The water receiving shed 300 is provided below the cold storage tank 200, and the water receiving shed 300 is used for receiving the condensed water of the cold storage tank 200.

With this alternative embodiment, the cold storage box 200 exchanges heat with the air in the refrigerating space 110 to lower the temperature in the refrigerating space 110, that is, the temperature in the refrigerating space 110. The cold storage tank 200 is provided at an upper portion of the refrigerating space 110, and a lower portion of the refrigerating space 110 is used for placing the object to be refrigerated. The cool air around the cold storage box 200 sinks to lower the temperature of the air around the object to be refrigerated, thereby satisfying the storage condition of the object to be refrigerated. Meanwhile, the cold air flows to enable the air in the refrigerating space 110 to circulate, the heat exchange efficiency of the cold storage box 200 and the air is improved, the temperature in the refrigerating space 110 is enabled to be consistent, and the situation that the local temperature is higher or lower is reduced.

The temperature is lower in the cold storage box 200, and the vapor in the air meets cold liquefaction, can form the comdenstion water on the surface of cold storage box, and the comdenstion water drips to waiting to refrigerate thing department downwards, drenches easily and waits to refrigerate the thing, treats to refrigerate the thing and causes the damage. This embodiment is including receiving water canopy 300, and the comdenstion water that drips on the cold-storage box 200 can be accepted to the below of cold-storage box 200 is located to water receiving canopy 300, prevents that the comdenstion water from dripping to waiting to refrigerate thing department, treats the refrigerated object and protects.

Optionally, the orthographic projection of the cold storage box 200 on the water receiving shed 300 is entirely positioned in the water receiving shed 300. Thus, the water receiving shed 300 can receive all the condensed water dropping from the cold storage box 200, so that the dryness of the cold storage space 110 for placing the objects to be refrigerated is maintained, the storage condition of the objects to be refrigerated is met, and the objects to be refrigerated are prevented from being damaged.

As shown in fig. 1 to 4, in some alternative embodiments, the housing 100 is configured with a drain hole 140, and the drain hole 140 communicates with the refrigerating space 110. The water receiving compartment 300 is disposed in an inclined manner, and the lowest end of the water receiving compartment 300 is connected to the sidewall of the refrigerating space 110, so that the condensed water can flow to the drain hole 140 along the sidewall of the refrigerating space 110 through the lowest end of the water receiving compartment 300 and flow out of the drain hole 140.

With this alternative embodiment, the water receiving booth 300 is inclined such that the condensed water dropped on the water receiving booth 300 can flow along the water receiving booth 300. The lowest end that connects the water canopy 300 is connected with the lateral wall of refrigerated space 110, and when condensate water flows to the lowest end of water receiving canopy 300, the condensate water can flow to the lateral wall of refrigerated space 110 through the lowest end that connects the water canopy 300. The drain hole 140 communicates with the refrigerating space 110, and water in the refrigerating space 110 can be drained through the drain hole 140.

Optionally, the water receiving shed 300 is bent downward, so that the water receiving shed 300 is shaped like a Chinese character 'ren'. That is to say, the middle part of the water receiving shed 300 is the highest end of the water receiving shed 300, and both ends of the water receiving shed 300 are the lowest ends of the water receiving shed 300. Therefore, the flowing distance of the condensed water on the water receiving shed 300 can be reduced, and the condensed water can quickly flow downwards to the drain hole 140 and flow out of the drain hole 140. Avoid the comdenstion water to persist the time overlength on water receiving canopy 300 for the condition of water receiving canopy 300 hourglass takes place, thereby prevents to damage and treats cold-stored thing, improves cold-storage refrigeration plant's job stabilization nature and reliability.

The orthographic projection of the lowest end of the first blade 311 on the second blade 312 is located in the highest end of the second blade 312, so that the water receiving shed 300 is in a step shape. Therefore, the condensed water can flow from the first blade 311 to the second blade 312, and then flows downwards to the lowest end of the water receiving shed 300, namely, the blade 310 at the lowest position of the water receiving shed 300, so that the condensed water is prevented from leaking out from the gap between the first blade 311 and the second blade 312 and wetting the object to be refrigerated. The gap 330 is formed between the lower wall surface of the first blade 311 and the upper wall surface of the second blade 312, so that the air in the refrigerating space 110 can flow downwards through the gap 330, and the water receiving shed 300 is prevented from blocking the circulation of the air in the refrigerating space 110, thereby ensuring the heat exchange efficiency of the cold storage box 200 and reducing the cooling time of the refrigerating space 110.

The first blade 311 and the second blade 312 in this embodiment are only examples, and the number of the blades 310 is not limited, for example, the plurality of blades 310 further includes a third blade, a fourth blade, and the like.

The inclination directions of the blades 310 are the same as the inclination directions of the partial water receiving shed 300 formed by the blade group where the blades are located, and the two highest blades 310 of the two blade groups are abutted to prevent the condensed water from leaking to the object to be refrigerated.

As shown in fig. 4-6, in some alternative embodiments, the water receiving shed 300 further includes a connection plate 320. The blades 310 are respectively provided at both ends thereof with connection plates 320, the plurality of blades 310 are spaced apart along the extension direction of the connection plates 320, and both ends of the connection plates 320 are respectively connected to two opposite sidewalls of the refrigerating space 110.

With this alternative embodiment, two ends of the connecting plate 320 are respectively connected to two opposite sidewalls of the refrigerating space 110, so that the water receiving compartment 300 is fixedly disposed in the refrigerating space 110, and the connection stability between the water receiving compartment 300 and the refrigerating space 110 is increased. Both ends of the blade 310 are connected to the connection plate 320, respectively, and the plurality of blades 310 are spaced apart along the extending direction of the connection plate 320.

In some alternative embodiments, the blades 310 are provided with a hydrophilic coating, the blades 310 are arranged obliquely, and the inclination angle of the blades 310 is larger than the hydrophilic angle of the hydrophilic coating.

With the alternative embodiment, the blade 310 is provided with the hydrophilic coating which has better hydrophilicity, and the hydrophilic coating can adsorb condensed water to prevent the condensed water from irregularly flowing on the surface of the blade 310. The hydrophilic angle refers to the angle formed by the liquid drop standing on the plane of the aluminum foil or other plate strips, and is called a contact angle. The smaller the angle of hydrophilicity, the better the hydrophilicity. Conversely, the larger the angle of hydrophilicity, the poorer the hydrophilicity. The blades 310 are arranged to be inclined downward, and the inclination angle of the blades 310 is greater than the hydrophilic angle of the hydrophilic coating. Therefore, the condensed water on the blades 310 can be ensured to flow downwards only along the inclined direction of the blades 310, the condition that the condensed water leaks and wets the objects to be refrigerated due to the irregular movement of the condensed water is avoided, and the storage condition of the objects to be refrigerated is met.
