Abstract
A microwave activated heating element for exposure to high energy microwaves to heat the element includes a water saturated cellular core, water, heat and flame resistant rubber coated with high temperature lubricant, and a wax center core to absorb and store heat from the microwave heated water and rubber. The construction of the heating element may be accomplished in several forms such as concentrically wound, tubular, layered, and sectioned in particles, to conform to the specific design and use of the outer appliance.
Claims14
A microwave activated heating element comprising:
- an outer structure affording a housing and accommodating the passage of high frequency microwaves;
- a flexible cellular core for receiving and suspending water in a cooled or heated state while allowing the passage of high frequency microwaves, said core being dimensioned for reception within said housing and for distribution of the water such that the water may thoroughly saturate and lie suspended in the cellular core to receive high frequency microwave energy whereby the rapid buildup of water temperature is effected;
- and
- a heat and flame resistant flexible rubber element having a predetermined thickness and conformal with the water saturated cellular core to facilitate the reception of high frequency microwave energy.
