Abstract
Abstract A system and Hot Cabinet server therefor to condition pre-packaged foods and to maintain them at serving temperature during storage and for customer access. A structural relationship of means is provided in cooperatively related bin type cabinets to combine the inherent principles of convection, conduction and recirculation to maximum advantage and to the end that heat loss is minimized despite the completely open and accessible bin configuration. The cabinets are each a self-sufficient entity when supplied with power such as an electrical plug in, and each is completely mobile while in operation; and being of the same height and width configuration, they are adapted to be quickly assembled in service lines that are readily modified or broken down for storage.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
106 words
A Hot Cabinet for conditioning pre-packaged foods and the like and to maintain the same at pre-determined temperature and including; a bin type cabinet body with insulated outer panels, an upwardly open well complementary to and depending into the body in spaced relation to the outer panels thereof forming a plenum therebetween, the bin type cabinet and complementary well being of rectangular three dimensional configuration, and air tempering means comprised of inlets at the upper peripheral corners of the well inducing air from the well and through temperature responsive heating means and vented to discharge the same through said plenum and into the well for recirculation.
Claim 2
Dependent Claim
106 words
A Hot Cabinet for conditioning pre-packaged foods and the like and to maintain the same at pre-determined temperature and including; a bin type cabinet body with insulated outer panels, an upwardly open well complementary to and depending into the body in spaced relation to the outer panels thereof forming a plenum therebetween, the bin type cabinet and complementary well being of rectangular three dimensional configuration, and air tempering means comprised of inlets at the upper peripheral corners of the well inducing air from the well and through temperature responsive heating means and vented to discharge the same through said plenum and into the well for recirculation.
Claim 3
Dependent Claim
43 words
The Hot Cabinet for conditioning and maintaining the temperature of prepackaged foods and the like as set forth in claim 1, wherein the complementary well is vented with downwardly disposed nozzles along its upper periphery for discharge of heated air into the well.
Claim 4
Dependent Claim
60 words
The Hot Cabinet for conditioning and maintaining the temperature of pre-packaged foods and the like as set forth in claim 1, wherein the complementary well is heat conductive for the absorption of heat from the heated air discharged through the plenum and is vented with downwardly disposed nozzles along its upper periphery for discharge of heated air into the well.
Claim 5
Dependent Claim
117 words
A Hot Cabinet for conditioning pre-packaged foods and the like and to maintain the same at a predetermined temperature and including; a bin type cabinet body of three dimensional rectangular configuration with corner related side and end and bottom panels, an upwardly open well complementary to and depending into the body in spaced relation to the side and end and bottom panels thereof and forming a plenum therebetween, there being a central opening through the said bottom panel, a temperature responsive heating means in open communication with the plenum through said central opening, and means inducing air from the corners of the well and discharging the same from the sides of the well and thereinto for recirculation.
Claim 6
Dependent Claim
