  • Control equipment 23 for controlling the operation of the elevator is received within the case 21. Further, gaps are defined between the inspection door 9 and the case 21 and at both sides of the case 21, and those gaps constitute an air duct portion 24.
  • air within the hoistway 1 is made to flow into the case 21 from the air inlet 21a through the air duct portion 24 by driving the cooling fan 22.
  • the air that flows into the case 21 is exhausted to the exterior of the case 21 from the air outlet 21b after the control equipment 23 is cooled. Then, the air is returned to the hoistway 1 through the air duct portion 24.
  • the control equipment 23 catches fire, and flames are blown to the exterior of the case 10 from the air inlet 21a or the air outlet 21b, since the air duct portion 24 having sufficient length and forms the bent path indicated by the arrows in Fig. 2, is disposed between both the air inlet 21a and air outlet 21b and the hoist space 6, flames are prevented from reaching the hoist space 6, and fire is prevented from spreading to the upper floors.
  • the gap around the case 10 is utilized as the air duct portion 24, it is unnecessary to provide a member which forms the air duct within the case 10, so that space within the case 10 can be effectively utilized.
  • Fig. 3 is a front view showing an elevator controlling apparatus in accordance with a second embodiment of the present invention.
  • a space between the case 21 and the inspection door 9 is partially filled with a plurality of incombustible (fire resistant) members 25 which surround the air inlet 21a and the air outlet 21b except for the lower portion.
  • the incombustible members 25 may be attached to the case 21 or the inspection door 9.
  • Other structures are identical with those in the first embodiment.
  • Fig. 4 is a front view showing an elevator controlling apparatus in accordance with a third embodiment of the present invention.
  • a plurality of reinforcement members 26 made of an incombustible material are formed integrally with or fixed onto the back surface of the inspection door 9.
  • the reinforcement members 26 contact the case 21 whereby the periphery of the air inlet 21a and the air outlet 21b except for the lower portion is surrounded by the reinforcement members 26.

  • a case 31 made of an incombustible (fire resistant) material is disposed within the installation chamber 8.
  • An air inlet 31a as a vent hole is disposed on the bottom portion of the case 31.
  • an air outlet 31b as a vent hole which faces the hoist space 6 is disposed on the case 31.
  • Control equipment 32 for controlling the operation of the elevator and a cylindrical member (duct) 33 as an air duct portion are received within the case 31.
  • One end portion (lower portion) 33a of the cylindrical member 33 is connected to the air outlet 31b. Also, the other end portion (upper portion) 33b of the cylindrical member 33 is disposed above the one end portion 33a. In addition, a substantially Z-shaped bent portion 33c is disposed on the middle portion of the cylindrical member 33.
  • a cooling fan 34 which faces the other end portion 33b of the cylindrical member 33 is disposed within the case 31.
  • radiating fins 35 which are connected to the control equipment 32 such as a power device or a device that generates heat are disposed between the cooling fan 34 and the other end portion 33b of the cylindrical member 33.
  • the cylindrical member 33 is partially filled with an incombustible member (fire resistant material) 36, such as steel wool, that is air permeable.
  • a plate-like shield body (shutter) 37 for opening and closing the air outlet 31b and a pair of guides 38a and 38b for guiding the movement of the shield body 37 are disposed on the outer peripheral portion of the case 31.
  • the shield body 37 is held normally by a holding member 39 at a position where the air outlet 31b is opened.
  • the holding member 39 is made of a low-melting-point material such as a low-melting-point metal, for example, solder. Also, one end portion of the holding member 39 is connected to the shield body 37, and the other end portion of the holding member 39 is drawn within the case 31 and fixed to the inner wall portion of the cylindrical member 33. If the holding member 39 is melted and cut by a fire, the shield body 37 drops by its own weight, and the air outlet 31b is closed.
  • air is drawn into the case 31 from the air inlet 31a by driving the cooling fan 34.

  • the bent portion 33c is disposed along the cylindrical member 33, the distance up to the air outlet 31b can be lengthened, thereby preventing flames from reaching the air outlet 31b. Still further, because the porous incombustible member 36 is disposed within the cylindrical member 33, flame progress is further suppressed.
  • the holding member 39 is melted and breaks to close the air outlet 31b when the interior within the cylindrical member 33 increases in temperature due to a fire or the like, flames are more surely prevented from being blown out from the air outlet 31b.
  • the wall portion of the installation chamber 8 at the elevator hall 2 side is not heated by air flow exhausted (heated air) during normal times.
  • the installation space 7 is disposed to be adjacent to the elevator hall 2 side of the door pocket space 5.
  • the present invention is also applicable to any controlling apparatus located in an installation space from which a fire may spread through the hoist space 6.
