The invention relates to a multifunctional ladder. The technical scheme includes that four support legs of a herringbone ladder are respectively provided with airing rods, one end of each airing rod is movably hinged to the corresponding support leg, the other end of each airing rod can parallelly or vertically rotate, support points are arranged in the middles of the airing rods, particularly, strip-shaped grooves are formed in the middles of the airing rods, one end of each support sheet is inserted into the corresponding strip-shaped groove, and the other end of each support sheet is hinged to the corresponding support leg. Only the support sheets need to be gently upwardly lifted when the airing rods are about to be contracted, so that the support sheets can be withdrawn from the strip-shaped grooves, and the support sheets and airing frames can descend and return together. The multifunctional ladder is a household ladder when the airing rods are contracted, airing and climbing functions do not interfere with one another, but the volumes of the airing rods and the household ladder can be greatly reduced. The multifunctional ladder has the advantages of multiple functions, compactness, convenience and easiness in implementation.
