Description

DEVICE FOR PRODUCING CARBONATED WATER
TECHNICAL FIELD The present invention relates to devices known as saturators or carbonators, for producing sparkling water from tap water by adding carbon dioxide.
BACKGROUND ART Carbonation is normally performed by mixing tap water, inside a stainless steel container, with carbon dioxide supplied by cartridges or cylinders.
For effective carbonation, the water and gas pressures must be controlled and maintained by pressure regulators within a precise ratio, which also depends on the temperature of the water. Cold water is normally used, not only to achieve a better mix with the carbon dioxide, but also to prevent the formation of contaminating substances. Currently marketed saturators normally comprise a cylindrical, cup-shaped, stainless steel container closed at the bottom and threaded at the top to screw on a lid, to which all the device operating parts for producing and also dispensing the sparkling water are fitted.
Patent US5792391 describes a device comprising a cylindrical tube closed at one end; and a disk fitted removably to the other end for access to the inside. The disk has water and carbon dioxide inlets, a carbonated water outlet, a safety valve, and a water level sensor, and is held in position by a square metal member, the corners of which cooperate with slits in the cylindrical tube.
SUMMARY OF INVENTION
In view of the increasing popularity of saturators of the type described, and the design restrictions frequently imposed by installation inside cabinets and multipurpose equipment, it is a main object of the present invention to enable manufacture of such devices in a wide range of sizes, but with little investment and stock required. In other words, it is an object of the invention to provide a saturator, which can be adapted easily in size to meet different requirements.
It is a further object of the present invention to make routine cleaning easier and more effective, and to achieve faster, more homogenous mixing of the carbon dioxide and water.
DETAILED DESCRIPTION OF THE DRAWINGS
A number of non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying drawings, in which:
Figure 1 shows a vertical section of an improved device in accordance with the invention;
Figure 2 shows an exploded view in perspective of the Figure 1 device;
Figure 3 shows a vertical section of a further improved device in accordance with the invention;
Figure 4 shows an underside view in perspective of the top cover of the Figure 3 device, equipped with the component parts for producing and dispensing sparkling water.
DETAILED DESCRIPTION OF THE INVENTION
As shown in the accompanying drawings, the outer casing of the devices shown comprises a cylindrical, stainless steel body 1 closed at both ends by removable covers 2 and 3, which are preferably made of plastic and fitted with seals 4, and are fitted to body 1 by means of a central tie 5 and screw means 6, which are fitted to the threaded ends of the tie, and act on covers 2 and 3 from the outside to bring them to rest on the edges of cylindrical body 1.
Alternatively, covers 2, 3 may be fitted to cylindrical body 1 by means of a threaded coupling (i.e. by forming body 1 with threaded ends to which covers, 2,
3 are screwed) or by providing other cover retaining members, as described, for example, in US5792391.
More specifically, as shown in Figures 1, 2 and 3, tie 5 may comprise a screw threaded at both ends and extending longitudinally through body 1; and screw means 6 may comprise two nuts fitted to the ends of the screw and acting on the outside of covers 2, 3. The nut 6 acting on cover 3 is not shown in Figure 1, by being housed inside a recess in cover 3.
Alternatively, tie 5 may comprise a fixed-headed screw extending longitudinally through body 1; and screw means 6 may comprise one nut fitted to the threaded end of the screw such that the fixed head of the screw and the nut act on the outside of covers 2, 3.
Body 1 contains water supplied from the mains through an inlet 7 with a non-return valve 7 ' in the top cover 2, and which is atomized by a nozzle fitted underneath cover 2 and which may be fixed, such as nozzle
20 in Figure 1, or rotary, such as nozzle 30 in Figure 3.
The space above the surface A of the water is permanently filled with pressurized carbon dioxide
(normally at 3-bar pressure) fed from a known cylinder or cartridge through an inlet 8 with a non-return valve 8 ' in top cover 2. Thorough mixing of the water and carbon dioxide depends on the volumetric ratio and pressure ratio between the two, as well as on the temperature of the water. More specifically, the water level A inside body 1 must range between a maximum and minimum value detected by known level sensors 10 and 11 fitted to top cover 2; and the incoming water pressure (normally 5-bar) and carbon dioxide pressure are controlled by known pressure regulators not shown in the drawings .
In the event of overpressure inside body 1, a safety valve 15, fitted to cover 2, is activated to exhaust surplus gas .
The atomized water entering the top of body 1 mixes with the incoming carbon dioxide from inlet 8, and settles on the sparkling water underneath waiting to be drawn from the bottom of body 1 by means of a suction tube 14 connected to an outlet 9 in top cover 2.
The sparkling water is preferably drawn from the bottom of body 1, to prevent CO2 from also being drawn off with the water, as could happen at a higher level.
As water is drawn off and the water level falls below the minimum level detected by sensor 11, a known pump, not shown, feeds in further water to raise level A to the maximum level detected by sensor 10.
In the Figure 1 embodiment, fixed nozzle 20 is fitted inside a sort of bracket 21, which, in the example shown, is C-shaped with its horizontal top portion fixed beneath cover 2, so that the jet breaks against the horizontal portion underneath to disperse the atomized water 360° and mix it with the carbon dioxide between the water and cover 2. In the Figure 3 embodiment, nozzle 30 is hinged inside a bracket 32, and is rotated freely about a vertical pin 31 by the transverse thrust of the incoming water, so that the atomized water descends slowly through and mixes more homogenously with the CO2 to produce high- quality sparking water.
By virtue of the improvements described, the same removable covers 2 and 3 can be used to produce devices of different capacities by simply using cylindrical bodies 1 of the appropriate length and other suitably sized accessory parts such as tie 5 and suction tube 14. Moreover, the possibility of removing both the covers from cylindrical body 1 permits easy inspection and cleaning of the body to ensure the degree of hygiene indispensable for producing any beverage, and also sparkling water.
Clearly, changes may be made to the device as described and illustrated herein without, however, departing from the scope of the present invention.
