Abstract
Disclosed are a heating device () and a refrigerator. The heating device () includes a cylinder body (), a door body (), an electromagnetic generating module () and a radiating antenna (). A heating chamber () having a pick-and-place opening is defined in the cylinder body (), and the heating chamber () is configured to place an object to be processed. The door body () is disposed at the pick-and-place opening and configured to open and close the pick-and-place opening. The electromagnetic generating module () is configured to generate an electromagnetic wave signal. The radiating antenna () is disposed in the cylinder body () and electrically connected with the electromagnetic generating module () to generate electromagnetic waves of a corresponding frequency according to the electromagnetic wave signal. Since the peripheral edge of the radiating antenna () is formed by smooth curves, the distribution area of the electromagnetic waves in a plane parallel to the radiating antenna () may be increased, and the electromagnetic waves may be prevented from being too concentrated, thereby avoiding the problems of local overheating and uneven temperature of food.
