The invention discloses a self-adjusting multifunctional window. The window is characterized by comprising an outdoor window body, an indoor louver, a sensing and detecting unit, a wireless receiving and transmitting unit, a voice recognition unit, a terminal control unit, a washing device and a single-chip microcomputer. Due to a brand new structural design, the firmness of the window is improved by controlling a rotary rod and a guide rail box to be used in a matched mode through a motor-driven gear structure, the window can be close to a wall when opened to the largest extent, and the functions of avoiding wind and protecting the window can be effectively achieved. The window is formed by combining two layers including the outdoor window body and the indoor louver, the two layers are used so that sealing, sound-isolation and safety properties can be improved, and loss of hot air can be effectively avoided in winter. By means of control of an indoor temperature sensor, an outdoor temperature sensor, a raindrop sensor and the single-chip microcomputer, automatic sensed opening and closing of the window are achieved, and the state of the window can be conveniently controlled. The two-layer window can be controlled through dual functions of the terminal control unit and the voice recognition unit, and the state of the window can be remotely controlled more conveniently.
