The invention discloses a multifunctional vertical grilling machine, and belongs to cooking equipment. Existing grilling machines are single in function, the scorch degree of grilled food is nonuniform, and oil drainage of the food is not ideal during the grilling process. By rotationally assembling a first grill body and a second grill body on a base, the first grill body and the second grill body can be opened to be in a horizontally arranged mode or in the vertical mode of moving closer to the vertical part of the base respectively when in use, the first grill body and the second grill body can grill different foods respectively and can grill meat, grill bread, dry eggs and bacon and the like simultaneously, breakfast dishes, lunch dishes and dinner dishes are made, functional diversity is achieved, and the product can be vertically grilled and collected; vertical grilling can be conducted to achieve adequate oil drainage, and the grilling time can be greatly shortened; vertical grilling ensures that the two sides of the food can make full contact with the heating surface of a grilling plate, and the food shapes and the surface scorch degree are made to be uniform.
