Technical Field
[0001] The utility model belongs to the technical field of refrigeration and heat preservation, and particularly relates to a portable refrigerator which is easy to move. Background Art
[0002] As people's demand for outdoor activities continues to increase, portable refrigerators, as a common storage device, are widely used in camping, fishing, picnics and other scenarios. Traditional portable refrigerators usually adopt a single-layer structure, which has poor thermal insulation and shock absorption effects and cannot meet users' needs for long-term refrigeration and item safety. In addition, the internal structure of existing refrigerators is single and cannot effectively separate and store different types of items. It is easy to cause problems such as confusion of items and poor refrigeration effect during use.
[0003] 1. Disadvantages of single-layer design
[0004] Traditional portable refrigerators mostly adopt a single-layer structure, which has limited insulation effect. During long-term use, the temperature inside the refrigerator will rise rapidly, affecting the preservation effect of the items. At the same time, the single-layer refrigerator is easily affected by external impact during transportation, causing damage to the items in the box and failing to effectively protect the safety of the items.
[0005] 2. Simple internal structure
[0006] Existing portable refrigerators usually have simple internal structures and lack effective partitioning and storage functions. During use, it is difficult for users to classify and store different types of items, resulting in confusion and inconvenience. In addition, existing refrigerators lack specially designed refrigeration and drainage devices, and cannot maintain a dry and low-temperature environment inside the box, affecting the refrigeration effect.
[0007] 3. Lack of effective drainage design
[0008] During the use of traditional portable refrigerators, condensation and other liquids are easily generated in the box, but the lack of effective drainage design leads to water accumulation in the box, affecting the drying and preservation of items. The accumulated water is not only easy to breed bacteria, but also accelerates the temperature rise in the refrigerator, further reducing the refrigeration effect. Utility Model Content
[0009] The main purpose of the utility model is to provide a portable refrigerator that is easy to move and can effectively solve the problems in the background technology.
[0010] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0038] In this embodiment, the water-permeable holes 204 at the bottom of the inner box body 201 are evenly distributed to ensure drainage effect.
[0039] The utility model forms an air layer between the outer shell and the inner box to form a double-layer design, which significantly improves the heat preservation effect of the refrigerator. The air layer acts as an insulating layer to reduce heat conduction, so that the temperature inside the refrigerator can be kept below the ambient temperature, extending the heat preservation time of the refrigerator. During transportation, the double-layer design can also absorb and disperse external impact forces to protect the safety of items in the box. After actual testing, after adopting the double-layer design, the heat preservation time of the refrigerator is extended from the original 8 hours to more than 12 hours, and the shock absorption effect is improved by about 30%.
[0040] The utility model provides water-permeable holes at the bottom of the inner box to ensure that condensed water and other liquids in the box can be discharged smoothly to maintain a dry environment. The water-permeable holes are designed to be evenly distributed holes, which not only do not affect the sealing of the refrigerator, but also effectively prevent water accumulation inside, ensuring the dryness and hygiene of stored items. During use, the design of the water-permeable holes significantly reduces the humidity in the refrigerator, effectively avoiding the problem of items getting damp due to water accumulation, and making the environment in the refrigerator more suitable for storing items.
