Icemaker appliance
An icemaker appliance is provided, the icemaker appliance including an upper reservoir positioned above a lower reservoir along a vertical axis. The upper reservoir is positioned at least partially overlapping an icemaking vessel along the vertical axis. A pump is configured to flow water through a first conduit from the lower reservoir. A second conduit fluidly couples the pump to the upper reservoir. A supply conduit is fluidly coupled the upper reservoir to the icemaking vessel.
1 . An icemaker appliance, comprising:
an upper reservoir positioned above a lower reservoir along a vertical axis, the upper reservoir positioned at least partially overlapping an icemaking vessel along the vertical axis;
a pump configured to flow water through a first conduit from the lower reservoir, wherein the first conduit is directly fluidly coupled from the lower reservoir to the pump;
a second conduit fluidly coupling the pump to the upper reservoir and a supply conduit, the supply conduit fluidly coupling the upper reservoir to the icemaking vessel, wherein the second conduit is fluidly coupled from the pump to the upper reservoir and the supply conduit via a tee.
2 . The icemaker appliance of claim 1 , wherein a drain conduit is extended from the supply conduit, the drain conduit in fluid communication with a drain plug.
3 . The icemaker appliance of claim 1 , wherein the second conduit is configured to generate a second conduit pressure greater than a supply conduit pressure at the supply conduit.
4 . The icemaker appliance of claim 1 , wherein the lower reservoir, the first conduit, the pump, the second conduit, and the upper reservoir are in serial flow communication.
5 . The icemaker appliance of claim 4 , comprising:
a drain conduit extended from the supply conduit; and
a drain plug fluidly coupled to the drain conduit.
6 . The icemaker appliance of claim 4 , comprising:
an exit chute providing fluid communication from an exit opening of the icemaking vessel to an ice reservoir.
7 . The icemaker appliance of claim 6 , wherein the ice reservoir is in direct fluid communication with the lower reservoir.
8 . The icemaker appliance of claim 6 , wherein the exit opening is positioned above the upper reservoir along the vertical axis.
9 . The icemaker appliance of claim 1 , comprising:
a controller configured to selectively operate the pump and the icemaking vessel, the controller configured to:
allow a temperature at the icemaking vessel to be above freezing temperature of water at the conduit; and
operate the pump to flow water through a closed loop circuit comprising the lower reservoir, the first conduit, the pump, the second conduit, the upper reservoir, and the icemaking vessel.
10 . The icemaker appliance of claim 9 , the controller configured to operate the pump to flow water through the closed loop circuit after the temperature at the icemaking vessel is above freezing temperature of water at the conduit.
11 . The icemaker appliance of claim 9 , the controller configured to:
operate the pump to flow water through the closed loop circuit for a plurality of cycles through the closed loop circuit.
12 . The icemaker appliance of claim 11 , the controller configured to:
operate the pump to flow water through the closed loop circuit for a plurality of cycles through the closed loop circuit until ice at an ice reservoir is removed.
13 . The icemaker appliance of claim 9 , the controller configured to:
drain the water through a drain plug after completing a plurality of cycles of flowing water though the closed loop circuit.
14 . The icemaker appliance of claim 9 , the controller configured to:
build a water height at the upper reservoir to approximately an equal level to a height of the icemaking vessel.
15 . The icemaker appliance of claim 14 , the controller configured to:
egress water from the icemaking vessel to the ice reservoir via an exit opening at the icemaking vessel, the exit opening at an approximately equal height to the height of the icemaking vessel.
16 . The icemaker appliance of claim 9 , the controller configured to:
discontinue operation of a heat exchanger system to allow a temperature at the icemaking vessel to be above freezing temperature of water at the conduit;
drain the water through a drain plug after completing a plurality of cycles of flowing water though the closed loop circuit; then
restart operation of the heat exchanger system.
17 . The icemaker appliance of claim 9 , wherein the closed loop circuit comprises a flowpath formed between a cylinder and an auger at the icemaking vessel.
18 . The icemaker appliance of claim 1 , wherein the icemaker appliance is a nugget icemaker appliance.
