Embodiment approach 1

[0037] figure 1 It is a perspective view showing a part of the elevator according to Embodiment 1. A frame-shaped car frame 2 that supports the car room 1 is provided around the car room 1 that moves up and down in the hoistway. Ropes 3 for suspending the car room 1 are fixed to the car frame 2, and the car room 1 is raised and lowered in the up and down direction by a traction machine. In Embodiment 1, for the purpose of reducing the noise in the car interior, the streamlined ventilation blocking member 4 is arranged at least one of the upper and lower sides in the ascending and descending direction of the car chamber 1 . The ventilation blocking member 4 is a member that exhibits resistance to the passing airflow passing through the member when the elevator ascends and descends.

[0038] figure 2 An example of the ventilation blocking member 4 is shown. and, image 3 showing along figure 1 The X-X section shown is the sectional view obtained by cutting the elevator, ...

Embodiment approach 2

[0056] Figure 10 It is a schematic cross-sectional view showing an elevator according to Embodiment 2. In the second embodiment, in addition to the car room 1 raised and lowered in the hoistway, the car frame 2 supporting the car room 1, the rope 3 for lifting the car room 1 and the car frame 2, and the dragging In addition to the engine, an L-shaped ventilation blocking member 4 having a ventilation opening 9 arranged at least one of the upper and lower sides of the car chamber 1 is added. Specifically, a ventilation blocking member 4 including a flat portion provided with a plurality of ventilation openings 9 and a plate-shaped eaves 7 extending perpendicularly to the flat portion is added.

[0057] Figure 11 An example of the ventilation blocking member 4 is shown. and, Figure 12 showing along Figure 10 The Z-Z section shown is a cross-sectional view obtained by cutting the elevator. The ventilation blocking member 4 has an L-shape, and a eave portion 7 protruding...

Embodiment approach 3

[0060] Figure 13 It is a schematic cross-sectional view showing an elevator according to Embodiment 3. In the third embodiment, in addition to the car room 1 raised and lowered in the hoistway, the car frame 2 supporting the car room 1, the rope 3 for raising and lowering the car room 1 and the car frame 2, and the dragging In addition to the lead machine and the ventilation blocking member 4 with the ventilation opening 9 disposed on the upper and lower sides of the car room 1, such as Figure 13 As shown, a ventilation blocking member 4 arranged on the upper and lower sides of the car chamber 1 is added.

[0061] By providing the ventilation blocking members 4 on the upper and lower sides of the car room 1, not only the car room noise can be reduced when the car room 1 is raised, but also the car room noise can be reduced when the car room 1 is lowered.

Abstract

An elevator is provided. In the prior art, the windshield covering the ceiling or the floor has a high cost due to the complicated shape of the whole body, the processing cost and the installation cost, and the present invention can only be applied to some of the problems in the advanced model. In addition, since the entire body is attached in such a manner as to cover the ceiling or the ground, there is a problem that the maintenance is deteriorated. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an elevator which improves the ratio of the effect to the cost and reduces the noise in the car room. The elevator of the present invention is provided with at least one of the upper and lower portions of the car room with a ventilation damper having a vent, wherein the car room is raised and lowered in the hoistway. And an air permeable member is disposed in the vicinity of the vent block.

Description

technical field [0001] The present invention relates to an elevator for transporting at least one of people and goods. Background technique [0002] In an elevator, a car chamber for transporting at least one of people and goods moves up and down in a hoistway. When the lifting speed of the car room increases, noise is generated due to the turbulence of the air flow, and comfort in the car room may be hindered by the noise. In order to maintain comfort in the car interior, a technique has been proposed to reduce noise in the car interior by arranging air conditioning bodies above and below the car chamber to suppress turbulence in the air flow (for example, Patent Document 1). [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2003-118954 [0004] Patent Document 1 proposes a technique in which an arc-shaped air rectifying body is connected to the upper and lower surfaces of a rectangular parallelepiped cage, and the edge of the rectangular parallelepiped cage supp...
