Description
- The present invention relates to a machine-room less elevator apparatus in which a driving machine is installed inside a hoistway.
- In conventional machine-roomless elevator apparatuses, ventilation apparatuses are often generally unnecessary, but ventilation apparatuses are required if the temperature around a driving machine rises, etc. In answer to this, to allow for economy, etc., an elevator apparatus has been proposed in which the inside of a hoistway and the inside of a car are ventilated by a ventilation apparatus in the car while a car door is open when the car has stopped at an uppermost floor (see
Patent Document 1, for example). - Patent Document 1:
JP 2001-72347 A
As a further prior art document,WO 2005/070806 A1 refers to a drive unit for an elevator apparatus, wherein a cover body is disposed on an opening portion of the top portion of a hoistway. The driving machine for raising and lowering a car and a counterweight is supported by the cover body.
In addition,JP 2001-072353 A - However, in conventional elevator apparatuses such as that described in
patent document 1, since ventilation of a top portion of the hoistway can only be performed when the car stops at the uppermost floor, there has been a risk that the temperature in the top portion of the hoistway will increase, making the service life of machinery that is installed in the top portion of the hoistway shorter. Furthermore, it is necessary for the car to be stopped at the uppermost floor for a long time with the door open in order for ventilation of the top portion of the hoistway to be performed satisfactorily, reducing availability of the elevator apparatus. - The present invention aims to solve the above problems and an object of the present invention is to provide an elevator apparatus that enables temperature increases in a top portion of a hoistway to be suppressed efficiently.
- In order to achieve the above object, according to one aspect of the present invention, there is provided an elevator apparatus including the features of
claim 1. - According to another aspect of the present invention, there is provided an elevator apparatus including the features of
claim 7. -

-
Figure 1 is a structural diagram that shows part of an elevator apparatus according toEmbodiment 1 of the present invention. In the figure, adriving machine 2 is installed in an upper portion inside a hoistway 1 (a hoistway top portion). Thedriving machine 2 has: a drive sheave; a motor portion that rotates the drive sheave; and a brake portion that brakes rotation of the drive sheave. Thedriving machine 2 is disposed such that a rotating shaft of the drive sheave is vertical or approximately vertical. In addition, a thin hoisting machine that has a shorter axial dimension than a dimension that is perpendicular to an axial direction is used for thedriving machine 2. Thedriving machine 2 is supported by a supporting beam (not shown) that is fixed to the hoistway top portion. - A
car 3 and a counterweight (not shown) are suspended inside thehoistway 1 by a main rope (not shown) that is wound around the drive sheave, and are raised and lowered inside thehoistway 1 by a driving force from thedriving machine 2. - A
ventilating duct 4 for ventilating the hoistway top portion is installed in an upper portion inside thehoistway 1. Theventilating duct 4 has: an upper portion air supply andexhaust opening 4a that is positioned higher than alanding entrance 5 of an uppermost floor inside thehoistway 1; and a lower portion air supply and exhaust opening 4b that is positioned lower than the upper portion air supply andexhaust opening 4a inside thehoistway 1. - The upper portion air supply and
exhaust opening 4a is positioned in the hoistway top portion and faces a side surface of thedriving machine 2. The lower portion air supply andexhaust opening 4b is positioned above a floor surface level of the uppermost floor inside thehoistway 1 and opens directly downward. Specifically, theventilating duct 4 is bent approximately at a right angle in a vicinity of the upper portion air supply andexhaust opening 4a such that an end portion near the upper portion air supply andexhaust opening 4a of theventilating duct 4 is horizontal and an end portion near the lower portion air supply andexhaust opening 4b is vertical. An upper end portion of theventilating duct 4 is fixed to the supporting beam that supports thedriving machine 2. Specifically, a driving machine mount portion to which thedriving machine 2 is mounted and a duct mount portion to which theventilating duct 4 is mounted are disposed on the supporting beam. - In an elevator apparatus of this kind, when the
car 3 is raised inside thehoistway 1, air in an upper portion inside thehoistway 1 is pushed by thecar 3 and flows down through theventilating duct 4, as indicated by arrows inFigure 1 . When thecar 3 is lowered, on the other hand, warm air in the top portion of the hoistway is lowered with thecar 3 and comparatively cold air is raised through theventilating duct 4, as indicated by arrows inFigure 2 . Temperature increases in the vicinity of the hoistway top portion are thereby suppressed efficiently, ensuring a temperature safety margin for machinery that is disposed in the hoistway top portion such as thedriving machine 2, etc., enabling service life of the machinery to be extended. -
Figure 3 is a graph that shows relationships between distance from a hoistway ceiling inFigure 1 and temperature, the broken line representing a case in which ventilation that uses theventilating duct 4 is not performed and the solid line representing a case in which ventilation that uses theventilating duct 4 is performed. If ventilation is not performed, the temperature in the top portion of the hoistway is highest at the ceiling portion and decreases rapidly in the vicinity of thelanding entrance 5 of the uppermost floor, as indicated by the broken line inFigure 3 . In contrast, if ventilation is performed, the temperature in the top portion of the hoistway can be reduced, as indicated by the solid line inFigure 3 . Furthermore, since ventilation between a landing and a vicinity of thelanding entrance 5 is easily performed by opening and closing the door, temperature increases are only slight even if warm air from the top portion of the hoistway is conveyed there by theventilating duct 4. - Here, since aperture area of the upper portion air supply and
exhaust opening 4a of theventilating duct 4 is sufficiently smaller than a vertical footprint area of thecar 3, airflow velocity inside theventilating duct 4 will be sufficiently faster than a traveling speed of thecar 3 if flow channels of air that might flow outside theventilating duct 4 due to ascent and descent of thecar 3 are blocked as much as possible. If, for example, the vertical footprint area of thecar 3 is ten times the aperture area of the upper portion air supply andexhaust opening 4a then, ignoring loss, the airflow velocity inside theventilating duct 4 will be ten times the traveling speed of thecar 3. - Thus, by increasing the airflow velocity inside the
ventilating duct 4 and disposing the upper portion air supply andexhaust opening 4a so as to face machinery that is disposed in the hoistway top portion such as thedriving machine 2, etc., a cooling airflow can be blown onto the machinery in the top portion of the hoistway as thecar 3 descends, enabling the machinery to be cooled efficiently. Fans that are disposed on the machinery in the top portion of the hoistway can thereby be reduced in size or eliminated, enabling the machinery to be reduced in size. - Next,
Figure 4 is a structural diagram that shows part of an elevator apparatus according toEmbodiment 2 of the present invention. In the figure, a control apparatus 6 that controls adriving machine 2 is installed inside ahoistway 1. The control apparatus 6 is fixed to a hoistway wall so as to be approximately equal in height to an uppermost floor. Acooling fan 7 is disposed on the control apparatus 6. - A lower portion air supply and
exhaust opening 4b is disposed so as to face an upper surface of the control apparatus 6. A plurality of electrical wires (not shown) that connect the control apparatus 6 and thedriving machine 2 are inserted through and accommodated in aventilating duct 4. In other words, theventilating duct 4 also serves as a wiring duct. The rest of the configuration is similar to that ofEmbodiment 1. - In an elevator apparatus of this kind, because the control apparatus 6 is disposed so as to face the lower portion air supply and
exhaust opening 4b, ventilation of the top portion of the hoistway can be performed through theventilating duct 4 by driving thecooling fan 7 of the control apparatus 6 even when thecar 3 has stopped or is being raised and lowered at lower floors, etc., enabling temperature increases in the top portion of the hoistway to be suppressed efficiently. - Because the
ventilating duct 4 also serves as a wiring duct, costs can be reduced and effective utilization of space can be achieved. - Next,
Figure 5 is a structural diagram that shows part of an elevator apparatus according toEmbodiment 3 of the present invention. In the figure, a drivingmachine 12 is installed in an upper portion inside a hoistway 11 (a hoistway top portion). The drivingmachine 12 has : a drive sheave; a motor portion that rotates the drive sheave; and a brake portion that brakes rotation of the drive sheave. The drivingmachine 12 is disposed such that a rotating shaft of the drive sheave is horizontal. In addition, the drivingmachine 12 is supported by a supporting beam (not shown) that is fixed to the hoistway top portion. - A
deflection sheave 13 is disposed in a vicinity of the drivingmachine 12. Amain rope 14 is wound around the drive sheave and thedeflection sheave 13. Acar 15 and acounterweight 16 are suspended inside thehoistway 11 by themain rope 14, and are raised and lowered inside thehoistway 11 by a driving force from the drivingmachine 12. - A
control apparatus 17 that controls the drivingmachine 12 is installed in the hoistway top portion. Thecontrol apparatus 17 is fixed to a hoistway wall in the hoistway top portion. Aflat partitioning plate 18 is installed between a hoisting zone of thecar 15 and a hoisting zone of thecounterweight 16 in an upper portion inside the hoistway11. Thepartitioning plate 18 blocks circulation of air between those two zones. Thepartitioning plate 18 has: anupper end portion 18a that is positioned higher than alanding entrance 5 of an uppermost floor inside thehoistway 11; and alower end portion 18b that is positioned lower than theupper end portion 18a of thepartitioning plate 18 inside thehoistway 11. - The
upper end portion 18a is disposed between the drivingmachine 12 and thedeflection sheave 13. Thelower end portion 18b is positioned higher than a floor surface level of the uppermost floor. Thepartitioning plate 18 is fixed to at least one hoistway wall, or to the supporting beam, or to a combination thereof. - In an elevator apparatus of this kind, when the
car 15 is raised inside thehoistway 11 and thecounterweight 16 is lowered, an air current such as that indicated by arrows inFigure 5 arises inside thehoistway 11, warm air in the hoistway top portion flows down through a passage near thecounterweight 16, and cool air below flows upward with thecar 15. On the other hand, when thecar 15 is lowered and thecounterweight 16 is raised, warm air in the hoistway top portion flows downward with thecar 15 and cool air below flows upward through the passage near thecounterweight 16. - Temperature increases in the vicinity of the hoistway top portion are thereby suppressed efficiently, ensuring a temperature safety margin for machinery that is disposed in the hoistway top portion such as the driving
machine 2, etc., enabling service life of the machinery to be extended. The air current can also be regulated by thepartitioning plate 18, enabling hoisting resistance of thecar 15 to be reduced. - Next,
Figure 6 is a structural diagram that shows part of an elevator apparatus according toEmbodiment 4 of the present invention. In this example, alower end portion 18b of apartitioning plate 18 is positioned lower than that ofEmbodiment 3. In other words, a vertical dimension of thepartitioning plate 18 is longer than that ofEmbodiment 3. Specifically, thelower end portion 18b is positioned in a vicinity of a floor that is two floors lower than an uppermost floor. The rest of the configuration is similar to that ofEmbodiment 3. - In an elevator apparatus of this kind, a range over which air inside the
hoistway 11 is agitated by raising and lowering thecar 15 and thecounterweight 16 is increased. Consequently, the temperature of the warm air flowing downward from the hoistway top portion is gradually reduced by a hoistway wall, which functions as a radiatingsurface 19. Temperature increases in the vicinity of the hoistway top portion are thereby suppressed more reliably. - Next,
Figure 7 is a structural diagram that shows part of an elevator apparatus according toEmbodiment 5 of the present invention. In the figure, a ventilatingduct 4 similar to that ofEmbodiment 1 is installed in an upper portion inside ahoistway 1. A coolingfan 21 is disposed inside the ventilatingduct 4. Atemperature detector 22 for detecting hoistway top portion temperature is disposed on a ceiling portion of thehoistway 1. Detection signals from thetemperature detector 22 are input into thecontrol apparatus 17. - The
control apparatus 17 detects the hoistway top portion temperature based on the signals from thetemperature detector 22. If the hoistway top portion temperature reaches a preset temperature, thecontrol apparatus 17 moves thecar 15 to an upper floor to perform a ventilation operation by raising and lowering thecar 15 and thecounterweight 16. If thecar 15 cannot be moved to an upper floor, or if thecar 15 must be stopped, thecontrol apparatus 17 drives the coolingfan 21 to ventilate the hoistway top portion forcibly. The rest of the configuration is similar to that ofEmbodiment 3. - In an elevator apparatus of this kind, temperature increases in a vicinity of the hoistway top portion can be suppressed efficiently while giving priority to service to passengers.
- Moreover, in the above examples, the driving
machine - The driving machine may also be a long, slender hoisting machine in which an axial dimension is longer than a dimension that is perpendicular to an axial direction, enabling similar effects to be achieved.
- In addition, in the above examples, a
single ventilating duct 4 was used, but a plurality of ventilating ducts may also be used. - In the above examples, a single upper portion air supply and
exhaust opening 4a was disposed on asingle ventilating duct 4, but a ventilating duct that has a plurality of upper portion air supply and exhaust openings may also be used. Similarly, a ventilating duct that has a plurality of lower portion air supply and exhaust openings may also be used. - If the upper portion air supply and exhaust opening of the ventilating duct is made to face the driving machine, extension of service life of a comparatively weak encoder (a rotation detector that generates signals that correspond to rotation of the motor portion) that is disposed on the driving machine can be achieved by making the upper portion air supply and exhaust opening face the encoder.
