Description

Field of technology to which the invention relates

The invention relates to imported aquavending, i.e. to vending machines for imported drinking water by dispensing this water from an aquarium pre-filled with this water into the container of the water buyer.

State of the art

Imported aqua vending is characterized, as is known, by the automated sale of drinking water through a vending machine (kiosk) designed for this purpose, which has a corresponding aqua reservoir into which imported water is poured, and this water is prepared in a water treatment center and for this reason, in connection with its transportation, it is subjected to repeated transfusion, which can lead to the penetration of foreign solid particles into the water. Thus, firstly, continuous monitoring of the water level in this aquarium tank is necessary so that it does not stand empty, and, secondly, final purification of the water released from the aquarium tank from these particles is necessary. The solution to these problems is known in the prior art.

Thus, an aquatic tank for imported aquavending is known, which is equipped with a water level sensor in this aquatic tank (patent RU No. 137142 U1, IPC G07F13/00, publ. 01.27.2014 Bulletin No. 3, patent holder Crystal Lake LLC, RU). In addition, another aquatic tank for imported aquavending is known, which is also equipped with a water level sensor in this aquatic tank in different possible versions of its (sensor) implementation: float, conductometric, ultrasonic, sensor based on measuring the pressure of the liquid column in the aquatic tank (or in the pipeline ), a sensor based on measuring the weight of an aquarium tank (patent RU No. 107628 U1, IPC G07F7/00, publ. 08/20/2011 Bulletin No. 23, patent holder A.A. Vereshchagin).

Thus, it is widely known to use water tanks equipped with water level sensors in such aquavending, which is a common feature in relation to the claimed water tank.

The reason that prevents the achievement of a technical result in such well-known aquatic tanks, which is ensured by the technical solution declared for patenting, is that in them (known aquatic tanks) the specified sensor performs only its direct function of monitoring the water level in order to minimize periods of downtime of aquatic tanks in imported aquavending. At the same time, another, no less important task, which consists in the final purification of water from foreign particles introduced into it before dispensing water from the aquatic tank, is not solved within the framework of the design of these aquatic tanks.

An aquarium tank for imported aquavending (prototype) is also known, which contains a container [6] with a flat bottom, a drain [7] from overflowing the container with water [6], three water level sensors [9], located in the internal space of the container [6] and interconnected with a vending machine [4], an ozonation device [10] connected to a container [6], wherein a drainage system [11] is installed in the flat bottom of the container [6], supplying water [8] through a pump [12] and a water purification device [13] into a vending machine [4], as well as a filling unit [14], on one side having an outlet into the container [6], and on the other, a connection for filling the container [6] from an external source (see this prototype, namely , description of the floor model and the drawing attached to it with positional designations shown on it, as well as here in square brackets, according to patent RU No. 113043 U1, IPC G07F13/00, published 01/27/2012 Bulletin No. 3, patent holder Bakaleiko V .IN.).

The features of the known aquarium tank (i.e., the specified prototype), common with the features of the technical solution claimed for patenting, are the presence of a container [6], a water level sensor [9], interconnected with a vending machine [4], as well as a drainage system [11] .

The reason that prevents the known aquarium tank (prototype) from obtaining a technical result, which is ensured by the technical solution declared for patenting, is that the bottom of the tank [6] is made flat, the drainage system [11] is installed in the bottom, inside the tank [6] there are three water level sensor [9], providing information about three fixed values of the water level in the tank [6], and the water purification device [13] is a separate unit, not integrated into the tank [6].

The technical problem to be solved by the patented technical solution is the need to simplify the design of the aquatic tank and increase the reliability of imported aquavending by combining two functions in a single design of the aquatic tank: the standard function of a drinking water storage tank directly intended for sale, and the function of the final stage of water purification by releasing the settled water and accumulating this water in the same container.

Disclosure of the essence of the utility model

The technical result that mediates the solution to this technical problem lies in the functional division of all (i.e., the maximum possible inside the aquarium tank) water into two zones: the upper zone 10 of water intended for imported aquavending, and the lower zone 11 of settled water, which performs the function of a purification device water with the possibility of effectively draining this settled water from this zone into the sewer due to the effect of the bottom funnel 2. In this case, this functional separation is carried out by creating a conditional zero water level 9 in the tank 1, specified by the vertical position of the sensor 3 of the tank 1 and provided by the imported aquavending control controller , continuously receiving signals from sensor 3 and accordingly controlling valves 5 and 8 (valve 8 can, as an option, be controlled manually).

The technical result is achieved in that the aqua tank for imported aqua vending contains a tank 1 with a bottom 2, a water level sensor 3 in the tank 1 and an outlet pipe 4 with a controlled outlet valve 5 for dispensing water into the water buyer's container; in this case, the container 1 is made either in the form of a straight cylinder with a bottom 2 in the shape of a corresponding cone, the top 6 of which is oriented downward and in this top 6 a drainage pipe 7 with a controlled drain valve 8 is installed, or in the form of a straight prism with a bottom 2 in the shape of a corresponding pyramid , the top 6 of which is oriented downwards and in this top 6 there is a drain pipe 7 with a controlled drain valve 8. In addition, the specified outlet pipe 4 is installed on the side wall of the container 1 in the lower part of this side wall, and the specified sensor 3 is a primary pressure transducer water into an electrical signal, located outside the internal space of the container 1 and hydraulically connected to the internal space of the container 1 at the level of the lower part of its side wall with the possibility of creating, using a controller associated with the sensor 3 and at least with the outlet valve 5, a conditional zero level 9 water in container 1, functionally dividing the volume of this water into two zones - the upper zone 10 of water intended for imported aquavending, and the lower zone 11 of settled water.

The technical result is also achieved by the fact that the aquarium tank contains a tee 12, through which the sensor 3 is hydraulically connected to the outlet pipe 4 in its section up to the outlet valve 5, so that this sensor 3 through this pipe 4 is hydraulically connected to the internal space of the container 1.

Brief description of the drawing

The attached drawing shows a schematic (in a vertical cross section) image of a tank 1 with a bottom 2 with a functional division of the volume of water in it into two zones - the upper zone 10 of water intended for imported aquavending, and the lower zone 11 of settled water, and also shows the technical means 2÷8 and 12 (except for the imported aquavending control controller mentioned below in this regard), which determine this functional division.

Carrying out the invention

An aquarium tank for imported aquavending contains a container 1, made either in the form of a straight cylinder (option 1), when the guide of the side wall of the container 1 has the shape of a circle (wider - an ellipse), or in the form of a straight prism (option 2), when the guide of the side wall of the container 1 has the shape of a convex polygon, as well as the bottom 2 of this container, made either in the shape of a cone (for the indicated option 1) or in the shape of a pyramid (for the indicated option 2). In this case, in any embodiment of the bottom 2, its top 6 (i.e., either the top 6 of the specified cone, or the top 6 of the specified pyramid) is oriented downward and a drainage pipe 7 with a controlled drain valve 8 is installed in it (at the top 6).

This aqua tank also contains a water level sensor 3 in tank 1, which is a primary converter of water pressure into an analog electrical signal proportional to this pressure, which is informationally connected to the input of the imported aqua vending control controller (the controller is not shown in the drawing). In this case, the sensor 3 is located outside the internal space of the container 1 (so as not to interfere with the periodically carried out process of washing the container 1) and at the same time it is hydraulically connected to the internal space of the container 1 at the level of the lower part of its side wall to enable continuous measurement of the water pressure in this capacity at this level by converting this pressure into a continuous electrical signal sent to the input of the imported aquavending control controller.

This aqua tank also contains an outlet pipe 4 with a controlled outlet valve 5 for dispensing water from tank 1 (from its zone 10) into the container of the water buyer in the process of imported aqua vending. In this case, this pipe 4 is installed on the side wall of the container 1 in the lower part of this side wall (i.e. at level 9 of the lower part of this side wall). In addition (in accordance with the preferred embodiment of the aquarium tank), the outlet pipe 4 contains a tee 12 installed in the section of this pipe up to the valve 5 (i.e. in the section between the side wall of the tank 1 and the valve 5), and through this tee 12 to this The sensor 3 is hydraulically connected to the pipe 4 (hydraulically connected), so that this sensor 3, through this pipe 4, is hydraulically connected to the internal space of the container 1 to be able to continuously measure the water pressure in this container 1 at this level 9 by converting this pressure into a continuous electrical signal, sent to the input of the imported aquavending control controller. However, another option for hydraulic connection of sensor 3 with the internal space of container 1 is also possible, which consists in installing on the side wall of container 1 a separate pipe for sensor 3, intended only for this hydraulic connection of sensor 3 (this option is not shown in the drawing).

In this case, the internal space of the container 1 and the bottom 2 (i.e., the volume of water in this space) is functionally divided into two zones (i.e., divided only by water and without the use of any mechanical partition): the upper water zone 10 for imported aquavending and the lower zone 11 of settled water with the possibility of draining the water in it from this lower zone through the drainage pipe 7 and the drain valve 8, open for this purpose, included in the gap of the pipe 7. Moreover, this separation is carried out by the imported aquavending control controller (not shown) , the input of which is connected to the output of sensor 3, and the output of this controller is connected to the control input of at least valve 5 (possibly valve 8, which can also be manually controlled), so that it (the controller) carries out this separation at a conditional zero level 9 of water in tank 1, which is set by the position of sensor 3 and pipe 4 along the vertical of tank 1, and at the same time it (level 9) functionally divides the volume of water in the aqua tank (tank 1 with bottom 2) into two zones - the upper zone 10 of water for imported aqua-vending and a lower zone 11 of settled water.

The functioning of an aqua tank for imported aqua vending is as follows.

Drinking water prepared in advance and outside the vending machine, using a car equipped with a water tank, is brought to the vending machine having a previously empty container 1 with a bottom 2, and this water is pumped from this tank into this container until it is completely filled, controlled by sensor 3 and a controller for controlling imported aquavending (i.e., they control the water level by water pressure). In this case, valves 5 and 8 are closed. Then the water located in zone 10 is sold, and for this purpose this water is taken from approximately level 9, i.e. from the lower level of this zone 10 through pipe 4 and valve 5, which is opened for this purpose by the control controller for the time specified by this controller. During these sales (as before these sales), the water in container 1 with bottom 2 settles, so that the unwanted solid inclusions present in it settle under their own weight, falling into the lower zone 11 (bottom 2), in which this same settled water, not subject to sale, but subject to effective drainage into the sewer through pipe 7 due to the funnel effect inherent in bottom 2.

As water is sold, the control controller, based on a signal from the output of sensor 3 (i.e., based on the water pressure at level 9), continuously monitors the actual water level in container 1 with bottom 2. And just when this actual water level, gradually decreasing in the process of aquavending, reaches in this decrease the conditional zero level 9 (or approaches it), the specified controller stops aquavending and gives a signal to the service personnel about the need for the next delivery. At the same time, if necessary, the specified controller opens valve 8 (or this valve manually opens the working one) and thereby completely discharges water from zone 11 through pipe 7 into the sewer, and also, if necessary, flushes zone 10 (and at the same time and zone 11) by supplying flushing water to container 1 from above while simultaneously discharging it from container 1 through pipe 7 and open valve 8. In this case, the effectiveness of the said discharge and flushing is ensured by the relatively high speed and turbulence of water flow from container 1, caused by the bottom funnel effect 2.

Then the next cycle of imported aquavending is carried out, repeating the technological operations described above.
