BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an outdoor unit in a separate type air conditioner having an indoor unit and an outdoor unit installed separately, and more particularly to fixing of the outdoor unit main body and its top plate.
BACKGROUND ART
In an outdoor unit of a conventional separate type air conditioner of this type, as shown in a perspective view in FIG. 6, constituent members disposed in the upper part of an outdoor unit main body 1, such as inner and outer connection piping junctions and electrical parts, are covered by a top plate 2 so as to isolate from the outside.
To fix the outdoor unit main body 1 and top plate 2, as shown in FIG. 7, the side of the top plate 2 was fixed to the side wall of the outdoor unit main body 1 with a screw 3, or, as shown in FIG. 8, the top plate 2 was fixed to the outdoor unit main body 1 with the screw 3 on its upper surface.
In such conventional constitution, however, when installing the outdoor unit of the separate type air conditioner on the verandah or other outside place, in the constitution as shown in FIG. 7, for example, when it is easy to work from above the top plate, its fixing job is difficult because there is a screw fixing part at the side of the top plate 2. Or, in the constitution shown in FIG. 8, since the screw fixing part is located on the same level as the upper surface of the top plate 2 installed horizontally, it is likely to impair the appearance by corrosion of screw due to rainfall, invasion of rainwater into the mechanism, or protrusion of screw head to outside.
The invention is intended to solve such conventional problems, and it is hence an object thereof to present an outdoor unit of separate type air conditioner capable of eliminating troubles such as staying of water around screw, corrosion of screw, invasion of water into machine, or protrusion of screw to outside, without sacrificing the working efficiency of screw fixing of outdoor unit main body and top plate.
SUMMARY OF THE INVENTION
To achieve the object, the outdoor unit of the separate type air conditioner of the invention is characterized by inclining the screw fixing part of the upper surface of the top plate at the time of installation so as to discharge water smoothly.
In the invention, the screw seat is higher than the surrounding surface, so that water may hardly invade into the screw fixing area.
Also in the invention, the height of the surface of the screw seat is set at a proper height so that the screw head may not project outside from the upper surface after tightening the screw.
The invention as set forth in claim 1 relates to an outdoor unit of separate type air conditioner having a top plate for covering constituent members disposed in the outdoor unit main body to protect from outside, in the upper part of the outdoor unit main body, in which an outside surface inclined to the installation surface of the outdoor unit is disposed on the top plate, and the top plate and the outdoor unit main body are fixed with a screw at the outside surface, and therefore, in this constitution, as the screw fixing part of the upper surface of the top plate is inclined when installing, staying of water in the screw fixing area can be prevented.
The invention as set forth in claim 2 relates to an outdoor unit of separate type air conditioner having a top plate for covering constituent members disposed in the outdoor unit main body to protect from outside, in the upper part of the outdoor unit main body, in which a screw seat having a higher seat surface than the surrounding surface is disposed in the upper surface of the top plate, and the top plate and the outdoor unit main body are fixed with screw at the screw seat, and therefore, in this constitution, since the screw seat having a higher seat surface than the surrounding surface is provided, invasion of water into the screw fixing area is prevented, and corrosion of screw can be prevented.
The invention as set forth in claim 3 relates to an outdoor unit of separate type air conditioner having a top plate
