Air storage type elevator car device and control method

Abstract

The air storage type elevator car device is provided with a car body, an air storage and air supply assembly, a spraying assembly, an exhaust assembly and a control system, the air storage and air supply assembly is arranged at the top of the car body and provided with an air inlet fan, an air compressor and a pressure air storage tank, and the air inlet fan supplies air to the air compressor; the air compressor fills pressure air into the pressure air storage tank, the pressure air storage tank conveys clean air into the lift car, the spraying assembly is used for spraying a disinfectant to the lift shaft, and the exhaust assembly is used for sucking out turbid air in the lift car. The control system controls the air storage and supply assembly and the exhaust assembly to act jointly so that the interior of the car can be in a negative pressure state when the car door is closed. The negative pressure state of the lift car can be achieved, air is stored in advance through the air storage and air supply assembly, the air is disinfected in the storage period, and meanwhile disinfection and sterilization of a shaft are achieved.

Description

technical field [0001] The invention belongs to the technical field of elevator car equipment, and in particular relates to a gas storage type elevator car device and a control method thereof. Background technique [0002] The car-type elevator is a place with a small and closed interior space. The air flow in the elevator car is poor. The daily flow of ordinary elevators is very large. The polluted car will cause passengers to have the risk of cross-infection, while some special occasions Elevators, such as medical institutions, biological research institutions, and pharmaceutical institutions, have higher requirements on the air quality of elevators, and disinfection must be done to prevent the spread of germs. The traditional car disinfection mainly adopts spraying disinfectant, the labor intensity of the operators is high, and the comfort of the passengers is average. The emergence of negative pressure elevators can solve the problem of cross-infection in the car to a ce...
