed downward from the upper surface of the outer edge wall portion 1A.

水受け皿２は、平面視で調理器本体１よりも全体的に小さな概略矩形（四隅が曲線で形成され、丸みを帯びた長方形状）に形成され、断面視で皿状に形成された金属部材により構成されている。水受け皿２は、外縁部に全周に亘って水平方向に突出形成される鍔部２Ａと、鍔部２Ａの内方側に形成され下方に膨出する下方膨出部２Ｂとを備えており、下方膨出部２Ｂ内に水を貯留可能に構成されている。水受け皿２は、下方膨出部２Ｂの外面を複数の板状支持部１Ｂの内側面に当接させた状態で、鍔部２Ａを複数の板状支持部１Ｂの上部に載置することにより、調理器本体１内に水受け皿２を安定して載置でき、水受け皿２を水平に維持できるように構成されている。従って、下方膨出部２Ｂ内に貯留された水が、水受け皿２から不用意に漏出することがないように構成されている。   The water tray 2 is a metal member that is formed into a generally rectangular shape (four corners are curved and rounded) that is smaller than the cooker body 1 in plan view, and is formed in a dish shape in cross section. It is comprised by. The water tray 2 includes a flange portion 2A that protrudes in the horizontal direction over the entire periphery of the outer edge portion, and a lower bulge portion 2B that is formed on the inner side of the flange portion 2A and bulges downward. In the downward bulging portion 2B, water can be stored. The water tray 2 is configured by placing the flange portion 2A on top of the plurality of plate-like support portions 1B in a state where the outer surface of the downward bulging portion 2B is in contact with the inner surface of the plurality of plate-like support portions 1B. The water tray 2 can be stably placed in the cooker body 1 and the water tray 2 can be maintained horizontally. Therefore, the water stored in the downward bulging portion 2B is configured not to inadvertently leak from the water tray 2.

図１〜図５に示すように、調理プレート３は、平面視で調理器本体１よりも全体的に若干小さな概略矩形（四隅が曲線で形成され、丸みを帯びた長方形状）に形成された、平板状の金属部材により構成されている。   As shown in FIGS. 1 to 5, the cooking plate 3 is formed in a generally rectangular shape (four corners are curved and rounded rectangular shape) slightly smaller than the cooker body 1 in plan view. It is comprised by the flat metal member.

調理プレート３は、表面側に基準表面ＢＡから突出する表面側突条６と、裏面側に基準裏面ＢＲから突出する裏面側突条７及び電熱ヒータ４と、が一体的に鋳込み形成されている。なお、基準表面ＢＡは、表面側突条６より凹んだ面であればよく、表面側突条６からの凹み代（凹み高さ）の異なる複数の面として設定することもできる。当該凹み代（凹み高さ）の異なる複数の面を設定した場合には、基準表面ＢＡは第１基準表面、第２基準表面等、複数の基準表面として設定されることとなる。また、基準裏面ＢＲについても同様に、裏面側突条７及び電熱ヒータ４より凹んだ面であればよく、裏面側突条７及び電熱ヒータ４からの凹み代（凹み高さ）の異なる複数の面として設定することもできる。当該凹み代（凹み高さ）の異なる複数の面を設定した場合には、基準裏面ＢＲは第１基準裏面、第２基準裏面等、複数の基準裏面として設定されることとなる。
電熱ヒータ４を調理プレート３に一体的に鋳込み形成する際には、電熱ヒータ４を支持具等（図示せず）により鋳型（図示せず）に支持固定した状態で鋳型内に金属を流し込み、一体的に成型される。このため、図４〜図６に示すように、調理プレート３には、裏面側において、電熱ヒータ４が鋳込み形成された部位に、電熱ヒータ４が金属により被覆された被覆部３ａと電熱ヒータが露出する露出部４ａ（鋳込み時に、支持具等により支持された部位）とが形成されている。電熱ヒータ４が鋳込み形成された部位は、主に被覆部３ａによって形成され、露出部４ａは鋳込み形成のために必要最小限な部分にのみ形成されているので、電熱ヒータ４により発生した熱を、電熱ヒータ４を被覆する被覆部３ａに効率よく伝熱させ調理プレート３の加熱効率を向上することができ、しかも、露出部４ａの存在による加熱効率の低下は最小限に抑制されている。 The cooking plate 3 is formed by integrally casting a surface side ridge 6 protruding from the reference surface BA on the surface side and a back surface ridge 7 and electric heater 4 protruding from the reference back surface BR on the back side. . The reference surface BA only needs to be a surface that is recessed from the surface-side protrusion 6, and can be set as a plurality of surfaces having different recesses (indentation heights) from the surface-side protrusion 6. When a plurality of surfaces with different dent allowances (dent heights) are set, the reference surface BA is set as a plurality of reference surfaces such as a first reference surface and a second reference surface. Similarly, the reference back surface BR may be a surface that is recessed from the back surface side ridge 7 and the electric heater 4, and a plurality of dents (indentation heights) different from the back surface side ridge 7 and the electric heater 4 are different. It can also be set as a surface.

An exposed portion 4a (a portion supported by a support or the like at the time of casting) is formed. The portion where the electric heater 4 is cast is formed mainly by the covering portion 3a, and the exposed portion 4a is formed only at the minimum necessary portion for casting, so that the heat generated by the electric heater 4 is generated. Further, heat can be efficiently transferred to the covering portion 3a covering the electric heater 4, and the heating efficiency of the cooking plate 3 can be improved. In addition, a decrease in heating efficiency due to the presence of the exposed portion 4a is suppressed to a minimum.

The region is surrounded by the portion 3a and is disposed in a through-hole non-forming region W that is partitioned from the region where the through-hole 8 is formed.

例を挙げて説明すると、図４〜図７に示すように、例えば、露出部４ａとしての第１露出部４ａ１の周囲は、次の順序で囲繞された貫通孔非形成領域Ｗ内に配置されている。
具体的には、第１露出部４ａ１の周囲には、例えば右回り（図６において、白丸を出発点として、実線の矢印で示す軌跡）で説明すると、被覆部３ａ、第１裏面側突条７ａ、第２裏面側突条７ｂ、第１裏面側突条７ａ、被覆部３ａ、第１裏面側突条７ａ、第２裏面側突条７ｂ、第１裏面側突条７ａ、最初に記載の被覆部３ａが記載順に配設される。これら第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａは、基準裏面ＢＲから下方に突出形成されている。従って、第１露出部４ａ１は、これら第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａにより囲繞された領域内に位置し、一方で、貫通孔８は、これら第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａにより囲繞された領域の外側に位置することとなるため、第１露出部４ａ１は、貫通孔非形成領域Ｗ内に位置するのである。 For example, as shown in FIGS. 4 to 7, for example, the periphery of the first exposed portion 4 a 1 as the exposed portion 4 a is arranged in the through-hole non-forming region W surrounded in the following order. ing.
Specifically, for example, in the clockwise direction (in FIG. 6, a white circle as a starting point and a locus indicated by a solid line arrow) around the first exposed portion 4a1, the covering portion 3a, the first back-side protrusion 7a, second back side ridge 7b, first back side ridge 7a, covering portion 3a, first back side ridge 7a, second back side ridge 7b, first back side ridge 7a, first described The covering portion 3a is arranged in the order of description. The first back surface protrusion 7a, the second back surface protrusion 7b, and the covering portion 3a are formed so as to protrude downward from the reference back surface BR. Accordingly, the first exposed portion 4a1 is located in a region surrounded by the first back surface-side ridge 7a, the second back surface-side ridge 7b, and the covering portion 3a, while the through hole 8 has the first through-hole 8 formed therein. Since the first exposed portion 4a1 is located in the through hole non-formation region W because it is located outside the region surrounded by the back surface side ridge 7a, the second back surface side ridge 7b, and the covering portion 3a. is there.

また、他の例を挙げて説明すると、図４〜図６、図８に示すように、例えば、露出部４ａとしての第２露出部４ａ２の周囲は、次の順序で囲繞された貫通孔非形成領域Ｗ内に配置されている。
具体的には、第２露出部４ａ２の周囲には、例えば右回り（図６において、白丸を出発点として、破線の矢印で示す軌跡）で説明すると、被覆部３ａ、第１裏面側突条７ａ、第２裏面側突条７ｂ、第１裏面側突条７ａ、第２裏面側突条７ｂ、第１裏面側突条７ａ、被覆部３ａ、第１裏面側突条７ａ、第２裏面側突条７ｂ、第１裏面側突条７ａ、第２裏面側突条７ｂ、第１裏面側突条７ａ、第２裏面側突条７ｂ、第１裏面側突条７ａ、最初に記載の被覆部３ａが記載順に配設される。これら第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａは、基準裏面ＢＲから下方に突出形成されている。従って、第２露出部４ａ２は、これら第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａにより囲繞された領域内に位置し、一方で、貫通孔８は、これら第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａにより囲繞された領域の外側に位置することとなるため、第２露出部４ａ２は、貫通孔非形成領域Ｗ内に位置するのである。 In addition, as described with reference to other examples, as shown in FIGS. 4 to 6 and 8, for example, the periphery of the second exposed portion 4a2 as the exposed portion 4a is surrounded by a through-hole that is surrounded in the following order. It is arranged in the formation region W.
Specifically, for example, in a clockwise direction around the second exposed portion 4a2 (in FIG. 6, a white circle as a starting point and a locus indicated by a dashed arrow), the covering portion 3a, the first back side protrusion 7a, 2nd back surface side protrusion 7b, 1st back surface side protrusion 7a, 2nd back surface side protrusion 7b, 1st back surface side protrusion 7a, coating | coated part 3a, 1st back surface side protrusion 7a, 2nd back surface side Ridge 7b, first back side ridge 7a, second back side ridge 7b, first back side ridge 7a, second back side ridge 7b, first back side ridge 7a, first covering portion 3a are arranged in the order of description. The first back surface protrusion 7a, the second back surface protrusion 7b, and the covering portion 3a are formed so as to protrude downward from the reference back surface BR. Accordingly, the second exposed portion 4a2 is located in a region surrounded by the first back surface-side ridge 7a, the second back surface-side ridge 7b, and the covering portion 3a, while the through hole 8 has the first through-hole 8 formed therein. Since the second exposed portion 4a2 is located in the through hole non-formation region W because the second exposed portion 4a2 is located outside the region surrounded by the back surface side ridge 7a, the second back surface ridge 7b, and the covering portion 3a. is there.

なお、上記では露出部４ａを代表して第１露出部４ａ１及び第２露出部４ａ２の囲繞状態について説明したが、露出部４ａが、第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａにより囲繞されて、貫通孔８が形成された領域と区画される構成であれば、その他の囲繞状態で構成してもよい。   In addition, although the surrounding state of the 1st exposed part 4a1 and the 2nd exposed part 4a2 was demonstrated on behalf of the exposed part 4a above, the exposed part 4a is the 1st back surface side protrusion 7a, the 2nd back surface side protrusion 7b. As long as it is configured to be surrounded by the covering portion 3a and partitioned from the region in which the through hole 8 is formed, it may be configured in other surrounding states.

また、調理プレート３の裏面側には、裏面側視で、被覆部３ａに面する部位以外の露出部４ａの周囲が、貫通孔非形成領域Ｗ内において、第１裏面側突条７ａ及び第２裏面側突条７ｂが形成されていない基準裏面ＢＲにより囲繞されている。すなわち、裏面側視で、露出部４ａの周囲のうち被覆部３ａに面する部位以外の部位が、基準裏面ＢＲにより囲繞されるため、露出部４ａは、被覆部３ａ及び基準裏面ＢＲに隣接する状態で、貫通孔８から区画された貫通孔非形成領域Ｗ内に位置している。なお、図３〜図６に示すように、調理プレート３において電熱ヒータ４が鋳込み形成された部位、表面側突条６、第１裏面側突条７ａ及び第２裏面側突条７ｂが形成された部位には、貫通孔８が形成されていない。   Further, on the back surface side of the cooking plate 3, the periphery of the exposed portion 4 a other than the portion facing the covering portion 3 a in the back surface side view is within the through-hole non-forming region W, and the first back surface-side protrusion 7 a and the first 2 Surrounded by a reference back surface BR on which no back surface-side protrusion 7b is formed. That is, in the back side view, since the portion other than the portion facing the covering portion 3a in the periphery of the exposed portion 4a is surrounded by the reference back surface BR, the exposed portion 4a is adjacent to the covering portion 3a and the reference back surface BR. In the state, it is located in the through-hole non-forming region W partitioned from the through-hole 8. As shown in FIGS. 3 to 6, the portion where the electric heater 4 is cast and formed on the cooking plate 3, the front side protrusion 6, the first back surface protrusion 7 a and the second back surface protrusion 7 b are formed. The through hole 8 is not formed in the part.

ここで、図７及び図８に示すように、第１裏面側突条７ａ、第２裏面側突条７ｂ、被覆部３ａ及び露出部４ａの基準裏面ＢＲからの突出高さはそれぞれ、第１裏面側突条７ａの突出高さＬ１、第２裏面側突条７ｂの突出高さＬ２、被覆部３ａの突出高さＬ３、露出部４ａの突出高さＬ４とされている。本実施形態では、これら突出高さＬ１〜Ｌ４の高さ（長さ）関係は、Ｌ１＝Ｌ２＜Ｌ４＜Ｌ３に設定されている。なお、図示しないが、表面側突条６の基準表面ＢＡからの突出高さは、第１裏面側突条７ａの突出高さＬ１及び第２裏面側突条７ｂの突出高さＬ２と同等の高さに設定されている。   Here, as shown in FIGS. 7 and 8, the protrusion height from the reference back surface BR of the first back surface-side protrusion 7a, the second back surface-side protrusion 7b, the covering portion 3a, and the exposed portion 4a is 1st respectively. The protrusion height L1 of the back surface-side ridge 7a, the protrusion height L2 of the second back surface-side ridge 7b, the protrusion height L3 of the covering portion 3a, and the protrusion height L4 of the exposed portion 4a. In the present embodiment, the height (length) relationship between the protruding heights L1 to L4 is set to L1 = L2 <L4 <L3. In addition, although not shown in figure, the protrusion height from the reference | standard surface BA of the surface side protrusion 6 is equivalent to the protrusion height L1 of the 1st back surface protrusion 7a, and the protrusion height L2 of the 2nd back surface protrusion 7b. It is set to height.

従って、露出部４ａの周囲のうち被覆部３ａに面する部位以外の部位は、基準裏面ＢＲから突出高さＬ４だけ突出した状態で、基準裏面ＢＲに隣接することとなる。すなわち、図４〜図６、図７（ａ）及び図８（ｂ）に示すように、断面視で、被覆部３ａに面する部位以外の露出部４ａ（図では、第１露出部４ａ１及び第２露出部４ａ２）の周囲と貫通孔８との間は、少なくとも貫通孔８側から順に、基準裏面ＢＲ（貫通孔８）、基準裏面ＢＲよりも突出する第１裏面側突条７ａ又は第２裏面側突条７ｂ、基準裏面ＢＲ、基準裏面ＢＲよりも突出する露出部４ａが位置することとなる。   Accordingly, a portion of the periphery of the exposed portion 4a other than the portion facing the covering portion 3a is adjacent to the reference back surface BR in a state of protruding from the reference back surface BR by the protrusion height L4. That is, as shown in FIG. 4 to FIG. 6, FIG. 7A and FIG. 8B, the exposed portion 4 a (in the drawing, the first exposed portion 4 a 1 and the portion other than the portion facing the covering portion 3 a in a cross-sectional view). Between the periphery of the second exposed portion 4a2) and the through hole 8, the first back surface protrusion 7a or the first back surface protrusion 7a protruding from the reference back surface BR (through hole 8) and the reference back surface BR in order from at least the through hole 8 side. The exposed part 4a which protrudes rather than 2 back surface side protrusion 7b, reference | standard back surface BR, and reference | standard back surface BR will be located.

また、被覆部３ａの基準裏面ＢＲからの突出高さＬ３が、露出部４ａの基準裏面ＢＲからの突出高さＬ４よりも大きく形成されるので、露出部４ａの周囲のうち被覆部３ａに面する部位は、被覆部３ａよりも基準裏面ＢＲ側に窪み形成されることとなる。すなわち、図４〜図６、図７（ｂ）及び図８（ａ）に示すように、断面視で、露出部４ａ（図では、第１露出部４ａ１及び第２露出部４ａ２）の周囲において被覆部３ａに面する部位と貫通孔８との間は、少なくとも貫通孔８側から順に、基準裏面ＢＲ（貫通孔８）、基準裏面ＢＲよりも突出する被覆部３ａ、基準裏面ＢＲよりも突出し且つ被覆部３ａよりも窪んだ（突出しない）露出部４ａが位置することとなる。   Further, since the protruding height L3 of the covering portion 3a from the reference back surface BR is formed larger than the protruding height L4 of the exposed portion 4a from the reference back surface BR, the surface of the covering portion 3a around the exposed portion 4a faces the covering portion 3a. The portion to be formed is formed to be recessed toward the reference back surface BR side with respect to the covering portion 3a. That is, as shown in FIGS. 4 to 6, 7 (b) and 8 (a), in the cross-sectional view, around the exposed portion 4 a (the first exposed portion 4 a 1 and the second exposed portion 4 a 2 in the drawing). Between the part facing the covering portion 3a and the through hole 8, the reference back surface BR (through hole 8), the covering portion 3a protruding from the reference back surface BR, and the reference back surface BR protrude at least from the through hole 8 side. In addition, the exposed portion 4a that is recessed (not protruding) from the covering portion 3a is located.

次に、上記のように構成されるホットプレートＨを使用して肉や野菜等の食品の加熱調理をした際に、主として加熱調理により食品から発生した油や水等の液状物が、貫通孔８を介して調理プレート３の基準表面ＢＡから基準裏面ＢＲに流下する流れについて、概略的に説明する。   Next, when the food such as meat and vegetables is cooked using the hot plate H configured as described above, liquids such as oil and water generated mainly from the food by the cooking are through holes. The flow that flows down from the reference surface BA of the cooking plate 3 to the reference back surface BR through 8 will be described schematically.

まず、図１及び図２に示すように、水受け皿２を調理器本体１内に載置し、水受け皿２内に所定量の水を貯留した後、調理プレート３に取り付けられた一対のハンドル部５を調理器本体１における一対のハンドル収容部１Ｃに載置・収容して、調理器本体１に水受け皿２及び調理プレート３を一体的に装着する。そして、プラグ受け部３０の電源プラグ３２を装着して温度調節ダイヤル３３を操作し、電源から所定量の電力を電熱ヒータ４に供給し当該電熱ヒータ４により調理プレート３を所望の温度に加熱させる。
その後、所望の温度に加熱された調理プレート３の複数列の表面側突条６上に、食品を載置して加熱調理する。 First, as shown in FIG. 1 and FIG. 2, a pair of handles attached to the cooking plate 3 after the water tray 2 is placed in the cooker body 1 and a predetermined amount of water is stored in the water tray 2. The portion 5 is placed and accommodated in a pair of handle accommodating portions 1 </ b> C in the cooker main body 1, and the water tray 2 and the cooking plate 3 are integrally attached to the cooker main body 1. Then, the power plug 32 of the plug receiving portion 30 is attached and the temperature adjustment dial 33 is operated to supply a predetermined amount of power from the power source to the electric heater 4 and the cooking plate 3 is heated to a desired temperature by the electric heater 4. .
Thereafter, food is placed on the plurality of surface side protrusions 6 of the cooking plate 3 heated to a desired temperature and cooked by heating.

この加熱調理の際、表面側突条６及びその近傍の温度が低下しても、調理プレート３の裏面側において表面側突条６に対応する箇所には第１裏面側突条７ａが形成されているので、表面側突条６の熱容量を第１裏面側突条７ａの熱容量で補完することができ、表面側突条６の熱容量を実質的に増加させることができる。これにより、複数列の表面側突条６に食品を載置して加熱調理しても、表面側突条６の温度低下を確実に（最小限に）抑制することができる。   Even when the temperature of the front surface side ridge 6 and the vicinity thereof is reduced during the cooking, the first back surface ridge 7 a is formed at a position corresponding to the front surface side ridge 6 on the back surface side of the cooking plate 3. Therefore, the heat capacity of the front side protrusion 6 can be supplemented with the heat capacity of the first back surface protrusion 7a, and the heat capacity of the front surface protrusion 6 can be substantially increased. Thereby, even if food is placed on the plurality of rows of surface-side ridges 6 and cooked, the temperature drop of the surface-side ridges 6 can be reliably (minimally) suppressed.

一方、調理プレート３の表面側突条６に食品を載置して加熱調理を行った際に発生した油や水等の液状物は、貫通孔８を介して基準表面ＢＡ側から基準裏面ＢＲ側に流下するが、基本的に、電熱ヒータ４の大部分は被覆部３ａにより被覆されており、液状物が被覆部３ａに接触したとしても、煙が発生したり電熱ヒータ４が汚損することはない。   On the other hand, liquid substances such as oil and water generated when food is placed on the front surface protrusion 6 of the cooking plate 3 and cooked are transferred from the reference surface BA side through the through hole 8 to the reference back surface BR. Basically, most of the electric heater 4 is covered with the covering portion 3a, and even if a liquid material comes into contact with the covering portion 3a, smoke is generated or the electric heater 4 is soiled. There is no.

また、電熱ヒータ４の露出部４ａは、裏面において、貫通孔８が形成された領域（基準裏面ＢＲ）よりも突出する第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａにより囲繞されて貫通孔８から区画される。そのため、貫通孔８を介して基準裏面ＢＲ側に流下した液状物は、一旦、第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａに接触することとなり、露出部４ａへの直接的な接触を防止することができる。   Further, the exposed portion 4a of the electric heater 4 has a first back side protrusion 7a, a second back side protrusion 7b, and a covering portion 3a that protrude beyond the region (reference back surface BR) where the through hole 8 is formed on the back surface. And is partitioned from the through hole 8. Therefore, the liquid material flowing down to the reference back surface BR side through the through-hole 8 once comes into contact with the first back surface side ridge 7a, the second back surface side ridge 7b, and the covering portion 3a, to the exposed portion 4a. Can prevent direct contact.

さらに、断面視で、被覆部３ａに面する部位以外の露出部４ａの周囲と貫通孔８との間は、少なくとも貫通孔８側から順に、基準裏面ＢＲ（貫通孔８）、基準裏面ＢＲよりも突出する第１裏面側突条７ａ及び第２裏面側突条７ｂの何れか一方或いは両方、基準裏面ＢＲ、基準裏面ＢＲよりも突出する露出部４ａが位置することとなる。そのため、貫通孔８を介して基準裏面ＢＲに流下した液状物は、第１裏面側突条７ａ及び第２裏面側突条７ｂの何れか一方或いは両方に流下し、自重によりそのまま下方に滴下することはあっても、被覆部３ａに面する部位以外の露出部４ａの周囲を囲繞する基準裏面ＢＲに遡上（上昇）することはない。すなわち、貫通孔８から流下した液状物が、露出部４ａの周囲のうち被覆部３ａに面する部位以外の部位から露出部４ａに接触することを防止できる。   Furthermore, in the cross-sectional view, the space between the periphery of the exposed portion 4a other than the portion facing the covering portion 3a and the through hole 8 is at least from the reference back surface BR (through hole 8) and the reference back surface BR in order from the through hole 8 side. In addition, one or both of the first rear surface side ridge 7a and the second rear surface side ridge 7b that protrude, and the exposed portion 4a that protrudes from the reference back surface BR and the reference back surface BR are located. Therefore, the liquid material that has flowed down to the reference back surface BR through the through-hole 8 flows down to one or both of the first back surface side ridge 7a and the second back surface side ridge 7b, and drops down as it is by its own weight. Even if this is the case, the reference back surface BR that surrounds the periphery of the exposed portion 4a other than the portion facing the covering portion 3a does not rise (rise). That is, the liquid material flowing down from the through hole 8 can be prevented from coming into contact with the exposed portion 4a from a portion other than the portion facing the covering portion 3a in the periphery of the exposed portion 4a.

加えて、断面視で、露出部４ａの周囲において被覆部３ａに面する部位と貫通孔８との間は、少なくとも貫通孔８側から順に、基準裏面ＢＲ（貫通孔８）、基準裏面ＢＲよりも突出する被覆部３ａ、基準裏面ＢＲよりも突出し且つ被覆部３ａよりも窪んだ（突出しない）露出部４ａが位置する。そのため、貫通孔８を介して基準裏面ＢＲに流下した液状物は、基準裏面ＢＲ（貫通孔８）、被覆部３ａに流下し、自重によりそのまま下方に滴下することはあっても、被覆部３ａより窪んだ（突出しない）露出部４ａに遡上（上昇）することはない。すなわち、貫通孔８から流下した液状物が、露出部４ａの周囲のうち被覆部３ａに面する部位から露出部４ａに接触することを防止できる。   In addition, in a cross-sectional view, between the portion facing the covering portion 3a around the exposed portion 4a and the through hole 8, at least in order from the through hole 8 side, from the reference back surface BR (through hole 8) and the reference back surface BR. Further, the exposed covering portion 3a and the exposed portion 4a that protrudes from the reference back surface BR and is depressed (not protruding) from the covering portion 3a are located. For this reason, the liquid material that has flowed down to the reference back surface BR through the through hole 8 flows down to the reference back surface BR (through hole 8) and the covering portion 3a, and may be dropped as it is by its own weight. The exposed portion 4a that is more depressed (not protruding) does not rise (rise). That is, it is possible to prevent the liquid material flowing down from the through hole 8 from coming into contact with the exposed portion 4a from the portion facing the covering portion 3a in the periphery of the exposed portion 4a.

すなわち、貫通孔８を介して流下した液状物が露出部４ａに接触することを、露出部４ａの周囲のうち全ての周囲について防止することができる。   That is, it is possible to prevent the liquid material flowing down through the through-hole 8 from coming into contact with the exposed portion 4a for all the surroundings of the exposed portion 4a.

なお、第１裏面側突条７ａ、第２裏面側突条７ｂ及び被覆部３ａに流下して下方に滴下した液状物は、下方に配設された水受け皿２内に滴下して、水受け皿２内に貯留された水により冷却されるとともに、水受け皿２の外部への漏出が防止されている。また、表面側で肉等を載置して調理を行った際に発生した肉汁等の油が調理プレート３の周囲から滴下することは、表面側外縁凸部９によって防止されている。   In addition, the liquid substance which flowed down to the 1st back surface side protrusion 7a, the 2nd back surface side protrusion 7b, and the coating | coated part 3a and was dripped below is dripped in the water tray 2 arrange | positioned below, and a water tray While being cooled by the water stored in 2, leakage to the outside of the water tray 2 is prevented. Further, the surface side outer edge convex portion 9 prevents oil such as gravy generated when meat is placed on the surface side and cooking is performed from the periphery of the cooking plate 3.

よって、少なくとも表面側突条６及び電熱ヒータ４を一体的に鋳込み形成した調理プレート３を採用した場合において、加熱効率の低下及び調理時の温度低下を確実に抑制し、しかも、調理により生じた液状物が電熱ヒータ４の露出部４ａに付着することを確実に防止することができた。   Therefore, in the case of adopting the cooking plate 3 in which at least the surface-side protrusion 6 and the electric heater 4 are integrally cast and formed, it is possible to reliably suppress a decrease in heating efficiency and a decrease in temperature during cooking, and it is caused by cooking. It was possible to reliably prevent the liquid material from adhering to the exposed portion 4a of the electric heater 4.
