The flat plate portion 9 and the curved surface portion 10 that is inclined from the front end side toward the outer peripheral edge portion of the car room 5 are formed in a tapered shape.
[0017]
Reference numeral 11 denotes an inflow passage that opens near the tip of the flat plate portion 9 of the air conditioning cover 8. One inflow is pivotally attached to the edge of the inflow passage 11 and retreats inward when opened to form an inclined surface that approaches the cab 5. The closing plate 12, a support arm 13 provided at the edge of the inflow passage 11, and an inflow side drive mechanism 14 including an electric cylinder that opens and closes the inflow closing plate 12 are provided on the support arm 13, which will be described in detail later. Yes.
[0018]
Reference numeral 15 denotes an outflow passage, which is provided at a position corresponding to both side surfaces of the cab 5 of the wind regulation cover 8 and opens to the base portion of the curved portion 10 of the wind regulation cover 8, that is, a position away from the flat plate portion 9. It is arranged close to the chamber 5 and is connected to the outer surface from the inside, and is formed with an inclined surface 16 that guides the air flow in the horizontal direction, and one side is pivotally attached to the edge of the outflow passage 15 to close the outflow passage 15 when necessary. The outflow closing plate 17, a support arm 18 provided at the edge of the outflow passage 15, and an outflow side drive mechanism 19 including an electric cylinder that is provided on the support arm 18 and opens and closes the outflow closing plate 17 are described later. ing.
[0019]
Reference numeral 20 denotes a control device which is connected to the inflow side drive mechanism 14 and the outflow side drive mechanism 19 and opens the inflow blocking plate 12 and the outflow blocking plate 17 provided in the head wind regulation cover 8 in the ascending / descending direction when the car 3 is lifted / lowered. In addition, it commands the closing of the inflow blocking plate 12 and the outflow blocking plate 17 provided in the wind-control cover 8 on the rear side in the ascending / descending direction.
[0020]
For example, when the car 3 moves up and down in the direction of arrow A shown in FIGS. 1 and 2, that is, ascends, air flows in the direction of arrow B and arrow C. Then, the air flow B outside the car 3 hits the tip of the airflow cover 8 and leaves the outer surface of the car 3, then hits the inner surface of the hoistway 1 and approaches the outer surface of the car 3 again. For this reason, the separation region D shown in FIG. 2 occurs in the air flow B outside the car 3. Further, when the car 3 is lowered, the air flows in the opposite arrow B direction and the opposite arrow C direction, and the separation region D shown in FIG.
[0021]
In the elevator car apparatus constructed as described above, the air flow when the car 3 moves up and down at high speed is formed by a tapered shape formed by the flat plate portion 9 and the curved surface portion 10 whose depth and depth gradually decrease toward the tip. Rectified by the cover 8. That is, since the curved portion 10 suppresses the generation of air eddy currents, the noise in the cab 5 is reduced. In addition, because of the gap between the car door 7 and the entrance 6, the inflow of air to the entrance / exit 6 having poor sound insulation is prevented by the flat plate portion 9, and the amount of inflow of air to the entrance / exit 6 is reduced.
[0022]
In addition, the inflow path 11 and the inflow blocking plate 12 and the outflow blocking plate 17 of the outflow path 15 provided in the wind regulation cover 8 on the leading side in the up-and-down direction of the car 3 are opened. Thereby, the low pressure which the air which flowed in between the hoistway 1 inner surface and the flat plate part 9 of the wind regulation cover 8 produces in the peeling area | region D of the air flow B outside the cage | basket 3 from the inflow path 11 which is the high voltage | pressure side of the wind regulation cover 8 is produced. It flows out to the outflow passage 15 provided on the side and closer to the car room 5 than the inflow passage 11.
In addition, even if it is the structure which has arrange | positioned the outflow path 15 in the back surface equivalent position facing the entrance / exit 6 of the cage | basket | chamber 5, the effect | action in embodiment of FIGS. 1-10 can be acquired.
[0023]
This can further reduce the inflow of air from the flat plate portion 9 of the air conditioning cover 8 to the entrance / exit 6 having poor sound insulation due to the gap between the car door 7. For this reason, in the narrow space between the hoistway 1 inner surface and the car 3, the air flow contracts and the flow velocity increases, so that the noise increases, and the noise enters the car room 5 from the gap between the car door 7 and the entrance 6. The transmitted phenomenon can be prevented, and the riding comfort of the car 3 can be improved.
[0024]
In addition, in a typical car 3 of about 20 passengers, the effective opening of the inflow channel 11 has an opening of about 10 cm and a height of about 80 cm, and the outflow channel 15 is provided on both sides of the car 3 as shown in FIG. The effective opening of one outflow passage 15 is about 20 cm wide and about 20 cm high. As a result, a flow rate corresponding to approximately 2/1 of the air flow flowing into the entrance / exit 6 of the car 3 flows out from the outflow passage 15 to the outer surface of the car 3.
[0025]
For this reason, since the air flow rate on the car 3 doorway 6 side is halved, aerodynamic noise generated on the car 3 doorway 6 side can be reduced. Since the aerodynamic noise is proportional to the sixth power of the air flow velocity, the noise reduction effect of about 18 dBA can be obtained with respect to the noise generated on the side of the car 3 entrance 6 with the effective opening area such as the inflow path 11 described above. Can do. And all the noises in the cab 5 can be reduced by about 2 to 3 dBA.
[0026]
In general, the space area on the inner surface of the hoistway 1 and the car 3 doorway 6 side is very narrow compared to the side surface side and the back surface side of the car 3. Therefore, even if air flows out to the side surface of the car 3 or the back surface side of the car 3, the increase in the air flow on the outflow side can be regarded as an error range. For this reason, there is no fear that the aerodynamic noise increases due to the increase of the air flow on the outflow side.
[0027]
In addition, the outflow path 15 is provided with an inclined surface 16 that is formed so as to be connected to the outer surface from the inside of the air conditioning cover 8 and that guides the air flow in the horizontal direction. As a result, air flows out from the outflow passage 15 in the horizontal direction, so that it is possible to reduce the occurrence of noise due to vortices or the like due to the outflowing air, regardless of the up-and-down direction of the car 3. Therefore, the noise in the car room 5 can be reduced and the riding comfort of the car 3 can be improved.
[0028]
In addition, the control device 20 opens the inflow path 11 and the inflow blocking plate 12 and the outflow blocking plate 17 of the outflow path 15 provided in the wind-control cover 8 on the leading side in the up-and-down direction of the car 3, so The inflow blocking plate 12 and the outflow blocking plate 17 provided on the cover 8 are closed. This prevents air from flowing through the inflow path 11 and the outflow path 15 of the tail wind-control cover 8 in the up-and-down direction, prevents noise from occurring in the tail-side wind control cover 8, and improves the riding comfort of the car 3. Can do.
[0029]
Further, the area of the total effective opening of the outflow passage 15 is set wider than the area of the effective opening of the inflow passage 11. As a result, the air flowing into the wind regulation cover 8 from the inflow path 11 efficiently flows out of the outflow path 15. For this reason, the noise produced by the turbulent flow etc. of the flowing-out air reduces and the riding comfort of the car 3 can be improved.
[0030]
Embodiment 2
11 and 12 are views showing an example of another embodiment of the present invention. FIG. 11 is a longitudinal side view showing an elevator car apparatus. FIG. 12 is a left side view of the elevator car apparatus shown in FIG. is there. In the figure, the same reference numerals as those in FIGS. 1 to 10 denote the corresponding parts, 21 is a duct, and one end is formed at the edge of the inflow passage 11 and the inclined surface 22 which is retracted inward and approaches the cab 5 is shown. To the opening of the inflow passage 11, extended into the air conditioning cover 8 and branched, and the other ends are connected to the outflow passages 15 on both side surfaces of the air conditioning cover 8.
[0031]
Reference numeral 23 denotes a blower, which is provided in the duct 21 so as to correspond to each of the outflow passages 15 on both sides, and blows air toward the outflow passage 15. Reference numeral 24 denotes a control device connected to each of the blowers 23. The control device 24 is provided to the urge of the blower 23 provided on the head wind-conditioning cover 8 in the up-and-down direction when the car 3 is raised and lowered and to the wind-control cover 8 on the rear side in the up-and-down direction. The fan 23 is instructed to be turned off.
[0032]
For example, when the car 3 moves up and down in the direction of arrow A shown in FIGS. 11 and 12, that is, ascends, air flows in the directions of arrow B and C. Although not shown in the figure, the air flow B outside the car 3 hits the tip of the airflow cover 8 and leaves the outer surface of the car 3, then hits the inner surface of the hoistway 1 and again approaches the outer surface of the car 3. For this reason, the separation region D shown in FIG. 2 occurs in the air flow B outside the car 3. Further, when the car 3 is lowered, the air flows in the opposite arrow B direction and the opposite arrow C direction, and the separation region D shown in FIG.
[0033]
Also in the elevator car apparatus configured as described above, the inflow path 11 and the outflow path 15 are provided in the air conditioning cover 8, and the air that flows between the inner surface of the hoistway 1 and the flat plate portion 9 of the air conditioning cover 8 flows in. It flows out from the path 11 to the outflow path 15. Therefore, although the detailed description is omitted, the same operation as the embodiment of FIGS. 1 to 10 can be obtained also in the embodiment of FIGS.
[0034]
11 and 12, the air that has flowed into the inflow path 11 flows out to the outflow path 15 through the duct 21. For this reason, it is possible to prevent noise caused by an air flow generated due to a gap generated in the structure such as between the cab 5 and the wind regulation cover 8 and a notch in the structure. Therefore, it is possible to easily manufacture a structure body such as the wind regulation cover 8 and to reduce the cost.
[0035]
Further, a blower 23 is provided in the duct 21 and is energized by the control device 24 in accordance with the raising / lowering direction of the car 3 and is blown toward the outflow path 15. For this reason, the air that has flowed in between the inner surface of the hoistway 1 and the flat plate portion 9 of the wind regulation cover 8 is forcibly blown from the inflow path 11 to the outflow path 15 and discharged. Therefore, it is possible to further reduce the inflow of air from the flat plate portion 9 of the air conditioning cover 8 to the entrance / exit 6 having poor sound insulation due to the gap between the car door 7 and the entrance / exit 6. For this reason, the noise transmitted to the inside of the car room 5 can be prevented, and the riding comfort of the car 3 can be further improved.
[0036]
Note that a straight sirocco fan with a diameter of about 20 cm to 22 cm, which is generally marketed, is installed in the duct 21 having a frontage of 20 cm and a height of about 20 cm as a blower 23 for an elevator having an ascending / descending speed of 600 m / min or more. As a result, the air flowing between the inner surface of the hoistway 1 and the flat plate portion 9 of the airflow control cover 8 can be forcibly blown and discharged from the inflow path 11 to the outflow path 15 to obtain a required noise prevention effect. be able to.
[0037]
Also, the blower 23 is provided on the upper and lower surfaces of the car room 5 having high sound insulation, and only one of the blowers 23 on the upper and lower surfaces of the car room 5 is operated according to the raising and lowering direction of the car 3. For this reason, the noise in the car room 5 increases due to the operation of the blower 23, and there is no possibility that the riding comfort of the car 3 is lowered as a side effect.
[0038]
【The invention's effect】
As described above, the present invention is provided with a car room disposed in a hoistway and provided with an entrance on the front side, and an upper surface and a lower surface of the car room are respectively covered and disposed at positions corresponding to the front side of the car room. A flat plate part is formed which is arranged facing the inner surface of the hoistway and has a small gap, and is formed in a tapered shape with the frontage and depth gradually decreasing toward the tip, and is opened near the tip of the flat plate part. An inflow channel formed by an inclined surface that only retreats inward to the cab and an inclined surface that opens to a position away from the flat plate portion and is located closer to the cab than the inflow channel and is connected to the outer surface from the inside. And a wind regulation cover having an outflow path.
[0039]
As a result, the air flow when the car moves up and down is rectified by the flat plate portion and the wind-tuning cover formed in a tapered shape, and the generation of vortex is suppressed and the noise in the car room is reduced. In addition, the inflow of air to the entrance / exit side of the car is suppressed by the flat plate portion, and the air that flows between the inner surface of the hoistway and the flat plate portion of the conditioned cover covers the inside of the conditioned cover from the inflow channel on the high pressure side of the conditioned cover. It flows out to the outflow passage through. Therefore, the inflow of air to the entrance / exit side of the car can be further reduced. As a result, the air flow is reduced in the narrow space between the hoistway and the interior of the car, increasing the flow velocity, increasing the noise and preventing the noise from being transmitted from the car door gap to the car room. There is an effect of improving.
[0040]
In addition, as described above, the present invention is provided with a duct having one end connected to the opening of the inflow passage and extended into the wind regulation cover, and the other end connected to the opening of the outflow passage.
[0041]
Thereby, the air that has flowed into the inflow path flows out to the outflow path through the duct. For this reason, it is possible to prevent noise caused by an air flow generated due to a gap generated in the structure body such as between the cab and the wind regulation cover and a notch portion in the structure body. Therefore, it is possible to easily manufacture a structure such as a windbreak cover and to reduce the cost.
[0042]
Further, as described above, the present invention is provided with a blower that is arranged in the duct and blows air in the direction of the outflow path.
[0043]
As a result, the air that has flowed in between the hoistway inner surface and the flat plate portion of the wind regulation cover is forcibly blown from the inflow path to the outflow path and discharged. Therefore, because of the gap between the flat plate portion of the air conditioning cover and the door of the car and the entrance / exit, the inflow of air to the entrance / exit side having poor sound insulation can be further reduced, and noise transmitted to the car room can be prevented. This has the effect of further improving the ride comfort of the car.
[0044]
In addition, as described above, the present invention is provided with an inclined surface that is provided in the outflow passage and is connected to the outer surface from the inside of the air conditioning cover and that guides the air flow in the horizontal direction.
[0045]
As a result, air flows out from the outflow path in the horizontal direction, so that it is possible to reduce the occurrence of noise due to vortices and the like caused by the outflowing air, regardless of the direction in which the car is raised or lowered. Accordingly, there is an effect of reducing the noise in the car room and improving the riding comfort of the car.
[0046]
In addition, as described above, the present invention provides a closing plate provided in at least one of the inflow path and the outflow path, a drive mechanism for driving the closing plate, and a wind regulation cover on the leading side in the ascending / descending direction when the car is lifted / lowered. And a control device that commands opening of the closing plate provided and closing of the closing plate provided on the tailing cover on the rear side in the ascending / descending direction.
[0047]
As a result, the control device closes the closing plate provided on the airflow control cover on the rear side of the car in the up-and-down direction of the car, and air does not flow through the inflow path and outflow path of the air-conditioning cover on the rear side in the up-and-down direction. This can prevent noise from being generated on the side windbreak cover and improve the riding comfort of the car.
[0048]
In addition, as described above, the present invention is such that the area of the effective opening of the outflow path is set wider than the area of the effective opening of the inflow path.
[0049]
As a result, the air flowing from the inflow path into the wind regulation cover efficiently flows out from the outflow path. For this reason, the noise produced by the turbulent flow of the flowing-out air etc. reduces, and there exists an effect which improves the riding comfort of a cage | basket | car.
[0050]
In addition, as described above, the present invention is such that the outflow path is arranged in the separation region where the air flow outside the car hits the tip of the wind regulation cover and moves away from the outer surface of the car by raising and lowering the car.
[0051]
As a result, the outflow path of the wind regulation cover is provided in the separation region where the air flow outside the car is separated from the outer surface of the car and becomes the low pressure side by raising and lowering the car. For this reason, the air which flowed in between the hoistway inner surface and the flat plate part of the wind regulation cover efficiently flows out from the inflow path on the high pressure side to the outflow path on the low pressure side. Therefore, the inflow of air from the flat plate portion of the air conditioning cover to the entrance / exit side of the car can be further reduced. For this reason, noise is increased by reducing the air flow in the narrow space between the hoistway inner surface and the cage and increasing the flow velocity, preventing the noise from being transmitted from the gap between the car doors to the car room. It has the effect of improving the ride comfort.
