Description

Technical Field

[0001] The utility model relates to the technical field of cold chain transportation, and in particular to a drainage component for a refrigerated compartment and a refrigerated compartment. Background Art

[0002] In some vehicles such as fresh food, refrigerated transport vehicles and sanitation vehicles, liquids are generated during transportation. Although drainage holes are set on the floor of the vehicle to drain the liquids generated by the goods, due to the limitations of the floor structure, the liquids cannot be effectively discharged from the drainage holes and accumulate on the floor, which can easily cause contamination of the goods in the fresh food or refrigerated trucks, and the sanitation trucks cannot effectively discharge the liquids in the garbage during transportation, affecting the subsequent treatment of the garbage and the cleaning of the floor.

[0003] After searching, it was found that the publication number is CN217994593U, and the name is a vehicle floor that is easy to clean. The application proposes that currently only simple drainage holes are set on the floors of refrigerated transport vehicles. After a long time, some impurities in the liquid are easy to block the drainage holes, and there will be odor and insects crawling out. By setting the grooves, the outflowing liquid can quickly flow from the surface of the floor body through the grooves into the drainage holes and be discharged; for fresh or refrigerated vehicles, it can prevent liquid from accumulating on the floor body for a long time, causing pollution of the goods, and greatly improve the cleanliness of the floor body; for sanitation vehicles, it can quickly make the liquid in the garbage discharged from the floor board, which is convenient for the later treatment of garbage; at the same time, a double-layer barrier structure floor drain component composed of a sealing float, a water seal cover and a U-shaped elbow is arranged on the drainage hole, which can block the odor in the drainage pipe from overflowing, and can also prevent insects from entering the floor through the drainage hole, thereby playing a role in preventing odor and insects. However, this application still adopts the method of gravity drainage. Those who have used household sinks have experience that the filter cartridge at the bottom of the sink has a slow drainage speed, and it is very easy to cause water accumulation and blockage, with low drainage efficiency and poor filtering effect. The working principle of this application is similar to that of a household sink, with low drainage efficiency and slow drainage speed, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
