Abstract

An apparatus for providing carbonating of water. The apparatus including a carbonating tank having a carbon dioxide inlet, a water inlet, and a carbonated water outlet. The carbonating tank is pivotally mounted to a rigid structure and connected to an electric motor for providing an undulating or rocking motion of the carbonator about its pivot mounting. The motion of the carbonating tank providing for carbonating of the water held therein.

Claims

1. An apparatus for carbonating water, comprising:

a carbonating tank, the carbonating tank having a first inlet for connecting to a source of pressurized carbon dioxide, a second inlet for connecting to a pressurized source of potable water, a carbonated water outlet for connecting to one or more valve means for dispensing carbonated water produced in the tank, means for regulating filling of the tank with the potable water in response to the withdrawal of water from the carbonating tank, and pivot support means for the carbonating tank for retaining the carbonating tank so that it can be moved in a reciprocating manner about an axis, and a drive means connected to a reciprocating means and the reciprocating means connected to the carbonating tank so that operating of the drive means provides for imparting a reciprocating motion to the carbonating tank about the axis so that motion is imparted to the water held within the carbonating tank for facilitating carbonating of the water.

2. The carbonating apparatus as defined in claim 1, and the means for regulating filling comprising water valve means connected to the water inlet, carbon dioxide valve means connected to the carbon dioxide inlet and a vent valve connected to a vent outlet of the carbonating tank and the carbonating tank having high and low water level sensing means, and control means, the control means connected to the high and low sensing means and to the water, carbon dioxide and vent valves for providing operating thereof in response to the level sensed by the level sensing means for regulating the filling of the carbonating tank with water.

3. The carbonating apparatus as defined in claim 1, and further including means for cooling the carbonating tank.

4. The carbonating apparatus as defined in claim 1, and further including means for pre-cooling the potable water delivered to the carbonating tank water inlet.

5. The carbonating apparatus as defined in claim 1, and the carbonating tank being elongate and extending from a first end to a second end and the pivot support means secured to the tank first end and to a support structure.

10. The carbonating apparatus as defined in claim 2, and further including means for cooling the carbonating tank.

11. The carbonating apparatus as defined in claim 10, and further including means for pre-cooling the potable water delivered to the carbonating tank water inlet.

6. An apparatus for carbonating water, comprising:

a carbonating tank, the carbonating tank having a first inlet for connecting to a source of pressurized carbon dioxide, a second inlet for connecting to a source of potable water, a carbonated water outlet for connecting to one or more valve means for dispensing carbonated water produced in the tank,

means for regulating filling of the tank with the potable water in response to the withdrawal of carbonated water from the tank, the means for regulating filling comprising water valve means connected to the water inlet, carbon dioxide valve means connected to the carbon dioxide inlet and a vent valve connected to a vent outlet of the carbonating tank and the carbonating tank having high and low water level sensing means, and control means, the control means connected to the high and low sensing means, to the water valve means, and to the carbon dioxide and vent valves for providing operating thereof in response to the level sensed by the level sensing means for regulating the filling of the carbonating tank with water, and pivot support means for the carbonating tank for retaining the carbonating tank so that it can be moved in a reciprocating manner about an axis, and a drive means connected to a reciprocating means and the reciprocating means connected to the carbonating tank so that operating of the drive means provides for imparting a reciprocating motion to the carbonating tank about the axis so that motion is imparted to the water held within the carbonating tank.

7. The carbonating apparatus as defined in claim 6, and further including means for cooling the carbonating tank.

8. The carbonating apparatus as defined in claim 6, and further including means for pre-cooling the potable water delivered to the carbonating tank water inlet.

9. The carbonating apparatus as defined in claim 6, and the motion imparting means comprising a pivotal support means for the carbonating tank and drive means connected to the carbonating tank for moving the carbonating tank about the pivotal support.

12. A method for carbonating water, comprising the steps of:

pivotally securing a carbonating tank to a support structure, filling the carbonating tank partially with water, applying a head of pressurized carbon dioxide to the water held within the carbonating tank, and moving the carbonating tank in a reciprocating motion about an axis for imparting a motion to the water within the carbonator for facilitating carbonating of the water.

13. The method as defined in claim 12, and the carbonating tank being elongate and extending from a first end to a second end, and the tank pivotally secured on the tank first end to a support structure wherein the tank extends in a substantially horizontal orientation and the tank moved in a reciprocating motion between a low position and a high position about a horizontal axis extending through the pivotally secured first end in a direction substantially transverse to the extension of the tank.

14. The method as defined in claim 13, and the reciprocating motion providing for propagating a wave in the water held in the carbonating tank, the wave flowing alternately between the ends of the tank as the tank is reciprocated about the horizontal axis between the high and low positions.

15. The method as defined in claim 14, wherein the carbonating tank is moved in a reciprocating motion at a rate wherein the time required for a wave to be propagated from either tank end to the opposite tank end is substantially equal to the time that is required to move the tank between the high and low positions.

16. An apparatus for carbonating water, comprising:

a carbonating tank, the carbonating tank having a first inlet for connecting to a source of pressurized carbon dioxide, a second inlet for connecting to a pressurized source of potable water, and a carbonated water outlet, pivot support means for the carbonating tank for retaining the carbonating tank so that it can be moved in a reciprocating manner about an axis, and a drive means connected to a reciprocating means and the reciprocating means connected to the carbonating tank so that operating of the drive means provides for imparting a reciprocating motion to the carbonating tank about the axis so that motion is imparted to the water held within the carbonating tank for facilitating carbonating of the water.

17. The carbonating apparatus as defined in claim 16, and the carbonating tank being elongate and extending from a first end to a second end and the pivot support means secured to the tank first end and to a support structure wherein the tank extends in a substantially horizontal orientation and is reciprocated between a low position and a high position about the axis, the axis being a horizontal axis extending through the pivot means in a direction substantially transverse to the extension of the tank wherein operating of the drive means and reciprocating means provides for operating the carbonating tank so that a wave is propagated in the water therein, the wave flowing alternately between the ends of the tank as the tank is reciprocated about the horizontal axis between the high and low positions.

18. The apparatus as defined in claim 17, and further comprising control means connected to the drive means for reciprocating the carbonating tank at a rate wherein the time required for a wave to be propagated from either tank end to the opposite tank end is substantially equal to the time that is required to move the tank between the high and low positions.
