Abstract

An autofill pitcher system includes a pitcher and a dispenser. The pitcher includes at least one pitcher wall and an internal volume defined within the at least one pitcher wall. The dispenser defines a cavity. The cavity is configured to receive the pitcher. The dispenser also includes a fill tube and a pod receiver. The fill tube is positioned and configured to direct a flow of water from a water supply into the internal volume of the pitcher when the pitcher is received within the cavity. The pod receiver is configured to hold a pod containing an additive. The pod receiver is in fluid communication with the internal volume of the pitcher whereby the dispenser is configured to provide the additive to the internal volume of the pitcher.

Claims (20)

1 . A refrigerator appliance comprising:

a cabinet defining a fresh food chamber;

an autofill pitcher system comprising:

a pitcher comprising at least one pitcher wall and an internal volume defined within the at least one pitcher wall;

a dispenser defining a cavity, the cavity configured to receive the pitcher, the dispenser comprising a fill tube and a pod receiver configured to hold a pod containing an additive, the fill tube positioned and configured to direct a flow of water from a water supply into the internal volume of the pitcher when the pitcher is received within the cavity, the pod receiver in fluid communication with the internal volume of the pitcher whereby the dispenser is configured to provide the additive to the internal volume of the pitcher; and

a dispensing tube extending from the pod receiver to an outlet of the dispensing tube, the outlet of the dispensing tube positioned and oriented to direct a flow of additive into the internal volume of the pitcher without the liquid additive passing through any other intervening structures of the dispenser.

2 . The refrigerator appliance of claim 1 , further comprising a dosing pump coupled to the pod receiver, wherein the dosing pump is configured to urge additive from the pod to the internal volume of the pitcher.

3 . The refrigerator appliance of claim 2 , further comprising a valve between the dosing pump and the internal volume of the pitcher, wherein the valve is movable between an open position and a closed position, the valve configured to permit additive flow when in the open position and to obstruct additive flow when in the closed position.

4 . The refrigerator appliance of claim 2 , wherein the dosing pump is a peristaltic pump.

5 . The refrigerator appliance of claim 4 , wherein the peristaltic pump is actuated by a stepper motor.

6 . The refrigerator appliance of claim 1 , wherein the pod receiver is a first pod receiver configured to hold a first pod containing a first additive, further comprising a second pod receiver configured to hold a second pod containing a second additive.

7 . An autofill pitcher system comprising:

a pitcher comprising at least one pitcher wall and an internal volume defined within the at least one pitcher wall;

a dispenser defining a cavity, the cavity configured to receive the pitcher, the dispenser comprising a fill tube and a pod receiver configured to hold a pod containing an additive, the fill tube positioned and configured to direct a flow of water from a water supply into the internal volume of the pitcher when the pitcher is received within the cavity, the pod receiver in fluid communication with the internal volume of the pitcher whereby the dispenser is configured to provide the additive to the internal volume of the pitcher; and

a dispensing tube extending from the pod receiver to an outlet of the dispensing tube, the outlet of the dispensing tube positioned and oriented to direct a flow of additive into the internal volume of the pitcher without the liquid additive passing through any other intervening structures of the dispenser.

8 . The autofill pitcher system of claim 7 , further comprising a dosing pump coupled to the pod receiver, wherein the dosing pump is configured to urge additive from the pod to the internal volume of the pitcher.

9 . The autofill pitcher system of claim 8 , further comprising a valve between the dosing pump and the internal volume of the pitcher, wherein the valve is movable between an open position and a closed position, the valve configured to permit additive flow when in the open position and to obstruct additive flow when in the closed position.

10 . The autofill pitcher system of claim 8 , wherein the dosing pump is a peristaltic pump.

11 . The autofill pitcher system of claim 10 , wherein the peristaltic pump is actuated by a stepper motor.

12 . The autofill pitcher system of claim 7 , wherein the pod receiver is a first pod receiver configured to hold a first pod containing a first additive, further comprising a second pod receiver configured to hold a second pod containing a second additive.
