発明が解決しようとする問題点 ところがこのような従来使用されてきた非粘着性塗膜は
一般に熱可塑性樹脂である。従って、加熱室内が高温時
に、天板を出し入れすると天板の荷重と摩擦により非粘
着性塗膜が摩耗し加熱室の基材が露出してしまうという
問題点があった。The problem to be solved by the invention is that the conventionally used non-tacky coating film is generally a thermoplastic resin. Therefore, when the top plate is taken in and out when the temperature of the heating chamber is high, the load and friction of the top plate cause the non-adhesive coating film to wear and the base material of the heating chamber to be exposed.
問題点を解決するための手段 このような問題点を解決するために、本発明は非粘着性
塗膜の中にマイカを充填するものである。Means for Solving Problems In order to solve such problems, the present invention fills mica in a non-adhesive coating film.
作用 硬度の高いマイカを充填することにより、天板との摩擦
があっても多数のマイカが荷重を分散して受け、しかも
硬度が高いため摩耗しにくい。従って耐摩耗性が向上す
るのである。Action By filling mica with high hardness, even if there is friction with the top plate, a large number of mica receives the load in a dispersed manner, and since it has high hardness, it is hard to wear. Therefore, the wear resistance is improved.

用なものである。The heating cooker configured as described above can perform both heater heating and high frequency heating. With the above configuration, even if the top plate 16 slides on the protrusion 15,
A large number of mica receives the load in a distributed manner, and since the hardness is high, the non-adhesive coating film 28 does not easily wear. As a result of the abrasion resistance test, it was found that the abrasion resistance was more than doubled as compared with the paint containing no mica. Mica itself has a low dielectric constant and has a high insulating property. Therefore, it is particularly useful in a cooker capable of high frequency heating as in the present invention.
