Description

Technical Field

[0001] This utility model relates to the field of elevators, and more specifically, to a ventilation structure and a passenger elevator. Background Technology

[0002] In existing technologies, the ventilation structure of passenger elevators usually adopts a fixed airflow direction design, which can meet the basic ventilation needs inside the elevator to a certain extent. By supplying or exhausting air into the elevator car, the air circulation inside the car is maintained, reducing the accumulation of odors and stale air, and providing passengers with a relatively fresh riding environment.

[0003] However, this fixed-direction ventilation structure has significant drawbacks, especially in cold weather. When the elevator is running, the airflow from the ventilation structure blows directly at the passengers in a fixed direction. Because the cold air directly irritates the body, passengers are prone to feeling cold and uncomfortable, affecting their riding experience. Therefore, we have proposed an improvement, namely a ventilation structure and a passenger elevator. Utility Model Content

[0004] The utility model provides a ventilation structure, including a ventilation fan. The outlet of the ventilation fan is provided with a connector. The connector is connected to two support pipes. The two support pipes are rotatably connected to a ventilation pipe through a sealed bearing. The ventilation pipe has a ventilation outlet.

[0005] As a preferred technical solution of this application, the connector includes a first connecting pipe disposed at the air outlet of the ventilation fan, the first connecting pipe being connected to a tee pipe, the tee pipe being connected to two conveying pipes, and one end of each of the two conveying pipes being connected to two support pipes respectively.

[0006] As a preferred technical solution of this application, a limiting member is provided between the outer surface of the support tube and the ventilation tube, and the limiting member is used to limit the ventilation tube.

The air outlet of the ventilation fan 2 is provided with a connector, which is connected to two support pipes 204. The two support pipes 204 are rotatably connected to a ventilation pipe 205 through a sealed bearing. The ventilation pipe 205 has a ventilation outlet 206. The ventilation pipe 205 is rotatable. Rotating the ventilation pipe 205 can adjust the orientation of the ventilation outlet 206, thereby adjusting the air outlet direction. In cold seasons, the ventilation outlet can be adjusted to not blow directly towards passengers, avoiding the discomfort caused by cold air blowing directly on passengers. In hot seasons, the air outlet can be directed towards passengers, thereby making passengers feel cool and improving the passenger riding experience in the elevator.

[0027] Furthermore, the connecting component includes a first connecting pipe 201 located at the air outlet of the ventilation fan 2. The first connecting pipe 201 is connected to a tee pipe 202, and the tee pipe 202 is connected to two conveying pipes 203. One end of each of the two conveying pipes 203 is connected to two support pipes 204. The first connecting pipe 201, the tee pipe 202, and the conveying pipes 203 cooperate to transmit the airflow from the ventilation fan 2 to the ventilation pipe 205, and then the airflow is discharged from the ventilation outlet 206 for ventilation.

[0028] Furthermore, a limiting component is provided between the outer surface of the support pipe 204 and the ventilation pipe 205. The limiting component is used to limit the ventilation pipe 205, thereby fixing the position of the ventilation pipe 205.

[0029] Furthermore, the limiting component includes a fixing ring 207 fixedly sleeved on the outer surface of the support tube 204. The inner wall of the fixing ring 207 is rotatably connected to the outer surface of the ventilation tube 205. A fastening bolt 208 is provided on the fixing ring 207. One end of the fastening bolt 208 passes through the fixing ring 207 and abuts against the outer surface of the ventilation tube 205. When the fastening bolt 208 is loosened, the ventilation tube 205 can be rotated. When the fastening bolt 208 is tightened, the position of the ventilation tube 205 can be fixed.

[0030] Furthermore, the air inlet of the ventilation fan 2 is equipped with a filter element, which is used to reduce dust entering the ventilation fan 2.

[0031] Furthermore, the filter element includes a support ring 209 bolted to the air inlet of the ventilation fan 2, and a filter screen 210 installed inside the support ring 209. The filter screen 210 is used to filter the air entering the ventilation fan 2 to reduce the entry of dust.

[0033] Furthermore, the elevator car 1 is provided with ventilation holes 101, which are distributed on the lower part of the side wall of the elevator car 1, forming an air convection path with the ventilation outlet 206 to achieve ventilation.

[0034] Furthermore, the elevator car 1 is also equipped with auxiliary components; the auxiliary components include two connecting rods 102 installed on the inner wall of the elevator car 1, and a handrail 103 is fixedly connected between the two connecting rods 102 for passengers to hold when riding.

[0035] The ventilation structure and passenger elevator provided by this utility model are used as follows:

[0036] When loosening the fastening bolt 208 and rotating the ventilation pipe 205, adjust the position of the ventilation outlet 206 according to the actual situation. In cold seasons, the ventilation outlet 206 should be directed downwards, while in hot seasons, it should be directed towards the passengers. After adjustment, tighten the fastening bolt 208 to fix the position of the ventilation pipe 205. The ventilation fan 2, through the first connecting pipe 201, the three-way pipe 202 and the conveying pipe 203, can deliver air to the ventilation pipe 205, and the air is discharged from the ventilation outlet 206 for ventilation.
