Abstract

Hot air generator, being of the type of those that incorporate a combustión chamber, housed in a housing in which an air circulation is established that absorbs the heat radiated through the walls of the combustión chamber, essentially characterized in that on top of said combustión chamber and inserted between the smoke outlet of said chamber and the evacuation chimney thereof, a labyrinthic passage is established based on a plurality of discoidal receptacles, arranged coaxially, properly spaced and with its imaginary axis in a horizontal arrangement, interconnected eccentrically with each other through short alternating pipes that are alternately out of phase in opposition, each of said receptacles being provided with two plates, of a frusto-conical configuration, whose mouths, corresponding to their imaginary larger bases, they have different perimetral tabs it is through these that the fixation of the same is done with the collaboration of a u-section band, which is adapted perimetrally to said pair of tabs and which closes on itself, preferably with a welding point, with the particularity besides that the intercommunication conduits between receptacles materialize in an orifice established in the smaller and closed base of each plate that finishes with a decisive stuffing of a short cylindrical neck, the unión between receptacles being carried out by means of a perimeter welding line that affects the mouths of each pair of complementary collars, all in a way that a heat recovery is obtained based on a plurality of identical dishes that are mounted, inside each receptacle, with their necks out of phase in diametrical opposition.
