Japanese Unexamined Patent Publication No. 2017-44370

However, in the case of a table stove that omits the grill storage, there is no grill storage that supports the mounting table, so that the stove burner cannot be supported. Therefore, if we tried to design a mechanism to support the stove burner separately, the number of needs for the table stove without the grill was significantly smaller than the number of needs for the table stove with the grill, so the grill was omitted. It was difficult to provide a table stove at a low price. Therefore, it is desirable to design a table stove that omits the grill storage by using the existing parts of the table stove with a grill as much as possible, but if the grill storage is omitted, that part becomes a space part. Therefore, there is also a problem that the strength of the housing cannot be maintained.

An object of the present invention is to provide a stove that can utilize existing parts and maintain the strength of a housing even if the stove omits the grill.

The grill according to claim 1 includes a rear plate portion, a left plate portion, a right plate portion, and a bottom plate portion that connects at least the front end side of the lower end portions of the left plate portion and the right plate portion.
