Air-purifying elevator car roof

Abstract

The invention discloses an air-purifying elevator car roof, comprising a roof platform positioned above and a suspended ceiling layer positioned below; the roof platform and the suspended ceiling layer are peripherally fixedly connected through a cover plate; the suspended ceiling layer is provided with an air outlet and an air inlet; the air outlet and the air inlet are positioned respectively at two ends of the suspended ceiling layer; a vent duct is formed between the roof platform and the suspended ceiling layer; the vent duct at one end is connected with the air inlet of the suspended ceiling layer and at the other end is connected with an air purifier; the air outlet of the suspended ceiling layer is connected with a fan through a fan duct. The vent duct between the roof platform and the suspended ceiling layer enables air to circulate in a car; the combination of the air purifier and the fan enables effectively improved air quality in the car, removal of germs and other harmful substances and removal of bacteria and odors.

Description

technical field [0001] The invention relates to an elevator car top, in particular to an elevator car top with air purification function. Background technique [0002] At present, air purification technology is relatively mature. Through negative ions, ionization dust collectors and other means, air purifiers can effectively eliminate bacteria and odors, remove pollutants in the air, and are small in size. However, the effect of air purification in the elevator car is not satisfactory, and the ceiling structure is not designed for air purification requirements. [0003] Chinese patent document CN202080794U discloses a medical elevator car, through which a filter screen is set through the air inlet, but the original bacteria and pollutants in the car cannot be effectively removed. A medical elevator sterilizing device disclosed in Chinese patent document CN103771230A can only sterilize the car when the elevator is idle, and it is most necessary to purify the air when the flo...

Problems solved by technology

However, the effect of air purification in the elevator car is not satisfactory, and the ceiling structure is not designed for air purification requirements

[0003] Chinese patent document CN202080794U discloses a medical elevator car with a filter installed through the air inlet, but the original bacteria and pollutants in the car cannot be effectively removed

A medical elevator sterilization device disclosed in Chinese patent document CN103771230A can only sterilize the car when the elevator is idle, and it is most necessary to purify the air when the flow of people is the largest, but the purification process cannot be carried out

[0004] The air cleaning device disclosed in Chinese patent document CN101554555A is used in the elevator bridge room. Although it is equipped with settings such as air outlet and return air, the overall volume of the equipment is relatively large, which is not convenient for use in elevators; and the distance between the air outlet and the air return port is relatively large. Closely, the clean air blown out of the air outlet fails to circulate effectively in the car and returns from the air return port; the air in the car far away from the equipment cannot play an evolutionary role, and the actual effect is greatly reduced

For large cars, equipped with this kind of air purification equipment can not play the role of air purification at all

[0006] Moreover, equipped with air purification equipment with air outlet and return air, there are great limitations on the design of the ceiling, which not only takes up space, but also requires a large area on the ceiling to cooperate with the installation and use of equipment, so many ceiling styles cannot accomplish
