Abstract
A microwave coffee maker includes a microwave generator for heating water. The heated water is discharged to a filtering vessel and then to a coffee container. The coffee container is mounted on a support plate on the underside of which is disposed a microwave absorbing material. That material is exposed to the microwaves and is heated thereby. The heat is conducted to the coffee container through the support plate to keep the coffee warm.
Claims9
A microwave coffee maker comprising:
- a heating chamber including a heating pipe for receiving and conducting water;
- microwave generating means for generating microwaves to heat water in said heating pipe;
- a siphon pipe connected to said heating pipe for siphoning the heated water to a water outlet situated outside of said heating chamber and isolated from microwaves generated by said microwave generating means;
- a coffee filtering vessel removably positionable beneath said water outlet for receiving water therefrom;
- a support plate disposed beneath said coffee filtering vessel and including an upper side for supporting thereon a coffee container to collect coffee from said coffee filtering vessel, said upper side situated outside of said heating chamber and being isolated from microwaves generated by said microwave generating means, said support plate including an underside situated beneath said upper side;
- and
- a microwave absorbing material disposed on said underside of said support plate and exposed to microwaves from said microwave generating means for being heated thereby and conducting heat to said upper side for keeping the coffee warm.

A microwave coffee maker comprising:
- a heating chamber;
- a microwave generator for directing microwaves into said heating chamber, said microwave generator including a magnetron and a transformer;
- a water conducting conduit including:
- an inlet end for connection with a supply of water to be heated,
- an outlet end for discharging heated water,
- a helically coiled heating section disposed between said inlet end and said outlet end and situated in said heating chamber, said heating section formed of a microwave permeable material so that water traveling therethrough is heated by microwaves in said heating chamber,
- a siphon section disposed between said heating section and said outlet end for siphoning the heated water to said outlet end, and
- a heat exchange section disposed between said inlet end and said heating section and arranged in heat exchanging relationship with said transformer and said magnetron for transferring heat from said transformer and said magnetron to water flowing through said heat exchange section;
- a coffee filtering vessel removably positionable beneath said outlet end for receiving heated water therefrom;
- a support plate disposed beneath said coffee filtering vessel and including an upper side for supporting thereon a coffee container to collect coffee from said coffee filtering vessel, said upper side situated outside of said heating chamber and isolated from microwaves therein, said support plate including an underside situated beneath said upper side;
- and
- a microwave absorbing material disposed on said underside of said support plate and exposed to microwaves for being heated thereby and conducting heat to said upper side for keeping the coffee warm.
