Abstract

A heater for cups and fluids therein having an adjustable heat selector, heating circuitry and temperature stabilization circuitry, comprising a base support, an electrical circuit enclosing housing, an opening in an upper substantially horizontal surface of the housing for a heating element plate and heat sensor, and an upright section of the housing enclosing additional circuitry having a vertical, substantially cylindrical surface facing the heating element plate, substantially rectangular vertical surfaces for the remaining three sides of the upright section, the vertical substantially cylindrical surface and the substantially rectangular vertical surfaces forming an open-topped receptacle having inner partitions and a closed bottom for receiving assorted personal articles. The circuitry comprises a heat element, a solid-state controlled switch, a power supply, a temperature sensor, an adjustable temperature control and an integrated circuit having the basic functions of limiter, power supply, detector, sensing amplifier, gate and protection features.

Claims

1. A heater for cups and fluids therein, comprising:

a. adjustable heating circuitry means, said adjustable heating circuitry comprising a heating element and a solid-state controlled switch, AC power supply, temperature sensor;

adjustable temperature control and circuit and combined limiter, DC power supply, detector, sensing amplifier and gate and protection integrated circuitry in operative circuit therewith,

b. a base support,

c. a heating plate, said heating plate being disposed above said heating element and being comprised of heat-conductive material,

d. circuit-enclosing housing means, said circuit-enclosing housing means being supported by said base support and comprising a substantially horizontal surface defining an opening for mounting said heating plate therein and vertically-extending receptacle means, said vertically-extending receptacle means comprising a floor and front, rear and a pair of opposed side walls defining an open topped receptacle said front wall facing said heating element being concave about at least a portion of said heating plate, said floor being disposed at a level which is above the level of said horizontal surface,

f. said base support comprising a recess raised in an upwardly extending direction toward, and located substantially beneath, said heating element and said heating plate,

g. heating support means, said heating support means extending between said recess, said heating element and said heating plate and comprising a bolt,

h. said circuit-enclosing housing means being comprised of an electrically non-conductive material,

i. said solid-state controlled switch and said adjustable temperature control each being accessably located on an exposed portion of said circuit-enclosing housing means,

j. a sealed well, said sealed well being located in said heating plate,

k. said temperature sensor being located in said sealed well in thermal communication with a cup placed on said heating plate.
