Claim of US Patent No. 10,655,270

1. A treating apparatus for drying articles according to a predetermined cycle of operation, comprising:a cylindrical drum having a circumferential wall;
a baffle on the circumferential wall comprising an anode element having an anode contact point at the circumferential wall;
a cathode element about the wall circumferentially spaced from the anode element along the circumference of the circumferential wall such that the entire cathode element is radially off-set from the anode element, the cathode element having a cathode contact point at the circumferential wall;
a capacitive coupling between the anode element and the cathode element; and
a radio frequency (RF) generator coupled to the anode element at the anode contact point and to the cathode element at the cathode contact point and selectively energizable to generate electromagnetic radiation in a radio frequency spectrum;
wherein energization of the RF generator sends electromagnetic radiation through the treating apparatus via the capacitive coupling to form a field of electromagnetic radiation (e-field) in the radio frequency spectrum to dielectrically heat liquid within articles disposed within the e-field.
