In FIG. 1, 1 is an elevator car, and the right side of FIG. 1 is a door side on which a user gets on and off. Reference numeral 2 denotes an elevator hoistway, and FIG. 1 shows a configuration having no machine room at the top, but it can also be implemented by an elevator having a machine room. Reference numeral 3 denotes an outdoor unit of an air conditioner fixedly installed on the upper portion of the cage 1 and is configured to release generated heat to the outside by forced exhaust or the like. An exhaust duct 4 is installed inside the hoistway 2 along the operation range of the cage 1, and the axis of the exhaust duct is along the operation of the cage 1. In the present embodiment, since the basket 1 operates in the vertical direction, the exhaust duct 4 is also arranged in the vertical direction. An exhaust pipe 5 has one end fixed to the air conditioner 3 and the other end inserted into the exhaust duct 4. Reference numeral 6 denotes an outlet provided in the upper part of the hoistway 2, which is connected to the upper end of the exhaust duct 4.
[0012]
FIG. 3 shows an example of a configuration in which the exhaust pipe 5 is inserted into the exhaust duct 4. The exhaust duct 4 is provided with an opening along the direction of operation of the basket. Reference numeral 7 denotes a brush that is provided at the opening and is configured using a flexible material. On the insertion surface of the exhaust duct 4, a brush 7 whose tip is directed from the left to the center and a brush 7 whose tip is directed from the right to the center is opposed to each other. In a portion where the exhaust pipe 5 is not inserted into the exhaust duct 4 and no external force is applied to the brush 7, both end portions are configured to coincide or slightly overlap, so that a large gap is generated on the insertion surface. Absent. On the other hand, at the portion where the exhaust pipe 5 is inserted into the exhaust duct 4, the brush 7 is in close contact with the exhaust pipe 5 and is curved, so that air leakage from the exhaust duct 4 to the hoistway 2 is suppressed.
[0013]
As the car 1 moves up and down, the exhaust pipe 5 also moves up and down, and the part where the exhaust pipe 5 is inserted into the exhaust duct 4 also moves. In the portion where the exhaust pipe 5 has been inserted and the brush 7 has been deformed so far, the shape of the brush is restored so that no gap is generated on the insertion surface, and in the portion where the exhaust pipe 5 is newly inserted, the brush 7 is exhausted. Curved in close contact with the pipe 5. Since the brush 7 of the exhaust duct 4 is provided along the direction of operation of the car 1, the brush is deformed so that the exhaust pipe 5 is moved up and down from the exhaust duct 4 while the exhaust pipe 5 is inserted into the exhaust duct 4. The cage 1 can be moved up and down while suppressing air leakage to the path 2. In FIG. 3, the brush 7 is provided in the exhaust duct 4, but it is also possible to use other members having elasticity such as rubber and vinyl instead of the brush 7.
[0014]
In the elevator air conditioner configured as described above, the exhaust heat of the air conditioner 3 is released into the exhaust duct 4 through the exhaust pipe 5, and this warm air rises in the exhaust duct 4 due to the difference in specific gravity of air. By the chimney effect, it is discharged from the discharge port 6 at the upper end to the outside of the hoistway 2. At that time, as shown in the description of FIG. 3 above, since air leakage from the exhaust duct 4 is suppressed, most of the exhaust heat of the air conditioner 3 can be discharged from the discharge port 6.
[0015]
As described above, since the elevator air conditioner according to this embodiment is configured to exhaust the exhaust heat that has been released to the hoistway from the exhaust duct, the temperature increase of the hoistway is suppressed. In addition, the operating efficiency of air conditioners installed in the basket will be improved. Also, the initial construction alone requires little maintenance costs and can be kept low.
[0016]
In addition, in a place where a plurality of elevator cars are operating in parallel, a plurality of configurations in which brushes face each other as described above are provided in one exhaust duct without providing one exhaust duct in each car. It is also possible to insert an exhaust pipe in each. FIG. 4 shows a configuration in which two exhaust pipes exhaust to a common exhaust duct. In FIG. 4, 1 and 1a are elevator cages, 3 and 3a are air conditioners of the car 1 and the car 1a, 4a is an exhaust duct, and 5 and 5a are fixed to the air conditioner 3 and the air conditioner 3a, respectively. The exhaust pipes 7 and 7a are brushes. The exhaust duct 4a is installed along the operation range of the car 1 and the car 1a, the opening is provided along each operation range of the car 1 and the car 1a, and the exhaust pipe 5 and the exhaust pipe 5a are inserted respectively. Is done. Reference numerals 7 and 7a are brushes provided in the opening, but the configuration is the same as that in FIG.
[0017]
By comprising in this way, since the exhaust_gas | exhaustion of the exhaust pipe 5 and the exhaust pipe 5a can be processed by one exhaust duct 4a without a big air leak, the installation cost of an exhaust duct can be restrained low.
[0018]
