When the oxygen control module 5 is used to add oxygen to the inside of the drawer cavity assembly 41, it can provide the oxygen needed for breathing for the live crabs, live shrimps, etc. placed in the drawer assembly 42, so as to keep the live crabs, live shrimps, etc. fresh. Extend shelf life.

Referring to FIG. 8 , the water storage box 54 is fixed to the top of the sealing frame 53 . The water storage box 54 is communicated with the electrolyte storage tank formed by the anode sheet 52, the sealing frame 53 and the water storage box 54, so that the water in the water storage box 54 can flow into the electrolyte storage tank, which is an electrolyte storage tank. The electrolyte in the supplementary water.

The front side of the water storage box 54 is provided with a docking nozzle 541 for docking the water supply pipe 6 .

The butting nozzle 541 can be specifically a short tube with a rectangular cross section. The left and right widths of the docking nozzle 541 may be the same as the left and right widths of the water storage box 54 , thereby increasing the cross-sectional area of the docking nozzle 541 and making the water flow more smooth during water injection.

The water storage box 54 is provided with a liquid level sensor (not shown in the figure), and the liquid level sensor is fixed at a preset height in the water storage box 54 . When the liquid level in the water storage box 54 is lower than the preset height, it means that the water in the water storage box 54 is less than the set amount. Water reminder.

Referring to FIGS. 9 and 10 , the water adding pipe 6 includes a water pipe main body 61 and a water collecting tank 62 .

The water collecting tank 62 is fixed below the water injection hole 4151 . The water collecting tank 62 has a groove-like structure with an upper opening. The upper opening of the water collecting tank 62 is facing the water injection hole 4151, and the shape and size of the water injection hole 4151 are equal to or slightly larger than the water injection hole 4151. The water collecting tank 62 is used to collect the liquid injected from the water injection hole 4151 .

The water collecting trough 62 may be an integral structure with the reinforcing member 4152 disposed under the front edge of the top cover plate 415, thereby increasing the overall structural strength and reducing the structural complexity.

One end of the water pipe body 61 communicates with the water collecting tank 62 , and the other end communicates with the docking nozzle 541 of the water storage box 54 , so that the water collected from the water collecting tank 62 can be transported to the water storage box 54 .

The elbow design of the transition section 612 can keep the body section 611 away from the right side plate 412 when the sump 62 is disposed close to the right side plate 412 , thereby preventing the body section 611 from interfering with the structure on the right side plate 412 .

In some embodiments, the transition section 612 may also have other shapes corresponding to the body section 611 in cross-section.

In combination with the above structural settings, a use process of the refrigerator of the present disclosure is as follows:

When the liquid level sensor in the water storage box 54 senses that the liquid level in the water storage box 54 is lower than the predetermined height, it sends out a sensing signal, and then controls the horn or the prompt light to send a water-filling prompt to the user.

After the user hears the sound of the water-filling prompt from the speaker or sees the prompt light from the prompt light, the user flips up the hole cover 7 provided at the front end of the top cover plate 415 to open the water-filling hole 4151 . The user can add water to the water collecting tank 62 through the water filling hole 4151.

The water added into the water collecting tank 62 is transferred backward to the water storage box 54 through the water pipe main body 61 . If the electrolyte holding tank of the oxygen control module 5 is not full of electrolyte, the water added to the water storage box 54 will directly flow downward into the electrolyte holding tank until the electrolyte holding tank is full of electrolyte. If the electrolyte holding tank has been filled with electrolyte, the water that is continuously added will be stored in the water storage box 54 .

After the water storage box 54 is full of water, the continuously added water will be stored in the water adding pipe 6 . The water adding pipe 6 is long and designed to be rectangular in cross section, so that more water can be stored in the water adding pipe 6, thus the frequency of adding water can be greatly reduced, and the use is more convenient.

The user can control the start and stop of the oxygen control module 5 through the control buttons provided at the front end of the top cover plate 415 , so as to control the oxygen concentration in the oxygen control and fresh-keeping bin 4 as required.

While the present disclosure has been described with reference to several exemplary embodiments, it is to be understood that the terminology used is of description and illustration, and not of limitation. Since the present disclosure may be embodied in various forms without departing from the spirit or spirit of the disclosure, it is to be understood that the above-described embodiments are not limited to any of the foregoing details, but are to be broadly defined within the spirit and scope of the appended claims. Therefore, all changes and modifications that come within the scope of the claims or their equivalents should be covered by the appended claims.
