AQUA-VENDING MACHINE WITH INTERNAL AQUA-TANK (VERSIONS) Russian patent published in 2020 - IPC G07F13/00 

FIELD: aqua-vending machines.

SUBSTANCE: invention relates to aqua-vending machines, i.e. to automatic water dispensers by means of automatically controlled water dispensing from water tank, located inside the device housing, into container of water purchaser. Technical problem lies in the need to widen the range of aqua-vending devices with an internal water tank by creating such a special design of the apparatus which is characterized by a compromise combination of a number of opposite requirements: maximizing reservoir water capacity, minimizing (in plane) dimensions of the device, high efficiency of automatic irrigation of aqua-tank before its filling with drinking water. Aqua-vending machine in its first version comprises housing 1 in the form of vertically oriented rectangular parallelepiped with front 2 and rear 3 walls, aqua-tank 4, which is made in form of a direct hyperelliptic cylinder and is located in housing 1, technical means associated with purchase and sale of water and water distribution from aqua-tank 4 into consumer container, located in housing 1. Aqua-tank 4 is made in form of vertical direct hyperelliptic cylinder, guide of which is hyperellipse with semi-axes a₁ and b₁. This hyperellipse is a Lamé curve characterized by the following ratios: (x/a₁)^m+(y/b₁)^m=1, 2, 8 ≤ m ≤ 10, a₁>b₁. Aqua-vending machine in its second version is characterized by its housing in form of vertically oriented direct hyperelliptic cylinder, guide of which is hyperellipse with semi-axes a₂ and b₂. This hyperellipse is a Lamé curve characterized by the following ratios: (x/a₁)ⁿ+(y/b₁)ⁿ=1, 2, 8 ≤ n ≤ 10.

EFFECT: technical result consists in implementation of said designation by making aqua-tank of such shape, which combines known advantages of both in shape and rectangular in plan shape, but does not have inherent forms of these separately known shortcomings when used in design of aqua-vending machines with internal aqua-tank.
