Negative pressure type air purifying lift car

Abstract

The invention provides a negative pressure type air purifying lift car. At least one first ventilation opening is formed in the lower portion of a car wall, and a negative pressure type fan is arranged on a car top or a fourth ventilation opening is formed in the car top. The negative pressure type fan (7) is arranged at the lower portion of the car wall (2), and a negative pressure air outlet inthe top of a negative pressure box (9) is connected with the negative pressure type fan (7). An air filter (14) is arranged at the position of the first negative pressure air inlet in the bottom of the negative pressure box (9). An ultraviolet lamp (12) is installed on the inner wall of the negative pressure box (9). The negative pressure type fan (7) discharges lift car interior air filtered, disinfected and sterilized by the negative pressure box (9) into a well, negative pressure can be generated in the lift car, lift car external air is sucked in through the first ventilation opening or issucked through an opening car door (5), and therefore directional air circulation from bottom to top is formed in the air purifying lift car. By means of the negative pressure type air purifying liftcar, fast air exchange between the lift car and a lift hall and between the lift car and the well is achieved, the manner that air is fed from the periphery of the lower portion of the car wall and discharged from the car top or the air is fed from the car top and discharged from the lower portion of the car wall is adopted, and directional flowing from bottom to top or from top to bottom is formed; and the purifying efficiency is improved, the quality of the air in the lift car and the quality of the air in the well are effectively improved, and the probability of cross infection among passengers in the car is effectively lowered.

Description

Technical field [0001] The invention relates to the technical field of elevator cars, in particular to a negative pressure type air purification car. Background technique [0002] In relatively closed public places such as hospitals, hotels, large shopping malls, commercial houses, and office buildings, due to the large number of migrants, harmful pollutants such as bacteria and viruses are likely to spread among people and cause cross-infection. In addition, general pollutants such as smoke, haze, dust, peculiar smell, and dirt brought in when people enter and exit public places can also cause different degrees of harm to the human body. [0003] As a transfer bearing device between floors, elevators are widely used in large public places. As the number of floors continues to increase, elevators have become an indispensable part of high-rise buildings. [0004] The elevator in the prior art mainly uses the elevator car as a means of carrying people. The car is often crowded with pe...

AI Technical Summary

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a negative-pressure air-purifying car. The negative pressure inside the car can solve the problem that the air cannot be exchanged quickly between the car and the shaft or waiting hall. , The air in the car and the shaft cannot be efficiently purified, leading to technical problems such as the risk of cross-infection of the car occupants
