APPARATUS TO PRODUCE ICE-CREAM

摘要

Apparatus for making ice cream or similar cold products, comprising a cooling chamber substantially cylindrical in shape (12), a cooling device (23) arranged around said cooling chamber (12) and a removable receptacle for the ice cream (13) , which may be associated with the cooling chamber (12), comprising the receptacle for the ice cream (13) a bottom (213) and a vertical wall (113), being in the receptacle (13) a rotary beater ( 14) associated with a driven shaft (19) substantially coaxial to the receptacle (13), with the particularity that said cooling device (23) comprises two opposite vertical fins (31) defining a vertical opening (20) allowing said cooling device (23) is at least partly elastic and can occupy said cooling device (23), selectively a first expanded position in which the receptacle for ice cream (13) s and can be inserted inthe inside said cooling chamber (12) or out of it, or a second closed position, in which said receptacle for ice cream (13) remains inside said cooling chamber (12) means of said cooling device (23), being arranged elastic means (30) to normally keep said cooling device (23) in said second closed position also being provided an opening device (32) for cooperating with the vertical fins (31) and selectively actuating said cooling device (23), one of these positions to the other, said opening device (32) at least one element disposed cam (36) between the two vertical fins (31) comprising and a central vertical axis (34), characterized in that said cam element (36) is configured to have a defined by two lateral parallel planes (36a) and two curved lateral perimeter s (36b), the two curved sides (36b) convex outwards and connected on opposite sides of said side parallel planes (36a), the distance (d1) between said parallel side planes (36a) equal to distance between the two vertical fins (31) when the cooling device (23) is in said second closed position, maintaining said vertical fins (31) and around the cooling device (23) in the closed position very stable, due to the action of said elastic means (30), the distance (d2) between said greater than the distance (dl) between the side said parallel planes (36a), with the particularity that said curved lateral curved side (36b) (36b ) can separate said vertical fins (31) against the action of said elastic means (30), when rotating the cam (36) 90 ° about the central vertical axis (34) to bring said device ref rigerante (23) in said first posiciónensanchada.
