Electric deep fat fryer with controlled heat during start-up

Claim 2

A fat-melting electric deep-fat fryer having low-high heating modes for fat melt and fat fry operations comprising an upstanding body having a receptacle opening to the top thereof; a control panel mounted on the fryer body; baskets for containing the food product to be fried hanging from means supported on the upper edge of the said receptacle; a power circuit comprising first, second and third heating elements traversing across and adjacent to the bottom of the receptacle in side-by-side relation and electrically connected to 220-volt A.C. three-phase electrical power supply mounted on a terminal block; a heating control circuit comprising two-way switch means mounted on the control panel for switchover of the heating elements of the power circuit from series circuit hook-up for the melt operation to parallel circuit hook-up of the same for fry operation; first, second and third relay-actuated switches for each of the first, second and third legs of the delta hook-up electrically connected to the said two-way switch means for switchover of the power circuit from series-circuit heating element hook-up for the fat melt operation to parallel circuit hook-up for the fat fry operation; and a main thermostat operatively connected in the circuit along with the two-way switch means between the power supply and the first, second and third relay-actuated switches for regulating the temperature of the fat in the fryer receptacle during fry operation.

Claim 3

A fat-melting electric deep-fat fryer having low and high heating modes for fat melt and fat fry operations comprising an upstanding body including a deep fat receptacle opening to the top of said body; a control panel mounted on the fryer body and having indicating lights displayed on the face thereof; baskets for containing the food product to be fried hanging from means supported on the upper edge of the receptacle; first, second and third heating elements comprising a heating power circuit traversing across and adjacent to the bottom of the vessel in side-by-side relation and electrically connected to 220-volt A.C. three-phase electrical power supply mounted on a terminal block; a heating control circuit comprising a thermostatic-controlled two-way switch mounted on the control panel for automatic switchover of heating elements of the power circuit from series circuit hook-up for melt operation to parallel circuit hook-up of the same for fry operation when all the fat in the fryer has melted; first, second and third relay-actuated switches for each of the first, second and third legs of the delta hook-up electrically connected to the thermostatic-controlled fry-melt two-way switch for automatic switchover of the power circuit from series-circuit heating element hook-up for the melt operation to parallel circuit hook-up for the fry operation when the temperature reaches a level indicating all the fat has melted, and a main thermostat operatively connected in the circuit along with the thermostatic-controlled two-way switch between the power supply and the first, second and third relay-actuated switches for regulating the temperature of the fat in the fryer receptacle during fry operation.

Claim 4

A fat-melting electric deep-fat fryer having low and high heating modes for fat melt and fat fry operations comprising an upstanding body including a deep fat receptacle opening to the top of said body; a control panel mounted on the fryer body and having indicating lights displayed on the face thereof; baskets for containing the food product to be fried hanging from means supported on the upper edge of the receptacle; first, second and third heating elements comprising a heating power circuit traversing across and adjacent to the bottom of the vessel in side-by-side relation and electrically connected to 220-volt A.C. three-phase electrical power supply mounted on a terminal block; a heating control circuit comprising a thermostatic-controlled two-way switch mounted on the control panel for automatic switchover of heating elements of the power circuit from series circuit hook-up for melt operation to parallel circuit hook-up of the same for fry operation when all the fat in the fryer has melted; first, second and third relay-actuated switches for each of the first, second and third legs of the delta hook-up electrically connected to the thermostatic-controlled fry-melt two-way switch for automatic switchover of the power circuit from series-circuit heating element hook-up for the melt operation to parallel circuit hook-up for the fry operation when the temperature reaches a level indicating all the fat has melted, and a main thermostat operatively connected in the circuit along with the thermostatic-controlled two-way switch between the power supply and the first, second and third relay-actuated switches for regulating the temperature of the fat in the fryer receptacle during fry operation.
