Elevator with air exchange function

Abstract

The invention provides an elevator with an air exchange function. The elevator comprises an elevator car and a shaft. An air convection device is mounted in the elevator car and comprises an air pumping device and an air supply device; the air pumping device is mounted on the upper portion of one side of the elevator car, a first air inlet faces an elevator car door, and a first air outlet faces the bottom of the elevator car; and the air supply device is mounted on the upper portion of the other side of the elevator car, a second air inlet faces the bottom of the elevator car, and a second air outlet faces the elevator car door. According to the elevator with the air exchange function, air outside a hall is pumped into the elevator through the air pumping device, air in the elevator car is pumped out of the hall through the air supplying device, convection of the air in the elevator car and the air outside the hall is enhanced, and the quality of the air in the elevator car is improved omni-directionally; and in addition, the air pumping device is provided with a filter layer, and the air is filtered and purified by the filter layer, so that the quality of the air in the elevatorcar is further improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator with an air exchange function. Background technique [0002] Elevators are widely used in middle and high-rise buildings. As a special means of transportation, elevators have problems such as small space, personnel density, and large flow. When passengers take the elevator, the car is in a closed state, and the air in the car is difficult to convect with the outside world. Passengers breathe in the car, which makes the air quality in the car worse, oxygen decreases, and carbon dioxide increases. The air in the car can convect with the outside world only when the car door is opened when passengers are getting on and off. It is difficult to restore the air quality in the car. [0003] At present, technicians install an air purification device in the car to filter and purify the air in the car, thereby improving the quality of the air. However, this kind of air p...

Problems solved by technology

When passengers take the elevator, the car is in a closed state, and the air in the car is difficult to convect with the outside world. Passengers breathe in the car, which makes the air quality in the car worse, oxygen decreases, and carbon dioxide increases. The air in the car can convect with the outside world only when the car door is opened when passengers are getting on and off. Difficulty restoring air quality inside the car

[0003] At present, technicians install an air purification device in the car to filter and purify the air in the car, thereby improving the air quality, but this kind of air purification device has high cost, large space, and requires regular replacement of the filter element

In addition, the air purification device can only purify the air in the car, and has a single function. It can only kill bacteria or remove formaldehyde, VOC, etc., and it is difficult to change the content ratio of oxygen and carbon dioxide in the air in the car.

Furthermore, the air in the elevator is frequently in the state of weightlessness and overweight, and its airflow is very unstable, which makes it difficult for the air in the elevator to be purified evenly and in a full range
