Abstract
The present invention relates to a device for supplying liquids comprising heating elements (3) heating up said liquids and an electric drive pumping group (101). The characteristic is that the pumping group (101) comprises an intake (102) and at least a first and second intake duct (8a-8b, 8c-8d, 8e-8f), and is further equipped with an impeller (11a, . . . , 11c), said first and second intake duct (8a-8b, 8c-8d, 8e-8f) being selectively activated according to the direction of rotation of said impeller (11a, . . . , 11c) of the pumping group (4a, . . . , 4c).
Claims15
A device for supplying liquids in vending machines for food or drinks, the device being valveless and comprising a heating arrangement (3) for heating up said liquids and an electric drive pumping group (4;
- 101), characterized in that each pump of said pumping group (4;
- 101) has an intake (4′;
- 102a, 102b), at least a first and a second vertical output duct (8a-8b, 8c-8d, 8e-8f, 800a, 800b) for conveying liquids contained in a tank (2) to corresponding mixing devices (7a, . . . , 7F each being equipped with at least an impeller (11a, . . . , 11c, 110a, 110b), housed in a shell (12, 103) having an open bottom and a curved side wall (12a), said first and second output ducts (8a-8b, 8c-8d, 8e-8f) each having an intake (Ia-Ib, Ic-Id, Ie-If) arranged on a vertical tangent of the curved side wall 12a) of said shell (12, 103), the output ducts being selectively activated according to the direction of rotation of said at least one impeller (11a, . . . , 11e) in said pumping group (4, 101) and the intakes (Ia-Ie) and vertical outlet ducts being valveless and unobstructed.
A device for supplying liquids to vending machines for heated food or drinks comprising:
- a tank for containing liquid;
- a heater in the tank;
- at least one pump in the tank;
- the pump having a housing arrangement with at least one impeller therein driven by a reversable motor that can Mate the impeller in opposite directions;
- first and second unobstructed, valveless intakes associated with the housing arrangement the first intake being tangentially positioned on the curved vertical wall of the housing at a first location and the second intake being tangentially position on the curved vertical wall of the housing at a second location angularly removed from the first location by an angle sufficient to prevent displacement of liquid loin the housing which the impeller is rotating clockwise and allowing displacement of liquid horn the container when the impeller is rotating counter clockwise;
- the first and second intakes being connected by first and second vertically extending valveless and unobstructed outlet ducts to mixing devices for mixing the liquid with first and second additives to make first and second heated drinks, and
- a motor controller for rotating the impeller in opposite directions to select first or second heated food or drinks.
