Abstract

An elevator air exchange system comprises an elevator car arranged in a well. An outer wall of a well building is a wall body. Through holes are formed in the upper end and the lower end of the side wall of the wall body of each floor, wherein a lower draught fan is arranged on the outer side of the through hole in the lower end. An air inlet is formed in the rear side of the top end in the elevator car and communicates with the interior of the elevator car. A fixing base is arranged at the bottom of the elevator car. An air outlet is formed in the bottom of the elevator car. An L-shaped air duct is arranged in the fixing base and communicates with the air outlet. The wall body is provided with corrugated pipes communicating with the through holes. An arc base is arranged at the free end of each corrugated pipe, wherein the middle portion of the arc base communicates with the corrugated pipe, and the arc base communicates with the air inlet and an air duct port. The elevator air exchange system is suitable for an elevator with an elevator shaft in the building outer wall, after the fire disaster happens and the elevator stops at a certain floor, the lower draught fan exhausts air outwards, outside air enters the elevator from the air inlet, and after the elevator is opened, air in a building also enters the elevator for ventilation. By means of the elevator air exchange system, after the elevator stops, the negative pressure for exhausting air outwards is formed, so that outside fresh air enters the elevator, air exchange is effectively conducted on the interior of the elevator car, and the quality of air in the elevator car is improved.
