Description

Technical Field

[0001] The invention relates to the technical field of refrigerators, and in particular to a portable refrigerator. Background Art

[0002] A convenient refrigerator, also known as a portable refrigerator, is a small, easy-to-carry refrigeration device that is very suitable for outdoor use, rental housing, dormitories or offices. However, in actual use, if it is moved, it is easy to cause injury to the operator, and the shell is also damaged due to collision with objects. At the same time, a sealing gasket is mostly used to seal between the upper cover and the box body, and the sealing effect is general. After long-term use, the sealing gasket will wear out, which will further reduce the sealing effect. In addition, the heat dissipation of the refrigerator usually uses a panel plus a heat dissipation hole to dissipate heat. The heat dissipation effect is general. At the same time, the heat dissipation hole is easily blocked by dust, and dust will enter the interior and infect internal components. Therefore, the present application provides a convenient refrigerator to meet the needs. Summary of the invention
