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).

Provided is a heating device and a refrigerator. The heating device includes a cylinder body provided with a pick-and-place opening, a door body configured to open and close the pick-and-place opening, an electromagnetic generating module configured to generate an electromagnetic wave signal, and a radiating antenna. The radiating antenna is configured to be electrically connected with the electromagnetic generating module to generate electromagnetic waves of a corresponding frequency according to the electromagnetic wave signal. The heating device further includes a signal processing and measurement and control circuit for measurement and control processing of the electromagnetic wave signal. The signal processing and measurement and control circuit is configured to be electrically connected with the electromagnetic generating module and is disposed at a rear lower part in the cylinder body, which not only can make the cylinder body have a relatively large storage space, but also can avoid the damage to the circuit due to excessively high food when a storage drawer is used for holding food.

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.
