Description

  The present invention relates to a structure for closing an air conditioning opening on an elevator car side plate, and more particularly to a structure for closing an air conditioning opening with a closing plate when an integrated air conditioner attached to the car side plate is removed.

2. Description of the Related Art As an elevator car air conditioner, an elevator unit in which an indoor unit and an outdoor unit are arranged in an upper part outside the car is known (for example, see Patent Document 1). In addition to this, there is also known an air conditioning unit that is disposed on a passenger car and includes a blower device that is connected to communicate with the air conditioning unit via a duct (see, for example, Patent Document 2). ).
Japanese Patent Laid-Open No. 5-319743 JP 2005-280901 A

  However, when an air conditioning unit or the like is placed on the upper part of the car as in the prior art described above, it is between the ceiling surface of the hoistway and the car upper part when the car is at the uppermost position of the hoistway. In some cases, the dimensions (overhead dimensions) have to be changed. In addition, since it is necessary to save the space above the car at the uppermost position, there are restrictions on the installation of air conditioning units and the like on the car. In addition, since various facilities are mounted on the car, it is problematic in design to additionally arrange an air conditioning unit.

  Therefore, when an integrated air conditioner is to be installed in a car, it is necessary to open an air conditioning opening (heat exchange air circulation port) on the side plate. For example, when an air conditioner is used as a cooler in summer and the air conditioner is removed at times other than summer, it is necessary to close the air circulation port.

  An object of the present invention is to provide a structure capable of easily and reliably closing an air conditioning opening by an operation in a car.

  A first feature of the present invention is for an elevator that is attached so that a rear surface side of an integrated air conditioner main body disposed on the passenger compartment side of an airflow port formed on a side plate of the elevator car is opposed to the air circulation port. A structure for closing an air conditioning opening of a car side plate that closes the air flow port with a closing plate when the air conditioner is removed, wherein the closing plate is located at a peripheral portion of the air flow port on the side plate. The gist of the invention is that a drop-off preventing piece for preventing the outside from falling off is provided, and a locking piece for locking to the outer peripheral edge of the air circulation port is provided outside the closing plate.

  A second feature of the present invention is for an elevator that is attached so that a rear surface side of an integrated air conditioner main body disposed on the passenger compartment side faces an air circulation port formed in a side plate of the elevator car. A structure for closing an air conditioning opening of a car side plate that closes the air flow port with a closing plate when the air conditioner is removed, wherein the closing plate is located at a peripheral portion of the air flow port on the side plate. The gist of the present invention is that a drop-off prevention piece for preventing the drop-out to the outside is provided, and a packing material is filled between the peripheral surface of the closing plate and the inner peripheral wall surface of the air circulation port.

  According to the present invention, when an air circulation port is formed on a side plate of a passenger car with respect to an existing passenger car, the air circulation port is easily and reliably closed with a closing plate when the air conditioner is removed. Can do.

  Hereinafter, the details of the closing structure of the air conditioning opening of the car side plate according to the embodiment of the present invention will be described with reference to the drawings. Prior to the description of the closing structure of the air conditioning opening of the car side plate of the present embodiment, the mounting structure of the elevator air conditioner will be described.

On the front surface of the air conditioner main body 40, there are a blow-out port for blowing cooling air to the lower part and an intake port for sucking air in the passenger compartment in the upper part.

  As shown in FIGS. 2 and 4, brackets 41 made of an L-shaped channel material are fixed to both sides of the air conditioner body 40 along the horizontal direction. As shown in FIG. 4, the horizontal plate portion 42 of the bracket 41 has a pair of mounting holes 42A, 42A at positions corresponding to the mounting holes 32A, 32A formed in the arm portion 32.

  As shown in FIG. 4, by mounting the bracket 41 on the arm portion 32, the air conditioner main body 40 can be attached to the mounting bracket 30, but between the bracket 41 and the arm portion 32, a buffer connection is provided. A member 43 is interposed. The buffer connection member 43 is provided with a buffer member 44 in the middle, and bolts 45 arranged coaxially with each other on both sides of the buffer member 44. As shown in FIG. 4, in the buffer connection member 43, the bolt portions 45 on both sides are inserted into the attachment holes 32 </ b> A of the arm portion 32 and the attachment holes 42 </ b> A of the horizontal plate portion 42. It is tightened.

  On the back surface side of the air conditioner main body 40, a filter (not shown) is arranged in a heat exchange air circulation port (not shown), and as shown in FIG. 4, a packing 48 is formed on the air circulation port and the side plate 10 on the back surface of the air conditioner main body 40. It is arranged so as to surround the air circulation port 11A.

  As shown in FIG. 1 and FIG. 2, the cover 50 is a housing that covers other than the back surface of the air conditioner body 40, and a blowout port (not shown) that blows out cooling air provided on the front surface of the air conditioner body 40. And a suction area 51 and an intake area 52 formed by collecting a plurality of holes in an area corresponding to a suction port (not shown).

  As shown in FIG. 2, the cover 50 has an L-shaped hook portion that is hooked on a cover locking piece 34 provided on the upper portion of the mounting bracket 30 at both side positions in the vicinity of the side plate 10 of the upper wall portion 53. 54 is provided. In addition, mounting pieces 56 are provided at both side positions near the side plate 10 of the bottom wall portion of the cover 50 so as to overlap the cover mounting pieces 33 provided at the lower portion of the mounting bracket 30. The attachment piece 56 is formed with a screw hole (not shown) that matches the screw hole 33A formed in the cover attachment piece 33. The cover 50 can be fixed so as not to be detached from the mounting bracket 30 by aligning the screw hole of the mounting piece 56 with the screw hole 33A of the cover mounting piece 33 and screwing the screw 57 together.
