Optionally, the drawer for a refrigerator further comprises: a first sensor 60 and a controller 70, wherein the first sensor 60 may be installed in the window 21 or in the storage space 11 for detecting a state of the articles stored in the storage space 11. The status of the item includes the type of the item, for example, the type of the item is fruit, red wine, or other types of food materials. Referring to fig. 6, the controller 70 is electrically connected to the first sensor 60 for receiving the state of the article detected by the first sensor 60. The controller 70 is also electrically connected to the projection device 40 for controlling the projection device 40 to project light of different colors according to the state of the article. For example, when fruits are placed in the storage space 11, the controller 70 controls the projection device 40 to emit violet light; when red wine is placed in the storage space 11, the controller 70 controls the projection device 40 to emit yellow light; the different colors of light represent different kinds of food materials, and different atmospheres are created by projecting the different colors of light so as to inform a user of the state of the stored goods in the storage space 11.

Optionally, the drawer further comprises: a second sensor 80. the second sensor 80 is used to detect the horizontal distance between the user and the window 20. The second sensor 80 may be installed in the middle of the left and right door bodies of the refrigerator, for example, if the drawer is a temperature change region drawer, the temperature change region drawer is generally adjacent to the cooling region drawer, so the second sensor 80 may be installed at the uppermost position in the middle of the left and right door bodies of the cooling region drawer. With continued reference to fig. 6, the controller 70 is also electrically connected to the second sensor 80 for receiving the distance detected by the second sensor 80 and controlling the projection device 40 to project different colors of light indicating the status of the articles or project pictures in the storage space 11 according to the distance. When the second sensor 80 detects that the distance between the user and the window 20 is within a first preset distance range, the controller 70 controls the projection device 40 to project light of different colors to indicate the status of the article, and when the second sensor 80 detects that the distance between the user and the window 20 is within a second preset distance range, the controller 70 controls the projection device 40 to project a picture in the storage space 11. The first preset distance range is greater than the second preset distance range, when the distance between the user and the window 20 is within the first preset distance range, the distance between the user and the window 20 is relatively long, that is, the distance between the user and the refrigerator is relatively long, even if the projection device 40 projects the picture in the storage space 11, the user cannot see the picture displayed by the display device 50 clearly, so at this time, the controller 70 controls the projection device 40 to project light of different colors to indicate the state of the articles stored in the storage space 11, so that the user can know the type of the food materials stored in the storage space 11; when the distance between the user and the window 20 is within the second preset distance range, the distance between the user and the window 20 is relatively short, that is, the distance between the user and the refrigerator is relatively short, and the user can clearly see the picture displayed by the display device 50, so at this time, the controller 70 controls the projection device 40 to project the picture in the storage space 11, so that the user can know the specific food materials stored in the storage space 11. For example, the first predetermined distance range is 4-5 meters, and the second predetermined distance range is 1-4 meters; when second sensor 80 detects that the distance between the user and window 20 is within 4-5 meters, controller 70 controls projection device 40 to project a different color of light to indicate the status of the item; when the second sensor 80 detects that the distance between the user and the window 20 is within 1-4 meters, the user cannot see the picture in the storage space 11 through the window 21 due to the problem of the viewing angle, so the controller 70 controls the projection device 40 to project the picture in the storage space 11. The first preset distance range and the second preset distance range may be set according to actual needs, and this embodiment does not limit them at all.

Alternatively, the different colored lights are all pure colored lights, which can also be used as searchlights to illuminate the window 21 while indicating the status of the item.

Optionally, the controller 70 is further configured to control the projection device 40 to turn off according to the distance detected by the second sensor 80. When the second sensor 80 detects that the distance between the user and the window 20 is within the third preset distance range, the controller 70 controls the projection device 40 to be turned off without displaying any color or picture. For example, the third preset distance range is 0-1 meter, and the distance range represents that the distance between the user and the window 20 is very close, that is, the distance between the user and the refrigerator is very close; when the second sensor 80 detects that the distance between the user and the window 20 is within 0-1 meter, the controller 70 controls the projection device 40 to be turned off. The third preset distance range is set according to actual needs, and this embodiment does not limit this range at all.

Optionally, the drawer for a refrigerator further comprises: a third sensor 100, the third sensor 100 being used to detect whether the user opens the drawer cabinet 10. With continued reference to fig. 6, the controller 70 is further electrically connected to the third sensor 100 to receive the detection result of the third sensor 100 and control whether the projection device 40 is turned off according to the detection result. If the third sensor 100 detects that the user opens the drawer cabinet 10, the controller 70 controls the projection device 40 to be turned off without displaying any color or picture. If the third sensor 100 detects that the user does not open the drawer cabinet 10, the controller 70 controls the projection device 40 to project a different color indicating the status of the article, or controls the projection device 40 to project a picture in the storage space 11, or controls the projection device 40 to close, according to the distance between the user and the window 20 detected by the second sensor 80.

It should be noted that when the user opens the drawer cabinet 10, the distance between the user and the window 20 is necessarily within the third preset range, so the controller 70 controls the projection device 40 to close according to the distance detected by the second sensor 80 or according to the user opening the drawer cabinet 10 detected by the third sensor 100; after the user opens the drawer cabinet 10, the user leaves the refrigerator without closing the drawer cabinet 10, and the distance between the user and the window 20 exceeds the third preset distance range, but since the drawer cabinet 10 is in the open state at this time, the controller 70 still controls the projection device 40 to be closed.

Optionally, referring again to fig. 3, 5 and 6, the drawer for a refrigerator further comprises: transparent guard plate 90, transparent guard plate 90 cover in the outside of window 21 to be connected with window body 20, in order to avoid in the window 21 and the surface area of first transparent board 51 to fall the dust, simultaneously, transparent guard plate 90 is transparent, does not hinder user's observation sight.
