ABSTRACT:
A retractable temperature control for refrigeration units includes a control panel pivoted for movement between an extended, accessible position and a retracted position in which it is enclosed within one of the insulated walls of the unit. Mounted on the panel are two operators, one of which controls the temperature of a thermostat and the other of which controls the position of a damper. Adjustment of the operator associated with the thermostat controls the temperature of one compartment in the refrigeration unit and adjustment of the other operator controls the position of a damper, and in turn controls the differential temperature between the two compartments provided by the refrigeration unit. The thermostat and the damper control are structured so that movement of the control panel between the retracted and extended positions does not affect the adjustment thereof. When the controls are in the retracted position, they do not interfere with the placement of articles stored within the refrigeration compartments. Further, retraction of the controls prevents accidental damage of the controls and/or accidental change in the adjusted positions thereof.
