Abstract

An embedded refrigerator, comprising a refrigerator body, a ventilation structure, and an adjustment apparatus. The refrigerator body comprises a heating component located at the bottom of the refrigerator body, and the ventilation structure is disposed at the bottom of the refrigerator body to form a space at the bottom of the refrigerator body, so as to enable the heating component to perform heat dissipation. The adjustment apparatus is used for connecting the refrigerator body and the ventilation structure, and adjusting a gap between the refrigerator body and the ventilation structure. The embedded refrigerator can adjust a distance between the refrigerator body and the ventilation structure according to the height of a base of the refrigerator, without needing to change a different ventilation structure according to the base having a different height, such that the universality is strong, and there is no need to change the ventilation structure frequently. For example, when the base is higher, the gap between the ventilation structure and the refrigerator body can be appropriately adjusted to be larger; and when the base is lower, the gap between the ventilation structure and the refrigerator body can be appropriately decreased or eliminated.
