The machine includes a first hydraulic circuit (2) with a tank for a liquid to be dispensed and a device for heating the liquid. The first hydraulic circuit (2) includes a removable tank (5) for containing the liquid to be dispensed and at least one delivery pipe (12), the first hydraulic circuit (2) being operative by command between an open configuration, in which the liquid is dispensed outside of the machine, and a closed position, in which liquid is circulated inside the machine. The device for heating the liquid includes a closed second hydraulic circuit (3) for a heating liquid and a heat exchanger (4) internally of which at least one tract of the delivery pipe (12) and at least one tract of the closed second hydraulic system (3) pass.

A drinks dispensing machine comprising a first hydraulic circuit (2) with a tank for a liquid to be dispensed and means for heating the liquid, wherein:the first hydraulic circuit (2) comprises a removable tank (5) for containing the liquid to be dispensed and at least one delivery pipe (12), the first hydraulic circuit (2) being operative by command between an open configuration, in which the liquid is dispensed outside of the machine, and a closed position, in which liquid is circulated inside the machine; the means for heating the liquid comprise a closed second hydraulic circuit (3) for a heating liquid and a heat exchanger (4) internally of which at least one tract of the delivery pipe (12) and at least one tract of the closed second hydraulic system (3) pass. 2. The machine of claim 1, wherein the heat exchanger (4) comprises a tank (6) for the heating liquid which constitutes the at least one tract of the closed second hydraulic circuit (3), means (7) for heating the heating liquid, a spiral tract (8) which is part of the at least one tract of delivery pipe (12), at least one safety valve (9) and means (10) for measuring a temperature of the heating liquid.3. The machine of claim 2, wherein the first hydraulic circuit (2) comprises a first pump (11) which is operative on command on the delivery pipe (12), which delivery pipe (12) is connected at an end thereof to the removable tank (5) and which delivery pipe (12) terminates at another end thereof in a dispenser (13), a return pipe (14) having at an end thereof a first connector (15) and at another end thereof a second connector (16), the return pipe (14) being connectable to the dispenser (13) by means of the first connector (15) and being connectable to the tank (5) by means of the second connector (16), thus completing the first hydraulic circuit (2).4. The machine of claim 3, wherein the second hydraulic circuit (3) comprises a second pump (17), which is connected at an outlet thereof to a delivery pipe (18) leading to the tank (6) and connected at an inlet thereof to a return pipe (19) coming from the tank (6).5. The machine of claim 4, wherein the means (7) for heating the heating liquid comprise an electrical resistance (20) inserted in the tank coaxially to the spiral tract (8) and a binding electrical resistance (21) wound externally about the tank (6) and externally lagged by an insulating layer (22).6. The machine of claim 5, wherein the means (10) for measuring the temperature of the heating liquid comprise at least one thermostat (23) for controlling the pump (17) and controlling supply to the electrical resistances (20, 21), and a bimetallic thermostat (24) with manual reset.7. The machine of claim 5, wherein the means (10) for measuring the temperature of the heating liquid comprise an electronic card (25) for controlling the pump (17) and controlling supply to the electrical resistances (20, 21) comprising sensors for detecting a temperature of the heating liquid.8. The machine of claim 6, wherein the removable tank (5) comprises a microswitch (26) arranged externally of a bottom thereof and activated by a weight of the removable tank (5) for signalling an emptying of the removable tank (5).9. The machine of claim 7, wherein the removable tank (5) comprises a microawitch (26) arranged externally of a bottom thereof and activated by a weight of the removable tank (5) for signalling an emptying of the removable tank (5).
