Abstract

Various beverage preparation systems and methods are disclosed. The beverage preparation system can include a dispensing unit configured to receive beverage, such as a shot of espresso, from a beverage preparation machine. The dispensing unit can include a dispensing unit with a first end and a second end. The dispensing unit can be rotatable between an upright position and an inverted position. The dispensing unit can be configured to receive the beverage through the second end when the dispensing unit is in the upright position, and can be configured to receive cleansing fluid through the second end when the dispensing unit is in the inverted position. In some embodiments, when the dispensing unit is in an intermediate position between the upright and inverted positions, the dispensing unit is configured to dispense the beverage out of the first end and into a cup or other vessel.

First claim

The following is claimed:

1. A beverage preparation system configured to dispense a beverage into a cup or other drinking vessel, the system comprising:
a beverage preparation machine configured to prepare the beverage;
a dispensing assembly comprising:
a base;
a dispensing unit rotatably coupled to the base, the dispensing unit comprising a hollow elongate shell with an open first end and a second end, the second end comprising a check valve; and
the dispensing unit configured to pivot between an upright position and an inverted position, wherein the first end is substantially directly above the second end in the upright position and the second end is substantially directly above the first end in the inverted position; and

a control valve configured to switch between a first state and a second state, wherein a flow of the beverage is allowed to pass through the control valve in the first state and a flow of cleansing fluid is allowed to pass through the control valve in the second state;
wherein, when the dispensing unit is in the upright position and the control valve is in the first state, the dispensing unit is configured to receive a portion of the beverage through the second end;
wherein, when the dispensing unit is in the inverted position and the control valve is in the second state, the dispensing unit is configured to receive the cleansing fluid through the second end and to dispense the cleansing fluid from the first end; and
wherein, when the dispensing unit is in an intermediate position between the upright and inverted positions, the dispensing unit is configured to dispense the portion of the beverage through the first end and into the cup or other vessel.

2. The system of claim 1 , wherein the dispensing unit is configured to rotate about a pivot axis that is substantially horizontal.

3. The system of claim 1 , wherein the hollow elongate shell of the dispensing unit is configured to disconnect from the check valve.

4. The system of claim 1 , wherein the dispensing unit further comprises a second dispensing unit.

5. The system of claim 4 , further comprising a selector valve configured to switch between allowing the beverage to flow to the dispensing unit and allowing the beverage to flow to the second dispensing unit.

6. The system of claim 1 , wherein:
the check valve is closed when the dispensing unit is in the upright position and the flow of the beverage is less than or equal to a minimum value; and
the check valve is open when the dispensing unit is in the inverted position.

7. The system of claim 1 , wherein the check valve comprises a housing and a ball, the housing comprising an inner chamber with a tapered wall, the ball being positioned in the inner chamber and configured to seat against the tapered wall to close the check valve.

8. The system of claim 7 , wherein the check valve is configured such that at least one of gravity and a spring seats the ball against the tapered wall when the dispensing unit is in the upright position.

9. The system of claim 1 , further comprising a pump configured to encourage the beverage to flow from the beverage preparation machine to the dispensing unit.

10. The system of claim 1 , further comprising a controller configured to control operation of the control valve between the first and second states.

11. The system of claim 1 , wherein the base of the dispensing assembly is configured to mount on a countertop, the countertop having a customer side and a server side, the dispensing unit being located above the countertop and visible from the customer side and the server side.

12. The system of claim 11 , wherein the beverage preparation machine is located below the countertop.

13. The system of claim 1 , wherein the dispensing unit is configured to rotate at least 90° between the upright position and the intermediate position.

14. The system of claim 1 , wherein the dispensing unit is configured to retain the portion of the beverage until the dispensing unit is pivoted from the upright position to the intermediate position.

15. The system of claim 1 , wherein the hollow elongate shell is transparent.

16. The system of claim 1 , wherein the hollow elongate shell further comprises a beverage receiving portion and a mounting portion.

17. The system of claim 16 , wherein the beverage receiving portion is configured to connect to and disconnect from the mounting portion.

18. The system of claim 1 , further comprising a handle that enables a user to manually pivot the dispensing unit.

19. The system of claim 1 , further comprising a sensor configured to detect the temperature of the beverage.

20. The system of claim 1 , wherein the base comprises a second check valve.
