Description

本発明は、エレベータかご内換気装置に関する。   The present invention relates to an elevator car ventilation device.

エレベータのかごは密閉された空間であり、この密閉された空間内に多数の利用者が搭乗する特殊な環境にある。このため、かご内を換気する換気装置は一般的な換気システムとは異なりエレベータのかご内の換気に特有の構造が必要である。   The elevator car is a sealed space, and is in a special environment in which a large number of users get on the sealed space. For this reason, the ventilator for ventilating the inside of the car requires a structure specific to the ventilation in the elevator car, unlike a general ventilation system.

従来のエレベータかご内換気装置は、図７に示すように、天井板１に照明構造体２を取り付けた天井３に設けられる。天井板１は照明構造体２が設けられた下面に対して上面側の周縁に沿って断面コ字状の枠体１ａを備え、この枠体１ａの内側に収納可能な換気装置４が所望位置に設けられる。   As shown in FIG. 7, a conventional elevator car ventilation device is provided on a ceiling 3 in which a lighting structure 2 is attached to a ceiling plate 1. The ceiling board 1 is provided with a frame body 1a having a U-shaped cross section along the peripheral edge on the upper surface side with respect to the lower surface on which the illumination structure 2 is provided, and the ventilation device 4 that can be stored inside the frame body 1a has a desired position. Is provided.

換気装置４は、図７のVIII−VIII線の断面図である図８に示すように、吸音材５を内側面に有するカバー６が、換気用ファン７を覆う構成を有している。図８に示すように、天井板１における換気装置４が設けられた箇所には、通気口１ｂが開口しており、天井板１の上に設置された換気装置４のカバー６の側面には外気吸排気口８が開口している。外気吸排気口８から換気用ファン７の回転により流入された外気はエレベータかご内に開口する通気口１ｂを介してかご内に供給されると共に、かご内の空気は換気用ファン７の回転により通気口１ｂから外気吸排気口８を介してエレベータの昇降路へと排気される。   As shown in FIG. 8, which is a cross-sectional view taken along the line VIII-VIII of FIG. 7, the ventilation device 4 has a configuration in which a cover 6 having a sound absorbing material 5 on the inner surface covers the ventilation fan 7. As shown in FIG. 8, a vent 1 b is opened at a place where the ventilation device 4 is provided on the ceiling panel 1, and the side surface of the cover 6 of the ventilation device 4 installed on the ceiling panel 1 is provided on the side surface. An outside air intake / exhaust port 8 is opened. The outside air that has flowed in from the outside air intake / exhaust port 8 due to the rotation of the ventilation fan 7 is supplied into the car through the vent 1b that opens into the elevator car, and the air in the car is rotated by the rotation of the ventilation fan 7. The air is exhausted from the vent 1b to the elevator hoistway through the outside air intake / exhaust port 8.

図７，図８に示すエレベータかごに設置された換気装置４は、昇降路内の外気とかご内の空気を換気用ファン７により強制的に吸排気させることにより、かご内の換気を行なっているが、換気装置４の駆動により発生する騒音や振動を吸収するための構造としては、カバー６の内面に吸音材５を設けることにより実現していた。   The ventilation device 4 installed in the elevator car shown in FIGS. 7 and 8 ventilates the car by forcibly sucking and exhausting the outside air in the hoistway and the air in the car by the ventilation fan 7. However, the structure for absorbing noise and vibration generated by driving the ventilation device 4 has been realized by providing the sound absorbing material 5 on the inner surface of the cover 6.

しかしながら、上述した従来のエレベータかご内換気装置は、外気吸排気口８が換気用ファン７の近傍に設けられているため、換気用ファン７を覆うカバー６の内壁面に吸音材５を設けていても、外気吸排気口８と天井板１の通気口１ｂとの間の距離が接近していることにより、吸音の効果が得られる距離が短くなってしまい充分な消音効果を得にくかった。   However, in the conventional elevator car ventilator described above, since the outside air intake / exhaust port 8 is provided in the vicinity of the ventilation fan 7, the sound absorbing material 5 is provided on the inner wall surface of the cover 6 that covers the ventilation fan 7. However, since the distance between the outside air intake / exhaust port 8 and the vent 1b of the ceiling plate 1 is close, the distance for obtaining the sound absorption effect is shortened, and it is difficult to obtain a sufficient silencing effect.

さらに、昇降路内を昇降する行程の長いエレベータではエレベータかごの昇降動作が高速となり、図８に示すように、天井板１の上面に衝突する空気がかごの上方で乱流９となって騒音１０を発生させ、この騒音１０が外気吸排気口８から換気用ファン７を伝いかご内１１に進入して、かご内１１の騒音を増加させる問題の一因となっている。また、乱流９は図８に示すように外気吸排気口８方向のみに発生するのではなく、天井板１を補強するための補強用リブ１ｃ方向に対しても発生するので、補強用リブ１ｃに衝突した乱流９が反射して騒音１０を増幅させて、いっそう大きな騒音を発生させる可能性もある。このような騒音はエレベータの利用者に不快感を与えることになるため、騒音対策を講じる必要がある。   Further, in an elevator with a long stroke in the hoistway, the elevator car is moved up and down at high speed, and as shown in FIG. 8, the air impinging on the upper surface of the ceiling plate 1 becomes turbulent flow 9 above the car and becomes a noise. 10, and this noise 10 enters the car 11 through the ventilation fan 7 from the outside air intake / exhaust port 8 and contributes to the problem of increasing the noise in the car 11. Further, the turbulent flow 9 does not occur only in the direction of the outside air intake / exhaust port 8 as shown in FIG. 8, but also occurs in the direction of the reinforcing rib 1c for reinforcing the ceiling plate 1, so that the reinforcing rib There is also a possibility that the turbulent flow 9 colliding with 1c is reflected to amplify the noise 10 and generate a larger noise. Such noise causes discomfort to the elevator user, so it is necessary to take measures against noise.

このような騒音対策の１つとして、特許文献１に開示された技術が提案されており、この提案によれば、かごの天井上部に換気用ファンから取り入れられる新鮮な空気をかご内に導通する通風ダクトと、低周波騒音低減用のアクティブ騒音制御手段とを設けて、対象となる騒音を検出してその波形を解析し、これと同音圧で逆位相の音波をアクティブスピーカから発振させて互いの音を相殺することにより通常の吸音材では低減しにくい低周波数の騒音を低減させている。
特許第２８９６２８６号公報 As one of such noise countermeasures, a technique disclosed in Patent Document 1 has been proposed. According to this proposal, fresh air taken from a ventilation fan is conducted into the upper part of the ceiling of the car. A ventilation duct and active noise control means for reducing low-frequency noise are provided, the target noise is detected and its waveform is analyzed, and sound waves with the same sound pressure and opposite phase are oscillated from the active speaker. By canceling out the noise, low-frequency noise that is difficult to reduce with a normal sound-absorbing material is reduced.
Japanese Patent No. 2896286

しかし、上述した特許文献１に開示された消音機能付きエレベータかご内換気装置は、消音機能を実現するために専用のアクティブ騒音制御装置を付加する必要がある。このため、エレベータかご換気装置の製造コストが高価になるという問題がある。   However, the elevator car ventilator with a silencing function disclosed in Patent Document 1 described above needs to add a dedicated active noise control device in order to realize the silencing function. For this reason, there exists a problem that the manufacturing cost of an elevator car ventilation apparatus becomes expensive.

また、特許文献１の提案とは別個に、図７，図８に示す従来のエレベータ換気装置において、かご内１１の天井板１の上に換気装置を設けるのではなく、図８に示したかご内１１の側面版１２に換気装置を取り付けることも考えられるが、側面版１２に通気口を開口させるため、側面版１２の一部に開口や段差等が生じてしまい、美観を損なうだけでなく意匠的にも好ましくないという問題がある。また、昇降路の内壁とかごとの間に充分な空間が確保されていない構造のエレベータにおいては、かご外部側面に換気装置を設置することができないという問題もある。   Separately from the proposal of Patent Document 1, in the conventional elevator ventilator shown in FIGS. 7 and 8, the car shown in FIG. 8 is not provided on the ceiling plate 1 in the car 11, but in the car shown in FIG. It is conceivable to attach a ventilator to the side plate 12 of the inner 11. However, since a vent is opened in the side plate 12, an opening or a step is generated in a part of the side plate 12, which not only impairs the beauty. There is a problem that it is not preferable in terms of design. Further, in an elevator having a structure in which a sufficient space is not secured between the inner wall of the hoistway and the car, there is also a problem that a ventilation device cannot be installed on the outer side of the car.

本発明は上記課題に鑑みてなされたものであり、低製造コストで外気吸排気口とかご内の通気口が近接することに起因するかご内の騒音の発生を抑制すると共にかご内の側面版の意匠的な美観を確保するエレベータかご内換気装置を提供することを目的とする。   The present invention has been made in view of the above problems, and suppresses the generation of noise in the car due to the close proximity of the outside air intake / exhaust port and the air vent in the car at a low manufacturing cost, and the side plate in the car. The purpose of the present invention is to provide an elevator car ventilation device that ensures the design aesthetics of the elevator car.

以下、添付図面を参照しながら本発明に係るエレベータかご内換気装置の実施形態について詳細に説明する。   Hereinafter, embodiments of an elevator car ventilation device according to the present invention will be described in detail with reference to the accompanying drawings.

［第１実施形態］
第１実施形態に係るエレベータかご内換気装置は、図１および図２に示すように、天井板１と共に天井３を構成する天井ふさぎ板１４と、天井板１と天井ふさぎ板１４との間の空間２４を封止する封止材料１５と、天井板１の通気口１７から天井３の何れかに穿設された外気吸排気口８までの間に形成される換気通路１６と、かご内１１の空気を強制的に吸排気する換気用ファン７と、を備える。図１の構成では、外気吸排気口８は天井３を構成する枠体１ａに穿設されているが、外気吸排気口８の穿設箇所は、かご外部１３と空間２４とを連絡させる位置であれば、枠体１ａでなくでも天井ふさぎ板１４に設けられていてもよい。 [First Embodiment]
As shown in FIGS. 1 and 2, the elevator car ventilation device according to the first embodiment includes a ceiling cover plate 14 that constitutes the ceiling 3 together with the ceiling plate 1, and the ceiling plate 1 and the ceiling cover plate 14. A sealing material 15 for sealing the space 24; a ventilation passage 16 formed between the vent 17 of the ceiling plate 1 and the outside air intake / exhaust port 8 drilled in any of the ceilings 3; And a ventilation fan 7 that forcibly sucks and exhausts the air. In the configuration of FIG. 1, the outside air intake / exhaust port 8 is formed in the frame 1 a constituting the ceiling 3, but the location where the outside air intake / exhaust port 8 is formed is a position where the outside of the car 13 communicates with the space 24. If so, it may be provided not on the frame body 1 a but on the ceiling cover plate 14.

天井ふさぎ板１４は、エレベータのかご内１１で照明構造体２と共に天井３を構成する天井板１をかご外部１３より覆っている。封止材料１５は、天井板１および天井ふさぎ板１４に挟まれて形成された空間２４をかご内部１１との間を封止して密閉させることにより、空間２４およびかご内１１をかご外部１３の音、振動、熱などから遮断する。通気口１ｂは、天井板１側に穿設されて、かご内１１と空間２４内との間の空気の流通を可能にする。外気吸排気口８は、天井ふさぎ板１４側に穿設されて空間２４内とかご外部１３との間の空気の流通を可能にする。換気用ファン７は、換気通路１６の通気口１ｂの近傍に設けられて空間２４および外気吸排気口８を介してかご内１１の空気およびかご外部１３の外気を強制的に吸排気する。   The ceiling cover plate 14 covers the ceiling plate 1 that constitutes the ceiling 3 together with the lighting structure 2 in the elevator car 11 from the car exterior 13. The sealing material 15 seals the space 24 formed between the ceiling plate 1 and the ceiling cover plate 14 with the inside of the car 11 so as to seal the space 24 and the inside 11 of the car. Protect from noise, vibration, heat, etc. The vent 1b is formed on the ceiling board 1 side to allow air to flow between the car 11 and the space 24. The outside air intake / exhaust port 8 is formed on the ceiling cover plate 14 side to allow air to flow between the space 24 and the outside of the car 13. The ventilation fan 7 is provided near the vent 1 b of the ventilation passage 16 and forcibly sucks and exhausts the air in the car 11 and the outside air outside the car 13 through the space 24 and the outside air intake / exhaust port 8.

第１実施形態のより詳細な構成を説明すると、図１において、天井板１は例えば外側に開口するコ字状鋼材より成る枠体１ａの下面に取り付けられ、天井ふさぎ板は枠体１ａの上面に取り付けられている。エレベータかごの天井３は、かご内１１の空間の上部外周を囲む枠体１ａの上下を天井ふさぎ板１４と天井板１とで密閉することにより形成されているが、天井板１と天井ふさぎ板１４との間には補強用の補強リブ１ｃが縦横の直交方向に交差して設けられている。   Describing a more detailed configuration of the first embodiment, in FIG. 1, the ceiling plate 1 is attached to the lower surface of a frame 1a made of, for example, a U-shaped steel material that opens outward, and the ceiling cover plate is the upper surface of the frame 1a. Is attached. The ceiling 3 of the elevator car is formed by sealing the upper and lower sides of the frame 1a surrounding the upper outer periphery of the space in the car 11 with the ceiling cover plate 14 and the ceiling plate 1, but the ceiling plate 1 and the ceiling cover plate A reinforcing rib 1c for reinforcement intersects with the vertical direction in the vertical and horizontal directions.

したがって、外周側の枠体１ａと天井板１および天井ふさぎ板１４により形成される空間２４はこの補強リブ１ｃにより小区画に仕切られている。このため、通気口１ｂが設けられる小区画と外気吸排気口８が設けられる小区画とが異なる場合、補強リブ１ｃにより換気通路１６が遮断されないように、補強リブ１ｃに換気用穴１７が形成されている。   Therefore, the space 24 formed by the frame 1a on the outer peripheral side, the ceiling plate 1 and the ceiling cover plate 14 is partitioned into small sections by the reinforcing rib 1c. For this reason, when the small compartment provided with the vent 1b and the small compartment provided with the outside air intake / exhaust 8 are different, the ventilation hole 17 is formed in the reinforcing rib 1c so that the ventilation passage 16 is not blocked by the reinforcing rib 1c. Has been.

天井板１と天井ふさぎ板１４に挟まれると共に枠体１ａに囲まれて密閉された空間２４は、その中央部付近を補強リブ１ｃにより補強されているが、補強リブ１ｃのために小区画に分割されるため、通気口１ｂと外気吸排気口８を同一の小区画に設けている場合には換気通路１６は連通する。   The space 24 sandwiched between the ceiling plate 1 and the ceiling cover plate 14 and enclosed and surrounded by the frame body 1a is reinforced by the reinforcing rib 1c in the vicinity of the central portion thereof. Since it is divided, the ventilation passage 16 communicates when the vent 1b and the outside air intake / exhaust 8 are provided in the same small section.

しかし、本発明としては通気口１ｂと外気吸排気口８との間の換気通路をできるだけ長くすることにより防音、制振、断熱効果を上げることが必要であるため、外気吸排気口８と通気口１ｂとが同一の小区画に設けられると、エレベータの昇降路内での移動により発生する騒音、振動、熱気などが外気吸排気口８からかご内１１に開口する通気口１ｂに伝達されてかご内１１の利用者に不快感を与えることになってしまう。これを防止するためにも、換気通路１６はできるだけ長く設定して、通気口１ｂと外気吸排気口８を異なる小区画に設けることになる。このため、小区画と小区画とを仕切る補強リブ１ｃに換気用穴１７を設けることが重要になる。   However, according to the present invention, it is necessary to increase the sound insulation, vibration suppression and heat insulation effects by making the ventilation path between the vent 1b and the outside air intake / exhaust 8 as long as possible. When the opening 1b is provided in the same small section, noise, vibration, hot air, etc. generated by the movement of the elevator in the hoistway are transmitted from the outside air intake / exhaust port 8 to the ventilation port 1b opened in the car 11. The user in the car 11 will be uncomfortable. In order to prevent this, the ventilation passage 16 is set as long as possible, and the vent 1b and the outside air intake / exhaust 8 are provided in different small sections. For this reason, it is important to provide the ventilation hole 17 in the reinforcing rib 1c that partitions the small section from each other.

また、第１実施形態に係るエレベータかご内換気装置において、通気口１ｂは天井板１のかご内１１の角部に少なくとも１つ設けられと共に、前記換気用ファン７は通気口１ｂに対応させて空間２４の角部に少なくとも１つ設けられていてもよい。   In the elevator car ventilator according to the first embodiment, at least one vent 1b is provided at a corner of the car 11 of the ceiling board 1, and the ventilation fan 7 is associated with the vent 1b. One or more corners of the space 24 may be provided.

さらに、第１実施形態に係るエレベータかご内換気装置において、通気口１ｂは天井板１のかご内１１の角部に複数設けられると共に、換気用ファン７は複数の通気口１ｂに対応して空間２４の角部に複数設けられていてもよい。   Furthermore, in the elevator car ventilator according to the first embodiment, a plurality of vents 1b are provided at the corners of the car 11 of the ceiling board 1, and the ventilation fan 7 is a space corresponding to the plurality of vents 1b. A plurality of 24 corners may be provided.

また、エレベータのかごの昇降に伴う振動や騒音の発生を防止するために、密閉された空間２４内の特に天井板１側には空間２４を特にかご内１１から封止するための封止材料１５が設けられている。この封止材料１５は、かごの移動による天井板１の振動がかご内１１に伝わることを防止する制振部材１８と、空間２４とかご内１１との間を伝導する冷気や熱気を遮断する断熱部材１９と、図８でも設けられていた換気用ファン７からの騒音を吸収する制音部材５等を含んでいる。   Further, in order to prevent the occurrence of vibration and noise associated with the raising and lowering of the elevator car, a sealing material for sealing the space 24 from the inside of the car 11 particularly on the ceiling plate 1 side in the sealed space 24. 15 is provided.
