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： A muffling device and refrigerating and freezing apparatus. The muffling device, comprising a muffling body, the muffling body having a sound ingress and egress surface, at least one muffling chamber is provided inside the muffling body , the sound ingress and egress surface is provided with at least one communication port, each of the communication port connecting one or more of the muffling chamber, each of the muffling chamber is connected to the outside of the sound ingress and egress surface through at least one of the communication port. In the muffling device and refrigerating and freezing apparatus, when noise passes through the through-holes of the muffling device, the sound is transmitted through the communication ports into the muffling chamber, extending the sound propagation path, weakening the sound energy, and thereby reducing the sound that continues to disperse outward. Specifically, the length of at least one muffling chamber is between 0.0085m to 0.85m. The length of the muffling chamber is set so that the incident sound waves and reflected sound waves at the communication ports of the muffling chamber overlap, with the amplitudes being as equal as possible and the phases being inverted by 180° as much as possible, thus maximizing the cancellation of sound waves to achieve the purpose of muffling or noise reduction.
