The utility model provides an opening multi-person stove which can bake bread. When respective expansion angles of a left-side heating plate and a right-side heating plate of a stove core are smaller than 90 DEG, after a grill is arranged, the utility model can bake a plurality of food with larger volume (such as hamburger); when the expansion angles are equal to 90 DEG, the utility model can cause the food (such as hamburger) with larger volume to be directly arranged on a bread net rack for roasting. A flank heating plate and a side plate are made into a side plate component which is integrally formed, and the side plate component can rotate around a wheel shaft at the bottom of the side plate. The utility model has the advantages that when the left and the right side plate components are at the position (alpha=0) which is perpendicular to a base of the multi-person stove, various functions (bread baking) of the multi-person stove can be realized. When the side plate components expand a certain angle which is not perpendicular to the base of the multi-person stove (alpha is larger than 0 and is no larger than 90 DEG), the utility model can cause the food (such as hamburger) with larger volume to be arranged on the grill or the bread net rack for roasting.
