Filed:

Jul 13, 1999

Appl. No.:

09/351838

Inventors:

Timothy Worthington - Louisville KY
Steven J. Gray - Louisville KY
Douglas A. Able - Shelbyville KY

Assignee:

General Electric Company - Schenectady NY

International Classification:

H05B 102

US Classification:

219497, 219506, 219413, 219508, 99331

Abstract:

Apparatus and methods for controlling operation of an oven by differentiating between normal temperature cycling and an abnormal event in which the temperature drifts substantially below the lower band limit are described. Such differentiation enables use of differentiated modes to bring the oven temperature back to within a tolerance band or range. Particularly, and in connection with an oven including a microcomputer, a relatively low heat rate mode is used to maintain the oven temperature within the tolerance band or range, and a relatively high heat rate mode is utilized to return the oven temperature back to within the tolerance band or range quickly if the temperature drops below a lower set limit indicative of the occurrence of a drift event. The microcomputer is programmed so that after completion of preheating, the oven temperature is controlled by the user set temperature and offsets. Power cycling of the bake and broil heaters is controlled according to timing defined by prestored parameters.

Assignee:

General Electric Company - Schenectady NY

International Classification:

G01K 1300

US Classification:

62130, 62127, 374102

Abstract:

A system for displaying a temperature of a refrigerator compartment including at least one temperature sensor is provided that emulates the function and behavior of a thermostat to control and display refrigerator compartment temperature in a simple and intuitive manner. The system includes a controller including a processor and a memory and operatively coupled to the temperature sensor. A human machine interface board includes a display and is coupled to the controller and configured for receiving user input of a refrigerator compartment setting. The controller is configured to accept a set temperature of the at least one compartment, monitor actual temperature of the compartment; and display a damped temperature value based on operating conditions of the refrigerator.

International Classification:

F25D 1708

US Classification:

62 89, 62264, 62414

Abstract:

A refrigerator includes a vertically extending airflow distribution assembly for reducing vertical temperature gradients therein, and laterally extending air passages are in flow communication with the air distribution assembly for reducing horizontal temperature gradients therein. A single fan simultaneously directs freezer compartment air into the air distribution assembly, the laterally extending passages and into a storage drawer for temperature regulation therein. A damper is located in flow communication with a light assembly and is selectively positionable to cool the refrigeration compartment through the air distribution assembly and the laterally extending passages, as well as to remove heat from the light assembly that may damage a refrigeration compartment liner.

International Classification:

F25D 1704

US Classification:

62417, 62440, 62455, 62418, 62408

Abstract:

A refrigerator airflow distribution assembly includes an airflow diverter in flow communication with freezer compartment air. The diverter includes a primary flow path and at least one diverter opening therethrough, and together with a cover forms a secondary flow path in flow communication with the first flow path through the diverter opening. Freezer compartment air is directed to the primary flow path, and a portion of the air in the primary flow path flows through the diverter openings and into the secondary flow path, and is introduced to the fresh food compartment through one or more vents in the cover. Metered airflow through the diverter reduces temperature gradients in the refrigerator, as well as provides a regulated temperature source for a storage drawer in the fresh food storage compartment.
