Embodiment 1 FIG.
FIG. 1 is a sectional view showing an elevator apparatus according to this embodiment.
The elevator apparatus according to this embodiment includes a car 2 provided in the hoistway 1 so as to be able to be raised and lowered, a rope 3 having one end connected to the car 2, and provided in the hoistway 1. A counterweight 4 connected to the end and moving up and down in the reverse direction in conjunction with the up and down movement of the car 2 is provided.
The elevator apparatus includes a drive device 5 provided around the hoistway 1 and wound with a rope 3, a control device 6 connected to the drive device 5 and controlling the drive of the drive device 5, An upper end portion is provided to face the driving device 5, and a lower end portion includes a duct 7 extending downward along the side wall of the hoistway 1.
When the driving device 5 is driven by the control of the control device 6, the car 2 and the rope 3 are moved up and down via the rope 3.

ダクト７は、昇降路１内の余剰スペースを利用して配置されており、ダクト７の下端部には、内部に送風機８が設けられている。
これにより、送風機８が駆動することで、ダクト７の下端部に空気が送り込まれ、ダクト７の上端部から空気が送り出される。
なお、送風機８は、ダクト７の内部に限らず、外部であってもよい。この場合、駆動することでダクト７の下端部に空気が送り込まれてダクト７の上端部から空気が送り出されるように、ダクト７の近傍に送風機８が配置される。 The duct 7 is disposed using an excess space in the hoistway 1, and a blower 8 is provided inside the duct 7 at the lower end portion.
Thereby, when the blower 8 is driven, air is sent to the lower end portion of the duct 7, and air is sent out from the upper end portion of the duct 7.
The blower 8 is not limited to the inside of the duct 7 but may be outside. In this case, the blower 8 is arranged in the vicinity of the duct 7 so that the air is sent to the lower end portion of the duct 7 and the air is sent out from the upper end portion of the duct 7 by driving.

昇降路１の外側には、各階に乗場が形成されており、ダクト７の下端部は、最上階乗場１ａ付近の高さまで延びている。
最上階乗場１ａの空気は、建物の冷房によって低い温度となっており、最上階乗場１ａ付近の昇降路１内の空気は、最上階乗場１ａの空気の温度の影響を受けるので、低い温度となっている。
したがって、ダクト７の下端部付近の空気は、駆動装置５付近の空気と比べて、低い温度となっている。
なお、ダクト７は、最上階乗場１ａ側に配置されることが好ましい。この場合、ダクト７の下端部付近の空気の温度が、最上階乗場１ａの空気の温度にさらに近づくので、ダクト７の下端部には、さらに低い温度の空気が送り込まれる。 A landing is formed on each floor outside the hoistway 1, and the lower end of the duct 7 extends to a height near the top floor landing 1a.
The air in the top floor hall 1a is at a low temperature due to cooling of the building, and the air in the hoistway 1 near the top floor hall 1a is affected by the temperature of the air in the top floor hall 1a. It has become.
Therefore, the air near the lower end of the duct 7 has a lower temperature than the air near the drive device 5.
In addition, it is preferable that the duct 7 is arrange | positioned at the top floor hall 1a side. In this case, the temperature of the air in the vicinity of the lower end of the duct 7 is closer to the temperature of the air in the uppermost landing 1a, so that air having a lower temperature is sent into the lower end of the duct 7.

駆動装置５の駆動によりかご２が昇降すると、かご２が通過する昇降路１内の空気は攪拌されるので、かご２が最上階乗場１ａに到達したときには、最上階乗場１ａ付近の昇降路１内の空気は、昇降路１内の下側の空気と混合されて、さらに低い温度になる。
したがって、かご２が昇降して最上階乗場１ａに到達したときのダクト７の下端部付近の空気は、かご２が昇降していないときの空気と比べて、さらに低い温度になる。
この状態で送風機８が駆動すると、この低い温度の空気が、ダクト７の下端部に送り込まれ、ダクト７の上端部から送り出される。
ダクト７の上端部から送り出されたこの低い温度の空気は、駆動装置５に衝突して、駆動装置５および駆動装置５の周囲を冷却する。 When the car 2 moves up and down by driving the driving device 5, the air in the hoistway 1 through which the car 2 passes is agitated. Therefore, when the car 2 reaches the uppermost landing 1a, the hoistway 1 near the uppermost landing 1a. The air inside is mixed with the air on the lower side in the hoistway 1 to reach a lower temperature.
Therefore, the air near the lower end of the duct 7 when the car 2 moves up and down and reaches the top floor landing 1a has a lower temperature than the air when the car 2 does not move up and down.
When the blower 8 is driven in this state, the low-temperature air is sent to the lower end portion of the duct 7 and is sent out from the upper end portion of the duct 7.
The low-temperature air sent out from the upper end of the duct 7 collides with the driving device 5 and cools the driving device 5 and the surroundings of the driving device 5.

ダクト７の上端部から送り出された空気が駆動装置５に衝突することで、駆動装置５の表面では強制対流熱伝達率が増加するので、駆動装置５の冷却効率が向上する。
ダクト７の上端部から送り出された空気が駆動装置５の周囲を冷却することで、駆動装置５全体を冷却する。 Since the air sent out from the upper end of the duct 7 collides with the driving device 5, the forced convection heat transfer coefficient increases on the surface of the driving device 5, and the cooling efficiency of the driving device 5 is improved.
The air sent out from the upper end of the duct 7 cools the periphery of the driving device 5, thereby cooling the entire driving device 5.

昇降路１内で発生した熱は上昇して昇降路１の頂部に移動するので、昇降路１の頂部が最も高温となる。
また、昇降路１の天井が建物の屋外に面している場合、昇降路１の天井には直射日光が照射されるので、昇降路１の頂部はさらに高温となる。
しかしながら、ダクト７および送風機８により、駆動装置５を冷却することができるので、駆動装置５を昇降路１の頂部に配置することができる。
これにより、昇降路１の省スペース化を図ることができる。 Since the heat generated in the hoistway 1 rises and moves to the top of the hoistway 1, the top of the hoistway 1 becomes the hottest.
In addition, when the ceiling of the hoistway 1 faces the outside of the building, the ceiling of the hoistway 1 is irradiated with direct sunlight, so that the top of the hoistway 1 is further heated.
However, since the drive device 5 can be cooled by the duct 7 and the blower 8, the drive device 5 can be disposed on the top of the hoistway 1.
Thereby, space saving of the hoistway 1 can be achieved.

また、駆動装置５以外の機器、例えば、制御装置６をダクト７の上端部に対向して配置することで、制御装置６および制御装置６の周囲を冷却することができるので、制御装置６は、駆動装置５と同様にして、昇降路１の頂部に配置することができる。
これにより、昇降路１の省スペース化をさらに図ることができる。 Further, by arranging the device other than the drive device 5, for example, the control device 6 so as to face the upper end of the duct 7, the control device 6 and the periphery of the control device 6 can be cooled. In the same manner as the driving device 5, it can be arranged on the top of the hoistway 1.
Thereby, the space saving of the hoistway 1 can further be achieved.

以上説明したように、この実施の形態に係るエレベータ装置によれば、駆動装置５の温度より低い温度の空気が、ダクト７の下端部に送り込まれ、ダクト７の上端部から送り出されて、駆動装置５に衝突するので、簡単な構成で、駆動装置５を冷却することができる。   As described above, according to the elevator apparatus according to this embodiment, air having a temperature lower than that of the drive device 5 is sent to the lower end portion of the duct 7 and sent from the upper end portion of the duct 7 to drive the air. Since it collides with the device 5, the drive device 5 can be cooled with a simple configuration.

また、ダクト７の下端部は、昇降路１に形成された最上階乗場１ａ付近の高さまで延びているので、最上階乗場１ａの空気により冷却された最上階乗場１ａ付近の昇降路１内の空気を駆動装置５に衝突させることができ、駆動装置５をさらに冷却することができる。   Moreover, since the lower end part of the duct 7 is extended to the height near the top floor landing 1a formed in the hoistway 1, the inside of the hoistway 1 near the top floor landing 1a cooled by the air of the top floor landing 1a. Air can be made to collide with the drive device 5, and the drive device 5 can be further cooled.

この実施の形態に係るエレベータ装置は、ダクト７の下端部が、かご２が最上階乗場１ａに到達したときの上端部の高さまで延びている。
かご２が上昇して最上階乗場１ａに到達すると、かご２の上端部付近の空気は、昇降路１内の下側の空気と混合されて、低い温度となる。
このとき、送風機８により、かご２の上端部付近の空気は、ダクト７の下端部に送り込まれ、ダクト７の上端部から送り出されて、駆動装置５に衝突するので、駆動装置５および駆動装置５の周囲を冷却する。
その他の構成は実施の形態１と同様である。 Embodiment 2. FIG.
FIG. 2 is a sectional view showing the elevator apparatus according to this embodiment.
In the elevator apparatus according to this embodiment, the lower end portion of the duct 7 extends to the height of the upper end portion when the car 2 reaches the top floor landing 1a.
When the car 2 rises and reaches the uppermost landing 1a, the air near the upper end of the car 2 is mixed with the lower air in the hoistway 1 and becomes a low temperature.
At this time, the air near the upper end portion of the car 2 is sent to the lower end portion of the duct 7 by the blower 8 and is sent out from the upper end portion of the duct 7 to collide with the drive device 5. Cool around 5.
Other configurations are the same as those in the first embodiment.

この実施の形態に係るエレベータ装置によれば、ダクト７の下端部が、かご２が最上階乗場１ａに到達したときの上端部の高さまで延びているので、ダクト７を小型化することができ、その結果、昇降路１内の他の機器の配置の自由度を向上させることができる。   According to the elevator apparatus according to this embodiment, the duct 7 can be downsized because the lower end of the duct 7 extends to the height of the upper end when the car 2 reaches the top floor landing 1a. As a result, the degree of freedom of arrangement of other devices in the hoistway 1 can be improved.
