摘要： A thawing method for a heating apparatus, and the heating apparatus. The heating apparatus includes a cavity capacitor used for placement of an object to be treated, and an electromagnetic wave generation module that generates an electromagnetic wave signal used for heating the object to be treated. The thawing method includes: receiving a thawing instruction input by a user, acquiring a feature parameter that reflects the weight of the object to be treated, a power value of the electromagnetic wave signal, and a rate of change in a dielectric coefficient of the object to be treated; and determining the thawing progress of the object to be treated according to the feature parameter, the power value and the rate of change. The present invention is less influenced by the precision of a sensing device itself, and achieves relatively accurate determination of the thawing progress.

摘要： 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.

摘要： 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.

摘要： Provided 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, provided with a pick-and-place opening located on a front side of the cylinder body; a door body, configured to open and close the pick-and-place opening of the cylinder body; an electromagnetic heating device, configured to generate electromagnetic waves into the heating cavity to heat the object to be processed; and magnetic elements, disposed on the door body or the cylinder body and configured to enable the door body and the cylinder body to attract each other, so that when the door body is in a closed state in which the door body seals the pick-and-place opening, the door body and the cylinder body are in close electrical contact, thereby forming a continuously conductive shielding body. By disposing the magnetic elements, on the one hand, the size of a gap between the door body and the cylinder body is reduced, and the amount of electromagnetic leakage is reduced; and on the other hand, it facilitates the door body and the cylinder body forming a continuously conductive shielding body to prevent electromagnetic waves from being emitted through the gap that may exist between the door body and the cylinder body, thereby effectively shielding the electromagnetic radiation and eliminating the harm of the electromagnetic radiation to the human body.

摘要： 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.
