[0144] In some embodiments, the first air outlet 601 is opened on a side of the ventilation shell 500 located in the first chamber 1031 , and the first air outlet 601 faces the first chamber 1031 .

[0145] In some embodiments, the second air outlet 602 is opened on a side of the ventilation shell 500 located in the second chamber 1032 , and the second air outlet 602 faces the second chamber 1032 .

[0146] In some embodiments, the cooling air outlet includes a third air outlet 603, which is opened on the side of the ventilation shell 500 facing the second accommodating cavity 104. The design of the third air outlet 603 allows cold air to flow directly to the second accommodating cavity 104, thereby enhancing the cooling effect of the area, which is beneficial to maintaining the freshness of the items in the second accommodating cavity 104 and extending the shelf life.

[0147] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
