FIELD: physics.
SUBSTANCE: invention relates to imported aqua vending, i.e. to vending machines of imported drinking water by means of automatically controlled dispensing of this water into containers of water buyer. Technical problem lies in the need to simplify the design of the aqua reservoir and increase the reliability of the imported aqua vending by combining two functions in a single design of the aqua reservoir: standard function of drinking water accumulator directly intended for sale, and function of final stage of water purification by separation of settled water and accumulation of this water in the same tank. Water reservoir for imported aqua vending comprises tank 1 with bottom 2, water level sensor 3 in tank 1 and outlet pipe 4 with controlled outlet valve 5 for dispensing water into container of water buyer. At that, tank 1 is made either in form of straight cylinder with bottom 2 in form of corresponding cone, vertex 6 of which is directed downwards, and in this vertex 6 drain branch pipe 7 with controlled drain valve 8 is installed, or in the form of a straight prism with bottom 2 in the form of a corresponding pyramid, vertex 6 of which is directed downwards and in this vertex 6 there is drain pipe 7 with controlled drain valve 8. In addition, said outlet pipe 4 is installed on the side wall of tank 1 in the lower part of this side wall, and said sensor 3 is a primary converter of water pressure into an electrical signal, located outside the inner space of tank 1 and is hydraulically connected to the inner space of tank 1 at the level of the lower part of its side wall with the possibility of creating, by means of a controller, connected to sensor 3 and at least to outlet valve 5, conditional zero level 9 of water in tank 1, functionally dividing the volume of this water into two zones – upper zone 10 of water intended for imported aqua vending, and lower zone 11 of settled water.
EFFECT: providing functional division of all water into two zones: upper zone 10 of water intended for imported aqua vending, and lower settled water zone 11, which performs the function of a water purification device with the possibility of efficient draining of this settled water from this zone into the sewage system.
