Description of the Related Art Generally, in an electromagnetic cooker having a cooking plate such as white ceramic glass on the upper surface, a pot for boiling is placed on the cooking plate, so that spilled water or water splashes on the surface. Considering the case, so as not to flood the inside of the body,
It was necessary to apply waterproof treatment between the cooking plate and the body case to attach it. Usually, the most suitable method in terms of work and cost is to apply a sealant 3 such as silicone resin between the cooking plate 1 and the body case 2 as shown in FIG. It is to keep.
発明が解決しようとする問題点 さて、第５図のようにこの種の加熱調理器において、新

膜に浸潤しないようにしたものである。Means for Solving the Problems In order to solve the above problems, the present invention supports a cooking plate formed by baking an inorganic heat-resistant coating film on the back surface of a translucent member at a high temperature, and the cooking plate. With a body case,
A silicone resin-based sealant for fixing the container case and the cooking plate is provided, and an organic coating material having a volatile solvent component is formed on the outer peripheral portion of the surface of the cooking plate having the heat resistant coating film. Apply an overcoat agent,
The sealing agent is applied between the cooking plate and the container case via the overcoating agent so that the solvent component of the sealing agent does not infiltrate the heat resistant coating film by the overcoating agent.

る。7 is a cooking plate, 8 is a case, 9 is a sealant such as a silicone resin, and 10 is a heating coil. Here, the cooking plate 7 is made of heat-resistant transparent glass 1 such as ceramics.
A coating film 12 (hereinafter referred to as a heat-resistant coating film) 12 made of a heat-resistant inorganic material such as a silicon base material is baked on the back surface of 1 at a high temperature (700 ° C. or higher) and applied, and is in contact with the sealing agent 9. The overcoat agent 13 is applied to the peripheral area. As the overcoating agent 13, a quick-drying organic coating material containing a large amount of volatile solvent components inside, for example, household acrylic lacquer or the like is inexpensive and has good performance. The organic coating can be used for the overcoat agent 13 is
This is because the coated portion is the peripheral portion of the body away from the heating coil 10 and the cooking pot 14 and does not require high heat resistance.
オーバーコート剤１３の材料は上記のように高い耐熱性

（すきま）にそれ自体が浸潤しないものであれば良く、
前記有機塗料だけでなく、種々の材料が採用できる。Since the material of the overcoat agent 13 does not need to have high heat resistance as described above, any material that does not itself infiltrate into the heat resistant coating film 12 (crevice) of the cooking plate 7 may be used.
Various materials other than the above-mentioned organic paint can be adopted.
さて、以上の構成において本実施例の作用、効果を説明

等採用不可能であり、非実用的である。That is, the sealant 9 is the heat resistant coating film 1 on the cooking plate 7.
The coating film of the overcoating agent 13 applied on the surface 2 prevents the heat-resistant coating film 12 from seeping inside, so that the heat-resistant coating film 12 is not discolored. Here, discoloration due to the sealant 9 is more likely to occur than the organic paint used for the overcoat agent 13 because the sealant 9 itself is hard to cure and the solvent is hard to volatilize. The sealant 9 that cures very quickly cannot be used because of the mounting of the cooking plate 7 and is impractical.

理器を実現した。EFFECTS OF THE INVENTION As is clear from the above examples, according to the present invention, a translucent heat-resistant glass coated with a heat-resistant coating film on the back surface is coated with an overcoat agent for preventing sealant infiltration. By doing so, it was possible to perform waterproofing between the cooking plate and the body case, which was very difficult in the past, with an inexpensive sealant such as silicone resin, which is one of the major problems in colorizing the cooking plate. Has been eliminated, and a cooker with great design has been realized.
