Abstract
The ventilation device of the elevator car comprises of an exhaust fan and an exhaust groove. The exhaust groove is vertically fixed along the elevator shaft and the groove is packaged with vertical frames which are in the shape of a ladder. The frames consist of two longitudinal beams and a plurality of cross beams. The longitudinal beams and the cross beams form a plurality of rectangular blocks and the frame edges are projected. The vertical frames have a plurality of air doors. The air door shafts are arranged inside of the cross beams. The upper exit of the exhaust groove is equipped with an exhaust blower. The exhaust fan is arranged at the top of the elevator car, the exhaust blower opens into the elevator car, and the air outlet faces the air door. The air outlet has wear resistant elastic rubber blocks and the size of the rubber block is consistent with the groove. The ventilation device can force the air inside of the elevator car to be exhausted out of the elevator car very quickly, which therefore enables the air inside the elevator car can be refreshed in time. The utility model effectively protects the elevator passengers, and has a simple structure and reliable safety.
Description
Affiliated technical field
The utility model technology relates to a kind of drafting apparatus, especially relates to a kind of drafting apparatus that is used to improve ventilation condition in the lift car.
Background technology
Lift car is easy to be pathophorous space narrow and small relatively, that air flows is difficult for.The aeration technology of existing lift car has two kinds: a kind of is that sedan-chair is top-loaded with fan and blows downwards; Another kind of technology is to be top-loaded with an air-exhaust fan at sedan-chair, upwards (hoistway) exhausting.The former shortcoming is effectively the air in the car to be upgraded in time, and carbon dioxide or germ that the passenger is breathed out quicken to spread in car; The shortcoming of a kind of technology in back is that the air in the car is taken out toward relative fully enclosed elevator hoistways, and these air are easy to reflux from the slit between car door and the Room door.More than the renewals that all can not solve air in the lift car well of two kinds of technology, spread disease germs easily, all be unfavorable for the health of elevator passenger.If the carrier of similar SARS virus is arranged among the elevator passenger group, more than two kinds of technology all can bringing on a disaster property consequence.
The utility model content
The purpose of this utility model, just be to provide a kind of drafting apparatus that is used to improve ventilation condition in the lift car, it can upgrade the air in the car in time, one can avoid carbon dioxide or germ that the passenger breathes out to quicken to spread in car, second can avoid the air in the car taken out toward relative fully enclosed elevator hoistways and from the slit between car door and the Room door being back to car; More effectively protect the health of elevator passenger.
For achieving the above object: drafting apparatus of the present utility model is characterized in that: comprise exhaust fan and air draft groove; Described air draft groove along hoistway vertically install, vertical sash be housed in the groove, sash is ladder shape, is that two longerons and many crossbeams constitute, and constitutes a plurality of rectangle frames between longitudinal and cross beam, frame is along protrusion; The sash inner face is equipped with the air door group, and axle of the air door is contained in the crossbeam; Described exhaust fan is loaded on that sedan-chair top, suction opeing are led in the car, air outlet is facing to aforementioned air door.
On the basis of the above, the utility model is done further to improve:
1) described air draft groove upper outlet is equipped with air suctiton ventilator.
2) described exhaust fan air outlet is equipped with wear-resisting elasticity blob of viscose, and its size adapts to the wind groove.
Described air door is exactly the door that door-hinge level, door leaf are very thinly very gently installed down, opened in the groove in fact; When car moved up and down, sedan-chair top exhaust fan moved up and down with car, and the air outlet of exhaust fan is facing to air door, when sedan-chair top exhaust duct moved to certain position, air-out blew air door open, and wind enters the wind groove and discharges, when air outlet left a certain damper positions, the air door by gravity can SELF CL.
The beneficial effects of the utility model: the force air ground in the car is discharged outside the railway carriage or compartment fast, the air in the car can be upgraded in time, protect the health of elevator passenger effectively.And it is simple in structure, safe.

Among the figure: exhaust fan 1, wind groove 2, sash 3, sash convex edge 4, sash crossbeam 5, sedan-chair top exhaust fan fixed support 6, air door 7, axle of the air door 8, wind groove outlet air suctiton ventilator 9, wear-resisting elasticity blob of viscose 10, car 11.
The specific embodiment
The drafting apparatus that is used to improve ventilation condition in the lift car of the present utility model as can be seen from FIG. comprises exhaust fan and rectangle air draft groove; The air draft groove vertically install in (also can just at the hoistway internal recessing), the groove along hoistway vertical sash is housed, sash is ladder shape, is that two longerons and many crossbeams constitute, and constitutes a plurality of rectangle frames between longitudinal and cross beam, rectangle frame is along there being chimb to protrude, longeron is adjacent at trough rim; The sash inner face is equipped with a plurality of air doors, and the axle of the air door level is contained in the crossbeam, and the air door door leaf is very thin very gently to be installed down, open in groove; Exhaust fan is loaded on the support on sedan-chair top, suction opeing leads in the car, air outlet is facing to aforementioned air door and wear-resisting elasticity blob of viscose is housed, and its width and wind groove adapt, and prevent to leak out; Air draft groove upper outlet is equipped with little air suctiton ventilator and helps air draft.
When car moved up and down, sedan-chair top exhaust fan moved up and down with car, and the air outlet of exhaust fan is facing to air door, and when sedan-chair top exhaust duct moved to certain position, air-out blew air door open, and wind enters the wind groove and extracted out outside the hoistway by air suctiton ventilator; When air outlet left a certain damper positions, the air door by gravity can SELF CL.
