Electric range of which heat power is controlled without user intervention, and control method therefor

An electric range, comprising:

• a case;
• a cover plate coupled to an upper end of the case and having an upper surface on which a heating target is disposed;
• a heating portion disposed inside the case and configured to heat the heating target;
• and
• a controller configured to control the heating portion, wherein the controller controls the heating portion to reduce a heating power of the heating portion, when the heating target to be heated by the heating portion is lifted from the upper surface of the cover plate, wherein the controller controls the heating portion to reduce the heating power of the heating portion based on a height of the lifted heating target, and wherein the controller controls the heating portion for the height of the lifted heating target and a decrease value of the heating power to be proportional to each other.

• a cover plate coupled to an upper end of the case and having an upper surface on which a heating target is disposed;
• a heating portion disposed inside the case and configured to heat the heating target;
• and
• a controller configured to control the heating portion, wherein the controller controls the heating portion to reduce a heating power of the heating portion, when the heating target to be heated by the heating portion is lifted from the upper surface of the cover plate, wherein the controller controls the heating portion to reduce the heating power generated by the heating portion based on a time value for which the heating target is lifted, wherein the controller controls the heating portion for the time value for which the heating target is lifted and a decrease amount of the heating power to be proportional to each other, wherein when a first heating power is greater than or equal to a first critical heating power, the controller controls the heating portion to reduce the heating power by a first unit decrease amount in a section between the first heating power and the first critical heating power, and controls the heating portion to reduce the heating power by a second unit decrease amount in a section less than the first critical heating power, and wherein the first unit decrease amount is greater than the second unit decrease amount.
