Description

本発明は主として一般家庭または厨房等で使用される鉄やステンレス製はもとより銅やアルミニウム等の材料で形成された調理器具も加熱できる誘導加熱調理器に関するものである。   The present invention relates to an induction heating cooker that can heat cooking utensils formed of materials such as copper and aluminum as well as iron and stainless steel used mainly in general households or kitchens.

近年、台所で使用される加熱調理器として、火を使わない安全でクリーンな熱源である誘導加熱調理器が普及し始めている。この誘導加熱調理器に使用される天板については、明るい系統の色調が目立つようになり、メタリック調のシルバーあるいはゴールドあるいは青、赤といったものも見受けられるようになってきた。また、天板においては操作表示や火力表示に発光体を使用し、この天板を介して表現するものが主流となってきている。   In recent years, induction cooking appliances that are safe and clean heat sources that do not use fire are becoming popular as cooking appliances used in kitchens. About the top plate used for this induction heating cooker, the color tone of a bright system became conspicuous, and things such as metallic silver, gold, blue, and red have come to be seen. Moreover, in the top plate, the thing which uses a light-emitting body for an operation display and a thermal power display, and expresses via this top plate has become mainstream.

しかしながら、こういったメタリック調の色調を出すためには、無機顔料を配合するため、配合量によっては、焼成時に顔料の無機顔料が溶解できず印刷強度が低下するという課題と、メタリック調に発色するため透光性が低下するという課題を有していた。   However, in order to achieve such a metallic color tone, an inorganic pigment is blended, so depending on the blending amount, the inorganic pigment of the pigment cannot be dissolved at the time of firing, and the printing strength is lowered, and the color tone is metallic. Therefore, there was a problem that translucency is lowered.

従来のメタリック調の天板として以下の構成のものがある(例えば、特許文献1参照)。前記従来のメタリック調の天板は、無機顔料を被覆してなるパール調の材料と、シリコンレジンまたは、シリカ質ゾルとからなるパール調絵具層を絵付け焼成してなる透光性低膨張ガラスセラミックであった。

As a conventional metallic-tone top plate, there is one having the following configuration (for example, see Patent Document 1). The conventional metallic-tone top plate is a light-transmitting low-expansion glass obtained by painting and baking a pearl-like paint layer made of a pearl-like material coated with an inorganic pigment and a silicon resin or a siliceous sol. It was ceramic.

しかしながら、前記構成では無機顔料を配合するため、配合量によっては、焼成時に顔料の無機顔料が溶解できず印刷強度が低下するという課題と、メタリック調に発色するため透光性が低下するという課題を有しており実用的ではなかった。   However, since the inorganic pigment is blended in the above configuration, depending on the blending amount, the inorganic pigment of the pigment cannot be dissolved at the time of firing, and the printing strength is lowered, and the translucency is lowered because the color is colored metallic. It was not practical.

本発明は、上記従来の課題を解決するもので印刷強度が強く、透光性あるいは遮光性自由自在で意匠性の高いメタリック調の天板を備えた誘導加熱調理器を提供するものである。   The present invention solves the above-described conventional problems, and provides an induction heating cooker having a metallic top plate having high printing strength, high translucency or light shielding ability, and high design.
