A leveling foot structure for a household appliance comprises a base, a first fastener, and a position-limiting block. A through-hole is arranged at a side wall of the base. The position-limiting block is movably connected to the base by means of the first fastener. The first fastener partially passes through the through-hole to connect to the position-limiting block. The position-limiting block is rotatable around an axis of the first fastener, and is movable along an axial direction of the first fastener. After rotation of the position-limiting block, the position-limiting block at least partially protrudes from a bottom surface of the base.
