摘要:
A household appliance (1) e.g a washer-dryer, comprises an enclosure (2) into which objects to be heated are placed, a magnetron (4) for generating microwaves, a waveguide (3) for feeding the generated microwave into the enclosure, an arc detector (5) coupled to the waveguide (3) for detecting the arcing within the enclosure (2) and a control unit (6).

A combination closed-circuit washer and drier apparatus (11) having a washing cycle and a drying cycle. The apparatus comprises a unitary housing having a tub (37) and a tumbler (39) within the tub, the tub also having an air inlet (27) and air outlet (29) which allows air to flow through the tub, wherein air flowing from the air inlet is in communication with the tumbler. The apparatus also includes a desiccant recharging system (13) located within the unitary housing having a entrance (15c) and an exit (65), the entrance coupled to the tub air outlet and the exit coupled to the tub air inlet, thus allowing a continuous flow of air through the system. The desiccant recharging system also includes a diverting valve (17) that directs the flow of air primarily through the desiccant system in a closed-loop during the wash cycle. The diverting valve alters the air flow between the washing cycle, for desiccant regeneration, to the drying cycle, for desiccant water adsorption.

A radio frequency (RF) laundry dryer (10) includes, amongst other things, an RF generator (20), a drying surface (22), and a Faraday cage (26) enclosing the drying surface (22). The drying surface (22) on which textiles are supported further includes an RF applicator (12) having an anode (14) and cathode (16) coupled to the RF generator (20). At least a portion of the cathode (16) substantially encompasses the anode (14) to electrically shield the anode (14) from the Faraday cage (26) ensuring the formation of an e-field between the anode (14) and cathode (16) instead of the anode (14) and the Faraday cage (26) upon energizing the RF generator (20).

A method for heating a medium that includes an object having a variable weight is provided. The method comprises (A) placing medium including an object having variable weight into a variable enclosure having adjustable dimensions; (B) initiating a heating process by subjecting the medium including the object to a variable AC electrical field; (C) substantially continuously measuring an impedance of medium including the object during the heating process; (D) adjusting dimensions of said variable enclosure to optimize the heating process; (E) adjusting parameters of the variable AC electrical field to optimize the heating process; and (F) controlling the heating process.

A radio frequency (RF) laundry dryer (10) includes, amongst other things, an RF generator (20), an RF applicator (12) having a perforated body (18) supporting anode and cathode elements (14, 16), a fan (22) arranged relative to the perforated body (18) to flow or draw air through the perforated body (18), and an electromagnetic shield (26) protecting the fan (22) from the e-field. Both anode and cathode elements (14, 16) are operably coupled to the RF generator (20) to generate a field of electromagnetic radiation (e-field) between the anode and cathode upon the energizing of the RF generator (20).
