Elevator system with active air supply

Abstract

The invention discloses an elevator system with active air supply. The elevator system with the active air supply includes a lift car, a traction system and a counterweight, and further includes a fresh air part, a butt-joint portion and a lift car ventilation system, wherein the butt-joint portion communicates with the fresh air part and the car ventilation system; the fresh air part includes a aventilation pipe, an exhaust fan, a first vent and a second vent; a sliding rail is arranged on the outer wall of the ventilation pipe, and the butt-joint portion can slide along the sliding rail; the butt-joint portion includes a first connector, a power assembly, a connecting pipe and a second connector; and the lift car ventilation system includes a top air outlet assembly and a side wall airoutlet assembly, the top air outlet assembly and the side wall air outlet assembly are all connected with the ventilation pipe, and the ventilation pipe communicates with the butt-joint portion. According to the elevator system with the active air supply, the fresh air outside an elevator shaft can be sent into the lift car, so as to quickly improve the air quality in the lift car, and the ridingcomfort is improved.

Description

Technical field [0001] The invention relates to the field of elevator equipment, in particular to an elevator system with active air supply. Background technique [0002] In order to improve the air quality in the elevator car, the existing car is often equipped with exhaust fans and ventilation holes to realize the circulation of the air in the car. However, the fresh air in the car comes from the elevator shaft. As a relatively closed space, the air in the elevator shaft contains a lot of mechanical lubricating oil, dust and other odors. The overall air quality in the car is poor. Pregnant women or the elderly with poor physical fitness often feel bored in a small car, which affects their health. The existing car also provides a ventilation method. Ventilation holes are arranged around the top of the car. During the operation of the elevator, wind is directly poured into the car from the ventilation holes and directly affects the standing car. The ride experience of the surr...

Problems solved by technology

The existing car also provides a ventilation method. There are ventilation holes around the top of the car. During the operation of the elevator, the wind is directly poured into the car from the ventilation holes, which directly affects the air flow of the car standing on the air. The ride experience of passengers around

[0003] In addition, in the existing ventilation devices, the size of the ventilation cannot be adjusted according to the actual air quality in the car. For the relatively harsh car environment, the above ventilation methods are often difficult to quickly replace the air in the car.
