Abstract
An electric fry pan in which the pan is formed from cast iron to the underside of which a heat sink of aluminium is secured by mechanical means, the heat sink making close physical contact with a major portion of the underside of the pan. The electric heater element is associated with the heat sink and has connected to it an electrical connector by means of which the heater element may be connected to an electricity supply.
Claims6
An electric fry pan, comprising an electric heating element connectable with an electric source and having a predetermined configuration;
- a heat distributing element constituted of aluminum and being in contact with said heating element so as to be heated by the latter;
- and a pan having an underside with a major portion which is in contact with said heat distributing element so that heat is transmitted from the latter to and distributed over said pan, means for securing said aluminum heat distributing element to said underside of said pan, said electric heating element being secured to said heat distributing element, said electric heating element being electrically insulated from said heat distributing element and said pan, and electric connecting means arranged to connect said electric heating element with the electric source and being electrically insulated from said heat distributing element and said pan, said pan having a bottom wall and side walls constituted of cast iron having high heat capacity and low thermal conductivity, so as to provide for a large heat reservoir ensuring good culinary properties and at the same time to avoid a localization of heat in said pan in the regions corresponding to the configuration of said electric heating element.
