Description

Device for automatic exhaust by elevator car running

technical field

The utility model relates to a ventilation device, in particular to a device for automatically exhausting air when an elevator car is running.

Background technique

Usually, the ventilation device of the elevator car is relatively airtight, which makes it difficult for the elevator car to communicate with the outside air. Entering the elevator car is entirely by the brief moment the elevator car door opens. During the peak hours of elevator operation, when there are many passengers, the air in the elevator car is very turbid, which makes people feel very uncomfortable especially in summer.

Contents of the invention

Aiming at the deficiencies in the prior art, the utility model provides a device for exhausting the car by using the negative pressure generated in the air guide tube when the elevator is running.

The purpose of this utility model is achieved in the following way: a device for automatic exhausting by the operation of the elevator car, which includes an exhaust device panel provided with an upper air outlet, a lower air outlet and a first positioning hole, and an upper shaft The sleeve and the lower rotating shaft sleeve are respectively fixed above the upper air outlet and the lower air outlet, and the upper windshield is provided with an upper flexible rubber strip and an upper windshield rotating shaft, and the upper windshield rotating shaft is sleeved on the upper windshield. In the shaft sleeve; the lower windshield is provided with a lower flexible rubber strip and a lower windshield shaft, and the lower windshield shaft is sleeved in the lower shaft sleeve; the upper air duct and the lower air duct are on the same side. The rotating shaft of the upper windshield is sleeved in the upper rotating shaft sleeve, and the two are in a clearance fit; the rotating shaft of the lower windshield is sleeved in the lower rotating shaft sleeve, and the two are in a clearance fit; the device panel and the car wall are fixed together, An air outlet and an air inlet are arranged on the car wall plate, the air inlet arranged on the car wall plate is at the top, and the air outlet is at the bottom, and the distance between the two closest sides is greater than 1500mm.

When the elevator runs upwards, the air pressure in the lower air duct is lower than the air pressure in the elevator car, the lower windshield is opened, and the positive pressure air in the car is sucked out of the car through the lower air outlet. The positive-pressure airflow formed in the cylinder forces the upper windshield to close, so that the positive-pressure airflow outside the car can only enter the elevator car through the air inlet installed on the car wall, realizing automatic exhaust and ventilation of the elevator car.

When the elevator is running downwards, the air pressure in the upper air duct is lower than the air pressure in the elevator car, the upper windshield is opened, and the positive pressure airflow in the car is sucked out of the car through the upper air outlet. The positive-pressure airflow formed in the air duct forces the lower windshield to close, so that the positive-pressure airflow outside the car can only enter the elevator car through the air inlet above the car wall, realizing automatic exhaust and ventilation of the elevator car .

Compared with the prior art, the utility model has the advantages of: 1. The upper and lower exhaust ducts of the device can respectively form low air pressure when the elevator goes down or up, and the air in the elevator car is discharged; when the air pressure in the elevator car When the air pressure outside the elevator car is lower than the air pressure outside the elevator car, the external air can enter the elevator car through the air inlet arranged on the car wall, so as to realize the purpose of air flow and freshness in the elevator car. 2. The air inlet of this device is set above the car wall. Since the air inlet has no mechanical device, it can realize silent air intake; the movable part is set under the car wall relatively far from the ears of passengers, which can effectively Reduce the impact of the noise of the wind deflector opening or closing on the passengers. 3. Installing this device on an open sightseeing elevator car can also realize automatic ventilation of the elevator car.

Detailed ways

Below, the utility model is described in detail in conjunction with accompanying drawing and embodiment:

Fig. 1-Fig. 4 is an embodiment of the present utility model. As shown in the figure, a device for automatically exhausting air when the elevator car is running, it includes an exhaust device panel 1 provided with an upper air outlet 1c, a lower air outlet 1d and a first positioning hole 1a, and an upper shaft sleeve The cylinder 1b and the lower shaft sleeve 1e are respectively fixed above the upper air outlet 1c and the lower air outlet 1d, and the upper windshield 2 is provided with an upper flexible rubber strip 2b and an upper windshield shaft 2a, and the upper windshield The wind plate rotating shaft 2a is set in the upper rotating shaft sleeve 1b, and the upper air exhaust tube 3 is fixed on the side of the exhaust device panel 1 provided with the upper rotating shaft sleeve 1b; the lower windshield 5 is provided with a lower flexible rubber strip 5b and the lower windshield rotating shaft 5a, the lower windshield rotating shaft 5a is sleeved in the lower rotating shaft sleeve 1e, and the lower exhaust fan 4 is fixed on the side of the lower rotating shaft sleeve 1e on the exhaust device panel 1; the upper exhaust fan 3 is on the same side as the lower air duct 4; the upper air duct 3 and the lower air duct 4 are installed on the outside of the car wall plate 6; The device panel 1 and the car wall plate 6 are fixed together, and the car wall plate 6 is provided with an air outlet 6b and an air inlet 7, the air inlet 7 is at the top, and the air outlet 6b is at the bottom, and the distance between the two closest sides is greater than 1500mm.

The upper windshield rotating shaft 2a is sleeved in the upper rotating shaft sleeve 1b, and the two are in a clearance fit; the lower windshield rotating shaft 5a is sleeved in the lower rotating shaft sleeve 1e, and the two are in a clearance fit; the upper windshield 2 is on both sides When the air pressure is the same, it will naturally sag and block the upper air outlet 1c; when the air pressure on both sides of the lower windshield 5 is the same, it will naturally sag and block the lower air outlet 1d.
