Disclosed is a heating device (100), including: a metal cylinder body (110) provided with a pick-and-place opening, a door body (120) configured to open and close the pick-and-place opening, an electromagnetic generating module (161) configured to generate an electromagnetic wave signal, and a radiating antenna (150). The radiating antenna (150) is configured to be electrically connected with the electromagnetic generating module (161) to generate electromagnetic waves of a corresponding frequency according to the electromagnetic wave signal. The heating device (100) further includes an antenna housing (130) made of an insulating material. The antenna housing (130) is configured to separate an inner space of the cylinder body (110) into a heating chamber (111) and an electrical appliance chamber (112), wherein an object to be processed and the radiating antenna (150) are respectively disposed in the heating chamber (111) and the electrical appliance chamber (112), and the radiating antenna (150) is configured to be fixedly connected with the antenna housing (130). The heating device (100) covers and fixes the radiating antenna (150) through the antenna housing (130), which not only can separate the object to be processed from the radiating antenna (150) to prevent the radiating antenna (150) from being dirty or damaged by accidental touch, but also can simplify the assembly process of the heating device (100) to facilitate the positioning and installation of the radiating antenna (150).

Disclosed are a heating device (100) and a refrigerator. The heating device (100) includes a cylinder body (110), a door body (120), an electromagnetic generating module (161) and a radiating antenna (150). A heating chamber (111) having a pick-and-place opening is defined in the cylinder body (110), and the heating chamber (111) is configured to place an object to be processed. The door body (120) is disposed at the pick-and-place opening and configured to open and close the pick-and-place opening. The electromagnetic generating module (161) is configured to generate an electromagnetic wave signal. The radiating antenna (150) is disposed in the cylinder body (110) and electrically connected with the electromagnetic generating module (161) to generate electromagnetic waves of a corresponding frequency according to the electromagnetic wave signal. Since the peripheral edge of the radiating antenna (150) is formed by smooth curves, the distribution area of the electromagnetic waves in a plane parallel to the radiating antenna (150) 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.

Disclosed is a heating device (100), including a cylinder body (110) provided with a pick-and-place opening, a door body (120) configured to open and close the pick-and-place opening, and an electromagnetic generating system. At least a part of the electromagnetic generating system is disposed in the cylinder body (110) or accessed into the cylinder body (110), so as to generate electromagnetic waves in the cylinder body (110) to heat an object to be processed. The heating device (100) further includes plastic components (130, 140) disposed on a propagation path of the electromagnetic waves. The plastic components (130, 140) are made of a non-transparent PP material to reduce the electromagnetic loss of the electromagnetic waves on the plastic components (130, 140) so as to indirectly increase the ratio of the electromagnetic waves acting on the object to be processed, thereby increasing the heating rate of the object to be processed.

Disclosed are a heating device and a refrigerator. The heating device includes: a cylinder body, in which a heating cavity is defined and configured to place an object to be processed; an electromagnetic generating module, configured to generate an electromagnetic wave signal; a radiating antenna, electrically connected with the electromagnetic generating module to generate electromagnetic waves of a corresponding frequency in the heating cavity according to the electromagnetic wave signal, so as to heat the object to be processed in the heating cavity; and a signal processing and measurement and control circuit, electrically connected with the electromagnetic generating module and disposed outside the cylinder body. In the heating device of the present invention, the signal processing and measurement and control circuit is disposed outside the cylinder body and does not occupy the space of the heating cavity inside the cylinder body, so that the size of the available space inside the heating cavity is greatly increased, thereby increasing the space utilization rate of the heating cavity. At the same time, the heat generated by the signal processing and measurement and control circuit during operation may be prevented from entering the heating cavity and being transferred to the object to be processed, thereby improving the heating uniformity.
