According to the technical scheme, the rainy day sensing intelligent door and window comprises a bottom plate, a glass window is installed in the bottom plate, a top plate is fixedly arranged at the top of the bottom plate, frames are fixedly arranged on the two sides of the bottom plate, and two symmetrically-distributed lifting mechanisms are arranged on the front side of the bottom plate; cleaning mechanisms are arranged on the inner sides of the two lifting mechanisms; the rainy day sensing intelligent door and window with the water stain self-cleaning function has the beneficial effects that the lifting mechanism composed of a motor, a reciprocating lead screw, a sliding base, a toothed plate, a gear and other components and the cleaning mechanism composed of an outer box, a driving wheel, a driven wheel, a transmission shaft, a cleaning brush, a sponge brush and other components are arranged; and through the cooperative design of a programmable logic controller (PLC) and a raindrop sensor, the problems that when an existing door and window is in rainy days, a large number of raindrops are left on window glass, the viewing sight of a user is affected, and an existing intelligent door and window does not have the function of cleaning the raindrops are solved.
