Abstract: A ventilation apparatus according to the present invention comprises: a case having a flow hole; a flow guide positioned inside the case, the flow guide having an inflow opening that communicates with the flow hole, and the flow guide having a guide surface that slopes downward as the same extends outward; a swirler positioned in an area formed by the flow guide and configured to rotate in order to discharge a part of air introduced through the flow hole out of the case again, the swirler having a plurality of blades; a driving motor for rotating the swirler; and a grill member that covers the swirler outside the case and provides an air channel. The grill member comprises a grill rib that forms a suction channel for suctioning air and a discharge channel for discharging air. The discharge channel may be positioned outside the suction channel.

Abstract: An induction heating type cooktop includes a cover plate, a working coil, a thin film, an additional metal film, and an insulator. The cover plate is coupled to a top of a case and includes an upper plate configured to place an object to be heated. The working coil is disposed in the case and configured to heat the object. The thin film is disposed on the upper plate. The additional metal film forms an equivalent circuit with the thin film and the object so as to allow an induced current by the working coil to be induced into the object arranged at the upper plate. The insulator is disposed between a bottom surface of the upper plate and the working coil.
