Drainless clear ice maker for recycling water used to make clear ice
An icemaker appliance includes a first reservoir, a second reservoir, a first circulation system associated with the first reservoir, and a second circulation system associated with the second reservoir. Liquid in the first reservoir is directed toward a first set of ice molds and liquid from the second reservoir is directed toward a second set of ice molds. Liquid in the first reservoir is selectively supplied to the second reservoir.
1. An icemaker appliance defining a vertical direction, a lateral direction, and a transverse direction, the icemaker appliance comprising:
a cabinet comprising an ice storage compartment defined therein;
a first ice mold and a second ice mold provided above the ice storage compartment;
a first reservoir provided within the ice storage compartment;
a first circulation system provided in the first reservoir, the first circulation system configured for supplying a first liquid from the first reservoir to the first ice mold during a first icemaking cycle, the first liquid containing a first concentration of total dissolved solids (TDS);
a second reservoir provided within the ice storage compartment, the second reservoir being in fluid communication with the first reservoir; and
a second circulation system provided in the second reservoir, the second circulation system configured for supplying a second liquid from the second reservoir to the second ice mold during a second icemaking cycle, the second liquid containing a second concentration of TDS greater than the first level of TDS, wherein the second liquid comprises at least a portion of the first liquid transferred to the second reservoir after the first icemaking cycle.
2. The icemaker appliance of claim 1 , wherein the first circulation system comprises:
a first circulation conduit;
a first pump connected to the first circulation conduit to pump the liquid from the first reservoir through the first circulation conduit; and
a nozzle downstream from the first circulation conduit to dispense the liquid from the first circulation conduit toward the first ice mold.
3. The icemaker appliance of claim 1 , wherein the second circulation system comprises:
a second circulation conduit;
a second pump connected to the second circulation conduit to pump the liquid from the second reservoir through the second circulation conduit; and
a nozzle downstream from the second circulation conduit to dispense the liquid from the second circulation conduit toward the second ice mold.
4. The icemaker appliance of claim 1 , wherein the second reservoir is lower than the first reservoir along the vertical direction.
5. The icemaker appliance of claim 4 , further comprising a valve provided between the first reservoir and the second reservoir, the valve selectively allowing the liquid to flow from the first reservoir to the second reservoir.
6. The icemaker appliance of claim 1 , wherein the ice storage compartment is partitioned into a first ice storage compartment and a second ice storage compartment.
7. The icemaker appliance of claim 6 , wherein the first ice mold comprises a plurality of first ice molds and the second ice mold comprises a plurality of second ice molds, and wherein ice formed from the plurality of first ice molds is directed into the first ice storage compartment and ice formed from the plurality of second ice molds is directed into the second ice storage compartment.
8. The icemaker appliance of claim 1 , wherein the ice maker comprises a sealed cooling system in communication with the first and second ice molds, the sealed cooling system having an evaporator positioned at the first and second ice molds.
9. The icemaker appliance of claim 1 , further comprising a supply conduit and a supply valve, the supply conduit connectable to an external liquid supply, the supply valve connected to the supply conduit to regulate a liquid flow through the supply conduit into the icemaker appliance.
10. The icemaker appliance of claim 9 , wherein the supply conduit is in fluid communication with the first reservoir such that the liquid flow from the external liquid supply is supplied to the first reservoir.
