Thus, even if boiled juice or the like enters from the periphery of the exhaust pipe 19 of the grill portion 4, it can be prevented from adhering to the pipe connector 52 or the internal gas pipe 55 in the housing 2. In addition, even when there is a large amount of broth etc., it can be guided onto the pipe cover 58 and dropped to the rear side of the grill portion 4, so that it is possible to suitably prevent the soup from sticking to the internal gas pipe 55 or the electric material parts. Become.
In particular, here, the folded-back portion 65 projecting upward is formed at the projecting end portion of the cover portion 64, so that the broth can be damped and reliably guided onto the pipe cover 58.

The shapes of the blocking plate, the cover part, the folded part, and the piping cover can be changed as appropriate, and the protruding length and width of the cover part may be increased or the upward angle may be increased. If the clogging of the broth or the like can be reliably performed by the shape of the cover portion, the folded portion can be omitted.
Moreover, in the said form, although the 2nd gas inlet and the piping connection tool are arrange | positioned on the left side of a grill part, the right side of a grill part may be sufficient.

(About the structure of the gas supply device)
Next, the structure of the gas supply device 70 will be described.
As shown in FIGS. 5, 7, and 13, the gas supply devices 70, 70... Have four corresponding to the three stove parts 3 and the grill part 4, and two on the left and right sides of the grill part 4.
