Definitions

  • This disclosure relates to an indoor unit installation plate in an air conditioner mounted on an indoor wall.
  • the indoor unit of a wall-mounted air conditioner is installed on the wall via an installation plate attached to the wall of the room.
  • the installation plate is provided with a hole or a notch for pipe pulling out from the indoor unit to pass a pipe connected to the outdoor unit installed outdoors.
  • a hole or notch is provided, for example, on the lower outer periphery of the installation plate (see, for example, Patent Document 1).
  • embedded piping may be installed in which the piping for connecting the indoor unit and the outdoor unit is provided inside the wall.
  • the pipe may not always be connected at the center of the back side of the indoor unit, so that the pipe may be routed to the outside of the indoor unit.
  • the piping is exposed indoors, and the appearance of the room deteriorates. Therefore, recently, various methods have been proposed so that the pipe can be connected on the back side of the indoor unit by using the embedded pipe.
  • the first method to enable piping connection on the back side of the indoor unit is to avoid piping near the center of the lower part of the installation plate so that it can accommodate various pipe shapes or positions. This is a method of forming a large notch for the purpose in advance. However, in the first method, the notch portion is formed excessively with respect to the installation plate, so that the strength of the installation plate is lowered.
  • the second method of making it possible to connect the pipes on the back side of the indoor unit is a method of forming a perforated notch in the installation plate instead of the notch in the first method.
  • the installation plate is cut along the perforated notch, so that the piping can be connected on the back side of the indoor unit.
  • the blade of the tool it is difficult for the blade of the tool to enter when cutting the installation plate at the installation site of the indoor unit, so that the workability is deteriorated.
  • the present disclosure has been made in view of the above-mentioned problems in the prior art, and an object of the present disclosure is to provide an indoor unit installation plate capable of easily performing piping connection work while ensuring strength.
  • the indoor unit installation plate of the present disclosure is an indoor unit installation plate for installing an indoor unit connected to an outdoor unit to the wall via an embedded pipe provided in a wall of a house, and has a flat plate shape.
  • the hole enlargement portion adjacent to the pipe connection hole, a large pipe connection hole is previously provided so as to correspond to various shapes or positions of the embedded pipe. There is no need to set it up. Therefore, the strength of the installation plate can be ensured. Further, when it is desired to enlarge the pipe connection hole, the hole expansion portion can be easily cut to enlarge the pipe connection hole, so that the pipe connection work can be easily performed.
