An energy-saving ventilated elevator

Abstract

The invention discloses an energy-saving, ventilated and ventilated elevator, which comprises an elevator outer shell, an elevator inner shell, a pulley seat and pulleys, an elevator inner shell is installed inside the elevator outer shell, an elevator outer shell and an elevator inner shell There is a ventilation channel between them, an extrusion plate is slidably connected to the top of the liquid storage chamber, and a fixing plate is arranged between the two chutes. The invention drives the pulley to rotate when the elevator rises and falls, and uses the rotation of the pulley to drive the rotation of the first blade and the second blade, so that the outside air is introduced into the elevator and the elevator's internal air is introduced into the outside, thereby improving the circulation of the air inside the elevator , and can change the ventilation volume of the elevator car according to the number of passengers in the elevator car, improve the air quality of the elevator car, and at the same time filter the dust in the air entering the elevator, and the air entering the elevator can drive the third The fan blade rotates to make the brush on the second rotating shaft clean the dust on the dust filter 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
