Abstract
The invention provides an elevator and a car capable of reducing noise generated during lifting movement. The elevator comprises a car (120). The car (120) has a car chamber (121), a door unit, and a cowling (10A) provided in the car chamber (121). The cowling (10A) has a flat plate-like front surface section (11) parallel to the vertical direction. The front surface part (11) is opposite to the elevator hall side wall surface (110 a). The front surface part (11) is provided with an air vent (15) into which air (W1) flowing between the front surface part (11) and the elevator hall side wall surface (110a) flows.
Description
Technical Field
The present invention relates to an elevator and a car.
Background
In recent years, as building structures have been raised to higher levels, the distance over which the car is raised and lowered has become longer, and the speed at which the car is raised and lowered has been required to be higher. If the elevating speed of the car is increased, a turbulent flow is generated in the air flow (airflow) around the car. Further, turbulence generated around the car causes noise when the car moves up and down.
In particular, in a building structure, a space between an elevator hall side wall surface provided with a building side door and a car is narrow, and a door unit of the building side door and the car is disposed between the elevator hall side wall surface and the car so as to extend along an elevator shaft. When air flows between the hall side wall surface and the car, the air enters a gap of the door unit, or the air collides with the door unit, thereby generating noise.
As a technique for reducing noise generated when the car is moved up and down, for example, a technique described in patent document 1 is known. Patent document 1 describes a technique including two parts: a car provided with a door and ascending and descending in the elevator shaft; and a rectification structure body arranged above and below the lift car. The rectifying structure has a valley portion extending from a top portion of the rectifying structure toward a back side of the car. In the technique described in patent document 1, the airflow flows along the trough portion toward the back side of the car, and therefore, the airflow is prevented from flowing toward the front side of the car.

Detailed Description
An elevator and a car according to an embodiment will be described below with reference to fig. 1 to 5. In the drawings, the same reference numerals are given to the common members.
1. Embodiment 1
1-1. Structure of elevator
First, the structure of an elevator according to embodiment 1 (hereinafter referred to as "the present example") will be described with reference to fig. 1 and 2.
Fig. 1 is a schematic configuration diagram showing a configuration example of an elevator of this example. Fig. 2 is a horizontal cross-sectional view showing the elevator shaft of the elevator of this example.
As shown in fig. 1, the elevator 1 of this example is provided in an elevator shaft 110 formed in a building structure. The elevator 1 performs a lifting operation in the elevator shaft 110, and includes a car 120 on which people or goods are loaded, a rope 130, a counterweight 140, and a hoisting machine 100.
The hoisting machine 100 is disposed in a machine room 160 provided at the top of the elevator shaft 110, and winds the rope 130 to raise and lower the car 120. In addition, a return sheave 150 for mounting the rope 130 is provided near the hoisting machine 100 in the machine room 160.
The car 120 is mounted to one axial end of the rope 130, and the counterweight 140 is mounted to the other axial end of the rope 130. Thus, the car 120 is coupled to the counterweight 140 via the ropes 130. When the hoisting machine 100 is driven, the car 120 and the counterweight 140 are lifted and lowered. Hereinafter, the direction in which the car 120 and the counterweight 140 move up and down is referred to as the vertical direction.
In the elevator hall 200, which is an upper and lower passenger floor where the car 120 stops in the building structure, an entrance for people or articles to get in and out of the car 120 is provided. A building side door 201 is attached to the doorway so as to be openable and closable. As shown in fig. 2, the doorway and building side door 201 is provided on a hall side wall surface 110a facing a door unit 122 of a car 120 described later in the elevator hoistway 110.
1-2 structural example of car
Next, the structure of the car 120 will be described with reference to fig. 2 to 4.
Fig. 3 is a perspective view showing the car 120. Fig. 4 is a side view showing an upper portion of the car 120.
As shown in fig. 1 and 3, the car 120 includes a compartment 121, a door unit 122, a 1 st fairing 10A, and a 2 nd fairing 10B. As shown in fig. 1 and 2, the compartment 121 is formed in a substantially hollow rectangular parallelepiped shape. The compartment 121 has four side wall portions 121a, 121b, 121c, 121 d. The 1 st side wall part 121a is opposed to the 2 nd side wall part 121b, and the 3 rd side wall part 121c is opposed to the 4 th side wall part 121 d.
The 1 st side wall 121a of the compartment 121 is provided with an entrance 124. Then, the person or the cargo enters and exits the interior space of the compartment 121 through the doorway 124. The door unit 122 is provided openably and closably in the entrance 124. When the car 120 stops at any floor, the door unit 122 faces a building side door 201 provided in the building structure.
As shown in fig. 2, the interval T1 between the 1 st side wall part 121a and the hall-side wall surface 110a in the elevator shaft 110 is set narrower than the interval T2 between the 2 nd side wall part 121b and the wall surface 110b of the elevator shaft 110 that opposes the hall-side wall surface 110 a. Further, the interval T1 between the 1 st side wall part 121a and the hall side wall surface 110a is set narrower than the interval T3 between the 3 rd side wall part 121c and the wall surface 110c of the elevator shaft 110 that faces the 3 rd side wall part 121 c.
Therefore, when air flows between the 1 st side wall portion 121a and the hall side wall surface 110a during the up-down movement, the air enters a gap of the door unit 122, or the air collides with the door unit 122 and the building side door 201, and noise is likely to be generated. In order to reduce such noise, the car 120 is provided with a 1 st fairing 10A and a 2 nd fairing 10B.
As shown in fig. 1 and 3, the 1 st fairing 10A is disposed at an upper portion of the chamber 121 in the vertical direction, and the 2 nd fairing 10B is disposed at a lower portion of the chamber 121 in the vertical direction. The 1 st fairing 10A protrudes upward in the vertical direction from the upper portion of the compartment 121, and the 2 nd fairing 10B protrudes downward in the vertical direction from the lower portion of the compartment 121. The 1 st fairing 10A covers an upper portion of the compartment 121, and the 2 nd fairing 10B covers a lower portion of the compartment 121. Since the 1 st fairing 10A and the 2 nd fairing 10B have the same configuration, the 1 st fairing 10A will be described here.
As shown in fig. 3 and 4, the 1 st fairing 10A is formed in a hollow dome shape having a flat surface on one surface. The 1 st fairing 10A has a front surface portion 11, a rear surface portion 12, and two side surface portions 13.
The front portion 11 is disposed on the door unit 122 side of the compartment 121, i.e., on the 1 st side wall portion 121a side. The front surface portion 11 is formed in a flat plate shape, and has rounded upper end portions in the vertical direction. The front surface portion 11 faces the hall side wall surface 110a and is disposed substantially parallel to the 1 st side wall portion 121 a. Then, the front surface portion 11 is disposed in parallel with the vertical direction.
The back surface portion 12 facing the front surface portion 11 is formed in a curved surface shape and is curved in a streamline shape in the vertical direction. Then, the back surface portion 12 is connected to the 2 nd side wall portion 121 b. The two side portions 13 and 13 are disposed between the front portion 11 and the rear portion 12. As with the back surface portion 12, the two side surface portions 13 and 13 are formed into a curved surface shape and are curved in a streamline shape in the vertical direction. The two side wall portions 13 and 13 are connected to the 3 rd side wall portion 121c or the 4 th side wall portion 121 d.
The front surface portion 11, the rear surface portion 12, and the end portions of the two side surface portions 13 and 13 opposite to the chamber 121 are connected to each other above the chamber 121 in the vertical direction. The front portion 11, the rear portion 12, and the two side portions 13 and 13 of the 2 nd fairing 10B are connected to each other below the chamber 121 in the vertical direction.
In addition, the front portion 11 is provided with a vent 15. The vent 15 is formed in an end portion of the front portion 11 opposite to the end portion on the compartment 121 side. That is, the vent 15 is formed at the upper end in the vertical direction of the front portion 11. The vent 15 of the 2 nd fairing 10B is formed at the lower end in the vertical direction of the front surface portion 11.
The back side portion 12 is provided with a back side exhaust port 16, and the side surface portion 13 is provided with a side exhaust port 17. The rear exhaust port 16 is formed at an end portion of the rear portion 12 on the compartment 121 side, i.e., a lower end portion in the vertical direction. The side exhaust port 17 is formed at an end portion of the side surface portion 13 on the compartment 121 side, that is, at a lower end portion in the vertical direction.
The vent 15 is formed at a position farther from the car chamber 121 than the rear exhaust port 16 and the side exhaust port 17, i.e., at an upper position in the vertical direction, i.e., at a side in the traveling direction when the car 120 moves upward. The opening area of the vent 15 is set to be equal to or slightly smaller than the opening area obtained by joining the back side exhaust port 16 and the side exhaust port 17. Further, a strainer for preventing foreign matter from entering the first cowling 10A may be provided in the vent hole 15.
In addition, in the 2 nd cowling 10B, the rear side exhaust port 16 and the side exhaust port 17 are formed in the upper end portions in the vertical direction of the rear side portion 12 and the side surface portion 13.
1-3. air flow during upward movement of the car
Next, the air flow when the car 120 having the above-described structure moves upward will be described with reference to fig. 4.
As shown in fig. 4, when the car 120 moves upward, the air W1 flowing around the car 120 flows along the rear surface portion 12 and the side surface portion 13 of the first rectification cover 10A to the rear surface side and the side surface side of the car 120. A part of the air W1 flows between the front surface portion 11 and the hall side wall surface 110a (hereinafter referred to simply as the front surface portion 11 side).
As described above, since the distance between the front portion 11 and the 1 st side wall portion 121a and the elevator shaft 110 is narrower than that between the other surfaces, the wind speed of the air W1 flowing through the front portion 11 is higher than that of the air W1 flowing through the other portions, and a positive pressure tends to be generated. Therefore, the air W1 flowing into the front surface portion 11 flows into the 1 st fairing 10A through the air vent 15. This prevents the air W1 from flowing between the 1 st side wall 121a provided with the door unit 122 and the hall side wall surface 110a, thereby preventing noise from being generated.
Further, the air W1 flowing into the 1 st fairing 10A is exhausted from the rear exhaust port 16 and the side exhaust port 17 to the outside of the rear portion 12 and the side portion 13 of the 1 st fairing 10A. In the compartment 121, the intervals T2, T3 between the 2 nd, 3 rd, and 4 th side walls 121b, 121c, and 121d, which are the back and side walls, and the walls 110b, 110c of the elevator shaft 110 are set to be sufficiently wide. Therefore, even if the air W1 flows to the back surface and the side surface of the compartment 121, noise is not easily generated.
The vent 15 is disposed at a position farther from the car chamber 121 than the back side exhaust port 16 and the side exhaust port 17, that is, at a side in the traveling direction of the car 120. This allows the air W1 flowing through the vent 15 to be smoothly discharged from the back side exhaust port 16 and the side exhaust port 17. In order to smoothly flow the air W1, the vent 15 may be connected to the back side exhaust port 16 and the side exhaust port 17 by piping, or a guide plate for guiding the air W1 to the back side exhaust port 16 and the side exhaust port 17 may be provided in the vent 15.
The opening area of the vent 15 is set to be equal to or slightly smaller than the opening area obtained by joining the back side exhaust port 16 and the side exhaust port 17. This makes it possible to equalize the flow rate of air flowing into the vent 15 with the flow rate of air discharged from the back side exhaust port 16 and the side exhaust port 17, and to smoothly flow the air W1.
When the car 120 moves downward, the air W1 around the car 120 flows from the front surface side to the back surface and the side surface side of the car 120 by the 2 nd rectification cover 10B. The air W1 flowing toward the front portion 11 of the 2 nd fairing 10B is discharged from the rear exhaust port 16 and the side exhaust port 17 through the vent 15 toward the rear and side portions of the car 120. Thus, even when the car 120 moves down, the air W1 can be prevented from flowing between the 1 st side wall 121a and the hall side wall surface 110a, and the generation of noise can be prevented.
Further, although the example in which the exhaust port is formed in the back surface portion 12 and the side surface portion 13 has been described, the present invention is not limited to this, and the exhaust port may be formed in only one of the back surface portion 12 and the side surface portion 13.
2. Embodiment 2
Next, a car according to embodiment 2 will be described with reference to fig. 5.
Fig. 5 is a perspective view showing the car according to embodiment 2.
The car 120B according to embodiment 2 is different from the car 120 according to embodiment 1 in the structure of the cowling. Therefore, the cowling will be described here, and the same reference numerals are given to the portions common to the car 120 according to embodiment 1, and redundant description will be omitted.
As shown in fig. 5, the car 120B includes a compartment 121, a door unit 122 provided on a 1 st side wall portion 121a of the compartment 121, a 1 st fairing 30A, and a 2 nd fairing 30B. The 1 st fairing 30A is provided at an upper portion of the compartment 121, and the 2 nd fairing 30B is provided at a lower portion of the compartment 121. Since the 1 st fairing 30A and the 2 nd fairing 30B have the same configuration, the 1 st fairing 30A will be described here.
The 1 st fairing 30A has a front surface portion 31 and two side surface portions 33, 33 opposed to each other. The top and rear sides of the 1 st fairing 30A in the vertical direction are open.
The front surface portion 31 and the two side surface portions 33 and 33 are formed in a flat plate shape. The front surface portion 31 faces the hall side wall surface 110a (see fig. 1), and is disposed substantially parallel to the 1 st side wall portion 121 a. The two side walls 33 and 33 are connected to the 3 rd side wall 121c or the 4 th side wall 121d, and are disposed substantially parallel to the 3 rd side wall 121c and the 4 th side wall 121 d. The front surface portion 31 and the two side surface portions 33 and 33 are arranged in parallel to the vertical direction.
The front portion 31 has an inclined surface 31a formed at an end opposite to the compartment 121, i.e., at an upper end in the vertical direction. The inclined surface 31a is inclined from the side of the front surface 31 facing the side wall surface 110a of the elevator hall to the back surface on the opposite side. Similarly, inclined surfaces 33a are formed at the upper end portions of the two side surface portions 33 in the vertical direction. The inclined surface 33a of the side surface portion 33 is inclined inward from the outside of the 1 st fairing 30A.
The front surface 31 is provided with an air vent 35. The vent 35 is formed at the upper end of the front portion 31 in the vertical direction. The side surface part 33 is provided with a side exhaust port 37. The side air outlet 37 is formed at the lower end of the side surface 33 in the vertical direction. The air vent 35 is formed closer to the traveling direction of the car 120B when it ascends than the side air outlet 37.
When the car 120 moves upward, the front surface portion 31 and the two side surface portions 33 and 33 cause the air W1 flowing around the car 120 to flow toward the back surface side of the car 120. A part of the air W1 flows between the front surface portion 31 and the hall side wall surface 110a (see fig. 1) (hereinafter, simply referred to as the front surface portion 31 side).
The air W1 flowing toward the front surface portion 31 passes through the air vent 35. Then, the air W1 passing through the air port 35 is exhausted from the opened rear surface side and side surface exhaust port 37 of the 1 st fairing 30. Since the entire rear surface side of the 1 st cowl 30 is open, the side surface portion 33 does not need to be provided with the side surface exhaust port 37.
The other structures are the same as those of the car 120 according to embodiment 1, and therefore, the description thereof is omitted. Even if the car 120B having the above-described configuration is used, the same operational effects as those of the car 120 according to embodiment 1 can be obtained.
The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention described in the claims.
In the car 120 according to embodiment 1, an example in which the 1 st fairing 10A and the 2 nd fairing 10B are formed in a dome shape having a flat surface portion on one surface has been described, but the invention is not limited to this. For example, the back surface portion 12 and the side surface portion 13 may be formed in a planar shape and disposed obliquely with respect to the vertical direction, or may be formed in other various shapes such as a shape having a recess near the dome-shaped top portion. The 1 st fairing 10A and the 2 nd fairing 10B may be provided with a front surface portion 11 facing at least the elevator hall side wall surface 110A and parallel to the direction in which the car 120 moves up and down. The front portion 11 may be provided with the vent 15.
In the above embodiment, the example in which the cowling is provided on each of the upper and lower portions of the compartment 121 has been described, but the present invention is not limited to this. For example, in an elevator that ascends at a high speed and descends at a low speed, a cowling may be provided only on the upper portion of the car chamber 121. In an elevator that descends at a high speed and ascends at a low speed, a cowling may be provided only in a lower portion of the car chamber 121. That is, the cowling may be provided only on one side of the upper portion and the lower portion of the car chamber 121 that moves at a high speed in the up-and-down movement.
In addition, when the elevator is reconstructed, the fairings with the structure are arranged at the upper part and the lower part of the compartment, thereby reducing the noise generated when the elevator car moves up and down. In addition, when an elevator having a cowl is modified, an air vent is formed in a front surface portion of the cowl, and an exhaust port is formed in a side surface portion or a rear surface portion of the cowl. Thereby, the same operation and effect as those of the elevator can be obtained.
In the present specification, terms such as "parallel" and "orthogonal" are used, but they do not mean "parallel" and "orthogonal" strictly, and include "parallel" and "orthogonal" and may be in a state of "approximately parallel" and "approximately orthogonal" within a range in which the functions thereof can be exhibited.
