No. 3, patent holder V. V. Bakaleiko; description of the utility model according to patent RU No. 173506 U1, IPC G07F 13/00, published on August 29, 2017, Bull. No. 25, patent holder M. V. Reshetnikov).

Brief description of the drawings

In FIG. 1 shows a schematic representation of the longitudinal (vertical) section of the aqua vending machine, which shows only the body of the aqua vending machine, aqua reservoir and fan; in fig. 2 is a view A-A in FIG. 1. Implementation of the utility model

The aqua vending apparatus contains a thermally insulated body 1 of the aqua vending apparatus, which is a hollow rectangular parallelepiped with four side walls 2 and a bottom 3. At the same time, one side wall (side face) of the housing 1 is made in the form of a door that functions as the front panel of the aqua vending apparatus (the door in the figures is not highlighted).

The aqua vending apparatus also contains an aqua reservoir 4 made of metal without thermal insulation for drinking water with four side walls 5 and a bottom 6 located in a certain horizontal plane 7.

In addition, the device contains located in the upper part of the housing 1 (i.e. above the aqua reservoir 4) means for preparing drinking water from tap water and dispensing drinking water into the container of the buyer of drinking water from the aqua reservoir 4 (not shown).

At the same time, the aqua reservoir 4 is located below the indicated means for preparing drinking water from tap water and dispensing drinking water into the container of the buyer of drinking water from the aqua reservoir (mainly in the lower part of the housing 1) at a distance from the bottom 3 of the housing 1, so that between the bottom 3 and the plane 7 of the location the bottom 6 of the tank 4 is formed by the functional space 8, in which the fan 9 is located.

In addition, the aquareservoir 4 is made and located so that its side walls 5 are associated with the side walls 2 of the body 1 that enclose them, so that side gaps S are formed between the enclosing walls 2 and the male walls 5 for the passage of air blown by the fan 9.

In addition, in the tank 4 there is a source of ultraviolet radiation (not shown), intended primarily for the disinfection of the drinking water in the tank 4. However, since in this source only a small part of the electrical energy provides the desired ultraviolet radiation, its other (electrical) part is converted into thermal energy, which additionally heats the drinking water in the tank 4.

The concept of “clearance” is widely known in mechanical engineering: “A clearance in mechanical engineering is the distance between two surfaces of mating machine parts and other structures; is defined as the difference between the inner size of the female part and the outer size of the male part ”(see: Polytechnic Dictionary / Editorial: A.Yu. Ishlinsky (editor-in-chief) and others - 3rd ed., revised and additional - M .: Great Russian Encyclopedia, 2000. - S. 173).

In the context of the above definition in the claimed technical solution, the covered part is the aqua reservoir 4, taken in part of its side walls 5, and the female part is the body 1, taken in part of its side walls 2. The so-defined “gap” exhaustively indicates the possibility of air passing through it , blown by the fan 9 from the functional space 8 into the gaps 3 at a given speed, namely, one that provides optimal heat exchange of this air with the water in the tank 4 through the side walls 5 and the bottom 6 of the tank 4.

The operation of the device is as follows.

Water from the water supply passes through the means of purification, disinfection and conditioning of water (filters, membrane, etc.) and, becoming potable, enters the aqua reservoir 4, equipped with an ultraviolet emitter for continuous disinfection of drinking water (not shown) located in the aqua reservoir 4. Upon request of the buyer, drinking water is dispensed into the buyer's container from the tank 4, which, at the command of the controller, is immediately replenished with new drinking water obtained from tap water by cleaning it. Thus, in the tank 4 there is always drinking water, which is renewed as it is sold and, as a result, always has a positive temperature, additionally maintained by the source of ultraviolet radiation located in the tank 4. In this case, the fan 9 is turned on when two conditions are met: the presence of water in the tank 4 and a negative ambient temperature.

The fan 9 provides air supply from the functional space 8 to the gap 8 on one side of the tank 4. This air passes through this gap and is heated by the water in the tank 4 through the bottom 6 and the corresponding wall 5 of the tank 4 and rises to the upper part of the body 1 There (above) the air temperature decreases and it, through the gap (or gaps) on the other side of the tank 4, descends into the lower part of the body 1, passing through the gap, heats up from the water in the tank 4, through the corresponding wall 5 of the tank 4 and enters functional space 8 to the inlet of the fan 9, thereby closing the cycle of circular air movement inside the housing 1.

Such a maintenance of a positive air temperature only due to the thermal energy of the water in the tank 4, supplemented by heat from a source of ultraviolet radiation, is possible at relatively low negative ambient temperatures (for example, down to -10°C). At a significantly lower ambient temperature (for example, -30°С), the indicated thermal energy will not be enough and then the controller, in addition to the main air heating system from the water of the aquatic tank 4, connects an additional air heating system using an electric heater installed in the functional space 8 on the flow line air from fan 9. Under such circumstances, when excessively low negative temperatures are possible in the region of operation of the aqua vending machine, instead of fan 9, a fan heater should be installed immediately.

Thus, the use of the thermal energy of the water that is always in the tank 4 (energy supplemented by the heat energy from the source of ultraviolet radiation located in the water of the tank 4) to heat the air inside the body 1, in some cases eliminates the need for an electric heater, in other cases reduces the operating time of the electric heater, which in any case allows you to significantly save electricity during the operation of the aqua vending machine in winter.
