JPH07315731A - Ventilation device for machine room of elevator - Google Patents

Abstract

PURPOSE:To provide a ventilation device formed by fitting a gallery in the wall of an elevator machine room which can make ventilation of the machine room whenever it is necessary without risk of rainwater intrusion and influence of the wind direction by furnishing a wind/rain shield member on the outside of the gallery. CONSTITUTION:A wind/rain shield member includes a frame 9A fixed to the exterior wall surface of a wall 2A, the first plates 9B which are thin and long in the vertical direction and laid with a gap 10 reserved in between and whose top and bottom are fixed to the frame 9A, and members which are arranged opposing to the gap 10 while positioned behind the first plates 9B (nearer the gallery 8) and have an inverted channel shaped horizontal section and whose top and bottom are fixed to the frame 9A. When wind and/or rain are blown to the wall 2A, they pass the gap 10, run against the second plates 9C, and attach to the wall surface with the second plates 9C to flow down, and the winds are mitigated by collision with the second plates 9C.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator machine room ventilation system.

[0002]

2. Description of the Related Art Conventionally, as an apparatus of this kind, an actual flatbed 1
As described in Japanese Patent Laid-Open No. 72565, the gallery for taking in outside air is opened and closed, and the gallery is opened when the ventilation fan is in operation, and when the ventilation fan is stopped,
It is proposed that the gallery be interlocked to keep it closed.

[0003]

In the above-mentioned conventional apparatus, when the wind blows toward the galleries, rain may directly blow on the galleries and enter the machine room. Therefore, the machine room may not be ventilated depending on the wind direction.

An object of the present invention is to provide an elevator machine room ventilator which is capable of ventilating the machine room at any time when there is no risk of rain intrusion and is not affected by wind direction during wind and rain. Especially.

[0005]

SUMMARY OF THE INVENTION The above object is achieved by disposing a wind and rain shelter member outside the gallery in an elevator for a machine room of an elevator in which a gallery is attached to a wall of an elevator machine room.

[0006]

With the above structure, even if the rain blows toward the galleries, the rain first collides with the wind and rain shelter member to remove the rain and weaken the wind, so that the rain and wind reach the galleries as they are. There is little to do.

Therefore, even if the wind direction during wind and rain is such that it directly blows against the galleries, the wind and rain will not enter the machine room, and the machine room can be ventilated whenever necessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In the figure, 1 is an elevator hoistway formed over a plurality of floors of a building, 2 is a machine room formed at the top of the hoistway 1, and 3 is an elevator control installed in the machine room 2. A board 4 is a pulley of an elevator hoisting machine installed in the machine room 2, 5 is a deflector wheel installed in the machine room 2, and 6 is a balance weight (not shown) of a car (not shown) of the elevator. No.) and the pulley 4
Also, the main rope 7 hung on the deflecting vehicle 5, and 7 are ventilations (exhaust air) mounted above the wall 2A of the machine room 2.
A fan, 8 is a louver provided at a lower position on a wall 2A of the machine room 2 on the side opposite to the ventilation fan 7, and 9 is a wind and rain shielding member provided outside the louver 8.

The wind and rain shelter member 9 is shown in detail in FIGS. 1 and 2.
As shown in FIG. 9, the frame 9A fixed to the outer wall surface of the wall 2A
And the upper and lower ends are fixed (welded) to the frame 9A, and the gap 1
A plurality of first plates 9B elongated in the up-down direction arranged at intervals of 0, and arranged behind the first plate 9B (close to the gallery 8) so as to face the gap 10 and have a horizontal cross section of an inverse shape. Since it is in the shape of a letter, and the upper and lower ends are fixed (welded) to the frame 9A, when wind and rain is blown toward the wall 2A, after the wind and rain passes through the gap 10, The second plate 9C collides, adheres to the wall surface of the second plate 9C and flows downward, and the wind is softened by the collision with the second plate 9C.

As a result, even if the weather is strong
It is possible to suppress the invasion into the machine room 2 through the passage and to ventilate the machine room 2 even when the weather is heavy.

Further, since the horizontal cross-sectional shape of the second plate 9C is an inverted U-shape, rain attached to the second plate 9C is prevented from being blown away by the wind when falling along the wall surface. It is possible to prevent the rain attached to the second plate 9C from scattering again in the wind and flowing into the gallery 8.

In the above embodiment, the case where the first and second plates are combined has been described, but the second plate 9C may be flat.

Also, one or a plurality of punching plates (plates provided with a large number of pores of several millimeters)
May be attached to the outside of the gallery 8 at a distance from the gallery 8.

In these embodiments, as compared with the first embodiment, the structure can be more simplified, and the water from the upper gallery 8 can be prevented.

[0016]

As described above, according to the present invention, even if rain blows toward the galleries, the wind and rain first collide with the wind and rain shelter member to remove the rain and weaken the wind. Rain and wind rarely reach as they are.

Therefore, even if the wind direction at the time of wind and rain is such that the wind blows directly against the galleries, the wind and rain do not enter the machine room, and the machine room can be ventilated whenever necessary.
