Abstract

A inductively coupled beverage warmer for safely heating a beverage contained in a container. The inductively coupled beverage warmer includes a container having a bottom wall and a side wall; and also includes a temperature sensitive switch disposed in the container, a heater connected to the temperature sensitive switch, and a secondary induction coil connected to the resistor and disposed on the bottom wall of the container; and further includes a base member including a housing having a top wall, side walls, and an circular recessed portion in the top wall; and also includes a power cord extending through a hole in the housing and being connectable to a power source, an on/off switch mounted to the housing, a contact switch moveably disposed upwardly through an opening in the recessed portion, and a primary induction coil disposed under the recessed portion and connected to the contact switch for inducing electrical current in the secondary induction coil.

Claims

1. An inductively coupled beverage warmer comprising:

a container having a bottom wall, a beverage holding compartment, and being adapted for holding a beverage therein;

a means for heating a beverage contained in said container;

a base member including a housing having a top wall, side walls, and a centrally-disposed circular recessed portion in said top wall; and

a means for energizing said heating means;

wherein said means for heating a beverage includes a temperature sensitive switch disposed inside said container, a heater disposed inside said container and connected to said temperature sensitive switch, and a secondary induction coil disposed inside said container and connected to said heater.

2. An inductively coupled beverage warmer as described in claim 1, wherein said secondary induction coil is disposed upon said bottom wall of said container for heating a beverage contained in said container.

3. An inductively coupled beverage warmer as described in claim 1, wherein said means for heating a beverage may further include a means for grounding said secondary induction coil inside said container.

4. An inductively coupled beverage warmer as described in claim 1, wherein said means for energizing said heating means includes a power cord extending into said housing through an hole in a side wall thereof and being adapted for connecting to a power source, an on/off switch connected to said power cord and being disposed in and mounted to a side wall of said housing of said base member, a contact switch connected to said on/off switch and being moveably disposed in said housing and being in contactable relationship with said container when said container is placed upon said base member;

and a primary induction coil disposed in said housing and extending upwardly through an opening in said recessed portion of said top wall of said housing and being adapted for transferring electrical current to said secondary induction coil.

5. An inductively coupled beverage warmer comprising:

a container having a bottom wall, side wall, a handle member securely attached to said side wall, a beverage holding compartment, and being adapted for holding a beverage therein;

a means for heating a beverage contained in said container including a temperature sensitive switch disposed inside said container, a heater disposed inside said container and connected to said temperature sensitive switch, and a secondary induction coil disposed inside said container and connected to said heater, said secondary induction coil being disposed upon said bottom wall of said container for heating a beverage contained in said container, said means for heating a beverage capable of including a means for grounding said secondary induction coil inside said container;

a base member including a housing having a top wall, side walls, and a centrally-disposed circular recessed portion in said top wall said base member having a height of approximately 6 inches and a width of approximately 5 inches; and

a means for energizing said heating means including a power cord extending into said housing through an hole in a side wall thereof and being adapted for connecting to a power source, an on/off switch connected to said power cord and being disposed in and mounted to a side wall of said housing of said base member, a contact switch connected to said on/off switch and being moveably disposed in said housing and being in contactable relationship with said container when said container is placed upon said base member; and

a primary induction coil disposed in said housing and extending upwardly through an opening in said recessed portion of said top wall of said housing and being adapted for transferring electrical current to said secondary induction coil.

6. An inductively coupled beverage warmer comprising:

a container having a bottom wall, a beverage holding compartment, and being adapted for holding a beverage therein;

a means for heating a beverage contained in said container;

a base member including a housing having a top wall, side walls; and

a means for energizing said heating means;

wherein said means for heating a beverage includes a temperature sensitive switch disposed inside said container, a heater disposed inside said container and connected to said temperature sensitive switch, and a secondary induction coil disposed inside said container and connected to said heater.

7. An inductively coupled beverage warmer as described in claim 6, wherein said secondary induction coil is disposed upon said bottom wall of said container for heating a beverage contained in said container.

8. An inductively coupled beverage warmer as described in claim 6, wherein said means for heating a beverage may further include a means for grounding said secondary induction coil inside said container.

9. An inductively coupled beverage warmer as described in claim 6, wherein said base member has a recessed portion in said top wall, and said means for energizing said heating means includes a power cord extending into said housing through an hole in a side wall thereof and being adapted for connecting to a power source, an on/off switch connected to said power cord and being disposed in and mounted to a side wall of said housing of said base member, a contact switch connected to said on/off switch and being moveably disposed in said housing and being in contactable relationship with said container when said container is placed upon said base member;

and a primary induction coil disposed in said housing and extending upwardly through an opening in said recessed portion of said top wall of said housing and being adapted for transferring electrical current to said secondary induction coil.
