上記した従来技術における誘導加熱調理器には、以下に示す問題がある。   The above-described induction heating cooker in the prior art has the following problems.

特許文献1に記載されたものは、本体上面前側のトッププレート枠に操作表示駆動部を備え、操作表示駆動部の上面を覆うようにゴム系材料からなる防水カバーを配置し、前記トッププレート枠の奥側で、トッププレートと接着するため、操作表示シートの接着剤はがれ部から水が浸入した場合、防水カバーに水が掛かり操作表示駆動部に水の浸入を防止するが、本体内の所定位置に水を流す構造にないため、本体内の基板部に水が掛かり故障に至ってしまう。またトッププレートとトッププレート枠の接着剤はがれ部から本体内に水が浸入した場合には、本体内の基板部に水が掛かり故障に至ってしまう。   Patent Document 1 describes that a top plate frame on the front side of the upper surface of the main body is provided with an operation display drive unit, a waterproof cover made of a rubber-based material is disposed so as to cover the upper surface of the operation display drive unit, and the top plate frame Since the adhesive is attached to the top plate at the back of the operation display sheet, if water enters from the peeled off part of the operation display sheet, the waterproof cover will be splashed with water to prevent water from entering the operation display drive part. Since there is no structure for flowing water to the position, water is applied to the substrate portion in the main body, leading to a failure. Further, when water penetrates into the main body from the adhesive peeling part of the top plate and the top plate frame, water is applied to the substrate portion in the main body, leading to a failure.

また、駆動部収納ケースに配線部品を搭載した駆動部基板を固定し、配線ケーブルを接続した後、駆動部収納ケースの底へ配線ケーブルを引き出す構造のため組立性が悪い欠点があった。   In addition, there is a drawback in that the assemblability is poor due to the structure in which the drive unit substrate on which the wiring component is mounted is fixed to the drive unit storage case and the wiring cable is connected, and then the wiring cable is drawn out to the bottom of the drive unit storage case.

また、特許文献2に記載されたものは、前辺フレームとパネル本体の嵌合凸部に防水部材を備えているが、操作パネルを具備する前辺フレームの保持部でトッププレートを保持する構成のため、前辺フレームの保持部とトッププレートのすきまにトッププレートのゴミが溜まって清掃性が悪く、水が浸入し易く、本体内の基板部に水が掛かり故障に至る欠点があった。   Moreover, although what was described in patent document 2 is equipped with the waterproof member in the fitting convex part of a front side frame and a panel main body, the structure which hold | maintains a top plate in the holding part of the front side frame which comprises an operation panel. For this reason, the dust of the top plate accumulates in the gap between the holding portion of the front frame and the top plate, and the cleaning property is poor, water easily enters, and the substrate portion in the main body is splashed with water, resulting in a failure.

また、保持部と一体に形成するリブを備えることにより、トッププレートの手前に上方に帯状の突起による段差となるため、調理鍋底の端部がのりあげて、調理鍋と誘導加熱コイルの距離が変化することで、鍋の渦電流発生が変化して、火力が変化するため、調理の使い勝手が悪い欠点がある。   In addition, by providing a rib formed integrally with the holding part, a step is formed by a band-shaped protrusion above the top plate, so that the end of the cooking pan rises and the distance between the cooking pan and the induction heating coil increases. By changing, the eddy current generation of the pan changes and the heating power changes, so there is a disadvantage that the usability of cooking is bad.

本発明は上記の欠点を解決するためになされたものであり、請求項1では、本体上面に配置されたトッププレートと、該トッププレートの周囲を囲むトッププレート枠と、複数の操作エンボス部を有し前記トッププレート枠に接着剤で貼付けられた操作シートと、前記操作エンボス部に対応してトッププレート枠に設けた開口部と、該開口部と対向して各種のスイッチを設けた操作基板と、前記開口部の下部に配置された基板ホルダと、前記基板ホルダで前記操作基板を保持して成す操作表示駆動部を備えた誘導加熱調理器において、前記開口部の下部にゴム系材料からなる防水カバーを配置し、前記防水カバーは周囲に下向きの防水案内壁と一体に形成したリブを形成し、該リブで囲まれた平面部で前記操作表示駆動部の上面を覆い、前記平面部の上下に突起し前記スイッチに対応する操作入力ボタンを設け、前記平面部の奥側に防水壁を備え、該防水壁と前記防水案内壁の間に前記平面部よりも一段低い排水溝を形成し、前記トッププレートで前記防水壁を上方から圧接するものである。   The present invention has been made to solve the above-mentioned drawbacks.
