して視認できるため、それを加熱時の目印としている。Conventionally, a dark-colored crystallized glass plate that blocks visible light and transmits infrared light is used as a top plate of a cooking device provided with an infrared heating device. The blocking of visible light is intended to make the internal structure of the heating device and the like difficult to see at room temperature and to reduce strong visible light emission from the halogen heater to prevent glare. In addition, in this type of cooking device, the heater part that is red-hot can be visually recognized through the dark-colored crystallized glass plate, so that it is used as a mark when heating.

化ガラス板が用いられつつある。A cooker provided with an electromagnetic induction heating device does not generate visible light unlike an infrared heating device.
There is no lighting of the heater part that serves as a mark during heating. Therefore, in the electromagnetic cooker, the electromagnetic heating power is being separately displayed using a light emitting diode or the like. Some of the heating power indicators are provided on the side of the cooking device, but those that can be installed near the heating portion to check the heating power through the top plate are becoming mainstream. However, since the light emitted from the light emitting diode is not as strong as the light emitted from the conventional infrared heater, the light emitted from the diode is not conspicuous on the dark-colored crystallized glass plate, which makes it difficult to see. Therefore, a transparent crystallized glass plate is being used for such a top plate.

厚みが増して基板との間に生じる熱膨張差による応力が
過大となりクラックや剥離の問題が生じる。When a transparent crystallized glass plate is used as a top plate for a cooker, it is necessary to hide the internal structure of the heating device and the like located under the top plate for design reasons. Therefore, it is necessary to apply a light-shielding layer to the entire area of the transparent crystallized glass plate except the surface area of the light emitting diode. Furthermore, on the top plate,
In addition to this light-shielding layer, a heater layer and a decorative layer indicating cautionary notes are necessary, but if a light-shielding layer is applied on the cooking surface side by a general method and the decorative layer is overcoated on it, the thickness of the applied layer is reduced. Furthermore, the stress due to the difference in thermal expansion between the substrate and the substrate becomes excessive, causing problems such as cracking and peeling.

Further, the porous membrane is not preferable because the abrasion damage due to contact with a cooking utensil or the like becomes severe.

では緻密な無機顔料層を採用している。On the other hand, a glossy and smooth surface is required on the front side of the top plate. In general, a transparent crystallized glass plate originally satisfies these characteristics sufficiently, and therefore it is preferable to minimize the area where the decorative layer is formed. In the present invention, the light-shielding layer is applied to the back side, so that the decorative layer on the front side can be minimized. Furthermore, since the decorative layer is required to have gloss and smoothness, a dense inorganic pigment layer is used in the present invention.

It is preferably 1 to 50 μm, and particularly preferably 0.2 to 40 μm. When the thickness is 0.1 μm or more, visible light can be sufficiently shielded for hiding decorations and heating devices. Further, when it is 50 μm or less, problems such as peeling of the coating layer, cost increase, and glass coloring due to increase of impurities when remelting and recycling the crystallized glass plate are less likely to occur.

式会社製Ｎ−０がある。The transparent crystallized glass plate in the present invention is preferably colorless transparent low expansion crystallized glass,
Colored transparent crystallized glass may be used as long as the object of the present invention is achieved. The crystallized glass plate is required to have low expansion because heating and cooling are repeated.
Particularly, the average linear thermal expansion coefficient at 30 to 750 ° C is -10.
To + 30 × 10 −7 / ° C., especially −10 to + 20 × 10 −7 /
It is desirable to use those in the range of ° C. When the coefficient of thermal expansion is within the above range, the difference in expansion does not cause cracking due to the temperature distribution inside the top plate during heating. An example of crystallized glass that satisfies this condition is N-0 manufactured by Nippon Electric Glass Co., Ltd.

した後、裏側の遮光層を形成してもよい。The top plate for a cooker of the present invention is manufactured as follows. First, a low-expansion transparent crystallized glass plate molded and processed into a predetermined size is prepared. In addition, the mixed powder obtained by mixing the inorganic pigment and the glass powder in a predetermined ratio is made into a paste to prepare a light shielding layer paste. Then, a light-shielding layer paste is printed on the heating device side (back side) of the crystallized glass plate by a method such as screen printing, dried, and baked to form a light-shielding layer. Furthermore, the mixed powder obtained by mixing the inorganic pigment and the glass powder in a predetermined ratio is made into a paste,
A paste for a decorative layer is prepared. Then the cooking side (front side)
This paste is printed on and dried and baked to form a decorative layer. In this way, the cooker top plate of the present invention can be obtained. Note that the light shielding layer on the back side may be formed after the decoration layer on the front side is formed first.

てもよい。In the case of a cooker having an infrared heating device, it is required that the infrared heating portion of the top plate has a high infrared transmittance. Therefore, in order to increase the infrared transmittance of the light shielding layer, it is preferable to reduce the print density or reduce the film thickness of the inorganic pigment layer in the infrared heating portion. A raster layer having a high infrared transmittance may be formed instead of the inorganic pigment layer.

When forming the openings, it is desirable that the openings are uniformly distributed over the entire infrared heating portion. The size of each aperture is
