Claim 0:
1. A refrigerating and freezing device, comprising:
a cabinet, defining at least one storage compartment;
at least one cabinet door, configured to respectively open and close the at least one storage compartment;
a refrigerating system, configured to provide cooling capacity to the at least one storage compartment; and
a heating unit, wherein the heating unit comprises:
a container body, disposed in one of the storage compartments and provided with a pick-and place opening;
a door body, disposed at the pick-and-place opening and configured to open and close the pick-and-place opening; and
an electromagnetic generating system, at least a part of which is disposed in the container body or accessed into the container body, so as to generate electromagnetic waves in the container body to heat an object to be processed; and the refrigerating and freezing device further comprising:
a cabinet door detection device, configured to detect open and closed states of the cabinet door corresponding to the storage compartment provided with the container body; and the electromagnetic generating system stopping generating electromagnetic waves when a corresponding cabinet door is in an open state;
wherein the heating unit further comprises a door body detection device, configured to detect open and closed states of the door body; and the electromagnetic generating system stopping generating electromagnetic waves when the door body is in an open state;
wherein the electromagnetic generating system comprises:
an electromagnetic generating module, configured to generate an electromagnetic wave signal;
a radiating antenna, disposed at a bottom of the container body and electrically connected with the electromagnetic generating module so as to generate electromagnetic waves in the container body; and
a signal processing and measurement and control circuit, disposed at the bottom of the container body and located on a rear side of the radiating antenna, and configured to receive electrical signals of the cabinet door detection device and the door body detection device and enable the electromagnetic generating module to stop working when it is determined that the corresponding cabinet door is in an open state or the door body is in an open state;

wherein the heating unit further comprises a housing configured to separate an inner space of the container body into a heating chamber and an electrical appliance chamber, the heating chamber being configured to place the object to be processed, and the electrical appliance chamber being configured to place the radiating antenna and the signal processing and measurement and control circuit;
wherein a rear part of the housing is configured to protrude upward to form an enlarged space below the housing; and
wherein the door body detection device is fixed to a front wall of an upward protruding part of the housing.
