The invention is described with reference to the accompanying drawings. Duplicate descriptions are appropriately simplified or omitted. In the drawings, the same reference numerals denote the same or equivalent parts.
Embodiment mode 1
Fig. 1 is a diagram showing an example of an elevator apparatus including a car 1 in embodiment 1. The elevator apparatus includes, for example, a car 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended from a hoistway 3 by a main rope 4.
The main ropes 4 are wound around a drive sheave 6 of the hoisting machine 5. The hoisting machine 5 is controlled by a control device 7. For example, the control device 7 controls the rotation and stop of the drive sheave 6. The car 1 moves in accordance with the rotation of the drive sheave 6. A door 9 is provided at a landing 8 where the car 1 stops.
The car 1 includes, for example, a car room 10, a door 11, and a motor 12. The cage 10 forms a space for passengers to board. The door 11 is driven by a motor 12. No means for driving the door 9 is provided at the landing 8. The doors 9 of the landing 8 are driven by a motor 12 via the doors 11 of the car 1.
Fig. 2 is a front view showing the car 1. Fig. 3 is a plan view showing the car 1. The car 1 includes, for example, a rail 13, a pulley 14, a fan 15, a belt 16, a coupling member 17a, a coupling member 17b, and a control panel 18, in addition to the car room 10, the door 11, and the motor 12. Fig. 2 shows an example in which the door 11 is in a double-opening manner. The door 11 has, for example, a panel 21, a panel 22, a hanger 23, a roller 24, a hanger 25, and a roller 26.
The car room 10 is formed with an entrance 10 a. The doorway 10a is opened and closed by a panel 21 and a panel 22. The hanger 23 is provided to the panel 21. The hanger 23 protrudes upward from the panel 21. The roller 24 is rotatably provided to the hanger 23. The rotation axis of the roller 24 is horizontally arranged. The hanger 25 is provided to the panel 22. The hanger 25 protrudes upward from the panel 22. The roller 26 is rotatably provided to the hanger 25. The axis of rotation of the roller 26 is parallel to the axis of rotation of the roller 24. The rotation axis of the roller 26 is horizontally arranged.
The rail 13 is disposed above the doorway 10 a. The rail 13 is horizontally disposed so as to cross above the doorway 10 a. A roller 24 is placed on the upper surface of the rail 13. The rollers 24 roll on the upper surface of the rail 13, thereby guiding the movement of the panel 21. Similarly, a roller 26 is placed on the upper surface of the rail 13. The rollers 26 roll on the upper surface of the rail 13, thereby guiding the movement of the panel 22.
The motor 12 is provided on the upper surface of the cage 10. The motor 12 has an output shaft 12 a. The motor 12 generates a force for driving the door 11 by rotating the output shaft 12 a. The output shaft 12a of the motor 12 is disposed above one end 13a of the rail 13, for example. The output shaft 12a is horizontally arranged. The output shaft 12a is disposed parallel to the rotation axis of the roller 24 and the rotation axis of the roller 26, for example.
The pulley 14 is rotatably provided to a member forming the car room 10. The pulley 14 is disposed above the other end 13b of the rail 13, for example. The rotation shaft of the pulley 14 is arranged in parallel with the output shaft 12a of the motor 12. That is, the rotation axis of the pulley 14 is arranged horizontally. The fan 15 is provided on the pulley 14. Therefore, when the pulley 14 rotates, the fan 15 rotates. If the pulley 14 does not rotate, the fan 15 does not rotate.
The belt 16 is wound around the output shaft 12a of the motor 12 and the pulley 14. The rotation of the output shaft 12a is transmitted to the pulley 14 via the belt 16. The pulley 14 is an example of a rotating body provided in the car room 10. The belt 16 is an example of a unit that transmits the rotation of the output shaft 12a to the rotating body.
In the example shown in the present embodiment, the output shaft 12a of the motor 12 and the rotation shaft of the pulley 14 are arranged horizontally. Therefore, the belt 16 wound around the output shaft 12a and the pulley 14 has an upper portion 16a and a lower portion 16 b. The connecting member 17a connects the upper portion 16a of the belt 16 and the panel 21. The coupling member 17b couples the lower portion 16b of the belt 16 and the panel 22.
The control panel 18 controls the devices of the car 1. For example, the control panel 18 controls the motor 12. The control panel 18 may control a lighting fixture 19 provided in the car 1. The control panel 18 may also control other devices.
The control panel 18 is provided on the upper surface of the car room 10. The control panel 18 is disposed, for example, at a position closer to the fan 15 than the motor 12. The control disk 18 has, for example, a housing 31. The housing 31 has air vents 31a and 31 b. The fan 15 is disposed opposite to the air vent 31 a.
In the elevator apparatus, for example, when the car 1 stops at the landing 8, the control panel 18 drives the motor 12. Thereby, for example, the output shaft 12a of the motor 12 rotates in the B direction. When the output shaft 12a of the motor 12 rotates in the B direction, the belt 16 moves. The upper portion 16a of the belt 16 moves to the right in fig. 2. The lower portion 16b of the belt 16 is moved to the left in fig. 2. Thereby, the door 11 is opened.
When the output shaft 12a of the motor 12 rotates in the B direction, the pulley 14 also rotates in the B direction. The pulley 14 rotates, and thereby the fan 15 rotates. As described above, the fan 15 faces the air vent 31 a. Therefore, for example, when the pulley 14 rotates in the direction B, air is blown from the fan 15 toward the air vent 31 a. When the pulley 14 rotates in the direction B, air outside the housing 31 enters the housing 31 through the air vent 31 a. The air inside the housing 31 is discharged from the vent 31b to the outside of the housing 31. That is, the fan 15 generates an air flow through the air vent 31a by the rotation of the pulley 14.
On the other hand, when the output shaft 12a of the motor 12 rotates in the direction C, the upper portion 16a of the belt 16 moves to the left in fig. 2. The lower portion 16b of the belt 16 moves to the right in fig. 2. Thereby, the door 11 is closed.
When the output shaft 12a of the motor 12 rotates in the C direction, the pulley 14 also rotates in the C direction. The pulley 14 rotates, and thereby the fan 15 rotates. For example, when the pulley 14 rotates in the direction C, an airflow from the air vent 31a toward the fan 15 is generated. Therefore, the air outside the housing 31 enters the inside of the housing 31 through the vent hole 31 b. Further, the air inside the housing 31 is discharged to the outside of the housing 31 through the vent hole 31 a. When the door 11 is closed, the fan 15 also generates an air flow through the air vent 31 a.
In the example shown in embodiment 1, the fan 15 is rotated, whereby the control board 18 is cooled. The force for driving the fan 15 is supplied from the motor 12. The car 1 does not have a dedicated power supply circuit and control circuit for driving the fan 15. Therefore, if the example shown in embodiment 1 is employed, the control panel 18 can be cooled by a simple mechanism.
In the example shown in embodiment 1, the fan 15 is rotated when the door 11 is opened and when it is closed. For example, in the case where the control panel 18 includes the semiconductor device 32 for driving the motor 12, the fan 15 can be rotated when the semiconductor device 32 generates heat. Therefore, the example shown in embodiment 1 is applied to the case where the control panel 18 has the semiconductor element 32.
In the example shown in the present embodiment, the fan 15 is provided on the pulley 14. This is an example. The fan 15 may be provided on a rotating body other than the pulley 14. In this case, the car 1 further includes a means for transmitting the rotation of the output shaft 12a of the motor 12 to the rotating body. In this example, the force for driving the fan 15 can be supplied from the motor 12.
Embodiment mode 2
Fig. 4 is a front view showing an example of the car 1 in embodiment 2. Fig. 5 is a plan view showing an example of the car 1 in embodiment 2. In the present embodiment, differences from the example disclosed in embodiment 1 will be described. Points not described in the present embodiment are the same as those in any of the examples disclosed in embodiment 1.
In the example shown in the present embodiment, the car 1 includes, for example, a car room 10, a door 11, a motor 12, a rail 13, a pulley 14, a fan 15, a belt 16, a coupling member 17a, a coupling member 17b, and a control panel 18.
The fan 15 is provided on the output shaft 12a of the motor 12. Therefore, when the output shaft 12a rotates, the fan 15 rotates. If the output shaft 12a does not rotate, the fan 15 does not rotate.
The control panel 18 is provided on the upper surface of the car room 10. The control panel 18 is disposed, for example, at a position closer to the fan 15 than the pulley 14. The fan 15 is disposed to face the air vent 31a formed in the housing 31.
In the example shown in the present embodiment, for example, when the car 1 stops at the landing 8, the motor 12 is also driven by the control panel 18. Thereby, for example, the output shaft 12a of the motor 12 rotates in the B direction. The output shaft 12a of the motor 12 rotates in the direction B, and the door 11 opens.
When the output shaft 12a of the motor 12 rotates in the B direction, the fan 15 also rotates. As described above, the fan 15 faces the air vent 31 a. Therefore, when the output shaft 12a rotates in the direction B, air is blown toward the air vent 31a from the fan 15, for example. When the output shaft 12a of the motor 12 rotates in the direction B, air outside the housing 31 enters the housing 31 through the air vent 31 a. The air inside the housing 31 is discharged from the vent 31b to the outside of the housing 31. That is, the fan 15 generates an air flow through the air vent 31a by the rotation of the output shaft 12 a.
On the other hand, the output shaft 12a of the motor 12 rotates in the C direction, whereby the door 11 is closed. When the output shaft 12a of the motor 12 rotates in the direction C, the fan 15 also rotates. For example, when the output shaft 12a rotates in the direction C, an airflow from the air vent 31a toward the fan 15 is generated. Therefore, the air outside the housing 31 enters the inside of the housing 31 through the vent hole 31 b. Further, the air inside the housing 31 is discharged to the outside of the housing 31 through the vent hole 31 a. When the door 11 is closed, the fan 15 also generates an air flow through the air vent 31 a.
In the example shown in the present embodiment, the fan 15 is rotated, whereby the control panel 18 is cooled. The force for driving the fan 15 is supplied from the motor 12. Therefore, if the example shown in embodiment 2 is employed, the control panel 18 can be cooled by a simple mechanism.
In the example shown in the present embodiment, the fan 15 is also rotated when the door 11 is opened and closed. Therefore, the example shown in the present embodiment is applied to the case where the control panel 18 has the semiconductor element 32.
Industrial applicability
The present invention can be applied to a car of an elevator having a control panel.
