The iron plate 13 is heated by the flame 12 and the gyoza or the like placed on the iron plate 3 is heated. In the case of cooking that requires both steam heating and iron plate heating, such as dumplings, steam is generated by putting water into an iron plate 3 having a concave portion, and heating is performed using this steam. Note that the cooking chamber 14 is provided with a lid 15 so that the steam does not escape to the outside.

[0003]

However, in such a cooking method, there is a problem that the cooking time is lengthened because the iron plate 13 is rapidly cooled by water. In addition, since the cooking state changes depending on the amount and distribution of water, there is also a problem that the baking is not uniform unless the operation is skillful.

[0004] The present invention has been made to solve the above problems, and an object of the present invention is to provide a griddle that can shorten the cooking time and can perform good cooking without skill in operation. .

[0005]

A first means for solving the above-mentioned problem is a griddle used for cooking dumplings or the like, which is heated by a burner used for heating an article to be cooked and is steamed. And a steam generator for supplying steam into the cooking chamber.

[0006] In this means, steam from the steam generator is supplied into the cooking chamber, and heating by the steam is performed simultaneously with heating from the iron plate. Therefore, the cooking time is shortened because the iron plate is not rapidly cooled unlike the prior art. In addition, since the steam from the steam generator spreads uniformly in the cooking chamber, the baking is uniform in all places. The expression "heated by the burner" includes not only a case where the burner is directly heated by the flame of the burner but also a case where it is indirectly heated by the burner gas or the like.

[0007] A second means for solving the above-mentioned problems is as follows.
The first means is characterized by comprising a preheater for preheating water supplied to the steam generator by exhaust gas from a burner (claim 2).

[0008] In the present means, since a water preheater is provided, thermal efficiency is improved and the temperature of steam can be increased. Therefore, the cooking time can be reduced.

[0009] A third means for solving the above problems is as follows.
The first means or the second means, wherein the exhaust gas from the burner is exhausted to the outside through a cooking chamber (claim 3).

In this means, heating by convection is performed by flowing the exhaust gas of the burner into the cooking chamber, so that the cooking time can be reduced.

[0011] A fourth means for solving the above problems is as follows.
Any one of the first means to the third means, further comprising a steam heater for heating steam from a steam generator with exhaust gas from a burner. ).

In the present means, since the steam is heated by the steam heater, the temperature in the cooking chamber can be increased, and the cooking can be speeded up.
