When the grill 14 was pulled out of the grill cabinet 12 in order to return the object F, for example, the hot air due to the high-temperature combustion waste gas trapped in the upper part of the cabinet hardly overflows from the opening 60. Thus, the front portion of the top plate 34 is less likely to be heated by the waste gas.

In addition, since the temperature drop of the high-temperature combustion waste gas in the refrigerator due to the leakage of the hot air during the pulling can be reduced, when the grill 14 is pushed into the grill refrigerator 12 again, it is prompt. In addition, since cooking is restarted at an internal temperature suitable for heating the object to be cooked F, heat efficiency is good and gas consumption can be reduced.

As shown in the figure, a communication port 24 formed in a partition plate 20 at the depth of the grill storage 12 has a communication port 24 provided when the grill 14 on which the food F is placed is stored in the grill storage 12. In addition to being provided below the mounting surface, the upper end position of the opening 60 may also be provided below this mounting surface. In this way, when the grill 14 is pulled out of the grill chamber 12, the hot air generated by the high-temperature combustion waste gas trapped in the upper part of the chamber is less likely to overflow from the opening 60, so that the hot air can be prevented from flowing in front of the top plate 34. The part is not heated,
Since the hot air does not leak out during the pulling, the upper part of the grill storage 12 can be kept in a state in which high-temperature combustion gas is trapped. When the grill 14 is pushed into the grill storage 12 again, Cooking is immediately resumed at an internal temperature suitable for heating the object to be cooked F.

When the upper end of the opening 60 is provided below the mounting surface of the grill 14 as described above,
The seal member 56 for allowing the grill door 54 to contact the grill front portion 36 so as to maintain airtightness as described above may not be provided. The high-temperature combustion waste gas used for heating the object to be cooked F stays in the upper part of the grill storage 12 above the upper end of the opening 60, so that the grill door 54 of the opening 60
This is because the airtightness is not so required for the closed state.
