Abstract

An appliance single serve beverage dispenser, beverage dispensing assembly, and method of operation is provided. The beverage dispensing assembly may include a brewing body, a shutter door, a lower needle assembly, and an upper needle assembly. The brewing body may define an access aperture and a brew chamber. The brewing body may include a bottom plate defining an outlet into the brew chamber along a delivery axis. The shutter door may be slidably attached to the brewing body. The lower needle assembly may be operably attached to the shutter door and include a lower needle slidably disposed within the brewing body along the delivery axis to move between a retracted position and an extended position. The upper needle assembly may be operably attached to the shutter door and include an upper needle slidably disposed within the brewing body along the delivery axis to move between a retracted position and an extended position.

Claims (47)

1. A beverage dispensing assembly for use with an appliance, the beverage dispensing assembly comprising:

a brewing body defining an access aperture and a brew chamber to receive a brew pod, the brewing body including a bottom plate at a bottom portion of the brew chamber and a top cover at a top portion of the brew chamber, the bottom plate defining an outlet extending into the brew chamber along a delivery axis, the access aperture providing an opening extending radially from the brew chamber through the brew body at a location between the top cover and the bottom plate;

a shutter door slidably attached to the brewing body to move between an open setting and a closed setting, the shutter door positioned across the access aperture in the closed setting;

a lower needle assembly connected to the shutter door, the lower needle assembly including a lower needle slidably disposed within the brewing body along the delivery axis to move between a retracted position and an extended position;

an upper needle assembly connected to the shutter door, the upper needle assembly including an upper needle slidably disposed within the brewing body along the delivery axis to move between a retracted position and an extended position;

a top actuator held within the brewing chamber below the top cover, the top actuator connecting the upper needle assembly and the shutter door to drive the upper needle to the extended position in response to the closed setting of the door; and

a bottom actuator held within the brewing chamber above the bottom plate, the bottom actuator operably connecting the lower needle assembly and the shutter door to drive the lower needle to the extended position in response to the closed setting of the door,

wherein the top actuator includes a set of upper rack teeth along a top circumferential portion of the door, and an upper pinion driveshaft extending between the door and the upper needle assembly, and

wherein the bottom actuator includes a set of lower rack teeth along a bottom circumferential portion of the door, and a lower pinion driveshaft extending between the door and the lower needle assembly.

2. The beverage dispensing assembly of claim 1 , wherein the brewing body defines a circumferential direction perpendicular to the delivery axis, and wherein the shutter door is rotatably disposed about the delivery axis along a portion of the circumferential direction.

3. The beverage dispensing assembly of claim 1 , wherein the bottom actuator is geared to drive the lower needle to the extended position before the top actuator drives the upper needle to the extended position as the shutter door slides to the closed setting.

4. The beverage dispensing assembly of claim 1 , wherein the brewing body includes a pod seat positioned between the bottom plate and the upper needle assembly, the pod seat defining a pin hole coaxial with the outlet.

5. The beverage dispensing assembly of claim 1 , wherein the shutter door includes a pod support extending toward the delivery axis above the bottom plate to support the brew pod within the brew chamber.

6. The beverage dispensing assembly of claim 1 , wherein the upper needle assembly includes an inner seal radially disposed about the upper needle to engage the brew pod in the extended position of the upper needle.

7. The beverage dispensing assembly of claim 1 , further comprising:

a compression spring attached in biased engagement with at least one of the lower needle assembly or the upper needle assembly.

8. The beverage dispensing assembly of claim 1 , further comprising:

an electric actuating motor connected to at least one of the lower needle assembly or the upper needle assembly.

9. A beverage dispensing assembly for use with an appliance, the beverage dispensing assembly comprising:

a brewing body defining an access aperture and a brew chamber to receive a brew pod, the brewing body including a bottom plate at a bottom portion of the brew chamber and a top cover at a top portion of the brew chamber, the bottom plate defining an outlet extending into the brew chamber along a delivery axis, the access aperture providing an opening extending radially from the brew chamber through the brew body at a location between the top cover and the bottom plate;

a shutter door slidably attached to the brewing body to move between an open setting and a closed setting, the shutter door positioned across the access aperture in the closed setting;

an upper needle assembly operably connected to the shutter door, the upper needle assembly including an upper needle slidably disposed within the brewing body along the delivery axis to move between a retracted position and an extended position; and

a top actuator held within the brewing chamber below the top cover, the top actuator connecting the upper needle assembly and the shutter door to drive the upper needle to the extended position in response to the closed setting of the door,

wherein the top actuator includes a set of upper rack teeth along a top circumferential portion of the door, and an upper pinion driveshaft extending between the door and the upper needle assembly.

10. The beverage dispensing assembly of claim 9 , wherein the brewing body defines a circumferential direction perpendicular to the delivery axis, and wherein the shutter door is rotatably disposed about the delivery axis along a portion of the circumferential direction.

11. The beverage dispensing assembly of claim 9 , wherein the shutter door includes a pod support extending toward the delivery axis above the bottom plate to support the brew pod within the brew chamber.

12. The beverage dispensing assembly of claim 9 , wherein the upper needle assembly includes an inner seal radially disposed about the upper needle to engage the brew pod in the extended position of the upper needle.

13. The beverage dispensing assembly of claim 9 , further comprising:

a compression spring attached in biased engagement with the upper needle assembly.

14. A beverage dispensing assembly for use with an appliance, the beverage dispensing assembly comprising:

a brewing body defining an access aperture and a brew chamber to receive a brew pod, the brewing body including a bottom plate at a bottom portion of the brew chamber and a top cover at a top portion of the brew chamber, the bottom plate defining an outlet extending into the brew chamber along a delivery axis, the access aperture providing an opening extending radially from the brew chamber through the brew body at a location between the top cover and the bottom plate;

a shutter door slidably attached to the brewing body to move between an open setting and a closed setting, the shutter door positioned across the access aperture in the closed setting;

a lower needle assembly connected to the shutter door, the lower needle assembly including a lower needle slidably disposed within the brewing body along the delivery axis to move between a retracted position and an extended position;

an upper needle assembly connected to the shutter door, the upper needle assembly including an upper needle slidably disposed within the brewing body along the delivery axis to move between a retracted position and an extended position;

a top actuator held within the brewing chamber, the top actuator connecting the upper needle assembly and the shutter door to drive the upper needle to the extended position in response to the closed setting of the door; and

a bottom actuator held within the brewing chamber, the bottom actuator operably connecting the lower needle assembly and the shutter door to drive the lower needle to the extended position in response to the closed setting of the door,

wherein the brewing body defines a circumferential direction perpendicular to the delivery axis, and wherein the shutter door is rotatably disposed about the delivery axis along a portion of the circumferential direction,
