Abstract
A portable cooking installation consists of a heat-insulated enclosure containing a plurality of separately controllable electrical-resistance heating element surrounding and at least partially defining a space to receive a cooking vessel. For instance, two, three or four strip elements formed into circles of progressively increasing diameter (reckoning upwards) lie horizontally around a common axis to define a space to receive a suitably tapering cooking vessel; the elements can have aligned planar inner surfaces and be mounted on a resilient common support to improve vessel/element contact.
Claims2
A portable article of cooking equipment consisting of:
- an enclosure member, open at the top and comprising a surrounding wall formed of heat-insulating material and a base formed of heat-insulating material:
- a resilient support member within said enclosure member and having an internal wall portion defining an inner chamber open at the top and of decreasing cross-section from top to bottom, and a resilient support for said internal wall portion, said internal wall portion being spaced from said surrounding wall and from said base of said enclosure member;
- a plurality of strip electrical-resistance heating elements formed into a series of like loop-shaped members supported on the inner surface of said internal wall portion in a horizontal disposition and vertically spaced one from the other, thereby defining a space for receiving a cooking vessel resting by gravity against each element;
- resilient support means on said internal wall portion, said elements being mounted on said resilient support means to accommodate small deformations of fit between the elements and a cooking vessel held therein;
- electrical insulation means spacing said elements at least from said internal wall portion;
- separate electrically insulating electrical connections, one for each heating element;
- and electrical switching means mounted to the outer wall of said enclosure member and connected to said electrical connections, whereby said heating elements can be selectively controlled.
