Refrigerator with a door

Technical Field

The utility model relates to a refrigeration technology field, more specifically say, relate to a refrigerator, for example portable refrigerator.

Background

Refrigerators are devices for maintaining freshness of foods at a low temperature (e.g., cold storage) which are common in daily life, and one of the key points of such devices is heat insulation performance of a cabinet, which is essential for temperature maintenance, cooling performance, and power consumption of the refrigerator.

In the current refrigerator, conventionally, as shown in fig. 1, a foamed PU insulation layer is formed between an inner container and an outer casing of the refrigerator to ensure the insulation performance of the refrigerator; or, as shown in fig. 2, in addition to the foamed PU insulation layer, four straight Vacuum Insulation Panels (VIP) are further introduced to cover four sidewalls of the inner container, respectively, so as to improve the insulation capability of the refrigerator through the addition of the vacuum insulation panels.

Although the combination of four vacuum insulation panels covering the four side walls of the liner and the foamed PU insulation layer, respectively, as shown in fig. 2, may improve the insulation capability to some extent, the applicant has found that such improvement is still not desirable because the thermal boundary effect and the thermal bridge effect of each of the four vacuum insulation panels cause heat loss (due to the gradual reduction of the thermal insulation capability of the vacuum insulation panels from the middle to the end edges thereof) and the four corners of the liner are not covered by the vacuum insulation panels.
