The present invention relates to the water tank for the use of the device for bottling. Water tank contains a section of the bottom and the top surface is located at the distance from the bottom, closed lid, essentially, a cylindrical cavity of the pump, formed in the bottom section with the rotational moving element located around the shaft, situated perpendicular to the bottom section. The booster part of the engine runs from the top Poppet element over the moving element to the cap, which is supported or at least partially supported by the engine. The engine is connected with the moving element through a drive shaft and is located or, at least, partially located in the tank through a hole in the lid.

In such a device, such as water moves from the water tank with a pump in the heating unit, from which warm water moves into the dispenser. Warm water is served to the user and/or one or more devices for preparation of drinks through a distributor. Such a device is e.g described in the patents Netherlands №6000164, №6000166.

Eurasian patent №1245013 and patent №0811345 describe the system that will operate on the basis of the gravitational force and served a constant amount of fluid. Such a system is not suitable for submission of changing quantities of fluid, such as water. Moreover, only a limited amount of fluid can be made per unit of time, using the well-known system.

Another disadvantage of known systems is that always necessary that the different parts were more or less fixed position relative to each other. This means that permanent space must be reserved device with limited freedom of space to use the system, thus limiting the possible options for the design of the device. In particular, the devices for which one of the requirements is that they gave a relatively small amount of drink or water (0,1-0,2 liters) and were able to quickly submit a 1.8 liter jug, these shortcomings are a challenge. Additionally, there are requirements that a device must be so compact (small)as possible, and such devices for filling should prepare a variety of drinks from several different ingredients. The combination of requirements, submission, approximately 0.15 liters to approximately 1.8 liters or more over a relatively short period from 10 to 90 seconds, a few drinks of the water and the few ingredients and very compact design means that the tank and the size of the system should be large enough done very compact and, thus, ensure the optimal use of any space in the device.

However, the known systems have some shortcomings.

Pump, for example, requires a fairly large space for its installation in the device, especially if you want fast pumping of bigger volumes, at least in the case of an automatic device for bottling. This is often to some extent is that require a suitable pump to move fluid consumption, which, probably, is also hot (>82 degrees C).

Switchgear, which is used in conjunction with the pump and must be adaptable to him, also often is relatively large. Additionally, these switchgears usually have problems with air bubbles, which can inhibit the flow, if they are used for larger quantities, about 1.5 liters per minute. For this purpose developed a system for deaeration, unveiled at the European patent №1462040.

Therefore, the aim of the invention consists in the creation of a water reservoir, from which water with relatively high flow rates can be fed into machines for bottling and/or to users. An additional aim of the invention consists in the creation of a reservoir for water with a relatively small size. Also the purpose of the invention consists in the creation of the water tank from which the pump and the moving element can be easily disconnected for the purpose of servicing, inspection and/or replacement.

To achieve these goals, the water tank in accordance with the invention differs in that the working cavity of the pump on the upper surface of the closed round upper disc-type element, supported by a support element in the immediate vicinity of the upper edge of the working cavity of the pump, and the hole in the cap has a diameter exceeding the diameter of the round top Poppet element.

By closing a working cavity of the pump on the upper surface with a round disc element can be provided by a simple engine mounting on a bottom of the tank and the wall cavity pump formed the bottom of container. Round plate element can be placed through the hole in the lid, so no need to disconnect the lid of the reservoir for inspection, maintenance or replacement during the installation of the engine and remove it. Preferably, the engine is installed near the hole and is removable cover, for example, by means of screw thread or bayonet connection type.

In one embodiment moving element contains a base plate, which is joined with the drive shaft and situated on the side facing the engine, deviating blades attached to the base plate. Through the installation of blades on the bottom plate of the water abstracted from the tank and fed into the cavity of the pump, is given in the radial direction of the outlet in the bottom of the working cavity of the pump, the outlet is located on the radial distance from the base plate.

Preferably, a channel for the flow formed in the section of the seabed around the Central section, which is limited to the side walls, and has intake point and point release, which is connected with the outlet located perpendicular to the section of the seabed and the surface of the cross section of the channel for the flow increases from the point of intake towards the point of issue. Thus, there is a spiral of tangential pump, which is achieved by relatively high productivity with the use of pump a small amount.

To direct the flow of water near the point of release to the directed vertically downward outlet deflecting element can be located in the channel for the flow side regarding the district's feed direction for the thread.

The pump in accordance with the invention is described in more detail below, with reference to the accompanying drawings that show the following:

figure 1 shows a schematic view of the device for bottling, which can be applied distributor in accordance with the invention;

Fig. 2 - section tank for water according to figure 1 on line II-II figure 3;

figure 3 - section of the tank in accordance with figure 1 on line III-III figure 2;

figure 4 shows a perspective view of deviant member next to the outlet of the pump casing.

Figure 1 shows the system 1 for bottling beverages, such as coffee makers, tank 2 for water and pump built into the bottom of a tank, heat exchanger 3, distributor 5 and means 6 and 7 for preparation of drinks. When heated to a temperature of approximately 80 C in a heat exchanger 3 water in the tank 2 for water is provided through a pump 4 to the water inlet distributor 5. Consumption may vary from 0.1 to 0.2 liters per minute and is served directly to the user through an outlet 8 or, for example, on one of the devices, 6, 7 for preparation of drinks coffee or other warm drink, similar to the soup. Higher costs may be submitted directly through the outlet 8, for example, in a jar (such as 1,51 per minute), or the device 6, 7 for preparation of drinks.

Figure 2 shows a tank 2 for water with feed means 13. The tank is closed on the top surface of cap 24. At the bottom of the 15 reservoir 2 formed cavity 16 pump vent 17. Moving item 12 in the form of a rotor is located in the cavity of the pump 9, which is driven by a shaft 10 motor 11.

Pump 9 is a pump, centrifugal type and installed near the bottom 15 of the vessel or on it. Rotor 12 pump and the pump is installed in a horizontal plane.

Closing plate item 14 is installed above the rotor 12 with supports 18, 19, who support the shaft 10 and partially engine, which is located at some distance outside the tank over the place.

In the bottom 15 reservoir formed cavity in accordance with the form of the working cavity of the pump, required for the pump.

Closing plate item 14 above the rotor 12 seals the cavity on the upper surface. For the filing of the fluid, such as water, on the rotor 12 closing plate item 14 has holes around the bore for shaft. The level of fluid in the reservoir is maintained at the correct height above the intake ports through the use of well-known means, therefore, they remain permanently below the level of the fluid/water and provide the right (required) submission of a fluid medium.

Rotor 12 contains plate 21, to which is attached upward mounting to the shaft with multiple blades 22 arranged ring configuration around the shaft and directed upwards. As plate is located under 21 rotor provides a proper seal with a bottom of the tank, located at the bottom.

In the end point of the E channel for the flow of a convex edge 30 (figure 4) is located at right angle to the diameter so that the flow of water led down towards the outlet 17. This outlet is additionally provided with a means of deaeration, as described in the European patent №1462040. Through directed down outlet of 17 may perform a tank made of plastic, especially the bottom of the pump housing, located in it, using relatively simple matrix/press-forms and very few additional operations, using readily available production technology. This facilitates effective and economically advantageous production system.

From the point of view of production and maintenance of the whole tank, including pump, the preferred option implementation, therefore, may remain relatively simple.

The finished vessel, i.e. the lower and upper sides established relative to each other, the entire pump 9, including the upper plate item 14, rotor 12 and supports 18, 19, installed through the hole 35 in the cover 24 tank. The engine is attached to the specially formed flange 36 envisioned at its outer edge with bayonet connection screw-threaded type or 37, with the help of which he can be mounted in the hole of the cover, which is equipped for this purpose mate of the bayonet connection type or screw thread.

Flange 36 connected by means of supports 18, 19 with the closing disc-type element 14 above the rotor 12. Once installed, the entire structure is supported in part by the closing disc-type element 14, which, in turn, relies on the edge of 38, passing along the inside of the cavity 16 pump at the bottom of 15, while it is additionally rigidly held in place flange 36 hole in 35 caps 24 reservoir 2.

An outlet of 17 pump 9 is connected directly or indirectly with outlet from the unit, or previously referred to by the distributor with the Central vent. This can pose any one of the configurations listed in the patent 1462040, and its equivalents.
