In some embodiments of the present invention, a temperature sensor can be disposed in each drawer 30 to detect the temperature change in the corresponding drawer 30, so that air can be supplied only when the drawer 30 needs to supply air, thereby preventing overcooling of food and saving energy.

In some embodiments of the present invention, the user can also determine the number of the drawers 30 according to his/her own needs, and the user can directly place the articles in the first space 21 where the drawers 30 are not placed. For example, the number of the first space 21 and the number of the drawers 30 are both 6, and a user can place 4 drawers 30, 2 drawers 30, and the like according to the requirement. The positions of the 6 drawers 30 can be arbitrarily switched. Each drawer 30 may be designed as a sealing structure except for the intake opening 31 and the return opening 32 to prevent the temperature of the air flow between the drawers 30 from interfering with the smell and the like. Further, the bottom wall front end of each first space 21 is provided with a stop bar 25, and the bottom front end of each drawer 30 is provided with a stop groove or a stop surface which is engaged with the corresponding stop bar 25, so that each stop bar 25 obstructs the drawer 30 from moving forward after the corresponding drawer 30 is located in the corresponding first space 21.
