In some embodiments, the refrigerator further includes: a second air door 205 and a third air door 206, the second air door 205 being provided at the first air return opening 203 to close or open the first air return opening 203; and/or, the third damper 206 is disposed at the second air return port 204 to close or open the second air return port 204.

By adopting the refrigerator provided by the embodiment of the disclosure, by arranging the second air door 205, the second air door 205 can close or open the first air return opening 203 on one hand, and can adjust the air outlet volume of the first air return opening 203 on the other hand, so as to control the air flow rate of the second accommodating cavity 201; by providing the third air door 206, the third air door 206 can close or open the second air return port 204 on one hand, and can adjust the air output of the second air return port 204 on the other hand, so as to control the air flow rate of the third accommodating cavity 202.

In some embodiments, the second door 30 and the third door 40 are each made of a transparent material.

By adopting the refrigerator provided by the embodiment of the disclosure, the second door 30 and the third door 40 are transparent, so that a user can intuitively see the articles stored in the second accommodating cavity 201 and the third accommodating cavity 202 without opening the second door 30 and the third door 40, and the user can conveniently find the articles.

Alternatively, the transparent material may be glass, acrylic plate, transparent plastic, or the like.

Optionally, labels and/or digital displays are provided on the second door 30 and the third door 40. Thus, the user can intuitively classify and search the articles.

Optionally, the second door 30 and/or the third door 40 are provided with an atomized glass which, during normal use, ensures an opaque state, and which is kept transparent when the user needs to find an internal item. Thus, the user can intuitively classify and search the articles, and the privacy of the user can be protected.

Optionally, a color-changing material is disposed on the second door 30 and/or the third door 40. In this way, the color-changing material on the second door body 30 and the color-changing material on the third door body 40 can be used to present different colors, and the user can be more obviously prompted by using different colors to correspond to different information, so as to improve the convenience of the refrigerator.

For example, a color change material on the second door 30 displaying red indicates that meat is placed in the second receiving cavity 201, and a color change material on the third door 40 displaying green indicates that vegetables are placed in the third receiving cavity 202.

The above description and the drawings illustrate embodiments of the disclosure sufficiently to enable those skilled in the art to practice them. Other embodiments may include structural and other modifications. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in, or substituted for, those of others. The embodiments of the present disclosure are not limited to the structures that have been described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
