Energy-saving ventilation type elevator

Abstract

The invention discloses an energy-saving ventilation type elevator which comprises an elevator outer shell, an elevator inner shell, a pulley seat and a pulley. The elevator inner shell is installed in the elevator outer shell, a ventilation channel is formed between the elevator outer shell and the elevator inner shell, an extrusion plate is slidably connected to the top of a liquid storage cavity, and a fixing plate is arranged between two sliding grooves. According to the energy-saving ventilation type elevator, the pulley is driven to rotate when the elevator ascends and descends, and a first fan blade and a second fan blade are driven to rotate through rotation of the pulley, so that outside air is guided into the elevator and air in the elevator is guided into the outside, and circulation of the air in the elevator is improved; and the ventilation quantity of an elevator car can be changed according to different numbers of passengers in the elevator car, the air quality of the elevator car is improved, meanwhile, dust in air entering the elevator can be filtered, and the air entering the elevator can drive a third fan blade to rotate, so that a brush on a second rotating shaft sweeps the dust on a dust filtering net.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an energy-saving ventilation type elevator. Background technique [0002] In recent years, with the development of high-rise buildings, the use of elevators has become one of the indispensable equipment for people. Its main function is to transport passengers at vertical heights. Running speed and safety performance are two important performance indicators of elevators. However, with the development of the economy and the continuous improvement of people's living standards, people have higher and higher requirements for the comfort and air quality of the elevator car, so the ventilation device inside the car is particularly important. [0003] Most of the existing elevator cars are ventilated by exhaust fans, and some high-end elevator cars are equipped with air-conditioning systems. The cars equipped with air-conditioning systems are usually airtight, but the ventilation is re...

Problems solved by technology

[0003] Most of the existing elevator cars are ventilated by means of exhaust fans, and some high-end elevator cars are equipped with air-conditioning systems. The cars equipped with air-conditioning systems are usually closed, but the ventilation is relatively slow, and it cannot be used when the number of people increases or When it is reduced, it will achieve a kind of effect of drafting and entering the wind, which will easily cause the temperature of the elevator car to be high and the ventilation effect to be poor. At the same time, the existing elevator car cannot change the air volume according to the number of passengers in the elevator car
