Definitions

  • the present invention relates to an outdoor unit for an air conditioner, and particularly, to an outdoor unit for an air conditioner in which a mounting structure of an option board is improved.
  • an inside of a housing of the outdoor unit is partitioned by using a partition plate into a compressor chamber in which a compressor and the like are disposed and a blower chamber in which a blower and an outdoor heat exchanger are disposed.
  • a box-shaped electric component box for housing electric components such as a control board is disposed on an upper end portion of the partition plate so as to straddle the compressor chamber and the blower chamber.
  • an option board for function enhancement is mounted inside the electric component box of the outdoor unit with a conventional structure to respond to the request (see Japanese Patent Application Laid-open No. 2003- 294272 (Patent Document 1)).
  • Patent Document 1 Japanese Patent Application Laid-open No. 2003- 294272
  • a space for housing the option board is al so required, which increases the electric component box in size.
  • Patent Document 2 Japanese Patent Application Laid-open No. 6-2890
  • the present invention has been made in consideration of the above-described circumstances, and it is an object of the invention to provide an outdoor unit for an air conditioner in which addition and replacement of an option board can be easily done.
  • an outdoor unit for an air conditioner including:
  • an option board housing box is formed into a box by bending a sheet metal and is composed of a bottom surface on which the option board is placed, a rear surface, left and right side surfaces, and fixing chips extending from the left and right side surfaces.
  • the option board is housed in a box which is substantially opened at side surface facing a bottom surface portion of the electric component box.
  • the outdoor unit for the air conditioner of the present invention it is possible to provide the outdoor unit for the air conditioner in which the operations for adding and replacing the option board become easy.
  • the option board housing box is provided to the lower surface portion of the outside of the electric component box. Therefore, the option board is less susceptible to heat from an outdoor control board and an inverter board, and designing is easier as compared with a case where the option board is mounted inside. Moreover, it is not necessary to consider a waterproof property of the option board housing box so much. Furthermore, the structure of the option board housing box can be simplified, and therefore, manufacturing cost can be reduced.
  • the mounting chip obstructs a view of the option board from the front, which prevents an accidental setting change of the option board.
  • the outdoor unit 1 for the air conditioner of the present embodiment includes an outdoor unit housing 2.
  • the outdoor unit housing 2 includes a bottom plate 3, a front plate 4 standing up from the bottom plate 3 and formed with an air outlet 4a, a side plate 5 connected to the front plate 4 and rising from the bottom plate 3 so as to reach and cover a rear side end portion 14a of a heat exchanger 14, a column 6 standing up from the bottom plate 3 so as to face a corner portion of the heat exchanger 14, and a top plate 7 placed to cover an upper opening defined by the front plate 4, the side plate 5 and the column 6.
  • a wire guard for protecting the heat exchanger 14 is provided over the side plate 5, the column 6, and the front plate 4 to face the heat exchanger 14.
  • the front plate 4 is divided to provide a service panel 8. By detaching the service panel 8, an inside of a machine chamber 12, which will be described later, is exposed. Moreover, a fan guard 4b is mounted to the air outlet 4a of the front plate 4.
  • a front piping panel 9a for leading the piping into the machine chamber 12, which will be described later, at a site of installation is provided to a front lower corner portion of the outdoor unit housing 2.
  • a rear piping panel 9b is provided at a lower portion of one side surface.
  • an inside of the outdoor unit housing 2 is partitioned into a heat exchanger chamber 11 and a machine chamber 12 by a partition plate 10.
  • the heat exchanger 14 is in an L-shape in a plan view to face a rear surface and one side surface of the outdoor unit 1 with the rear side end portion 14a thereof being fixed to the side plate 5 and the front side end portion 14b thereof being fixed to the front plate 4.
  • the blower 13 is mounted to a motor base 15 with its lower portion fixed to the bottom plate 3, one end of its upper portion fixed to a rear side of the top plate 7, and the other end thereof fixed to the front plate 4.
  • a compressor 16, an accumulator 17, a piping connecting valve 18 at the site, an electric component box 20, refrigerant piping, and the like are housed while placed on the bottom plate 3.
  • the electric component box 20 is provided in the machine chamber 12 near an upper portion of the partition plate 10, and a duct 19 through which air after cooling the electric component box 20 flows is provided to an upper portion of the heat exchanger chamber 11 near the upper portion of the partition plate 10.
  • a rear piping panel 9b provided to a lower corner portion of the outdoor unit housing 2, an air vent 9c for taking outside air into the machine chamber 12 is formed.
  • the site piping connecting valve 18 and the electric component box 20 are disposed so as to face the service panel 8. By detaching the service panel 8, it is possible to easily perform operations such as a maintenance check.
  • the electric component box 20 is in a box shape formed with an air inlet 20a (Fig. 3) for cooling electric components and a air outlet 20b communicating with a duct 19.
  • a terminal block 21 and an outdoor control board 22a are mounted on a front surface 20c.
  • a compressor driving control board (inverter) 22b is housed in the electric component box 20.
  • a mounting chip 20e extending downward from a lower surface 20d of the electric component box 20 is provided to the front surface 20c of the electric component box 20 so that an option board housing box 23 for function enhancement can be mounted outside (i.e., on a side opposite to the electric component box) the lower surface 20d.
  • the option board housing box 23 is a box formed by bending a sheet metal and is composed a bottom surface 23a on which an option board 24 is placed, a rear surface 23b, left and right side surfaces 23c, 23d, and fixing chips 23c1 and 23d 1 extending from the left and right side surfaces. A portion facing the lower surface 20d and the mounting chip 20e of the electric component box 20 are substantially opened outward.
  • the option board housing box 23 is mounted to an outside of the lower surface 20d of the electric component box 20 by fixing the fixing chips 23c1, 23d1 provided to the side surfaces 23c, 23d to the mounting chip 20e of the electric component box 20 by means of screws or the like.
  • the option board housing box 23 is provided with an option board fixture 23e and a wiring guide portion 23f.
  • the option board housing box 23 is provided to the lower surface portion of the outside of the electric component box 20. Therefore, the option board 24 is less susceptible to heat from the outdoor control board 22a and an inverter board 22b, and the option board can be easily designed as compared with a case where the option board 24 is mounted inside. Moreover, it is not necessary to consider a waterproof property of the option board housing box 23 so much. Furthermore, the structure of the option housing box 23 can be simplified, and therefore, the cost can be reduced.
  • the mounting chip 20e obstructs a view of the option board 24 from the front side, so that an accidental setting change of the option board 24 is prevented.
  • the service panel 8 provided at the front of the outdoor unit housing 2 is detached to expose the electric component box 20 as shown in Fig. 3.
  • the option board housing box 23 mounted to the lower surface 20d of the electric component box 20 can be detached easily, and it is possible to easily add or replace the option board 24 in the option board housing box 23.
  • the operations for adding and replacing the option board become easy, the outdoor unit can be miniaturized due to miniaturization of the electric component box, the cost can be reduced due to the miniaturization, and it is possible to achieve the outdoor unit for the air conditioner having the option board less susceptible to heat generated from the electric components.
