The invention relates to an elevator car ventilation device which comprises an air duct arranged in an elevator car wall and used for air flow communication inside and outside an elevator car. The air guide plate is arranged on the side, close to the air duct inlet, in the air duct and connected with the car wall through a rotating shaft on the air guide plate; the fan is arranged on the side, close to the air duct outlet, in the air duct and used for working when the elevator car is static; and the air guide plate is in a horizontal state when the fan works. According to the elevator car ventilation device, the air flue is arranged in the car, the air guide plate with the self-balancing function is arranged at one end of the air flue, and the fan is arranged at the other end of the air flue; when the elevator runs, the air guide plate rotates in a fixed direction under the action of airflow for ventilation; when the elevator stops, the fan is started for forced ventilation. Therefore, no matter the elevator is in a running state or a static state, a good ventilation effect in the lift car can be realized.
本发明涉及一种电梯轿厢通风装置,包括:风道,设置于电梯轿壁内,用于轿厢内外气流连通;导风板,设置于所述风道内靠近风道进口的一侧,并通过其上的转动轴与轿壁相连;风扇,设置于所述风道内靠近风道出口的一侧,用于在电梯轿厢静止时工作;其中,所述导风板在风扇工作时处于水平状态。本发明所设计的电梯轿厢通风装置,通过在轿厢内设置风道,风道一端设置具有自平衡功能的导风板,另一端设置风扇;电梯运行时,导风板在气流作用下转动固定方向进行通风;电梯停止时,启动风扇强制通风。这样,无论电梯处于运行或静止状态,都可以实现轿厢内的良好通风效果。
