Abstract

The invention discloses a ventilation device and an elevator car provided with the same. The elevator car comprises a car roof, a car bottom, a car wall, a car door and a ventilation device. The ventilation device comprises a ventilation equipment mounting plate, a lower sealing plate, a side sealing plate and ventilation equipment; the ventilation equipment mounting plate, the lower sealing plateand the side sealing plate are connected to form at least two cavities which are different in size and communicate with one another; the ventilation equipment mounting plate and the lower sealing plate are provided with ventilation openings; the ventilation equipment is installed on the ventilation equipment mounting plate, an air outlet of the ventilation equipment is in butt joint with the ventilation opening of the ventilation equipment mounting plate, the ventilation opening of the lower sealing plate is in butt joint with an air inlet of the car roof, and the ventilation opening of the ventilation equipment mounting plate and the ventilation opening of the lower sealing plate are staggered in the height direction and the horizontal direction. When the elevator runs, noise outside theelevator car can be greatly attenuated and running noise of the ventilation equipment and the like are transmitted into the elevator car through the elevator ventilation device, so that the noise problem in the elevator car is remarkably solved, and riding comfort is improved.

Description

technical field [0001] The invention relates to elevator equipment, in particular to a ventilation device and an elevator car equipped with the ventilation device. Background technique [0002] When the elevator car is running in the elevator shaft, it will generate wind noise, intrusion noise, machine room noise and other external noise excitations. These noises can easily spread into the car through the air inlet of the elevator ventilation device. [0003] In the traditional structure, a simple ventilation equipment cover is used to attenuate these external noises from propagating into the car interior, but the sound insulation effect of this elevator ventilation device is relatively poor. And when the ventilation equipment is running, the blades of the ventilation equipment will generate aerodynamic noise. Since the ventilation equipment is directly installed on the car roof, such as figure 2 As shown, so simple ventilation hoods do little to eliminate this aerodynamic ...
