Description

  The present invention relates to an outdoor unit of an air conditioner, and more particularly to a structure of an outdoor unit that can improve the flow of sucked air to improve the heat exchange rate and can easily attach and detach an electrical component box and check the interior.

As an outdoor unit of an air conditioner, there exists a thing as shown in FIG. 4, for example.
FIG. 4 shows the internal configuration of the outdoor unit from the side, and the inside of the housing 5 is partitioned into an upper space (heat exchange chamber) 7 and a lower space (machine room) 8 by a partition plate 6. 1 includes a compressor 2 attached to a frame 1 and a front panel 16 provided on the front surface. The heat exchange chamber 7 is provided with a blower 10 in the upper part thereof, a heat exchanger 9 in which the lower part is positioned rearward and the upper part is inclined forward, and a control box (electric component box) 13 is provided in front of the heat exchange chamber 7. The inverter case 13 can be inspected by disposing it and providing a front guard 14 in the form of a lattice on the front side and removing the front guard 14 (see, for example, Patent Document 1).

  However, in the thing of the said structure, there existed a possibility that the air flow which goes to the heat exchanger 9 from a front may be disturbed by the inverter case 13, and may exert a bad influence on heat exchange. Therefore, an outdoor unit as shown in FIG. 5 has been developed to solve such problems. In this outdoor unit, by providing an electrical component box 13 with a heat sink 13a on one side of the housing 5, the air flow from the front to the heat exchanger 9 is improved, and the internal inspection of the electrical component box 13 is performed. The side plate 4a is removed to carry out.

  By the way, even one outdoor unit provided with a plurality of compressors (one having a constant rotational speed and an inverter type capable of controlling the rotational speed) 2 as shown in FIG. 5 can support a plurality of indoor units. However, in some cases, when a plurality of outdoor units are installed close to each other as shown in FIG. 5 or when there is a wall on the side even when there is only one outdoor unit, the side plate 4a can be attached and detached. There was a problem that the internal inspection of the electrical component box 13 could not be performed.

Japanese Utility Model Publication No. 5-69539 (2nd page, FIG. 2)

As described above, in the conventional outdoor unit, there is a problem that the air flow inside the housing is deteriorated depending on the mounting position of the electrical component box, or the internal inspection of the electrical component box becomes difficult.
Accordingly, an object of the present invention is to provide an outdoor unit for an air conditioner that can solve the above-described problems.

  The present invention has been made to solve the above-mentioned problems, and a partition plate for vertically partitioning the interior of the housing is provided inside the housing, and a heat exchange chamber provided with a heat exchanger is formed on the partition plate. In addition to a machine room provided with a compressor or the like at the bottom, an electrical component box is disposed on one side of the housing, and the electrical component box can be attached and detached from the front of the housing. The configuration.

  Further, the removed electrical component box can be laid on the partition plate.

  Further, the electrical component box is configured to be supported by the heat exchanger and the partition plate.

  In the case of an outdoor unit of an air conditioner having the configuration of the present invention, since the electrical component box is located on one side inside the housing, the air flow from the suction port at the upper front to the heat exchanger is improved, While the exchange rate is improved, when performing an internal inspection of the electrical component box, if there are no obstructing walls on the side, remove the side plate of the housing and open the lid of the electrical component box from the outside of the side. If inspection is possible and inspection from the outside of the side is impossible, the inverter case can be easily removed by removing the ventilation panel (or front guard) provided at the top front of the chassis. Since the removed inverter case can be laid on a partition plate provided inside the housing, the internal inspection can be easily performed, and the restriction on the installation location of the outdoor unit can be eliminated.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows a schematic configuration of an outdoor unit of an air conditioner. In the figure, 1 is a housing. The housing 1 includes a front guard 2 formed in a lattice shape, a pair of left and right front panels 3, a side plate 4, a bottom plate 5, a pair of left and right top plates 7 provided with a fan guard 6 on the top, It is composed of a frame 8 and the like that can be attached, and in the housing 1, there are two blowers not shown in the upper part. In the lower space, the lower part is located rearward and the upper part is inclined forward. There is a heat exchanger 9 and a second heat exchanger 10 is erected on the rear side.

  A partition plate 11 is provided in front of the heat exchanger 9 to partition the interior of the housing 1 up and down, a heat exchange chamber 12 is formed in the upper portion, a machine chamber 13 is formed in the lower portion, and the machine chamber 13 has a plurality of compressors. (A compressor 14 having a constant rotational speed and a compressor 15 capable of controlling the rotational speed) and other devices not shown are disposed. An electrical component box 16 that houses electrical components is provided on one side of the housing 1. A lid 16a is placed on the opening surface of the electrical component box 16, and is fixed with a plurality of screws 17 so as to be opened and closed. The electrical component box 16 itself is fixed with a plurality of screws 18 separately prepared so that it can be attached and detached from the front surface of the housing 1. Reference numeral 19 denotes a heat sink protruding from the lower part of the electrical component box 16.

  FIG. 2 is an enlarged view of the mounting state of the electrical component box 16. The mounting plate has two front positions on the inner surface of the frame 8 and a rear mounting piece 16 b on one side front of the heat exchanger 9. 20 are fixed with screws 18 respectively, and the end face of the heat sink 19 is pressed by using the screws 18 and the fixtures 21 to restrict lateral movement. In addition, one side of the partition plate 11 is in a state in which a portion necessary for attaching and detaching the electrical component box 16 is cut, and when the internal inspection of the electrical component box 16 is performed, the four screws described above are used. It can be taken out by removing 18 and moving the electrical component box 16 in the horizontal direction (left direction) as shown by the arrow and then pulling it upward.

  FIG. 3 is an enlarged view of the portion related to the present invention, as in FIG. 2. The electrical component box 16 taken out from a predetermined position is mounted on the partition plate 11 with the heat sink 19 down as shown in FIG. If all the screws 17 are removed, the lid 16a is removed, and the internal inspection can be performed.
