    • A refrigerating and freezing device (1) includes a cabinet, wherein at least one storage compartment (11) is defined therein, and a heating cavity is defined in one of the storage compartments (11); and an electromagnetic heating device, configured to supply electromagnetic waves into the heating cavity so as to heat a to-be-processed object in the heating cavity, wherein the electromagnetic heating device is provided with an electromagnetic generation module (21) configured to produce an electromagnetic wave signal. A containing groove (12) with an upward opening is provided in a top of the cabinet (10), the opening of the containing groove (12) is covered with a cover (13) so as to define a containing space (14) between the containing groove (12) and the cover (13), and heat dissipation holes configured to achieve communication between the containing space (14) and an external environment where the cabinet (10) is located are provided in the cover (13). The electromagnetic generation module (21) is disposed in the containing space (14), and a heat dissipation fan (31) is further provided in the containing space (14) and is configured to drive airflow to flow between the containing space (14) and the external environment where the cabinet (10) is located through the heat dissipation holes, so as to dissipate heat from the electromagnetic generation module (21). The heat dissipation efficiency and the heat dissipation effect are improved, and the space inside the cabinet (10) is prevented from being occupied.
