Built-in box for supplying internal units of air conditioning systems provided with a condensate collection tray

Abstract

A built-in box for supplying internal units of air conditioning systems includes an essentially parallelepiped-shaped containment body in which there is identified a space delimited by a bottom and by four walls, a tray associable to the bottom of the containment body, for collecting the condensate generated in the internal unit, the tray being laterally provided with at least one discharge duct for discharging the condensate. Inside the tray and in proximity of the discharge duct, there is housed a float which cooperates with the internal walls of the tray for closing the discharge duct at the inlet mouth thereof through a shutter, the float being constituted by a box-shaped element, a laminar wall, rotatably connected to the end part of the tray and stably connected to the box-shaped element, the laminar wall having a gasket suitable to rest against the end part of the tray and close the inlet mouth.

What is claimed is: 
     
         1 . A built-in box for supplying internal units of air conditioning systems comprising:
 an essentially parallelepiped-shaped containment body in which there is identified a space delimited by a bottom and by four walls;   a tray associable to the bottom of said containment body, for collecting the condensate generated in the internal unit, said tray being laterally provided with at least one discharge duct for discharging the condensate wherein, inside said tray and in proximity of at least one discharge duct, there is housed a float which cooperates with the internal walls of said tray for closing said at least one discharge duct at the inlet mouth thereof through shutter means, said float being constituted by a box-shaped element, a laminar wall, rotatably connected to the end part of the tray and stably connected to said box-shaped element, said laminar wall having a gasket suitable to rest against the end part of the tray and close the inlet mouth of the discharge duct.   
     
     
         2 . The built-in box according to  claim 1 , wherein the laminar wall has, at the top part, a tubular rod having ends projecting with respect to said laminar wall, the axis (X) of said tubular rod being rotational axis of said float. 
     
     
         3 . The built-in box according to  claim 1 , wherein the box-shaped element and said laminar wall are connected to each other through a vertical strip essentially perpendicular to a surface of said box-shaped element and said laminar wall. 
     
     
         4 . The built-in box according to  claim 1 , wherein the box-shaped element, said vertical strip and said laminar wall are made in a single piece made of plastic material. 
     
     
         5 . The built-in box according to  claim 1 , wherein the box-shaped element is open towards the top and it has a bottom which receives a hydraulic thrust in presence of water condensate such to rotate said float around the axis (X) of the tubular rod so as to move said gasket away from the wall of said tray. 
     
     
         6 . The built-in box according to  claim 1 , wherein the containment body has predefined fracture areas in the upper wall, in the lateral walls and in the rear wall, so as to enable, when open, the entry and exit of pipes for cooling the air conditioning system. 
     
     
         7 . The built-in box according to  claim 1 , wherein it further has a shaped plate placed above the upper perimeter edge of said tray, such to separate the space in which said float acts, from the containment body of the built-in box, said shaped plate having a flat surface and a plurality of flat fins arranged inside said tray, said fins being substantially perpendicular to said flat surface. 
     
     
         8 . The built-in box according to  claim 1 , wherein it has a pair of front fins arranged at the lateral walls of said containment body, said front fins having slots suitable to house means for fixing to the wall that support said built-in box. 
     
     
         9 . The built-in box according to  claim 8 , the front fins have, at the coupling with the containment body, pre-fracture lines such to enable detachment from said containment body if necessary. 
     
     
         10 . The built-in box according to  claim 1 , further comprising, at the rear wall of said containment body, a bubble level gauge suitable to indicate the horizontal position of said built-in box.
