Fig. 1 is a schematic structural view of an oxygen reduction device 1000 for a refrigerator according to the present utility model, as shown in fig. 1, and referring to fig. 2 to 3, an embodiment of the present utility model provides an oxygen reduction device 1000 for a refrigerator for consuming oxygen in a storage chamber of a refrigerator. The oxygen reduction device includes a receiving chamber. An electrolyte is arranged in the accommodating cavity. A vertical strip-shaped perspective area is arranged on the side wall of the accommodating cavity and used for observing the liquid level of the electrolyte.

The fluid-filled column 1300 is vertically disposed, has a fluid-filled hole 1310 coaxial with the fluid-filled port 1120, and communicates with the fluid-filled port 1120. The main purpose of the fluid infusion column 1300 is to reduce the overflow of electrolyte caused by excessive fluid infusion during the fluid infusion of the oxygen reduction device 1000.

In some embodiments of the present utility model, as shown in FIG. 1, the oxygen reduction device 1000 further includes an outlet pipe 1500.

The outlet section 1421 is tapered, so that a user can more easily align the outlet of the fluid replacement device 1400 with the fluid replacement hole 1310 on the fluid replacement column 1300 when fluid replacement is performed. Of course, in other embodiments, the reservoir may be rectangular or have other shapes.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the liquid outlet tube 1420 further includes a straight tube section and a curved section 1422 connecting the outlet section 1421 and the straight tube section. The liquid outlet pipe 1420 can also be arranged in a shape comprising a straight pipe section and a bending section 1422, and the arrangement is such that when the user is carrying out liquid filling, even if the liquid storage barrel can not be arranged vertically and can only be used for carrying out water filling due to space problems, the tapered outlet section can still be inserted into the liquid filling hole, and the situation that electrolyte drops fall outside is avoided.

In some embodiments of the utility model, as shown in fig. 1 and 2, the reservoir 1410 has a reservoir volume that is no greater than the volume of the receiving chamber. The maximum water storage capacity of the fluid infusion tube 1410 does not exceed the volume of the accommodating cavity of the oxygen reduction device 1000, so that the situation that the oxygen reduction device 1000 is fully filled and overflows when the fluid infusion tube 1410 is used for infusing fluid into the accommodating cavity of the oxygen reduction device 1000 can be avoided to a certain extent, and the operation of a user is simpler.
