Implementation of the utility model

A loading chamber for an aqua vending machine 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 loading pipe 5 installed in the upper part of the loading 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 α relative to the table 7, i.e. obliquely to the conditional horizontal plane and, as a result, with a variable gap S between the table 7 and the bottom 3, so that the passage of the overflowing water through this gap into the drain pipe 6 is ensured.

The drain 6 is disposed 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 clearance 3 (in other words: in the region of the maximum clearance β. Fig. 1 shows a variant of the location 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 camera (these options are not shown).

Clearance 3 provides:

1) an inclined bottom 3 function of a 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 3, from the bottom 3 to the table 7.

Based on these restrictions, the angle α is chosen such that the gap 3 in its minimum region (in Fig. 1 it is near the rear wall 1) has a value of approximately 4 mm, and in its opposite, maximum region (in Fig. 1 - near the front of the chamber ) was about 20 mm.

The bottom 3 has three options for 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, by means of appropriate deformation, rectilinear grooves 8 are made, which at their ends are hydraulically connected to the drain pipe 6, so that it is possible for the overflowing water to drain through these grooves 8 into the drain branch pipe 6. In the embodiment shown in FIG. 2, there are two of these gutters and they, converging to the drain pipe 6, thereby form the Latin letter V. However, there may be more of these gutters.

According to the third version (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, resulting in a V-shaped cross-section of the bottom 3 with an obtuse angle β between planes 10 and 11 of this V-shape. In this case, line 9 intersects the inlet of the drain pipe 6, thereby forming a V-shaped inclined chute for draining the overflowing water along the inclined planes 10 and 11, first into the inclined chute formed by line 9, and then along this inclined chute into the pipe 6.

The table 7 can have a different design, providing the passage of overflowing water through it or around it into the container 4. The 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 grate of this table, or in the form a solid plate of a smaller area relative to the area of the horizontal cross-section of the inner space of the filling chamber, so that the overflowing water, bypassing the table 7 along its edges, flows by gravity into the container 4 (not shown in the figure).

In addition, for the convenience and efficiency of servicing the bottom 3 from its inner side (cleaning from dirt), the table 7 can be removable and / or rotatable, so that the service personnel have the ability to quickly access the inner surface of the bottom 3.

The chamber, in addition, 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 are (which) are directly fixed (fixed) on the bottom 3 from its lower (outer) side with the provision of thermal contact. In this case, this heating element is covered with a heat-insulating material (to reduce heat loss) and is 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 light-transmitting material, namely, monolithic polycarbonate protected from ultraviolet radiation. The door, firstly, protects the inner space of the chamber from contaminants coming from the atmosphere, and the door made of monolithic polycarbonate ensures the strength of this door and its effective light transmittance. The door is made of polycarbonate, protected from ultraviolet radiation, protects both the door itself from the destructive action of ultraviolet radiation, and those advertising materials that are located on the rear wall of the chamber 1 from the inner side of this wall.

The use of the loading chamber is as follows.

The buyer of water, opening the door, sets the container on table 7, starts the process of dispensing water into the container of the buyer of water. In this case, the buyer of water through a transparent door visually controls 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 ends; or he does not do this, but the automatic equipment of the aquavending apparatus, 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 overflow occurs, 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 exclude this possibility, the bottom of the chamber 3 is heated in the device using a heating cable adjacent to the bottom from below (cable not shown), which directly excludes the possibility of bottom icing. In this case, due to the close location of the table 7 relative to the bottom 3 near the rear wall 1, relative heating of this table 7 is 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 exposed to icing, since they do not come into contact with the overflowing water, which is ensured by the presence in the lower part of the chamber of a container 4 with a bottom 3 inclined to the drain pipe 6.

The spilled water is collected in the tank 4, but does not stay in it, but along the inclined bottom 3, under the influence of gravity, it is rapidly discharged into the sewer through the pipe 6. Thus, it is the execution of the bottom 3 inclined relative to the conditional horizontal plane that accelerates the drainage of the overflowing water into the sewer, so that in some cases (at low negative ambient temperatures) this water does not have time to turn into ice even in the absence of bottom heating 3.
