Abstract

A process for making a hot beverage, such as coffee or tea, includes placing ground coffee or tea into a filter, inserting the filter into a filter basket to support the filter with respect to a reservoir that is to receive a brewed beverage; introducing water into the filter; and repeatedly deforming the filter to alter its shape as water passes through the filter and ground coffee or tea en route to the reservoir. A device for making a hot beverage includes a drive and a filter basket. The filter basket defines a filter basket chamber for receiving an associated filter. The filter basket includes a movable component operably connected to the drive and movable for deforming the associated filter. The movable component is operable between a first operating position where the filter chamber has a first dimension and a second operating position where the filter chamber has a second dimension that is smaller than the first dimension.

Claims

1. A coffee maker comprising:

a drive; and

a filter basket defining a filter basket chamber for receiving an associated coffee filter, the filter basket chamber defining a central vertical axis, the filter basket including a movable component operably connected to the drive, wherein the drive rotates the movable component back and forth about a generally horizontal axis for repeatedly deforming the associated coffee filter, the movable component rotates between a first operating position where the filter basket chamber has a first dimension and a second operating position where the filter basket chamber has a second dimension that is smaller than the first dimension.

2. The coffee maker of claim 1, wherein the filter basket includes a flexible side wall which is the movable component.

3. The coffee maker of claim 2, wherein the flexible side wall is pleated.

4. The coffee maker of claim 1, wherein the movable component is a paddle connected to the filter basket, and the paddle pivots towards the central vertical axis.

5. The coffee maker of claim 1, wherein the first dimension and the second dimension are perpendicular to the central vertical axis.

6. The coffee maker of claim 1, wherein the movable component includes a first movable component and a second movable component, each movable component operably connected to the drive and movable towards an interior of the filter basket chamber.

7. The coffee maker of claim 6, wherein the first movable component is disposed generally opposite to the second movable component.

8. The coffee maker of claim 6, wherein the drive is connected to a cam and the first movable component and the second movable component are each operably connected to the cam.

9. The coffee maker of claim 8, wherein the cam is a dual-lobed cam.

10. The coffee maker of claim 1, wherein the drive includes an electromechanical solenoid, a linear motor or a linear actuator.

18. The coffee maker of claim 4, wherein the axle extends from the paddle.

11. A beverage maker comprising:

a filter basket for receiving an associated coffee filter;

a filter deforming member;

an axle connecting the filter deforming member to the filter basket, the filter deforming member rotating generally horizontally on the axle away from and back towards a side wall of the filter basket; and

a drive operably connected to the filter deforming member for rotating the filter deforming member with respect to the side wall of the filter basket.

12. The beverage maker of claim 11, wherein the filter basket is removable from the beverage maker and the drive operably connects to the filter deforming member upon insertion of the filter basket into the beverage maker.

13. The beverage maker of claim 11, further comprising a cam operably connected to the drive and a lever operably connected to the filter deforming member and contacting the cam, wherein rotational movement of the cam results in pivotal movement of the filter deforming member.

14. The beverage maker of claim 11, wherein the filter basket includes a recess extending outward from an internal surface of the filter basket and the filter deforming member is received in the recess such that the internal surface of the filter basket is substantially flush with an internal surface of the filter deforming member.

15. The beverage maker of claim 11, wherein the filter deforming member includes a curved inner surface that generally follows a radius of a side wall of a conventional cone coffee filter or a conventional basket coffee filter.

16. The beverage maker of claim 11, wherein the filter deforming member includes a first filter deforming member and a second filter deforming member disposed opposite the first filter deforming member.

17. The beverage maker of claim 11, wherein the drive is an electrically powered drive configured to repeatedly deform the associated filter at least about 30 cycles per minute.

19. A coffee maker comprising:

a filter basket defining a filter basket chamber for receiving an associated coffee filter, the filter basket chamber defining a central generally vertical axis, the filter basket including a movable component that rotates about a generally horizontal axis towards and away from the central generally vertical axis; and

a drive operably connected to the movable component for repeatedly deforming the associated coffee filter.

20. The coffee maker of claim 19, wherein the filter basket includes a flexible side wall which is the movable component.

21. The coffee maker of claim 19, wherein the movable component is a paddle connected to the filter basket.

22. The coffee maker of claim 19, wherein the movable component includes a first movable component and a second movable component, each movable component being operably connected to the drive and rotates about a respective generally horizontal axis towards and away from the central generally vertical axis.
