Abstract

A refrigerator principally for home use, the refrigerator having a temperature control panel on the front exterior thereof for indicating and regulating the temperatures within both the freezer and cool compartments, thus readily providing means for observing and controlling the existing temperatures therein, and eliminating the necessity of opening the refrigerator doors for ascertaining and adjusting internal refrigerator temperatures to efficient and desirable levels.

Claims

1. In a refrigerator incorporating exterior temperature control means, the combination of a refrigerator having a cool compartment and a freezer compartment, a front door for each said compartment, a control panel for each said compartment located on an exterior wall of said refrigerator, each said control panel including a fixed, temperature calibrated dial with rotatable knob having an attached indicating needle, constituting means to select and maintain a desired temperature level for its respective compartment in conjunction with a thermo electric mechanism, a temperature insulated space embodied in the refrigerator, convenient to the cool compartment and freezer compartment thereof, said space divided into two chambers, temperature insulated from each other, said chamber housing an externally controlled thermostatic element, each chamber having an air conduit, opening into its respective compartment.

2. The combination as set forth in claim 1 wherein a temperature guage is mounted on each said door, such guages being readable from exterior of the refrigerator and indicating the temperature inside each said compartment.

3. The combination set forth in claims 1 and 2 except comprising a refrigerator having a single compartment, either a freezer compartment of a cool compartment, with a single chamber, single control panel and its components, single thermo electric mechanism and temperature guage.
