Abstract
A heat reduction volume compensator for use with a drip coffee maker in which the temperature applied by a hot plate to a coffee pot is reduced as the amount of liquid in the pot decreases by means of resilient segments that lift the pot away from the hot plate as the weight of the liquid in the coffee pot decreases.
Claims12
A heat reduction liquid volume compensator comprising:
- a body adapted to seat over a heat source and carry the weight of a fluid container,
- said body having a plurality of circumferentially spaced resilient segments, each said segment having an attached end and a free end,
- said body defining two oppositely facing contact surface portions disposed in substantially parallel spaced planes in an extended position, at least one of said planes being defined by said free ends, and
- said contact surface portions being movable in relation to each other, the spacing between said contact surface portions decreasing in response to the weight of said container, and the resilience of said segments causing said contact surface portions to return automatically to said extended position when said weight is removed, the resilience of the segments being sufficient to cause the spacing between said contact surface portions to increase sufficiently to result in a reduction of heat applied to said container by said heat source as the amount of liquid in said container is reduced.

A heat reduction liquid volume compensator for reducing the heat applied to a fluid container by a heat source as the fluid container is emptied of a contained quantity of heated liquid, said compensator comprising:
- a disk shaped body adapted to seat over said heat source and carry the weight of said fluid container,
- said body being formed with a plurality of circumferentially spaced resilient segments, each said segment having an attached end and a free end,
- said free ends being disposed a selected distance above a plane that includes said attached ends,
- said free ends being movable toward said plane in response to said weight being applied to said free ends, and
- said free ends supporting said fluid container with said segments being lowered to a position closer to said heat source under said weight and the resilience of said segments causing said fluid container to rise away from said heat source as said fluid container is emptied of said heated liquid a distance sufficient to result in the reduction of the heat applied to said container by said heat source.
