BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an okonomiyaki machine in which both sides are baked simultaneously, and more particularly, foodstuff is not scattered even by a closing operation of a lid, and okonomiyaki is a desired setting. There is a useful okonomiyaki machine that quickly opens the lid when the baking is completed at the temperature.

[0002]

2. Description of the Related Art Generally, okonomiyaki is usually baked on a large iron plate placed on a heat source such as a heater. Thus, in such okonomiyaki baking, even if only necessary portions are heated, the entire iron plate is heated, so that the heat source of electricity or gas is wasted, and the amount of hot air increases by that much, and the interior of the room increases. The okonomiyaki that can be baked more efficiently and speedily in order to reduce the waste of the heat source because it causes discomfort especially in the midsummer season due to the fact that it becomes hot without abuse. Various machines were devised.

Conventionally, as such an okonomiyaki machine, for example, as shown in FIG. 12, one or a plurality of holes (not shown) are provided on a table (flat plate) 2 provided at the upper end of a base 1. A baking dish (not shown) having an upper surface made of fluororesin is provided in these holes in a detachable manner, and a lid 3 and a table (not shown) mounted on the upper surface of the table (flat plate) 2 so as to be openable and closable. There is an okonomiyaki machine in which a heat source (not shown) is provided for each of the flat plate 2) (Japanese Utility Model Application Laid-Open No. 63-68939).
Reference).

[0004] Further, as shown in FIG. 13, in an okonomiyaki electric heating plate capable of simultaneously baking both sides, a corrugated heat storage plate 3 a _{3 serving} also as a holding of an electric heater 3 a ₂ is provided on the inner surface of an upper frame iron plate 3 a ₁ constituting a lid _3. the then fixed by arranging a plurality of electric heater 3a _2, top heater cover with wiring the power leads 8a outside the upper frame iron plate 3a _1, encompassing the upper surface of the upper frame iron plate 3a ₁ ( upper lid) and internally provided with heat insulating material 9 within 3B coated fixed to the upper surface of the upper frame iron plate 3a _1, and corrugated heat storage plate which also serves as a holding electric heater in the inner surface of the lower frame iron plate 2b constituting the table 2 (Not shown), a heater (not shown) is provided, and a power supply lead 8b is provided outside the lower frame iron plate 2b.

However, in the okonomiyaki machine disclosed in Japanese Utility Model Application Laid-Open No. 63-68939 and the okonomiyaki electric heating plate disclosed in Japanese Utility Model Application Laid-Open No. 59-99933, both are simultaneously used. Both sides of the okonomiyaki are baked, but the lid is simply covered on the upper surface of the baking dish, and the lid holding the heater is heavy, which makes the okonomiyaki soft. It has the disadvantage that foodstuffs are scattered by the closing operation of the lid, particularly in the okonomiyaki machine of the precedent, in order to prevent the opening and closing operation of such a lid behind the lid. In this case, a compression spring must be provided to urge downward. Furthermore, in these conventional okonomiyaki machines and the like, since the opening and closing operation of the lid is a manual operation, even if the okonomiyaki was baked in just the right condition, the lid opening operation of the lid was delayed. It was not unusual for the bread to be baked more than necessary, causing it to be missed or burnt.

[0006] The present invention has been made in view of such conventional problems, and does not scatter the ingredients even when the lid is closed. It is an object of the present invention to provide a useful okonomiyaki machine for opening the lid.
