<p>A machine (1) for producing ice-cream and the like comprising an outer boxlike housing (2) and, within the boxlike housing (2), a processing tank (3) that extends into the boxlike housing (2), from the upper wall (2a) of the latter, and a discharge manifold (9) which branches from the bottom of the processing tank (3) to reach the boxlike housing (2) at a front wall (2b) of the latter, and is structured so as to allow a product contained in the processing tank (3) to flow out of the machine (1); the discharge manifold (9) comprising a tubular duct (10) which protrudes from the bottom of the processing tank (3) and ends with a mouth assembly (11) which through-engages an appropriate opening (11a) obtained on the front wall (2b) of the boxlike housing (2); the mouth assembly (11) comprises a central sleeve (11a) that is rigidly and fixedly attached to the tubular duct (10), and protrudes from the end of the tubular duct (10) towards the outside of the boxlike housing (2), through-engaging said opening (11a) on the front wall (2b) of the boxlike housing (2); an outer coupling flange (12) which is rigidly and fixedly attached outside the tubular duct (10), upstream of the central sleeve (10a), and is adapted to be arranged in abutment on the inner surface of the front wall (2b) of the boxlike housing (2) along the peripheral edge of said opening (11a); an inner protective grid (13) which is positioned on the central sleeve (10a) of the mouth assembly (11) so as to prevent foreign bodies from rising along the tubular duct (10) at the back, and is rigidly and fixedly attached to the body of said central sleeve (10a); an outer locking plate (14), which is centrally provided with a through-hole (14a) having a complementary shape to that of the central sleeve (10a) of the mouth assembly (11), and is directly fitted on the central sleeve (10a) of the mouth assembly (11), with the rear face in abutment on the outer surface of the front wall (2b) of the boxlike housing (2); and finally anchoring means (15) structured so as to hold the flange (12) of the mouth assembly (11) and the locking plate (14) one against the other, firmly locking the end of the tubular duct (10) on the front wall (2b) of the boxlike housing (2).</p> |
