A machine for producing and dispensing products such as ice cream, iced beverages or granita comprises a removable product-containing tank which is provided at its front end with a tap for dispensing the product and which, via its rear opening, sealingly houses a cooling element with a substantially horizontal axis and a motor-driven mixer element. The tank is removable from the machine by means of extraction from its operating position in a disassembly direction which is substantially parallel to the axis of the cooling element, and snap-engaging means for locking the movement of the tank are provided between the tank and its seat on the base of the machine, said means being able to be manually released by means of operation of at least one operating lever.

1. A machine for producing and dispensing a product including ice cream, iced beverages or granita, comprising a removable product-containing tank having a front end with a tap for dispensing the product and a rear opening, wherein the tank sealingly houses a cooling element with a substantially horizontal axis and a motor-driven mixer element which rotates coaxially with the cooling element so as to keep the product stirred and push the product towards the dispensing tap, the tank being removable from the machine by means of extraction from an operating position in a disassembly direction which is substantially parallel to the substantially horizontal axis of the cooling element, wherein the tank comprises a bottom surface which faces a corresponding seat on a base of the machine and further comprises snap-engaging means for locking movement of the tank in the disassembly direction, the snap-engaging means provided between said seat and the tank and being able to be manually released by means of operation of at least one operating lever, wherein the snap-engaging means comprises a snap-engaging device mounted on the bottom surface of the tank, or which is mounted for remaining on the base of the machine after removal of the tank, and a front edge directed towards the front end of the tank and engageable with a corresponding engaging surface in the seat, the operating lever allowing the snap-engaging device to be moved manually into a position where the front edge is disengaged from the corresponding engaging surface in the seat. 2. The machine according to claim 1, wherein the front edge of the snap-engaging device is resiliently pushed so as to engage with the corresponding engaging surface present in the seat in order to prevent forward movement of the tank in the disassembly direction, the operating lever configured to move the snap-engaging device into a position where the front edge is released from the corresponding engaging surface in the seat. 3. The machine according to claim 2, further comprising a constraining means provided between the tank and the seat and configured to prevent raising of the tank from the seat when the tank is in the operating position. 4. The machine according to claim 3, wherein the constraining means comprise a first engaging element present below the tank and a complementary second engaging element present in the seat, wherein the first and second elements slidably engage when the tank is in the operating position and have vertically facing surfaces which form the constraining means configured to prevent raising of the tank from the seat. 5. The machine according to claim 1, wherein the operating levers are two in number and are designed in the form of tabs projecting symmetrically on opposing sides of the tank in vicinity of the front end of the tank. 6. The machine according to claim 2, wherein the snap-engaging device comprises a rigid plate which defines the front edge and which at a rear is supportably hinged on the tank. 7. The machine according to claim 6, wherein a resilient element is present between the plate and the tank and resiliently pushes the plate with the front edge into an engaged position. 8. The machine according to claim 1, wherein the at least one operating lever is seated in an associated seat in the base and causes release of the snap-engaging means with upward movement of the at least one operating lever. 9. The machine according to claim 1, wherein the rear opening of the tank is sealingly closed around a base of the cooling element by means of a seal present in a vertical wall of the machine from which the cooling element and the mixer element project. 10. The machine according to claim 1, wherein the mixer element is designed in form of a cylindrical spiral screw which is rotatable about the cooling element and which engages, at a front end of the cooling element, on an end of a motor-driven shaft which passes axially through the cooling element.
