A heat treatment apparatus is configured to perform a heat treatment on a workpiece while rotating the workpiece. The heat treatment apparatus includes a rotary shaft configured to support the workpiece and on which a discharge nozzle is provided to spray cooling liquid toward the workpiece, a fixing base having a supply port and a discharge port for the cooling liquid, a coupling section coupling the fixing base and the rotary shaft to each other in a relatively rotatable manner, and a detector configured to detect a flow of the cooling liquid discharged from the discharge port. A supply passage and a discharge passage are formed inside the fixing base, the rotary shaft and the coupling section. The supply passage extends from the supply port and to the discharge nozzle. The discharge passage branches from the supply passage inside the rotary shaft and leads to the discharge port.

The present invention relates to a laundry care apparatus in which an induction module heats the drum uniformly using a magnetic field to dry laundry or heat wash-water, and center and front and rear regions of the drum are uniformly heated.

A laundry treatment apparatus is disclosed. The laundry treatment apparatus includes a cabinet, a tub arranged in the cabinet, a drum arranged in the tub and formed of a metal material, and an induction module configured to inductively heat the drum, wherein the induction module includes a coil formed by winding a wire, and a base housing including a base body arranged on the tub, and a fixing rib arranged on the base body to fix coil, wherein the wire is drawn into the base body in one direction, wound around the fixing rib, and drawn out of the base body in the same direction.

An anti-ice arrangement for a gas turbine engine may comprise an engine static structure, a fan blade housed for rotation within the engine static structure, and a magnetic field source mounted in close proximity to the fan blade and configured for inducing eddy currents in the fan blade to increase a surface temperature of the fan blade.

A cooking appliance apparatus includes at least one fan unit having at least one fan wheel which is mounted for rotation about a rotation axis. A heating element is provided to heat the fan wheel in at least one operating state, with the heating element being configured as an induction heating element.

An electromagnetic induction heating or cooling system including a housing having a fluid air inlet, a sleeve shaped support extending within the housing and including a plurality of spaced apart and radially extending magnetic or electromagnetic plates communicated with the inlet. An elongated conductive component is rotatably supported about the sleeve support and includes linearly spaced apart and radially projecting conductive plates which alternate with the spacing established by the magnetic or electromagnetic plates. A motor rotates the conductive component which, upon rotation of the conductive plates, generates magnetic fields to condition the fluid according to either of induction heating or cooling. The rotating plates of the conductive component are further individually configured so that they simultaneously redirect the conditioned fluid flow through a warm air outlet of the housing.

Disclosed is a laundry treatment apparatus configured to directly heat a drum containing laundry therein.
