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

Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] An elevator with air exchange function provided in this embodiment includes a car and a shaft, and an air convection device is installed in the car.
[0026] The air convection device includes an exhaust device and an air supply device.
[0027] Such as figure 1 As shown, the ventilation device 1 includes: a first air inlet 11 , a first air outlet 12 , a first motor 13 , a first impeller 14 , a first casing 15 and a filter layer 18 . The filter layer 18 is disposed between the first air inlet 11 and the first impeller 14 . The first motor 13 is connected to the first impeller 14 and arranged in the first casing 15, the first air inlet 11 is located on the side of the first impeller 14, and the first air outlet 12 is located on the first Below a motor 13,...

The invention provides an elevator with an air exchange function, including a car and a hoistway. An air convection device is installed in the car. The air convection device includes an air extraction device and an air supply device; the air extraction device is installed on the upper part of one side of the car. One air inlet faces the car door, the first air outlet faces the bottom of the car; the air supply device is installed on the upper part of the other side of the car, the second air inlet faces the bottom of the car, and the second air outlet faces the car door. The elevator with air exchange function provided by the present invention draws the air outside the hall into the car through the ventilation device, and the air supply device draws the air in the car out of the hall, thereby strengthening the convection between the air in the car and the air outside the hall. , comprehensively improving the quality of the air in the car; in addition, the exhaust device is provided with a filter layer, through which the air is filtered and purified, further improving the quality of the air in the car.
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 purif...
