Abstract

A beverage dispensing apparatus including a storage tank. At least one ice body is formed proximate the top portion of the storage tank. The ice body is formed in an icemaker configured to produce an ice body through direct contact with an evaporator coil and does not use cold air, or formed directly on a portion of the top portion of the storage tank using evaporator coils extending around a perimeter of the storage tank. The water is then configured to be carbonated and then dispensed to a user upon a user command.

First claim

What is claimed is:

1. A beverage dispensing apparatus comprising:
a liquid inlet configured to receive water from a water source;
a storage tank that receives water from the liquid inlet and having a top portion and a bottom portion;
at least one ice body proximate the top portion of the storage tank, and wherein the at least one ice body is formed in an icemaker configured to produce an ice body through direct contact with an evaporator coil and does not use cold air, or formed directly on a portion of the top portion of the storage tank using evaporator coils extending around a perimeter of the storage tank;
a carbonator configured to produce carbonated water received via a fluid conduit from the storage tank; and
a pump configured to pump the water from the bottom portion of the storage tank, through the carbonator, and to dispense the water or a carbonated beverage to a user, upon a user command.

2. The beverage dispensing apparatus of claim 1 , wherein the storage tank is comprised of a plastic polymer and the storage tank is a double-walled insulated storage tank.

3. The beverage dispensing apparatus of claim 1 , wherein the carbonator is an in-line, on demand carbonator.

4. The beverage dispensing apparatus of claim 1 , wherein the icemaker is configured to dispense the at least one ice body directly to a user.

5. The beverage dispensing apparatus of claim 1 , wherein water from the bottom portion of the storage tank is dispensed directly to the user, without passing through the carbonator.

6. The beverage dispensing apparatus of claim 1 , wherein at least the bottom portion of the storage tank is mostly free of ice.

7. The beverage dispensing apparatus of claim 1 , wherein the top portion of the storage tank includes a plurality of liquid inlets disposed about a perimeter of the storage tank and configured to dispense water radially inward.

8. The beverage dispensing apparatus of claim 1 , wherein the storage tank is configured to maintain the water in the bottom portion of the tank at a coldest possible temperature without freezing.

9. The beverage dispensing apparatus of claim 1 , wherein the bottom portion of the storage tank is free from a component that removes heat.

10. A beverage dispensing apparatus comprising:
a liquid inlet configured to receive water from a water source;
a storage tank that receives water from the liquid inlet and having a top portion and a bottom portion;
at least one ice body proximate the top portion of the storage tank, and wherein the at least one ice body is formed in an icemaker configured to produce an ice body through direct contact with an evaporator coil and does not use cold air, or formed directly on a portion of the top portion of the storage tank using evaporator coils extending around a perimeter of the storage tank; and
a pump configured to pump the water from the bottom portion of the storage tank, to a user, upon a user command.

11. The beverage dispensing apparatus of claim 10 , wherein the top portion of the storage tank includes a plurality of liquid inlets disposed about a perimeter of the storage tank and configured to dispense water radially inward.

12. The beverage dispensing apparatus of claim 10 , wherein the storage tank is configured to maintain the water in the bottom portion of the storage tank at a coldest possible temperature without freezing.

13. The beverage dispensing apparatus of claim 10 , wherein the bottom portion of the storage tank is free from a component that removes heat.

14. A method for producing a beverage comprising the steps of:
providing a liquid inlet configured to receive water from a water source;
receiving water into a storage tank from the liquid inlet, wherein the storage tank has a top portion and a bottom portion;
forming at least one ice body proximate the top portion of the storage tank, wherein the bottom portion of the storage tank is mostly free of ice; and where at least one ice body is formed in an icemaker configured to produce an ice body through direct contact with an evaporator coil and does not use cold air, or formed directly on a portion of the top portion of the storage tank using evaporator coils extending around a perimeter of the storage tank;
pumping the water from the bottom portion of the storage tank;
dispensing the water to a user upon a user command.

15. The method of claim 14 , further comprising dispensing the at least one ice body directly to a user.

16. The method of claim 14 , further comprising carbonating the water with a carbonator prior to dispensing the water, wherein the carbonator is an in-line, on demand carbonator.

17. The method of claim 14 , further comprising filtering the water from the water source.

18. The method of claim 14 , wherein evaporator coils are disposed solely on the top portion of the storage tank.
