Thermoelectric icemaker and control
a technology of thermoelectric icemaker and control panel, which is applied in the field of refrigerators, can solve the problems of difficult and unpractical movement of ice upward from the bottom freezer compartment to the door of the fresh food compartment, and the temperature in the fresh food compartment is generally not sufficiently cold, so as to enhance the movement of the freezer air, enhance the heat transfer surface, and enhance the effect of heat transfer surfa

Benefits of technology
[0009]In another aspect, an ice mold having an enhanced heat transfer surface and located in a fresh food compartment of a bottom mount refrigerator is provided. The refrigerator comprises a freezer compartment comprising a freezer door, and a fresh food compartment located over the freezer compartment and comprising a fresh food door. The fresh food door comprises an ice dispenser. An ice maker is located in the fresh food compartment, and the ice maker comprises the ice mold with the enhanced heat transfer surface. A freezer air duct extends from the freezer compartment to the ice mold, and an air flow control device is provided for controlling flow of freezer air through the freezer air duct. A fan is located near the ice mold and the fan augments the movement of the freezer air.
Problems solved by technology
Specifically, the temperature in the fresh food compartment generally is not sufficiently cold to freeze items or to form ice.
Due to the location of the freezer (i.e., below the fresh food compartment), moving ice upward from the bottom freezer compartment to the door of the fresh food compartment would be difficult and not very practical.
Also, since the fresh food compartment temperature is above the freezing point, ice cannot be made in the fresh food compartment.

Embodiment Construction
[0014]Icemakers are utilized in residential, or domestic, refrigerators as well as in stand alone freezers. Users generally find it convenient to have ice dispensed through the refrigerator door. Such convenience can be readily provided with side-by-side and top mount refrigerator types. However, with bottom mount refrigerator types, moving ice formed in the freezer compartment upward to be dispensed through the fresh food compartment door is difficult, as well as not practical, in many, if not all, circumstances.
[0015]Set forth below is a description of an icemaker configuration that enables dispensing ice through the fresh food compartment door of a bottom mount refrigerator. In one specific embodiment, a thermoelectric device is used to make ice in the fresh food compartment. Thermoelectric icemakers are well known and commercially available. In the one specific embodiment, a freezer air duct extends from the freezer compartment and into the fresh food compartment, and a small st...

In one aspect, an icemaker for making ice in a fresh food compartment of a bottom mount refrigerator is provided. The refrigerator comprises a freezer compartment comprising a freezer door, and a fresh food compartment located over the freezer compartment and comprising a fresh food door. The fresh food door comprises an ice dispenser. An ice maker is located in the fresh food compartment, and the ice maker comprises an ice mold, and a thermoelectric device for moving heat from the ice mold. The mold is positioned so that ice from the mold can be dispensed by the ice dispenser in the fresh food door.

RELATED REISSUE APPLICATIONS[0001]More than one reissue application has been filed for the reissue of U.S. Pat. No. 6,735,959. The reissue applications are the initial reissue application Ser. No. 11 / 437,003 filed May 18, 2006 and a continuation reissue application Ser. No. 13 / 762,150, filed Feb. 7, 2003.CROSS-REFERENCE TO RELATED APPLICATION[0002]This application is a continuation reissue of application Ser. No. 11 / 437,003, filed May 18, 2006, which is an application for reissue of U.S. Pat. No. 6,735,959.BACKGROUND OF INVENTION[0003]This invention relates generally to refrigerators and more particularly, to icemakers for bottom mount freezer type refrigerators.[0004]Refrigerators and freezers typically include an icemaker. The icemaker receives water for ice production from a water valve typically mounted to an exterior of the refrigerator or freezer case. The water valve typically is coupled to a fill tube via polyethylene tubing. Water is dispensed from the fill tube into a tray...
