Brief description of the drawings

The attached figure shows a schematic representation of the longitudinal section of the aqua vending machine with a vertical plane perpendicular to the front panel of the aqua vending machine.

Implementation of the utility model

The aqua vending apparatus contains a thermally insulated body 1, which is a hollow rectangular parallelepiped with a bottom 2, a cover 3 and at least four side walls - the front side wall 4, which is the door and in the closed state the front panel of the aqua vending apparatus, the rear side wall 5, as well as other side walls housing 1 (not shown in Fig.).

The aqua vending apparatus also contains a water tank 6 made of metal without thermal insulation for drinking water with a bottom 7, a lid 8 and at least four side walls - front side 9, back side 10, as well as other side walls of the tank 6 (others are not shown in Fig. ). At the same time, a source of ultraviolet radiation (not shown) is located in the aqua-reservoir 6, intended for disinfection and heating of drinking water located in the aqua-reservoir 6. As for the fan 11, it is located in any of the following gaps between the body 1 and the tank 6. In addition, in the preferred embodiment of the tank 6, it has a shape similar to the shape of the body 1, which simplifies the formation of the necessary gaps between the body 1 and the tank 6 designed for aerodynamically efficient blowing outside the tank 6 by fan 11.

Aquareservoir 6 is made and located in body 1 so that the following gaps are formed between body 1 and aquareservoir 6:

- lower gap 12 between the bottom 7 of the aquatic tank 6 and the bottom 2 of the body 1 of the aqua vending machine;

- the upper gap 13 between the cover 8 of the aqua reservoir 6 and the cover 3 of the body 1 of the aqua vending machine;

- front side gap 14 between the front side wall 9 of the aqua reservoir 6 and the front panel 4 of the aqua vending machine;

- rear side gap 15 between the rear side wall 10 of the aqua reservoir 6 and the rear side wall 5 of the aqua vending machine;

- possible other side clearances.

The front side gap 14 in size (i.e., in terms of its cross-sectional area) exceeds the value (i.e., the cross-sectional area) of any other gap due to the fact that in the front gap 14 there are means of preparing drinking water hydraulically connected to the tank 6 from tap water (tap water filters, a reverse osmosis membrane for separating filtered water into permeate and concentrate, permeate modification means) and means for dispensing drinking water into the container 18 of the buyer of drinking water from this aqua reservoir, which requires sufficient volume for their placement. Front gap 14 also houses electronic aqua vending controls (not shown). Thus, the size of the gap 14 is actually determined by the filling chamber 16, which is part of the means for dispensing drinking water into the container 18 of the buyer of drinking water from the aquatic tank 6, which is intended for temporary placement of the container 18 of the buyer of drinking water in it and which contains a filling pipe in its upper the parts and the door 17 are made of a light-transmitting plastic material, such as a monolithic UV-protected polycarbonate.

The operation of the aqua vending apparatus is as follows.

Water from the water supply system passes through the means of purification, separation and modification (filters, membrane, etc.) and, becoming drinking water, enters the aqua reservoir 6, equipped with an ultraviolet emitter for continuous disinfection of drinking water in the aqua reservoir 6. At the request of the buyer, drinking water is dispensed into the container 18 of the buyer of drinking water from the tank 6, which, at the command of the controller, is immediately replenished with new drinking water obtained from tap water by filtering, separating and modifying it. Thus, in the tank 6 there is always drinking water, which is updated 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 6. In this case, the fan 11 is turned on when two conditions are met: the presence of water in the tank 6 and a negative ambient temperature. The fan 11 provides a circular circulation of air through the gaps 12, 15, 13 and 14 between the body 1 and the aqua reservoir 6, thereby blowing the aqua reservoir 6 from the outside, thereby heating up from the water of the aqua reservoir 6 and thereby maintaining a positive temperature in the gap 14, where the facilities are located. preparation of drinking water from tap water (filtration, separation, modification) and the issuance of drinking water to the container of the buyer of drinking water from the aqua reservoir 6, requiring a positive temperature for their normal operation. At the same time, the thermal energy of the water of the aqua reservoir 6 is supplemented by thermal energy from the source of ultraviolet radiation located in the water of the aqua reservoir 6, so that at relatively low negative temperatures of the air surrounding the aqua vending apparatus (for example, up to -10 ° C), this is enough to maintain a positive temperature in the gap 14. At a significantly lower temperature of the air surrounding the aqua vending machine (for example, -30°С), the indicated thermal energy of water will probably not be enough to maintain a positive temperature in the gap 14, and then the controller, to help the main air heating system from the water of the aqua reservoir 6, connects an additional air heating system using an electric heater installed in any gap. Under such circumstances, when extremely low negative temperatures are likely to occur in the region of operation of the aqua vending machine, a fan heater should be immediately installed instead of fan 11.

Thus, the use of the thermal energy of the water that is always in the aqua reservoir 6 (energy supplemented with thermal energy from the source of ultraviolet radiation located in the water of the aqua reservoir 6) to heat the air in the front gap 14, where the means of preparing drinking water from tap water and dispensing drinking water into the container of the buyer of drinking water from the tank 6, in some cases (not too cold) it completely eliminates the need to use an electric heater, in other cases (excessively cold) it involves the use of an electric heater, but much less time, so in any case, the use of thermal energy of drinking water, which is always in the aqua-reservoir 6, allows you to significantly save electricity during winter aqua vending.
