Example Embodiment

[0013] The present invention will be further explained below in conjunction with the drawings.

[0014] Such as figure 1 As shown, the noise reduction and ventilation structure of an elevator car according to the present invention includes a car body 1, a fan 2 is provided on the top of the car body 1, and the fan 2 is connected to a power source. The top wall, the left side wall, the right side wall and the rear side wall are all provided with a sound insulation cotton layer 3. The left side wall, the right side wall and the rear side wall of the box body 1 are all provided with exhaust ports 1-1, One end of the air port 1-1 is connected with a three-way joint 5, the top end of the three-way joint 5 is connected with an upper check valve 61, and the bottom end of the three-way joint 5 is connected with a lower check valve 62. When the elevator is ascending, the air resistance causes the upper one-way valve 61 to be disconnected from the three-way joint 5, and the wind discharge...

Abstract

The invention relates to the technical field of the elevator industry, in particular to a noise reduction and ventilation structure of an elevator car. The noise reduction and ventilation structure comprises a car body, the top of the car body is provided with a fan, the top wall, the left side wall, the right side wall and the rear side wall of the outside of the car body are respectively provided with a soundproof cotton layer, the left side wall, the right side wall and the rear side wall of the car body are respectively provided with an exhaust port, one end of each exhaust port is connected with a tee joint, the top end of each tee joint is connected with an upper one-way valve, and the bottom end of each tee joint is connected with a lower one-way valve. When the noise reduction and ventilation structure is used, the top wall, the left side wall, the right side wall and the rear side wall of the outside of the car body are respectively provided with one soundproof cotton layer, by means of the one-way valves, convection between air in the tee joints and air in the car body is formed, noise in the car body is greatly lowered, and ventilation performance of the car body is improved. The noise reduction and ventilation structure of the elevator car has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of the elevator industry, in particular to a noise reduction ventilation structure for an elevator car. Background technique [0002] When the elevator reciprocates up and down in the hoistway, the gas is instantly compressed sharply, and at the same time, the gas in the gap between the car body and the hoistway will suddenly increase in speed relative to the car body due to the sharp decrease in the flow area, resulting in a large The wind resistance, these resistance and the effect of the car, will produce wind resistance noise. In addition, the car is a closed space, and the air flow in the car is usually poor. Therefore, in order to ensure the comfort of the passengers in the elevator car, it is necessary to reduce noise and improve the ventilation performance of the elevator car. Contents of the invention [0003] The object of the present invention is to provide a noise-reducing ventilation structu...
