Description

この発明は、グリルを備え誘導加熱により加熱する加熱調理器に関する。   The present invention relates to a cooking device that includes a grill and heats by induction heating.

従来の加熱調理器は、本体の略中央にグリルを配設し、グリルを挟んで略対称に複数の上方加熱装置と制御装置と冷却ファンと吸気口と排気口を配設することで、左右の冷却バランスを取り効率的な冷却構成としている（例えば、特許文献１参照）。   A conventional heating cooker has a grill disposed substantially in the center of the main body, and a plurality of upper heating devices, a control device, a cooling fan, an intake port, and an exhaust port disposed substantially symmetrically across the grill. Therefore, an efficient cooling configuration is achieved (see, for example, Patent Document 1).

特開２００２−３１３５３号公報（段落００１４、００１５、図１）JP 2002-31353 (paragraphs 0014, 0015, FIG. 1)

従来の加熱調理器は、グリルは金属のグリルケースで囲まれているだけであり、前面から吸い込んだ冷却風が、グリルを挟んで左右略対称の位置に配置されている制御装置や誘導加熱コイルを通過する前にグリルケースの金属表面によって温められるので、制御装置や誘導加熱コイルを十分に冷却できず、冷却効率が低くなるという問題があった。   In the conventional heating cooker, the grill is only surrounded by a metal grill case, and the cooling air sucked from the front is arranged in a substantially symmetrical position across the grill and the induction heating coil Since it is heated by the metal surface of the grill case before passing through, the control device and the induction heating coil cannot be sufficiently cooled, resulting in a problem that the cooling efficiency is lowered.

この発明は上記の問題を解決するためになされたものであり、吸気した冷却風が冷却風路を通る過程でグリルケースの外側壁で温められるのを防ぐことができ、冷却効率が高い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 problems, and can prevent the intake cooling air from being heated by the outer wall of the grill case in the process of passing through the cooling air passage, and cooking with high cooling efficiency. The purpose is to provide a vessel.

この発明に係る加熱調理器は、本体ケースと、この本体ケースの上部に設けられたトッププレートと、前記本体ケースの下部の左右方向の略中央に設けられたグリルと、このグリルと前記トッププレートとの間に設けられ、誘導加熱コイルまたは加熱源を搭載する仕切板と、前記グリルの左右両側の前面に各々設けられた吸気口に連通され、前記グリルのグリルケースの両側の外側面を各々所定の間隔をおいて覆った遮熱板、この遮熱板に対向する前記本体ケ−スの内側面、前記本体ケースの底面及び前記仕切板とで囲まれた下部冷却風路と、前記仕切板と前記トッププレートとの間に設けられ、前記下部冷却風路と前記トッププレートの排気口とを連通する上部冷却風路と、を備えたものである。   A heating cooker according to the present invention includes a main body case, a top plate provided on the upper portion of the main body case, a grill provided at a substantially center in the left-right direction at the lower portion of the main body case, and the grill and the top plate. And a partition plate for mounting an induction heating coil or a heating source, and an intake port provided on each of the left and right front surfaces of the grill, respectively, and outer side surfaces on both sides of the grill case of the grill. A heat insulating plate covered at a predetermined interval, an inner surface of the main body case facing the heat insulating plate, a lower cooling air passage surrounded by a bottom surface of the main body case and the partition plate, and the partition An upper cooling air passage that is provided between the plate and the top plate and communicates the lower cooling air passage with the exhaust port of the top plate.

この発明によれば、グリルの左右両側の前面に各々設けられた吸気口に連通され、グリルのグリルケースの両側の外側面を各々所定の間隔をおいて覆った遮熱板、この遮熱板に対向する前記本体ケ−スの内側面、本体ケースの底面及び仕切板とで囲まれた下部冷却風路を備えたので、本体ケースの前面から吸気した冷却風が冷却風路を通る過程でグリルケースの外側壁で温められるのを防ぐことができ、冷却効率をよくすることができる。   According to the present invention, the heat shield plate communicated with the intake ports provided on the front surfaces on both the left and right sides of the grill, and covers the outer side surfaces of both sides of the grill case of the grill at predetermined intervals, respectively. Since the lower cooling air passage surrounded by the inner surface of the main body case, the bottom surface of the main body case, and the partition plate is provided, the cooling air sucked from the front surface of the main body case passes through the cooling air passage. It is possible to prevent the grill case from being heated by the outer wall, and to improve the cooling efficiency.
