The vanes 44 have an elongated shape extending in the width direction of the car room 11, and are arranged at intervals in the depth direction of the car room 11. Further, the slat 44 is inclined so as to face the front of the car room 11 as it goes downward of the car room 11.

  Therefore, the air blown toward the discharge port 42 in the casing 40 is inclined from the rear end of the ceiling surface 23 of the cab 11 toward the center of the cab 11 in the process of passing between the slats 44. Guided downward.

  As a result, in a state where the first blower 31 and the second blower 32 are operated, as shown by an arrow C in FIG. 1, from the rear end portion of the ceiling surface 23 of the cab 11 to the central portion of the cab 11. An air flow for ventilation is formed. Therefore, the passenger P who has entered the cab 11 is directly exposed to the flow of air blown out from the first supply port 36 and the second supply port 43 into the cab 11 mainly from the face to the upper body. Become.

  Further, the car 3 of this embodiment includes an exhaust port 45. The exhaust port 45 is an element for discharging the air in the car room 11 to the hoistway 2, and is opened in the ceiling surface 23 at a position just above the doorway 18, for example. For this reason, a part of the air blown obliquely downward from the rear end portion of the ceiling surface 23 of the cab 11 toward the central portion of the cab 11 is discharged to the hoistway 2 through the exhaust port 45.

  As shown in FIG. 2, a vertical operation panel 46 is disposed in the cab 11. The operation panel 46 is supported by the front plate 13 of the car 3 and is located on the right side of the doorway 18 when viewed from inside the car room 11.

  The operation panel 46 has a plurality of destination floor buttons 48 arranged on the face plate 47. The destination floor button 48 is an element for registering the destination floor of the car 3, and is registered as a destination floor by being operated by the passenger P who has entered the car room 11.

  Further, the operation panel 46 includes a close button 49 for closing the car door 17 that is open, an open button 50 for opening the car door 17 that is about to close, and an emergency button 51 for reporting to the management center in an emergency. The close button 49, the open button 50 and the emergency button 51 are disposed on the face plate 47.

  The operation panel 46 of the present embodiment includes a ventilation button 52 in addition to the various buttons 48, 49, 50, 51. The ventilation button 52 is an example of an operation unit, and activates the second blower 32 when it is artificially operated by a passenger P who has entered the cab 11. The operation button 52 is disposed on the face plate 47.

  FIG. 4 discloses an example of the ventilation button 52. The operation button 52 includes a square button frame 53, a character part 54 displayed as “ventilation”, and a display part 55 that emits light when the ventilation button 52 is operated.

  The button frame 53 is colored, for example, in blue to give an image of a refreshing feeling so that the presence of the ventilation button 52 becomes clear. The character part 54 and the display part 55 are arranged in an area surrounded by the button frame 53. For example, the character portion 54 is formed in a convex shape that forms a character in order to achieve both ease of touch and good touch feeling. The display unit 55 is positioned directly below the character unit 54, and when the ventilation button 52 is pressed by the passenger P, for example, it is lit with white light or blinks repeatedly.

  According to the present embodiment, at the time when the elevator 1 is operating normally, the first blower 31 maintains the operating state. That the elevator 1 is operating normally includes both when the car 3 is moving up and down and when the car 3 is landing on a specific landing 20. For this reason, during normal times, air in the hoistway 2 is blown to the car room 11 through the first supply port 36, and the ventilation of the car room 11 is ensured.

  On the other hand, since the elevator 1 is used by an unspecified number of people, for example, the smell of sweat of the passenger P, the smell of perfume, the smell of cigarette soaked in the clothes of the passenger P, or the bad smell of garbage brought by the passenger. It is possible to go into the cab 11. In the conventionally known deodorizing apparatus using ions, it takes several tens of minutes to lower the odor in the car room 11 to the extent that it does not matter, and an immediate deodorizing effect cannot be obtained.

  In the elevator 1 according to the present embodiment, the car room 11 is provided with a ventilation button 52. For this reason, when the passenger P gets into the car room 11 and is concerned about the smell in the car room 11, the passenger P voluntarily operates the ventilation button 52.

  Thereby, in addition to the 1st air blower 31 which is always operating, the 2nd air blower 32 starts operation, for example, after the ventilation button 52 is operated, the 1st air blower 31 and the 2nd Air in the hoistway 2 is forcibly taken into the cab 11 from both the blowers 32. In particular, since the car 3 according to the present embodiment has the exhaust port 45, the air permeability of the car room 11 is kept good, and the air in the hoistway 2 can be efficiently taken into the car room 11.

  As a result, the amount of air supplied to the car room 11 is doubled, and the odor component filled in the car room 11 can be quickly discharged from the exhaust port 45 to the hoistway 2 together with the air in the car room 11. Therefore, the deodorizing effect can be enhanced by replacing the air in the cab 11 within a short time.

  In addition, in the present embodiment, when the passenger P presses the ventilation button 52, the range from the face of the passenger P who gets into the cab 11 to the upper body extends from the first supply port 36 and the second supply port 43 to the cab 11 Exposed to the flow of air blown out. For this reason, the passenger P can directly feel the air flow in the cab 11 with his skin.

  At the same time, when the passenger P presses the ventilation button 52, the operation sound and wind noise of the second blower 32 are added to the operation sound and wind noise of the first blower 31, so that the passenger P in the cab 11 It can be heard audibly that the ventilation in the room 11 has started.

  Therefore, the odor in the cab 11 disappears instantaneously for the passenger P in the cab 11 due to the flow of the wind in the cab 11 and the increase in operating noise and wind noise of the two blowers 31 and 32. It is effective in producing a comfortable space in the car room 11.

  In addition, when the passenger P presses the ventilation button 52, the display unit 55 on the ventilation button 52 repeats lighting or blinking, so that the passenger P visually indicates that the ventilation of the cab 11 has been started. Can also be recognized.

  As a result, the passenger P in the cab 11 can feel an increase in the deodorizing effect in the cab 11 by the feeling of wind, hearing and vision, and the satisfaction of people using the elevator 1 can be increased. Become.
