Hand-held mixing device with heating element

A hand-held mixing device comprising:

• a first upper housing section;
• a second upper housing section attachable to said first upper housing section;
• an electric motor disposed between said upper housing sections;
• a generally tubular lower housing section having an open upper end and an open lower end, said lower housing section being attachable to said first and second upper housing sections;
• an elongated shaft extending through said lower housing section connected to said motor;
• a blade at the free end of said shaft;
• a heating element;
• mounting means for mounting said shaft and said heating element to said open lower end of said lower housing section with said blade and said heating element extending therefrom, said mounting means forming a fluid-tight seal between said lower housing section and said shaft and between said lower housing section and said heating element wherein said lower housing section is immersible in fluids;
• and
• circuit means connectable to an electrical power source for controlling said heating element and said motor, said circuit means including switch means for independently varying the speed of said motor and the temperature of said heating element.

A hand-held mixing device comprised of an upper assembly and a lower assembly, said lower assembly including:

• a lower housing section;
• a shaft having a motor end and a free end;
• a blade at the free end of said shaft;
• first circuit means including a heating element;
• means for mounting said shaft and said heating element to said lower housing section to form a fluid-tight assembly with said blade and said heating element being external to said lower housing section, said upper assembly including:
• first and second housing sections;
• second circuit means within said first and second housing sections connectable to said first circuit means;
• said second circuit means being connectable to an external power source and including a motor, motor switch means having multiple switch settings establishing multiple motor operating conditions, heating element switch means having multiple switch settings establishing multiple heating element operating conditions, and actuator switch means enabling said heating element and said motor.
