Description

[Detailed description of the invention] (a) Industrial application field This invention relates to an outdoor unit of a separate air conditioner that is used by connecting the indoor unit to the refrigerant piping and power cord.

(b) Prior art In conventional outdoor units, the mounting box for the piping connection valve is firmly fixed to the bottom plate by welding or screwing, and the power cord is taken out through an opening drilled in the service panel. It was common. For this reason, it was necessary to fix the power cord extraction plate inside the unit so that the service panel could be removed without regard to the power cord during service inspection.

(c) Purpose of the invention In view of these points, this invention aims to omit the parts that fix the power cord outlet plate, improve workability, and increase the strength of the exterior panel for the outdoor side of a separate type air conditioner. The aim is to provide units.

(d) Structure of the invention The outdoor unit of this invention consists of an exterior panel that stands up on the bottom plate of the unit, a mounting box for the piping connection valve that protrudes outward from the unit, and an outlet for the power cord that protrudes from the edge of this box. a component holder having a plate, the side edges of the mounting box and the extraction plate being joined to the stepped edge of the exterior panel, the lower edge being fixed to the bottom plate and the upper edge being fixed to the exterior panel; By providing a service panel that is mounted across the bottom plate and the exterior panel, the power cord outlet plate is integrated with the piping connection valve mounting box, thereby eliminating parts. The component mounting tool and the exterior panel are mutually reinforced.

(e) Embodiment An embodiment of the present invention will be explained based on the drawings. Fig. 1 is a perspective view of the outdoor unit, and Fig. 2 is an exploded perspective view of the main parts of the outdoor unit. The structure is such that outdoor air is sucked in through the intake grilles 2 and discharged forward through the exhaust nozzle holes 4 of the front plate 3.

5 is the bottom plate of the unit with the peripheral edge 6 raised; an L-shaped plate-fin type heat exchanger (not shown) is installed on the intake grille on the back 1 and side 2, and a compressor (not shown) is installed inside the exterior panel 7. (2) are placed along each other, and an axial flow fan (not shown) facing the exhaust nozzle hole 4 is used to draw in outside air and discharge it as described above.

The front plate 3 and the top plate 8 are previously formed integrally by spot welding, and the exterior panel 7 has two upper edges connected to the flange piece 9 of the top plate 8 and the screws 10.
10, the screw hole 11 on the lower edge is screwed into the screw hole 12 on the peripheral edge 6 of the bottom plate 5 with a screw 13, so that it is erected on the bottom plate 5.

Reference numeral 14 denotes a component fixture made of sheet metal, which includes a mounting box 16 for the piping connection valves 15, 15 that protrudes outward from the unit, and power cords 18, 18 that are bent integrally from the edge 17 of this box and extend upward. The mounting box 16 and the right side bent side edges 20 and 21 of the extraction plate 19 are joined to the stepped edge 22 of the exterior panel 7, which has a U-shaped cross section, and are connected to the screw hole in the lower edge 23. 24 and 24 are screwed into the screw holes 25 and 25 on the peripheral edge 6 of the bottom plate 5, and the screw hole 27 on the upper edge 26 is screwed and fixed to the nut part 28 of the stepped edge 22 of the exterior panel 7, so that the exterior panel 7 and the component mount 14 are designed to reinforce each other.

Reference numeral 29 denotes a service panel adjacent to the fixture 14, whose upper edge 30 is inserted into the inside of the flange piece 9 of the top plate 8, and which is installed across the bottom plate 5 and the exterior panel 7, and has an L-shaped notch. The edge 31 overlaps the upper edge 26 and left side edge 32 of the fixture 14, and the left and right bent pieces 33, 34 are attached to the step edges 22, 35 of the exterior panel 7 and front plate 3, which have a U-shaped cross section, as shown in FIG. The threaded hole 36 is connected to the nut part 37 of the stepped edge 35.
Then, the screw hole 38 is screwed into the screw hole 39 of the fixture 14, and the screw hole 40 is screwed into the screw hole 41 of the peripheral edge 6 of the bottom plate 5 with screws 42, respectively.

After placing the compressor, heat exchanger, etc. on the bottom plate 5 in this way, the exterior panel 7 is fixed to the integral part of the front plate 3 and the top plate 8, and is screwed to the bottom plate 5. 2, an intake grill is provided, and the parts mounting tool 14 is provided astride the bottom plate 5 and the exterior panel 7.
and attach the pipe connection valve 1 to the mounting holes 43, 43.
5 and 15 are fixed and the service panel 29 is attached, the assembly work is completed. If the product is shipped in this condition and installation work is performed on site, service panel 2
After removing the power cord 18, which is connected to the electrical equipment (not shown) facing the service opening 44,
18 from the extraction holes 45, 45, and remove the extraction plate 1.
9 with fasteners 46, 46, and connect the inter-unit refrigerant piping 47, 47 connected to the indoor unit (not shown) to the piping connection valves 15, 15, and install the service panel 29. The installation work will be completed. In this installation state, the power cords 18, 18 are bent comfortably within the protruding dimensions of the mounting box 16, so that they are lined up with the refrigerant pipes 47, 47 and have a good-looking finish, and can be inserted from the gap between the service panel 29. Even if rainwater enters, it is guided downward by the stepped edges 22, 35 having a U-shaped cross section, so that the electrical components facing the service opening 44 will not get wet.

(f) Effects of the invention According to the invention, the power cord outlet plate is integrated with the mounting box of the piping connection valve, so there is no need to separately install and fix it like in conventional units, reducing parts and labor. It is possible to improve sexual performance.

In addition, the mounting box for the piping connection valve has a box shape so that it has its own strength, and the flat plate-shaped exterior panel has stepped edges so that it has its own strength. By combining the component mount with the power cord take-out plate integrated with the exterior panel, the component mount and the exterior panel can be mutually reinforced and have a stronger assembly structure.

Moreover, by removing the service panel, the electrical components and power cord inside the unit can be easily installed and inspected through the wide service opening.
