In some specific embodiments, a distance of 5mm to 10mm (e.g., 5mm, 7mm, or 10 mm) can be maintained between the anode plate 330 and the cathode membrane assembly 320, so that not only the reaction efficiency is prevented from being low due to the too large distance between the anode plate 330 and the cathode membrane assembly 320, but also the oxygen generated by the anode plate 330 is prevented from being discharged in time due to the too small distance, which affects the reaction process.
Referring to fig. 8, fig. 8 is an exploded view of a drawer assembly 30 in a refrigerator 1 according to another embodiment of the present invention. In some embodiments, the drawer assembly 30 may further include a barrel 360, the barrel 360 having a drawer space opened forward, the drawer body 200 being drawn out of or retracted into the drawer space, the drawer assembly 30 being further configured such that the cover plate 100 thereof serves as a ceiling of the drawer space.
That is, the cover plate 100 may be used not only independently to cover the storage space 210 of the drawer body 200, but also as a top plate of the drawing space, so that the drawer body 200 may be pulled out or retracted into the drawing space as a whole, and when in the closed position, the drawer body 200 may be entirely positioned in the cylinder 360, and the top plate of the cylinder 360 (i.e., the cover plate 100) covers the storage space 210 thereof, and oxygen in the air in the storage space 210 is consumed by the electrolytic oxygen removing device 300 provided at the top plate of the cylinder 360.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
