Abstract: An electric range is provided. The electric range may include a case; at least one heating unit configured to heat an object; at least one drive circuit configured to drive the heating unit; at least one display configured to display visual information; at least one air blowing fan configured to output air; and at least one air guide configured to guide air output from the air blowing fan to the drive circuit. The air output from the air blowing fan may be supplied to a first end of the air guide, and a height of an upper surface of the first end of the air guide may be greater than a height of an upper surface of the air blowing fan. A first portion of the air output from the air blowing fan may be discharged through a gap between the upper surface of the first end of the air guide and the upper surface of the air blowing fan, and supplied to the display.

Abstract: A switch device and a cooking device having a switch device. The switch device may include a first switch configured to be opened or closed based on contact or non-contact between the first blade and the second blade; a second switch configured to be opened and closed based on contact or non-contact between the third blade and the fourth blade; a housing that accommodates the first switch and the second switch therein; and an actuator disposed in the housing and actuated to selectively open and close the first switch and the second switch. The first switch and the second switch may be fixedly supported by a support structure disposed on a same plane as a mounting plane for the actuator and may be positioned in a single inner space.

Abstract: An electric range is provided that may include an elastic holder to fix a fuse and a sensor in a central portion of an induction heating unit disposed over/on/in an upper portion of a base plate, thereby stably fixing the fuse and sensor against external impact. In the electric range, an upper end of the sensor may come into close contact with a lower surface of a cover plate disposed over/on/in an upper portion of the induction heating unit, thereby stably measuring a temperature of the cover plate and absorbing an external impact.

Abstract: A cooking appliance is disclosed. The cooking appliance includes an electric heater for heating an object to be cooked, a mechanical manipulation unit connected to the electric heater for allowing a user to input primary ON/OFF of the electric heater and power of the electric heater, a normal open type DC relay connected to the manipulation unit, and a controller for controlling the DC relay to control secondary ON/OFF of the electric heater based on sensing of a primary ON state of the electric heater by the manipulation unit (a state in which the manipulation unit is operated).
