ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a flush-mount enclosure, particularly for making provisions for air-conditioning systems.
Currently, the provision of an air-conditioning system entails the need for a connection between an external motorized condensing unit and an internal unit by means of two thermally insulated tubes which are adapted to transfer the refrigeration fluid between the two units.
The internal unit must further be supplied with power, usually by means of an electrical cable, and has a pipe for discharging the condensed moisture.
In order to facilitate the installer in positioning the internal unit, it is known to provide enclosures for the refrigeration tubing and for the electrical cable; such enclosures are essentially shaped like parallelepipeds and are recessed in the wall at the region where the internal unit is placed.
Such enclosures have standardized dimensions in order to allow to place thereat suitable templates for mounting the internal unit.
One problem that arises is the discharge of condensation: usually, in the case of provisions for the air-conditioning system, it is known to build into the wall a pipe for discharging the condensed water; the condensation outlet of the internal unit must subsequently be connected to such pipe.
In the internal unit, the condensation outlet may be located on a side that does not correspond to the one where the discharge pipe has been provided in the wall, thus forcing the installer to provide the connection by means of a hose, whose path is necessarily approximately horizontal, in order to reach the other end; therefore condensation may stagnate and bad odors may form.
SUMMARY OF THE INVENTION
The aim of the present invention is to solve the above-mentioned problems, eliminating the drawbacks of the cited prior art, by providing a flush-mount enclosure, particularly for making provisions for air-conditioning systems, which allows optimum placement not only of, for example, the refrigeration tubing and of the power supply cable for an internal unit, but also of the discharge or condensation pipe of the internal unit, at the same time allowing optimum drainage of the condensation.
Within the scope of this aim, an important object of the present invention is to provide an enclosure in which optimum condensation draining can be achieved regardless of whether the condensation outlet connected to the internal unit is located at the right end or at the left end of the internal unit.
Another important object of the present invention is to provide an enclosure which avoids the formation of stagnating condensed water.
Another object of the present invention is to provide an enclosure which is structurally simple and has an optimum connection to a condensation outlet without requiring subsequent interventions of the installer when the internal unit is fitted.
This aim, these objects and others which will become apparent hereinafter are achieved by a flush-mount enclosure, particularly for making provisions for air-conditioning systems, which comprises a box-like containment body for refrigeration tubing and a power supply cable, characterized in that a condensation collector is associable, so that it can be removed and turned through 180°, with said box-like body in a downward region, said collector having at least an outlet arranged at a lateral end thereof.
