Problems solved by technology

When the elevator is in a power failure state, the air flow in the car is reduced because the ventilation equipment stops operating and the ventilation hole area is small
At this time, if there are people trapped in the car, it may cause the trapped people to have difficulty breathing due to lack of oxygen, especially when there are many trapped people, the situation is more serious.

Abstract

The invention discloses a ventilation device for an elevator car, which comprises a ventilating port arranged on the roof of the elevator car, a fixed frame, a guide frame arranged on the fixed frame,wherein, the fixed frame is arranged on the roof of the elevator car at the ventilating port; the guide frame is provided with a cover or an emergency-ventilation action piece which goes through theventilation port. The device of the invention has the advantages of increasing effective ventilation area in the elevator car in case of power failure, remarkably improving the ventilation situation in the elevator car, reducing the oxygen deficiency rate of trapped people with significant effect.

Description

technical field [0001] The invention relates to a ventilation device in an elevator car. Background technique [0002] In general passenger elevators, the car ventilation system is usually equipped with ventilation holes, and electrical equipment such as cross-flow fans or air conditioners are used to enhance the ventilation effect. The effective area of ​​the ventilation holes is generally slightly larger than 1% of the effective area of ​​the car. When the elevator is in a power failure state, the air flow in the car is reduced because the ventilation equipment stops running and the area of ​​the ventilation holes is small. At this time, if there are people trapped in the car, it may cause the trapped people to have difficulty breathing due to lack of oxygen, especially when there are many trapped people, the situation is more serious. Contents of the invention [0003] The purpose of the present invention is to provide an elevator car ventilation device, which can be o...
