Abstract
A dishwasher with a dry mode having a wash compartment and a heating unit. The heating unit is used to directly heat fan blades of a fan from outside the wash compartment. The heating unit further includes a fan motor, multiple fan blades, and a wireless power source. The fan motor drives the fan blades. The fan blades are made up of a ferromagnetic material which are fluidly coupled with an atmosphere of the wash compartment. The wireless power source wirelessly induces heating of the ferromagnetic material while the fan blades circulate the atmosphere, and the ferromagnetic material heats the atmosphere of the wash compartment.
