Description

The technical field to which the invention belongs

The invention relates to aqua vending machines, i. e. to vending machines for water by automatically controlled dispensing of water from a common reservoir into a container (container) of a water buyer.

State of the art

A filling chamber for an aqua vending apparatus is known, containing two side vertical walls, a rear vertical wall, a lid, a bottom made in the form of a grid for draining overflowed water from the chamber, and a filling pipe installed in the upper part of the filling chamber (see description of patent RU No. 62268 U1, IPC G07F 13/00, published: 03/27/2007 Bull. No. 9).

The features of the known filling chamber, common with the features of the claimed technical solution, are that it contains two side vertical walls, a rear vertical wall, a cover, a bottom and a filling pipe installed in the upper part of the loading chamber.

The reason that impedes the achievement of a technical result in the known loading chamber, which is provided by the claimed technical solution, is that in the known chamber, spilled water is removed from the chamber through a grate in the bottom of the chamber, which requires a container with a discharge pipeline to be located under the grate to collect and drain overflowing water, and this, as you know, creates problems during the operation of the device on the street in winter due to icing of the grate.

Known loading chamber for aqua vending apparatus (prototype), containing two side vertical walls, a rear vertical wall, a lid, a bottom made to form a container for overflowing water, a filling pipe installed in the upper part of the filling chamber, a drain pipe installed in the center of the bottom, as well as a table mounted with support on the bottom and made with the possibility of passing through it overflowed water into the specified container for overflowing water, while the table and the bottom are located horizontally and parallel to each other and with a gap between them, so that passage through this gap is ensured overflowing water into the drain pipe (see the description of the utility model to the patent RU 203954 U1, IPC G07F 13/00, published: 04/28/2021 Bull. No. 13).

Signs of a well-known filling chamber (prototype), common with the signs of the claimed technical solution, are that the known chamber contains two side vertical walls, a rear vertical wall, a lid, a bottom made to form a container for overflowing water, a filling pipe installed in the upper parts of the filling chamber, a drain pipe installed in the bottom, as well as a table mounted with support on the bottom and made with the possibility of passing overflowed water into the specified container for overflowing water, while the table is located horizontally and with a gap relative to the bottom, so that passage through this gap overflowed water into the drain pipe.

The technical problem to be solved by the technical solution claimed for patenting is the need to increase the efficiency of protection of the loading chamber from icing in winter due to the possibility of freezing of overflowing water on the elements of the loading chamber. Disclosure of the essence of the invention

The technical result, mediating the solution of this technical problem, is to reduce the time for the release of the overflow water tank from the water overflowed during aquavending, which reduces the likelihood of said icing and reduces the power consumption for heating the bottom of the loading chamber in winter.

The technical result is achieved by the fact that the filling chamber for the aqua vending apparatus contains two side vertical walls, a rear vertical wall, a cover, a bottom made to form a container for overflowing water, a filling pipe installed in the upper part of the loading chamber, a drain pipe installed in the bottom, as well as a table mounted with support on the bottom and made with the possibility of passing overflowed water into the specified container for overflowing water, while the table is located horizontally and with a gap relative to the bottom, so that overflowing water passes through this gap into the drain pipe, and the bottom, in addition, it is located at an acute angle relative to the table, and the drain pipe is located with an offset from the geometric center of the bottom towards the maximum gap.

The technical result is also achieved by the fact that the table is made either in the form of a lattice plate or in the form of a solid plate, the area of which is less than the area of the horizontal cross section of the internal space of the filling chamber; as well as either removable or swivel, or both removable and swivel.

The technical result is also achieved by the fact that the bottom is made in the form of a solid flat plate, in which rectilinear gutters are made by appropriate deformation with the possibility of overflowing water flowing down these gutters into the drain pipe.

The technical result is also achieved by the fact that the bottom is made in the form of a plate bent along the bending line with the formation of two V-shaped planes in cross section with respect to this line with an obtuse angle between these planes, so that the said bending line crosses the inlet of the drain pipe.

The technical result is also achieved by the fact that the bottom is made with the possibility of heating it, so that the chamber contains a heating element located under the bottom with the possibility of heating the bottom.

The technical result is also achieved by the fact that the chamber is equipped with a door made of light-transmitting material, namely, the door is made of monolithic polycarbonate, protected from ultraviolet radiation.

Implementation of the invention

The filling chamber for an aqua vending apparatus contains two side vertical walls (not shown), a rear vertical wall 1 (Fig. 1), a cover 2, a bottom 3 made to form a container 4 for overflowing water, a filling pipe 5 installed in the upper part of the filling chamber , a drain pipe 6 installed in the bottom 3, as well as a table 7 installed with support on the bottom 3 and made with the possibility of passing water into the specified container 4 for overflowing water.

In this case, the table 7 is located horizontally, and the bottom 3 is located at an acute angle a relative to the table 7, i.e. obliquely to the conditional horizontal plane and, as a result, with a variable gap δ between the table 7 and the bottom 3, so that the passage of overflowed water through this gap into the drain pipe 6 is ensured.

The drain pipe 6 is located with an offset from the geometric center of the bottom 3 in the direction opposite to the specified acute angle α, i.e. towards the maximum gap δ (in other words: in the region of the maximum gap δ). In FIG. Figure 1 shows an arrangement of the bottom 3 with the orientation of the angle α to the rear wall 1. However, other orientations of this angle are possible, for example, to one or another side wall of the chamber, or to the front of the chamber (these options are not shown).

Gap δ provides:

1) sloping bottom 3 the function of the container 4 for overflowing water,

2) the passage of overflowing water through this gap into the drain pipe 6 under the action of gravity and due to the inclination of the bottom 3 relative to the conditional horizontal plane towards the pipe 6,

3) heat transfer through the air in this gap δ from bottom 3 to table 7.

Based on these restrictions, the angle α is chosen so that the gap e in its minimum region (in Fig. 1, this is near the rear wall 1) is approximately 4 mm, and in its opposite, maximum region (in Fig. 1, near the front of the chamber ) had a value of approximately 20 mm.

Bottom 3 has three variants of its design.

According to the first version, the bottom 3 is a flat solid plate (Fig. 1).

According to the second version (Fig. 2), the bottom 3 is a flat solid plate, in which, with the help of appropriate deformation, rectilinear gutters 8 are made, which are hydraulically connected with the drain pipe 6 at their ends, so that it is possible for overflowed water to drain through these gutters 8 into the drain nozzle 6. In the embodiment shown in FIG. 2, there are two of these gutters and, converging to the drain pipe 6, they form the Latin letter V. However, there may be more of these gutters.

According to the third option (Fig. 3, 4) the bottom 3 is a solid plate, bent along the bend line 9 with the formation of two planes 10 and 11 relative to this line, forming as a result of this a V-shaped cross-sectional shape of the bottom 3 with an obtuse angle β between planes 10 and 11 of this V-shape. In this case, line 9 crosses the inlet of the drain pipe 6, thereby forming a V-shaped inclined chute for overflowing water to drain along inclined planes 10 and 11, first into the inclined chute formed by line 9, and then along this inclined chute into pipe 6.

Table 7 can be of various design, providing the passage through it or around it of overflowing water into the container 4. Table 7 can be made, for example, in the form of a lattice plate, so that the overflowing water passes into the container 4 through the holes of the lattice of this table, or in the form a solid plate of a smaller area relative to the horizontal cross-sectional area of the internal space of the filling chamber, so that the overflowing water, bypassing the table 7 along its edges, by gravity falls into the container 4 (not shown in the figure).

In addition, for the convenience and efficiency of maintenance of the bottom 3 from its inner side (cleaning from dirt), the table 7 can be made removable and/or rotatable, so that the attendants have the possibility of quick access to the inner surface of the bottom 3.

The chamber also contains a heating element (not shown) located under the bottom 3 with the possibility of heating the bottom 3 to prevent icing of the chamber elements in the winter season. The specified heating element is made, for example, in the form of a heating cable or heating plates, which (which) is directly fixed (are) on the bottom 3 from its lower (outer) side to ensure thermal contact. At the same time, this heating element is covered with heat-insulating material (to reduce heat losses) and connected to an adjustable current source controlled by the controller (the heating element and other elements of the heating system are not shown).

The chamber is also provided with a door (not shown) made of a light-transmitting material, namely, a monolithic polycarbonate protected from ultraviolet radiation. The door, firstly, protects the interior of the chamber from pollution coming from the atmosphere, and the door made of monolithic polycarbonate ensures the strength of this door and its effective light transmission. The door made of UV-protected polycarbonate protects both the door itself from the damaging effects of ultraviolet radiation and those advertising materials that are located on the rear wall 1 of the chamber on the inside of this wall.

The use of the loading chamber is as follows.

The buyer of water, having opened the door, sets the container on table 7, starts the process of dispensing water into the container of the buyer of water. At the same time, the buyer of water through a transparent door exercises visual control of this process. Further, a situation is possible when the buyer, for one reason or another, removes his container from the chamber before the filling process is completed; or he does not do so, but the automation of the aqua vending machine, due to a malfunction in its operation, does not turn off the water supply to the container of the water buyer in time. In this situation, which often occurs, water overflows, due to which in winter this overflowing water can turn into ice on the bottom 3, in the drain pipe 6, on the table 7. To eliminate this possibility, the bottom 3 of the chamber is heated in the device using a heating cable adjacent to the bottom from below (cable not shown), which directly eliminates the possibility of icing the bottom. At the same time, due to the close location of the table 7 relative to the bottom 3, near the back wall 1, the relative heating of this table 7 is also carried out due to the natural convection of heat from the bottom 3 to the table 7, as a result of which the table 7 is not subject to icing. Moreover, other components of the device are not subject to icing, since they do not come into contact with overflowing water, which is ensured by the presence of a container 4 in the lower part of the chamber with a bottom 3 inclined towards the drain pipe 6.

The spilled water is collected in the container 4, but does not linger in it, and along the inclined bottom 3, under the action of gravity, it is rapidly discharged into the sewer through the pipe 6. that in a number of cases (at low negative ambient temperatures) this water does not have time to turn into ice even in the absence of heating of the bottom 3.
