Abstract
The invention relates to an improved frying pan providing good thermal contact between the pan bottom and the heating element, the device comprising a pan adapted with threaded studs to the underside thereof, a support plate adapted with a depression shaped to hold a heating element and further adapted with holes for engaging the support plate on the studs, whereby when locknuts are tightened onto the studs, all parts of the heating element are subject to compression.
Claims4
An improved electric frying pan comprising:
- a pan constructed of an aluminum core and a layer of stainless steel on each of the surfaces thereof and including a bottom and a continuous peripheral side wall upstanding from the bottom, and at least two threaded studs connected to the underside of said bottom in spaced relationship with each other;
- means, resistant to heat conduction, to support said pan in an elevated position;
- a plurality of washers and companion threaded lock nuts adapted to be received as a set on each of said studs;
- an electrically insulated heating element of a generally circular cross-section including a flat upper surface portion for contacting the bottom of said pan, said element adapted to be connected to an electrical source;
- a support plate defining a depression of depth less than the thickness of said heating element and into which said heating element will lie, a series of first holes for engagement over said studs and a plurality of second holes adjacent the centre of said plate for drainage of water that may become trapped above said support plate;
- in which by advancing said nuts onto said studs until said nuts are tight to the support plate, all parts of said heating element are subject to a compressive load.
