FIELD: aquavending machines.
SUBSTANCE: invention relates to aquavending machines, i.e. drinking water vending machines that automatically control filling of water into a customer's container by means of a bottling unit. The challenge is the need for a water ultraviolet disinfection performed just before the water enters the bottling spout and to ensure that the bottling spout interior is promptly protected against accidental or deliberate contamination through the spout outlet end. Unit contains a vertically oriented water filling nozzle 1, a UV lamp 2 installed in a protective tube 3 made of UV-permeable material, and a flow-through aqua-tank 4. The latter has an inlet nozzle 5 for hydraulic connection to the water source and an outlet nozzle 6, by means of which the tank 4 is hydraulically connected to the nozzle 1, in particular to the nozzle upper inlet end 7. In this case, the protective tube 3 with the lamp 2 is arranged inside the aqua-tank 4 to form a flowing container 8 between the aqua-tank 4 body and the protective tube 3, so that the conventional line of sight 9 coinciding with the axis of the nozzle 1 crosses the lamp 2. This intersection means that ultraviolet rays produced by the part of the lamp 2, which is on the intersection with the line 9, are freely spread along the line 9, i.e. freely go through the nozzle 6 into the internal cavity of the nozzle 1 performing the cavity disinfecting treatment.
EFFECT: invention simultaneously provides two processes: the process of water disinfection by means of an ultraviolet lamp before the water is supplied to the water filling spout inlet and the process of the water filling spout internal space irradiation by means of the ultraviolet lamp.
