[0088] Since the drawer assembly 100 is a closed area with no lighting inside, when the drawer is pulled out, the light deep inside the drawer is not sufficient, which affects the visual effect; and the storage of food often also requires a sterilization mode. Based on this, in the above embodiment, a lamp assembly 6 is set on the side of the drawer 2, and the lamp assembly 6 has a lighting mode and an ultraviolet sterilization mode. When the drawer 2 is just pulled out, the lamp assembly 6 switches to the lighting mode, so that the drawer is open with sufficient light, which is convenient for taking or storing food. After the drawer 2 is put into the outer frame 1, the lamp assembly 6 switches to the ultraviolet sterilization mode to play a sterilization role. Therefore, the setting of the lamp assembly 6 is not only conducive to taking or storing food, but also conducive to the sterilization and preservation of items in the drawer assembly 100.

[0089] In some embodiments, the lamp assembly 6 is configured to switch to the ultraviolet sterilization mode and turn off the ultraviolet sterilization mode after a second preset time has passed.

[0090] In the above embodiment, the lamp assembly 6 switches to the ultraviolet sterilization mode in response to the drawer 2 being closed, and then turns off the ultraviolet sterilization mode after reaching the second preset time, which is beneficial for having enough time to complete the sterilization of the items in the drawer assembly 100.

[0091] The ultraviolet sterilization mode of this application is enabled when the drawer is closed, and is turned off when the drawer is opened, which plays a sterilization role. It switches to normal lighting mode when the drawer is opened, ensuring the storage and quality of food while improving the user experience.

[0097] refer to Figure 3 In some embodiments, the drawer assembly 100 also includes a sensor 71 and a controller 72. The controller 72 is electrically connected to the sensor 71. The sensor 71 is configured to detect the actual temperature inside the outer frame 1. The controller 72 is configured to receive the actual temperature sent by the sensor 71, and when the actual temperature is greater than a preset temperature, issue an instruction to deliver cold air to the outer frame 1.

[0098] In the above embodiment, the actual temperature inside the outer frame 1 is detected by the sensor 71, and the actual temperature sent by the sensor 71 is received by the controller 72, and the controller 72 compares the actual temperature with the preset temperature preset therein. When the actual temperature is greater than the preset temperature, it indicates that the actual temperature inside the drawer assembly 100 is too high and needs to be cooled. Therefore, an instruction to deliver cold air to the outer frame 1 is issued. At this time, cold air can be delivered to the outer frame 1 through the refrigeration equipment 400, and the cold air is guided to flow along the outer surface of the outer frame 1 through the air guide assembly 3 to cool the items in the drawer 2 and improve the freshness of the items in the drawer assembly 100.

[0099] In some embodiments, the drawer assembly 100 also includes a temperature compensation member 73 disposed on the outer frame 1, and the temperature compensation member 73 is electrically connected to the controller 72. The controller 72 is configured to control the temperature compensation member 73 to open when the actual temperature is less than the preset temperature and the difference is within the preset temperature range.

[0100] In the above embodiment, the controller 72 compares the actual temperature transmitted by the sensor 7 with the preset temperature preset in the controller 8. When the actual temperature is lower than the preset temperature and the difference is within the preset temperature range, it indicates that the temperature inside the drawer assembly 100 is too low, which is not conducive to the preservation of the items in the drawer assembly 100. Therefore, the temperature compensation component 73 is controlled to open and the temperature inside the drawer assembly 100 is adjusted so that the temperature inside the drawer assembly 100 can be stabilized within a preset reasonable temperature range.
