Abstract
Abstract A deep fat frying cooking system includes a solid state deep fat frying cooking timing control computer directly within the cooker console. The heat sensitive computer circuitry is positioned within a dead air compartment located behind the front panel of the cooker console aiding convenience of operation. The timing control computer is provided as a modular unit which may be easily mounted in the panel and conveniently removed for necessary replacement and/or repair.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
190 words
In a deep fat fryer cooking system including a deep fat frying kettle and heating means for heating the same, a housing substantially enclosing the bottom and four sides of the kettle and having a panel in proximity to a side of the kettle, the panel carrying kettle on-off and temperature controls and the like, the improvement of a heat sensitive solid state electrical circuitry deep fat frying cooking timing control computer module located in the panel, comprising: a chamber defined essentially by the frying kettle, the panel and the housing, the chamber being adapted to provide convection air flow for cooling of the frying kettle, a thermally insulated compartment within the chamber, the compartment being sealed from communiation with the chamber so as to define a dead air space therein, the temperature of the air within the chamber being above that temperature having a deleterious effect on the solid state electrical components of the computer, the temperature of the air within the compartment being below that temperature having a deleterious effect on the solid state electrical components of the computer, and the computer module being positioned within the compartment.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
69 words
The improvement as claimed in claim 1 wherein: one wall of the compartment is formed by the panel, the other walls defining the compartment are positioned within the chamber, and the computer module is mounted in the panel and the compartment maintained spaced from the walls of the compartment positioned within the chamber so as to minimize the likelihood of conduction heat flow to the module from the chamber.
Claim 4
Dependent Claim
48 words
The improvement as claimed in claim 2 wherein: a sensing probe means for sensing the characteristics of the frying oil is connected to the computer module, and the probe means is inserted in the wall of the frying kettle most proximate to the compartment containing the computer module.
Claim 5
Dependent Claim
41 words
The improvement as claimed in claim 2 wherein: the heat sensitive solid state components of the computer are located on a board-like support means, and the support means is positioned within the computer module spaced from the walls of the module.
