The invention discloses a factory upward window. The factory upward window comprises a frame, the inner wall of the fame is rotatingly connected with a window body through a rotating shaft, the frameis connected with the window body through a control mechanism, and the window body is internally provided with a cavity in which a sealing plate is arranged. According to the factory upward window, bymeans of a heat transfer plate, the temperature difference change in a first control cavity and a second control cavity can be small, and the temperature in the first control cavity and the second control cavity in a factory can be high; in rainy days, rainwater can flush the heat transfer plate to instantaneously reduce the temperature inside the first control cavity, according to the thermal expansion principles, the air pressure inside the first control cavity can be reduced, and the action of a first sealing plug and a second sealing plug, an abutting rod abuts against an abutting plate to trigger a control switch, then the control mechanism closes the window body; when not in rainy days, people can control the rotating direction of the abutting plate through an adjusting mechanism sothat a motor can work to conveniently control opening and closing of the window body.
