The fresh air system for the elevator car comprises a car body, a car top and a treatment box, and the treatment box is fixed to the top end of the car top through bolts; a box cover is fixed to the top end of the treatment box through bolts. An internal circulation type air flowing design is adopted, after air in the lift car body is pumped into the air return cavity, air filtered twice through the activated carbon filter plate, the photocatalyst filter plate and the efficient filter screen enters the lift car body through the air inlet cavity, and therefore the air can enter and exit from the interior of the treatment box and the interior of the box cover; heat exchange is facilitated through a total heat exchange chip, the stability of the air temperature in the lift car is guaranteed, the influence of vertical movement of the lift car body on the fresh air system is reduced, and the interior of the treatment box can be overhauled after the box cover is opened; the problems that in an existing fresh air system, an air inlet and outlet pipeline is located on the outer side, is prone to being affected by lifting of a lift car and is prone to damage, and follow-up maintenance is inconvenient are solved, and the practicability of the fresh air system is greatly improved.
本发明公开了用于电梯轿厢的新风系统,包括轿厢主体、厢顶和处理箱,所述厢顶顶端通过螺栓固定有处理箱;所述处理箱顶端通过螺栓固定有箱盖。采用了内循环式空气流动设计,轿厢主体内部的空气被抽至回气腔内部后,经过活性炭过滤板、光触媒滤板和高效过滤网两次过滤后的气体通过进气腔进入轿厢主体内部,从而在处理箱和箱盖内部即可完成进出,且通过全热交换芯片方便进行换热,保证轿厢内气温的稳定性,减小轿厢主体上下移动对新风系统的影响,箱盖打开后,即可对处理箱内部进行检修,解决了现有的新风系统中进出气管道位于外侧容易受到轿厢升降影响、容易损坏且后续检修不便的问题,大大的提高了新风系统的实用性。
