Layering of low thermal conductive material on metal tray

摘要

An ice maker having a housing defining an interior volume, with an ice tray rotatably coupled with the housing and horizontally suspended across the interior volume thereof. The ice tray has ice wells, defined along the bottom by a bottom surface and the sides by an interior surface of at least one containment wall, wherein the containment wall has an upper portion, including a top surface of the containment wall and the interior surface adjacent the top surface. The upper portion of the containment wall has an insulating layer applied thereto. A tray for use in the ice maker and method of manufacturing the tray are also provided.

1. An ice forming tray for making clear ice, comprising:
an ice well, defined along its bottom by a bottom surface and upwardly from the bottom surface by at least one wall extending upwardly from the bottom surface, wherein the bottom surface and the at least one wall comprise a conductive material; wherein the at least one wall comprises an interior surface which is facing the ice well, a top surface which is generally opposite the bottom surface and which faces generally perpendicular to the interior surface, and an upper portion, comprising the top surface and a portion of the interior surface adjacent thereto; and an insulating layer applied only to the upper portion and the portion of the interior surface adjacent to the interior surface of the at least one wall.
