FIELD: aqua-vending machines.
SUBSTANCE: invention relates to aqua-vending machines - i. e. to vending machines for drinking water. The technical problem lies in the need to significantly improve the quality of the final drinking water due to its more effective disinfection, i.e. of the water that is already in the container of the buyer of water as a result of the sale and purchase of this water, without resorting to secondary ultraviolet treatment (i.e., treatment of the container), which is fraught with the infliction of certain harm to the health of the buyer by this secondary ultraviolet. The device contains a water flow expander (1) with inlet (2) and outlet (3) nozzles, a source of ultraviolet radiation (4), an ozone generator (5), a chamber (6) for pouring water into a container (13) of a water buyer equipped with a feed nozzle (7) of a water pouring chamber having an outlet (8) and two inlets (9 and 10) as well as valves (11, 12). The source (4) is installed in the expander (1). The outlet of the expander (1) is hydraulically connected to the chamber (6) through the valve (12) and the supply pipe (7) at the inlet (10) of this pipe. The ozone generator (5) is installed with the possibility of ozonizing the inner space of the container (13) of the water buyer during the period when this container is in the water filling chamber (6).
EFFECT: technical result consists, firstly, in increasing the efficiency of ultraviolet disinfection of water due to a significant decrease in the speed of water movement during its passage in the zone of ultraviolet radiation, as well as due to the creation of turbulence in this zone using the effect of a sudden narrowing of the water flow, and, second, in maintaining the quality of water in the container of the buyer of water, specified by the specified ultraviolet disinfection, by ozonizing the inner space of this container before dispensing the water, pre-treated with ultraviolet light, into the container of the buyer of water.
