Abstract

A downspout for delivering water to an ice tray in a refrigerated appliance includes a cavity defined by at least one flute and at least one lobe. The downspout includes an inlet port for receiving water. The at least one flute and at least one lobe are configured to create a substantially laminar flow of the water received from the inlet port along the at least one flute and the at least one lobe.

First claim

What is claimed is:

1. A downspout for delivering water to an ice tray in a refrigerated appliance comprising:
a cavity defined by at least one flute and at least one lobe; and
an inlet port for receiving water, wherein the at least one flute and at least one lobe are configured to create a substantially laminar flow of the water received from the inlet port along the at least one flute and the at least one lobe, wherein the downspout includes a water ingress portion proximate the inlet port and a water egress portion that is configured to be positionable proximate the ice tray, wherein the cavity includes a first cross-sectional area at the water ingress portion and a second cross-sectional area at the water egress portion, wherein the first cross-sectional area is smaller than the second cross-sectional area, wherein the first cross-sectional area comprises a first generally quatrefoil shape, and wherein the second cross-sectional area comprises a second generally quatrefoil shape.

2. The downspout of claim 1 , wherein the at least one flute and the at least one lobe include four flutes and four lobes, respectively, that define the first generally quatrefoil shape and the second generally quatrefoil shape of the cavity.

3. The downspout of claim 2 , wherein a first distance between opposing flutes defines a first diameter, wherein a second distance between opposing lobes defines a second diameter, and wherein the second diameter is greater than the first diameter.

4. The downspout of claim 2 , further comprising:
a water delivery member coupled to the inlet port, wherein the water delivery member is configured to direct a stream of water from the inlet port to a surface of the cavity.

5. The downspout of claim 4 , wherein the surface of the cavity is opposed to the inlet port.

6. A water delivery system for an ice tray of a refrigerated appliance comprising:
a downspout including:
a cavity defined by:
two or more elongated protuberances arranged substantially longitudinally along the cavity; and
two or more elongated grooves arranged substantially longitudinally along the cavity;

an inlet port;
an outlet positionable above the ice tray; and

a water delivery member coupled to the inlet port of the downspout.

7. The water delivery system of claim 6 , wherein the two or more elongated protuberances and the two or more elongated grooves include opposing elongated protuberances interspersed by opposing elongated grooves.

8. The water delivery system of claim 7 , wherein the water delivery member comprises:
a first end coupled to a water source;
a second end coupled to the inlet port; and
an inlet segment coupled to the inlet port and extending away from the downspout.

9. The water delivery system of claim 8 , wherein the inlet segment is positionable to deliver an inlet stream and a first portion of a downspout stream through the inlet port and into the cavity in a lateral direction towards a first contact area disposed on a wall of the cavity.

10. The water delivery system of claim 9 , wherein a second contact area is disposed on the wall of the cavity and between the first contact area and an outlet, wherein the second contact area is disposed over at least part of the two or more elongated protuberances and the two or more elongated grooves, and wherein the second contact area is configured to facilitate a substantially laminar flow of water between the first contact area and the outlet.

11. The water delivery system of claim 10 , wherein the inlet segment is substantially transverse to the downspout.

12. A water delivery system for a refrigerated appliance, comprising:
an elongated downspout including:
a hollowed-out portion defined by one or more lobes and one or more flutes arranged in an alternating lobe and flute configuration along a surface of the hollowed-out portion, wherein the one or more lobes and the one or more flutes are longitudinally disposed in a direction of the elongated downspout, wherein the alternating lobe and flute configuration includes a first cross-sectional area having a generally quatrefoil shape and a second cross-sectional area having a generally quatrefoil shape;

a fill line including:
a first end coupled to a water source and a second end coupled to the elongated downspout; and
an inlet segment coupled to the downspout and the fill line and extending toward the first end of the fill line, wherein the inlet segment includes multiple cross-sectional variances along a length of a channel.

13. The water delivery system of claim 12 , wherein the inlet segment includes a first interior dimension and a second interior dimension and wherein the second interior dimension is less than the first interior dimension.

14. The water delivery system of claim 13 , wherein the inlet segment and the downspout are a single part and wherein the inlet segment is positioned to direct water to a first contact area disposed on a surface of the hollowed-out portion of the downspout such that the water forms a substantially laminar flow along the one or more lobes and the one or more flutes.

15. The water delivery system of claim 12 , wherein the inlet segment engages the hollowed-out portion at a lobe of the one or more lobes.
