Description

  The present invention relates to an outdoor unit of an air conditioner used for temperature adjustment of indoor air in cooperation with an indoor unit installed on an indoor wall surface or the like.

  For example, as shown in FIG. 6, this type of outdoor unit is a compressor 2 that compresses refrigerant in a steel housing that is inexpensive and excellent in strength. During cooling operation, the refrigerant dissipates heat to the surrounding air and condenses. In addition, a heat exchanger 3 in which the refrigerant absorbs heat from the surrounding air and evaporates during heating operation, a blower 4 that takes outside air into the housing and blows it to the heat transfer fins of the heat exchanger, and the like are provided.

The blower 4 is supported and housed by a support 6 having one end fixed to the bottom plate 5 of the housing and the other end hooked to the heat exchanger 3 (see, for example, Patent Document 1).
JP 2003-148770 A

  In the outdoor unit of an air conditioner proposed in Patent Document 1, one end of the column supporting the blower is fixed to the bottom plate of the housing, and the other end is hooked to the upper end of the heat exchanger. Therefore, when it was necessary to remove the heat exchanger for maintenance and inspection of the heat exchanger, it was necessary to remove the support supporting the blower.

  In addition, there is a problem that it is difficult to reduce the manufacturing cost because it is necessary to use a long steel material for the support supporting the blower. That is, as long as the blower can be reliably supported, the blower mounting member only needs to have dimensions that allow the blower to be mounted at a predetermined height, and the portion above the portion where the blower is mounted is a useless portion. .

  Although the blower mounting member is partially provided with an opening by punching, this contributes to reducing the weight of the outdoor unit, but the steel pieces obtained by cutting must be sold as iron scrap. Hardly contributes to the reduction of the manufacturing cost of the machine.

  Therefore, it is necessary to make it possible to support the blower independently of the heat exchanger and to support the blower reliably even with a short member, which has been a problem to be solved.

  In order to solve the above-described problems of the prior art, the present invention provides an air conditioner outdoor unit equipped with a refrigerant compressor, a heat exchanger, and a blower in a casing, and a column for mounting the blower is erected on the bottom plate of the casing. The other end of the inclined reinforcing member that is attached to one end of the bottom plate inclined portion between the bottom plate shelf formed by drawing the bottom plate in the middle of the column and the bottom plate bottom without change in shape and screwed to the bottom plate The main feature is that they are connected.

  According to the present invention, it is possible to support the blower reliably in a form independent of the heat exchanger, even if it is a short column fixed only to the bottom plate of the housing at the lower end side, and by reducing the number of members used Also, the manufacturing cost can be reduced. In addition, since the other end of the inclined reinforcing member, which has one end attached to the bottom plate inclined portion and screwed to the bottom plate, is fixed to the middle portion and the column is reinforced, there is no backlash during transportation or operation.

  The lower end of the inclined reinforcing member made of a flap formed by cutting and raising the flat plate portion of the post, which is screwed to the bottom plate of the housing through the front horizontal plate portion of the lower end portion formed by bending the support column supporting the blower forward An outdoor unit of an air conditioner in which a portion is screwed and fixed to the bottom plate along a bottom plate inclined portion formed by press molding of the bottom plate.

  An embodiment of the present invention will be described with reference to FIGS. In order to facilitate understanding, in these drawings, parts having the same functions as those described with reference to FIG.

  Also in the outdoor unit 100 of the present invention, as shown in FIG. 4, a compressor 2 for compressing a refrigerant, a heat exchanger 3, and a blower 4 are provided inside a steel housing 1. . The heat exchanger 3 is formed and arranged in a substantially L shape when viewed from above, and the refrigerant flowing through the heat transfer tube of the heat exchanger 3 and the air taken in from the outside by the blower 4 Heat exchange efficiency is enhanced.

  The blower 4 is mounted on the upper side of a support 6 in which the lower side is screwed and fixed to the bottom plate 5 of the housing 1. The support 6 is manufactured by machining an appropriate high-strength member having a U-shaped cross section, such as a steel plate.

  That is, for example, as shown in FIG. 3, a rectangular connecting piece 7 and a standing U-shaped piece 8, 9 which stands up along the long side of the connecting piece 7 and is placed opposite to each other in parallel. The corners 10 and 11 at one end are cut to form the flaps 12, 13, and 14.

  Each flap is bent 90 degrees in the direction of the outside (in the following description, the side surrounded by a U-shaped section by each piece is referred to as the inside and the opposite side is referred to as the outside). Part 12A and horizontal horizontal plate parts 13A, 14A are formed.

  Note that a downwardly inclined portion 12C is provided at the tip of the flap 12 functioning as the front horizontal plate portion 12A, and a male screw portion of the screw 20 can be loosely inserted into the downward inclined portion 12C and the horizontal horizontal plate portions 13A and 14A. Open screw holes 12B, 13B, 14B.

  Further, a substantially U-shaped cutting process is performed on the central portion of the connecting piece 7 to form a flap 15 connected to the remaining portion of the connecting piece 7 on one end side of the connecting piece 7, and the flap 15 is connected to the connecting piece 7. The inclined reinforcing member 15A is formed by being erected on the inner side of 7 and further rotated by about 40 to 60 degrees, for example, 50 degrees from the standing state toward one end of the connecting piece 7.

  Further, the portion of the inclined reinforcing member 15A made of the flap 15 is also subjected to a substantially U-shaped cutting process so that the flap 16 connected to the remaining portion of the inclined reinforcing member 15A on the tip 15B side of the inclined reinforcing member 15A is provided. The front horizontal plate portion 16A is formed by causing the flap 16 to be parallel to the front horizontal plate portion 12A and the like on the connecting piece 7 side, and the front horizontal plate portion 16A has a male screw portion of the screw 20. A screw hole 16B into which can be freely inserted is opened.

  Note that the screw hole 16B opened in the front horizontal plate portion 16A is formed through an opening 15C formed in the inclined reinforcing member 15A made of the flap 15 when the flap 16 is raised to form the front horizontal plate portion 16A. The screw 20 is provided at a position where the screw 20 can be screwed in or removed while checking from the other end side of the connecting piece 7.

  Furthermore, the support | pillar 6 is formed by opening the air blower attachment hole 17 for attaching the air blower 4 to the other end side of the connection piece 7. FIG. In addition, when actually making the support | pillar 6, as shown in FIG.1 and FIG.2, the inclination reinforcement member which provides the flange 7B around the opening part 7A formed in the connection piece 7 at the time of formation of the flap 15 is shown. The bending rigidity of the member can be improved by forming the ridge 15D on 15A.

  On the other hand, on the bottom plate 5 of the housing 1, a plurality of shelves for placing devices are dispersedly installed by press working. Moreover, the bending rigidity of the baseplate 5 is improved by disperse | distributing and installing these several shelf parts. That is, the bottom plate 5 includes a bottom plate bottom portion 5A that is formed lowest, a bottom plate shelf portion 5B that is formed higher than the bottom plate bottom portion 5A, and an inclined bottom plate inclined portion 5C.
