The ventilation fresh air device comprises a first shell arranged at the top of an inner car and second shells arranged at the lower ends of the left side face and the right side face of the inner car, a first shielding part is arranged in the first shell, and a second shielding part is arranged in the second shell. When the elevator ascends, air in the hoistway can enter the inner car through the ascending air inlet pipe under the action of the positive pressure at the top of the car and is exhausted through the ascending air outlet pipe, and when the elevator descends, the air in the hoistway can enter the top of the inner car through the descending air inlet pipe under the action of the positive pressure at the bottom of the car and is exhausted from the bottom of the inner car through the descending air outlet pipe. A good ventilation effect is achieved when the elevator car ascends or descends, and the ventilation and purification capacity in the elevator car is improved.
本发明涉及一种用于电梯的换气新风装置,包括设于内厢顶部的第一壳体和设于内厢左右侧面下端的第二壳体,所述第一壳体内部设置有第一遮挡部件,所述第二壳体内部设置有第二遮挡部件。本发明在电梯上行时,井道内空气通过轿厢顶部正压的作用能够经上行进风管进入内厢并经上行出风管排出,在电梯下行时,井道内空气通过轿厢底部正压的作用能够经下行进风管进入内厢顶部并经下行出风管从内厢底部排出,实现了电梯轿厢在上行或下行时都具有较好的换气效果,提高了轿厢内部的通风净化能力。
