Patent ID: 8322274

Claim:
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 within the boxlike housing ( 2 ) from the upper wall ( 2 a ) thereof; and a discharge manifold ( 9 ) that branches from the bottom of the processing tank ( 3 ) up to the boxlike housing ( 2 ) at the front wall ( 2 b ) thereof, and is structured so as to allow the outflow of the product contained in the processing tank ( 3 ) outside the machine ( 1 ); the discharge manifold ( 9 ) comprising a tubular duct ( 10 ) protruding from the bottom of the processing tank ( 3 ) and ending in a mouth assembly ( 11 ) that through-engages an appropriate opening ( 11 a ) realized on the front wall ( 2 b ) of the boxlike housing ( 2 ); the machine ( 1 ) for producing ice-cream and the like being characterized in that said mouth assembly ( 11 ) comprises a central sleeve ( 11 a ) 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 ( 11 a ) on the front wall ( 2 b ) of the boxlike housing ( 2 ); an outer coupling flange ( 12 ) which is rigidly and fixedly attached to the outside tubular duct ( 10 ), upstream of the central sleeve ( 10 a ), and is adapted to be arranged in abutment on the inner surface of the front wall ( 2 b ) of the boxlike housing ( 2 ) along the peripheral edge of said opening ( 11 a ); an inner protective grid ( 13 ) which is positioned on the central sleeve ( 10 a ) 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 permanently attached to the body of said central sleeve ( 10 a ); an outer locking plate ( 14 ), which is centrally provided with a through-hole ( 14 a ) having a complementary shape to that of the central sleeve ( 10 a ) of the mouth assembly ( 11 ), and is fitted directly on the central sleeve ( 10 a ) of the mouth assembly ( 11 ), with the rear face in abutment on the outer surface of the front wall ( 2 b ) of the boxlike housing ( 2 ); and anchoring means ( 15 ) structured so 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 ( 2 b ) of the boxlike housing ( 2 ).
