Abstract

FIELD: aquavending with disinfecting ozonation.SUBSTANCE: inventions relate to aquavending with disinfecting ozonation. The technical problem lies in the need to create such technical means of aquavending, which ensure effective disinfection of the buyer's water container. Aquavending with disinfecting ozonation consists in the fact that water is sold using a vending machine containing a water filling chamber 4, by releasing water into the buyer's water container 12, which the buyer pre-installs in the chamber 4. Then, when the water is not released into the container 4 yet, ozone generation is performed for a given time using an ozone generator 2 and the generated ozone is supplied to the container 12. After that, the mentioned release of water from the source 1 to the container 12 is performed. The water pump contains a water source 1, an ozone generator 2 and a water filling chamber 4. In the upper part 5 of the chamber 4, a supply pipe 6 is installed, designed to supply ozone and water to the chamber 4. The supply pipe 6 is made with two inputs 8 and 9 and one output 7. In this case, the input 8 is hydraulically connected to the water source 1, and the input 9 through the valve 3 is connected to the output of the ozone generator 2.EFFECT: ensuring disinfection of the internal space of the water buyer's container every time before releasing water into this container.1 cl, 1 dwg

The technical field to which the invention relates

The invention relates to aqua vending with disinfecting ozonation, i. E. to devices for the sale of drinking water using vending machines, in which the disinfecting properties of ozone are used to improve the quality of water, by means of a controlled supply of quality water paid by the buyer from a common reservoir to the container (capacity) of the buyer of water.

State of the art

Known aqua vending machine with disinfecting ozonation, containing a common reservoir with water, an ozone generator and a chamber for pouring water into the container of the buyer of water. In this case, the specified reservoir simultaneously performs the function of a bubbler, i.e. contains in its lower part tubes with openings for supplying thin jets of ozone to the water, as a result of which the specified bubbling is carried out in order to disinfect the water in the tank (see the description of the utility model, for example, according to patent RU No. 113043 U1, IPC G07F13 / 00, published on 27.01.2012 Bulletin No. 3, according to RU patent No. 138563 U1, IPC G07F15 / 00, published on 03/20/2014, Bulletin No. 8 or according to RU patent No. 173506 U1 IPC G07F13 / 00, published on 08/29/2017 Bul. No. 25).

The features of the known water pump, common with the features of the claimed water pump, are that it contains a common tank, an ozone generator and a water filling chamber, in the upper part of which a supply pipe is installed, designed to supply water to the container of the water buyer, while the inlet of this pipe is hydraulically associated with the specified reservoir (water source).

The reason that prevents from obtaining a technical result in the known water pump, which is provided by the declared water pump, is the lack of disinfection of the container of the buyer of water.

Known aqua vending machine with disinfecting ozonation (prototype), containing a water source, an ozone generator and a water filling chamber, in the upper part of which a supply pipe is installed, hydraulically connected to the water source through a water supply pipeline, while the ozone generator output is connected through a controlled shut-off valve with the specified pipeline (see the description of the utility model under the patent RU No. 139049 U1, IPC G07F7 / 00, published on 10.04.2014 Bull. No. 10).

The features of the known water pump (prototype), common with the features of the declared water pump, are that it contains a water source, an ozone generator and a water filling chamber, in the upper part of which a supply pipe is installed, designed to supply water to the container of the water buyer, while the input this branch pipe is hydraulically connected to the water source.

The reason that prevents from obtaining in the known water pump (prototype) the technical result, which is provided by the declared water pump, is the lack of disinfection of the container of the buyer of water (and also in the absence of disinfection of the filling chamber).

The technical problem to be solved by the claimed water heater is the need to create such technical means of aqua vending that ensure effective disinfection (sterilization of the inner surface) of the container of the water buyer. The relevance of such disinfection is that the buyer of water gets the opportunity to repeatedly (almost unlimitedly) use the same plastic container without reducing the quality of the water, which in turn reduces the pollution of nature with plastic waste, since it is not customary to throw away such container (subject to repeated sterilization) ...

Disclosure of the essence of the invention

The technical result, which mediates the solution of this technical problem, is to ensure the disinfection of the inner space of the container of the water buyer each time before the water is dispensed into this container by generating ozone and supplying this ozone to this container so that water falling into the ozone generator is excluded. disrupt its work. Additionally, the technical result consists in disinfection of the filling chamber every time after the water is dispensed into the container of the water buyer without the introduction of additional structural elements.

The technical result is achieved in the water-pump declared for patenting in that it contains a water source (1), an ozone generator (2) and a water filling chamber (4), in the upper part (5) of which a supply pipe (6) is installed, having an outlet (7 ), located below the upper part (5) of the chamber (4) and intended for supplying water to the container (12) of the purchaser of water, and two inlets (8) and (9), so that the inlet (8) of this branch pipe is hydraulically connected to the water source (1); in this case, the branch pipe (6) is either a tee having one common tube for the outlet of water and ozone, so that its other inlet (9) through the valve (3) is connected to the outlet of the ozone generator (2), or the branch pipe (6) is designed so that the outlet (7) is two tubes - one for water, the other for ozone, so that the outlet tubes (7) are located either parallel to each other or axially.

Brief Description of Drawings

The attached figure shows a diagram of the claimed water-supply unit for aquavending with disinfecting ozonation.

Implementation of the invention

A water supply for aqua vending with disinfecting ozonation contains a water source 1, an ozone generator 2, a valve 3 to prevent water from entering the ozone generator 2, a loading chamber 4 with an upper part 5, a supply pipe 6 having an outlet 7 and two inlets 8 and 9, a pipeline 10 water supply to chamber 4 (and container 12 of the purchaser of water) through pipe 6, pipeline 11 for supplying ozone to chamber 4 (and container 12) through valve 3 and pipe 6.

Water source 1 can have different designs. This can be a tank with imported drinking water or a tank filled with water taken from a water supply system, which has been appropriately cleaned and treated. This can be the outlet of the filter unit, to the inlet of which water from the water supply is directly supplied.

The ozone generator 2 can also have different designs. But it usually contains a spark gap that directly generates ozone, a high voltage current source for powering the spark gap, and a fan or air compressor (not shown).

The water filling chamber 4 is a container with a supply pipe 6 installed in its upper part 5, intended for separate (in time) supply of ozone to the container 12 of the purchaser of water and, if necessary, the subsequent supply of ozone to the chamber 4 when there is no container 12 in it. In this case, the branch pipe 6 has an outlet 7 located below the upper part 5 of the chamber 4, and two inlets 8 and 9 located above the upper part 5 of the chamber 4. The branch pipe 6 in the preferred embodiment of the water pump is a classic tee having one common pipe for water outlet and ozone. However, it can be designed so that the outlet 7 is two tubes - one for water, the other for ozone (not shown). In this case, the outlet tubes 7 can have a different arrangement relative to each other: 1) they can be located parallel to each other with or without their direct abutment to each other by their outer generators, 2) they can be located axially (a tube in a tube).

The valve 3 is designed so that it prevents water from entering the pipeline 11 and, accordingly, the ozone generator 2. It can be designed as a check valve or as an electrically controlled valve controlled by a controller (not shown).

The work of the water pump is as follows.

The purchaser of water makes the appropriate payment, installs his container 12 in the chamber 4 and starts the process of dispensing water using a user interface (not shown). After that, in automatic mode, the controller (not shown) opens valve 3 (if it is an electrically controlled valve) and turns on the ozone generator 2 for a specified time (for example, 10 seconds). Ozone flows through the pipeline 11 through the open valve 3 to the inlet 9 of the branch pipe 6 and then to the outlet 7 of this branch pipe and to the container 12 located with its neck directly under the outlet 7 of the branch pipe 6. As a result, during a given time (10 seconds) ozone, arriving in container 12 in this way, disinfects the inner cavity of this container. After a specified time (10 seconds), the controller turns off the ozone generator 2, closes valve 3 (if it is an electrically controlled valve) and then turns on the water supply from source 1 through pipeline 10 to inlet 8 of branch pipe 6 and then to outlet 7 of this branch pipe and into the container 12, located with its neck directly under the outlet 7 of the branch pipe 6. At the same time, due to the fact that the valve 3 is closed in the process of supplying water to the container 12, water does not enter the pipeline 11 and, accordingly, into the ozone generator 2, which could fail when water gets into it. After filling container 12 with water, the controller stops supplying water, while the buyer of water in one form or another is invited to take his container 12 from chamber 4. At this, the current working cycle of aqua vending can be completed and at the end of the cycle the water heater is ready for the next cycle of aqua vending.

However, it is possible to supplement the considered aqua vending cycle with one more operation, namely, the operation of ozone disinfection of the inner cavity of chamber 4, which is highly desirable, since a large number of different buyers install their different containers (bottles) into chamber 4, the cleanliness of the outer surface of which is not guaranteed.

To do this, after the buyer, who has already bought water, removes his container with water 12 from chamber 4, when water from source 1 is no longer guaranteed to enter input 8 of branch pipe 6, the controller, blocking the sale of water to the next buyer, reopens valve 3 (if it is electrically controlled valve) and turns on the ozone generator 2 for a specified time (for example, 10 seconds). Ozone flows through the pipeline 11 through the open valve 3 to the inlet 9 of the branch pipe 6 and then to the outlet 7 of this branch pipe and into the chamber 4. As a result, within a given time (10 seconds), the ozone entering the chamber 4 disinfects the internal cavity of this cameras. After the specified time has elapsed, the controller turns off the ozone generator 2 and closes valve 3, after which the water heater is ready to sell water to the next customer. Moreover, for effective disinfection of chamber 4, it is highly desirable to make this chamber with a door.
