As shown in fig. 5, when the refrigerator is operated, the side condenser radiating pipes generate heat which affects the refrigerating effect of the refrigerator, so that the heat can be recycled for other functions. When food needs to be defrosted, the defrosting valve and the defrosting water pump are opened, when circulating water passes through the heat recovery pipeline with heat on the side surface, the water temperature can rise, the high-temperature circulating water reaches the defrosting area pipeline in the functional area pipeline from the water inlet of the functional area pipeline through the heat recovery pipeline on the side surface, heat transfer can be carried out when the high-temperature circulating water passes through the defrosting area, heat is used for unfreezing food, the water temperature flowing out from the circulating passage of the defrosting area is reduced, and the defrosting water pump is used for pumping low-temperature circulating water to the circulating water outlet of the functional area to reach the heat recovery pipeline. Then the high-temperature water flowing through the side heat recovery pipeline is sent to the pipeline of the thawing area, so that the high-temperature water flows back and forth, and the food thawing function is realized while the temperature of the condenser is reduced through the circulating water flowing through the passage.

When the deicing function is needed, the deicing valve and the deicing water pump are opened, the water temperature rises when circulating water passes through the side heat recovery pipeline, the high-temperature circulating water enters the pipeline of the freezing area and can transfer heat when passing through the freezing area, and ice blocks attached to the freezing area are removed, so that the deicing purpose is achieved. The temperature of the water that flows from freezing district circulation path reduces, utilizes the deicing water pump with microthermal circulating water through the water inlet of side heat recovery pipeline, delivers to the heat recovery pipeline again to reach condenser heat dissipation pipeline cooling and get rid of the effect of frozen layer ice-cube, thereby carry out inside hydrologic cycle and continuously carry out heat-conduction.

The invention also provides a refrigerator comprising the pipeline structure.

The functional areas of the refrigerator 1 specifically include: a cold storage area 13, a freezing area 12 and a unfreezing area 11 which are arranged from top to bottom in sequence. The unfreezing area is arranged on the bottom layer, so that the heat generated during unfreezing is prevented from influencing the refrigerating effect of the freezing area and the refrigerating area.

And the arrangement mode of the freezing area is consistent with that of the unfreezing area.

As shown in fig. 4, if the two sides of the refrigerator generate heat, the left and right sides of the refrigerator can be provided with heat recovery pipelines, and each group of heat recovery pipelines is provided with a group of functional area pipelines, namely, the left heat recovery pipeline corresponds to the functional area pipeline close to the front side of the refrigerator, the right heat recovery pipeline corresponds to the functional area pipeline close to the rear side of the refrigerator, the two groups of functional area pipelines are in front of the refrigerator and are bounded by the center of the rear side of the refrigerator, half of the pipelines are equivalent to one unfreezing area, the other half of the pipelines are equivalent to the other unfreezing area, and the layout mode of the freezing area is also consistent with the layout mode of the unfreezing area.

The number of the heat recovery pipes is determined according to the actual requirement of the refrigerator, and both the arrangement modes are within the protection scope of the invention.

The invention reduces the heat emitted by the condenser when the refrigerator works by circulating water, can improve the heat dissipation effect of the refrigerator and improves the working efficiency of the refrigerator.
