A portion of the inner surface 650 of the door body 600 forms the groove 610 by being depressed. The electrolytic oxygen removal device 100 is disposed within the recess 610. In the process of forming the groove 610, the inner surface 650 of the portion of the door body 600 may be recessed in a normal direction of the inner surface 650 of the door body 600. When the door body 600 closes the storage compartment 210, the inner surface 650 of the door body 600 faces the inner space of the storage compartment 210; when the door 600 opens the storage compartment 210, the inner surface 650 of the door 600 may be exposed to the external environment of the refrigerator 10.

The exhaust passage 620 extends upward from the connection hole 611 to the top of the door body 600. The extending direction of the broken line arrow in fig. 7 shows the extending direction of the exhaust passage 620. Fig. 8 is a partial enlarged view at B in fig. 7, showing the communication port 631 of the exhaust passage 620 communicating with the external environment.

The exhaust channel 620 is disposed on the door body 600 instead of the refrigerator body 200, and the exhaust channel 620 extends from the connection hole 611 of the groove 610 to the top of the door body 600, and since the cold air easily sinks, the exhaust channel 620 extends from bottom to top, so that the loss of the cold in the storage compartment 210 through the exhaust channel 620 can be further reduced or avoided, and the heat preservation effect of the refrigerator 10 can be improved. In other embodiments, the exhaust passage 620 may be formed to extend from the connection hole 611 of the groove 610 toward the side of the door body 600.

Wherein the bottom bracket 310 is disposed at the bottom of the drawer assembly 300 and is fixedly connected to the inner surface 650 of the door body 600. For example, the front end of the shoe 310 may be connected to the inner surface 650 of the door body 600 by a rivet 350. In this embodiment, two rivets 350 are provided, and connect one end of the bottom bracket 310 and the inner surface 650 of the door body 600, respectively, and the two-way arrow in fig. 9 shows the transverse extending direction. The recess 610 may be located intermediate the two rivets 350, with the bottom wall of the recess 610 being higher than the upper surface of the shoe 310, to avoid the shoe 310 from obscuring the recess 610. In some embodiments, the bottom wall of the recess 610 may also be higher than the tray 320 to avoid the tray 320 from obstructing the recess 610.

The tray 320 is disposed on the bottom base 310 for lifting a container 330 described below. For example, the tray 320 may be removably disposed on the shoe 310. The container 330 is detachably disposed on the tray 320 and faces the electrolytic oxygen removing device 100, and a storage space 331 for storing articles is formed inside the container 330. And a vent hole 332 is formed on the side of the container 330 facing the electrolytic oxygen removing device 100, so that the gas in the storage space 331 can flow to the electrolytic oxygen removing device 100 through the vent hole 332 to serve as a reactant of the cathode plate 120. Fig. 10 is an enlarged view of a portion of fig. 3 at a, showing the vent holes 332.

Since the tray 320 and the containers 330 are detachably mounted on the connecting plate, either directly or indirectly, the tray 320 and the containers 330 can be easily removed when it is desired to disassemble the electrolytic oxygen removing device 100.

Tray 320 includes a bottom tray 310, side panels 322, and a back panel 323. The shoe 310 is located at the bottom of the tray 320.
