The heat reflecting surface is formed in a corrugated surface having a large number of rows of concave grooves having a V-shaped cross section, and a number of oil drain holes are provided at predetermined lengthwise intervals at the bottom of each concave groove on the corrugated surface. A heat reflection plate made of a metal plate having high heat reflection performance is installed, and radiant heat from the heating source in the direction of the saucer is reflected in the direction of the dish to improve the heating efficiency for the dish, and the oil content in the saucer is improved. Is configured to prevent the emission of heat from a heating source to reduce the generation of oil smoke due to the burning of oil.

That is, the heat reflecting plate in the above configuration is formed by molding the heat reflecting surface into a corrugated surface shape having a large number of rows of concave grooves having a V-shaped cross section. A number of oil drain holes are provided at predetermined intervals in the longitudinal direction at the bottom of the oil drain hole.

[0009] By utilizing the two tapered surfaces of the concave grooves in the V-shaped cross section, oil dripping from the food on the cooking net is effectively collected, and quickly dropped without stagnation. Thus, the oil is kept in the receiving tray below the large number of oil drain holes to prevent burning of oil on the heat reflecting plate.

On the other hand, this heat reflecting plate is, of course, made of a metal plate having a high heat reflecting performance, and the radiant heat from the heating source is transferred to the cooking net by the heat reflecting surface having a V-shaped cross section. By efficiently reflecting in the direction of the object,
While improving the heating efficiency of the cooked food, it also performs a reliable heat shielding function to the inside of the lower receiving pan, thereby preventing the oil collected in the receiving pan from burning and becoming a smoke source.

Therefore, according to the configuration, unlike the related art, it is not necessary to put water in the saucer, and the humidification of the cooked food is prevented. Therefore, the finish is improved, and the radiant heat from the heating source is used. Oil in the saucer is not burned and smoke is not generated.
