The electromagnetic fresh-keeping structure comprises: a first housing (20), comprising a first accommodating space (210); and a second housing (40) provided in the first accommodating space (210) and used for partitioning the first accommodating space (210) into a plurality of sub-accommodating spaces (211). The plurality of sub-accommodating spaces (211) comprise a first sub-accommodating space (2111) and a second sub-accommodating space (2113). The second housing (40) comprises a first side wall (410), and the first sub-accommodating space (2111) and the second sub-accommodating space (2113) are respectively located on two opposite sides of the first side wall (410). The first sub-accommodating space (2111) is used for storing articles. The electromagnetic fresh-keeping structure also comprises at least one electromagnetic coil assembly (60). The electromagnetic coil assembly (60) is disposed in the second sub-accommodating space (2113). The first housing (20) is provided with a first air vent (201) and a second air vent (202). The first air vent (201) and the second air vent (202) are located on the same side of the first accommodating space (210). The first air vent (201) is in communication with the second sub-accommodating space (2113), and the second air vent (202) is in communication with the first sub-accommodating space (2111). The first side wall (410) is provided with a plurality of through holes (403). In this way, uniform heat dissipation of the electromagnetic coil assembly (60) and the stored articles can be achieved.
