Dispensing assembly for a refrigerator appliance
A dispensing assembly for a refrigerator appliance is provided. The dispensing assembly includes a tank that defines a fluid chamber and a heating element for heating fluid within the fluid chamber. An inlet conduit directs liquid into the fluid chamber, a first outlet conduit directs liquid out of the fluid chamber, and a second outlet conduit directs gas out of the fluid chamber. The dispensing assembly also includes valves for regulating fluid flow through the inlet conduit and the first and second outlet conduits.
1. A refrigerator appliance, comprising:
a cabinet defining a chilled chamber for receiving food or beverage items for storage, the cabinet also defining an opening for accessing the chilled chamber;
a door mounted to the cabinet at the opening of the cabinet, the door defining a dispenser recess; and
a dispensing assembly comprising
a tank defining a fluid chamber;
a heating element configured for heating fluid within the fluid chamber of the tank;
an inlet conduit configured for directing liquid into the fluid chamber of the tank;
a first outlet conduit extending between the tank and the dispenser recess of the door, the first outlet conduit configured for directing liquid out of the fluid chamber of the tank to the dispenser recess of the door;
a first outlet valve coupled to the first outlet conduit, the first outlet valve configured for regulating a flow of liquid through the first outlet conduit out of the fluid chamber of the tank;
a second outlet conduit extending between the tank and the dispenser recess of the door, the second outlet conduit configured for directing gas out of the fluid chamber of the tank to the dispenser recess of the door;
a second outlet valve coupled to the second outlet conduit, the second outlet valve configured for regulating a flow of gas through the second outlet conduit out of the fluid chamber of the tank.
2. The refrigerator appliance of claim 1 , further comprising a controller in operative communication with the heating element and the first and second outlet valves, the controller configured for
selectively activating the heating element in order to heat fluid within the fluid chamber of the tank;
selectively adjusting the first outlet valve between an open configuration and a closed configuration, the first outlet valve permitting the flow of liquid through the first outlet conduit out of the fluid chamber of the tank to the dispenser recess of the door when the first outlet valve is in the open configuration, the first outlet valve hindering the flow of liquid through the first outlet conduit out of the fluid chamber of the tank when the first outlet valve is in the closed configuration; and
selectively switching the second outlet valve between an open configuration and a closed configuration, the second outlet valve permitting the flow of gas through the second outlet conduit out of the fluid chamber of the tank to the dispenser recess of the door when the second outlet valve is in the open configuration, the second outlet valve hindering the flow of gas through the second outlet conduit out of the fluid chamber of the tank when the second outlet valve is in the closed configuration.
3. The refrigerator appliance of claim 2 , further comprising a control panel having at least one user input, the controller being in communication with the control panel.
4. The refrigerator appliance of claim 3 , wherein the controller is configured for:
receiving a hot water activation signal from the control panel;
activating the heating element in order to heat fluid within the fluid chamber of the tank based at least in part on the hot water activation signal from said step of receiving;
adjusting the first outlet valve to the open position in order to initiate a flow of heated liquid to the dispenser recess of the door through the first outlet conduit; and
shifting the first outlet valve to the closed position in order to terminate the flow of heated liquid to the dispenser recess of the door through the first outlet conduit.
5. The refrigerator appliance of claim 3 , wherein the controller is configured for:
receiving a steam activation signal from the control panel;
activating the heating element in order to heat fluid within the fluid chamber of the tank based at least in part on the steam activation signal from said step of receiving;
adjusting the second outlet valve to the open position in order to initiate a flow of heated gas to the dispenser recess of the door through the second outlet conduit; and
shifting the second outlet valve to the closed position in order to terminate the flow of heated gas to the dispenser recess of the door through the second outlet conduit.
6. The refrigerator appliance of claim 1 , further comprising a nozzle positioned within the dispenser recess of the door, the nozzle being in fluid communication with the second outlet conduit and configured for receiving gas from the second outlet conduit.
7. The refrigerator appliance of claim 6 , wherein the nozzle is rotatably or slidably mounted within the dispenser recess of the door such that the nozzle is configured for placement within a container.
8. The refrigerator appliance of claim 1 , wherein the second outlet valve comprises a solenoid valve or a spring-loaded check valve.
9. The refrigerator appliance of claim 1 , wherein the first outlet valve comprises a solenoid valve.
10. The refrigerator appliance of claim 1 , further comprising a shield mounted to the door at the dispenser recess of the door, the shield selectively sealing the dispenser recess of the door in order to assist gas from the second conduit with sanitizing the dispenser recess of the door.
