Description

Field of technology to which the utility model belongs

The utility model relates to aqua vending machines, i.e. to water vending machines by dispensing water into the container of the water buyer by means of a water filling chamber equipped with means for diverting from this chamber the water overflowed in the process of aqua vending into the sewer.

State of the art

As is known, in the process of aqua vending, a predetermined volume of water is automatically dispensed into the container of the water buyer, temporarily placed for this purpose in the water loading chamber, which is part of the aqua vending apparatus. At the same time, often in the process of such issuance, water overflows and this overflowed water must be collected and discharged into the sewer.

Known means for draining overflowed water from the water loading chamber, which consists in making the bottom of the water loading chamber in the form of a reservoir for collecting overflowed water, equipped with a drain pipe (pipeline) for draining overflowed water into the sewer by gravity (see, for example, patents RU: No. 203953 U1, G07F 13/00, published: 28.04.2021 Bulletin No. 13; No. 207954 U1, B67C 3/02, published: 25.11.2021 Bulletin No. 33; No. 208499 U1, G07F 13/00, published: 22.12.2021 Bull. No. 36; No. 2753623 C1, G07F 13/00, published: 18.08.2021 Bull. No. 23).

Known means of draining overflowed water solve the problem of this discharge by gravity, which is impossible in the case of a remote entrance to the sewer, and also when the entrance to the sewer is located above the level of the loading chamber.

The reason preventing in the known technical solutions the discharge of overflowing water into the sewer in a situation where this discharge by gravity is impossible is the lack of means for forced supply of this water into the sewer.

The prototype is a device for pouring water into the container of the buyer of water in the process of aqua-vending, containing a chamber for pouring water into the container of the buyer of water, in the upper part of which there is a pipe for pouring water into the container of the buyer of water, while the bottom of the chamber is made in the form of a tank with a lid that does not interfere with the passage overflowing water into this reservoir and intended for temporary location on this cover of the desired container of the buyer of water with its (container) neck leading under the filling pipe; at the same time, the device is equipped with a pipeline hydraulically connected to the tank for draining overflowed water from this tank into the sewer by gravity (see the description of the patent RU No. 2753623, G07F 13/00, published on August 18, 2021 in Bull. No. 23).

The features of the known device (prototype) that are common with the features of the claimed technical solution are the features of the known device listed above (except for gravity flow).

The reason that prevents the known device (prototype) from obtaining the claimed technical result is the lack of means for forced supply of overflowing water from the water filling chamber to the sewer.

The technical problem to be solved by the technical solution claimed for patenting is the need to create the possibility of forcibly diverting overflowed water from the water filling chamber into the sewer in the case when this diversion is impossible by gravity (remoteness and / or height of the entrance to the sewer).

Disclosure of the essence of the utility model

The technical result, mediating the solution of this technical problem, is to ensure the forced supply of overflowing water from the water filling chamber to the sewer, and such a supply at which the hydraulic seal is automatically maintained and updated in the pipeline for discharging this water, which has an arbitrary configuration, preventing gas exchange between the filling chamber water and sewerage.

The technical result is achieved by the fact that the device for pouring water into the container of the water buyer in the process of aqua vending contains a chamber for pouring water into the container of the water buyer, in the upper part of which there is a branch pipe for pouring water into the container of the water buyer, and the bottom of the chamber is made in the form of a reservoir with a cover made not preventing the passage of overflowed water into the tank and intended for temporary location on the lid of the container of the buyer of water with bringing the neck of the container under the specified branch pipe, while the device also contains a pipeline hydraulically connected to the tank for draining overflowed water from the specified tank into the sewer, a membrane pump hydraulically included in the gap said pipeline, and a pressure switch hydraulically connected to said pipeline before entering the diaphragm pump and electrically connected to the diaphragm pump to turn it on and off.

Brief description of the drawings

The attached figure (without number) schematically shows the claimed device for pouring water into the container of the water buyer in the process of aqua vending.

Implementation of the utility model

The device for pouring water into the container of the water buyer in the process of aqua vending contains a chamber 1 for pouring water into the container 2 of the water buyer. In the upper part of the chamber 1 there is a branch pipe 3 for pouring water. The bottom 4 of the chamber 1 is usually made in the form of a funnel-shaped tank 5 of the bottom of the water filling chamber. At the same time, this tank 5 is provided with a horizontal cover 6 (or a table 6, which in this case is identical to the cover), which is usually perforated and intended for temporary placement of containers 2 on it with the neck of this container brought under the nozzle 3. The tank 5 is designed to collect and discharge overflowed water, for which it is equipped with a pipeline 7 for diverting overflowing water into the sewer. In addition, a membrane (diaphragm) pump 8 is hydraulically included in the break in the pipeline 7, and in the section of this pipeline between the bottom 4 and the pump 8 (i.e., before the inlet to the pump 8 or, which is the same, hydraulically above the pump 8) the pipeline 7 has a branch 9, through which a pressure switch 10 is hydraulically connected to the pipeline 7, electrically connected in turn to the membrane pump 8 for turning it (the pump) on and off in order, on the one hand, to drain the overflowing water from the tank 5 through the pipeline 7 to the sewer , and on the other hand, automatic maintenance and renewal of the water seal 11 in the pipeline 7.

Said water seal 11 is a column of water in pipeline 7 with height h ₁ between the given (upper) level 12 of this water located below the bottom 4 and above the pump 8, and the level 13 of the location of the pump 8 on the pipeline 7 (when this pump is not working and as a result pipeline 7 in this place is blocked by the pump valve 8). In this case, the specified water level 12 in the water seal 11 is determined by setting the pressure switch 10 to the level h ₂ between the given water level 12 and the level 14 of the location of the branch 9, through which the pressure switch 10 is hydraulically connected to the pipeline 7.

The attached figure shows the initial (vertical) section of the pipeline 7, on which (ie, in the vertical section) a pump 8 is installed and a branch 9 for the pressure switch 10 is made. In this case, it is obvious that h ₂ is less than h ₁ . However, the pipeline 7 can have different sections (vertical, horizontal, inclined), so that such a configuration of its (pipeline) sections is possible, when after a short vertical initial section, the pipeline 7 is bent and thereby passes into its horizontal section, and the specified pump 8 and branch 9 are installed precisely on the horizontal section of this pipeline. Under such circumstances, the water seal 11 will be located partly in the vertical section (level 12) and partly in the horizontal section of the pipeline 7 with an emphasis on the idle pump 8, so that in this case there will be an equality between h ₁ and h ₂ .

Thus, in general, h ₂ ≤h ₁ .

The pressure switch, as you know, is a water level sensor widely used in washing machines. The pressure switch contains a water pressure sensitive element and electrical contacts connected to it, which are closed if the water pressure acting on its sensitive element exceeds a predetermined (adjustable) water level, and open if the water pressure acting on its sensitive element is equal to or less than this given water level (https://pikabu.ru/story/ustroystvo_yelektronnogo_pressostata_6938323).

As for the choice of a membrane (diaphragm) pump for the forced supply of water from tank 5 to the sewer, it (the choice) is due to the fact that such a pump has a high efficiency, long service life, maintainability, the ability to create high pressure with minimal cost, low supply voltage electric drive (12 v), which determines the necessary electrical safety when used on water, the ability to hydraulically lock the pipeline when the pump is turned off.

The operation of the device is as follows.

To make a purchase of water, the water buyer installs his container 2 in the chamber 1 for pouring water directly onto the lid (table) 6, bringing the neck of this container under the pipe 3, and starts the process of dispensing water into the container 2 of the water buyer, during which the overflow of water is possible, requiring discharge of overflowing water into the sewer.

The water that has overflowed during the aqua-vending process is collected in the reservoir 5 of the bottom 4 of the water filling chamber 1 and by gravity fills the section of the pipeline 7 until it stops at the initially idle pump 8 in order to further drain this water through the pipeline 7 to the sewer. Thus, at the first moment of time, the actual water level in the pipeline 7 is higher than the predetermined level 12. As a result, the water pressure acting on the pressure switch 10 exceeds the predetermined threshold value and the pressure switch 10 is triggered, as a result of which the corresponding contacts of the pressure switch close and turn on according to this cause of the pump 8. During the operation of the pump 8, water is pumped out of the tank 5 into the sewer through the pipeline 7, but until the actual water level in the pipeline 7 becomes equal to the specified level 12. At this moment (at the moment of equality of these levels) the pressure switch 10 is actuated in the opposite direction, its contacts open as a result and the pump 8 is turned off, thereby hydraulically locking the pipeline 7 at the location of the pump 8. As a result of this shutdown and, as a result, this locking, water remains in the pipeline 7 at section h ₁ this pipeline, thereby forming a water seal 11, preventing harmful g azo exchange between chamber 1 for filling water and sewage. Further, when the overflow of water is repeated, the described cycle is repeated, as a result of which the water seal 11 is updated, which is necessary to prevent the reproduction of harmful microorganisms in it. Thus, in each cycle, two coordinated processes take place: the process of draining overflowed water from the tank 5 and the process of automatically maintaining and updating the water seal 11.
