Refrigerator with temperature control

摘要

An insulated icemaking compartment is provided in the fresh food compartment of a bottom mount refrigerator. The icemaking compartment may be integrally formed with the liner of the fresh food compartment, or alternatively, may be modular for installation anywhere in the fresh food compartment. A removable bin assembly with a front cover normally seals the icemaking compartment to maintain the temperature in the compartment. A cold air duct formed in the rear wall of the refrigerator supplies cold air from the freezer compartment to the icemaking compartment. A return air duct directs a portion of the air from the icemaking compartment back to the freezer compartment. An air vent in the icemaking compartment directs another portion of air into the fresh food compartment. A control system provides for controlling refrigerator functions in a manner that promotes energy efficiency.

主权项

1. A refrigerator comprising:
a refrigerator cabinet; a fresh food compartment disposed within the cabinet; a freezer compartment disposed within the cabinet; an ice compartment disposed within and at an upper corner of the cabinet; an electronic control system associated with the refrigerator and adapted to monitor and control temperature in the fresh food compartment, the freezer compartment and the ice compartment; an ice compartment temperature sensor associated with the ice compartment and electrically connected to the electronic control system; a fresh food compartment temperature sensor associated with the fresh food compartment and electrically connected to the electronic control system; a freezer compartment temperature sensor associated with the freezer compartment and electrically connected to the electronic control system; an ambient temperature sensor electrically connected to the electronic control system; and wherein the electronic control system includes a microprocessor that performs a subroutine comprising calculating control temperature values and regressed temperature values for at least one of the fresh food compartment, the freezer compartment, and the ice compartment based, at least in part, on temperature readings from at least one of the ice compartment sensor, the fresh food compartment sensor, and the freezer compartment sensor.
